Integrated Application Research About the Necklace Type Wearable Health Sensing System Under the Internet of Things

摘要

The Wearable Health Sensing System (WHSS) is to integrate the various sensors on the necklace, which is convenient for the real-time detection of human life and health, meanwhile to use the data processing ability of portable handheld terminal and coordination with the application of APP interaction to make the health assessment, diet care information pushing, and the emergency medical treatment true. This paper puts forward a scheme that integrating the multiple health sensors on the necklace, which includes the movement frequency, heart rate, sweat, skin tissue fluid, ECG, blood oxygen saturation, skin moisture, body fat, etc., objecting to setup a dynamic and collaborative monitoring physiological data under the daily life and the complicated working environment by means of a lower physiological and psychological load. Three modules are designed for WHSS: sensor integration module, power supply and power module, and signal integration and network transmission module. Corresponding sensors are chosen for WHSS according to various application requirements. Existing disturbances affect the accuracy and reliability of the judgment about the health feature points, accordingly the anti-interference processing is carried out. WHSS has only integrated multi-sensor without setting powerful data processing unit, so the captured signal is extended to handheld terminals to display and control in accordance with the processing ability of formalities terminal. The function model of data fusion system is setup, the level of the data fusion system is analyzed, the data fusion algorithm is realized, and the Multi-sensor system identification technology is studied. Due to the automatic comprehensive analysis capabilities of the multi-sensor system identification technology, it could be more effective and accurate to reflect the physical status of the object than any single sensor in the system. Under the environment of the Internet of things, the fusion of multiple data display control from WHSS, can accurately obtain the health information, and sets up the health system security network to a certain extent.
