Umkhiqizo we-elekthronikhi R & D inqubo yokulalela izwi
Lapho uklama isistimu yehadiwe, amaphuzu amaningana kufanele acace:
1. Izidingo zokusebenza:
1.1 Imodi yokunikezwa kwamandla kanye nokuvikela
Kunezindlela ezimbili: ibhodi elakhelwe ngaphakathi lokuphakela amandla linikezwa ngokuqondile kusuka kugesi ohamba phambili noma ugesi wangaphandle olawulwa yi-DC), ibhodi elakhelwe ngaphakathi elinikezela ngogesi liyamukelwa, futhi ibhodi lokuphakela amandla elishintshayo ngokuvamile lidinga ukuklanywa. ngokwehlukana.Ngokuya ngemiklamo ehlukene yokucaciswa kokushintshwa kwamandla kagesi ezimbonini ezahlukene, idinga ukuklanywa ngokuya ngamazinga emboni ahlukene.I-DC yangaphandle elawulwayo kagesi ingenza lula ingxenye yokuphakelwa kwamandla yohlelo lwehadiwe, Kodwa udinga ukunikezwa kwamandla kwangaphandle.
Imishini yokulawula izimboni noma okokwelashwa kumele kunikwe amandla yi-POE (amandla phezu kwe-Ethernet).I-POE: ubuchwepheshe obukhona bekati be-Ethernet 5 obungahlinzeka ngogesi we-DC kwamanye amatheminali asekelwe ku-IP (ifoni ye-IP, iphoyinti lokufinyelela le-WLAN AP, ikhamera yenethiwekhi, njll.) ngenkathi idlulisela amasignali ngaphandle kwanoma yiluphi ushintsho kwingqalasizinda.I-IEEE 802.3af (i-voltage ephumayo engu-44-57v namandla okukhiphayo angu-15.7w) iyindinganiso yokuqala kanye nezinga elijwayelekile lokuqalisa.I-IEEE 802.3at (i-voltage ephumayo engu-50-57v namandla okukhiphayo angu-25.5w) ikhiqizwa ukuphela kwamandla aphezulu.
1.2 amasignali okokufaka nokuphumayo;
1.3 Umsebenzi wokuxhumana okungenantambo
I-Gprs-23bps ingasetshenziswa njengembobo ye-serial kumojula ye-GPRS ethuthukisiwe, futhi eyodwa ingasetshenziswa kumojula yokuxhumana ye-gprs-23bps ethuthukisiwe, i-WiFi (ieee802.11x) iyindinganiso yobuchwepheshe eyinhloko ye-WLAN okwamanje.Ukuphatheka kwe-WLAN kuxazulula izidingo zokuxhumana zabasebenzisi ku-100m wokugcina.I-WiFi yakha isendlalelo esibonakalayo (PHY) kanye nosendlalelo sokulawula ukufinyelela kwemidiya (MAC) sephrothokholi, futhi ithatha i-TCP/IP njengesendlalelo senethiwekhi.
1.4I-bluetooth (i-full duplex transmission) ubuchwepheshe bomsakazo obusekela imishini yokuxhumana kwebanga elifushane (< 10m);
ezintathu
1.5 I-IrDA (ifushane ngenhlangano yedatha ye-infrared, indinganiso ye-IrDA1.0 yakha uhlelo lokuvumelanisa lwe-serial nengxenye ye-duplex. Iphrothokholi yayo yedatha iqukethe izimiso eziyisisekelo ezintathu: ungqimba olubonakalayo, isendlalelo sokufinyelela kwesixhumanisi kanye nosendlalelo sokuphatha isixhumanisi. I-codec ye-IrDA IC kanye nabahlinzeki be-transceiver ikakhulukazi bahlanganisa Ti, ATMEL, NXP, Vishay, microelectronics ebukhali, Everlight electronics, Taiwan HL, Holtek semiconductor);
I-1,6 NFC (ubuchwepheshe bokuxhumana obungenawaya bebanga elifushane), ukuhlonza okungeyena othintana naye kanye nobuchwepheshe bokuxhumana, kuhlanganiswe nesifundi sekhadi esingenisayo, ikhadi le-inductive kanye nomsebenzi wokukhomba-kuya-iphuzu ku-chip eyodwa, ingakwazi ukuhlonza nokushintshanisa idatha namadivayisi ahambisanayo ibanga elifushane.Ibanga le-NFC licishe libe ngu-10cm,
ezine
1.7 Ubuchwepheshe bokuxhumana obungenantambo be-UWB
1.8 ubuchwepheshe be-linear frequency modulation spread spectrum
1.9 Ubuchwepheshe bokuhlonza ifrikhwensi yomsakazo we-RFID, obaziwa nangokuthi ubuchwepheshe bokuhlonza obungenawaya, buhlukaniswe okusebenzayo (ukuhlonza ibanga elifushane, ikhadi le-ID yesizukulwane sesibili, ikhadi lebhasi, ikhadi lokudla nekhadi lasebhange), i-passive (izinto zokuhamba ezihlakaniphile, indawo yokupaka ehlakaniphile) kanye imikhiqizo esebenza kancane (ihlanganisa izinzuzo zokusebenzisa nokungenzi lutho, i-trigger yefrikhwensi ephansi yokuma okunembile, ukuhlonza ibanga elide kanye nokulayishwa kwedatha)
amahlanu
2. Izidingo zokusebenza sezizonke
Izidingo zokusebenza eziphelele zifaka: amandla okucubungula idatha yokufaka, izidingo zokusebenza kwesistimu endaweni yokushisa neyomswakama, izidingo zesikhathi sokusebenza esingenaphutha nesizinzile sohlelo, izinga lokusebenza kahle kwamandla ohlelo kanye nokuzivikela. izidingo zohlelo
2.1 Izimfuneko zokusebenza kwedatha zihlanganisa umkhawulokudonsa omkhulu ongacubungula idatha, ukusebenza kwesikhathi sangempela sokucubungula idatha kanye nokunemba kokuqoqwa kwedatha,
2.2 Ngokuvumelana nezimo kohlelo endaweni, izinga lokushisa kanye nebanga lemvelo lomkhiqizo lizonqunywa esigabeni sokufunwa.Izinga lokushisa nemvelo yomkhiqizo ngu-0-70 鈩�, ibanga lezimboni - 40-85 鈩� kanye nebanga lezempi - 55-150 鈩�,
