Sports training monitoring of energy-saving IoT wearable devices based on energy harvesting

Abstract

In this paper, energy-saving the Internet of Things wearable devices based on energy harvesting used to monitor sports training. The energy sources involved include radiofrequency energy, mechanical energy, and thermal energy. The power management circuit structure designed to match its application with energy harvesting components as the core to ensure that the collected energy can meet the power conditions of electrical equipment. Completed the hardware design of the entire human motion information collection system based on energy-saving IoT wearable devices, first gave the overall design plan of the system, and on this basis, adopted the modular design of the system, and designed the posture measurement separately unit, positioning unit, and data storage and communication unit. Among them, the attitude measurement unit designed according to the different needs in actual use, and the miniature attitude measurement unit and the multi-function attitude measurement unit are designed. The data storage and communication unit designed to ensure data storage and for the reliability of transmission, an offline data storage unit and a Bluetooth remote communication unit designed respectively. The system adopts a modular design, which makes the system more convenient to expand and upgrade, and has better applicability and reliability.
