<P>The construction electricity technology development, is along with the construction technology development, the electrical science and technology development but synchronization. In particular along with the information technology development, like the computer technology, the control technology, the digital technology, the demonstration technology, the network technology as well as the modern communication development, caused the building electricity technology to realize the leap development. Since the reform and open policy, with on international has carried on the widespread technological exchange, on the international many advanced new products, the new technology unceasingly enter the China construction market, causes the building electricity profession to step out to be new step. At the end of the 70's, the construction profession is one of our country big pillar industries, the construction electricity specialized is at the non- standard standard, the non- technical periodical, the not specialized academic society, the non- scientific research institution, the non- information exchange condition, this and the state economy development is very not symmetric. Construction electricity specialized existence above question does not solve, the potential essential tows the construction profession the hind leg. After the short several year time, this situation obtained huge having a new look. The universities, colleges and institutes successively specialized open in the electrical automation with the construction electricity related foundation curriculum; Established the Chinese construction academic society to construct the electrical academic committee, the national construction electricity design technological cooperation and the information hands over the drift net, publishes "the Construction Electricity" the magazine, a sign "Construction Electricity Design Technology Regulations" also promulgated in 83 years. In order to construct the electrical specialized design next development to build the solid foundation, became impels the building profession synchronization development the power. Various provinces and cities one after another have also established the corresponding academic organization in this foundation, for this local construction electricity development and the progress great effort, through the introduction, in the exchange construction electricity design new technology, had achieved the raise in office general technical personnel service enhances a fruitful way. Along with reform and open policy unceasingly thorough, with the international technical contact, the cooperation is even more frequent, after the 70's last stages Nanjing Jinling hotel opening remarks high-rise construction domestic and foreign cooperations design precedent, in places such as <st1:State w:st="on">Guangdong</st1:State>, Shenzhen, <st1:City w:st="on">Shanghai</st1:City>, <st1:City w:st="on"><st1:place w:st="on">Beijing</st1:place></st1:City> one after another has constructed one batch of high-rise constructions one after another. Some are cooperates the design, some is the domestic designing department independently completes. The general designing department in abundance felt the construction electricity technology the development speed is quick, is we closes the borders and practice isolationism the such many years institute initial expectations to be inferior to. We may review reform and open policy initial period construction zone the situation, the country are close to Hong Kong and Macao the coastal city to take the reform and open policy the window, the national many provinces and cities construction design institutes by open the branch, the company in the coastal special zone took understands new technical the window. This kind of action, in truly played at that time the good role, caused us further to see own disparity, also gradually has found out the overseas construction electricity development situation. Through with the overseas colleague's exchange, introduces the new product, the new technology uses to construct. Promoted and sped up our country construction electricity technology progress. After many years development, along with the capital construction advancement, the construction electricity technology obtained the full development in the national scope. South Xiaoping Comrade patrolled in particular after 1992 the speech, the process brought order out of chaos, recognizes the direction, the national capital construction situation lasted more than ten years, by the tendency which focuses attention on the world continues high speed to develop, enable the building electricity profession to have the considerable progress. The construction electricity including the strong electricity and the weak electricity two parts, the strong electricity partial designs content mainly includes: Changes the electrical power distribution system, the electric power and the lighting system, the anti-radar earth system and so on. Generally speaking, in the construction changes the electrical power distribution system mainly to include: High and low pressure system, transformer, emergency power supply system and so on; The electrical power system mainly includes the electrical power system power distribution and the control; The lighting system includes inside and outside the room each kind of illumination; Anti-radar earth system including anti-radar electric wave invasion, anti-radar , earth, equipotential joint and partial equipotential joint, assistance equipotential joint and so on. In this short more than 20 years, these systems technologies and the product have had the huge change, many designs ideas have also had the huge change along with it. For example in the high tension system high-voltage switch cabinet, its most early uses the circuit breaker is an oil circuit breaker, latter gradually develops the few oil circuit breakers, not only the volume is