Ukufa kokuphefumula kusho ukuthi lapho i-voltage yesistimu ingakwazi ukuhlangabezana nokusebenza okuvamile kwesistimu, uhlelo luzothumela ngokuzenzakalelayo isignali ekupheleni kwekhanda ukutshela ukuphela kwekhanda ukuthiI-ONUingase ingasebenzi kahle, futhi isiphetho sekhanda sizonikeza ukusabela kokukhulula isiteshi esasihlelelwe i-I-ONU
II-ONUUmkhiqizi we-chip oyinhloko uzoklama imojula yokusebenza kwe-Ding gasp (elingana nesifanisi se-voltage) ku-chip lapho iklama chip. Le mojula iqapha amandla kagesi angaphandle ukuze ibone umsebenzi we-Ding gasp. Ngakho-ke, phakathi nesikhathi esisebenzayo sokufa kwesignali yokuphefumula, zonke izinhlobo zama-voltage okusebenza okujwayelekile kwe-chip azikwazi ukuba ngaphansi kwe-voltage encane yokusebenza echazwe ekucacisweni.. Okusho ukuthi, umehluko phakathi kwe-voltage yokuqala yokuqapha. iphuzu kanye ne-voltage yokusebenza ye-chip ayikwazi ukuba ngaphansi kobude besikhathi sesignali ye-Ding gasp.
Ukufa umoya Kuhumusha ukuthi "thatha umoya ngaphambi kokufa", usebenzisa ugesi wokugcina ukuthumela ulwazi lokugcina lwesimo. I-circuit ehlanganisa izingxenye ezimbili:
1. Isitoreji samandla esikhulu se-capacitor. Uma okokufaka kwangaphandle kwehluleka, isikhathi sokuthi amandla agcinwe ku-capacitor enkulu akhululwe ukuze akwazi ukusebenzela uhlelo lonke ukuthi luphefumule futhi ngokuvamile singu-ms ambalwa. KuI-ONUimishini, ngokuvamile ilawulwa ngaphezu kuka-10ms. I-circuit ilula - i-capacitor enkulu (i-electrolytic capacitor, umthamo kanye nokusetshenziswa kwamandla kwesistimu kanye nobubanzi be-voltage bungalawulwa), i-diode, i-voltage comparator. Umsebenzi we-capacitor lapha ukugcina amandla, i-diode igeleza mahhala, futhi isiqhathanisi se-voltage sibona ukuqhathaniswa kwe-voltage ukuqala isignali yokuphazamisa.
2. I-chip eyinhloko yeI-ONUinephinikhodi yokufaka yokuqapha ileveli yesiqhathaniso samandla kagesi. Lapho i-Dying gasp icushiwe, ingathumela isignali yokuphazamisa, yenze uhlelo lungene esimweni "sokwenza intando", futhi ekugcineni ithumele ubude obuthile besiginali ekugcineni kwekhanda phakathi kwama-ms ambalwa.
Siyabonga ngokubuyekeza isingeniso se-Ding gasp ofI-ONUelethwe yi-Shenzhen HDV Phoelectron Technology Co., LTD., kanye nemikhiqizo yethu ehlobene nenethiwekhi eshisayo ihlanganisa izinhlobo ezahlukene zeI-ONUimikhiqizo yochungechunge, kuhlanganise ne-ACI-ONU/ ukuxhumanaI-ONU/ ehlakaniphileI-ONU/ ibhokisiI-ONU/ Imbobo ye-PON emibiliI-ONUnjalo njalo. EphezuluI-ONUimikhiqizo yochungechunge ingasetshenziselwa izidingo zenethiwekhi zezimo ezihlukahlukene. Siyakwamukela ukuthi ube nokuqonda okuningiliziwe kwezobuchwepheshe kwemikhiqizo.
