光控路灯系统的设计.doc

 摘 要 随着我国经济发展迅猛，国民对电能的使用日益提高，与此而来的就是电能的浪费。目前国内路灯照明光源一般采用高压钠灯、高压汞灯和金属卤化物灯。常出现开灯早，关灯晚；或者开灯晚，关灯早的现象，不仅造成巨大的电能浪费、影响人们日常生活，还会损害城市形象、影响社会治安和交通安全，从而影响城市的投资环境。 总之，伴着城市规模的不断扩大，现有的路灯管理的方式方法已远远不能满足城市路灯发展与管理的需要，必须依靠现代化的高科技管理手段。光控路灯开关的发明与使用就显得十分重要。本设计基于光敏电阻的基本原理，设计了一个基于光控开关的路灯自动控制系统，实现路灯的智能控制。该系统主要由内光电转换级、运放滞后比较级、驱动级等组成，通过对光控电路的设计、仿真，为最终的实际应用提供参考依据。并分析了研究过程中出现的问题，逐步找出光控开关的最佳设计方法。光控路灯开关光敏电阻光电转换 驱动电路  Abstract  As Chinas rapid economic development, increasing use of national power, and this is waste of energy. Domestic lighting generally uses high pressure sodium lamp, high pressure mercury lamp and metal halide lamps. Lights often appear early, turn off the light night; or turn the light night, turn off the lights earlier, causing huge waste of energy, not only affect peoples daily lives, also hurt the citys image, the impact of public order and safety, thus affecting the citys investment environment In short, with the urban scale expanding, existing street lamp management ways and fall far short of meeting the needs of development and management of urban streetlight, we must rely on modern high-tech management method. Invention and use of light controlling Street lamp switch is very important. This design is based on principles of photosensitive resistance, design a street lamp control system based on light switches, intelligent control for street lamps. The system within the mainly by comparison of photoelectric conversion level, operational lag-, driver-level composition, through light control circuit design, simulation, and provide the reference framework for the practical application of the final. Study on and analysis of the problems arising in the process, step by step to find out optimal design method of optical switch.
