Problems solved by technology

[0003] At present, CNC systems are mainly divided into PC-type CNC systems and embedded CNC systems. Compared with the two, PC-type CNC systems have a large number of redundant software and hardware, low real-time performance, high power consumption and low stability, while embedded CNC systems The data processing ability and module control ability of the system are relatively strong, however, the traditional embedded CNC system also has some defects, such as: the performance of the processor is not enough to support the execution of complex algorithms, and the physical communication sche

Abstract

The invention provides a multi-axis linkage embedded type digital control system and a development method thereof. The method comprises steps of constructing a hardware platform; designing a hardwarecircuit; transplanting an ARM-linux embedded real-time operation system, carrying out RTOS development on a multi-core processor; establishing communication between inner cores of the multi-core processor, establishing communication between the multi-core processor and an FPGA, developing firmware programs of a periphery circuit module and solidifying DSP, the FPGA firmware programs and the ARM application programs to the system. The digital control system comprises the multi-core process, the FPGA, a power supply module and the periphery circuit module based on FPGA expansion. The power supply module is connected with the multi-core processor, the FPGA and the periphery circuit module. The multi-core processor is connected with the FPGA. According to the invention, design difficulty levelof the system can be effectively reduced; development period is greatly shortened; and the system and the method help users to concentrate on solving specific application problems.
