基于虚拟仪器技术的故障诊断专家系统的实现

摘要

With the development of computer technology , artificial intelligence technology become more and more important in testing domain. And it will be the direction that expert system technology is used into testing system. Through introducing the theory of expert systems, the feasibility of technology inducting expert systems to measuring was introduced. And the software design of test systems based on VI and expert systems based on rules was introduced separately. The realization of failure diagnoses and real-time failure diagnoses was produced. After using the software, it is thought that the expert system will redound to realize the intelligent failure diagnoses and enhance the intelligent grade of test technology.%随着计算机技术的发展,智能技术在测试领域显得越来越重要,在传统的测试系统中使用专家系统技术成为测试系统的发展趋势;文章通过对专家系统原理的介绍,提出了将专家系统技术引入测试领域的可行性,并分别介绍了基于虚拟仪器的测试系统软件设计方法和基于规则的专家系统软件设计方法,并给出了故障诊断专家系统的实现方法和实时故障专家系统的设计方案;经使用后,认为专家系统技术将有助于智能化故障诊断的实现,并且可提高测试技术的智能化程度.
