摘　　要：介绍了基于MCU的测氡仪的内部组成与实际电路原理。选用PHILIPS公司P89C58单片机作仪器的微控制器,实现了对输入脉冲的定时计数、数据处理、显示、键盘接口、通信等功能。仪器具有功耗较低、集成度与微机化程度较高等特点,适合用于野外工作。Introduction are given on the internal composition of the radon-detecting instrument based on MCU and the working of the real electric circuit. The single-chip microcomputer P89C58 of PHILIPS is adopted as the micro-controller of the instrument, realizing such functions as counting input pulses within fixed time, data processing, liquid crystal display, keyboard interface, serial communication, etc. The instrument turns out to be low in work consumption, with relatively high degree of concentration and computerization, and is recommended for field operations.
