摘　　要：本文介绍了一种多参数低功耗监护仪的研制,以高性能AT91SAM9261为核心,包含心电、血氧、血压、呼吸率、体温等多参数采集模块,数据存储模块,人机交互模块,联机通信模块,打印模块等。它基于uC/OS-Ⅱ操作系统,移植了uC/GUI图形界面软件包来支持界面设计,并移植了YAFFS2(Yet Another Flash File System 2)文件系统来管理用户资料和数据。此监护仪具有功耗低、低成本、实时性好、功能齐全等优点。The development of a multi-parameter and low-power monitor is discussed in this paper.The monitor equips an AT91SAM9261 microprocessor as its main controller and contains multi-parameter signal collecting module,data storage module,human-computer interaction module,online communications module and printing module.The whole software system is based on the uC/OS-Ⅱ equipped by uC/GUI,which is used to facilitate interface design.At the same time,for the convenience of data management,a YAFFS2 file system is transplanted.The monitor has the advantages of low consuming,low cost,real-time control and multi-functions.
