[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to facilitate a clearer understanding of the embodiments of the present application, some relevant knowledge is first introduced as follows.

[0039] At present, electrical appliances need to test the control board before they are put on the market. For example, commercial air conditioners are divided into different models such as unit units, multi-split units, and water units. Their control boards need to undergo multiple tests before mass production and listing. Test items involving strong electricity and communications can currently only be tested on the entire system of the corresponding model. The disadvantages are as follows:

[0040] (1) The test project takes a long time, and the test solutions for different models are incompatible. Testing can only be performed using the whole system test resources of the corresponding model, which affects the project progress;

[0041] (2) External test instruments and loads are required during testing, and the test operation is highly complex;

[0042] (3) During the test, personnel are required to stay on duty and the entire system cannot be powered off. The test data must be continuously recorded to ensure the safety of the test, which results in high labor costs.

[0043] Therefore, the present invention is aimed at the control panels of existing mass-produced electrical appliances, such as various air-conditioning models (unit machine / multi-split machine / water machine), and has built a control panel test device compatible with all models of test items, so that the items originally tested on the whole machine system can be transferred to the engineer's desktop for testing, and no external test instruments and loads are required. Only the tooling power supply needs to be provided, and the tester does not need to continuously record the test data. When the test is completed, the tooling will automatically stop the test, and the tester only needs to read the data information recorded in the tooling to obtain the test data. Through the above-mentioned control panel test device, the control panel test items of all models are compatible, that is, the control panel tests for different models can all be carried out using the same tooling, which improves the test efficiency of the control panel and reduces labor costs.

[0044] Figure 1 is a schematic diagram of the structure of the control panel testing device provided by the present invention, see Figure 1 As shown, the control board testing device 100 includes: a first control chip 101, a first power input module 102, a test function selection module 103, a power output control module 104, a sensor input module 105 and a first communication module 106;

[0045] The first control chip 101 is respectively connected to the first power input module 102, the test function selection module 103, the power output control module 104, the sensor input module 105 and the first communication module 106; the first power input module 102 is connected to the power output control module 104;

[0046] The first power input module 102 is used to supply power to the control board testing device 101;

[0047] The test function selection module 103 is used to select at least one test function for the control board under test;

[0048] The first control chip 101 is used to control at least one of the power output control module 104, the sensor input module 105 and the first communication module 106 to test the control board under test based on the at least one test function selected by the test function selection module 103 to obtain a test result.

[0049] The control panel test device 100 provided by the present invention is compatible with the test items of all models, so that the items originally tested on the whole machine system can be transferred to the engineer's desktop for testing, and no external test instruments and loads are required. The test can be carried out by simply powering the control panel test device 100. After the first power input module 102 powers the control panel test device 100, the first control chip 101 controls at least one of the power output control module 104, the sensor input module 105 and the first communication module 106 to test the control panel under test based on at least one test function selected by the test function selection module 103, thereby being compatible with the control panel test items of all models, that is, control panel tests for different models can be carried out using the same tooling, thereby improving the test efficiency of the control panel and reducing labor costs.

[0050] Optionally, the power output control module 104 is connected to the control board under test; the power output control module 104 is used to supply power to the control board under test.

[0051] exist Figure 1 In the embodiment, the power output control module 104 is connected to the first power input module in the control board under test. The external power only supplies power to the control board test device 100 through the first power input module. The control board test device 100 controls the power output control module 104 to supply power to the first power input module in the control board under test through the first control chip 101, so as to achieve the purpose of controlling the power on and off of the control board under test.

[0052] Optionally, the power output control module 104 includes any one of the following: a) a transistor drive control relay; b) a Darlington array device.

[0053] That is, the power output control module 104 may use a transistor to drive a control relay, and when the relay closes the contact, the control board under test is powered on, and when the relay opens the contact, the control board under test is powered off.

[0054] In addition to using a transistor to drive a control relay to build the power output control module 104, a Darlington array device can also be used as a circuit component.

[0055] Optionally, the test function includes at least one of the following:

[0056] a) Communication test, used to test whether the communication related functions of the control board under test are normal;

[0057] b) Power supply test, used to test whether the power supply related functions of the control board under test are normal;

[0058] c) Reliability test, used to test the reliability of the control board under test.

[0059] In the embodiment of the present invention, the control board testing device 100 is compatible with test function items of different models. The test function selection module 103 can select different types of test function items to test the control board under test.

[0060] In actual applications, the test function selection module 103 may use switch devices such as pins and dials in addition to the selection switch to select different types of test function items.

[0061] Figure 2 This is one of the logic diagrams of the control board testing device provided by the present invention for testing the control board under test, see Figure 2 As shown:

[0062] The control board testing device 100 includes: a first control chip 101 , a first power input module 102 , a test function selection module 103 , a power output control module 104 , a sensor input module 105 and a first communication module 106 .

[0063] The control board 200 under test includes: a second control chip 201 of the control board under test, a second power input module 202 , a second communication module 203 and a power output module 204 .

[0064] Optionally, the first control chip module 101 performs a communication test on the control board 200 under test, which can be specifically implemented in the following manner:

[0065] When the test function is the communication test, the first communication module 106 is used to control the control board 200 under test to communicate with the control board testing device 100 ; and the test result is determined based on the communication result.

[0066] In the embodiment of the present invention, the control board testing device 100 communicates with the tested control board 200 using the first communication module 106 ; the tested control board 200 communicates with the control board testing device 100 using the second communication module 203 .

