Research About Wireless Remote ECG Monitoring System Based On ARM9

With the development of technology, the improvement of people’s living standards and the increasingly fast pace of life, most young people suffer from more and more pressure. At the same time, the number of aging population is in a rising stage in China. Therefore, cardiovascular and cerebrovascular diseases have become the main killer murdered the inhabitants in our country. In the world, more than15million people were troubled by cardiovascular and cerebrovascular diseases. Therefore, how to discovery and treatment of cardiovascular and cerebrovascular diseases early has become the main research content of the medical field.This paper designed an intelligent, easy operation, safe and reliable ECG monitoring system, which is in line with the modern development trend. This system can meet the requirement for the people to find abnormal heart timely and take effective treatment measures.The system design of wireless intelligent monitoring system can realize real-time ECG signal acquisition, processing, display, storage, transmission, print and alarm when ECG abnormal. The system use S3C2440A, which is the core components of ARM9, as central control module.Using ADS1298chip as the ECG collection module.Using SIM900A module as the remote transmission module.Draw the circuit board of the system of professional, and add the USB serial port, SD card storage, LCD display and other external hardware module on this circuit board, build the system hardware platform. Then write LCD driver and SPI serial driver base on the hardware platform, next complete the embedded system Windows CE kernel customization and system migration work. Finally, achieve a writing system application software in the Windows CE6.0embedded operating system and the development environment Visual Studio2005. To meet the real-time requirement of the system, application program using multi-thread and a custom message technology to realize the basic function of ECG monitoring equipment in this system. In conclusion, this thesis designs an ECG monitoring system with friendly man-machine interface, easy to use, safe and reliable, which is can be applied to the family, community life, community health and other occasions. Finally, summarizing the research work and making the prospect on the future research, I believe that this thesis will make certain contributions to the field of medical care.
