Advantages of HDL-BUS Smart Environment Art Lighting System in Intelligent Buildings

Abstract: This paper compares the HDL-BUS smart environment art lighting system with the traditional lighting system, and explains the difference between the intelligent lighting system and the traditional lighting system from the aspects of control, laying, management and energy saving. The current application scope and development prospects of intelligent lighting systems and related problems in the application of intelligent buildings are discussed.

I. Overview <br> Since the 1990s, intelligent buildings have become the mainstream technology for today's building development, ranging from air conditioning systems, fire protection systems to security systems and sophisticated computer networks and communication systems. However, for a long time, intelligent lighting has been neglected in China. (especially the Chinese national enterprise brand, in many project tenders, it is stipulated that the import can only be tendered, which seriously undermined the self-confidence of national brands and affected the national brands to some extent. Increased visibility.). Most buildings still use traditional lighting control methods. Some smart buildings use building automation (BA) systems to control lighting, but only simple area lighting and time Switch functions are available. In contrast, intelligent lighting systems are being accepted by more and more people due to their superiority, convenience, flexibility, energy conservation, etc., and are increasingly used in intelligent buildings.

Second, HDL-BUS Shiqi intelligent environment art lighting system advantages in intelligent building 1, lighting control intelligent: using HDL-BUS Shiqi intelligent environment art lighting system, so that the lighting system works in a fully automated state, the system will Switch according to the preset lighting scene status. E.g:
1 From the perspective of energy saving, the system will automatically enter the morning work state half an hour before going to work in the morning, turn on some public area lights, and turn on the public lights of most public areas and some office areas 15 minutes before going to work in the morning. Open the public area lights, public lights in the office area during business hours.
2 At noon lunch time, the system will automatically enter the lunch break state, turn off some public area lights, and open the public light of 1/3 office area.
15 minutes after work in the afternoon, the system will automatically enter the working state at night, automatically and extremely slowly dim the lights in each area, and the system's motion detection function will automatically take effect, automatically turn off the lights in the unmanned area, and will The light in some areas is adjusted to the most appropriate brightness. These states are automatically converted to each other at a preset time.
In addition, the illuminance of each area can be changed through the on-site control panel to suit different scene requirements in various occasions. Intelligent lighting can automatically adjust the illuminance to the most appropriate level of work during the strong natural light period from 11 am to 4 pm. For example, in places with good natural light, such as near windows, the system will make good use of natural light lighting to adjust to the most appropriate level. When the weather changes, the system can still automatically adjust the illuminance to the most appropriate level. In short, the system ensures that the indoor illumination is maintained at a predetermined level no matter where it is or how the weather changes.

2. Improve the working environment and improve work efficiency. In the office of the building, the HDL-BUS intelligent environmental art lighting system uses advanced power electronics technology. Fluorescent lamps with dimmable electronic rectifiers are significantly superior to fluorescent lamps of traditional lighting systems: they are equipped with traditional ballasts. The fluorescent lamp flashes at a frequency of 100 Hz (twice the frequency of the grid). This strobe causes the staff to feel dizzy and eye fatigue, reducing work efficiency. The dimmable electronic ballast operates at high frequencies (40 to 70 kHz), which not only overcomes the stroboscopic, but also eliminates the instability of the brightness of the starter lamp due to the use of the starter. The office environment has been improved, and while providing a healthy and comfortable environment for people, it has also improved work efficiency.

3, considerable energy saving effect. 1 Use the time timer to run automatically on time. 2 Using advanced power electronics technology, intelligent dimming of most luminaire sources (including incandescent lamps, fluorescent lamps, sodium lamps with special ballasts, mercury lamps, neon lights, etc.). When the outdoor light is strong, the indoor illumination is automatically dimmed, and when the outdoor light is weak, the indoor illumination is automatically brightened, so that the indoor illumination is always kept at a constant value, so that the natural light can be fully utilized to achieve energy saving. In addition, the intelligent lighting management system adopts the method of setting the lighting working state and realizes energy saving through intelligent management.

4. Improve management and reduce maintenance costs. The intelligent lighting control system transforms the general lighting artificial opening and closing into intelligent management, which not only enables the building managers to apply their high-quality management awareness to the lighting control system, but also greatly reduces the operation and maintenance costs of the building. And bring great return on investment.

Third, HDL-BUS Shiqi intelligent environment art lighting control system and traditional lighting system comparison

1. Traditional lighting control system:
1 The control switch is directly connected to the load circuit. When the load is large, the capacity of the control switch should be increased accordingly. When implementing dual control, two single-pole and double-switches are used, and the lighting cable is connected between the switches; when the switch is far from the load At this time, the amount of large-section cable is increased; only a simple switching function can be realized.
2 When the multi-point control is performed, the cable connection between the switches increases, which makes the wiring installation very complicated and the construction difficulty becomes more difficult.
3 The traditional control adopts the manual switch, which must be turned on or off all the way, and the control mode is single.

