Inzwa ye-retro-reflective ene-polarized reflector ihlinzekwa ngento ebizwa ngokuthi i-polarization filter. Lesi sihlungi senza isiqiniseko sokuthi ukukhanya okunobude obuthile obuthile kuyaboniswa futhi wonke amanye amaza awabonakali. Ngokusebenzisa lesi sibaluli, ukukhanya okunobude beza okukhanya okukhishiwe kuphela okuboniswayo.
Umgomo wokusebenza kwenzwa ye-Photoelectric
Ukusebenza okuyisisekelo Kwenzwa ye-Photoelectric ukuthi, inzwa ithumela ukukhanya okuvela engxenyeni yenzwa ebizwa ngokuthi i-emitter, futhi le nsimbi yokukhanya ihambela engxenyeni yenzwa eqoqa ukukhanya okubizwa ngokuthi umamukeli. Izinhlobo ezahlukene zalezi zinzwa zibamba i-beam yokukhanya ngezindlela ezihlukahlukene. Kungakhathalekile ukuthi iluphi uhlobo lwenzwa, isebenza njengenzwa yokushintsha isithombe kagesi.
Izinhlobo zezinzwa ze-photoelectric
Inzwa ye-photoelectric nge-beam
Okokuqala, sizokhuluma ngohlobo lwe-Brough-Beam Photoelectric Sensor. Izinzwa ze-Brough-Beam zine-emitter nomamukeli engxenyeni yazo ehlukene.
Ukuze inzwa ye-Breat-Beam isebenze, isithumeli nomamukeli kufanele sikhonjwe ngaso sodwa futhi siqondaniswe.
Uma ziqondanisiwe futhi kungekho lutho oluvimba ukukhanya, okukhiphayo kwenzwa kuzokhanya.
Uma ufaka okuthile phakathi kwe-emitter nomamukeli ukuze uvimbele ukukhanya, okukhiphayo kwenzwa kuzocisha.
Isignali yokuphuma kwenzwa
Okuphumayo kwenzwa yisignali esuka kunzwa iye ku-PLC. Khumbula, isebenza njengenzwa yokushintsha isithombe kagesi, iqedela umjikelezo lapho yenziwe yasebenza. Kuye ngenzwa, okukhiphayo kungaba isignali enhle noma isignali engalungile.
Uhlobo lwesignali yokuphuma kwenzwa ozoyisebenzisa incike ekutheni inzwa ixhumeke kuluphi uhlobo lwekhadi lokufaka le-PLC.
Ngokwesibonelo,
– Uma inzwaI-PNP, okusho ukuthi inesignali ephumayo enhle, intambo yokuphuma kwenzwa kuzodingeka ixhunywe ku-aecwilaikhadi lokufaka.
– Uma inzwaI-NPNisignali yokuphumayo inegethivu futhi intambo yokuphumayo izodinga ukuxhunywa ku-aukutholaikhadi lokufaka.
Isifinyezo
Ekubuyekezeni, ngokufunda lesi sihloko ufunde mayelana nezinhlobo ezintathu eziyisisekelo zezinzwa ze-Photoelectric:
- Nge-Beam,
- I-Retroreflective,
– Kusatshalaliswe.
Ufunde ukuthi zontathu izinzwa zisebenzisa ukukhanya ukuthola izinto futhi zontathu izinzwa zinezimpawu ezikhiphayo ezicupha okokufaka kwe-PLC.
Ufunde futhi ngamabanga ahlukene wezinzwa kanye nokunye okungalungile kwenzwa ngayinye.
