Keeb kwm
Txhawm rau daws qhov teeb meem kev sib txuas lus lav qhov teeb meem hauv kev tsim kho theem ntawm lub subway qhov.Yog tias koj siv cov xaim hluav taws xob, nws tsis yog tsuas yog yooj yim los rhuav tshem thiab nyuaj rau nteg, tab sis kuj cov kev xav tau ntawm kev sib txuas lus thiab ib puag ncig hloov pauv sai thiab tsis tuaj yeem ua tiav.Hauv qhov no, kev sib txuas lus wireless yog txoj hauv kev zoo tshaj plaws.
Txawm li cas los xij, lub subway tunnel yog nqaim thiab nkhaus, nws yog qhov nyuaj rau cov tsoos wireless xov tooj cua kev sib txuas lus txhais tau tias yuav daws tau qhov kev sib txuas lus tiag tiag.Yog li ntawd, IWAVE tau tsim ib qho kev sib koom ua ke ntse network daws teeb meem rau4G Private Network + MESH ad hoc networkkev koom tes kev pab them nqi thiab ua tiav qhov kev sim cov nyhuv.
Hauv qhov kev sim no, ntu ntawm Chaw Nres Nkoj A mus rau Chaw Nres Nkoj B hauv qhov av ntawm Tianjin Metro Kab 4 raug xaiv.

Kev xa tawm ib ntus ntawm Command Dispatcher
Lub IWAVE 4G portable system muaj wired thiab wireless access functions.Yog li ntawd, raws li ib tug mobile hais kom ua dispatching chaw nres tsheb (notebook los yog industrial-qib ntsiav tshuaj) ntawm ib ntus hais kom ua chaw, nws yuav tsum deployed nyob rau hauv ib tug muaj kev ruaj ntseg cheeb tsam mus nqa tawm mobile command dispatch thiab saib video rov qab.
Kev xeem
Solution 1: 4G Private Network kev pab cuam kuaj
Thaum pib ntawm qhov kev xeem, cov neeg sim tau nqa 4G tus tub rog tub rog lub davhlau ya nyob twg (nrog lub xub pwg nyom lub koob yees duab) thiab lub tes tsho 4G ntiag tug network davhlau ya nyob twg nkag mus thiab txav mus tom ntej ntawm qhov nkag.Lub suab intercom thiab video rov qab tau zoo nyob rau hauv seem ntsuab ntawm daim duab hauv qab no, daig hauv txoj haujlwm daj, thiab offline thaum nws nyob hauv txoj haujlwm liab.
Qhov chaw pib ntawm qhov daj yog nyob ntawm 724-ntiv nplhaib (los ntawm qhov chaw nres tsheb hauv paus, 366meters ua ntej tig, 695 meters tom qab tig, tag nrho ntawm 1.06km);qhov poob kev twb kev txuas txoj hauj lwm yog nyob rau ntawm 800-ntiv taw tes (los ntawm lub hauv paus chaw nres tsheb txoj hauj lwm, 366 meters ua ntej tig, 820 meters tom qab tig, tag nrho ntawm 1.18km).Thaum lub sij hawm xeem, tus yees duab tau du, thiab lub suab yog meej.

Kev daws 2: 4G Private Network + MESH ad hoc network kev koom tes nrog kev xeem.
Peb thim rov qab mus rau qhov chaw nyob deb ntawm thaj tsam ntawm ntug kev daws teeb meem 1, nrhiav qhov chaw tso chaw tsim nyog, thiab xaiv 625-ntiv nplhaib txoj hauj lwm (me ntsis ua ntej 724-ntiv nplhaib txoj hauj lwm) los tso lub No. 1 MESH Relay ntaus ntawv.Saib daim duab sab xis:
Tom qab ntawd tus tester nqa lub No. 2 MESH (nrog lub xub pwg clip lub koob yees duab) thiab ib tug handheld 4G private network handheld (txuas mus rau MESH relay los ntawm Wi-Fi) mus txuas ntxiv mus sim, thiab lub suab hais lus rov qab thiab cov video rov qab yog khaws cia du tag nrho. lub sijhawm.

