Abstract

The invention belongs to the technical field of positioning and the field of mode recognition, and provides a self-adaptive human behavior data acquisition and recognition system and method based on UWB and LoRa. The system comprises an inertial data acquisition module which is used for sensing motion data of a user; a physical sign data acquisition module which is used for sensing physical sign data of a user; an intelligent sensor scheduling system module which is used for regularly acquiring and processing user motion data and physical sign data and adaptively sending the data to the data transmission base station module in a UWB or LoRa communication mode; a data transmission base station module which is used for forwarding the received data to the server-side processing program module; and a server-side processing program module which is used for resolving the data sent by the data transmission base station, storing the resolved data, carrying out human body behavior identification by utilizing the resolved data and a human body behavior identification model, and outputting the user position information and the behavior category information together if the resolved data contains the positioning information.

Description

technical field [0001] The invention belongs to the field of positioning technology and the field of pattern recognition, in particular to a UWB and LoRa-based adaptive human behavior data collection and recognition system and method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The sensor-based human behavior recognition system is a system that collects behavior information through various sensors and realizes behavior recognition through a reasonable classification model in the process of various human behaviors. With the development and maturity of communication technologies such as 5G and WiFi, artificial intelligence technologies such as machine learning and deep learning, and indoor positioning technology based on Ultra Wide Band (UWB), behavior recognition combined with location information will also become a key issue. research...
