Design of Infant Gait Monitoring System Based on FPGA

Abstract

In recent years, the incidence of abnormal leg types such as foot internal rotation, foot external rotation, partial flat foot and O-shaped leg is very high among teenagers and children in China, which has a serious impact on the growth of teenagers. Gait monitoring system is used to detect whether children’s walking posture is correct or not. Because of its good portability, low cost and accurate measurement, it is widely used in the medical field. This paper designs a gait monitoring system for young children based on domestic FPGA, which is designed by Chinese. The 32-bit SOC architecture with Cotex-M3 as the core is used as the controller. The gait information is obtained through mpu6050 sensor, and then the controller calculates and processes the collected data. The data calculated by attitude angle is uploaded to the cloud platform through WIFI module. After obtaining the data, the upper computer displays the angle offset value. At the same time, when the measurement angle is higher or lower than the set threshold, the system alarm device will be triggered. The hardware structure of the system is simplified, which can meet the high-speed data transmission work, and provides a more stable and accurate reference standard for attitude information.
