Mfundo ndi Kukhazikitsa kwa Firiji Control ndi Single-Chip Microcomputers

M'moyo wamakono, mafiriji amawongolera kutentha pogwiritsa ntchito ma microcomputer a single-chip. Kukwera kwamtengo, kumakhala bwino kutentha kukhazikika. Monga mtundu wa microcontroller, ma single-chip microcomputer amagawidwa m'mitundu yosiyanasiyana.

Zodziwika bwino zimatha kuwongolera bwino mafiriji ndikuwongolera magwiridwe antchito ndi magwiridwe antchito a firiji. Choncho, firiji ya firiji sichimapindula kwathunthu ndi ntchito zamakina.

I. Kodi mfundo yoyendetsera firiji pogwiritsa ntchito ma microcomputer a single-chip ndi chiyani kwenikweni?

M'mawu aukadaulo, amatanthauza kukwaniritsa kuyang'anira ndi kuwongolera kutentha, chinyezi, firiji, ndi zina za firiji polumikiza masensa osiyanasiyana ndi ma actuators.

Njira zenizeni ndi izi:

① Ogwiritsa ntchito amayika kutentha, komwe kumakhala ngati mtengo wofotokozera kuti firiji isinthe kutentha.

② Sensa ya kutentha imayang'anira kutentha mkati mwa firiji mu nthawi yeniyeni.

③ Werengani kusintha pakati pa kutentha mkati mwa firiji ndi mtengo wokhazikitsidwa. Ngati kutentha mkati mwa firiji ndipamwamba kuposa kutentha komwe kumayikidwa, microcomputer ya single-chip imayendetsa firiji kuti iyambe firiji kuti ichepetse kutentha mkati mwa firiji. Ngati kutentha kuli kotsika kusiyana ndi mtengo wokhazikitsidwa, microcomputer ya single-chip ya firiji idzalamulira firiji kuti asiye kugwira ntchito kuti kutentha mkati mwa firiji kukhale kokhazikika.

Pamwambapa ndi mfundo ya firiji. Ponena za defrosting ndi ntchito zina, zimayendetsedwanso molingana ndi kutentha, monga kuwonjezera kutentha, kuwongolera kuthamanga kwa fani, etc.

II. Kuwongolera firiji ndi single-chip microcomputer kumatha kutheka kudzera muzizindikiro zowonetsera (kwa ziwonetsero zokha).

Kufotokozera: Ntchitoyi imagwiritsa ntchito jenereta ya nambala mwachisawawa kuti iyerekeze kuwerengera kwa sensor ya kutentha. Muzochita zogwira ntchito, sensa yeniyeni ya kutentha imatha kulumikizidwa ndi pini yolowera ya single-chip microcomputer, ndipo kutentha kwenikweni kumatha kupezeka powerenga mtengo wotuluka wa sensor.

Kufotokozera: Ntchitoyi imayendetsa kuyambika ndi kuyimitsidwa kwa firiji malinga ndi kutentha komwe kulipo komanso kutentha komwe kumayikidwa. Ngati kutentha kwapano kuli kopitilira muyeso womwe mukufuna, firiji imayamba. Ngati kutentha kwapano kuli kochepa kapena kofanana ndi kutentha komwe mukufuna, firiji idzayimitsidwa.

Kufotokozera: Ntchitoyi imagwiritsidwa ntchito kusonyeza kutentha komwe kulipo komanso momwe firiji imayendera. Muzogwiritsira ntchito, mawonekedwe a kristalo amadzimadzi kapena zipangizo zina zowonetsera zingagwiritsidwe ntchito kusonyeza chidziwitso ichi kuti ogwiritsa ntchito adziwe momwe firiji imagwirira ntchito nthawi iliyonse.

III. Chidule

Kupyolera mu kukhazikitsidwa kwa zizindikiro pamwambapa, single-chip microcomputer imatha kuyendetsa bwino kutentha ndi firiji dongosolo la firiji ndikuwongolera magwiridwe antchito ndi magwiridwe antchito afiriji. Zoonadi, ichi ndi chitsanzo chophweka, chomwe chingalole makasitomala kudziwa zomwe zili mu teknoloji ya firiji. Zimathekanso kudzera mu tchipisi, owongolera ndi maukadaulo angapo a firiji. Mafiriji ambiri ogulitsa zakudya ndi mafiriji azachipatala amayendetsedwa ndi ma microcomputer a single-chip. Mutha kuganiza kuti ikuyendetsedwa ndi kakompyuta kakang'ono, ndipo idzakhala ndi mapulogalamu ambiri m'moyo weniweni. Kukwera kwaukadaulo, kumapangitsa kuti ogwiritsa ntchito azitha kumva bwino.
