Gusobanukirwa byimbitse Interface ya RS422: Uburyo bwo Gutumanaho Buhamye kuri Module za Laser Rangefinder

Mu bikorwa by’inganda, mu kugenzura kure, no mu buryo bwo kumenya neza ibintu, RS422 yagaragaye nk'urwego ruhamye kandi rukora neza mu itumanaho. Ikoreshwa cyane muri module za laser rangefinder, ihuza ubushobozi bwo kohereza amakuru kure hamwe n’ubudahangarwa bwiza bw’urusaku, bigatuma iba urubuga rw’ingenzi mu buryo bugezweho bwo kohereza amakuru.

1. RS422 ni iki?

RS422 (Icyitegererezo cya 422) ni igipimo cy’itumanaho cyakozwe na Electronic Industries Alliance (EIA) gisobanura uburyo bwo kohereza ibimenyetso bitandukanye. Bitandukanye n’uburyo busanzwe bwo kohereza amakuru, RS422 ikoresha imirongo ibiri y’ibimenyetso byuzuzanya. Ubu buryo bwo kohereza amakuru butandukanye butuma habaho cyane kudakoresha urusaku no kwizerana mu itumanaho.

2. Ibiranga by'ingenzi bya tekiniki bya RS422

Uburyo bwo kohereza: Ibimenyetso bitandukanye (impande zombi)

Umuvuduko ntarengwa wo kohereza: 10 Mbps (ku ntera ngufi)

Intera yo kohereza ubutumwa ku rwego rwo hejuru: Kugeza kuri metero 1200 (ku muvuduko uri hasi)

Umubare ntarengwa w'amakuru: 1 driver kugeza kuri 10 receiver

Insinga z'ibimenyetso: Ubusanzwe insinga 4 (TX+/TX)–, RX+/RX–)

Ubudahangarwa bw'urusaku: Bufite imbaraga nyinshi (zikwiriye ibidukikije bigoye cyane bya elegitoroniki)

Uburyo bwo Gutumanaho: Aho ufatira umurongo ujya ku wundi (umushoferi umwe ujya ku bandi benshi)

3. Ibyiza bya RS422

①Kohereza ubutumwa mu ntera ndende

RS422 ifasha mu kohereza amakuru mu ntera igera kuri metero 1200, bigatuma iba nziza cyane mu bikorwa aho amakuru yo gupima agomba koherezwa ahantu hatandukanye cyangwa mu bikoresho bitandukanye.—nko gupima gari ya moshi, kugenzura imiterere y'ibice, no gutunganya ububiko.

②Ubudahangarwa bw'urusaku rukomeye

Kubera uburyo ikoresha ibimenyetso bitandukanye, RS422 ishobora gukumira urusaku rw’uburyo busanzwe, bigatuma ikoreshwa neza mu bidukikije birimo urusaku rw’amashanyarazi, nko mu nganda cyangwa mu bikorwa byo hanze.

③Guhindagurika kw'amakuru ku rwego rwo hejuru

Nubwo haba hari insinga ndende cyangwa mu buryo bugoye bw'amashanyarazi, RS422 itanga igipimo gito cyane cyo gutakaza amakuru ugereranyije n'uburyo busanzwe bwo gupima intera. Ibi bituma ibipimo by'intera bisohoka mu buryo buhamye kandi mu buryo nyabwo.

④Itumanaho ry'umuntu umwe kuri benshi

RS422 yemerera ikigo kimwe cy’itumanaho kuvugana n’ibikoresho byinshi byakira amakuru, bigatuma sisitemu zo gukusanya amakuru mu buryo buhendutse kandi buhendutse.

4. Porogaramu muri Laser Rangefinder Modules

RS422 ikunze gukoreshwa muri module za laser rangefinder mu bihe bikurikira:

Drones / Robotique Platforms: Aho urusaku rw'imbere mu mashini rubaye rwinshi, RS422 ifasha itumanaho rihamye.

Gukurikirana Intera Ndende: Aho amakuru y'intera agomba koherezwa mu buryo bwizewe ku mugenzuzi mukuru.

Sisitemu za gisirikare / inganda: Aho itumanaho ryizewe ari ingenzi cyane.

Ibidukikije bibi (urugero, ubushyuhe bwinshi n'ubushuhe): Aho ibimenyetso bitandukanye bifasha mu kubungabunga ubusugire bw'amakuru.

5. Ubuyobozi bwo gukoresha insinga n'iby'ingenzi bigomba kwitabwaho

①Ishusho isanzwe yo guhuza:

TX+ (Kohereza ubwandu bwa Positive)→RX+ (Kwakira neza)

TX–(Kohereza amakosa)→RX–(Kwakira ibyangiritse)

RX+/RX–: Bitewe nuko module isaba ibitekerezo, iyi mirongo ishobora gukoreshwa cyangwa idakoreshwa.

②Imyitozo myiza:

Koresha insinga zigoranye zikingiye kugira ngo wongere ubushobozi bwo kurwanya ingaruka mbi.

Menya neza ko uburebure bw'insinga buhuye neza kandi bugahagarara neza kugira ngo wirinde ko ikimenyetso kigaragara.

Igikoresho cyakira kigomba gushyigikira protocole ya RS422, bitabaye ibyo hagakoreshwa converter ya RS422.

RS422 iratandukanye cyane kubera ubushobozi bwayo bwo kohereza amakuru no gukomera kwayo, bigatuma iba ingenzi mu itumanaho ryizewe rya module za laser rangefinder. Ku bakoresha bakeneye kohereza amakuru kure, kudahungabana kw'amakuru, no kudakoresha urusaku rwinshi, guhitamo module ifite inkunga ya RS422 nta gushidikanya ko ari ishoramari ryizewe kandi rihamye mu gihe kizaza.
