摘要
近年来,中小学校园安全问题逐渐得到全社会的广泛重视,为了实时获取在校学生的位置信息,预防和避免危险的发生,设计了基于ZigBee技术以CC2530芯片为核心模块的学生室内定位系统,给出基于RSSI测距的定位算法流程、系统总体结构、节点硬件原理图以及软件设计方案;通过加入姿态传感器模块将定位数据融合,提高了定位精度。
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.
