光伏电源在照明路灯中的应用
摘要
能源是国民经济发展的重要基础之一,随着国民经济的发展,能源的缺口增大,能源安全及能源在国民经济中的地位越显突出。能源问题不仅表现在常规能源的匮乏不足,更重要的是化石能源的开发利用带来一系列问题,如环境污染,温室效应都与化石燃料的燃烧有关。因此,人类要解决上述能源问题,实现可持续发展,只能依靠科技进步,大规模地开发利用可再生洁净能源。
Photovoltaic Power for Lighting Street Lamps
ABSTRACT
Energy is the important basis of the development of national economy, with the development of the national economy, the energy gap increases, energy security and energy in the position in national economy is more prominent. The energy problem not only in conventional energy deficiency, is more important than fossil energy development and utilization has brought a series of problems, such as environmental pollution, greenhouse effect and the burning of fossil fuels for. Therefore, human beings to solve the energy problem, implementation can develop continuously, rely on progress of science and technology, large-scale development and utilization of renewable clean energy. Solar energy is a new energy and an important part of renewable energy, solar power in the street lamp system application has become more and more perfect.
This design is in such a background, to complete a single chip microcomputer as the core of photovoltaic power lighting lamp control system, the controller through the battery voltage, the charging current and other parameters of the detection, control switch off, to realize charge and discharge control and protection function, realize the automatic switch of lighting system. This paper introduces the hardware and software of the system, using PWM technology to charge the battery management, ensure the battery work, realize the opening and the closing of the LED road lamp. Compared with former controller, this controller with low cost, high reliability.
