1. The necessity of airport intelligent lighting

2022 year 1 month 7 Japan , CAAC held a press conference , At the meeting, Baoyi, deputy director of the development planning department of the Civil Aviation Administration, introduced civil aviation “ the 14th Five-Year Plan ” Relevant contents of green civil aviation development in the development plan .《 planning 》 According to the general requirements of national green construction , Combined with the characteristics of China's civil aviation development stage , Put forward two indicators of carbon dioxide emission per ton kilometer of air transport and energy consumption per unit passenger of the airport , Expect to 2025 The five-year cumulative average is reduced to 0.886 Kilogram and 0.853 Kilogram of standard coal .

According to statistics , Lighting accounts for about% of the power consumption of the whole airport 27%~30% about , It will be implemented throughout the country “ Double carbon ” Dongfeng's policy , Lighting energy conservation has also become the top priority of airport emission reduction . And lighting covers a wide area in the overall building energy consumption management system , Multiple points involved , High timeliness requirements for fault handling .

The airport terminal has various and complex functions , It belongs to a class of comprehensive buildings , The design of lighting system has higher standards and more complex requirements than ordinary building lighting system . Airport terminals usually cover a large area , The application scenarios involved in public lighting system are very rich , Not only the general lighting of the work area , At the same time, it also includes a wealth of decorative advertisements and related logo lighting , It is also necessary to create space aesthetics at night . therefore , There are many kinds of lamps used in the system , Widely distributed . If the lighting is only manually adjusted , Not in time , Unable to provide a good lighting environment for passengers and aircrew , Let alone reasonable lighting , Energy conservation and emission reduction eliminate waste . therefore , It is particularly important to do a good job in intelligent energy-saving management and planning and design .

1. Current situation of airport lighting

Most modern terminal buildings use huge glass curtain walls , In order to make better use of natural lighting resources . According to the research data of relevant institutions , Illumination level at 200lx When , Only human vision can accurately understand the depth of space .《 Lighting design standards for buildings 》 Set the departure hall and the baggage claim hall as 200lx, In fact, the airport pays more attention to the lighting of the departure hall , It is common that the illumination of the luggage hall is relatively weak , This may be due to the lack of skylight in the enclosed space . There is also a common situation , When the top light is insufficient , The incident light of the huge glass curtain wall is reduced , Make the white hole effect obvious in the room , People and objects become silhouettes . Many airports are not equipped with intelligent control systems that can automatically adjust according to the weather and natural light intensity , So on a rainy day , The sky is not bright enough , This contrast is even more obvious .

The lighting of the airport terminal often needs to be adjusted together with the outdoor lighting , And the application scenarios are rich , It is necessary to adjust and convert the lighting according to the scene . In airports without intelligent control systems , Light adjustment requires a lot of human resources for manual control , It will inevitably lead to inefficiency .

1. The design idea of airport intelligent lighting

The lighting system of the airport terminal consumes a huge amount of electricity and energy , It only depends on the control of the corresponding density value of the lighting power in each site area , It is often not enough to introduce low-energy lamps and energy-saving light sources , Unable to achieve good energy saving goals . Therefore, the lighting control system can be designed and planned based on the intelligent idea ：

（1） It shall be based on outdoor environmental conditions 、 Brightness change and setting system parameters , Do a good job in the opening period of the lighting system 、 The number of light sources 、 Design of automatic adjustment and control of illumination brightness , So as to make the lighting system conform to the preset lighting effect , Meet scenario application requirements . Specifically, it covers the lighting control of the building equipment control system of the airport terminal 、 Intelligent special lighting management and control system and all kinds of programmable lighting 、 Photometric control 、 Specific time control and other ways to form the embodiment of intelligent recognition 、 Analysis and energy-saving lighting system with memory function .

（2） The intelligent lighting energy-saving management and control system of airport terminal building shall control the start and stop of lighting circuits in various places with the help of daily design procedures , The intelligent independent lighting control system can be used for energy-saving control and operation , Make it a subsystem of the building control management system . At the same time, the sub control stations of the intelligent lighting system shall be set , And configure relevant servers , Monitor the overall lighting circuit in the control area . A master lighting system management station shall be arranged in the monitoring center , Responsible for the lighting system management of the overall terminal , The master station is connected with each substation through optical cable .

（3） The person in charge can understand the operation control status of the lighting system circuit in the control center with the help of visual tool software , When the system fails, the system will automatically send the alarm information to the manager through SMS , Ensure the healthy operation of the overall lighting system . The district management personnel can also strictly control the lighting system in the corresponding area through the sub control station .

The system realizes the intelligent detection of loop current , And make a perfect comparison with the normal circuit , Once the light source causes a malfunction , Timely release fault information , And display the circuit current in the main station screen . To save energy , Install necessary light detection devices , According to the brightness of natural light source 、 Indoor illumination shall be used to manage the start and stop of lamps in the airport terminal building .
