The invention discloses a wireless transmission system of micro-seismic monitoring data. The wireless transmission system comprises a micro-seismic signal acquisition processing unit, a field service unit, a computer room server, a data analytic center and an analytic decision-making client, wherein the micro-seismic signal acquisition processing unit is used for acquiring micro-seismic signals and converting the signals into digital signals; the field service unit is used for simply processing the converted digital signals and transmitting the processed digital signals to the remote data analytic center and the analytic decision-making client; the computer room server is used for receiving the digital signals; the data analytic center is used for analyzing the received digital signals; the analytic decision-making client is used for analyzing the signals, making decisions and performing remote control. The wireless transmission system converts the micro-seismic signals acquired by the micro-seismic signal acquisition processing unit to the digital signals, transmits the digital signals to the remote data analytic center and the analytic decision-making client through a GPRS (General Packet Radio Service), so as to implement in-time management and analysis of micro-seismic monitoring for geological disasters. The wireless transmission system is high in reliability, strong in instantaneity, wide in monitoring range, strong in expansion and low in cost, and greatly improves the working efficiency of analysis, processing and early warning of the micro-seismic information.
