摘要
针对目前故障仿真注入过程中存在着效率低、自动化程度低等问题,设计了基于PSpice仿真环境的故障自动注入平台。在该平台中对常见的十几种故障模式在PSpice中进行了建模,分别封装在3类故障库中,为故障的注入提供了便捷清晰的路径。并深入研究了PSpice仿真器的结构和电路描述语言,采用面向对象的思想编写了可对PSpice模拟电路进行分析的解析模块,实现将指定故障注入到目标电路的故障自动注入过程,在一定程度上改进了故障注入繁琐和不智能问题。经过实验验证了该设计的正确性与有效性。
For solving the problems of the low efficiency and low degree of automation in fault simulation injection, this paper designed a fault injection automatic platform based on PSpice. The platform builds a dozen or more fault models in PSpice and packages them in three different types of fault libraries, and provides clear path for injecting. And it then penetratingly researches the structure and the circuit description language of PSpice simulator and compiles the analysis module to analyze PSpice artificial circuit using object-oriented technique, and achieves the automatic progress for injecting the specified faults to objective circuit. At last, the whole project is proved to be correct and effective through the experiment results.
