摘要：为了解决总线模式数控系统中手轮信号采集、传输难的问题，采用了一种新型的手轮连接方式，即通过工业计算机现有的串口读取手轮的脉冲信号，经特定程序识别处理后，交由数控系统内核以完成相应的运动控制。实验结果表明，利用串口实现手轮连接，不仅能够达到传统连接方式下手轮工作的全部性能指标，而且能减少硬件数量，降低系统成本，简化系统结构，有利于进一步提高系统的可靠性。

Abstract: Aiming at the difficulty of handwheels signal collection and transmission in CNC bus mode system, a new type of handwheel connection was used to read the handwheel pulses signal through the serial port of industrial computer, the signal was sent to the CNC system kernel and executed the corresponding motion control after a specific procedure. The results indicate that this method not only can work well compared with the traditional communication, but also reduce the number of hardware and cost, simplify the system structure, and it can be conducive to further enhance the reliability of the system.
