I-GPRS yiNkonzo yePakethe yeRadiyo Jikelele, inkonzo entsha ephuhliswe kwinkqubo ekhoyo ye-GSM, esetyenziswa ikakhulu kunxibelelwano lukanomathotholo;I-GSM sisishunqulelo somgangatho we-"GlobalSystemForMobileCommunication" (iNkqubo yoNxibelelwano lweMobile yeHlabathi) eyasungulwa ngokufanayo yiKhomishini yaseYurophu yokuMisela ngo-1992. Isebenzisa iteknoloji yonxibelelwano lwedijithali kunye nemigangatho yothungelwano olumanyeneyo ukuqinisekisa umgangatho wonxibelelwano kwaye inokuphuhlisa iinkonzo ezintsha ngakumbi kubasebenzisi. .ICandelo leKhowudi yoFikelelo oluninzi bubuchwepheshe obutsha nobuqolileyo obungenazingcingo obusekwe kubuchwepheshe obusasazekileyo;
I-61: Yintoni ukusetyenziswa kweteknoloji ye-GPRS kwizikrini zokubonisa?
Kwinethiwekhi yedatha ye-GPRS esekelwe kunxibelelwano lweselula, idatha yesiboniso sethu se-LED idluliselwa ngemodyuli ye-transceiver ye-GPRS, enokuqonda i-remote point-to-point encinci yokuhanjiswa kwedatha!Ukufezekisa injongo yolawulo olukude;
62: Yintoni unxibelelwano lweRS-232, unxibelelwano lweRS-485, kunye nonxibelelwano lweRS-422?Ziziphi iingenelo zayo nganye?
RS-232;RS-485;I-RS422 ngumgangatho wonxibelelwano lwe-serial ujongano lweekhompyuter
Igama elipheleleyo lomgangatho we-RS-232 (iprotocol) ngumgangatho we-EIA-RS-232C, apho i-EIA (i-Electronic Industry Association) imele i-American Electronic Industry Association, i-RS (umgangatho ocetyiswayo) imele umgangatho ocetyiswayo, i-232 yinombolo yesazisi, kwaye C imele uhlaziyo lwamva nje lweRS232
Ixabiso lenqanaba lomqondiso we-RS-232 interface liphezulu, ekulula ukulimaza i-chip yesekethe ye-interface.Izinga lothumelo liphantsi, kwaye umgama wothumelo ulinganiselwe, ngokubanzi ngaphakathi kwe-20M.
I-RS-485 inomgama wonxibelelwano wamashumi eemitha ukuya kumawaka eemitha.Isebenzisa ukuhanjiswa okulinganayo kunye nolwamkelo olwahlukileyo.I-RS-485 ilungele kakhulu uqhagamshelwano lwamanqaku amaninzi.
Ibhasi ye-RS422, i-RS485 kunye neesekethe ze-RS422 ziyafana ngokwesiseko.Zithunyelwa kwaye zifunyenwe kwimodi yokwahluka, kwaye azidingi ucingo lomhlaba wedijithali.Ukusebenza okungafaniyo sisizathu esisisiseko somgama omde wothumelo ngesantya esifanayo, owona mahluko osisiseko phakathi kwe-RS232 kunye ne-RS232, kuba i-RS232 iyigalelo kunye nesiphumo esisodwa, kwaye ubuncinane i-digital ground wire iyadingeka ekusebenzeni kwe-duplex.Umgca wokuthumela kunye nomgca wokufumana imigca emithathu (i-asynchronous transmission), kunye neminye imigca yokulawula inokudibaniswa ukugqiba ukuvumelanisa kunye neminye imisebenzi.
I-RS422 inokusebenza kwi-duplex epheleleyo ngaphandle kokuchaphazela enye kwenye ngeepere ezimbini zezibini ezijijekileyo, ngelixa i-RS485 inokusebenza kuphela kwisiqingatha se-duplex.Ukuthumela nokwamkela akunakwenziwa ngaxeshanye, kodwa kufuna ipere enye kuphela ejijekileyo.
I-RS422 kunye ne-RS485 inokuhambisa i-1200 yeemitha kwi-19 kpbs.Izixhobo zinokudityaniswa kumgca omtsha we-transceiver.
63: Yintoni inkqubo ye-ARM?Kwishishini le-LED, yintoni ukusetyenziswa kwayo?
I-ARM (i-Advanced RISC Machines) yinkampani ekhethekileyo ekuyilweni nasekuphuhlisweni kwee-chips ezisekelwe kwi-RISC (i-Instruction Reduced Set Computer) iteknoloji.Inokuthi ithathelwe ingqalelo njengegama lenkampani, igama eliqhelekileyo leklasi ye-microprocessors, kunye negama leteknoloji.Inkqubo yokulawula umqondiso kunye nenkqubo yokucubungula esekwe kwi-CPU enobu buchwepheshe ibizwa ngokuba yi-ARM system.Inkqubo yolawulo ekhethekileyo ye-LED eyenziwe ngetekhnoloji ye-ARM inokuqonda ulawulo lwe-asynchronous.Iindlela zonxibelelwano zinokubandakanya inethiwekhi yontanga-kwi-peer, i-LAN, i-Intanethi, kunye nonxibelelwano lwe-serial.Iqulethe phantse zonke ii-interface zePC;
64: Yintoni ujongano lwe-USB?
Isishunqulelo sesiNgesi se-USB yi-Universal Serial Bus, eguqulela kwisiTshayina njenge "Universal Serial Bus", ekwaziwa njenge Universal Serial Interface.Iyakwazi ukuxhasa iplagi eshushu kwaye inokudibanisa ukuya kwii-PC ze-127 izixhobo zangaphandle;Kukho imigangatho yojongano emibini: USB1.0 kunye ne-USB2.0