[0067] Based on the communication result, the test result determined is the communication test result. When the test function selection module 103 is set to the communication test program, the control board test device 100 is powered on through the first power input module 102, and the second power input module 202 in the control board 200 under test is powered on by connecting with the power output control module 204. The control board test device 100 communicates with the control board 200 under test after being powered on, wherein the communication scheme includes models such as multi-split / unit machine / water machine, units such as internal machine / external machine / controller, and multiple communication protocols. After the above different models, units and communication protocols are combined, the communication schemes of all models are covered.

[0068] During the power-on duration, if the control board testing device 100 communicates normally with the tested control board 200, the test result is recorded as "communication normal"; if the communication is abnormal, the test result is recorded as "communication abnormal".

[0069] Optionally, the first control chip module 101 performs a power supply test on the control board 200 under test, which can be specifically implemented in the following manner:

[0070] In the case where the test function is the power supply test, the target signal output by the control board under test to the sensor input module 105 is received; and the test result is determined based on the reception result of the target signal.

[0071] In the embodiment of the present invention, the test result determined based on the reception result of the target signal is the power test result. When the test function selection module 103 is set to the power test program, the control board 200 under test outputs the target signal to the control board test device 100 after powering on.

[0072] See also Figure 2 As shown, the target signal is a 5V weak current signal sent by the power output module 204 in the tested control board 200 to the sensor input module 105 in the control board testing device 100 .

[0073] Correspondingly, if the control board testing device 100 normally receives the 5V signal transmitted from the tested control board 200, the test result is recorded as "normal"; if the received 5V signal is abnormal, the test result is recorded as "abnormal".

[0074] Optionally, the first control chip module 101 performs a reliability test on the control board 200 under test, which can be specifically implemented in the following manner:

[0075] When the test function is the reliability test, the power output control module 104 is controlled to supply power to the control board 200 under test at a preset frequency within a preset time period; after the preset time period ends, the test result is determined based on the judgment result of whether the various functions of the control board 200 under test are normal.

[0076] In the embodiment of the present invention, when the test function selection module 103 is set to a reliability test program, the first control chip module 101 in the control board test device 100 controls the power output control module 104 to supply power to the control board 200 under test at a preset frequency. After the test is completed, it is verified whether the communication, power supply and other functions of the control board 200 under test are normal.

[0077] In actual application, different test items can be selected for all models through the test function selection module 103. Table 1 shows that 3 different test items can be selected for 5 models using a 4-bit DIP switch.

[0080] Figure 3 This is the second logical schematic diagram of the control board testing device provided by the present invention testing the control board under test, see Figure 3 As shown, the control board testing device 300 includes: a first control chip 101, a first power input module 102, a test function selection module 103, a power output control module 104, a sensor input module 105, a first communication module 106, a data storage module 107 and a wireless module 108.

[0081] The first control chip 101, the first power input module 102, the test function selection module 103, the power output control module 104, the sensor input module 105 and the first communication module 106 are connected to the Figure 1 To avoid repetition, they are not described again here.

[0082] The data storage module 107 is used to store the test results, or clear the stored test results.

[0083] Optionally, the data storage module is an electrically erasable programmable read only memory (EEPROM) having control capabilities for storing test data and adjusting test program time.

[0084] In actual application, when the test function is a communication test, the control board test device 300 communicates with the control board 200 under test after power-on. During the power-on duration, if the control board test device 300 communicates normally with the control board 200 under test, the normal communication data is recorded in the data storage module 107; if the communication is abnormal, the abnormal communication data is recorded in the corresponding position of the data storage module 107.

[0085] When the test function is a power supply test, the control board 200 under test outputs a target signal (for example, a 5V weak current signal) to the control board test device 300 after being powered on. If the control board test device 300 receives the target signal normally, the normal data is recorded in the data storage module 107. If the received signal is abnormal, the abnormal data is also recorded in the corresponding position of the data storage module 107.

[0086] When the test function is a reliability test, the control board test device 300 controls the power output control module 104 to control the power supply of the board under test at a preset frequency. After the test is completed, the communication function of the control board under test 200 is verified and the data is recorded in the data storage module.

[0087] It should be noted that the PC is connected to the data storage module 107, and can read the test result data, and can also perform data clearing operations on the test result data. During the test process, the power can be turned off at any time, and the current test data can be read at any time.

[0088] The wireless module 108 is used to assist the terminal in establishing wireless communication with the first control chip 101 , and the terminal is used to control the first control chip 101 .

[0089] In actual applications, a terminal, such as a mobile phone or a laptop computer, uses an APP to establish communication with the first control chip 101 through the wireless module 108 to remotely control the start and stop of the control board test device 300 .

[0090] In the above Figures 1 to 3 In the control board test device, no human intervention is required during the test of the control board under test, and the whole process is automatically carried out after power-on in the preset test mode. At the same time, the control board test device can also be connected to multiple control boards under test at the same time, and the number of control boards under test can be flexibly increased or decreased, so that multiple control boards under test can be tested at the same time.

[0091] It should be noted that by configuring the data storage module in the control panel test device, the tester does not need to continuously record the test data. When the test is completed, the tooling will automatically stop the test. The tester only needs to read the data information recorded in the tooling to obtain the test data. In addition, the tester can read the data at any time when the power is turned off, and the experimental data will not be lost after the power is turned on again, which meets the test needs in the event of an unexpected power outage.

[0092] By configuring a wireless module in the control panel test device, the tester does not need to operate on site, and can remotely control the control panel test device through the APP.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
