    Abstract：In recent years,the security of primary and secondary schools has gradually received the wide attention of the whole society. To obtain the location information of students in real time and prevent and avoid risks,a student indoor positioning system is designed based on ZigBee technology,with the CC2530 chip as the core module. The positioning algorithm flow based on RSSI ranging,the overall structure of the system,the schematic diagram for node hardware and the software design scheme are given. The positioning accuracy is improved by adding the attitude sensor module to fuse the positioning data.
