摘要
针对手动电磁兼容测试系统速度慢的问题,设计了一套基于LabVIEW软件开发平台和GPIB总线结构的电磁兼容自动测试系统,将LabVIEW软件开发平台以及小波分析理论应用于电磁兼容测试,实现了信号发生、监控、分析、记录等功能。解决了函数的快速收敛性、电磁兼容测试系统硬件的控制、设计的周密性、软件的兼容性等难点和关键技术,开发了电磁兼容自动测试系统。与目前使用的普通台式仪器的手动测试相比,该系统大大提高了测试速度与精度,并具有良好的扩展性。
According to the problem that the speed of electromagnetic compatibility（EMC） manual system is slow, an automatic testing system is designed for electrical power wire conducted emission based on general- purpose interface bus （GPIB） and LabVIEW, which actualizes a series of functions, such as signal generating, monitoring, analyzing and showing. It solves the hard problems of the electromagnetic compati- bility testing system and key techniques such as hardware＇ s controlling, algorithm＇ s fast convergence, software＇ compatibility. It is the first time of applying LabVIEW and wavelet analysis theory to the EMC automatic system. Comparing with the other traditional apparatuses and the manual testing, the system improves the test efficiency and has good extensibility.
