随着我国城镇化的快速建设和发展,城市道路工程建设中道路照明系统的设计和维护也变得越来越重要,夜间道路照明的质量直接关系到道路车辆行驶的安全,同时随着国家经济的发展,能源问题日益突出,如何能最佳合理的布置路灯,如何才能将路灯的照明优化,越来越成为急需解决的问题。其中相对偏僻的路段,行人稀少,但是路灯却经常彻夜通明,对电能造成了极大地浪费。良好的道路照明就是考虑道路环境、路面类型、有无人行道、交通量等相关因素,进行光源光色、灯具选择,灯具排列布置,合理的照明控制设计,达到满足驾驶员、行人交通安全的视觉信息采集,提高路段的安全性和舒适感,并最终达到降低维护使用成本的目的。本设计根据分析偏僻路段照明控制要求,选用西门子PLC S7-200系列,通过手动控制和分段时序控制对路段照明系统进行控制,同时针对手动控制和分段时序控制方案设计了基于PLC的硬件与软件系统。
With the rapid construction and development of urbanization in our country, the design and maintenance of road lighting system in the construction of urban road projects have become more and more important. The quality of road lighting at night is directly related to the safety of road vehicles. At the same time, with the national economy The issue of energy has become increasingly prominent. How to best and best dispose the street lights and how to optimize the street lighting can be a problem that needs to be solved urgently. Of these relatively remote sections, pedestrians are sparsely populated, but street lights often illuminate the night, causing great waste of electricity. Good road lighting is to consider the road environment, the type of road, with or without the sidewalk, traffic and other related factors, the light source color, lamp selection, lighting arrangement, reasonable lighting control design to meet the driver, pedestrian traffic safety vision Information collection, improve road safety and comfort, and ultimately reduce the maintenance and use of the purpose. The design based on the analysis of remote road lighting control requirements, the selection of Siemens PLC S7-200 series, through manual control and segment timing control on the road lighting system control, and for manual control and segment timing control program based PLC hardware and software design Software system.
