Incondition of surface anti - corrision and insulation coat of metal and tiny hole of steel where resistance and crack is very small, when supplying a high voltage, gas crack will be punctured and electric spark discharging will occur, now send a pulse signal to the alarming circuit the alarmer can send out sound and light to alarm. we can do leak hunting on the coating according to this principle
金屬表面絕緣防腐層過薄、漏鐵及漏電微孔處的電阻值和氣隙密度都很小,當有高壓經過時就形成氣隙擊穿而產生火花放電,給報警電路產生一個脈沖信號,報警器發出聲光報警,根據這一原理達到防腐層檢漏目的。It realizes the functions of storing and transferring the information of fire alarm, displaying time, scanning keyboards, the safe maintenance of system and so on. the part of wireless communication is controlled by at89c2051 mcu, mainly realizing transmitting and receiving data between controller and other detectors. the external signals received by a wireless module are transmitted to mcu through shaping circuit, and the signals of mcu are transmitted by a wireless module through tone modulation circuit
人機交互部分以單片機c8051f020為核心,為用戶提供一個良好的操作環境,實現了火災報警信息的存儲及調用、時間的顯示、鍵盤的掃描、系統的安全維護等功能;無線通信部分由單片機at89c2051來控制,主要實現控制器與其它探測裝置之間信號的無線發射和接收,無線通訊模塊接收到的外部信號經過整形電路送入單片機,單片機發出的信號經過音頻調制再由無線通訊模塊發送出去,這樣實現了數據的無線傳輸;本文還從節能的角度出發,兼顧性能的可靠性,提出了一種合理的無線火災報警的信息傳輸模式。
