DESCRIPTION
I-RDI-54 iyunithi yesixhumi esibonakalayo ehlakaniphile exhuma okokufaka kwedijithali okuhambisanayo okungafika kwangu-54 kukhompuyutha. Ipakishwe endaweni ebiyelwe ye-NEMA4 ukuze ifakwe kude ezindaweni ezinokhahlo. Ukuxhumana nekhompuyutha yokusingatha kusetshenziswa i-EIA RS-485 half-duplex, iphrothokholi yezokuxhumana ewuchungechunge. Iphrothokholi esekelwe ku-ASCII yomyalo/yempendulo ivumela ukuxhumana cishe nanoma yiluphi uhlelo lwekhompyutha. I-RDI-54 ingenye yochungechunge lwamayunithi ahlakaniphile akude abizwa ngokuthi uchungechunge lwe-“REMOTE ACCES”. Afinyelela ku-31 REMOTE ACCES Series pods (noma amanye amadivaysi e-RS-485) angase axhunywe kukhompuyutha kunethiwekhi eyodwa ye-multidrop RS-485 enezintambo ezimbili.
I-microcontroller yohlobo lwe-8031 (ene-8Kx8 RAM, i-8Kx8 engaguquguquki EEPROM, kanye nesekhethi ye-watchdog timer) inika i-RDI-54 amandla nokuguquguquka okulindelekile kusistimu yokulawula esabalalisiwe yesimanje. Ukuze kufakwe izinhlelo ezikhethekile, i-RAM ne-EEPROM ngayinye inganwetshwa ibe ngu-32K x 8. Iyunithi iqukethe ukujikeleza kwamandla aphansi e-CMOS, isamukeli/isidlulisi esibekwe sodwa ngokubona, kanye nezimo zamandla zamandla ahlukanisiwe endawo nawangaphandle. Ingasebenza ngamanani e-baud afika ku-57.6 Kbaud ebangeni elingafika kumafithi angama-5000 ngekhebula elisontekile elicijile.
Lonke uhlelo lwe-RDI-54 liku-software esekelwe ku-ASCII futhi awekho amaswishi noma izixhumi ezizosethwa. (Okunye okuhlukile kulokhu osekushiwo ngenhla ukuthi unenketho yokudlula ama-optoisolator ngokuphinda uthole ama-jumper amathathu.) Ukusetshenziswa kwesofthiwe esekwe ku-ASCII kukuvumela ukuthi ubhale izinhlelo zokusebenza nganoma yiluphi ulimi olusezingeni eliphezulu olusekela imisebenzi yezintambo ze-ASCII futhi nawe ingasebenzisa amamojula ochungechunge lwe-REMOTE ACCES cishe nganoma iyiphi ikhompuyutha.
Imojuli, noma i-pod, ikheli liyahleleka ukusuka ku-00 kuye ku-FF hex futhi noma yiliphi ikheli elinikezwayo ligcinwa ku-EEPROM futhi lisetshenziswe njengekheli elimisiwe ku-Power-ON elandelayo. Ngokufanayo, izinga le-baud liyahleleka ku-1200, 2400, 4800, 9600, 14400, 19200, 28800, kanye no-57600 futhi ligcinwa ku-EEPROM futhi lisetshenziswe njengokuzenzakalelayo ku-Power-ON elandelayo.
Isisekelo sesikhathi, esisetshenziswa kuyo yonke imisebenzi ehlobene nesikhathi futhi siyisoftware ekhethekayo ukuhlinzeka okokufaka kwedijithaliample rates ukusuka ku-14 Hz ukuya ku-1 KHz Okokufaka kwedijithali okungafika ku-50V ampI-litude ingase ifundwe ngabanye, noma ngamabhayithi angu-8-bit. Kukhona futhi izinto zokubala zedijithali kokokufaka ngakunye. Imiphetho ekhethekayo ingabalwa kuze kufike kuzinguquko ezingu-255. Lezi zibalo zisekela Funda futhi Setha Kabusha imiyalo. Ngaphezu kwalokho, amafulegi okushintsha isimo angasethwa kunoma yimaphi amabhithi okokufaka anikwe amandla futhi angafundwa ngembobo ye-serial. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho kudingeka khona ukuthola ukuvalwa koxhumana nabo noma ukuvuleka. Leli khono lokuthola ushintsho lwesimo linikwe amandla kancane kancane kuwo wonke amabhithi okokufaka.
