Research and design new of wireless multi-component seismic advanced detection system in mine

摘要

In view of the current shortage of mine leading seismic observation system, such as unable to connect to the existing network, instrument concentrated heavy, large power consumption, the arrangement of cable of long and heavy, cumbersome sensor installation, not comprehensive analysis of access gas warning software, this paper designed a new type of mine wireless multi channel three component distributed leading seismic observation system. Through the system development, developed wireless data processing host, wireless AP router relay, wireless data acquisition terminal, three component pressure sensor, the synchronizer; the realization of down hole data acquisition terminal of wireless ad hoc network, seismic data wireless transmission processing, synchronous acquisition and storage distributed holes and high precision data, three component pressure hole type detection and early warning of gas comprehensive analysis software interface. At the same time of observation system acquisition signal amplitude phase consistency and static experiments and in Gansu Jingyuan Coal Limited by Share Ltd Dashuitou Coal Mine in western mining area of the industrial experiment in the laboratory. The experiment and test results show that the precision of model, observation system, good stability, high amplitude and phase consistency, low background noise; portable low power consumption, the function is perfect, can meet the needs of field detection.
