Research and development of embedded numerical control service system

Aiming at the inherent drawbacks of the traditional numerical control system based on industrial PC, the embedded numerical control service system based on Ethernet/Internet puts forward in the paper. The new system is constructed as a dual-CPU numerical control system, in which the ARM is defined as multi-machine NC management server that serve sharable functions for scheduling and execution control of machine tools, while the DSP can solve problems of high real-time demand by means of DSP's good real-time motion control function. The paper also introduces the hardware and software design in detail. The remote control and monitor was implemented based on B/S pattern. The result shows that this system has many advantages, including fully utilization of NC resource, reduce the system hardware scale, facilitate application development, cut down the costs, promote the system's reliability and ensure the real-time performance.
