Embodiment Construction
[0030] Such as figure 1 As shown, the instrument pressure test system of an embodiment of the present invention is used for pressure testing the instrument with a display screen. The instrument with a display screen can be a combination instrument with a display screen or a full LCD screen instrument. In the embodiment, the instrument to be tested is a full LCD instrument.
[0031] The instrument pressure testing system includes a test host 2 and an image acquisition device connected to the test host 2 . The image acquisition device is placed at a position capable of collecting the display screen of the full LCD screen instrument, and the test host 2 is connected to the full LCD screen instrument through a debugger, a serial port, and a CAN bus.
[0032] The image acquisition device is used to collect images of the display screen 1 of the full LCD instrument during the stress test and transmit the collected images to the test host 2. The image acquisition device can be a came...

The present invention provides an instrument pressure test system, which is used to perform pressure test on an instrument with a display screen, including a test host and an image acquisition device, and the image acquisition device is used to collect images of the display screen during the stress test and transmit the collected images To the test host, the test host is used to run the instrument stress test script to send the effective input data of the test case to the instrument, save the image and associate the image with the corresponding switching of the display screen, so as to identify the display defect of the instrument. The invention also provides an instrument pressure testing method. The instrument pressure test system and the instrument pressure test method provided by the present invention collect and store images and switch the associated images to corresponding display screens during the pressure test, quickly locate the display defect of the instrument, so as to quickly repair the display problem of the instrument, This will not only reduce customer complaints about instrument quality, but also reduce the manpower and material resources required to update instrument software.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an instrument pressure testing system and an instrument pressure testing method. Background technique [0002] With the rapid development of automotive technology, automotive instrumentation is also developing towards larger and clearer 3.5-inch, 7-inch, and even 12.3 full-size display instruments. Instruments with display screens control the display of the instrument through software. [0003] In addition to completing the functional test before the software freezes, each car instrument needs to do a lot of stress tests to verify the reliability of the software, so as to avoid the frequent operation and switching of the instrument in actual use, which will cause the MCU chip of the instrument to be in a high load state. Abnormal display problems, such as some defects in software architecture design and hardware circuit design, or there may be a certain time gap when the display data i...
