調幅模擬無(wú)線(xiàn)呼叫器<br>早期的無(wú)線(xiàn)呼叫器主要采用類(lèi)似與無(wú)線(xiàn)門(mén)鈴的調幅AM技術(shù)，只是在外觀(guān)和接收端做一些改進(jìn)。<br><img style="margin: auto;clear: both;display: block" src="http://l.b2b168.com/2020/05/31/13/202005311356005280034.jpg" alt="蚌埠樓層呼叫器供應商"/><br>降低人員成本；——呼叫系統可以實(shí)現一對一、一對多、多對一的呼叫，可以移動(dòng)接收呼叫信息，工作更加有針對性，不需要包間門(mén)口站崗待命、不需要大廳巡視等待服務(wù)請求，所以每個(gè)服務(wù)員的工作效率提高了，需要的人員減少了。如：中餐廳的包間要想保服務(wù)響應的及時(shí)性，就必須每個(gè)包間配一個(gè)服務(wù)員，用咖啡廳專(zhuān)用呼叫器后，在不影響服務(wù)質(zhì)量的前提下，每個(gè)服務(wù)員可以管理3－5個(gè)包間。<br><img style="margin: auto;clear: both;display: block" src="http://l.b2b168.com/2020/05/31/13/202005311356061318744.jpg" alt="蚌埠樓層呼叫器供應商"/><br>呼叫器分為有線(xiàn)呼叫器和無(wú)線(xiàn)呼叫器兩種，無(wú)線(xiàn)呼叫器使用較為廣泛。按產(chǎn)品技術(shù)分，無(wú)線(xiàn)呼叫器可以分為調頻技術(shù)和調幅技術(shù)，使用調頻技術(shù)的無(wú)線(xiàn)呼叫器更為先進(jìn)，使用調幅技術(shù)的無(wú)線(xiàn)呼叫器價(jià)格低廉但缺點(diǎn)較多。<br><img style="margin: auto;clear: both;display: block" src="http://l.b2b168.com/2020/05/31/13/202005311356053659044.jpg" alt="蚌埠樓層呼叫器供應商"/><br>目前市場(chǎng)上的樓層呼叫器產(chǎn)品可謂遍地開(kāi)花，質(zhì)量也是良莠不齊、甚至冒仿產(chǎn)品也不在少數，用戶(hù)如何選擇自己合適、并且物有所值的呢？<br>主要從以下幾個(gè)方面進(jìn)行鑒別：<br>一、產(chǎn)品外觀(guān)：生產(chǎn)廠(chǎng)家、日期、廠(chǎng)名等等應俱全，不要買(mǎi)所謂的“三無(wú)”產(chǎn)品；外觀(guān)要求做工精細、光潔不粗糙，有些廠(chǎng)家為了降低成本，用回料（回收的塑料）生產(chǎn)呼叫器外殼。<br>二、呼叫器性能穩定性：首先是呼叫器按鈕，發(fā)射信號必須穩定、前后一致性好，使用一段時(shí)間后信號無(wú)衰減（即呼叫距離不會(huì )變近）。使用差質(zhì)量電子元器件的產(chǎn)品會(huì )產(chǎn)生這種現象（因為在元器件銷(xiāo)售中一等品論個(gè)賣(mài)，二等品論斤買(mǎi)，這也是有些低價(jià)產(chǎn)品的由來(lái)）。其次，好的樓層呼叫器按鈕應該使用撥碼開(kāi)關(guān)的編碼，方便用戶(hù)的二次使用，以及蜂鳴器提示音等等；呼叫器按鈕必須要有良好的防塵、防潮功能<br>三、主機，要有良好的接收靈敏度且穩定，語(yǔ)音報號聲音洪亮清晰，蓄電池工作時(shí)間長(cháng)、且充放電性能好。目前市面上大多數呼叫器主機沒(méi)有專(zhuān)門(mén)的充放電電路，只是簡(jiǎn)單的加只電阻限流，使用一段時(shí)間后電池就會(huì )報廢。<br>四、正規的廠(chǎng)家生產(chǎn)都采用機器流水線(xiàn)生產(chǎn)，手工作業(yè)難以保證產(chǎn)品的一致性<br><div style="display:none;">-/gbaciei/-</div><br /><a href="http://www.ivymba.com.cn/">http://www.ivymba.com.cn</a>
