Research And Design Optimization Of Intelligent Lighting Based On Metro Station

With the rapid development of the social economy and the continuous advancement of urbanization,China's rail transit industry has developed rapidly in recent years.In order to alleviate the pressure on the road network,with its speed and space saving,the subway provides many conveniences for people.Due to the large volume of transportation and long running time,the metro station can be seen a large energy-consuming program in a city.Under the premise of ensuring operational safety,reducing the energy consumption of the metro station is conducive to achieve energy-saving and emission reduction targets proposed.According to the energy-saving assessment report of rail transit engineering,the lighting system accounts for 20%~30% of the total power consumption of a metro station.Due to the lighting system's single lighting control mode in the metro station,the actual station illumination cannot be timely feedback and adjusted,resulting in lighting energy consumes more power.In this thesis,through the in-depth study of the intelligent lighting system of metro station,the system control mode has improved,and finally the lighting design optimization scheme that can effectively save the power consumption of the lighting system is summarized.The main work of this thesis as follows:(1)Firstly,this thesis analyzed the current situation of the metro station's illumination status.It is found that the BAS control system is relatively simple,low operability,and the utilization rate of the lamps is low,which cannot meet the goal of energy saving and emission reduction of a metro station.During the switching mode of the BAS system,the light environment changes obviously,resulting in low comfort,easy to cause safety hazards,and seriously affecting the safety of a passenger's travel.In response to these problems,the design optimization of the intelligent lighting system of the metro station is necessary.(2)Based on the research of the status quo in a metro stations,the optimal design of the control mode is proposed to solve the problem of high energy consumption and low safety of a station lighting system.Through the overall design and architecture the main control mode and communication mode of the intelligent lighting system,lighting acquisition mode and human interaction mode are analyzed,and optimized the software hardware system of the intelligent lighting system of the metro station.Under the premise of safe operation,reduce the energy consumption of the lighting system and achieve the goal of energy saving and emission reduction.(3)Finally,the author has verified and analyzed the optimized design results of the intelligent lighting system in a metro station.After optimization and design by intelligent lighting control system simulation software,illuminance collection and analysis of the station site where the system has been implemented.Modeling in the laboratory to analyze the feasibility of the system and verify.It is concluded that the intelligent lighting system can achieve the effect of energy saving and emission reduction improving the safety of passengers.Therefore,the intelligent lighting system of this design can effectively solve the problem of high energy consumption of the lighting system in the metro station while improving the safety and reliability of the lighting,and better achieve the goal of energy saving and emission reduction.
