農(nóng)村電網(wǎng)手持無線抄表器的研制

本文介紹了利用MSP430F149 單片機(jī)和nRF401 無線通信芯片構(gòu)成的低功耗手持無線抄
表器的軟硬件電路設(shè)計(jì)，設(shè)計(jì)中考慮到抄表要達(dá)到的“準(zhǔn)確、快速和全面”的目標(biāo)，也充分認(rèn)識(shí)到無線通訊所面臨的困難，同時(shí)也顧及到其作為一個(gè)即將推向市場(chǎng)的產(chǎn)品應(yīng)達(dá)到的要求，作者力求其既能可靠工作，又價(jià)格適中，功耗低，還便于操作和升級(jí)維護(hù)。

Abstract: This text is to introduce a portable wireless meter reading instrument which is made by microcontroller MSP430F149 and nRF401 and other components. The authors not only thought over the instrument should achieve the goal of “accurate, quick, overall”, but also took cognizance of the difficulty about wireless communication, at the same time, they gave consideration to the quality of the product which will face the market. They took their efforts to make it work reliably, cost moderately and be easy to operate and promote.
Keywords: MSP430F149,nRF401,low power, wireless meter reading instrument
