【正文】 y The following advantages:（1）hardware and software protocol pletely open, perfect, mon good.（2）lines at both ends of transformer isolation, immunity to interference, lightning protection performance.（3）transmission speed. （4）The system capacity is almost unlimited, the system will not increase the emergence of unexpected failures.（5）as an information transmission medium, a large number of sophisticated equipment for general use. Power Line Carrier transmission Use of electric power line carrier transmission of information transmission network, without laying a single line for data transmission of the signals can be applied to new construction, expansion of the project, and especially for reconstruction projects. Power line carrier transmission in the current fluctuations due to power lines, data transfer rate and reliability of data transmission by a greater impact, reducing efficiency. When the monitoring equipment for a long time, no reliable data transmission may cause the system to a standstill. Radio frequency transmission Radio frequency transmission of information using wireless radio transmission network as the system can not only satisfy the functional requirements, indoor no wiring, simple construction, can save the construction investment for new construction, expansion of the project, and especially for reconstruction project. RF operating frequency consistent with standards. The scope of application of intelligent lighting control systemThe scope of application of intelligent lighting control system Lighting control system can be incandescent, fluorescent, energy saving lamps, quartz lamps and other light dimming the lights on all occasions to control the environment to meet a variety of lighting requirements.（1）offices, schools, hospitals, factories and other places of the lighting system, using the time control system on the light on, turn off the automatic control, the use of illumination sensor that automatically adjusts the illumination, energy conservation. Can be the central monitoring and control system can be connected with the construction equipment.（2）Theatre, conference rooms, clubs and other places of use of system functions and dimming the scene switches can be easily converted a variety of lighting scenarios, multipoint control. Light source can be controlled through the system, air conditioning, electric fans, electric curtains, Canada Heater and other electrical equipment.（3）The venue sports venues match required by hierarchical control, large venue should be a single light control.（4）The municipal works, squares, parks and other outdoor public places, the group using the system control software can control lighting throughout the region, the use of illumination sensors, time switches to achieve lighting automation control, system monitoring software using intelligent lighting control.（5）areas where street lighting should be based on the geographical location and seasonal variation to determine a reasonable time to switch lights and the sky brightness changes according to the necessary amendments, the use of light control and time control of a bination of intelligent control.（6）Landscape lighting used in peacetime, the gene
