"sharing new advantages of industrial transfer and building a new high ground for international cooperation". welcome to watch the online interview of the 2024 china industrial transfer development matchmaking event (yunnan) produced by yunnan.com.
in recent years, undertaking industrial transfer has become an accelerator of yunnan's industrial restructuring and a major driver of its transformation and development. how can we attract good industries to yunnan? in this issue, yunnan.com specially invited tang jianing, director of the yunnan provincial key laboratory of unmanned autonomous systems and dean of the school of electrical and information engineering at yunnan university for nationalities, to discuss the topic of "how can yunnan make efforts to promote the 'low-altitude economy'?"
host: "low-altitude economy" was written into the government work report for the first time in 2024. please briefly introduce what "low-altitude economy" is and what is its development status and characteristics?
tang jianing: in short, "low-altitude economy" is a new economic form that is driven by low-altitude flight activities, with low-altitude aircraft (including manned aircraft and unmanned aircraft) as the main flight carriers, radiating and driving the integrated development of related industries.
generally speaking, the "low-altitude economy" has four main characteristics: the first is that there is a large room for growth. according to the "low-altitude economy" industry research report, the market size of my country's "low-altitude economy" industry will be 2.5 trillion yuan in 2022, and it is estimated that by the end of the "14th five-year plan", the comprehensive contribution of the "low-altitude economy" to the national economy will reach 3 trillion to 5 trillion yuan, reflecting a large room for growth.
the second is the long industrial chain. the manufacturing of upstream raw materials and core equipment, such as chips, battery navigation systems, aviation coatings and other raw materials; midstream equipment manufacturing and supporting services, such as complete equipment, mission payloads, aviation maintenance and training services; downstream industry radiation applications, such as "low altitude + logistics", "low altitude + tourism", "low altitude + medical care", etc.
the third characteristic is strong integration. the "low-altitude economy" can be integrated with many industries. the upstream can be integrated with the new materials industry, the midstream can be integrated with equipment manufacturing and information industries, and the downstream can be integrated with logistics, travel, medical care, electricity and other industries. the fourth characteristic is wide radiation. because it is highly integrated, it also brings a wide range of radiation, which can radiate and drive the integrated development of manufacturing, service and other fields.
host: what challenges and opportunities does yunnan face in developing the "low-altitude economy"?
tang jianing: first of all, in terms of opportunities, yunnan's geographical conditions are mainly plateaus and mountains. under such complex geographical conditions, the demand for low-altitude flights is more urgent, providing a very rich application scenario for the development of the "low-altitude economy". at present, the upper limit of the prescribed altitude for low-altitude flights is 1,000 meters, but in actual applications, below 300 meters is the most widely used, and it is also an important space for future development. for example, "low-altitude + logistics" can greatly improve the timeliness of logistics; drone power line inspection replaces manual climbing of pole towers for maintenance, which can not only greatly reduce labor costs, but also greatly improve the safety factor and degree of standardization.
however, the "low-altitude economy" is still in its early stages of development, so there is a shortage of high-level talent in the field of "low-altitude economy"; there are still some key technologies that need to be broken through and innovatively applied in response to the characteristics and difficulties of yunnan's application scenarios. for example, yunnan's climate and terrain bring challenges to the flight environment, and the wind direction and speed in the mountainous canyon areas change dramatically, which puts very high demands on the structural stability and maneuverability of the aircraft; in addition, the support of relevant policies and management systems, as well as scenario traction, investment promotion, etc. all need to be further improved.
moderator: drones and electric vertical take-off and landing aircraft are seen as solutions to the development of the "low-altitude economy" in the future. what technical difficulties do these aircraft need to solve at this stage to better meet market demand?
tang jianing: from a technical perspective, there is no best technology, only better technology, because technology is always surpassing and breaking through. after the technical difficulties at the current stage are solved, new technical difficulties will arise. the difficulties that need to be overcome at present are generally the safety and stability of flight, as well as the problem of long-term endurance. from the perspective of promotion and application, intelligence is also one of the key technologies, including autonomous perception of the environment, automatic planning of routes, and autonomous decision-making of tasks. in addition, low-altitude flight noise reduction and reducing the impact of aircraft on people's daily lives are all key technologies that need to be solved.
moderator: what role does the key laboratory play in supporting the development of the "low-altitude economy"? what work has it done?
tang jianing: the core work of the key laboratory is definitely based on breakthroughs in key technologies and scientific and technological innovation. to borrow a phrase from academician xiang jinwu, the development of the "low-altitude economy" requires solving the problem of the role of the "eyes, cerebellum, and brain" in aviation technology.
low-altitude aircraft need to have efficient environmental perception, positioning and obstacle avoidance capabilities, and play the role of "eyes" to know where they are and what the environment is like, so as to avoid possible obstacles and interference risks; the operating environment of low-altitude aircraft is more complex and changeable, and it is necessary to break through low-altitude automatic control technology, enhance the ability of the "cerebellum", be able to respond quickly to obstacles, and ensure safe and stable flight; mission-driven aircraft must complete the transition from automatic execution of tasks to autonomous completion of tasks, which means that the aircraft's "brain" must be smarter, and must solve technical problems such as autonomous decision-making and path planning based on perception and automatic control.
currently, the work on "eyes" and "brain" are two important research directions of our laboratory. we also hope that through the laboratory's technical research, we can better promote the development of yunnan's "low-altitude economy".
the full name of our laboratory is the key laboratory of unmanned autonomous systems. the original intention of the laboratory was to solve the difficulties and pain points of the application of unmanned systems represented by drones under complex terrain conditions based on the mountainous geographical conditions of the yunnan plateau. the goal is to achieve the intelligence and autonomy, autonomous perception, and intelligent flight control of unmanned systems under complex geographical conditions. at present, the laboratory has done a lot of work scene applications in low-altitude intelligent flight, such as highway road and bridge inspections, power inspections, agriculture and forestry, and forest economy.
host: in addition to aviation technology, the development of the "low-altitude economy" also requires the joint support of "hard infrastructure" and "soft infrastructure". what are they? in addition, what else does yunnan need to do to develop the "low-altitude economy"?
tang jianing: generally speaking, it is difficult to clearly divide the support system into "hard" and "soft" aspects in the field of "low-altitude economy". they are a highly integrated "low-altitude intelligent connection system". the integration of the five networks of infrastructure network, air route network, communication and navigation network, airspace management network and low-altitude service network forms a strong support for the development of "low-altitude economy". in order for yunnan to develop the "low-altitude economy", i think it should start with overcoming the challenges it is facing now, actively implement market traction, enrich application scenarios, and under this traction, strengthen technological innovation, carry out investment promotion, and strengthen talent training. we have markets, talents, technologies, and industries, and we can better and longer support the development of yunnan's "low-altitude economy" in the future. of course, in this process, we must "establish rules". from the perspective of policies, laws and regulations and the construction of some support systems, we must gradually make the development of "low-altitude economy" more and more standardized.
