Description

Technical Field

[0001] The present invention relates to the technical field of airport safety engineering, and in particular to an active and passive combined aircraft runway arresting system and method. Background Art

[0002] Runway safety is an important part of aviation safety. Accidents such as runway overrun, runway off-touchdown and runway deviation are common in aviation accidents. These accidents not only threaten the safety of aircraft, but also seriously affect the lives of passengers. In particular, runway overrun accidents have become a major safety hazard that the global aviation industry must address. With the increase in speed and weight of modern passenger aircraft, aircraft require longer runways for safe takeoff and landing. However, many airports are unable to extend runways due to geographical restrictions, which increases the risk of runway overrun. At the same time, during landing, the aircraft may deviate from the runway centerline due to various factors (such as crosswind, equipment failure or slippery runway), resulting in the risk of lateral deviation from the runway boundary. In order to improve take-off and landing safety, the International Civil Aviation Organization (ICAO) requires airports in various countries to set up sufficiently spacious runway safety areas (RSAs), and recommends the installation of end-of-runway arresting systems (EMAS) when standard requirements cannot be met. EMAS reduces the risk of aircraft overrunning the runway by using materials that can absorb a lot of energy at the end of the runway, such as lightweight, crushable concrete blocks. These systems are similar to distress lanes on highways and stop the aircraft by pulverizing special materials to dissipate energy.

[0003] Currently, at many airports, the space at the end of the runway is insufficient to accommodate a standard-sized EMAS. Therefore, quickly and effectively intercepting aircraft that deviate laterally or overrun the runway in a limited space becomes a key technical challenge. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an active and passive combined aircraft runway arresting system and method in view of the above-mentioned deficiencies in the prior art. The aircraft runway arresting system of the present invention can arrest an aircraft that deviates laterally or runs out of the runway, and has high reliability, strong coordination and strong adaptability.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is:

[0006] An active and passive combined aircraft runway arresting system comprises an aircraft runway, a safety zone is arranged at the end of the aircraft runway, the aircraft runway arresting system also comprises a passive arresting system, an active arresting system, an integrated monitoring system and an intelligent control system, the passive arresting system is arranged in the safety zone, the passive arresting system is used for passively arresting aircraft, the active arresting system is arranged behind the passive arresting system, the integrated monitoring system is used for monitoring the speed information of the aircraft on the aircraft runway and in the safety zone, and sending the speed information to the intelligent control system, the intelligent control system is used for analyzing the speed information of the aircraft and controlling the activation of the active arresting system, and the activated active arresting system is used for arresting the aircraft after passing through the passive arresting system.

[0007] To optimize the above technical solutions, the specific measures taken also include:

[0008] The above-mentioned passive arresting system is an arresting bed, which is made of high-collapse and high-energy-absorbing materials.

[0009] The above-mentioned high-collapse and high-energy-absorbing material is a foam material or a nano material.

[0010] The above-mentioned active blocking system is an electromagnetic cutting blocker.

[0011] The above-mentioned integrated monitoring system includes a video monitoring system and a speed sensor. The video monitoring system is used to obtain aircraft video information, and the speed sensor is used to obtain aircraft speed information. Both the aircraft video information and the aircraft speed information are sent to the intelligent control system by the integrated monitoring system.

[0012] The left and right sides of the above-mentioned runway are respectively provided with side arresting systems, and the intelligent control system is connected to the side arresting system. The intelligent control system can control the side arresting system to start arresting the aircraft that runs out of the runway laterally; the side arresting system is an electromagnetic cutting arrester.

[0013] The above-mentioned active arresting system and side arresting system are respectively equipped with two independent electromagnetic cutting arresters, one of which is working and the other is used as a backup. When the aircraft runs out of the runway at a speed exceeding the set threshold, the intelligent control system can simultaneously activate the two independent electromagnetic cutting arresters.

[0014] The above-mentioned intelligent control system includes a data processing module, a risk assessment module, a decision module and a control execution module which are connected in sequence, wherein the data processing module is used to receive and pre-process data from the integrated monitoring system, perform data fusion, and form unified operating status data; the risk assessment module is used to evaluate the operating status of the aircraft based on the pre-processed data, and use a machine learning algorithm to determine whether the aircraft has a risk of deviating from the centerline of the runway or running off the runway; the decision module is used to make a decision to start the active arresting system and / or the side arresting system based on the risk assessment results, combined with the status of the arresting bed and the working condition of the arrester, to ensure that arresting measures are taken in time when there is a risk of the aircraft; the control execution module is used to execute the instructions of the decision module, control the start-up and operation of the electromagnetic cutting arrester, and adjust the electromagnetic field strength of the electromagnetic cutting arrester in real time to control the arresting strength of the electromagnetic cutting arrester.

[0015] The above-mentioned speed sensor is a laser sensor or a radar sensor.

