Embodiment Construction
[0030] like 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 camera ...

The invention provides an instrument pressure test system, which is used for performing pressure testing on an instrument with a display screen. The system comprises a test host and an image collection apparatus; the image collection apparatus is used for collecting an image of the display screen in the pressure test process and transmitting the collected image to the test host; and the test hostis used for running an instrument pressure test script, sending effective input data of a test case to the instrument, storing the image and associating the image to corresponding display image switching, thereby identifying display defects of the instrument. The invention furthermore provides an instrument pressure test method. According to the instrument pressure test system and the instrument pressure test method provided by the invention, in the pressure test process, the image is collected and stored and is associated to the corresponding display image switching, and the display defects of the instrument are quickly located for quickly solving the display problem of the instrument, so that the complaints of customers to instrument quality can be reduced and the manpower and material resources for updating instrument software can be reduced.
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...
