[0002] With the booming development of the imaging camera industry, more and more cameras are being produced, and their functions are becoming more and more complex. If testing efficiency cannot be improved, it means that factories will need to invest more human resources and equipment resources to complete single-board testing of camera products. How to make good use of production automation testing is crucial. The prerequisite is to build a stable, reliable and highly efficient hardware platform to ensure the accuracy of camera single-board functional testing while improving factory production capacity.

The second type of test items include audio test and video test.

[0041] The main reasons for low test efficiency in existing technologies are the inability to automatically complete audio and video tests on individual boards, the inability to test multiple boards simultaneously, and the need for manual judgment of functional tests. However, the test system designed by the present invention incorporates a network hard disk video recorder (NVR) that can decode the audio and video data output by the test board and can decode multiple test boards simultaneously. This allows for automatic testing without manual judgment, greatly improving test efficiency.

[0042] In one embodiment, if Figure 1 As shown, the single-board test fixture includes a test motherboard; the test motherboard is provided with a main control template and a voltage acquisition module, the voltage acquisition module is electrically connected to the main control template, and the voltage acquisition module is used to collect the input voltage of the single board to be tested and the test point voltage of the single board to be tested.

[0043] In one embodiment, if Figure 1 As shown, the test motherboard is further provided with a current acquisition module, which is electrically connected to the main control template and is used to collect the input current of the single board to be tested.

[0044] In one embodiment, if Figure 1 As shown, the single board test fixture also includes a companion test fixture board; the companion test fixture board is electrically connected to the test motherboard, and the companion test fixture board is used to lead out the hardware interface of the single board to be tested.

[0045] In one embodiment, if Figure 1 As shown, the test fixture board is provided with an infrared lamp drive to alarm output module, a filter drive to alarm output module, a white light lamp drive to alarm output module and an alarm input to reset button signal module.

[0049] In actual application, the test system also needs to use devices such as mouse and keyboard, so the mouse and keyboard are connected through the USB interface of the network hard disk recorder.

[0050] Different test items for the board under test are completed by different parts of the test system. For example, the board test fixture can complete tests including: board input voltage and current testing, board test point voltage testing, signal conversion for board functions, network, and TF card transparent transmission. Network DVR tests include: network communication, audio testing, alarm input and output signal detection, and image testing. Self-test items for the board under test include: TF card status, reset button status, etc.

[0051] The embodiment of the present invention also provides a camera single board automatic testing method, which uses the above-mentioned camera single board testing system to perform single board automatic testing, such as Figure 2 The method includes the following steps: S10-S40.

[0052] S10. Configure test items, where the test items include first-type test items and second-type test items.

[0056] S30: Execute automatic testing of the second type of test items.

[0057] Before steps S20 and S30, after completing the configuration test items, the board to be tested needs to be placed into the board test fixture and ensure that the ejector pins of the board test fixture are in contact with the board to be tested. After this task is completed, the test can be started and the automatic test can be performed. During the test process, the board test fixture will first power on the board to be tested and scan the board barcode. After waiting for 40 seconds, the automatic test will begin. In this embodiment, the entire test process (including startup) for four boards only takes 120 seconds, which greatly improves test efficiency compared to existing technologies.

[0058] It should be noted that the automatic tests of the first type of test items and the second type of test items can be performed simultaneously or separately. Of course, in order to improve efficiency, they are performed simultaneously.

[0059] S40: Generate a test report based on the automatic test results of the first type test items and the second type test items, and upload the report to a display for visual display.

[0060] After the test is complete, the test results of all test items and the test report for the entire test can be viewed on the display. After the tester confirms the completion of the test report, all boards in the current batch are removed from the single board test fixture and classified, and then replaced with the next batch of boards for the next round of testing.

[0061] In one embodiment, step S30 specifically includes the following steps:

[0062] S301. Check whether the current MAC address of the board to be tested is the factory default.

[0063] S302: If it is the factory default MAC address, modify the MAC address of the board to be tested to a randomly generated MAC address.

[0064] S303: The network hard disk video recorder receives the broadcast data packet sent by the single board to be tested, modifies the IP address of the single board to be tested through a private protocol, and completes the network connection.

[0065] S304: The network hard disk video recorder logs in to the account of the board to be tested through a private protocol and sends a request for audio data and video data.

[0066] S305 , the board to be tested performs network packetization on the encoded audio stream and video stream according to the received audio data and video data requests and in accordance with the agreed protocol, and then sends the result to the network hard disk video recorder.

[0067] S306: The network hard disk video recorder parses the network packet to obtain the audio stream and the video stream.

[0068] S307: The network hard disk video recorder decodes the obtained audio stream and video stream to obtain the original audio and video.
