【摘要】 随着健身人群的增加,安全事故频频发生。本文为了改善这一现状,基于ARMCortex-M4内核的STM32F407开发板,针对传统力量健身器械设计了力量辅助控制系统,以提升当下力量健身训练的训练效果,减少健身者在身边无人时存在的安全隐患。该系统主要由2部分组成:第一部分是由编码器来对器械运动状态进行识别与检测;第二部分是伺服电机驱动器的设计与实现。本嵌入式力量辅助系统实现了传统力量健身器械的功能提升,在训练者使用本器械时,能够提供实时的运动状态和进度反馈,若检测到训练者失力或力竭,则电机工作产生辅助力量帮助训练者完成训练,提升了训练的高效性和安全性。更多还原

【Abstract】 With the increase of fitness crowd,safety accidents occur frequently. In viewof this situation,this paper designs a strength assistant control system based on STM32 F407 development board with ARMCortex-M4 core,aiming at traditional strength fitness equipment,in order to improve the training effect of current strength fitness training and reduce the potential safety risks of trainer when there is no one around. The system mainly consists of two major components. The first part is the identification and detection of the motion state of the instrument by the encoder; the second part is the design and implementation of the servo motor driver.The embedded power assist system realizes the function enhancement of the traditional power fitness device,and provides real-time motion state and progress feedback when the trainer uses the device. And if the trainer is detected to be out of power or exhausted,the motor work produces auxiliary force to help the trainer complete the training,which improves the efficiency and safety of the training.更多还原
