基于GPS/GSM的放射源跟踪定位系统设计

The Design of Radio Source Tracking System Based on the GPS/GSM

基于GPS/GSM的放射源跟踪定位系统,主要由RFID无线射频识别模块、GPS无线定位模块和GSM无线传输模块组成。监控中心会定时向放射源发送确认信息,同时会由放射源向监控中心回复确认信息,从而确认放射源是否在安全范围内。当放射源被以某种方式移动后,监控中心得不到确认信息,启动报警装置,同时置于放射源上的GPS/GSM模块开始工作。GPS将定位信息由单片机处理后发送到GSM,然后由GSM发送到预定的手机终端。

The design of radio source tracking system based on the GPS/ GSM is mainly composed by RFID Radio Transceiver, GPS Unit and GMS Module. The monitor center would send a confirm message to the radio source timely. At the same time, another confirm information will be sent to monitor center from radio source, so that the radio source will be found in previous position. If the radio source were found somehow moved illegally, and the monitory center could not detect or accept the message from radio source, the warning system will be startup as well as the locating unit on the radio source. The GPS Unit would be on charge getting the information form the satellite and send it to the GSM Module via MCU. And then, the GSM Module would send the message to chosen phone.
