摘要
为解决车辆乱停、占位这一问题,车位锁应运而生。车位主可以在不使用车位的时候将车位锁升起,以防止其他车辆的进入,同时,也可以在车辆停泊之后升起车位锁,从一定程度上起到防盗的作用。这种遥控车位锁是以AT89C51为核心处理芯片,配合编码芯片PT2262和解码芯片PT2272,实现了车位锁的遥控控制功能。为保证控制箱中电机的正常工作,该车位锁还设计了过流保护功能,当输入电机的电流超过一定的阈值,车位锁将采取相应的措施,以延长车位锁的使用时间。
In order to solve the problem of arbitrarily parking and occupying,the invention of parking spot lock is required.Parking lord can raise the parking spot lock in case that some other cars take the spot when he is away.Meanwhile,the parking spot lock has the theft-proof function.The core processing chip for this telecontrol parking spot lock is AT89C51,and cooperated with encoding chip PT2262 and decoder chip PT2272,implements the telecontrol function.Also the over-current protection function is designed,thus to ensure normal operation of the motor in control box.Over-current protection could prolong the life time of parking spot lock,for the parking spot lock could take appropriate measures when the input current of electrical machine is above a certain threshold.
