Study the traditional way of data transportation in the CNC system, choose USB interface as data channel between master and slave machine, use the HPI interface of DSP chip to realize fast storage of mass data within slave machine. 对传统数控系统上下位机数据传输的方式进行了研究,确定采用USB接口作为数据的传输通道,并利用DSP芯片的HPI接口实现下位机内部数据的快速存取。
A model of master and slave control, which using PC based on Windows to storage data and compute and using the least system of single-chip to realize linkage and real time control of three-coordinate, is put forward. 提出了一种主从式控制模式,即用基于windows操作系统的台式机作为上位机,完成数据存储和复杂计算,用单片机最小系统实现多轴联动的实时控制。
In the slave system, native database storage module, Modbus/ TCP data processing module and exception handles module were designed in use of modularization idea. 对于子站,采用模块化设计思想,分别设计了本地数据库存储模块、远程数据传输模块、故障处理模块。
