【摘要】 利用超声波智能测距传感器及语音录放电路,设计了机动车倒车防撞语音提示器。当机动车倒车时,只要车后有障碍物存在,语音录放电路就能在超声波智能测距传感器的控制下,根据测量车尾与障碍物之间的距离,用不同的语句提示司机倒车。该装置用模块电路设计,安装简单,抗震能力强,工作稳定可靠。更多还原

【Abstract】 Using ultrasonic wave intelligent distance-measuring sensor and voice record-reproducing circuit,a voice anticollision-prompting device for backing an automobile is designed.If there is a barrier behind the backing automobile,the voice record-reproducing circuit,which is controlled by ultrasonic wave intelligent distance-measuring sensor,can remind the driver with different sentences according to the distance between the tailstock and the barrier.With the design of integrated structures,the distance-warning device has some advantages of simple installing,strong anti-detonation ability and working stability.更多还原
