Layanan Lokasi GSM modul SIM800x lan karyane karo Yandex.Locator API

Google, sayangé kanggo akeh pangguna modul GSM, 2-3 sasi kepungkur diblokir lan ditransfer menyang basis mbayar API kanggo nemtokake lokasi adhedhasar koordinat menara sel katon modul. Amarga iki, ing SIM800 seri modul diprodhuksi Solusi Nirkabel SIMCom, fungsi printah AT+CIPGSMLOC mandheg. Ing artikel iki, aku bakal menehi pitutur marang kowe carane sampeyan bisa ngatasi masalah iki kanthi nggunakake layanan sing padha sing diwenehake dening Yandex - Yandex.Locator.

Ayo skip carane Yandex nampa koordinat menara sel, sing utama yaiku kita bisa nggunakake layanan gratis iki lan entuk data ing ngisor iki: Latitude, Longitude, Altitude, uga kesalahan perkiraan kanggo saben parameter. Tujuan utama artikel kasebut yaiku kanggo menehi tutorial singkat babagan cepet ngalih menyang API Yandex, tinimbang layanan sing ora kasedhiya saka Google.

Ing ngisor iki, minangka conto, kita bakal nuduhake mung garis lintang lan bujur lokasi modul.

Dadi ayo miwiti

Pisanan sampeyan kudu maca persetujuan pangguna sing ana ing: yandex.ru/legal/locator_api. Perhatian khusus kudu dibayar kanggo klausa 3.6. persetujuan pangguna iki, sing nyatakake Yandex nduweni hak kanggo ngganti / mbenerake utawa nganyari API Yandex.Locator sawayah-wayah, tanpa kabar sadurunge..

Pindhah menyang alamat yandex.ru/dev/locator/keys/get lan tambahake akun Yandex sing wis digawe sadurunge menyang grup pangembangan. Langkah-langkah iki bakal ngidini sampeyan entuk kunci kanggo ngakses layanan iki.

Tulis utawa simpen kunci sing ditampa.

Sawise ngrampungake langkah-langkah kasebut, sampeyan bakal entuk akses menyang kaca kasebut yandex.ru/dev/locator/doc/dg/api/geolocation-api-docpage ing ngendi informasi dhasar babagan mekanisme operasi layanan Yandex.Locator diwenehake.

Kanggo ngasilake panjalukan XML ing format cURL menyang layanan Yandex.Locator, sampeyan kudu entuk informasi babagan menara sel "katon" dening modul:

• kode negara – kode negara
• operatorid – kode jaringan seluler
• cellid - pengenal sel
• lac – kode lokasi

Informasi iki bisa dipikolehi saka modul kanthi ngirim printah 'AT + CNETSCAN'.

Wigati dimangerteni manawa mengko sampeyan kudu ngowahi data saka respon Cellid lan Lac modul saka heksadesimal dadi desimal.

Saiki kita kudu ngasilake data XML kanggo ngubungi server Yandex, sing bakal digabung dadi siji unsur.

Mangkono, kita nampa koordinat modul saiki: 60.0330963, 30.2484304.
Nalika jumlah data sing dikirim liwat menara sel mundhak, akurasi penentuan lokasi bakal saya tambah kanthi proporsional.

kesimpulan

Mugi materi iki bakal bantuan apik kanggo pangembang. Aku siap mangsuli pitakon sampeyan ing komentar.
