style="text-indent:25px">眾所周知，物聯(lián)時(shí)代，無線連接成為基本要求。在這個(gè)時(shí)代下，越來越多的物體將被連接到互聯(lián)網(wǎng)，并較終實(shí)現(xiàn)到主控端/云端的連接。隨著無線技術(shù)的迅速發(fā)展，整個(gè)市場(chǎng)已經(jīng)站在了物聯(lián)網(wǎng)新時(shí)代爆發(fā)的前夜。無論生活、工作，還是商業(yè)場(chǎng)景中，通過物聯(lián)網(wǎng)連接起來的萬物將以用戶為中心提供智能化的服務(wù)，由此也將催生一個(gè)巨大的市場(chǎng)。物聯(lián)網(wǎng)的關(guān)鍵是數(shù)以百萬計(jì)的設(shè)備，他們會(huì)集中向系統(tǒng)傳輸數(shù)據(jù)。這些數(shù)據(jù)所包含的信息可能是各種變量，如溫濕度、用戶的位置、貨物的移動(dòng)等。捕捉的信息隨后會(huì)被傳輸至云端或其他設(shè)備（即各種“物”）進(jìn)行數(shù)據(jù)交換或分析。這也意味著市場(chǎng)對(duì)高性能、***的物聯(lián)網(wǎng)無線模塊需求也將呈現(xiàn)增長(zhǎng)趨勢(shì)。在成功連接設(shè)備的過程中，連接性的角色至關(guān)重要，選擇范圍也很廣：如BLE藍(lán)牙模塊、Wi-Fi、RFID、NFC等等。我們?cè)诮鉀Q方案的選取會(huì)考慮若干因素，包括環(huán)境因素、傳感器密度、需要的連接距離和傳輸速度等。</p><p style="text-indent:25px">BLE藍(lán)牙模塊屏蔽罩的作用：手機(jī)、GPS、無線模塊電子產(chǎn)品的主板很多元件上方都焊有由金屬支架和金屬蓋組合在一起起到屏蔽作用的屏蔽罩。目前，藍(lán)牙模塊上使用一體式屏蔽罩比較多，簡(jiǎn)單性價(jià)比高，在PCB板上屏蔽靜電等對(duì)電子元件起保護(hù)作用。?屏蔽罩的原理：用屏蔽體將元部件，電路，組合件，電纜或整個(gè)系統(tǒng)的干擾源包圍起來，防止干擾電磁場(chǎng)向外擴(kuò)散;用屏蔽體將接收電路，設(shè)備或系統(tǒng)包圍起來，防止它們受到外界電磁場(chǎng)的影響。要想提升無線控制距離，單純追求高靈敏度或者增加發(fā)射端的發(fā)射功率不能完全增加控制距離，因?yàn)樵趯?shí)際應(yīng)用中會(huì)有供電、工作環(huán)境中的電磁干擾或者電源紋波干擾等因素存在，因此要綜合考慮RF接收端各類抗干擾能力。在BLE藍(lán)牙模塊上，應(yīng)選擇合理的元器件，特別是選擇硬件抗干擾方法的過程中。</p><div
