It is a comprehensive office building; another building is built separately next to it There is a lecture hall with two floors and a building area of 1,650 square meters.
Design Principles:
The office building is constructed in accordance with the goals and requirements of the intelligent building, combining complete service facilities, advanced electromechanical equipment, modern office and communication systems, and intelligent management and control modes.
Give full play to the use functions of the main equipment in the building, integrate power supply, air-conditioning facilities, fire alarm, comprehensive security, access control system, etc. into a comprehensive unified system, and implement hierarchical distributed control, centralized monitoring and unified management.
With efficient and fast information communication processing function, it can detect and receive the content of major programs in the world at any time, and publish and exchange information, providing comprehensive and three-dimensional advanced communication methods and services.
Make full use of modern advanced technology and methods to create a safe, reliable, comfortable and efficient working and living environment inside the building, and provide an optimized place for work, life, entertainment and leisure.
The structured integrated wiring system adopts plastic optical fiber wiring in the building and complies with various design and installation standards. It provides an advanced, unified and reliable data, voice and video transmission platform to fully meet the needs of office automation and communication automation, and adapt to the future 10 The need for technological upgrading and application development during the year.
The system also has the functions of Internet, IPTV, and VoIP.
Using the GEPON+ plastic optical fiber LAN solution, data, voice, and TV are integrated into one network system to achieve “three networks in one.”
The entire integrated wiring system will fully embody the principles of advanced, practical, reliable, economical, open, expanded and modular, standardized and easy to maintain.
Overall design:
The following is a diagram of the system structure. The structure diagram is divided into three parts:
The first part is the central computer room. This part is the collection end of user terminal data. The main equipment placed is the core switch, server group, monitoring center and the core equipment OLT of the GEPON system. The main function of this part is to provide terminal users in the building. The data is collected and connected to the external network. Among them, the data part of the business is realized by connecting to the Internet through the core switch; the traditional analog voice part of the business is realized by connecting to the PSTN network through the voice relay gateway.
The second part is the floor part, where access equipment such as ONU and plastic optical fiber switches are mainly placed.
The third part is the office area, which is mainly used to realize the network connection of a variety of user terminal equipment (computers, telephones, IPTV, etc.). All user terminal signals are converted into data signals and gathered to the central computer room through GEPON equipment to finally achieve network integration .

In terms of the front-end camera placement, full careful consideration is made to enable the system to capture the target in the shortest time, so that the security personnel can grasp the situation on the spot in time, and detect and avoid sudden and vicious incidents. The specific design is as follows:
The underground garage is equipped with 12 dome cameras, 7 elevator car dome cameras, 4 dome cameras in the exhibition hall, 12 dome cameras in the restaurant, 24 dome cameras in the elevator halls of each floor, 56 dome cameras in the entrance and exit of each floor, and entrances and exits of the garage. A total of 2 wide-dynamic cameras are set up, 6 high-speed domes are set up on the perimeter of the building, a total of about 123 monitoring points are set up, matrix + hard disk video recorder system architecture, UPS integrated power supply. Set up an anti-theft alarm system, set up infrared detectors on the first floor of the building, set up double-check alarm detectors in important rooms, set up manual alarm buttons in the financial room and leadership rooms, set up door magnetic alarms, etc., which are linked with the monitoring system.
One card subsystem:
As a modern office building, all-in-one card management has become one of the indispensable weak current systems. Among them, garage access management, access control systems and consumer systems are widely used in modern buildings. According to the actual needs of the building, we set up all-in-one card points in key office areas and garages:

Note: The all-in-one card network uses plastic optical fiber wiring and connects to the plastic optical fiber switch.
We use the attendance management subsystem, access control management subsystem, consumption management subsystem, intelligent parking subsystem, and parking guidance subsystem in the one-card system in the office building of the group. In addition, the one-card system can also support elevator control, intelligent channel control, conference sign-in and other applications.
Access control subsystem:
The system adopts the internationally popular non-contact IC card access control system, which has high security, convenience and cost-effectiveness, is not easy to be copied, has a record of opening the door, and can monitor each door in real time and link with the security system. Compared with the traditional contact IC card, it has the advantages of high reliability and long life. The access control system is transmitted by plastic optical fiber through the TCP/IP Ethernet communication protocol, connected to the back-end plastic optical fiber switch, and communicates with the management center. In order to carry out data analysis, statistical reports, and attendance management.
