摘　　要：为了在大范围内对核设施周围环境进行辐射探测,设计了基于GPS的γ射线车载巡测系统,该系统由γ射线探测终端和PC上位机两部分组成。γ射线探测终端采用控制器ATmega128L作为控制核心,利用G—M计数管探测γ射线的辐射强度,通过GPS模块LR9845s获取位置信息,将辐射强度和地理位置信息结合起来按照约定的协议打包成数据帧,并通过串口发送至上位机;上位机对接收到的数据进行处理、显示和分析,同时存入Access2003数据库备份,还能结合GIS在地图上描绘出测量轨迹和辐射强度分布图。该系统可搭载在各种车辆上进行移动巡测,用于寻找放射源、应急监测、环境辐射水平测量等领域。In order to detecte the radiation in the surrounding environment of Nuclear facilities in a wide range, the γ - Ray vehicle patrol system based radiation on GPS and composed of 3＇ - Ray detection terminal and PC is designed. The γ- Ray detection terminal uses controller ATmega128L as control core, detecting the radiation intensity of γ - Ray with G - M counter tube and getting the location with GPS module LR9548S, packing a data frame with γ -Ray radiation and location information according to the agreed protocol which will be sent to PC throug UART interface; The PC can processes, display and analyze the data, baekuping to database Ac- cess2003, also can paint the measuring track and distributed picture of radiation intensity. The system can be equipped with a variety of vehicles for mobile patrol to use in the fields of searching radioactive sources, emergency monitoring and measurement of environmental radiation levels.
