摘要

为解决星上仿真系统的接口规范以及仿真交互协调的问题,建立基于CAN总线框架的交互式星上仿真系统.依照各组成部分进行建模,形成多个仿真成员,在各成员驱动程序接口之上进行二次封装,形成统一接口,再配合CAN总线仿真框架,构建星上仿真系统.设计并实现了各仿真成员之间统一的通信接口,规范了仿真流程框架,构成了各仿真成员相互交互、协调运行的基础.实验结果证明,该仿真框架传输效率高、运行德定、适应性好,达到了预期效果.%To solve the problem of interfaces and communications between different members in an on-board simulation system, an on-board interactive simulation system based on CAN bus is established. Several simulation members are built according to the composition of real system. Interfaces of drivers included in simulation members are packaged into a uniform interface, thus the on-board simulation system is established with the foundation of CAN bus simulation framework. Uniform communication interface of each simulation member is designed and realized, the framework of simulation flow is established, and foundation of intercommunion and operation between simulation members is laid. Experiment results prove that the framework can work stably with great efficiency and high flexibility, and expected effect is achieved.
