Isesengura ryubwoko bwa Laser Encoding: Amahame ya tekiniki nogukoresha muburyo bwisubiramo inshuro zisanzwe, kode ihindagurika ya pulse intera, na PCM Code

Mugihe tekinoroji ya laser igenda ikwirakwira mubice nko gutandukanya, itumanaho, kugendagenda, hamwe no kurebera kure, uburyo bwo guhindura no gushushanya ibimenyetso bya laser nabyo byahindutse byinshi kandi bikomeye. Kugirango bongere ubushobozi bwo kurwanya-kwivanga, gutandukanya ukuri, no gukoresha neza amakuru, abajenjeri bakoze ubuhanga butandukanye bwo kubisobora, harimo Kode ya Precision Repetition Frequency (PRF) Code, Impinduka za Pulse Interval Code, na Pulse Code Modulation (PCM).

Iyi ngingo itanga isesengura ryimbitse ryubwoko busanzwe bwa lazeri kugirango igufashe kumva amahame yakazi yabo, ibiranga tekinike, hamwe nibisabwa.

1. Kode Yisubiramo Yumwanya Kode (PRF Code)

①Ihame rya tekiniki
Kode ya PRF nuburyo bwo kodegisi yohereza ibimenyetso bya pulse mugihe cyagenwe gisubirwamo (urugero, 10 kHz, 20 kHz). Muri sisitemu ya laser, buri garuka yagaruwe itandukanijwe hashingiwe ku nshuro zayo zanduye, igenzurwa cyane na sisitemu.

②Ibintu by'ingenzi

Imiterere yoroshye nigiciro gito cyo gushyira mubikorwa

Bikwiranye no gupima intera ngufi hamwe nintego zo hejuru-zigaragaza

Biroroshye guhuza na sisitemu gakondo ya elegitoroniki

Bidakorwa neza mubidukikije bigoye cyangwa ibintu byinshi-bigamije kubera ingaruka za“echo-agaciro-echo”kwivanga

③Gusaba
Ibikoresho bya Laser, ibikoresho byo gupima intera imwe, sisitemu yo kugenzura inganda

2.

①Ihame rya tekiniki
Ubu buryo bwa kodegisi bugenzura igihe kiri hagati ya laser pulses kugirango ibe idasanzwe cyangwa pseudo-random (urugero, ukoresheje pseudo-random generator ikurikirana), aho gukosorwa. Uku guhitamo bifasha gutandukanya ibimenyetso byo kugaruka no kugabanya kwivanga kwinshi.

②Ibintu by'ingenzi

Ubushobozi bukomeye bwo kurwanya-kwivanga, nibyiza byo kumenya intego mubidukikije bigoye

Kurwanya neza imyuka isubiramo

Kurenza decoding igoye, bisaba gutunganya cyane

Birakwiriye kurwego rwo hejuru-ruringaniza kandi rugamije kumenya byinshi

③Gusaba
Sisitemu ya LiDAR, sisitemu yo kugenzura umutekano wa UAV / umutekano, laser ya gisirikare igereranya na sisitemu yo kumenya intego

3. Guhindura Kode ya Pulse (Kode ya PCM)

①Ihame rya tekiniki
PCM ni tekinike yo guhinduranya imibare aho ibimenyetso bigereranywa byapimwe, bikabarwa, kandi bigashyirwa muburyo bubiri. Muri sisitemu yitumanaho rya laser, amakuru ya PCM arashobora gutwarwa hakoreshejwe laser pulses kugirango ugere ku makuru.

②Ibintu by'ingenzi

Ikwirakwizwa rihamye hamwe n’urusaku rukomeye

Birashoboka kohereza amakuru atandukanye, harimo amajwi, amategeko, hamwe namakuru yimiterere

Irasaba guhuza isaha kugirango urebe neza decoding kubakira

Irasaba modulator ikora cyane na demodulator

③Gusaba
Itumanaho ryitumanaho rya Laser (urugero, Sisitemu yubusa ya sisitemu yo gutumanaho yubusa), kugenzura kure ya misile / icyogajuru, gusubiza amakuru muri sisitemu ya telemeteri ya laser

4. Umwanzuro

Nka“ubwonko”ya sisitemu ya laser, tekinoroji ya laser igena uburyo amakuru atangwa nuburyo sisitemu ikora neza. Kuva kode yibanze ya PRF kugeza kuri PCM igezweho, guhitamo no gushushanya gahunda ya kodegisi byabaye urufunguzo rwo kunoza imikorere ya sisitemu.

Guhitamo uburyo bukwiye bwa kodegisi bisaba gusuzuma byimazeyo ibyasabwe, urwego rwivanga, umubare wintego, hamwe na sisitemu yo gukoresha ingufu. Kurugero, niba intego ari ukubaka sisitemu ya LiDAR yo kwerekana imiterere ya 3D yo mumijyi, impinduka ya pulse intera intera ifite ubushobozi bukomeye bwo kurwanya jamming irahitamo. Kubikoresho byoroheje byo gupima ibikoresho, kode isubiramo inshuro nyinshi kode irashobora kuba ihagije.
