Pambuyo pa zaka zingapo za ntchito yopindulitsa, adaganiza zobweretsa kwa anthu mankhwala athu oyamba owongolera nyengo m'nyumba yanzeru - thermostat yanzeru yowongolera pansi pamoto.
Kodi chipangizochi ndi chiyani?
Ichi ndi chotenthetsera chanzeru chapansi chilichonse chamagetsi chotenthetsera mpaka 3kW. Imayendetsedwa kudzera pa pulogalamu, tsamba lawebusayiti, HTTP, MQTT, kotero imaphatikizidwa mosavuta mumayendedwe onse anzeru apanyumba. Tidzapanga mapulagini odziwika kwambiri.
Simungathe kulamulira pansi pamoto wamagetsi, komanso mutu wotentha wamadzi otentha pansi, boiler kapena sauna yamagetsi. Komanso, pogwiritsa ntchito nrf, thermostat imatha kulumikizana ndi masensa osiyanasiyana. Pafupifupi masensa onse okhudzana ndi nyengo akukula. Popeza chipangizochi chimachokera ku ESP, tinaganiza kuti sikungakhale koyenera kuchotsa zosankha zomwe anthu amagwiritsa ntchito. Chifukwa chake, tidzapanga kuti wogwiritsa ntchito asinthe chipangizocho kuti asinthe ndikuyika firmware ina, mwachitsanzo, mothandizidwa ndi HomeKit kapena ma projekiti ena.
* mutakhazikitsa firmware ya chipani chachitatu mothandizidwa ndi HomeKit kapena mapulojekiti ena otchuka, kubwereranso koyambirira sikutheka kudzera pa OTA (Over-the-Air).
Zovuta zomwe tidakumana nazo
Kunena kuti kunalibe kukanakhala kupusa. Ndiyesera kufotokoza mavuto ovuta kwambiri omwe anabuka ndi momwe tinawathetsera.
Kukhala ndi chipangizocho kunali kovuta. Zonse zokhudzana ndi ndalama zothandizira komanso ndalama za nthawi (zinapangidwa pafupifupi chaka chimodzi).
Panali zambiri zomwe mungasankhe pamsika. Ndipo chodziwika kwambiri ndi kusindikiza kwa 3D. Tiyerekeze:
Classic 3D kusindikiza. Ubwinowo umasiya kukhala wofunidwa, monganso kuthamanga kwa kupanga. Tidagwiritsa ntchito zosindikiza za 3D popanga ma prototypes, koma sizinali zoyenera kupanga.
Photopolymer 3D printer. Apa khalidweli liri bwino kwambiri, koma zotsatira zamtengo wapatali zimabwera. Ma prototypes omwe amasindikizidwa pa printer yofananayo amawononga pafupifupi ma ruble 4000, ndipo iyi ndi gawo limodzi mwa magawo awiri. Mukhoza kugula chosindikizira chanu, chomwe chidzachepetsa mtengo, komabe mtengo udzakhala wa zakuthambo, ndipo liwiro lidzakhala losasangalatsa.
Kujambula kwa silicone. Tinaona kuti iyi ndi njira yabwino kwambiri. Ubwino unali wabwino, mtengo wake unali wokwera, koma osati wovuta. Gulu loyamba lamilandu 20 lidalamulidwa kuti liyesedwe kumunda.
Koma mwayi unasintha zonse. Madzulo ena, ndinayika mwangozi muzokambirana zamkati kwa omanga kuti panali vuto ndi milandu, mtengo unali wokwera kwambiri. Ndipo tsiku lotsatira, mnzake adalemba muuthenga wake kuti mnzake wa mnzakeyo anali ndi TPA (makina a thermoplastic). Ndipo pa gawo loyamba mukhoza kupanga nkhungu kwa izo. Uthengawu udasintha chilichonse!
Ndinaganizirapo kugwiritsa ntchito makina opangira jakisoni m'mbuyomu, koma zomwe zidandiletsa sikunali kufunika koyitanitsa mtanda wa zidutswa za 5000 (ngakhale mutayesa, mutha kupeza zochepa kudzera ku China). Mtengo wa nkhungu unandiyimitsa. Pafupifupi $5000. Sindinali wokonzeka kulipira ndalama imeneyi nthawi imodzi. Kuchuluka kwa nkhungu kudzera mwa mnzathu yemwe wangopanga kumene sikunali zakuthambo, zimasiyana pafupifupi $2000-$2500. Kuwonjezera apo, anavomera kukumana nafe ndipo tinagwirizana kuti malipiro aziperekedwa pangβonopangβono. Choncho vuto la zikopa linathetsedwa.
Vuto lachiwiri komanso lofunikira lomwe tidakumana nalo linali hardware.
Chiwerengero cha kukonzanso kwa hardware sikungathe kuwerengedwa. Malinga ndi kuyerekezera kosamala, njira yomwe yaperekedwa ndi yachisanu ndi chiwiri, osawerengera zapakati. Mmenemo tinayesetsa kuthetsa zofooka zonse zomwe zadziwika panthawi yoyesera.
Chifukwa chake, m'mbuyomu ndidakhulupirira kuti panalibe chifukwa choyang'anira zida zamagetsi. Tsopano, popanda izo, chipangizocho sichidzapanga kupanga: chifukwa cha capriciousness ya nsanja yomwe tasankha.
Kuyika kwina kwa analogi ku ESP. M'mbuyomu ndimaganiza kuti pini iliyonse ya ESP inali yapadziko lonse lapansi. Koma ESP ili ndi pini imodzi yokha ya analogi. Ndinaphunzira izi pochita, zomwe zinayambitsa kukonzanso ndi kukonzanso matabwa adera osindikizidwa.
