Design And Implementation Of Intelligent Lighting System Based On Bluetooth Mesh Wireless Networking Technology

As a basic component of large-scale construction,industrial and mining enterprises,and home life,the lighting system generally use the traditional physical switch mode.Manually turning on and off the lighting equipment,is not only a single function,but also has poor flexibility and is not suitable for centralized management.The awareness of energy conservation is weak,and the phenomenon of people leaving lights often occurs,which is easy to cause energy waste.With the development of information technology and the demand for energy conservation and emissions reduction,intelligent lighting have become a hot research field.Intelligent Lighting as the foundation of intelligent city construction,with higher requirements for the number of Lighting access points,energy consumption and management control.The wireless communication technologies currently used in the market mainly include WiFi,ZigBee,etc.Although the traditional WiFi intelligent lighting products realize the portable control of the mobile phone,they have the disadvantage of large power consumptionand limited number of management devices;although ZigBee can realize centralized management of large-scale devices,ZigBee devices cannot be connected directly to mobile phones and must pass through additional gateways,which increases system instability.In response to these problems,this thesis aims to design a low-power,easy-to-connect,easy-to-manage wireless communication networking method,which could be used to combine with intelligent lighting systems to provide a more comfortable lighting environment for urban buildings.In other words,the goal of this thesis is to achieve the basic lighting work,with lower energy consumption and higher lighting comfort level.Bluetooth Mesh technology can achieve low power consumption,ensure the number of control nodes,and has the advantage of direct connection with mobile phones.Therefore,this thesis takes Bluetooth Mesh technology as the major communication networking technology,and combines it with intelligent lighting system to design an indoor intelligent lighting system with Android smart device as the control platform.First of all,this thesis studies the development of intelligent lighting system.Through the problem discovery and demand analysis,the design of this thesis is proposed;Then through the technical architecture design and system functional framework,the basic route of the solution development is given;Secondly,the appropriate underlying Bluetooth module is selected.Based on the underlying module,this thesis designs the wireless networking communication protocol between the modules and complete the connection between the underlying lighting devices;Finally,Develop the lighting control system of the mobile phone,complete the pairing of the mobile phone Bluetooth and the BLE(Bluetooth Low Energy)module on the underlying lighting device,and this thesis realizes centralized management and control of large-scale lighting equipment through the APP;The client system and the underlying lighting module are tested in a wireless office environment to verify the stability and availability of the intelligent lighting system.It turns out that the system designed in this thesis realizes the direct connection and centralized management of lighting equipment through the direct connection of the software upgrade of the smartphone to the lighting equipment.Compared with the existing work,the lighting system designed in this thesis has higher convenience,and has a larger network deployment scope.It can achieve low power consumption control through Bluetooth Mesh technology,and it has direct connection with mobile phones.The advantages of connectivity further enhance the user experience.
