声控开关电路的设计与实现

Design and simulation of voice operated switch circuit

利用三极管基本放大电路、单稳态触发器、多谐振荡器等基本电路,设计与调试声控开关电路,借助示波器和万用表等器械,对电路进行仿真分析。本电路系统采用声音控制方式进行计数,有数码管显示结果,计数范围是0～99。电路具有快捷、方便、直观和准确的优点,可用于自动控制、统计等场合。

This paper designs and debugs voice operated switch circuit by using the triode amplifying circuit, monostable trigger, the monostable multivibrator, with the help of oscilloscope and multimeter and other equipment, simulates and analyses the circuit. The circuit system counts with voice control, has digital display results, 0～ 99 is a counting range. The circuit has advantages such as fast, convenient, intuitive and accurate, and can be used for automatic control, statistics etc.
