The Design And Implementation Of The Smart City Lighting System

The city public lighting system is one of the important public infrastructures in the city.With the development of urbanization and the expansion of city scale in China,the energy-saving,environmentally-friendly,and efficient low-carbon green city public lighting system is the key to the current construction of smart cities.We analyze the status quo of city street lamp management,according to the principle of smart city lighting system construction and the actual lighting needs of XX district XX city of XX province.Completing the design and application of smart city lighting system in XX district of XX province.Submitting the system and running the actual data for one year.Firstly,we analyze the research background and significance of the smart city lighting system.According to the research status and the overall construction function requirements of the system,combining with GPRS and ZigBee technology,completing the construction framework and communication technology selection of the whole intelligent lighting system.The system consists of a host computer,a front-end control module and a front-end acquisition module.The host computer and the front-end control module use GPRS technology for the communication connection.The front-end control module and the front-end acquisition module are connected by ZigBee technology.The software programs of the smart city lighting system are respectively deployed on the upper computer,the GPRS module,the centralized controller module,the ZigBee coordinator and the ZigBee terminal controller.The administrator sends the command through the host computer software,and the command is transmitted to the GPRS module of the front-end control site via the GPRS network.After receiving the instruction,the GPRS module is responsible for transmitting the command to the centralized controller,and the centralized controller transmits the command to the ZigBee coordinator.The ZigBee coordinator uses the ZigBee network to send the host computer commands to each terminal controller to complete the communication and implementation of the host computer commands.Each terminal controller contains a variety of sensors,which are responsible for collecting data such as circuit status,road light intensity,and vehicle traffic.After collecting the data,the data is transmitted back to the ZigBee coordinator through the ZigBee network,and the ZigBee coordinator passes the data to the GPRS module through the centralized controller.The GPRS module uses the GPRS network to transmit back to the host computer.The PC software displays the data to the user for decision making and deployment.We complete the hardware construction of the city intelligent lighting system,the framework design of each functional module,software programming and debugging.Through the deployment and application of the system,it is proved that the smart city lighting system designed in this paper is reasonable and feasible,and can achieve the expected results.
