Abstract：Real-time control of solar street lamps is realized in two patterns through taking single chip microcomputer as controller and combining clock circuit, optical signal detection circuit, LED drive circuit, LCD display circuit, keyboard circuit as well as infrared electric switching circuit, which possesses real-time display function of time and traffic flow. Moreover, under the normal pattern, the real-time control can automatically switch on and off the street lamps according to strong and weak light rays, while under energy saving pattern, it can automatically switch on and off the street lamps in the event of vehicles and pedestrians passing by in accordance with strong and weak light rays, whose sensitivity can be artificially regulated. While completing the design of hardware and software, problems arising in the process of system debugging such as heat dissipation of power device and selection of LED drive circuit have been profoundly analyzed and summarized. In addition, improvement measures have been put forward accordingly. Compared to the traditional solar street lamps, this design is equipped with advantages like diversified system functions and visualized display;the traditional ones exert certain reference function on the design of control system of solar street lamps.
