基于HPVEE的木质材料电磁波效能测试系统的设计与实现

Design and application of electromagnetic effectiveness measuring system for wood materials based on HP VEE

有害电磁波已被公认为是污染源之一,因此,在建筑、装修、家具等木质材料中,电磁波屏蔽越来越受到高度重视,并已逐渐成为一项重要的检测指标。本文介绍了在HPVEE开发环境下,通过GPIB接口,用DirectI/O组件开发的木质材料电磁波效能软件测试系统。该系统实现了检测设备、频谱分析仪和计算机三者一体的数据实时采集、存储和分析,及对木质材料的电磁效能测试。该系统将对木质材料电磁波屏蔽指标的理论研究、木质材料电磁屏蔽标准的制定有一定的参考价值。

Under the HP VEE developing environment and by the GPIB interface and Direct I/O component, the software of wood-based materials electromagnetic efficacy testing system was exploited, and the real-time data can be stored and analyzed through connecting testing instrument, EMC and PC. By the testing software the instrument can be controlled and the wood-based materials electromagnetic efficacy can be given. So we can get the better instrument-virtual instrument.
