摘要
提出了一种停车位传感控制器.应用超声波反射原理,设计了超声波传感器发射电路和接收电路,实现了车辆有或无的检测;采用步进电机驱动作为车位锁的核心部件,应用了步进电机的驱动电路,实现了车位锁的开启与闭合控制.实验结果表明,停车位传感控制器能够自动检测停车位中有无车辆,能够顺利控制车位锁的开闭.
A parking sensor controller is proposed. The ultrasonic signal transmitted circuit and ultrasonic signal received circuit is designed to realize the detection of vehicles based on the ultrasonic reflection principle. Stepping motor, which is designed to be the core part of parking barrier, controls the open and close actions of the parking barrier on the basis of drive circuit. The results of experiment show that the parking sensor controller can detect the state of parking space and control the parking barrier automatically.
