Lits'ebetsong tsa indasteri, litebello tse hole, le lits'ebetso tsa ho lemoha ka nepo e phahameng, RS422 e hlahile e le mokhoa o tsitsitseng le o sebetsang oa puisano oa serial. E sebelisoa haholo ho li-module tsa laser rangefinder, e kopanya bokhoni ba phetisetso ea sebaka se selelele le ts'ireletso e ntle ea lerata, e etsa hore e be sehokelo sa bohlokoa lits'ebetsong tsa sejoale-joale.
1. RS422 ke eng?
RS422 (Recommended Standard 422) ke maemo a morao-rao a puisano a ntlafalitsoeng ke Electronic Industries Alliance (EIA) e hlalosang phetiso ea matšoao a fapaneng. Ho fapana le sebopeho sa setso sa RS232, RS422 e sebelisa mehala ea mats'oao e tlatselletsang ho fetisa data. Phetiso ena e fapaneng e ntlafatsa haholo ho hanyetsa lerata le ho tšepahala ha puisano.
2. Likarolo tsa Bohlokoa tsa Tekheniki tsa RS422
Mokhoa oa phetisetso: Letšoao le fapaneng (para e sothehileng)
Lebelo le Phahameng la Phetiso: 10 Mbps (mahole a makhutsoanyane)
Bohole ba Phetiso e Ntle: Ho fihla ho limithara tse 1200 (ka lebelo le tlase)
Boholo ba Node: Mokhanni a le 1 ho isa ho ba amohelang 10
Lithapo tsa Signal: Ka tloaelo lithapo tse 4 (TX+/TX-, RX+/RX-)
Noise Immunity: E phahameng (e loketse tikoloho e rarahaneng ea motlakase)
Mokhoa oa puisano: Point-to-multipoint (mokhanni a le mong ho ba amohelang ba bangata)
3. Melemo ea RS422
①Phetiso ea Bohole bo Bolelele
RS422 e ts'ehetsa phetiso ea data boholeng bo fihlang ho limithara tse 1200, e etsa hore e be e loketseng lits'ebetso moo data ea tekanyo e tlamehang ho fetisoa libakeng tse fapaneng kapa lisebelisoa.-joalo ka tlhahlobo ea literene, tlhahlobo ea perimeter, le thepa ea polokelo.
②Tšireletso e Matla ea Lerata
Ka lebaka la matšoao a eona a fapaneng, RS422 e khona ho hatella lerata le tloaelehileng, ea e etsa hore e lokele libaka tse lerata la motlakase, joalo ka limela tsa indasteri kapa lits'ebetso tsa kantle.
③Phahameng Data Botsitso
Leha ho na le lithapo tse telele tsa lithapo kapa litlhophisong tse rarahaneng tsa motlakase, RS422 e fana ka litefiso tse tlase haholo tsa tahlehelo ea data ho feta likhokahano tse tloaelehileng tsa puisano tse nang le pheletso e le 'ngoe. Sena se tiisa tlhahiso e tsitsitseng le ea nako ea sebele ea litekanyo tsa sebaka.
④Puisano e le 'ngoe ho ea ho ba bangata
RS422 e lumella moamoheli a le mong hore a buisane le ba amohelang batho ba bangata, e leng se nolofalletsang litsamaiso tse fapaneng tsa li-module tse nang le litšenyehelo tse ngata.
4. Likopo ho Laser Rangefinder Modules
RS422 e sebelisoa hangata ho li-module tsa laser rangefinder maemong a latelang:
Drones / Platforms ea Robotic: Moo lerata la tsamaiso ea ka hare le phahameng, RS422 e tiisa puisano e tsitsitseng.
Tlhokomelo ea nako e telele ea nako e telele: Moo data ea sebaka e tlamehang ho fetisoa ka botšepehi ho molaoli oa bohareng.
Litsamaiso tsa Sesole / Liindasteri: Moo botšepehi ba puisano bo leng bohlokoa haholo.
Tikoloho e thata (mohlala, mocheso o phahameng le mongobo): Moo matšoao a fapaneng a thusang ho boloka botšepehi ba data.
5. Tataiso ea Wiring le Lintlha Tse Ka sehloohong
①Setšoantšo se Tloaelehileng sa Khokahano:
TX+ (Transmitting Positive)→RX+ (Ho Fumana Ntle)
TX-(Ho fetisa hampe)→RX-(Receiving Negative)
RX+/RX-: Ho ipapisitse le hore na mojule o hloka maikutlo, mela ena e kanna ea sebelisoa kapa ea se ke ea sebelisoa.
②Mekhoa e Metle:
Sebelisa lithapo tse sothehileng tse sirelelitsoeng ho matlafatsa bokhoni ba ho thibela tšitiso.
Etsa bonnete ba hore bolelele ba thapo bo lekana le ho emisa ho qoba ho bonahatsa mats'oao.
Sesebelisoa se amohelang se tlameha ho ts'ehetsa protocol ea RS422, kapa ho lokela ho sebelisoa converter ea RS422.
RS422 e hlahella ka ts'ebetso ea eona e ntle haholo ea phetisetso le matla, e e etsa sebapali sa bohlokoa puisanong e tšepahalang ea li-module tsa laser rangefinder. Bakeng sa basebelisi ba batlang phetisetso ea nako e telele, botsitso ba data, le ts'ireletso e matla ea lerata, ho khetha mojule ka tšehetso ea RS422 ha ho pelaelo hore ke letsete le tšepahalang le le nang le bopaki ba nako e tlang.
