Problems solved by technology

It is troublesome to realize the sea test; generally, the water depth of the pool is less than 10 meters, and only the general function test can be carried out, and the range test of the depth sounder / fish finder cannot be carried out, especially the high range range, which cannot be tested
Therefore, there are disadvantages such as long cycle, low efficiency and high cost
In the domestic market, there is no detection equipment that integrates depth sounder / fish finder simulators and transducer testers.

Embodiment 1

[0030] see figure 1 , a hand-held depth sounder / fish finder / transducer tester, the hand-held depth sounder / fish finder / transducer tester includes an MCU micro control unit, an LCD display control circuit, a button control circuit, Charging interface circuit, ultrasonic receiving module, ultrasonic transmitting module, underwater acoustic transducer testing module, said LCD display control circuit, key control circuit, charging interface circuit, ultrasonic receiving module, ultrasonic transmitting module, underwater acoustic transducer testing The modules are all connected with the MCU micro control unit, and other circuits and functional modules are controlled by the MCU micro control unit. When the tester is connected with the depth sounder / fish finder, the depth sounder / fish finder transmits a pulse signal with a certain frequency, width, period, and peak-to-peak value into the tester, which can be detected by the ultrasonic receiving module and the MCU micro control unit. ...

Embodiment 2

[0032] see figure 1 , As an improvement of the present invention, the handheld depth sounder / fish finder / transducer tester also includes a display screen, buttons, a transducer interface, and a depth sounder / fish finder interface.

[0033] The display screen is connected to an LCD display control circuit, and the LCD display control circuit is used to control the backlight of the display screen;

[0034] The button is connected to a button control circuit, and the button control circuit controls the use of each button on the tester;

[0035] One end of the transducer interface is connected to the underwater acoustic transducer test module, and the other end is used to connect to the transducer;

[0036] One end of the interface of the depth sounder / fish finder is connected to the ultrasonic receiving module and the ultrasonic transmitting module at the same time, and the other end is used to connect to the depth sounder / fish finder;

[0037] The charging interface circuit is...

Embodiment 3

[0039] see figure 2, as an improvement of the present invention, the ultrasonic receiving module includes LED input status light control circuit, LED input status light, voltage divider circuit, timer / counter, MCU PCA module, MCU interrupt module, MCU timer / counter, peak hold circuit, A / D sampling. The ultrasonic receiving module is used to receive and detect the pulse signal emitted by the depth sounder / fish finder, and is controlled by the MCU micro control unit to transmit the pulse signal frequency, width, peak-to-peak value of the detected depth sounder / fish finder Displayed on the LCD screen; when the tester detects the input of the transmit pulse signal, the LED input status light flashes. The input pulse signal, through the voltage divider circuit, attenuates the peak-to-peak value of the input pulse to the range of 0~5V, and then obtains the frequency, width, Period, the peak-to-peak value of the input pulse is obtained through the peak hold circuit and A / D samplin...

Description

technical field [0001] The invention relates to a tester, in particular to a hand-held depth sounder / fish finder / transducer tester, which belongs to the technical field of detection and maintenance of marine equipment. Background technique [0002] The depth sounder is used to measure the water depth of the sea area where the ship is located, which is of great significance to ensure the safety of the ship's navigation. Fish finder is an electronic device specially used to detect the distribution of underwater fish schools. As an auxiliary equipment for marine fishing, it can not only increase the output of fishery fishing, but also promote the development of marine fishing industry. [0003] In order to ensure that the depth sounder / fish finder can work normally during long-distance voyages and ocean operations, it is necessary to strengthen the daily inspection, repair and maintenance of the depth sounder / fish finder. Since the transducer must be connected to the depth sou...
