Acoustic seabed distance measurement system and method thereof

Abstract

The invention relates to an acoustic seabed distance measurement system. The system comprises an energy transducer, a pressure-resisting shell, an electronic cabin, watertight flanges, a watertight connector, a receiving emission module, a power supply management module, an on-duty circuit module, a work circuit module and a peripheral module. The electronic cabin is installed in the pressure-resisting shell. Two ends of an opening are installed with the watertight flanges. One watertight flange is connected to the energy transducer. The other watertight flange is connected to the watertight connector. The receiving emission module, the power supply management module, the on-duty circuit module, the work circuit module and the peripheral module are located in the electronic cabin. The energy transducer is used for carrying out conversion between an electric signal and an acoustical signal on the signal. The receiving emission module is used for receiving and emitting the signal. The power supply management module is used for managing a power supply. The on-duty circuit module is used for completing an on-duty task, cooperating with the power supply management module so as to complete a power supply management control task and transmitting a spreading distance of the measured acoustic signal between two points to a data recording device. The work circuit module is used for completing a real-time range finding task.

Description

technical field [0001] The invention relates to the field of seabed acoustic ranging, in particular to an acoustic seabed distance measuring system and method. Background technique [0002] The submarine acoustic ranging system uses acoustic ranging to measure the distance between multiple points on the seabed. Such as figure 1 As shown, the working principle of the submarine acoustic ranging system is: place a set of ranging systems on the submarine target points A and B respectively. According to the set parameters, the ranging system at point A periodically transmits ranging acoustic pulse signals, and the ranging system at point B After the ranging system receives the ranging acoustic pulse signal, it replies with a response acoustic pulse signal, and the ranging system at point A receives the responding acoustic pulse signal from the ranging system at point B, and calculates the transmission time τ of the acoustic signal between two points, Then according to the known...
