Modularized reconfigurable networked digital control system in open type

Abstract

The invention relates to a reconstructable network open digital control system that includes bus connecting main controlling module, memory extending module, motion control module, network module, human-computer interface module, PLC module, and state monitoring module. Each module includes a function circuit, bus interface and module identification chip and a hardware driving and process reflection chip. The main control module contains open type embedded real time operation system that is running virtual module. The module identification chip stores the identification code of the seven modules to describe the function type. The invention is suitable for MCU, and DSP core digital system.

Description

technical field [0001] The invention belongs to the numerical control adjustment technology, in particular to a computer modularized and reconfigurable networked open numerical control system. Background technique [0002] At present, the numerical control system can be divided into two structural systems, that is, the numerical control system based on PC architecture and the closed numerical control system with single-chip microcomputer as the control core. [0003] The CNC system based on the PC architecture inherits the modularization and openness of the PC, and the hardware platform of the CNC system can be constructed as long as it is configured with a general-purpose industrial control host, motion control card, human-computer interaction panel, and network interface. At the same time, with the general operating system and general software development environment, it is easy to quickly establish the software platform of the numerical control system.

Problems solved by technology

However, the CNC systems based on single-chip microcomputers generally have the disadvantages of poor openness and non-modular design.

Its closed hardware architecture makes the CNC system a device with fixed functions, so it is difficult to realize the reconfigurability of the system, which limits the flexibility of the end user, and it is difficult to achieve the control of various processing machines, processing modes and automatic processing networks. Universal adaptation; its software system is usually a fixed program customized according to a specific CNC system, which is not open to users and has no unified interface, which limits the reconfigurability of the software and limits the software functions of such systems. it is difficult to change
