| 摘 要： | 对于开放式数控系统,它的控制软件全部在计算机中,硬件仅是计算机与伺服驱动之间的标准通用接口。为满足系统的实时性和可靠性,采用性能优越的IEEE1394总线连接计算机与伺服驱动。上位机以Windows+RTX(Real Time Extension)为平台,结合开放式主机控制器接口(OHCI)协议,实现了DMA方式的异步数据传输,并给出实验结果。

| Abstract: | As an Open Numerical Control(ONC) system,all the control softwares are put inside the computers and its hardwares are only universal interfaces between compters and servodrives.The IEEE1394 specification for a high performance serial bus interface is selected to connect compuer and servodrive for ensuring the real-time and reliability of the data transmission.Based on the platform of Windows+RTX(Real Time Extension) and combined with Open Host Controller Inerface(OHCI) protocol,asynchronous data trans-missi... |
