摘　　要：介绍了事故总信号的重要性和适用范围,并结合事故总信号回路图,分析CZX-12R1型操作箱事故总信号形成逻辑以及存在的问题,介绍现有2种解决方案的局限性,提出一种去除脉冲展宽回路的方法,经验证此方法能简单有效的解决CZX-12R1事故总信号问题。This paper introduces the importance and scope of the general fault signal,then investigates the logic and the existing problems of CZX-12R1 operation box general fault signal by combing its circuit diagram. To solve the problems above,the paper analyzes the limitations of the two existing solutions and proposes a method of removing a pulse stretcher circuit,this method can solute CZX-12R1 general fault signal problem simply and effectively.
