摘要
为了提高学生的数字电子技术综合实践能力,设计交通信号灯自动控制数字电子技术实验电路。选用D触发器和555定时器作为主要器件,利用组合逻辑电路、时序逻辑电路和555定时器等方面的数字电路理论,将扭环形计数器应用到十字路口交通信号灯自动控制电路中,并利用Multisim作为设计工具进行仿真。
In order to improve practical ability for students of digital electronic technology, design traffic signal control circuit of digital electronic technology experiments.Choose D flip-flop and 555 timer as the main device.With the digital circuit theory of combinational logic circuit and the sequential logical circuit and 555 timer, an torsion ring counter be applied to the intersection traffic signal light automatic control circuit.finally,based on the circuit simulation tool of Multisim simulate traffic light automatic control circuit.
