Le nkampani iqongelele iminyaka yobuchwepheshe bezobuchwepheshe kuma-chips akhethekile we-MCU kanye nesixhumi esibonakalayo.

1. Umhlahlandlela Wokufaka Isicelo

Ama-relay amancane avame ukusetshenziswa ezinhlelweni ze-elekthronikhi ukulawula ukushintshwa kwesekethe, futhi asebenza kabanzi kumishini yezimboni, amathuluzi, nezinto zikagesi zasendlini. Inhliziyo yamasekhethi okulawula esimanje ngokuvamile ama-computer chips afana nama-MCU, ama-DSP, nama-FPGA. Lawa ma-chip chips awanawo amandla okukhipha anele okulawula ngokuqondile ama-relay amancane futhi angashayelwa SLKORAma-transistors amancane BC817-25, BC848B, BC847B, kanye nama-MOSFET amancane 2N7002E, SL2302S, SL2300, SL3400, SL3402, kanye ne-Darlington arrays ULN2001D, ULN2003NjllN2803A.

Esibonelweni esilandelayo, sizosebenzisa ukushayela kwe-relay encane yamandla aphezulu i-JQC-3FF/12VDC-1ZS (551) ukusuka ku-HF njengesibonelo. Ikhoyili ye-relay ine-voltage elinganiselwe engu-12V, i-voltage yesenzo engu-9V, i-voltage enkulu engu-15.6V, kanye nokumelana nekhoyili okungu-400Ω. Uma inikwa amandla yi-12V, ikhoyili yamanje ingu-30mA. Lapha sizokwethula idizayini yokushayela i-relay encane kusetshenziswa i-BC848B, SL2302, ne-ULN2803AS, ngokulandelana. Uma sithatha i-STM32F030C8T6 MCU njengesibonelo, noma iyiphi iphinikhodi ye-IO inganikeza umkhawulo omkhulu wama-25mA wamanje wokudonsa noma wokudonsela phansi, futhi umkhawulo ophelele wamanje wokudonsa noma wokudonsela phansi kuwo wonke amaphinikhodi e-IO ngu-80mA. Ngakho-ke, lapho usebenzisa izikhonkwane ze-IO, kufanele kube nemajini eyanele. Inani elijwayelekile le-resistor yokudonsela phansi ebuthakathaka yephinikhodi ye-IO ngu-40KΩ. Uma inikwa amandla yi-3.3V, uma iphinikhodi ye-IO ikhipha u-8mA wamanje, izinga eliphezulu lokukhiphayo eliphansi ngu-2.9V, futhi uma iphinikhodi ye-IO idonsa u-8mA wamanje, izinga eliphezulu lokukhiphayo eliphansi ngu-0.4V.

2. Ukusebenzisa SI-LKOR BC847B eya Dogwini

I-voltage ye-collector-emitter (VCEO) ye-BC847B transistor ingu-45V, kanti i-collector current (IC) ingu-100mA. Inzuzo yamanje ye-DC (HFE) isuka ku-200 iye ku-450, kanti amandla kagesi aphezulu wokuqoqa i-emitter ngu-600mV. Amandla okufaka ajwayelekile (CIB) ngu-9pF.

Uma ushayela ikhoyili edluliswayo, i-transistor isebenza kusimo sokunqamuka (ukukhululwa kwe-relay) noma kusimo sokuqhuba (i-relay actuation).

Ngesikhathi soguquko olusuka ku-relay actuation ukuya ekukhululweni, ikhoyili edluliswayo ikhiqiza amandla angemuva e-electromotive (EMF). Amandla agcinwe kukhoyili aphuma ku-freewheeling diode (D) kanye nokumelana ngekhoyili. I-EMF yangemuva iboshelwe ekwehleni kwe-voltage eya phambili engu-0.7V kuyo yonke i-diode, ephansi kakhulu kune-voltage ephukile ye-transistor, ngaleyo ndlela ivikela i-transistor.

