介绍了以CX20106为核心实现超声波的发射与接收,结合51单片机的控制和单片机外部中断查询相应信号,实现一系列操作测量两柱之间的距离。通过C语言控制比较车辆经过两柱之间时是否能安全通过从而进行相关报警。由于车速较慢故测量误差近乎没有,使得该系统具备实用性。
Introduced to CX20106 as the core to achieve the launch and reception of ultrasound, combined with 51 single-chip microcomputer control and external interrupt query the appropriate signal to achieve a series of operations to measure the distance between the two columns. Through the C language control to compare the vehicle passed between the two columns can be safely passed to the relevant alarm. The measurement error is almost nonexistent due to the slow speed, making the system practical.
