Ndi tchipisi ziti zomwe zimafunikira kupanga fan?

Ndi tchipisi ziti zomwe zimafunikira kupanga mafani

1. Chip chowongolera

Popanga mafani, chimodzi mwazinthu zofunikira kwambiri ndi chip chowongolera, ntchito yake yayikulu ndikuwongolera machitidwe onse opangira mafani komanso kugwiritsa ntchito zida zosiyanasiyana. Chip chowongolera nthawi zambiri chimapangidwa ndi chipangizo chapakati (CPU), kukumbukira ndi mawonekedwe akunja, zomwe zingathandize faniyo kukwaniritsa ntchito zosiyanasiyana, monga kuwongolera zokha, kukonza deta ndi mayankho. Tchipisi zowongolera wamba ndi mndandanda wa STM32F, mndandanda wa ATmega, mndandanda wa PIC ndi zina zotero.

2. sensor chip

Chip cha sensor chimatha kuyeza deta zosiyanasiyana za fan, monga kutentha, liwiro, kuthamanga, ndi zina zotero. Posonkhanitsa detayi, ogwiritsa ntchito amatha kuyang'anitsitsa momwe ntchito ya fan ikuyendera, ndikupeza ndi kuthetsa zolakwika panthawi yake. Chip cha sensor chimaphatikizapo sensa yothamanga, sensa ya kutentha, sensa yothamanga, ndi zina zotero. Chips izi nthawi zambiri zimagwiritsidwa ntchito mu kayendetsedwe ka galimoto. tchipisi wamba sensa ndi LM35, DS18B20, MPX5700 ndi zina zotero.

3. mphamvu chip

Chip champhamvu nthawi zambiri chimakhala gawo lofunikira pazida zosiyanasiyana zanzeru, zimatha kutulutsa ma voliyumu osiyanasiyana, pakali pano komanso mphamvu, kupereka mphamvu yodalirika ya zida, kukulitsa kukhazikika komanso kukhazikika kwa zida. Ma tchipisi amphamvu omwe amafunikira popanga mafani ndi owongolera magetsi, magetsi okhazikika a DC, ndi zina zambiri. Mitundu yamagetsi wamba yamagetsi ndi LM317, 78M05 ndi zina zotero.

Chachinayi, chip processing signal

Chip chopangira ma Signal chimatha kukonza zamakono ndi magetsi kuti akwaniritse cholinga chowongolera magwiridwe antchito ndi kukhazikika kwa zida. Chip chopangira ma siginecha nthawi zambiri chimagwiritsidwa ntchito pamakina owongolera ma mota, omwe amatha kuzindikira algorithm ya proportional integral differential (PID) kuwongolera kuthamanga kwagalimoto, magawo apano ndi ena, ndikuwongolera magwiridwe antchito komanso kukhazikika kwa mafani. Tchipisi zodziwika bwino zama siginecha ndi ADuC7020, STM32F100 ndi zina zotero.

Chachisanu, chip basi

Chip cha basi chimagwiritsidwa ntchito kulumikiza zida ndi zida zosiyanasiyana ndikupanga mlatho wolumikizirana pakati pa zida, zomwe nthawi zambiri zimagwiritsidwa ntchito pamayendedwe owongolera mafani. Tchipisi wamba wa mabasi ndi CAN bus chip, RS-485 bus chip, ndi zina zotero, zomwe zimatha kutumiza deta mosatekeseka, mwachangu komanso modalirika m'malo osiyanasiyana, kupititsa patsogolo kulumikizana kwa chipangizocho, ndikuwongolera magwiridwe antchito komanso kukhazikika.

Izi ndi mitundu ya tchipisi ndi ntchito zawo zofunika pakupanga mafani. Ndi chitukuko chaukadaulo wanzeru, tchipisi zochulukira zidzagwiritsidwa ntchito popanga mafani, kukonza magwiridwe antchito ndi kukhazikika kwa mafani, ndikupanga zopereka zambiri pakukula kwa mafakitale ndi kupita patsogolo kwa sayansi ndiukadaulo.
