The proportion of intelligent buildings in construction projects is increasing year by year, but most of these construction projects are simple system integration projects with BA performance, which are not intelligent buildings at all. So, what is the difference between weak electricity engineering, system integration, and intelligent building?
　 First, weak electricity engineering
Compared with system integration and intelligent building, weak electricity engineering is already a relatively complete unit in construction engineering. With the continuous development of technology, weak electricity engineering can no longer be replaced in construction engineering.
For example, in the construction of residential buildings, subsystems of weak electricity engineering are gradually expanding. In addition to traditional cable TV and broadband networks, such as building access control, video surveillance, intrusion alarm, fiber-to-the-home, three-meter remote transmission, and property management are added. Wait for multiple subsystems.
The concept of green building and intelligent building is gradually gaining popularity, and it is gradually promoted in construction projects. The combination of household appliances integration and indoor information network switches and servers brings a more intelligent service experience. All functions need to be weak. Engineering support.
Most projects require weak current systems, but there is not much demand for system integration and smart buildings. When investing in the weak electricity part of the construction project, it is necessary to make investment considerations according to the actual conditions of the project.
Second, system integration
System integration is an important technical means to centrally control and control related equipment in the building (such as security, central air conditioning, water supply and drainage, fire protection, lighting, electromechanical and other professional subsystems).
It enables centralized control of each relatively independent operating system, including weak electronic systems and important operational projects within the building, as well as information sharing between individual buildings.
The centralized management system replaces the traditional management mode to realize the systematization and integration of management. Because the equipment, software and hardware involved in this process are numerous and not uniform, in order to achieve the purpose of unified deployment management, it is necessary to use certain technical means for resource integration, data processing, system compatibility, that is, system integration. It is much more complicated than a few weak electrical projects alone.
In addition to powerful control functions, the integrated software technology and supporting hardware configuration and information transmission and sharing between independent systems are important foundations for the normal operation of the integrated system.
Third, intelligent building
The intelligent building model needs to be realized based on system integration. It can integrate multiple related factors, multiple target optimizations, and multiple disciplines to achieve high sharing of all information resources. Thereby, the operating efficiency of all the equipment is greatly improved, the safe operation of the building is ensured, and the running cost can be reduced, and the comprehensive purpose of once and for all is realized.
Although intelligent buildings need to be based on system integration, it does not mean that intelligent buildings and systems can be equated. There is still a difference between the two. Because the application of intelligent buildings is very extensive, involving many aspects and comprehensive, it is necessary to deal with the preliminary work, especially the key links.
A systematic and comprehensive analysis should be carried out for each building's own functions and its management mode, and targeted research and demonstration should be carried out; through software analysis on the integration of special software management, software deepening research and development; through comprehensive analysis Complete and applicable software is applied to each subsystem for comprehensive integrated management.

Fumed Silica

Fumed Silica it is a kind of high purity white colloidal powder.Fumed Silica divide into Hydrophilic and hydrophobic different technologies products. Quanxu Technology Fumed Silica basically properties are white, non-toxic, tasteless, amorphous and inorganic. We have strictly control of particle size, surface area, and the products have more activate surface. With its unique features of particle size, high purity, aggregated structure and low bulk density, it is widely used in fine chemical such as Silicone Sealant, Rubber, Paints, Unsaturated Polyester, Cosmetics, Agriculture, and Medicine etc
