A Novel Numerical Control Architecture based on Multiprocessor and Real-time Ethernet

摘要

The design of the CNC system to realize the function of the dedicated processor/modular is very select. Low cost of the ARM processor with Windows CE operating system is perfect for soft real-time tasks, such as the system state display, program explains, etc. The high performance DSP processors μ C/OS-II operating system is real-time tasks efforts, which is responsible for interpolation, speed control. In addition, to meet demand for the reconstruction of the design and flexible manufacturing, a reconfigurable based on FPGA technology for module, meet the functional requirement, build the PLC based on real-time Ethernet field bus network for simple connections between executors in the numerical control system controller.
