Ultrasonic Distance: kev qhia, qauv xyuas

Thaum lub sij hawm tsim kho nws yog ib qho tseem ceeb kom meej ntsuas qhov kev ncua deb ntawm cov khoom. Qhov no zoo heev kev pab, ultrasonic rangefinders. Cov pab kiag li lawm yuav tau sai sai ntsuas lub cheeb tsam. Muaj ntau cov qauv yog nruab nrog ib tug nti uas yuav khaws thiab txheej txheem cov ntaub ntawv. Devices interconnected txawv nyob rau hauv kev ntsuas cov neeg thiab tej feem.

Ultrasonic Distance: Cov lus qhia rau kev siv

Yuav kom siv ib tug ntau finder mounted roj teeb, thiab tau pib, nias lub hwj huam khawm. Tom ntej no, cov neeg siv yuav tsum xaiv tus muaj nuj nqi rau cov ntaus ntawv. Yog hais tias koom, ntsuas qhov kev ncua deb, koj yuav tsum xyuam xim rau cov chav nyob. Nyob rau hauv qhov chaw ntawm lub qauv muaj cov kev xaiv kom tseg tau cov ntaub ntawv. Nyob rau hauv lub xam ntawm lub square stands lub point tseem ceeb. Mus pib dua cov ntaub ntawv hloov tawm rangefinder.

Thaum ntsuas qhov kev ncua deb ntawm cov phab ntsa tsev yuav tsum tau ntsia nruj me ntsis perpendicular mus rau qhov chaw. Thaum uas siv cov khoom no yuav tsum xyuam xim rau cov permissible ciaj ciam ntawm cov av noo thiab kub, txwv tsis pub tus ntaus ntawv tej zaum yuav tsis ua hauj lwm los yog tso saib tsis yog cov ntaub ntawv.

Yuav ua li cas yog ib qho tseem ceeb thaum xaiv ib tug

Yog hais tias kho kev ua hauj lwm yog heev npaum menyuam lub siab raug thiab compactness. Lub pom xab deb yog 20 meters. Roj teeb nyob rau hauv lub rangefinder yog feem ntau xaiv AAA series. Muaj ntau pab kiag li lawm yog tsawg heev thiab nyiaj pab ntau tshaj muaj nuj nqi. Yog li, koj yuav ceev nrooj xam cov ntaub ntawv.

Qhov kev tshuaj ntsuam yuav tsum tau kom meej meej pom. Nws yog ib nqi them sai sai mus rau lub operating tej yam kev mob. Yog li, zoo ntau yam finder muaj peev xwm ntawm kev khiav hauj lwm ntawm ib tug kub ntawm -10 ° C. Kev khiav hauj lwm av noo cov khoom yog hais txog 55%.

pheej yig rangefinders
