【摘要】 针对北斗导航系统在车载终端方面的应用现状,论文首先提出了一种基于车辆电子设备电源线/信号线瞬态脉冲抗干扰试验标准ISO7637-1,2,3标准的测试方案,对所提供的测试样品进行传导抗干扰测试。然后在测试过程中,根据样品性能的不同要求,参照参考标准,配置不同的测试脉冲参数。最后依据所采集的测试数据和信息,对测试结果进行分析研究,并对样品所出现的问题进行保护电路、滤波电路和电源接入电路设计。测试结果分析表明:北斗车载导航终端在电磁兼容传导抗干扰性设计方面已具有一定的水平,测试的数据分析报告对北斗导航终端测试标准和规范的制定及产品的推广有非常大的示范作用。更多还原

【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.更多还原
