Embodiment Construction

[0015] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0016] In order to weaken the near-range reverberation and solve the contradiction between the minimum sounding and the maximum sounding, the echo sounder of the present invention adopts different transmitting powers and transmitting pulse widths corresponding to different measuring ranges. The transmit power and transmit pulse width are controlled by the MCU controller. Corresponding to different ranges, the MCU controller outputs power control commands to enable the booster unit to generate various transmit voltages for the transmit power amplifier.

[0017] see figure 1 and figure 2 As shown, it is a structural schematic diagram of the echo sounder of the present invention, wherein the sounder includes a host computer, a sounder main board, a power distribution module, a display and a transducer, and t...

Abstract

The invention relates to an echo sounder. The echo sounder comprises an upper computer, a sounder main board, a power distribution module, a displayer and a transducer. The upper computer is connected with the sounder main board, the power distribution module and the displayer, the power distribution module is connected with the sounder main board and the displayer, the transducer is connected with the sounder main board, and the sounder main board comprises an MCU, an emitting driver, an emitting power amplifier, a boosting unit, an impedance matching unit and a receiving power amplifier. The receiving power amplifier comprises a prime amplifier, a gain control amplifier, a band-pass filter, a post amplifier and an envelope detector. By means of the echo sounder of the structure, an echo sounder circuit is simplified, miniaturization of the structure of the sounder is achieved, the weight of the sounder is reduced, and the sounder is accordingly portable, convenient to fix and wide in application range.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to electronic equipment, in particular to an echo sounder. Background technique [0002] With the rapid development of processors, the echo sounder has fewer and fewer circuits and is more and more simple. The traditional echo sounder is expensive, heavy, and has poor reliability and accuracy. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide an echo sounder capable of simplifying the circuit structure of the echo sounder, miniaturizing the entire echo sounder, and reducing the weight of the echo sounder. [0004] In order to achieve the above object, the echo sounder of the present invention has the following composition: [0005] The echo sounder, its main feature is that the sounder includes a host computer, a sounder main board, a power distribution module, a display and a t...
