Intshayelelo
Njengezithuthi ezizimeleyo (ii-UGVs, iidrones, kunye neenkqubo zerobhothi) ziba yimfuneko kumashishini afana nolungiselelo, ukhuselo, kunye neziseko zophuhliso ezikrelekrele, ezikhuselekileyo nezikhuselekileyo.unxibelelwano oluthembekileyo olungenazingcingoibalulekile. Enye yezona teknoloji zinamandla eziqinisekisa ukuhanjiswa kwedatha ngaphandle kokuphazamiseka yiFrequency Hopping Spread Spectrum (FHSS).
I-FHSS bubuchule bomgangatho womkhosi obungenazingcingo obutshintsha ngokukhawuleza i-frequencies ukuphepha ukuxinana, ukunciphisa ukuphazamiseka, kunye nokugcina unxibelelwano oluzinzileyo-olwenza lube lulungele izithuthi eziphantsi komhlaba (UGVs) ezisebenza kwiindawo ezixineneyo okanye ezinobutshaba.
Kweli nqaku, siza kuhlola:
1.Isebenza njani i-FHSS kwaye kutheni iphezulu kwii-UGVs
2.Kutheni izithuthi ezingaphathwanga zifuna iFHSS?
3.Anti-jamming inkqubo wirelessiirobhothi ezizimeleyo
Yintoni iFrequency Hopping Spread Spectrum (FHSS)?
I-FHSS yindlela yokusasaza kanomathotholo apho umqondiso "uxhuma" ngokukhawuleza phakathi kweefrikhwensi ezininzi ngokulandelelana okuchazwe kwangaphambili. Ngokungafaniyo neenkqubo zesiqhelo ezisisigxina, i-FHSS ibonelela:
●I-Anti-jamming resilience-Ibalulekile kwi-UGVs yokukhusela kunye nokhuseleko
●Uthintelo lophazamiseko-Kubalulekile kwimimandla yasezidolophini okanye yemizi-mveliso enengxolo enkulu yeRF
●Amathuba aphantsi okufumanisa (LPD) - Inzuzo kwimisebenzi efihlakeleyo
Isebenza njani iFHSS
●Ubuchule bokuphindaphinda -I-transmitter kunye ne-receiver iyangqamanisa ukutshintsha amajelo ukuya kumawaka amaxesha ngesekhondi.
●Ukulandelelana kwe-pseudorandom-Ukutsibela kulandela ipateni enekhowudi, eyaziwa kuphela kwizixhobo ezigunyazisiweyo.
●Ukulungiswa kwempazamo - Ukuba i-frequency enye ivaliwe, idatha iphinda idluliselwe kwi-hop elandelayo.
Kutheni izithuthi ezingaphathwanga zifuna iFHSS?
1. Ii-UGV zomkhosi nezoKhuselo
●Ukuxhathisa i-Jamming - i-FHSS ikhusela ukuphazamiseka kwempawu kwiindawo ze-electronic warfare (EW).
●Ii-comms ezikhuselekileyo-Ukutsiba rhoqo kwenza kube nzima kakhulu ukuthintela okanye ukugqekeza idatha.
●Ukuthembeka kwebala lomlo-Kuqinisekisa ulawulo oluqhubekayo lwee-UGVs zokugada ezizimeleyo naphantsi kophazamiseko lweRF.
2. I-Automation ye-Industrial & Logistics
●Iirobhothi zeWarehouse-FHSS inqanda ukuphazamiseka kwi-Wi-Fi, iBluetooth, kunye nezinye izixhobo ezingenazingcingo.
●Iiforklift ezizimeleyo kunye nee-AGVs-Igcina imiqondiso yokukhangela ezinzileyo kwiindawo ezixineneyo zoshishino.
3. IZithuthi eziZimelayo ezisezidolophini kunye nezingekho endleleni
●Iinqwelo zedolophu ezihlakaniphile - Iiteksi eziziqhubayo kunye ne-bots yokuhambisa zixhamla kwii-V2X ezingenasiphazamiso (Imoto-kwi-Everything) ikhonkco.
●Khangela kunye nokuhlangula ii-UGVs-Isebenza ngokuthembekileyo kwiindawo zentlekele ezineziseko zoncedo ezonakeleyo.
Anti-jamming Wireless System for iiRobhothi ezizimeleyo
Imodyuli yonxibelelwano ye-FD-7800 MANET engundoqo ithatha i-Software-Defined Radio (i-SDR) i-architecture, exhasa ukulayishwa kweendlela ezahlukeneyo zamaza e-MANT. Iphawulwa nge-miniaturization kunye nokusetyenziswa kwamandla aphantsi, ixhasa i-bandwidth ephezulu ye-40MHz.
I-IWAVE wireless sytem ithatha iFrequency hopping ibonelela ngokwahlukana kwamaza kunye namandla okuchasana ne-jamming, iphucula ngokufanelekileyo umgangatho wothumelo lwekhonkco elingenazingcingo kunye nokunciphisa uphazamiseko. Nokuba ezinye iibhendi zefrikhwensi zixinene, unxibelelwano lusenokuqhubeka ngokwesiqhelo kwezinye iifrikhwensi ezingachaphazelekiyo.
Ngaphezu koko, xa kuthelekiswa nonxibelelwano lwe-frequency esisigxina, unxibelelwano lwe-FHSS lufihlakele ngakumbi kwaye kunzima ukulubamba. Ngaphandle kolwazi lwepateni yokutsiba kunye nomjikelo wokutsiba, kunzima kakhulu ukuthintela umxholo wonxibelelwano.
