Abstract


Cardiovascular disease is the number one killer in the world today hazards to human health , mainly caused by high blood pressure and dynamic atherosclerosis and other diseases , the early these diseases is not obvious , but some parameters have changed . Therefore , these parameters by detecting early diagnosis of the potential risk of cardiovascular disease , can also assess the patient's condition and indicates the extent of the disease . If you could check these parameters on early diagnosis of the potential risk of cardiovascular disease , its prevention and treatment to fight the valuable time . The large number of clinical experimental results confirmed the characteristics of the waveform of the pulse wave is closely related to cardiovascular disease . Therefore, the system is detected by detecting the pulse signal to the cardiovascular parameters . Has a very large market , portable medical equipment and medical equipment from the traditional PC and industrial control computer steering embedded computer systems . With the increase in microprocessor computing power , ARM microprocessor and its superior performance is bound to become the main platform for cardiovascular detection system . The system uses Samsung ARM920 processor , pulse sensor to capture the pulse signal , and embedded Linux - based operating system to achieve . The system pulse waveform can be displayed in real time , select Show cardiovascular parameters . This paper elaborates how to calculate cardiovascular parameters by detecting the pulse wave ; detailed analysis of the system 's hardware platform ; mainly discusses the software implementation , including the bootload transplantation , transplantation of embedded Linux system , driver transplantation ; application preparation ; QT - based graphical interface development . The high - performance ARM processor as the core of the system of control , not only real-time detection of pulse signal analysis and signal processing , and integrated rich peripheral interface conducive to the integration of the entire system . Further improve the cardiovascular parameters calculated by the pulse wave signal accuracy , system integration and miniaturization , the exception processing parameters further processing is the development trend of the future work . With the development of medical and health services , prevention and treatment of cardiovascular disease need to be resolved , cardiovascular detection system has a broad market space , not only suitable for clinical use , and is also suitable for the application of ordinary families .
