[0022] The present invention and its embodiments are described below. Such description is not restrictive, and the actual embodiments are not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.

[0023] See Figure 1 , the present invention discloses an airport vehicle-free support system, which includes three major parts: a management subsystem 100, a control subsystem 200 and an execution subsystem 300. Through highly integrated information means and automation equipment, vehicle-free ground support operations at the airport are realized. The following will elaborate on the specific embodiments of this system in detail.

[0024] The management subsystem 100 is the information center of the entire vehicle-free support system, responsible for receiving, processing, storing and distributing various flight information and support data. The management subsystem mainly includes components such as a server 101, a terminal 102 and a first network switch 103.

[0025] Server 101 is the core device of the management subsystem, undertaking the important tasks of data storage, processing, and analysis. The server receives flight plans, flight dynamics, airport basic data, meteorological information, etc. from the airport information system, integrates and analyzes this information through the built-in data processing module, generates a guarantee plan, and synchronously distributes it in real time to the aircraft position controller 201 of the control subsystem 200. At the same time, server 101 is also responsible for receiving the guarantee data and equipment status information reported by the control subsystem 200, storing and analyzing this data, and providing support for the operation management and decision-making of the airport.

[0026] Server 101 adopts a high-performance hardware configuration and a stable operating system to ensure the accuracy and real-time nature of data. At the same time, server 101 also has a powerful data processing ability, can quickly respond to various data requests, and meet the needs of the efficient operation of the airport.

[0027] Terminal 102 is a computer terminal for information display, user operation, and operation and maintenance of the management subsystem 100. Terminal 102 is connected to server 101 through the first network switch 103, receives flight information, guarantee data, alarm information, etc. issued by server 101, and conducts visual display. Users can view real-time information such as flight dynamics, guarantee progress, and guarantee data through terminal 102 to understand the operation status of the airport.

[0028] Terminal 102 also provides rich operation functions. Users can modify system parameters, adjust flight plans, control the operation of aircraft positions, etc. through terminal 102 to achieve flexible management of the airport operation. At the same time, the terminal also has a historical record query function, and users can view past flight information and guarantee data at any time to provide a basis for the operation analysis and decision-making of the airport.

[0029] The first network switch 103 is the communication bridge between internal devices of the management subsystem. Through the first network switch 103, server 101 and terminal 102 can establish a stable network connection to achieve real-time data transmission and interaction. At the same time, the first network switch 103 is also connected to the second network switch 202 of the control subsystem 200 to establish a dedicated local area network for network communication to ensure unobstructed data between the management subsystem and the control subsystem.

[0030] The control subsystem 200 is the control mechanism of the vehicle-free guarantee system, responsible for receiving the flight information and guarantee plan issued by the management subsystem, and controlling the operation of the devices of the execution subsystem to complete the ground service guarantee operation. The control subsystem 200 mainly includes components such as the aircraft position controller 201, the second network switch 202, the display screen 203, and the operator control box 204.

[0031] The position controller 201 is the core device of the control subsystem. It is built-in with modules such as CPU, GPU, PLC, storage, and human-machine interface, and has powerful data processing and control capabilities. The position controller 201 is connected to the server of the management subsystem 100 through the second network switch 202, receives the flight information and support plan issued by the server, and controls the operation of the devices in the execution subsystem according to this information.

[0032] The position controller 201 can collect the data of the ground support equipment in the execution subsystem 300 in real time, such as the operating status and parameters of the power supply ground well 303, air-conditioning fresh water ground well 304, and sewage discharge and flushing ground well 305, and report this data to the server for storage and analysis. At the same time, the position controller 201 can also automatically adjust the operating status of the devices, such as starting, stopping, rising, falling, opening, closing, etc., according to the instructions of the server 101 or preset rules, realizing the automation of ground support operations.

[0033] In addition, the position controller 201 also has the remote control / local control function. In the remote control mode, users can perform remote operations on the position controller through the terminal or operator control box, realizing the remote control and management of the devices. In the local control mode, users can perform local operations through the human-machine interface of the position controller, which is convenient for on-site debugging and maintenance.

[0034] The second network switch 202 is connected to the third network switch 302 in the execution subsystem 300 to establish a dedicated local area network for network communication, ensuring unobstructed data flow between the control subsystem 200 and the execution subsystem 300.

[0035] The display screen 203 is an important output device of the control subsystem 200, which is used to display flight information, support data, alarm information, etc. to the pilots and ground crew. The display screen 203 is installed at an appropriate position within the visible range of the pilots, such as the fixed end of the position bridge or directly in front of the aircraft, facilitating the pilots and ground crew to view at any time.

