Dareemka dareenka

Dareemka dareenka sawirku waa dareemaha elektiroonigga ah ee ugu habboon kaas oo xakameyn kara beddelka tooska ah ee wareegga sababtoo ah isbeddelka iftiinka ee waaberiga iyo mugdiga (qorrax soo baxa iyo qorrax dhaca).Dareemaha sawir-qaadista ayaa si toos ah u xakameyn kara furitaanka iyo xidhitaankaNalalka LED-kaiyadoo loo eegayo cimilada, xilliga iyo gobolka.Maalmaha dhalaalaya, isticmaalka tamarta waa la dhimay iyadoo la dhimayo awoodda wax soo saarka.Marka la barbardhigo isticmaalka nalalka dhaadheer, dukaanka ku habboon ee leh aagga 200 oo mitir oo laba jibbaaran wuxuu yarayn karaa isticmaalka tamarta 53% ugu badnaan, nolosha adeeguna waxay ku saabsan tahay 50000 ~ 100000 saacadood.Guud ahaan, nolosha adeegga ee nalalka LED-ku waxay ku saabsan yihiin saacadaha 40000;Midabka iftiinka ayaa sidoo kale lagu beddeli karaa RGB si iftiinku u noqdo mid midabo badan iyo jawiga mid firfircoon.

Dareemaha infrared

Dareemaha infrared-ku wuxuu u shaqeeyaa inuu ogaado infrared-ka uu sii daayo jidhka bini'aadamka.Mabda'a ugu muhiimsan waa: 10 jeer ee qiiqa jidhka bini'aadamka μ Shucaaca infrared ee ku saabsan M waxaa wanaajiyay muraayada filter Fresnel oo lagu soo ururiyay walxaha pyroelectric PIR detector.Marka ay dadku dhaqaaqaan, booska sii daaya ee shucaaca infrared ayaa isbeddeli doona, curiyaha wuxuu lumin doonaa dheelitirka kharashka, wuxuu soo saaraa saamaynta pyroelectric wuxuuna sii daayaa kharashka dibadda.Dareemka infrared-ka ayaa u rogi doona isbeddelka tamarta shucaaca infrared-ka iyada oo loo marayo lenska shaandhada Fresnel una beddelo calaamad koronto, beddelidda Thermoelectric.Marka aanay jirin jidh bini'aadmi ah oo ku dhaqaaqa aagga ogaanshaha ee qalabka baaraha infrared-ka ee dadban, dareemaha infrared ayaa dareema oo kaliya heerkulka asalka ah.Marka jidhka bini'aadamku galo aagga lagu ogaanayo, iyada oo loo marayo lenska Fresnel, dareemaha infrared ee pyroelectric ayaa dareemaya farqiga u dhexeeya heerkulka jidhka bini'aadamka iyo heerkulka asalka ah, Ka dib markii calaamadda la ururiyo, waxaa la barbar dhigaa xogta hadda jirta ee nidaamka si loo xukumo. haddii qof iyo ilo kale oo infrared ah ay galaan aagga la ogaanayo.

Iftiinka Dhaqdhaqaaqa LED

Dareemaha Ultrasonic

Dareemayaasha Ultrasonic, oo la mid ah dareemayaasha infrared, ayaa aad iyo aad loogu isticmaalay ogaanshaha tooska ah ee walxaha dhaqaaqa sanadihii ugu dambeeyay.Dareemaha ultrasonic inta badan wuxuu isticmaalaa mabda'a Doppler si uu u sii daayo hirarka ultrasonic ee soo noqnoqda ee ka sarreeya aragtida jidhka bini'aadamka iyada oo loo marayo oscillator-ka crystal.Guud ahaan, 25 ~ 40KHz mawjada ayaa la doortaa, ka dibna moduleka xakamaynta ayaa ogaanaya inta jeer ee mawjada muuqata.Haddii ay jiraan dhaqdhaqaaqa walxaha ee aagga, inta jeer ee mawjada muuqata ayaa isbeddeli doonta wax yar, taas oo ah, saamaynta Doppler, si loo xukumo dhaqdhaqaaqa walxaha aagga iftiinka, Si loo xakameeyo furaha.

