电路仿真系统中消息驱动机制的研究

Investigation of message-driven method for circuit simulation training system

在目前推出的汽车电路仿真培训系统中,无法对插接件的工作状态进行模拟,同时系统固定的运行流程给学员的操作带来限制。针对这些问题,以桑塔纳轿车电路仿真系统的设计为背景,确定了电路矢量图形系统中边数组的存储结构,在此基础上提出边数组元素随用户操作实时发生变化的消息驱动机制。采用该方法,仿真系统能够支持学员的随意性操作,在电路任意状态下给出合乎原理的演示结果;除了常规的故障设置和排除功能外,还实现了插接件拔开和接触不良的状态模拟,弥补了目前仿真系统的不足。该方法适用于所有开关电路仿真系统的设计。

In the automobile circuit simulation training system promoted recently, the working status of coupling can not be simulated, and the student＇s operation is limited by the fixed movement sequence. In view of these questions, memory structure of circuit vector graph is determined. Based on this structure, a message-driven method that the elements of edge-array are changed by the user operation is proposed. Using this method, the simulation system supports student＇s capricious operation, and produces reasonable result in any situation. Except establishing and removing breakdown, couplings pulled out and in loose contact is simulated. So the shortcoming of present simulation system is made up. This method fit for simulation of all switch circuit.
