介绍了自动测试系统的发展趋势,以及ATS开发平台Chroma8000系统的特点。阐述了OBCM的关键电气性能指标和测试方法。使用指数平均和移动平均的数据采集方法创建了基于Chroma8000的OBCM自动测试系统,解决了自动测试系统测试效率低、量测误差大的问题。工厂端大批量产品的测试结果证明,该系统是一个可实际使用的精确高效的自动测试系统。
The development trend of automatic test system and the characteristics of Chroma8000 system of ATS development platform are introduced. The key electrical performance indicators and test methods of OBCM are described. Using the exponential averaging and moving average data acquisition method, an OBCM automatic test system based on Chroma8000 is created, which solves the problems of low test efficiency and large measurement error of automatic test system. The test results of large quantities of products at the factory end prove that the system is an accurate and highly efficient automatic test system that can be actually used.
