室内定位终端的状态检测系统设计

Design of State Detection System for Indoor Positioning Terminal

针对室内人员物资定位终端独立分散、不能远程传输等缺陷,采用移动端和定位终端通过蓝牙(BLE)传输协议,对定位终端进行自身状态的检测。室内定位终端主要应用在大型商场、医院、车站等场景,用于室内人员和重要物资的定位。检测系统以APP形式运行在手机上,通过蓝牙传输自定义数据格式,上位机和下位机通过CRC校验进行数据安全验证。试验结果证明了该检测系统能够稳定运行在主流手机中,检测定位终端设备功能稳定。APP界面展示表明,该系统可以实时检测设备本身的状态。

For the indoor positioning terminal of personnel and materials features independent dispersion,cannot be transmitted remotely and other defects,using the mobile terminal and the positioning terminal to detect the status of the positioning terminal through the Bluetooth(BLE) transmission protocol.Indoor positioning terminal devices are mainly used in large shopping malls,hospitals,stations and other scenarios for the positioning of indoor personnel and important materials.The detection system runs on the mobile phone APP and transmits the customized data format through Bluetooth.The host computer and the device perform data security verification through CRC check.The experimental results show that the detection system can run stably in mainstream mobile phones,and the functions of detecting and positioning terminal equipment are stable.Through the display of the APP,the status of the device itself can be detected in real time.
