摘要
近年来,环境辐射监测扮演了越来越重要的角色,目前使用的应急环境辐射监测装置通常基于数传电台进行远程通信,体积较大且受距离限制,因此设计了一款基于北斗通信的应急环境辐射监测装置,结合北斗卫星通信及定位技术、嵌入式技术、核辐射探测技术等实现实现了环境辐射在线监测.装置通过双G-M管探测器探测周围环境剂量率,通过北斗短报文通信模块将剂量率等信息发送给接收站.测试结果表明,该装置γ测量偏差在 7 个量程测试点都小于 7%,稳定性好,北斗卫星通信成功率不低于 80%,定位偏差小于 100 m,适合用于应急环境辐射监测.
Abstract
Combined with Beidou satellite communication and positioning technology,Embedded systems,nuclear radiation detection technology to achieve environmental radiation online monitoring.The device detects the dose rate of the surrounding environment through the dual G-M tube detector,then sends the dose rate information to the receiving station through the Beidou satellite communication module.The device operates stably and can well meet the needs of emergency environmental radiation monitoring.
