At a time when science and technology are developing rapidly and economic structure is continuously being optimized, low-altitude economy, as an emerging industry, is gradually emerging. Among them, the intelligent low-altitude system plays a vital role, becoming the core force to promote the development of the low-altitude economy, and bringing new changes and opportunities to various industries.
Definition and scope of intelligent low-altitude system
The smart low-altitude system is a comprehensive system that integrates cutting-edge technologies in multiple fields, such as advanced information technology, aviation technology, and intelligent control technology, and conducts intelligent management and coordinated operation of flight activities, infrastructure, and operational services in low-altitude airspace. It aims to improve the safety and efficiency of low-altitude flights and expand application scenarios. It covers everything from the intelligent upgrade of the aircraft itself, to the intelligent transformation of ground support facilities, to the comprehensive intelligent innovation of air traffic control command and operational management, aiming to build a safe, efficient, and convenient low-altitude flight ecological environment.
System composition analysis
1. Smart Aircraft
This is the core execution unit of the intelligent low-altitude system. In the manned field, electric vertical take-off and landing aircraft (eVTOL) are developing rapidly, such as EHang Intelligent's EH216-S, which has vertical take-off and landing and short-distance flight capabilities, and can be used in urban air commuting, emergency rescue and other scenarios. In terms of drones, DJI's many drone products are widely used in agriculture and forestry plant protection, surveying and mapping, aerial photography and other fields. They are equipped with advanced flight control systems, sensors, communication modules, etc., to achieve functions such as autonomous flight, intelligent obstacle avoidance, mission planning and execution, which greatly expands the application boundaries of low-altitude flight.
2. Low-altitude intelligent network
The low-altitude intelligent network is like the "neural network" of the system, realizing real-time data interaction and communication between aircraft and ground control centers, and between different aircraft. For example, the application of 5G technology in the low-altitude field has greatly improved the data transmission rate and stability, and can support the real-time return of high-definition images of drones and remote precision control. By building a low-altitude communication network and integrating satellite communications, ground base station communications and other methods, it ensures that aircraft always maintain stable and high-speed data connections in complex low-altitude environments, providing strong support for intelligent decision-making and collaborative operations.
3. Smart Air Traffic Control System
The smart air traffic control system is responsible for the rational allocation of low-altitude airspace resources and the orderly management of flight activities. It uses technologies such as big data and artificial intelligence to monitor and analyze the flight situation in the airspace in real time. For example, by analyzing a large amount of historical flight data and real-time meteorological data, it predicts potential flight conflicts, plans better flight routes in advance, achieves a balanced distribution of air traffic flow, improves airspace utilization, and ensures the safety and efficient operation of low-altitude flights.
4. Ground support facilities
The intelligent upgrade of ground support facilities is also critical. Smart airports (take-off and landing points) are equipped with advanced automated guidance equipment, intelligent charging (refueling) facilities, etc., which can achieve rapid and accurate docking and energy replenishment of aircraft. For example, some drone-specific take-off and landing fields can quickly complete the recovery, maintenance and preparation for take-off again of drones through automated equipment, thereby improving operational efficiency. At the same time, the intelligent transformation of ground meteorological monitoring stations, communication base stations and other facilities also provides more accurate meteorological information and stable communication guarantees for low-altitude flights.
Key technical support
1. Advanced sensor technology
Sensors are the "eyes" of aircraft to perceive the external environment. LiDAR, millimeter-wave radar, and visual sensors are widely used in smart low-altitude systems. LiDAR can accurately measure distance and three-dimensional information of the surrounding environment, which is used for obstacle avoidance and autonomous navigation of drones; visual sensors use image recognition technology to identify landmarks, obstacles, etc., to assist in flight decision-making. The fusion of multiple sensors can improve the accuracy and reliability of aircraft's perception of complex low-altitude environments.
