概述： 智能紅外語音警示柱采用C8051單片機作為處理單元，集成了 MP3、WAV 的硬解碼數(shù)字語音功放，配合廣角度紅外傳感器，驅(qū)動紅綠數(shù)碼管作為爆閃提醒。能聯(lián)動信號控制系統(tǒng)，實現(xiàn)一種與交通行人信號紅綠燈配套使用的聲響提示裝置，使行人橫穿馬路時更加注意安全，本產(chǎn)品紅外檢測靈敏，聲音指向性明確，外型美觀大方，安裝簡單。
特點： 1、采用高增益大功率的音頻放大； 2、采用紅外數(shù)字脈沖探測，感應(yīng)速度為50-700ms，警戒距離達30米，兩光束水平光軸范圍180度，上下光軸范圍20度。 3、采用不銹鋼材料通過特殊工藝處理，具有耐腐蝕、防水和防撞等功能； 4、同步紅綠燈信號顯示，強化行人過街視覺與聽覺雙重輔助提醒； 5、語音簡潔、動聽，且音量大小可調(diào)，夜間不會產(chǎn)生噪聲； 6、外形設(shè)計精致、時尚、美觀，提升城市交通品質(zhì)與檔次。
