Background
Kugadzirisa dambudziko revimbiso yekutaurirana munhanho yekuvaka ye subway tunnel.Kana ukashandisa waya network, hazvisi nyore kuparadza uye zvakaoma kuisa, asiwo kutaurirana zvinodiwa uye zvakatipoteredza zviri kuchinja nokukurumidza uye hazvigone kuwanikwa.Muchiitiko ichi, kutaurirana kusina wireless ndiyo nzira inonyanya kushanda.
Nekudaro, nzira yepasi pevhu yakamanikana uye yakakombama, zvakaoma kune yechinyakare isina waya Radio Communication System zvinoreva kugadzirisa zvechokwadi kuvharika kwekutaurirana.Naizvozvo, IWAVE yakagadzira yakasanganiswa yakangwara network mhinduro ye4G Yakavanzika Network + MESH ad hoc networkkubatana kufukidza uye kuita bvunzo yemhedzisiro.
Muyedzo iyi, chikamu kubva paChiteshi A kuenda kuChiteshi B mumugero weTianjin Metro Line 4 chakasarudzwa.

a) Kuona kukurumidza kuendesa kugona kweLTE Yakavanzika Network.
b) Kuonesa kugona kwekuvhara kweiyo yega Backpack musoja tunnel chiitiko.
c) Kuonesa kushanda kwe "4G LTE Yakavanzika Network + MESH Ad hoc Network yekudyidzana yekuvhara" kuti uwane kufukidzwa kuzere.
d) Kuona kutakura kwekuongorora

Kuiswa kwenguva pfupi kweCommand Dispatcher
Iyo IWAVE 4G inotakurika sisitimu ine waya uye isina waya yekuwana mabasa.Naizvozvo, senharembozha yekutumira chiteshi (notibhuku kana indasitiri-giredhi piritsi) yenzvimbo yenguva yekuraira, inogona kuiswa munzvimbo yakachengeteka kuita nhare yekuraira kutumira uye kuona vhidhiyo kudzoka.
Testing Process
Solution1: 4G Yakavanzika Network yekuvhara Kuedzwa
Pakutanga kwekuyedzwa, vaedzi vakatakura 4G yega musoja handset terminal (yakashongedzerwa nepfudzi clip kamera) uye yakabata ruoko 4G yakavanzika network terminal kuti vapinde uye vafambire mberi kubva pamusuwo wenzira.Voice intercom uye vhidhiyo kudzoka yanga yakatsetseka muchikamu chegirinhi chemufananidzo pazasi, yakanamira munzvimbo yero, uye isina mhepo kana iri munzvimbo dzvuku.
Nzvimbo yekutanga yechikamu cheyero iri pa724-ring point (kubva pa base station station, 366metres isati yatendeuka, 695 metres mushure mekutendeuka, yakazara 1.06km);nzvimbo yakarasika yekubatanidza iri pa800-ring point (kubva pa base station station, 366 metres isati yatendeuka, 820 metres mushure mekutendeuka, yakazara 1.18km).Panguva yokuedzwa, vhidhiyo yacho yakanga yakatsetseka, uye inzwi rakanga rakajeka.

Mhinduro 2: 4G Yakavanzika Network + MESH ad hoc network yekudyidzana yekuvhara Kuedzwa.
Takadzokera kure kure nenzvimbo yakafukidzwa nemucheto weSolution 1, tsvaga nzvimbo yakakodzera yekuisa, uye takasarudza nzvimbo ye-625-ring (zvishoma pamberi pe724-ring position) kuti tiise No. 1 MESH Relay device.Ona mufananidzo kurudyi:
Ipapo muedzi akatakura No. 2 MESH (yakashongedzerwa nekamera yepafudzi) uye yakabata ruoko 4G yakavanzika network handheld (yakabatana neMESH relay kuburikidza neWi-Fi) kuti ienderere mberi nekuyedza, uye kutaura kwezwi nekudzoka kwevhidhiyo zvinochengetwa zvakanaka zvese. nguva.

Kukurukurirana kwakabviswa panzvimbo ye850-ring uye nzvimbo yekuvhara yechikamu chimwe chete MESH i338meters.
Pakupedzisira, takasarudza kuwedzera No.3 MESH mudziyo panzvimbo ye780-ring kuti uedze MESH cascading effect.
Muedzi akatakura No. 3 MESH uye kamera kuti ienderere mberi nemuedzo, yakafamba ichienda kunzvimbo yekuvaka pamagumo emugero (anenge mamita makumi matanhatu mushure me855-ring), uye vhidhiyo yakanga yakanyatsonaka nzira yose.
Nekuda kwekuvakwa kuri mberi, bvunzo yapera.Munguva yese yekuyedza, vhidhiyo yacho yakatsetseka, uye izwi nevhidhiyo zvakajeka.

Testing Summary
Kuburikidza neyedzo yekuvhara yekutaurirana yeyakavanzika network mumugero wepasi pevhu, zvinotevera zvakanakira zvinoiswa mukati me subway tunnel engineering application zvichienderana nechirongwa che4G Private Network + MESH ad hoc network cooperative coverage.
- Sisitimu yakanyatsobatanidzwa nekukurumidza kutumira
Iyi sisitimu yakanyatsobatanidzwa (yakavakirwa-mukati yakabatanidzwa magetsi ekupa, musimboti network, base station, kutumira server, uye zvimwe zvishandiso).Bhokisi racho rinotora matatu-uchapupu chimiro dhizaini.Hapana chikonzero chekuvhura bhokisi, One-tinya bhutsu, hapana chikonzero chekugadzirisa uye kushandura parameter disassemble paunenge uchiishandisa, kuitira kuti inogona kukurumidza kutumirwa mu10 maminetsi munyaya yekununurwa kwekukurumidzira.
- Yakasimba vimbiso yekugona kutaurirana munzvimbo dzakaoma
4G Iyo yakavanzika network yekutaurirana system ine zvakanakira kuvharira kure, kuchinjika kufananidzwa kweMESH, kukurumidza kubatana kwecenterless ad hoc network, multi-stage yekubatanidza network, uye yakasarudzika network dhizaini inovimbisa kugona kwekutaurirana munzvimbo yakaoma.Mune iyi modhi, network yekukurukurirana inogona kukurumidza kufamba chero nguva, kana zvichidikanwa, kuvharika kunogona kuwedzerwa chero nguva.
- Kushanda kwakasimba kwezvikumbiro zvebhizinesi
Mushure mekutumirwa kwehurongwa, iyo network yekuwana inopiwa, iyo interface yakavhurika, uye yakajairwa WIFI uye network ports inopihwa.Iyo inogona kupa isina waya yekutapurirana chiteshi kune akasiyana masevhisi ekuvaka metro.Kumisikidzwa kwevashandi, kutarisa kwekuuya, nharembozha uye mamwe masisitimu ebhizinesi anogona zvakare kushandisa iyi network kushanda.
Mhedziso
Muchidimbu, kuedzwa uku kunosimbisa zvizere kuti musanganiswa we networking mode ye4G yakavanzika network uye MESH ad hoc network imhinduro yakanaka kwazvo, inogona kugadzirisa dambudziko rematanho ekutaurirana mumatanho akaomarara epasi uye nharaunda dzakakomba.
