  In recent years,With the rapid development of real estate industry in our country,Intelligent building industry development is very rapid,All kinds of high-grade residential area, the government office buildings, commercial buildings, hotels, public buildings and intelligent application of intelligent household is becoming more and more widely,The requirement of intelligent functions tend to be more diversified and comprehensive.

  At the same time,The intelligent system is a project of system integration is higher,It is very strong demands on technology integration and compatibility,Areas a lot,From electrical, electronic, computer, automation to hvac, systems integration and other aspects of content.One of the intelligent lighting system is applied more widely,Also is very easily confused with building automation system in the practical operation of one of the subsystems.

  In the existing lighting system design of the intelligent building,General still use the old design method,Or in the lighting design system of the past simply by series in the lighting circuit controlled by the building automation system (BAS) contact, increase the central monitoring function to realize the special control or regional control and timer switch,As well as increasing infrared induction to achieve shape control.Of course,This control method has its obvious limitations:

  Economy:Investors to save costs,The design of the electric circuits of the small number,

Tend to notice when designing control over a large area,If from the perspective of humanity, energy-saving electric circuits of the segmentation,Can cause a large increase in investment costs,This is what investors are reluctant to see.But the loop, in turn, significantly increase the use of ultimate owner costs (electricity).

  Convenience:Due to this kind of design are not usually set the switch at the scene,And all the lighting circuit is controlled by BAS for centralized control,The user can't which can switch and adjust according to the actual situation,Can't state intervention lighting and illumination,For practical use is very inconvenience.At the same time,As a result of the control function is too simple,The traditional lighting design in building automation system (BAS) can only implement simple time switch function,If you want to achieve certain areas of the scene default, scene transformation and brightness adjustment,Actual operation of the technical difficulty is considerable.

  Independence:Because this kind of simple sum up of the lighting system is not a truly independent subsystem,In the building automation system (BAS) failure,Lighting system will also be affected,Especially for lighting circuits have emergency evacuation lighting function,This is absolutely can't forgive.

  Intelligent lighting system (EIB),Is dedicated to lighting needs and development of an intelligent system,It not only can run independently,But also can realize the existing traditional lighting design in intelligent building cannot achieve the effect.Such as Siemens (Instabus EIB), ash brown will ferrell (ABB) of the company's intelligent lighting system etc,It has a set of independent control protocol,And relative to the BAS system control is more simple,At the same time also can meet the needs of general construction for lighting control.

  Intelligent lighting system based on the system bus,Its open protocol,Flexible connection mode,Well guarantee the openness of the system.Its main functions and characteristics are as follows:

  Simple design is more economical.The lighting circuit design is simple,System installation and convenient,Operation and maintenance easy,The programmability of software and hardware of the flexible structure,Save building developers investment cost and operation cost,Shorten installation period,Improve the return on investment.

  System to the input, output, and system support units can be through the intelligent lighting system controller,Large section load cable from the output of the output unit directly to the lighting or other electricity load without through the switch,Don't have to consider when installing any control relationship,Again through the software set in the system after the installation address coding of each unit,To establish the corresponding control.Installation time simply by using load cable connection between the output unit and load,Can save a lot of cables,Also shorten the construction time and labor cost.

  Intelligent control cost savings.Intelligent lighting system with control software for the whole lighting system for remote control and central control,May at any time, easily according to user needs to modify control relations.When some reason need change lighting control relationship,By changes in software,Without the cable laying.

   At the same time with infrared ray sensor, brightness sensor, timer switch, and the mode of the adjustable optical technology and intelligent,Any single point, two point, multipoint, regions, groups, logic control,Time switch, brightness hands/automatic adjustment, infrared monitoring, remote control, scene combination and various lighting control function,Not only can show rich lighting effects,The entire lighting system can work accurately in accordance with the best economical solution,So as to greatly reduce the cost of operation and management,Maximize energy savings.And compared with the traditional way of lighting control,Can also save energy,Reduce the use cost,So as to realize social cost savings.

  More system compatibility and diversity.Because the system of each input/output unit is stored in the system state and control instruction,Don't lose data after blackout,When to restore power,System parameters according to the preset memory,Automatic recovery power before working condition,Realize the unattended.

  At the same time,Control circuit and load circuit separation,Input and output unit with only one line of two core as connected to the bus,You can add a new control unit in the network at any time.And the design of the distributed intelligent control and open system,

Through communication protocol (OPC) ways to make it with other building management system (BMS), building automation system (BAS), security and fire control system combined well,

To improve the level of intelligent property management,Conform to the trend of the development of modern life.

  The system administrator as long as according to user requirements and the change of external environment,Just modify the software Settings,Or a few lines,You can adjust the lighting layout and extend the functionality,Suitable for commercial, industrial and household use different requirements.The BAS system building,If the consideration together in the design of intelligent lighting system for the building,Will promote the intelligent building.
