Description

Technical Field

[0001] The present invention relates to a safety control method, server, system and program product for an intersection of a taxiway and a roadway. Background Art

[0002] With the rapid development of air transportation, airport ground service vehicles are widely used in providing services for airports. There are many types of airport ground service vehicles, such as: baggage transporters, refueling vehicles, aircraft tractors, passenger boarding bridges, shuttle buses, etc. Their working quality will directly determine the service quality and safety issues of the airport and become an essential part of the airport. On the apron or taxiway of the airport, the taxiway of the aircraft and the roadway of the ground service vehicle will intersect. As the number of flights at the airport increases, the working density of the ground service vehicles also increases. At this time, special attention needs to be paid to safety when the ground service vehicle passes through the intersection. Especially in the night environment, due to limited vision, the probability of conflicts between aircraft and ground service vehicles also increases significantly, which will cause major safety accidents and flight delays.

[0003] CN113129613A provides an airport ground service vehicle passing control system and method. The system includes: a ground traffic signal array, arranged on the ground of the warning area of an entrance lane at an airport intersection, for indicating the driving state of the entrance lane; an aircraft detector, arranged on the aircraft taxiway, for detecting whether there is an aircraft taxiing on the aircraft taxiway; a signal controller, for controlling the ground traffic signal array to emit a no-passing light signal to indicate that the driving state of the entrance lane is a no-passing state when the aircraft detector detects an aircraft; and controlling the ground traffic signal array to emit a passing-allowed light signal or a warning passing light signal to indicate that the driving state of the entrance lane is a passing-allowed state or a warning passing state when the aircraft detector does not detect an aircraft.

[0004] On the premise of ensuring the safety of the operation of the intersection of the taxiway and the roadway, the operation efficiency of aircraft and vehicles needs to be further improved. Summary of the Invention

[0032] The following further describes the present invention with reference to specific embodiments, but the protection scope of the present invention is not limited thereto.

[0033] An embodiment of the present invention provides a safety control method for a taxiway and a roadway intersection. From the perspective of equipment, the execution subject can be one or more electronic devices, and more specifically, it can be a processing module therein; from the perspective of a program, the execution subject can correspondingly be a program running on these electronic devices. The method includes the following steps.

[0034] Step 101: Determine the position information and speed information of aircraft on the taxiway, and the position information and speed information of vehicles on the roadway.

[0035] For example, the position information and speed information of each aircraft on the taxiway, as well as the position information and speed information of each vehicle, can be obtained from the airport inter-field information fusion system.

[0036] The airport inter-field information fusion system is a system that can obtain the coordinate position, flight information, and speed information of aircraft. This airport inter-field information fusion system has multiple surveillance source data reception and fusion functions, and uses surveillance technologies such as automatic dependent surveillance - broadcast, multilateration, and secondary surveillance radar to locate and monitor the aircraft and vehicles on the airport. The airport inter-field information fusion system can also determine the identifiers of each aircraft and each vehicle.

[0037] Also for example, the position information and speed information of the aircraft on the taxiway, and the position information and speed information of the vehicles on the roadway can be directly determined through radar signals.

[0038] Reference Figure 1 , the aircraft coded as A1 is taxiing on the taxiway, its coordinates are (x1, y1), the vehicle numbered C1 is driving on the roadway, its coordinates are (x3, y3), and the coordinates of the center O1 of the intersection of the taxiway and the roadway are (x2, y2).

[0039] The two - color stop row lights are set on the roadway, arranged perpendicular to the extension direction of the roadway, and are located on both sides of the taxiway respectively.

[0040] In some embodiments, the two - color stop row lights can be controlled to emit red light and yellow light.

[0041] In other embodiments, the two - color stop row lights can be controlled to emit red light and green light.

[0042] Hereinafter, red is taken as the first color and yellow is taken as the second color for illustration.

[0043] Step 102: Calculate the distance from the aircraft to the intersection center according to the position information of the aircraft, and this distance is denoted as the first distance. Calculate the distance from the vehicle to the intersection center according to the position information of the vehicle, and this distance is denoted as the second distance.

[0044] Step 103: If the first distance is less than the first safety distance, trigger the stop row lights to continuously emit the first color. If the first distance is greater than the first safety distance and the first distance increases with time, trigger the stop row lights to continuously emit the second color.

[0045] The first safety distance is denoted as D base1 , the first distance is denoted as d pi , the first arrival time is denoted as t pi , the speed of the aircraft is denoted as V p .

[0046] ReferenceFigure 1 Taking the center O1 of the intersection of the taxiway and the roadway as the center, a central circular area C, an annular area B surrounding the area C, and an area A outside the annular area B are demarcated.

[0047] The first safety distance D base1 is the outer boundary radius of the annular area B.

