The Research On Wearable Physiological Featuremonitoring Devices And Data Transmission Technology

The birth of wearable computing technology is mainly thanks to integrated circuits, embedded software and systems and the rapid development of semiconductor technology. As people living standard increases, the progress of science and technology and the embedded products are widely used in life, carrying out the research on the application of wearable computing technology has become the forefront of international computing important trend. This trend prompted us to re-examine the relationship between man and computer, further promote reflect contemporary human’s pursuit of "people-oriented" concept of the new man-machine relationship changes. One of the wearable computing purpose is the human body enhancements and auxiliary,combined with the characteristics of human physiological monitoring gradually become a hot topic in the study of scientific research. It has important application value in the sports fitness, health care and elderly guardianship. At the same time the wearable computing equipment need wireless communication technology to support its mobility,wearable and interoperability. Based on this background, this paper made the following several aspects work.First of all, on the basis of reading and referencing a large number of relevant literature,combined with the various characteristics of wearable computer, analyzing and comparing several commonly used short distance wireless communication technology, decided to use the bluetooth technology to build the wearable network;At the same time, design three application scenarios based on the sports fitness, health care and elderly guardianship, then proposed a wearable human physiological characteristics monitoring system three layer architecture, and introduce each layer. Under the framework, design and implemented a characteristics of wearable physiological monitoring system based on heart rate measurement, the wearable pulse signal acquisition device measures pulse wave signal data,and through the acquisition device built-in bluetooth module to transmit data to the Android mobile terminal,By 3G, 4G or WiFi technology data in real time or continuously sent to the remote server for storage, for further analysis and processing. Finally, detailed introduce the hardware system, software design and the structure of server.The purpose of this paper is to establish a monitoring system which used in wearable human physiological characteristics monitoring reference architecture, this paper pays attention to the sensor data acquisition and the realization of the bluetooth data transmission network with low consumption. Because the focus of the study lies in the scheme design, key technology and the implementation of the related function, the design schemes of the prototype unavoidably has many disadvantages. Partial results can provide certain reference value for further research.
