Windows thin client at the grassroots level of shared engineering

Paper Keywords: windows terminal, thin clients, PC, Cultural Information Resources Sharing Project
Abstract: Application of a new generation of terminals has been limited to banking, securities, and electric power industries, it security, manageability and ease of operation and so gradually growing number of industry awareness. In explaining windows thin client characteristics of terminal equipment based on the analysis of the basic feasibility of the use of their sub-centers, and primary sub-centers of the windows thin client model was constructed discussion.


1 windows thin client
In summary windows thin client is an independent power supply with no hard disk system. by the input devices such as keyboard, mouse, smArt card readers, etc. and output devices such as monitors, printers, speakers and other components. its role The first device to receive input and exchange of Information transmitted to the server, the second is to receive the message server and output to external devices. the entire system is a terminal server (or server group), through a modem or local area network connected with them. thin client does not process Information, all the operations are done by the server. So the client configuration can be lower. windows thin client to the current stage, widely used in finance, postal services, telecommunications, taxation, public security, etc. , because of its high security, easy to poisoning, easy to manage, fewer people vote early, long service life, the past, PC as the main equipment of libraries, is now gradually teaching, bibliographic Information, reading room management, office systems such as the use of them. I believe that is also suitable for thin client windows Cultural Information Resources Sharing Project primary use.

2 basic feasibility of the Application of sub-centers
2.1 PC machine with windows thin client Comparison
At present most of the provinces and sub-centers are based on the primary client / server (Client / Server), which is basically the client PC. The advantage is the scalability of a good pc, the user high flexibility; shortcomings is the lack of security protection pc, prone to hackers, because pc high degree of flexibility, users can freely download or install your favorite software, easily download or installation process the virus into the network, resulting in cross-virus infection, and the high cost of network maintenance. In addition, due to scattered primary sub-centers, the lack of network monitoring, and some called the cultural information resources sharing project service point, actually accomplishing the bar, making the primary sub-centers lost their services. Also, the primary point of service funding shortages, inadequate funding, professional plaque serious lack of network technicians, far from meeting the daily maintenance of electronic reading and normal operation. the introduction of primary sub-center windows thin clients, able to avoid the existing PC, inadequate.

2.2 Feasibility Analysis
Cultural Information Resources Sharing Project and means of Application of modern science and technology, the Chinese Culture and information resources, digital processing and integration, through the sharing of engineering network system to satellite network, Internet, cable TV / digital TV network, mirror, removable storage, CD-ROM way to achieve outstanding cultural information resources sharing in the country, is a cultural project Huimin Hui States. The project is funded by the Ministry of Finance for financial support from the Ministry of Culture organized and implemented. Sharing Project a few years to get The results are great, but there are improvements in the service mode places, such as the introduction to the grassroots level windows thin client to run sub-centers, can achieve a multiplier effect.

(1) safety analysis. Windows thin client is a high security one of its characteristics, and cultural information resources sharing project to provide the services are mainly e-books, theater Arts, lectures, film shows, agricultural science and technology, rural production Life and other digital resources; services mainly for rural areas, local communities, ordinary people; service goal is to strive to achieve by 2010 the total number of resources 100TB, 5 ���� e-books; service measures is to build an advanced technology system to improve services , increase publicity and promotion, strengthening the building of professional teams. Cultural Information Resources Sharing Project construction and development in the country's resources, more rapid, as of July 2008, the national center to provide resources to the national total to 13.6 TB. including audio and video program 16151 (set), including the 1104 field opera theater, 603 movies, animation set in 1928, 3055 lectures, 6420 sets of agricultural feature films, 870 opera comic sketches, 300 minority language, Culture, feature films collection 1111, 15 field acrobatics, variety shows 526 games, 143 episode TV series, etc.; music program 359 (set), based mainly on traditional Chinese music, a multimedia resource library 49, through maps, text, music, videos and other methods vividly demonstrated in the form of flash pages such as the Chinese film, Chinese dance, Chinese garden, Chinese cArtoons, murals and other cultural knowledge of China; 32,555 kinds of electronic books, about 2.97 million to farmers in need-based e-books, including literary history, Art appreciation, planting and breeding technology, urban workers training, medical care, common sense policies and regulations, the basic reference books and so on. In addition, selection of the Mongolian, Tibetan, Korean, Uygur, Kazakh and other ethnic minority languages of five books, the Olympic theme books and so on. 3404 kinds of electronic journals, 5070000. collection of agricultural technology, rural economic management, agriCulture policies and regulations and other aspects of journal Articles. sharing project is rich in resources and a large number of coverage wide, grass-roots operation requires sub-centers Good security and confidentiality for the protection of a strong system, but is currently used PC, the lack of security protection. mainly in the peripheral interface management difficulties, sharing engineering resources easily steal, to drive, floppy drive, USB port, infrared substandard Let's use of behavior can not be controlled, but also easy to steal or attack by malicious, windows thin clients make up the high-security deficiencies. reposted elsewhere in the Research Papers Download http://www.hi138.com (2) life analysis. windows thin client features long life and one of its greatest. the provincial sub-centers and gradually built a number of information resources with local characteristics, a total amount of resources 52TB. such as the Shaanxi Folk Art data repository, information resources, Yunnan Agricultural library, special travel resources in Guangxi, Sichuan folk art database - Mianzhu New Year and other special sub-library of resources, would be established for the sharing of engineering services. and is still increasing year by year, largely to meet the cultural needs of ordinary people in rural areas. However, these databases are require long-term preservation, use, and follow-up, coupled with limited funding grass-roots sub-center problem, thus the need for facilities for long life protection. windows thin client machine MTBF MTBF value of up to 30 years, life expectancy is normal PC 3 - 4 times, green, low-power design (the maximum operating power is only 25W), effectively reducing the noise pollution and energy consumption.

