Electronic mankhwala R & D ndondomeko kumvetsera mawu
Popanga makina a hardware, mfundo zingapo ziyenera kumveka bwino:
1. Zofunikira pakugwirira ntchito:
1.1 mphamvu zamagetsi mode ndi chitetezo
Pali njira ziwiri: bolodi lopangira magetsi lomwe limapangidwira limaperekedwa mwachindunji kuchokera kumagetsi opangira magetsi kapena magetsi akunja oyendetsedwa ndi DC), bolodi lopangira magetsi lomwe limapangidwira limatengedwa, ndipo bolodi losinthira magetsi nthawi zambiri limayenera kupangidwa. mosiyana.Malinga ndi mapangidwe osiyanasiyana osinthira magetsi m'mafakitale osiyanasiyana, amayenera kupangidwa molingana ndi miyezo yosiyanasiyana yamakampani.Kunja kwamagetsi komwe kumayendetsedwa ndi DC kumatha kufewetsa gawo lamagetsi lamagetsi, Koma mufunika magetsi akunja.
Zida zowongolera mafakitale kapena zida zamankhwala ziyenera kuyendetsedwa ndi POE (mphamvu pa Ethernet).POE: ukadaulo womwe ulipo wa mphaka wa Ethernet 5 womwe ungapereke magetsi a DC pazigawo zina za IP (foni ya IP, malo ofikira a WLAN AP, kamera yama network, ndi zina zambiri) potumiza ma siginecha popanda kusintha kulikonse.IEEE 802.3af (voltage yotulutsa 44-57v ndi mphamvu yotulutsa 15.7w) ndiye muyeso woyamba komanso mulingo wokhazikika.IEEE 802.3at (magetsi otulutsa 50-57v ndi mphamvu zotulutsa 25.5w) amapangidwa ndi terminal yamphamvu kwambiri.
1.2 zolowetsa ndi zotuluka;
1.3 ntchito yolumikizirana opanda zingwe
Gprs-23bps ingagwiritsidwe ntchito ngati doko lachinsinsi mu gawo lotukuka la GPRS, ndipo imodzi ingagwiritsidwe ntchito mu module yolumikizana ya gprs-23bps, WiFi (ieee802.11x) ndiye muyezo waukulu waukadaulo wa WLAN pakadali pano.Kusunthika kwa WLAN kumathetsa zosowa za ogwiritsa ntchito mu 100m yomaliza.WiFi imapanga gawo lakuthupi (PHY) ndi media access control layer (MAC) ya protocol, ndipo imatenga TCP / IP ngati network network.
1.4bluetooth (full duplex transmission) ndi ukadaulo wapawailesi womwe umathandizira kulumikizana kwakanthawi kochepa (<10m);
atatu
1.5 IrDA (yachidule kwa infrared data organization, IrDA1.0 standard imapanga serial and half duplex synchronization system.) Dongosolo lake la data lili ndi ma protocol atatu: thupi, wosanjikiza wolumikizana ndi ulalo wowongolera. IrDA codec IC ndi ogulitsa ma transceiver makamaka akuphatikizapo Ti, ATMEL, NXP, Vishay, ma microelectronics akuthwa, Everlight electronics, Taiwan HL, Holtek semiconductor);
1,6 NFC (teknoloji yaufupi yolumikizirana opanda zingwe), chizindikiritso chosalumikizana ndi ukadaulo wolumikizirana, kuphatikiza owerenga makadi ochititsa chidwi, makadi ochititsa chidwi komanso ntchito yolunjika pa chipangizo chimodzi, imatha kuzindikira ndikusinthanitsa deta ndi zida zogwirizana. mtunda waufupi.Mtunda wa NFC ndi pafupifupi 10cm,
zinayi
1.7 UWB ukadaulo wolumikizirana wopanda zingwe wa UWB
1.8 liniya pafupipafupi kusinthasintha kufalikira sipekitiramu luso
1.9 RFID wailesi pafupipafupi chizindikiritso luso, wotchedwanso opanda zingwe chizindikiritso luso, lagawidwa yogwira (chizindikiritso zazifupi-siyana, m'badwo wachiwiri ID khadi, khadi basi, chakudya khadi ndi khadi banki), kungokhala (zoyendera wanzeru, wanzeru magalimoto) ndi zinthu zomwe zimagwira ntchito pang'onopang'ono (kuphatikiza maubwino achangu komanso osasunthika, choyambitsa chotsika pang'ono kuti muyike molondola, kuzindikira mtunda wautali ndi kukweza deta)

2. Zofunikira zonse zogwirira ntchito
Zomwe zimafunikira pakugwirira ntchito zikuphatikiza: mphamvu yopangira zolowetsamo, zofunikira pakugwira ntchito kwadongosolo pa kutentha ndi chinyezi, zofunikira za nthawi yogwira ntchito yopanda vuto komanso yokhazikika, kuchuluka kwamphamvu kwadongosolo komanso kudziteteza. zofunikira za dongosolo
2.1 zomwe zimafunikira pakugwirira ntchito kwa data zikuphatikiza kuchuluka kwa bandwidth komwe kumatha kusanthula deta, momwe nthawi yeniyeni yosinthira deta ndi kulondola kwa kusonkhanitsa deta,
2.2 pakusintha kwadongosolo ku chilengedwe, kutentha ndi mtundu wa chilengedwe cha chinthucho ziyenera kutsimikiziridwa pakufunika.Kutentha ndi chilengedwe cha mankhwala ndi 0-70 鈩�, kalasi ya mafakitale - 40-85 鈩� ndi gulu lankhondo - 55-150 鈩�,
