摘要：该文介绍了一种基于51单片机的遥控智能车位锁。该锁利用无线收发模块和编解码芯片完成遥控信号的发射和接收，并通过单片机对解码信号进行有效处理后反馈给步进电机，达到车位锁自动升降的目的；为防止遥控器误操作，该锁引入超声波模块作为监测车位上方是否有车的检测单元，有效地避免了当车位上方停车时车位锁误打开造成车辆机械零件损失带来的经济损失。较手动式车位锁，该锁更为方便，同时具有防止遥控器误操作的优点，具有较高的实用价值。

Abstract： This paper introduces a remote control intelligent parking space lock which is based on 51 single chip microcomputer. The lock completes transmitting and receiving the remote control signal by using the wireless transceiver module and the coding and decoding chip. And it achieves the purpose of automatic lifting of parking spaces through the single-chip microcomputer effectively deal with the decoded signal to the stepper motor. In order to prevent the faulty operation of the remote control， the lock introduces the ultrasonic module as detection unit to monitor whether there is a car at the top of parking spaces ， effectively avoid economic losses of vehicle mechanical parts caused by opening parking lock wrongly when parking above spaces. Compared with the manual parking lock， the lock is more convenient， and has the advantage of preventing the mistake operation of the remote control， and has highly practical value.

1 背景

近年来，随着人们生活水平的提高和国内汽车价格的下降，汽车逐渐走进了普通家庭，对停车场地的需求也随之增加，停车难、乱停车问题已经成为了社会关注的焦点之一[1]，车主为防止自己的停车位被占而选择购买车位锁。但目前，市面上的大多数车位锁为手动车位锁，无论车主进停车位还是出停车位都需要下车打开或者关闭车位锁，不仅耽误时间，具有造成交通拥堵的潜在性，若遇到恶劣天气更糟糕。为解决以上问题，本文设计了一款基于单片机的遥控车位锁装置，车主在接近停车位无需下车的情况下通过手中的遥控器即可操作，相对于市面上已有的遥控车位锁，本装置的创新点在于能够防止人为的遥控器误操作造成的车辆剐蹭，有效解决了传统车位锁操作的不便并弥补了已有遥控车位锁功能不全的缺点，具有一定的经济效益。……
