Project Introduction
China International Center, the new landmark of Guangzhou skyscraper, is the second phase of China Plaza developed by Guangzhou Xingsheng Real Estate Development Co., Ltd. It is an international A-level office building. The south tower has 27 floors and the total height is 128m; the north tower is 62 floors and the total height is 268m. It is the second tallest office building in Guangzhou. With its high-end quality, China International Center was awarded the “Top Ten Most Valuable Office Buildings in China” in 2005-2006, and became the “Headquarters Economic Development Base” listed by the Yuexiu District Government.
In terms of the development concept, the developer boldly introduced the concept of “TOFO International Class A Office Building” and perfectly integrated the two product functions of “TOPOFFICE” with an international Class A business space and “FITOFFICE”, an office space with 24 hours residence.
The hardware configuration is far ahead of similar Grade A office buildings in the market, such as the first in China to adopt a gigabit EPON network, the first in Guangzhou to report the time on time on the building body, the first to adopt an access control security system in Guangzhou, and so on. The CEO residence of China International Center only has 10 seats, and the CEO residence of China International Center in Guangzhou starts at 50,000 yuan/square meter.
system requirement
Zhonghua Plaza uses 28 imported Mitsubishi high-speed group-controlled elevators, of which 25 elevators are equipped with “Intelligent Dragon” brand IC card elevator control systems. Because developers have high requirements for the safety management of office buildings, they have to implement it for 24 hours. Supervision, so some elevators adopt the intercom linkage elevator control system. Shenzhen Wanglong Company connects the IC card elevator control system and the visual intercom two independent systems, and finally realizes the IC card elevator intercom linkage function. Solve the problem of difficult visits by guests.
System Features
• The IC card elevator system of Guangzhou Zhonghua Plaza adopts a networked management mode with RS485 interface. It uploads and downloads data through the network or data collector and the elevator management computer, and feeds back the credit card record to the management center in real time.
•The IC card elevator controller and the elevator itself are connected by passive contacts, and the two are completely isolated to ensure that the two operations do not interfere with each other.
• Time period limitation: flexibly set the time period of card swiping (ie IC card control period) and non-swiping period of use (ie open use period), which can be customized for building, elevator number, and elevator floor. Both functions are over. It will be automatically converted after a period of time.
• Direct card swiping: direct registration by swiping the card, no buttons required, showing intelligence, users with only one floor authority in the card can realize the direct swiping function.
•Password keyboard: For owners who forgot to bring their card, a function of using the elevator according to the password keyboard is added. Each floor corresponds to a different password. Each floor can be set by the owner according to the needs of different passwords. The password setting is consistent with The modification is done by the owner himself, no need to go through the property management office. The user only needs to remember the password of the corresponding floor and enter it, and the floor button will be automatically activated.
• Realize the linkage function with the intercom system: the owner can open the elevator for visitors through the intercom system at home.
Design Principles
In accordance with China Plaza’s bidding requirements for IC card elevator control system design, we take “advanced, practical and safe” as the guiding ideology of system design.
Advancement: The construction of the system is based on today’s internationally advanced and promising technologies that represent mainstream trends. The system thus achieved can be continuously upgraded with the development of information technology in the future. For example, the server uses Microsoft’s Win2000/NT operating system, the workstation computer uses the Win2000 operating system, the database uses Microsoft’s Microsoft SQL Server 2000, and the front-end applications are developed using the most advanced Delphi at present.
Practicability: The system fully understands and analyzes the user’s various management modes and characteristics. The development of each application system should be fully functional, easy to use, scientific and technological, and economical, reasonable, practical, and efficient. At the same time, targeted designs and flexible solutions can be made for specific needs and actual conditions of on-site engineering.
Security: The design of the system is highly reliable, and the product has mature and stable performance to ensure long-term trouble-free operation of the system. Even if an accident causes an interruption, the accuracy, integrity and consistency of the data can be ensured, and it can quickly return to normal. . The system strictly controls the operation authority of the administrator, and can adopt the installation of firewall, installation of anti-virus software, network database backup, etc. to ensure the safety and normal operation of the database server and each workstation. The authority of reporting lost cards and blacklisted cards can be cancelled in real time, preventing fraudulent use and abuse, and ensuring the security of the entire system.
Extensibility: Adopting plug-in expansion method, not only can meet the needs of current users in terms of capacity and functions, but also can be easily expanded due to the standardization and open compatibility of the system to ensure that users can expand and upgrade in the future. The system can increase the current capacity at will. There are systematic control equipment, and new subsystems can be added one by one to form a larger all-in-one card system.
System usage mode
For office buildings: The owner uses the elevator to operate the IC card to directly reach the floor where the owner is located. If the owner forgets to bring his card, he can enter the designated floor by entering the designated floor number and password on the card reader keyboard.
For property management: a card that can go to all floors or some floors can be configured. After entering the elevator and swiping the card, press the key of a certain floor.
For visitors: The visitor connects to the extension through the building intercom, and the owner unlocks the visitor; at the same time, a signal is given to the elevator to start the elevator down to the first floor; after the visitor enters the elevator, press the floor key of the owner to go directly to the floor.
Owner’s drop-in: The owner’s drop-in can be realized by the way the owner provides a password, and at the same time, the administrator can use the reception card to open the access authority of the designated floor.
Underground parking lot: For non-owner personnel, it can be set up so that they can only reach the ground floor and cannot enter the owner’s floor and underground parking lot.
Top-level sightseeing: For non-owner personnel, it can be set up so that they can only reach the sightseeing floor and cannot enter the floor where the owner is located.
Special situation: Since the IC card system can realize the linkage with the fire signal, after the fire signal is activated, the elevator is automatically not controlled by the IC card to ensure the emergency use of the elevator in emergency situations.
How to use IC card elevator visitor: When the guest comes to visit, first use the intercom system to call the resident, the resident agrees to the guest to come in, opens the unit door, and also sends a signal to the IC card control system that the guest can reach the floor. When the elevator reaches the bottom floor, After entering the elevator, guests can press the authority button according to the owner’s authorization to reach the designated floor. For other unauthorized floors, visitors cannot register by pressing keys. At the same time, it effectively solves the problem of elevator group control. Ensure the safety and reliability of the community and the building. The specific use process is shown in the attached picture:
This function has been applied to many high-end luxury houses, such as Shenzhen Xiangmihu No. 1, Shenzhen Overseas Chinese Town Oriental Garden, Zhuhai Yunshan Poetic Garden, Foshan Poly Mansion No. 1 Qiandeng Lake, etc.
Concluding remarks
Shenzhen Wanglong Company has always adhered to the principle of “user-oriented”, using its own IC card elevator control system invention patent technology, combining the precipitation of IC card technology researched for many years, and responding to the video intercom technology and market demand Carried out detailed and sufficient research, and proposed a complete and safe solution for Xingsheng Real Estate Company. Upgrade the functions of the original IC card elevator control system of the China International Center, and cooperate with Party A to integrate the all-in-one card system to achieve the purpose of the all-in-one card of the China International Center.
