In the field of marine mapping technology, echo sounding has always been a powerful means of measuring water depth. Because it can measure the continuous data of water depth quickly and accurately while the ship is sailing, the echo sounder becomes the main instrument for water depth measurement. Widely used in navigation surveys, seabed topographic surveys, hydrographic surveys, navigation and positioning of vessels. It is known that the structure of the echo sounder is provided with a transducer array at the lower end of the hollow cylinder. The transducer array is connected to the transceiver switch through a cable, and the transceiver switch is respectively connected to the transmitting module and the receiving module to transmit. The output of the module and the receiving module is connected to the data signal processing module, and the data signal processing module is wired to the display terminal (display screen, keyboard) and the like. That is, the hollow cylinder and the transducer constitute a transducer tube, and the transceiving switch, the transmitting module, the receiving module, the data signal processing module, and the display and control terminal constitute a host, and the transducer tube is connected to the host through a cable. When measuring the depth, fix the transducer tube to the measuring vessel On the side, the transducer at the head is placed under water, The main unit is placed on the deck. The working principle is that the transmitting module transmits the acoustic pulse from the sea face downward through the transceiving switch, and the reflection occurs when the submarine medium with different density is encountered. The reflected acoustic pulse propagates upward in the seawater and is transmitted by the sea surface transducer. Receiving, the signal received by the transducer passes through the receiving module to the data signal processing module, and the data signal processing module calculates the linear distance of the transducer to the sea bottom according to the time when the acoustic pulse travels back and forth in the seawater and the speed of sound in the seawater. That is, the water depth is stored and displayed by the display terminal. The above-mentioned echo sounder has the following problems during actual use, especially when using a small fishing boat for immediate installation and disassembly:

(1) The cable connection method is not only troublesome to install, but also time-consuming and laborious, which increases the workload of the surveyor.

Moreover, the scope of the host is limited and the range of activities of the measuring personnel is limited, and the handling flexibility is poor;

( 2 The single display terminal integrated on the host can only be operated by one surveyor. It does not have the ability to post-process multiple sounding data synchronously. It can not realize real-time quality monitoring of the measurement process, which limits the optimization of the measurement process. And the improvement of efficiency, and sometimes even need to carry out retesting and retesting later;

(3) Dynamic draught automatic compensation cannot be realized.
