Cross-platform numerical control system

Abstract

The invention relates to a cross-platform numerical control system, which is technically characterized in that a display screen, a MDI (Multiple Document Interface) keyboard box, a machine tool operation panel box, a soft key box and a hand wheel box are all mounted on a control panel of a case of the cross-platform numerical control system; a control circuit in the case comprises a PCI (Peripheral Component Interconnect) numerical control operation element state scanning main board, an industrial control main board and a motion control card, which are orderly connected in a RS232 mode; the PCI numerical control operation element state scanning main board is connected with the MDI keyboard box, the machine tool operation panel box, the hand wheel box and the soft key box through a serial port, the industrial control main board is connected with the display screen via a VGA (Video Graphics Array) port, and the motion control card is connected with a numerical control machine tool main body through a driver interface and a coder interface. According to the invention, different types of numerical control systems can be reconstructed quickly by replacing the MDI keyboard box, the machine tool operation panel box and the soft key box and changing the function mappings, so that the cross-platform numerical control system has wide market and application prospect in the fields of numerical control system development, function demonstration, simulation, vocational skill training and the like.

Description

technical field [0001] The invention belongs to the technical field of numerical control, in particular to a cross-platform numerical control system. Background technique [0002] With the rapid development of the manufacturing industry, the proportion of CNC equipment in the manufacturing industry is increasing. As the key control components of CNC equipment, the CNC system has different structural forms, which can be roughly divided into traditional CNC systems, open CNC systems with "PC embedded in NC" structure, open CNC systems with "NC embedded in PC" structure, pure software type There are five types such as open CNC system and network CNC system. Expandable, reconfigurable, and modular open CNC systems are the mainstream direction of CNC technology development. The existing open CNC systems have the following problems: [0003] 1. In order to protect their existing monopoly market position, old foreign CNC system manufacturers occupying high-end CNC systems, such a...

AI Technical Summary

Problems solved by technology

This structure does not realize openness in the true sense, and it is almost impossible to expand and reconfigure this type of system

[0004] 2. Domestic CNC system manufacturers generally adopt the open mode of "NC embedded in PC", but their development idea is to take the road of independent CNC brand, that is, to define their own command set, parameter area format and operation mode, and the core CNC software is different from each other. compatible

This structure has a certain degree of openness, but it cannot yet achieve compatibility and rapid reconfiguration of different types of CNC systems

[0005] 3. Due to the large number of CNC system manufacturers at home and abroad, the CNC system lacks sufficient flexibility, and the instruction format and operation mode are different, which has caused great resource duplication and waste in many aspects.

Taking the field of CNC vocational skills training and CNC maintenance training as an example, if a school wants to train different CNC systems, it needs to purchase machine tool equipment of different CNC systems. These equipment are expensive, require huge investment, and resource duplication and waste are serious. Meet the target requirements of green remanufacturing