Amanani ama-resistors u-R1 no-R2 kumjikelezo kufanele aqinisekise ukuthi i-transistor ingena ngokuthembekile ekugcwaliseni okujulile lapho i-voltage yokufaka ingu-2.9V. Uma kubhekwa i-HFE engu-200 ye-BC847B transistor kanye nedrayivu edluliswayo yamanje engu-30mA, isisekelo samanje (IB) sibalwa njengo-0.15mA (30mA/200). Ukuqinisekisa ukugcwala okujulile, isisekelo samanje sikhuphuka sibe ngu-0.3mA. Uma kucatshangwa ukuthi i-base-emitter voltage (VBE) ingu-0.7V uma i-BC847B transistor igcwele futhi i-voltage ephumayo yezinga eliphezulu ye-STM32F030C8T6 microcontroller (MCU) okungenani ingu-2.9V, i-voltage ngaphesheya kwe-resistor R1 kufanele ibe ngu-2.2V.

I-Resistor R2 yengezwa ekunqamuleni okuthembekile i-BC847B transistor ngaphansi kwezimo ezimbi. Uma i-VBE ingu-0.7V, yamanje idlula ku-R2 ingu-IR2=0.7/22=0.032mA. Ukuqinisekisa ukugcwaliswa kwesikhala okujulile, inani lamanje nge-resistor R1 kufanele libe ngu-IR1=0.3+0.032=0.332mA. Ngakho-ke, inani eliphezulu lokumelana le-R1 liyi-R1=2.2/0.332=6.63KΩ. Ukukhetha i-R1 njengo-3.3KΩ kuqinisekisa ukuthi i-BC847B transistor ingangena ekugcwaleni kwesikhala okujulile ngisho nokuhluka kwepharamitha yengxenye. Ekugcwalisweni okujulile, lapho ukunikezwa kwamandla kungu-12V, i-voltage encane ye-relay drive ingu-11.4V, eyanele ukuqinisekisa ukusebenza okuthembekile kwe-relay.

Isikhathi esingaguquki sokuqhuba singalinganiselwa ngokuthi R=R1|R2=2.9KΩ, kanye ne-RC=2.9KΩ*9pF=26.1pS. Isikhathi senqubo yenguquko sifushane kakhulu!

Lapho i-STM32F030C8T6 MCU ikhipha i-voltage yezinga eliphansi, okungenani engu-0.4V, i-base-emitter voltage ye-BC847B transistor ingaphansi kuka-0.4V, okuqinisekisa ukunqamuka okuthembekile kokukhishwa kokudluliselwa.

Ukuqinisekisa ukuthembeka okuphezulu, kuyanconywa ukunika amandla izimelambi zokudonsela phansi ezibuthakathaka (inani elijwayelekile elingu-40KΩ) lembobo ye-I/O elungiselelwe kusofthiwe ye-STM32F030C8T6 MCU.

3. Ukusebenzisa SI-LKOR SL2302 kuya Dogwini

The SLKOR I-SL2302 iyisiginali encane ye-N-channel MOSFET. I-drain-source voltage (VDS) yayo enkulu ingu-20V, i-voltage yomthombo omkhulu wesango (VGS) ingu-12V, futhi ukumelana nobukhulu obungangeni (RDS(on)) ngu-85mΩ ku-VGS = 2.5V kanye ne-ID = 3.1A. I-threshold voltage (i-VGS(th)) ephezulu yokwenziwa kwesango ngu-1.2V, kuyilapho ubuncane bungu-0.65V. Amandla okufaka ajwayelekile (CISS) angama-300pF.

Lapho i-STM32F030C8T6 ikhipha i-voltage yezinga eliphezulu okungenani engu-2.9V, ithatha u-R1 = 10KΩ no-R2 = 100KΩ, amandla kagesi wesimo esingashintshi esangweni le-SL2302 (VGS D) ibalwa ngokuthi (100/(100+10)* 2.9 = 2.64V. Lokhu kuqinisekisa ukuthi i-SL2302 ihlala isesimweni esithembekile sokuqhutshwa kokugcwala okukhulu. Uma i-super saturation, ukumelana ne-conductivity ye-SL2302 akukho ngaphezu kwama-85mΩ. Uma sicabangela amandla kagesi angu-12V, i-voltage ye-relay drive iseduze kakhulu ne-12V, eyanele ukwenza i-relay actuation ethembekile.

Lapho i-STM32F030C8T6 ikhipha i-voltage yezinga eliphansi, ene-voltage ephezulu engu-0.4V, i-voltage yesango le-SL2302 ingaphansi kuka-0.4V, iqinisekisa ukunqamuka okuthembekile futhi ivumela ukukhululwa okuthembekile kwe-relay.

