1）現(xiàn)場設(shè)備層主要是連接網(wǎng)絡(luò)中用于漏電及溫度信號(hào)采集測量的各類型的漏電火災(zāi)探測器，也是構(gòu)建該監(jiān)控系統(tǒng)必要的基本組成元素。不僅肩負(fù)著采集數(shù)據(jù)的重任，同時(shí)也是執(zhí)行后臺(tái)控制命令的終端元件。
2）通訊控制層主要是由協(xié)議接口轉(zhuǎn)換器及總線網(wǎng)絡(luò)等組成。該層是數(shù)據(jù)信息交換的橋梁，不同的接口轉(zhuǎn)換器件提供了RS232、RS422、RS485、SPABUS等及以太網(wǎng)等各種接口，組網(wǎng)方式靈活，支持點(diǎn)對點(diǎn)的通訊、現(xiàn)場總線網(wǎng)絡(luò)、以太網(wǎng)等類型的組態(tài)網(wǎng)絡(luò)。協(xié)議接口轉(zhuǎn)換器主要用于直接對現(xiàn)場漏電火災(zāi)探測器表轉(zhuǎn)達(dá)上位機(jī)的各種控制命令，并負(fù)責(zé)對漏電火災(zāi)探測器回送的數(shù)據(jù)信息進(jìn)行采集、分類和存儲(chǔ)等工作，如溫度/剩余電流等。
3）管理測控層是針對監(jiān)控網(wǎng)絡(luò)的管理人員。該層直接面向用戶。該層也是系統(tǒng)的最上層部分，主要是由電氣火災(zāi)監(jiān)控系統(tǒng)軟件和必要的硬件設(shè)備如計(jì)算機(jī)、人機(jī)界面、打印機(jī)、UPS等。其中軟件部分具有良好的人機(jī)交互界面，通過數(shù)據(jù)傳輸協(xié)議讀取現(xiàn)場各類數(shù)據(jù)信息，自動(dòng)經(jīng)過計(jì)算處理，以圖形、數(shù)顯、聲音等方式反映現(xiàn)場的運(yùn)行狀況，并可接受管理人員的操作命令，實(shí)時(shí)發(fā)送并檢測操作的執(zhí)行狀況。
3.2 工作原理
其基本原理是，當(dāng)電氣設(shè)備中的電流、溫度等參數(shù)發(fā)生異?；蛲蛔儠r(shí)，終端探測頭(如剩余電流互感器、溫度傳感器等)利用電磁場感應(yīng)原理、溫度效應(yīng)的變化對該信息進(jìn)行采集，并輸送到監(jiān)控探測器里，

經(jīng)放大、A/D轉(zhuǎn)換、CPU對變化的幅值進(jìn)行分析、判斷，并與報(bào)警設(shè)定值進(jìn)行比較，一旦超出設(shè)定值則發(fā)出報(bào)警信號(hào)，同時(shí)也輸送到監(jiān)控設(shè)備中，再經(jīng)監(jiān)控設(shè)備進(jìn)一步識(shí)別、判定，當(dāng)確認(rèn)可能會(huì)發(fā)生火災(zāi)時(shí)，監(jiān)控主機(jī)發(fā)出火災(zāi)報(bào)警信號(hào)，點(diǎn)亮報(bào)警指示燈，發(fā)出報(bào)警音響，同時(shí)在液晶顯示屏上顯示火災(zāi)報(bào)警等信息。值班人員則根據(jù)以上顯示的信息，迅速到事故現(xiàn)場進(jìn)行檢查處理，并將報(bào)警信息發(fā)送到集中控制臺(tái)。
