Laser Kingfinder vs GPS: Kodi mungasankhe bwanji chida choyenera kwa inu?

Mu gawo laukadaulo wamakono, maudindo a laser ndi zida za GPS ndi awiri mwa zida zogwiritsidwa ntchito kwambiri. Kaya za maulendo akunja, ntchito zomanga, kapena gofu, muyeso wolondola pamtunda ndikofunikira. Komabe, ogwiritsa ntchito ambiri amakumana ndi vuto posankha ma laser a laser ndi chida cha GPS: Ndi ziti zomwe zingafunike zosowa zanga zonse? Nkhaniyi iyerekezera zonsezi kuchokera ku malingaliro olondola, malo ogwirira ntchito, ndi zosinthika zachilengedwe, komanso zochulukirapo, kukuthandizani kupanga chisankho chidziwitso.

1. Mfundo zofunika: kusiyana kwakukulu pakati pa matekinoloji awiri

Mitundu ya laser imasankha mtunda pakutulutsa mapira a laser ndikuwerengera nthawi yomwe imafunikira kuti kuwala kuti chibwerere pambuyo poyang'ana chandamale. Kulondola kwake kumatha kufikira millimeter ndi njira yabwino kwambiri, yotsimikizika mkati mwa magawo afupi (nthawi zambiri 10000 metres), kutengera mzere wosakhazikika.

GPS, kumbali inayo, imawerengera malo ogwirizira a Geographic polandila ma satellite ma saina kenako ndikuyenda mtunda wa mtunda kutengera kusintha kwa magwiridwe awa. Ubwino wake ndikuti sizikufuna kuti chitsimikizo cha chandamale chingafikire kutali ndi dziko lonse lapansi. Komabe, imakhudzidwa kwambiri ndi mphamvu yaina, nyengo, ndi zopinga monga nyumba.

2. Kufanizira kwa magwiridwe antchito

Kuyeza kulondola

Mitundu ya laser, pansi pa mikhalidwe yabwino (yopanda kusokonekera kwamphamvu, kusinkhasinkha kochokera ku ± 1 mm mpaka ± 1 masentimita, ndikuwapanga chisankho chomwe amakonda kwa minda yomangamanga ndi kapangidwe kake. Mosiyana ndi izi, kulondola kwa zida za ogula gps nthawi zambiri kumachokera ku 1 mpaka 5 metres, ndipo kumatha kukhudzidwa kwambiri ndi magawidwe satellite ndikuchedwa. Ngakhale ndi ma gps osiyanasiyana (DGPS), moyenera sichokangachotse chotchinga. Chifukwa chake, ngati mukufuna kulondola kwambiri, mtundu wa laser ndiye chisankho chabwino.

② Kusintha kwachilengedwe

Mitundu ya laser imafunikira njira yopanda chipilalacho, ndipo magwiridwe awo amatha kuwononga mikhalidwe ngati mvula, chipale chofewa, kapena kuwala kowala komwe kungafooketse mawonekedwe a laser. Zipangizo za GPS zimachita bwino m'malo otseguka, koma zimatha kutaya chizindikiro m'matawuni, ngalande, kapena nkhalango zowirira. Chifukwa chake, pazithunzi zovuta kwambiri kapena zochitika zazitali, GPS imapereka kusinthasintha kwambiri.

③ magwiridwe antchito ndi kufalitsa

Maluji a laser amagwiritsa ntchito mtunda wochepa, kutalika, ndi makona, okhala ndi mitundu yosiyanasiyana yotulutsa zinthu monga dera / voliyumu yowerengera ndi Bluetooti. Mosiyana ndi izi, zida za GPS zimathandiziranso kugwiritsa ntchito njira zoyendera, muyeso wambiri, ndikutsata mayendedwe oyenda, ndikuwapangitsa kukhala oyenera pakuyenda kunja kapena kuyenda panja kapena magalimoto. Chifukwa chake, m'magawo omwe ali ndi zofunikira zambiri, GPS imapereka phindu lokwanira.

3. Zolemba zovomerezeka

4. Kodi Mungasankhe Bwanji?

Chisankhochi chimadalira mayankho ku mafunso atatu otsatirawa:

① Kodi mukufunikira kulondola kwa millimemita?

Ngati inde, sankhani mtundu wa laser.

② Kodi muyeso wanu ndi wamkulu kuposa 1 Km?

Ngati inde, sankhani GPS kapena kuphatikiza kwa GPS ndi ma aserfinder.

③ Kodi mukuigwiritsa ntchito m'malo ovuta?

Ngati inde, GPS ndi yodalirika kwambiri, koma onetsetsani kuti chizindikirocho chimakhala chokhazikika.

Ndi kupita patsogolo kwaukadaulo, kachitidwe kophatikiza ndi kuphatikiza lidar (kupezeka kwa laser ndikuyamba kugwiritsidwa ntchito) ndi GPS zayamba kugwiritsidwa ntchito m'munda monga poyendetsa madandaulo. Zipangizozi zimatha kupeza ma commessions kudzera pa GPS pogwiritsira ntchito laser kuti mupange mitundu yolondola ya 3D, ndikupanga maubwino okwanira 3D, ndikukwaniritsa zabwino zambiri za "macroscopic poyimitsa + microscopic." Kwa ogwiritsa ntchito onse, kusankha zinthu zanzeru zomwe zimathandizira mgwirizano wa mitundu yambiri kungakhale njira yabwino kwambiri mtsogolo.

Palibe mwayi wapamwamba pakati pa ma laserfinder ndi zida za GPS. Chinsinsi chake ndikufanana ndi zosowa zanu zapakhomo. Ngati mukufuna njira yotsimikizika yochepa, yolunjika ya laser ndiye kupita. Kwa oyenda mtunda wautali kapena malo ovuta kuyika, zida za GPS ndizoyenera. Kwa ogwiritsa ntchito akatswiri, yankho losakanizidwa lomwe limaphatikiza zabwino zonse ziwiri zomwe zingakhale yankho labwino kwambiri.