2. Intelligent flight control technology
Intelligent flight control technology ensures that the aircraft can fly stably according to the predetermined route and respond quickly in complex environments. Advanced flight control algorithms combined with artificial intelligence technology enable aircraft to have autonomous decision-making capabilities. For example, when encountering sudden bad weather or obstacles, the flight control system can quickly adjust the flight strategy based on sensor data to ensure flight safety. At the same time, through learning and optimizing a large amount of flight data, the flight control system continuously improves flight performance and stability.
3. Big Data and Artificial Intelligence Technology
Big data and artificial intelligence technologies run through every aspect of the smart low-altitude system. In the field of air traffic control, through the collection and analysis of massive flight data, meteorological data, geographic information data, etc., artificial intelligence algorithms can achieve functions such as flight flow prediction, conflict detection and resolution, and optimize airspace management. In terms of aircraft operations, big data analysis can be used to evaluate equipment performance, optimize maintenance plans, and improve operational efficiency. In addition, technologies such as image recognition and voice recognition based on artificial intelligence can also enhance the human-computer interaction experience and lower the operating threshold.
(4) Communication Technology
In addition to the aforementioned 5G and other communication technologies, satellite communications also play an important role in smart low-altitude systems, especially in remote areas or areas where ground communication base stations are insufficiently covered. Satellite communications can ensure smooth communication between aircraft and the ground. At the same time, ad hoc network communication technology can temporarily build a communication network between multiple aircraft to achieve collaborative operations, such as information exchange when multiple drone formations perform surveying and inspection tasks.
Application scenario scanning
1. Urban transportation and logistics
With urban traffic congestion becoming increasingly serious, eVTOL is expected to become an important tool for future urban aerial commuting, enabling fast point-to-point transportation and significantly shortening commuting time. In terms of logistics and distribution, drones can go deep into remote areas or areas with inconvenient transportation to complete one-kilometer delivery tasks. For example, in some mountainous areas, drones can quickly deliver supplies, solving the problem that traditional logistics are difficult to cover.
(2) Agriculture, forestry, animal husbandry and fishery
Agricultural and forestry plant protection drones can carry pesticides, seeds, etc., and operate precisely according to preset routes. Compared with manual operation, the efficiency is greatly improved, and the harm caused by contact with pesticides can be avoided. At the same time, by carrying high-definition cameras and sensors, drones can also monitor the growth of crops and pests and diseases in real time, providing data support for scientific planting. In fish farming, drones can be used to monitor fish activities and water quality, helping to fine-tune the management of fisheries.
(3) Cultural, tourism and leisure sector
Low-altitude tourism brings a new travel experience to tourists. By taking a helicopter, hot air balloon or paragliding, tourists can enjoy the magnificent natural scenery and city landscape from the air. For example, in Zhangjiajie Scenic Area, tourists take a helicopter to overlook the strange peaks and rocks, and experience a unique visual shock. In addition, the holding of aviation sports events, such as drone racing and paragliding championships, has attracted many enthusiasts to participate, promoting the development of the cultural tourism and leisure industry.
(4) Emergency rescue field
When disasters such as earthquakes, floods, and fires occur, roads may be blocked, making it difficult for rescue workers and supplies to reach the scene quickly. At this time, drones can be the first to enter the disaster area, conduct disaster reconnaissance, and send back on-site images in real time to provide a basis for rescue decisions. At the same time, they can carry emergency supplies, such as food and medicine, and deliver them to the affected people. Helicopters can undertake tasks such as personnel rescue and large equipment transportation, playing a key role in emergency rescue.
5. Urban management
Drones are equipped with thermal imagers, high-definition cameras and other equipment, and can be used for urban illegal construction inspections, environmental pollution monitoring, power line inspections, etc. In illegal construction inspections, drones can quickly detect illegal construction activities and improve urban management efficiency; in environmental monitoring, they can monitor air quality, river pollution, etc. in real time, providing data support for environmental protection.
