仰卧起坐计数器作为一种常见的计数工具,已经普遍的用于体育运动中。关于计数器我们都知道是用来计数的,而计数是一种最基本简单的运算,计数器就是实现这种运算的逻辑电路,计数器在数字系统中主要是对脉冲的个数进行计数,以实现测量、计数和控制的功能。本设计将计算机软、硬件技术溶为一体,以AT89C51单片机为核心,以光电传感器来实现对人体位置的检测,达到对仰卧起坐的自动计数。该设计实用可行,具有结构简单,实时性强,可靠性高等特点。
As a common counting tool, sit-ups countermeasures have been widely used in sports. We all know about the counter is used to count, and counting is a basic and simple operation, the counter is the logic circuit to achieve this operation, the counter in the digital system is mainly the number of pulses to measure in order to achieve measurement , Counting and control functions. The design of the computer software and hardware technology as a whole dissolved into the AT89C51 microcontroller as the core, the photoelectric sensor to achieve the detection of the human body position to achieve automatic counting sit-ups. The design is practical and feasible, with a simple structure, real-time, high reliability.
