Path loss measurement method based on smart medical service

Abstract

The invention provides a path loss measurement method for intelligent medical service. The method is used for measuring the motion posture of a human body and comprises the following steps that the motion state of the human body is obtained, and human body modeling is carried out according to the motion state of the human body; in the human body modeling process, a complete motion posture is splitand divided into N theoretical frames, and all frame models are built; a body area network system is deployed according to a hierarchical structure, the body area network system comprises sensors andaggregators which are located at different levels, the sensors are used for collecting sign information of a human body, and the aggregators are connected with the sensors; data is tested, each sensor collects sign information and transmits the data to an aggregator, and the aggregator is used for collecting and centrally processing sign signals; and the aggregator processes the information and sends the information to a mobile phone or other terminals, so that doctors or family members of patients can know the information of related patients, and the patients can be monitored.

Description

technical field [0001] The invention belongs to the technical field of smart medical short-distance wireless channel research, and in particular relates to a method for establishing a path loss model of human motion posture in a distance Internet of Things environment. Background technique [0002] With the development and progress of technologies in the fields of sensing, communication and computers, wireless communication technology and low-power multifunctional sensors have developed rapidly, and miniature sensor nodes with perception, computing and communication capabilities have begun to appear. Multiple sensor nodes form various forms of wireless sensor networks through self-organization and dynamic configurability, which can be used to detect objective phenomena that people are interested in, such as humidity, temperature, pressure, and sound waves in the external environment. Because of its broad application prospects and its own unique characteristics, this wireless...
