Kumvetsetsa Kwakuya kwa RS422 Interface: Njira Yolumikizirana Yokhazikika ya Ma Module a Laser Rangefinder

Mu ntchito zamafakitale, kuyang'anira kutali, ndi makina ozindikira bwino kwambiri, RS422 yakhala ngati muyezo wokhazikika komanso wogwira mtima wolumikizirana motsatizana. Yogwiritsidwa ntchito kwambiri mu ma module a laser rangefinder, imaphatikiza mphamvu zotumizira mauthenga akutali ndi chitetezo chabwino cha phokoso, zomwe zimapangitsa kuti ikhale yofunikira kwambiri m'makina amakono osinthira.

1. Kodi RS422 ndi chiyani?

RS422 (Muyezo Wovomerezeka 422) ndi muyezo wolumikizirana wopangidwa ndi Electronic Industries Alliance (EIA) womwe umafotokoza kufalikira kwa chizindikiro chosiyana. Mosiyana ndi mawonekedwe achikhalidwe a RS232, RS422 imagwiritsa ntchito mizere iwiri yowonjezera ya chizindikiro kuti itumize deta. Kutumiza kosiyana kumeneku kumathandizira kwambiri kukana phokoso komanso kudalirika kwa kulumikizana.

2. Zinthu Zaukadaulo Zofunika Kwambiri za RS422

Njira Yotumizira: Chizindikiro chosiyana (awiri opotoka)

Liwiro Lalikulu Lotumizira: 10 Mbps (pamtunda waufupi)

Kutalikirana Kwambiri kwa Kutumiza: Mpaka mamita 1200 (pa liwiro lotsika)

Chiwerengero Chapamwamba cha Ma Node: dalaivala 1 mpaka olandira 10

Mawaya a Chizindikiro: Kawirikawiri mawaya anayi (TX+/TX)–, RX+/RX–)

Chitetezo cha Phokoso: Chapamwamba (choyenera malo ovuta amagetsi)

Njira Yolumikizirana: Kulunjika mpaka ku mfundo zambiri (dalaivala imodzi kupita ku zolandila zingapo)

3. Ubwino wa RS422

①Kutumiza Maulendo Aatali

RS422 imathandizira kutumiza deta pamtunda wokwana mamita 1200, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito komwe deta yoyezera iyenera kutumizidwa m'malo osiyanasiyana kapena zida zosiyanasiyana.—monga kufufuza njanji, kuyang'anira madera, ndi kayendetsedwe ka zinthu m'nyumba zosungiramo katundu.

②Chitetezo cha Phokoso Lamphamvu

Chifukwa cha chizindikiro chake chosiyana, RS422 imatha kuletsa phokoso la common-mode, zomwe zimapangitsa kuti ikhale yoyenera malo okhala ndi phokoso lamagetsi, monga mafakitale kapena malo omangira panja.

③Kukhazikika Kwambiri kwa Deta

Ngakhale mutakhala ndi chingwe chachitali kapena mu malo ovuta amagetsi, RS422 imapereka kutayika kwa deta kochepa kwambiri kuposa njira zolankhulirana zachikhalidwe zokhala ndi malire amodzi. Izi zimatsimikizira kuti kuyeza mtunda kumatuluka nthawi yomweyo komanso mokhazikika.

④Kulankhulana kwa Munthu Mmodzi ndi Ambiri

RS422 imalola wolandila m'modzi kulankhulana ndi olandila angapo, zomwe zimathandiza kuti makina osiyanasiyana a ma module ambiri akhale otsika mtengo.

4. Kugwiritsa Ntchito mu Ma Module a Laser Rangefinder

RS422 imagwiritsidwa ntchito kwambiri mu ma module a laser rangefinder m'zochitika zotsatirazi:

Ma Drones / Maloboti: Pamene phokoso lamkati mwa makina lili lalikulu, RS422 imatsimikizira kulumikizana kokhazikika.

Kuyang'anira Mzere Wautali: Kumene deta ya mtunda iyenera kutumizidwa modalirika kwa wolamulira wapakati.

Machitidwe a Asilikali / Mafakitale: Kumene kudalirika kwa kulankhulana kuli kofunika kwambiri.

Malo Ovuta (monga kutentha kwambiri ndi chinyezi): Kumene zizindikiro zosiyana zimathandiza kusunga umphumphu wa deta.

5. Malangizo Othandizira Kulumikiza Mawaya ndi Mfundo Zofunika Kuziganizira

①Chithunzi Cholumikizira Chachizolowezi:

TX+ (Kutumiza Zabwino)→RX+ (Kulandira Zabwino)

TX–(Kutumiza Zoyipa)→RX–(Kulandira Zoyipa)

RX+/RX–: Kutengera ngati gawoli likufuna mayankho, mizere iyi ingagwiritsidwe ntchito kapena ayi.

②Njira Zabwino Kwambiri:

Gwiritsani ntchito zingwe zopindika zotetezedwa kuti muwonjezere mphamvu yolimbana ndi kusokoneza.

Onetsetsani kuti chingwecho chikufanana bwino ndi kutalika kwake kuti chisawonekere bwino.

Chipangizo cholandirira chiyenera kuthandizira protocol ya RS422, kapena chosinthira cha RS422 chiyenera kugwiritsidwa ntchito.

RS422 imadziwika bwino ndi mphamvu zake zabwino kwambiri zotumizira mauthenga komanso kulimba kwake, zomwe zimapangitsa kuti ikhale yofunika kwambiri pakulankhulana kodalirika kwa ma module a laser rangefinder. Kwa ogwiritsa ntchito omwe amafuna kutumiza mauthenga akutali, kukhazikika kwa deta, komanso chitetezo champhamvu cha phokoso, kusankha module yokhala ndi chithandizo cha RS422 mosakayikira ndi ndalama yodalirika komanso yodalirika mtsogolo.
