1、I 基于 PLC 的家用车库自动门控制程序 摘 要 随着汽车产业的发展，人们对车库的需求量日益增长。智能车库将是信息 社会最重要的基础设施之一， 停车场管理控制系统则是现代建筑中不可或缺的一 部分。随着计算机控制技术的发展，停车场管理控制系统的功能及软硬件设施也 伴随其发展而不断改进。 本文主要阐述了车库自动门的设计思想与程序编制, 应 用 PLC 作为现场控制器，对现场设备进行信号采集与控制。 当自家汽车或主人进 车库时，当车进入超声波区域时，身份识别继电器工作，车库门开启，当车完全 进入车库时，延时 10 秒后车库门自动关闭；当车要出库时，位于车库内的压力 开关闭合，车库门开启，延时 30
2、 秒，车库门自动锁闭，以及实现车库的防盗、 防火、防压等诸多智能控制。 根据管理及控制功能需求，充分研究了相关系统组件的工作原理及性能指 标，据此进行系统功能设计及硬件选型。此系统对车库的管理有很大的帮助、对 疏导交通流量、提高道路通行能力有明显的效果，有很大的实用价值。 关键词： 可编程控制器，车库控制系统，车库自动门，梯形图 II ABSTRACT Along with the development of the auto industry, people on the garage ever increasing demand.
