摘要: 近年來隨著科技的飛速發(fā)展，單片機(jī)的應(yīng)用正在不斷地走向深入，同時(shí)帶動(dòng)傳統(tǒng)控制檢測(cè)日新月異更新。在實(shí)時(shí)檢測(cè)和自動(dòng)控制的單片機(jī)應(yīng)用系統(tǒng)中，單片機(jī)往往是作為一個(gè)核心部件來使用，僅單片機(jī)方面知識(shí)是不夠的，還應(yīng)根據(jù)具體硬件結(jié)構(gòu)，以及針對(duì)具體應(yīng)用對(duì)象特點(diǎn)的軟件結(jié)合，加以完善。
十字路口車輛穿梭，行人熙攘，車行車道，人行人道，有條不紊。那么靠什么來實(shí)現(xiàn)這井然秩序呢？靠的是交通信號(hào)燈的自動(dòng)指揮系統(tǒng)。交通信號(hào)燈控制方式很多。本系統(tǒng)采用MSC-51系列單片機(jī)Intel8031和可編程并行I/O接口芯片8255A為中心器件來設(shè)計(jì)交通燈控制器，實(shí)現(xiàn)了能根據(jù)實(shí)際車流量通過8031芯片的P1口設(shè)置紅、綠燈燃亮?xí)r間的功能；為了系統(tǒng)穩(wěn)定可靠采用了MAX629“看門狗”芯片，避免了系統(tǒng)因?yàn)樗罊C(jī)而停止工作的情況發(fā)生；顯示時(shí)間直接通過8255的PA、PB口輸出；交通燈信號(hào)通過PC口輸出；交通燈的點(diǎn)亮采用VT雙向晶閘管來控制，直接采用220V交流電源驅(qū)動(dòng)，系統(tǒng)實(shí)用性強(qiáng)、操作簡(jiǎn)單、擴(kuò)展性強(qiáng)。
