基于TCP服务器的DI/DO模块的软件仿真

Software Simulation of Digital Input and Output Module Based on TCP Server

计算机监控系统广泛应用于众多领域。本文设计了一个基于TCP服务器的开关量输入与输出仿真软件模块,给出了仿真软件模块的可视化软件模型和对等的硬件模型,制订了通信协议用于操作仿真软件模块,并对.NET框架的TCP类进行了改进,提高了编程效率。最后,对仿真软件模块进行了严格的测试,并给出了应用实例。

Computer monitor systems are widely applied in manyifelds. In this paper, a simulated module based on TCP server which supporting digital inputs and outputs is designed and developed, including the hardware model, visual software model, communica-tion protocols which operate the simulated module, the key technology of TCP server based on .NET framework is proposed too. Finally, the simulated module is tested strictly by Program on Universal TCP Client; applied cases based on the simulated module are given too.
