最小化物聯(lián)網(wǎng)傳感器節(jié)點(diǎn)功耗

　　由于有數(shù)十億的物聯(lián)網(wǎng)傳感器節(jié)點(diǎn)尚未部署，許多傳感器節(jié)點(diǎn)開(kāi)發(fā)面臨的關(guān)鍵問(wèn)題是電源。運(yùn)行這些傳感器的電力線是不切實(shí)際的，由于他們的位置，即使可行的，費(fèi)時(shí)和昂貴的。

　　此外，維修和更換電池可以大大降低業(yè)務(wù)案例。產(chǎn)品設(shè)計(jì)者需要要么無(wú)限延長(zhǎng)電池壽命，要么尋找替代設(shè)備來(lái)驅(qū)動(dòng)他們的設(shè)備。

　　本文將介紹如何分析一個(gè)產(chǎn)品的功耗和優(yōu)化其硬件和軟件，然后討論如何增加電池與最新的能量收集技術(shù)。

　　The energy profile

　　The key feature that designers need to examine and optimize is the energy profile for their product. The energy profile consists of：

　　Dynamic energy consumption： The energy consumed when the device is awake and operating

　　Static energy consumption： The energy consumed while the device is sleeping and not performing any work.

　　Designers have at least three options available that can be used to extend their battery life and minimize system maintenance：

　　Hardware energy optimization

　　Software energy optimization

　　Energy harvesting
