Embodiment 1

[0026] Such as figure 1 As shown, the present invention provides a visual durability instrument test system for simulating real car keys, which is characterized in that it includes a main control module: used to control the work of other modules and compare and analyze the data transmitted from other modules, and output the test Report; data transmission module: including the CAN bus board for transmitting bus data to the test equipment and the current acquisition board for transmitting current signals to the test equipment, the CAN bus board and the current acquisition board are all Connected with the device under test for transmitting detection data to the device under test; visual detection module: including an industrial camera, the camera of the industrial camera is set relative to the display module of the device under test for real-time shooting of the operation of the device under test; Power module: It is used to supply power to the entire test system and the equipmen...

Embodiment 2

[0029] Based on Embodiment 1, the present invention also provides a method for testing a visual durability meter that simulates a real car key starting, including the following steps: S1: perform a test on the test machine and the device to be tested, and perform parameter presets; S2: the test machine will test The data is transmitted to the device under test, and the data is displayed on the display screen of the device under test; S3: the visual detection module captures the display status of the device under test, and transmits the image to be tested to the main control module; S4: the main control module will The image to be tested is transmitted from the visual transmission module, and the image is obtained for analysis to find out the ROI information and icon name; S5: Access the database, and obtain the detection icon template through the ROI information and icon name; S6: Compare the detection icon template with the image to be tested Yes; if the comparison result is a...

Embodiment 3

[0033] Based on Embodiment 2, further, in the step S11, the database generation includes the following steps: S111: Initialize the visual system variables; S112: Drive the camera to capture the working image of the device under test, and obtain the ROI position information of the image; S113: Determine whether It is necessary to save the icon template and ROI coordinate data in the ROI. If it needs to be saved, it will be stored in the specified data calibration storage path according to the name specified by the user; S114: Determine whether the icon and ROI coordinate data in the currently selected ROI need to be deleted. If it needs to be saved , delete the data from the specified data standard storage path. S115: Write test execution instruction data and result inspection data corresponding to the icon information, and generate a test script. S115: Summarize all icon information and test scripts, and generate a database.

[0034] Further, the test data includes at least on...

Abstract

The invention relates a testing system for an instrument for simulating startup visual durability of a real car key. The testing system comprises a main control module which comprises a CPU and a peripheral circuit of the CPU and is used for controlling other modules to work, comparing and analyzing data transmitted by other modules and outputting a test report, a data transmitting module which isused for transmitting detection data to a to-be-detected device, a visual detecting module which is used for taking pictures of the running conditions of the to-be-detected device in real time, and apower module which is used for supplying power to the whole testing system and the to-be-detected device. The testing system has the advantages that the testing efficiency is greatly improved and manpower resources are released by means of automatic testing, the advantageous help is provided for reappearing, analyzing, solving and verifying of the problem by means of the site protection and process data recording, pressure durability testing features not limited in frequency and time are achieved when the testing of various user scenes of a real car is simulated, and the convenient testing environment is provided for testing and verifying the accidental and small-probability problem.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a visual durability meter test system for simulating real car keys to start. Background technique [0002] Before the R&D and mass production of automotive instrument accessories, a large number of actual vehicle tests are required, especially for the scene test of the user's daily operation, such as the frequent operation of the ignition key and the durability test of dynamic driving. In the actual road test, the number of operations performed by the test is often very small, and some occasional probabilistic problems, such as restarting, crashes, blurred screens, and black screens, are difficult to find in limited road tests. Even if the phenomenon disappears after being discovered for a while, the scene cannot be protected, and the phenomenon is difficult to reproduce, which brings great challenges to the solution of the problem. [0003] The traditional scene ve...
