| China is a large agricultural country. The number of farmers is large, the rural area is wide, and agriculture is very important to national development. All of these make the state pay high degree of attention to "three rural". Since 2004, the central document No.l has locked in "three rural" issue 7 times, and also clearly stated on many occasions to speed up construction of rural information. Rural information is getting more and more important, and therefore speeding up rural information has become an urgent task. Due to the fact that the state attaches great importance to rural information, China's information construction in rural areas has made remarkable achievements. At the end of 2009,99.3%of the towns are connected to the internet, compared to 98%in early 2009, and 91.5%of administrative villages can surf on the internet, compared to 89%at the beginning of the year. However, although the hardware infrastructure is well, farmers still can not get the information they need simply and conveniently. Main reasons:the more expensive computer; complex computer operation, installation of software, antivirus and other required computer knowledge; weak information processing capacity of agricultural website, poor timeliness of information.To address the above problems, this project applied cloud computing technology to the information construction in rural areas, and then a cloud computing-based solution for rural information was proposed. Cloud computing is a new network service model, which changes task processing model. Desktop is the core in the traditional task processing, but now network is the core. Cloud computing uses the Internet to realize all tasks which people wish to complete, and it makes the network as integrated media which includes transmission service, Computing and information. So computing according to need and online collaboration can be realized because of cloud computing. Cloud computing technology provides a good technical support to solve rural issues. The project implementation framework is "terminal+network+Cloud Computing Center". Terminal uses embedded systems, and only simple data processing such as terminal display and Web browsing is completed in terminal. A large amount of data processing and operations are completed by the Cloud Computing Center. A new low-cost, interactive, easy to operate terminal mode is created. Network uses ADSL, fiber-optic network or wireless network to meet network requirements in different regions. Cloud Computing Center uses cloud computing technology to design information service platform. As a "brain" of rural information system, Cloud Computing Center receives mass data of different types from different regions, using data mining, artificial intelligence, and fuzzy recognition technology to process the data. And then the information farmers need is sent to the appropriate farmers. The cloud computing project realizes the leap from theory to application, and we will work hard and innovate in practice, to solve all the difficulties, promoting the improvement and perfection of cloud computing theory.In the end, this thesis has completed the design of Cloud Computing Center. The desired design goals are achieved, and the information needs of the farmers are meet. The existing program of rural information construction is improved. Construction of rural information technology provides an arena for cloud computing. With the development and promotion of the project, cloud computing will provide support to China's new socialist construction in rural areas. |
