The mobile phone RF-SIM card “mobile phone card” integrated management system adopts the most advanced 2.4G technology in the world. The introduction of this system has brought great convenience to the management of the society, colleges and universities, and has caused great repercussions.
At present, in universities and colleges, the management of a large number of personnel’s certificates, files, and canteen sales are not related, and there is no mutual connection between various departments, resulting in waste of manpower and financial resources, and low work efficiency. The IC card series management system can integrate the certificates of the faculty and students of the colleges and universities (including the faculty and staff ID, student ID, library card, access card, etc.), student registration file management, faculty and staff attendance, canteen management, computer room management , Parking lot, swimming pool management, commissary and other small consumption functions are integrated into one card, so that colleges and universities can get rid of the cumbersome and inefficient management style, and devote more energy to scientific research and study.
Design Principles
The design of this program is based on the actual requirements of the campus, in line with the principles of scientific and reasonable, economical, practical, advanced and reliable, and compatible with strong expandability.
Advanced
This system is designed with full consideration of the advanced nature of equipment and technology. This system adopts 2.4G RF-SIM card and non-contact IC card (8K memory, IC chip can be read and written), and its storage structure allows the card to be used in multi-application systems. There are as many as sixteen different applications, freeing managers from cumbersome management methods, while allowing users to feel its speed, convenience and ease.
Good scalability
We have fully considered the scalability of the system’s capacity increase:
1. The network design adopts the bus system, and all equipment management hosts are hung on the bus. When the system is increased in the future, only the management equipment needs to be directly connected to the bus, without the need to modify the line;
2. The system application software can support the use of 100,000 cards, which can fully meet the needs of future personnel growth;
3. One card, one database, one network, one platform.
4. The use of a non-contact smart card system to realize campus canteen charges, book borrowing, computer charges, commissary charges, bathhouse charges, gymnasium charges, hospital charges, club charges, a one-card integrated management system. The effective distance of the induction zone of the toll machine can complete the consumption. Eliminates the various drawbacks that may occur in the old consumption mode, that is, speeds up the operation, improves the consumption mode, strengthens the security of the system, and is conducive to intelligent management. The network design adopts the bus system, and all equipment management hosts are hung on the bus. When the system is increased in the future, only the management equipment needs to be directly connected to the bus, without the need to modify the line;
System safety and reliability
All terminal devices of smart card products are single-chip microcomputers with microprocessors and memories to ensure the accuracy of data calculation and the integrity of data storage; the IC card adopts the M1 type logical encryption memory card of PHILIPS company, with a 32-bit unique serial number in the world. , To prevent copying, the card can be triple-encrypted, which has stronger security and stability than magnetic cards and ID cards that require real-time networking.
The upper-level management software of the system runs on the existing enterprise or campus LAN, and each terminal device is connected to a workstation near the LAN. All cards are issued uniformly after the management center establishes the personnel data. If there is a personnel data software before, the original database data can be called without having to re-enter it. The consumption data is collected by each management workstation and then transmitted to the server, and the statistics of each report are generated through the management workstation accessing the server database.
All-in-one card platform design instructions
Section 1. Overview:
The one-card system is a mobile phone card-based application system developed around the needs of enterprises. The system builds a series of application subsystems in a modular manner on the basis of the one-card (cartoon, Kutong, Netcom) platform, allowing users to implement a single Application systems (such as attendance systems) can also implement multiple application systems or all-round one-card systems at the same time or step by step.
When a user expands from a single application system to multiple application systems or a full-scale one-card system, there is no need to replace the cards and devices that have been used in applications, and only need to easily add new application modules to the implemented application platform. Greatly shorten the system implementation time and save implementation costs.
The one-card system can include the following modules:
“Personnel system”, “card management”, “access control system”, “attendance system”, “canteen system”, “patrol system”, “conference sign-in system”, “water control system”, “electricity control system”, etc. Wait.
The second section, the principle of the all-in-one card:
The one-card system is a stable, reliable, easy-to-use smart card management system developed on the basis of the three links of cards:
Cartoon (this system uses mobile phone RF-SIM card and MIFARE 1/IC card)
The data of each application subsystem on the card can be interoperable without losing the independent safety requirements of each application subsystem. The public data of each subsystem is stored in the basic information area, which can be read by each subsystem but cannot be rewritten. System-specific data are stored in a designated dedicated service data area, which can only be read and written by the subsystem, and cannot be accessed by other subsystems.
The data that needs to be exchanged between the various subsystems is stored in the data exchange area and can be called mutually. Through the establishment of basic information area, data exchange area and special service data area mechanism, the technical requirements of “cartoon” are perfectly realized. This allows a card to be issued only once and can be used in various application subsystems.
The MF1 IC card has 16 sectors, and the specific allocation of sectors can be determined according to user needs.
Kutong (this system uses SQL Server 2000 database)
Adopt large-scale distributed network database, four public databases such as personnel information, card and equipment information, console information and account set information as the bottom group of distributed database, which can be shared by N business subsystems. The dedicated information of each business subsystem (such as attendance, access control, consumption, item acquisition, etc.) is an independent second-tier database group, which not only reflects the unity of system data, but also ensures the independence of each business data. The system has more convenient function scalability, smooth version upgrade and seamless link with third-party management software.
Netcom (this system uses TCP/IP as the backbone network, and some subsystems have RS485 branch networks)
The hardware and software equipment of the all-in-one card system can be connected to form an organism through the local area network, wide area network, etc., to realize the functions of the all-in-one card system. This system integrates computers, smart card read-write terminal equipment and various application systems into a coordinated organic unity by designing a unified application layer communication protocol, using standard hardware communication interfaces, compatible with multiple networking methods such as bus, local area network, and wide area network. body.
interface
The all-in-one card system is an important part of the enterprise weak current system, which is based on the enterprise LAN. The network structure diagram of the “Enterprise One Card System” is as follows:
The third section, the basic platform foundation of the one-card card:
The hardware facilities of this system adopt a distributed structure. The various hardware units exchange data with the database server through the network (TCP/IP). Different functions can be set on different operating sites, management can be separated, and resources can be shared. The infrastructure framework is shown in the figure.
The system software is a modular structure, that is, a unified system universal entry is provided on the user side. Call each function module through this entry program. The function module processes the data in the database and returns the result to the database. There is no direct connection between the various functional modules.Because the function module is consistent with the interface specification of the general entry program, it can be very generous
Increase and decrease functions to meet the different needs of the enterprise. The system framework is shown in the figure.
The entire system can customize the required modules through customers. The optional modules above are the modules in the all-in-one card platform. These modules plus the data-synchronized parking lot system, library management system, patrol system, etc., truly realize the management of the entire all-in-one card.
The one-card system includes “personnel management”, “card management”, “access control management”, “attendance management”, “canteen management”, “parking lot management”, “book management”, “meeting sign-in management”, “water control management” “, “Power Control Management” and other functional modules. At present, the systems involved in this project include: personnel management, card management, access control management, attendance management, canteen consumption and other modules. Now the module functions involved in this project are introduced as follows .
