摘　　要：在低速状态下经LPC2136普通单片机利用UART通信技术,通过对光电编码器的正交信号分析,来模拟正交编码器的硬件设计与软件设计,实现对电机转向及精确定位的数字化显示,为编码器应用在低速的自动智能控制领域提供了一个很好的解决方案。测试证实该设计对光电编码器的计数与标准记测器的计数值在低速旋转条件下非常准确。By orthogonal signal analysis of photoelectric encoder,hardware and software designs of the quadrature encoder are simulated at low speed by LPC2136 and UART communication technology to implement the digital display of precise posi-tioning of motor turning,which provides a good solution for encoder application in the field of low-speed automatic intelligent control. Testing result confirms that the design is very accurate in the count of the photoelectric encoder and count value of stan-dard measuring chronograph under conditions of low-speed rotation.
