【摘要】：经常性的现场测试是掌握电子系统实时指标和电磁兼容状况的基本手段。针对电磁兼容测试数据较多但应用不充足的现状,提出了电磁兼容模型综合的概念,结合电磁兼容原理,实现了运用数理统计方法和人工神经网络技术对电磁测量结果进行数据挖掘,对统计分析方法进行了实用性设计,研究了神经网络训练方法的实用性及学习率确定方法。电磁兼容模型综合可建立或修正模型,归纳综合设备电磁参数及系统和平台电磁兼容性能变化规律,实现电磁兼容信息综合与状态预测,为增强系统电磁兼容针对性测试、主动管理和预知性维护与保障提供技术手段。
[Abstract]:Regular field testing is the basic means to master the real-time indicators and EMC status of electronic systems. Aiming at the current situation of EMC testing data but insufficient application, the concept of EMC model synthesis is put forward. Combined with the principle of electromagnetic compatibility, the data mining of electromagnetic measurement results is realized by using mathematical statistics method and artificial neural network technology, and the practical design of statistical analysis method is carried out. The practicability of neural network training method and the method of determining the learning rate are studied. The electromagnetic compatibility model synthesis can be established or modified, and the electromagnetic parameters of the integrated equipment and the variation rule of the electromagnetic compatibility performance of the system and platform are summarized. The realization of EMC information synthesis and state prediction provides technical means for enhancing EMC pertinence testing, active management and predictive maintenance and guarantee.
