摘要
实现了一种能对多种生理参数进行实时检测、存储、分析、显示及报警的嵌入式系统,采用S3C2440作为核心控制器,使用CAN总线实时传递生理参数信号,用WindowsCE作为操作系统协调软件界面与硬件的运作;图形用户软件界面考虑到生理参数数据量大,实时性要求高的特点,利用自定义的消息方式和多线程技术充分提高程序的实时性和代码的执行效率;程序运用面向对象的思想,便于后续功能的开发;通过和高实时性的PC测试程序波形比较表明,本系统具有很强的实时性和稳定性,可以实现预期的监测功能。
The paper achieved a kind of multi-physiological parameters collect and real-time display embedded system.CAN bus was used to transfer physiological parameter signal,WindowsCE operating system was used to co-ordinate software interface and hardware operations.Considered the huge data quantity and the high timeliness requirement,GUI used multi-threads technology and the custom message method to improve real-time property and the execution efficiency of the program.The project is programmed based on the object-oriented thinking,for the follow-up functional development.The Experiment uses test program based on PC which has high real-time capability to compare with this system.Results show that： the system has a strong real-time performance and stability,can achieve the desired monitoring functions.
