Seabed landslide monitoring device and method based on MEMS sensor

Abstract

The invention discloses a seabed landslide monitoring device and method based on an MEMS sensor, and belongs to the technical field of seabed monitoring. A monitoring unit consists of a plurality of monitoring subunits which are connected in series. The monitoring unit is placed in a protection cover. The monitoring unit enables a monitored signal to be transmitted to a processing unit. The processing unit enables the processed signal to be transmitted to a computer terminal. A power module supplies a working voltage to a data processor. The MEMS sensor is fixed in a long pipe through a damping piece. One end of the long pipe is connected with one end of a soft connection pipe. The power module is connected with the MEMS sensor, and supplies the working voltage to the MEMS sensor. The MEMS sensor is connected with a data input port of the data processor. The data processor enables the processed data to be transmitted to the computer terminal. The device and method can achieve the monitoring and data recording of the changes of multiple layers of a seabed, achieves the monitoring of a single point to a plurality of points so as to form a three-dimensional monitoring plane, provides visual data for the research of the changes of the stratum of the seabed, and provide information support for the early-warning services of the seabed landslide.

Description

Technical field [0001] The invention relates to a device for real-time monitoring and real-time display of submarine stratum changes by an upper computer, belonging to the technical field of submarine observation, and in particular to a submarine landslide monitoring device and a monitoring method based on a MEMS sensor. Background technique [0002] A submarine landslide is a phenomenon in which unconsolidated soft sediments or rocks with weak structural surfaces on the submarine slope slide along the weak structural surfaces in the slope under the action of gravity, which is a kind of marine disaster. The reason for the occurrence of submarine landslides is, on the one hand, the internal structure and dynamic conditions of the sediments, such as the high content of clay in the seabed sediments and the high pressure generated by natural gas; on the other hand, it is caused by some external triggers, such as earthquakes and waves. Wait. In addition to submarine landslides direct...
