The Testing Data Analysis and Research from Disturbances by Conduction and Coupling of Beidou Navigational Terminal

Abstract:

Aiming at the status quo of Beidou navigational system used in automobile, this paper puts forward a testing project based on ISO7637-1,2,3 standard road vehicles-electric disturbances by conduction and coupling, and tests the provided specimen at first. Then during the test process, according to the different requirement of specimen performance, refer to the reference standard, the testing pulse parameters are set. At last, according as the collected data and information, result of testing is analyzed and researched, and protected circuit, filtering circuit and power supply input circuit are designed to the problems of specimen. The analysis of testing result denotes that the EMS design of Beidou navigational terminal has some abilities, the report of testing result analysis has great modeled behaviors in standard establishment and product popularization of Beidou navigational terminal.
