Power is the heart of all electronic equipment as well as the key to ensure the normal operation of electronic equipment. However, there is no enough previous research on the power supply used in seismic stations. Based on the analysis of the existing problems of power supply in seismic stations, a general intelligent power controller is developed and designed in this paper. The control system is with microprocessor as core designed the corresponding signal acquisition, voltage control and drive circuit. The device has about 0.6 watts of power consumption and operating voltage range from 7 to 23 volts, and is capable of expanding and optimizing the original power supply system function of the station through external connection, which meets the design requirements of low power consumption, easy operation, and high reliability.
