Abstract


The rapid development of today's society greatly increase people's material standard of living, and was followed by the accelerated pace of life and the pressure of living increases. These are made rapid surge burst rate of heart disease, heart disease has become one of the biggest killers of human health. ECG examination, diagnosis and prevention of heart disease and other major means of these diseases and the basis for the use of ECG monitoring throughout the treatment, rehabilitation of the whole process, which has a reliable diagnostic method is simple, no harm to the patient the advantages of the modern medicine, is becoming increasingly important. Doctor can electrocardiographic analysis of the human body to the heart lesions of diagnosis and treatment. The main research work includes the following: (a) a portable ECG monitoring system hardware development and implementation. According to ECG feature, choose appropriate design parameters of the electronic devices ECG acquisition front-end amplifier module, complete the weak signal amplification; basis of biological signals in the frequency range design hardware filter circuit and the AD converter; and heart rate parameter detection is achieved. After the preparation of the display to achieve ECG heart rate and heart rate driven algorithm written. Body temperature detection is achieved. Including the choice of components to measure body temperature, body temperature and the temperature of the hardware circuit preparation of the driver, the last in reality a touch screen temperature parameters; while achieving hyperthermia alarm system. Blood Pressure implementation. The first is based on the principle of selection components generate blood pressure, blood pressure, as well as the hardware circuit preparation of the driver, as well as the final results are displayed. Use high-performance, low-power ARM processor S3C2440, the collected signal analysis and recording while using the touch screen as an interactive interface to provide users with an interface. (2) embedded operating system and its associated drivers transplant implementation. According to the characteristics of S3C2440 processor BootLoader select the appropriate compiler transplantation; embedded Linux kernel were studied, corresponding to the ARM platform and made the appropriate changes, completed the transplant; construct the file system, and the establishment of cross-compiler environment, Transplant corresponding library; under Linux device driver model was designed and implemented LCD, ADC driver. (3) the use of Qt / Embedded embedded interface. Portable ECG monitoring system based on functionality, design appropriate graphical interface.
