我們生活中的門磁系統(tǒng)一般可分為門磁開關(guān)、門磁傳感器（探測器）、門磁報警器三大部分組成。一些門禁系統(tǒng)是基于智能總線和同個系統(tǒng)平臺，這樣智能家居的智能終端可以方便地接入可視門鈴系統(tǒng)門口機和管理中心，實現(xiàn)訪客對講、留言、留影和門禁功能，成為我們家庭安全的第一道防線。這些還可同時配備智能感應(yīng)卡、指紋鎖，可實現(xiàn)智能聯(lián)動，如同步撤防報警器，開啟相應(yīng)燈光或模式等。
有線門磁傳感器的工作原理
在智能家居門禁系統(tǒng)中門磁開關(guān)的作用是負責門磁通電否，通電帶磁（閉門），斷電消磁（開門），門磁安裝于門與門套上，開關(guān)安裝于屋內(nèi)，配合自動閉門器使用，一般可承受150公斤的拉力。
有線門磁為嵌入式安裝更加隱蔽，感應(yīng)門窗的開合，適用于木質(zhì)或鋁合金門窗發(fā)出有線常閉/常開開關(guān)信號。門磁是用來探測門、窗、抽屜等是否被非法打開或移動。它由無線發(fā)射器和磁塊兩部分組成。門磁系統(tǒng)其實和床磁等原理相同。這里主要以門磁為例。
無線門磁傳感器的工作原理
無線門磁是由無線發(fā)射模塊和磁塊兩部份組成，在無線發(fā)射模塊有兩個箭頭處有一個“鋼簧管”的元器件，當磁體與鋼簧管的距離保持在1.5厘米內(nèi)時，鋼簧管處于斷開狀態(tài)，一旦磁體與鋼簧管分離的距離超過1.5厘米時，鋼簧管就會閉合，造成短路，報警指示燈亮的同時向主機發(fā)射報警信號。無線門磁傳感器用來監(jiān)控門的開關(guān)狀態(tài)，當門不管何種原因被打開后，無線門磁傳感器立即發(fā)射特定的無線電波，遠距離向主機報警。
