Problems solved by technology

Therefore, there are a huge number of centerline lights and stop bars at the airport, and it is a very difficult job to manually control the navigation lights to guide the aircraft to taxi
[0005] In addition, during the operation of busy airports, the increase of ground taxiing conflicts is geometrically related to the increase in the number of aircraft. Only by controlling the navigation aid lights to avoid surface conflicts, the surface operation is likely to violate relevant control regulations, and it is difficult to meet the requirements of airport surface safety. requirements, making it difficult to increase airport capacity

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0031] Such as figure 1 As shown, the present invention proposes a distributed scene navigation light control system based on the discrete event monitoring theory, which needs to sequentially implement the intersection operation module, the straight line segment control module, and the stop bar and center line light coordination control module oriented to conflict control.

[0032] 1. Intersection Operation Module

[0033] The stop bar light control at taxiway intersection adopts the hybrid control structure to design the control decision structure of the stop bar light, and its decision structure is as follows: figure 2 shown. The Petri net controller is used as the discrete controller of the stop bar lights, and the information interaction with the continuous taxiing state of the aircraft is realized through the interface part. During the operation of the i...

Abstract

The invention discloses a system and method for controlling distributed airport navigation light. The system comprises a scene movement state sensor, a control tower monitor, an intersection controller, a coordination controller, a straight line section controller and a light signal PLC (Programmable Logic Controller) output interface which are connected for networking through a redundant Ethernet. The method comprises the following steps of: converting a position signal of a scene moving target into a state signal of the scene movement by the control tower monitor; sending the state signal to a light controller; encoding control instructions generated by the controller; and transmitting the control instructions to a specified light station through the redundant Ethernet so as to control a dimmer of each controlled target. In the invention, the effective guidance of airport scene movements under all-weather conditions is realized; the opening state of the scene light is automatically controlled through the light controller, the global optimum movement countermeasure advice is provided in real time, and the efficient and accurate guidance on moving target gliding and ground traffic is realized.

Description

technical field [0001] The invention relates to a distributed airport navigation light control system and method, which belongs to the airport surface movement control system and method. Background technique [0002] With the rapid development of the global air transport industry, bad weather and low visibility have brought increasing pressure on the safe and efficient operation of airports. In order to solve the above two problems, the international community is gradually researching and testing a new concept of ground control—Advanced Surface Movement Guidance and Control System (A-SMGCS). The A-SMGCS system directly reflects the activity situation of the moving target on the surface to the display in front of the tower controller through effective monitoring technology, and carries out control alarm, route planning and guidance on the target, making the airport safe and orderly in all-weather weather , Efficient operation. [0003] Internationally, the A-SMGCS system is...
