The invention provides a seismometer self-adaptive leveling method and device and a seismometer. The seismometer comprises a leveling mechanism used for adjusting the position of a pendulum body, theleveling mechanism comprises a leveling assembly and a leveling driving unit, and the device comprises: a zero position detection circuit used for detecting the position signal of the pendulum body; an analog-to-digital conversion unit used for converting the position signal into a digital position signal; a processing unit used for determining a control signal according to the digital position signal; and a logic control unit used for transmitting the control signal to the leveling driving unit, so that the leveling driving unit controls the leveling assembly to execute a leveling action according to the control signal. According to the invention, automatic and self-adaptive leveling of the seismometer can be realized, the leveling precision is high, and the detection precision of the seismometer is ensured. 本发明提
