A comprehensive test device and test method for a vehicle-mounted display

Abstract

The present invention discloses a vehicle-borne display device comprehensive testing device which comprises a testing master control machine for managing a test case and analyzing a testing result, a man-machine interface testing module which is connected to the testing master control machine, simulates a man-machine interaction screen touch operation according to the test case, obtains the output image of a tested display device, and analyzes the man-machine interaction display function and reliability of the tested display device, a communication interface testing module which is connected to the testing master control machine, monitors the operation state of the tested display device and analyzes the communication reliability and stability of the tested display device, and the tested display device which is connected to the man-machine interface testing module and the communication interface testing module. The invention also discloses a testing method, according to testing requirements, a code white box test, a man-machine interaction test and a communication interaction test are executed, the testing result data is analyzed, and a testing report is outputted. Complex communication and electrical environments can be simulated, the degree of automation is high, and the test coverage is wide.

Description

technical field [0001] The invention relates to the technical field of testing vehicle-mounted displays, in particular to a comprehensive testing device and a testing method for vehicle-mounted displays. Background technique [0002] The on-board display products used in the field of rail transit are the man-machine interface components of various control and information systems. Status display, train safety monitoring device display and engineering vehicle network system status display and other types. Vehicle display software usually runs on an embedded operating system with limited operating environment resources. As a man-machine interface, or even the only interface, the function and performance level of the display software system has a huge impact on the user's use. [0003] The hardware platform of the car display usually includes rated power supply, LCD screen, touch screen, communication interface (Ethernet / MVB / CAN / RS422 / RS232 / RS485 / USB, etc.), keyboard interface...

AI Technical Summary

Problems solved by technology

[0005] The main problems are as follows: 1. The test coverage is narrow, and white box testing at the code level is not involved, so it cannot effectively check the code quality and dig out potential safety hazards caused by code problems; 2. For the human-machine interface test, manually click on the display touch screen and panel Buttons, while human eyes check the display response, low efficiency, time-consuming and labor-intensive, the test is highly subjective, too dependent on the technical quality of the tester, and mainly functional testing, it is difficult to achieve high-intensity operating performance status detection of the tested display; 3. For the communication interface test, compile the application layer test script, and compare the data consistency between the receiver and sender of the tested display to judge whether the communication is normal. 4. The test cases are scattered and there is no unified test management environment for sorting and scheduling. It is often what the testers think of and where they measure. The amount of test data is large but cannot be efficiently organized, which requires a lot of consumption of human resources to identify and analyze
