SCM based street lamp control system design
Abstract
Microcontroller street light control system is a kind of new intelligent control system, based on the energy consumption of urban street lamp now serious, high maintenance cost, the phenomenon of feedback is not timely, the design can be according to seasonal change causes the difference of the weather changes and user needs, through the button control, convenient and quick.Both the energy conservation and emissions reduction, green environmental protection, can slash spending again, reduce maintenance costs, improve the efficiency of feedback.The design embarks from the reality, the paper analyzes the urgent problems in city life now.From the practical, convenience, stability and efficiency on the system is designed.Strive to achieve maximum effect with minimal device.Occurs, the circuit of power supply, covering clock display output, keyboard input, the human body detection, noise detection, light detection, fault detection, buzzer alarm, single chip processing.With STC89C52 single-chip microcomputer as main control device for the system, different operations.Main should be combined with the hardware system.The system has a cover an area of an area small, simple to fit, not easily fail, applicability, the advantages of reasonable cost performance, can meet the size of city lighting system control of purchasing, to a large extent to achieve energy saving.
