Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a panoramic system control board testing device and system. Background Art

[0002] The 360-degree panoramic system is a car assisted driving system, which is mainly composed of 4 cameras, a system control and video processing unit and a video display unit. Generally, each function of the panoramic system is realized through an integrated control panel. In the actual production process, the control panel of the 360-degree panoramic system needs to be tested before leaving the factory. The existing test device consists of a test bracket, 4 cameras, a display screen and related cables. On the one hand, during the test, the tester needs to manually plug and unplug the power cord, video cable and camera cable, which is cumbersome. On the other hand, the placement of each camera on the test platform needs to be fixed in a specific place to collect video images of a specific environment, so that each time when different control panels are tested, the images received by different control panels are consistent. In this way, the video processing function of each control panel can be evaluated with a unified standard. However, in the actual test process, since the camera shoots the real scene, the shooting scene will change due to the movement of people or other factors. If the same standard is used to evaluate the video processing function of each control panel, it may cause misjudgment of the test results of individual control panels. Summary of the invention

[0046] In a preferred embodiment, it also includes a connector 22; the connector 22 is arranged on the first test adapter board 24; the first test adapter board 24 is connected to the computer terminal through the connector 22; the camera data simulator 17 is connected to the first test adapter board 24 through the connector 22; the connector 22 is used to transmit the video data to the panoramic system control board 3 to be tested, and when receiving the video signal to be tested, transmit the video signal to be tested to the computer terminal.

[0047] In a preferred embodiment, it further comprises: a video adapter; the video adapter is connected to the connector 22 and the computer terminal; the video adapter is used to convert the format of the video signal to be tested and output the converted video signal to be tested to the computer terminal.

[0048] In a preferred embodiment, it also includes a power connector 16, a first bull horn socket 7 and a second bull horn socket 9; the power connector 16 is connected to the second test adapter board 15; the first bull horn socket 7 is connected to the first test adapter board 24; the second bull horn socket 9 is connected to the second adapter board; the first bull horn socket 7 is connected to the second bull horn socket 9.

[0049] In a preferred embodiment, the first test adapter board 24 , the second test adapter board 15 , the connector 22 , the camera data simulator 17 and the video converter 18 are all arranged in a bakelite box 6 .

[0050] The following is combined with Figure 1 The structure of the panoramic system control board testing device disclosed in the present invention is further described;

[0051] The panoramic system control board test device is mainly composed of a bracket 1, a bakelite box 6, a pressure head 2, a test ejector pin 5, a test adapter board, a camera data simulator 17, a video converter 18 and a connecting line.

[0052] Preferably, the bracket 1 is a bakelite bracket 1, and the pressure head 2 is an acrylic pressure head 2; the first test adapter board 24 and the second test adapter board 15 are connected through the second copper column 11 and the fourth copper column 14, and are fixed in the bakelite box 6 through the first copper column 10 and the third copper column 13. The connector 22 is a 32pin in connector 22, and the first bullhorn seat 7 and the second bullhorn seat 9 are both 50pin in simple bullhorn seats; the connector 22 and the first bullhorn seat 7 are directly welded on the first test adapter board 24. The DC power connector 16 and the second bullhorn seat 9 are directly welded on the second test adapter board 15. The first test adapter board 24 and the second test adapter board 15 are electrically connected through the first connecting line 8, wherein the first connecting line 8 is a 50pin flexible flat cable; the first test adapter board 24 sends the test signal of the panoramic system control board 3 to be tested to the second test adapter board 15 for processing through the first connecting line 8. It should be noted that the test signal includes but is not limited to the voltage signal to be tested, the current signal to be tested and the video signal to be tested, and in some optional embodiments, it can also include test signals of other functional interfaces; the first test adapter board 24 will send other test signals except the video signal to be tested to the second test adapter board 15, and the second test adapter board 15 will extract the corresponding test value of the panoramic system control board 3 to be tested according to the test signal, and then input it to the external computer terminal through the second connecting line 12. For example, if the second test adapter board 15 receives the voltage signal to be tested, the second test adapter board 15 will extract the corresponding voltage value according to the voltage signal to be tested, and then input the voltage value to the external computer terminal. It should be noted that the second test adapter board 15 is connected to an external computer terminal via a second connection line 12. The computer terminal generates a test result or directly displays the test value according to the received test value.

[0053] In a preferred embodiment, all the signals to be tested except the video signal to be tested are processed by the second test adapter board, and the corresponding test values ​​are extracted and transmitted to the computer terminal, which displays the test values ​​and generates test results, which refer to whether the test is passed or not. The tester can check the test value of each test item to know which test is failed, so as to provide maintenance information to the maintenance personnel.

[0054] In other preferred embodiments, for other test signals except the video signal to be tested, after the second test adapter board extracts the corresponding test values, the second test adapter board also generates the test results (i.e., makes a judgment on whether the test passes or fails), and the computer terminal at this time only serves as a display to display the test results generated by the second test adapter board.

[0055] In a preferred embodiment, the second test adapter board 15 can also be connected to a display device via the second connecting line 12, and the display device directly displays the test value.

[0056] In addition, the second test adapter board 15 connects the power from the DC power supply connection to the first test adapter board 24, and then the corresponding test pins 5 provide power to the panoramic system control board to be tested.

