The Multitask Design Of Monitoring Terminal

As a new pattern of medical treatment that can provide community residents with convenient, economical and effective medical service, the community service system of medical treatment has been developed gradually. However, there are no suitable devices and equipments. Now, telemedicine technology, which combines computer technique, communication devices and Internet technique, has been paid importance and recognized by increasing specialists. This paper introduces a terminal of ECG monitor system based on mobile communication network, which is designed for the community medical treatment system .The main function of the system is to gather, to process and to store ECG signals. When there are abnormal ECG signals, the system will transmit the data to the service center and realize the long-distance real-time monitor to the patients. The monitor terminal consists of three parts, the DSP system that gathers and processes the data, the main controller system that stores and displays the data and the wireless transmitter system that transmits the ECG signals to the service center. The system has keyboard and LCD, which facilitates the costumer. When DSP detects the abnormal ECG signals, the system will alarm and communicate with service center by mobile network, which makes the patients to be assisted by the doctors as soon as possible. The main controller system is the core part of the monitor terminal. The paper research the hardware and software design. The main controller system is made up with some circuits. It is divided into multitasks according to the different circuits. In order to meet the requirement of real-time, the main controller system is managed by the real-time operating system uC/OS-II.