VIMBELA ISI-DIAGRAM
Isibali sikhathi se-watchdog esakhelwe ngaphakathi sisetha kabusha i-pod uma, ngesizathu esithile esingalindelekile, i-microcontroller "ilenga phezulu". Idatha eqoqwe yi-pod ingagcinwa ku-RAM yendawo futhi ifinyelelwe kamuva ngembobo ye-serial yekhompyutha. Lokhu kusiza imodi yokusebenza yodwa ye-pod.
SOFTWARE
JIKELELE
Uthole isofthiwe esekwe ku-ASCII ku-CD ukuze isetshenziswe ne-RDI-54. Ukuhlelwa kwe-ASCII kukuvumela ukuthi ubhale izinhlelo zokusebenza nganoma yiluphi ulimi olusezingeni eliphezulu olusekela imisebenzi yeyunithi yezinhlamvu ye-ASCII.
Iphrothokholi yokuxhumana inezinhlobo ezimbili: okukhulunywayo nokungakheli. Iphrothokholi engafakwanga ikheli ingasetshenziswa uma kusetshenziswa i-RDI-54 eyodwa kuphela. Lapho kusetshenziswa amamojula (i-pod) engaphezu kweyodwa, umthetho olandelwayo kufanele usetshenziswe. Umehluko kuphela ukuthi umyalo wekheli uthunyelwa ukunika amandla i-pod ethile. Umyalo wekheli uthunyelwa kanye kuphela phakathi nokuxhumana phakathi kwe-pod nekhompyutha yokusingatha. Inika amandla ukuxhumana naleyo pod ethize futhi ikhubaze wonke amanye ama-pod kunethiwekhi.
Ukwakheka komyalo
Konke ukuxhumana kufanele kube amabhithi edatha angu-7, ngisho nokulingana, i-stop bit engu-1. Zonke izinombolo ezithunyelwe noma ezamukelwe ku-pod zisesimweni se-hexadecimal. Izinga le-baud elizenzakalelayo lasefekthri liyi-9600 Baud. I-pod ibhekwa njengekumodi yamakheli nganoma yisiphi isikhathi lapho ikheli layo le-pod lingeyena u-00. Ikheli le-pod elizenzakalelayo lasefekthri lithi 00 (imodi okungelona ikheli).
Imodi Yekheli
Umyalo wokukhetha ikheli kufanele ukhishwe ngaphambi kwanoma yimuphi omunye umyalo ku-pod enekheli.
Umyalo wekheli umi kanje:
“!xx[CR]” lapho i-xx iyikheli le-pod elisuka ku-01 ukuya ku-FF hex, futhi i-[CR] iyi-Carriage Return, uhlamvu lwe-ASCII 13.
I-pod iphendula ngokuthi “xxN[CR]” noma “xxY[CR]” uma ushintsho lwesimo lwenzekile kumabhithi anikwe amandla kusukela ku-“Y” wokugcina noma umyalo wekheli, noma ngokuthi “xxN[CR]” uma kungenjalo.
Uma umyalo wokukhetha ikheli usukhishiwe, yonke imiyalo eyengeziwe (ngaphandle kwekheli elisha elikhethiwe) izokwenziwa yi-pod ekhethiwe. Imodi enekheli iyadingeka uma usebenzisa i-pod engaphezu kweyodwa.
Imodi Engeyona Ikheli
Uma kune-pod eyodwa kuphela exhunyiwe, awukho umyalo odingekayo wokukhetha ikheli. Ungamane ukhiphe imiyalo esohlwini lwethebula elilandelayo.
Amagama asetshenziswa kanje:
- Uhlamvu olulodwa oluncane oluthi 'x' luchaza noma iyiphi idijithi ye-hex evumelekile (0-F).
- Uhlamvu olulodwa oluncane oluthi 'b' luchaza u-'1′ noma u-'0′.
- Uhlamvu olulodwa oluncane oluthi 'p' luchaza imbobo enamabhithi ayisishiyagalombili.
- Uphawu '±' luchaza u-'+' noma u-'-'.

Ukuntuleka kwesithathu kwe-RS-232 ukuthi amadivayisi angaphezu kwamabili awakwazi ukwabelana ngekhebula elifanayo. Lokhu kuyiqiniso nange-RS-422 kodwa i-RS-485 inikeza zonke izinzuzo ze-RS-422 plus ivumela amadivayisi angafika kwangu-32 ukwabelana ngamapheya afanayo asontekile. Okuhlukile kulokhu okungenhla ukuthi amadivayisi amaningi e-RS-422 angabelana ngekhebula elilodwa uma kuzokhuluma eyodwa futhi amanye amukele wonke.
