Ho fihlela joale, li-sensor tsa ultrasonic range li fetohile karolo ea bohlokoa ea bophelo ba letsatsi le letsatsi le tlhahiso ea indasteri.Ho tloha ho ho lemoha ha boemo ba mokelikeli, tekanyo ea sebaka ho ea ho tlhahlobo ea bongaka, masimo a ts'ebeliso ea li-sensor tsa hole tsa ultrasonic a ntse a tsoela pele ho hola.Sengoliloeng sena se tla u fa kutloisiso e tebileng ea ts'ebetso ea tlhahiso ea li-sensor tsa hole tsa k'hamphani ea rona.
1. Molao-motheo oa ultrasonic rangeng sensor
Li-sensor tsa Ultrasonic tse fapaneng li sebelisa phello e fapaneng ea piezoelectric ea li-ceramics tsa piezoelectric ho fetolela matla a motlakase hore e be maballo a ultrasonic, ebe o bala sebaka ka ho lekanya nako ea phatlalatso ea maballo a ultrasonic moeeng.Kaha lebelo la ho ata ha maqhubu a ultrasonic le tsejoa, sebaka se pakeng tsa tse peli se ka baloa ka ho lekanya feela nako ea ho ata ha maqhubu a molumo pakeng tsa kutlo le ntho e lebisitsoeng.
2. Ts'ebetso ea tlhahiso ea li-sensor tse fapaneng tsa ultrasonic
Re tla u bontša ts'ebetso ea tlhahiso ea li-sensor tsa rona ho tsoa lintlheng tse latelang:
❶ Tlhahlobo ea thepa e kenang —— tlhahlobo ea thepa, boleng ba thepa bo hlahlojoa ho latela maemo a machaba a tlhahlobo. Thepa e hlahlobiloeng hangata e kenyelletsa likarolo tsa elektroniki (li-resistors, capacitor, micro-controller, jj.), likarolo tsa sebopeho (likhase, lithapo), le li-transducers.Lekola hore na lisebelisoa tse kenang li tšoaneleha.
❷Patching outsourced ——- Likaroloana tse hlahlobiloeng tsa elektroniki li fetisetsoa kantle bakeng sa ho lokisoa ho theha PCBA, e leng sesebelisoa sa sensor.PCBA e khutlile ho tloha patching e tla boela e hlahlobe, haholo-holo ho hlahloba ponahalo ea PCBA le hore na likarolo tsa elektronike tse kang resistors, capacitors, le micro-controller li rekisoa kapa li lutla.
❸Burning program ——- PCBA e tšoanelehang e ka sebelisoa ho chesa lenaneo bakeng sa micro-controller, e leng software ea sensor.
❹ Post-welding —— Ka mor’a hore lenaneo le kene, ba ka ea mocheng oa tlhahiso bakeng sa tlhahiso.Haholo-holo li-transducer le lithapo, le mapolanka a li-welding a nang le li-transducer le lithapo tsa ho qetela hammoho.
❺ Sehlahisoa se seng se felile le liteko —— limmojule tse nang le li-transducer tse cheselitsoeng le lithapo li kopanngoa hore e be e 'ngoe bakeng sa tlhahlobo.Lintho tsa tlhahlobo li kenyelletsa tlhahlobo ea sebaka le tlhahlobo ea echo.
❻ Sekhomaretsi sa pitsa —— Limojule tse fetang tekong li tla kena mohatong o latelang ’me li sebelise mochine oa sekhomaretsi bakeng sa ho etsa lipitsa.Haholo-holo bakeng sa li-module tse nang le litekanyetso tse sa keneleng metsi.
❼E qetile tlhahlobo ea lihlahisoa -—-Ka mor'a hore mochine oa pitsa o omisitsoe (nako ea ho omisa hangata ke lihora tse 4), tsoela pele ka tlhahlobo ea sehlahisoa se felileng.Ntho e ka sehloohong ea teko ke teko ea sebaka.Haeba tlhahlobo e atlehile, sehlahisoa se tla ngoloa le ho hlahlojoa hore na se shebahala joang pele se kenngoa polokelong.
