Under the guiding ideology of "promoting education modernization by informationization", the Ministry of Education has successively issued a series of guiding policies and launched a number of capital investment plans. From basic education to higher education, continuing education, teacher training, ability training and other levels to comprehensively promote information construction. The construction of educational informatization has made considerable achievements a few days ago, which has played an increasingly obvious role in promoting educational modernization.
The construction of educational informatization is based on campus network, which can be divided into teaching network, office network and intranet from physical location and logical function. Above the basic network, there are three common application platforms in campus information construction: teaching platform, management platform and information platform, among which multimedia network teaching, educational administration system, office system, financial management system, book management system and all-in-one card system are the key systems in the whole campus network construction.
At present, educational informatization has entered the application transition period. With the gradual deepening of educational informatization construction, the informatization construction of users in the education industry is gradually changing from building infrastructure platforms such as campus network to deepening application, and to driving the development of modern education with application.
The transformation of educational informatization from basic construction to application construction puts forward new requirements for the construction and managers of digital campus. On the one hand, we should improve the construction and management level of campus network. Ensure the stable and reliable operation of the whole IT system. On the other hand, it takes a lot of energy to integrate information resources, develop and build application systems, and maintain and upgrade application systems.
The purchase and configuration of computer terminals is one of the main tasks of educational informatization construction. According to the survey data of the National Bureau of Statistics, the number of computer terminals in the national education industry has exceeded100000. In the initial stage of educational informatization construction, the procurement mode of computer products is "one-time procurement, top-level configuration". However, with the accumulation of information construction experience, the current procurement pays more attention to selecting products and solutions that are conducive to strengthening lT management and information system application on the basis of ensuring cost performance.
Among all kinds of customized computer terminal solutions for users in the education industry, the solution of simplifying PC is gradually replacing the traditional PC application solution and becoming the focus of user procurement in the education industry. In the construction of digital campus, library system and electronic classroom are the key application systems of various schools. Different from computers in general enterprises and families, managers of libraries and electronic classroom systems need to face and solve the following terminal management difficulties:
Open use environment
As a public service organization, the computer terminal of the library is used in an open environment. Users of computer terminals in library reading rooms often change. Different people have different habits and ways of using computers. Users who change frequently are more likely to cause computer poisoning and computer software configuration changes. Managers need to maintain and set up computers frequently, which brings great burden to library management and is inconvenient for students and readers to use.
Cost limitation
In the construction of libraries and electronic classrooms, the cost of purchasing and using computer terminals is the main part of capital investment. Traditional PC has short life and high power consumption. Every time a computer is upgraded and maintained, it needs a lot of capital investment, and the application cost is high.
Limitation of installation space
At present, many libraries are waiting in line to get on the computer {one in and one out}, and there is no time limit for getting on the computer. More than 25% employees occupy the machine for too long (more than 3 hours), resulting in long waiting time and low utilization rate. At present, the space of the school library and electronic classroom is limited, so it is necessary to deploy as many computer terminals as possible in the limited space to meet the needs of more readers.
System upgrades and updates
With the gradual deepening of digital campus construction, PC terminals in libraries and electronic classrooms need to cooperate with the construction of school application systems to upgrade and update the systems. The traditional PC deployment scheme requires huge processing work every time the system is upgraded or updated, which greatly increases the work pressure of managers. Traditional PC has many problems, such as huge storage, high power consumption, difficult maintenance and easy loss of components, which brings a lot of inconvenience to school administrators in the construction of digital campus. HP's streamlined PC solution is a customized solution for users in the education industry according to the characteristics and needs of PC applications in the education industry. Global users in the education industry pay attention to and favor thin-client solutions in the education industry in the cloud era, which is based on the actual needs of customers in the education industry in the cloud era, and provides users with unique values and experiences in the following aspects.
