Ha likoloi tse ikemetseng (li-UGV, li-drones, le litsamaiso tsa liroboto) li fetoha karolo ea liindasteri tse kang thepa, ts'ireletso, le meaho e bohlale, e sireletsehileng le e sireletsehileng.puisano e tšepahalang ea mohalae bohlokoa. E 'ngoe ea litheknoloji tse matla ka ho fetisisa tse netefatsang phetisetso ea data ntle le tšitiso ke Frequency Hopping Spread Spectrum (FHSS).
FHSS ke mokhoa oa ho sesa oa boemo ba sesole o fetolang maqhubu ka potlako ho qoba ho jamming, ho fokotsa tšitiso, le ho boloka likhokahano tse tsitsitseng - e leng se etsang hore e be se loketseng bakeng sa likoloi tsa fatše tse se nang batho (UGVs) tse sebetsang libakeng tse petetsaneng kapa tse tletseng bora.
Sehloohong sena, re tla hlahloba:
1.FHSS e sebetsa joang le hore na hobaneng e phahametse li-UGV
2.Ke Hobane'ng ha Likoloi Tse sa Senyeheng li Hloka FHSS?
3.Sistimi ea waelese ea anti-jammingbakeng sa liroboto tse ikemetseng
Frequency Hopping Spread Spectrum (FHSS) ke eng?
FHSS ke mokhoa oa phetisetso ea seea-le-moea moo lets'oao le "tsubehang" ka potlako lipakeng tsa maqhubu a mangata ka tatellano e boletsoeng esale pele. Ho fapana le litsamaiso tsa setso tse tsitsitseng, FHSS e fana ka:
●Anti-jamming resilience - E bohlokoa bakeng sa li-UGV tsa ts'ireletso le ts'ireletso
●Ho qoba tšitiso - E bohlokoa libakeng tsa litoropo kapa tsa indasteri tse nang le lerata le matla la RF
●Monyetla o tlase oa ho lemoha (LPD) - Molemo bakeng sa ts'ebetso ea sekhukhu
Kamoo FHSS e sebetsang kateng
●Maqhubu a matla - Mochine o fetisang molaetsa le moamoheli oa hokahanya ho chencha likanale makhetlo a likete ka motsotsoana.
●Tatelano ea Pseudorandom - Hopping e latela mokhoa o hlophisitsoeng, o tsejoang feela ka lisebelisoa tse lumelletsoeng.
●Tokiso ea phoso - Haeba leqhubu le le leng le koetsoe, data e fetisetsoa ho hop e latelang.
Ke Hobane'ng ha Likoloi Tse sa Senyeheng li Hloka FHSS?
1. Li-UGV tsa Sesole le Tšireletso
●Jamming resistance - FHSS e thibela tšitiso ea matšoao libakeng tsa ntoa ea elektroniki (EW).
●Li-comms tse bolokehileng - Ho tsubella khafetsa ho etsa hore ho be thata haholo ho thibela kapa ho senya data.
●Ho tšepahala ha lebala la ntoa - E netefatsa taolo e tsoelang pele ea li-UGV tsa paterole tse ikemetseng leha e le tlas'a tšitiso ea RF.
2. Indasteri le Logistics Automation
●Liroboto tsa polokelo - FHSS e qoba tšitiso ea Wi-Fi, Bluetooth, le lisebelisoa tse ling tse se nang mohala.
●Li-forklift tse ikemetseng le li-AGV - E boloka matšoao a tsitsitseng a ho sesa libakeng tse phetheselang tsa indasteri.
3. Likoloi tse ikemetseng tsa Urban & Off-Road
●Lifofane tsa teropo tse bohlale - Litekesi tse ikhanneng le li-delivery bots li rua molemo ho lihokelo tse se nang tšitiso tsa V2X (Vehicle-to-Everything).
●Batla le ho pholosa li-UGV - E sebetsa ka ts'epo libakeng tsa likoluoa tse nang le lisebelisoa tse senyehileng.
Anti-jamming Wireless System bakeng sa Liroboto tse ikemetseng
Mojule oa puisano oa mantlha oa FD-7800 MANET o amohela meralo ea Software-Defined Radio (SDR), e ts'ehetsang ho jarolloa ha maqhubu a fapaneng a MANET. E tšoauoa ka miniaturization le tšebeliso e tlase ea matla, e ts'ehetsa boholo ba bandwidth ea 40MHz.
IWAVE wireless sytem e sebelisa Frequency hopping e fana ka mefuta-futa ea maqhubu le matla a ho thibela ho jamming, ka katleho e ntlafatsa boleng ba phetisetso ea lihokelo tse se nang mohala le ho fokotsa tšitiso. Leha lihlopha tse ling tsa maqhubu li koaletsoe, puisano e ntse e ka tsoela pele ka mokhoa o tloaelehileng ho maqhubu a mang a sa amehang.
Ho feta moo, ha ho bapisoa le puisano ea maqhubu a tsitsitseng, puisano ea FHSS e patahane ebile e thata ho e thibela. Ntle le tsebo ea mokhoa oa ho tlolatlola le saekele ea ho tlola, ho thata haholo ho thibela litaba tsa puisano.
