Cardiovascular disease is the number one killer that endangers human health in the world today. It is mainly caused by diseases such as hypertension and dynamic atherosclerosis. These diseases are not obvious in the early stage, but some related parameters have changed. Therefore, by detecting these parameters, the potential risk of cardiovascular disease can be diagnosed early, and the patient\'s condition and the degree of disease can be evaluated. Therefore, if these parameters can be checked in time, the potential risk of cardiovascular disease can be diagnosed early, which will gain precious time for its prevention and treatment. A large number of clinical test results have confirmed that the waveform characteristics of the pulse wave are closely related to cardiovascular disease. Therefore, the system detects cardiovascular parameters by detecting the pulse signal. Portable medical instruments have a large market, and medical instruments have shifted from traditional PCs and industrial control computers to embedded computer systems. With the increase in the computing power of microprocessors, ARM microprocessors and their superior performance will surely become the main platform for cardiovascular detection systems. This system uses Samsung ARM920 as a processor, collects pulse signals through pulse sensors, and is implemented based on an embedded Linux operating system. The system can display pulse wave waveforms in real time and select to display cardiovascular parameters. This paper elaborates on how to calculate cardiovascular parameters by detecting pulse waves; specifically analyzes the hardware platform of the system; mainly discusses the implementation of software, including the transplantation of bootload, the transplantation of embedded Linux system, and the transplantation of drivers; the writing of application programs; and the development of graphical interfaces based on QT. The use of high-performance ARM processors as the control core of the system can not only detect pulse signals in real time and analyze and process the signals, but also integrates a wealth of peripheral interfaces, which is conducive to the integration of the entire system. Further improving the accuracy of calculating cardiovascular parameters through pulse wave signals, the integration and miniaturization of the system, and further processing of parameter abnormalities are the development trends of future work. With the development of medical and health care, the prevention and treatment of cardiovascular diseases urgently need to be solved. Cardiovascular detection systems have a broad market space and are not only suitable for clinical use, but also for ordinary family applications.
