Four dot array fish detection sonar

Abstract

The invention discloses a four-dot matrix fish detection sonar, which includes the four sonars fixed on the chassis, a control center and a solar panel, the four sonars are distributed in an equidistant square array, and the solar panels are respectively It is connected with four sonar and control center for power supply. The control center includes processing unit, drive module, data storage module, photovoltaic power supply module, wireless transceiver, temperature sensor and communication module. The temperature sensor, four sonar and processing unit Connection, through a relay control switch, the signal receiving circuit is connected with a filter and an amplifying circuit; the processing unit controls the four sonars to be transmitting and receiving sonar or receiving sonar and work in turn, and according to the received sound wave information The position coordinates of the measured fish school are obtained by calculating the temperature information; the four-dot matrix fish detection sonar of the present invention can accurately obtain the position coordinates of the target by placing the control center among the four sonars, with less measurement error and sufficient power supply.

Description

technical field [0001] The invention relates to a four-dot matrix fish detection sonar, which belongs to the technical field of fish school tracking. Background technique [0002] Sonar is an electronic device that uses the propagation characteristics of sound waves under water to complete underwater detection and communication tasks through electro-acoustic conversion and information processing. Under the control of the transmitter controller, the transmitter generates high-power ultrasonic pulse oscillations. After the conversion device, the underwater acoustic transducer emits ultrasonic waves in a certain direction. In this direction, the ultrasonic waves are reflected back when they meet the target, and are received by the underwater acoustic transducer to become electrical signals, and then sent to the receiver through the transceiver conversion device. The machine zooms in, and finally sends it to the display to show the direction and distance of the target. [0003]...

AI Technical Summary

Problems solved by technology

At present, most of the single sonar or dual sonar are used for distance measurement. There are errors in the distance measurement and positioning of single sonar or dual sonar, which cannot be corrected each other or the degree of correction cannot meet the current high-precision positioning requirements.

Due to the heavy positioning tasks and long working hours of sonar equipment, the problem of insufficient power supply is prone to occur
