【摘要】 利用Proteus软件设计了一种汽车尾灯控制系统。采用555定时器产生时钟信号,用JK触发器进行计数,译码器74HC138进行译码,利用发光二极管显示尾灯的状态。完成了整体电路的设计。并在Proteus软件中对电路进行仿真,汽车尾灯在正常行驶、左拐弯、右拐弯和临时刹车等状态时能够按设计要求正常显示。最后制成成品。该系统具有结构简单,价格低廉、使用方便等特点,有一定的实际应用价值。更多还原

【Abstract】 The control system of automobile taillight is designed by using the software Proteus.The clock signal is generated by 555 timer,JK trigger is used to count,decoder 74HC138 is used to decode,the state of taillight is displaied by using the light-emitting diode.The design of the whole circuit is Completed.The circuit is simulated by Proteus,taillights of Automobile can display normally according to design requirements in normal driving,left turn,right turn and temporary brake state.The product is completed finally.The system has the advantages of simple structure,low price,convenient use and so on.it has certain practical value.更多还原
