Summary:Bedrock wear is statistically one of the major causes of submarine cable failure. Therefore， a new submarine cable monitoring system is developed. First， a long-distance multi-node synchronous acquisition method is proposed to establish a shape reconstruction and positioning model of the submarine cable. Then， sensors， acquisition boards， control boards， 4G wireless transmission and battery modules are developed， and a submarine cable monitoring system based on the MEMS （micro-electromechanical systems） sensor array is built. Finally， high-intensity magnetic environment test， pressure test， accuracy test of the sensor array， and long-term monitoring of submarine cables in the landing section in Zhujiajian prove that the system can monitor displacement of submarine cables and remotely transmit the monitoring data in real time.