Isikhathi esingaguquki sokuqhuba singalinganiselwa ngokuthi R = R1|R2 = 9.1KΩ, kanye ne-RC = 9.1KΩ * 300pF = 2.73ns. Isikhathi senqubo yenguquko sifushane kakhulu! Lapho i-relay ishintsha isuka ku-actuation iye ekukhululweni, ikhoyili ikhiqiza amandla angemuva e-electromotive (EMF). Amandla agcinwe kukhoyili aphuma ku-freewheeling diode (D) kanye nokumelana ngekhoyili. I-EMF yangemuva iboshelwe ekwehleni kwe-voltage eya phambili engu-0.7V kuyo yonke i-diode, ephansi kakhulu kune-voltage ephukile ye-MOSFET, ngaleyo ndlela ivikeleke. Ukuze kuqinisekiswe ukuthembeka okuphezulu, kuyanconywa ukunika amandla isibambiso sokudonsela phansi esibuthakathaka (inani elijwayelekile elingu-40KΩ) lembobo ye-I/O elungiselelwe kusofthiwe ye-STM32F030C8T6.

4. Ukusebenzisa SLKOR ULN2803AS ukuze Drive

SI-LKOR I-ULN2803AS ingumshayeli we-NPN Darlington transistor enamashaneli ayisishiyagalombili nama-freewheeling diode akhelwe ngaphakathi. Ilungele ukushayela ama-relay amaningi amancane, ama-miniature stepper motors, ama-solenoid, izinkomba, njll. I-voltage yayo ephezulu yokuphuma ingu-50V, kanti umthamo omkhulu wamanje wokuqoqa esiteshini esisodwa ngu-500mA. I-voltage ephezulu yokugcwala kwe-collector-emitter ingu-1.1V ku-collector current engu-100mA, futhi i-voltage ephezulu yokufaka ingu-2.4V uma i-collector yamanje isebenza ku-200mA. Ubukhulu bamanje bokufakwayo ngu-1.35mA ku-voltage yokufaka engu-3.85V, futhi amandla okufaka okufakwayo aphezulu (CI) ngu-25pF.

I-STM32F030C8T6 isetshenziswa njengesilawuli esikhulu, futhi izimbobo zayo eziningi ze-I/O zingashayela ngokuqondile okokufaka kwe-ULN2803AS. Ubuncane bevolthi yokukhiphayo yeleveli ephezulu ngu-2.9V, futhi amandla okukhipha amandla aphezulu weleveli ephansi ngu-0.4V, ehlangabezana ngokugcwele nezimfuneko zokushayela i-ULN2803AS. Ukuze kuthuthukiswe ukuvikeleka kokuphazamiseka kwe-STM32F030C8T6, isixhasi esingu-560Ω singaxhunywa kuchungechunge phakathi kwembobo ye-I/O nokokufaka kwe-ULN2803AS. Ngokushayela ama-relay amancane, ama-freewheeling diode angaphakathi e-ULN2803AS anikeza amandla anele okuhamba ngamasondo, ngakho ngokuvamile asikho isidingo sokwengeza ama-freewheeling diode engeziwe. Uma kudingeka ukwethembeka okuphezulu kakhulu, ukungeza ama-diode ahlukene e-freewheeling kungacatshangelwa. Isikhathi esijwayelekile sokushintsha se-ULN2803AS sicishe sibe ngu-1μs, futhi ngokushayela ama-relay amancane, asikho esinye isibalo esidingekayo.

Uma kucatshangwa ukuthi ukunikezwa kwamandla ka-12V, i-voltage encane ye-relay drive ngu-10.9V, eyanele ukuze kusebenze ukudluliselwa okuthembekile. Lapho i-STM32F030C8T6 ikhipha i-voltage yezinga eliphansi, ene-voltage ephezulu engu-0.4V, i-ULN2803AS inganqamula ngokuthembekile futhi ikhulule i-relay.

Ukuze kuqinisekiswe ukuthembeka okuphezulu, kuyanconywa ukunika amandla isibambiso sokudonsela phansi esibuthakathaka (inani elijwayelekile elingu-40KΩ) lembobo ye-I/O elungiselelwe kusofthiwe ye-STM32F030C8T6.
