How to test COFDM IP wireless video data transmitter module

How to test the one-way network transparent transmission module?

There are two steps here, the first step is to connect the wireless transmission module to the computer with a network cable, and the second step is to run the network assistant on the computer and configure it correctly.

After configuring the network assistant, send the data string on the computer connected to the transmitting module, and observe whether the network assistant on the computer connected to the receiving module can receive the correct data string.

First of all, you will find that both the transmitter module and the receiver module have a network port. We connect the transmitter module and the receiver module to two computers through network cables.

Nceda uqaphele ukuba zombini iikhompyutha kufuneka zisetwe kwicandelo elinye lothungelwano, njenge 192.168.1.xxx.

Emva koko sebenzisa umncedisi womnatha kwikhompyuter kwaye uyiqwalasele ngokuchanekileyo. Eli nyathelo libaluleke kakhulu.

1. Fumana iiPC ezimbini, qwalasela iidilesi ze-IP ezingatshintshiyo, kwaye uqinisekise ukuba iiPC zombini zikwicandelo elinye lothungelwano (umzekelo, 192.168.0.90 kwaye 192.168.0.215).
2. IiPC ezimbini ziqhagamshelwe ngokulandelelana kwisiphelo sokuthumela kunye nesiphelo sokufumana ikhonkco lendlela enye ye-cofdm yokuhambisa elubala. (umzekelo, i-PC IP eqhagamshelwe kwisiphelo sothumelo yi 192.168.0.90, kunye nePC IP eqhagamshelwe kwisiphelo sokufumana 192.168.0.215)
3. Qhuba i “I-NetAssist V5.0.8” isoftware kwiPC eqhagamshelwe kwi-transmitter, kwaye uyiqwalasele njengendlela yokuthumela ye-UDP (usasazo, indawo yokufikela: 8090), Njengoko kubonisiwe ngezantsi:

4. KwiPC eqhagamshelwe kwisiphelo sokufumana, qhuba i “NetAssist” isoftware kwaye uyiqwalasele njengemowudi yokufumana i-UDP (Izibuko lendawo: 8090), Njengoko kubonisiwe ngezantsi:

5. I-PC eqhagamshelwe kwisiphelo sothumelo ithumela idatha, kwaye kwimeko yoqhagamshelwano olungenazingcingo, iPC eqhagamshelwe kwisiphelo sokufumana iya kufumana idatha ethunyelwe yiPC ekupheleni kothumelo.

Nanga amanye amacebiso.

1. Ngeseto zesidlulisi, izibuko ekujoliswe kulo alikhuthazwa ukuba lifane nezibuko lendawo, umzekelo, ungacwangcisa izibuko ekujoliswe kulo 8090.
2. 
3. I-ip yomamkeli kufuneka ifane naleyo ye-transmitter. Umzekelo, ukuba isidluliseli yi-192.168.1.x, umamkeli kufuneka kwakhona abe 192.168.1.x.
4. Izibuko lendawo yomamkeli kufuneka lihambelane nezibuko ekujoliswe kulo lomthumeli, umzekelo, zombini zimiselwe 8090.
5. Umgaqo uyimfuneko ukuba ii-PC ezimbini zinxibelelane ne-UDP yosasazo phantsi kwecandelo le-ip network efanayo, zisete ukuqwalasela icandelo lothungelwano olufanayo lwe-IP, kwaye ke izibuko ekujoliswe kulo lomthumeli kufuneka lihambelane nezibuko lendawo lomamkeli.
6. Eyona nto ibaluleke kakhulu kukuba ikhonkco lendlela enye, kufuneka isebenzise usasazo lwe-UDP/usasazo oluninzi (hayi nakwimfuno), ngoko ke iIP ekujoliswe kuyo yePC kwicala lomthumeli kufuneka imiselwe ukusasaza ip, njenge 192.168.1.255
7. Isibane esiluhlaza kwisiphelo sokwamkela siyadanyaza, ebonisa ukuba ikhonkco elingenazingcingo liqhagamshelwe.
8. Ukuba ubumbeko lulungile, umncedisi womnatha wekhompyuter apho umamkeli akhoyo akabonisi datha efunyenweyo, inokuba yingxaki yefirewall.
9. Kwakhona kunokwenzeka ukuba abancedisi bokulungisa i-network ezininzi bavulwe ngaphambili, Nceda ujonge ikhompyutha ukuqinisekisa ukuba inye kuphela inkqubo yomncedisi wothungelwano esebenzayo.
10. Ukuba i-UDP isasaza ukuhambisa idatha yevidiyo, i-firewall kufuneka ivalwe, kwaye akucaci ukuhambisa idatha encinci ngolo hlobo. Kungcono ukucebisa ukucima i-firewall okanye ukongeza uMncedisi weNethiwekhi kwiinkqubo ezivumelekileyo zomlilo.
11. Kukho imenyu eyehlayo kwikona ephezulu ngasekhohlo, ungakhetha iilwimi-IsiNgesi.
12. Nceda u-ping umthumeli kunye ne-IPs yomamkeli kwiiPC kumacala omabini ukuze uqinisekise ukuba uqhagamshelo lomzimba lwekhadi lothungelwano lulungile.: Qhagamshela iPC ye-transmitter, ping isidluliseli Ip: 192.168.1.30; Qhagamshela iPC yomamkeli, ping umamkeli Ip: 192.168.1.24
13. Qinisekisa ukuba ikhompuyutha yakho efunyenweyo ine-net-assist enye kuphela esebenzayo.
14. Nceda qhawula uqhagamshelwano kwaye emva koko uqhagamshele ukujonga, okanye unganceda ngokukhawuleza emva koko uvulele uvavanyo.

