Abstract

The invention provides an aging test method and device for vehicle-mounted multimedia equipment, and the method comprises the steps: setting a start identification and an end identification in test multimedia information according to a preset marking strategy; controlling the test multimedia information to be played from the start identifier, and ending the playing of the test multimedia information when detecting that the current multimedia information contains the end identifier; and controlling the test multimedia information to be played from the start identifier so as to enter the next playing of the test multimedia information, and stopping playing the test multimedia information until the sum of the playing durations of the test multimedia information for multiple times is greater than or equal to the preset test duration, thereby realizing the aging test of the multimedia equipment. Therefore, based on the setting of the start identifier and the end identifier in the test multimedia information, the determination of the playing start time and the playing end time of the multimedia test information is realized on a software level, and a power amplifier component does not need to be set to provide the playing start time and the playing end time, so that the test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia equipment testing, in particular to a method and device for aging testing of vehicle multimedia equipment. Background technique [0002] With the development of computer technology, the application of multimedia equipment in vehicles is becoming more and more extensive. Among them, in order to ensure the service quality of vehicle multimedia equipment, testing of multimedia equipment before leaving the factory has become a requirement, for example, aging testing of vehicle multimedia equipment. [0003] In related technologies, the aging test of multimedia equipment is to run an installation package to continuously play the test multimedia information for several hours. Since it is unrealistic to select a multimedia information that can be continuously played for several hours, loop playback is usually used. A section of test multimedia information is used to meet the aging test of mult...
