In view of the research of the present situation of computer room management and the various problems in the management system, the intelligent computer room management platform is designed and implemented. Based on the present situation of computer room management in University, combined with the actual situation of computer room management, a set of efficient and scientific management system of computer room is studied. With the help of the radio frequency card, the computer administrator can realize the overall control of the computer room and carry out remote operation. The results show that the new intelligent management platform not only improves the efficiency of computer room management, but also greatly facilitates the students' use of computers. KEYWORDS Computer room management, RF card, remote control. INTRODUCTION With the continuous development of the information society, the computer room has been widely applied in all major universities and colleges, and it plays a very important role in the office of information technology on campus. Usually, the computer room bears the tasks of student practice and course teaching. The computer room has gradually become an important channel for college teachers and students to obtain effective resources, and has gradually become the core of teaching and learning in universities. Especially in recent years, with the constant attention of the state to the quality of teaching in colleges, most of them have put forward higher requirements for teaching quality, and further strengthen the scientific management and efficient utilization of computer rooms. Computer room management mainly includes personnel requirements, technical level, safety requirements and equipment management [1]. The management of computer room not only realizes the teaching of related courses, but also demonstrates the level of informatization and scientific management concept. Most colleges have their own computer room, but manual Li Zhang, @qq.com, Menglin Liu, School of Information Science and Engineering, Zaozhuang University, Zaozhuang , Shandong, China 627

2 management is still the management mode used in most computer rooms [2]. Queuing on the computer has become a common phenomenon. Computer room billing and payment methods usually use manual timing and cash. This kind of management not only lacks certain accuracy, but also brings various contradictions to the use of the bill and the cash. In the information age, this management has been unable to meet the needs of the times [3]. Therefore, at this stage, the first job of information construction in the computer room is to improve the management mode of the computer room and improve the efficiency of the operation of the computer room management. Computer room management system plays a very important role in the whole computer room management, and it has direct relationship with safety management, computer room operation and student management [4]. Based on the present situation of university computer room management and the actual situation of computer room management, it is urgent to study an efficient and scientific computer room management system. ANALYSIS AND DESIGN OF INTELLIGENT COMPUTER ROOM MANAGEMENT PLATFORM BASED ON RF CARD Requirement analysis The requirement analysis is a kind of system demand that changes the user's various requirements in a certain way to build on the computer. In the software life cycle, demand analysis is the most critical link, and it also plays a very important role [5]. Through a detailed analysis of the computer room management and machine use in a university, the system has developed a scientific implementation plan and system development methods. The following contents summarize and analyze the overall goals and tasks of the system. To manage computer login number uniformly according to student s class. Within the computer time of experimental course, if the computer room has an idle machine, then students can be allowed to pay their own fees. This method can maximize the effective use of existing resources and ensure the safety of students on the computer. To complete the management of students' time on board automatically according to the computer room management system. The student can only use his computer card to get on the computer, and the cost is deducted from the server, and the administrator only need to operate the system. The server can automatically reduce the time of students on the computer, which not only improves the management efficiency of the computer room, but also greatly reduces the work pressure of the management staff. To achieve the remote shutdown for student machines. Based on the above analysis, in the process of computer room management, more effective management methods should be adopted to improve the efficiency of computer room management and reduce the workload of computer room managers [6]. This can not only save a lot of human resources, but also reduce the consumption of material resources. To achieve the intelligent computer room management platform based on radio frequency card technology has become the inevitable requirement of the development of the information age. 628

3 Figure 1. Functional structure diagram of server. Design of server and client interface Through the analysis of the server, the system is divided into management and server-side two modules. For this reason, the function structure of the server and management are designed as follows. The server's function structure mainly includes information processing, startup server, permission setting, startup timer and data maintenance. Figure 1 shows the functional structure of the server. Network: The network consists of two parts, one is the boot timer, and the other is the startup server. The startup service means that the server has completed the initialization tasks and just wait for each client to connect with it. However, the startup timer means that the system checks the working state of the online computer every 60 minutes to check whether the online computer is in a normal working state. At the same time, the timer will follow the inspection to formulate the corresponding treatment plan. Management: Information updates are primarily intended to make changes to some of the information that may be used during the operation of the system, such as user card number, user name password, computer room number. Information statistics is to collect all kinds of information in a certain way, and the summary results are displayed in tabular form, such as the computer room sales card statistics table, students' statistics [7]. The rate setting is a kind of revision and setting for the information of student charging standard by the system management personnel. Database maintenance is to maintain the database information in a certain way, regularly backup database information, and restore the information when needed, which greatly improves the security of the database. Permission setting: Permissions settings include senior administrators and administrators. The senior administrator grants the administrator certain permissions, that is, the administrator can only access and query some clients specified by the senior administrator [8]. However, the senior administrator has the right to modify and query the information, and also has the right to restrict the client login. Database structure design This system uses Aceess 2000 to create database. This system mainly uses RF card account, administrator information and IP address table. Table 1 shows the administrator information. In the authority management module of the intelligent computer room management system, the administrator information table is very important. The senior managers can increase, modify and delete the general management authority, and grant certain authority to it. Table 2 shows user information or radio frequency card information, mainly used for registration, modification and deletion of user information. 629

