摘要针对ESAD解除保险过程中，无法准确识别解保电源信号电压幅值的问题，提出了ESAD中解保电源信号识别优化方法。该方法采用“数字量+模拟量”的识别方法，其中光耦隔离电路作为数字量识别方式，AD采集电路作为模拟量识别方式， “数字量+模拟量”信号共同作为解保条件，以模拟量识别值作为起始判断门限，数字量信号进行有效判断，可提高ESAD的作用可靠性。验证试验表明，采用“数字量+模拟量”识别方法可有效识别解保电源信号且保证ESAD的作用可靠性，该方法具有可行性。

Abstract：In order to solve the problem that the voltage amplitude of the unsecured power signal cannot be accurately identified in the process of ESAD unsecured power signal, an optimization method for the unsecured power signal identification in ESAD is pro- posed. The method adopts the "digital + analog" recognition methods, using optical coupling isolation circuit as a way to identify digital quantity, AD sampling circuit as a way to identify analog quantity, "digital + analog" signal as the arming condition. By using analog recognition value as the threshold of initial judgment and digital signal to judge effectively, the reliability of ESAD function can be improved. The verification test shows that the identification method of "digital + analog" can effectively identify the signal and ensure the reliability of ESAD.

Key words： electronic safety and arming device arming power supply signal identification "digital + analog" recognition method operational reliability