[0016] An active and passive combined aircraft runway arresting method, using the above-mentioned active and passive combined aircraft runway arresting system, specifically comprises the following steps:

[0017] Step 1: Monitor the speed and position of the aircraft in real time through the integrated monitoring system;

[0018] Step 2: The intelligent control system receives data from the integrated monitoring system, and the risk assessment module assesses the operating status of the aircraft to determine whether the aircraft is at risk of deviating from the runway centerline or running off the runway;

[0019] Step 3: If it is determined that the aircraft is at risk of deviating from the centerline of the runway, the intelligent control system activates the side blocking system, which generates resistance to the aircraft through the electromagnetic force of the side blocking system to arrest the aircraft that deviates from the runway;

[0020] Step 4: If it is determined that the aircraft is at risk of running off the runway, the decision module calculates based on a preset algorithm whether the passive arresting system can absorb all of the aircraft's kinetic energy to stop the aircraft; if so, the control execution module does not activate the active arresting system; if not, the control execution module activates the active arresting system according to the instructions of the decision module to arrest the aircraft.

[0021] The present invention has the following advantages:

[0032] The present invention provides an active and passive combined aircraft runway arresting system, which comprises: a passive arresting system 3, an active arresting system 4, an integrated monitoring system 5, an intelligent control system 6 and a side arresting system 7; the passive arresting system 3 is an arresting bed, which is made of high-collapse and high-energy-absorbing materials such as foam materials or nano materials, and is arranged in a runway end safety zone 2, and uses the energy-absorbing characteristics of the materials to arrest aircraft rushing into the bed, wherein the nano materials can automatically adjust their own energy-absorbing capacity according to the magnitude of the impact force; the active arresting system 4 and the side arresting system 7 are both electromagnetic arresters, which are installed on both sides of the runway and at the end of the arresting bed through a fixing device, and the electromagnetic cutting arrester is composed of an electromagnetic coil, which will generate a strong magnetic field in the surrounding space after being energized, and when the aircraft enters the magnetic field range of the electromagnetic cutting arrester, the conductive material inside the aircraft will generate an induced current due to the changing magnetic field, and then generate an electromagnetic force opposite to the movement direction of the aircraft, thereby causing the aircraft to slow down.

[0033] The integrated monitoring system 5 is composed of a video monitoring system, a speed sensor, a lateral monitoring system and a multi-sensor fusion technology. The speed sensor is a laser sensor or a radar sensor. The integrated monitoring system 5 integrates the video monitoring system into the speed sensor, monitors the aircraft status through image recognition technology, and adopts multi-sensor fusion technology. It is arranged on both sides and the end of the runway to measure the running speed and position of the aircraft and convert it into an output signal, which is connected to the intelligent control system 6. The intelligent control system 6 monitors the running status of the aircraft in real time and accurately controls the electromagnetic field intensity; the intelligent control system 6 integrates artificial intelligence technology into the automatic control device, monitors the position and speed of the aircraft in real time through the speed sensor, and automatically and quickly analyzes whether the arresting bed can effectively stop the aircraft. If not, it responds quickly and starts the electromagnetic arrester to prevent the aircraft from rushing out of the arresting bed to ensure the safety of the aircraft; the active arresting system 4 and the lateral arresting system 7 are redundant, and are both arranged with two independent electromagnet systems. Under normal circumstances, the two systems work simultaneously to improve the braking force. When one system fails, the other system can independently bear all the braking force to ensure that the out-of-control aircraft can be effectively arrested in extreme cases, ensuring the safety and smoothness of the airport operation.

[0034] The intelligent control system 6 includes a data processing module, a risk assessment module, a decision-making module and a control execution module. Data processing module: receives and pre-processes data from the integrated monitoring system 5, performs data fusion, and forms unified operating status data. Risk assessment module: based on the pre-processed data, evaluates the operating status of the aircraft, and uses a machine learning algorithm to determine whether the aircraft is at risk of deviating from the centerline of the runway or running off the runway. Decision-making module: based on the risk assessment results, combined with the status of the arresting bed and the working condition of the arrester, makes a decision to start the arrester to ensure that arresting measures are taken in time when there is a risk to the aircraft. Control execution module: executes the instructions of the decision-making module, controls the startup and operation of the electromagnetic arrester, and adjusts the electromagnetic field strength in real time to achieve the best arresting effect.

[0035] The operation process of the active and passive combined efficient aircraft runway arresting system includes the following steps:

[0036] Step 1: monitor the speed and position of the aircraft in real time through the integrated monitoring system 5;

[0037] Step 2: The intelligent control system 6 receives data from the integrated monitoring system 5, and the risk assessment module assesses the operating status of the aircraft to determine whether the aircraft has a risk of deviating from the runway centerline or running off the runway;

[0038] Step 3: If it is determined that the aircraft is at risk of deviating from the centerline of the runway, the intelligent control system 6 activates the side blocking system 7, and generates resistance to the aircraft through the electromagnetic force of the side blocking system 7, thereby arresting the aircraft that deviates from the runway;

[0039] Step 4: If it is determined that the aircraft is at risk of running off the runway, the decision module calculates whether the passive arresting system 3 can absorb all the kinetic energy of the aircraft to stop the aircraft according to the preset algorithm; if it can, the control execution module does not start the active arresting system 4; if it cannot, the control execution module starts the active arresting system 4 according to the instruction of the decision module, and finally safely stops the aircraft in the safety zone 2 to prevent it from running off the runway.

[0040] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
