Embedded water depth measuring system with hydrophone comparison function

Abstract

The invention relates to an embedded water depth detecting system with a hydrophone comparison function, which is technically characterized by comprising a digital depth measuring plate, a depth measuring transducer, a selector switch, a hydrophone and a computer provided with data collecting and processing software. The digital depth measuring plate comprises a digital signal processor (DSP), a time sequence and logic control module connected with the DSP, an A / D (analog to digital) conversion module, a serial communication circuit and a USB (universal serial bus) communication circuit, wherein the time sequence and logic control module and the A / D conversion module are respectively connected with an emitting circuit and a receiving circuit, the emitting circuit is connected with a hydrophone by the depth measuring transducer, the depth measuring transducer and the hydrophone are connected to the receiving circuit by the selector switch, and the serial communication circuit and a USB communication circuit are respectively connected with the computer. The embedded water depth measuring system disclosed by the invention has advantages of reasonable design, high precision, reliable performance, convenience in use and the like; and moreover, the embedded water depth measuring system with the hydrophone comparison function can thoroughly replace a detection plate to carry out comparison depth detectors at a shallow water zone within 20m, and fill a vacancy that the conventional depth detector does not have the hydrophone comparison function.

Description

technical field [0001] The invention belongs to the technical field of marine measurement, in particular to an embedded water depth measurement system with a hydrophone comparison function. Background technique [0002] At present, in ocean bathymetry, depth sounders are often used for measurement. However, due to certain errors in the depth sounder equipment itself, the accuracy of the measurement data is affected. At present, there is no unified inspection mechanism and detection method for water depth sounders. Users need to use inspection boards to perform error comparison detection of depth sounders at the measurement site. However, using inspection boards for comparison is difficult and has low accuracy. Although domestic equipment using hydrophones for comparison appears, the corresponding equipment does not embed the function of hydrophone comparison into the water depth measurement system, and it is difficult to play a corresponding role.
