2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Conventionally, Wireless-tswj cov neeg hlau siv rf circuits, uas muaj qhov tsis zoo ntawm kev txwv ua haujlwm ntau, txwv ntau zaus thiab txwv kev tswj hwm. Kev siv lub xov tooj ntawm tes rau kev tswj neeg hlau tuaj yeem kov yeej cov kev txwv no. Nws muab qhov zoo ntawm kev tswj hwm muaj zog, ua haujlwm ntau npaum li thaj tsam ntawm cov kev pabcuam, tsis muaj kev cuam tshuam nrog lwm tus tswj thiab mus txog kaum ob tus tswj.

Txawm hais tias qhov pom thiab lub peev xwm ntawm cov neeg hlau sib txawv loj heev, txhua tus neeg hlau sib koom cov yam ntxwv ntawm cov neeg kho tshuab, txav tau raws li qee yam kev tswj hwm. Kev tswj hwm neeg hlau cuam tshuam nrog peb theem sib txawv: kev nkag siab, kev ua thiab kev nqis tes ua. Feem ntau, cov thawj coj yog cov ntsuas hluav taws xob tau teeb tsa ntawm tus neeg hlau, kev ua tiav yog ua los ntawm tus tswj hwm lub tshuab microcontroller lossis tus tsim khoom, thiab txoj haujlwm tau ua tiav los ntawm kev siv lub cav lossis nrog qee tus neeg ua haujlwm. Kuv xav ua kom meej, yog tias koj ntsib teeb meem kuv tsis txaus siab rau koj, koj tuaj yeem sau lus lossis koj tuaj yeem xa ntawv tuaj rau kuv ntawm [email protected]

Kauj Ruam 1: ZOO TSHAJ PLAWS

Hauv txoj haujlwm no tus neeg hlau, tswj hwm los ntawm lub xov tooj ntawm tes uas hu rau lub xov tooj ntawm tes txuas rau tus neeg hlau thaum lub sijhawm hu, yog tias muaj lub pob nyem tau raug tswj raws li lub pob nyem tau hnov ntawm lwm qhov kawg ntawm kev hu. Lub suab no hu ua dual tone multi frequency tome (DTMF) neeg hlau tau txais lub suab DTMF no nrog kev pab ntawm xov tooj sib dhos hauv tus neeg hlau

Lub suab tau txais tau ua tiav los ntawm atmega16 microcontroller nrog kev pab los ntawm DTMF decoder MT8870 tus txiav txim siab txiav suab DTMF lub suab rau nws cov lej sib npaug binary thiab tus lej binary no xa mus rau microcontroller, lub microcontroller tau npaj ua ntej los txiav txim siab rau ib qho muab tswv yim thiab tawm nws qhov kev txiav txim siab rau cov neeg tsav tsheb kom tsav lub cav rau pem hauv ntej lossis rov qab txav lossis tig. Lub xov tooj ntawm tes uas hu mus rau lub xov tooj ntawm tes tau teeb nyob rau hauv tus neeg hlau ua raws li cov chaw taws teeb. Yog li qhov phiaj xwm neeg hlau yooj yim no tsis xav tau kev tsim cov khoom siv thiab cov chaw xa khoom. DTMF kev teeb tsa yog siv rau kev hu xov tooj tshaj kab hauv kab lus hauv lub suab nrov mus rau qhov chaw hloov chaw hu. Qhov DTMF siv rau kev hu xov tooj yog hu ua touch tone. DTMF muab lub sijhawm tshwj xeeb (suav nrog ob lub suab sib cais) rau txhua qhov tseem ceeb uas nws tuaj yeem txheeb xyuas tau yooj yim los ntawm kev siv hluav taws xob. Lub teeb liab tsim los ntawm DTMF tus lej yog qhov xa ncaj qha rau al-gebric, nyob rau lub sijhawm tiag tiag ntawm qhov ntau ntawm ob sine (cosine) nthwv dej ntawm ntau qhov sib txawv, piv txwv li, nias 5 yuav xa lub suab ua los ntawm kev ntxiv 1336hz thiab 770hz mus rau lwm qhov kawg ntawm mobile. Lub suab nrov thiab haujlwm hauv dtmf system qhia hauv qab no

Kauj Ruam 2: Kev piav qhia Circuit

Cov duab qhia pom daim duab thaiv thiab daim duab cicuit ntawm microcontroller-based neeg hlau. Cov khoom tseem ceeb ntawm tus neeg hlau no yog DTMF tus txiav txim siab, Microcontroller thiab tsav tsheb.

