Muhimmin abubuwan lura game da Mitsubishi lif ƙofa matsayi photoelectric switches

MON1/0=2/1 Misalin Aiki

Ta hanyar saita MON1=2 da MON0=1 akan allon P1, zaku iya duba sigina masu alaƙa da kewayar ƙofa. 7SEG2 na tsakiya shine siginar da ke da alaƙa da ƙofar gaba, kuma 7SEG3 na dama shine siginar da ke da alaƙa ta baya. Ana nuna ma'anar kowane sashi a cikin hoton da ke ƙasa:

Don dubawa a kan yanar gizo da magance matsala, ya kamata a mayar da hankali kan bangarori biyu.

Na farko shine ko sigina na iya canzawa daidai lokacin buɗe kofa da rufewa.(Duba ko akwai gajeriyar kewayawa, haɗin da ba daidai ba, ko lalacewar bangaren)

Na biyu shine ko jerin ayyukan siginar CLT, OLT, G4, da 41DG daidai ne yayin buɗe kofa da rufewa.(Duba ko akwai kuskure a matsayi da girman kofa photoelectric da GS switches)

① Yanayin atomatik na rufe ƙofar jiran aiki

② An karɓi siginar buɗe ƙofar

③ Ana ci gaba da buɗe kofa

④ Buɗe kofa a wurin (Ƙananan axis na gani kawai an toshe, buɗe kofa a cikin yanayin wuri, OLT a kashe)

⑤ An karɓi siginar rufe ƙofar

⑥ An cire shi daga matsayin aikin OLT

⑦ Tsarin rufe kofa

⑧ Ƙofar da za a rufe a wuri ~~ An rufe a wurin

Ana kunna siginar G4 a fili kafin siginar CLT.

Binciken matsalolin da ke akwai na sauya matsayi na axis biyu

1.Matsaloli a cikin amfani da kan-site na dual-optical axis matsayi sauya
Matsalolin da ke kan rukunin sun haɗa da:
(1) Ba a haɗa maɓalli na photoelectric zuwa na'urar gajeriyar kewayawa amma an haɗa kai tsaye zuwa allon da aka buga, wanda ke sa wutar lantarki ta ƙone, wanda ya zama ruwan dare;
(2) Maɓalli na hoto ba a haɗa shi da kayan aiki na gajere ba amma an haɗa shi kai tsaye zuwa allon da aka buga, wanda ke haifar da lalacewa ga allon injin ƙofar (ko dai resistor ko diode na iya lalacewa);
(3) An haɗa resistor na gajeren lokaci ba daidai ba, yana haifar da lalacewa ga maɓallin hoto (ya kamata a haɗa shi da kebul na 1, amma kuskuren haɗa shi da kebul na 4;
(4) Dual-optical axis baffle ba daidai ba ne.

2.Tabbatar da nau'in canjin matsayi na photoelectric
Zane-zane na maɓalli na axis biyu ana nuna shi a hoto na 1 a ƙasa.

3. Tabbatar da baffle canza matsayi

Gefen hagu shine madaidaicin buɗe kofa, kuma gefen dama shine madaidaicin ƙofar

Lokacin da ƙofar motar ta motsa zuwa hanyar rufe kofa, jujjuyawar L mai siffa za ta fara toshe axis 2 sannan kuma axis na gani 1.
Ya kamata a lura cewa lokacin da baffle L-dimbin jujjuyawar ya toshe axis 2 na gani, hasken LOLTCLT akan panel ɗin injin kofa zai haskaka, amma hasken nunin hasken axis photoelectric dual na gani ba zai haskaka ba; har sai da baffle na L-dimbin jujjuyawar ya toshe duka axis na gani na 2 da axis na gani na 1, hasken mai nuna alama na canjin matsayi na axis dual zai haskaka, kuma yayin wannan tsari, hasken LOLTCLT akan kwamitin injin kofa zai kasance koyaushe; sabili da haka, hukuncin rufe kofa ya kamata ya dogara ne akan yanayin haske mai nuna alama na dual Optical axis photoelectric.
Saboda haka, bayan amfani da dual Optical axis photoelectric, an nuna ma'anar buɗewar kofa da siginar rufewa a cikin Tebur 1 da ke ƙasa.

Tebur 1 Ma'anar buɗewar kofa na hoto mai axis biyu da wuraren rufewa

Lura:
(1) Siginar axis na gani na 1 an samo shi daga toshewar OLT;
(2) Siginar axis na gani na 2 an samo shi daga plug-in CLT;
(3) Lokacin da aka rufe ƙofar gabaɗaya, alamar axis na gani biyu tana haskakawa saboda an toshe axis na gani 1. Idan axis 2 kawai aka toshe, hasken mai nuna alama ba zai haskaka ba.

4. Tabbatar da ko canjin matsayi na axis biyu ya lalace
Zaka iya amfani da multimeter don gano ƙarfin lantarki na 4-3 fil na OLT da CLT plug-ins don sanin ko sauyawar matsayi na dual-axis ya lalace. Ana nuna takamaiman halin da ake ciki a cikin Tebura 2 da ke ƙasa.

Lura:
(1) Lokacin aunawa, haɗa jan bincike na multimeter zuwa fil 4 da baƙar fata zuwa fil 3;
(2) Axis na gani 1 yayi daidai da toshewar OLT; Axis na gani 2 yayi daidai da plug-in CLT.
