Izimiso kanye Nokusetshenziswa Kokulawulwa Kwefriji Ngama-Microcomputer Angama-Single-Chip

Empilweni yanamuhla, amafriji alawula izinga lokushisa ngamakhompyutha amancane ane-chip eyodwa. Uma intengo iphakeme, kuba ngcono ukuzinza kwezinga lokushisa. Njengohlobo lwe-microcontroller, amakhompyutha amancane ane-chip eyodwa ahlukaniswe ngezinhlobo ezahlukene.

Ezejwayelekile zingafinyelela ukulawula okunembile kwamafriji futhi zithuthukise ukusebenza kahle kwamafriji. Ngakho-ke, ukuqandisa amafriji akufezwa ngokuphelele ngemisebenzi yemishini.

I. Iyini ngempela isimiso sokulawulwa kwesiqandisi ngamakhompyutha amancane ane-chip eyodwa?

Ngamagama ochwepheshe, kubhekisela ekufezeni ukuqapha nokulawula izinga lokushisa, umswakama, uhlelo lokuqandisa, njll. lwesiqandisi ngokuxhuma izinzwa ezahlukene kanye nama-actuator.

Izinyathelo ezithile yilezi ezilandelayo:

① Abasebenzisi basetha izinga lokushisa, elisebenza njengenani elibhekisela esiqandisini ukuze kulungiswe izinga lokushisa.

② Inzwa yokushisa iqapha izinga lokushisa ngaphakathi kwesiqandisi ngesikhathi sangempela.

③ Bala ushintsho phakathi kwezinga lokushisa elingaphakathi kwesiqandisi kanye nenani elibekiwe. Uma izinga lokushisa elingaphakathi kwesiqandisi liphakeme kunezinga lokushisa elibekiwe, i-single-chip microcomputer ilawula uhlelo lokuqandisa ukuze luqale ukuqandisa ukuze lwehlise izinga lokushisa elingaphakathi kwesiqandisi. Uma izinga lokushisa liphansi kunenani elibekiwe, i-single-chip microcomputer yesiqandisi izolawula uhlelo lokuqandisa ukuze luyeke ukusebenza ukuze kugcinwe izinga lokushisa elingaphakathi kwesiqandisi lizinzile.

Lokhu okungenhla kuyisimiso sokuqandisa. Ngokuphathelene nokuncibilikisa kanye neminye imisebenzi, kulawulwa futhi ngokwezinga lokushisa, njengokukhulisa izinga lokushisa, ukulawula ijubane lokujikeleza kwefeni, njll.

II. Ukulawulwa kwesiqandisi yikhompyutha encane ene-chip eyodwa kungatholakala ngamakhodi okubonisa (okwereferensi yokubonisa kuphela).

Incazelo: Lo msebenzi usebenzisa i-generator yezinombolo ezingahleliwe ukulingisa ukufundwa kwenzwa yokushisa. Ezinhlelweni ezisebenzayo, inzwa yokushisa yangempela ingaxhunywa kuphini yokufaka yekhompyutha encane ene-chip eyodwa, futhi izinga lokushisa langempela lingatholakala ngokufunda inani lokukhipha lenzwa.

Incazelo: Lo msebenzi ulawula ukuqala nokuyeka kohlelo lokuqandisa ngokuya ngokushisa kwamanje kanye nokushisa okuqondiwe okubekiwe. Uma izinga lokushisa lamanje liphakeme kunokushisa okuqondiwe, uhlelo lokuqandisa luzoqaliswa. Uma izinga lokushisa lamanje liphansi noma lilingana nokushisa okuqondiwe, uhlelo lokuqandisa luzomiswa.

Incazelo: Lo msebenzi usetshenziselwa ukubonisa izinga lokushisa lamanje kanye nesimo sesistimu yokuqandisa. Ezisetshenzisweni ezingokoqobo, isibonisi sekristalu eliwuketshezi noma amanye amadivayisi okubonisa angasetshenziswa ukubonisa lolu lwazi ukuze abasebenzisi bazi isimo sokusebenza sesiqandisi nganoma yisiphi isikhathi.

III. Isifinyezo

Ngokusebenzisa amakhodi angenhla, i-microcomputer ene-chip eyodwa ingalawula ngempumelelo izinga lokushisa kanye nohlelo lokuqandisa lwesiqandisi futhi ithuthukise ukusebenza kanye nokusebenza kahle kwesiqandisi. Yiqiniso, lesi yisibonelo esilula nje, esingazisa amakhasimende ngokucacile okuqukethwe kobuchwepheshe besiqandisi. Kuphinde kufezwe ngama-chips, abalawuli kanye nochungechunge lobuchwepheshe bokuqandisa. Iningi leziqandisi zokudla zezentengiselwano kanye neziqandisi zezokwelapha zilawulwa ama-microcomputer ane-chip eyodwa. Ungacabanga ngakho njengokulawulwa yikhompyutha encane, futhi kuzoba nohlu olubanzi lwezinhlelo zokusebenza empilweni yangempela. Uma okuqukethwe kobuchwepheshe kuphakeme, ulwazi lomsebenzisi luba ngcono.
