Zvinodiwa zvekushanda

Electronic chigadzirwa R & D maitiro ekuteerera inzwi
Paunenge uchigadzira Hardware system, akati wandei mapoinzi anofanirwa kuve akajeka:
1. Zvinodiwa zvinoshanda:
1.1 magetsi ekupa maitiro uye kudzivirira
Kune nzira mbiri: iyo yakavakirwa-mukati magetsi emagetsi bhodhi inopihwa zvakananga kubva kune mains magetsi emagetsi kana yekunze DC inodzorwa magetsi), yakavakirwa-mukati magetsi bhodhi inogamuchirwa, uye switching magetsi emagetsi bhodhi kazhinji inoda kugadzirwa. zvakasiyana.Zvinoenderana neakasiyana madhizaini ekuchinja magetsi mumaindasitiri akasiyana, inofanirwa kugadzirwa zvinoenderana neakasiyana indasitiri zviyero.Iyo yekunze DC inodzorwa magetsi inogona kurerutsa chikamu chemagetsi chikamu chehardware system, Asi iwe unoda kunze magetsi ekupa.
Midziyo yekudzora maindasitiri kana michina yekurapa inoda kufambiswa nePOE (simba pamusoro peEthernet).POE: iripo katsi Ethernet 5 tekinoroji iyo inogona kupa DC magetsi ezvimwe IP-based terminals (IP foni, WLAN yekupinda nzvimbo AP, network kamera, nezvimwewo) uchitumira masaini pasina shanduko kune zvivakwa.IEEE 802.3af (kubuda kwemagetsi 44-57v uye simba rekubuda 15.7w) ndiyo yekutanga chiyero uye chiyero chekushandisa.IEEE 802.3at (output voltage 50-57v uye simba rekubuda 25.5w) inogadzirwa nepamusoro-simba terminal.
1.2 zviratidzo zvekupinza uye zvinobuda;
1.3 wireless kutaurirana basa
Gprs-23bps inogona kushandiswa seserial port mune yakagadziridzwa GPRS module, uye imwe inogona kushandiswa mune yakagadziridzwa gprs-23bps communication module, WiFi (ieee802.11x) ndiyo huru yehunyanzvi chiyero cheWLAN parizvino.Iko kutakurika kweWLAN kunogadzirisa zvinodikanwa zvekutaurirana zvevashandisi mune yekupedzisira 100m.WiFi inogadzira iyo yemuviri layer (PHY) uye midhiya yekuwana control layer (MAC) yeprotocol, uye inotora TCP / IP setiweki layer.
1.4bluetooth (full duplex transmission) tekinoroji yeredhiyo inotsigira midziyo yenguva pfupi yekutaura (<10m);
tatu
1.5 IrDA (ipfupi ye infrared data organisation, IrDA1.0 standard inogadzira serial uye hafu duplex synchronization system. Iyo data data protocol ine matatu akakosha maprotocol: body layer, link access layer uye link management layer. IrDA codec IC uye transceiver suppliers inonyanya kusanganisira Ti, ATMEL, NXP, Vishay, microelectronics inopinza, Everlight electronics, Taiwan HL, Holtek semiconductor);
1,6 NFC (pfupi-renji isina waya yekutaurirana tekinoroji), isiri-yekuzivikanwa chitupa uye yekubatanidza tekinoroji, yakasanganiswa ne inductive kadhi muverengi, inductive kadhi uye point-to-point basa pane imwechete chip, inogona kuona uye kuchinjanisa data nemidziyo inoenderana mu. chinhambwe chipfupi.Nhambwe yeNFC inenge 10cm,
ina
1.7 UWB isina waya inotakura kutaurirana tekinoroji
1.8 mutsara frequency modulation kuparadzira tekinoroji tekinoroji
1.9 RFID redhiyo frequency identification tekinoroji, inozivikanwawo sewaya yekuzivikanwa tekinoroji, yakakamurwa kuita inoshanda (pfupi-renji chiziviso, chizvarwa chechipiri ID kadhi, kadhi rebhazi, kadhi rekudya uye kadhi rebhangi), passive (yakangwara yekufambisa, yakangwara yekupaka) uye semi-inoshanda zvigadzirwa (kusanganisa mabhenefiti ekushanda uye kungoita, yakaderera-frequency trigger yekumisikidza chaiyo, chitupa chekureba uye kurodha data)

2. Zvose zvinodiwa zvekuita
Izvo zvese zvinodikanwa zvekuita zvinosanganisira: kugona kugadzirisa kwedata rekuisa, zvinodiwa zvehurongwa hwekushanda pane tembiricha uye humidity nharaunda, zvinodiwa zveisina kukanganisa uye yakagadzikana nguva yekushanda yehurongwa, giredhi rekushandisa simba rehurongwa uye kuzvidzivirira. zvinodiwa nehurongwa
2.1 iyo inodiwa yekushanda kwedata inosanganisira yakakura bandwidth inogona kugadzirisa data, chaiyo-nguva kuita kwekugadzirisa data uye iko kuunganidza data,
2.2 yekuchinjika kweiyo sisitimu kune zvakatipoteredza, tembiricha uye giredhi yezvakatipoteredza yechigadzirwa ichatemwa mudanho rekudiwa.Iyo tembiricha uye giredhi yezvakatipoteredza yechigadzirwa ndeye 0-70 鈩�, giredhi reindasitiri - 40-85 鈩� uye giredhi remauto - 55-150 鈩�,
