隨著科學(xué)技術(shù)的發(fā)展,PLC在工業(yè)控制中的應(yīng)用越來越廣泛。PLC控制系統(tǒng)的可靠性直接影響到工業(yè)企業(yè)的安全生產(chǎn)和經(jīng)濟(jì)運(yùn)行,系統(tǒng)的抗干擾能力是關(guān)系到整個(gè)系統(tǒng)可靠運(yùn)行的關(guān)鍵。自動(dòng)化系統(tǒng)中所使用的各種類型PLC,有的是集中安裝在控制室,有的是安裝在生產(chǎn)現(xiàn)場(chǎng)和各電機(jī)設(shè)備上,它們大多處在強(qiáng)電電路和強(qiáng)電設(shè)備所形成的惡劣電磁環(huán)境中。要提高PLC控制系統(tǒng)可靠性,一方面要求PLC生產(chǎn)廠家用提高設(shè)備的抗干擾能力;另一方面,要求工程設(shè)計(jì)、安裝施工和使用維護(hù)中引起高度重視,多方配合才能完善解決問題,有效地增強(qiáng)系統(tǒng)的抗干擾性能。影響PLC控制系統(tǒng)的干擾源與一般影響工業(yè)控制設(shè)備的干擾源一樣,大都產(chǎn)生在電流或電壓劇烈變化的部位,這些電荷劇烈移動(dòng)的部位就是噪聲源,即干擾源。