2, HDL-BUS Shiqi intelligent environment art lighting system control system:
1 The load circuit is connected to the output of the output unit, and the control switch is connected to the output unit with an RS-485 bus. When the load capacity is large, only consider increasing the capacity of the output unit, and the control switch is not affected; when implementing dual control, it is only necessary to connect a switch in parallel on the control bus; when performing multi-point control, multiple switches are connected in parallel, and the switch is Only one bus connection is used, and the line installation is simple and saves trouble.
2 When the switch distance is long, it only needs to lengthen the length of the RS-485 bus to save the large-section cable consumption;
3 Various functions (on/off, dimming, timing, etc.) can be set by software. The intelligent lighting control adopts low-voltage (24V) signal control, with strong control function, multiple modes, wide range and high degree of automation. By implementing the preset and memory functions of the scene, you only need to press one of the keys on the control panel to start. A lighting scene (different light and dark of each lighting circuit to form a lighting effect), each lighting circuit will automatically change to the corresponding state. Create different lighting effects and a comfortable atmosphere. The above functions can also be implemented by other interfaces such as a remote controller.
4 Intelligent control system can realize energy management automation. Through a distributed network, the entire building can be managed with just one computer.

Fourth, the advantages of HDL-BUS Shiqi intelligent environment art lighting system

　　 1. Centralized management and reduction of man-made waste In modern high-rise buildings, the phenomenon of artificially wasting lighting energy is still very serious. No matter whether there are people in rooms, walkways or toilets, there are still people who are often “changing lanterns”. HDL-BUS Smart Environment Art Lighting System can be decentralized and centrally managed. In the central control room of the building, managers can turn off the lights in unmanned rooms by operating the keyboard. In addition to monitoring the lighting in the central control room, the management personnel use the mobile phone to directly control the light through short messages after inputting the correct password.

2, automatic dimming, make full use of natural light, maintain the consistency of illumination HDL-BUS Shiqi intelligent environment art lighting system brightness sensor by measuring the illuminance of the working surface, compared with the set working illuminance value to control lighting Illumination to the ideal working environment, which maximizes the use of natural light for energy saving purposes and provides a relatively stable visual environment that is unaffected by seasonal and external climates. Generally speaking, the closer to the window, the higher the natural illumination, so that the illumination provided by artificial illumination can be low, but the synthetic illumination should be maintained at the design illumination value to maintain the uniformity of illumination.

3, easy to install, save cable HDL-BUS Shiqi intelligent environment art lighting system, use RS-485 bus to input each input (intelligent panel), output unit (intelligent control module) and system components (bus converter) Connected, the large-section load cable is directly connected to the lighting fixture or other electrical load from the output of the output unit without going through the smart panel. It is not necessary to consider any control relationship during installation. After the entire system is installed, the address code of each unit is set by software to establish a corresponding control relationship. Since the system only uses the load cable connection between the output unit and the load, compared with the conventional control method, a large number of cables originally connected to the ordinary switch are saved, the installation time is also shortened, and labor costs are saved.

4, extend the life of the lamp The fatal cause of the lamp damage is the overvoltage of the grid. The higher the working voltage of the lamp, the more its life is reduced.
· HDL-BUS Smart Environment Art Lighting System can successfully suppress the surge voltage and surge voltage of the power grid, so that the lamps will not be damaged prematurely due to the above reasons.
·HDL-BUS Shiqi intelligent environment art lighting system adopts soft start and soft breaking technology to avoid the thermal shock of the filament and prolong the life of the lamp.
·HDL-BUS intelligent environment art lighting system can successfully extend the life of lamps by 2~4 times, which not only saves a lot of lamps, but also greatly reduces the workload of replacing lamps, effectively reducing the operating cost of lighting systems. The extensive use of luminaires and areas where installation is difficult has special significance.
·Adopting intelligent lighting control system can not only meet the requirements of convenient control, lighting effects, etc., but also due to considerable energy saving effect (20%~50% power saving) and extended lamp life (2~4 times longer lamp life), It can achieve economic returns in reducing operating costs, and can save most of the power distribution control equipment required for conventional lighting, greatly simplifying and saving the work of pipe routing. In addition, intelligent lighting systems have potential value returns. For example, intelligent control systems can make the whole system work in the most comfortable state, thus ensuring people's physical and mental health and improving work efficiency.
