Vehicle multimedia automatic test system

Vehicle multimedia automatic test system is a kind of automatic test solution established for high-precision test of various functional indexes of auto audio. Based on the long-term interests of customers, the scheme has flexible hardware platform and standardized general software platform, which makes the automatic test system of customers easy to expand, maintain and manage. At the same time, because its hardware platform is not limited by the equipment brand and model, it can quickly establish an automatic test system with the same accuracy, high stability and high efficiency as the existing equipment based on the existing equipment of customers.

System features

Stable:The equipment structure is clear, and the control interface is standard and reliable.

Simple: Reduce 50% wiring quantity by using integrated controller

Easy to expand:Open architecture, function modules can be added or reduced as needed at any time

Easy maintenance:Standardized interface and general wire are adopted for the equipment, which is convenient for maintenance and replacement.

Software features

The test software platform is developed by Lab View of Ni, with independent intellectual property rights. It is specially used for vehicle multimedia testing, with the following characteristics：

Stable:The test platform is independently developed by LabVIEW and has been used by many users for a long time.

Easy to use:The operator only needs to scan the bar code on the product, and all other processes are completed by software. In some actions that must be manually completed by people, such as putting and taking dishes, the software will prompt the operation and precautions with words and sounds;

friendly interface:All test states are clear at a glance, real-time display of operation state, items under test, signal waveform, test results, test abnormal items, etc;

Data storage: all test data are saved locally in real time, and can be saved by remote network server;

Waveform monitoring: real-time monitoring signal waveform;

Strong expansibility: in addition to modifying test parameters on the test software platform, users can easily add new types of test models, and select different test items for testing according to their needs.
