The invention provides an electromagnetic compatibility vehicle-mounted transmitter anti-interference test monitoring system and a test method. The system comprises a vehicle-mounted transmitter anti-interference test environment system and an auxiliary monitoring system which are connected. The vehicle-mounted transmitter anti-interference test environment system comprises anti-interference test equipment, a test antenna and a tested vehicle. The anti-interference test equipment comprises a radio frequency signal generator, a power amplifier and a directional coupler; the auxiliary monitoring system comprises an audio and video monitoring system, a network communication monitoring system and an electrical parameter monitoring system. According to the electromagnetic compatibility vehicle-mounted transmitter anti-interference test monitoring system, the working phenomenon of the tested vehicle and the message condition of vehicle network communication can be monitored and recorded in real time during the vehicle-mounted transmitter anti-interference test, and the abnormal working state, which cannot be observed subjectively, of an electric device can be accurately found.
Description
technical field [0001] The invention discloses an electromagnetic compatibility vehicle-mounted transmitter anti-disturbance test monitoring system and a test method, belonging to the technical field of vehicle tests. Background technique [0002] In recent years, with the continuous improvement of automobile technology, more and more multifunctional electronic devices are used in automobiles, and the electromagnetic environment in which automobile electrical systems are located is becoming more and more complex. The existing vehicle transmitter anti-jamming test monitoring system is: during the test process, the appearance of the vehicle working condition is monitored through video equipment. [0003] The current anti-jamming test of the vehicle EMC vehicle transmitter is not carried out at the same time as the vehicle network communication monitoring and electrical parameter monitoring, and there are the following deficiencies: [0004] (1) Subjectivity. The anti-interfe...
