摘　　要：针对未来跑步机系统对智能化、数字化、人性化的需求,提出了一种以STM32微控制器为控制核心的基于嵌入式技术的智能型跑步机控制系统。该系统除了能够对跑步机速度、运动状态等基本功能进行稳定的控制外,还具有语音控制、音乐播放、LCD显示、心率运动指导控制等智能化功能。系统的硬件部分给出了硬件结构框图并简单介绍了STM32微控制器、电源电路、反馈电路,着重介绍了调速电路、以LD3220为控制核心的语音识别和播放电路;软件部分给出了主程序设计流程图、语音识别子程序设计的流程图以及PWM输出子程序的设计方法。通过对部分核心硬件电路及软件程序的实验,验证了系统的可行性及稳定性。In view of the position intelligence,digitalization,hommization requirements to the treadmill control system, a novel put forward a intelligent treadmill control system based on STM32 micro-controller. The system has function of controlling the speed of treadmill,state of motion and some basic state steadily,but also has intelligent function such as voice control,voice playing,LCD displaying, energy saving control and so on. The hardware of system gives hardware structure diagram and briefly introduces STM32 micro-controller, power circuit, feedback circuit, and specifies speed regulation circuit, voice recognition and voice playing circuit based on LD3320; the software of system gives the designation method of flow chart of main program,voice recognition program and PWM output. Through the experiment to partial core hardware circuit and software program provides feasibility and stability of the system.
