| 摘 要： | 利用MATLAB和Rockwell软件进行智能交通系统(ITS)的流量控制研究时，各个应用软件之间的通信至关重要。文中采用RsLinx作为服务器与Matlab进行通信：将利用PLC(ControlLogix5555)及光电传感器统计的道路流量送给matlab；并将BP神经网络预测出的下一时刻道路的流量返还给rockwell的Logix系统，经PLC的输出口来控制路口信号灯，实现道路流量控制，进而提高道路通行效率。也利用RsView与Matlab通信进行人机监控界面演示。

| Abstract: | In the ITS (Intelligent Traffic System) study with MATLAB and Rockwell Software, the communication between software is critical. RsLinx as a server communicates with MATLAB. The result of traffic flow collected by PLC and photoelectric sensor is sent to MATLAB, and the predicted value through the BP Arithmetic is returned to the Logix system. The traffic lights are controlled by the output of PLC, so that the traffic flow is well controlled and the traffic efficiency is greatly improved. Similarly, through the communication between RsView and MATLAB, the HMI is intuitionally presented. |
