Chapter 2 Introduction to the Enterprise One Card System
2.1 System overview
What exactly is a “all-in-one card”? What is the conceptual meaning?
Based on years of exploration and research on smart cards and the development and application of smart card management system engineering, we believe that the real “one card” concept should be “one card, one library, one line”, that is, a network line connects to a database through a comprehensive software , To realize the functions of setting, managing, querying and so on for a card. However, many system vendors are only superficially integrated systems when integrating “one card, one library and one line”. For example, manufacturers that produce consumer systems integrate library management systems, access control systems, etc., although they can guarantee that only “one card” is used, It is impossible to truly realize a common database and guarantee the use of “one database”. Instead, some data import and export functions are done in completely different sets of two or more software. This will bring a lot of trouble to the user (enterprise). For example, if an employee’s card is lost or reissued, the troublesome procedures must be repeated in each system.
CARDMAX “Enterprise One Card” will allow you to easily use systems such as: attendance management, consumption management, access control management, water control IC card shower management, IC card self-service laundry management and other systems; all management systems are based on the true “one card” “To design.
The “Enterprise One Card” system is designed for the many documents used in enterprises and the management is complicated. A card is used to replace the work card, library card, door opening key, food ticket, etc. currently used by the enterprise. Fundamentally Realize the vision of “one card in hand, travel all over the enterprise”. Through the enterprise’s enterprise network, computers in various places are gradually connected into a relatively large data network, so as to realize the unity and standardization of various data of the whole enterprise. It is an important symbol of the enterprise’s scientific and modern management.
The system adopts a star-shaped network structure, so a single machine swing or damage has no effect on the entire system; it completely solves the concurrent conflict problem caused by the simultaneous operation of multiple sites. The proximity card has a globally unique code. The communication between it and the reader is microwave communication. The microwave signal is intercepted by a special antenna and then decrypted to ensure the security of data and information.
The extended smart card has the following main functions:
A. Identity identification function: display identity and basic information, management of entry and exit of enterprises and offices;
B. Query function: query basic employee information, consumption information, access information, books, audio and video materials, etc.;
C. Rental function: equipment, books, audio and video materials can be rented;
D. Electronic wallet: storing cash, issuing bonuses, dining, medical treatment, copying, consumption, etc.;
E. Attendance management;
F. Vehicle entry and exit identification card;
G. Access control, automatic channel access control.
2.2 Design Basis and Principles of Enterprise All-in-One Card System
Implement a one-card management system, coordinate with other information infrastructure of the enterprise, and promote the improvement of enterprise information management level.
2.2.1 Reliability and stability: Reliability and stability should be fully considered in various aspects such as system equipment selection, network design, and software design. In terms of design, fault-tolerant design and development calculation structure should be adopted. In terms of equipment selection, the reliability of software and hardware must be ensured. Must consider adopting mature technology and products. Minimize the occurrence of failures in all aspects of equipment selection and system design.
2.2.2 Ease of management: The system administrator should have the ability to adjust the system without changing the operation of the system.
2.2.3 Maintainability: Maintainability is an important factor in the success of today’s application systems. It contains two meanings: easy troubleshooting of faults and simple daily management operations.
2.2.4 Advancement: In the case of investment expenses permitting, the latest modern technology and the most reliable results should be fully utilized, so that the system can adapt to social development in the longest possible time. From a long-term point of view, this is also the most cost-effective. Advancement is the desired goal of system construction. But the advanced nature faces many immature problems. Therefore, the system should be constructed as a system engineering, fully considering the present and the future. Focus on the present and the future, so that the system construction and business demand will grow simultaneously.
2.2.5 Integrity: The integrity of the system involves all aspects. For projects such as this system, these factors must be considered to form an organic smart card management system.
2.2.6 Applicability: When designing this system, first consider meeting the functional requirements and practical application needs of the smart card management system.
2.2.7 Openness: In order to ensure the coordinated operation of the products of various suppliers, while taking into account the long-term interests of investors, this system must be an open system and be implemented in conjunction with relevant international or industrial standards. It can be reasonably connected in multiple ways with the HR systems, ERP systems, and financial software systems of major domestic manufacturers.
2.2.8 Normative: Since this system is a comprehensive system, in the initial stage of system design and construction, various standards and specifications should be referred to, and various technical regulations of the specification should be followed, and standardized design and management of the system should be done. Work.
2.2.9 Scalability: This system considers the needs of future development, so it must be possible for the expansion and replacement of the system product series, capacity and processing capacity. This expansion not only fully protects the original investment, but also has a comparative advantage. High comprehensive performance-price ratio.
2.3 System characteristics
2.3.1 Adopt a multi-layer network structure: the system has flexible scalability, the lowest construction cost, and can effectively diversify risks. The developed system adopts a three-layer network structure, including an Ethernet network layer composed of a PC-based control terminal and a management terminal, a remote controller network layer based on a controller, and a card reader network layer. The future expansion of the system will increase the distance and nodes by adding Ethernet nodes (increasing the number of control terminals and management terminals), or even access to broadband networks; in a certain area, the expansion of the system can be achieved by adding controller nodes, and Only increase the lowest cost.
2.3.2 Reliable network protocol: At the Ethernet layer, the TCP/IP protocol is used between the control system software and the management system software, which has the characteristics of high fault tolerance, large information flow, and high speed. Whether it is a large system or a small system, in order to make the software universal, the network layer protocol must be able to satisfy both a single PC user and a network user composed of multiple PCs, management system software and control system software It can run on the same PC or run independently on multiple PCs.
