Committed to innovation, he serves the country's development and construction with science and technology

In August 2020, in Fangshan District, Beijing, a "fire field" composed of four large fire spots is blazing. A combat formation composed of multiple unmanned helicopters quickly took off and headed to the "fire site" to drop fire extinguishing bombs at the fire point, accurately reached the predetermined height and position, and sprayed fire extinguishing fluid to completely extinguish the open flame. It only took less than 10 minutes from the occurrence to the end of the fire. The experts and leaders on the spot expressed their affirmation of the firefighting effect. It was the "UAV Cluster Collaborative Fire Extinguishing System" developed by the team led by Professor Lin Defu in cooperation with technology companies such as Flightwin to complete this task.

In recent years, the situation of forest fire prevention and control has become increasingly severe. The field is like a battlefield. In order to reduce the loss of personnel and property, Professor Lin Defu led the team to develop a UAV cluster collaborative fire extinguishing system, and carried out multiple rounds of optimization design and tests, and developed a UAV cluster collaborative fire extinguishing system that meets the actual combat requirements within 100 days.

The system can complete the full-process closed-loop operation of detection, perception, decision-making, and disposal in a complex environment, and has the ability to fly in formation on multiple unmanned platforms and coordinate fire extinguishing capabilities. At present, the product certification of the National Emergency Management Department has been completed, and it has been included in the Beijing Forest Fire Fighting Disposal Plan. It has been put into actual combat drills and is undergoing pilot deployment.

In addition, during the development of fire extinguishing bombs, it was discovered that traditional fire extinguishing bombs would cause certain pollution to the environment. Based on the design concept of "green, safe and efficient", the team has innovatively developed a new type of fire extinguishing bomb in cooperation with related companies, which has been practically applied in forest fire extinguishing tasks.

“Corn starch is applied as the raw material of the shell, and it can be degraded in the soil within 6-24 months. Plant protein extract is applied as the main material of the fire extinguishing fluid, and it is free of pollution. At the same time, the fire extinguishing fluid can produce "microbubbles" to isolate the air, ensuring that the ash will not reignite, and there will be no pollution to the soil.”

"Replacing manpower, liberating manpower, and enhancing manpower" is the core mission of the unmanned intelligent system, and it is also the goal of the Lin Defu’s team to transform scientific research results and achieve the strategic development of serving the country. "The application of UAV can be said to be 'boundless'. In addition to continuing to cultivate in traditional fields, we are also constantly leveraging our own advantages to innovate in high-rise fire extinguishing, agricultural plant protection, logistics, and the ability to solve operations in high-altitude areas. Research is for the long-term development of the subject, and for the cultivation of high-level talents, and for constantly gathering strength." said Lin Defu.

"How to train industry-leading leaders and talents for national key fields?" This is a question that Professor Lin Defu has been thinking and practicing. In 2015, he created a scientific and technological innovation team composed of teachers and students of Beijing Institute of Technology-the "Flying Eagle" team, focusing on cultivating students' innovative ability, team awareness and international vision on large platforms and large projects, which effectively transforms the advantages on R&D into advantages on talent cultivation. A scientific and technological innovation team of college students with diverse disciplinary backgrounds and outstanding innovative abilities came into being and gradually moved to the center of the international stage.

The "Flying Eagle" team is guided by high-level international scientific research competitions and major national needs, condensing scientific problems, and collaboratively carrying out technical research, which greatly enhances the students' frontier scientific and technological research capabilities.

In addition to participating in competitions, students of the team also actively transform the scientific and technological achievements formed in the competition into actual productivity, and serve for poverty alleviation. In recent years, Lin Defu has led a team of students to investigate and connect with poor areas such as Fuping in Hebei, Lvliang in Shanxi, Pucheng in Fujian, and Liuhe in Jilin. In response to problems such as mountainous areas and insufficient labor in poverty-stricken areas, the key technology of UAV clusters and the need for fine management of fruit forests are combined to carry out research and development of UAV cluster precision fruit forest management systems, and a fruit forest precision management system test base has been established in Liuhe, Jilin, to provide intellectual support for helping transformation and development of the regional economy.

Over the years, the team led by Lin Defu

Always face the China’s major needs

The "Flying Eagles" team won two world championships in the UAE, gaining recognition, respect, and trust. At the same time, it also attracted the attention of the heads of the UAE's education and technology departments. In 2017, Beijing Institute of Technology welcomed a new friend-Hussein Hamadi, Minister of Education of the UAE. On behalf of the UAE Ministry of Education, he extended the hand of friendship for China-UAE education and technology cooperation to BIT, and he also provided opportunities for the team to implement international development strategies.

In July 2017, the Beijing Institute of Technology-Khalifa University of Science and Technology International Joint Laboratory Construction Agreement was formally signed. Both parties will jointly carry out technical cooperation on smart agriculture, submarine oil pipeline inspection, marine exploration, human-machine integration, and unmanned driving in the fields of agriculture, climate, oil pipelines and oceans. In addition, both parties will also play the exemplary and leading role of the joint laboratory to promote all-round cooperation in science and technology, talents, and education.

In July 2017, the team went to the Khalifa University of Science and Technology in the UAE, and both parties signed a memorandum of understanding to build a joint laboratory

In November 2018, the UAE Khalifa University of Science and Technology visited BIT and signed relevant construction agreements

“It is the common scientific and technological strategic need of China and UAE to carry out research on intelligent unmanned systems. We will strive to build a world-class scientific and technological innovation platform in this field, provide strong support for the development of the national "Belt and Road" strategy, and contribute the wisdom of BIT and China's strength to the development of the countries along the "Belt and Road" route.”
