Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and in particular to a generator panel assembly test system. Background Technology

[0002] To ensure the normal and reliable operation of the generator, an operation panel, or generator panel, is usually equipped on the generator. This panel is used to display the generator's operating status, monitor various key indicators, control operating functions, and provide warnings in case of faults or abnormalities.

[0003] Testing the generator panel assembly is a crucial step in ensuring the stable, safe, and reliable operation of the generator system. Currently, generator panel assembly testing typically employs a component-by-component testing method, examining each functional module individually and usually displaying the test results (pass or fail) via indicator lights. While this method can quickly ensure the pass / fail status of individual functions, it cannot meet the demands of efficient and accurate quality control for complex panel assemblies with high functional integration. Especially when the panel assembly involves multiple voltages, frequencies, and different national standards (such as Chinese national standards, American standards, and European standards), existing testing devices rely on manual judgment and operation, repeatedly adjusting parameters, and cannot visually display test data (current and voltage). This not only results in low efficiency but also easily leads to misjudgments and omissions.

[0004] Therefore, how to integrate multiple test modules, simplify operation steps, realize automated testing, reduce the need for manual intervention, and improve detection efficiency and accuracy has become an urgent problem to be solved in this field. Utility Model Content

[0045] The output of the automatic detection module 3 is connected to the input of the interrupt control module 4 to switch between DC and AC tests. The output of the automatic detection module 3 is also connected to the control terminal of the DC test module 9 to control the sequential triggering of DC tests.

[0046] The DC output terminal of the interrupt control module 4 is connected to the DC test module 9, the AC output terminal of the interrupt control module 4 is connected to the AC test module 10, and the feedback terminal of the interrupt control module 4 is connected to the input terminal of the display panel 6.

[0048] The structural diagram of the test cabinet in this embodiment is as follows: Figure 2As shown, the test component 2, automatic detection module 3, interrupt control module 4, and power supply module 5 are disposed inside the test cabinet 17, and the test panel 1 is mounted on the surface of the test cabinet 17; the test cabinet includes a sloping mounting area 18 with a forward tilt angle of 45°, on which a display panel 6 is disposed; the horizontal plane 19 below the control panel 7, which is connected to the cabinet body, is used to install the control panel 7 and place the generator panel 16 to be tested; a power output panel 8 is disposed on a vertical plane 20 on one side of the control panel 7, perpendicular to the cabinet body.

[0049] The schematic diagram of the test panel in this embodiment is as follows: Figure 3 As shown, the system includes a display panel 6, a control panel 7, and a power output panel 8. The display panel 6 includes status indicator lights, a voltmeter, and an ammeter corresponding to each module. The ammeter and voltmeter are connected to the AC test module 10 and the DC test module 9, respectively. The status indicator lights are connected to the automatic detection module 3, the interrupt control module 4, and the power module 5, respectively. The control panel 7 has several switches, control buttons, and adjustment knobs corresponding to each module. The switches include a power switch, a power selection switch, a manual / automatic mode switch, a power boost switch, and a power buck switch. The control buttons include a start / stop button, a reset button, and a step button, which are used to control the step-by-step execution of test procedures in manual mode. The adjustment knobs include a transformer adjustment knob.

[0050] The power output panel 8 includes six power output interfaces, including a DC detection integrated output interface (functional detection port), an AC boost interface, an AC buck interface, a socket detection interface, and a load detection interface; the DC detection integrated output interface is used to output simulated generator signals to the switch on / off test module 13, the polarity detection module 14, and the indicator light test module 15 and to receive feedback.

[0051] like Figure 4 The diagram shows a power supply module of this embodiment. The input terminal of the power switch is connected to the power input, and the output terminal of the power switch is connected to the input terminal of the boost / buck circuit and the input terminal of the AC / DC switching power supply, respectively. The AC transformer module 11 in the power supply module 5 includes at least two adjustable transformers and switches connected in parallel for the boost / buck circuit. The output terminals of the boost / buck circuit are connected to their corresponding power output ports, respectively. The output terminal of the AC / DC switching power supply is connected to the power output port.

[0052] After all wiring between the power output panel 8 and the generator panel 16 under test is correctly connected, the system test procedure is as follows: The operator turns on the power switch on the control panel 7, and the entire system is powered on. The automatic / manual test mode is selected through the mode switch. In automatic mode, the automatic detection module 3 will start the DC test process through the interrupt control module 4, controlling each DC test module 9 to run the switch continuity test, polarity detection, and indicator light detection in sequence. After the DC test process is completed, the system switches to the AC test module 10.