Kev sib txuas lus tau raug txiav tawm ntawm txoj haujlwm 850-ntiv nplhaib thiab qhov kev pab cuam ntawm ib theem MESH yog 338meters.
Thaum kawg, peb xaiv ntxiv No.3 MESH ntaus ntawv ntawm txoj hauj lwm ntawm 780-nplhaib los sim cov nyhuv MESH cascading.
Tus tester nqa lub No. 3 MESH thiab lub koob yees duab mus rau qhov kev xeem, taug kev mus rau qhov chaw tsim kho ntawm qhov kawg ntawm lub qhov (kwv yees li 60 meters tom qab 855-ntiv nplhaib), thiab cov yeeb yaj kiab tau du tag nrho.
Vim kev tsim kho ua ntej, qhov kev xeem dhau lawm.Thoob plaws hauv txoj kev sim, cov yeeb yaj kiab yog du, thiab lub suab thiab cov yeeb yaj kiab yog qhov tseeb.

Cov ntsiab lus xeem
Los ntawm kev sib txuas lus kev ntsuam xyuas ntawm tus kheej network nyob rau hauv lub subway qhov, cov nram qab no zoo yog embodied nyob rau hauv lub subway tunnel engineering daim ntawv thov raws li lub tswv yim ntawm 4G Private Network + MESH ad hoc network koom tes kev pab them nqi.
- Qhov system muaj kev sib koom ua ke sai heev
Cov kab ke no yog kev sib koom ua ke (built-in integrated power supply, core network, base station, dispatching server, and other equipment).Lub thawv txais kev tsim qauv peb-pov thawj.Tsis tas yuav qhib lub thawv, Ib-nias khau raj, tsis tas yuav teeb tsa thiab hloov pauv tsis sib xws thaum siv nws, kom nws tuaj yeem xa mus sai sai hauv 10 feeb thaum muaj xwm txheej ceev.
- Kev sib txuas lus ruaj khov muaj peev xwm nyob rau hauv ib puag ncig hnyav
4G Cov txheej txheem kev sib txuas lus ntiag tug muaj qhov zoo ntawm qhov kev pab cuam nyob deb, hloov pauv hloov pauv ntawm MESH, kev sib txuas ceev ceev ntawm qhov nruab nrab ad hoc network, ntau theem kev sib txuas sib txuas, thiab kev sib txuas tshwj xeeb tsim kom muaj peev xwm sib txuas lus hauv ib puag ncig nyuaj.Hauv hom no, kev sib txuas lus sib txuas tuaj yeem txav tau sai txhua lub sijhawm, yog tias tsim nyog, kev pab them nqi tuaj yeem nce ntxiv txhua lub sijhawm.
- Muaj zog siv tau ntawm kev lag luam kev lag luam
Tom qab kev xa tawm ntawm lub kaw lus, lub network nkag tau muab, lub interface qhib, thiab tus qauv WIFI thiab cov chaw nres nkoj network tau muab.Nws tuaj yeem muab kev sib txuas lus wireless rau ntau yam kev pabcuam ntawm kev tsim kho subway.Kev ua haujlwm ntawm cov neeg ua haujlwm, kuaj xyuas kev tuaj koom, chaw ua haujlwm txawb thiab lwm yam kev lag luam kuj tuaj yeem siv lub network no los ua haujlwm.
Xaus
Hauv cov ntsiab lus, qhov kev ntsuam xyuas no ua pov thawj tag nrho tias kev sib txuas ua ke ntawm 4G ntiag tug network thiab MESH ad hoc network yog ib qho kev daws teeb meem zoo heev, uas tuaj yeem daws cov teeb meem ntawm kev sib txuas lus hauv kev sib txuas hauv subway tunnels thiab ib puag ncig hnyav.
