VIRTUAL UPPER COMPUTER-BASED NUMERICAL CONTROL SYSTEM

摘要

A virtual upper computer-based numerical control system comprises a virtual upper computer provided on a remote server, a lower computer of the numerical control system which is located locally and a human-machine interaction device for human-machine interaction, wherein the human-machine interaction device is used for providing a human-machine interaction input/output interface; a human-machine interaction module, a non-real time/half-real time task execution unit and a lower computer control unit are integrated on the virtual upper computer, and the upper computer receives a numerical control machining instruction and processes same via the non-real time/half-real time task execution unit to form a machine tool control instruction, so as to transmit control data to a local lower computer by means of the network via the lower computer control unit; and the local lower computer controls a machine tool to execute real-time motion control and logic control. The system realizes a new design of the architecture of the upper and lower computers of the numerical control system based on a virtualization technology, and solves the problem of limitations on a data processing capability, HMI function extension and remote machining which are present in the numerical control system at present.
