The coal rock radiates electromagnetic signal outward during the process of force and rupture. By collecting and analyzing on this kind of electromagnetic radiation signals
it is possible to judge the degree of coal rock rupture in mine and evaluate whether there is a hidden danger of the landslide and realize the disaster warning. Aiming at the above scenarios
a high-speed data acquisition and data processing system is designed and implemented. Field programmable gate array( FPGA) is used as the acquisition part of the main controller to realize 12-channel high-speed synchronous sampling. The server-based processing software is developed to realize data diversification acquisition
real-time storage and real-time display
and the functions of signal recognition and radiation source localization algorithm implementation. The experimental results show that the system can achieve the predetermined function
and the operation is stable and reliable
which is of great significance for studying the characteristics of coal rock fracture radiation signal.
