摘要
本文在分析电火工品可靠性试验影响试验可靠性的各种因素、尤其是人为因素和环境因素的基础上 ,根据国军标要求和电磁学原理 ,提出了一种非接触式的电火工品可靠性试验无损耗监测系统方案。该方案基于电磁学中的霍尔效应 (HallEffect)原理 ,采用磁平衡式电流传感器作为电信号传感器 ,使用高速模数转换芯片或转换卡将采到的信号转换为数字信号存入随机存取存储器 (RAM )中以供处理。可以预见该种监测仪器的研制将在电火工品可靠性试验中将起到减少人为失误、提高试验成功率等重要作用 ,对改善电火工品发火可靠性试验工作具有重要意义。
A monitoring system scheme for non-contact, lossless reliability test of electric explosive device (EED) was proposed based on an analysis of all kinds of factors affecting EED reliability test especially the artificial and environmental factors. The scheme is based on the Hall effect principle of electromagnetics, using magnet-balanced current sensor as an electronic signal sensor, applying high spped A/D converter or converting board to transform the acquired signal into digital signals stored in random access memory for later processing. Development of the monitoring instrument can reduce human errors, increase ratios in test success, and improve tests on EED firing reliability.
