The Design Of Energy-saving Systemon Architectural Lighting

In recent years, with the rapid economic development of China, energy demands substantially. Severely energy consumption so that energy conservation becomes the consequent trend in economic development. Abating lighting energy is imminent because of architectural lighting depleting massive energy source every year. Based on the situation, the paper designed a LED energy saving system on building lighting. It adopted two aspects to lighting energy saving: selecting the efficient lighting device and the fourth generation LED lighting source, controlling method intelligent.The energy saving system on building lighting comprises three parts: PC, coordinator and terminal equipment. The PC host computer and the coordinator are connected through the RS232 serial port, the coordinator and terminal devices are connected through the Zig Bee wireless network. PC is used to the terminal data storage, logical judgment, real-time monitoring and send commands to the terminal control. The coordinator is used to the Zig Bee wireless network and maintenance, uploading data from the terminal sensing module, also PC for terminal control orders. The terminal LED lighting module contains a LED light source, pyroelectric infrared sensor, the driving intensity detection module, LED light source and light, Zig Bee micro controller module, RF module as a whole, the sensor module is responsible for data collection, upload data, according to the PC control commands work.First, the design according to the demand analysis of the system hardware circuit is designed, through a variety of programs are completed the circuit design, including the CC2530 microcontroller and its peripheral circuit, RF module CC2591 and LED driver chip PT4115, piezoelectric infrared sensor BISS001 and light sensor 5539, the coordinator circuit. Then, based on Zig Bee wireless network, the Z-Stack protocol designs the software, finishes the establishment of the system network and the division of task. And the terminal network equipment made important statements, because it is related to the convenience in practical application of arbitrary increase or decrease of the light equipment. Last, the PC host computer is designed, the PC host computer using VB6.0 language, the database using Access2007. The host computer to terminal equipment is controlled by regional control mode. A total of three kinds of control mode: constant illumination model, energy saving lighting mode and timing mode.Finally, a university in Changchun City as an example, the application of detection of energy-saving lighting system LED construction, and ultimately proved the energy saving energy saving lighting system LED architecture.
