本课题探究的是铅球声音信号信息反馈设备,可以在铅球的内部放置一个电子压力的装置,然后再根据这个非电量测量的原理来解析并最后得到一个我们需要的信号。在本课题里是对声音信息反馈设备从这个声音信号的预处理到反馈设备的一个整体设计探究,并且对于铅球的一个内部压力检测的装置还有实现测量的原理分析。铅球声音型号信息经过放大以及采样还有数模转换的过程,最后把这个转换而来的数字信号传入电脑里,这些信号通过计算机的进一步解析之后,也就自然可以推算出铅球被推出去的过程,并且做出这些信息的一个反馈。
This topic explores the feedback signal of shot-put sound signal, which can put an electronic pressure device inside the shot-put, and then according to the principle of non-power measurement, we can get a signal that we need. In this project, we study the overall design of the feedback device of sound information from the preprocessing of this sound signal to the feedback device, and an internal pressure detection device for shot put has the principle analysis of realizing measurement. Shot put sound model information after amplification and sampling there are digital to analog conversion process, and finally the converted digital signal into the computer, these signals through the computer after further analysis, it can naturally calculate the shot put to go Process, and make a feedback on this information.
