agv dynamic wireless power supply system: It is the first dynamic wireless power supply solution for smart chip factory for wafer transportation in China. It focuses on major cutting-edge scientific issues in the field of wireless power transmission, spare no effort to tackle two key technologies: dynamic wireless charging and parallel transmission of power and information, and realize mass production and commercialization of high-performance products. The system has full independent intellectual property rights, and can provide uninterrupted power supply to fast-moving cars. Because of the "Power from the Air", there is no mechanical friction, no dust, and it can be used in clean rooms having high cleanliness requirement. The development of the system has broken through the long-term monopoly of foreign semiconductor equipment manufacturers and has been promoted and applied in some domestic chip manufacturing fields, which will effectively help the security and development of the national integrated circuit industry.

Solid waste recycling 3D printing intelligent construction system: As the national first-class 3D fine printing intelligent construction equipment, it is suitable for cement mortar, concrete, geopolymer and other cement-based composite materials. The 3D printer is equipped with the self-developed 3D model slicing and printing path planning software, which can realize high design flexibility. According to the printing requirements, it can complete various area filling schemes. It is multi-model, layered and grouped slicing, suitable for different printing scene requirements. Existing 3D printing technology is mainly around the printing of 1 or 2-floor buildings. In the future, if we want to print larger-scale houses, we need to continue to develop large-scale mobile printers, platforms capable of carrying large-scale printers, and research on the structural performance of high-rise printed buildings.

Chaos enhancement and intelligent control of agitation reactor: The system adopts the industrial Internet of Things technology, and develops the first set of fluid time-varying signal acquisition and analysis terminal of rigid-flexible agitation reactor in China, which integrates online data acquisition, automatic analysis and calculation, remote monitoring and control. In order to solve the problems of poor matching of operation mode and lack of operation control and data monitoring of traditional agitation reactor, a set of fluid time-varying signal acquisition and analysis terminal for rigid-flexible agitation reactor is developed by using industrial Internet of Things technology, which integrates online data acquisition, automatic analysis and calculation, remote monitoring and regulation. The intelligent chemical agitation reactor is applied to the chemical fields such as manganese, vanadium, titanium, phosphorus, etc., and through the chaotic mixing strengthening mechanism, the product quality is improved, and the comprehensive utilization rate of resources is improved. The intelligent terminal of electrochemical equipment is applied to the pollution treatment of electrolytic manganese, coal slime and phosphogypsum, saving production energy consumption, reducing pollutant emission and realizing waste resource utilization.

Narrow linewidth laser: The narrow linewidth laser studied in this project is the first Hertzian laser with wavelength adaptive characteristics in the world. The project focuses on major cutting-edge scientific issues in the fields of precision measurement and high-speed optical communication, and spares no effort to tackle the two key technologies: laser linewidth compression and frequency stabilization. Relying on the Photonic Technology and System Research Office under the Key Laboratory of Optoelectronic Technology and Systems of the Ministry of Education, the project carries out basic and applied research on laser linewidth depth compression mechanism, functional device preparation technology and laser measuring instruments, etc. The whole chain research system from laser system to measuring instrument has developed a high-performance narrow linewidth laser with completely independent intellectual property rights.

Pair gear of large-scale solar orientation device for China's space station: The transmission project of the pair gear of large-scale solar orientation device for China's space station is the world's leading solution for solar orientation device. Facing the strict requirements of large temperature difference, large deformation, long life and high reliability in extreme space environment, the research on key technologies such as configuration principle and method of gear pair is carried out, and the key problems such as digital closed-loop precision machining and measurement of gear pair under the action of multiple physical quantities and accelerated fatigue life test technology and equipment of gear pair under virtual reality condition are solved. The life of multi-round accelerated fatigue test of prototype and positive sample products on gear is more than 30 years. The gear transmission has the adaptability to errors such as center distance change, azimuth and pitch angle change, thermal deformation, etc. The ultra-low sliding rate ensures the transmission performance and service life. The reliability of the gear transmission is guaranteed in the whole life cycle through the control of a complete set of technologies such as design theory, manufacture, detection and test.
