Electromagnetic compatibility test system of vehicle-mounted entertainment system

Abstract

The invention provides an electromagnetic compatibility test system of a vehicle-mounted entertainment system. The electromagnetic compatibility test system comprises an entertainment system host, a driving module and a monitoring module. The load simulator is used for simulating a CAN loop to send a CAN signal to the entertainment system host and receiving a feedback CAN signal sent by the entertainment system host, and the CAN signal is a first preset function signal; the entertainment system host is used for receiving the CAN signal sent by the load simulator and executing a first preset function according to the CAN signal; the monitoring camera and the microphone are used for collecting video information and audio information of the entertainment system host respectively, and the display and signal processing unit is used for analyzing, processing and displaying the received audio and video information and judging whether the entertainment system host has electromagnetic compatibility abnormity or not in combination with a feedback CAN signal sent by the entertainment system host. The functions of the entertainment system host can be effectively tested, and the test result can be conveniently and accurately obtained through data analysis and CAN signal feedback.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electromagnetic compatibility testing system for a vehicle entertainment system. Background technique [0002] With the rapid development of the automobile industry, the trend of networking and intelligence is inseparable from the in-vehicle entertainment system. Car entertainment systems are becoming more and more complex, including multiple functional modules, mainly including Bluetooth, radio, mobile phone interconnection, navigation, audio and video playback, video and other functions. Therefore, the corresponding EMC (electromagnetic compatibility) testing is also becoming more and more complicated. [0003] At present, the electromagnetic compatibility of the car entertainment system is usually to monitor the functions of the entertainment system manually and obtain the monitoring results. If there is a broken sound, this test method is highly subjective and lacks the necessa...
