An Intelligent Comfort Lighting System Based On Internet Of Things

Intelligent lighting system can be found everywhere in our life, a good intelligent lightingsystem can not only save maximum illumination, but also can create a good and comfortableworking environment, so as to improve the work efficiency. In recent years, our country isenergetically promoting energy conservation and environmental protection, vigorously supportthe development of energy conservation and environmental protection industries. But at present,the development of the domestic energy conservation and environmental protection industry isnot very desirable, and there are still some distance for the requirement of the modernization ofenergy conservation and environmental protection, and the use of some energy saving systemfocusing on energy saving at the same time ignoring the different people’s demand for light.This system is designed for the energy saving and personalized requirements, it is applied theZigbee communication technology, RFID radio frequency identification technology, RFIDpositioning technology, configuration technology, distributed technology etc. It setscommunication systems, an energy system, automatic control systems, management systems andservices in a system, and has the characteristics of energy saving, intelligent, remote control etc.It uses an improved LANDMARC indoor positioning technology, accurate judgment of theuser’s spatial location, and uses the particle swarm optimization (pso) algorithm, based on thecharacteristic of its rapid convergence for lighting control strategies in a timely manner. Systemthrough the sensor to collect environmental data and the user’s light information in the rfid tags,and through the Zigbee wireless AD hoc network to upload the collected information to theservers, and the servers make strategy of energy conservation and control the brightness of thelighting base on the user’s comfort lighting requirements.This paper mainly studies the design of distributed system, indoor localization algorithm,and interactive control strategy and software design process. Different parts in the design ofdistributed system based on the system function of independence and building control regionalcharacteristics, using the master-slave mode, reduce the burden of the single server already, andsimplifies the control protocol of distributed system; In the indoor localization algorithm introduces the concept of critical space area, very good to avoid the critical section positioningcaused by wrong space; In the interactive control strategy uses particle swarm optimizationalgorithm with constrained conditions, lighting system combining its own characteristics havesolved the problem of strategy in the personalized lighting; Adopted in the software design forthe design of the interface, the functions of the parts of the detailed design of the software, anddescribes the realization of each function. At last, the paper through an experiment to verify thefunction of the system.
