Apejuwe fun CC2520
CC2520 naa jẹ iran keji ti TI ZigBee®/ IEEE 802.15.4 transceiver RF fun ẹgbẹ ISM ti ko ni iwe-aṣẹ 2.4 GHz.Chirún yii n jẹ ki awọn ohun elo ipele ile-iṣẹ ṣiṣẹ nipasẹ fifun yiyan ipo-ti-aworan / isọpọ-aye, isuna ọna asopọ ti o dara julọ, iṣẹ ṣiṣe to 125 ° C ati iṣẹ folti kekere.
Ni afikun, CC2520 n pese atilẹyin ohun elo lọpọlọpọ fun mimu fireemu, ifipamọ data, awọn gbigbe ti nwaye, fifi ẹnọ kọ nkan data, ijẹrisi data, iṣiro ikanni mimọ, itọkasi didara ọna asopọ ati alaye akoko fireemu.Awọn ẹya ara ẹrọ wọnyi dinku fifuye lori oluṣakoso agbalejo.
Ninu eto aṣoju, CC2520 yoo ṣee lo papọ pẹlu microcontroller ati awọn paati palolo diẹ diẹ.
1. Tani awọn oṣiṣẹ ninu ẹka R & D rẹ?Kini awọn afijẹẹri rẹ?
-R & D Oludari: ṣe agbekalẹ eto R & D igba pipẹ ti ile-iṣẹ ati ki o di itọsọna ti iwadi ati idagbasoke;Itọsọna ati abojuto ẹka r&d lati ṣe imuse ilana r&d ile-iṣẹ ati ero R&D lododun;Ṣakoso ilọsiwaju ti idagbasoke ọja ati ṣatunṣe ero;Ṣeto iwadii ọja ti o dara julọ ati ẹgbẹ idagbasoke, iṣayẹwo ati oṣiṣẹ ikẹkọ ti o ni ibatan.
Oluṣakoso R & D: ṣe eto R & D ọja tuntun ati ṣafihan iṣeeṣe ti ero naa;Ṣe abojuto ati ṣakoso ilọsiwaju ati didara iṣẹ r & d;Ṣe iwadii idagbasoke ọja tuntun ati daba awọn solusan ti o munadoko ni ibamu si awọn ibeere alabara ni awọn aaye oriṣiriṣi
R&d osise: gba ati too jade bọtini data;siseto Kọmputa;Ṣiṣe awọn idanwo, awọn idanwo ati awọn itupalẹ;Mura awọn ohun elo ati ẹrọ fun awọn idanwo, awọn idanwo ati awọn itupalẹ;Ṣe igbasilẹ data wiwọn, ṣe awọn iṣiro ati mura awọn shatti;Ṣe awọn iwadi iṣiro
2. Kini iwadi ọja rẹ ati imọran idagbasoke?
- Imọye ọja ati imọran ọja yiyan ati asọye ọja igbelewọn ati apẹrẹ ero akanṣe ati idanwo ọja idagbasoke ati ifilọlẹ afọwọsi si ọja
