Design Of Control System Of Wind-solar Street Lamp Based On Zigbee

As the current energy crisis has intensified,humans have begun to accelerate the development and utilization of new energy sources.Among them,the scenery complementary street lamp is one of the important applications.This paper first introduces the development status of wind and solar complementation at home and abroad,and designs the overall structure of wind-solar complementary street lamps according to the flow of energy and the monitoring of the whole system state information,and analyzes the generation and management problems of power supply,the switch control of street lamps,and the system.Control and transmission of street light status information.Then introduced the overall structure of the new street lamp,the system is mainly composed of five parts: wind power generation module,photovoltaic power generation module,control module,battery,and street light.Through the analysis of the wind turbine,the system selects the direct-drive permanent magnet wind turbine to analyze the power generation principle of the photovoltaic panel.The photovoltaic panel of the system is made of polysilicon material.This system uses a lead-acid battery,which is judged according to the state of the battery.In the choice of street lamps,the system selects the LED street light with the highest brightness and low energy consumption as the lighting device of the system.In terms of system control,the system uses the CC2530 from Texas Instruments as the main controller.In the design of the battery charging circuit,it mainly performs voltage regulation processing through the BUCK circuit,and controls the charging of the photovoltaic battery.Since the voltage required for each module is not completely the same,it is necessary to perform voltage transformation processing on the output voltage of the battery.Meet the needs of each module.Finally,the terminal voltage of the street lamp and the battery lamp is collected as an indicator of the health of the system.On the communication module,the system uses Zigbee LAN and remote communication to transmit the collected data to the remote monitoring center.Among them,the remote communication uses the mobile M6312 chip.At the same time,ONE/NET is launched in conjunction with mobile to serve as the operation interface of the remote monitoring center.The software part is designed according to the corresponding flow chart of the power supply module,and the Zigbee information transmission flow chart is designed according to the transfer structure between the information.With the help of ONE/Net,an operation interface is designed,which is convenient for maintenance personnel to grasp the whole system and the status between each module in time.
