1、本科毕业设计(20届)电子计步器摘要步行是一种最简单也是最好的健身锻炼方法之一。医学专家统计得出,现代人一天大约有300千卡的多余热量,如果每天步行一万步,就意味着可以把这些过剩的热量消耗光。而说时容易,做时难,没有量化的数据,指根据自己的感觉来判断运动量的大小是有欠缺的。这时需要一组数据来告诉我们运动量的大小,例如步数,路程,消耗的热量等。然而计步器就像一个贴身的健身教练,告诉你运动量的大小,指导你如何科学的锻炼。这样就保证了步行锻炼的质量,达到应有的健身效果。计步器系统主要是包括计数器和传感器。设计计数器,分别运用了数字电路和编程单片机两种方法。在数字电路设计方法中,运用74LS1
2、92,CD4511,CD4011和数码显示管组成了计数器电路,并通过protel进行计数器印刷电路板的设计。在编程单片机设计方法中,运用了C8051F000系统,并用C语言对其进行编程,实现计步数,计路程,计算速度,计算耗能并且通过数码管显示数据。设计传感器,主要研究了干簧管振动传感器的制作方法,了解了加速度传感器在计步器中的运用。关键词:科学步行锻炼;计步器;数字电路计步器;编程单片机计步器;AbstractWalkingisoneofthesimplestandbestfitnesstrainingmethods.Themedicalexpertcountsobtains,mode
