The induction IC card has the characteristics of high capacity, high reliability, security and anti-counterfeiting, simple operation and long life (read and write times up to 100,000 times). At the same time, the transmission rate between the reader and the inductive IC card is very high, and the average read and write time is less than 0.2 seconds, making the operation fast and accurate. The application of inductive smart card technology has brought a revolutionary change to campus management. The library management system has functions such as library management, computer time management, access control management, etc., which has a significant effect on improving the level of library management.
1. Introduction to the Library’s IC Card Management System
According to the application requirements of the library, this solution realizes the functions of library gate access control, reading room access control, book borrowing and computer management, etc. The system can be easily expanded into a campus all-in-one card system according to customer needs. After seeing the system block diagram, the modules in the scheme are briefly introduced as follows:
1. Access control management
Access control management is divided into two situations, namely the access control management of the library gate and the access control management of the reading room.
Gate access control management: When readers enter the library, they can use their IC card library card to swipe the card on the gate access control machine for verification. If it is a legal user, the access control machine will drive the barrier to release; if it is an illegal user, the access control machine will sound an alarm. The access control machine also records the personal information of the visitor.
The working process of gate passage control is as follows:

Reading room access control management: The library reading room can be divided into two categories, one is the general reading room open to all legal readers, which is not discussed; the other is the specific reading room open to specific readers, which can be passed Set the card level to solve.
When a reader enters a specific reading room, his IC card library card is swiped on the card reader in the reading room for verification. The reading room administrator confirms the reader’s authority according to the prompt of the card reader, and then enters the reading room after confirmation, otherwise it is forbidden to enter.
The working flow chart of the reading room access control machine is as follows:

2. Book management
In order to protect the original investment of the system, the borrowing management basically follows the original borrowing management module, and only needs to replace the original barcode card reader to read the barcode of the library card with the inductive IC card reader to read the IC card borrowing. Documentary evidence process.
The library borrowing process is to read the library card information through the inductive IC card reader and determine the validity of the library card. After confirming that the library card is valid, continue to read the barcode information of the book by the barcode card reader to go through the borrowing procedures, and Save the borrowing information to the back-end database.

This module involves minor modifications to the original system and requires assistance from the original system integrator.
3. Management on the machine
After swiping the card on the card reader, the reader can see the machine positions automatically allocated by the system on the card reader, or get on the machine according to the administrator’s allocation. The computer-time management computer collects card swiping information in real time and starts timing. When the computer time is up for a certain machine position, the management computer automatically prompts the administrator.

4. System management
The system management is completed by the card certificate center. The main tasks include card issuance management, blacklist management, IC card reader/writer attribute setting and data collection, etc.
If the reader’s IC card library card is accidentally lost, he only needs to report the loss to the card center in time, and the system administrator can download the blacklist from the management computer to each IC card reader to prevent the illegal use of the lost card. The lost report card can be unhooked and continue to be used.
This system’s IC card library card contains the validity period information, and the student’s IC card library card is automatically invalidated after graduation.
2. Composition of library IC card system
(1) Management Center
1. Function:
Card management (card issuance, blacklist management), IC card reader/writer attribute setting, data collection, etc.;
Data exchange with the original database in the background;
2. Hardware equipment:
1 computer above 586;
1 report printer;
1 card printer;
1 digital camera;
HD3P-KM2 type induction IC card issuer
3. Software:
Cooperate with hardware to complete the above functions and have statistical report function;
Extend a small amount of necessary data information on the original background database, including IC card reader information table, blacklist information table, card swiping flow table, transaction log table, etc.
(2) Library gate access control management
1. Function:
Channel control
Real-time monitoring (optional);
2. Hardware equipment:
Two HD3P-KM induction IC card access control machines;
2 sets of electronically controlled barriers;
1 monitoring computer (real-time monitoring-optional);
3. Software:
Front-end real-time monitoring module (real-time monitoring);
(3) Library management
1. Function: use the original function;
2. Hardware equipment:
HD3P-KM type inductive IC card reader;
Book borrowing management computer (original computer can be used);
3. Software:
&#
61623; In order to save system development costs, shorten the system development cycle, and minimize the modification of the original system. In the library management module, the above objectives can be achieved by changing the library card to verify the data source.

3. Software
Cooperate with hardware to complete the above functions.
(5) Reading room management
1. Function:
Judgment of readers’ access rights;
2. Hardware equipment:

3. Software: None
Note: Only when there is access permission to restrict the induction IC card
Considering the future expansion of the system and the convenience of connection with the campus all-in-one card system, Mifare I type passive radio frequency card is recommended for inductive IC card. Mifare I card has the following characteristics:
· Reading distance 2～4CM;
· Response time is less than 0.3 seconds;
· The number of reads and writes is not less than 100,000 times.
Three, system characteristics
This scheme is mainly designed according to the application requirements of the library, with the design principles of advanced application, investment protection, cost saving, full compatibility and scalability.
This system uses the most advanced inductive smart card technology in the world-MIFARE technology. Network communication adopts RS485/RS232 mode. The whole system has the characteristics of convenient management function, reliable anti-counterfeiting and system protection system, perfect data processing function, free stand-alone function, and powerful network expansion function.
This scheme fully takes into account the future scalability of the system and can be easily upgraded to a campus all-in-one card system. There is no doubt that the construction of a campus all-in-one card system can bring many benefits to schools.
First, simplify the daily management of the school, promote the establishment of school spirit and discipline, and greatly improve the management level and management efficiency of the school;
Second, the use of computer equipment on a large scale improves the level of school infrastructure construction and establishes a good image for the school;
Third, the daily contact of students and parents with high and new technology can form a good atmosphere, cultivate students’ interest in today’s science and technology, and play a positive role in promoting students’ learning of advanced scientific and cultural knowledge.
