Description
Technical field
The utility model relates to and utilizes ultrasound wave to weld the device of range finding under water.
Background technology
Along with oceanographic engineering is drive on boldly to the deep-sea, the complicacy of welding surroundings and danger under water, and the restriction of human physiological condition (depth capacity of saturated gas diving has only 650m), Automation of Welding has crucial meaning under the developing water.
Well behaved sensor is the prerequisite that realizes robotization; The soldered sensor of developing under water has under water, and EDDY CURRENT (UWET), underwater ultrasound imaging, eddy current method (ECI), interchange stress detect (ACSM), flash spotting (Photogrametry) etc.; But, become the difficult point of research at present because underwater operation is faced with problems such as electric insulation, hydraulic pressure, signal transmission.And there is the problem of poor anti jamming capability in existing undersea ranging device.
The utility model content
The utility model provides a kind of ultrasonic sensing precision distance measurement device that welds under water, and the utility model has solved the problem that there is poor anti jamming capability in the undersea ranging device.
For addressing the above problem; The utility model adopts following technical scheme: weld ultrasonic sensing precision distance measurement device under water, comprise controller (1), ultrasound wave secondary BPF. (2), sensor drive driving circuit plate (3), underwater ultrasound wave sensor (4) and ultrasound wave filter amplifier (5); The output terminal of controller (1) connects ultrasound wave filter amplifier (5), and ultrasound wave filter amplifier (5) connects the input end of underwater ultrasound wave sensor (4); The input end of controller (1) connects ultrasound wave secondary BPF. (2), and ultrasound wave secondary BPF. (2) connects sensor drive driving circuit plate (3), and sensor drive driving circuit plate (3) connects the output terminal of underwater ultrasound wave sensor (4).
The ultrasonic sensing precision distance measurement device that welds under water of the utility model has stronger antijamming capability.It utilizes special-purpose ultrasonic sensor under water, carries out the analysis of welding base metal pattern based on transit time method, and high-precision undersea ranging is crucial.In order accurately to detect when the distance of front sensor apart from base plate, the key of asking for distance is the judgement of echo due in, because the interference that welding is under water brought, so the system requirements that is designed has stronger antijamming capability.
