At present, with the continuous development of the world economy and high technology. People are increasingly demanding the living environment. For the construction, in addition to the traditional requirements, people put forward higher requirements for safety, comfort, energy conservation, automation and information. Take architectural lighting as an example. At present, most buildings still use traditional switch control methods, and some intelligent buildings use building automation (BA) systems to monitor lighting. However, it can only implement simple area illumination and time switch functions, and cannot implement functions such as dimming control, scene control, and induction control.
1 Intelligent lighting
Intelligent lighting refers to the use of computer, wireless communication data transmission, spread spectrum power carrier communication technology, computer intelligent information processing and energy-saving electrical control technology to form a distributed wireless telemetry, remote control, remote signal control system to achieve lighting equipment Intelligent control. It has the functions of intensity adjustment, light soft start, timing control, scene setting, etc.; and achieves safety, energy saving, comfort and high efficiency.
At present, the technologies of intelligent lighting mainly include: power carrier technology; bus technology; wireless communication technology. The European InstallaTIon Bus (EIB) is a standard bus control system currently used in the field of intelligent buildings with the advantages of distribution, openness, reliability, security and flexibility. Now in the Chinese market, Siemens Instabus EIB and ABB have introduced i-busEIB two building intelligent control systems.
2 application examples
The following is a detailed description of the actual engineering case, i-busEIB building intelligent control system is applied in the intelligent lighting design of Shenzhen Exchange Square.
2.1 Project Overview
The building is located in Shenzhen, Guangdong Province. With a height of 245. 8 m and an area of ​​about 267,000 m2, it is a multi-purpose financial office building and is a super-class building. There are three floors underground, mainly garages, of which three underground floors are built-in civil air defense basements with two protection units. The above ground part is 46F, 16F and 32F are refuge layers. Among them, 15F or less is for the Shenzhen Stock Exchange; 17F to 43F are for renting office floors, and 44F to 46F are for clubs. Centralized control and management of all lighting systems in useful offices, east and south lobby, conference rooms, etc., to achieve automatic lighting control, energy saving, humanized operation, and improve property management.
Intelligent lighting control systems must meet the requirements of energy saving and green in terms of control, and adopt intelligent and integrated solutions to manage and create different working atmospheres while achieving energy saving.
Multi-functional integrated control: lighting control, glass partition shutter control, curtain control.
Various control methods: on-site intelligent panel, human body sensing (motion detection), light sensing (bright sensor), remote control, remote network control, timing control.
2.2 i-bus EIB system
The ABB i-bus system is an intelligent control system based on the EIB bus standard that controls the powerful end devices in a weak bus communication. The main functions are lighting control, curtain control, security, AV equipment and HVAC equipment control, etc., which can control various lights such as: switch control, dimming control, decentralized centralized control, remote control, delay control, timing control, Light sensing control, infrared remote control, mobile sensing control, linkage control with other equipment systems, etc., control mode is convenient, flexible, easy to modify, easy to operate, easy to maintain. With the continuous development of the world economy in high and new technology, people's requirements for the living environment are getting higher and higher. In addition to the traditional requirements for the building, higher requirements are imposed on the safety, comfort, energy saving, automation and informationization of the building. The purpose is to create a comfortable and pleasant environment, which can greatly improve the work efficiency and is extremely Flexible office and living environment.
2.3 Overall system composition
(1) The system structure adopts a distributed bus structure. Each intelligent module in the system can work independently without relying on other modules, and the modules should be peer-to-peer. When the management system host or server fails, the control module of the system is not affected, and it can still run independently according to the pre-programmed program.
(2) The system adopts a two-layer bus network topology. The management trunk uses the property measurement and control LAN, and the on-site lighting control bus uses the EIB bus. The EIB bus does not cross the floor.
(3) The system should be scalable. For the increase of functions or the increase of control loops and electrical appliances, it is only necessary to increase the hooking of the corresponding modules. The original hardware and wiring in the system can be achieved without changing.
2.4 Concrete implementation
According to the functional requirements of different rooms and the actual use after operation, the corresponding intelligent lighting control system strategy is as follows:
2.4.1 Way of using single light single control (to dim)
The main areas include: 9F office, senior management (11F ~ 15F) office, etc. Where single-lamp single control is required, the relevant luminaires use digital addressable lighting interface dimming ballasts (supporting DALI protocol). The control methods mainly include intelligent panel control, human body sensing control, and superior controller. Human body induction is mainly achieved by installing a mobile detection in the office. The relevant plane is shown in Figure 1.
