Research Of The Solar Street Lamps Control System Base On The Power Line Communication

Along with the development of science and technology, low carbon green energy being increasingly applied to all aspects of social life. The traditional urban street lamp because its energy consumption high, short life, control system is simple and gradually replaced by solar street lamps. The current solar street lamps system although solved the problem, but rein in the street in system of intelligent and system existing defects. Utilization In view of the present situation this paper introduces a design of power carrier communication based on solar street lamps control system, this system combines power carrier communication special advantages and characteristics of solar street lamps, using the power of the carrier communication to monitor solar street lamps control system can make the control center, the operating condition of the monitoring street lamps in for the entire solar street lamps, timely and efficient operation of provides a new solution. This system can monitor street lamp working condition, timely information and control centers maintain contact for staff, provide detailed real-time information base.It firstly analyzes the solar street lamps and power carrier technology development present situation and advantages, based on this completed the solar street lamps system power carrier, according to the general scheme design of circuit design of solar street lamps system design principle block diagram of the system structure, then according to the design requirements research and detailed analysis of the system each key module of function and working principle, the choice to a single chip microcomputer AT89C2051 as the core controller, control over the system work, including the system design of power supply circuit, carrier communication module circuit, storage battery charging and discharging circuit, street lamp driver circuit, temperature acquisition circuit system hardware circuit. Mainly introduces storage battery charging and discharging circuit design, analysis the battery charge method, choose different PWM pulse modulation charging ways, ensure the battery using life. Through analyzing the characteristics of electric power carrier, research in this system to choose a suitable the carrier chip.The paper research and analysis that solar street lamps system design in software, according to the system's design requirements and design the system of software components, this software to realize the control of solar street lamps, ensure the normal work and give full play to the advantage of solar street lamps. Simultaneously according to system function design requirements, design a day and night two cases street lamps, the status of the system flowcharts on the battery mode, design system based on the charging and discharging program, extended battery service life. Final paper work was summarized, and for the further development of the system and optimization are proposed.
