Isesengura ry'ubwoko bwa Laser Encoding: Amahame ya tekiniki n'ikoreshwa rya Precision Repetition Frequency Code, Variable Pulse Interval Code, na PCM Code

Uko ikoranabuhanga rya laser rigenda rikwirakwira mu nzego nko gupima, itumanaho, kugenda, no kubona amakuru ari kure, uburyo bwo guhindura no gupima ibimenyetso bya laser nabwo bwarushijeho kuba butandukanye kandi bugezweho. Kugira ngo hongerwe ubushobozi bwo kurwanya ingaruka, gukoresha neza uburyo bwo gupima, no kohereza amakuru neza, abahanga mu by’ikoranabuhanga bakoze uburyo butandukanye bwo gupima, harimo Precision Repetition Frequency (PRF) Code, Variable Pulse Interval Code, na Pulse Code Modulation (PCM).

Iyi nkuru itanga isesengura ryimbitse ry’ubu bwoko busanzwe bwo gusimbuza laser kugira ngo igufashe gusobanukirwa amahame ngiro yabwo, imiterere ya tekiniki, n’imiterere y’ikoreshwa ryabwo.

1. Kode y'isubiramo ry'inshuro zikwiye (Kode ya PRF)

①Ihame rya tekiniki
Kode ya PRF ni uburyo bwo kohereza ibimenyetso by’ingufu ku murongo uhoraho (urugero: 10 kHz, 20 kHz). Muri sisitemu zo gupima imirasire ya laser, buri muvuduko ugaruka utandukaniyeho hashingiwe ku muvuduko uhamye wo gusohora, ugenzurwa cyane na sisitemu.

②Ibiranga by'ingenzi

Imiterere yoroshye n'igiciro gito cyo kuyishyira mu bikorwa

Bikwiriye gupima ahantu hagufi no ku ntego zo kugarura urumuri rwinshi

Byoroshye guhuza na sisitemu zisanzwe z'amasaha y'ikoranabuhanga

Ntibigira ingaruka nziza cyane mu bidukikije bigoye cyangwa ahantu hahurira abantu benshi bitewe n'ibyago byo"echo y'agaciro kenshi"kwivanga

③Ingero z'Ikoreshwa
Imashini zipima intera zikoresheje laser, ibikoresho byo gupima intera imwe, sisitemu zo kugenzura imikorere y'inganda

2. Kode y'igihe cyo guhindagurika kw'amagufwa (Kode y'igihe cyo guhindagurika kw'amagufwa)

①Ihame rya tekiniki
Ubu buryo bwo gukodesha bugenzura igihe hagati y’amajwi ya laser kiba gisanzwe cyangwa gikozwe mu buryo butunguranye (urugero, hakoreshejwe icyuma gitanga amakuru gikozwe mu buryo butunguranye), aho kuba gihamye. Ubu buryo butunguranye bufasha gutandukanya ibimenyetso byo kugaruka no kugabanya uburyo bwo kubangamirana mu buryo bwinshi.

②Ibiranga by'ingenzi

Ubushobozi bukomeye bwo kurwanya ingaruka, ni bwiza cyane mu gutahura intego mu bidukikije bigoye

Ikuraho neza amajwi y'abazimu

Gusobanura ibintu mu buryo buhanitse, bisaba ko habaho porosesa zikomeye cyane

Bikwiriye gukoreshwa mu gupima ahantu hatandukanye neza no kumenya ahantu hatandukanye

③Ingero z'Ikoreshwa
Sisitemu za LiDAR, sisitemu zo kugenzura umutekano wa UAV/umutekano, sisitemu zo gushakisha imbunda za gisirikare n'uburyo bwo kumenya intego

3. Guhindura Kode y'Implifier (Kode ya PCM)

①Ihame rya tekiniki
PCM ni uburyo bwo guhindura amakuru mu buryo bw'ikoranabuhanga aho ibimenyetso bya analog bipimwa, bigapimwa, kandi bigashyirwa mu buryo bwa binary. Muri sisitemu yo gutumanaho ya laser, amakuru ya PCM ashobora gutwarwa binyuze muri laser pulses kugira ngo amakuru ashyirwe mu bikorwa.

②Ibiranga by'ingenzi

Ihererekanya rihamye kandi rirwanya urusaku rwinshi

Ishobora kohereza ubwoko butandukanye bw'amakuru, harimo amajwi, amabwiriza, n'amakuru yerekeye uko ibintu bimeze

Bisaba guhuza isaha kugira ngo hamenyekane neza uburyo bwo gusesengura inyuguti ku mukiriya

Isaba ko modulators na demodulators bikora neza cyane

③Ingero z'Ikoreshwa
Ibikoresho by'itumanaho bya laser (urugero, sisitemu z'itumanaho za Free Space Optical), uburyo bwo kugenzura bwa laser kuri misile/ibyogajuru, kugarura amakuru muri sisitemu za laser telemetry

4. Umwanzuro

Nk'uko"ubwonko"muri sisitemu za laser, ikoranabuhanga ryo gukusanya amakuru hakoreshejwe laser rigena uburyo amakuru yoherezwa n'uburyo sisitemu ikora neza. Kuva ku makode y'ibanze ya PRF kugeza ku ihinduka rya PCM rigezweho, guhitamo no gushushanya gahunda zo gukusanya amakuru byabaye ingenzi mu kunoza imikorere ya sisitemu ya laser.

Guhitamo uburyo bukwiye bwo gusimbuza bisaba gusuzuma byimbitse imiterere y’ikoreshwa, urwego rw’ingaruka, umubare w’ibipimo, n’ikoreshwa ry’ingufu za sisitemu. Urugero, niba intego ari ukubaka sisitemu ya LiDAR yo gukora ibishushanyo bya 3D mu mijyi, ni byiza gukoresha kode y’intera ihindagurika ifite ubushobozi bukomeye bwo kurwanya guhagarara kw’amajwi. Ku bikoresho byoroshye byo gupima intera, kode y’impinduka ikwiye ishobora kuba ihagije.
