Umehluko Phakathi kwe-RS422 kanye ne-TTL Communication Protocols: Lumispot Laser Selection Guide Module

I. Izincazelo Eziwumgogodla: Umehluko Obalulekile Phakathi Kwamaphrothokholi Amabili
● Iphrothokholi ye-TTL: Iphrothokholi yokuxhumana enomkhawulo owodwa esebenzisa izinga eliphezulu (5V/3.3V) ukuze imele u-"1" nezinga eliphansi (0V) ukuze imele u-"0", idlulisela idatha ngokuqondile ngomugqa wesiginali eyodwa. Imojula encane ye-Lumispot engu-905nm ingahlonyiswa ngephrothokholi ye-TTL, ifanele ukuxhumana okuqondile kwedivayisi yebanga elifushane.
● Iphrothokholi ye-RS422: Yamukela idizayini yokuxhumana ehlukile, idlulisa amasignali aphikisanayo ngemigqa yesiginali emibili (imigqa A/B) kanye nokususa ukuphazamiseka kusetshenziswa umehluko wesignali. Imojula yebanga elide ye-Lumispot ye-1535nm iza ejwayelekile nephrothokholi ye-RS422, eklanyelwe ngokukhethekile izimo zezimboni zamabanga amade.
II. Ukuqhathanisa Ukusebenza Okubalulekile: Izilinganiso Ezingu-4 Eziyinhloko
● Ibanga Lokudlulisela: Iphrothokholi ye-TTL ngokuvamile inebanga lokudlulisela elingamamitha angu-≤10, elifanele ukuhlanganiswa kwebanga elifushane phakathi kwamamojula namakhompiyutha e-single-chip noma ama-PLC. Iphrothokholi ye-RS422 ingafinyelela ibanga lokudlulisela elingafika kumamitha ayi-1200, ihlangabezane nezidingo zokudluliselwa kwedatha ekude zokuvikela emngceleni, ukuhlolwa kwezimboni, nezinye izimo.
● Ikhono Lokumelana Nokuphazamiseka: Iphrothokholi ye-TTL isengozini yokuphazanyiswa nguzibuthe kagesi nokulahlekelwa ikhebula, okuyenza ifanelekele izindawo zasendlini ezingenaziphazamiso. Idizayini yokudlulisela ehlukile ye-RS422 inikeza ikhono eliqinile lokulwa nokuphazamiseka, elikwazi ukumelana nokuphazamiseka kazibuthe ezimeni zezimboni kanye nokuncishiswa kwesignali ezindaweni eziyinkimbinkimbi zangaphandle.
● Indlela Yokufaka Izintambo: I-TTL isebenzisa isistimu yezintambo ezingu-3 (VCC, GND, umugqa wesiginali) enezintambo ezilula, ezifanele ukuhlanganiswa kwedivayisi encane. I-RS422 idinga isistimu yezintambo ezingu-4 (A+, A-, B+, B-) enezintambo ezijwayelekile, ezilungele ukusetshenziswa okuzinzile kwezinga lezimboni.
● Umthamo Wokulayisha: Iphrothokholi ye-TTL isekela kuphela ukuxhumana phakathi kwedivayisi eyinhloko engu-1 kanye nesigqila esi-1. I-RS422 ingasekela ukuxhumana kwenethiwekhi yedivayisi eyinhloko engu-1 kanye namadivayisi ezinceku eziyi-10, ivumelane nezimo zokuthunyelwa okudidiyelwe kwamamojula amaningi.
III. I-Protocol Adaptation Izinzuzo zamamojula we-Lumispot Laser
Lonke uchungechunge lwamamojula we-Lumispot laser rangefinder lusekela izivumelwano ezimbaxambili ze-RS422/TTL:
● Izimo Zezimboni (Ukuphepha Kwemingcele, Ukuhlola Amandla): Imojula yephrothokholi ye-RS422 iyanconywa. Uma ibhangqwe nezintambo ezivikelekile, izinga lephutha elincane lokudluliswa kwedatha phakathi kwe-1km ngu-≤0.01%.
● Izimo zabathengi/zebanga elifushane (I-Drones, I-Handheld Rangefinders): Imojula yephrothokholi ye-TTL ikhethwa ngokusetshenziswa kwamandla okuphansi nokuhlanganiswa okulula.
● Ukusekelwa Kokwenza Ngokwezifiso: Izinsizakalo zokuguqulwa kwephrothokholi ngokwezifiso kanye nezimo ziyatholakala ngokusekelwe ezidingweni zokusebenzelana kwedivayisi yamakhasimende, okuqeda isidingo samamojula okuguqulwa engeziwe nokunciphisa izindleko zokuhlanganisa.
IV. Isiphakamiso Sokukhetha: Ukufanisa Okusebenzayo Ngokufunwa
Umnyombo wokukhetha ulele ezidingweni ezimbili ezibalulekile: okokuqala, ibanga lokudlulisela (khetha i-TTL yamamitha angu-≤10, i-RS422 engu-＞10 wamamitha); okwesibili, indawo yokusebenza (khetha i-TTL yendawo engenaziphazamiso zasendlini, i-RS422 yezilungiselelo zezimboni nezangaphandle). Ithimba lezobuchwepheshe le-Lumispot lihlinzeka ngokubonisana kwamahhala kokujwayelana nephrothokholi ukuze lisize ukufeza ukutholakala kwemikhumbi okungenamthungo phakathi kwamamojula nezinto zokusebenza ngokushesha.
