【摘要】：随着科学技术的飞速发展,车载电子信息系统中各类各样的电子通信设备也越来越多,如通信设备、导航设备以及基于计算机网络的各种信息系统等,其发生电磁干扰的可能性也被大大提高。加上一些自然因素,致使车载电子信息系统所处的电磁环境越来越复杂。在严峻电磁环境影响下,车载电子信息系统的正常工作状态受到很大威胁,增加可能的干扰预测,提高设计能力,尽量避免电磁兼容问题,并加强车载电子信息系统的电磁环境适应性已经成为普遍关注的问题。因此,本文以车载电子信息系统为研究对象,以其电磁环境适应性为评估目的,建立了电磁环境适应性评估指标体系,实现了系统环境适应性的综合评估。本文首先分析了影响系统电磁环境适应性的关键要素,从干扰源、耦合途径以及敏感设备三方面出发进行了分析,研究了各要素之间的相互关联关系,依据体系构建原则构建了完整的车载电子信息系统电磁环境适应性评估指标体系。然后提出了评估的普适模型,根据所建立指标体系的网络分层化特点,选取ANP方法进行权重获取,并基于传统ANP方法的缺陷,引入DEMATEL方法对其进行了改进,选用改进后的ANP-TOPSIS方法对系统电磁环境适应性进行综合评估。最后基于所建立的指标体系与评估方法,依据多属性决策理论,通过实例验证了文中指标体系与评估方法的实用性与可行性。
[Abstract]:With the rapid development of science and technology, electronic communications equipment, all kinds of more and more vehicle electronic information systems, such as communication equipment, navigation equipment and computer network based on various information systems, the possibility of the occurrence of electromagnetic interference has also been greatly improved. Some natural factors, resulting in vehicle electronic information system in which the electromagnetic the environment is more and more complicated. In the severe electromagnetic environment under the influence of the normal working state of vehicle electronic information system has been a great threat to increase the possible interference prediction, enhance the design ability, avoid electromagnetic compatibility problems, and strengthen the vehicle electronic information system of electromagnetic environment adaptability has become a widespread concern. Therefore, the vehicle electronic information system as the research object, with its electromagnetic environment adaptability for assessment purposes, establish the electromagnetic environment adaptability evaluation index system. The comprehensive evaluation system of environmental adaptability. This paper analyzes the key factors influencing the system of electromagnetic environment adaptability, from the source of interference, and the coupling way of sensitive equipment in three aspects were analyzed to study the mutual relationship between the various elements, on the basis of system construction principles, electromagnetic environment adaptability of vehicle electronic information system integrity assessment and then put forward the evaluation index system. The universal model, according to the characteristics of the network hierarchical index system, selects the ANP method for weight gain, and the traditional ANP method based on the lack of depression, DEMATEL method is introduced to improve it, using the improved ANP-TOPSIS method to carry out a comprehensive assessment system of electromagnetic environment adaptability. Finally based on the evaluation index system and method are established, based on multi-attribute decision theory is verified by an example of evaluation index system and the The practicability and feasibility of the method.
