Integrated wiring and electrical safety of intelligent building

Introduction to smart buildings:

According to the definition of “Intelligent Building Design Standard” GB/T50314-2006: Taking buildings as a platform, taking into account information facility systems, information application systems, building equipment management systems, public safety systems, etc., it integrates structure, system, service, management and Its optimized combination is integrated to provide people with a safe, efficient, convenient, energy-saving, environmentally friendly and healthy building environment.


Intelligent System Integration (IIS): Intelligented Integration System

Information Infrastructure System (ITSI): Information Technology System Infrastructure

Information application system (ITAS): Information technology Application system

Building Management System (BMS): Building management system

Public Security System (PSS): Public security system

Information Technology System Infrastructure (ITSI: Information Technology System Infrastructure): In order to ensure the interconnection and smooth flow of information between buildings and external information communication networks, it receives, exchanges, transmits, stores, and retrieves various information such as voice, data, images, and multimedia. Combining various types of information equipment systems for comprehensive processing such as displays and displays, we provide an information and communication infrastructure that realizes application functions such as building business and management.

Information technology application system (ITAS: Information technology Application system): Based on the building information facility system and building equipment management system, it is a system that combines various information equipment and application software to meet various business and management functions of buildings. .

Building equipment management system (BMS: Building management system): a system that implements comprehensive management of building equipment monitoring systems and public safety systems.

Public security system (PSS: Public security system): In order to maintain public security and comprehensively use modern science and technology to deal with various emergencies that endanger social security, a technical prevention system or security system is constructed.

Intelligent Integration System (TIS: Intelligent Integration System): The building intelligent system with different functions is integrated through a unified information platform to form a system with comprehensive functions such as information collection, resource sharing and optimized management.

Building Equipment Management System (BMS):

The main functions of the building equipment management system:

It has the functions of measuring, monitoring and controlling building mechanical and electrical equipment;

It has the function of monitoring the environmental parameters of buildings;

To meet the property management needs of buildings, realize data sharing to generate various relevant information analysis and statistical reports required for energy saving and optimized management; data information and other resources related to public security and other related systems should be shared.

BMS adopts distributed control mode: centralized management, decentralized (on-site) control.

Fieldbus: Fieldbus is a serial digital data communication link, which communicates between basic control equipment in the field of process control and with automation control equipment in the field of higher-level automatic control.

Mainly include: LonWorks bus, BACnet bus.

On-site controller (Direct Digital Controller): It is a computer monitoring and control system that can operate independently.

Integrated wiring system:

The integrated wiring system is a transmission network between buildings or buildings, which enables voice, data communication equipment, information exchange equipment, building industry management and building automation management equipment and other systems inside buildings or buildings to communicate with each other. It can also connect the communication network equipment in the building with the external communication network.

The integrated wiring system is an independent system composed of transmission media (optical cables, twisted-pair cables) and related connection hardware (hubs, optical fiber transceivers, distribution frames, connectors, sockets, plugs, etc.).

The integrated wiring system can also be regarded as a combination of multiple subsystems in a modular structure.

The integrated wiring system is mainly used to transmit voice, data, image, multimedia services and other information in buildings (groups).

The structure of the integrated wiring system:

The integrated wiring system can be divided into 7 parts (or subsystems) from the structure: work area; wiring subsystem (horizontal subsystem); trunk subsystem (vertical subsystem); management; equipment room; building group subsystem; Incoming room.
