基于线程消息映射的虚拟仪表设计方法

Design Method of Virtual Instrument Based on Thread-Message Mapping

针对Win32控制台下单线程虚拟仪表设计与仿真系统融合存在的问题,提出了一种基于线程消息映射的虚拟仪表设计方法。该方法在主线程里运行主控程序,在每个辅线程里运行各虚拟仪表(含虚拟面板),通过线程消息映射机制实现仿真系统中主线程与各虚拟面板辅线程的控制与协同。实践表明,该方法可以大幅提升仿真系统的模块化设计效率、仿真的互操作性和模型的可复用性。

Aiming at the problem during the fusion process of virtual instrument with simulation system in single thread under Win32 console,put forward a virtual instrument design method based on thread-message mapping mechanism.In this method,the main control program is running under primary thread,and each virtual instrument（including virtual panel） is running under every associate thread.By the thread-message mapping mechanism,the method implements the fusion and cooperation of primary thread with each associate thread running virtual instrument.The practice shows that the method can greatly promote the modularizing efficiency,the interoperability of simulation and the reusability of model in simulation system.
