style="text-indent:25px">BLE藍牙模塊芯片極小，可以直接嵌入數(shù)字電表中。其工作采用2400～2483.5MHz的ISM(工業(yè)、科學和醫(yī)學)頻段，這是因為該頻段內(nèi)沒有其它系統(tǒng)的固定信號干擾，同時頻段向公眾開放，頻段在全球范圍內(nèi)有效。但同時ISM頻段作為開放頻段，使用其中的任何頻段都會遇到不可預測的隨機干擾源(如某些家用電器、無繩電話和汽車開門器等)。因此，對外部和其它藍牙用戶的干擾源用不同的技術加以處理。如：采用跳頻技術，抗信號衰落;采用快跳頻和短分組技術，減少同頻干擾，保證傳輸?shù)目煽啃?采用前向糾錯(FEC)編碼技術，減少遠距離傳輸時的隨機噪聲影響;采用FM調制方式，降低設備的復雜性等。目前藍牙技術的傳輸速率設計為1MHz，以時分方式進行全雙工通信，其基帶協(xié)議是電路交換和分組交換的組合，完全滿足電表收費中的實時性的要求。BLE藍牙模塊主機可以長時間處于睡眠模式，并且只在主機需要執(zhí)行時才會被控制器喚醒。</p><div

style="text-indent:25px">智能門禁鎖是在原有門禁系統(tǒng)的基礎上，增加BLE藍牙模塊，實現(xiàn)手機藍牙協(xié)議對接。湖州藍牙集成模塊市面價</p><p style="text-indent:25px">在實際應用中，會需要進行BLE藍牙模塊的選型：我們關注的就是它的傳輸速率，傳輸速率通常是首要考慮的，因為它關系到傳送的信息類型；其次，藍牙傳輸距離是一個重要的考慮因素，當然距離越遠越好；然后，還要考慮功耗，功耗主要是由傳輸速率和距離來決定；再者，就是芯片，這直接決定著藍牙模塊的運算能力；然后，接口的選擇，建議客戶根據(jù)不同需求選擇不同的接口類型。藍牙模塊的作用簡單來說就是以無線連接取代有線連接，將固定和移動信息設備組成個人局域網(wǎng)，實現(xiàn)設備之間低成本的無線互連通信。BLE藍牙模塊主要應用包括：定位標簽，資產(chǎn)追蹤，運動及健身傳感器，醫(yī)療傳感器，智能手表，遙控器，玩具等。湖州藍牙集成模塊市面價</p></p><br
