Kupisa kwekutengesa mukutonga kweseve

Automatic control systems dzakagadzirirwa kuchengetedza zviyero zvakadai sezvino, magetsi, simba, kushandiswa, nezvimwewo. Nzvimbo inokosha mumitambo yakadaro inopiwa kuronga zvirongwa. Zvichienderana nechimwe chinhu, ichi kana kuti chengetedza chirevo chinoshandiswa. Kana isu tichida kutengesa zvinhu, saka mune zvishandiso zvakawanda hapana chikonzero chekuvaka high-speed circuits. Izvi zvinoita kuti ruzivo rwekushandiswa kwechigadziro ruve nyore uye, zvinonyanya kukosha, rinobvumira kushandiswa kwe "kurega" mamiriro emagetsi emagetsi. Iyi nzira inowedzera kuwedzera upenyu hwavo hwebasa uye inopedza nguva yekudzvinyirirwa nguva yekugadzirisa apo kugadzirisa midziyo. Mukutaura kwekugadzirwa, ichi chinhu chinokosha. Chimwe nechimwe chisingatarisirwi chinomira chekugadzirwa kwezvinhu zvinotungamirira kukuderera kwekubuda kwechigadzirwa chekupedzisira, icho, nenzira yepachena, chinokanganisa mutengo waro.

Semuenzaniso, funga purogiramu duku apo mutongi wekushisa anoshandiswa. Kudzora kwemagetsi kune zvinyorwa zviviri - zviratidzo uye zviratidzo zvepfungwa. Ngatitii chiratidzo cheparamende chinofanira kuendeswa pane chimwe chinhu chinobva pachitarisiko chekucherechedza. Mutongi wekushisa anoshandiswa achawedzera zvishoma nezvishoma ikozvino mumhepo inotonhora kusvika kune yakanyanya. Mushure meizvozvo, ichafananidza zviratidzo zvepfungwa uye basa. Kungoti ivo vachienzanisa, chinhu ichocho chichabviswa zvakanaka. Kazhinji, maitiro akadaro hysteresis yekudzoka kushandura / kuvhara - izvi zvakakosha kuti uone kushanda kwakasimba kwemamiriro ose.

Pakutanga, kushandura masheji ekupisa zvinoshandiswa kushandiswa kwemashuruke ane huwandu hwezvakaipa: kuwedzera kwakanyanya mumutoro wezvino, kupfeka kwakasimba kwemasimba ane simba, nezvimwewo. Ikozvino mafashoni anotarisa anotonga masimba modules kubva ma thyristors, triacs, IGBT transistors, nezvimwewo. Chimwe nechimwe chezvikwata zvakadaro zvine zvayo pachedu mukutonga, izvo zvinofanirwa kuongororwa pakugadzira chigadzirwa.

Mikana yakanaka yekutungamirirwa kwezvivako zvakasimba zvekugadzira, somuenzaniso, zviyo zvinotapira, zvine thyristor yekushisa mutevedzeri. The element ine maitiro akanaka ekushanda uye yakazviratidza zvakanaka kwazvo pakushanda nemutoro unoshanda. Muhutungamiri hwemimwe mitambo yemitoro, aya mazvigadziri, ayo akanga ari matsva panguva iyoyo, zvishoma nezvishoma anopa nzira yezvinodiwa zvemazuva ano.

Dzimwe nguva inova inofanirwa kushandisa mudzimu wekushisa mhepo. Muenzaniso wakanaka munyaya ino unogona kushanda sechinhu chiduku chinoshanda mu sauna. Sezvaunogona kuona, kune chirevo chekufananidzira (madigiri Celsius). Mhinduro iyi munyaya iyi chiratidzo kubva kunjodzi yekushisa, iyo iri mukati me sauna. Nenzira imwecheteyo, mvura inotonhorera yekutengesa inoshanda, ndeye rudzi rwe sensor rinoshandurwa. Zvigadzirwa zvakadaro zvinoshandiswawo pakugadzira (zvechokwadi, zvinoratidzwa nesimba guru kwazvo).

Nekuuya kwemasero emagetsi matsva pamusana pemagetsi e semiconductor, zvirongwa "zvekare" zvishoma nezvishoma zvinotsiviwa. Ndiyo chete mitemo yemutemo iyo maitiro aya anoshanda asingashanduki.