Mtundu woyamba wa matabwa osindikizidwa
Mtundu wachiwiri wa matabwa osindikizidwa
Mtundu wa penultimate wa matabwa osindikizidwa, pomwe tidayenera kuthana ndi mavuto mwachangu ndi pini ya analogi.
Ponena za mapulogalamu, panalinso misampha yambiri.
Mwachitsanzo, ESP imagwa nthawi ndi nthawi. Ngakhale ping imapitako, tsamba silimatseguka. Pali njira imodzi yokha - kulembanso laibulale. Pakhoza kukhala ena, koma zonse zomwe tidayesera sizinagwire ntchito.
Vuto lalikulu lachiwiri, modabwitsa, ndi kuchuluka kwa zopempha ku ESP potsegula tsamba. Pogwiritsa ntchito GET kapena ajax, tidayang'anizana ndi mfundo yoti kuchuluka kwa zopempha kudakula mopanda ulemu. Chifukwa cha izi, ESP idachita mosayembekezereka, imatha kungoyambiranso kapena kukonza pempholo kwa masekondi angapo. Yankho lake linali kusinthana ndi ma sockets. Zitatha izi, chiwerengero cha zopempha chinachepa kwambiri.
Vuto lachitatu ndi mawonekedwe a intaneti. Zambiri za izo zidzakhala m'nkhani ina yomwe idzasindikizidwa mtsogolo.
Pakalipano ndingonena kuti njira yabwino kwambiri panthawiyi ndikugwiritsa ntchito VUE.JS.
Chimango ichi ndi choyenera kwambiri pa zonse zomwe taziyesa.

Kukhala thermostat
Titagonjetsa zovuta zonse, tapeza zotsatirazi:
Ntchito yomanga
Thermostat imakhala ndi matabwa atatu (ma module):
- Woyang'anira;
- Yoyendetsedwa;
- Chiwonetsero cha bolodi.
Π£ΠΏΡΠ°Π²Π»ΡΡΡΠ°Ρ - bolodi yomwe ESP12, hardware "watchdog" ndi nRF24 zilipo kuti zigwire ntchito ndi masensa amtsogolo. Poyambitsa, chipangizochi chimathandizira DS18B20 digito sensor. Koma tidapereka mwayi wolumikiza masensa a analogi kuchokera kwa opanga gulu lachitatu. Ndipo mu imodzi mwazosintha zamtsogolo zamapulogalamu tidzawonjezera kuthekera kogwiritsa ntchito masensa omwe amabwera ndi ma thermostats a chipani chachitatu.
Zoyendetsedwa - bolodi lamagetsi ndi katundu wowongolera. Kumeneko adayika magetsi a 750mA, ma terminals olumikizira masensa a kutentha ndi 16A relay kuti athe kuwongolera katundu.
kuwonetsera - pa gawo lachitukuko lomwe tasankha Mainchesi 2.4.
Mutha kupeza mosavuta zambiri za izo pa intaneti. Ndikufuna kuwonjezera kuti ndi yabwino kwa pafupifupi aliyense, kupatulapo mtengo. Chiwonetsero cha 2.4-inch chimawononga pafupifupi 1200 β½, zomwe sizikhala ndi zotsatira zabwino pamtengo womaliza.
Chifukwa chake adaganiza zopanga analogue kuti agwirizane ndi zosowa zathu, koma pamtengo wotsika. Zowona, muyenera kuyikonza mwanjira yachikale, osati kuchokera ku Nextion Editor. Ndizovuta kwambiri, koma ndife okonzeka.
Analogue idzakhala matrix a 2.4-inch okhala ndi chophimba chokhudza komanso bolodi yokhala ndi STM32 m'bwalo kuti muwongolere ndikuchepetsa katundu pa ESP12. Ulamuliro wonse udzakhala wofanana ndi Nextion kudzera UART, komanso 32 MB kukumbukira ndi zonse kung'anima khadi yojambulira zipika.
Mapangidwe a modular amachititsa kuti zikhale zosavuta kusintha ma modules ndipo zotsatira zake ndi chipangizo chosiyana kwambiri.
Mwachitsanzo, palinso zosankha za "board 2" m'mitundu ingapo:
- Zosankha 1 - kwa pansi pamoto. Mphamvu yochokera ku 220V. Relay imayendetsa katundu aliyense pambuyo pake.
- Zosankha 2 - pamadzi otentha pansi kapena valavu ya batri. Mothandizidwa ndi 24V AC. Kuwongolera kwa mavavu kwa 24V.
- Zosankha 3 - magetsi kuchokera ku 220V. Kuwongolera kwa mzere wosiyana, monga boiler kapena sauna yamagetsi.
Pambuyo pake
Ine sindine katswiri wopanga. Ndinakwanitsa kugwirizanitsa anthu ndi cholinga chimodzi. Kwa mbali zambiri, aliyense amagwira ntchito pa lingaliro; kuti achite chinthu chofunika kwambiri; chinthu chomwe chingakhale chothandiza kwa wogwiritsa ntchito.
Ndine wotsimikiza kuti anthu ena sangakonde kamangidwe ka mlanduwo; kwa ena - mawonekedwe a tsamba. Ndi ufulu wanu! Koma ife tinapita njira yonseyi tokha, kupyolera mukutsutsa kosalekeza kwa zomwe tikuchita, ndipo chofunika kwambiri, chifukwa. Ngati mulibe mafunso ngati omwe tawatchulawa, tidzakhala okondwa kucheza mu ndemanga.
Kudzudzula kolimbikitsa nβkwabwino, ndipo timayamikira kwambiri.
Mbiri ya lingaliro . Kwa omwe ali ndi chidwi:
- Pamafunso onse: Gulu la Telegraph
- Tsatirani nkhani: Njira yodziwitsa za Telegraph
Inde, timasangalala ndi zimene timachita.
