摘要
Abstract
Aiming at the disadvantage of traditional audio alarm,a multi audio alarm which can produce eight kinds of sound using only one trumpet is developed based on the 8-bit microprocessor Atmega8 of AVR MCU.By representing the sound data as the array of interrupt time constant and interruptions,the multi audio output of alarm was realized.The system structure and working principle of the instrument is discussed,the hardware design about the core module is described in detail.The conversion strategy of the sound and the software Systematic Implementation Method is presented.The experiment results showed that the instrument has many advantages,for example,stable hardware and reliable performance.关键词