[0048] If the first distance is less than the first safety distance, it indicates that the aircraft is currently located in the central circular area C or the annular area B. The stop light is constantly on red, prompting the vehicle driver to stop the vehicle on the side of the stop light facing away from the intersection.

[0049] If the first distance is greater than the first safety distance and the first distance increases with time, it indicates that the aircraft is currently located in the area A and is moving away from the intersection. The stop light is constantly on yellow, prompting the vehicle driver that they can safely pass through the intersection.

[0050] Step 104: In the case where the first distance is greater than the first safety distance and the first distance decreases with time, determine the time required for the aircraft to taxi to the first safety distance from the intersection based on the first distance, the first safety distance, and the speed information of the aircraft. This time is denoted as the first arrival time.

[0051] The first distance is greater than the first safety distance and the first distance decreases with time, indicating that the aircraft is located in the area A and is taxiing towards the intersection. The first arrival time describes the time required for the aircraft to taxi to the junction of the area A and the annular area B at the current speed.

[0052] Step 105: In the case where the second distance is less than the second safety distance, determine the time required for the vehicle to travel to the second safety distance away from the intersection based on the second distance, the second safety distance, and the speed information of the vehicle. This time is denoted as the second arrival time.

[0053] The second safety distance is denoted as D base2 and the second distance is denoted as d ci and the second arrival time is denoted as t ci and the speed of the vehicle is denoted as V ci .

[0054] Reference Figure 1 The second safety distance D base2 is the radius of the area C. The second safety distance D base2 is slightly greater than the distance from the midpoint of the intersection to the dual-color stop light. The difference between the two can be set to 2m to 4m. That is, the stop light is located inside the area C and away from the boundary of the area C.

[0055] The second arrival time describes the time required for the vehicle to drive out of the area C from within the area C.

[0056] Step 106. When the first distance is greater than the first safety distance and the first distance decreases with time, if the second distance is greater than the second safety distance, determine the first arrival time as the arrival time difference.

[0057] Reference Figure 1 , at this time, the aircraft is located in area A, and the vehicle is located in area A or area B. In this state, the vehicle driver has enough reaction time, and only the time required for the aircraft to pass through the intersection and slide out of the circular area B needs to be considered.

[0058] Specifically, the first safety distance is denoted as D base1 , the first distance is denoted as d pi , the first arrival time is denoted as t pi , the speed of the aircraft is denoted as V pi , the arrival time difference is denoted as Δt, and the second safety distance is denoted as D base2 , the second distance is denoted as d ci , the second arrival time is denoted as t ci , the speed of the vehicle is denoted as V ci .

[0059] If d pi > D base1 and d pi decreases with time, then t pi = d pi / V pi - D base1 / V pi , and in this state, if d cj > D base2 , then Δt = t pi .

[0060] Step 107. When the first distance is greater than the first safety distance and the first distance decreases with time, if the second distance is less than the second safety distance, determine the arrival time difference according to the difference between the first arrival time and the second arrival time.

[0061] Continue to refer to Figure 1 , in the current state, the aircraft is located in area A and sliding towards the intersection, and the vehicle is located in area C.

[0062] Specifically, if d pi > D base1 and d pi decreases with time and d cj <D base2 and the second distance d ci decreases with time, then t cj = d cj / V cj + D base2 / V cj and Δt = tpi -t cj 。

[0063] In this state, the vehicle is located in area C and is driving towards the intersection.

[0064] If d pi >D base1 and d pi decreases with time and d cj <D base2 and the second distance d ci increases with time, then t cj =D base2 / V cj -d cj / V cj and Δt = t pi -t cj 。

[0065] In this state, the vehicle is located in area C and has passed the intersection.

[0066] Trigger the stop traffic light to be constantly on in the first color, flash in the second color, and be constantly on in the second color according to the numerical range of the reached time difference.

[0067] Among them, the first safety distance is greater than the second safety distance. The first safety distance and the second safety distance are determined according to the maximum taxiing speed specified for the aircraft and the maximum driving speed specified for the vehicle, so as to ensure safety as much as possible. In one example, the maximum taxiing speed of the aircraft is 50 km / h, calculated, the maximum driving speed of the vehicle is 30 km / h, the first safety distance is 300 m, and the second safety distance is 100 m.

[0068] The greater the reached time difference, the smaller the possibility of collision between the aircraft and the vehicle at the intersection.

[0069] In some embodiments, three consecutive and adjacent numerical intervals are divided from small to large for the reached time difference. The stop traffic light is triggered to be constantly on in the first color in the interval with the smallest value, to flash in the second color in the interval with the middle value, and to be constantly on in the second color in the interval with the largest value.

