Study Of Signal Measure And Communication Technology For Centralized Electrocardiogram Monitor System

The research on the biological medicine electric measurement and the monitor is the most basic and important research field in the biological medicine engineering, and it also closely connected with other branch of the biological medicine engineering. In the clinical medical treatment and monitor, auto-monitor is one of the most efficient means to get the physical information of the sufferer timely and to discover the accidental situation timely. It is also the most efficient way to deal with the accidental situation and to reduce the death rate in time. At present the monitor means used widely is the bedside-monitor of the doctor and the nurse. So it is very necessary and worthy to study an automatic, long-distance and concentrative monitor system.In the paper, the design scheme of the concentrative centralized electrocardiogram monitor system is proposed and the feasibility is analyzed on the foundation of domestic and abroad actuality study. At the same time, the design principle and method of every part in the system are also given. Several techniques, CAN bus, embedded Internet, wireless remote measure and data condensation, are used in the centralized electrocardiogram monitor system in this paper. The system can transmit the data of human physiology, such as cardiogram, respiration and blood pressure etc. and make the long distance and timely monitor and record by comparably low cost come true. The data can be used in computer's analyzing and the nosocomial staff's reference. This paper is mainly doing the following research:a) The practical plans of the electrocardiogram monitor-system are discussed.b) The characteristic of bioelectricity is discussed and the circuit, which is use to measure ECG is designed.c) The CAN communication technology is applied in nosocomial monitor system and CAN's adapter used to concentrative monitor system is designed.d) It is also discussed for the basic theory and the application scheme of short distance wireless communication.e) The way of ECG'S data compression applied to monitor-system is studied.f) The circuit about Wireless ECG data's transceiver is designed and the related running program of the embedded Internet model is written by using the C Program.g) The design and the debugging of the hardware are finished, which provides a better base for the product ulterior exploitation.
