摘要
为了解决煤矿微震监测孔中检波器问题,研制了一种使用电磁式超级动圈检波器的自动推靠孔中检波器,该检波器使用H电桥控制检波器推靠和回收,能自动监测工作电流,电流过大自动断电保护,使孔中检波器工作稳定可靠。通过性能对比测试,证明该孔中检波器性能良好,满足了微震监测系统孔中监测的需求。
In order to solve the problem of coal mine microseismic monitoring hole geophone, A geophone of using electromagnetic super moving coil device automatically pushed against the hole is designed. The geophone using the H-bridge control device to push against and recovery. It can automatically monitor the working current for automatic power protection when the current is too large, Let the hole geophone stable and reliable. Through performance testing, proved the good performance of the geophone and demand of microseismic monitoring in hole.