Dareemaha heerkulka

Dareemka heerkulka NTC ayaa si weyn loogu isticmaalaa ilaalinta heerkulkaLEDnalalka.Haddii isha iftiinka LED ee awoodda sare leh loo qaato nalalka LED-ka, hiitarka aluminium baal badan waa in la qaataa.Sababtoo ah booska yar ee nalalka LED-ka ee iftiinka gudaha, dhibaatada kuleylka kuleylka ayaa weli ah mid ka mid ah cilad farsamo ee ugu weyn ee hadda.

Kuleylka liidata ee nalalka LED-ku waxay u horseedi doonaan iftiinka hore ee iftiinka iftiinka LED sababtoo ah kulaylka.Ka dib marka nalka LED-ka la shido, kulaylka waxaa lagu hodmin doonaa daboolka nalka sababtoo ah kor u kaca tooska ah ee hawada kulul, taas oo saameyn doonta nolosha adeegga korontada.Sidaa darteed, marka la naqshadeynayo nalalka LED-ka, NTC wuxuu u dhowaan karaa radiyeer aluminium u dhow isha iftiinka LED si loo ururiyo heerkulka nalalka wakhtiga dhabta ah.Marka heerkulka hiitarka aluminium ee koobka laambada uu kordho, wareeggan waxaa loo isticmaali karaa in si toos ah loo yareeyo wax soo saarka hadda jira ee isha joogtada ah si loo qaboojiyo nalalka;Marka heerkulka hiitarka aluminium ee koobka laambada uu kor u kaco ilaa xadka xadka, sahayda korontada LED si toos ah ayaa loo dami doonaa si loo ogaado heerkulka ka sarreeya ee laambada.Marka heerkulku hoos u dhaco, nalka ayaa si toos ah mar kale shidmi doona.

Dareemka codka

Dareemka xakamaynta dhawaaqu wuxuu ka kooban yahay dareeraha xakamaynta codka, cod-weyneeye, wareegga xulashada kanaalka, wareegga furitaanka dib u dhigista iyo wareegga xakamaynta thyristor.Xakamee in la bilaabo wareegga kantaroolka iyadoo lagu saleynayo natiijooyinka isbarbardhigga dhawaaqa, oo deji qiimaha asalka ah ee dareemaha xakamaynta codka oo leh maamulaha.Dareemka xakamaynta dhawaaqa wuxuu si joogto ah u barbar dhigaa xoojinta dhawaaqa dibadda iyo qiimaha asalka ah, wuxuuna u gudbiyaa calaamadda "codka" xarunta xakamaynta marka ay dhaafto qiimaha asalka ah.Dareemaha xakamaynta codka ayaa si weyn loogu isticmaalaa waddooyinka iyo meelaha iftiinka dadweynaha.

Dareemka kicinta microwave

Dareemka kicinta mikrowave waa sheyga dhaqaaqa oo loo qaabeeyey kuna saleysan mabda'a saameynta Doppler.Waxay ogaataa in booska shaygu uu u socdo si aan xiriir ahayn, ka dibna wuxuu abuuraa hawlgalka beddelka ee u dhigma.Marka qof soo galo aagga dareenka oo uu gaaro baahida iftiinka, dareemaha dareemaha ayaa si toos ah u furmi doona, qalabka xamuulka ayaa bilaabi doona inuu shaqeeyo, nidaamka dib u dhigista ayaa la bilaabi doonaa.Ilaa inta jidhka bini'aadamku aanu ka tagin aagga dareenka, qalabka rarka ayaa sii wadi doona inuu shaqeeyo.Marka jidhka bini'aadamku ka tago aagga dareenka, dareemaha wuxuu bilaabaa inuu xisaabiyo daahitaanka.Dhammaadka daahitaanka, dareemaha dareemaha ayaa si toos ah u xirma oo qalabka xamuulka ayaa joogsada shaqada.Runtii badbaado leh, habboon, caqli badan iyo tamar-badbaadin.
