Ukuqondwa okunzulu kwe-RS422 Interface: UKhetho loNxibelelwano oluZinzileyo kwiiModyuli zeLaser Rangefinder

Kwizicelo zemizi-mveliso, ukubeka iliso kude, kunye neenkqubo zokuvalelwa ngokuchanekileyo, i-RS422 iye yavela njengomgangatho wonxibelelwano oluzinzileyo nolusebenzayo. Isetyenziswa kakhulu kwiimodyuli ze-laser rangefinder, idibanisa amandla okuhambisa umgama omde kunye nokhuseleko lwengxolo olugqwesileyo, oko kuyenza ibe lujongano olubalulekileyo kwiinkqubo zale mihla.

1. Yintoni iRS422?

I-RS422 (uMgangatho oCetyisiweyo wama-422) ngumgangatho wonxibelelwano olulandelelanayo oluphuhliswe yi-Electronic Industries Alliance (EIA) echaza ukuhanjiswa komqondiso okwahlukileyo. Ngokungafaniyo ne-interface ye-RS232 yendabuko, i-RS422 isebenzisa iperi yemigca yesignali ehambelanayo ukuhambisa idatha. Oku kuhanjiswa kokwahluka kuphucula kakhulu ukuxhathisa ingxolo kunye nokuthembeka konxibelelwano.

2. Iimpawu eziphambili zobuGcisa zeRS422

Imo yoThutho: Umqondiso owahlukileyo (isibini esijijekileyo)

Ugqithiso lwesantya esiphezulu: 10 Mbps (kwimigama emifutshane)

Umgama woThutho oluPhezulu: Ukuya kuthi ga kwi-1200 yeemitha (ngesantya esisezantsi)

Inani eliphezulu leeNodes: 1 umqhubi ukuya 10 abamkeli

IiNcingo zoMqondiso: Ngokuqhelekileyo iingcingo ezi-4 (TX+/TX-, RX+/RX-)

Ukugonywa kwengxolo: Kuphezulu (kufanelekile kwindawo enzima ye-electromagnetic)

Imo yoNxibelelwano: I-Point-to-multipoint (umqhubi omnye kubamkeli abaninzi)

3. Izinto eziluncedo zeRS422

①Ukuhanjiswa komgama omde

I-RS422 ixhasa ukuhanjiswa kwedatha kumgama ukuya kuthi ga kwi-1200 yeemitha, iyenza ilungele usetyenziso apho idatha yokulinganisa kufuneka idluliselwe kwiindawo ezahlukeneyo okanye izixhobo.-ezifana novavanyo lukaloliwe, ukujongwa komjikelezo, kunye nolungiselelo lwendawo yokugcina impahla.

②Ukunganyangeki kweNgxolo

Enkosi kuphawu lwayo olwahlukileyo, i-RS422 inokucinezela ingxolo yendlela eqhelekileyo, iyenze ifanelekele iindawo ezinengxolo yombane, njengezityalo zoshishino okanye ufakelo lwangaphandle.

③Uzinzo lweDatha ePhakamileyo

Nokuba kukho iintambo ezinde okanye kwiisetingi zombane ezintsonkothileyo, i-RS422 ibonelela ngamaxabiso asezantsi kakhulu elahleko yedatha kunendlela yonxibelelwano oluqhelekileyo olunokuphela konxibelelwano. Oku kuqinisekisa imveliso ezinzileyo kunye nexesha langempela lokulinganisa umgama.

④Unxibelelwano omnye-kuninzi

I-RS422 ivumela umamkeli omnye ukuba anxibelelane nabamkeli abaninzi, evumela ukuba imodyuli ingabizi kakhulu kwiinkqubo ezahlukeneyo.

4. Usetyenziso kwiiModyuli zeLaser Rangefinder

I-RS422 iqhele ukusetyenziswa kwiimodyuli zoluhlu lwelaser kwezi meko zilandelayo:

Iidrones / iiPlatform zeRobhothi: Apho ingxolo yenkqubo yangaphakathi iphezulu, i-RS422 iqinisekisa unxibelelwano oluzinzileyo.

UkuJonga iPerimitha yoMgama omde: Apho idatha yomgama kufuneka ithunyelwe ngokuthembekileyo kumlawuli osembindini.

Iinkqubo zoMkhosi / zoShishino: Apho ukuthembeka konxibelelwano kubaluleke kakhulu.

Ubume beNdawo Eburhabaxa (umzekelo, ubushushu obuphezulu kunye nokufuma): Apho umqondiso wokwahluka unceda ukugcina imfezeko yedatha.

5. Isikhokelo socingo kunye neNgqwalasela ePhambili

①Umzobo woQhagamshelwano oluqhelekileyo:

TX+ (Ugqithiso oluhle)→I-RX+ (Ukufumana Kakuhle)

TX-(Ugqithiso olungalunganga)→RX-(Ukufumana okungalunganga)

RX+/RX-: Kuxhomekeke ekubeni imodyuli ifuna impendulo, le migca ingasetyenziswa okanye ingasetyenziswa.

②IiNgcebiso eziGqwesileyo:

Sebenzisa iintambo ezijijekileyo ezikhuselweyo ukukhulisa amandla okuthintela ukuphazamiseka.

Qinisekisa ubude obufanelekileyo bokuhambelana kunye nokupheliswa ukunqanda ukubonakalisa umqondiso.

Isixhobo esifumanayo kufuneka sixhase iprotocol yeRS422, okanye kufuneka kusetyenziswe isiguquli seRS422.

I-RS422 ivelele ngokusebenza kwayo okugqwesileyo kunye nokomelela, okuyenza ibe ngumdlali ophambili kunxibelelwano oluthembekileyo lweemodyuli ze-laser rangefinder. Kubasebenzisi abafuna ukuhanjiswa kwexesha elide, ukuzinza kwedatha, kunye nokunganyangeki kwengxolo enamandla, ukukhetha imodyuli enenkxaso ye-RS422 ngokungathandabuzekiyo lutyalo-mali oluthembekileyo kunye nobungqina bexesha elizayo.
