The design of the wireless intelligent lighting control system

Abstract

To intelligently control and adjust LED lighting network system, to make use of the sensor technology, wireless communication protocol, intelligent control technology, it overcomes the difference of the various technical standard, the lack of communication that is problem to impede the promotion of the intelligent lighting. Extending the conventional control method with intelligent technology, planning scheme according to the functions, the design carried out the three respectively subsystems, then the debugging and fusion of the software and hardware. By using the method of software, the high or low level of I/O output can simulate PWM control signal whose duty cycle of the PWM can be adjusted. The brightness data collected from the environment is changed into PWM control information. Using acoustic sensors and temperature sensors and voltage sensors to further adjust the distribution curves of the light and color, these collected data are turned into PWM fine tuning signal. The wireless intelligent lighting control system designed can well solve problems such as the large regional span, the high cost of the network transmission and the uncertain of the node number.
