Sezvo kudiwa kwezvigadzirwa zvetekinoroji zveIOT kubva kune vatsva nevatengi vekare muIOT application mamiriro ezvinhu kuri kuramba kuchiwedzera, mukupindura zvinodiwa nemusika uye nekubatana kwakadzama pakati peDTECH nevadyidzani vane hunyanzvi, DTECH yakakwidziridza zvizere zvigadzirwa zveLORA zviripo zvisina waya kuIOT TPUNB tekinoroji. zvigadzirwa.
TPUNB (Techphant Ultra-Narrow Band), seyekucheka-kumucheto IOT yekutaurirana tekinoroji, iri kutungamira iyo IOT ndima kune imwe nhanho yebudiriro ine yakasarudzika tekinoroji mabhenefiti uye hunyanzvi maficha.
Muna 2024,DTECH USB/RS232/485 kuenda kuTPUNB4km isina waya data transmission radio DTU ichangobva kutangwa.Iyo inoshandiswa kugadzirisa matambudziko ekunonoka kutapurirana kumhanya, kupfupika kwekutapurirana chinhambwe uye diki nhamba yemabheti ekutapurirana ezvigadzirwa zveLORA zvepakutanga.
1. Sei uchisarudza tekinoroji yeTPUNB IOT?
Iyi tekinoroji inoshandisa network element midziyo yakaita seTPUNB base zviteshi, magedhi, uye mamodules kuchinjika kuvaka yakachengeteka IOT yakavanzika network munzvimbo dzakasiyana siyana uchishandisa akawanda networking nzira kuti uwane ekupedzisira-akaderera mashandisiro emagetsi ekubatanidza kune yakakura nhamba yekunzwa terminals mukati metiweki. coverage.Iine maitiro ekuchengetedza kwepamusoro, kuramba kupindira kwakasimba, concurrency yakawanda, mutengo wakaderera, uye nyore kutumira.Inogona kushandiswa zvakanyanya munzvimbo dzakawanda dzakadai semaguta akangwara, mapaki akangwara, simba rakangwara, uye maindasitiri Internet eZvinhu.
2. Ndeapi maitiro eDTECH USB/RS232/485 kusvika TPUNB 4km wireless data transmission radio DTU?
1) 4000 metres kureba, chipingamupinyi-isina kutapurirana
Kuwana kwepamusoro, kugashira kwakanyanya, uye kugona kwakasimba kwemadziro ekupinda.Pachinhambwe chimwechete, zvichienzaniswa nezvigadzirwa zveLORA, inogona kufambisa data rakawanda uye kumhanya kwekutapurirana kunokurumidza.Panguva imwecheteyo, chiyero che data hachizorasikirwi nemapakiti, izvo zvinogadzirisa dambudziko reLORA shoma shoma yedheta yekufambisa kure-kure, dambudziko rekurasikirwa kwepakiti.
2) Kupararira kure, kupararira zvakanyanya, kupararira nekukurumidza
Iyo yakajairwa gadziriso haingogone kuwana 4km yakajairika kutaurirana, asi zvakare inovimbisa 1280-byte data kutapurirana (pasina buffering mapaketi) uye mwero wemhepo unogona kusvika 76.8kbps, iyo inogona nyore kurarama ne-low-latency, high-concurrency uye akawanda-scenario application. .
3) Wireless parameter kumisikidzwa, yakangwara inogadzirisa yekuzvienzanisa
Iko hakuna muganhu pahuwandu hwematerminals akabatanidzwa kune chigadzirwa.Iyo RS485 port inogona kubatana ne256 zvishandiso uye iyo RS232 port inogona kubatana kune 1 mudziyo..RS485 uye RS232 inogona kutumira data panguva imwe chete.Iyo bidirectional yekufambisa inoshandisa tekinoroji yekufambisa kwemutsara kuona kuti data hairasikirwe nemapaketi.
4) Bofu plug dhizaini, hapana chikonzero chekusiyanisa pakati pekutumira uye kugamuchira magumo
Chigadzirwa chinotsigira point-to-point, point-to-multipoint, uye multipoint-to-multipoint wireless transceiver mabasa.Izvo hazvidzikise kuti ndeupi magumo ari transmitter kana anogamuchira.Iyo yakanakira vashandi vekuchengetedza uye inoshanduka uye inoshandiswa zvakanyanya.Inonyanya kushandiswa mukugadzirisa.
5) Yakasiyana-siyana yekushandisa
① Kurima kwakangwara:Chaiyo-nguva yekutarisa tembiricha, hunyoro, mwenje, ivhu, pH, nezvimwe, kuchengetedza nguva uye kushanda nesimba, uye kufambisa manejimendi.
② Kudzora kwemaindasitiri:Hapana kudikanwa kwekuremedza wiring, RS485/232 inogona kukwidziridzwa zviri nyore isina waya, kuvandudza kugona uye kufambisa manejimendi.
③ Kungwara kwemamita kuverenga:Hapana chikonzero chekugara uchiverenga mita, hungwaru muunganidzwa wemvura, magetsi uye imwe dhata kuti uvandudze mashandiro uye kufambisa manejimendi.
DTECH USB/RS232/485 kusvika TPUNB 4km isina waya data transmission radio DTU ichangobva kutangwa.Iyo inozadza iyo tekinoroji gaka mumusika uye inopa inoshanda uye iri nyore yekufambisa data mhinduro kune akasiyana maindasitiri.
Nguva yekutumira: Mar-27-2024
