Airport Floodlighting Control Strategy and Fault Diagnosis
High-mast lights on the apron are a crucial infrastructure for airport floodlighting and play a vital role in promoting smart airport construction. Traditional high-mast light management methods mostly rely on long-term timed control or manual on-site control, resulting in high energy consumption, low control efficiency, difficulty in effectively addressing lighting shortages due to sudden weather events, and a lack of timely diagnosis of system anomalies and faults, causing numerous difficulties for apron operations. Therefore, this paper focuses on the intelligent control strategy and fault diagnosis mode of the apron floodlighting system.
The main causes of high-mast lighting power cable failures include: (1) natural damage, such as overload caused by aging of the lines during use; (2) external damage, such as line damage caused by improper wiring and burial during construction on the apron; (3) interface failure, as the interface in the circuit system is a fragile component and a common location for failure; (4) environmental factors, such as premature aging of cables due to long-term abnormal climate; (5) improper operation, such as improper wiring or missing wiring caused by negligence of construction personnel; and (6) other factors, such as theft or animal grazing.
Currently, there are some deficiencies in the control of floodlighting on many aprons. On the one hand, energy consumption is high and management is inefficient; on the other hand, lighting fault diagnosis is not timely. Fault diagnosis of high-mast lighting on aprons is also a major component of the floodlighting system. To reduce energy consumption, improve staff efficiency, and enhance the operational efficiency of high-mast lighting, an automatic on/off control strategy for high-mast lighting based on flight schedules is designed. This strategy manages the high-mast lighting in real-time according to flight operation data, aiming to save energy while extending the lifespan of the high-mast lights.
The timed control strategy for apron lighting addresses the changing lighting needs of the apron with local time. It controls the activation of high-mast lighting when natural light illuminance is insufficient due to time variations. Traditional control methods require personnel to verify local time and operate the high-mast lights within specified timeframes.
Based on the current status of the apron floodlighting system, the actual conditions of apron lighting, and lean design principles, the following principles must be followed when designing the high-mast lighting control strategy:
1) Reliability Principle: The importance of apron illuminance for airport apron operations necessitates that the high-mast lighting control strategy, while pursuing precision, meets lighting requirements. In the process of building a type-four airport and achieving energy conservation and emission reduction, ensuring the reliability of apron lighting is paramount, guaranteeing sufficient illumination rate and required apron lighting illuminance. 2) Redundancy principle: To ensure the reliability of the control strategy, multiple types of high mast light control strategies are designed for the same apron high mast light within the same time period according to different illuminance requirements. This ensures that if one strategy fails, there are other control methods to control the apron high mast light to ensure the lighting effect.
