实时操作系统在远程心电监护系统中的应用

Application of RTOS to ECG tele-monitoring system based on mobile communication

介绍了实时操作系统μC/OS-Ⅱ在一种远程心电监护系统中的应用。讨论的系统由监护终端和监护服务中心2部分构成,监护终端具有心电数据采集、数据实时分析和存储、键盘控制和液晶显示管理、系统监控以及心电信号网络传输等功能。这些功能的时程安排各不相同,单任务管理无法实现这些功能,因此,采用多进程管理技术。在Rabbit2000主控制器中我们采用了实时操作系统μC/OS-Ⅱ来管理多任务。

In this paper, the application of 霤/OS-II, one of the real-time oper ation systems (RTOS), to ECG tele-monitoring system based on mobile communicatio n is introduced. The system is composed of monitoring terminals and a monitoring center. The terminals have functions such as ECG data acquisition and storage, real-time data analysis, keyboard input, LCD display, system monitor and automat ic transmission of abnormal ECG data to the monitoring center through mobile com munication network. Because these functions are not executed simultaneously, mul ti-task management is adopted instead of single task management. In Rabbit2000 m ain controller, 霤/OS-II is applied to multi-task management.