big, moreover does not protect from fire. Disposes the high-voltage switch cabinet volume is big, but also must independently establish in own compartmentedly in, has taken the very big floor space. Now uses vacuum circuit-breaker and SF6 circuit breaker, not only volume small, moreover short-circuits the capacity also high, the cabinet body size has been also smaller than the original cabinet many, because the circuit breaker does not have any oil, the fire protection performance greatly enhances, and may altogether set at in a room with other low pressure equipment, both has saved the space, and has facilitated the management. The low-voltage circuit-breaker from past volume big, short-circuited the capacity slightly to develop the big electric current, the high score breaks the ability, the volume slightly, the performance stable, causes the system safely reliable, and brought to the design has been convenient. The recent years low-voltage circuit-breaker faces the intellectualized direction to develop, may the circuit breaker many kinds of parameters through the industry control bus, directly transmit the signal for the computer. The doing -like transformer appearance, has brought enormous convenient for the construction electricity design, because does not exist because the transformer oil divulges has the fire possibility, enables it to be allowed conveniently to establish in building in, directly penetrates into the load center. Moreover also eliminated in the construction to the oil transformer capacity limit, in the construction the doing -like transformer has been allowed to use large capacity. In once has designed in the project, has used 4 2500kVA doing -like transformer. The emergency power supply uses the power set, looked from its performance and the volume that, all had the past is very greatly progressive than. Besides uses the diesel oil power set in the project, took the emergency lighting, may use EPS, regarding permission severance power supply in millisecond level equipment, then may use UPS. The power equipment control, solely continued the electricity control from past to move towards the automatic control outside, except each kind of primary device performance better, the volume was small, causes the control box body volume to reduce, mainly was because has used the numeral technical control, caused to control the equipment to be at the optimizing control condition, further has achieved the energy conservation effect. The lighting engineering was is unitary, in the photosource from the past photosource and the lamps and lanterns efficiency low condition moved towards a broader prospect. At present photosource which uses in the construction, has the many kinds of varieties to be possible to supply the choice, the photosource to face the luminous efficiency high, the light color is being good, the colored index high direction develops, the lamps and lanterns also unceasingly are enhancing its efficiency and the form, favor each kind of different situation the application. The photosource appendix, for example uses in the fluorescent lamp ballast, developed from the past ordinary inductance type ballast to the energy conservation inductance ballast, the electronic ballast, moreover in view of the harmonic component size, produced the low overtone electron ballast. The multitudinous photosource, the appendix and the lamps and lanterns, can satisfiedly design personnel's each kind of choice and the design, and fully satisfies each kind of building, each kind of place to the illumination request. No matter is in the room work illumination or the decorative lighting, no matter is the path and garden outside illuminates or the building flood lighting, does not have one did not demonstrate the illumination technology the development the convenience and the advantage which brings for the construction illumination. Moreover other installments and equipment which uses in the electrical design, for example the double power source mutually cuts mutually throws the switch, also moved towards the specialized production from the traditional product, besides satisfies conventional the power source cut, but also appeared has been able to satisfy the electronic installation double power source mutually to throw, can product which in mutually threw in 1/4 power sources, greatly enhanced the power supply reliability and the continuity. The power supply cable and the wire constructs the product which in electricity massively uses. The examination past electric cable and the wire sample, its variety appeared deficiently, but the present, each kind of cable line unceasingly promotes, to anti- burnt from the ordinary PVC cable line, is fireproof, the low smoke non- halogen exposure environmental protection cable line; Expects the mineral insulation from the ordinary insulation; From ordinary insulation generatrix to enclosed generatrix, pre- branching cable and so on. These technologies for the construction electricity security, reliable, were convenient, the environmental protection have provided the powerful safeguard. In view of the special construction power distribution demand, some new installments also obtain the widespread application. For example the large-scale hospital operating room uses the medical place the leakage protection, surplus electric current supervisory system and so on. The strong electricity system technological development, is the general engineers and technicians is obvious to all, also is our institute by oneself experience. The so huge development, has laid the good foundation for our country construction electricity construction, also used electricity for the construction security has created the condition. Along with the construction intellectualization technology deepened application, some equipment or the system control, gradually moves towards by the specialized control system carries on the monitoring, and opens its correspondence