Embodiment 1

[0038] The third detection feedback circuit is used to monitor the temperature of the mine vibration sensor in real time, and to perform feedback control on the working voltage or current of the mine vibration sensor, and the third detection feedback circuit is connected with the temperature sensor. The third detection feedback circuit includes a field effect transistor Q3, a thermistor RT3, a resistor R3 and a control circuit. The control pole of the field effect transistor Q3 is connected to the resistor R3 and the thermistor RT3 respectively, and the drain of the field effect transistor Q3 is grounded. The source of the effect transistor Q3 is connected to the control circuit, the control electrode of the field effect transistor Q3 is connected to the common end of the resistor R3 and the thermistor RT3, the other end of the thermistor RT3 is grounded, and the other end of the resistor R3 is connected to the power supply V3. That is to set the thermistor RT3 near the detecte...
