Abstract
This project is based on single-chip design a
voice-activated light and alarm system in the building, by
voice-activated lights and emergency alarm which two
key components.Voice-activated light partly through
sound sensors for sound detection, and then single-chip
processing, realization of intelligent control for the light
switch.Alarm part consists mainly of beeper and keys,
when voice-activated lights fail, through touches the
pressed key realization light buzzer alarms for
maintenance tips.The hardware circuit consists of single
chip microcomputer minimum system circuit, sound
sensors module, keys module, LED display module, a
buzzer alarm circuit module;Software part mainly
accomplished by programming of C programs such as
destroy the light of lights, and then through the led
display,Alarm functions are realized by key operation.In
the design of combination of hardware and software
debugging step by step, meet the requirements of
control effect.When people walk through the stairs,
