交通灯智能网络化控制的系统设计
摘要:近年来随着科技的飞速发展,PLC的应用正在不断的走向深入,已广泛应用于工业过程和位置的自动控制中。它是已微处理器为基础,综合了计算机技术、
自动控制技术和通讯技术发展而来的一种新型工业控制装置。
可编程控制器在工业自动化中的地位极为重要,广泛的应用于各个行业,随着科技的发展,可编程控制器的功能日益完善,加上小型化、价格低、可靠性高,在现代工业中的应用更加突出。
交通信号灯的出现,使交通得以有效管制,对于疏导交通流量、提高道路通行能力,减少交通事故有明显效果。城市交通灯控制采用的可编程控制器具有可靠性高、维护方便、用法简单、通用性强等特点。分析了现代城市交通控制和管理的状况,结合交通灯实际情况和原理,本文用可编程控制器控制十字路口信号灯来说明可编程控制器硬件,软件的设计。解决好公路交通灯控制问题将是保障交通有序、安全、快捷运行的重要环节。

The design of Intelligent traffic light control work
Abstract:In recent years, with the rapid development of science and technology, PLC application to the deepening of the ongoing, has been widely used in industrial processes and position in the automatic control. It is already the microprocessor-based, puter technology, automatic control technology munication technology developed a new type of industrial control device.
PLC in the position is extremely important industrial automation, widely used in various industries, with the development of science and technology, programmable controller function is increasingly perfect, plus miniaturization, low price, high reliability, the application in modern industry is more outstanding.
The emergence of the traffic lights, traffic to effectively control, for facilitating traffic flow, improve traffic capacity, reduce the number of traffic accidents have obvious effect. Urban traffic control adopts programmable controller has high reliability, easy maintenance, usage is simple, monality etc. Characteristics. Analyzes modern urban traffic control and management, combining with the actual situation traffic condition, this paper use principle and PLC crossroads lights to illustrate programmable controller hardware, software design. Solve highway traffic control problem will be safeguard traffic orderly and safe, quick run import
