摘要
基岩磨损是造成海底电缆故障的主要原因之一。针对这一问题,研制了新型海底电缆监测系统。首先,提出长距离多节点同步采集方法,建立海底电缆的形状重构及定位模型;随后,开发了传感器、采集板、控制板、4G无线传输和电池模块;接着搭建了基于MEMS(微电子机械系统)传感阵列的海底电缆监测系统;最后,通过强磁环境试验、压力测试试验、传感阵列的精度试验及在朱家尖海底电缆登陆段的长期监测,验证了该监测系统可实现海缆的位移监测和监测数据远程实时传输。
Bedrock wear is statistically one of the major causes of submarine cable failure.Therefore,a new subma⁃rine cable monitoring system is developed.First,a long-distance multi-node synchronous acquisition method is pro⁃posed 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 moni⁃toring 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.
