摘要
Abstract
Aiming at the application scenario of wearable motion detection,a wearable walking step counting system based on FPGA-SoC and gyroscope sensor is designed.The system uses FPGA to realize the minimum system of E902 RISC-V processor as the main controller,and collects three-axis acceleration data in real time through MPU6050 sensor.In order to improve the data quality,firstly,the original acceleration signal is filtered by mean filter to eliminate noise interference.Secondly,the peak-valley detection algorithm is used to analyze the gait characteristics and implements the real-time judgment of the walking state.The experimental results show that the system has excellent real-time performance and high step accuracy,and can accurately identify the number of walking steps.This design gives full play to the parallel processing ability of FPGA-SoC,combined with the low power consumption characteristics of RISC-V processor,provides an efficient hardware solution for wearable motion monitoring equipment.The system has a compact structure and a simple and reliable implementation method.It is suitable for daily motion monitoring scenarios and has good practical value and application prospects.关键词
