根據(jù)題目要求,設(shè)計(jì)中我們選用雙色LED發(fā)光管比單色LED節(jié)省了空間,簡(jiǎn)化了設(shè)計(jì),并把雙色LED發(fā)光管排成箭頭形狀,作為直行和左右拐彎指示,形象直觀;選擇雙色LED點(diǎn)陣不僅可以從顏色上區(qū)別人的通行與停止,結(jié)合軟件還可以“動(dòng)畫”形式模擬人的走與停,配合語音作為行人通行的提示,形象、直觀、溫馨;采用數(shù)字編碼無線傳輸模式實(shí)現(xiàn)特種車輛檢測(cè),準(zhǔn)確、可靠性高;高分辨率(320240)大屏幕LCD實(shí)時(shí)顯示系統(tǒng)各種狀態(tài),可同時(shí)顯示日期和時(shí)間,顯示圖文信息量大,更直觀,可靠性高、抗干擾能力強(qiáng)。 Additionally built the pedestrian to pass through also matches by the image animation and the warm voice prompt。摘要:本設(shè)計(jì)以單片機(jī)為核心,采用主從雙MCU結(jié)構(gòu),以雙色LED發(fā)光管箭頭作為直行和左右拐彎指示,以LED數(shù)碼管作為倒計(jì)時(shí)指示,以雙色LED點(diǎn)陣作為行人通行的指示,以數(shù)字編碼無線傳輸模式實(shí)現(xiàn)特種車輛檢測(cè),完成了題目要求的所有功能。 Additionally built has been possible to establish the branch separately according to the traffic congestion situation and the inferior yang or male principle general time, and carried on the optimization design to the system mechanism, the integrity has been good, userfriendly was strong, the reliability was high.
