The Ministry of Science and Technology and Chongqing Municipal People's Government co-sponsored the 13th China Chongqing Hi-Tech Fair and the Ninth China International Dual-Use Technology Exposition, which opened today at Chongqing International Conference and Exhibition Center, and Shanghai Municipal Science and Technology Commission organized 23 projects from 12 organizations to participate.

In recent years, Shanghai, according to the 19th National Congress of the People's Republic of China, has firmly implemented the strategy of military-civilian integration, dug deep into the potential of dual-use technologies with potential military applications, and enriched the database of science and technology mobilization potential, and as of March this year, more than 300 new high-tech enterprises and 4,300 dual-use technology projects have been added. The reporter saw from the exhibition site, a new generation of BeiDou navigation satellite, on-board hydrogen clock, lunar exploration project "Yutu" key technology, Mars exploration key technology, high-precision fiber optic gyro key technology and other key technologies have made major breakthroughs to support the national defense construction needs; aviation special bearings, viscous dampers, land and air amphibious vehicles, non-military and civilian technology projects. Dual-use technologies such as contact-type drugs and explosives identification have solved the technical problems in the civilian field well, and the industrialization effect is outstanding.

Military to civilian, aerospace robots help "twist the bolt."

In the welcome area of the Shanghai booth, a yellow robot is meticulously twisting a bolt, the "bolt tightening robot" brought by Aerospace Intelligence (Shanghai) Science and Technology Co. However, it is not an ordinary bolt, but a large bolt with a diameter of 10 cm long. The larger the bolt, the greater the torque to tighten the screw, the higher the precision requirements of the machine. The "screwing" technology includes a laser ranging system, visual recognition system, servo rotation, these technologies were originally integrated for spacecraft space rendezvous, now the windmill bolts provide a pipeline role of the platform.

According to the company's technical staff, the robot has been used for the four major domestic wind power group windmill assembly workshop, built a total of three production lines, equipment efficiency than manual screwing greatly improved.

The Third Research Institute of the Ministry of Public Security has brought the "air-sky and earth-integrated big data research and judgment command platform", which realizes the civilian transformation of military data such as satellite images and aerial images, and can access satellite image data such as the Jilin-1 satellite, as well as aerial data and information such as drone patrol data and monitoring data, which can be effectively promoted and applied to public security. In addition, the Government is working to comprehensively improve the ability of public security organs to use big data to control law and order and monitor key areas.

Civilian participation, energy management system for military bases

Shanghai Electric Distributed Energy Technology Co., Ltd. brings distributed energy "one-stop service" to solve the problem of how to use the most safe, rational and efficient when wind power, thermal power, photovoltaic and other energy sources are concentrated in the same grid. This technology is especially widely used in the military.

Staff cited an example, a force in the field operations during the day using fans to generate electricity, at night, the fan is closed to use the daytime energy storage power supply, this is due to the fan with too large, open noise, if the force in advance of energy planning, you can bring a number of smaller fans, then no need to close the fan at night.

Shanghai Electric Distributed Energy Technology Co., Ltd. in cooperation with the University of Berkeley, the first in China to create a precise energy planning and design, the solution can be given in a few minutes, energy efficiency can be increased up to 50%. At the same time, they use the waste lithium battery on new energy vehicles to do energy storage equipment, can make the average price of electricity by 10%, with broad prospects for development.

Sana Technology (Shanghai) Co., Ltd.'s "Sana Stereoscopic Nanofiber Mask" uses nanofiber technology with artificial blood vessels, which can be widely used in sand control, engine air filter, water filtration, nanocellulose composite materials, etc. It can also be used in military and civil protection to remove dust, bacteria, smoke and even viruses.

Shanghai and Chongqing join hands to speed up the transformation of military and civilian technologies

"Many of our institute's 3D printing technologies are exported from Shanghai," Yang Zhuangzhi, chairman of Chongqing Gonggang Zhihui Additive Manufacturing Technology Research Institute Co. said. The 3D printing institute, which has a base area of 7,000 square meters, brings together more than 20 sets of the world's top industrial-grade additive manufacturing hardware and software equipment, and in particular has signed cooperation agreements with doctors at several hospitals in Chongqing, allowing them to provide medical printing products upon request.

An orthopedic surgeon wondered if it would be possible to print a suitable ankle support for patients with foot fractures, replacing the heavy plaster cast. Ask around, Shanghai Xinjian Medical Technology Co., Ltd. "personalized diagnosis and treatment of 3D printing key technology demonstration application" project, already has this technology. With the help of the Municipal Science and Technology Commission, the technology developed in Shanghai will be exported to Chongqing, where it will be promoted, derived and incubated in the central and western markets through a joint venture with Chongqing Gonggang Zhishui Institute of Additive Manufacturing Technology.

During the exhibition, the National Technology Transfer Eastern Center and the People's Government of Banan District of Chongqing held the "Banan-Shanghai Technology Matchmaking Meeting", in which more than 20 local enterprises of Banan District had in-depth communication with the enterprises and scientific research institutions exhibiting in Shanghai, promoting a high degree of integration between the government, enterprises and scientific research institutions of the two regions, and providing a platform for the development of the technology transfer between the two regions. Multi-dimensional scientific and technological cooperation has laid a solid foundation.