agreement to the construction equipment supervisory system, achieved the interconnection between the system and exchanges. For example the building electric power automatic monitoring system, uses the field bus technology realization data acquisition and processing, the centralism carries on the monitoring, achieved to changes the electrical power distribution system the telemetering, , the remote control and the remote letter, the realization changes the substation nobody value to defend. The system can unceasingly carry on gathering and the analysis, produces the essential prompt or the warning ahead of time, is advantageous for the system safe operation. The electric power automatic monitoring system uses the computer technology, the data processing technology, the control technology, the technology, the correspondence network technology, the electric power electronic technology and so on, but basically substitutes for traditional the secondary circuit, has the wiring simply, the performance reliable, is easy to maintain and so on the merit. At the same time, second consumes energy the big household lighting system energy conservation control to the building in also to start generally to take, the specialized illumination control system is widely applied in many buildings. The illumination control mode by the sole time cut-out control to the real-time induction control, reduces aspect and so on light control develops. In addition, the scene control, the remote control control, the scene control and so on the many kinds of nimble control mode, while maximum limit realizes energy </P>

conservation, but also has realized the lighting system comfortableness, the function and the human nature. For example at the end of 80's establishments "Architectural design Fire protection Standard" GBJl6 □87; 90's "Civil construction Illumination Design Standard" GBJl33 □90; "Civil construction Electricity Design Standard" JGJ/16 □92; "Industrial enterprise Illumination Design Standard" GB50034-92; "High level Civil construction Design Fire protection Standard" GB50045 □95; "Supplies Electrical power distribution system Design Standard" GB50052 □95; "l0kV And Following Transformer substation Design Standard" GB50053 □94; "Low pressure Power distribution Design Standard" GB50054 □95; "General Current collector Power distribution Design Standard" GB50055 □93; "Building Anti-radar Design Standard" GB50057 □94 and so on. In order to construct the electrical design to provide the basis which might follow, also moved towards the standardization for the construction electricity to step out to be solid step. The weak electricity aspect in at the end of 70's it mainly is the pronunciation correspondence telephone system and the simple broadcast amplifying system, enters to the 80's, along with altogether uses the televesion antenna, the fire auto-alarm system and the building equipment supervisory system application, the weak electricity system content are more and more many. Enters in particular to the 90's intermediate stages, the comprehensive wiring technology in the construction application, the weak electricity system design content gradually expanded from the initial several systems to several subsystems. "The intelligent construction" starts in our country to appear, in domestic has experienced the nearly 20 years development course, approximately may divide into two stages: The first stage is from the 80's last stages to the 90's intermediate stages, is tried to find out with the practice stage, this stage in intelligent aspect the and so on construction concept, design idea, construction standard understanding is also fuzzy; The second stage is in the 90's the last stage until now, for the large-scale construction and the high speed development phase, passes through the first stage nearly ten years practice application, in the profession and the society gradually tends to the intelligent construction understanding clearly, from the early time as the return rationality, is as blindly objective. If corresponds the construction intellectualization technology and its the application have also obtained the considerable development, the related intelligent construction supposes the juice, the construction, the approval standard and the correlation laws and regulations gradually obtains the establishment and is perfect. To the 90's last stages, the domestic intelligent construction construction oneself gradually steps onto the health, has the foreword the development track. Enters for the 21st century, along with the social information development, the construction intellectualization system oneself becomes in many buildings the essential infrastructure, the intelligent construction design, the system integration business troop unceasingly expands, has developed into in a construction profession emerging force, if the necessary product manufacture profession also and the industry direction develops to the domestic product, and has entrusted with the building brand-new concept. Since January, 1996 construction department held the national first intelligence construction seminar in <st1:City w:st="on"><st1:place w:st="on">Shanghai</st1:place></st1:City>, our country intelligent construction has obtained a bigger development. This conference from the intelligent construction definition, the concept, the construction standard when the construction intellectualization system technical application has formed a more objective understanding, and proposed should the rational treatment intelligence construction construction and the development, to the intelligent construction technology promotion and the application the positive function. The intelligent construction gradually expands from the initial real estate business development commercial construction to the government office building, the guesthouse, the commercial building, the hospital, the bank, the negotiable securities, the library, the museum, the exhibition center, the navigation station building and so on each kind of public building, and gradually to residential district development. In order to strengthen to the construction intellectualization project design management, the standard engineering design, the guarantee engineering design quality, in 1997 and in 1998, the construction department has issued "Construction Intellectualization Systems engineering Design Management Temporary provisions" and "Intelligence Architectural design And System integration Intelligence Management Stipulation". 