Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted equipment testing, and in particular to automated testing equipment for compatibility of vehicle-mounted application systems. Background Art

[0002] With the rapid development of the automobile industry, people's requirements for in-car entertainment experience are constantly improving. In various application systems, external storage devices, such as USB flash drives or SD cards, are generally equipped to achieve functions such as playing audio and video, browsing pictures and reading e-books, providing users with rich visual and auditory experiences. At present, the mainstream USB flash drives and SD cards on the market include more than a dozen brands. The capacity of each brand of USB flash drives and SD cards ranges from 512M, 1G to 256G, with a total of more than 100 categories. When the application system (including USB flash drive identification device or SD card identification device) leaves the factory, it is necessary to perform functional tests on external storage devices (U disk and SD card) of different brands and capacities to ensure the compatibility of the application system with various external storage devices, so as to avoid problems that affect the user experience such as the inability to identify external storage devices, resulting in the inability to play audio and video and pictures, poor sound quality, etc.

[0003] In the prior art, the compatibility test of external storage devices in vehicle-mounted application systems is mainly carried out by manually plugging and unplugging external storage devices to check various functions, including whether the external storage device can be identified, whether the playback, pause, fast forward and rewind functions are normal, whether there is noise during playback, and more than ten other test items, and the tester is also required to manually record each test result of each connected external storage device into an Excel table. If a vehicle-mounted application system needs to perform compatibility tests based on mainstream external storage devices of different brands and capacities, the testing process will be repetitive and cumbersome, and the efficiency will be extremely low. In addition, when product defects occur during prototype testing, it is very easy to miss key logs and phenomenon videos due to manual capture of product analysis logs and video recordings, delaying the technical staff's analysis opportunities. Furthermore, although the final external storage device compatibility report includes successful test items and failed test items for each external storage device, it still needs to be manually searched and filled in, which is not intuitive enough. At the same time, many external storage device defects do not exist only in individuals. It is possible that the same type of external storage devices have such defects. The existing manual recording method of Excel tables tends to analyze individual external storage devices, which cannot effectively analyze the distribution pattern of defects, and is not conducive to the overall defect analysis of external storage devices and the correlation between brands and capacities.

[0041] The second image acquisition device 61 is a monitoring camera facing the functional display interface of the vehicle-mounted application system 0. The second image acquisition device 61 is also used to capture a static picture of the functional display interface and record a dynamic video when the test fails.

[0042] The sound acquisition device 62 includes at least one sound sensor, and the sound sensor is used to acquire the audio waveform output by the speaker of the vehicle-mounted application system 0.

[0043] The PC host computer 2 is provided with a remote communication module for sending test information and reminder information to the bound remote client according to the test result, and outputting the test report to the remote client or the local client at the request of the remote client or the local client.

[0044] The external storage device includes a USB flash drive and an SD card, as well as a mobile phone terminal and a personal computer with data storage function; the vehicle-mounted application system 0 is a vehicle-mounted entertainment audio navigation system.

[0045] Taking the external storage device as a USB flash drive as an example, the specific working principle of the test device is as follows:

[0046] First, a comparison template database is pre-set, and the standard response information (including display interface and audio playback) of the vehicle application system 0 connected to the external storage device is set as a comparison template, and the corresponding similarity threshold is set and stored in the comparison template database. The PC host computer 2 pre-writes test cases through the built-in programmable logic controller.

[0047] All the USB flash drives 7 to be tested are assembled in sequence on the tail end of the male socket 55 on the large gear 53 of the turntable actuator 5; the tail end of the male socket 55 can also be connected to a USB data cable to read the internal storage information of other storable devices through the USB data cable, and the other storable devices include but are not limited to mobile phones and personal computers; connect the vehicle-mounted application system 0 currently being tested and the female socket 52.

[0048] The PC host computer 2 drives the first image acquisition device 4 and the motor drive device 3 at the same time, controls the probe camera 42 to be powered on and enter the monitoring mode, controls the second drive motor 32 to drive the large gear 53 to rotate a certain angle, so that the male socket 55 of this timing sequence reaches the test station facing the female socket 52, and then controls the first drive motor 31 to move forward, driving the female socket 52 on the slider 51 to connect to the male socket 55, that is, the U disk 7 to be tested is connected to the vehicle application system 0. During this period, the probe camera 42 continuously monitors the U disk 7 access status and rotation action of the male socket 55 of this timing sequence, as well as the forward action of the female socket 52, and feeds back to the PC host computer 2 in real time.

[0049] The vehicle-mounted application system 0 completes the information reading and application operation of the U disk 7 according to the preset test case. At this time, the PC host computer 2 controls the second image acquisition device 61 and the sound acquisition device 62 to be powered on, and respectively controls the monitoring camera and the sound sensor to regularly acquire the function display screen and the audio output waveform when the vehicle-mounted application system 0 runs the test case. Finally, the PC host computer 2 uses the image template matching algorithm to match the function display screen according to the preset comparison template, obtains the comparison similarity, and determines the image comparison result according to the similarity threshold; if the comparison similarity is less than the similarity threshold, the test is judged to be unsuccessful, otherwise the test is passed. The PC host computer 2 also uses the signal curve value frequency detection algorithm to calculate the signal amplitude and frequency tolerance of the audio output waveform, and compares them with the standard preset playback signal amplitude and preset frequency tolerance to obtain the audio comparison result; only when the signal amplitude and frequency tolerance of the audio output waveform are not less than the standard preset playback signal amplitude and frequency tolerance, the test is passed, otherwise the test is unsuccessful.

[0050] If both the image comparison results and the audio comparison results pass the test, it means that the timing test passes and the vehicle-mounted application system 0 is controlled to continue running the test case; otherwise, it means that the timing test fails, and the vehicle-mounted application system 0 is controlled to stop running, record the current log timestamp, control the surveillance camera to capture the test scene picture and intercept the test video and audio of the surveillance camera in the preset time period, and send the comparison results and reminder information to the bound remote client, such as the user's mobile terminal.

[0051] The PC host computer 2 also organizes the test results, and generates a corresponding test report in the form of a file (such as an Excel table) by combining the above response information, comparison results and test data.

[0052] The test report includes the project test information, software version, test location, test time, test results, basic information of the external storage device, product log, product function display interface picture and test video of the vehicle-mounted application system 0. Finally, it is determined whether the vehicle-mounted application system 0 has completed the docking test with all the USB disks 7 to be tested on the large gear 53. If so, the test is terminated. If not, the test work of the next time sequence is entered.

[0053] When the test of this sequence is finished, the first drive motor 31 is controlled to drive the female socket 52 to retreat, disconnecting the vehicle-mounted application system 0 from the USB disk 7 to be tested in this sequence, and entering the test of the next sequence until the vehicle-mounted application system 0 and all the USB disks 7 to be tested on the turntable execution device 5 have completed the docking test, thus ending this test.

[0054] The PC host computer 2 outputs the test report to the remote client or the local client at the request of the remote client or the local client.

[0055] The embodiment of the present invention provides an automated testing device for the compatibility of an on-board application system, which uses a motor drive device 3 and a turntable execution device 5 to establish an automatic docking mechanism with the on-board application system, drives the USB disk 7 to be tested on the large gear 53 to reach the docking position through the gear transmission of the rotating motor, and also uses a linear motor to push the slider 51 to perform linear motion to control the female socket connected to the on-board application system 0 and the male socket connected to the USB disk 7 to be tested, thereby realizing the automated connection and docking of the on-board application system 0 with multiple USB disks 7 to be tested; the device also uses the information interaction of the PC host computer 2 to realize the remote monitoring of the compatibility test of the on-board application system.
