Embodiment Construction

[0013] 1 Human body sensor network protocol

[0014] Due to the characteristics of ultra-low energy consumption, low complexity, unpredictable transmission duty cycle, and data transmission between heterogeneous nodes, the traditional sensor network media access control (MAC) protocol has been unable to meet its special requirements. . Therefore, in this project, IEEE 802.15.4 will be combined with UWB to develop an ultra-low energy MAC protocol for biomedical sensors. IEEE 802.15.4 is an open standard designed for low power consumption, low data rate networks. However, it does not have the flexibility to handle special application requirements while ensuring compatibility. The goal of our research is to design a flexible and IEEE 802.15.4 compliant body sensor network MAC protocol (B-MAC). It can meet the special requirements of human body sensor network. The key technology is to adjust its parameters adaptively in order to reduce the energy consumption of the network.

Abstract

The invention relates to a wearable body sensor network human body monitoring system used for monitoring the physical health of mothers and infants in real time. The wearable body sensor network human body monitoring system can carry out monitoring and pre diagnosis according to vital sign parameters. Anti-interference design is adopted, radio interference between sensor nodes and between the sensors and an external environment can be deceased, so that the reliability of the system can be improved. Based on the combination of sensor technology, wireless data transmission technology and computer network technology, mother and infant wireless monitoring waistcoats rapidly detect electrocardiogram and body temperature signals of the mothers and the infants; and the human body feature parameters of the mothers and the infants, such as heart rates and body temperature, which reflect physical health, are displayed timely and transmitted to medical equipment through a local communication node so as to be analyzed and evaluated. The low-cost and low-energy consumption wearable sensor nodes with interconnection capability are designed, and a data analysis algorithm for processing and analyzing data returned by the nodes is developed, and therefore, early judgment on the complications of pregnancy can be realized. Interference in the wearable sensor network is researched, so that radio interference between the sensor nodes and between the sensors and the environment can be decreased.
