Ha tlhoko ea lihlahisoa tsa theknoloji ea IOT ho tsoa ho bareki ba bacha le ba khale maemong a kopo ea IOT e ntse e eketseha, ho latela litlhoko tsa mmaraka le ka tšebelisano e tebileng lipakeng tsa DTECH le balekane ba maano, DTECH e ntlafalitse ka botlalo lihlahisoa tse teng tsa LORA tse se nang mohala ho theknoloji ea IOT TPUNB. lihlahisoa.
TPUNB (Techphant Ultra-Narrow Band), e le theknoloji ea morao-rao ea puisano ea IOT, e lebisa tšimo ea IOT boemong bo bocha ba nts'etsopele ka melemo ea eona e ikhethang ea tekheniki le likarolo tse ncha.
Ka 2024,DTECH USB/RS232/485 ho isa TPUNB4km radio transmission data transmission radio DTU e sa tsoa qalisoa.E sebelisoa ho rarolla mathata a lebelo le liehang la phetisetso, sebaka se sekhuts'oane sa phetisetso le palo e nyane ea li-byte tsa phetiso ea lihlahisoa tsa mantlha tsa LORA.
1. Ke hobane'ng ha u khetha theknoloji ea TPUNB IOT?
Theknoloji ena e sebelisa lisebelisoa tsa marang-rang tse kang liteishene tsa motheo tsa TPUNB, li-gateways, le li-modules ho haha marang-rang a sireletsehileng a IOT maemong a sa tšoaneng a sebelisa mekhoa e mengata ea marang-rang ho finyella likhokahano tsa tšebeliso ea matla a tlaase bakeng sa palo e kholo ea li-terminals tsa ho lemoha ka har'a marang-rang. kgaso.E na le litšoaneleho tsa ts'ireletso e phahameng, ho hanyetsa tšitiso e matla, concurrency e ngata, theko e tlaase, le ho tsamaisoa habonolo.E ka sebelisoa haholo mafapheng a mangata joalo kalitoropo tse bohlale, lirapa tsa boikhathollo tse bohlale, matla a bohlale, le Marang-rang a Lintho a indasteri.
2. Ke litšobotsi life tsa DTECH USB/RS232/485 ho TPUNB 4km wireless data transmission radio DTU?
1) sebaka se selelele sa limithara tse 4000, phetiso e se nang litšitiso
Phano e phahameng, kutloisiso e phahameng ea ho amohela, le bokhoni bo matla haholo ba ho kenella leboteng.Ha e le sebaka se le seng, ha e bapisoa le lihlahisoa tsa LORA, e ka fetisa lintlha tse ngata 'me lebelo la phetisetso le potlakile.Ka nako e ts'oanang, palo ea data e ke ke ea lahleheloa ke lipakete, e rarollang bothata ba data e nyenyane ea LORA bakeng sa phetisetso ea nako e telele, bothata ba ho lahleheloa ke pakete.
2) Jala hole, hasana ho feta, hasana kapele
Tlhophiso e tloaelehileng e ke ke ea fihlela feela puisano e tloaelehileng ea 4km, empa hape e netefatsa phetiso ea data ea 1280-byte (ntle le lipakete tsa buffering) mme sekhahla sa moea se ka fihla ho 76.8kbps, e ka sebetsanang habonolo le lits'ebetso tse tlase tsa latency, chelete e phahameng le maemo a mangata. .
3) Tlhophiso e se nang mohala, ho ikamahanya le maemo ho ikamahanyang le maemo
Ha ho na moeli ho palo ea li-terminals tse amanang le sehlahisoa.Boema-kepe ba RS485 bo ka hokela lisebelisoa tse 256 mme boema-kepe ba RS232 bo ka hokela sesebelisoa se le seng..RS485 le RS232 li ka fetisa data ka nako e le 'ngoe.Phetiso ea mahlakore a mabeli e sebelisa theknoloji ea phetisetso ea mela ho netefatsa hore data ha e lahleheloe ke lipakete.
4) Moralo oa plug o foufetseng, ha ho hlokahale ho khetholla pakeng tsa ho romela le ho amohela
Sehlahisoa se ts'ehetsa mesebetsi ea transceiver ea li-wireless point-to-point, point-to-multipoint, le multipoint-to-multipoint wireless transceiver.Ha e behe moeli oa hore na ke sefe se fetisang molaetsa kapa moamoheli.E loketse haholo bakeng sa basebetsi ba tlhokomelo 'me e fetoha habonolo ebile e sebelisoa haholo.E sebelisoa haholo ho lokisa liphoso.
5) Mefuta e mengata ea lisebelisoa
① Temo e bohlale:Tlhokomelo ea nako ea 'nete ea mocheso, mongobo, leseli, mobu, pH, joalo-joalo, ho boloka nako le boiteko, le ho tsamaisa tsamaiso.
② Taolo ea indasteri:Ha ho na tlhoko ea lithapo tse boima, RS485/232 e ka ntlafatsoa habonolo ntle le waelese, ea ntlafatsa ts'ebetso le taolo ea bonolo.
③ Ho bala limithara tse bohlale:Ha ho na tlhoko ea ho bala metara khafetsa, pokello e bohlale ea metsi, motlakase le lintlha tse ling ho ntlafatsa ts'ebetso le ho tsamaisa taolo.
DTECH USB/RS232/485 to TPUNB 4km wireless data transmission radio DTU e sa tswa thakgolwa.E tlatsa lekhalo la tekheniki 'marakeng mme e fana ka tharollo e sebetsang le e bonolo ea phetisetso ea data bakeng sa liindasteri tse fapaneng.
