Mathata a Tloaelehileng ka li-Sensors tsa Photoelectric
Le ha li sebetsa ka mefuta-futa, li-sensor tsa photoelectric li ka ba le mathata a fapaneng a tekheniki a ka amang ts'ebetso ea tsona.A mang a mathata ana a kenyelletsa:
Mathata a kutlo
Taba e 'ngoe e tloaelehileng e hlaha ka lebaka la ho feto-fetoha ha maikutlo.Lintho tse ka ntle tse kang lerole, mongobo le ho fapana ha mocheso li ka senya bokhoni ba sensor ea ho lemoha ka nepo liphetoho tsa leseli, tse lebisang ho baleng ho sa tšepahaleng.
Mathata a ho Ikamahanya
Ho tsamaisana hantle ho bohlokoa hore li-sensor tsena li sebetse hantle.Ho se tsamaisane hantle pakeng tsa emitter le moamoheli ho ka fella ka ho bala ho sa nepahalang, ho baka tlhoko ea ho beoa ka hloko ho thibela ho se lumellane ha tšebetso.
Tšitiso ea Khanya e Ambient
Khanya e feteletseng ea tikoloho e baka tšokelo e kholo ho li-sensor tsa photoelectric.Ha leseli la ambient le feta menyako e entsoeng ke sensor, e ka hlalosa ka phoso leseli lena le eketsehileng e le lets'oao le reriloeng, e leng se bakang pherekano le liphoso tse ka bang teng.
Litšitiso Tsa Puo
Puo e fapaneng, e ts'oanang le tšitiso ea matšoao, e etsahala ha matšoao a tsoang ho sensor e le 'ngoe a kena-kenana le li-sensor tsa boahelani.Tšitiso ena e ka khopamisa ho bala, ho hlahisa ho se nepahale le ho thatafatsa ts'ebetso ea kakaretso ea marang-rang a sensor.
Mathata a Phepelo ea Matla
Litaba tse amanang le matla hangata li hlokomolohuoa empa li ka ama ts'ebetso ea sensor haholo.Phepelo e sa lekaneng ea motlakase e ka lebisa ts'ebetsong e tlase, ho totobatsa bohlokoa ba ho beha leihlo le ho boloka mohloli oa matla o tsitsitseng bakeng sa ts'ebetso e tsitsitseng ea kutlo.
Leha ho le joaloli-sensor tsa photoelectrice fana ka ts'ebetso ea bohlokoa, kutloisiso le ho sebetsana le kutloelo-bohloko, ho tsamaisana, leseli le tikolohong, puisano e fapaneng, le litaba tsa phepelo ea motlakase li bohlokoa bakeng sa ho boloka ts'epo ea tsona le ho netefatsa ho fumanoa ha data ka nepo lits'ebetsong tse fapaneng.
Mohato ka Mohato Tataiso ea Tharollo ea Mathata
Haeba sensor ea hau ea photoelectric e sa sebetse hantle, ho latela tataiso ena ea mohato ka mohato ho tla u thusa ho e lokisa.Tataiso e shebana le ho rarolla mathata a mangata a li-sensor tsa photoelectric, ho rarolla mathata a tekheniki a amanang le liphoso tsa bona tsa ts'ebetso.Sepheo ke ho hlahloba ka mokhoa o hlophisehileng le ho lokisa litaba tse ka sitisang tšebetso e nepahetseng ea kutlo.
Mohato oa 1: Hlahloba Matla
Qala ts'ebetso ea ho rarolla mathata ka ho etsa tlhahlobo ea motlakase le ea hajoale ho netefatsa hore sensor ea photoelectric e fumana matla a boletsoeng ka har'a mamello e behiloeng.Sebelisa lisebelisoa tsa ho metha ka nepo ho bala ka nepo.
Mohato oa 2: Hloekisa Likarolo Tsa ka Hare
Etsa tlhahlobo ea optical ea li-emitter tsa sensor le li-receiver.Sebelisa microscope ea boemo bo phahameng ho tseba le ho tlosa litšila tse nyenyane, ho netefatsa tsela e sa thijoang ea optical.
Mohato oa 3: Lekola ho tsamaisana
Sebelisa lisebelisoa tsa laser alignment le lisebelisoa tse nepahetseng tsa ho lekanya ho lekola le ho lokisa ho se lumellane ha angular pakeng tsa sensor ea photoelectric le li-reflector.Kenya ts'ebetsong lipalo tsa trigonometric ho etsa bonnete ba teka-tekano e nepahetseng ka har'a li-angular tolerances tse boletsoeng.
