ISBN 978-952-5726-09-1 (Print) Proceedings of the Second International Symposium on Networking and Network Security (ISNNS ’10) Jinggangshan, P. R. China, 2-4, April. 2010, pp. 230-233 Design of Electron-agriculture System Base on Information Visualization and Windows Live Platform Meiyu Zhang, and Fengfan Zou Zhejiang University of Technology, Hang Zhou, China zmy@zjut.edu.cn Zhejiang University of Technology, Hang Zhou, China zfftxwd@163.com Abstract—In order to solve our country existing agricultural information system defects: such as function sole, interactive poor, difficult for users to operation, as well as the information resources is sole and redundant. The paper has developed an so-called electron-agriculture system using information visualization technology, electronic geography information technology, Visual C#.NET, Silverlight, and SQL Server. The design simplifies the user operation, friendly human-machine interface and involved in interaction. A. System function The system mainly has four modules. As shown in Fig.1. Index Terms—information visualization, windows live, silverlight, electronic geography information technology I. INTRODUCTION Taking into account the main user is farmers, and the farmers do not well in using complicated PC and surfing the Internet, while the traditional systems had not considered this problem, leading to the farmer have not enough enthusiasm to participate in countryside informatization. So the design of the Electron-agriculture system based on Windows Live platform and information visualization mainly consideration the man-machine interface functions, and the business function of traditional system operation is replaced by virtual earth and google earth to come true. By using the technology of information visualizing users use simple 、intuitive and other easy operate ways, such as using mouse to click, to use this system. User doesn’t need to have the professional knowledge of geographic information, can be surfing Internet to view agriculture informations, such as space information, graphics and pictures, and can use the information to help users to analyze. The system realizes a four tier system structure based on B/S (browser/server). The whole system should have good expansibility and commonability, so it is convenient to carry on the secondary development and expand on windows live id platform that it includes virtual earth, unified user identity authentication (Live ID), online communication by Windows Live Messenger, Windows Live Search and Silverlight streaming. Combining Silverlight technology to compose the rich client, by using this technology, we will have a rich content and wonderful visual effect of flowery interactive experiences. © 2010 ACADEMY PUBLISHER AP-PROC-CS-10CN006 II. OVERALL DESIGN 230 Figure 1. The main function modules Agricultural information module can be divided into three smaller modules, agricultural information visualization module, agricultural supply management module and search module. The main function of agricultural information visualization module is view and contrast agricultural information by using silverlight that it shows an intuitive comparison through the wonderful visual effect chart. The main function of agricultural supply and demand management module is to look over and release supply and demand information. Search module mainly have supply and demand search, price search, technology search, market search and comprehensive search. Allowing users to search the entire system resources so as to quick location resources. Expert-assisted module mainly introduces various experts, on-line question and answer with experts, intelligent analysis. Interactive information through QQ and MSN. You can ask for help from expert online or send leaving message to experts. By using the technology of visual/Google earth and Silverlight to show the analysis of distribution line on the map and to show the price forecast analysis through the chart. The user management module manages the permission of system user and group management that it helpful for multi-user system management tasks. Public information module provides users with some common traditional electron-agriculture service functions,
such as weather information, technology information, links and other information. B. Design and development the platform based on Windows Live This system will use Windows Live platform for secondary development, including a lot of Microsoft's technology [3]; design scheme is shown in Fig.2. regions or markets, on the map, using different colors to indicate the relationship between supply and demand, when click on a specific region, it will use chart to display the specific data, such as the Fig.4 shows. Figure 2. system design The windows live id platform support the interface of Virtual Earth SDK to show the graphic information data, and using Google earth to show the detail information, because Google earth have a better graphics detail. Realize unified identity authentication through Live ID SDK interface, then user could login the system without registering, but also can register in the system and login in. Silverlight Stream SDK interface is used to access heterogeneous information that support streaming. The three key technologies have always been throughout the business system applications. C. Visual design on electronic agriculture information The system uses virtual/google earth map information and silverlight applications to realize information visualization Design shows in Fig.3. Figure 4. Display data through the map and silverlight chart In the left may, the red region means demand exceeds supply, blue means oversupply, green represents a considerable supply and demand. When the user doubleclick on these information points, when it will carry out various forms of graphical charts to show in Fig.5. Figure 5. Graphic chart showing You can also through the drop-down menu to choose, market, price, supply and demand, displaying mode, etc. The selection can be demonstrated as shown in the graphic charts. Judging from what has been argued above, we have come to see that the design support more interactive behavior, rich the presentation tier logic. It allows the user to achieve common dynamic data view by normal clicking operation, reducing the interruption and waiting. It is helpful for user to analysis the market, and improves the experience significantly. Ⅲ. WINDOWS LIVE PLATFORM AND SILVERLIGHT FUNCTIONAL DESIGN Figure 3. Informatization information visualization design In the agriculture information visualization design, the user through the drop-down menu that shows a certain period of time or a particular market for a product or by clicking on the virtual/google earth map information to display the data [2] [3]. Among them, visualization of agricultural product supply and demand, the different A. The application summary of the Windows Live platform in the business functions layer In order to achieve the system’s target, simplifies the operation, friendly system interface and participate interactively, we use Windows Live platform for secondary development, mainly contain three techniques, Virtual Earth, Live ID, and Silverlight stream. In addition to Internet access, there are cell phone accesses, telephone, GPS positioning and so on. At the same time, user could log in through the site registered, MSN, QQ and so on in the same access channels. The system use Windows Live ID, internet unified authentication system, and it is simply to operation and support interaction. It combines the system application 231
