Solar energy-saving streetlamp based on single-chip microcomputer

Abstract

The invention discloses a solar energy-saving streetlamp based on a single-chip microcomputer. A solar cell panel charges a lead-acid battery through a charging circuit. The lead-acid battery supplies power to an LED illumination module, a clock regulation module, a clock display module, a photo-sensitive circuit and the single-chip microcomputer through voltage stabilization circuits respectively. The clock regulation module comprises a time regulation key, a time increase key and a time decrease key. The clock display module comprises two four-bit eight-section digital pipe display units. The photo-sensitive circuit senses the brightness degree of the surrounding and outputs a photoelectric signal to the single-chip microcomputer through an analog-to-digital converter. The LED illumination module is turned off when the single-chip microcomputer judges that the surrounding reaches the required brightness; otherwise, whether the time is within the illumination time period or not is further judged, the LED illumination module is turned on if the time is within the illumination time period, and the LED illumination module is turned off if the time is not within the illumination time period. The streetlamp can be automatically turned on and off according to the environment brightness and through the combination with the set time, and the energy waste is reduced.

Description

technical field [0001] The invention relates to a single-chip microcomputer-based solar energy-saving street lamp, which belongs to the technical field of lighting. Background technique [0002] With the continuous development of solar power generation technology, solar street lamps have become the new favorite of the urban road lighting industry due to their advantages in environmental protection and energy saving, with huge market potential. The existing solar street lamp control system has a single control function and general control effect, and cannot fully utilize the advantages of energy saving and environmental protection of solar street lamps. Therefore, it is necessary to provide a new solar street lamp control system that can realize more control functions and has Advantages of low cost and high integration. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a single-chip microco...
