摘要
在使用DNC技术实现数控设备的联网时,基于TCP/IP协议的工业控制以太网具有一定的性价比优势,但是对于只有串行通讯接口的老式数控设备来说,应用这一技术就存在一定的困难。利用TCP/IP到RS232接口转换器可以解决协议转换的硬件接口问题,但是在实现DNC高级控制中又存在传输数据速度匹配的问题,基于对该问题产生的原因分析,提出了一种延缓的方法。该方法能够通过丢弃当前数据包来解决上述问题,此法的可行性已得到了试验的证实。
While we use the network of DNC technology numerical control equipment, Ethernet of industrial control based on TCP/IP stack has certain cost and performance advantages, but to the outdated numerical control equipment with serial communication interface, applying this technology has difficulties. The TCP/IP to RS232 protocol converter can solve the problem of hardware interface, but the issue of velocity-matching exists in realizing the advanced control of DNC, analyzing on the reasons of the problem, I have put a kind of method to delay.This method can solve above-mentioned problems by losing present data program and is confirmed by test.
