Background technique

Underwater detection instruments can detect and record the physical and chemical parameters of a specific water body area. In the past, a type of off-line (self-contained) detection instrument was widely used. After being put into the designated detection position, the instrument uses its own electric energy to work, collect target parameters, and store them in the internal storage area. After the set working cycle is over, the instrument is recovered and the detection data is read from it for analysis. However, because the deployment and recovery of instruments requires high costs and a lot of time, the data return cycle of offline (self-contained) instruments is very long. Although more accurate in-situ data can be obtained, the data lacks timeliness. The online underwater real-time detection instrument is an effective means to understand, master and study the operation rules of the seabed for long-term real-time physical and chemical parameter detection and transmission of the underwater environment, especially the deep sea environment. Compared with the above-mentioned offline (self-contained) detection instruments, real-time detection instruments can return the detection location information to the shore-based computer system in a timely manner on the basis of their in-situ detection capabilities, so that the data has a strong time-sensitive characteristics.

Underwater real-time detection equipment needs to be connected to the shore-based computer system through cables (optical cables, cables, etc.), and the power and control instructions from the shore-based system are obtained through the cables, and the detection data is returned through the cables. With the continuous expansion of the coverage area of modern ocean detection, the length of cables used to connect detection equipment and shore-based systems has greatly increased, and the layout of the sea area is vast. During the long period of operation, power failure due to unavoidable reasons is likely to cause damage to the underwater real-time detection system. The specific manifestations are as follows: 1) The device suddenly loses control, causing the mechanical system in the instrument to run out of control due to inertia. Collision between systems will cause mechanical damage; 2) Data collection will be interrupted, resulting in data loss.
