Semotokari dzinozvimiririra (UGVs, drones, uye marobhoti masisitimu) inova yakakosha kumaindasitiri senge zvinhu, dziviriro, uye smart zvivakwa, zvakachengeteka uye.yakavimbika wireless kutauriranainokosha. Imwe yeakanyanya kusimba matekinoroji ekuona kupindira-isina kutapurirana data ndeye Frequency Hopping Spread Spectrum (FHSS).
FHSS inyanzvi yemauto-giredhi isina waya inokurumidza kushandura mafambiro kudzivirira kudhumhana, kuderedza kuvhiringwa, uye kuchengetedza yakadzikama yekubatanidza-ichiita kuti ive yakakodzera kumotokari dzepasi dzisina kurongwa (UGVs) dzinoshanda munzvimbo dzakatsvikinyidzana kana dzine hutsinye.

Chii chinonzi Frequency Hopping Spread Spectrum (FHSS)?
FHSS inzira yekuparadzira redhiyo uko chiratidzo chinokurumidza "kusvetuka" pakati peakawanda mafrequency mukutevedzana kwakatsanangurwa. Kusiyana nechinyakare fixed-frequency masisitimu, FHSS inopa:
●Anti-jamming kusimba - Yakakosha kune dziviriro uye chengetedzo UGVs
●Kupindira kudzivirira - Yakakosha munzvimbo dzemudhorobha kana maindasitiri dzine ruzha rweRF
●Mukana wakaderera wekuonekwa (LPD) - Inobatsira pakuvanda mashandiro
Iyo FHSS Inoshanda sei
●Frequency agility - Iyo dhizaini uye inogamuchira inowiriranisa kushandura chiteshi kusvika kuzviuru zvenguva pasekondi.
●Pseudorandom sequence - Hopping inoteedzera kodhi pateni, inozivikanwa chete nemidziyo ine mvumo.
●Kugadziriswa kwemhosho - Kana imwe frequency yakavharwa, data inotumirwazve pane inotevera hop.
Sei Mota Dzisina Kurongwa Dzichida FHSS?
●Jamming resistance - FHSS inodzivirira kukanganiswa kwechiratidzo muhondo yemagetsi (EW) nharaunda.
●Yakachengeteka comms - Frequency kusvetuka kunoita kuti zvinyanye kuoma kubata kana kubaya data.
●Kuvimbika kwenhandare yehondo - Inovimbisa kuenderera mberi kwekutonga kweanozvimirira patrol UGVs kunyangwe pasi pekukanganiswa kweRF.
2. Industrial & Logistics Automation
●Warehouse marobhoti - FHSS inodzivirira kukanganiswa kubva kuWi-Fi, Bluetooth, uye zvimwe zvisina waya zvishandiso.
●Autonomous forklifts & AGVs - Inochengetedza yakagadzikana masaini ekufambisa munzvimbo dzakazara maindasitiri.
3. Urban & Off-Road Autonomous Vehicles
●Smart guta zvikepe - Kuzvityaira tekisi uye kutakura mabhoti anobatsirwa kubva mukukanganisa-isina V2X (Motokari-kune-Yese) zvinongedzo.
●Kutsvaga & kununura UGVs - Inoshanda zvakavimbika munzvimbo dzenjodzi dzine dzakakuvadzwa zvivakwa.
Anti-jamming Wireless System yeAutonomous Robots
Iyo FD-7800 MANET core communication module inotora architecture yeSoftware-Defined Radio (SDR), inotsigira kurodha kweakasiyana MANET waveforms. Inoratidzwa ne miniaturization uye yakaderera simba mashandisiro, inotsigira yakakura inotakura bandwidth ye40MHz.
IWAVE isina waya sytem inotora Frequency hopping inopa frequency kusiyanisa uye anti-jamming kugona, zvinobudirira kuvandudza waya isina waya yekufambisa mhando uye kuderedza kukanganiswa. Kunyangwe mamwe ma frequency mabhendi akajairirwa, kutaurirana kunogona kuramba kuenderera kune mamwe ma frequency asina kukanganiswa.
Uyezve, zvichienzaniswa neyakagadziriswa-frequency kutaurirana, FHSS kutaurirana kwakanyanya kuvanda uye kwakaoma kubata. Pasina ruzivo rweiyo hopping pateni uye kusvetuka kutenderera, zvakanyanya kuoma kubata zvirimo zvekutaurirana.
