介绍了便携式辐射监测仪测量单元的设计思路和实现方法。该测量单元的设计基于ARM7平台，利用嵌入式C语言编程实现。其功能是通过ARM7平台，控制仪器内部的高速FPGA电路，对外部数据脉冲进行计数，同时将采集到的有效数据保存到仪器内部搭载的Flash存储器中，通过显示器读出数据，达到有效记录测量数据的目的。%The design and achieving method of measure module for portable radiation monitor was presented. The design of measure module was based on the ARM7 platform, and carried out by built-in C program.The function carried out by counting for data pulse outside based on controlling rapid FPGA circuit inside the instru-ment by ARM7 platform,and save the data available to Flash store inside the instrument.
