UKUQALISA

XHUMANISA USEBENZISA I-ETHERNET
Indlela elula yokwenza i-GNSSDO yakho isebenze ukuyixhuma kunethiwekhi yakho ye-Ethernet noma imbobo ye-Ethernet kumzila wakho we-broadband:

1. Xhuma i-GNSS uthi. Ngaphakathi kwekhithi yakho ye-GNSSDO, uzothola uthi lwe-L1/ L2/L5 GNSS “UFO”. Inoxhumo lwe-TNC. Sebenzisa intambo ehlinzekiwe ye-TNC- SMA ukuxhuma uthi kuxhumo lwe-GNSSDO GNSS SMA. Qinisekisa ukuthi uthi lubekwe ngokuvikelekile esakhiweni ukuze lungakwazi ukunyakaza futhi lube nokucacile view wesibhakabhaka.
2. Xhuma i-GNSSDO kunethiwekhi yakho ye-Ethernet noma umzila. Sebenzisa intambo ehlinzekiwe ye-CAT-6 Ethernet ukuze uxhume imbobo ye-ETHERNET (PoE) kunethiwekhi yakho noma imbobo ye-Ethernet kumzila wakho. Uma umzila wakho uhlinzeka nge-Power-over-Ethernet (PoE), usulungile! Kufanele ubone ukukhanya kwe-LED yamandla abomvu (i-PWR) futhi umbhalo uqala ukuvela kusibonisi se-OLED. Uma umzila wakho unganikezi nge-PoE, qhubekela esinyathelweni sesi-3.
3. Nikeza amandla. Unganika amandla i-GNSSDO usebenzisa i-USB enikeziwe (ishaja yodonga lokudiliva amandla angu-5V). Xhuma ugesi odongeni. Sebenzisa ikhebula le-USB-C elinikeziwe ukuze uxhume ugesi ku-CONFIG MOSAIC noma imbobo ye-CONFIG ESP32 USB-C. Akusho lutho. Kufanele ubone ukukhanya kwe-LED yamandla abomvu (PWR) futhi umbhalo uqala ukuvela kusibonisi se-OLED. Uma i-mosaic-T isithole isignali yesathelayithi futhi ixhunywe kunethiwekhi ye-Ethernet, i-OLED izobonisa: indawo yothi njengoLatitude (Lat), Longitude (Long); ikheli lenethiwekhi ye-Ethernet IP (Internet Protocol); nolunye ulwazi.
4. Xhuma ikhompuyutha yakho, ithebhulethi noma ifoni kunethiwekhi efanayo, vula a web isiphequluli bese uzulazula uye ekhelini le-IP eliboniswe kusibonisi se-OLED. Kufanele ubone ingaphakathi le-mosaic-T web ikhasi. I web ikhasi libonisa ulwazi oluningi oluwusizo futhi lingasetshenziswa ukulungisa ngokugcwele i-mosaic-T.

XHUMA USEBENZISA I-USB-C

I-mosaic-T inembobo ye-USB eyakhelwe ngaphakathi enesivinini esiphezulu esekela i-Ethernet-over-USB. Ukuthatha i-advantage yalesi interface, udinga kuqala ukufaka abashayeli Septentrio.

1. Xhuma uthi lwe-GNSS. Ngaphakathi kwekhithi yakho ye-GNSSDO, uzothola uthi lwe-L1/L2/L5 GNSS “UFO”. Inoxhumo lwe-TNC. Sebenzisa ikhebula le-TNC-SMA elihlinzekiwe ukuxhuma uthi kuxhumo lwe-GNSSDO GNSS SMA. Qinisekisa ukuthi i-antenna igxunyekwe ngokuvikelekile esakhiweni ukuze ingakwazi ukunyakaza futhi ibe nokucacile view wesibhakabhaka.
2. Landa futhi ufake i-SeptentrioRxTools.RxTools ihlanganisa umshayeli wembobo ye-USB-C kanye namathuluzi amaningana ongawasebenzisa ukulawula nokumisa i-mosaic-T, idatha yokudlulisela phambili, idatha yelogi, ukuhlaziya ilogu. files, guqula ilogi files kwamanye amafomethi, futhi ulungiselele imojuli ukuze isetshenziswe namanye ama-software e-GIS.
3. Xhuma i-GNSSDO kukhompyutha yakho. Sebenzisa ikhebula le-USB-C elihlinzekiwe ukuze uxhume imbobo ye-CONFIG MOSAIC kukhompyutha yakho.
4. Vula i-mosaic-T web ikhasi. Vula a web isiphequluli kukhompyutha yakho bese uzulazula uye ku-192.168.3.1 ukuze view i-mosaic-T yangaphakathi web ikhasi.

Manje ungasebenzisa i-RxTools suite ukuthatha i-advan epheleletage ye-mosaic eyinkimbinkimbi-T.

UKULUNGISA I-FIRMWARE

I-GNSSDO iqukethe iphrosesa ye-ESP32-WROVER ekwazi ukulawula ukuvama kwe-crystal oscillator yangaphakathi ye-SiT5358 elawulwa izinga lokushisa. Ngokuxhumanisa imbobo ye-CONFIG ESP32 USB-C kukhompyutha yakho, ungakwazi view futhi uguqule izilungiselelo ze-firmware ye-ESP32 usebenzisa i-terminal emulator.

