The Design And Research Of Intelligent Lighting Control System In Subway

With the rapid development of the national economy and the improvement of people's living standards,the significance of lighting is not only limited to the function of providing illumination,but also endowed with the decorative function of constructing a comfortable visual environment,providing directions for emergency evacuation and the mission of saving national energy.At the same time,with the rapid environment evacuation and development of urbanization in China,the scale of urban population has increased rapidly,and the problem of traffic congestion has begun to seriously affect people's travel.As an underground transportation system developed by railway transportation to meet the needs of urban operation,Metro with the characteristics of large volume,fast speed,low pollution and time-accurate is the most effective way to solve the urban traffic tension in large and medium-sized cities.With the steady development of economy and the strong support of the government,the scale of Metro Construction in China has been further expanded,and now it has become the largest metro construction market in the world.In this context,as an important part of smart city,intelligent lighting of Metro provides important support for the convenience of citizens' travel,urban energy saving and urban cultural propaganda.However,at present,there is still the waste of "long light" and "no one lighting" in the equipment area of subway station.In order to alleviate the shortage of energy in our country,further save electric energy and improve the rationality and comfort of lighting in subway station,it is of great practical significance to study and design the lighting control system in subway station.Firstly,this paper introduces the basic characteristics of DALI dimming protocol and LED light source lamps,and then uses the rapidly developing LED lamps as the object of dimming control in intelligent lighting control system.A set of control scheme suitable for lighting in the equipment area of subway station is designed.Finally,the control system is applied to a certain place.The railway station and the theory prove that the system can effectively reduce the electric energy consumption generated by the illumination in the subway station and save the electric charge expenditure and further control the operation cost of the subway station.
