Smart Lighting Control System Research Based On Internet Of Things

In recent years, with the application of modern wireless communication technology,information technology and sensor technology, the Internet of Things(IOT) and its related industry has been developed rapidly. As one of the most important application of the IOT,smart home has attracted more and more people's attention. Compared to the traditional wired home automation, modern smart home has overcome many shortcomings, such as cumbersome routes and low reliability. A more comfortable and intelligent home condition will be created by the modern smart home system in the future.At the same time, we have noticed that with the continuous development of society,the accelerating rhythm of people's life and work, many people appear more or less psychological problems.Currently, in our country, the number of psychiatrists which 100,000 individuals have is no more than five.As a psychological specific characterization,mood can affect the people around.Negative emotions will affect the harmony of the family,even the harmony of the whole society.Research and development of color psychology explain the relationship between color and psychology.In the lighting control system, the adjustment of background lighting can create different family atmosphere and make it possible to regulate the emotional and psychological feeling of people.This design of intelligent home lighting control system adopts ATmega328 as the main chip.The hardware include control module, sensor module, lighting control module, ZigBee communications module, Bluetooth module. The system proposes to regulate the body's psychological and emotional functions by adjusting the backlight colors, in addition to achieving the traditional master lighting control light intensity.The main study work and results are just as followed:(1)Construct the intelligent lighting control system Dimming platform,which includes a sensor module, communication module and lighting control module.(2)PC interface design is based on Processing language, including packet unpacking program, interface design program. Mobile terminal interface design language is based on Android, include Bluetooth connectivity module, data communication module, back-office services module, front display module interface.(3)Analysis on the relation of the household background color and emotion regulation.Experimental verification of changes in physiological parameters are well characterized on physiological mood changes.(4)Through the acquisition of environmental parameters and body parameters, to achieve the main lighting switch control, master lighting brightness control, backlight color control.
