Research on Embedded Numerical Control System Hardware Platform Based on ARM9

This essay puts forward a multifunctional numerical control system, which is on the basis of ARM9 core microprocessor. It takes Samsung S3C2440A microprocessor as its operation core, in the pattern of dual-CPU, in order to automatically operate the processing. The control center plays the part of inputting the digital control program, keyboard inputting, LCD displaying, the explanation of the programs, crude interpolations and so on, with CPU as the assisting apparatus to realize fine interpolation. To expand the human interface and communication module, and fix an 8-inched multicolor display screen, in order to realize the human interface and communicate. The hardware platform is modularized, which makes the maintenance and upgrading of the system much easier. This system is low in power consumption and cost, which can realize many operations such as digital operation, combing shining metal and machine together, probing and so on; as a result, it is promising.
