摘要
从数字系统故障检测的普遍性出发,在MaxplusII/Quartus环境中运用CPLD设计了其ASΙC,用开关DG1A05BW完成各引线的通用控制电路,借助Delphi强大的数据处理功能实现测试数据库的自动生成、图形化人格交互界面及故障测试,用后驱动技术提高故障定位能力,在PC机控制下虚拟地实现数字逻辑故障通用诊断系统。实验表明:系统具有硬件通用性强、编程灵活、扩展性好等特点。重点介绍其通用控制电路、CPLD设计及故障字典生成方法。
A virtual common system diagnosing logical trouble was presented under the control of PC from the universality of digital diagnosing system,in which the ASIC was realized with CPLD in the Maxplus II/Quartus,switch DG1A05BW used to achieve common control circuit of each line,Delphi designed to fulfil auto-creating of testing data base,man-machine interface,testing trouble by means of powerful function of processing of date,Back Driving technology used for locating trouble further.Experiments showed system had strong common in handware,flexible programming,best extension,etc.The design method of common control circuit and CPLD,generic trouble dictionary were mainly introduced.
