摘　　要：提出了一种γ射线环境剂量指示仪的研制方法,其特点是以AT89C52为核心,改进倍频接收电路,把具有I^2C总线功能的24系列E^2PROM和RS232串口等原件作为外围电路的设计思想,该设计原理可确保系统具有抗外界干扰性和测量准确优点,在实际应用中γ射线环境荆量指示仪可进行环境剂量的连续监测及与计算机通讯．The method and designing mechanism of manufacturing the monitor system for detecting the γ-ray radiation dose in environment are described. The characteristics based on mechanism designing of including AT89C52 as the core of system, improving multi-frequency receiving circuit and employing both the pieces of E^2PROM twenty-four series with I^2C total line function and RS232 string served as out-circle circuit. This improvement guaranteed the monitor system with the merits of advanced resistant capacity to outside interference and detecting accuracy. This method ensures that monitor system with continuing and instant response to the radiation dose in environment and having the reliable conversation capacity with computer in its practical application.
