Abstract: 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.
