Design And Research Of Intelligent Control System For Solar LED Street Lamp

With the continuous progress of science and technology and the rapid economic development,energy and environmental situation is increasingly grim,low-carbon environmental protection,ecological development has become the trend of urban development.Solar energy is an ideal clean energy,LED lighting is an efficient,energy-efficient lighting technology,the combination of them has emerged a new energy-saving product-solar LED lamp.Compared with the traditional street lighting system,solar LED street lighting system has high efficiency,energy saving,environmental protection and other advantages,and it gradually become an important part of modern urban road lighting.The traditional lighting system,most of which only use sub-time lighting and manual control of a single control mode of operation,so that control is relatively simple,and it can not effectively monitor the running status of street lamps,and thus it can not be achieved for the wisdom of urban development needs.It is based on this situation designed a set of stable performance,rational use of solar energy on the battery charge and discharge,and LED lamps can achieve a variety of control of intelligent street lighting control system.In this paper,the composition of the intelligent control system of solar LED street lamp is introduced in detail,and the overall design scheme of the control system is expounded.The relevant principle and output characteristic of the solar cell power generation are also analyzed and analyzed.In view of the functional requirements of the control system,LED street lamp control system includes the hardware circuit module design and software programming design two parts,and in the form of sub-module control system to achieve the function.For the hardware part of the system,the design of the solar charging module,LED driver circuit module to cypress company CY8C4247AZIM485 chip for the master chip MCU module and ZigBee wireless communication module.Solar charging part of the company is a TI company dedicated to the use of solar charging BQ24650 chip,divided into pre-charge,constant current,constant pressure three stages for the battery charge;For the control of LED lamps using time control,light control a variety of ways to control,the combination of wireless remote monitoring and control means,and the use of PWM dimming technology,intelligent adjustment of LED lights.In the software part,the preparation of the host computer interface,the use of ZigBee wireless communication technology,LED street lamp terminal running status monitoring andcontrol.At the end of this paper,the experimental platform is built and the system is tested to verify the feasibility of the control system.
