摘要
构建EMC自动测试系统时,软件主要用于描述测试项的数据处理算法和仪器程控方法。由于数据处理算法大多是由相关标准规定好的,因此,开发EMC自动测试系统的核心内容是设计程控仪器的配置策略,以提高软件的通用性和仪器硬件的可互换性。提出了基于IVI-COM技术的仪器驱动模型,阐述了仪器驱动组件的设计思路,以及在Visual C++环境下的实现方法,通过实例分析,验证了该方法的可行性和有效性。实验结果表明,增加EMC测试项时,简化了对仪器控制部分的程序设计,且更换同类仪器也无需改动EMC测试软件,降低了系统在使用寿命周期的维护费用,有效保护了用户投资。
EMC test software is used to realize instrument control methods and various data processing algorithms. Due to data processing algorithm is defined by related standards, so the core task of developing EMC test software is to design configuration strategy to improve the software universality and instrument interchangeability. This paper presents an instrument driving method based on IVI-COM technology, introduces the design method for instrument driving components and the development method under Visual C ++ programming environment. An example is used to verify the availability based on IVI-COM technology to realize instrument interchangeability for EMC test. Experimental results show that when a new test item is added, there is no need to consider how to control the instrument; and instrument can be replaced by other one without having to modify EMC test software. So, the maintenance cost of the system is reduced, and user investment is protected.
