Through the communication facility 3.4, the command personnel can perform command work such as field personnel and material dispatching, passenger alarm, and information exchange with regulatory departments, and implement vertical take-off and landing field airspace management.

[0101] Further, the take-off and landing field comprehensive management software has a device state monitoring and control function and an auxiliary decision-making function. The device state monitoring function refers to the function of the take-off and landing field comprehensive management software to perform normal state monitoring on each support device deployed in the intelligent low-altitude vertical take-off and landing field system, to ensure that each device can work normally during aircraft take-off and landing and transfer activities. When each device fails, the take-off and landing field comprehensive management software gives an alarm prompt, and the station controller quickly notifies the maintenance personnel to repair or replace the device. The auxiliary decision-making function refers to the function of each monitoring facility to collect target data, process the collected data through the take-off and landing field comprehensive management software, automatically judge whether the current take-off and landing field safety state, airspace weather state and aircraft energy supply state meet the flight conditions, and make a prompt to the station controller. The station controller guides the aircraft to approach, take off, maintain and supply according to the prompt. The in-field operating personnel maintain the order in the station according to the indication, to ensure that the operation activities proceed in an orderly manner.

[0102] Further, referring to Figure 15 During the operation activities, the perimeter intrusion alarm system is needed to perform perimeter intrusion sensing to prevent unauthorized personnel and objects from entering the take-off and landing field restricted area, to ensure the safety of the take-off and landing field restricted area. When a perimeter intrusion occurs, the perimeter intrusion alarm system automatically identifies the intrusion behavior mode through an algorithm, classifies the intrusion behavior, and displays it in the take-off and landing field comprehensive management system, while linking the monitoring facility 3.5, automatically calling up the video monitoring of the intrusion behavior location in the take-off and landing field comprehensive management software for the station controller to confirm. Meanwhile, the station controller can issue an alarm to the intruding personnel through the communication facility 3.4, and expel them in time. Referring to Figure 16During operations, a heat and flame detection system (3.21) is required to detect heat and flames and prevent fires caused by aircraft overheating, short circuits, or human error. The heat and flame detection system (3.21) has sensors located in various modules to monitor for fires in each module. When an abnormal temperature rise or fire occurs, an alarm is displayed through the takeoff and landing field integrated management software. This triggers the monitoring facility (3.5) to retrieve the surveillance video of the affected area and activates the fire sprinkler system (1.6). After confirmation by the air traffic controller, other personnel in the takeoff and landing field are promptly notified via the communication facility (3.4) to initiate evacuation and rescue operations. During operations, a structural health monitoring system (3.22) is also required to monitor structural health and prevent extreme situations such as resonance, fatigue failure, and fracture failure of the main structure caused by earthquakes, strong winds, or high-frequency takeoffs and landings. When the structural health monitoring system (3.22) issues an alarm, the air traffic controller immediately terminates flight operations and evacuates personnel from the airfield. During operation, it is necessary to monitor basic meteorological information, atmospheric visibility, low-altitude wind field, and atmospheric electric field conditions above and around the takeoff and landing field to ensure the safe conduct of aircraft flight activities. Meteorological monitoring facility 3.3 collects meteorological information, which is then processed by the takeoff and landing field integrated management software to determine whether flight conditions are suitable. If flight conditions are not suitable, the air traffic controller promptly adjusts flight plans and notifies station personnel of flight delays and cancellations. Airspace surveillance is also required during operations, and aircraft models can be identified through surveillance facility 3.5.

[0103] See Figure 17 The integrated management software for the takeoff and landing field controls the integrated management command console 3.1, monitoring facilities 3.5, and navigation facilities 3.6 to perform arrival and departure management, specifically as follows:

[0104] The monitoring facility 3.5 receives arrival and departure reservation information sent by the aircraft to the integrated management control console 3.1; the arrival and departure reservation information includes the aircraft's identity, aircraft type, estimated arrival time, altitude, bearing, optimal takeoff and landing tilt angle, and parking time;

[0105] The integrated management and control console 3.1 provides approach guidance for the eVTOL (electric vertical take-off and landing) aircraft. It enhances the positioning accuracy of the satellite navigation system using the GNSS augmentation device 3.61, and measures the aircraft's position (azimuth, pitch, distance) using the guidance and detection radar 3.63. It compares the aircraft's actual trajectory with the preset approach route, generates a deviation correction signal, and transmits this signal to the aircraft's flight control system to adjust its flight attitude and heading, guiding the aircraft into the take-off and landing station. Finally, the aircraft identifies the parking position markings on the visual guidance facility 3.62, and the directional indicators on the visual guidance facility 3.62 adjust the aircraft's landing position to complete the landing.

[0106] The monitoring facility 3.5 provides real-time status information of the surrounding aircraft.

[0107] The takeoff and landing field integrated management software monitors the state of the guaranteeing equipment installed in each module, and also performs summary processing on safety information, weather information, monitoring information, and automatically judges whether the current takeoff and landing field safety state, airspace weather state, and aircraft energy supply state satisfy the flight conditions, to assist the station controller in decision-making.

Thus, it is intended that the present application cover the modifications and changes as they come within the scope of the claims, and their equivalents.
