Kwinkqubo yokudibanisa izixhobo zeemodyuli ze-laser rangefinder, i-RS422 kunye ne-TTL zezona protocol zimbini zonxibelelwano ezisetyenziswa kakhulu. Zahluke kakhulu ekusebenzeni kothumelo kunye neemeko ezifanelekileyo. Ukukhetha iprotocol efanelekileyo kuchaphazela ngokuthe ngqo uzinzo lothumelo lwedatha kunye nokusebenza kakuhle kothumelo lwemodyuli. Zonke iimodyuli ze-rangefinder eziphantsi kweLumispot zixhasa ukulungiswa kweprotocol ezimbini. Apha ngezantsi kukho inkcazo eneenkcukacha yomahluko wazo ophambili kunye nengqiqo yokukhetha.
I. Iinkcazo eziPhambili: Umahluko obalulekileyo phakathi kweProtokholi ezimbini
● Iprotokholi ye-TTL: Iprotokholi yonxibelelwano enesiphelo esinye esebenzisa umgangatho ophezulu (5V/3.3V) ukumela "1" kunye nomgangatho ophantsi (0V) ukumela "0", idlulisela idatha ngokuthe ngqo ngomgca omnye wesignali. Imodyuli encinci ye-905nm yeLumispot inokuxhotyiswa ngeprotokholi ye-TTL, efanelekileyo kuqhagamshelo oluthe ngqo lwesixhobo esikufutshane.
● I-RS422 Protocol: Yamkela uyilo lonxibelelwano oluhlukileyo, idlulisela imiqondiso echaseneyo ngemigca emibini yesignali (imigca ye-A/B) kwaye inciphise ukuphazamiseka kusetyenziswa umahluko wesignali. Imodyuli yeLumispot ye-1535nm yomgama omde iza kumgangatho oqhelekileyo kunye ne-RS422 protocol, eyenzelwe ngokukodwa iimeko zoshishino ezikude.
II. Uthelekiso lweNtsebenzo ePhambili: Ubukhulu obu-4 beCore
● Umgama wokudlulisa: Iprotokholi ye-TTL idla ngokuba nomgama wokudlulisa we-≤10 yeemitha, efanelekileyo ekudityanisweni komgama omfutshane phakathi kweemodyuli kunye neekhompyutha ezincinci okanye ii-PLC. Iprotokholi ye-RS422 inokufikelela kumgama wokudlulisa ofikelela kwi-1200 yeemitha, ihlangabezana neemfuno zokudlulisa idatha yomgama omde zokhuseleko lomda, ukuhlolwa kwemizi-mveliso, kunye nezinye iimeko.
● Amandla Okuchasana Nokuphazamiseka: Iprotokholi ye-TTL ichaphazeleka lula kukuphazamiseka kwe-electromagnetic kunye nokulahleka kwekhebula, nto leyo eyenza ukuba ifaneleke kwiindawo zangaphakathi ezingenakuphazamiseka. Uyilo lothumelo oluhlukeneyo lwe-RS422 lubonelela ngamandla okuchasana nokuphazamiseka, olukwaziyo ukumelana nokuphazamiseka kwe-electromagnetic kwiimeko zoshishino kunye nokuncitshiswa kwesignali kwiindawo zangaphandle ezinzima.
● Indlela yoNxibelelwano lweeNtambo: I-TTL isebenzisa inkqubo yeentambo ezi-3 (i-VCC, i-GND, umgca wesignali) enocingo olulula, olufanelekileyo ekudityanisweni kwezixhobo ezincinci. I-RS422 ifuna inkqubo yeentambo ezi-4 (i-A+, i-A-, i-B+, i-B-) enocingo oluqhelekileyo, olufanelekileyo ekusetyenzisweni okuzinzileyo komgangatho wezoshishino.
● Umthamo woMthwalo: Iprotokholi ye-TTL ixhasa kuphela unxibelelwano phakathi kwesixhobo esiyintloko esinye kunye nesixhobo esiyintloko esinye. I-RS422 inokuxhasa uthungelwano lwesixhobo esiyintloko esinye kunye nezixhobo eziyintloko ezili-10, ilungelelanise neemeko zokusasazwa eziququzelelweyo zeemodyuli ezininzi.
III. Iingenelo zoLungiso lweProtocol zeeModule zeLaser zeLumispot
Zonke iimodyuli zeLumispot laser rangefinder zixhasa iiprotokholi ezimbini zeRS422/TTL ezinganyanzelekanga:
● Imeko zeShishini (Ukhuseleko lweMida, Ukuhlolwa koMbane): Imodyuli yeprotocol ye-RS422 iyacetyiswa. Xa idibene neentambo ezikhuselweyo, izinga lempazamo yebhithi yokudluliselwa kwedatha ngaphakathi kwe-1km yi-≤0.01%.
● Imifanekiso yabathengi/yomgama omfutshane (iiDrones, iiRangefinders eziphathwayo): Imodyuli yeprotocol yeTTL ikhethwa kakhulu xa kusetyenziswa amandla amancinci kwaye kulula ukuyidibanisa.
● Inkxaso yokwenza ngokwezifiso: Iinkonzo zokuguqula iprotocol ngokwezifiso kunye nokulungelelanisa ziyafumaneka ngokusekelwe kwiimfuno zomdibaniso wesixhobo sabathengi, zisusa imfuneko yeemodyuli ezongezelelweyo zokuguqula kunye nokunciphisa iindleko zokudibanisa.
IV. Ingcebiso yokukhetha: Ukuthelekisa ngokuSebenzayo ngokweMfuno
Eyona nto iphambili ekukhetheni ixhomekeke kwiimfuno ezimbini ezibalulekileyo: okokuqala, umgama wokudluliselwa (khetha i-TTL yeemitha ezili-≤10, i-RS422 yeemitha ezili-＞10); okwesibini, indawo yokusebenza (khetha i-TTL kwiindawo ezingenakuphazamiseka ngaphakathi, i-RS422 kwiindawo zoshishino nezangaphandle). Iqela lobuchwephesha leLumispot libonelela ngeengcebiso zasimahla zokulungelelanisa iprotocol ukunceda ekufezekiseni i-docking engenamthungo phakathi kweemodyuli nezixhobo ngokukhawuleza.
