23/01/27I-Dhyana 401D kanye ne-FL20-BW zisebenzisa indlela yokuqalisa nge-optocouupler isolated circuit - izinga lezimboni elisetshenziswa kakhulu elisetshenziselwa ukuhlukanisa izinto zikagesi ezinembile zekhamera kunoma yikuphi ukuhlinza kukagesi kwangaphandle noma ukuphazamiseka. Izidingo zama-optocoupler triggering circuits zihluke kancane kulezo zezinga le-TTL elisetshenziswa kwamanye amakhamera.
I-optocoupler ngokwayo iyingxenye yesimo esiqinile esihlanganisa i-light emitting diode (LED), kanye ne-photosensitive transistor, esebenza njengeswishi. Uma ikhamera ifuna ukukhipha isignali ye-trigger, inani elincane lokukhanya lithunyelwa lisuka ku-LED liye ku-transistor engezwani nokukhanya, elibe selivumela lamanje ukuthi ligeleze kuyo. Kodwa amasekhethi amabili ahlala ehlukene ngokuphelele komunye nomunye, okusho ukuthi ikhamera ivikelekile kunoma yikuphi ukuphazamiseka kukagesi kusuka kudivayisi yangaphandle. Ngokunjalo, okokufaka okokufaka kwenza kusebenze ama-optocoupler ukuze adlulisele amasignali awo kukhamera.
Isiboneloicupha ukusethwa kwamasekhethi acuphayo ahlukanisiwe ne-optocoupler. Ibhokisi eliluhlaza okwesibhakabhaka elinedeshi libonisa okokusebenza ngaphandle kwekhamera. Ulayini obhalwe ukuthi 'TRIGGER OUT' uyiphinikhodi ye-Trigger Out yekhamera. Lonke lolu mjikelezo luyaphindwa esimweni samaphini e-Trigger Out amaningi. Umthombo wamandla kagesi i-VCC2 kanye ne-resistor R3 kufanele kwengezwe ngumsebenzisi.
Ngokungafani nezibangeli ze-TTL lapho uxhumo lwekhamera lwe-trigger out lungakwazi ukulawula ngokuqondile i-voltage ethunyelwa ngekhebuli yokuqalisa, isibonelo ukuthumela isignali ephezulu engu-5V kudivayisi yangaphandle, amasekhethi ahlukaniswe nge-optocoupler asebenza njengeswishi, alawule nje ukuthi ukujikeleza okuphelele kwenziwa noma cha. I-voltage kuleyo seyikhethi kufanele isethwe (ebuye yaziwe ngokuthi 'idonswe phezulu') ngaphandle nge-resistor. Okokugcina ukuze kwakhiwe isekethe ephelele i-trigger circuit kufanele ixhunywe phansi - ikhamera inephinikhodi 'Ye-Trigger Ground' eboniswe esigabeni se-Pin-Out Diagrams ngezansi okumele ixhunywe endaweni kagesi.
Njengoba kukhonjisiwe kumdwebo ongenhla, umthombo wamandla kagesi i-VCC2 kanye ne-resistor R3 kufanele kwengezwe. I-voltage enconyiwe ingu-5V – 24V, kuye nge-voltage i-trigger ekuxhumekeni kwedivayisi yakho yangaphandle elindelwe, nakuba kumadivayisi amaningi lokhu kungase kube ngu-5V. I-resistor R3 inquma yamanje egeleza kusekethe, futhi ukumelana okunconyiwe kungu-1KΩ.
Isetha i-Trigger Out
Uma ikhamera ifuna ukukhipha isignali ye-trigger, i-optocoupler circuit ivaliwe futhi yamanje ingageleza, futhi Idivayisi Yangaphandle izobhalisa ushintsho ku-voltage.
Qaphela ukuthi ukuze usebenzise izikhonkwane ze-trigger out eziningi, udinga amasekhethi ahlukene anomthombo wawo we-voltage kanye ne-resistor.
Kafushane, udinga:
1. Iphinikhodi ye-Trigger Out yekhamera oyisebenzisayo ukuze ixhunywe ku-Trigger In port yocingo lwangaphandle.
2. Okunye okuxhunywe ngokuhambisana nolayini wephinikhodi we-Trigger Out kufanele kube i-resistor R3, bese kuba uchungechunge olunayo umthombo wamandla kagesi i-VCC2, njengoba kuboniswe kumdwebo.
3. Inani le-VCC2 kufanele lisethelwe ku-trigger edingekayo ku-voltage yedivayisi yakho, ngokuvamile engu-5V, nakuba ububanzi obungu-5V-24V busekelwa ikhamera.
4. Inani lika-R3 liyanconywa ukuthi libe ngu-1KΩ
5. Iphinikhodi ye-Trigger Ground yekhamera kufanele ixhunywe phansi.
6. Le sekhethi kufanele iphindwe kuphini ngalinye lokucupha elisetshenzisiwe.
7. Khona-ke umjikelezo wakho usulungele ukuhamba!
Ukusetha i-Trigger In
Ukusethwa kwe-Trigger In kuyefana nalokho kwe-Trigger Out, ixhuma i-Trigger In uxhumano lwekhamera kokuphumayo kwedivayisi yakho yangaphandle kanye nomthombo we-voltage, kanye nephinikhodi yaphansi phansi. Qinisekisa ukuthi i-voltage yokufaka evela ekudonseleni kwangaphandle ingaphakathi kwebanga elingu-5V-24V.
