Kodi njira zowongolera za thermostat ndi ziti?
Pali njira ziwiri zazikulu zowongolera za thermostat: ON/OFF control ndi PID control.
Kuwongolera kwa 1.ON / OFF ndi njira yosavuta yolamulira, yomwe ili ndi zigawo ziwiri zokha: ON ndi OFF.Pamene kutentha kwayikidwa kumakhala kotsika kuposa kutentha komwe mukufuna, thermostat idzatulutsa ON chizindikiro kuti iyambe kutentha;Kutentha kukakhala kopitilira muyeso womwe mukufuna, chotenthetsera chimatulutsa chizindikiro cha OFF kuti chiyimitse kutentha.Ngakhale njira yolamulira iyi ndi yophweka, kutentha kumasinthasintha mozungulira mtengo wamtengo wapatali ndipo sikungakhazikitsidwe pamtengo wokhazikitsidwa.Chifukwa chake, ndizoyenera nthawi zomwe kuwongolera kuwongolera sikufunikira.
Kuwongolera kwa 2.PID ndi njira yowongolera kwambiri.Zimaphatikiza ubwino wa kulamulira kofanana, kulamulira kophatikizana ndi kulamulira kosiyana, ndikusintha ndi kukhathamiritsa malinga ndi zosowa zenizeni.Mwa kuphatikiza zowongolera zofananira, zophatikizika, ndi zosiyana, owongolera a PID amatha kuyankha mwachangu kusintha kwa kutentha, kukonza zokha zopatuka, ndikupereka magwiridwe antchito okhazikika.Chifukwa chake, kuwongolera kwa PID kwagwiritsidwa ntchito kwambiri pamakina ambiri owongolera mafakitale.
Pali njira zambiri zotulutsira thermostat, makamaka kutengera malo ake owongolera komanso mawonekedwe a zida zowongolera zomwe mukufuna.Zotsatirazi ndi zina zomwe zimagwiritsidwa ntchito potulutsa thermostat:
Voltage linanena bungwe: Iyi ndi imodzi mwa njira zofala linanena bungwe kulamulira boma ntchito chipangizo ndi kusintha matalikidwe a voteji chizindikiro.Kawirikawiri, 0V imasonyeza kuti chizindikiro chowongolera chazimitsidwa, pamene 10V kapena 5V imasonyeza kuti chizindikiro chowongolera chimayatsidwa, pomwe chipangizo chowongolera chimayamba kugwira ntchito.Njira yotulutsa iyi ndi yoyenera kuwongolera ma mota, mafani, magetsi ndi zida zina zomwe zimafunikira kuwongolera pang'onopang'ono.
Kutulutsa kwa relay: Kupyolera mu relay yoyatsa ndi kuzimitsa siginecha yowongolera kutentha.Njira imeneyi nthawi zambiri ntchito kulamulira mwachindunji katundu zosakwana 5A, kapena kulamulira mwachindunji contactors ndi relay wapakatikati, ndi kulamulira kunja katundu mkulu-mphamvu kudzera contactors.
Solid state relay drive voltage output: Thamangitsani zotulutsa zolimba za state state ndi siginecha yotulutsa magetsi.
Solid state relay imayendetsa kutulutsa kwamagetsi.
Kuphatikiza apo, pali njira zina zotulutsa, monga thyristor phase shift trigger control, thyristor zero trigger output ndi voteji yosalekeza kapena kutulutsa ma siginecha apano.Mitundu iyi yotulutsa ndi yoyenera kumadera osiyanasiyana owongolera komanso zofunikira za chipangizocho.
