三、網(wǎng)絡(luò)的選擇
隧道監(jiān)控系統(tǒng),分布性強(qiáng),干擾強(qiáng),環(huán)境較差。網(wǎng)絡(luò)系統(tǒng)對隧道監(jiān)控安全、可靠、有效的運(yùn)行非常重要。我們分析了隧道監(jiān)控網(wǎng)絡(luò)應(yīng)用的現(xiàn)狀及歐姆龍公司的工業(yè)自動(dòng)化網(wǎng)絡(luò)體系。
在隧道監(jiān)控系統(tǒng)的結(jié)構(gòu)上,國內(nèi)公路監(jiān)控系統(tǒng)在管理體制上主要是三級(jí)管理,即管理中心、管理分中心和管理所。由于管理所不直接對隧道的設(shè)備進(jìn)行控制,因此工程界按照系統(tǒng)結(jié)構(gòu)的劃分把監(jiān)控系統(tǒng)劃分為信息層、控制層、和設(shè)備層。針對這三層網(wǎng)絡(luò),上主流的自動(dòng)化廠家都有相應(yīng)的產(chǎn)品,如表一所示。