[0036] The display screen 203 adopts high-brightness and high-definition display technology to ensure clear display of information under various lighting conditions. At the same time, the display screen also supports multiple information display modes, such as text, graphics, animation, etc., to meet the information display needs in different scenarios.

[0037] The operator control box 204 is the operating device of the control subsystem 200, which is used for ground crew to perform on-site operations and controls. The operator control box 204 is installed at a convenient operation position, such as directly in front of the aircraft or the fixed end of the position bridge. The ground crew can perform operations such as guiding aircraft type selection, emergency button operation, and manual support node confirmation through the operator control box.

[0038] The operator control box 204 adopts a humanized design, with a reasonable button layout and clear labels, which is convenient for ground staff to quickly operate. At the same time, the operator control box also has waterproof, dustproof, salt spray and other protection functions to ensure normal operation in harsh environments.

[0039] The execution subsystem 300 is the actual execution mechanism of the vehicle-free support system, responsible for completing ground service support tasks such as power supply, air conditioning, clean water, sewage, etc. The execution subsystem 300 mainly includes distributed I / O module 301, third network switch 302, power well 303, air conditioning and clean water well 304, sewage unloading and flushing well 305, aircraft ground air conditioning 306, aircraft ground power supply 307, clean water supply pump station 308, sewage unloading pump station 309, flushing water supply pump station 310, video camera 311, laser scanning unit 312 and other components.

[0040] The distributed I / O module 301 is a data acquisition and control device of the execution subsystem, responsible for collecting the operation data and status information of the power well 303, the air conditioning water well 304, the sewage flushing well 305 and other equipment, and controlling the operation status of these equipment. The distributed I / O module 301 is connected to the machine position controller 201 of the control subsystem 200 through the third network switch 302 and the second network switch 202 to realize real-time data transmission and interaction.

[0041] The distributed I / O module 301 adopts modular design, and can flexibly configure the acquisition and control modules according to actual needs. At the same time, the distributed I / O module also has the characteristics of high reliability and high stability, ensuring normal operation even in harsh environments.

[0042] The third network switch 302 is a communication bridge between the internal devices of the execution subsystem. Through the third network switch, the distributed I / O module can establish a stable network connection with the power well 303, the air conditioning water well 304, the sewage flushing well 305 and other devices to achieve real-time data transmission and interaction. At the same time, the third network switch is also connected to the second network switch 202 of the control subsystem to establish a dedicated local area network for network communication, ensuring that the data between the execution subsystem and the control subsystem is unimpeded.

[0043] The power well 303, air conditioning and clean water well 304, and sewage flushing well 305 are the core equipment of the execution subsystem 300, which are responsible for providing power, air conditioning and clean water services for the aircraft, as well as unloading sewage on the aircraft. These well equipment are connected to the aircraft through tunnels to achieve direct docking and service with the aircraft.

[0044] The power supply ground well 303 houses components such as power sockets and cables, which can provide a stable and reliable power supply for the aircraft. The air-conditioning fresh water ground well 304 houses components such as air-conditioning ducts and fresh water pipes, which can provide a comfortable air-conditioning environment and fresh water service for the aircraft. The sewage discharge and flushing ground well 305 houses components such as sewage pipes and flushing pipes, which can discharge the sewage of the aircraft and conduct flushing.

[0045] These ground well devices adopt advanced design concepts and manufacturing processes, featuring high reliability, high durability, etc. At the same time, the ground well devices also have protection functions such as waterproof and dustproof, ensuring normal operation even in harsh environments.

[0046] The aircraft ground air-conditioning 306 and the aircraft ground power supply 307 are special equipment for the execution subsystem, which are respectively used to provide air-conditioning supply and power supply services for the aircraft. After the aircraft is parked in place and the engine is shut down, the aircraft ground air-conditioning and the aircraft ground power supply are used for ground support.

[0047] The aircraft ground air-conditioning and the aircraft ground power supply adopt a fixed design and are usually installed near the fixed end of the jet bridge. At the same time, these devices also feature high reliability, high stability, etc., ensuring that stable and reliable air-conditioning and power services can be provided for the aircraft.

[0048] The fresh water supply pumping station 308, the sewage unloading pumping station 309, and the flushing supply pumping station 310 are water treatment equipment for the execution subsystem 300, which are respectively responsible for providing fresh water supply for the aircraft, unloading the sewage of the aircraft, and conducting flushing operations. These pumping station devices are usually installed in the terminal building and are connected to the ground well devices through pipelines to achieve the supply of fresh water and the unloading of sewage.

[0049] The fresh water supply pumping station 308 houses components such as water pumps and water tanks, which are responsible for pumping and pressurizing fresh water from the water source and transporting it through pipelines to the air-conditioning fresh water ground well to provide clean water for the aircraft. The design of the pumping station takes into account the stability of the water flow and the control of pressure, ensuring that the fresh water can reach the aircraft smoothly and meet the fresh water needs of the aircraft.

