摘　　要：针对一般小区或中小型厂矿事业单位由于成本原因没有安装照明电源时控系统,设计一套基于定时、光敏的智能路灯开关系统,由集成电路CD4060计数器芯片作为振荡、计数核心电路,利用光电管的光敏特性实现被控晶体管的通断,从而控制灯光继电器、供电接触器动作,为了延长定时时间,可利用两个大容量电解电容反接,来代替原来的无极性电容,可以取得很高的性价比。Aiming at the fact that the time control system of lighting power supply is not installed in general residential areas or small and medium-sized factories and institutions due to cost reasons, an intelligent street lamp switching system based on timing and photosensitivity is designed. The integrated circuit CD4060 counter chip is used as the core circuit of oscillation and counting, and the photosensitive characteristics of phototransistors are used to realize the switch-off of controlled transistors so as to control the lamp relay and power supply contactor. In order to prolong the timing time, two large capacity electrolytic capacitors can be inverted to replace the original non-polar capacitors, which can achieve a high cost performance.
