1、Intelligent Lighting Control System Abstract: This paper describes the development of lighting control systems, intelligent lighting control system mainly System functions and applications are discussed. Key words: intelligent lighting control bus transfer protocol green energy 1、 Introduction With
2、the continuous development of our economy, rapidly rising living standards, people working and living environment have become increasingly demanding, while the lighting system requirements have become more sophisticated, the traditional lighting technology has been a strong blow. On the one hand bec
3、ause of information technology and computer technology changes in lighting technology, providing technical support； the other hand, due to energy shortage, the state more and more attention on energy-saving lighting, new lighting control technology to develop rapidly to meet with By energy conservat
4、ion, comfort, convenience requirements. Lighting control lighting control from the traditional manual method, automated lighting control to todays intelligent lighting control. Intelligent lighting control system is based on computer-controlled all-digital platform, modular, distributed bus control
5、system, the central processor modules communicate directly through the network bus, the bus makes use of lighting, dimming, blinds, scene control to achieve intelligent, and become a complete bus system. Can be based on changes in the external environment in the device automatically adjust the statu
6、s of the bus to reach safety, energy conservation, human effects, and can use in the future, in accordance with the requirements of users through the computer re- Way to increase or modify the systems functionality, without having to re-laying of cables, intelligent lighting control system, high rel
7、iability, flexible control, lighting control is the traditional way can not be done. 2.1 The basic components and monitoring the contents of the system 2.1.1 System components Intelligent lighting control system is usually dimmer module, switch module, input module, the control panel, liquid crystal
8、 display touch screen, smart sensors, PC interface, time management module, hand-held programmer, monitoring computer (need to bridge a large network connection) and other components composition. 1) The basic principle of the dimming module is a microprocessor (CPU) The size of the opening angle con
9、trol SCR to control the average amplitude of the output voltage to adjust the brightness of light sources. 2) switch module is controlled by the power switch relay output to control light. 3) input module is to accept passive contact signals transmitted to the microprocessor via the bus. 4) The cont
10、rol panel is intuitive operation for control of lighting scenes were the parts, which is controlled by a microprocessor, can be programmed to complete a variety of different control requirements. Enter symbol identifying the microprocessor, after processing control information sent via the bus, to c
11、ontrol the corresponding dimming of the light source module or switching module control the dimming or switch control. 5) The illumination of the sensor interface module for connection to detection, there is detection, motion detection and other sensors. 6) Time Management module control system with
12、 another device on the bus interface to automate tasks and time control. 2.1.2 Monitoring Contents 1) The central control system through the central station and the system software on the switch, dimming, clock, lighting, monitoring and management of the state. 2) switch control, by the central stat
13、ion, local control panel for lights for open, close control. 3) dimming control, by the central station, local control panel for lighting the illumination from zero to maximum control. 4) The time clock control system based on pre-set time for light to open and close control. 5) The astronomical clo
14、ck control, enter the local latitude and longitude, the system automatically calculate the day of the sunset time, this time to control lighting according to the scene changes. 6) The scene control, through the central station, local control panel programming, lights were on, off, dimming control se
15、ttings. 7) Remote control, remote control via hand-held control panel with infrared light for the region under the control turned off, dimming control. 8) The illumination system according to the illumination detection sensor detection data (light, light and dark), in accordance with the pre-set par
16、ameters to automatically turn on lights, turn off, dimming control. 9) exists, motion control, according to presence detection, motion detection sensors and other detection data, in accordance with the pre-set parameters to automatically turn on lights, turn off, dimming control. 10) joint control,
17、through the input module receives the video security monitoring system, intrusion alarm systems, access control systems, automatic fire alarm system in the coordinated control signals to switch on the light source control or dimming control. 11) Remote control, lighting control through the Internet
18、for remote monitoring and control system: including lighting box lighting system parameter setting changes； on the system to monitor the state of the scene illumination； state of the system to control lighting scenes. 12) Graphic control, users can use the electronic map function on the entire regio
19、n for visual control of the lighting, the floor plan of the whole building can be entered into the system, and use different colors to represent the current state of the region. 2.2 Intelligent lighting control system data transmission In the international lighting control system data transmission n
20、etwork without uniform standards, the current way of the main twisted pair, power line carrier transmission and three types of radio frequency transmission. These three transmission data rates, reliability of transmission is quite different. 2.2.1 twisted-pair transmission To twisted pair transmissi
21、on twisted pair transmission network for information, the laying of lines separately for new construction, expansion of the project. There are in this way The following advantages: 1) hardware and software protocol completely open, perfect, common good. 2) lines at both ends of transformer isolation, immunity to interference, lightning protection performance.
