计算机机房管理系统的研究

时间:2015-11-22 来源:未知 编辑:电脑神童 阅读:

With the development of computer network technology, the construction of computer room in our country is becoming more and more large. This has created a good learning and working environment for school teachers and students. At present, each school has set up the knowledge of the computer system related courses, but how to achieve the effective and convenient management of computer room is still a big problem.

 

1, computer room management of the overall design concept

 

1.1, computer room management mode

 

1.1.1, centralized computer room management mode

 

At this stage, there are many new or expansion of the University's new teaching building, in the beginning of the construction has been used in a unified planning. Such in the unified planning of room management, in accordance with certain rules to arrange, to facilitate the school's unified management and post maintenance, and can implement centralized computer room management system.

 

1.1.2, distributed computer room management model

 

Some schools have been building for a long time, so the construction of computer room is relatively scattered. So on the management is also the implementation of decentralized approach. If you want to focus on these rooms, unified management, which will involve the reconstruction of the computer room, relocation and a series of problems, greatly increased the cost of management. Therefore, this kind of schools still use the decentralized management approach should be actively optimized.

 

1.2, data management mode analysis

 

1.2.1, centralized data management strategy

 

In computer room of the background data management in the most commonly used is the centralized data management, which is mainly through the use of all the data stored in the same database server, so as to realize the use of access to the computer room in the computer room for the management and control of the computer room.

 

1.2.2, distributed computer room management system strategy

 

Compared to centralized data management mode, because most schools are scattered, so there will be a lot of problems in the implementation of data management. If you are using a database server to access a database server, then the whole school data must be transmitted through the campus network, which increases the network information flow, resulting in lower speed and information security is threatened. Moreover, each computer room in the current school has its own network and connected with the campus network, but also have their own server. So at the beginning of the computer room management system design, in order to reduce the original capital investment quantity and the room of the original system, so the use of distributed management, to distribute the data to each room, to make full use of each room of its own server.

 
2, computer room management and monitoring

 

2.1, the construction of computer room of the design ideas

 

The implementation of standardized management is the fundamental for the construction of the engine room, and the upgrading and updating of equipment is the basic condition for the development of the computer room. However, due to the computer room of the mobile staff more, can not guarantee that everyone can learn how to manage the computer room in the shortest time. Therefore, this needs to establish a sound system of room management system and method, which is the engine room memo.

 

The computer room includes all the data, parameters, purchase date, documents and so on, which is the combination of traditional management and information management. Information management through the integration of heterogeneous data to achieve the management of the database, but also can use the management website to complete the query, maintenance and other work. And the traditional management is to set up a special document storage room, will be technical materials, documents, CD-ROM, etc..

 

2.2, computer running state detection

 

Problems in the detection of 2.2.1 and computer running state

 

In computer room management, it is very important to detect the running state of the computer. Master the operating state of the computer will be able to analyze the operation of the entire computer room, and to master computer memory, hard disk, CPU and other hardware use. At the same time, the analysis of computer log, network, process and so on. Can also learn from the various software to the computer's occupancy, for the upgrading of the computer hardware to provide the necessary reference. And to get the real situation, only when the computer is in use to master. However, if the computer is in use to check its running state will appear some problems. For example, the management of the back and forth to the management of the classroom teaching; when students leave the computer, may cause the operating condition of the uncertainty; if the room is more or the case, the work will be more complicated and trouble.

 

2.2.2, computer running state detection

 

In order to realize the management and understanding of the computer running state, the DNU system is used to carry on the remote maintenance of all the terminals of the engine room. The biggest advantage is that the maintenance system is only required to install on the local computer, through the input of the administrator account and password will be able to successfully complete the remote computer management and maintenance work. In the running DNU, the entire LAN is scanned, including the working group, the server, the controller and the client. When the scan is finished, the results will be displayed in the main window, and then the computer room management can realize the remote management and maintenance of all the computers in the LAN. Not only that, DNU also can realize the remote computer all kinds of information, such as the calculation of the hardware, software configuration information, system version information, display adapter information, network configuration information and the installation of repair patches, etc.. Finally, to ensure the completion of terminal services, resource sharing management, remote shutdown and other operations.

