Zero-frequency micro-seismic acceleration sensor

The invention, which relates to the technical field of the sensor, discloses a zero-frequency micro-seismic acceleration sensor comprising a processing center which is electrically connected with a data acquisition unit, a data processing unit, a data analysis unit and an evaluation unit. Performance evaluation of the capacitor is completed by obtaining related parameters of the capacitor in the operation process of the acceleration sensor and combining the speed change condition of the sensor in the working environment, and when the performance evaluation result of the capacitor is abnormal, the performance of the capacitor is evaluated according to the state change and the current change condition of the capacitor. According to the method and the device, the reason causing the abnormal performance evaluation result of the capacitor is judged, so that the acceleration sensor can evaluate the self performance at any time in the use process, the acceleration sensor is prevented from continuously working in an
