Application of RTOS to ECG tele-monitoring system based on mobile communication / 医疗卫生装备

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.
