Muaj ntau hom neeg rau, tab sis kev huv hniav zoo Ceevyog tseeb ib tug ntawm lawv. Cov tshuaj tua mos zoo yog qhov haum rau kev txuas cov siab-nrawm nrawm lossis txav chaw. Vim tias lawv cov kaum ob lub siab me me, lawv muaj cov tshuaj tiv thaiv zoo xoob tom qab xauv lossis nraub qaum.
Dab tsi yog cov xov uas tsis muaj xov ntawmNPOOV KHOV TXIV
Cov tshuaj tua mos zoo yog qhov haum rau kev txuas cov siab-nrawm nrawm lossis txav chaw. Vim yog tus me helix kaum, lawv muaj cov tshuaj tiv thaiv zoo xoob tom qab xauv lossis nraub qaum; Ib qho ntxiv, cov kaus hniav zoo yog siv rau kev kho cov tshuab sib txawv, tshwj xeeb tshaj yog rau kev ua kom nruj cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej siv
Tus hniav hniav kom zoo: Tus hniav kom zoo yog haum rau kev txuas cov siab-nrawm nrawm lossis txav chaw. Vim nws cov txiv neej helix me me, cov hniav zoo txiv ntoo muaj cov tshuaj tiv thaiv zoo xoob tom qab xauv lossis nraub qaum; Ib qho ntxiv, cov kaus hniav zoo yog siv rau kev kho cov tshuab sib txawv, tshwj xeeb tshaj yog rau kev ua kom nruj cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej ntawm cov cuab yeej siv Thaum siv cov tshuaj tua kom zoo, peb yuav tsum tsom rau kev nruj thiab lub zog los tiv thaiv kom cov neeg ceev xwm txheej thiab cov qauv kev khiav haujlwm, uas yuav ua rau tsis paub meej txog lub sijhawm thaum lub sijhawm txij nkawm. Dab tsi yog cov txiv ntoo ntawm tus hniav nplua txiv ntseej? Lub txiv ntoo muaj peev xwm muab peb nrog kev ntsuas kom hloov kho kom tsis txhob muaj kev ua haujlwm thaum siv.
Cov hau kev rau kev kuaj xyuas cov poj niam xov ntawm cov hniav dawb ceev xws li:
1. Ntsuas cov xov qub
Xov kaum, tseem hu ua cov hniav profile kaum. Qhov ntsuas ntawm xov lub kaum ntse ntse tuaj yeem ua tiav los ntawm ntsuas lub kaum sab xis, uas yog lub kaum sab xis ntawm cov xov thiab cov xov hlau ntawm cov xov axis. Tus kwv yees kwv yees ntawm cov xov kab ntawm ob sab ntawm cov kab ncaj nraim ntu ntawm xov, thiab cov ntsiab lus qhia tau raug rau qhov tsawg tshaj plaws haum.
2. Ntsuas cov suab
Suab hais txog qhov kev ncua deb ntawm qee qhov taw tes rau ntawm cov xov thiab cov lus sib haum ntawm cov xov. Kev ntsuas yuav tsum tau ua kom tiav cov xov axis.
3. Kev Ntsuas Cov Xov Ntawm Cov Pob Tawv
Lub suab seev ntawm cov xov yog qhov kev ncua deb raws lub suab li txoj kab ciav hlau percis, thiab lub suab seev taub txoj kab yog kab kev xav.

Kev Nrhiav Kom Tau
1. Cov khoom siv kho vajtse: Xov ntsuas tsis siv neeg yog raws lub teeb, duab kos duab thiab tshuaj xyuas duab, kho tshuab Nrhiav kom haum, thiab kev tswj hwm hluav taws xob.
Thaum ntsuas kev ntsuas, tom qab raug teeb meem los ntawm cov teeb pom kev zoo, cov xov uas cov xov xwm ntawm lub ntsej muag tau ntes los ntawm CCD lub koob yees duab thiab cov duab kho qhov muag. Tom qab ntawd, cov duab digital tau kis rau lub khoos phis tawm los ntawm cov duab nrhiav tau. Lub khoos phis tawj cov duab digital raws li cov lus sib piv, suav cov kev ntsuas ntawm cov xov, thiab sib piv nrog tus qauv los laij cov kev sib txawv.
2. Software System: Cov software system rau kev kuaj pom tsis siv neeg feem ntau suav nrog cov qauv tswj cov qauv, kev ua qauv duab ua qauv module, thiab lwm yam.
System Tswj Module: Kev Pib Nruab Nrab; Ua tiav qhov pib kev teeb tsa ntawm cov duab system duab interface card thiab cov qauv tsis sib xws. Cov duab manipulation; Sau thiab txuag ib qho 8- me ntsis grey duab, ntes cov duab kom nco.
Cov duab ua module: Cov duab ua module suav nrog cov duab ua ntej cov lus qhia txog kev ntsuas cov duab digital, thiab algorithms rau suav xov.
Kev Ntsuas Cov Ntsiab Lus
Kev Siv Lub Tshuab Ua Pom Siv Tshuab Siv Lub Tshuab Kev Siv Lub Tshuab Hluav Taws Xob, Tsim Kev Ntsuas Cov Lus Tsis Zoo xws li Xov Angle, Suab, thiab Suab Sib Tw Ntawm Cov Qauv Xov Xwm. Qhov ntsuas tau qhia tau tias cov xov uas tsis raug cai nyob hauv qhov yuam kev tshwj xeeb. Vim yog cov yam ntxwv zoo thiab txhim khu kev qha ntawm kev tshuaj xyuas pom, nws ntseeg tias nws tuaj yeem siv rau hauv cov kev xyaum ua khoom ntxiv tom qab kev tshawb nrhiav ntxiv.
Dab tsi yog cov xov ntawm cov xov zoo
Qhov profile ntawm cov xov ntawm ntu dhau los ntawm cov kab hlau xov yog hu ua tus hniav profile. Lub kaum sab xis ntawm cov tshuaj uas nyob ib sab uas nyob ib sab ntawm cov hniav profile kaum. Cov xov uas siv tau siv profile rau cov xov zoo tib si yog ib daim duab peb sab nrog lub kaum sab xis ntawm 60 degree.

Cia kuv piav qhia, cov uas pib nrog kuv 'yog qhov qub metric, thaum cov pib nrog'm' yog nyob rau hauv lub imperial system. Hauv cov tuam txhab hauv Suav, cov metric siv tau siv, yog li kev coj ua piv txwv, lub taub ntawm M48 yog 53 hli, uas yog qhov loj me ntawm lub laum koj xaiv.
Cov xov npib siv tau to taub raws li cov xov uas muaj kev tso cai tshaj plaws Pitch P raug xaiv thaum txoj xov dab tsi yog txiav txim siab. Piv txwv li, rau m12 xov specifications, lub suab muaj peev xwm xaiv tau los ntawm 1.75, 1.5, thiab 1. M12 × 1. Xa mus rau xov zoo. Rau cov xov ntawm cov ntxhib, tshaj tawm ntawm nws lub suab suab tuaj yeem raug rho tawm. (Txhua tus piv txwv yog Metric Xov)
