It includes a data acquisition device, which is used to collect the seismic wave signal in coal mines and reflect the possibility of the current coal and gas outburst hazard through the seismic wave signal described; a data processing device, which is used to process the collected data, eliminate the interferential signal and convert the effective signal into the measured physical quantity, and then send it to the display unit or save it; a real-time processor, which is used to achieve the acquisition and processing of real-time data; a display unit, which is used for the process of acquisition, storage, display and historical data query, and the display of residual capacity; a power supply unit, which is used to provide energy for the whole monitoring device.

Abstract: The invention declares a FBG (fiber Bragg grating) intelligent device and method for monitoring coal level in bunker. The device comprises a support device located above the bunker and detachably connected with a vibration device. The vibration device, with a surrounding reserved groove on its shell, extends into the bunker, and the groove is used for embedding FBG sensing device which is connected with FBG Network Demodulator. The Demodulator is electrically connected with a data processing system which is electrically connected with an alarm device, and the alarm device is connected with the belt conveyer. The invention relates to wavelength drifts of FGB, which has fast response and high precision, and can transmit signals to the display device first, providing good operating environment for the bunker.
