485通信線由兩根雙絞的線組成,它是通過兩根通信線之間的電壓差的方式來傳遞信號,因此稱之為差分電壓傳輸。
差模干擾在兩根信號線之間傳輸,屬于對稱性干擾。消除差模干擾的方法是在電路中增加一個(gè)偏值電阻,并采用雙絞線;
共模干擾是在信號線與地之間傳輸,屬于非對稱性干擾。消除共模干擾的方法包括:
(1)采用屏蔽雙絞線并有效接地
(2)強(qiáng)電場的地方還要考慮采用鍍鋅管屏蔽
(3)布線時(shí)遠(yuǎn)離高壓線,更不能將高壓電源線和信號線捆在一起走線
(4)不要和變頻、逆變裝置共用同一個(gè)電源
(5)采用線性穩(wěn)壓電源或高品質(zhì)的開關(guān)電源(紋波干擾小于50mV)
