Isolate signal and power through the device at measurement system's collection system under water end, utilize a coaxial cable to realize supply voltage and difference signal transmission under water, not only solved the problem of interference, also simplified the experiment complexity.
Description
Technical field
The present utility model belongs to submarine radiated noise technical field of measurement and test, relates to the coupling device of the differential signal of underwater power power supply and collection data in the digital transmission technology in a kind of underwater measurement system.
Background technology
The data transmission of the boats and ships underwater noise measurement system that China is presently used is main uses analogue transmission technology, there is more drawback.Along with development and the raising of the level of measurement of technology, this method is the most increasingly not suitable with the large capacity data acquisition of underwater measurement devices and the needs of transmission.Digital communication technology is utilized to can effectively solve the problem that the problem that analogue technique causes.Owing to digital measuring system needs underwater operation power supply, this also will become the latency of signal disturbing；The convenience laying and reclaiming when simultaneously taking account of the actual measurement of measurement system sea.It is badly in need of a kind of simplicity, practical applicable sea faring measurement apparatus.
Utility model content
The purpose of the present utility model is to provide for the coupling device of the data signal (differential signal) of a DC source and transmission, then utilizes coaxial cable to realize the transmission that the underwater units in measurement system is powered and gathered data.
The technical solution used in the present invention is:
A kind of direct current carrier device for underwater measurement system, this direct current carrier device includes direct current loading end, coaxial cable interface, coupled inverters, signal loading end；It is that underwater operation device is powered that direct current loading end adds DC voltage, and when the most waterborne, underwater portion communicates, differential signal is inputted by signal loading end, and coupled changer is loaded into coaxial cable；Power supply and signal are coupled transmission by coaxial cable, realize the communication of test vessel and harvester under water through coaxial cable；Described direct current loading end is a multiple filter, the wave filter being made up of electrochemical capacitor, ceramic disc capacitor, inductance.Described signal loading end and coupled inverters are a wave filter and a transformator, and wave filter is the wave filter being made up of electric capacity and resistance；Under immunization with gD DNA vaccine, transformator is a kind of transformator meeting limit, source and secondary inductance value ratio about 3.5:1.
Signal and power supply are separated by the end of harvester under water in the system of measurement through this device；When the data collected upwards are transmitted, then at test vessel end, data and power supply are separated.So by half-duplex operation form complete test vessel and acquisition system under water communicate and data are transmitted.
Of the present utility model provide the benefit that: avoiding analogue communication and the drawback of ordinary numbers transmission technology by the application of this invention, first solve the interference problem of power supply and signal, next achieves the high speed of 485 buses, Long-range Data Transmission；3rd is marine traverse measuring device due to this system, therefore measurement apparatus to lay and reclaim also be the difficult point of experiment.The application of this invention also greatly simplified laying and reclaiming of system, reduces the difficulty of test and improves the accuracy of test.