[0053] The structural diagram of the switch continuity test module in this embodiment is as follows: Figure 5 As shown: The test equipment simulates the generator's functional signal (12V DC voltage), which is output through the power output panel 8 to the signal input feedback terminal 22 of the switch continuity test module 13, and then provided to the signal switch 21 of the generator panel 16. The signal then returns to the test equipment via the equipment test cable. If the switch starts normally, the circuit continuity feedback is sent to the automatic detection module 3, and the corresponding indicator light 23 on the display panel 6 is illuminated. The automatic detection module 3 switches to the next test module after a delay. In this embodiment, the switch modules to be tested on the generator panel 16 include an ignition switch module, a start switch module, and a fuel switch module.

[0054] The structure diagram of the polarity detection module in this embodiment is as follows: Figure 6 As shown: The test equipment simulates a generator function signal (12V DC voltage), which is output through the power output panel 8 to the signal input feedback terminal 22 of the polarity detection module 14, and provided to the DC detection interface 24 of the module under test on the generator panel 16. The polarity detection module 14 uses the unidirectional conduction performance of the diode 25 to confirm the correctness of the wiring polarity of the module under test on the generator panel 16. If the wiring is correct, the circuit is turned on and feedback is sent to the automatic detection module 3, and the indicator light 23 is lit. After a delay, the automatic detection module 3 switches to the next test module. In this embodiment, the polarity detection of the generator panel 16 includes the detection of charging function, DC output function, and cigarette lighter function.

[0055] The structural diagram of the indicator light module in this embodiment is as follows: Figure 7 As shown: The test equipment simulates a generator function signal (12V DC voltage), which is output through the power output panel 8 to the signal input feedback terminal 22 of the indicator light test module 15. This signal is then supplied to the positive and negative terminals of the indicator light 26 on the generator panel 16 via the power output panel 8. If the module under test is operating normally, the circuit is activated, feeding back to the automatic detection module 3, illuminating the indicator light 26 and simultaneously lighting the indicator light 23 on the display panel 6. After a delay, the automatic detection module 3 shuts down the DC test module 9 and switches to the AC test module 10. In this embodiment, the indicator light test includes the detection of the oil pressure indicator light and the choke function indicator light.

[0056] If an abnormality is detected in the DC test module 9, the connection of the DC test module 9 will be disconnected through the interrupt control module 4, and the fault indicator light on the display panel 6 will be lit. At this time, the operator can determine the faulty module by the signal light 23 of the test module that is not lit.

[0057] After the DC test process is completed, the automatic detection module 3 will start the AC test module 10 through the interrupt control module 4. During the AC test, the socket function test module 27 and the load test module 28 run in parallel.

[0058] The structure diagram of the socket function test module is as follows: Figure 8 As shown, the socket function test module 27 is used to detect whether the generator socket 29 has power output and whether the leakage protection function of the generator socket 29 is normal. For ordinary sockets that do not require leakage current detection, the leakage detection switch 30 is turned off, and the function is judged by the illumination of the indicator light 23. For sockets with leakage protection, leakage current needs to be detected. Then, the leakage detection switch 30 is closed, and the leakage current adjustment knob 31 is adjusted. The leakage current is displayed on the display panel by the leakage current meter 32, adjusting the leakage current from the minimum value to the maximum value required by the technical specifications. When the leakage current is less than the technical specification value, the indicator light 23 is lit, and the leakage protection switch is turned on. When the leakage current reaches the maximum value of the technical specifications, the indicator light 23 is still lit, and the leakage protection switch is turned on, indicating that the function is normal.

[0059] The load testing module structure diagram is as follows: Figure 9 As shown, the load test module 28 is used to perform load tests and detect whether the power indicator module 33 on the generator panel 16 is operating normally. In this embodiment, the energy-saving function of the generator panel assembly under test is as follows: When the load is less than 200W, the green indicator light 34 on the power indicator module 33 illuminates, indicating it is in idle mode; when the load is greater than 200W, the red indicator light 35 on the power indicator module 33 illuminates. The load test module 28 divides the load test circuit into two paths. The first load indicator light 36 is a 250W incandescent lamp with a rated voltage of 220V, and the second load indicator light 37 is a 150W incandescent lamp with a rated voltage of 220V, used to simulate appliances with power less than 200W and greater than 200W. The load test module 28 selects the path via the power selection switch 38. If the power indicator module 33 is operating normally, when less than 200W is selected, the green light on the panel assembly illuminates; when greater than 200W is selected, the red light on the panel assembly illuminates.

[0060] In manual mode, each of the above test steps needs to be executed step by step using the step button, which is suitable for operators to check the function of each test module one by one.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
