Why the Algerian Capital Airport uses a high pole lighting control system
For most airport jets at home and abroad High pole lights The problems of timing control and light-sensitive control are adopted. Based on the control method of multiple illuminance sensor group decision-making and the automatic control method of all-fiber ring network, an intelligent high-light control system is proposed and adopted in Algeria. The practical application of the airport airport aerodrome lighting control system project verified that the proposed control method greatly improved the intelligent level of the aerodrome lighting control system.
The apron high pole lighting control system, as an important part of the airport lighting system, plays an important role in the actual operation of the airport, and its automatic control capability reflects the apron. The level of intelligence of the lighting control system. At present, the level of intelligence of the apron lighting control system is not very high.
This paper designs a smart aerodrome lighting control system based on multi-illuminance sensor group decision control and automatic control of all-fiber ring network. It can collect ambient illuminance changes according to multiple illuminance sensors, combined with automatic The control and monitoring center intelligently and automatically controls the apron high pole lights. 1 System Overview The Algeria Capital Airport apron lighting control system consists of 1 apron monitoring center and 2 sub-control centers. It can remotely monitor 32 high pole lights in two areas, at the top of each high pole light pole. An illuminance sensor is installed to collect the illuminance, and the collected illuminance information is sent to the apron lighting monitoring center through the terminal controller installed in each high pole light kiosk. The 32 high pole lights are divided into two zones, each consisting of 16 high pole lights, and the data of all the high pole lights of the terminal are sent to the monitoring center through two fiber optic rings. The structure of the apron high pole light control system is shown in Figure 1.
2 System composition
2. 1 High pole light terminal controller
The principle of the high pole light terminal controller is shown in Figure 2. The controller has three inputs, which respectively collect the high pole light two circuit and one obstacle light contactor. The feedback signal monitors the running status of the high pole light in real time. The illuminance information collected by the illuminance sensor feeds the switch voting information to the controller through the fifth input of the controller. The controller collects the electric energy, current and voltage values of the three-phase smart meter through the communication port, calculates and analyzes the fault condition of the high pole lamp through the switch lamp command and the collected current and voltage values, and the control command controls the high pole light through the output relay. The switch communicates with the apron lighting monitoring center via a fiber optic ring switch.
2. 2 Multi-illuminance sensor group decision method
The group decision process for controlling the high pole light switch is shown in Figure 3. All the illuminance sensors at the top of the pole are periodically processed to detect the ambient illuminance, and the voting information of the switch lights is obtained, and the voting information is fed back to the controller in the high pole light kiosk. 32 controllers calculate the voting information of all the high pole light node switch lights, and send the voting information to the apron lighting monitoring center. If the number of high pole lights nodes is greater than the preset value, the monitoring center sends them to all controllers. Light control command, otherwise send light control command.
The intelligent control method combined with multi-illuminance sensor group decision and all-fiber ring network automatic control applied in Algeria Capital Airport greatly improves the apron lighting control system The intelligent level solves the problem that the photosensitive control and timing control are susceptible to interference from lighting, dust, weather and other factors, and the control is not flexible. It ensures airport aerodrome lighting, improves the operational management efficiency of the apron lighting, reduces personnel input, and greatly reduces the machine. The energy consumption of the Ping Gao pole lamp. In addition, the system also reserves the interface for flight information access. In the future, high-light lighting can be controlled according to flight information, which can further improve the intelligent level of the aerodrome lighting control system.
