Large Grain Rural Integrated Service Network Management Platform

With the pace of building new countryside large agricultural country to speed up, thestate of the various policies to encourage farmers to continue farming introduced, especiallyin the provinces where the subsidized loans have introduced a new policy on rural largegrain, especially for super grain large in terms of food production insurance, warehousingfacilities, purchase of farm machinery, irrigation and other infrastructure projects given amaximum of100million preferential loan interest is good policy, but the implementationof this policy and the implementation of management using the traditional the artificiallybecome cumbersome and complex procedures, long time, large grain farmers to apply forthese loans and subsidies in the past need to prepare a lot of formalities, through layers ofapproval of the village, township, county, city, traditional manual methods give farmersapplication and approval of work brought about large grain is extremely inconvenient.The design is based. NET architecture, running on the Internet environment, toachieve a variety of subsidized loans online application large grain farmers, and village tovillage to the Internet at all levels of city approval, subsidies and loans for a variety ofinspection and acceptance, all kinds of information across large grain farmers detailedstatistical summary, while the design of large grain farmers distance education website thatprovides information on distance learning, remote video VOD, lectures, through remotevideo conferencing system to achieve agricultural experts into the classroom rural and otherfunctions.The key technique in the system1、operating style on the page using Web technology frameworkWeb technology is the framework of a WEB page design special and very importantpage design technology, its main feature is a browser screen page can be divided intoseveral parts, each part is independent and can be loaded into a web page, and in particularthe operation of any part of the screen frame in which any of the pages are linked object canspecify any one frame in the same page in the browser opens the page, the biggest benefitof this is that you can make in the same browser page web page for each frame can beopened independently of each other and coexist in the same browser page, this feature verymuch in line with operating functions in the main menu and display the page content areaused in the operation of the coexistence of the many of the network operating system fitsoperation menu page and the main display area coexist this feature, it is used in the framework of the operation of web technology design style.2、page design using AJAX technologyIn the past, the traditional page operation, when the pages of a control is operating,there will be all the contents of the entire page refresh and controls are followed, thisapproach is very unscientific, but also a waste of resources, because when the page after acertain controls are operating, may be followed by some of the controls in the page contentchanges, that followed refresh, and other controls, or content without refreshing, but thetraditional page refresh operation appeared not necessary controls and content must berefreshed once, so if you do not refresh the page once too many controls and content willincrease the burden on the server refresh, and refresh often have many of these are notnecessary, thus resulting in a waste of server resources, for this situation occursasynchronous refresh technology in recent years, which is one of the more typical AJAXrepresentatives can be achieved by this technique in a control when the page is operating,you can specify the same page in one or some of the elements followed refresh, rather thanthe whole page refreshes, such as provinces and cities and counties during the selectoperation, when the selection changes in the provinces, cities and counties have to followthe change, which is followed refresh, and other unrelated controls and content withoutrefresh, in such operations can use AJAX technology, specifically designated counties alsofollowed refresh required functions can be achieved, this approach is both efficient andrational, there are many ways to achieve the specific AJAX, and the network platform thedesign uses a VS2008.NET the most direct and concise manner that uses AJAX controlmethods to achieve.3、the use of controls to achieve the report pages print reportsThe network platform need to print a lot of reports, such as: large grain eligible todeclare the basic infrastructure Table, super large grain qualifications summary declaration,the general declaration large grain qualifications summary, more than ten kinds ofstatements, due to the large number of reports At the same format of the report is extremelycomplex, so the final choice after a detailed study of the report free web controls to designvarious report printing.4、the use of RAID technology for data storageSince the system has a large number of video-on-demand features while designing asimple video conferencing network subsystem agricultural experts, these video capabilitieson the server in response to a higher hardware requirements, so the use of RAIDtechnology to do data storage, the network platform uses four hard disks RAID0SATA interface, a data access both to improve access speed, and ensures the security of databackup.5、the use of video-on-demand server technologyProvides a platform in a number of agricultural knowledge, agricultural knowledgelearning website video, so this function of VOD video on demand technology has beenstudied mainly using Windows Media Services technology to achieve agriculturalknowledge of video-on-demand playback.6、the use of remote network video conference technologySpecifically the use of the network platform remote network video conferencingtechnology into the classroom in rural agricultural expert functions currently under modernrural environment, the computer realization of the village of broadband web, very largegrain needs in rural areas through a network of online learning to agricultural experts andremote network video consultation, so in order to meet this demand, the network platformplug-in using the free trial of third-party developers a set of basic functions of agriculturalexperts remote network video conferencing subsystem.7、the use of XML technology for data exchange with other platformsTaking into account the many data network platforms from some other system, soconsider the possibility of cross-platform systems, so the XML technology to do a carefulresearch, design some of the XML document provides data between different platformsconversion transmission while using the internal DTD defined way XML documents ofvarious design constraints.
