The necessity of intelligent lighting in airports
On January 7, 2022, the Civil Aviation Administration held a press conference. At the meeting, Bao Yi, deputy director of the Development Planning Department of the Civil Aviation Administration, introduced the "14th Civil Aviation Administration of China" Relevant contents of green civil aviation development in the "Five" development plan. Based on the overall national green construction requirements and combined with the characteristics of my country's civil aviation development stage, the "Plan" proposes two indicators: transportation aviation ton-kilometer carbon dioxide emissions and airport unit passenger energy consumption. It is expected that by 2025, the five-year cumulative average will be reduced to 0.886 respectively. kilogram and 0.853 kilogram of standard coal.
According to statistics, lighting accounts for about 27% to 30% of the entire airport's electrical energy consumption. With the implementation of the "double carbon" policy across the country, lighting energy conservation has also become a top priority for airport emissions reduction. In addition, lighting covers a wide area in the entire building energy consumption comprehensive management system, involves many points, and requires high timeliness of fault handling.
The terminal building of the airport has diverse and complex application functions and belongs to a type of comprehensive building. The design of the lighting system has higher standards and more complex requirements than ordinary building lighting systems. Airport terminals usually have a large floor area, and the public lighting system involves a wide range of application scenarios, including not only general lighting in work areas, but also rich decorative advertising and related sign lighting. It also needs to create space aesthetics at night. Therefore, there are many types of lamps used in the system and they are widely distributed. If the lighting is only manually adjusted manually, it cannot be done in a timely manner. It will not be able to provide a good lighting environment for passengers and flight crews, let alone reasonable lighting, save energy, reduce emissions, and eliminate waste. Therefore, it is particularly important to do a good job in intelligent energy-saving management and planning and design.
The current situation of airport lighting
Most modern terminal buildings use huge glass curtain walls in order to better utilize natural lighting resources. According to research data from relevant institutions, human vision can accurately understand the depth of space when the illumination level is 200lx. The "Architectural Lighting Design Standards" also set the departure hall and baggage claim hall at 200lx. In fact, airports pay more attention to the lighting of the departure hall. It is common that the space illumination of the baggage hall is relatively weak. This may be due to the lack of skylight in the closed space. . There is another situation that is also very common. When the top light is insufficient, the incident light of the huge glass curtain wall is reduced, causing an obvious white hole effect in the room, and people and objects become silhouettes. Many airports have not installed intelligent control systems that can automatically adjust according to weather and natural light intensity. Therefore, on rainy days when there is insufficient daylight, the contrast becomes even more obvious.
The lighting in airport terminals often needs to be adjusted in conjunction with outdoor lighting, and the application scenarios are rich, and lighting adjustments and conversions need to be made in a timely manner according to the scenarios. In airports without intelligent control systems, light adjustment requires a lot of human resources for manual control, which will inevitably lead to low efficiency.
Design Ideas for Airport Intelligent Lighting
Airport terminal lighting system consumes a huge amount of power energy. Simply relying on the control of corresponding density values of lighting power in each area, introducing low-energy lighting fixtures and energy-saving light sources is often not enough and cannot be achieved. Good energy saving goals. Therefore, the lighting control system can be designed and planned based on intelligent ideas:
(1) According to the outdoor environmental conditions, light changes and system parameters, the automatic control design of the lighting system opening period, the number of light sources, and the brightness of the light should be done, so that the lighting system meets Preset lighting effects to meet scene application needs. Specifically, it covers the lighting control of the airport terminal building equipment management and control system, the intelligent special lighting management and control system, and various energy-saving lighting systems that embody intelligent identification, analysis and memory functions formed by program control, photometric control, specific time control, etc.
(2) The intelligent lighting energy-saving management and control system of the airport terminal should use daily design procedures to control the start and stop of the lighting circuits in each place. The intelligent independent lighting management and control system can be used to control and operate the energy-saving, making it a building control system. Management system subsystems. At the same time, the sub-control sites of the intelligent lighting system should be set up and related servers should be equipped to monitor the overall lighting circuit in the control area. The lighting system management center should be set up in the monitoring center to be responsible for the lighting system management of the entire terminal building. The main station uses optical cables to connect the network systems with each sub-station.
(3) The person in charge can use the visual tool software in the control center to understand the operation control status of the lighting system loop. When the system fails, the system will automatically send alarm information to the manager through SMS to ensure the healthy operation of the overall lighting system. Zoning managers can also strictly control the lighting systems in corresponding areas through sub-control stations.
AcrelEMS microgrid energy efficiency management platform and intelligent lighting solutions realize energy saving in airport lighting
AcrelEMS platform airport terminal lighting system should realize intelligent control and management of airport lighting. The intelligent components of each module of the system can work independently, improving the overall reliability and reliability of the overall system. Comprehensive security. The switch driver has a self-locking device, so the module will not be released improperly after power is cut off, and will always maintain its original stable state. The system realizes intelligent detection of loop current and makes a complete comparison with the normal loop. Once the light source causes a fault phenomenon, the fault information is released in a timely manner and the loop current is displayed on the large screen of the main station. In order to save energy, necessary light detection devices are installed to enable corresponding start and stop management of lamps in the airport terminal building based on the brightness of natural light sources and indoor illumination.

AcrelEMS lighting management and comprehensive energy consumption analysis system
performs overall monitoring of lighting in waiting halls, walkways, and offices, and can realize manual control, automatic control, scene control, etc.
Comprehensive analysis of lighting energy consumption, based on the analysis of lighting energy consumption data in the past period, to help airport staff formulate reasonable lighting strategies. For example, during late night hours, lights need to be turned off in some areas of the terminal. At this time, the lighting intelligent management and control system should control and manage according to time procedures and relevant flight information. First, determine whether there is flight information in each area. If the illumination meets the set standards and the flight gap is long, 30% or 60% of the lights in the area can be turned off. If there is no information, the entire light can be turned off.
Summary
In short, based on the energy saving goal, we can only carry out scientific research on energy saving management and control of airport intelligent lighting and formulate optimized energy saving management and control design strategies in order to improve the efficiency of electric energy use, reasonably save energy losses, and then promote the intelligent and sustainable airport lighting system. sexual development.
