It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, an embodiment of the utility model provides an automatically controlled board testing arrangement of frequency conversion product can include:
the device comprises a microprocessor 101, at least one signal simulation circuit 102, at least one light indication circuit 103, a first communication interface circuit 104, a toggle switch 105, an input module 106 and a display 107 which are respectively connected with the microprocessor 101;

The embodiment of the utility model provides an automatically controlled board testing arrangement of frequency conversion product, the device include microprocessor, a plurality of signal analog circuit, a plurality of light indicating circuit to and communication interface circuit, toggle switch, input module and the display that links to each other with microprocessor respectively. The signal simulated by the signal simulation circuit can be output to the electric control board, and the corresponding test result can be returned to the microprocessor through the communication interface circuit and displayed through the display; the light indicating circuit can make light prompt for the test signal output by the electric control board; the receiving and transmitting toggle switch can control whether the microprocessor is in a receiving state or a transmitting state, namely the data transmission state of the microprocessor is controlled; the input module can input an electronic control board identification. Based on the display content and the light prompt effect of the display, the test result of each test item of the electric control board can be obtained, and the test design can cover all the test items which are possibly required, so that the universality is high.
In detail, the test object of the test device is a frequency conversion product electric control board, such as a frequency conversion refrigerator electric control board, a frequency conversion air conditioner electric control board, and the like.
In detail, the test of the electric control board usually involves a plurality of test items, for example, when the electric control board of the inverter refrigerator needs to be tested, the humidity, the temperature, the smell and the door switch are usually required to be tested. Therefore, the signal simulation circuit can respectively simulate a humidity signal, a temperature signal, an odor signal and a door switch signal, and can be realized by the existing circuit design. Furthermore, the number of signals may typically be more than one for the same analog signal. For example, to test the temperature of each compartment of a refrigerator, it is often necessary to simulate the temperature signals for each compartment of the refrigerator.
In detail, the signal analog circuit may realize generation of an analog signal based on a precision potentiometer. Among them, the precision potentiometer is a variable resistor capable of adjusting its own resistance value with high precision. Therefore, a tester can manually adjust the precision potentiometer as required to simulate an analog signal with an expected value, namely, the value can be realized by adjusting the resistance value.
After the connection relation with the electric control board is established, the analog signal generated by the signal analog circuit can be output to the corresponding signal acquisition module of the electric control board. Furthermore, the signal actually acquired by the signal acquisition module can be transmitted to the microprocessor in a receiving state through the first communication interface circuit, and the information of the signal is displayed through the display. The tester can test whether the corresponding channel of the electric control board is normal or not by comparing the numerical value simulated by the tester through operation control with the numerical value displayed by the display.
Besides the test process, some test signals output by the electric control board can be tested through the light indicating circuit. For example, under the control of a tester, the microprocessor in the sending state can issue some test commands to the electric control board of the variable frequency refrigerator through the first communication interface circuit, so that the electric control board can output an indicator light signal, a fan signal, an air door signal, a switching valve signal, a direct current heater signal and an alternating current heater signal. The test signals can be respectively output to corresponding light indicating circuits in the test device, so that the light indicating circuits perform corresponding light indication. The tester can know whether each test signal is normal according to the light indication.
In detail, the test process may involve input or output of signals, and in consideration of the unidirectional input/output of signals, a tester may operate the toggle switch as required to adjust the receiving or transmitting state of the test device accordingly. For example, the test apparatus should be set to a transmission state when it needs to output a signal, and to a reception state when it needs to input a signal.
In detail, since the types, categories, etc. of the electric control boards in different batches on the production line may be different, before the electric control boards are tested, identification information of the electric control boards, such as a head code of the test board, is usually set, i.e., a testing device is required to determine which electric control board is to be tested. In particular, the tester may input this identification information through an input device. In general, after the input is performed for the first time, the parameters set last time are still kept when the power is switched on next time, so that the same-specification multi-board test is facilitated.
In detail, the connection between the electronic control board and the testing device may be generally through a physical connection. For example, a communication interface circuit of the electronic control board and a communication interface circuit of the testing device need to be connected, a signal acquisition module of the electronic control board and a corresponding signal simulation circuit of the testing device need to be connected, and a test signal output interface of the electronic control board and a corresponding light indication circuit of the testing device need to be connected. After the test of the current electric control board is finished, all established connecting lines can be dismantled, and the next electric control board can be connected according to the same connecting line mode, so that the next electric control board is tested. Of course, because the test requirements of different electric control boards are different, and the test type and the test quantity on the test device are set to be relatively maximized, only the items to be tested need to be correspondingly connected during connection. For example, fig. 2 shows a schematic connection relationship between an electric control board of a variable frequency refrigerator and the testing device.
In this embodiment, because the detection channel is equipped with redundantly, so not only can satisfy current automatically controlled board and detect, but also have the practicality to the new product in later stage. The testing device has strong universality and can be suitable for various electric control boards, so that the testing device has the advantages of standard testing, correspondingly improved testing efficiency, difficulty in damage and the like.

In this embodiment, in view of the fact that the input operation related to the testing device is usually simple and infrequent, a button input module may be used instead of a touch screen input module to save cost. As shown in fig. 2, 17, 18, 19, 20 shown in fig. 2 may be the 4 third pins. These 4 keys may correspond to K1, K2, K3, and K4, respectively, shown in fig. 2.

Thus, when the test of the current electric control board is finished and the next electric control board is connected, the identification information can be directly utilized without repeated input.
