What are the components of an intelligent building system?

Intelligent building engineering includes communication network system, information network system, building equipment monitoring system, fire alarm and fire control linkage system, safety protection system, integrated wiring system, intelligent integrated system, power supply and grounding, environment and residential intelligent system, etc. 10 sub-division. So do you know what are the characteristics of intelligent building engineering? Besides high technology and intelligence, what else? Next, let's look at the details of Bian Xiao. Composition of intelligent building engineering

1, Building Equipment Automation System (BAS)

An integrated system is composed of air conditioning and ventilation, power distribution, lighting, water supply and drainage, heat source and heat exchange, chilled water, elevators and escalators in a building or building, with the purpose of centralized monitoring, control and management.

2. Communication network system

Communication network system is the infrastructure of voice, data and image transmission in buildings. Through the communication network system, it can be connected with external communication networks (such as public telephone network, integrated service digital network, Internet, data communication network, satellite communication network, etc.). ) ensure the smooth flow of information and realize information sharing.

3. Information network system

Information network system is an information network platform composed of computer technology, communication technology, multimedia technology, information security technology, behavioral science and other advanced technologies and equipment. With the help of this platform, information sharing, resource sharing, information transmission and processing are realized, and various application services are carried out on this basis.

4. Intelligent System Integration (ISI)

The integration of intelligent system should be based on sub-projects such as building equipment monitoring system, safety prevention system, automatic fire alarm and fire linkage system to realize the integration of building management system (BMS). BMS can be further integrated with information network system (INS) and communication network system (CNS) to realize intelligent building management integrated system (IBMS), so as to meet the requirements of building monitoring function, management function and information sharing. Through automatic detection and optimal control of buildings and building equipment, it can promote the optimal management of information resources, provide users with the best information service, and make intelligent buildings achieve the purpose of reasonable investment and meeting the needs of the information society.

5. Fire alarm system

It is composed of fire detection system, automatic fire alarm and fire fighting linkage system and automatic fire extinguishing system, which realizes automatic fire alarm and fire fighting linkage of buildings.

6. Safety System (SAS)

According to the needs of building safety management, for the purpose of maintaining public safety and preventing criminal crimes and disasters, a safety technical prevention system with alarm, video security monitoring, access control, safety inspection and parking lot (garage) management is formed by comprehensively using electronic information technology, computer network technology, video security monitoring technology and various modern safety prevention technologies.

7, residential (residential) intelligent (CI)

It is an intelligent system based on residential quarters, which has the functions of safety prevention system, automatic fire alarm and fire control linkage system, information network system, property management system and so on, and integrates these systems together. It has the functions of building system, service and management 8 and home controller (HC).

8. Home Controller (HC)

A controller or network system that completes all kinds of data collection, control, management and communication in the family should generally have the functions of home security, home fire protection, home appliance monitoring and information service.

9. Control network system

Through the control bus, the control equipment, sensors and actuators are connected together, and real-time information interaction is carried out to complete the network system of management and equipment monitoring.

Characteristics of intelligent building engineering

1, the important symbol of intelligent building is intelligent integrated system. It is the integration of various technologies and disciplines, involving electronic technology, communication technology, network technology, computer technology, automatic control technology, sensor technology and so on. The key to realize system integration is to solve the problem of interconnection between systems, which runs through the whole process of planning, design, construction and management of intelligent buildings. With the development of science and technology, there will be new technologies and systems to enrich and join this field.

2. There are many intelligent building engineering systems with high-tech characteristics, especially the intelligent engineering of large public buildings, which has long construction period, large working space and many kinds of equipment and materials. Generally, large engineering companies with strength and experience in intelligent system integration will complete all-round services from technology to construction design, product supply, installation and commissioning, acceptance and turnkey. Intelligent building engineering often starts from the foundation construction of building engineering and carries out construction cooperation. When the system enters the joint debugging stage, the construction project is often completed, the decoration and installation are finished, and sometimes even the construction project has been delivered. All systems of intelligent building engineering are still in the trial operation stage.

3. The engineering quality of intelligent system is complex, which consists of components quality, host equipment quality, terminal quality, system software quality and installation and debugging quality. And this requires close cooperation and mutual support in engineering design, building installation and equipment manufacturing. , and cannot be divided into segments. The quality of some intelligent building projects is not high, and the system opening rate is low. The main reason is not that the selected equipment is not good, but that the design, equipment manufacturing, installation and debugging, maintenance and technical services are divided into blocks, which causes many coordination difficulties. If the procurement of system equipment changes, the design will change accordingly, and the construction requirements will also change accordingly; If problems are found in the construction and design changes are needed, design changes should be made according to the actual situation. When the system equipment enters the debugging stage and integration stage, it is also inseparable from the equipment supplier and the integration software supplier, and the interfaces and protocols between various equipment and subsystems must be solved.

4. Intelligent building projects should pay special attention to close cooperation with other projects, such as civil engineering, equipment, pipelines, electricity, lighting, air conditioning, etc. Because it is closely related to the nature, function and scale of the building, the distribution of information points is also different, so we should fully consider the site conditions of the building, coordinate reasonably and solve the coordination problem of pipeline laying, especially with the construction of decoration projects.

5. Generally, the completion acceptance of intelligent building projects is carried out separately by systems, and some systems have to be put into normal operation for a long time (1 ~ 3 months). According to the Code for Quality Acceptance of Intelligent Building Projects (GB503392003) and the current national standards of each system, such as the Code for Construction and Acceptance of Automatic Fire Alarm Systems (GB 5016622)