IZIMPAWU EZINGAHLUKILE ZINJANISILE
Isizathu sokuthi amadivayisi e-RS-422 kanye ne-RS-485 akwazi ukushayela imigqa emide ngokuvikeleka komsindo okwengeziwe kunamadivayisi we-RS-232 ukuthi kusetshenziswa indlela yokushayela ehlukile elinganayo. Kuhlelo lokuhlukanisa okulinganayo, i-voltage ekhiqizwa umshayeli ibonakala ngaphesheya kwezintambo. Umshayeli welayini olinganiselayo uzokhiqiza ivolumu ehlukiletage ukusuka ku-±2 ukuya ku-±6 amavolthi kuwo wonke amatheminali ayo okukhiphayo. Umshayeli welayini obhalansi angase futhi abe nesiginali ethi "vula" exhuma umshayeli kumatheminali ayo okukhiphayo. Uma “isignali yokunika amandla IVALIWE, umshayeli uyanqanyulwa entanjeni yokudlulisela. Lesi simo esinqanyuliwe noma esikhubazekile sivame ukubizwa ngokuthi yisimo se-"tristate" futhi simelela ukuvinjelwa okuphezulu. Abashayeli be-RS-485 kumele babe naleli khono lokulawula. Abashayeli be-RS-422 bangase babe nalokhu kulawula kodwa akudingekile ngaso sonke isikhathi.
Umamukeli womugqa ohlukile olinganiselayo uzwa ivolumutagisimo solayini wokudlulisela kuyo yonke imigqa yokufaka yesiginali emibili. Uma i-different input voltagu-e mkhulu kuno-+200 mV, umamukeli uzohlinzeka ngesimo esithile sokunengqondo ekuphumeni kwayo. Uma umehluko voltagi-e input ingaphansi kuka -200 mV, umamukeli uzohlinzeka ngesimo sokunengqondo esiphambene ekuphumeni kwayo. Umthamo omkhulu wokusebenzatagUbubanzi be-e busuka ku-+6V kuye ku-6V buvumela ivolumutagukuncipha okungenzeka kumakhebuli amade okudlulisa.
Ubuningi bemodi evamile voltagUkulinganisa kuka-±7V kunikeza ukuvikeleka okuhle komsindo kusuka ku-voltagifakwe emigqeni emibili esontekile. Ukuxhumana komugqa ophansi wesignali kuyadingeka ukuze kugcinwe imodi evamile voltage kulelo banga. Isekhethi ingase isebenze ngaphandle kokuxhumeka okuphansi kodwa ingase ingathembeki.

Ukuze uvimbele ukuboniswa kwesignali kukhebuli kanye nokuthuthukisa ukwenqatshwa komsindo kuyo yomibili imodi ye-RS-422 kanye ne-RS-485, isiphetho somamukeli wekhebula kufanele sinqanyulwe ngokumelana okulingana nesici sekhebuli. (Okuhlukile kulokhu kuyisimo lapho ulayini ushayelwa khona umshayeli we-RS-422 ongalokothi “unqunulwe” noma unqanyulwe emugqeni. Kulokhu, umshayeli uhlinzeka ngokuphazamiseka kwangaphakathi okuphansi okunqamula umugqa ngaleso sikhathi. )
RS-485 UKUDLULISWA KWEDATHA
I-RS-485 Standard ivumela ulayini wokudlulisela olinganiselayo ukuthi wabelane ngemodi yomugqa weqembu. Amaphesenti angaba ngu-32 abashayeli/abamukeli angabelana ngenethiwekhi yomugqa wezinhlangothi ezimbili. Izici eziningi zabashayeli nabamukeli ziyafana nakuma-RS-422 Standard. Omunye umehluko ukuthi imodi evamile voltagUmkhawulo we-e unwetshiwe futhi ungu-+12V ukuya ku-7V. Njengoba noma yimuphi umshayeli enganqanyulwa (noma aphindwe kathathu) emugqeni, kufanele amelane nale modi evamile voltage ububanzi ngenkathi isesimweni se-tristate.
Umfanekiso olandelayo ubonisa inethiwekhi evamile ye-multidrop noma yephathi. Qaphela ukuthi ulayini wokudlulisela unqanyuliwe kuzo zombili iziphetho zomugqa kodwa hhayi ezindaweni zokulahla phakathi nomugqa.
