1 Introduction
In the past, due to cost, immature technology and other reasons, the intelligent lighting system was only applied in some key projects and venues, stage and other occasions that required specific lighting scenes. With the intelligentization of buildings becoming the mainstream technology of today's building development, the localization of various intelligent lighting devices and modules is getting higher and higher, and the products are becoming more and more abundant. The intelligent lighting control system has also gained a certain scale in the office building. application. The lighting system in the office building must not only have sufficient illumination, but also meet the comfortable visual experience in the building, reducing light interference and pollution. The introduction of intelligent lighting control systems is the ideal solution to meet these requirements.
2 Structure and application of intelligent lighting system
Kunming Post Complex is a 21-storey comprehensive office building with an i-bus intelligent installation system that controls lighting including underground garages, 1 to 21 storey office buildings, conference rooms, public corridors, water heaters and UPS lighting systems. Management of electrical loads. The lighting of the whole building can be adjusted according to the set time and external light conditions, or can be controlled by the central control room; the power load of the water heater can be controlled according to time or centralized; all lighting control and heaters can be used The central control room conducts operation, monitoring and fault recording to make the power load management of the office building intelligent.
(1) Energy saving in underground garage
The use of 12 motion sensors effectively reduces the energy used in underground garage lighting. In order to achieve full coverage, we set the motion sensor at each entrance and the necessary corners. Once the sensor is triggered by the moving vehicle, the corresponding area illumination is immediately turned on and turned off after 5 minutes to save energy.
(2) Scene lighting control from 1st to 3rd floors
The system uses a Busch-tritor switch, all of which can be operated with one button and can be set up to 10 different scenes. The 16 sets of lights in the room can be controlled independently, each set of lamps can reach 3000W; the other 12 sets of lamps can be dimmed, and each set of lamps does not exceed 1000W. All functions are available via an infrared handheld controller.
(3) Security function when the ground glass breaks
There are 60 glass break sensors on the ground around the building. Any action that breaks the glass will activate the area terminal and issue a command to the dual-value output control external light and camera to record the person who crushed the glass in time. The alarm signal also appears on the display of the monitoring room.
(4) 4-layer conference scene light control
The system uses a Busch-triton switch, and all lights and curtains can be controlled by one button and up to 4 different scenes can be set. The four sets of lights in the hall can be independently controlled, and the power of each set of lamps can reach 3000W; the other two sets of lamps can be dimmed, and the power of each set of lamps does not exceed 500W. The electric curtains around all rooms are controlled by 2 separate sets of switches, all of which are implemented by infrared hand-held sensors. A mobile sensor is installed near the doorway. The preset light automatically turns on when someone enters the room, and the time goes out after the person leaves, making the security check easier to operate and save energy.
(5) Power control and monitoring from 7 to 20 layers
The Win-Switch of the central control room controls the dual-value output of each layer via a twisted pair and thus controls all public lights, office lights, water heaters and UPS. After converting the signal through the current sensor and current regulator, Win-Switch can display the percentage of load current of each layer. The Win-Switch also has indication and alarm functions and can control each loop with time. When the load is overloaded, the system will alarm and will automatically cut off all power to the layer after receiving the indication signal from the smoke detector.
(6) Scene control of a 21-story multi-function room
The system uses a Busch-triton switch, and all lights and curtains can be operated with one button, allowing up to 10 different scenes to be set. The four sets of lights in the room can be controlled independently, each set of lamps can reach 3000W; the other 6 sets of lamps can be dimmed, each set of lamps does not exceed 1000W, and there are 6 sets that can be applied. The electric curtains around all halls are controlled by two separate sets of switches. All functions are available via an infrared handheld controller. Install two motion sensors near the door. The preset lights will turn on when someone enters the room, and then turn off when they go out.
3 Intelligent lighting control system application effect
(1) Reduce investment, reduce energy consumption, and extend life
Energy saving is the biggest advantage of intelligent lighting control systems. According to foreign statistics, office lighting uses about one-third of the energy consumption of the entire office building, and office lighting equipment costs about one-tenth of the electrical engineering costs. Therefore, choosing a reasonable lighting plan not only saves energy. It can also reduce the workload of pipe wiring construction. The traditional lighting mode of public buildings can only be turned off during the day and turned on at night. After adopting the intelligent lighting control system, the manager can divide the time period and working mode according to different occasions and different people's traffic, so that unnecessary lighting is automatically turned off, and the necessary lighting is automatically turned on when needed, effectively reducing The working hours of the lamps save unnecessary energy consumption and extend the life of the lamps. At the same time, the system can also make full use of natural light, and automatically adjust the indoor illumination through electric curtains and dimming modules.
(2) A variety of lighting scenarios
A variety of lighting control solutions can make the same building have a variety of artistic effects, adding a lot to the building. In a building, outdoor landscape lighting and floodlighting can be preset to seasonal changes in spring, summer, autumn and winter, weekend holiday scenes, large-scale celebration scenes, etc.; meeting rooms, conference rooms, etc. can be preset for meetings, projections, breaks, etc. Scenes. In the traditional manual control mode, it is difficult to achieve such a variety of lighting effects.
(3) Improve management level
The intelligent lighting control system is based on automatic control and supplemented by manual control. Under normal circumstances, the lighting system can automatically realize the switching and dimming functions without involving anyone, which reduces the number of managers and eliminates the human factors.
4 Conclusion
The intelligent lighting control system saves electricity and management expenses while saving energy and saving the use of lamps. According to the operation of the office building, the energy saving effect can reach 20% to 50%; the energy saving effect of general shopping malls, hotels, subway stations and other places can reach 25% to 30%, and the service life of the lamps can be extended by 2~ 3 times. Although the initial investment is slightly larger, construction wiring is reduced, control equipment is saved, and energy consumption is reduced. According to statistics, the average user can recover the investment within 2 to 3 years only in terms of energy saving and equipment wiring reduction, and the effect is satisfactory.
