The seabed dynamic environmental monitoring system is an important subject of the ocean observatory testing system in the South China Sea. On the basis of the ocean observing network built during the "Eleventh Five-Year Plan" period, the stability and reliability of the system have been improved, with a series of subsystems designed and applied, including the CAN field bus communication, ARM dual redundancy backup, Modem acoustic gateway, DC/DC parallel redundancy and backup battery. It mainly carries the acoustic Doppler current profiler (ADCP), CTD developed by the National Ocean Technology Center and high-precision pressure sensors, and integrates the shore-based monitoring and feedback subsystem, control and data acquisition subsystem, and communication and power management subsystem, achieving long-term real-time stable monitoring on the bottom boundary velocity profile, turbulent velocity field, temperature, salinity, pressure and other ocean dynamic factors. Through experiments and testing, the system is proved both stable and reliable, and conducive to the expansion and integration of sensors, which provides a reliable verification and observation node for the seabed observing network.