[0057] The camera data simulator 17 is connected to the connector 22 via the fifth connection line 21, which is a camera cable, so that the video data output by the camera data simulator 17 is connected to the first test adapter board 24, and then connected to the panoramic system control board 3 to be tested. After receiving the video data, the panoramic system control board 3 to be tested will process it and then input the video signal to be tested. The video processing function of the panoramic system control board to be tested is evaluated in the above manner.

[0058] It should be noted that the camera data modeler sends the same video data when testing different panoramic system control boards 3 to be tested; that is, the camera data simulator 17 outputs fixed video data when testing a batch of panoramic system control boards, so that the same evaluation standard can be used later to reduce the misjudgment rate when judging the video processing function of each panoramic system control board. The camera data simulator 17 can be a device that can output video images, and it only needs to keep the output video image unchanged. However, the traditional test device uses a camera to collect real-time video data, and it cannot guarantee that the input video image is consistent when testing each panoramic system control board. If the input video image is inconsistent, then after each panoramic system control board 3 to be tested processes the input video image, the input video image will also be inconsistent. At this time, if the video processing function of each panoramic system control board 3 to be tested is evaluated with a unified evaluation standard, it may cause misjudgment.

[0059] The video converter 18 is connected to the connector 22 via the fourth connection line 20, which is a video cable, so that the video signal to be tested generated by the panoramic system control board 3 to be tested and received by the first test adapter board 24 can be connected to the video converter 18, and the video converter 18 uploads the converted video signal to be tested to the computer terminal via the third connection line 19, which is also a video cable. In addition, the video signal to be tested generated by the panoramic system control board 3 to be tested can also be directly output to the computer terminal via the sixth connection line 23. Since the video signal needs to pass through the video collector before it can be given to the computer terminal, and some existing video collectors can only collect signals in CVBS and AHD formats, in the present invention, if the panoramic system control board 3 to be tested outputs the video signal to be tested in CVBS format, it is directly uploaded to the video collector through the sixth connecting line 23 and then input into the computer terminal. If the panoramic system control board 3 to be tested outputs the video signal to be tested in VGA format, the video signal to be tested is transmitted to the video converter 18 through the fourth connecting line 20. After the video converter performs format conversion, it is input into the video collector through the third connecting line 19 and then input into the computer terminal.

[0060] In the present invention, after receiving the video signal to be tested, the computer terminal extracts the video image to be tested according to the video signal to be tested, and compares the video image to be tested with a preset standard image to generate a test result corresponding to the video signal to be tested; specifically, the computer terminal compares the similarity between the video image to be tested and the preset standard image. If the similarity exceeds a preset threshold, the video processing function of the panoramic system control board 3 to be tested is normal, otherwise it is abnormal. When comparing the similarity between the video image and the standard image, the comparison can be performed using an existing image comparison method.

[0061] In addition, after receiving the test value input by the second test adapter board 15, the computer terminal compares the test value with the preset standard value interval. If the test value is within the preset standard value interval, the test function corresponding to the panoramic system control board 3 to be tested is normal, otherwise it is abnormal. In the present invention, other test signals except the video signal to be tested are processed by the second test adapter board. After the second test adapter board judges and processes the extracted test signal, it directly outputs the test result and each test value to the computer for display.

[0062] In another optional embodiment, the computer terminal does not automatically generate corresponding test results, but only displays them, acting as a display device to display the video image corresponding to the video signal to be tested, or to display the test values ​​such as voltage values, current values, and test results transmitted from the second test adapter board, which are then manually determined by staff.

[0063] Based on the above understanding, in a preferred embodiment, the second connecting line 12, the third connecting line 19 and the sixth connecting line 23 are not connected to the computer terminal, but are connected to a display terminal such as a display screen, and the display screen displays the video image to be tested of the panoramic system control board 3 to be tested and each test value, which can then be manually determined by the staff.

[0064] In the present invention, all the test pins 5 are fixed on the upper panel of the bakelite box 6, and the pins of the test pins 5 are directly welded on the first test adapter board 24 to increase the firmness; each test point on the panoramic system control board 3 to be tested corresponds to a test pin 5; during the test, the panoramic system control board 3 to be tested is placed in the tray 4, and the acrylic pressure head 2 is pressed down to keep each test point of the panoramic system control board 3 to be tested in good contact with each test pin 5 to ensure the accuracy of the test result.

[0065] Based on the above embodiments, another embodiment of the present invention provides a panoramic system control board test system, including a plurality of panoramic system control board test devices according to any one of the above embodiments of the present invention, a computer terminal and a cloud server;

[0066] Each of the panoramic system control panel testing devices is connected to the computer terminal, and the computer terminal is connected to the cloud server;

[0067] The computer terminal is used to generate a test result of each panoramic system control board to be tested according to the video signal to be tested or the test value output by each panoramic system control board testing device, and upload each test result to the cloud server.

[0068] In this embodiment, each panoramic system control board test device is connected to a computer terminal, which receives the video signal or value to be tested output by each panoramic system control board test device, generates the test result, and then uploads it to the cloud server for storage, so as to automatically record, track and query the test details of each factory product.

[0069] By implementing the embodiment of the present invention, testers do not need to frequently plug and unplug cables, thereby improving convenience. On the other hand, a camera data simulator is used to replace the camera of the existing test equipment. The camera data simulator outputs unified video data, so that the consistency of the input video image is maintained when testing each panoramic system control board, so that the same standard can be used to evaluate the video processing function of each control board in the future to avoid misjudgment.

[0070] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
