Example Embodiment

[0044] Example one

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

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

[0047] S2. Control the industrial camera to take pictures of the indicator light and obtain the image of the test state; the number and frequency of photographs are different for different test items, and the photographing frequency is less than the ...

Example Embodiment

[0057] Example two

[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 test parameters;

[0060] (2) After the tested product is placed in the test tooling, the travel switch outputs the in-position signal of the tested product to the single-chip microcomputer.

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

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

Example Embodiment

[0066] Example three

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

[0068] The definition module is used to accept the definition of the test parameters, and according to the defined test parameters, the single-chip microcomputer controls the on and off of the relay. When the relay is on, the digital button of the electronic lock circuit board under test enters the test mode, and the corresponding connection is now The indicator light on the digital button is in a state indicating the test result of the digital button;

[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] The image analysis module is used to analyze the test status image to obtain the status of the indicator light;

[0071] The comparison and judgment module compares and judges the status of the indicator l...

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...
