On the basis of detailed analysis of the development status quo and needs of science and technology commissioners in Fujian Province, the overall framework of the service cloud platform for science and technology commissioners is constructed under the guidance of big data and cloud computing thinking. Detailed design and practical application have been carried out, which have also been applied in the selection, management and service of scientific and technological missions.

In terms of data resources, an object-oriented "dual tree structure" entity-relationship model of agricultural knowledge has been innovatively constructed. 142 thematic databases have been built according to types, including nearly 200,000 pieces of technical information; In terms of management, the platform has functions such as online selection, knowledge service, demand release, achievement docking, interactive consultation, dynamic tracking, big data analysis, etc., and realizes the online application, assessment management, performance evaluation, dynamic service. When applying for science and technology commissioners, the application of informatization has greatly improved the efficiency of registration and review. At the same time, the accumulation of points for the services of each science and technology commissioner also provides a basis for the selection of science and technology commissioners in the next year. In terms of service, it has enriched the supply methods of agricultural and rural science and technology innovation, and helped more than 5,000 science and technology commissioners in the province to provide real-time online services for the production line, effectively expanding the service scope and service depth of science and technology commissioners. The lack of "combat in the army" in the process allows science and technology commissioners with different disciplines and professional backgrounds to realize "group services" on the platform, collaboratively solve various industrial technical problems, and realize "cloud" precise services, remote services, and dynamic services, so that farmers and enterprises can obtain timely and rapid remote support from scientific and technological commissioners and teams without leaving home. In terms of service channels, Wechat Official Accounts and small programs have worked well, effectively increasing the user's viscosity.

The construction has innovated the supply and demand docking mechanism of agricultural technology, realized the "order-based" demand docking and "menu-based" service supply mode, and enabled the platform to have the functions of "technology intermediary" and "talent intermediary", preventing it from being divorced from grass-roots reality and improving service effectiveness. Also, it has provided technical support for comprehensive rural revitalization and agricultural supply-side reform. How to mine and analyze large-scale agricultural data is an important direction for the next cloud platform construction.