Ib qho MT8870 series dtmf decoder tau siv ntawm no. Txhua hom mt8870 series siv cov txuj ci suav suav txhawm rau txhawm rau txheeb xyuas thiab txiav txim siab kaum rau DTMF lub suab sib luag hauv plaub plaub qhov chaws tso tawm. Lub built -in dila tone regection Circuit tshem tawm qhov xav tau rau kev ua ntej lim. Thaum lub teeb liab tawm tswv yim muab rau ntawm tus pin2 (IN-) ib qho xaus kev teeb tsa lub tswv yim tau lees paub kom ua tau zoo, qhov tseeb plaub qhov txiav txim siab teeb liab ntawm DTMF lub suab tau xa mus rau Q1 (pin11) mus txog Q4 (pin14) tawm. Atmega 16 yog lub zog qis, 8 ntsis, cmos microcontroller raws li AVR txhim kho RISC architecture. Nws muab cov hauv qab no: 16kb ntawm qhov system programmable flash memory nrog nyeem ntawv muaj peev xwm, 512bytes ntawm EEPROM, 1KB SRAM, 32 lub hom phiaj dav dav nkag/tso tawm kab. 32 lub hom phiaj ua haujlwm sau npe. Txhua 32 qhov kev sau npe tau txuas ncaj qha mus rau chav lej lej, tso cai rau ob qho kev sau npe ywj pheej kom nkag tau rau hauv ib qho kev qhia teeb liab uas ua tiav hauv ib lub moos. Qhov tshwm sim architecture yog qhov ua tau zoo dua. Cov zis tawm los ntawm cov chaw nres nkoj pins PD0 mus txog PD3 thiab PD7 ntawm lub microcontroller tau pub rau cov tswv yim IN1 txog IN4 thiab pab kom pins (EN1 thiab EN2) ntawm lub tshuab tsav L293d feem, txhawm rau tsav lub zog tsav. Hloov S1 yog siv rau kev rov pib dua phau ntawv. cov cim yog: ic1 - mt8870 ic2 - atmega16 ic3 - l293d ic4 - cd7004 r1, r2 - 100k resistances r3 - 330k resistances r4 -r8 - 10k resistances c1- 0.47 micro farat capacitor c2, c3, c5, c6 - 22pfarat capacitor c4 - 0.1micro farat capacitor xtal1 - 3.57 mhz crytal xtal2 - 12mhz siv lead ua s1 - thawb rau ntawm hloov m1, m2 - 6v 50rpm lub cev muaj zog batt -6v

Kauj Ruam 3: Cov Lus Qhia Software (Hex Code)

lub Avr microcontroller tau teeb tsa siv WIN AVR rau cov pib pib saib qhov kev qhia ua ntej no avratmega 16look ntawm tus pin daim duab ntawm atmega16 thiab tom qab ntawd txuas cov pins acordingly (yog tias koj muaj teeb meem ces xav tias dawb sau kuv) kuv tau txuas tag nrho cov cai. Cov ntaub ntawv header yuav suav nrog yog tias koj tau teeb tsa winavr hauv qhov chaw tsis raug

Kauj ruam 4: Ua haujlwm

Txhawm rau tswj tus neeg hlau, koj yuav tsum tau hu xov tooj ntawm tes txuas nrog tus neeg hlau los ntawm txhua lub xov tooj.

tam sim no lub xov tooj tau xaiv los ntawm lub xov tooj ntawm tus neeg hlau los ntawm hom autowerwer (uas yog hauv phn, tsuas yog pab nws). tam sim no thaum koj nias 2 tus neeg hlau yuav txav mus tom ntej thaum koj nias 4 tus neeg hlau yuav txav mus rau sab laug thaum koj nias 8 tus neeg hlau yuav txav rov qab thaum koj nias 6 tus neeg hlau yuav txav mus sab xis thaum koj nias 5 tus neeg hlau yuav tsum nres.

Kauj Ruam 5: Kev tsim kho

rau kev tsim cov neeg hlau no, koj xav tau cov khoom siv no Cov khoom siv: - "MT8870 DTMF DECODER - 1" Atmega 16 microcontroller - 1 "L293d lub cev muaj zog tsav tsheb ic - 1" Cd7004 tsis qhib ic - 1 "1n4007 diode - 1" 100k resistances - 2 "10 k resistances - 5 "330 k resistances - 1" 0.47mf capacitors - 1 "0.1mf capacitors - 1" 22pf capacitors - 4 "3.57mhz siv lead ua - 1" 12mhz siv lead ua - 1 "Laub rau ntawm qhov hloov - 1" 2 lub zog motors (6v, 50 rpm) - 2 (4 rau plaub lub log tsav) "Roj teeb 6v - 1

• lub log - 4
• xov tooj ntawm tes - 2 (ib xyoos thiab ib tus tuaj yeem yog koj li frnds)
• handsfree - 1 (rau phn ntawm lub rover)

koj yuav tsum tso lub xov tooj ntawm tes ntawm lub rover. Lub xov tooj ntawm tes txuas nrog lub rover los ntawm kev siv tes dawb. tsim lub rover hauv cov duab uas tau muab hauv qab no. Koj tuaj yeem tau txais cov khoom no los ntawm txhua lub khw hluav taws xob yooj yim

Kauj Ruam 6: Txhawm rau Txuas Tes Dawb Nrog Lub Circuit Court

muaj ib txwm muaj ob qhov kev sib txuas uas tawm hauv xov tooj, cov kev sib txuas no yog 1. Ntsis 2. Ntiv nplhaib kuv yuav nyiam siv lub tes dawb uas muaj lub jack ncaj (zoo ib yam li peb siv hauv peb lub ipods, tab sis ib qho me dua) qhov ntxeev ntawm lub jack hu ua "tip" thiab qhov seem tom qab qhov taub tom qab ib daim kab xev dub yog lub nplhaib Yog li txuas ob qhov kev sib txuas no nrog hauv Circuit Court thiab koj yuav ua tiav

Kauj Ruam 7: END

Ua raws li cov theem thiab koj ua tiav. tab sis yog tias koj ntsib teeb meem xav sau ntawv tawm lossis xa ntawv tuaj rau kuv ntawm [email protected]