Kule vidiyo, Ndakwazisa indlela yokuqwalasela ngokuchanekileyo umncedisi womnatha kwikhompyuter phambi kokuvavanya imodyuli yothumelo oluselubala lwenethiwekhi..

Isicombululo sovavanyo esingentla sesalo mzekelo ungezantsi.

1. Zonke iisetingi ziqwalaselwe ngokweemfuno zakho, kodwa idatha ayikagqithiselwa, Ndingenza ntoni?

1. Ekuqaleni, nceda ukhuphele kwaye ufake Wireshark kwiipc ezimbini, kwaye uyijonge.
2. 
3. Ipakethe ye-UDP lusasazo oluselubala, ngoko unokubona ipakethe ye-UDP efanayo(umzekelo, umthombo: 192.168.1.40, indawo ekuyiwa kuyo: 192.168.1.255, port: 8090) kumacala omabini pc usebenzisa Wireshark.
4. I-Wireshark kwi-PC yokufumana ifumene ipakethi ye-UDP evela kwi-tx, Ingxaki nje yoncedo lomnatha kwiPC yomamkeli.

2. Kutheni ndibona iifrikhwensi ezimbini ezahlukeneyo kwisixhobo sebhodi yoLungiso lweParameter, xa ndidibanisa le modyuli yendlela enye yenethiwekhi engenazingcingo e transparent transparent?

Le bhodi ineendlela ezimbini zokusetyenziswa. Ukuthunyelwa okumiselweyo kusetyenziswa njenge-relay, ngoko kuya kubakho iiparamitha ze-Tx kunye ne-Rx. Ukuze abathengi bakho bayisebenzise njengendlela enye yenethiwekhi transmitter transparent transmitter, nikela ingqalelo nje kwiparameters kwiphepha le-Tx.

Kucetyiswa ukuba uqale uvavanye ngokwevidiyo engasentla esiyidwelisileyo, kwaye musa ukuguqula iiparamitha.

3. Indlela enye isebenza kakuhle ukudlulisa ividiyo ngedilesi yosasazo njenge 192.168.1.255, Kodwa kufuneka sisebenze kunye nephuli ye-multicast efana ne-239.1.1.1…. Ngoku, I-multicast ayisebenzi, I-tx kunye ne-rx kufuneka idlule i-traffic ye-multicast, Nceda uthumele i-firmware yokuphucula ukusombulula le ngxaki.

Nceda uhlaziye i-firmware engezantsi. (indlela yokuphucula i-firmware?)
