Isingeniso
Njengoba izimoto ezizimele (ama-UGV, ama-drones, nezinhlelo zamarobhothi) ziba yingxenye yezimboni ezifana nezokuthutha, ezokuvikela, nengqalasizinda ehlakaniphile, evikelekile futhiukuxhumana okungenantambo okuthembekilekubalulekile. Obunye bobuchwepheshe obuqine kakhulu obuqinisekisa ukudluliswa kwedatha okungaphazanyiswa yiFrequency Hopping Spread Spectrum (FHSS).
I-FHSS iwubuchwepheshe obungenawaya bezinga lezempi elishintsha ngokushesha amaza ukuze kugwenywe ukuminyana, ukunciphisa ukuphazamiseka, nokugcina ukuxhumana okuzinzile—okuyenza ifaneleke ezimotweni zaphansi ezingenamuntu (ama-UGV) ezisebenza ezindaweni eziminyene noma ezinobutha.
Kulesi sihloko, sizohlola:
1.Isebenza kanjani i-FHSS nokuthi kungani ingcono kuma-UGV
2.Kungani Izimoto Ezingenamuntu Zidinga i-FHSS?
3.Isistimu engenantambo ye-Anti-jammingamarobhothi azimele
Iyini iFrequency Hopping Spread Spectrum (FHSS)?
I-FHSS iyindlela yokudlulisa umsakazo lapho isiginali "igxuma" ngokushesha phakathi kwamafrikhwensi amaningi ngokulandelana okuchazwe ngaphambilini. Ngokungafani nezinhlelo zendabuko ze-fixed-frequency, i-FHSS inikeza:
●Ukuqiniswa kwe-Anti-jamming - Okubalulekile kuma-UGV okuvikela nokuvikeleka
●Ukugwema ukuphazamiseka - Kubalulekile ezindaweni zasemadolobheni noma zezimboni ezinomsindo omkhulu we-RF
●Amathuba aphansi okutholwa (i-LPD) - Inenzuzo ekusebenzeni okuyimfihlo
Isebenza kanjani i-FHSS
●I-Frequency agility - Isidlulisi kanye nomamukeli bayavumelanisa ukuze bashintshe iziteshi izikhathi eziyizinkulungwane ngomzuzwana.
●Ukulandelana kwe-pseudorandom - Ukugxuma kulandela iphethini enekhodi, eyaziwa ngamadivaysi agunyaziwe kuphela.
●Ukulungiswa kwephutha - Uma ifrikhwensi eyodwa ivinjiwe, idatha idluliselwa kabusha ku-hop elandelayo.
Kungani Izimoto Ezingenamuntu Zidinga i-FHSS?
1. Ama-UGV Ezempi Nezokuvikela
●Ukumelana ne-Jamming - I-FHSS ivimbela ukuphazamiseka kwesignali ezindaweni ze-electronic warfare (EW).
●Ama-comms avikelekile - Ukweqa imvamisa kwenza kube nzima kakhulu ukunqamula noma ukugebenga idatha.
●Ukwethenjwa kwenkundla yempi - Iqinisekisa ukulawula okuqhubekayo kwama-UGV wokugada azimele ngisho nangaphansi kokuphazanyiswa yi-RF.
2. I-Industrial & Logistics Automation
●Amarobhothi e-warehouse - I-FHSS igwema ukuphazamiseka kwe-Wi-Fi, i-Bluetooth, namanye amadivayisi angenawaya.
●Ama-forklift azenzakalelayo nama-AGV - Igcina izimpawu zokuzulazula ezizinzile ezindaweni eziminyene zezimboni.
3. Izimoto Ezizimelayo zasemadolobheni nezingekho emgwaqeni
●Imikhumbi yedolobha ehlakaniphile - Amatekisi azishayelayo nama-bots okulethwa azuza kuzixhumanisi ezingenaziphazamiso ze-V2X (Vehicle-to-Everything).
●Sesha futhi uhlenge ama-UGV - Isebenza ngokuthembekile ezindaweni zezinhlekelele ezinengqalasizinda eyonakele.
I-Anti-jamming Wireless System yamarobhothi azenzakalelayo
Imojula yezokuxhumana eyinhloko ye-FD-7800 MANET yamukela ukwakheka kwe-Software-Defined Radio (SDR), isekela ukulayishwa kwamagagasi ahlukahlukene e-MANT. Iphawuleka nge-miniaturization kanye nokusetshenziswa kwamandla aphansi, isekela umkhawulokudonsa wenkampani yenethiwekhi omkhulu ongu-40MHz.
Isistimu engenantambo ye-IWAVE isebenzisa i-Frequency hopping ihlinzeka ngokuhlukahluka kwemvamisa namandla okulwa nokujaha, ithuthukise ngempumelelo ikhwalithi yokudlulisela isixhumanisi okungenantambo kanye nokunciphisa ukuphazamiseka. Ngisho noma amanye amabhendi efrikhwensi aminyene, ukuxhumana kusengaqhubeka ngokujwayelekile kwamanye amafrikhwensi angathinteki.
Ngaphezu kwalokho, uma kuqhathaniswa nokuxhumana kwe-fixed-frequency, ukuxhumana kwe-FHSS kufihlekile futhi kunzima ukukubamba. Ngaphandle kolwazi lwephethini yokugxuma kanye nomjikelezo wokugxuma, kunzima kakhulu ukuvimba okuqukethwe kokuxhumana.
