Abstract Household multifunctional treadmill is a fast, convenient, safe and reliable indoor fitness equipment.With the health awareness and the pursuit of high quality of life, multifunctional treadmill function more perfect and powerful. The design task to use have learned of the circuit and the graphics programming knowledge to master the design principle and the design scheme of treadmill.And can design the hardware structure diagram, circuit diagram and software design flow chart.CAD were used in the design drawing some of the parts and the overall structure of the design,By using the circuit knowledge layout and wiring,Finally the use of programming knowledge simulation.Domestic and foreign brand structure and style in the design of reference,step on the treadmill has deep knowledge and understanding.Due to the special nature of home treadmill, safety and maintenance and repair is also very important. Thesis based on functionality requirements treadmill drive control system, given the overall design.Focus on the inverter and the drive circuit,Analysis of the bootstrap drive problems:Determined to μPD78F1213 microcontroller as the core circuit,Intelligent module (IPM) inverter circuit as the core of the basic hardware architecture.
Key words:treadmill Single chip microcomputer Frequency converter Speed control

1 绪论 1.1跑步机的背景 随着社会的进步，经济的飞速提升，人们改变了固有的消费方式，开始对健康越来越重视。人们意识到要用体育锻炼来改善这一情况，而跑步作为国际流行并被医学界和体育界高度评价的有氧运动，是人们最常用的锻炼方式之一[1]。但是由于环境天气的影响，户外运动有着一定的局限性，因此跑步机的出现很大程度的解决了这一困扰。 特别是多功能跑步机结合了跑步机，卧式健身，立式健身，放松机和腰旋器等功能，以功能多和占地少倍受欢迎。 然而怎样才能利用跑步机的全功能为我们服务呢？运动时，跑步机电子屏幕会显示时速，时间，心率，热量，节拍，距离等指标。理解显示的意义就可以更好的及时观察自身状况。
