I-AVT 5599 Imanuwali Yomnikazi Wokushintsha Iziteshi Ezi-4 elawulwa kude
Idivayisi ivumela amadivayisi amane ukuthi avulwe/avale ukude kusetshenziswa izilawuli ezivamile ze-IR ezivela kumishini evamile. I-advan yayo engangabazekitage ukuthi ingasetshenziswa cishe nanoma yisiphi isilawuli kude se-infrared, futhi inqubo yokufunda amakhodi okulawula kude iyancipha ibe izinyathelo ezimbalwa ezilula.
Izici
- I-ATmega8 microcontroller.
- I-PCB enobukhulu obungu-74 mm×145 mm ifakwe endaweni ebiyelwe i-Z4.
- Ukunikeza 230 VAC.
- Ukuvula/ukuvala okuzimele kwama-relay angu-4 kusetshenziswa isidlulisi se-infrared esivela kumpahla ye-RTV.
Incazelo yesifunda
Umdwebo wohlelo weswishi uboniswa kuMfanekiso 1. Idivayisi inikwa amandla kusuka kumapayipi amakhulu angu-230 VAC nge-transformer ye-TS1. Ngemva kokudlula ku-rectifier (M1) kanye nesihlungi (C1, C3, C5, C6), ivolumutagi-e iya kusinzinzisi se-US4, esihlinzeka ngo-+5 V. Ingxenye elawula ukusebenza kwayo yonke idivayisi iyi-microcontroller (US1) ATmega8, futhi isofthiwe equkethwe kuyo inomthwalo wemfanelo wokuhlaziya nokukhipha amasiginali okusakaza nge-infrared. I-microcontroller ivalwe yi-8 MHz quartz resonator (Q1). Umamukeli wemisebe ye-infrared evela kubashayeli bezindiza iyi-chip ekhethekile ye-US3 yohlobo lwe-TSOP4836, equkethe zonke izakhi ezidingekayo ukuze uthole amasignali e-infrared.
Ukwandisa ukuzwela kowamukelayo, inikezwa ngesihlungi esenziwe nge-resistor R11 kanye ne-capacitor C4. Njengoba okukhiphayo stagiziteshi zokushintsha ngazinye idivayisi ezisebenzisa isekethe (US2) uhlobo lwe-ULN2003A, equkethe 7 stagi-transistor ampama-lifiers anama-diode okuvikela avumela ukulawula okuqondile kwama-relay. Umsebenzi obalulekile owenziwa uhlelo lwe-microcontroller ukuthola isignali evela kumamukeli we-infrared kanye namafreyimu ahlukanisayo kule siginali, okungukuthi amakhodi athunyelwe esuka
Isilawuli kude se-IR. Uhlaka olunjalo luvamise ukuqukatha ukusuka kweshumi nambili ukuya kweshumi nambili, ubude balo nezikhathi zokumisa isikhashana ngokuvamile zisukela ku-0.2 ms ukuya ku-3 ms. Isoftware ivumela ukukala amapulse afika ku-8 ms. Uma okokufaka kwesignali kuhlala kungashintshiwe ku-8 ms, lokhu kuyinkomba yokuthi ukudluliswa kohlaka olulodwa kuqediwe futhi i-pulse elandelayo kuzoba ukuqala kohlaka olusha.
Uma isignali ivela, uhlelo lukala izikhathi zokushaya kanye nezikhathi zekhefu phakathi kwazo futhi lugcina imiphumela ngohlelo kuze kube isikhawu esilandelayo esingu-8- millisecond noma kuze kutholwe izilinganiso ezingama-64. Ngakho, okuwukuphela kwemikhawulo kusilawuli kude (ngokunembe kakhudlwana, ikhodi eyikhiqizayo) leyo divayisi 'engayifunda' ubude besikhathi sokushaya kwenhliziyo ngakunye kanye nokuphumuza, okumele kube ngaphakathi kwemikhawulo ebalulwe ngenhla, kanye nobude obuphelele ikhodi - 32 pulses (kanye 32 ikhefu). Isici esibalulekile ekhonweni ledivayisi lokukhumbula ikhodi imvamisa yokushintshwa kwesiginali ye-IR - isilawuli kude ngasinye sithumela amakhodi ngefrikhwensi yenkampani yenethiwekhi egxilile. Edume kakhulu, ejwayeleke kakhulu yi-36 kHz. Uma kudingeka, umamukeli angashintshwa ngomunye ofanayo ngefrikhwensi yenkampani yenethiwekhi ehlukile. Lokhu kungaba, ngokwesiboneloample, TSOP4833 – 33 kHz, TSOP4838 – 38 kHz, TSOP4840 – 40 kHz.
