Kushanda pamwe chete kweChiteshi Chekuchaja Chekuvhura: Mhinduro yeOCPP Yakazara, Kusimudzira Kugadzika Kwechigadzirwa uye Kukurumidza Kubudirira

Nekukura kuri kuita indasitiri yemagetsi pasi rose, kuvandudzwa kwezvivakwa zvekuchaja zvine hungwaru uye zvakajairwa kwave chinhu chinodiwa nekukurumidza muindasitiri. OCPP (Open Charge Point Protocol), inoshanda se "mutauro wakajairika" unobatanidzanzvimbo dzekuchaja dzemagetsinehurongwa hwehutungamiriri hwepakati, huri kubuda sehunyanzvi hunokosha hwekugadzirisa matambudziko ekushanda pamwe chete kwemidziyo.

I. OCPP: Sei Zvichikosha Kuti Musika weEurope Upinde?

OCPP inzira yekutaurirana yakavhurika uye yakajairika inoita kutinzvimbo dzekuchaja mota dzemagetsi kubva kuvagadziri vakasiyana vanogona kutaurirana zviri nyore nechero system inoenderana ne backend management. Kubatanidza OCPP protocol kunopa zvigadzirwa "standard communication interface," zvichipa kukosha kukuru kuburikidza ne:

Kuputsa Zvipingamupinyi zveKushanda pamwe chete: Inogonesa nzvimbo dzekuchaja kuti dzibatanidzwe nechero puratifomu yekushanda yebato rechitatu inoenderana nezvinodiwa zveOCPP, zvichivandudza kugona kwechigadzirwa;

Kutevedzera Mitemo: Inosangana nezvinodiwa zveEU zvekushanda pamwe chete pakugadzirisa zvivakwa, zvichishanda sechinodiwa kuti pave nekupinda mumusika;

Kuvhura Zvinhu Zvakangwara: Inotsigira kudzora kuri kure, kubhadharisa mari, kutarisa mamiriro ezvinhu, uye kugadzirisa firmware yeOTA, zvichideredza zvakanyanya kuedza kwekugadzira maapplication epamusoro-soro;

Kuderedza Mari Yekubatanidza: Inoshandisa nzira yakajairika yekubatanidza, ichidzivirira kugadzirwa kwemaitiro uye mari yekuchengetedza kwenguva refu inobatanidzwa nemaprotocol emakambani.

II. MicroOcpp: Mhinduro Yakareruka Yakagadzirirwa Zvishandiso Zvakaiswa Mukati

Kune nharaunda dzakabatikana dzine zviwanikwa zvakawanda, MicroOcpp inopa nzira yakanaka yekushandisa OCPP protocol stack ine zvakanakira zvikuru zvinosanganisira:

Nzvimbo ine ruzivo rwakaderera zvakanyanya: Yakanyorwa muC/C++ uye yakagadzirirwa zvakananga ma microcontrollers ne embedded Linux;

Rutsigiro Rwakazara rweProtocol: Inoshanda zvizere neOCPP 1.6 uye inotsigira kuvandudzwa kuenda ku2.0.1;

Kugadzira Modular: Inobvumira kuunganidzwa kwezvinhu zvinodiwa chete kuti zviwedzere kushandiswa kwemidziyo yehardware;

Inoshamwaridzana Nevagadziri: Inopa ma API interfaces akajeka uye mienzaniso yakawanda yezvipingamupinyi zvishoma zvekubatanidza.

III. Maitiro Ekutumira: Kuvaka Sisitimu Yekutaurirana yeOCPP Kubva Pakutanga

1. Kugadzika Kwenzvimbo Yeseva

Shandisai server yeSteVe OCPP nekukurumidza muchishandisa maDocker containers. Senzira yekutarisira central management system yakavhurika, SteVe inopa kugona kwakazara kwekugadzirisa chiteshi chekuchaja, kusanganisira kugadzirisa kutaurirana kweWebSocket, kutarisa mamiriro ekuchaja, uye kuburitsa mirairo yekudzora iri kure.

2. Matanho Akakosha Ekutumira Vatengi

Munguva yekuiswa kweMicroOcpp client papuratifomu yeMYD-YF13X, takashandisa nharaunda yeLinux 6.6.78 system yakapihwa. Kutanga, batanidzai MicroOcpp source library kuti mugadzire ma executable eARM-optimized. Tevere, gadzirai ma GPIO pini kuti mutevedzere mamiriro ekubatanidza pfuti yekuchaja: shandisai maGPIO ports maviri kumiririra status detection yeimwe neimwe charging interface.

3. Kugadzirwa kweKutaurirana pakati peSevha neVatengi

Mushure mekuiswa, mutengi akabudirira kugadzira kubatana kweWebSocket neSteVe server:

Iyo interface yekutarisira sevha yakaratidza iyo ichangobva onlinenzvimbo yekuchaja mota yemagetsimunguva chaiyo, zvichisimbisa kubatana kwakakodzera uye kudyidzana kweprotocol.

4. Kusimbiswa kweBasa reKushuma Mamiriro

Nekushandisa mazinga eGPIO kuti titevedzere kuiswa/kubviswa kwepfuti yekuchaja, tinoona mutengi achishuma shanduko dzemamiriro ezvinhu kuseva munguva chaiyo.

Chishandiso cheseva chinogadzirisa mamiriro econnector nenzira imwe chete, zvichiratidza mashandiro echeni yese yekutaurirana nemazvo.

Sezvo pasi rosenzvimbo yekuchaja yakangwaraMusika uchiramba uchienderana, rutsigiro rweprotocol yeOCPP rwave chinhu chakakosha mukukwikwidzana kwechigadzirwa. Mhinduro yakazara yeOCPP yakapihwa naMir yakavakirwa papuratifomu yeMYC-YF13X haingodzikisi zvakanyanya chiyero chekusimudzira asi zvakare inovimbisa kutevedzera mitemo yechigadzirwa uye kugona kuchinjika pamusika.
