Mukushandiswa kwemaindasitiri, kutarisa kure, uye masisitimu ekuona zvakanyatsonaka, RS422 yave kushandiswa senzira yekutaurirana yakagadzikana uye inoshanda. Inoshandiswa zvakanyanya mumamodule e laser rangefinder, inosanganisa kugona kutumira kure kure nekudzivirira ruzha zvakanyanya, zvichiita kuti ive chinhu chakakosha mumasisitimu emazuva ano ekuranga.
1. Chii chinonzi RS422?
RS422 (Inokurudzirwa Standard 422) imhando yekutaurirana yakagadzirwa neElectronic Industries Alliance (EIA) iyo inotsanangura kutumirwa kwechiratidzo chedifferential. Kusiyana neRS232 interface yechinyakare, RS422 inoshandisa mitsara miviri yechiratidzo chinowedzera kutumira data. Kutumirwa kwechiratidzo ichi kunovandudza zvikuru kusimba kweruzha uye kuvimbika kwekutaurirana.
2. Zvinhu Zvikuru zveUnyanzvi zveRS422
Nzira yekutumira: Kusiyanisa chiratidzo (peya yakakombama)
Kumhanya Kwepamusoro Kwekutumira: 10 Mbps (padaro pfupi)
Kureba Kukuru Kwekutumira: Kusvika pamamita 1200 (nekumhanya kwakaderera)
Nhamba Yakanyanya yeMaNode: mutyairi 1 kusvika kune vanogamuchira gumi
Waya dzeChiratidzo: Kazhinji waya ina (TX+/TX)–, RX+/RX–)
Kudzivirira Ruzha: Yakakwira (yakakodzera nzvimbo dzakaoma dzemagetsi)
Modhi Yekutaurirana: Point-to-multipoint (mutyairi mumwe chete kune vanogamuchira vakawanda)
3. Mabhenefiti eRS422
①Kutakurwa Kwekure Kure
RS422 inotsigira kutapurirana kwedata padaro rinosvika 1200 metres, zvichiita kuti ive yakakodzera mashandisirwo apo data rekuyera rinofanira kutapurirwa munzvimbo dzakasiyana kana zvishandiso.—zvakaita sekuongorora njanji, kutarisa miganhu yenzvimbo, uye mafambiro enzvimbo dzekuchengetera zvinhu.
②Kusadzivirira Ruzha Rwakasimba
Nekuda kwechiratidzo chayo chekusiyanisa, RS422 inogona kudzvinyirira ruzha rwemhando yecommon-mode zvinobudirira, zvichiita kuti ive yakakodzera munzvimbo dzine ruzha rwemagetsi, senge mafekitori emaindasitiri kana kuiswa kwekunze.
③Kugadzikana Kwedata Kwakakwirira
Kunyangwe paine tambo refu dzinoshandiswa kana kuti dziri munzvimbo dzakaoma dzemagetsi, RS422 inopa mukana wakaderera wekurasikirwa nedata kupfuura nzira dzekukurukurirana dzechinyakare dzine magumo maviri. Izvi zvinoita kuti kuyerwa kwedaro kubude zvakanaka uye panguva chaiyo.
④Kutaurirana kweMunhu Mumwe Nemumwe
RS422 inobvumira host imwe chete kutaurirana nevanogamuchira vakawanda, zvichigonesa masisitimu e multi-module ranging asingadhuri.
4. Mashandisirwo muLaser Rangefinder Modules
RS422 inowanzoshandiswa mumamodule e laser rangefinder mumamiriro ezvinhu anotevera:
Mapuratifomu eDrones / Robotic: Kana ruzha rwemukati mesystem rwuri rwakanyanya, RS422 inoita kuti kutaurirana kugare kwakasimba.
Kutarisa Kureba Kwenguva: Apo data redaro rinofanira kutumirwa zvakavimbika kune central controller.
Masisitimu eMasoja / Maindasitiri: Uko kuvimbika kwekutaurirana kuri basa rakakosha.
Nzvimbo Dzakaoma (semuenzaniso, tembiricha yepamusoro uye hunyoro): Apo differential signaling inobatsira kuchengetedza data rakavimbika.
5. Gwaro reWiring uye Pfungwa Dzakakosha Dzekufunga Nadzo
①Dhayagiramu Yakajairika Yekubatanidza:
TX+ (Kutumira Zvakanaka)→RX+ (Kugamuchira Yakanaka)
TX–(Kutumira Zvakaipa)→RX–(Kugamuchira Zvakaipa)
RX+/RX–: Zvichienderana nekuti module inoda mhinduro here, mitsara iyi inogona kushandiswa kana kusashandiswa.
②Maitiro Akanakisisa:
Shandisa tambo dzakamonyoroka dzakadzivirirwa kuti uvandudze kugona kwekudzivirira kukanganiswa.
Iva nechokwadi chekuti tambo yacho yakaenzana zvakanaka uye yakavharwa zvakanaka kuti isaratidze chiratidzo.
Mudziyo unogamuchira unofanirwa kutsigira protocol yeRS422, kana kuti RS422 converter inofanira kushandiswa.
RS422 inoonekwa zvakanaka nekushanda kwayo kwakanaka uye kusimba kwayo, zvichiita kuti ive chinhu chakakosha mukukurukurirana kwakavimbika kwemamodule e laser rangefinder. Kune vashandisi vanoda kutumira kure, kugadzikana kwedata, uye kudzivirirwa kwakasimba kweruzha, kusarudza module ine rutsigiro rweRS422 pasina mubvunzo inzira yakavimbika uye inoshanda mune ramangwana.