[0050] The sewage unloading pumping station 309 is responsible for transporting the sewage unloaded from the aircraft through pipelines to the sewage treatment system or the designated discharge location. The pumping station houses sewage pumps and corresponding pipeline systems, which can efficiently handle the sewage generated by the aircraft and keep the airport environment clean and hygienic.

[0051] The flushing supply pumping station 310 is used to provide flushing water for the sewage discharge and flushing ground well. After the aircraft unloads the sewage, the flushing supply pumping station will start the water pump to transport the fresh water to the flushing ground well to flush the aircraft sewage tank and sewage pipes, preventing dirt residue and blockage and ensuring the normal operation of the sewage system.

[0052] The video camera 311 is a monitoring device of the execution subsystem, which is used to monitor the operating status of the airport aircraft position and the ground well equipment in real time. The camera is installed at the fixed end of the aircraft position corridor bridge, near the ground well equipment or other key positions, and is connected to the aircraft position controller of the control subsystem through the third network switch, transmitting the real-time video signal to the display screen or terminal for the ground crew and airport management personnel to view.

[0053] The video camera 311 uses a high-definition, wide-angle lens, which can clearly capture the detailed images of the airport aircraft position and the ground well equipment. At the same time, the camera also has a night vision function to ensure normal operation at night or in low-light conditions. Through the monitoring of the video camera, the ground crew and airport management personnel can timely understand the operating conditions of the airport, discover potential safety hazards, and ensure the safe operation of the airport.

[0054] The laser scanning unit 312 is a detection device of the execution subsystem 300, which is used to detect the relative position and distance between the real-time position of the aircraft during the aircraft parking process and the aircraft stop line, preventing the aircraft from deviating and colliding during the moving process of parking at the position. The laser scanning unit is installed at the fixed end of the aircraft position corridor bridge or near the ground well equipment, and measures the distance between the aircraft and the ground well equipment by emitting laser beams and receiving reflected signals.

[0055] The laser scanning unit 312 has the characteristics of high precision and high response speed, and can measure the offset of the aircraft from the center line of the aircraft position and the distance to the stop line in real time and accurately, and transmit the measurement data to the aircraft position controller of the control subsystem through the third network switch. The aircraft position controller judges the offset of the aircraft from the center line of the aircraft position and the distance to the stop line according to the data provided by the laser scanning unit. If there is an offset, the distance is too close or there is a collision risk, the aircraft position controller will immediately issue an alarm signal and remind the ground crew and the pilot to pay attention through the display screen or terminal, ensuring the safe operation of the airport.

[0056] System working process

[0057] (1) Flight information reception and processing

[0058] The server 101 of the management subsystem 100 receives flight information such as flight plans and flight dynamics through the airport information system, and integrates and analyzes this information. The server 101 generates a support plan according to the flight information, including the specific time and requirements of support services such as power supply, air conditioning, clean water, and sewage, and issues the support plan to the aircraft position controller of the control subsystem through the first network switch.

[0059] (2) Equipment control and operation

[0060] After the position controller 201 of the control subsystem 200 receives the guarantee plan issued by the management subsystem 100, it controls the operation of the devices in the execution subsystem according to the plan requirements. The position controller 201 directly establishes connections with devices such as aircraft ground power supply, aircraft ground air conditioner, clean water supply pumping station, sewage unloading pumping station, flushing water supply pumping station, cameras, and laser scanning units, and establishes connections with devices such as distributed I / O modules, power ground well, air conditioner and clean water ground well, sewage discharge and flushing ground well, etc. through the third network switch, and sends control instructions to make the devices provide guarantee services such as power supply, air conditioning, clean water, and sewage according to the plan requirements.

The distributed I / O module collects the operation data and status information of devices such as the power ground well 303, air conditioner and clean water ground well 304, sewage discharge and flushing ground well 305, etc. in real time, and uploads this data to the position controller of the control subsystem through the third network switch 302. The position controller 201 processes and analyzes the received data to judge whether the operation status of the device is normal. At the same time, the position controller 201 also uploads the device data to the server of the management subsystem through the second network switch 202 for storage and analysis.

[0063] (4) Information display and alarm

[0064] The display screen 203 of the control subsystem 200 displays information such as flight information, guarantee data, and device status in real time for pilots and ground crew to view. If a device fails or an abnormal situation occurs, the position controller will immediately send an alarm signal and remind the ground crew and pilots to pay attention through the display screen or terminal. At the same time, the position controller will also upload the alarm information to the server of the management subsystem for recording and analysis.

