產品概述

面向安防與工業通信場景而設計

BM02S 針對語音互動、遠程通信與設備整合需求明顯的工業安防與通信環境而開發。它可作為 SIP 對講站、緊急求助點、廣播終端、視頻通信設備以及其他嵌入式通信產品內部的核心板使用。

其架構透過提供可直接整合的通信核心,幫助簡化產品開發。開發者無需從零分別搭建語音、網路與控制模組,而可將 BM02S 作為聯網對講與廣播設備的集中式平台來使用。

相容主流 SIP 平台

該板卡支援標準 SIP 2.0 與相關 RFC 協議,可與主流 IPPBX、Softswitch 與 IMS 平台配合使用。這種相容性使設備更容易接入既有通信系統,而無需進行繁重的協議客製化。

根據規格,BM02S 可與 Asterisk、BroadSoft、3CX、Elastix 等常見平台整合。對產品開發者而言,這意味著在面向企業語音系統、安防通信部署或行業專用 SIP 環境時具備更高彈性。

核心功能

一板實現對講與廣播

BM02S 同時支援對講與廣播功能,適合需要雙向語音通信以及單向公共音頻輸出的設備。它支援數位全雙工免提對講,有助於在日常使用與緊急場景中提供更大聲、更清晰的語音互動。

該板還支援 10W 至 30W 單聲道功放輸出,輸出功率會隨輸入電壓自適應調整。這使開發者在設計不同揚聲器需求的終端時更具彈性,從緊湊型對講裝置到高音量輸出通信設備皆可適配。

用於音視頻通信的攝像機聯動

BM02S 支援與 IPC 攝像機聯動,使終端可由音頻對講擴展到視頻對講應用。藉由標準 RJ45 攝像機介面,它可整合到需要將語音通信與可視確認結合使用的設備中。

此功能特別適合用於出入口、求助點、安保值守位置與遠端監控點等場景,在這些位置,操作人員往往同時需要語音交互與即時視頻支援。文檔還提到攝像機側支援 NVR 錄影,這對事件回溯與運行追蹤也很有價值。

一鍵呼叫與外部 I/O 擴展

該板內建緊急呼叫按鈕介面,可實現一鍵發起呼叫。這使它適合用於需要快速發起通話的通信產品,如緊急呼叫站、服務請求終端或安防通信端點。

此外,短路輸入與輸出介面使 BM02S 可與外部控制模組、報警設備或周邊裝置互動。這讓製造商能夠更直接地將語音通信與簡單設備聯動及外部觸發邏輯結合在一起。

介面與整合彈性

面向嵌入式設備開發的多種介面

BM02S 在一塊緊湊型板卡上整合了電源輸入、網路、攝像機、喇叭、Line out、錄音輸出、麥克風輸入、速撥按鈕以及短路輸入與輸出介面。這種高整合度介面設計,是其面向整合型通信終端開發的重要優勢之一。

透過減少多個獨立介面模組的需求,該板有助於縮短開發週期並簡化硬體設計。它非常適合空間、佈線與整合效率都很重要的客製化終端產品。

支援音頻、控制與除錯擴展

規格中包含麥克風輸入、帶 LED 的速撥按鈕、無源喇叭輸出、Line out、錄音輸出、UART 除錯、RS232,以及帶 DC 輸出的 4G 相關介面。這種廣泛的介面設計,使開發者能更靈活地打造不同結構與應用重點的產品。

無論最終產品是壁掛式對講機、求助點、桌面通信工作站,還是專用嵌入式終端,BM02S 都提供了音頻、控制、維護與網路擴展所需的完整連接選項。

技術優勢

標準協議與多種語音編碼

BM02S 支援 SIP 2.0 與 RTP,同時支援 G.729、G.711、G.722、G.726 等多種語音編碼。這種編碼靈活性有助於開發者在不同部署環境中平衡相容性、頻寬使用與語音品質。

在實際應用中,G.722 有助於提供更清晰的寬頻音質,而 G.711 與 G.729 等編碼則仍適用於更重視相容性或頻寬控制的系統。這使該板在不同 SIP 解決方案中具備更廣泛的適應能力。

適用於不同安裝方式的靈活供電

該板支援 12V 至 24V DC 電源輸入,同時支援 48V PoE 供電。這種雙供電方式適用於多種安裝條件,無論終端是透過標準網線部署,還是使用專用本地電源供電,都能靈活應對。

對工程團隊而言,PoE 可簡化安裝並降低佈線複雜度,而 DC 供電則在獨立式或客製設備結構中更具實用性。隨供電電壓調整的自適應功放輸出,也有助於更靈活的產品設計。

面向嚴苛運行條件而打造

BM02S 的工作溫度範圍為 -30°C 至 70°C,相對濕度為 10% 至 95%,儲存溫度範圍為 -40°C 至 70°C。這些規格顯示它可支援在多種環境條件下部署。

其板卡尺寸僅為 99 × 79 × 21 mm,也適合嵌入安裝於各類通信終端外殼中。小尺寸與寬環境適應性的結合,進一步提升了它在工業與安防設備開發中的實用價值。

對於希望在單一嵌入式平台上整合語音、廣播音頻、攝像機聯動與外部控制的開發者來說,BM02S 在功能、尺寸與系統相容性之間提供了實用平衡。

管理與維護

支援 Web 設定與在線升級

BM02S 支援透過 Web 介面進行設定與管理,同時支援配置匯出、配置匯入與在線軟體升級。這些功能對產品部署、維護效率以及長期生命週期管理都十分重要。

對系統整合商與設備製造商而言,基於 Web 的管理方式可提升調試與售後支援效率,特別是在涉及多台設備或需要標準化配置控制的項目中更為明顯。

狀態指示與實用的本地操作

該板具備啟動、註冊成功、註冊失敗、網路異常與通話中的 LED 狀態指示。這些可視化提示有助於安裝人員與技術人員在部署與故障排查過程中快速掌握設備運行狀態。

文檔還描述了恢復出廠、IP 語音播報與網路模式切換等實用本地操作。這些功能有助於現場工程師在不完全依賴遠端工具的情況下,更高效地完成設定與服務工作。

應用場景

適用於對講、求助點與廣播設備

憑藉 SIP 語音、攝像機聯動、音頻輸出與呼叫按鈕支援的組合,BM02S 非常適合用於 SIP 對講終端、緊急求助點、視頻通信設備與網路廣播終端。

對於需要穩定語音通信、靈活介面設計與成熟 SIP 系統相容性的項目,它尤其實用。這使它成為安防、公共服務與工業相關應用中客製化通信終端的良好選擇。

面向 OEM 與設備製造商的實用核心平台

對於希望更高效開發 SIP 終端、音頻對講產品或整合型通信設備的製造商而言,BM02S 可作為整機的通信核心。它有助於減少在語音、網路與硬體介面方面的重複底層開發工作。

從產品開發角度來看,BM02S 的價值在於它作為完整嵌入式通信平台的角色,而不只是單一用途板卡。它旨在幫助將設備概念更快轉化為可運行的網路通信終端。
