基于WinCE的超声乳化仪多串口通信

Multiple serial-port Communitication of Phacoemulsifier Based on WinCE

超声乳化仪属于医疗行业三类产品,对系统实时性、稳定性要求极高、任务较复杂,给设计工作带来一定的困难。在WinCE多线程及其调度机制的基础上,一种新的适用于复杂任务实时系统的软件架构设计方法成功地运用到设计中,完成多串口分层流驱动的设计,并以眼科医疗产品——超声乳化仪为背景,分析了相关系统模型和程序代码。

The phacoemulsifier is class III equipment in medical equipment,the higher real-time capability requirements and the more complex tasks for Phacoemulsifier system present many problems to the designing.Based on the analysis on Windows CE multithread techniques and it＇s dispatching mechanism,a new software architecture designing method is presented and applied successfully to the design,which is suitable for the complex real-time application.The design of layered-flow device driver of multiple serial-port.This paper also gives some code of system.
