Electronic tachometer: chiito uye yezvinoreva musimboti

Kuti optimize injini uchishandisa mamiriro zvaida chaiwo kuyerwa kuti zvingaitwa tichibatsirwa ano mano - zvemagetsi tachometers. mumwe mashandiro kwakadaro zvakarurama kuratidza kuti chisina kutsetseka velocity pakati injini mugodhi, iyo runoratidzwa Zvak / min. Pachishandiswa anokosha mano uye anogona kuona Linear velocity zviri kutenderera mashandiro, izvozvo runoratidzwa m / chik. Electronic tachometer rave zvinobudirira kushandiswa mukurima panguva nokutumwa. Zvinobatsira kuti zvakarurama calibrate injini uye kugadzira kudzorwa hurongwa. midziyo Service ari kushingaira akashandisa izvi zvavo zuva basa.

Uyezve, wemagetsi tachometer rave zvinobudirira kushandiswa Automotive indasitiri. Zvinobatsira vatyairi kuongorora injini nokukurumidza uye kusarudza zvakakodzera zvikuru nokushanda kwadzinoita. Somuenzaniso, apo mwaka kuchinja kana kuchitonhora / kupisa mwaka mudziyo uyu anova chinokosha chokushandisa, nokuti kunosvika upenyu basa motokari.

Kombiyuta yagara kushandiswa zvikuru zvichiwedzera maindasitiri, apo zvakakodzera kungoramba kudzora rotational kumhanya nomubato ari electric motor, injini rekambani combustion turbines, etc. The ndege yemagetsi tachometer mumwe huru zviridzwa kuti kudzora basa Turbo injini. Kubva uchapupu hwake zvakananga upenyu taita uye vatakurwi. Disclaimer tachometer kunogona kutungamirira kunjodzi.

Ngatimboonai basa chikwata ichi muenzaniso duku zano riri nyore kuwana pamambure. Chero yemagetsi tachometer anofanira kugamuchira mashoko kubva Switch, makubhiti uwandu injini nokumukirana kana Linear velocity. Izvi zvinoitwa zvakananga kuonana pamusoro chinjwa chikamu mudziyo pamwe injini mugodhi kana ari kure kushandisa induction kana Laser sensors.

Nezvedu 70-90 anotendeuka kuti waya yokusona-1 ronda akapoteredza makirisito waya kuvesa, kuridza basa inductive Switch, iro rinoshandiswa kuti basa redu achizviita zvemagetsi tachometer. Scheme waya kubatana zviri nyore - mumwe mugumo coils inoenda zvakohwewa, uye wechipiri - iri kudzorwa redunhu. Zvakasara redunhu rine pafiripi-chips on whitekuva, izvo allocates mureza uye transmits nayo counter kuverengwa mudziyo yakavakirwa. Change mari pa chikwata nguva pulses anopiwa mu chienderane redunhu kunoita mashoko anonzwisisika digitaalinen kuratidzwa. Basa Appliance kutenderera yakaiswa Via imwe multivibrator kupomba jenareta tichifunga nhengo Goldstone.

Izvi yemagetsi tachometer anogona kuva mushanduro dzakawanda dzakasiyana. Nokuti ayo Implementation zvinoshandiswa, uye dzimwe mhinduro. Kadambari chikamu ingangodaro kuti vagoronga microprocessor-inobva. Zviri tsika yakanaka achinyora zvirongwa kuti kushanda. Muchiitiko ichi zvakanaka kushandisa microprocessor zvingangoita reprogramming. Kana afunge kukanganwa pamusoro ruzha kutapata ari mudziyo.