1. Xhuma uthi lwe-GNSS. Ngaphakathi kwekhithi yakho ye-GNSSDO, uzothola uthi lwe-L1/L2/L5 GNSS “UFO”. Inoxhumo lwe-TNC. Sebenzisa ikhebula le-TNC-SMA elihlinzekiwe ukuxhuma uthi kuxhumo lwe-GNSSDO GNSS SMA. Qinisekisa ukuthi uthi lubekwe ngokuvikelekile esakhiweni ukuze lungakwazi ukunyakaza futhi lube nokucacile view wesibhakabhaka.
2. Xhuma ku-CONFIG ESP32 USB port. Ukuze ulungise izilungiselelo ze-firmware ye-ESP32, udinga ukuxhuma ikhompuyutha embobeni ye-CONFIG ESP32 USB-C futhi usebenzise Itheminali ye-Serial ukushintsha izilungiselelo. Ungase udinge ukufaka umshayeli kuqala, ukuze i-chip ye-serial interface ye-CH340 yaziwe. Sicela ulandele amakhodi e-QR angezansi ukuze uthole imininingwane eyengeziwe:Abashayeli be-CH340

   Isikhathi seTera

   https://learn.sparkfun.com/tutorials/terminal-basics
3. Vula i-Serial Terminal. Uma usebenzisa iWindows, sisancoma i-Tera Term serial terminal kodwa ziningi ezinye izindlela. Sicela ubheke okokufundisa kwethu kwe-Serial Terminal Basics ukuze uthole imininingwane eyengeziwe. Vula uxhumano ku-CH340 usebenzisa i-115200 baud.
4. Sebenzisa Amamenyu ukuze uguqule Izilungiselelo. Uma uvule Itheminali Ye-serial, kufanele ubone imilayezo yokuxilonga esuka ku-firmware iskrola phezulu esikrinini. Shaya noma yimuphi ukhiye kukhibhodi yekhompyutha yakho ukuze uvule imenyu.

Izilungiselelo ze-firmware zigcinwa kumemori ye-flash (engaguquguquki) uma uphuma kumamenyu. Ngemva kokuwashintsha, phuma kumamenyu ngokuphelele, ngemva kwalokho ungakwazi ukunqamula ikhompuyutha futhi unike amandla i-GNSS usebenzisa ishaja yodonga enikeziwe.

Akufanele neze udinge ukushintsha iningi lezilungiselelo ze-firmware, izilungiselelo ezizenzakalelayo zizohlangabezana nezidingo cishe zabo bonke abasebenzisi. Nokho, inketho eyodwa ongase ufune ukuyishintsha “i-TCP Server (IPS1)”. Lokhu kukhutshaziwe ngokuzenzakalela. Uma inikwe amandla, ikuvumela ukuthi ufinyelele ikhonsoli ye-firmware nge-TCP - nge-Ethernet noma i-Ethernet-over-USB - esikhundleni se-CONFIG ESP32 Serial. I-Tera Term inokusekelwa kwe-TCP/IP eyakhelwe ngaphakathi:

I-Common Gotchas

• Ukunemba okuphezulu kwe-GNSS kusebenza kuphela ngama-multi-frequency antennas. Lokhu kusho ukuthi i-antenna ye-GPS owayithola ekuqaleni kwawo-2000 nge-TomTom yakho ngeke isebenze. Sicela usebenzise uthi lwe-SparkFun L1/L2/L5 olunikezwe kukhithi ye-GNSSDO.
• Ukunemba okuphezulu kwe-GNSS kusebenza kahle ngokucaca view kwesibhakabhaka; ayisebenzi endlini noma eduze kwefasitela. Ukusebenza kwe-GNSS ngokuvamile akuthintwa amafu noma iziphepho. Izihlahla namabhilidi angehlisa izinga lokusebenza kodwa ngokuvamile kuphela kuma-canopies aminyene kakhulu noma eduze kakhulu nezindonga zesakhiwo ezinde. Ukwamukelwa kwe-GNSS kungenzeka kakhulu ezikhungweni zasemadolobheni eziminyene ezinezakhiwo eziphakeme kodwa i-RTK enembayo ephezulu ingase ingenzeki.
• Indawo ebikwe idivayisi ye-GNSS iyindawo yesici se-antenna ngokwayo. I-Latitude kanye ne-Longitude kulula ukuzithola kodwa uma uthwebula i-Altitude qiniseka ukuthi ufunda okwengeziwe kuma-ARP (Antenna Reference Points) nokuthi ulandisa kanjani ngobude be-antenna ngaphezu komhlabathi kusofthiwe yakho yokuqoqa idatha.
• I-mosaic-T igodle ikheli le-IP (Internet Protocol) le-subnet 3 yesixhumi esibonakalayo se-USB-C; lokhu akukwazi ukushintshwa. Uma inethiwekhi yakho ye-Ethernet isebenzisa i-subnet 3 (192.168.3.nnn), i-mosaic-T ingase ibonakale inekheli le-IP elivumelekile kodwa ukuxhumana kuzohluleka. Sicela uguqule ukucushwa Komzila wakho ukuze usebenzise i-subnet ehlukile.

imibuzo ejwayelekile ukubuzwa

• Q: Yini okufanele ngiyenze uma i-LED yamandla abomvu ingakhanyi?
  • A: Hlola uxhumo lwamandla futhi uqinisekise ukuthi ukunikezwa kwamandla kusebenza kahle. Zama ukusebenzisa i-outlet yamandla ehlukile noma ikhebuli.
• Q: Ngingayixazulula kanjani inkinga uma uthi lungakutholi isignali yesathelayithi?
  • IMPENDULO: Qinisekisa ukuthi i-antenna ifakwe ngendlela ecacile view wesibhakabhaka. Hlola uxhumo lwe-antenna namakhebuli nganoma yiziphi izinkinga.
