Based On The Wavelet Denoising Micro-Pulse Wave Monitoring Device

Now, with upgrading people’s living standards, dietary changes in the structure and found that an increasing number of cardiovascular disease cases, people began to pay attention to their own health and health problems, while the pulse contains an important diagnostic parameter of cardiovascular disease, but worry about the large hospitals related equipment is large, expensive, and not conducive to family day-to-day care use, based on the pulse signal to design a small, portable pulse signal monitoring devices.In this thesis, completed the design and implementation of the overall design of the pulse signal monitoring system based stm32flO3ret6microprocessors and embedded technology, hardware, system and embedded operating system software, wireless GPRS wireless transmission technology to the traditional wired mode change mobile form of the measured patient data is continuously collected and this data in txt format, upload. Paper the history of the development of pulse signal detection, application and advantages and disadvantages in detail. Market advantages and development prospects of defects and a wide range of medical equipment to promote the use of the limitations of the system shows the subsequent chapters in more detail discusses the various parts of the system’s hardware and software design ideas and implementation methods.Based on the core of the pulse signal of the embedded technology of wireless monitoring system hardware is stm32flO3ret6microprocessors, the HK-2000B PVDF integrated pulse sensor collecting human pulse wave, stm32flO3ret6microprocessor internal AD converter, and wavelet denoising to filter the noise, via GPRS wireless transmission technology to upload data to the target computer and stored on the SD card memory. System software development platform based on μC/OS-Ⅱ embedded operating system, μC/GUI graphical user interface, transplantation and development of FATFS file system in stm32flO3ret6on the controller, according to the different tasks divided functional modules and write driver and application program, and after debugging and testing, the system is running stable. The text of the key and difficult programming of the pulse wave signal de-noising, and GPRS wireless transmission hardware and software implementation.Integration of embedded technology, real-time operating systems, digital signal processing technology, human-computer interaction technology for the monitoring instrument of pulse wave signal based on wavelet denoising, because daily phone GPRS technology is seldom used in medical monitoring equipment, which is a attempt. This design has a low-cost, small size, low power consumption, simple operation, etc. The compact design is easy to promote the use of a wide range in the field of medical monitoring equipment and community-based home health care equipment.
