Research And Design Of Photovoltaic Street Lamp System Based On Internet Of Things

In recent years,with the development of urbanization and the construction of new countryside in China,the demand of street lamp is rising rapidly.And the demand is higher and higher.The traditional street lamps are also accelerating the intelligent upgrade,but the road lighting is a very huge project,which consumes a lot of energy.While the traditional fossil energy is becoming increasingly scarce,we must consider energy saving and environmental protection.Therefore,the development and utilization of new energy has become the focus of research.At present,the domestic and foreign research on the photovoltaic street lamp is still in the independent individual stage.And there are few researches on the street lamp network composed of many solar street lamps.Solar street lamp can save energy,but each individual is independent,and they are not easy for unified monitoring and management.This is a major reason for restricting the use of photovoltaic street lamp.This dissertation studies and designs a set of photovoltaic street lamp system based on the Internet of things,which is composed of multiple photovoltaic street lamp networks,multiple centralized controllers,a server and multiple monitoring terminals.In the system the real-time operating parameters of each photovoltaic street lamp can be easily uploaded to the server.The user can view the data by computer monitoring terminal software(or mobile phone monitoring terminal software).At the same time,users can also set up the parameters of each photovoltaic street lamp through the monitoring terminal software.The system can also monitor the fault of street lamp in time,which is convenient for further maintenance.In addition,the server can control the operation of each street lamp according to the control strategy,and further optimize the street lamp net to ensure the continuous and stable operation of the photovoltaic street lamp network.In this dissertation,the system is described in detail,and the main work of this dissertation is as follows:1.The characteristics of the photovoltaic street lamp system based on the Internet of things is introduced.the overall structure of the system is studied and designed,and the working principle and the components of the system are also explained in detail.2.Several kinds of Internet of things technology are compared with each other,and the ZIGBEE network is studied.This dissertation also designs the communication protocol of data transmission between the network of the system.3.In this dissertation the working principle of the photovoltaic street lamp controller and the centralized controller is introduced.A boost constant current type photovoltaic street lamp controller with networking function and a centralized controller with networking function are designed.4.The server and the monitor terminal software are introduced,and their function has been carried on the brief explanation.5.The experiment of each component is done,and the debugging of the photovoltaic street lamp system based on the Internet of things is completed.The experimental results prove the effectiveness of the system.
