Abstract:

The paper introduced a design of the rockburst monitoring and warning system. Seismic data acquisition device uses MSP430F5438 as its CPU,which can effectively reduce the power consumption of system. We use the high precision microseismic probe, mount on the bolt and insert in rock mass, the output signal are converted by microchip’s A/D function into the digital signal with the help of high precision ADA4528 chip, the signal are transmitted to the signal receiving station through the Zigbee wireless devices,then transmitted to the ground hosts by optical fiber Ethernet . The host computer data processing software was written in VB2008, mainly realized the microseismic data collection and storage, real-time curve display and seismic tendency analysis, reports and print function.

Key words: rock burst disaster, microseism, prior-warning, Zigbee
