摘　　要：针对家庭护理问题,设计并实现了基于CAN总线的嵌入式智能防褥疮气垫床。阐述了该智能气垫床的硬件系统设计,软件系统设计及实现方法。气垫床控制模块由AT90CAN128单片机、气垫床、压力传感器、气泵和电磁阀门等构成。采用S3C2440作为主控制模块,以WindowsCE操作系统为核心开发的人机交互界面(HMI)通过CAN总线实时传递各个功能模块命令,能够实现气垫床的预定功能,给出了实验实测数据,并且能够实现即插即用的模块化设计。For home nursing problems, embedded intelligent anti-decubitus air cushion bed is designed and implemented based on can bus. This text expatiates the design of hardware system of smart air cushion, design of software system and realization process. Air cushion bed control module is composed of AT90CAN128 SCM, air cushion bed, pressure sensor, air pump and electromagnetic valve and other accessories. S3C2440 is used as the main control module, WindowsCE operating system as the cote to the development of humanmachine interface, send each module command in real time through can bus, achieve the predetermined function of air cushion bed, experimental measured data are given and it can realize the modular design of plug and play.
