电子雷管延时精度测试仪的设计

Design of Electronic Detonator Delay Accuracy Tester

电子雷管延时精度测试仪是为了测试电子雷管延时精度而设计的专用测量仪器。该设计采用高灵敏度的微音传感器接收电子雷管起爆声音信号，经过高速16位单片机dsPIC30F4013中断处理后，测试出电子雷管起爆延时，通过与设定起爆延时对比后得出起爆延时精度，并且对测试仪进行了大量的试验，测试结果满足了设计和使用要求。

This paper introduces a electronic detonator delay accuracy tester which is a special measurement in- strument. The tester receives sound signal of electronic detonator detonation by a high sensitivity micro-phonic sensor. After the interrupt processing of 16-bit high-speed micro-controller dsPIC30F4013,the tester can get the delay accuracy of electronic detonator detonation by comparing the set detonation delay. The testing results meet the requirejments of design and application.
