On the green wheat fields, black drones hovered and sprayed mist pesticides evenly. In Bijiang District, Tongren City, Guizhou Province, rice has entered a critical period of pest control. In order to promote pesticide reduction and efficiency, Bijiang District Agriculture and Rural Affairs Bureau UAVs are used for plant protection operations throughout the region.
With the advancement of drone technology and the rapid development of related industries, drones are increasingly integrated into production and life.
The industry is developing rapidly
Aerial photography, performances, express delivery, pesticide spraying, emergency rescue... In the wave of new technologies such as 5G, artificial intelligence, Internet of Things, big data, etc., the application field of drones continues to expand and deepen.
"Compared with traditional manual knapsack or high-rod sprayer operations, drones can automatically set flight, speed, spray, and spray accurately, which can achieve the best control effect." Liu Quan, director of the Plant Protection Station of Bijiang District Agriculture and Rural Bureau Say.
Today, drones are playing a big role in agricultural production.
According to the survey data of the National Agricultural Technology Center, in 2021, there will be more than 120,000 plant protection drones operated by professional pest control service organizations, and the operating area will exceed 1.07 billion mu.
The effect of aerial plant protection unified defense is 10% to 20% higher than that of farmers' self-defense, and the utilization rate of pesticides is increased by more than 10%.
With the continuous maturity of technologies such as artificial intelligence, sensors, communications, and aviation capacity, China's drone industry has developed rapidly.
According to data released by the Civil Aviation Administration, by the end of 2021, the number of registered users of drone owners in the industry reached 781,000, and a total of 832,000 drones were registered in the industry.
The field of drone application is increasingly diversified.
At the opening ceremony of the Beijing Winter Olympics, a drone swarm consisting of 2,022 drones brought people a visual feast of light and vision; on the banks of the Yarlung Zangbo River in the south of Tibet, the staff used drones to collect images and accurately analyze the Lalin Railway. The image data of the tunnel entrance and exit effectively reduces the intensity of inspection work during the flood season, and the flood control safety is also more secure; in the Qinghai area of Qilian Mountain National Park, 40 management and protection stations are equipped with 50 patrol drones, enabling "air" patrols Monitor new patterns.
During the epidemic prevention and control period, drones also play an important role.
In April this year, Shanghai realized its first "drone dispensing".
The delivery from Jinshan Hospital Affiliated to Fudan University to the High-tech Zone, which originally took half an hour by car, took only 15 minutes to transport by drone, which not only saves time and effort, but also reduces the risk of cross-infection among volunteers.
cruise line length
Entering July, Hangzhou, Zhejiang has continuously issued orange warnings for high temperature, ensuring the safety and stability of power supply has become the top priority.
In the Pingyao area in the western part of Yuhang, where the mountains and rivers are connected and the rivers and ponds are dense, the inspection of the nearly 1,000-kilometer power supply line was once a big problem.
This summer, the first AI drone intelligent inspection center in Zhejiang Province was officially opened in Yuhang, and the inspection of power supply lines has a pair of "wisdom eyes".
According to the person in charge of the center, through the "flight control platform" of the inspection center, multiple drones can be operated simultaneously to perform tasks, and systematic safety monitoring and route management can be carried out. The "flight control platform" can also intelligently identify potential safety hazards. And self-transmission back to the background, the accuracy rate is more than 90%.
Overhead line inspection has entered the "AI era", which greatly reduces the difficulty and cost of inspection, and improves the safety and efficiency of power.
UAV is the result of the combination of traditional aviation and emerging electronic and communication technologies, and the development of the industry is mainly driven by technology.
With the rapid development of digital technology, drones are endowed with more "superpowers".
In June this year, in order to strengthen the perception capability of air cruise of all-element water traffic management, Nanjing Unicom used 5G low-altitude intelligent networking to help Nanjing Maritime Safety Administration to complete the 5G-based remote take-off and landing flight of UAVs, realizing long-distance cruise and high-definition video for the first time in the entire jurisdiction. Real-time postback.
The mission covered a 50-kilometer area from Jiangxinzhou to Xinglongzhou in Nanjing, breaking through the limitations of traditional UAV communication and endurance.
In Zhaoguang Farm, Bei'an City, Heilongjiang Province, integrated applications such as drones, Beidou navigation, remote sensing, big data and other technologies are collected through the 5G signal of the command center to the Beidahuang smart agricultural service platform to achieve "one network, one key" The new mode of digital management of "communication".
Lan Yubin, director of the National International Joint Research Center for Precision Agricultural Aerial Spraying Technology, said that drones have been closely integrated with modern technologies such as the Internet of Things, big data and cloud computing. With large-scale application, the "head goose effect" in the development of agricultural artificial intelligence has effectively promoted the development of smart agriculture.
big market demand
The "14th Five-Year" General Aviation Development Special Plan issued by the Civil Aviation Administration proposes to expand the application field of drones, guide the establishment of a market-oriented and socialized service guarantee system, and vigorously develop a new low-altitude new economy driven by new intelligent unmanned aerial vehicles. , made it clear that it will support the expansion of drone application services, deepen agricultural services, expand industrial applications, support logistics and distribution, and promote cross-border integration.
Yang Jincai, the founding president of Shenzhen UAV Industry Association, said that under the circumstance of low-altitude opening and continuous improvement of regulations, the development of the UAV industry is booming.
It is expected that the output value of the domestic drone industry will exceed 100 billion yuan this year, maintaining a rapid growth of 30%.
Tan Xiang, Secretary-General of the Research Center for UAV Application and Control of the Chinese Academy of Sciences, said that with the deepening of low-altitude airspace reform, the low-altitude economy will also develop rapidly, including UAVs and unmanned systems based on unified construction, ushering in huge business opportunities.
At present, Sichuan, Hunan, Hainan, Jiangxi and other provinces are promoting the pilot reform of low-altitude airspace management, and the low-altitude economy represented by drones is regarded as a new engine to promote economic and social development.
Yan Yuehao, Dean of the UAV Industry Technology Research Institute of Chengdu Institute of Technology, believes that in the era of digital economy, UAV companies have both opportunities and challenges.
Relevant enterprises should keep pace with the times, use emerging technologies such as big data, cloud computing, Internet of Things, blockchain, artificial intelligence, 5G communications to adjust and optimize their structures, plan high-quality development strategies, and expand aerial photography, land surveying and mapping, emergency response UAV application scenarios in the fields of rescue, agriculture, forestry and plant protection, logistics and transportation, etc., to build a multi-domain, multi-dimensional, multi-element deep integration scenario system.
Experts pointed out that, as an emerging industry, the development of the drone industry also needs the dual escort of technology and law.
It is necessary to continuously improve the supervision methods of information technology, and at the same time clarify the supervision responsibilities between different departments, form a supervision synergy, and help the drone industry and application market achieve standardized development.
