提出一种牛顿第二定律智能验证仪的设计方案并予以实现。在对传统实验装置与小车运行状态的关系进行分析的基础上,对传统实验装置进行改进,增加了数据采集、智能控制和显示模块,实现了平衡状态的自动调整、实验数据的自动采集与分析、数据结果的图形化展示等功能。验证仪的智能化、自动化可以使学生专注于对定律的理解,提高实验效率。该验证仪有效削弱了人为因素带来的影响,使得实验数据更为准确。实验数据的智能化分析与图形化展示,对深刻理解牛顿第二定律有着重要意义。
A design scheme of Newton’s second law intelligent verifier is proposed and implemented. Based on the analysis of the relationship between the traditional experimental equipment and the running status of the trolley, the traditional experimental equipment is improved, the data acquisition, intelligent control and display module are added, the automatic adjustment of the balance state, the automatic acquisition and analysis of the experimental data are realized , The data results of the graphical display and other functions. The intelligence of the verifier, the automation can make the student concentrate on the understanding of the law, improve the experiment efficiency. The validator effectively reduces the impact of human factors, making the experimental data more accurate. The intelligent analysis and graphical display of experimental data are of great significance to the profound understanding of Newton’s second law.
