Yuav ua li cas yog lub downhole xyuas system ntawm underwater imaging khoom tsim?

Thawj tiam ntawm kev saib xyuas hauv av suav nrog cov tshuaj analogcctv dej lub koob yees duabkev saib xyuas uas tso siab rau cov cuab yeej tshwj xeeb xws li lub koob yees duab cable video recorder saib.

Cov txheej txheem scalability txwv tsis pub muaj feem ntau txwv los ntawm cov tswv yim muaj peev xwm ntawm video splitters, matrices, thiab switchers. Lub koob yees duab outputs video signals los ntawm ib tug tshwj xeeb coaxial cable. Cables txuas nrog rau cov khoom siv yees duab tshwj xeeb rau kev saib xyuas analog yog txwv los ntawm analog video cable kis tau tus mob ntev thiab cable amplifier txwv los txhawb kev saib xyuas hauv zos nkaus xwb. Cov yeeb yaj kiab tsis zoo yog thawj qhov txwv. Cov yeeb yaj kiab zoo txo ​​qis thaum cov ntawv luam nce ntxiv.

Cov neeg siv uas hnyav video load yuav tsum tshem tawm los yog hloov daim videotape los ntawm VCR rau cia, thiab cov videotape yog ib qho yooj yim mus nyiag los yog inadvertently erased los yog ploj.

Qhov thib ob-tiam underground saib xyuas analog-digital soj ntsuam system tseem siv coaxial cable los tso tawm video signals los ntawm lub koob yees duab mus rau DVR. Lub hard disk video recorder DVR yog qhov nruab nrab ib nrab-analog-semi-digital tswvyim, uas tuaj yeem txhawb nqa IP network tsis pub nkag los ntawm DVR thiab tseem txhawb nqa video thiab playback. DVR cov khoom lag luam tsis muaj ntau yam qauv, yog li lub cim ntawm cov tshuab no yog kaw kaw, thiab tseem muaj ntau qhov kev txwv hauv DVR system. Limited Scalability Qhov kev txwv ntawm DVRs yog tias lawv tsuas tuaj yeem nthuav mus txog 16 lub koob yees duab ib zaug. Cov txheej txheem cabling complex analog-rau-digital tseem xav tau kev teeb tsa ntawm cov kab hluav taws xob sib cais ntawm txhua lub koob yees duab, uas ua rau muaj kev sib tw cabling.

Kev tswj tsis tau txwv Koj xav tau cov servers sab nraud thiab kev tswj hwm software los tswj ntau DVRs lossis saib xyuas cov ntsiab lus. Txwv tej thaj chaw deb saib xyuas/tswj muaj peev xwm Koj nkag tsis tau tej lub koob yees duab los ntawm ib tug neeg. Analog-digital video recordings yog qhov ua rau poob yam tsis muaj kev saib xyuas.

Qhov thib peb tiam ntawm kev soj ntsuam video yog yuav ua kom tiav IP video soj ntsuam system. IPVS yog tag nrho-IP video soj ntsuam qhov system uas txawv ntawm ob txoj kev npaj dhau los.

Qhov kom zoo dua ntawm cov kab ke no yog tias lub koob yees duab muaj lub web server tsim thiab xa ncaj qha mus rau Ethernet chaw nres nkoj. Cov koob yees duab no tsim JPEG lossis MPEG4 cov ntaub ntawv cov ntaub ntawv uas tuaj yeem nkag mus tau, saib xyuas, kaw, thiab luam tawm los ntawm txhua tus neeg siv tau tso cai los ntawm ib qho chaw hauv lub network es tsis txhob tsim cov teeb liab analog video txuas ntxiv los kos tag nrho IP video soj ntsuam. Nws cov txiaj ntsig zoo yog nyob rau hauv kev yooj yim, sib sau ua ke ntawm kev rov ua dua Spare nco, muaj zog hauv nruab nrab kev tswj hwm, kev saib xyuas cov chaw taws teeb tshwj xeeb, thiab daim kab xev thaub qab khaws cia thev naus laus zis ruaj khov tiv thaiv daim duab saib xyuas los ntawm kev ua haujlwm nyuaj.
