Raws li kev tsav tsheb tsis muaj zog (UGVs, drones, thiab robotic systems) ua ib qho tseem ceeb rau kev lag luam xws li kev thauj mus los, kev tiv thaiv, thiab cov khoom siv ntse, ruaj ntseg thiabtxhim khu kev qha wireless kev sib txuas lusyog qhov tseem ceeb. Ib qho ntawm cov thev naus laus zis uas muaj zog tshaj plaws kom ntseeg tau tias tsis muaj kev cuam tshuam cov ntaub ntawv xa mus yog Frequency Hopping Spread Spectrum (FHSS).
FHSS yog cov txheej txheem kev ua tub rog-qib wireless uas hloov pauv ceev ceev kom tsis txhob muaj kev cuam tshuam, txo kev cuam tshuam, thiab tswj kev sib txuas ruaj khov-ua rau nws zoo tagnrho rau cov tsheb tsis muaj neeg tsav tsheb (UGVs) ua haujlwm hauv qhov chaw tsis muaj neeg coob lossis muaj kev sib ntxub.
Hauv kab lus no, peb yuav tshawb nrhiav:
1.FHSS ua haujlwm li cas thiab vim li cas nws zoo dua rau UGVs
2.Vim li cas Unmanned Tsheb Yuav Tsum FHSS?

Frequency Hopping Spread Spectrum (FHSS) yog dab tsi?
FHSS yog ib txoj kev xa xov tooj cua uas lub teeb liab "hops" sai heev ntawm ntau zaus nyob rau hauv ib theem ua ntej. Tsis zoo li cov kab ke ruaj khov, FHSS muab:
●Anti-jamming resilience - Qhov tseem ceeb rau kev tiv thaiv thiab kev ruaj ntseg UGVs
●Kev zam kev cuam tshuam - Qhov tseem ceeb hauv nroog lossis thaj chaw muaj kev lag luam nrog lub suab nrov RF hnyav
●Tsawg qhov tshwm sim ntawm kev kuaj pom (LPD) - Muaj txiaj ntsig zoo rau kev ua haujlwm zais cia
FHSS ua haujlwm li cas
●Zaus agility - Lub transmitter thiab receiver synchronize hloov raws li ntau txhiab zaus ib ob.
●Pseudorandom sequence - Hopping ua raws li tus qauv coded, paub tsuas yog rau cov khoom siv tau tso cai.
●Kev kho qhov yuam kev - Yog tias ib qho zaus raug thaiv, cov ntaub ntawv raug xa rov qab rau ntawm lub hop tom ntej.
Vim li cas Unmanned Tsheb Yuav Tsum FHSS?
●Jamming tsis kam - FHSS tiv thaiv teeb meem cuam tshuam hauv hluav taws xob ua tsov rog (EW) ib puag ncig.
●Kev ruaj ntseg comms - Ntau zaus hopping ua rau nws nyuaj heev los cuam tshuam lossis hack cov ntaub ntawv.
●Battlefield kev cia siab - Ua kom muaj kev tswj xyuas tas li ntawm kev tswj hwm tus kheej UGVs txawm nyob hauv RF cuam tshuam.
2. Muaj & Logistics Automation
●Warehouse robots - FHSS zam kev cuam tshuam los ntawm Wi-Fi, Bluetooth, thiab lwm yam khoom siv wireless.
●Autonomous forklifts & AGVs - Khaws cov cim taw qhia ruaj khov hauv thaj chaw muaj neeg coob.
3. Nroog & Off-Road Autonomous Tsheb
●Smart nroog fleets - Tsav tsheb tavxij tus kheej thiab xa cov bots tau txais txiaj ntsig los ntawm kev cuam tshuam tsis pub muaj V2X (Lub Tsheb-rau-Txhua Yam) txuas.
●Tshawb nrhiav & cawm UGVs - Ua haujlwm ntseeg tau hauv thaj chaw muaj kev puas tsuaj nrog kev puas tsuaj.
Anti-jamming Wireless System rau Autonomous Robots
FD-7800 MANET core kev sib txuas lus module txais yuav Software-Defined Radio (SDR) architecture, txhawb kev thauj khoom ntawm ntau yam MANET waveforms. Tus cwj pwm los ntawm kev siv hluav taws xob tsawg thiab kev siv hluav taws xob tsawg, nws txhawb nqa qhov siab tshaj plaws bandwidth ntawm 40MHz.
IWAVE wireless sytem txais zaus hopping muab ntau qhov sib txawv thiab muaj peev xwm los tiv thaiv kev sib tw, txhim kho kev sib txuas wireless zoo thiab txo kev cuam tshuam. Txawm hais tias qee qhov zaus band raug kaw, kev sib txuas lus tseem tuaj yeem ua tau ib txwm ua rau lwm qhov tsis cuam tshuam.
Ntxiv mus, piv rau kev sib txuas lus ruaj khov, FHSS kev sib txuas lus yog qhov zais thiab nyuaj rau cuam tshuam. Yog tsis muaj kev paub txog tus qauv hopping thiab hopping voj voog, nws yog qhov nyuaj heev los cuam tshuam cov ntsiab lus ntawm kev sib txuas lus.
