[0001] The present invention belongs to the technical field of runway intrusion prevention, and in particular relates to an airport runway intrusion prevention detection and alarm method and system. Background Art

[0002] With the development of aviation business, the number of aircraft and vehicles operating on airport grounds has increased, which has increased the pressure on airport operations and management. Once a runway incursion accident occurs, the losses caused are also very huge.

[0003] Currently, most airports rely on surface surveillance radar, video detectors, and other equipment to monitor the airport surface. However, this type of surveillance equipment requires significant initial investment and ongoing maintenance costs, cannot completely eliminate blind spots, and video detectors are susceptible to weather conditions, potentially failing to meet air traffic control requirements. Furthermore, aircraft within the airport have limited visibility, preventing pilots from timely detecting traffic conditions, making it difficult to prevent runway incursions. Furthermore, re-installing radar and video surveillance systems is challenging in some existing second- and third-tier airports. Summary of the Invention

[0008] S3: The ground sensor coil determines whether the aircraft has been detected. If the result is YES, the process proceeds to the next step. Otherwise, the process continues to determine whether the ground sensor coil has detected the aircraft.

[0009] S4, recording the initial time when each ground sensor coil detected the aircraft and the corresponding ground sensor coil number;

[0010] S5, estimating the aircraft speed, acceleration, and time it takes for the aircraft to reach the intersection of the runway and taxiway based on the information detected in step S4;

[0017] In step S5, the aircraft speed, acceleration, and time it takes for the aircraft to reach the intersection of the runway and taxiway are estimated, including:

[0018] The aircraft passes the s n-1 and s n Average velocity v between ground sensor coils n for:

[0019]

[0020] Where d is the spacing;

[0021] The aircraft passes the s n-1 and s n Acceleration a between the ground sensing coils n for:

[0022]

[0023] Where Δt is the interval time;

[0024] Assume that the intersection of the runway and the taxiway in front of the aircraft is n The distance between the ground sensing coils is l n, then the estimated time for the aircraft to arrive at the changed intersection is:

[0025]

[0026] Another object of the present invention is to provide an airport runway intrusion prevention, detection and alarm system, which implements the airport runway intrusion prevention, detection and alarm method, and includes:

[0048] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0049] The innovation of this invention lies in addressing the high operating costs and susceptibility to weather-related impacts of radar and video surveillance methods. This system utilizes ground-sensing coils, microprocessors, wireless communication, and other circuits to form an aircraft motion detection, information processing, and transmission system. This system calculates aircraft speed and acceleration, and estimates the time it will arrive at the intersection of the runway and taxiway. This system is unaffected by weather, requires minimal data processing, and provides a concise and clear runway incursion warning system. Experimental results demonstrate that this method is simple, reliable, and low-cost.

[0050] Example 1: The airport runway intrusion prevention detection and alarm system provided by the embodiment of the present invention is mainly composed of a runway intrusion detection module, a field module and a host computer monitoring module. The principle of the airport runway intrusion prevention detection and alarm system provided by the embodiment of the present invention is as follows: Figure 1 shown.

[0051] The runway intrusion detection module is used to detect changes in the inductance of the ground sensor coil loop through a detector to determine the position of the aircraft;

[0052] The field module calculates the aircraft's speed and acceleration, estimates the time it will take for the aircraft to reach the intersection of each runway and taxiway, issues a local alarm, and wirelessly transmits the aircraft's position and alarm information to the host computer monitoring module for monitoring.

[0053] The host computer monitoring module is used to connect to the field module through wireless communication, provide clock calibration for the field module, and receive runway conflict prevention and alarm information collected and processed by the field module for air traffic control personnel to manage air traffic.

[0054] Exemplarily, the runway intrusion detection module mainly includes a ground sensor coil and a detector;

[0055] The field module consists of a microprocessor, a real-time clock circuit, a local alarm circuit, and a WIFI wireless communication circuit;

[0056] The host computer monitoring module includes a host computer and a WIFI wireless communication circuit.

[0057] For example, ground sensing coil and detector. Figure 2 shown.

[0058] Ground sensing coils are circular sensors buried beneath runways and taxiways. On runways, they are evenly spaced 200 meters apart. On taxiways, they are buried 100 meters, 300 meters, and 500 meters below the runway intersection. When an aircraft or vehicle passes over the coils, a detector detects the change in inductance in the coil loop and determines the aircraft or vehicle's location.

[0059] The coil is used for data collection, and the detector is used to realize data judgment. It outputs corresponding logic signals (high or low level) according to whether there are aircraft or vehicles passing by. The principle of inductor coil sensing aircraft and vehicles is as follows:

[0060] According to electromagnetic field theory, for a solenoid coil with N turns and a length of l, a magnetic field will be generated around it, and its self-inductance is:

[0061]

[0062] Where μ ris the relative magnetic permeability of the medium; μ0=4×10 -7 h / m, A is the surrounding area of ​​the coil.

[0063] A toroidal coil and capacitor form an LC oscillating circuit, generating an electromagnetic field around the coil. When an aircraft or vehicle passes over the ground sensing coil, the iron metal on the aircraft or vehicle generates an induced current, which in turn generates a new magnetic field opposite to the original one, causing the coil's inductance to decrease. By detecting changes in the ground sensing coil's inductance, the presence of an aircraft or vehicle can be determined.

[0064] because When the inductance changes, the resonant frequency deviates from its original value, and the output is converted into a pulse through the phase-locked loop technology. When there is an aircraft or vehicle, the output is high, and when there is no aircraft or vehicle, it remains low.

