Research On Green Building's Intelligent Lighting System Based On IOT

In daily life and work,the lighting is essential to lighting control is a vital part of building control systems.With the rapid development of mobile Internet and semiconductor technology,people's network of home life,intelligent,energy-saving requirements of more and more intense.Intelligent lighting system is essential for green intelligent building and home automation subsystems for complicated wiring and scalable,single function,manual management,"the ever-burning lamps of "serious defects such as energy,traditional lighting systems have been unable to meet the demands of modern life and quality,intelligent lighting system in this context.Intelligent lighting can create a good environment,and can save energy.This paper use the ZigBee wireless communications technology wireless sensor and control networks,and use Lab VIEW to make the PC,design of fuzzy controller with intelligent lighting system,finally achieve the intelligent lighting control.Main functions include the following:(1)In view of the current characteristics of the built environment,green building intelligent lighting system using the Internet.Intelligent lighting system design focuses on the wireless sensor and control network and PC computer control center into two parts.Using pulse width modulation(Pulse Width Modulation,PWM)way of dimming.Intelligent lighting system using LED lights as the light source.Finally the system using ZigBee technology for analysis and research.(2)Based on the Internet of intelligent lighting system for green building design.Hardware includes ZigBee wireless communications module circuit design,circuit design,LED light intensity sensor driver hardware circuit design in three aspects.Among them,the ZigBee wireless communications module circuit design using TI CC2530 chip from its core modules and extended circuit module design the circuit.Light intensity data acquisition node by the CC2530 communication module and light intensity sensors,light intensity sensor is BH1750FVI.Driver hardware circuit using PWM dimming method in the design of stepless dimming of LED.(3)Intelligent lighting system software based on Internet of green building design.Research on wireless sensor and control network and PC computer control center software development environments,and ZigBee wireless sensor and control network coordinator,and ZigBee and ZigBee LED dimming of light intensity node design,PC control center of intelligent lighting system in LabVIEW for green building programs are designed.(4)Green architecture based on Internet control algorithm for intelligent lighting system.Smart dimming function for intelligent lighting system using fuzzy control algorithm and fuzzy controller with intelligent lighting system was designed,intelligent lighting system by fuzzy control algorithm of fuzzy control rulers and fuzzy control table.In actual operation,the host computer by querying the element of control with fuzzy control table to obtain the corresponding region,so you can get the output of the PWM values and PWM value is sent to the LED lighting nodes of wireless sensor and control network,eventually you can adjust the light intensity.
