Design And Development Of Cloud Management And Control System For Smart Lighting Of City Road Based On Internet Of Things

For the construction of smart city,combined with LED lighting,internet of things(IOT),and cloud platform technology,a cloud management and control system for smart lighting of city road based on IOT is designed and developed in this dissertation,to provide systematic solutions for the energy saving,comfort,and intelligent construction of city road lighting.The main work of this dissertation is as follows:(1)The research status and developing trend of city road lighting system at home and abroad are summarized.According to the design standards of road lighting and functional requirements of smart lighting,the design scheme and feasibility analysis of cloud management and control system for smart lighting of city road based on IOT are given.(2)The LED lamps based on IOT is designed and developed.With the needs of lower junction temperature,higher luminous efficiency,and longer life,such lamps possesses the following advantages,including luminous efficiency greater than 100Lm/W,temperature rising below 60 degrees,driving LED with constant current,0?100%smooth illumination adjustment of LED by PWM control,and two-way communication through RS485 interface.(3)The measure and control device based on IOT is designed and developed.Such device takes embedded microprocessor STM32F103 as its core,has manual/local/remote three operating modes,monitors and warns the state of light,the current of light,environmental illumination in real time,and can achieve self-organizing network of multi measure and control devices by ZigBee uplink communication under the same controller,as well as organizing network of multi LED lamps by the downlink communication of RS485 interface.(4)The controller based on IOT is designed and developed.This controller takes embedded microprocessor STM32F107 as its core,has local setting/remote control two operating modes,can achieve multi-controller networking by GPRS/RJ45 uplink communication,self-organizing network of multi measure and control devices by ZigBee downlink communication,and possesses the functions of data collection and transmission.(5)The cloud management and control platform for smart lighting is designed and developed.This platform based on Ali cloud can store,analyze,and process a lot of lighting information,and achieve the visually centralized control of city road lighting by formulating intelligent management and control strategy.According to the design standards of city road liaghting and the design goals of the system,a set of scheme is given to test the function and performance of the designed system.The testing results show that our system achieves the desired goals,realizes the intelligent monitoring and visual operation and maintenance of city road lighting in real time,and can achieve the maximal energy saving by the intelligent management and control strategy under the precondition of ensuring the road illumination.
