As a mature IC card system integrator in China, Huaxu Gold Card Co., Ltd. integrates its self-designed and developed software system and hardware system in the smart building card project, and realizes it on the same system platform with an IC card Complete system-wide identification, attendance management, consumption, data lending, entrance and exit control, security patrols, parking lot management and other tasks for the media. The terminal devices in the system will recognize the card in a timely, accurate and correct manner, or accept management instructions, or enjoy consumer services, so as to truly realize a card in hand and a smooth global situation.
From a technical point of view, a single IC card is used to realize multiple function management. The card has independent channels and different corresponding application partitions. These partitions can be encrypted and password verified to ensure the independence of each partition. And safety; from a business perspective, its purpose is to make the building safe, efficient, comfortable, convenient and flexible.
1 Project overview
The Huaxu Gold Card Intelligent Building System will provide the “One Card” function for the integrated management and service of the China Telecom Group’s Telecom Command Center Building, including: identity management, attendance management, consumption management (canteen, entertainment, fitness and medical care), Information borrowing, entrance and exit control management, security patrol management, parking lot management.
The Telecommunications Command Center Building of the General Administration of China Telecom is located in C5 Plot, Financial Street, Xicheng District, Beijing. It has a total construction area of 58,398 square meters, 19 floors above ground and 3 floors underground. It was put into use in 2000.
2 Scheme design
2.1 System integration goals
On the operating platform of the smart card system, it will be integrated with security systems, property management systems, office automation systems, library management systems, medical management systems, and internal consumption systems to form a comprehensive service management system for the building’s “one card”.
2.2 Key technologies and solutions
The China Telecom Group Smart Card System essentially means that the cardholder can use one card to have unimpeded access in all related areas of the entire system, and various terminal devices can recognize this card, so as to achieve the purpose of the all-in-one card.
Through the unified issuance of cards, unified database management to achieve “all-in-one card”. When the card is issued, the data required by each subsystem such as identification information, amount information, transaction information, etc. are recorded on the card. The central database records various information tables such as transaction flow reservoir tables, terminal equipment management database tables, card database tables, cardholder database tables, and unit database tables. Each subsystem shares the card and database, extracts the required information from the card or database according to their specific needs, and can write the results into the database or card when necessary, so as to realize the information sharing of the entire system. Figure 1 is the overall design logic diagram of the system, which mainly shows the composition and data flow of the system.
3 System composition
3.1 Network system
The entire network can be seen as three major structures, namely, the management LAN of each subsystem, the backbone network of the building and the LAN of the control center. The management and control LAN of each subsystem that composes the whole building one-card system network. The central LAN can be divided into the following subnets: access control, attendance, patrol management subnet, library management subnet, property management subnet, consumer subnet, Parking lot management subnet, medical management subnet, control center local area network.
3.2 Application software system
Including the host server, the client workstation in the center and the information query workstation in the lobby. Specifically, it consists of a card issuing subsystem, an information management subsystem, a real-time monitoring subsystem, a statistics and analysis subsystem, an information service subsystem, an accounting management subsystem, a clearing subsystem, a reporting subsystem, and a security management subsystem. .
The control center of the all-in-one card system is composed of the application software system and its hardware system. This center is both a management center, a card issuance center, and a clearing center.
4 Project advantages
The smart card system designed by Huaxu Gold Card Co., Ltd. has been successfully applied to the management and services of many smart building projects. This system integrates equipment, system software, application software, and organizational structure based on the principles of safety and stability, and system integration technology based on world-class equipment and advanced IC card design concepts. Process design, database design, network construction, etc., can meet the needs of both management and consumption of the system. This plan combines advanced equipment with scientific management, changes the traditional management mode, and enhances the effectiveness of internal links, thereby improving customer service levels and truly achieving the goal of the smart building all-in-one card.
