Research on Intelligent Lighting System of LED Based on Wireless Sensor Network Technology

摘要

With the development of mobile Internet and semiconductor technology, people have the increasingly strong demand for the home life of the network, intelligence and energy-saving. The household appliances, lighting, security alarm integrated into the control platform through a wireless network, realizing the intelligent control and management. Aiming at the defects of the current traditional lighting system about manual operation, complex wiring and so on which can't meet the requirements of the environmental sampling, linear dimming, the design of lighting control system of LED based on ZigBee wireless sensor network technology was presented. CC2530 chip was chosen and Mesh topology structure of ZigBee 2007/PRO wireless sensor network was used by the system to acquire real-time environment parameters in lighting scene, such as illumination, moving target, temperature, LED state and so on. With the change of environmental parameters and the preset lighting mode, the system can automatically make quick response and realize PWM linear non-polar dimming. The LED lighting control system was real-timely monitored and managed by the PC host computer based on the platform to overcome the defects of traditional lighting inefficient management and staff wastage. The results indicate that the system achieves the design goal of the realtime acquisition of environment parameters by sensor nodes, precise control by ZigBee remote control and centralized management by PC and the experimental data is ideal.
