Abstract

The invention relates to an array electrochemical feedback seismometer, and belongs to the seismological observation field. The array electrochemical feedback seismometer includes an electrochemical transduction array, a multi-flow-channel cavity, sensitive liquid, an elastic seal membrane, a circuit system and a feedback motor, wherein the electrochemical transduction array is formed by a plurality of electrochemical transduction units of a planar array; a plurality of flow channels corresponding to the electrochemical transduction array are arranged in the multi-flow-channel cavity; the circuit system includes a detection circuit, an operation circuit and a control circuit; and the feedback motor is connected with the output of the control circuit to perform force feedback control on the seismometer. The array electrochemical feedback seismometer can measure three mutually orthogonal single component translation and double component rotation seismic signals at the same time, and perform correction of rotation inclination angle on a translation signal.

Description

technical field [0001] The invention relates to the field of earthquake observation, in particular to an array type electrochemical feedback seismometer for natural earthquake observation. Background technique [0002] The electrochemical seismometer is a new type of seismic sensor developed in the last ten years. It uses liquid as an inertial mass body, and uses electrochemical electrodes to detect the movement information of the liquid in the flow channel to characterize the external earthquake. Compared with traditional solid-state inertial body seismometers, liquid inertial body seismometers not only have the advantages of large gain multiples, high sensitivity, and good low-frequency characteristics, but also have a large range of working inclination angles, sensitive devices are almost immune to electromagnetic interference, and have strong impact resistance. Features such as no mechanical noise, no need to unlock / lock the inertial pendulum during handling or use. [...
