I-DALI VS DMX Lighting Control
Ngokufika kobuchwepheshe, izinhlelo zokulawula izibani ezihlakaniphile zenze ukonga amandla futhi zathuthukisa ukonga kwamandla emahhovisi, izakhiwo, amatiyetha nakwezinye izindawo. Izilawuli zokukhanyisa njenge-DMX ne-DALI ezinye izinhlobo ezidume kakhulu. Basebenzisa isilawuli sokufiphalisa esizenzakalelayo ukuze bonge amandla.
Ukuze uqhathanise izilawuli zokukhanyisa ze-DMX ne-DALI, kufanele wazi imiyalo yesibani ngasinye. Uma usuwuqonda umsebenzi nokusebenza kokulawula ngakunye, uzokwazi ukubona kalula umehluko.
1. Mayelana ne-DALI
Kuhlelo lokulawula ukukhanyisa kwe-DALI, izibani eziningi zixhunywe ngokusebenzisa amaphaneli okulawula amaningi. Kufana nesistimu ehlukanisiwe elawulwa ngayodwa ukuze ifiphaze ukukhanya ngephaneli yokulawula ngayinye. Isilawuli se-DALI sisebenzisa izintambo ezimbili njengolayini wokulawula, futhi singamboza ibanga elingamamitha angama-300. Isilawuli ngasinye se-DALI singaxhunywa kungxube yezibani ezingu-64, sibambe cishe amazinga okukhanya angu-254 ukusuka kumodi ethi "cima" ukuya "kuvuliwe".
2. Mayelana ne-DMX
Ngokungafani ne-DALI, i-DMX isebenzisa iphaneli yokulawula eyodwa ukuze ilawule zonke izici zokukhanyisa. Iwuhlelo lokulawula ukukhanyisa oluphakathi nendawo uma luqhathaniswa ne-DALI emisiwe. I-DMX inezixhumi zompompi eziningi ezisebenzisa i-RS422 noma i-RS485 ukuxhuma izikhanyisi ezengeziwe ekuxhumekeni okukodwa. Umbala wesibani ungabuye ulawulwe ngokusebenzisa i-DMX, okungenakwenzeka ekuxhumekeni kwe-DALI.
3. Umehluko phakathi kwe-DMX ne-DALI
I-1) I-DMX noma i-multiplexing yedijithali iwuhlelo lokulawula isivinini esisheshayo, kuyilapho i-DALI noma isixhumi esibonakalayo sokukhanyisa esilungisekayo kuyisistimu yokulawula ehamba kancane.
2) I-DMX ingaba nokuxhumana okungafika ku-512, kuyilapho i-DALI ingaba nokuxhumana okufinyelele ku-64 kuphela.
3) Kuhlelo lwe-DMX, ukukhuluma okuzenzakalelayo akukwazi ukwenziwa ngenkathi ukukhuluma okuzenzakalelayo kungenzeka ohlelweni lwe-DALI.
4) Nakuba ubude bekhebula bungamamitha angu-300 kuzo zombili izinhlelo, imfuneko yekhebula i-Cat-5 ku-DMX.
5) I-DMX iyiphaneli yokulawula ephakathi nendawo kuyilapho i-DALI iwuhlelo lokulawula olunwetshiwe.
