基于單片機(jī)的交通燈控制

1、第I頁基于單片機(jī)的交通燈控制摘要本系統(tǒng)采用MSC51系列單片機(jī)Intel8051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8051芯片的P1口設(shè)置紅、綠燈燃亮?xí)r間的功能；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)、操作簡單、擴(kuò)展性強(qiáng)。關(guān)鍵詞：單片機(jī)；交通燈；控制器；第III頁目錄1緒論......................................
