The Design Of Portable Physiological Signal Monitoring System

Nowadays, people increasingly concerned about their health, the prevention of disease and health care have became an integral part of people’s life. In their own daily life, it is better to keep concerning about their physical condition rather than endure the pain and trouble when the disease is treated.Family Health Care Project as an emerging discipline, it has gradually go into people’s life as people take health seriously and the development of technology at home and abroad, which advocates "medical treatment at home, self-care, remote diagnosis", combining with the high-tech with medical treatment .This paper presents an effective and efficient monitoring program of physiology signal for the family and the community medical treatment. Protable physiological signal monitoring System is mainly designed for the terminal users. In order that people could monitor and analysis their own health condition, real-time understanding types of their body parameter information (such as ECG, respiration, body temperature, blood pressure, oxygen), at the same time display these parameter information in the form of digital and waveform on the instrument screen, and they can perceive various types of their own targets directly so that they make initial pathological diagnosis.Human health monitoring system includes the signal measurement part and display part. Measurement section includes a variety of surface probe components and measurement modules, the surface probe components include ECG Cable, blood pressure cuff, oxygen saturation, pinch probe, temperature probe, respiratory wave bands, and so on. Measurement modules include heart Electric acquisition modules, blood pressure acquisition modules, collection module oxygen saturation, respiration wave modules. Display part is the important point of this paper, using low-power ARM microprocessor control unit, low-cost Linux operating system, which real-time, reliable, widely used, easy development, multi-task. Interface development uses Qt/Embedded development environment, it supports application development framework at multi-operating system platform, which makes Unix, Linux operating systems develop a beautiful man-machine interface conveniently. The entire system focuses on the application technology of the ARM embedded microprocessor, Linux kernel transplant and application interface program development and sets out detail development processes .In the face of hardware and software, we do some corresponding handle to reduce power consumption in the embedded system and meet the needs of protable. Experiments demonstrate the feasibility and rationalization of the system design, and complete research and design from theory into practical application .This instrument has good practical values.
