[0022] The present disclosure will be further described below in conjunction with the embodiments shown in the drawings.

[0023] Figure 1 is a flowchart of the approach light monitoring method according to an embodiment of the present disclosure. The execution subject of the approach light monitoring method is the approach light monitoring system. The approach light monitoring method includes the following steps.

[0024] Step 101, obtain the current state information of each approach light in the airport.

[0025] The state information of the approach light includes: on / off state, brightness, and color.

[0026] Step 102: Obtain the track message of the aircraft within the airport, and add the aircraft to the airport model.

[0027] The track message of the aircraft is provided by the air traffic control information system, for example.

[0028] Step 103: Change the display state of the navigation lights in the airport model according to the current status information of each navigation light, and set the position of the aircraft in the airport model according to the track message of the aircraft within the airport.

[0029] Step 104: Display the airport model.

[0030] Specifically, display the current state of the airport model (including the state of the flight chess and the state of the navigation lights).

[0031] By adopting this method, the tower staff and the navigation light maintenance staff can visually observe the current states of each navigation light and each aircraft within the airport. Once a navigation light fails, the navigation light maintenance staff can locate the navigation light according to their permissions and arrive at the scene in time to maintain the navigation light. In this way, the efficiency of airport navigation light management can be improved.

[0032] In some embodiments, the method further includes: responding to the operation of the user on the display interface, and setting the state of a single navigation light or a group of navigation lights.

[0033] For example, the user can turn off or turn on a specific navigation light on the display interface of the navigation light monitoring system. The user can also turn off or turn on a group of navigation lights on the display interface of the navigation light monitoring system.

[0034] In some embodiments, the method further includes: parsing the identifier, current altitude, and current speed of the aircraft from the flight message, and displaying the identifier, current altitude, and current speed of the aircraft near the display area where the aircraft is located on the display interface.

[0035] The display interface of the navigation light monitoring system not only displays the aircraft moving within the current airport, but also synchronously displays the current altitude and current speed of the aircraft. This enables the user to have a more intuitive understanding of the current operation situation of the airport.

[0036] In some embodiments, the method further includes: calculating the current attitude of the aircraft according to the position information of the aircraft, and displaying the attitude of the aircraft near the display area where the aircraft is located on the display interface.

[0037] The attitude information includes, for example, the orientation information. The user can visually see the current real attitude of the aircraft on the display interface. This helps the airport management personnel accurately grasp the state of the aircraft within the airport.

[0038] In these embodiments, the attitude information of the aircraft is inferred by the navigation aid light monitoring system.

[0039] In some embodiments, the method further includes: parsing the identifier and current attitude of the aircraft from the flight message, and displaying the identifier and attitude of the aircraft near the display area where the aircraft is located on the display interface.

[0040] In these embodiments, the attitude information of the aircraft is obtained by the navigation aid light monitoring system.

[0041] In some embodiments, the method further includes: in response to an instruction from the advanced surface movement guidance and control system, setting the states of the taxiway centerline lights and stop bar lights to guide the taxiing of the aircraft.

[0042] The advanced surface movement guidance system can send control instructions for the taxiway centerline lights and stop bar lights to the navigation aid light monitoring system, and then the navigation aid light monitoring system controls the lighting and extinguishing and colors of the taxiway centerline lights and stop bar lights to guide the taxiing of the aircraft.

[0043] Figure 2 It is the logical structure diagram of the navigation aid light monitoring system according to the embodiments of the present disclosure. Figure 3 It is the equipment layout diagram of the navigation aid light monitoring system according to the embodiments of the present disclosure. Based on the same inventive concept as the foregoing embodiments, in combination with Figure 2 and Figure 3 , the embodiments of the present disclosure further provide a navigation aid light monitoring system, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein, the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the foregoing method.

[0044] The navigation aid light monitoring system is used to monitor and control the navigation aid light system and related equipment at the airport. The navigation aid light monitoring system is a completely independent monitoring system, which can monitor and control single lights on the runway, taxiway and related areas. Based on this monitoring function, combined with specific sensors and other related systems, this system can implement certain logical judgment and control functions through software to realize the status monitoring and control of the navigation aid lights. The system can assist in guiding the aircraft on the ground by managing the lighting-related equipment, and improve the utilization rate of the airport runway and taxiway.

[0045] The navigation aid light monitoring system conducts information interaction with the single-light monitoring system and the Advanced Surface Movement Guidance and Control System (A-SMGCS). The single-light monitoring system (hereinafter referred to as SLCMS) is used to physically implement underlying functions such as single-light monitoring, information interaction of sensors, and stopping row macros. It can provide information interfaces to other systems as needed and operate independently without being controlled by any system when the control authority is not transferred.

