Smart Audio Networks mu Public Transportation: Kumanga Njira Zoyankhulirana Zomveka komanso Zodalirika
Malo amakono a zoyendera za anthu afika povuta kwambiri. Mabwalo a ndege, masiteshoni a metro, malo okwerera mabasi, ndi malo okwerera masitima apamtunda tsopano amanyamula anthu ambiri tsiku lililonse, zomwe zimapangitsa kulankhulana momveka bwino komanso kwanthawi yake kukhala gawo lofunika kwambiri pazochitika zatsiku ndi tsiku. Makina omvera salinso ongolengeza, tsopano ndi gawo la njira zolumikizirana zolumikizirana zomwe zimathandizira chitetezo, kulumikizana, komanso zochitika zonyamula anthu.
Pakatikati pa kusinthaku ndikusintha kuchokera kumayendedwe apawailesi yakanema kupita kumayendedwe olumikizirana pamaneti omangidwa paukadaulo wa IP.
Kuchokera pa Kuwulutsa Kwachikale kupita ku Networked Audio
Kuyika maadiresi wamba kumadalira kwambiri mawaya a analogi ndi amplifiers apakati. Ngakhale kuti zimagwira ntchito, machitidwewa nthawi zambiri amavutika ndi scalability ndi kukonza, makamaka m'malo akuluakulu amayendedwe komwe kukulitsa ndi kusinthasintha kwa magawo ndikofunikira.
Masiku ano, oyendetsa mayendedwe akusunthira kwambiri kumayendedwe olumikizirana a IP. Makinawa amafalitsa ma audio ngati ma digito pamanetiweki wamba, kulola kuwongolera kwapakati ndikugawidwa kumadera ndi nyumba zingapo. Izi zimawapangitsa kukhala osinthika kwambiri pazofuna zamakono zamakono.
VNETPA yakhala ikupanga mayankho omwe amathandizira kusinthaku, kuyang'ana kwambiri zosinthika, zowopsa, komanso zoyankhulirana zapamwamba zopangidwira mayendedwe enieni apadziko lonse lapansi.
Udindo wa IP Speaker Technology mu Transportation
Chimodzi mwazinthu zofunikira pakutumizidwa kwamakono ndiIP speaker. Mosiyana ndi olankhula achikhalidwe, olankhula a IP amalumikizana mwachindunji ndi netiweki, kupangitsa kuti pakhale ntchito yodziyimira pawokha, kuwongolera madera, komanso kuyang'anira kutali.
M'malo oyendera, izi zikutanthauza:
● Zilengezo za nthawi yeniyeni m'mapulatifomu angapo
● Zidziwitso zadzidzidzi ndikutsegula pompopompo
● Kutumiza mauthenga kwa materminal kapena madera osiyanasiyana
● Kuchepetsa kudalira hardware yapakati
Zomangamanga zogawidwazi zimathandizira kudalirika ndikuonetsetsa kuti ngakhale node imodzi ikulephera, dongosolo lonselo likupitiriza kugwira ntchito popanda kusokoneza.
Chifukwa Chake Kulumikizana kwa SIP Ndikofunikira
Wosanjikiza wina wofunikira m'machitidwe amakono ndikugwiritsa ntchitoSIP (Session Initiation Protocol). SIP imathandizira zida zomvera ndi njira zoyankhulirana kuti zilumikizane mosasunthika pamanetiweki a IP, zomwe zimapangitsa kuti zitheke kuphatikizira ma adilesi a anthu ndi machitidwe a VoIP, ma intercom, ndi nsanja zowongolera.
Pakugwiritsa ntchito, SIP imalola oyendetsa mayendedwe kuti:
● Yambitsani zilengezo kuchokera kumalo otumizira mauthenga
● Gwirizanitsani mapeji ndi machitidwe omwe alipo kale
● Yambitsani kulankhulana m’njira ziwiri m’madera ovuta
● Kuchepetsa kasamalidwe ka makina pogwiritsa ntchito ndondomeko zokhazikika
Potengera SIP, malo opangira mayendedwe amapeza njira yolumikizirana yolumikizana yomwe imachepetsa zovuta zamadongosolo ndikuwongolera magwiridwe antchito.
Kumanga Njira Yogwirizana ya PA ya Zomangamanga Zamakono
A zamakonoPA Systemm'mayendedwe salinso njira yomvera yokhayokha. Ndi gawo la chilengedwe chokulirapo chomwe chimalumikiza okamba, mapulatifomu owongolera, machitidwe azadzidzidzi, ndi ma network.
Njira ya VNETPA imayang'ana kwambiri pamakina omanga omwe ndi:
● Zokwera pamasiteshoni ang'onoang'ono kapena ma eyapoti akuluakulu apadziko lonse lapansi
● Yogwirizana ndi IP yochokera
● Zosavuta kuphatikiza ndi nsanja zachitatu
● Zapangidwira kuti zizigwira ntchito mosalekeza pansi pazovuta kwambiri
Njira yoyamba yophatikizirayi imatsimikizira kuti kuyankhulana kumakhalabe kokhazikika, komveka bwino, komanso koyankhira pazochitika zonse zogwirira ntchito.
Kupititsa patsogolo luso laokwera komanso chitetezo chogwira ntchito
Kulankhulana momveka bwino kumakhudza mwachindunji chitetezo komanso kuchita bwino. Muzochitika zadzidzidzi, masekondi ndi ofunika. M'ntchito za tsiku ndi tsiku, kumveka bwino kumachepetsa chisokonezo ndikuwongolera kuyenda kwa okwera.
Mwa kuphatikiza ukadaulo wa IP speaker, kulumikizana kwa SIP, ndi kapangidwe kanzeru ka PA System, oyendetsa mayendedwe amatha kukwaniritsa:
● Nthawi yoyankha mwachangu
● Kuwongolera bwino kwa okwera
● Kuwongolera pakati pamasamba angapo
● Kuchepetsa zovuta kukonza
Ubwinowu umathandizira kuti ntchito ziziyenda bwino komanso kuti anthu azikhala odalirika.
Malangizo a VNETPA mu Smart Audio Communication
Pamene machitidwe amayendedwe akupitilirabe kusinthika, kufunikira kwa mayankho anzeru komanso ochezera pa intaneti kudzangowonjezereka. VNETPA ikupitiriza kuyang'ana kwambiri pakupanga njira zamakono zoyankhulirana zomwe zimagwirizana ndi izi, kupereka mayankho omwe ali othandiza, owopsa, komanso okonzeka mtsogolo.
Cholinga chake ndi chosavuta: kupangitsa kuti kulumikizana kumveke bwino, mwachangu, komanso kudalilika kudzera pazida zapamwamba zomvera za IP.
