Abstract

The invention relates to an underwater detection sensor intermediary device, and the device comprises an overwater module, wherein the overwater module comprises an expansion unit and a first control unit, the expansion unit expands at least one serial port unit, and the serial port unit is electrically connected with the first control unit; an underwater module which comprises an isolation unit, a second control unit and at least one serial port bus transceiver, wherein the isolation unit is electrically connected with the first control unit through a first watertight cable, the second control unit is electrically connected to the isolation unit, and the serial port bus transceiver is electrically connected to the second control unit. According to the invention, the above-water module and the underwater module are separated, and the power supply and the communication are physically isolated, so that the technical problems of connection difficulty caused by sensor difference, power supply noise or poor sensor stability and reliability caused by overlarge coupling noise of complex electromagnetic environment water conditions in existing underwater detection are solved.

Description

technical field [0001] The invention belongs to the technical field of underwater detection, in particular to an underwater detection sensor intermediary device towed by a ship. Background technique [0002] Today's marine pollution is becoming more and more serious, and people's demand for marine environmental monitoring is becoming more and more urgent. Using ships to carry in-situ ecological sensors such as chlorophyll, backscattering, oil in water, and dissolved oxygen to monitor the marine water environment is a common method in marine pollution monitoring, but different combinations of sensors are required for different voyages or tasks. There are also various brands and models, and each sensor has its own operating software, which makes it difficult to connect and operate the sensors during sea trials. Moreover, the power supply on board is mostly powered by a modified sine wave inverter, and the high-frequency noise contained in the output signal will affect the pre...
