Vehicle-mounted display automatic test device and test method

Abstract

The invention discloses a vehicle-mounted display automatic test device which comprises an upper computer, a visual system, a four-axis robot system, an audio analysis system, a communication test system and a visual and key calibration system, and can meet the comprehensive test requirements of the vehicle-mounted display. The invention relates to a vehicle-mounted display automatic test method, which can automatically test one or more of communication, data transmission, a screen, keys, light sensing and audio of the vehicle-mounted display according to test requirements, and perform corresponding test analysis. The vehicle-mounted display automatic test device and the test method have the advantages of a wide test coverage, high test efficiency, a high automation degree, a reliable test result and the like, can meet the actual production test requirements of the vehicle-mounted display, are high in practicability, and are beneficial to an industrial application.

Description

technical field [0001] The invention relates to the technical field of on-board display testing on trains, in particular to an automatic testing device and a testing method for on-board 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. They are responsible for controlling the train in the form of text, graphics, and sound, displaying status information and necessary man-machine operations. Common on-board displays include train network system status displays, train safety monitoring device displays, and engineering vehicle network system status displays. [0003] Vehicle display software usually runs on an embedded operating system with limited operating environment resources. As the man-machine interface, or even the only interface, the software system functions and performance levels of the display have a huge impact on the user experi...

AI Technical Summary

Problems solved by technology

In the process of manual testing, due to the differences in the action strength, visual sensitivity and auditory sensitivity of different operators, there are deviations in the stroke and feedback force of the keys, and it is easy to miss the bright spots and dead spots of the screen when visually checking. And there are inconsistencies in the perception of the size, sound pressure and frequency of the sound of the monitor

In the end, the data collection of the display test process is incomplete, which leads to traceability problems

Especially at the customer's operation site, due to the differentiated performance of the operators, it is easy to cause customer dissatisfaction

[0005] In summary, in the existing vehicle-mounted display test methods, the test and analysis of buttons, screens, sounds, etc. are all tested and analyzed by a separate workstation. Although this separate test method has a wide range of applications and a simple structure , The advantages of convenient equipment, but there is also an extremely obvious disadvantage: the performance of the vehicle display cannot be comprehensively tested, and there are test blind spots
