Nā koi hana

Ke kaʻina R&D huahana uila e hoʻolohe ana i ka leo
I ka hoʻolālā ʻana i kahi ʻōnaehana hāmeʻa, pono e akaka kekahi mau kikoʻī:
1. Pono pono:
1.1 mana lako hana a me ka pale
ʻElua mau ala: hoʻolako pololei ʻia ka papa lako mana i kūkulu ʻia mai ka mana nui a i ʻole ka mana o waho DC regulated power supply), ua apono ʻia ka papa lako mana i kūkulu ʻia, a pono e hoʻolālā ʻia ka papa lako mana hoʻololi. kaawale.E like me nā kikoʻī hoʻolālā like ʻole o ka hoʻololi ʻana i ka mana i nā ʻoihana like ʻole, pono e hoʻolālā ʻia e like me nā kūlana ʻoihana like ʻole.Hiki ke hoʻomaʻamaʻa ka mana o waho DC i ka mana lako o ka ʻōnaehana lako, akā pono ʻoe i kahi lako mana waho.
Pono e hoʻohana ʻia nā lako mana ʻoihana a i ʻole nā ​​​​mea lapaʻau e POE (ka mana ma luna o Ethernet).POE: ʻenehana cat Ethernet 5 i loaʻa i hiki ke hāʻawi i ka mana DC no kekahi mau kikowaena IP (kelepona IP, WLAN access point AP, pahupaʻikiʻi pūnaewele, a me nā mea ʻē aʻe) ʻoiai e hoʻouna ana i nā hōʻailona me ka ʻole o ka hoʻololi ʻana i ka ʻōnaehana.ʻO IEEE 802.3af (ka uila puka 44-57v a me ka mana puka 15.7w) ʻo ia ka maʻamau mua a me ka maʻamau hoʻokō mainstream.Hoʻokumu ʻia ka IEEE 802.3at (ka uila puka 50-57v a me ka mana hoʻopuka 25.5w) e ka pahu mana kiʻekiʻe.
1.2 hōʻailona hoʻokomo a hoʻopuka;
1.3 hana kamaʻilio uila
Hiki ke hoʻohana ʻia ʻo Gprs-23bps ma ke ʻano he port serial i ka module GPRS i hoʻomohala ʻia, a hiki ke hoʻohana ʻia kekahi i ka module communication gprs-23bps i kūkulu ʻia, ʻo WiFi (ieee802.11x) ka maʻamau ʻenehana nui o WLAN i kēia manawa.Hoʻoponopono ka portability o WLAN i nā pono kamaʻilio o nā mea hoʻohana i ka 100m hope loa.Hoʻokumu ʻo WiFi i ka papa kino (PHY) a me ka papa hoʻokele media access control (MAC) o ka protocol, a lawe iā TCP / IP ma ke ʻano he papa pūnaewele.
1.4bluetooth (full duplex transmission) he ʻenehana lekiō e kākoʻo ana i nā lako kamaʻilio pōkole (<10m);

1.5 IrDA (pōkole no ka hui ʻikepili infrared, IrDA1.0 maʻamau e hoʻokumu i kahi ʻōnaehana hoʻonohonoho serial a me ka hapalua duplex. Aia kona protocol data i ʻekolu mau kuʻuna kumu: ka papa kino, ka papa kuhikuhi loulou a me ka papa hoʻokele loulou. ʻO IrDA codec IC a me nā mea hoʻolako transceiver ka nui Ti, ATMEL, NXP, Vishay, microelectronics koi, uila uila Everlight, Taiwan HL, Holtek semiconductor);
ʻO 1,6 NFC (ʻenehana kelepona ʻole pōkole), ʻike ʻike ʻole a me ka ʻenehana interconnection, i hui pū ʻia me ka heluhelu kāleka inductive, kāleka inductive a me ka hana point-to-point ma kahi pahu hoʻokahi, hiki ke hoʻomaopopo a hoʻololi i ka ʻikepili me nā mea kūpono i loko. kahi mamao iki.ʻO ka mamao o NFC ma kahi o 10cm,

1.7 UWB ʻenehana kamaʻilio kelepona
1.8 laina laina alapine modulation hohola spectrum enehana
1.9 RFID radio frequency identification technology, also known as wireless identification technology, is shared into active (pōkole-manawa identification, second-generation ID card, bus card, meal card and bank card), passive (intelligent transport, intelligent parking lot) a nā huahana semi-active (ka hui pū ʻana i nā pono o ka ikaika a me ka passive, haʻahaʻa-frequency trigger no ka hoʻonohonoho pololei ʻana, ʻike lōʻihi a me ka hoʻouka ʻana i ka ʻikepili)

2. Nā koi hana holoʻokoʻa
ʻO nā koi hana holoʻokoʻa e pili ana: ka hiki ke hoʻololi i ka ʻikepili hoʻokomo, nā koi o ka hana ʻana o ka ʻōnaehana ma ke ʻano wela a me ka haʻahaʻa, nā koi o ka manawa hana hewa ʻole a paʻa o ka ʻōnaehana, ka pae ikehu o ka ʻōnaehana a me ka pale ponoʻī. nā koi o ka ʻōnaehana
ʻO 2.1 nā koi o ka hana no ka ʻikepili e pili ana i ka bandwidth kiʻekiʻe e hiki ke hana i ka ʻikepili, ka hana manawa maoli o ka hoʻoili ʻana i ka ʻikepili a me ka pololei o ka hōʻiliʻili ʻana i ka ʻikepili,
2.2 no ka hoʻololi ʻana o ka ʻōnaehana i ke kaiapuni, e hoʻoholo ʻia ka mahana a me ka pae kaiapuni o ka huahana i ka pae koi.ʻO ka mahana a me ka pae kaiapuni o ka huahana he 0-70 鈩�, ʻoihana ʻenehana - 40-85 鈩� a me ka pūʻali koa - 55-150 鈩�,