Lokhu kushintsha kuhlanganisa izinkinobho ezicindezelayo ezivumela ukushintsha okuqondile kwama-relay ngaphandle kwesidingo sokusebenzisa isilawuli kude. Cindezela inkinobho kafushane ukuze uguqule isimo se-relay. Ama-Diodes LED1-LED4 abonisa ukuthi iyiphi i-relay evuliwe okwamanje, kuyilapho i-LED5 isebenza njengedivayisi yokubonisa, ebonisa ukusebenza kwedivayisi, ukwamukela imiyalo ovela kusilawuli kude, kanye nokungena kumodi yokuhlela. Imodi yokuhlela yekhodi yesilawuli kude ivulwa ngokucindezela inkinobho ekhethiwe cishe imizuzwana emi-5. Uma lokhu sekwenziwe, i-LED ehambisana nesiteshi esihleliwe izoqala ukukhanya kancane. Lokhu kusho ukuthi isekethe ilinde umyalo ovela kusilawuli kude ukuze unikezwe futhi wamukelwe, okuzoba nesibopho sokushintsha i-relay. Ukwamukela okulungile ngedivayisi yekhodi yokulawula kude kuphumela ekukhanyeni kwe-LED isikhathi eside, ngemva kwalokho iphinde ikhanye, okubonisa ukuthi isistimu ilindele ukuvunywa komyalo owamukelwe ngaphambilini.
Bese, ucindezela inkinobho efanayo kusilawuli kude futhi. Uma umyalo ovumelekile usutholakele, inqubo yokuhlela iyaqedwa futhi idivayisi izobuyela ekusebenzeni okuvamile. Ukufaka imodi yokuhlela kungenzeka nganoma yisiphi isikhathi ngesikhathi sokusebenza kwedivayisi futhi kwenziwa ngokuzimela esiteshini ngasinye kwezine.
Ukukhweza nokuqalisa
Umdwebo wokukhweza we-PCB uboniswa kuMfanekiso 2. Kokwengeziwe ungathola ama-PCBamples engasetshenziswa njengamaphaneli angaphambili nangemuva. Imininingwane yokufaka ikhonjisiwe ezithombeni ezifakiwe. Ibhodi lingena endlini ye-Z4 - ubukhulu bayo buyi-74 mm × 145 mm. Ukuhlanganiswa kwe-PCB eyinhloko kujwayelekile futhi akudingi incazelo enemininingwane eyengeziwe. Imikhondo ye-LED kuphela edinga ukugotshwa ukuze ibe ngaphezu kwama-angled micro switch futhi ingaphakelwa ngephaneli yangaphambili. Kungumqondo omuhle ukuxhuma izinkambu ezimbili ze-solder ebhodini elikhulu nezinkambu ezisephaneli elingaphambili. Lokhu kuzovumela amabhodi ukuthi afakwe ngokuphepha endlini. Ukwengeza, ibhodi eliyinhloko linezimbobo ezikhwezwayo ezifakwe ezindaweni eziphakeme ezisendlini ukuze kufakwe izikulufu. Iphaneli yangemuva kungcono ifakwe amasokhethi angu-4 uhlobo lwe-GS-035
Afakwe ngesikulufa esisodwa. Xhuma ibhodi elikhulu (X1, X2, X4, X5) kumasokhethi ashiwo ngenhla usebenzisa izintambo ezincane. 1.5 mm . Lawa amasokhethi angasekelwe phansi futhi avumela ukuxhunywa kwedivayisi enezintambo ezinqanyulwe ngepulaki eliyisicaba. Iphaneli elingemuva liphinde libe nesikhala sokuvula/ukuvala kanye nokuvuleka kwekhebula lamandla. Iswishi kufanele ifakwe kusekethe yekhebula lamandla futhi iphethelo yamahhala ibe yi-screw socket X3. I-fuse yayo itholakala ngaphakathi kwedivayisi futhi ngaphambi kwanoma iyiphi enye indawo, khumbula ukunqamula iyunithi kumapayipi amakhulu. Umthwalo wesiteshi/isokhethi eyodwa kufika ku-150 W.
