Txog rau tam sim no, ultrasonic range sensors tau dhau los ua ib feem tseem ceeb ntawm lub neej niaj hnub thiab kev tsim khoom lag luam.Los ntawm cov kua theem kuaj pom, ntsuas qhov deb mus rau kev kuaj mob, daim ntawv thov teb ntawm ultrasonic nrug sensors txuas ntxiv.Kab lus no yuav muab rau koj nkag siab tob txog cov txheej txheem tsim khoom ntawm peb lub tuam txhab ultrasonic nrug sensors.
1. Lub hauv paus ntsiab lus ntawm ultrasonic range sensor
Ultrasonic ranging sensors siv cov nyhuv piezoelectric inverse ntawm piezoelectric ceramics los hloov hluav taws xob lub zog rau hauv cov kab hluav taws xob ultrasonic, thiab tom qab ntawd xam qhov kev ncua deb los ntawm kev ntsuas lub sij hawm nthuav tawm ntawm cov kab hluav taws xob hauv huab cua.Txij li thaum lub propagation ceev ntawm ultrasonic nthwv dej yog paub, qhov kev ncua deb ntawm ob yuav raug xam los ntawm tsuas yog ntsuas lub propagation lub sij hawm ntawm lub suab nthwv dej ntawm lub sensor thiab lub hom phiaj khoom.
2. Cov txheej txheem ntau lawm ntawm ultrasonic range sensors
Peb yuav qhia koj cov txheej txheem tsim khoom ntawm peb cov sensors los ntawm cov ntsiab lus hauv qab no:
❶ Kev tshuaj xyuas cov khoom nkag —— kev tshuaj xyuas cov khoom siv, cov khoom zoo yog tshuaj xyuas raws li kev soj ntsuam thoob ntiaj teb.Cov ntaub ntawv soj ntsuam feem ntau suav nrog cov khoom siv hluav taws xob (resistors, capacitors, micro-controllers, thiab lwm yam), cov khoom siv (casings, xov hlau), thiab transducers.Xyuas seb cov khoom tuaj puas tsim nyog.
❷Outsourced patching ——- Cov khoom siv hluav taws xob kuaj xyuas yog outsourced rau patching los ua PCBA, uas yog cov khoom siv ntawm lub sensor.Lub PCBA rov qab los ntawm patching kuj tseem yuav raug tshuaj xyuas, feem ntau yog kuaj xyuas cov tsos ntawm PCBA thiab seb cov khoom siv hluav taws xob xws li resistors, capacitors, thiab micro-controllers yog soldered lossis leaked.
❸Burning program ——- Ib qho tsim nyog PCBA tuaj yeem siv los hlawv qhov program rau micro-controller, uas yog software sensor.
❹ Tom qab vuam —— Tom qab qhov kev pab cuam nkag mus, lawv tuaj yeem mus rau cov kab ntau lawm rau kev tsim khoom.Feem ntau yog vuam transducers thiab xov hlau, thiab vuam Circuit Court boards nrog transducers thiab davhlau ya nyob twg nyob ntawm tej.
❺ Semi-tiav khoom sib dhos thiab kev sim —— cov modules nrog welded transducers thiab cov xov hlau yog sib sau ua ke rau hauv ib qho kev sim.Cov khoom xeem feem ntau suav nrog kev ntsuas qhov deb thiab ntsuas ncha.
❻ Potting kua nplaum —— Modules uas dhau qhov kev xeem yuav nkag mus rau cov kauj ruam tom ntej thiab siv lub tshuab ua kua nplaum rau potting.Feem ntau yog rau modules nrog kev ntsuas dej tsis haum.
❼Tam sim no cov khoom tiav ——-Tom qab lub potted module qhuav (lub sij hawm ziab yog feem ntau 4 teev), txuas ntxiv cov khoom tiav kuaj.Cov khoom kuaj tseem ceeb yog qhov ntsuas qhov deb.Yog tias qhov kev sim ua tiav, cov khoom yuav raug sau npe thiab tshuaj xyuas kom pom zoo ua ntej muab tso rau hauv qhov chaw cia.
