Ukuqonda Okunzulu kwe-RS422 Interface: Ukhetho Lonxibelelwano Oluzinzileyo lweeModyuli zeLaser Rangefinder

Kwizicelo zoshishino, ukujonga kude, kunye neenkqubo zokuva ngokuchanekileyo, i-RS422 ivele njengomgangatho wonxibelelwano oluzinzileyo nolusebenzayo. Isetyenziswa kakhulu kwiimodyuli ze-laser rangefinder, idibanisa amandla okudlulisa umgama omde kunye nokhuseleko olukhulu lwengxolo, nto leyo eyenza ukuba ibe yindawo ebalulekileyo kwiinkqubo zanamhlanje zokulinganisa.

1. Yintoni i-RS422?

I-RS422 (Umgangatho oNcedisiweyo we-422) ngumgangatho wonxibelelwano olulandelelanayo ophuhliswe yi-Electronic Industries Alliance (EIA) echaza ukuhanjiswa kwesignali eyahlukileyo. Ngokungafaniyo nojongano lwendabuko lwe-RS232, i-RS422 isebenzisa imigca emibini yesignali ehambelanayo ukudlulisa idatha. Olu kudluliselwa kwesignali eyahlukileyo luphucula kakhulu ukumelana nengxolo kunye nokuthembeka konxibelelwano.

2. Iimpawu zoBugcisa eziphambili ze-RS422

Imo yoThumelo: Umqondiso owahlukileyo (isibini esijijekileyo)

Isantya esiphezulu soThumelo: 10 Mbps (kwimigama emifutshane)

Umgama ophezulu woThumelo: Ukuya kuthi ga kwiimitha ezili-1200 (ngesantya esiphantsi)

Inani eliphezulu leeNode: umqhubi omnye ukuya kwabamkeli abali-10

Iintambo zeSignali: Ngokwesiqhelo iintambo ezi-4 (TX+/TX)–, RX+/RX–)

Ukungakhuseleki kwingxolo: Iphezulu (ifanelekile kwiindawo ezintsonkothileyo ze-electromagnetic)

Indlela yoNxibelelwano: I-Point-to-multipoint (umqhubi omnye ukuya kwi-receivers ezininzi)

3. Iingenelo ze-RS422

①Uthumelo lomgama omde

I-RS422 ixhasa ukuhanjiswa kwedatha kumgama ofikelela kwi-1200 yeemitha, nto leyo eyenza ukuba ilungele usetyenziso apho idatha yokulinganisa kufuneka idluliselwe kwiindawo ezahlukeneyo okanye kwizixhobo ezahlukeneyo.—njengokuhlola uloliwe, ukujonga umda, kunye nokuhanjiswa kwezinto zokugcina impahla.

②Ukungakhuseleki kwingxolo enamandla

Ngenxa yesignali yayo eyahlukileyo, i-RS422 inokuyicinezela ngempumelelo ingxolo yendlela eqhelekileyo, nto leyo eyenza ifaneleke kwiindawo ezinengxolo yombane, njengezityalo zoshishino okanye ukufakelwa kwangaphandle.

③Uzinzo lweDatha oluPhezulu

Nokuba kukho intambo ende okanye kwiindawo ezintsonkothileyo zombane, i-RS422 inika amazinga okulahleka kwedatha aphantsi kakhulu kuneendlela zonxibelelwano zemveli eziphelayo. Oku kuqinisekisa ukuba umlinganiselo womgama uphuma ngendlela ezinzileyo neyangempela.

④Unxibelelwano oluvela kumntu omnye ukuya komnye

I-RS422 ivumela i-host enye ukuba inxibelelane nee-receivers ezininzi, nto leyo evumela iinkqubo zokusasaza iimodyuli ezininzi ezingabizi kakhulu.

4. Usetyenziso kwiimodyuli zeLaser Rangefinder

I-RS422 isetyenziswa kakhulu kwiimodyuli ze-laser rangefinder kwiimeko ezilandelayo:

Iidrone / Iiplatfomu zeRobotic: Apho ingxolo yangaphakathi yenkqubo iphezulu, i-RS422 iqinisekisa unxibelelwano oluzinzileyo.

Ukubeka esweni i-Long-Range Perimeter: Apho idatha yomgama kufuneka idluliselwe ngokuthembekileyo kumlawuli ophakathi.

Iinkqubo zoMkhosi/zoShishino: Apho ukuthembeka konxibelelwano kubaluleke kakhulu khona.

Iindawo ezinobungozi (umz., ubushushu obuphezulu kunye nokufuma): Apho imiqondiso eyahlukileyo inceda ukugcina ukuthembeka kwedatha.

5. Isikhokelo soNxibelelwano lweeNtambo kunye nezinto ezibalulekileyo ekufuneka uziqwalasele

①Umzobo oQhelekileyo woQhagamshelo:

TX+ (Ukudlulisa i-positive)→I-RX+ (Ukufumana i-Positive)

TX–(Ukudlulisa okungekuhle)→RX–(Ukufumana okungalunganga)

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

②Iindlela ezilungileyo zokwenza izinto:

Sebenzisa iintambo ezijijekileyo ezikhuselweyo ukuphucula amandla okulwa nokuphazamiseka.

Qinisekisa ukuba ubude bentambo buhambelana kwaye buphela ngokufanelekileyo ukuze uphephe ukubonakaliswa kwesiginali.

Isixhobo esamkelayo kufuneka sixhase iprotocol ye-RS422, okanye kufuneka kusetyenziswe i-RS422 converter.

I-RS422 ibalasele ngokusebenza kwayo okugqwesileyo kokudlulisa kunye nokuqina kwayo, nto leyo eyenza ukuba ibe ngumdlali ophambili kunxibelelwano oluthembekileyo lweemodyuli ze-laser rangefinder. Kubasebenzisi abafuna ukudlulisa idatha ekude, uzinzo lwedatha, kunye nokhuseleko oluqinileyo lwengxolo, ukukhetha imodyuli enenkxaso ye-RS422 ngokuqinisekileyo lutyalo-mali oluthembekileyo nolunokuqinisekiswa kwixesha elizayo.
