【摘要】 基于STC89C52单片机的编程控制,模拟自动变速器转速传感器发出的脉冲信号并进行采集,转化成数字信号后在LCD显示屏上呈现出自动变速器的输入、输出转速,当达到相应的设定转速时单片机模拟驱动电磁阀执行自动换档。自动变速器结构复杂,无法生动地给学生演示其换档过程。通过模拟自动变速器的换档过程,可方便学生对自动变速器换档原理的理解。更多还原

【Abstract】 Based on the programming control of STC89C52 single-chip microcomputer,the pulse signal sent by the speed sensor of the automatic transmission is simulated and acquired,with the input and output speed of the automatic transmission displayed on the LCD screen after conversion to digital signals. When the corresponding set speed is reached,the single-chip microcomputer simulates and drives the electromagnetic valve to realize automatic gear change,which can help students understanding the principle of automatic transmission gear change.更多还原
