基于51单片机的声控和光控路灯的设计 ?  Design Of Acoustic And Electric Lamp ABSTRACT With the rapid development of science and technology, automation has been used in every aspect of life, but the street is a good example of. How to realize the energy saving lamp as the central processor is the main content of this design using 51 single-chip microcomputer. Through the book knowledge learning, teachers guidance and literature data access, to determine the 51 microcontroller as the main chip, then because of the need to achieve sound and light control function, it must use the photosensitive resistance and the electret microphone resistance to realize the conversion of light and sound into electrical signals, use the MCU minimum system module, voice module, optical module several modules of hardware to implement the design. The design of sound and light control module respectively through the electret microphone and photosensitive resistance will sound signals and optical signals are converted to electrical signals by 51 single chip computer can recognize to achieve sound and light control function. Through the use of drawing the system principle diagram, the whole circuit diagram, program flow chart of the knowledge and the necessary graphics simulation software, complete the system circuit design, mold design, the photosensitive sensor electric transform voice rectifier filter amplifier and programming, simulation, hardware debugging, finally designed and implemented by using 51 single chip computer that day by the light control circuit function control light does not shine, the night by the sound control circuit function control switch lights, and a delay time out. So as to achieve the purpose of energy saving and environmental protection, ultimately achieve the requirements.