[0065] For example, the microprocessor is an STM32 single-chip microcomputer, which is the core of the field module. One field module is located at each runway-taxiway intersection. The microprocessor receives the position and time of the aircraft or vehicle detected by the ground sensor coil and detector, calculates the aircraft and vehicle speed and acceleration, and estimates the time when the aircraft will arrive at each runway-taxiway intersection. It issues necessary local alarms and transmits the aircraft and vehicle position and alarm information to a host computer via wireless communication for monitoring.

[0066] Ground sensing coils are buried under the runway at intervals of d = 200m. When an aircraft passes over a ground sensing coil, a detector detects the moment when the aircraft passes over the ground sensing coil. Each ground sensing coil is coded in sequence from the start to the end of the runway, and is recorded as s0, s1, s2…s 33 During the take-off and landing process, the time when the aircraft passes through the ground sensing coil is recorded as t0, t1, t2…t 33 .

[0067] Exemplarily, the microprocessor estimates the aircraft speed, acceleration, and the time it takes for the aircraft to reach the intersection of the runway and taxiway based on the detected time when the aircraft passes the ground sensor coil, as follows:

[0068] The aircraft passes the s n-1 and s n Average velocity v between ground sensor coils n for:

[0069]

[0070] Where d is the spacing;

[0071] The aircraft passes the s n-1 and s n Acceleration a between the ground sensing coilsn for:

[0072]

[0073] Where Δt is the interval time;

[0074] Assume that the intersection of the runway and the taxiway in front of the aircraft is n The distance between the ground sensing coils is l n , then the estimated time for the aircraft to arrive at the changed intersection is:

[0075]

[0076] When the aircraft is expected to arrive at a certain taxiway and runway intersection within three minutes, the microprocessor activates the local alarm circuit and the red alarm light flashes; when the aircraft is expected to arrive at the taxiway and runway intersection within one minute, the red alarm light is always on and the alarm is activated; after detecting that the aircraft has left all the ground sensing coils at the intersection, the local alarm circuit is reset.

[0077] At the same time, the microprocessor determines whether the aircraft and vehicles are moving from the taxiway to the runway based on the order in which the ground sensor coils on the taxiway detect the aircraft and vehicles, and uploads the position information of the aircraft and vehicles moving towards the runway, as well as the operating status and warning information of the aircraft on the runway, to the host computer via the WIFI wireless communication circuit for air traffic control personnel to monitor and issue control instructions.

[0078] For example, the real-time clock circuit provides accurate time for the microprocessor, and realizes clock calibration with the host computer through the microprocessor and WIFI wireless communication circuit, ensuring that the time base of each microprocessor detecting the aircraft and vehicle passing through the ground sensor coil is consistent.

[0079] Exemplarily, the local alarm circuit uses an audible and visual alarm. A red alarm light and alarm bell are installed next to the taxiway at the intersection. Within three to one minutes of an aircraft's estimated arrival at the intersection of the taxiway and runway, the red alarm light flashes. Within one minute of an aircraft's estimated arrival at the intersection of the taxiway and runway, the red alarm light stays on and the alarm bell activates. The alarm is cleared after the aircraft passes the intersection.

[0080] Exemplarily, the Wi-Fi wireless communication circuit utilizes wireless radio frequency communication technology within the universal 2.4 GHz frequency band. The Wi-Fi wireless communication circuit is housed in both the field module and the host computer monitoring module. It transmits aircraft and vehicle operation information and alarm information detected and processed by the field module to the host computer, enabling communication between the field module and the host computer monitoring module.

[0081] For example, the host computer is an industrial control computer, placed in the tower, and connected to the field module via wireless communication to provide clock calibration for the field module. At the same time, the host computer receives runway conflict prevention and alarm information collected and processed by the field module for air traffic control personnel to conduct air traffic management.

[0082] Example 2, as Figure 3 As shown, the airport runway intrusion prevention detection and alarm method provided by the embodiment of the present invention includes:

[0083] S1, initialize the ground sensing coil and detector, and set the working mode and sampling frequency of the ground sensing coil and detector;

[0084] S2, enable the real-time clock circuit and perform clock calibration through wireless communication between the microprocessor and the host computer;

[0085] S3: The ground sensor coil determines whether the aircraft has been detected. If the result is YES, the process proceeds to the next step. Otherwise, the process continues to determine whether the ground sensor coil has detected the aircraft.

[0086] S4, recording the initial time when each ground sensor coil detected the aircraft and the corresponding ground sensor coil number;

[0087] S5, estimating the aircraft speed, acceleration, and time it takes for the aircraft to reach the intersection of the runway and taxiway based on the information detected in step S4;

[0088] S6: Determine whether the time it takes for the aircraft to reach the intersection of the runway and taxiway is less than a set value. If the result is YES, proceed to the next step; otherwise, proceed to step S3 to continue determining whether the ground sensor coil has detected the aircraft.

[0089] S7: Activate the local alarm circuit, and activate the red alarm light and alarm bell according to the time when the aircraft reaches the intersection of the runway and taxiway;

[0090] S8, detecting the operation information of aircraft and vehicles on the taxiway; detecting the operation status of aircraft and vehicles moving from the taxiway to the runway based on the ground sensing coil of the taxiway;

[0091] S9, transmits the information to the host computer, and transmits the information of aircraft and vehicles running towards the intersection on the runway and taxiway and the conditions that need to be alarmed to the host computer through wireless communication.

[0092] For example, the principle of the airport runway intrusion prevention detection alarm method provided by the embodiment of the present invention is as follows: Figure 4The present invention uses ground-sensing coils, microprocessors, wireless communication circuits, and other circuits to form an aircraft operation detection, information processing, and transmission system. It calculates the aircraft's operating speed and acceleration and estimates the time it will arrive at the intersection of the runway and taxiway. The data processing volume is small, it is not affected by weather factors, and it is low in cost.

[0093] The above description is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited thereto.