RF CARD (STUDENT USER) INFORMATION. No. Field name Type and length Primary key or not Is empty Explanation 1 Kahao Char 20 Not Yes Card number 2 Mima Archer 30 Not Yes Password 3 Xueshengxuehao Char 20 Yes Not Opening time First of all, the present situation of the computer room management in a university is analyzed, and the existing management problems are put forward, and the goal of the system design is determined. At the same time, according to the system requirements, the system design scheme is proposed, and the management module and server-side module function are designed. Finally, the database is designed in detail from two aspects of concept and structure. REALIZATION OF INTELLIGENT COMPUTER ROOM MANAGEMENT PLATFORM BASED ON RF CARD Implementation of main modules on server Server startup: The startup service means that the server waits for each client to connect to the server after all initialization tasks have been done. Fig. 2 is the schematic diagram of starting service flow. Information management: Information processing refers to the analysis of the basic information, the user's card number and the password, and then summarizes the analysis according to the final result of analysis. Permission setting: Permissions settings include senior administrators and administrators. The senior administrator grants the administrator certain permissions, that is, the administrator can only access and query some clients specified by the senior administrator. However, the senior administrator has the right to modify and query the information, and also has the right to restrict the client login. When permissions are set, the advanced administrator sets the administrator's login password. When administrators log on the system, they can connect to the server as long as they enter the correct password and login name in the system. Figure 2. Flow diagram of starting service. 630

5 Realization of network communication and remote control Network communication is one of the key technologies involved in the realization of intelligent computer room management platform. Socket is used to realize network communication. Taking windows operating system as the platform to develop the system, the network communication through Winsock is achieved. Winsock controls use component forms to provide Winsock APIS to program developers. Both the Visual Basic developer or the Microsoft Access developer can use it. The administrator only needs to set the control properties to complete the writing of the server application. Thus, it can be conveniently connected with a remote computer, and also can exchange data information at the same time. That's the core of the network application. As long as we can do this, the writing of network applications can be realized. Data transfer protocol: The TCP protocol allows to build and maintain the connections between remote machines. If two computers can complete the connection, then each other can realize the data information transmission. If computer users want to build a server application, they should first create a listening port and use the Listen method. If the user computer wants to connect, then the Connection Request event will occur. The connection between computers is implemented by tuning the Accept method in Connection Request. When the computer is connected, no matter which computer can receive and send the data information. In order to complete the delivery of data information, the Send Data method can be invoked. A Data Arrival event occurs during the computer's data reception. User datagram protocol (UDP): The UDP provides only one basic data communication. User datagram protocol can only provide a non-connection service, that is, users need to find the URL information by themselves, it cannot ensure that the data information can reach the destination accurately and completely. Data notification is a data packet that starts from the data sending end and ends at the data receiving end. It is reported that UDP is usually used to the exchanges of routing tables, data and network monitoring data, and system information. Because UDP does not have three steps of TCP, the number of users cannot be successfully implemented. Of course, unlike the TCP protocol, it has many functions related to the implementation of information. The UDP belongs to a transport layer protocol, and is layered in the same way as the TCP protocol. Of course, there is a difference between the two, UDP does not provide auxiliary functions such as error retransmission and timeout retransmission. That is to say, the UDP is not reliable. Achievement of remote shutdown by API function API is the abbreviation of application programming interface. Because this system contains remote control, API function is used to realize remote shutdown. Figure 3 Remote shutdown communication process. 631

6 At this stage, Windows XP and windows 7 are the majority of the computer system. In the Windows XP system environment, users only need to call Exit Window Ex function that can quickly and easily achieve shutdown operation. But in the Windows 7 system, if the user calls the Exit Window Ex function, this operation is only canceled the computer, but cannot shutdown. The Windows 7 system can complete the shutdown operation only after obtaining the SHUTDOWN license, and the API function should be called first to obtain the SHUTDOWN license. The specific process of calling is mainly: First, the user should obtain the process handle of the current program in a certain way, and then use the acquired process handle to obtain the access token. Then, the TOKEN-PRIVILEGES framework is established and the SHUTDOWN permission is obtained. Finally, the Exit Window Ex function is used to complete the operation. In the process of implementing the system, the remote shutdown function is carried out on each management machine, and the computer room administrator can select the shutdown program according to the actual situation. Fig. 3 is the schematic diagram of remote shutdown communication process. In the implementation of remote shutdown, the modern code is longer, and it can draw on the realization process of network communication. Generally, as long as the implementation of network communication is completed, the remote shutdown of the computer can be accomplished by the API function. Usually, in the implementation process of the forced shutdown, there is always a query that hat Do you save the unsaved file?. If this prompt occurs, the user has to wait until the controlled end generates a response before switching off. However, in the specific process, students leave the computer, the computer administrator can turn off the computer. Therefore, when the system uses the shutdown function in the program, the adjustment is Exit Windows Ex. In this way, when the computer is forcibly shut down, there is no need to obtain the controlled end of the response, and the shutdown can be realized. CONCLUSION In view of the present situation of computer room management and the problems existing in the computer room management system, the intelligent computer room management platform is designed and implemented. First of all, the RF card technology is used to build the hardware environment and connect the RF reader. Then, the software system is developed and the management function is improved. In view of the various problems and defects in the computer room management, the intelligent accounting and remote operation of the computer room are realized. In order to realize the management of intelligent computer room, the RF identification technology, RF card technology and the classification and characteristics of RF card are introduced in detail. Then, the overall framework and function model of the computer room management system are described. The development of this system is based on the RF card technology. After the hardware environment has been built, the software of the system is designed and developed. The development of the main modules such as server and management machine is achieved by this system, and the test result proves that the system runs in good condition and it is reliable. After testing, the system has achieved the initial functions, and can be popularized and applied in the computer laboratory. It not only improves the management 632

7 efficiency of computer room, but also reduces all kinds of material and manpower consumed in the management of computer room. At the same time, the system greatly improves the management level of the computer room. REFERENCES 1. Duan, S., & Xu, Y. (2016).