[0065] (5) Remote operation and maintenance

[0066] The terminal 102 of the management subsystem 100 provides the function of remote operation and maintenance. Users can remotely operate the position controller of the control subsystem through the terminal to achieve remote control and management of the devices. At the same time, users can also view historical records, modify system parameters, adjust flight plans, etc. through the terminal, which is convenient for flexible management and maintenance of the airport operation.

[0067] System advantages and features

Through the application of information technology means and automated equipment, the vehicle-free ground support operation at the airport is realized, significantly improving the operation efficiency and safety of the airport.

[0070] (2) Intelligent management

[0071] Through the application of intelligent devices such as servers and position controllers, the system realizes the real-time collection, processing and analysis of information such as flight information, support data, and equipment status. Through intelligent management, airport management personnel can timely understand the operation status of the airport, discover potential safety hazards, and ensure the safe operation of the airport.

[0072] (3) Automated control

[0073] Through the application of automated devices such as position controllers and distributed I / O modules, the system realizes the automated control of equipment such as power supply manholes, air-conditioning fresh water manholes, and sewage discharge and flushing manholes. Through automated control, ground support personnel can easily complete ground support operations, improving work efficiency and accuracy.

[0074] (4) Visual display

[0075] Through the application of visual display devices such as display screens, the system real-time displays information such as flight information, support data, and equipment status. Through visual display, pilots and ground support personnel can intuitively understand the operation status of the airport, facilitating decision-making and operation.

[0076] (5) High reliability and stability

[0077] The system adopts high-performance hardware configuration and stable operating system to ensure the accuracy and real-time of data. At the same time, the system also has powerful data processing capabilities and remote operation functions, which can meet the needs of the efficient operation of the airport. In addition, the system also has protection functions such as waterproof and dustproof to ensure normal operation in harsh environments.

[0078] The operation method of this system is:

[0079] This system installs a server 101, a terminal 102, and a first network switch 103 in the computer room of the airport terminal building; installs a position controller 201 and a second network switch 202 in the fixed-end computer room of the aircraft boarding bridge; installs an aircraft ground power supply 307 and an aircraft ground air conditioner 306 in the safety area near the fixed end of the aircraft boarding bridge, installs a clean water supply pumping station 308, a sewage unloading pumping station 309, and a flushing water supply pumping station 310 in the terminal building, installs a power supply manhole 303, an air-conditioning clean water manhole 304, and a sewage discharge and flushing manhole 305 outside the aircraft's top-down projection, installs a third network switch 302 and a distributed I / O module 301 in the tunnels of the power supply manhole 303, the air-conditioning clean water manhole 304, and the sewage discharge and flushing manhole 305, installs a laser scanning unit 312, a display screen 203, and an operator control box 204 directly in front of the aircraft, and installs video cameras 311 directly in front of, to the left front of, and to the right front of the aircraft respectively.

[0080] The system administrator of this system performs system management operations in the control room of the computer room in the airport terminal building. The operator performs position control operations in the fixed-end computer room of the aircraft position. The ground crew operates the manholes at the parking position to complete ground support.

[0081] Under normal circumstances, this system is in an automatic operation mode. The server automatically synchronizes data to the position controller according to the flight schedule and flight dynamics. The position controller automatically executes the support plan according to the flight schedule and dynamics. The ground crew only needs to operate the manholes to complete support tasks such as aircraft power supply, gas supply, water supply, and sewage discharge. The system's position controller and server collect and record support data.

[0082] Under temporary emergency circumstances, this system is in a semi-automatic operation mode. The ground crew uses the operator control box to switch to the semi-automatic operation mode and inserts a flight for support temporarily. All support processes require manual confirmation by the ground crew.

[0083] Under abnormal circumstances of the management subsystem 100, this system is in a manual operation mode. The ground crew uses the operator control box 204 or the human-machine interface of the position controller 201 to manually input the flight schedule. The system performs support according to the manually input flight information. All support processes require manual confirmation by the ground crew. After the management subsystem 100 returns to normal, the support data is synchronized to the server for storage, so that the administrator can perform data fusion processing and historical data query.

[0084] Regardless of the operation mode, the display screen 203 of this system normally guides the aircraft to dock in position, displays the ground support status, and realizes information sharing, time synchronization, process coordination, and safety control among pilots, airport administrators, ground crew, and equipment repairmen.

[0085] It should be noted that the connection described in the present invention can be any connection method that is conducive to implementing the technical solution of the present invention, such as electrical connection, communication connection, interactive connection, etc.

[0086] Although the present disclosure has been described above with reference to exemplary embodiments, the scope of protection of the present disclosure is not limited to the embodiments described above. It will be apparent to those skilled in the art that various changes and modifications in form and detail can be made without departing from the scope and spirit of the present disclosure. The scope of the present invention is defined only by the appended claims and their equivalents.
