        一、產品概述與戰略定位

    貝克EX-BH621是一款防暴型SIP(網路電話)終端,適用於存在易燃氣體、蒸氣或可燃粉塵的危險環境。與傳統類比工業電話不同,EX-BH621基於現代化的VoIP(網路語音協定)架構打造,可直接接入廠區的IP網路。
    該設備是綜合通訊系統(ICS)中的核心安全元件,定位為高耐用性終端,能承受機械衝擊、化學腐蝕和極端溫度,同時嚴格符合國際監管機構要求的「Ex」(防暴)標準。


        二、技術架構:SIP 2.0核心基礎

    貝克EX-BH621的核心是高效能數位訊號處理器(DSP),透過SIP 2.0(RFC3261)協定實現通訊管理。該技術選型具備多項核心優勢:

    • 通用相容性:可在幾乎所有主流IP程控交換機(IP-PBX)或軟交換平台上註冊為標準分機,包括思科CUCM、華為eSpace、Asterisk、亞美亞Avaya等。
    • 高畫質語音音質:工業環境向來噪音顯著,EX-BH621支援G.722等寬頻音頻解碼器,提供「高畫質語音」效果,捕捉的頻率範圍遠超傳統電話。這一特性對確保高噪音環境下的指令準確傳達至關重要。
    • 網路佈署彈性:同時支援靜態IP動態主機配置協定(DHCP),可輕鬆佈署於大型工業園區;還支援虛擬區域網標籤(802.1Q/p),能將語音流量優先於數據流量,保障低延遲、低抖動的通訊體驗。

        三、防暴設計理念與認證資質

    貝克EX-BH621的「Ex」防暴標識絕非行銷噱頭,而是一套基於安全要求的專屬工程設計方案。該設備採用隔爆型(Ex d)本質安全型(Ex ib)相結合的防暴防護方式。

        核心安全等級認證:

    • 氣體防護等級:通常達到IIC類認證,可適用於包含氫氣、乙炔在內的最易燃易爆氣體環境。
    • 溫度組別:常規為T6級,即設備即使在故障狀態下,表面最高溫度也不會超過85℃,避免成為低自燃點氣體的點火源。
    • 危險區域劃分:適用於1區、2區(氣體危險環境)21區、22區(粉塵危險環境)

    設備外殼採用精密設計的接合面「隔爆間隙」結構,可將內部爆炸壓力與火焰限制在殼體內,防止向外界危險環境擴散。

        四、硬體耐用性與工業級設計

    貝克EX-BH621的物理結構為適應爆炸性危險環境進行了全方位的長壽命優化。

        機身與外殼

    設備主體採用壓鑄鋁合金(ADC12)打造,該材料在重量、導熱性和機械強度之間實現了完美平衡;表面經過靜電粉末塗裝處理,具備以下特性:

    • 高抗腐蝕性:適用於海上鑽井平台等鹽霧腐蝕嚴重的環境,為必備特性。
    • 防靜電效能:防止靜電積聚產生電火花,規避爆炸風險。

        手柄與鎧裝連接線

    手柄採用高強度模塑塑膠製成,核心關鍵部件為不鏽鋼鎧裝連接線,其抗拉強度超過200公斤,幾乎無法被人為破壞或意外扯斷,確保緊急情況下的通訊生命線始終暢通。

        防護等級(IP等級)

    設備防護等級達到IP66或IP67,意味著具備以下防護能力:

    1. 完全防塵:有效阻止任何粉塵進入設備內部。
    2. 防水防護:可承受強力水射流衝擊,甚至短時間浸水。適用於熱帶風暴頻發的戶外環境,也可在食品加工、化工工廠中使用高壓水槍清潔。

        五、高階操作功能

    貝克EX-BH621搭載多項「工業智慧」功能,與民用級通訊設備形成顯著差異:

    • 主動降噪:採用雙麥克風技術或先進DSP演算法,過濾掉泵體、渦輪、風機等工業背景噪音,精準提取人聲。
    • 快速撥號/熱線功能:可預先程式設計,拿起手柄即自動撥打控制室或應急中心號碼。
    • 遠端管理:做為IP設備,技術人員可透過網頁瀏覽器遠端登入,修改設備參數、更新韌體、檢查設備「健康」狀態,無需進入危險區域。
    • PoE乙太網供電:可透過傳輸數據的同一條網路線纜供電,簡化安裝流程,無需額外配置防暴電源。

        六、工業適用場景

    貝克EX-BH621的多功能性使其成為多個特定行業的標配通訊設備:

        石油與天然氣煉化廠

    煉化廠內,一個微小的電火花即可引發災難性事故。EX-BH621被佈署在泵站、裝卸區、儲罐區等關鍵點位,可與呼叫系統對接,做為全廠應急廣播的終端設備。

        地下採礦行業

    採礦環境惡劣、潮濕,且常存在甲烷氣體。EX-BH621的IP67防護等級可抵禦潮濕和泥漿侵蝕,防暴認證則確保其在煤塵或瓦斯聚集環境下的使用安全。

        海洋與海上作業

    海水是電子設備的天敵,EX-BH621的鋁合金機身與專用塗層專為抵禦海上鑽井平台、化工運輸船常見的點蝕腐蝕設計。

        基礎建設(隧道與地鐵)

    在長距離鐵路隧道或公用工程隧道中,通訊對設備維護和消防安全至關重要。EX-BH621提供高耐用性的對講解決方案,可透過光纖轉換器或工業交換機實現長距離菊花鏈組網。


        七、安裝與維護最佳實踐

    為保持防暴等級的完整性,貝克EX-BH621的安裝必須使用專用配件:

    1. 防暴電纜密封接頭:乙太網和電源線的進線口必須使用認證防暴密封接頭,確保密封面的氣密性。
    2. 可靠接地:必須進行規範的接地處理,消散潛在的電湧或靜電。
    3. 嚴禁帶電開蓋:在危險區域內,設備電路通電時絕對禁止打開外殼。

        八、產品總結

    貝克EX-BH621絕非一款普通的電話,而是專業的工業作業工具。它將傳統防暴工程的堅固性與現代SIP網路電話的智慧化完美融合,在提升企業營運效率的同時,保障人員安全。對於所有在高風險環境下營運的企業而言,EX-BH621是對通訊基礎建設的可靠、面向未來的投資。

常見問題

什麼是ATEX?


ATEX是大氣可爆物的縮寫,是一套歐盟(歐盟)指令和標準,用於規範潛在爆炸性環境中使用的設備和保護系統。
這些標準旨在確保機械、電氣設備和相關部件在可能存在易燃氣體、蒸氣、霧氣或可燃粉塵的環境中不會成爲點火源。ATEX適用於歐盟境內的設備製造商和向歐盟市場出口產品的製造商。

什麼是IECEx?


IECEx是IEC爆炸性環境中使用設備認證體系的縮寫,是由國際電工委員會(IEC)開發和管理的國際認證體系,旨在促進潛在爆炸性環境中使用的設備和部件的全球貿易。
IECEx系統的核心目標是建立一套全球公認的統一標準和認證程序。這消除了製造商爲不同市場獲得多個單獨認證的需要,從而減少了貿易的技術壁壘,並確保跨地區的產品安全一致性。

Becke Telcom專注於鐵路、隧道、石油和天然氣以及海事部門的工業防爆通信,提供具有集成PA、對講和呼叫功能的PAGA、SOS和IP電話。