(3) operation and management analysis. Windows thin clients easy to manage one of its other features. Cultural Information Resources Sharing Project have shown a tendency to spring up all over the end of 2008, as many as 8187, 33 central provinces, 282 prefecture-level sub-centers, 1284 sub-centers at the county level, 256 district-level sub-centers, township primary center 1893, 298 Centre Street grassroots, village primary service point of 1939, community-service points 1093, 688 schools months, 43 companies, 87 military, government agencies, institutions 270, the other 21 satellite stations a total of 2789. large number of PC machines put into operation in the management of the phenomenon of easily lead to trade-off, PC's point to point maintenance mode will cause a giant increase in maintenance effort, the introduction of thin client can avoid the lack of windows.

(4) software license cost analysis. Currently used PC, the software costs no less than the cost of the hardware, while the thin client as the client does not need to purchase and install any software, which will use the primary sub-center genuine software Computer save a considerable sum of expenditure.

3, thin-client model based on the construction of windows
windows thin client model is a new service model, is the Server / Terminal (Hong server side) mode, it is the end of the client devices such as thin client windows are used as a model. This model's basic architecture is to share engineering services to municipal point as the region receiving the information sharing project, release, storage and other central service point and information technology support points; provides services to local and regional grass-roots electronic reading; services primarily to Primary sub-centers of the National Cultural Information Resources Sharing Project and a variety of electronic resources in the region, including the primary sub-center network and equipment maintenance and technical support. windows thin client model has the following characteristics:
. Easy to use. Primary sub-centers serve primarily rural, however, the staff and not as proficient as a Computer professional, and master Computer technology is limited to a Computer or visit the sharing of engineering resources, so they terminal equipment required is simple, convenient, * easy to operate. Windows Terminal has a simple and intuitive interface, so that non-professionals can quickly grasp and use.

. Functional. The system provides downloads, Internet browsing, video, audio playback with almost all the features of PC.

. Easy maintenance. The system has good maintainability. As primary sub-centers scattered locations, the lack of professional network management personnel, are used if the client pc mode, once the equipment system crashes, the upstream network maintenance personnel often have to go back and forth across maintenance. if combined with inadequate transport facilities and personnel, it is bound to cause service disruption. and Server / Terminal (server / terminal) mode, the system uses a centralized management, so when the client device if a problem occurs, the administrator does not need to re- install, configure the machine, the server can be managed through remote management to achieve zero.

. Easy to upgrade and extensions. Application software upgrade or publish to the server side only, the client (Windows Terminal) without any hardware and software upgrades.

. Economy. The system model can minimize the hardware and software resources of the occupation, in order to reduce the tedious work of Computer management. In addition, the thin high-speed low-power CPU, and no local hard drive, a single power less than 30W, and ordinary PC single power between 240W-320W in general, so not only save electricity, but also reduce the operating costs of local service points.

. Professional. Because there is no thin client local hard disk, the system only provides downloads, Internet browsing, video, audio playback, which does not support network and local hard game, so the hardware facilities from the grassroots level to prevent sub-centers that will be the electronic reading room accomplishing the possibility of Internet cafes.

windows thin client is designed for job-intensive industries, and for uniform Application of relatively simple, you need to run high-performance computer networks and mission-critical applications to connect to a central server unit, and grass-roots operation and management of sub-centers of the basic characteristics of consistent with it, so grass-roots operation and management of sub-centers of the introduction of windows thin client model is feasible demand.
