摘要
介绍了网络化信息采集与处理系统在智能交通系统中的应用,该系统为主从机结构。其中,主机为PC机,从机为8031单片机最小系统、A/D转换器及传感器构成的信号采集系统。主从机之间通过RS-485进行通信。对于交通灯的控制,系统采用了神经网络决策法,神经网络的应用使得系统控制具有较高的准确率。经检验,系统具有良好的人机界面、可靠的远程通讯和不错的控制效果。
In this paper,a network information acguisition system in the ITS (intelligent transportation system)is described,and the system is combined by the PASM(principal and subordinate machines). The principal computer is a PC,and the subordinate is information acguisition system which is constructed by the minimum system of 8031 one- chip computers,A/D converters and sensors. And the communication between the PASM is carried by RS-485.We control the transportation base on the neural network. And thus we get higher accurate rate. The application shows that this system runs stably,and it is of good man-machine interface and accurately.
