智慧教室系統

智慧教室系統
一、智慧教室系統

智慧教室由多媒體中控、智慧教室終端、智能物聯及其他多媒體教學設備組成,后端則依靠集控云平臺、雨課堂、錄播及遠程互動、資源云平臺等先進技術構建的一個以課堂教學為中心,支撐教與學全過程的生態圈。服務教師開展多種教學模式,為師生建立了一個網絡學習空間、資源空間、物理空間、社區空間多位一體的教與學環境,開展以學習者為中心的個性化學習指導。支撐了學校教學、教學管理全過程的數據采集、記錄、呈現、分析。以準確的數據統計和分析結果為教學質量提升、學習模式改進、領導決策提供支撐。

這些系統融合、聯動、互通、協同,形成一個智慧的教學環境,為授課、學習、探究等提供多方位的智能服務。

二、智慧教室系統特點:

1、多重測算的智能導播技術

采用基于老師運動檢測算法、學生運動檢測算法和PPT翻頁檢測算法,智能地進行自動錄制導播。當老師講課時圖像顯示老師單畫面;當老師與本地學生互動時,圖像應顯示老師與本地學生的合成雙畫面。

2、基于圖像分析的跟蹤拍攝

無論是教師在上課時快速走動還是在板書,一位學生或有多位學生同時回答問題,系統均能準確無誤的采用不同策略自動變焦跟蹤拍攝,整個拍攝過程教師與學生不需要佩戴和操作任何設施,畫面連續、穩定、平滑,輸出非常穩定。

3、專業數字音頻處理系統

采用業界先進的專業數字音頻處理器,配合吊麥,保證360度拾音。并應具備調音臺、音頻矩陣、回聲抑制器、反饋抑制器等多種應用功能,滿足教室環境內音頻的數字處理并本地擴音,支持會場或教室噪音抑制、嘯叫抑制、回聲消除。

4、提供多種不同清晰度的畫面效果

可以提供多種不同清晰度的畫面效果的直播應用,以適應不同的網絡條件,可在地市、市縣所下轄的學校在自己的網絡內進行直播。錄制課件除在本地錄播服務器直播外,也應可自動上傳至省各級資源管理發布平臺,實現在平臺的統一大規模直、點播。

5、屏幕共享

老師可以任意將講臺電腦或筆記本屏幕推送給所有學生,也可以選擇將某個學生的屏幕共享到大屏上,并推送給所有學生。學生在得到老師許可后也可將手機/電腦上的內容分享到大屏上,并推送給所有學生。在屏幕共享情況下,被共享的屏幕上的每個操作都將被采集和發送。可用教學操作演示,心得分享和圖片共享。
智慧教室的應用

三、多媒體中央控制器在智慧教室的應用:

1、一鍵開啟與一鍵關閉:可通過控制面板一鍵開啟或關閉整個教室的電器設備,如:燈光、投影機、電動幕布、電動窗簾、音視頻設備、交互一體機、電腦、拼接屏、LED屏等。也可根據智慧教室的層級進行關閉,如先關投影機,待投影機燈泡冷卻后才關閉電源,或先開投影機再開電腦及相關軟件,先關功放再關音箱等。

2、燈光控制:智能云控主機可通過本公司自主研發的智能自發電開關分區域或整體控制所有燈光開關。也可以做到來人感應開關燈及播放視頻時教室燈光的明暗調節控制。

3、投影機開關機控制:可以通過RS232串口或投影網絡IP地址對投影儀開關機控制,快門開關及其它信號的切換控制,可以一次控制同種類的多臺投影機的開關等。

4、紅外設備控制:可以通過智能中控自動學習紅外,控制與紅外相關的所有設備的信號,如:電視機開關機,頻道切換、空調溫度調節、無線投屏等。

5、音頻控制:可對AV\VGA\RGB音視頻矩陣切換器、影音聯動播放、背景音樂、IP廣播音量控制、無線話筒等進行控制。

6、課程錄制與集中管控相結合:通過智能中控系統實現多媒體互動教室、錄播教室、視頻直播、設備資源管理等多種功能,實現每一間教室的遠程導播、設備開關控制、公告信息發送。此外,具備多媒體教室設備集中管理功能,可遠程控制多媒體設備及計算機開關機。
