基于iMx6UL与时钟同步技术的微震监测系统设计

针对目前微震监测设备以普通单片机与非实时性应用系统带来的速度低、误差大等问题，设计了一款以高速ARM为处理器的高精度微震监测系统。该系统采用支持IEEE1588标准的高速处理器iMx6UL为主控MCU，选用Linux操作系统，结合24位AD采集芯片。实现了对磁电式振动传感器的高速数据采集、打印同步时间戳、数据网络传输，上层计算机进行震动定位计算。测试结果表明该系统数据测量精确，定位计算误差小，满足冲击地压矿井的使用。

Design of Microseismic Monitoring System Based on the iMx6UL and the Clock Synchronization Technology

Abstract: In view of low speed and large error caused by ordinary single-chip computer and non-real-time application system in microseismic monitoring equipment at present，a high-precision microseismic monitoring system was designed with high-speed ARM processor. The major MCU of the system is iMx6UL, a high-speed processor supporting IEEE1588 standard, with Linux Operating System and 24-bit AD acquisition chip. Through this system, high-speed data acquisition of magnetoelectric vibration sensor, synchronous time stamp printing and data network transmission are realized, and vibration location calculation is carried out by the upper computer.The test results show that the system has accurate data measurement and small positioning calculation error, which can meet the needs of rock burst mine.
