基于单片机的体育运动无线传感器网络性能比较研究

在体育运动中,尤其对于跳高运动中,起跳时的起跳速度和力是获得最大跳跃的两个主要参数,要测量这两个参数,需要包含微控制器和传感器的无线传感器网络(WSN)来分别描述跳线的速度和力的结果,从而对运动员运动能力的评价。比较了无线微控制器在吞吐量,延迟和成本,并且应用具有最佳性能和成本的微控制器设计并实现了新的跳高可穿戴设备。在实验中,集成了3个部件,即输入,处理和输出。通过对比,结果表明ESP8266微控制器在高吞吐量,低延迟和成本上有较高的性能。

In sports,especially in high jump sports,the takeoff speed and force during takeoff are the two main parameters for obtaining the maximum jump.To measure these two parameters,a wireless sensor network(WSN)including a microcontroller and a sensor is required to describe the results of the speed and force of the jumper.The two parameters can evaluate the athlete's athletic ability.This article presents a comparison of throughput,latency,and cost for wireless microcontrollers,and microcontrollers with the best performance and cost are determined to be used in the high jump wearable device.In the experiment,three components are integrated,i.e.,input,processing and output.By comparison,the results show that the ESP8266 microcontroller has high performance in high throughput,low latency and cost.
