機房動力環境監控系統——門磁監控模塊

時間:2021-01-09 16:09來源:未知 作者:小時光 點擊:

門磁傳感器器,用來探測門、窗、抽屜等是否被非法打開或移動。它由無線發射器和磁塊兩部分組成。無線門磁一般采用省電設計,當門關閉時它不發射無線電信號,此時耗電只有幾個微安,當門被打開的瞬間,立即發射1秒左右的無線報警信號,然后自行停止,這時就算門一直打開也不會再發射了,這是為了防止發射機連續發射造成內部電池電量耗盡而影響報警,無線門磁還設計有電池低電壓檢測電路,當電池的電壓低于8伏時,下方的LP發光二極管就會點亮,這時需要立即更換A23報警器專用電池,否則會影響報警的可靠性。今天就來了解下機房動力環境監控系統——門磁監控模塊。

機房動力環境監控系統——門磁監控模塊

門磁監控 

(1)系統界面




(2)機房動力環境監控系統——門磁監控模塊監控內容

對門的狀態進行實時監測,一旦被意外打開將通過監控平臺發出對外報警。

(3)實現方式

通過在門的關鍵部位安裝門磁傳感器,當有人或意外把門打開時,門磁傳感器就將報警信號傳給現場監控主機,由監控平臺軟件進行實時監測并報警。

(4)機房動力環境監控系統——門磁監控模塊實現功能

實時監測機柜門的狀態。一旦發生報警,同時產生報警事件進行記錄存儲并有相應的處理提示,并第一時間發出多媒體語音、電話語音撥號、手機短信、Email、聲光等對外報警。

多媒體語音、電話語音撥號、手機短信、Email、聲光報警可根據需要設定,異常消除時,進行恢復告警,通知用戶異常消除。
 
 
 
門磁在門禁系統中的主要作用在于以下幾點:

在機房動力環境監控系統——門磁監控模塊軟件實時監控時,可以看到每個門現在的狀態是開著的還是關著的。

可以配合門禁控制器啟用 門被非法闖入(沒有刷卡或者按按鈕的合法操作,而門被打開了,例如踹開或者撬開)報警。

可以配合門禁控制器啟用 門長時間未關閉報警等

備注:如果不需要這幾個功能的門禁系統,可以不接門磁。如果需要這幾個功能,就將門磁接到控制器的門磁輸入點(例如 S1 GND)上,不用區分正負。如果一個大型多門門禁系統,只有幾個門用到門磁的這幾個功能,則其他的門磁輸入點(例如 S1 GND)用導線進行短接,避免產生誤報警信號。
