为满足放射源安全管理中“位置锁定”的要求,设计出了针对GPS定位、振动报警、断电报警和位移报警的GPS放射源定位仪。定位仪通过SIM908模块GPS单元采集卫星定位信息,在MCU控制下,通过GSM网路完成定位信息、报警状态等短消息的上报。通过控制指令下发和报警状态数据上传测试,实验结果表明:GPS放射源定位仪可以有效地定位放射源位置,给出现场报警状态,满足工业现场放射源定位要求。
In order to meet the requirements of “Position Locking” in the safety management of radioactive sources, a GPS radioactive source locator is designed for GPS positioning, vibration alarm, power off alarm and displacement alarm. The locator collects the satellite positioning information through the GPS unit of SIM908 module and reports the short message such as positioning information and alarm status via the GSM network under the control of the MCU. The test results show that the GPS radio source locator can effectively locate the radioactive sources and give the status of on-site alarm to meet the requirements of radioactive sources localization in the industrial field.
