Umahluko phakathi kweRS422 kunye neeProtocol zoNxibelelwano lweTTL: Isikhokelo sokuKhetha iModyuli yeLumispot yeLaser

I. Iinkcazo ezingundoqo: Umahluko obalulekileyo phakathi kweeProtokholi ezimbini
● Iprotocol ye-TTL: Iprothokholi yonxibelelwano olulodwa olusebenzisa umgangatho ophezulu (5V / 3.3V) ukumela "i-1" kunye nenqanaba eliphantsi (0V) ukumela "0", ukuhambisa idatha ngokuthe ngqo ngomgca wesignali enye. Imodyuli encinci ye-Lumispot ye-905nm inokuxhotyiswa ngeprotocol ye-TTL, ilungele uqhagamshelo oluthe ngqo lwesixhobo somgama omfutshane.
● I-RS422 Protocol: Yamkela idizayini yonxibelelwano olwahlukileyo, idlulisela imiqondiso echaseneyo ngemigca emibini yemiqondiso (imigca ye-A/B) kunye nokunciphisa ukuphazamiseka usebenzisa ukuhluka kweempawu. Imodyuli yomgama omde yeLumispot ye-1535nm iza eqhelekileyo kunye ne-RS422 protocol, eyilelwe ngokukodwa iimeko zemizi-mveliso ezikude.
II. Ukuthelekiswa koMsebenzi oPhambili: Imilinganiselo ye-4 Core
● Umgama woThutho: Iprotocol ye-TTL ngokuqhelekileyo inomgama wothumelo we-≤10 yeemitha, ezifanelekileyo ukudibanisa umgama omfutshane phakathi kweemodyuli kunye ne-single-chip microcomputers okanye ii-PLC. Iprotocol ye-RS422 inokufikelela kumgama wothumelo ukuya kuthi ga kwi-1200 yeemitha, ukuhlangabezana neemfuno zokuhanjiswa kwedatha ekude yokhuseleko lomda, ukuhlolwa kweshishini, kunye nezinye iimeko.
● I-Ability Anti-Ininterference: Iprothokholi ye-TTL isengozini yokuphazamiseka kwe-electromagnetic kunye nokulahleka kwentambo, iyenze ifanelekele indawo engaphakathi ngaphandle kokuphazamiseka. Idizayini yothumelo lolwahlulo lwe-RS422 ibonelela ngesakhono esinamandla sokuchasa uphazamiseko, esikwaziyo ukuxhathisa uphazamiseko lwe-electromagnetic kwiimeko zamashishini kunye nokuthomalalisa umqondiso kwiindawo ezintsonkothileyo zangaphandle.
● I-Wiring Method: I-TTL isebenzisa i-3-wire system (VCC, GND, umgca wesignali) kunye ne-wiring elula, efanelekileyo yokudibanisa isixhobo esincinci. I-RS422 idinga i-4-wire system (A+, A-, B+, B-) ene-wiring esemgangathweni, ilungele ukuhanjiswa okuzinzile kwe-industrial-grade.
● Umthamo womthwalo: Iprothokholi ye-TTL ixhasa kuphela unxibelelwano phakathi kwesixhobo esi-1 esiyintloko kunye nesixhobo esi-1 sekhoboka. I-RS422 inokuxhasa uthungelwano lwesixhobo esi-1 esiyintloko kunye nezixhobo ezili-10 zamakhoboka, ukuziqhelanisa neemodyuli ezininzi ezilungelelanisiweyo zokusasazwa.
III. IProtocol Adaptation Advantages kwiiModyuli zeLaser yeLumispot
Lonke uthotho lweemodyuli zeLumispot laser rangefinder zixhasa ukhetho lweRS422/TTL protocol ezimbini:
● Iimeko zoShishino (uKhuseleko lweBorder, ukuHlolwa koMbane): Imodyuli ye-RS422 yeprotocol iyacetyiswa. Xa zidityaniswe neentambo ezikhuselweyo, i-bit error rate yokudluliselwa kwedatha ngaphakathi kwe-1km yi-≤0.01%.
● Iimeko zoMthengi/uMgama oMfutshane (i-Drones, i-Handheld Rangefinders): Imodyuli yeprotocol ye-TTL ikhethwa ngokusetyenziswa kwamandla aphantsi kunye nokudibanisa lula.
● Inkxaso yokwenza ngokwezifiso: Iinkonzo zokuguqulwa kweprotocol kunye nokulungelelanisa ziyafumaneka ngokusekelwe kwiimfuno ze-interface yabathengi, ukuphelisa imfuno yeemodyuli ezongezelelweyo zokuguqulwa kunye nokunciphisa iindleko zokudibanisa.
IV. Ingcebiso yokuKhetha: Ukuhambelana okuFanelekileyo ngokweMfuno
Ingundoqo yokukhetha ixhomekeke kwiimfuno ezimbini eziphambili: okokuqala, umgama wokudlulisa (khetha i-TTL ye-≤10 yeemitha, i-RS422 ye-＞10 yeemitha); okwesibini, indawo yokusebenza (khetha i-TTL yeendawo ezingenasiphazamiso zangaphakathi, i-RS422 ye-industrial kunye neendawo zangaphandle). Iqela lobuchwephesha beLumispot libonelela simahla ngonxibelelwano lweprotocol yohlengahlengiso ukunceda ukufikelela kwi-docking engenamthungo phakathi kweemodyuli kunye nezixhobo ngokukhawuleza.