1998 year's end, the construction department have promulgated the 194th document, namely "and do the experiment site work about the establishment construction intellectualization systems engineering design and the system integration special intelligence the notice", as well as about construction intellectualization systems engineering design and system integration business intelligence standard appendix, this is the market accurate person qualifications which designs regarding the participation intellectualization and contracts, has caused the enormous echo in the construction intellectualization profession. Until now, is allowed to enter this market the design and system integration business has reached more than 1,000. In order to assist to construct the profession government department to carry on the corresponding management and the technical support, in under the construction department design department's leadership, in June, 1998 established the first session of building intellectualization systems engineering to design the expert board. In January, 2003, carries on the expert board the reorganization, personally was responsible by a construction department leader, to establish the construction department architectural engineering technical expert committee, the construction intellectualization technical expert committee has taken a committee. The expert board took government consultant and the assistant, assist the government to carry on the profession management and the technical service, develops demonstration project and experiment site project aspect the and so on technical consultation work, leads the decision-making for the correlation department to provide the basis. Emerges along with the intelligent construction in <st1:place w:st="on"><st1:country-region w:st="on">China</st1:country-region></st1:place>. Urgent needs to have the correlation the regulations, the standard and the standard takes the design and the construction instruction technology laws and regulations. In March, 1995, the Chinese project constructed the standardized association communication engineering committee not to promulgate "Construction And Architectural complex Synthesis Wiring System design Standard". In July, 1995, <st1:City w:st="on">Shanghai</st1:City> has established our country first this locality intelligence architectural design standard by the <st1:place w:st="on">East China</st1:place> architectural design research institute. Afterwards, national many provinces and cities one after another have also established respective intelligence architectural design standard. In, 2000 the construction department has July promulgated GB/T50314 □2,000 "Intelligence Architectural design Standard". In February, 2000, by information industries department chief editor, construction department authorization GB/T50311 □2,000 "Construction And Architectural complex Synthesis Wiring Systems engineering Design Standard" and GB/T50312 □2,000 "Construction And Architectural complex Synthesis Wiring Systems engineering Approval Standard" officially promulgates. These technical laws and regulations formulations, had the foreword for our country intelligence construction health the development to lay the technology base. In August, 2000, the construction department revision has issued "Building Anti-radar Design Standard", increased in the intelligent building weak electricity system the massive electronic products anti-radar to strike and to prevent with emphasis the thunder and lightning pulse destroyed provision. In 2004 has promulgated "Information system Anti-radar Design Standard" C-B50343 □2,004. In order to can well and the design standard links up, achieves, the objective appraisal fairly to the project quality, provided the basis for the intelligence architectural engineering quality approval, the construction department has July promulgated GB/T<st1:chmetcnv w:st="on" UnitName="in" SourceValue="50339" HasSpace="True" Negative="False" NumberType="1" TCSC="0">50339 in</st1:chmetcnv>, 2003 □2,003 "Intelligence Architectural engineering Quality Approval Standard". Thus basically reached higher authorities from the design, to construct to approves each important link to have a legal basis. The intellectualized technology is only one method, is through to the construction intelligence function equipment, emphasized the high efficiency, the low energy consumption, the low pollution, in truly realize under the humanist premise, the realization saves the energy, promotes the building use function, to protect the environment and the sustainable development goal. The construction implementation, needs highly to embark from the sustainable development strategy, the attenion ecology, the attenion environmental protection, is the sustainable development eternal subject. Through many years practice, by the rationality and the practical manner, embarks from the project actual need, take practical and is suitable as the standard, not blindly with wind, one-sided pursue intellectualization system  and comprehensive, but is by is moderate in the technology in advance, also achieves the investment reasonable design idea, in view of different aspect the and so on project use function, investment standard and management request special details, discovers , the reliability, the rationality and the efficient most superior