摘　　要：电子凸轮在自动化产品中的应用日益广泛。重点分析了电子凸轮曲线在ARM微处理器中的设计及实现方法,提出了一种能够稳定输出方波脉冲,并且速度无零点、无跳变的算法结构,实现了枕式包装机中电子凸轮控制横封切刀的柔性变速旋转。本方案解决了传统机械凸轮安装困难、响应滞后、量测性差、成本较高等问题,采用色标传感器和编码器对包装长度和速度进行反馈,提高了包装精度,减少了系统的响应时间。Electronic CAM is increasingly used in automation products. This paper mainly analyzes the design and implementation method that electronic CAM curve realizes in ARM microprocessor, and puts forward an algorithm structure which can output square wave pulse, whose speed without zero point and jumping. Flexible variable speed rotation movement control of the horizontal sealing and cutting knife in the pillow packaging machine is realized. This solution solved the problems in traditional mechanical CAM such as difficult installation, lags in response, bad measurement performance and the high cost. It uses color sensor and encoder to detect the feedback of packaging length and speed,the packaging precision is improved and the system response time is reduced.