[0046] The navigation aid light monitoring system can be used to formulate and execute various lighting monitoring logic programs, and provide a convenient and friendly human-machine operation interface for tower personnel and maintenance personnel, enabling them to conduct comprehensive real-time monitoring of the airport runway. This system can automatically generate system data reports, and can also monitor internal and external devices of the system in real time, issue early warnings and alarms in case of faults, and record the corresponding processes for analysis and troubleshooting. At the same time, the navigation aid light monitoring system also integrates devices such as CCR (constant current dimmer), UPS (uninterruptible power supply), high / low voltage power systems, and diesel generators, and monitors them.

[0047] Using the maintenance client of the navigation aid light monitoring system, maintenance personnel can quickly and conveniently obtain the working status of each light and each device of the navigation aid lighting system, thus greatly accelerating the maintenance speed and efficiency.

[0048] This system reserves space for future system expansion and can also be used as a subsystem of the A-SMGCS system. After being connected to the A-SMGCS system, this system will be integrated into the A-SMGCS system, and tower personnel can control the navigation aid light monitoring system through the A-SMGCS system.

[0049] Reference Figure 3 , the entire lighting monitoring system is distributed in the air traffic control tower, apron tower, lighting station, maintenance center, runway, and taxiway of the airport.

[0050] As the maintenance and management center of the navigation aid light monitoring system, the maintenance center controls and monitors the lighting series circuit and low-voltage parallel power supply objects, and feedbacks the operation status of the runway and taxiway lights throughout the field.

[0051] Redundant ring network communication is adopted between different sites (such as maintenance center, lighting station, etc.) of this system.

[0052] The monitoring terminals in the maintenance center, tower, and each lighting station all have a human-machine interface that displays the entire airport configuration, and monitors and controls the entire system under appropriate permissions.

[0053] The client is at the upper layer of the system, communicates with the server through network devices, and sends or receives various types of information. The server sends the collected information to the required clients and receives commands to transfer to fieldbus devices. The fieldbus devices directly or indirectly contact the target execution devices through specific interface devices to perform specific tasks.

[0054] The dimmers, switch cabinets and discrete field devices adopt field Ethernet bus, which is responsible for the physical and logical connections between the server and the controlled objects.

[0055] The core server is located in the maintenance center and is the center of the entire monitoring system. In addition to being responsible for processing all the instructions issued by customer terminals and parsing all the data uploaded by lighting stations, it also serves as the interface center with the A-SMGCS system of air traffic control, and can directly execute the instructions of the A-SMGCS lighting guidance control system to control the whole-field lighting system.

[0056] The following introduces a complete control process.

[0057] 1) The control personnel issue control commands on the display interface of the navigation aid light monitoring system, including: switching the power supply circuit, switching the lamps, querying the status of monitored objects, querying fault alarms, and querying historical records.

[0058] 2) The human-machine interface program interprets the received commands and converts them into corresponding data packets through analysis.

[0059] 3) The data packets first enter the backbone network through the fiber optic Ethernet switch.

[0060] 4) The backbone network switch routes the data packets and sends them to the core server.

[0061] 5) After the core server processes the data packets for the second time, it distributes them to the next-level objects (field server, historical server).

[0062] 6) The historical server will feedback the results to the core server after the commands are executed and then send them to the client. The historical server not only records the operation results, but also records the operations themselves, fault alarms, received commands or other necessary records.

[0063] 7) The field server processes the data packets and transfers them to the control devices.

[0064] 8) The control devices analyze and process the data packets and execute the commands.

[0065] 9) The control devices feedback the execution status of the commands and transmit them back to the client through the above-mentioned network path.

[0066] 10) The human-machine interface program interprets the received status information and displays it on the human-machine interaction interface.

[0067] 11) The controller obtains the execution status of the command and the process ends.

[0068] The stop bar macro is a set of control logic for the stop bar lights. Figure 4 When the user selects the "Release" checkbox, the automatic guidance function for the stop bar at the intersection numbered SBM-WS8-CROSS (SBM refers to the type of light, such as centerline lights or stop bars. WS8 refers to the circuit name, and CROSS refers to the cross circuit. This format is not fixed and can be customized). This means that the navigation light monitoring system detects the taxiing position of the aircraft and sequentially illuminates or extinguishes the required taxiway centerline lights and stop bar lights.

[0069] The normal release logic is as follows:

[0070] a) Extinguish the stop bar lights, illuminate the taxiway centerline lights required for guidance ahead of the stop bar, and taxi forward.

[0071] b) The aircraft taxis forward to the second inspection point, turns off the centerline lights of the first taxiway section, and lights the stop bar lights at the same time to prohibit the next aircraft from entering.

