Low-power-consumption coal seam expansion deformation measurement host system and working method

The invention discloses a low-power-consumption coal seam expansion deformation measurement host system. A power supply is connected with a main control module, a sensor module, a display module and a storage module through a power protection module; the input end of the main control module is connected with the sensor module; the output end is connected with the sensor module after passing through the sensor power supply control module, and is also respectively connected with the display module and the storage module; the sensor power supply control module can control on-off of the sensor module. The invention further discloses a working method adopting the host system, the power supply supplies power to equipment, the sensor module is used for measuring the deformation amount of the coal seam, the sensor power supply control module can control starting and stopping of the sensor, and the sensor can be controlled to be closed when not working. Compared with the prior art, under the condition that the power s
