Implementation method for networked system structure of numerical control system

Abstract

The invention discloses an implementation method for a networked system structure of a numerical control system. The implementation method comprises the following steps of: separating a human-computer interface controller from a numerical control machine to run in an industrial personal computer (PC), and making a task controller, a motion controller and a programmable logical controller (PLC) run in the numerical control machine; implementing real time data processing of the human-computer interface controller through a soft real-time mechanism on the industrial PC; implementing real time data processing of a server and the task controller through a soft real-time mechanism on the numerical control machine, and communicating the task controller with the motion controller by using a mixedinteractive model; and connecting the industrial PC with the numerical control machine through a real-time Ethernet. By using the implementation method, the pressure of a processor can be relieved, the control performance of the numerical control system is improved, the real-time property of data transmission among cross-platform modules is ensured, and a speed of data processing of a user task, the data interactive performance among local modules and the stability of the system are improved.

Description

technical field [0001] The invention relates to the field of control and communication, in particular to a method for realizing the networked architecture of a numerical control system. Background technique [0002] With the continuous improvement of the market demand of the equipment manufacturing industry, the high-end CNC system has become the guarantee for the realization of high-level digital equipment. However, in high-end CNC systems, core algorithms such as nanoscale high-precision interpolation, advanced preprocessing, multi-channel control, and multi-axis control have a huge amount of calculation, which poses great challenges to the traditional CNC system hardware and software architecture and communication platform. [0003] The traditional CNC system adopts a single-processor architecture, the core algorithm is concentrated on a single processor, the software and hardware design is intensive, and the system calculation and communication load is high. In addition...

Problems solved by technology

In addition to the support of the operating system, resources such as processors do not have a targeted allocation strategy for each controller. The system continues to be heavily loaded, making it difficult to ensure timely response to real-time tasks, leading to core algorithm data starvation. Problems such as long-time waiting for real-time tasks affect the control performance of the CNC system;
