基于冷贮备冗余技术的故障自修复设计，可在γ辐射探头不断电的状态下检测并自动更换故障件，完成对故障的修复。同时对故障件的名称、位置等信息建档并显示在系统计算机上。论文介绍了γ辐射探头的设计、几种故障自修复电路的构成及故障检测与自修复原理。%The fault self-recovery design based on the technology of cold standby redundancy can make the γradiation detector automatically detect and replace the failure pieces in uninterruptible power supply status.At the same time, the failure pieces’ information, such as name and position etc., can be show on the system computer.This paper introduces the design of the γradiation detector, some fault self-recovery electric cir-cuits, fault detection and self-recovery principle.
