Embodiment 1

[0045] This embodiment provides a method for testing an electronic lock circuit board, which is used on a host computer, such as figure 2 shown, including:

[0046] S1. Define the test parameters, and control the on-off of the relay through the single-chip microcomputer according to the defined test parameters. When the relay is turned on, the digital keys of the electronic lock circuit board under test enter the test mode and test one by one. At this time, the corresponding keys connected to the digital The indicator light of the button is in the state showing the test result of the digital button, and in a specific embodiment, the indicator light can be located on the upper half of the circuit board under test, and there are only two indicator lights, red and blue;

[0047]S2. Control the industrial camera to take pictures of the indicator light to obtain the test status image; the number of pictures taken and the frequency of the pictures are different for different test i...

Embodiment 2

[0058] This embodiment provides a method for testing electronic lock circuit boards, such as image 3 shown, including:

[0059] (1), the upper computer accepts the definition of the test parameters;

[0060] (2) After the product under test is placed on the test tool, the limit switch outputs the in-position signal of the product under test to the microcontroller,

[0061] (3), the single-chip microcomputer receives the in-position signal and controls the on-off of the relay according to the defined test parameters. When the relay is turned on, the digital keys of the electronic lock circuit board under test enter the test mode, which is correspondingly connected to the digital keys at this time. The indicator light of the button is in the state of indicating the test result of the number key;

[0062] (4), the host computer controls the industrial camera to take pictures of the indicator light, obtains the test state image, analyzes the test state image, and obtains the st...

Embodiment 3

[0067] In this embodiment, an electronic lock circuit board testing device is provided, which is used on a host computer, such as Figure 4 shown, including:

[0068] The definition module is used to accept the definition of the test parameters, and control the on-off of the relay through the single-chip microcomputer according to the defined test parameters. When the relay is turned on, the digital keys of the electronic lock circuit board under test enter the test mode. The indicator light of the number key is in the state of indicating the test result of the number key;

[0069] The control module is used to control the industrial camera to take pictures of the indicator light and obtain the test status image;

[0070] An image analysis module, configured to analyze the test state image to obtain the state of the indicator light;

[0071] The comparison and judgment module compares and judges the state of the indicator light with the preset result state to obtain the fina...

Abstract

The invention provides a method, a device and a system for testing a circuit board of an electronic lock. The method comprises the following steps: S1, defining test parameters, and controlling the on-off of a relay through a single-chip microcomputer according to the defined test parameters, wherein when the relay is switched on, digital keys of a tested electronic lock circuit board enter a testmode, and at the moment, indicating lamps correspondingly connected to the digital keys are in a state of indicating test results of the digital keys; S2, controlling an industrial camera to photograph the indicator lamp to obtain a test state image; S3, analyzing the test state image to obtain the state of the indicator lamp; and S4, comparing and judging the state of the indicator lamp with a preset result state to obtain a final test result. The single-chip microcomputer is used for controlling the on-off of the relay to replace a manual operation key, and the image recognition technologyis used for replacing manual subjective judgment, thereby reducing the workload of manual testing, improving the testing efficiency, and improving the testing accuracy and stability, and of the method, the device and the system have great significance to the improvement of the automation degree of testing.

Description

technical field [0001] The invention relates to an electronic lock circuit board testing method, device and system. Background technique [0002] The electronic lock is a combination lock product with buttons. The test of its circuit board needs to manually press the corresponding number button to enter the test mode test according to the test item, and judge whether the product is qualified according to the state of the light and the number of flashes, and the test efficiency Low, high operating requirements for employees (need to keep in mind the key test sequence, and the response of each test), high work intensity, long-term testing is easy to fatigue, subjectively affect the judgment of test results, resulting in poor reliability, no system card control, resulting in testing The results cannot be traced back. [0003] Chinese Utility Model No. CN207212012U disclosed in 20180410 discloses an electronic lock testing device, which includes a power supply, a controller con...
