Kufa gasp zvinoreva kuti kana system voltage isingakwanise kusangana neyakajairwa mashandiro eiyo system, sisitimu inongotumira chiratidzo kumucheto wemusoro kuti uudze musoro kutiONUinogona kusashanda nemazvo, uye magumo emusoro achapa maitiro ekuburitsa chiteshi chakarongerwa iyoONU
TheONUmaster chip mugadziri achagadzira Dying gasp performance module (yakaenzana nevoltage comparator) muchip kana uchigadzira chip. Iyi module inotarisisa yekunze yekupinza voltage kuti ione iyo Dying gasp basa. Naizvozvo, mukati menguva inoshanda yeKufa gasp chiratidzo, marudzi ese emagetsi ekushanda kwakajairika kwechip haagone kuve ari pasi peiyo shoma yekushandisa voltage inotsanangurwa mune yakatarwa. pfungwa uye kushanda voltage chip haigoni kuva shoma pane Dying gasp chiratidzo nguva kureba.
Kufa gasp Inoshandura "kutora mweya usati wafa", uchishandisa magetsi ekupedzisira kutumira ruzivo rwekupedzisira. Dunhu rine zvikamu zviviri:
1. Hombe capacitor simba rekuchengetedza. Kana iyo yekupinza yekunze ikatadza, nguva yekuti simba rakachengetwa muhombe capacitor riburitswe kuti rikwanise kushanda kuti system yese ifeme zvakare kazhinji yakawanda ms. InONUmidziyo, inowanzodzorwa pane anopfuura 10ms. Dunhu iri nyore - hombe capacitor (electrolytic capacitor, kugona uye kushandiswa kwesimba kweiyo system uye huwandu hwemagetsi hunogona kudzorwa), diode, voltage comparator. Basa re capacitor pano ndere kuchengetedza simba, diode inoyerera yemahara, uye voltage comparator inoona kuenzanisa kwevoltage kukonzeresa chiratidzo chekuvhiringidza.
2. Chipi chikuru cheONUine pini yekupinza yekutarisa voltage comparator level. Kana iyo Dying gasp ikamutswa, inogona kutumira chiratidzo chekukanganisa, ichiita kuti sisitimu ipinde munzvimbo ye "kuita kuda", uye pakupedzisira kutumira humwe hurefu hwechiratidzo kumucheto wemusoro mukati meashoma ms.
