The Research Of Intelligent Lighting Management System Of LED Based On ZigBee Wireless Technology

In order to realize the LED intelligent lighting effects and lighting to lighting places within the remote monitoring function, which need to solve these problems, such as the control command transmission, the accuracy of LED dimming, acquisition and transfer of mode illumination information and the accurate and real-time remote monitoring problems. This paper is in order to solve these problems. Following are the main contents in this paper:The Research of Zig Bee wireless network. This paper uses Zig Bee wireless communication module to build wireless communication network for information transmission of the network equipment, and setting up the network number used to identify the device information In the network equipment. In a wireless network communication level puts forward response model and random transmission mechanism, which is used to solve the problem of packet loss.The research on intelligent lighting system function.Based on the LED dimming technology, this paper presents a layered lighting intelligent control algorithm, according to personnel reign / not in place information,presupposition scenes and different time, different regions of the indoor illumination is set automatically and independent lighting control of each LED lamp group, while allowing users to personality adjustment. Finally,optimizing the process flow of the dimming control commands to improve the device operation rate and the ability of reaction.By modifying the T1 timer to output PWM wave LED dimming control in hardware implementation. PWM wave LED dimming control, and realization transformation between Control command terminal controller actually receive and the final output wave PWM dimming signal duty ratio. The concrete realization of the terminal controller according to the control command received control LED brightness and then adjust the lighting places within the illuminance value.The research on Web illumination information management platform.The remote monitoring terminal using B/S mode to build the Web illumination informationmanagement platform. The platform based on the MVC pattern of development, and using the Java SSH framework to develop,and realizing the three functions of the personnel information management, the illumination information management and LED lamp information management, to complete remote monitoring terminal for remote real-time monitoring of the lighting conditions in the system.
