信任咱們都對通訊質(zhì)量不穩(wěn)定,頻頻燒RS485連接器或許模塊DP口這類疑問很頭疼,由于這么的疑問較難處理,國內(nèi)許多用戶對EMC并不在意,大動干戈的從頭進(jìn)行接地網(wǎng)建造和鋪線通常很難做到。許多用戶解決疑問的辦法即是壞了換,這和咱們的大多數(shù)企業(yè)在EMC方面不太注重這一慣性有很大聯(lián)系。
自己總結(jié)關(guān)于通訊EMC方面的經(jīng)歷:
1、選用高質(zhì)量的通訊電纜。
2、電纜走線一定要契合EMC要求,不要和動力電纜走一起,穿管當(dāng)然極好;
3、接地系統(tǒng)一定要做好,接地阻值應(yīng)當(dāng)契合要求,并最佳和動力系統(tǒng)的接地分隔。
4、屏蔽電纜的接地要做好,最佳是運(yùn)用接地銅排把電纜屏蔽層直接卡在銅牌上接地,這種商品許多,包含PHOENIX,魏德米勒都有,那種把屏蔽層拉出再引較長線接地的辦法接地作用對比差。屏蔽電纜在走線中多點(diǎn)接地作用非常好。
5、RS485連接器接線時(shí),屏蔽層要卡到連接器接地片上,確保杰出接地。
6、假如運(yùn)用信號阻隔器,能夠消除由地網(wǎng)導(dǎo)致的電位差影響,就如同模擬量阻隔模塊相同。咱們能夠推薦一下這么的商品,如同對比少用!一些防雷商品也能夠運(yùn)用。
7、關(guān)于EMC環(huán)境很差的當(dāng)?shù)?,設(shè)計(jì)時(shí)最佳先考慮到,條件答應(yīng)能夠運(yùn)用光纖通訊,假如徹底運(yùn)用光纖,咱們都不必考慮走線疑問和兩地的電位差疑問了,光纖商品仍是有點(diǎn)貴。
