车载紧急呼叫系统整车触发特性关键测试技术和方法研究

从车载紧急呼叫系统整车触发特性的关键测试技术出发,分析了车载紧急呼叫系统整车触发特性关键的测试方法。针对车载紧急呼叫系统最为关键的整车触发特性测试复杂的测试环境,提出了一套完整的测试技术和测试方法,提高了测试系统的可靠性,大大降低了由于信号不稳定导致的试验失败的风险。最后通过试验对测试方法进行了论证,验证了测试方法的有效性。由于国内车载紧急呼叫技术还处于起步阶段,因此本文研究的车载紧急呼叫系统整车触发特性的测试技术和方法,可以为国内企业在研发过程中提供试验验证和指导,可以为国内企业进军欧盟市场和海关联盟等国外市场提供本地化的认证和测试,同时可为中国的强制性标准提供有力的数据和技术支撑。

Research on Key Test Techniques and Methods for Vehicle Triggering Characteristics of In-Vehicle Emergency Call System

From the key test technology of the vehicle trigger characteristics of the in-vehicle emergency call system,we analyzed the key test methods of the vehicle trigger characteristics of the vehicle emergency call system.For the most important vehicle trigger characteristic test of the in-vehicle emergency call system,a complete set of test techniques and test methods are proposed for complex test environment to improve the reliability of the test system,which can greatly reduce the risk of test failure due to signal instability.Finally,the test method was demonstrated through experiments,and test method was verified.Since the domestic vehicle emergency call technology is still in its infancy,the testing technology and method of the vehicle trigger characteristics of the in-vehicle emergency call system studied in this article can provide verification test and guidance for domestic enterprises in the research and development process.It can provide localized certification and testing for domestic enterprises to export to foreign markets such as the Customs Union and the EU market.And at the same time it can provide strong support in data and technology for China's mandatory standards.