point of intersection, this idea at present the oneself becomes the intelligent construction profession the mutual recognition. Construction intellectualization technology development, also caused the national each construction universities to aim at this technology to open the corresponding specialized curriculum in abundance, and trained the correlation specialized graduate student. Until now the nation had several thousand intelligent constructions to complete one after another, focuses attention on the world construction zone, simultaneously the nation residential district intellectualization system demonstration project also one after another completes. After the construction department science and technology development promotion center appraised passed one batch actual to use, to have the domestic leading level in the project the construction intellectualization technology technical achievement. The construction intellectualization technology is multi-disciplinary, the cross profession systems engineering. The construction intellectualization technology mainly includes: Constructs the equipment automatic monitoring to be systematic, the safe guard system, the parking lot management system management system, fire auto-alarm and the fire prevention interlock system, the correspondence and the computer network system, the synthesis wiring system, the broadcast system, the wired television system, the digital conference and the video frequency conference system, the system integration and so on several subsystems. The domestic construction intellectualization technology has developed at first from the independent various subsystems to the system integration. (1) construction equipment monitoring technology 1980s mainly use the computer centralism monitoring the way, because reliability worse, the running rate is slower, the 90's later already very little will use, displace were the collection type control modes. In at the end of the 90's, along with the computer technology, the control technology, the network and the communication development and the union, constructed the equipment monitoring technology to obtain the rapid development, prominently displayed in: 1. field buses system structure and the reference model, the application software development platform and the tool, the field bus application and so on various aspects obtained the very big development, the field bus technology obtained the widespread application in the construction equipment supervisory system. 2. in to controls aspect and so on network network technology, real-time network operating system, reliable technology conducts the thorough research under the premise, appeared the ether control network. 3. controls networks and an information network integrated into control network technological development hot spot, each kind of building equipment supervisory system and the information network integrated technology is day by day mature. 4. each kind of control network new technology obtains the application in the construction equipment supervisory system. The computer domain OPC technology, the Web technology, TCP/IP gradually fused in the construction equipment supervisory system, greatly impelled the construction

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left; mso-pagination: widow-orphan" align=left>equipment monitoring technology development. (2) safe guard technology safe guard including the closed circuit television monitoring, the invasion reports to the police, the channel control , patrols, to speaks, the border guards against the small steelyard system. Peacefully guards against the system to be mutually independent from the initial various subsystems, between the development until now various subsystems linkage, enormously enhanced the safe guard hermeticness, the reliability and timeliness, for people's work, the study and the life has provided the safety control. The closed circuit television monitoring subsystem also develops from the former simulation technology to the digitized direction, the entire security guard system also faces the system scale, the digitization, the integrated direction is developing. In (3) correspondence network technology intelligence construction correspondence network including the computer network, the bidirectional cable TV transmission network and the telephone communication network and so on, first two has concentrated the nearly complete information application and the information management resources as the intelligent construction wide band backbone net, has connected the nearly complete user stand. Before 1990s intermediate stages, each kind of type network has the certain market and the user, but in the 90's later periods, the ethernet by its investment reasonable, the wiring nimble, the performance is superior, merit and so on use maintenance convenience, gradually leads the field in each kind of network communication. The ethernet transmission speed, from initial 10Mbps, 100Mbps has developed to 1Gbps, a 10Gbps even higher speed. The intelligent construction telephone network (including ISDN, xI) □SL), at present besides uses in the pronunciation correspondence, but also may have both the data, the picture and so on the narrow band data communication, enables the people to be allowed through the correspondence network, realizes function and so on TV conference, teleconference. Turns on the net technology is the intelligent construction with exterior network connection key, it causes the visible world to change more and more young, caused people's work, the life to have the very big change. The intelligent construction meets the person city territory net or Internet, the request meets person's band width to be more and more high, satisfies the user data communication daily aggregate demand. While wired network development, the wireless network to it meets person's flexibility, starts to enter the fast development phase. From