基于TCP/IP协议栈的嵌入式网络控制系统设计

摘要

网络控制系统(NCS)是指传感器、执行器以及控制器通过网络进行数据通信的控制系统,它不仅是1个控制系统,还是1个网络系统.网络中的各种复杂因素使得网络控制系统的设计非常复杂.为此,提出了1种基于TCP/IP协议栈的嵌入式网络控制系统体系结构,并对其中的核心模块--网络层进行了实现.在此基础上,开发了远程电机控制系统.开发实例表明,所提出的网络控制系统体系结构简单、方便,即使开发人员不懂通信,也可以很容易地通过模块化构造实际网络控制系统.%A networked control system ( NCS) is referred to a control system ,in which the sensor, the actuator and the controller communicates through network. NCS is not only a control system , but also a network system. Due to the diverse factor in network ,it is sophisticated to design a NCS. An architecture for embedded NCS based on TCP/IP protocol is firstly proposed, then the key module in which-the network layer is realized. Finally, A NCS for motor based on the architecture is developed. It demonstrates that, the proposed architecture of NCS is simple and convenient. A person can constructs a NCS easily ,even he does not understand well communication.
