Bukatun aiki

Samfurin lantarki na R&D yana aiwatar da sauraron murya
Lokacin zayyana tsarin hardware, maki da yawa yakamata su bayyana a sarari:
1. Bukatun aiki:
1.1 yanayin samar da wutar lantarki da kariya
Akwai hanyoyi guda biyu: na'urar samar da wutar lantarki da aka gina a kai tsaye ana ba da ita ta hanyar samar da wutar lantarki ta hanyar wutar lantarki ko na waje da aka tsara wutar lantarki ta DC), ana ɗaukar ginin da aka gina a cikin wutar lantarki, kuma ana buƙatar ƙirar wutar lantarki gabaɗaya. daban.Dangane da ƙayyadaddun ƙira daban-daban na sauya wutar lantarki a cikin masana'antu daban-daban, yana buƙatar tsara shi bisa ga ka'idodin masana'antu daban-daban.Wutar wutar lantarki da aka tsara ta DC na waje na iya sauƙaƙa sashin samar da wutar lantarki na tsarin hardware, Amma kuna buƙatar wutar lantarki ta waje.
Ana buƙatar kayan sarrafa masana'antu ko kayan aikin likita ta POE (ikon kan Ethernet).POE: fasahar cat Ethernet 5 data kasance wacce zata iya samar da wutar lantarki ta DC don wasu tashoshi na tushen IP (wayar IP, WLAN access point AP, kyamarar cibiyar sadarwa, da sauransu) yayin watsa sigina ba tare da wani canji ga abubuwan more rayuwa ba.IEEE 802.3af (fitarwa ƙarfin lantarki 44-57v da ƙarfin fitarwa 15.7w) shine ma'auni na farko da ƙa'idodin aiwatarwa na yau da kullun.IEEE 802.3at (fitarwa ƙarfin lantarki 50-57v da ƙarfin fitarwa 25.5w) ana samar da ta tasha mai ƙarfi.
1.2 shigarwa da siginar fitarwa;
1.3 aikin sadarwa mara waya
Ana iya amfani da Gprs-23bps azaman tashar tashar jiragen ruwa a cikin tsarin GPRS da aka haɓaka, kuma ana iya amfani da ɗaya a cikin tsarin sadarwa na gprs-23bps, WiFi (ieee802.11x) shine babban ma'aunin fasaha na WLAN a halin yanzu.Iyawar WLAN tana warware bukatun sadarwar masu amfani a cikin 100m na ​​ƙarshe.WiFi yana tsara Layer na zahiri (PHY) da Layer ikon samun damar watsa labarai (MAC) na yarjejeniya, kuma yana ɗaukar TCP / IP azaman Layer na cibiyar sadarwa.
1.4 bluetooth (cikakken watsa duplex) fasaha ce ta rediyo da ke tallafawa sadarwa ta gajeriyar hanya (<10m);

1.5 IrDA (gajeren ƙungiyar bayanan infrared, daidaitaccen IrDA1.0 yana tsara tsarin daidaitawa na serial da rabi na duplex. Ka'idojin bayanan sa sun ƙunshi ka'idoji guda uku: Layer na zahiri, Layer access Layer da Layer management Layer. IrDA Codec IC da transceiver masu kaya galibi sun haɗa da Ti, ATMEL, NXP, Vishay, kaifi microelectronics, Everlight lantarki, Taiwan HL, Holtek semiconductor);
1,6 NFC (fasahar sadarwa mara igiyar gajeriyar zango), ganowa mara lamba da fasahar haɗin kai, haɗe tare da mai karanta katin inductive, kati inductive da aikin batu-zuwa a guntu ɗaya, na iya ganowa da musayar bayanai tare da na'urori masu jituwa a ciki. nesa kadan.Nisa na NFC shine kusan 10cm,

1.7 Fasahar sadarwa mai ɗaukar kaya mara waya ta UWB
1.8 mitar mitar mitar layi mai saurin yada fasahar bakan
1.9 Fasahar tantance mitar rediyo na RFID, wacce kuma aka sani da fasahar tantancewa mara waya, ta kasu kashi-kashi mai aiki (bayanin gajeren zango, katin ID na ƙarni na biyu, katin bas, katin cin abinci da katin banki), m (shiri mai hankali, filin ajiye motoci na hankali) da samfuran rabin aiki (haɗa fa'idodin aiki da m, ƙaramar faɗakarwa don daidaitaccen matsayi, gano nesa mai nisa da loda bayanai)

2. Gabaɗaya bukatun aiki
Abubuwan da ake buƙata na aikin gabaɗaya sun haɗa da: ikon sarrafa bayanan shigar da bayanai, buƙatun tsarin aiki akan yanayin zafi da zafi, buƙatun mara lahani da kwanciyar hankali na tsarin, ƙimar ingancin kuzarin tsarin da kariyar kai. bukatun tsarin
2.1 buƙatun aikin don bayanai sun haɗa da matsakaicin iyakar bandwidth wanda zai iya aiwatar da bayanai, aikin ainihin lokacin sarrafa bayanan da daidaiton tattara bayanai,
2.2 don daidaita tsarin zuwa yanayin, za a ƙayyade zafin jiki da yanayin muhalli na samfurin a cikin matakin buƙata.Yanayin zafin jiki da yanayin muhalli na samfurin sune 0-70 ° C, masana'antu sa - 40-85 da digiri na soja - 55-150 鈩�,