[0070] In one embodiment, 4 safety levels are set. Level 0 (the stop traffic light is constantly on in yellow), the condition is Δt > 30 seconds; Level 1 (the stop traffic light flashes in yellow), the condition is 15 seconds < Δt ≤ 30 seconds; Level 2 (the stop traffic light is constantly on in red), 5 seconds < Δt ≤ 15 seconds; Level 3 (the stop traffic light is constantly on in red and a voice alarm is added), Δt ≤ 5 seconds.

[0071] When the driver sees that the yellow light of the stop signal light is constantly on, it means that it is safe to pass through the current intersection; when the driver sees that the yellow light of the stop signal light is flashing, if the vehicle has already crossed the first stop signal light of the intersection at this time, it continues to drive and pass through the intersection, and if it has not crossed any stop signal lights on either side of the intersection at this time, it stops immediately; when the red light of the stop signal light is constantly on, it means that it is necessary to stop immediately.

[0072] Four safety levels are divided according to the numerical range of the arrival time difference, and the safety reminder for the driver is more refined. On the premise of ensuring the safety of the intersection between the taxiway and the driving lane, the operation efficiency of the vehicle is further improved.

[0073] In another embodiment, three safety levels are set. Level 0 (the yellow light of the stop signal light is constantly on), the condition is Δt > 30 seconds; Level 1 (the yellow light of the stop signal light is flashing), the condition is 15 seconds < Δt ≤ 30 seconds; Level 2 (the red light of the stop signal light is constantly on), 0 seconds < Δt ≤ 15 seconds.

[0074] In yet another embodiment, three safety levels are set. Level 0 (the yellow light of the stop signal light is constantly on), the condition is Δt > 30 seconds; Level 1 (the yellow light of the stop signal light is flashing), the condition is 15 seconds < Δt ≤ 30 seconds; Level 2 (the red light of the stop signal light is constantly on and voice warning), 0 seconds < Δt ≤ 15 seconds.

[0075] In some embodiments, it further includes: when the speed of the aircraft or vehicle is zero, the arrival time difference is set to infinity. When the speed of the aircraft or vehicle is 0 (the vehicle will not stop on the taxiway), it is safe for both the aircraft and the vehicle at this time.

[0076] It should be noted that in the above determination conditions, when the two parameters are equal and the processing method is not specified, it can be processed according to the situation where the first parameter is greater than the second parameter, or it can be processed according to the situation where the first parameter is less than the second parameter.

[0077] Reference Figure 2 In the present invention, the stop signal light 1 integrates a lighting fixture and a monitoring system. The monitoring system inside the stop signal light 1 includes a power conversion module and a power line carrier communication module. Figure 2One of the power conversion module and the power line carrier communication module of the stop row of lights 1 is exemplarily shown. The power conversion module is used to convert alternating current into direct current to supply power to the low-voltage DC circuit inside the monitoring system. For example, a microprocessor unit MCU is provided inside the monitoring system. The power line carrier communication module of the monitoring system conducts power line carrier communication with the stop row of lights control system. The stop row of lights monitoring system sends a control signal to the stop row of lights 1 through power line carrier communication. The control signal indicates in what mode the stop row of lights 1 emits light (for example, constant red light, constant yellow light, flashing yellow light). The stop row of lights 1 can also send the current state of the stop row of lights 1 to the stop row of lights control system through the power line carrier communication module.

[0078] Multiple stop rows of lights 1 are connected in series in the same AC circuit through a transformer 2.

[0079] The present invention does not limit the internal structure of the stop row of lights 1, and it can be designed according to existing lamps. For example, the lamp monitoring system disclosed in CN116915285B, the carrier modulation circuit, the navigation aid lamp, the monitor, the communication host and the communication loop disclosed in CN117478472B, the switch control circuit, the single lamp monitoring device, the lamp and the system disclosed in CN118474966A.

[0080] Two types of lamps of different colors are provided in one stop row of lights 1, and each type of lamp is independently controlled to turn on and off.

The memory stores a program, and the processor runs the program to execute the above method.

[0085] In some embodiments, the airport inter-field information fusion system and the stop bar light control system both communicate with the taxiway and lane intersection safety control server via optical fiber, and the stop bar light control system and the stop bar lights communicate via power carrier.

[0086] Figure 3 Each stop bar control system controls multiple stop bars in the same AC circuit. Different stop bar control systems are in different AC circuits.

[0087] Combination Figure 2 and Figure 3 The warning signal is sent by the taxiway and lane intersection safety control server to the stop light control system. The stop light control system can also send a warning signal to the warning system, such as a voice warning system, which reminds the vehicle driver to pay attention to the danger by issuing a voice warning.

[0088] The warning signal can also be sent to the vehicle by the taxiway and lane intersection safety control server through the wireless network, and the vehicle sends a voice warning to the driver.
