All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0018] Example

[0019] like Figure 1 and Figure 2As shown, a test circuit for testing equipment based on a motor control circuit board includes a power supply 1, a processing control module 2, a relay 3, several quick interfaces 4, an analog output module 5, and an analog input module 6. The power supply end of the power supply 1 is connected to the processing control module 2, the relay 3, and the input end of the quick interface 4. The control end of the processing control module 2 is connected to the controlled end of the relay 3. The output end of the analog input module 6 is connected to the input end of the processing control module 2 through the quick interface 4. The output end of the relay 3 is connected to the input end of the quick interface 4. The output end of the quick interface 4 is connected to the input end of the analog output module 5. The output end of the analog output module 5 is connected to the filter.

[0020] The model of the processing control module 2 in the present invention is USB6009.

[0021] The quick interface 4 in the present invention is an aviation plug.

[0022] The power supply range of the power supply 1 in the present invention is DC5V~24V.

[0023] The working principle of this utility model is as follows:

[0024] The processing control module can communicate with the motor control circuit board through the serial port or USB conversion interface to obtain the operating parameters of the motor control board.

[0025] The processing and control module uses the USB6009 acquisition card as the processing and control center. The processing and control module controls the relay module to automatically power on and off the power supply, thereby enabling the relay to switch the voltage channel. The filter (FLUKE8808A) realizes voltage detection; and the analog input module realizes analog quantity acquisition (8-channel analog input) through USB6009.

[0026] The utility model adopts a quick connector (aviation plug) to realize the reuse of the test system. A set of test equipment is shared for different motor control circuit boards. Only different test fixtures need to be replaced, different test documents need to be edited, and different test programs need to be called to realize the reuse of the test equipment, thereby shortening the test development cycle.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
