In 2009, he was selected into the "Excellent Talents of the Ministry of Education in the New Century" program, 20 1 1. Five consecutive International Conferences on Agricultural Computer and Computing Technology (CCTA) were organized.

In the field of scientific research and teaching, I mainly devoted myself to the research of agricultural intelligent system, focusing on the intelligent acquisition, intelligent transmission, processing and transmission and intelligent control of agricultural information, focusing on the theoretical system of agricultural intelligent system, and made the following main contributions to the field of agricultural intelligent system in terms of intelligent acquisition, intelligent processing, intelligent transmission and intelligent control of agricultural information:

(1) put forward the theoretical system of agricultural intelligent system, and published the monograph "Intelligent System-Foundation, Methods and Its Application in Agriculture", which was supported by the Academic Publishing Fund of Tsinghua University Press in 2004. This book is the main theoretical reference book engaged in the research of agricultural intelligent system at present. The agricultural expert system is extended to the agricultural intelligent system for the first time, from software to hardware, which expands the theoretical research and application field of agricultural expert system. The theoretical system of intelligent system is put forward from the aspects of knowledge representation, knowledge acquisition, knowledge discovery, database, data warehouse, knowledge base, reasoning, search and control strategy and explanation mechanism, intelligent agent and distributed system. Taking agricultural application as an example, this paper puts forward the method system of constructing agricultural intelligent system from the perspectives of development method, specification, evaluation method and mathematical algorithm of intelligent system.

(2) The methods and technologies of intelligent acquisition of agricultural information were studied. China has started the research of networked, intelligent and digital aquaculture information technology application system. He is in charge of the National 863 and Science and Technology Support Program in this field 1 1 projects, focusing on digital feature extraction technology, disease coding and automatic response technology, diagnosis model technology, consultation technology, group decision-making model and technology, and video push technology. The project has completed the system development and testing, developed the corresponding digital information collection equipment, and explored the networked expert system, call center, PDA mobile phone and remote consultation. A cotton foreign fiber detection method based on machine vision is proposed, and a cotton foreign fiber detection system based on machine vision is developed. Won the Beijing Science and Technology Progress Award, Tianjin Science and Technology Award and the Ministry of Agriculture and other four awards.

(3) The intelligent processing and transmission technology of agricultural information based on wireless network sensor and M2M technology is proposed. In the field of aquaculture, in view of the shortcomings of high cost, complex maintenance and short service life of water quality sensors, three kinds of water quality intelligent sensors and transmitters are invented by using intelligent sensing and embedded technology, which have the characteristics of intelligence, low power consumption, low cost and easy maintenance, and solve the problem that aquaculture lacks practical and reliable water quality sensors. Aiming at the problem of large area and difficult wiring in aquaculture farm, an all-wireless intelligent monitoring system for aquaculture water quality is invented by using the latest wireless sensor network technology and intelligent sensing technology, which realizes real-time dynamic monitoring of water quality and provides a data source for the application of intelligent processing system. Six invention patents have been applied for or published.

(4) The ambient intelligence control method of aquaculture agriculture is put forward, and the intensive aquaculture system is integrated and developed. Based on the principle of automatic control, the control systems of aerator and bait feeder were improved. Information system and expert system are integrated with a series of freshwater aquaculture engineering technologies such as aerator, bait feeder and portable water quality tester, forming a high-level and multifunctional freshwater aquaculture technology promotion system. Won the second prize of "research and application of information technology for intelligent monitoring and management of freshwater aquaculture" by the Ministry of Education.

(5) The China-Europe Agricultural Information Technology Research Center was established, and the research team led by it has successively won the Sixth Framework Project of the European Union and three IT projects in Asia; There are 2 C projects, 3 international key cooperation projects and 5 intergovernmental bilateral scientific and technological cooperation projects, which have established substantive cooperation relations with 20 international universities and research institutions, and become an influential academic force in the scientific and technological cooperation between China and the European Union in the field of agricultural information technology, showing strong international cooperation capabilities.

(6) Carry out extensive academic exchanges on computer agricultural applications, and organize and chair four international conferences. In 2005, he organized and chaired the second international conference on the application and innovation of artificial intelligence (AIAI2005); Since 2007, he has organized four consecutive international seminars on the application of computers and computing technology in agriculture, and served as the chairman of the conference. Since 2007, he has been an expert in the evaluation of FP7 projects in Europe. He is currently Chairman of international federation for information processing Computer Agriculture Application Committee, Director of International Federation of Information Processing Artificial Intelligence Societies, Director of International Society of Science and Engineering, Director of China Agricultural Engineering Society, Vice Chairman of Information and Information Committee, Vice Chairman of Information Technology Branch of China Animal Husbandry and Veterinary Society, Deputy Secretary-General of Agricultural Modernization Research Society of China Agricultural Society, Supervisor of Beijing Agricultural Information Society of Ministry of Education, and evaluation expert of Beijing Science and Technology Award. National 863 Plan, National Science and Technology Support Plan, National Agricultural Science and Technology Achievements Transformation Project, evaluation expert of international key cooperation projects, member of the Academic Committee of Information China, and head of the overall group of the "Twelfth Five-Year" agricultural and rural informatization planning of the Ministry of Agriculture.
