AI Technical Summary

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 scheme between chips has lost data hidden dangers, the reconfigurability of the platform is not enough to realize the exchange between devices, the transmission rate of the communication interface is limited, the human-computer interaction is not intelligent enough, etc.

The above problems are not only caused by the hardware processor, but also have a great relationship with the designed CNC system structure, communication scheme, control algorithm, etc. Based on the above reasons, the development process of the traditional embedded CNC system is usually more complicated and the cycle is longer
