Napedyo Switch: zvinhu uye pangave

Muupenyu hwezuva nezuva, kuti napedyo Switch unoshandiswa zvinenge kose. On motokari zvinobatsira pamwe kupaka, pamusoro conveyor inocherechedza kufamba zvigadzirwa mu dzeserura ano dzevhudzi ari keypad pashure pokushandisa mudziyo kuti nzeve yenyu. Muupenyu hwezuva nezuva, ndiko chishamiso zvigadzirwa, zvakare, akawana nzvimbo yaro. Kwakadaro midziyo yemagetsi Vanoshandisa kuiswa panzvimbo chinja, somuenzaniso, mumugwagwa. Kana mangoti wasvika mumba, chiedza rwoga Anovhura, uye pashure penguva kure. Vakachengeteka hurongwa hazvibviri kuita pasina sensors.

Kusiyanisa napedyo sensors mhando: capacitive, inductive, Manyiminya, ultrasonic, microwave, magnetically, etc. pyrometric Output bhuku rinorondedzera imwe mudziyo kunotsamira ayo uchishandisa pfungwa.

Capacitive Switch kusvika dzinowanzotsigi- raishandiswa vakachengeteka hurongwa nokuti anoona rava kusvika chinhu uye zvichipfuura haugoni. Izvi chinosiyanisa kubva ultrasonic kana michini analogs achiona kure uko kunobva zvakasimba pamusoro pechiso chinhu. Somuenzaniso, imwe michini napedyo Switch anopindura chafariz - michini - nematanda. Ultrasonic mano emit awekutanga, uye ipapo anogamuchira kunooneka matanda pachiso. By nheyo kushanda, ichi napedyo Switch zvikuru zvakafanana locator. Uye akaita zvakanaka zvose, kubva dzakaoma hukawanika airatidza chiratidzo chakanaka, asi kubva nyoro - kwete chaizvo. Uye anokwanisa yokunzvenga nayo, chete takapfeka chinhu nyoro. Nezvikonzero izvi, zvakanaka kushandisa capacitive mhando sensors, kunyanya munyika zvichikurukura mano kuchengetedza inokosha uye makuru zvinhu. Panyaya iyi, iyo kanyanga waya ari muchimiro yakatambarara hwavapo kuti fenzi uye zvakabatana kuburikidza chiduku kukwanisa capacitor kune huru chikwata.

Capacitive sensors uyewo kuuya mhando dzakawanda:

1. Sensors pamusoro capacitors. Kuti zvirongwa ekupedzisira vasanonoka chikamu mudziyo. Izvi mhando unoshandiswa apo asina zvinodiwa kutapata uye yakakwirira nehanya, somuenzaniso, Nyevero kubata simbi zvinhu.

2. Capacitive sensors vachishandisa Frequency kudzora redunhu. Izvi mhando mudziyo zvishoma kubatwa redhiyo chipingaidzo uye crosstalk pane Namano capacitors. Izvi mhando zvingashandiswa mumba kutsausa pasi chiedza, uye zvichingodaro. N.

3. differential-capacitive Switch. Vakasiyana pamusoro apa pakuti vane antennas maviri panzvimbo imwe, kuti anopa kudzvinyirira migumisiro okunze (mvura, chando, madutu, chando uye zvakafanana. D.). munda Avo chikumbiro rakasiyana sensors pamusoro LC-remudunhu. Musiyano chete ndechokuti unofanira kugadza mumwe kanyanga.

4. Resonant Capacitive sensors. rukungiso mureza rikaitika mazano redunhu, riri rimwe ubatanidzwewo kudzikama mamiriro pakureva mukuru-kakawanda chiratidzo jenareta. Sezvo hwakabatana redunhu using chiduku kukwanisa ane capacitor (chinhu chaikosha vanoenderana kurwisa mudunhu). sensors kwakadaro kunogona kushandiswa zvese mumunda kumaruwa uye mumadhorobha dzoga, asi kunyanya pedyo redhiyo zvinyorwa simba.