2.3.3 Realization of multitasking and multithreading applications: Both the system’s controller software and control system terminal software must adopt multitasking and multithreading processing mechanisms. In addition to rapid response and processing of human-machine dialogue, the system software also requires high-speed response and To handle network communication tasks, but also need to monitor event ports and respond to and process events in real time. Because the access control terminal in the access control system not only needs to manage and control the controller network connected to it in real time, but also must respond to and process the requests and commands of the management terminal in real time. The access controller is connected between the card reader and the access control terminal. “Gateway”.
2.3.4 High reliability and stability: Because the main parts of the system equipment are designed and produced according to industrial control standards, the hardware circuit adopts industrial-grade electronic components, the PCB board adopts four-layer board surface-mounting technology, and many measures are taken to reduce the transmission power of alternating electromagnetic fields. Kind of anti-jamming measures. Therefore, the average trouble-free operation time of its equipment can be as high as 5000 hours. At the same time, the system equipment adopts relatively distributed control. In the event of a communication failure on the network, it can still continue to work in accordance with the preset working mode. Employees who have issued a card can use it as usual. During the failure, the employee’s card swiping records are temporarily stored in each lower-level computer. For reference. Once the fault is repaired, each network will automatically send the recorded data back to the system management center to ensure the integrity of the system information, and its safety and reliability will be greatly improved.
2.3.5 The system has ultra-large-scale data processing capabilities: the core equipment of the all-in-one card management system-access controllers, attendance machines, consumer machines, etc., all use Flash Jamp technology to achieve rapid query of large-capacity card data and read card recognition time Not more than 0.2 seconds. At the same time, the data storage capacity of the main controller can reach more than 4M. CARDMAX one-card management system database adopts standard MS SQL Sever large C/S multi-user database, provides Ole DB/ODBC universal access interface, G-level record volume, 10,000-level concurrent access, database performance is quite excellent, openness is good, and it can fully satisfy users The required ultra-large-scale data fast processing requirements.
2.3.6 Excellent database performance and good openness: The system database adopts standard MS SQL Sever large-scale C/S multi-user database, provides Ole DB/ODBC universal access interface, and provides import and export functions of Excel standard file format. This database can automatically extract card basic information from the card information database through the network, and convert it into its own one-card system operation database, and update it at any time according to user requirements, without the need for manual input of card information.
2.3.7 The system has good confidentiality performance: all data is stored in the data center database or local database. There is only the card serial number on the proximity card, and there is no employee personal information. Even if the employee card is lost, it will not cause any data. Lost. If the loss is reported in time, it will not have any impact on the system, and the system has good confidentiality performance.
All control boxes in the system adopt the key switch mode, and only authorized personnel can open and close all control boxes in the system for maintenance and to prevent malicious attacks.
The system software can provide multiple levels of password protection, manage and restrict different operators from using central monitoring, and prevent the system from being used by non-related personnel.
2.4 Mainly implemented system

Attendance management system: easily realize attendance management, generate reports, and perform accounting;
Consumption management system: electronic currency settlement can be carried out in canteens and other consumption places;
Patrol management system: Patrol personnel will patrol according to the designated route (using a card reader as a patrol point or using a handheld patrol machine) to strengthen overall safety. When an alarm occurs, the nearest alarm point can be used to give an alarm;
Water control management system: effective water control can save the company huge logistics costs;
System expansion: The IC card is highly expandable and can be expanded according to needs, such as laundry management, drinking water management, etc.
2.5 Access control system solution
2.5.1 System structure
The smart card access control management system is composed of a contactless smart card reader, an access controller, an electric control lock, an inductive smart card and management software. The composition diagram of the access control management system is as follows:
According to the feasibility of the system and the needs of users, the system structure model we can provide is the network wiring structure through the TCP/IP protocol. The TCP/IP access control system adopts a more advanced, more flexible, and more powerful internet/intranet network architecture, which provides users with a more complete choice.
2.5.2 TCP/IP network structure mode
TCP/IP mode, as the name implies, is to carry out data transmission and data conversion through the TCP/IP network protocol. In TCP/IP mode, the access controller can be directly connected to the internal LAN through a network switch, and the access control signal can be transmitted to the networked management computer through this switch. In this structure mode, the transmission distance is based on the computer network distance, and the number of access controller groups exchanged in the access network is not limited, which means that in this structure mode, the management computer can be controlled through the computer network Unlimited multiple controllers.
Generally speaking, compared to the access control system solution using the 485 bus structure, the TCP/IP access control management system has relatively large advantages in the following main aspects:
1) The data transmission speed is faster, and it makes full use of the bandwidth advantage of the TCP/IP network, which is essentially different from the serial communication of the 485 bus.
2) The TCP/IP protocol internally guarantees the correctness of data communication, avoiding possible problems during data transmission.
3) The system application is more flexible, and it can be directly applied to the local area network or even the wide area network.
4) The controller can actively communicate with the management system or database (via the communication center) to truly realize two-way real-time communication.
5) The user operation management interface is more friendly, and the installation and use are simpler and more convenient.
6) The TCP/IP access control management system is compatible with the 485 bus structure, and can adopt two communication methods: the TCP/IP protocol or the 485 bus.
When the TCP/IP network structure mode is adopted, it can be attached to the user’s original computer network to reduce the links of large-scale wiring. This structure mode is generally used in larger enterprises, most of which already have complete computer networks. Moreover, these enterprises have a large scope and a large number of door areas.
