过程装备中数据采集系统的低功耗设计

The Low-dissipation design of a data-acqusition system in process equipment

从理论分析和实际应用两个方面阐述和讨论了低功耗大容量便携式数据采集仪的研制方案。主要从芯片的选型、外围电路的设计、软件设计等方面入手来分析如何使电池供电的数据采集系统长时间工作于无人看管的场所。

This paper expatiates on the method of designing a portable and largecapacity microcontroller system with low power dissipation and discusses its development through both theoretic analysis and actual applications.Proceeding from the circuits,design,components and selection to software configuration,the paper analyses how the design conception can realize the function that keeps the batteryoperated dataacquisition system working for a long time at its working field without tenders.
