kungakanani okwaziyo ngesithwebuli sekhodi yebha?

Iskena sekhodi yebha, esaziwa nangokuthi isifundi sekhodi yebha, isibhamu sokuskena ibhakhodi, isithwebuli sekhodi yebha, isibhamu sokuskena ibhakhodi kanye nesifundi sekhodi yebha. Kuyidivayisi yokufunda esetshenziselwa ukufunda imininingwane equkethwe kubhakhodi. Ngokusebenzisa isimiso sokubona, okuqukethwe kwekhodi yebha kukhishwa ikhodi futhi kudluliselwe kukhompuyutha noma ezinye izinto ngomugqa wedatha noma ngocingo. Isetshenziswa kakhulu ezitolo ezinkulu, i-logistics express kanye nemitapo yolwazi ukuskena amabha amakhodi ezimpahla namadokhumenti.

Abafundi bekhodi yebha abajwayelekile bavamise ukusebenzisa lobu buchwepheshe obune obulandelayo: ipeni lokukhanya, i-CCD, i-laser kanye nokukhanya okubomvu kwesithombe.

Ipeni elikhanyayo uyisifundi sokuqala sebha yokuxhumana ebanjwa ngesandla, futhi futhi iyisifundi sekhodi yebha esonga kakhulu.

Lapho sisetshenziswa, u-opharetha udinga ukuthinta ipeni lokukhanya ebusweni bekhodi yebha futhi athumele ukukhanya okuncane. thola nge-lens yepeni lokukhanya. Lapho indawo yokukhanya iwela ibhakhodi ukusuka kwesokunxele kuye kwesokudla, ukukhanya kuzobonakala engxenyeni "engenalutho" futhi kungene engxenyeni "yebha". Ngakho-ke, i-voltage eshintshashintshayo izokhiqizwa ngaphakathi kwepeni lokukhanya, ezosetshenziselwa ukuchaza amakhodi ngemva kokukhulisa nokubunjwa.

Principle of laser gun

I-Laser scanner ibiza kakhulu phakathi kwezikena ezihlukahlukene, kodwa ingakwazi hlinzeka ngezinkomba zokusebenza eziphakeme kakhulu, ngakho-ke isetshenziswa kakhulu ezimbonini ezihlukahlukene.

Isimiso esiyisisekelo sokusebenza sesithwebuli se-laser simi kanje: isithwebuli se-laser esibanjwa ngesandla sikhipha umsebe wokukhanya nge-laser diode futhi siyikhanyisela iprism ejikelezayo noma isibuko esijikayo. Ukukhanya okubonisiwe kudlula efasiteleni lokufunda futhi kukhanyise indawo yekhodi yebha. Ukukhanya kubuyela kumfundi ngemva kokuvezwa ibha noma okungenalutho, futhi kuqoqwe futhi kugxiliswe yisibuko, Kuguqulelwa kusignali kagesi nge-photoelectric converter, futhi isignali izokhishwa ngeskena noma isofthiwe yokukhipha amakhodi kutheminali.

Izikena ze-laser zihlukaniswe zaba amafomu aphethwe ngesandla nangashintshi: izibhamu ze-laser ezibanjwa ngesandla zixhumeke kalula futhi zisebenziseka kalula. Izikena ze-laser ezingaguquki zifanele izikhathi ezinokufundwa okukhulu kakhulu namakhodi amabha amancane, zikhulula izandla ngempumelelo ukuthi zisebenze.

Izinzuzo: isithwebuli se-laser singasetshenziselwa ukuskena okungathintana naye. Ngokuvamile, lapho ibanga lokufunda lidlula ama-30cm, isifundi se-laser ukuphela kokukhetha; Ikhodi yebha yokufunda ye-laser inobubanzi obuhlukahlukene bokuminyana, futhi ingafunda indawo yekhodi yebha engajwayelekile noma ngengilazi noma nge-cellophane. Ngenxa yokuthi awukufundwa ngokuthintana naye, ngeke kulimaze ilebula yekhodi yebha; Ngenxa yohlelo oluthuthuke kakhulu lokufunda nokuqopha amakhodi, izinga lokuphumelela kokuqashelwa kokufunda kokuqala liphezulu, isivinini sokuqashelwa siyashesha kunepeni lokukhanya ne-CCD, kanye nomphumela wokuqashelwa kwamabhakhodi anekhwalithi yokuphrinta empofu noma engaqondakali muhle; Izinga lephutha elincane liphansi kakhulu (cishe isigidi esisodwa kuphela kwezintathu); Isifundi se-laser sinokusebenza okuhle kwe-shockproof kanye nokuwa kobufakazi. Isibonelo, isithwebuli sochungechunge lwama-symbols4000 singawa ubufakazi ku-1.5m usimende phansi.
