Mawu Oyamba
Monga magalimoto odziyimira pawokha (ma UGV, ma drones, ndi makina a robotic) amakhala ofunikira ku mafakitale monga zida, chitetezo, ndi zomangamanga zanzeru, zotetezeka komanso zotetezeka.odalirika opanda zingwe kulankhulanandizovuta. Imodzi mwamaukadaulo amphamvu kwambiri owonetsetsa kuti kufalitsa kwa data popanda kusokoneza ndi Frequency Hopping Spread Spectrum (FHSS).
FHSS ndi njira yankhondo yopanda zingwe yomwe imasintha mwachangu ma frequency kuti isagwedezeke, kuchepetsa kusokoneza, ndikusunga kulumikizana kokhazikika-kupangitsa kuti ikhale yabwino kwa magalimoto osayendetsedwa pansi (UGVs) omwe amagwira ntchito m'malo opiringizika kapena ankhanza.
M'nkhaniyi, tifufuza:
1.Momwe FHSS imagwirira ntchito komanso chifukwa chake ili yabwino kwa ma UGV
2.Chifukwa Chiyani Magalimoto Opanda Magalimoto Akufunika FHSS?
3.Anti-jamming wireless systemkwa maloboti odziyimira pawokha
Kodi Frequency Hopping Spread Spectrum (FHSS) ndi chiyani?
FHSS ndi njira yotumizira mawayilesi pomwe chizindikiro "chimadumphira" mwachangu pakati pa ma frequency angapo motsatizana. Mosiyana ndi machitidwe anthawi zonse, FHSS imapereka:
●Anti-jamming resilience - Zofunikira pachitetezo ndi chitetezo ma UGV
●Kupewa kusokoneza - Ndikofunikira m'matauni kapena mafakitale okhala ndi phokoso lalikulu la RF
●Kuthekera kocheperako (LPD) - Zopindulitsa pamachitidwe obisika
Momwe FHSS Imagwirira Ntchito
●Frequency agility - Wotumiza ndi wolandila amalumikizana kuti asinthe mayendedwe mpaka masauzande pa sekondi iliyonse.
●Kutsatizana kwa Pseudorandom - Kudumphira kumatsata ndondomeko ya coded, yomwe imadziwika ndi zipangizo zovomerezeka zokha.
●Kuwongolera zolakwika - Ngati pafupipafupi kutsekedwa, deta imatumizidwanso pa hop yotsatira.
Chifukwa Chiyani Magalimoto Opanda Magalimoto Akufunika FHSS?
1. Ma UGV Ankhondo & Chitetezo
●Kukaniza kwa Jamming - FHSS imalepheretsa kusokonezeka kwa ma sign mu madera ankhondo yamagetsi (EW).
●Ma comms otetezedwa - Kudumpha pafupipafupi kumapangitsa kuti zikhale zovuta kwambiri kuyitanitsa kapena kuthyolako deta.
●Kudalirika kwankhondo - Kumawonetsetsa kuwongolera mosalekeza kwa ma UGV oyenda okha ngakhale atasokonezedwa ndi RF.
2. Industrial & Logistics Automation
●Maloboti osungira - FHSS imapewa kusokonezedwa ndi Wi-Fi, Bluetooth, ndi zida zina zopanda zingwe.
●Ma forklift odziyimira pawokha & ma AGV - Imasunga ma siginecha okhazikika m'malo odzaza mafakitale.
3. Magalimoto Odziyimira Pawokha a M'tauni & Opanda Msewu
●Magalimoto anzeru akumzinda - Ma taxi odziyendetsa okha ndi ma bots otumizira amapindula ndi maulalo opanda zosokoneza a V2X (Galimoto-ku-Chilichonse).
●Kusaka & kupulumutsa ma UGV - Amagwira ntchito modalirika m'malo atsoka omwe ali ndi zida zowonongeka.
Anti-jamming Wireless System for Autonomous Maloboti
FD-7800 MANET core communication module imagwiritsa ntchito zomangamanga za Software-Defined Radio (SDR), zomwe zimathandizira kutsitsa ma waveform osiyanasiyana a MANET. Yodziwika ndi miniaturization komanso kugwiritsa ntchito mphamvu zochepa, imathandizira bandwidth yonyamula kwambiri ya 40MHz.
IWAVE opanda zingwe sytem imatengera Frequency hopping imapereka kusiyanasiyana kwafupipafupi komanso kuthekera kolimbana ndi jamming, kuwongolera bwino kufalikira kwa ulalo wopanda zingwe ndikuchepetsa kusokoneza. Ngakhale ma frequency ena atsekeredwa, kulumikizana kumatha kupitilizabe pafupipafupi pama frequency ena osakhudzidwa.
Kuphatikiza apo, poyerekeza ndi kulumikizana kwanthawi zonse, kulumikizana kwa FHSS kumakhala kobisika komanso kovuta kuyimitsa. Popanda kudziwa za kadumphidwe kadumphidwe ndi kadumphidwe kadumphidwe, ndizovuta kwambiri kuletsa zomwe zikuyankhulirana.
