A Cable Type Seabed Seismic Monitoring System

Abstract

The invention discloses a cable type submarine earthquake monitoring system which comprises a main subsystem and a plurality of secondary extended subsystems, wherein the main subsystem is formed by connecting two earthquake monitoring shore base stations on a shore with a plurality of primary submarine earthquake monitoring stations in series, and forms an energy and data aggregation connection network of the submarine earthquake monitoring system; each secondary extended subsystem consists of a primary submarine earthquake monitoring station and a plurality of secondary submarine earthquakemonitoring stations cascaded layer by layer; each primary submarine earthquake monitoring station is used for realizing acquisition of earthquake data, carrying out digital processing on the collecteddata, receiving data sent by the secondary submarine earthquake monitoring stations connected with the primary submarine earthquake monitoring station, summarizing all the data and sending the data to the earthquake monitoring shore base stations; and each secondary submarine earthquake monitoring station is used for realizing acquisition of the earthquake data, carrying out digital processing onthe collected data, receiving the data sent by other secondary submarine earthquake monitoring station connected with the secondary submarine earthquake monitoring station, summarizing all the data and sending the data to the previous submarine earthquake monitoring station through an extended submarine cable.

Description

technical field [0001] The invention relates to the technical field of marine seismic observation, in particular to a cable-type submarine seismic monitoring system. Background technique [0002] At present, my country has established a relatively complete long-term real-time earthquake monitoring system on land. After an earthquake event occurs within the monitoring range, continuous and complete seismic data can be obtained in real time, and a simulation model can be established based on this data to calculate the location of the earthquake. Provide a certain period of earthquake early warning function. But on the other hand, the northern part of the South my country Sea and Taiwan are located in the circum-Pacific seismic zone. Due to the lack of necessary marine earthquake and tsunami warning means, earthquakes cause a large number of casualties and property losses every year. Due to the high investment cost of marine equipment and the need for long-term stable investmen...

AI Technical Summary

Problems solved by technology

The invention realizes the real-time data transmission capability of the seabed seismograph by adding a hardware communication interface, but the seismograph is only a simple upgrade of the traditional seabed seismograph, and can only be used by connecting to the seabed observation network, and cannot independently carry out seismic acquisition and The seismic data is sent to the shore base station in real time. In addition, the location of the invention is limited by the existing network of the submarine observation network, and independent seismic monitoring cannot be performed in the area of ​​interest. It is not a complete submarine seismic monitoring solution.
