一套互動智慧教室價格需要多少錢?

2019-05-27

在人工智能、互聯網等信息技術的基礎上,課堂上融合錄播、互動、評比等多種功能,實現師生之間、師師之間進行高效交流互動、協作探究,讓課堂更加生動。那么一套互動智慧教室價格需要多少錢?

一、互動智慧教室設備選型

  1、電腦:配有價格不高但性能穩定的酷睿二代處理器的多媒體電腦應該可以滿足教學需求,國產品牌如今有多款機型可選,需要注意的是硬盤容量適當大一些。掃描儀、視頻采集卡、打印機、刻錄機等設備可根據需要購買。

  2、多媒體投影機:多媒體投影機是多媒體教室的主要輸出設備,應在條件允許的情況下選擇性能較好的。有以下幾個技術指標供參考:

  (1)、亮度:現在學校用的液晶投影機多為800~1000ANSI流明左右(價格1.5~2萬),有條件的學校最好能選擇1200ANSI流明以上的冷光機型(2萬以上)液晶投影機以保證在明亮的環境中也有一個好的演示效果。

  (2)、分辨率:目前多媒體投影機的物理分辨率都可以達到SVGA(800×600),較好的可以達到XGA(1024×768),目前都可以滿足教學上的實際需求了。

  (3)、便攜性:如果經常在不同地點使用多媒體投影機,則應選擇方便攜帶的便攜式多媒體投影機;如固定在一處使用多媒體投影機,則可選擇方便吊裝、內部體積較寬敞、有良好散熱系統的多媒體投影機。在資金條件有限、場地有限的情況下,如對目前的電化教室進行改造時,也可用2~4臺70英寸或80英寸的交互智能教學一體機來代替多媒體投影機。

  3、視頻展示臺:在選擇時主要注意視頻展示臺的光學變焦最好在12X以上、最好有S端子輸出以保證較好的輸出質量。如果視頻展示臺主要用來展示實物而非文字,也可考慮用價格較低的電腦攝像頭來代替它。

  4、其他:如考慮擴展多媒體教室的功能,如政治學習、會議、舞臺、演播室等,則還需安裝一套視音頻設備(DVD視盤機、硬盤錄像機、功放、音箱等)和相關的其他設備以更好地利用多媒體智慧教室。

二、互動智慧教室的光線

  互動智慧教室大多是用多媒體液晶投影機來投影,由于學校用的多媒體投影機的投影亮度有限(1200ANSI流明以上高亮度的多媒體投影機的價格較昂貴),故在多媒體教室屏幕區的光線不能太亮(即不能有其他較強的光源照在屏幕上),但又不能為此而將整個互動智慧教室的亮度降低,因為這樣會影響視覺效果和學生的視力。一般處理方法是拉上窗簾,只開后排的幾盞燈。比較好的方法是在屏幕區不用照明,用幾個聚光燈照亮講臺和黑板,在學生區用暗藏式燈箱來保證足夠的照明亮度,四周墻壁和課桌宜用反光較小的涂料和油漆。

三、互動智慧教室的通風

  互動智慧教室由于以上光線問題而一般是不能開窗的,連續使用后,其中的空氣將會很渾濁,一來影響師生的健康,二來也同樣影響到學生的聽課效率。故在新建多媒體教室時可以考慮將靜音換氣扇組和燈箱一起安裝在吊頂中,有條件的學校可以考慮安裝帶換氣裝置的小型中央空調,對已建好或改建而成的多媒體教室可以使用靜音換氣扇組來改善通風狀況。

四、互動智慧教室的音響

  互動智慧教室的規模多為100個座位以上,故對音響也要有一定的要求。一是天花板最好能用吸音板吊頂,窗簾用可以吸音的絲絨制品,四周的墻壁最好也有一定的吸音能力;二是話筒最好選用指向性好的優質無線話筒,音箱可以放在多媒體教室的兩邊靠中后部、喇叭最好側向后方。在實際使用中如還有回嘯聲,可以衰減功放的高音、混響增益,也可以斷開音箱中的高音單元以保證擴音質量。

五、互動智慧教室的電源

  多媒體教學設備價格昂貴,為避免因電源問題會引起設備故障甚至損壞,電源問題千萬不可輕視。一是采用優質電源時序器中控、插座、開關。布線要規范,不能將開關和插座裝在老師上課時手或腳容易碰到的地方;二是對重要設備:如多媒體投影機、電腦 要使用單獨的開關,并用文字標明,以防教師誤操作;三是如所在地區供電情況不穩定,必須裝1kW以上的UPS后備電源,以減少突然的斷電或電壓不穩對設備性能的影響。

  按以上的配置目前市場價格,每間普通互動智慧教室的設備價格約17.5萬元。(各地區不一樣,價格也有差異。)
