Research On Intelligent Lighting Control System For Urban Roads

With the rapid development of modern science and technology,people's demands for urban road lighting equipment are also increasing.Nowadays,urban road lighting is an important part of municipal work.Urban road lighting system is of great significance in ensuring the safety of travel,improving the efficiency of road use,and beautifying the road landscape at night.The rapid progress of our country's economy promotes the development of city's traffic.The increasing of traffic flow can be seen everywhere.Each passing day,the growing number of motor vehicles will result in the increased environmental pollution and the index of energy consumption in China.Therefore,it requires us not only to meet the basic requirements of the public transport in urban traffic lighting,but also to achieve energy saving and environmental protection as far as possible,to achieve a truly intelligent energy-saving road lighting.Based it,it is necessary to study an intelligent lighting control system which is suitable for the development of urban road in China.This paper studies the development situation of domestic and foreign road lighting control system for nearly ten years.For the existing shortcomings of the road lighting system,the intelligent lighting control system is designed.The second chapter introduces the building process of lighting control system.The general framework,network architecture and function architecture of the control system are introduced in detail.In the third,fourth,fifth chapter,the control system based on the light intensity detection,the noise detection,and the human detection are introduced.This system uses PLC as the central control platform.Terminal equipment uses light sensor to collect natural illumination information.It is unified management by the city road lighting controller to control the opening and closing,and simulated illumination controlling lamp switch technology in Simulink.After midnight,enabled smart mode,through the noise sensor to collect the information in the road,using the intelligent fuzzy decision algorithm,achieving real-time adjust the open level of the lights,in order to meet the demand of traffic lighting,to save energy as much as possible.The infrared pyroelectric detection technology is used on the sidewalk,so that achieving the light control as "people come to open and people leave to shut down".Finally,the subject study is come true in the Rockwell Laboratory of the school.The ControlLogixl756 controller and KingScada configuration software are used to complete the overall design of the urban road intelligent lighting control system,and the debugging experiment is carried out.The experimental results show that the designed system meets the expected requirements.