[0072] c) The aircraft taxis forward to the next checkpoint and turns off the taxiway centerline lights as it passes.

[0073] d) Repeat the previous step until the next process.

[0074] e) The aircraft continues to taxi forward and reaches the guidance end position. The centerline lights of the last taxiway section are extinguished and the stop row system is restored to the initial prohibited state to prepare for the next release.

[0075] During the release process, the arrival of an aircraft at a certain location is detected by a microwave detector. If the aircraft's crossing cannot be detected due to a detector failure or the aircraft itself, the system will automatically delay for 45 seconds to execute the corresponding logic above until the guidance process is completed.

[0076] The "No Go" checkbox is typically not used. During normal operation, the system automatically resets the stop row logic to the No Go state after each automated vectoring process. The controller simply waits for the previous automated vectoring process to complete and selects the "Release" checkbox at the start of the next vectoring process. Therefore, the "No Go" checkbox is only necessary if the controller needs to manually reset the stop row to the No Go state during the vectoring process.

[0077] When the stoplight at a certain intersection is out of use, first press the graphic button corresponding to the intersection, then select the "Disable" radio button, and then click the OK button.

[0078] Disabling the stop bar system means that the automatic guidance function of the stop bar system fails, that is, the navigation aid light monitoring system stops detecting the taxiing position of the aircraft, and always keeps the stop bar lights off and the taxiway centerline lights on.

[0079] The following introduces the 3D display related functions of the navigation aid light monitoring system.

[0080] The data sources are as follows:

[0081] A. The customer will provide information related to the airport, including the buildings, runways, taxiways, numbers, shapes, sizes and positions of various navigation aid lights. The module responsible for modeling inside the system will identify them according to various information and export them into a configuration file to complete the modeling of the fixed items at the airport.

[0082] B. The most direct source of dynamic target position data is the radar. There are a large number of radars distributed in each airspace, and there are even various radars including multi-point lidar installed on the airport ground. The track information is sensitive information, and it will be very troublesome to obtain it directly from the radar system. The radar system has been integrated into the air traffic control information management system. Considering the cost and feasibility, the data source of this system is the air traffic control information management system or any system that can provide track messages.

[0083] 2. Data Content

[0084] A. Name of the object

[0085] B. Number of the object

[0086] C. Shape of the object

[0087] D. Size of the object

[0088] E. Position of the object

[0089] F. Data source ID

[0090] G. Service user ID

[0091] H. Track number

[0092] I. UTC time

[0093] J. Target identification code

[0094] K. Single / multi-sensor mode (one in the track information, referring to whether the basis for judging the aircraft state is single or multiple, see CAT062)

[0095] L. Geometric height and barometric height

[0096] M. Data source required for track height calculation

[0097] N. Track is predefined or temporary

[0098] O. Real or simulated track

[0099] P. Whether it is ADS - B data (transponder)

[0100] 3. Data processing

[0101] A. First, complete the modeling of the object according to the object's data.

[0102] B. Then, model the terrain according to the terrain data

[0103] C. Combine various types of modeling on one interface to complete static modeling.

[0104] D. Associate various data control and query instructions with the completed modeling (display, control, query object status) for operation on the interface.

[0105] E. Display the overall process of the target: Process the track message, obtain information such as the aircraft identification code, position, speed, and attitude within the current airspace of the airport, call the model in the library, and display the aircraft on the interface.

[0106] The specific process is as follows: Parse the message to obtain the target identification code and the number of targets. The target's horizontal position is represented in two's complement form in the Cartesian coordinate system with an accuracy of 0.5m, or in the form of longitude and latitude in the WGS - 84 geocentric coordinate system with an accuracy of 180 / 225. It is necessary to calibrate the absolute zero point on the built model, and then after processing the horizontal position information, convert it to the position on the interface. The geometric height information of the track is defined as the vertical distance projected on the Earth ellipsoid, coming from WGS - 84, and is also represented in two's complement form. At the same time, there is also the barometric height information of the track, which needs to be processed according to the track information, select the more reliable one, and add it to the target's information. For the target's attitude information, if the processed track message includes information such as the target's acceleration and orientation, the target's attitude information (pitch, horizontal angle) can be obtained after calculation. If there is no such information, the system will calculate it based on two consecutive positions within a certain period of time.

[0107] F. After all necessary information processing is completed, the system displays the 3D model of the target on the interface and marks the target's status information near the 3D model.

[0108] Monitoring system

[0109] When the A - SMGCS system is running, the positions where all light segments are lit should be related to the trajectory that the aircraft will pass. If it exceeds this range, corresponding alarms will be given according to the situation.