initial <st1:chmetcnv w:st="on" UnitName="m" SourceValue="11" HasSpace="False" Negative="False" NumberType="1" TCSC="0">11M</st1:chmetcnv> to 2003 through <st1:chmetcnv w:st="on" UnitName="m" SourceValue="54" HasSpace="False" Negative="False" NumberType="1" TCSC="0">54M</st1:chmetcnv>, now develops to 100000000000000 above, it accessed the net for people's migration has provided the enormous convenience, simultaneously was containing the huge development potential in many domains, was becoming the network development the tidal current. (4) synthesis wiring technology synthesis wiring is in the intelligent construction the data, the pronunciation as well as the multimedia correspondence foundation platform, has entered our country market since this technology, as a result of its outstanding performance, has brought one new idea, the new technology for the domestic intelligence construction market, and has caused the giant echo immediately in the construction profession, by each kind of intelligent construction widespread use. In order to adapt the network transport tape affable speed development, the comprehensive wiring new product is published one after another, from initial 3 kind of lines, 5 kind of lines to 6 kind of lines, even appeared in advance in the standard 7 kind of wiring systems product, satisfies 1000000000000000 nets the demands. Along with the network transmission speed promotion, for adapts its development 10000000000000000 optical fibers network also to invest the market, the new multi- molds and the single model optical fiber took the good transmission medium obtains the widespread application. Copper cable from three kinds to five kind, ultra five kinds of, six kind of even higher categories, develops from the copper cable to the optical cable, the technology and the product unceasingly renews, fully manifested 汀 the development to be rapid as well as the intelligent construction applies new technical the broad prospect. (5) system integration technology in intelligent construction each subsystem, generally speaking connects by respective network, stands in respective operation completes the anticipated work, but not yet achieves information resource sharing. In order to achieve the management the convenience is quick, between various subsystems information resource sharing, should carry on the system integration. In the system integration process, integrates the system platform which chooses differently, network architecture different, integrates the subsystem scope is different, has the different integrated pattern. Along with the computer technology, the network technology, the control technology, the demonstration technology development, causes the building equipment supervisory system to be connected through the computer network with other subsystems, from this produces constructs the equipment supervisory system primarily system integration way. Also has by respective system equality carries on integrated the way, establishes the system integration management network, regards as various subsystems the lower level scene control network and by the equal way integration. Various subsystems real-time data, through the open industry standard connection, transform the unification the form to save in the system integration database or the server, system integration management network through procedure to various subsystems realization unification management, monitoring and exchange of information. The system integration, uses the open agreement to achieve between each correlation subsystem the linkage control and information sharing, enhanced the management efficiency, also enhanced processing arise suddenly the event the ability, and had achieved conserved energy and saves the manpower the goal, this was constructs the equipment management system management system (BMS). The system integration is not a goal, but is promotes the building use function and the enhancement management efficiency technical method, the integrated content is not many benefits friendly, but should according to use with the management need, in the technology mature, the system reliable, the investment reasonable, the management is highly effective and so on under the premise, according to must integrate. (6) residential district intellectualization 1990s the international intelligent housing and the electronic room idea influence, the construction intellectualization technology gradually extend to the residential district, at first obtain the result in an our country coast minority economy more developed city. The construction intellectualization technology starts from the public building to the housing and the housing plot development, the construction intellectualization technology rapidly extends to the plot intellectualization, the oneself becomes the intelligent construction development the important market. From public building intellectualization to housing intellectualization, this is the market demand, also is the actual need to develop. Each place design institute put the housing intellectualization the important position, the housing has provided to the intellectualization the platform, but the intellectualization also was in the housing design has the front and the challenge domain. The residential district intellectualization technology development may induce into following several aspects: The system design emphasized the humanist design idea, should give dual attention to the convenience which various levels inhabitant uses, and processes the good security and the comfortable relations, and the usable relations, the function disposition and the reasonable investment relations. The safe guard system from one each one is independent peacefully guards against the subsystem development for the family and the plot, the technique guards against the synthesis which unifies with the civil air defense peacefully to guard against the system. The information