Abstract：Aiming at the large amount of electromagnetic interference in underground coal mining, and the sudden, and continuity feature of electromagnetic radiation signals produced in the coal mine field and loading coal and rock burst in coal and rock dynamic disasters, this paper developed a new type of coal and rock electromagnetic radiation real-time monitoring device. High performance DSP processor TMS320LF2812 and programmable gate array FPGA were used to build real-time monitoring system. The design of the peripheral circuit was carried out and the final test was performed. Results of testing show that the system is capable of loading coal rock electromagnetic radiation signals effectively remove interference, accurate extraction of electromagnetic radiation signals, and can acquisition, storage, and process of the continuous waveform, which can provide the basis for accurately obtaining the electromagnetic radiation precursor information.