 

According to the characteristics of DNU software, two kinds of schemes of computer monitoring system are designed in this stage. First, the operation state of a designated computer to monitor the real-time, so as to facilitate the management and analysis. In other words, it is to make a IP map to any computer, and then use DNU to map the address input, so as to realize the real-time monitoring of the calculation, and analyze its running status. Second, the use of remote connection to the server to connect the various computing, and in the server terminal to install DNU and other monitoring software, so as to realize the automatic scanning of local area network, complete the running state of the whole computer. In addition, it can also use DNU to export data and carry out a unified analysis and preservation.

 

3, using UML to model the system

 

3.1, UML overview

 

In the management of computer room, at this stage, we should use a unified model language UML to carry out the system modeling. UML is a standardized graphics modeling language, which is mainly used in the analysis and design of the software. The use of UML is very wide, not only can run through the entire development cycle of the software, but also can be used for data modeling, object modeling, etc..

 
Over time, UML has actually evolved into a visual modeling language standard, and it has gradually been used as a kind of commonly used, applied and integrated graphics modeling language in the field of science and technology. So in the UML have starting from the user's perspective, and oriented object method description and modeling of the function of a software system, thus completing the description of the development process, including the demand analysis, implementation and testing. In addition, UML can also create many kinds of structural models, such as static structure or dynamic behavior structure, etc., and have some general and scalable, and of course, can be realized on a variety of systems modeling.

 

UML is a very powerful graphics modeling language, which is the most ideal tool to realize the requirement description and modeling analysis. Of course, the UML system has strong control ability for large scale, complex and large information system, and it is the most favorable tool to solve the communication barrier.

 

3.2, UML model in the computer room management system

 

In the calculation of the management system can be divided into the computer room management module, course management module, money management module and information statistics query module four modules. Which can be divided into the computer room management module for the server side and the client side of the two. Course management module main function is to achieve automatic arrangement of curriculum on the plane and displays the, also support the teacher registration, login and password modify or schedule input function; and fund management module main function is the responsible for students' personal account recharge and refund, but also to achieve to student user account, report the loss, the account information inquiry or work is computer date statistics; statistical information query module is mainly through the query to the server, of the engine room equipment to use or is curriculum information of understanding. In addition students can query their own computer time statistics and consumer use, teachers can be used in the computer room and the general course arrangement of the course to inquire about.

 

4, computer room management system design principles

 

4.1, compatibility and scalability both

 

The computer room management system should have compatibility and scalability, the purpose is to provide enough space for the day after the system upgrade or expansion. The compatibility is the same as the same time stored in the same number or not with the same brand of computer and compatible machines; scalability refers to the new equipment to increase the number of new equipment can be sufficient to ensure that there is an effect of the preparation of investment.

 

4.2, user management information standardization, unified information data format

 

Computer room management system must be the user's relevant information data and data format for a unified standard, unified management, so as to realize the data is convenient, fast management.

 

4.3, the operation is simple to understand, running to fully automated

 

In order to facilitate the management of various data analysis, statistics, query, which requires the computer room management system must be able to statistics the computer room of the machine, the charges, and the students on the machine, the basic information, operating procedures are recorded.

 

5, computer room management system

 

5.1, server side implementation

 

In order to achieve the standardization and safety of computer room management, we can design the login module.

 

The login module to the actual number of room number, and enter the account and password to enter the system, the operation.

 

In addition, when the computer is running, it will inevitably be a failure, so when a failure occurs, we should design a system to change its state, which is easy to manage.

 

5.2, the realization of the client

 

All the computers in the computer room are installed with the students, so the students enter the ID number on the computer, and can complete the upper and lower machine by the administrator. When a student is detected by a computer, the computer is locked or shut down. And the students on the computer case is all the client records. This will achieve the unified management of the engine room. Of course, the students are also able to change the password at any time to change the password, which is to prevent others from stealing their own documents and information.

 

6, the conclusion

 

Strengthen the computer room management system research and design to improve the computer management personnel and management departments work efficiency and decision-making ability has irreplaceable important role; also reduce labor costs, the computer room management more standardized, simple, scientific and efficient. At the same time, it can provide practical ideas and methods for the computer management department in the aspects of equipment procurement, computer room construction, and software management, so as to speed up the pace of China's information construction.