correspondence aspect may choose the way by the sole wide belt joint person way development for the multi- operations business, the wide band to turn on the network by xD □SL, the bidirectional cable TV network and so on to sets up the plot computer local area network direction to develop, the plot inhabitant may enjoy the information correspondence service meets the person from sole wide band Internet to serve the diverse increment service extends to the plot local area network on. The electromechanical device automatic monitoring, the water and electricity gas meter far makes private copies delivers, the sound video frequency system, the system and so on the estate management information application, caused the plot inhabitant's living conditions and the quality of life obtained the enormous enhancement. Lives at home the intellectualized technology application, caused the plot inhabitant really to experience the information time to bring for the life all sorts of convenient and is splendid, causes concept and so on family work, network life to become the reality. In order to guide our country intelligence residential district the health development, the construction department housing industry promotion center has December promulgated "Nation Residential district Intellectualization System Demonstration Engineering construction <st1:place w:st="on">Main</st1:place> point And Technology in, 1999 Leads Then" (implementation manuscript), to carried on the demonstration the project to make the detailed stipulation and the request. This regarding the standard residential district intellectualization market, impelled the residential district intellectualization construction health to have the foreword to develop the key function. In this foundation, carries on the housing intellectualization model area plan demonstration, with instructs the nation residential district intellectualization technology the health, to have the foreword development. The residential district intellectualization develops rapidly in our country each place, holds the suitable proportion in the every year nation cities housing development total quantity several hundred million square meters, and has gradually become the residential building development the mainstream. At in the nation residential district intellectualization system demonstration engineering construction foundation, the construction department housing industry promotion center has February issued "Housing Plot Intellectualization System Construction Main point And Technology in, 2003 Leads Then", takes the plot intellectualization design, the construction basis. This also indicated the housing intellectualization officially moved towards the comprehensive residential district intellectualization construction from the demonstration project. As a result of our country environment and the condition particularity, the intelligence residential district product forms a complete set with difficulty introduces, urges the domestic product supplier massively to develop each kind of product which the intelligence residential district needs, thus has formed the new intelligent construction industry. Because the wide band net enters the plot as well as the plot scale expansion, now also proposed the digital community's idea, pushed the intelligence residential district development to a new stage. The digital community further strengthened the network function, has the complete local area network and WAN, the internet wide belt joint person. May realize the community electromechanical device and the family electric appliance automation, the intellectualized monitoring through the complete network, peacefully guards against the system the automation, the intellectualized monitoring. The digital community application modern technology, the numerical information processing technology, the digital communication technology, the computer technology, the multimedia technology and the network technology, sped up the information dissemination speed, enhanced information gathering, the transmission, processing, the demonstration performance, strengthened the security. The digital community enhanced the intellectualized system integrated degree, has realized the information and resources full sharing, enhanced the system optimized degree. The digital community was the digital city unit pitch point, the digital community's construction has created the condition for the digital city, for the electronic government affairs, the electronic commerce, the electron flowed and so on the technical application has built the foundation. The intelligent construction in the our country construction profession rapid development, and improved people's living standard regarding the transformation promotion tradition building profession to get up the positive role. The intelligent construction product domestic product level gradually enhances, has broken the overseas product monopoly domestic market aspect through the market competition. After <st1:country-region w:st="on"><st1:place w:st="on">China</st1:place></st1:country-region> joins WTO, the construction market gradually becomes the foreign completely open market, how should to the construction intellectualization market competition, urgently have to cause the intelligent building industry to move towards the intensified development the path. The intensification may bring the huge economic efficiency for us, and greatly enhances the working efficiency. Therefore, it will be enhances our country construction intellectualization market competition strength the important measure. Our country national economy fast continues to develop, the comprehensive national strength enhancement, the city information construction advancement, will provide the powerful safeguard for the intelligent construction development, our country intelligent construction development has been also facing a broader prospect.<o:p></o:p></P>
