【正文】 基于 PLC的車輛出入庫管理系統(tǒng)最大限度地提高了停車場(chǎng)的使用率，實(shí)現(xiàn)車輛出入庫控制、數(shù)量統(tǒng)計(jì)、信息查詢過程的自動(dòng)化，就顯得十分必要。采用磁卡、智能卡的車輛管理系統(tǒng)屬于前者，而采用射頻無線卡或紅外無線卡的車輛管理系統(tǒng)則屬于后者。智能小區(qū)是一個(gè)復(fù)雜的系統(tǒng)工程，車輛的智能化出入管理是智能小區(qū)的最基本也是最重要的組成部分。 我國汽車工業(yè)的飛速發(fā)展和人民生活水平的不斷提高，使得個(gè)人購買汽車日益增多。 1969 年，出現(xiàn)了可編程邏輯控制器 PLC（ Programmable Logic Controller），其特點(diǎn)是：具備邏輯控制、定時(shí)、計(jì)數(shù)等 功能，編程語言采用直觀的梯形圖語言，軟件更改方便，通用性和靈活性好。 Finally, a reduction of the processing time to avoid vehicles in the vicinity of sensors for counting from the wrong campaign. As the car, especially the increasing use of private cars, public places and munity turnover surged car, which parked vehicle safety and management of a higher demand, the introduction of advanced control technologies and 畢業(yè)設(shè)計(jì)（論文）紙 共 III 頁 第 III 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ management practices to achieve the large parking system centralized security management and intelligent control of largescale parking service management has bee a inevitable trend.
