摘要
针对X-Y平台,设计了一种分布式数控系统,基于主从式结构,以下位机作为主控制计算机,通过其ISA总线接口扩展的PCL-726和PCL-833卡实现控制信号输出和位置信号采集,利用上位机监控系统状态和实时调整控制参数,采用串行通信的方法实现上位机和下位机互相传输数据.实验结果表明该系统可靠性、实时性和稳定性良好.
Aiming at X-Y table, a kind of distributing numerical control system is designed, which is based on the master-slave structure. The master one is used as the main control computer. The slave one is used to supervise the system＇s states and adjust the control parameters. PCL-726 and PCL-833 cards fixed in the master one＇s ISA bus achieve the control signal outputs and feedback position signals, The data communication between the master one and slave one is based on serial interfaces. The result indicates that the system has good real time performance, reliability and stability.
