A kind of submarine landslide monitoring device and monitoring 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 changes in seabed formations by a host computer, belonging to the technical field of seabed observation, and in particular to a device and method for monitoring seabed landslides based on MEMS sensors. Background technique [0002] Submarine landslides are unconsolidated soft sediments or rocks with weak structural surfaces on submarine slopes that slide along the weak structural surfaces of the slope under the action of gravity, which is a type of marine disaster. The reasons for submarine landslides, on the one hand, are due to the internal structure and dynamic conditions of the sediment, such as the content of clay in the submarine sediment, the high pressure generated by natural gas, etc.; on the other hand, some external triggers, such as earthquakes, waves, etc. Wait. In addition to directly endangering drilling platforms, submarine optical cables, submarine pip...
