摘　　要：交通信号灯控制器通过控制十字路口红、黄、绿灯的亮灭,来指挥车辆和行人的安全通行。基于Multisim14仿真软件,结合实际需求,对十字路口交通信号灯控制器进行设计。倒计时计数模块采用两片减计数器件74LS192和三片8路同相三态双向总线收发器74LS245控制十字路口红、黄、绿灯的亮灯时间;D触发器与三态输出四总线缓冲器74LS125、门电路集成芯片74LS00、74LS04等组成主控电路,对红、黄、绿3种信号灯的工作状态进行转换。与传统的电路设计方法相比,运用Multisim软件设计电路具有省时、低成本、高效率的优势。The traffic signal controller directs the safe passage of vehicles and pedestrians at intersections by regulating the illumination and extinguishing of red,yellow,and green lights.Based on Multisim14 and combined with practice,this paper makes a simple design of crossroads traffic light.The countdown counter uses two 74LS192 and three 8-road in-phase three-state two-way bus transceiver 74LS245 to control the time when the red,yellow,green lights are turned on;D trigger and three-state output four-bus buffer 74LS125 and gate integrated chips 74LS00,74LS04 form the main control circuit to convert the working states of red,yellow and green signal lights.In comparison to traditional circuit design methods,the utilization of Multisim software for circuit design offers advantages in terms of time efficiency,cost-effectiveness,and operational efficiency.
