A remote monitoring and debugging method of numerical control system based on virtualization technology

Abstract

The invention discloses a numerical control system remote monitoring and debugging method based on a virtualization technology. The numerical control system remote monitoring and debugging method based on the virtualization technology comprises a virtual upper computer on a remote server, a local lower computer and a remote monitor terminal, wherein a remote monitoring and debugging module, a secure login authentication module and an intelligent diagnosis module are integrated on the virtual upper computer, the secure login authentication module is used in secure login authentication of the virtual upper computer, the remote monitoring and debugging module is used to display status data fed back to the virtual upper computer from the local lower computer through the remote monitor terminal after being verified, and simultaneously inputs the status data to the intelligent diagnosis module so as to perform fault early warning and / or health diagnosis on a machine tool, and a fault early warning or diagnosis result can be displayed on the corresponding monitor terminal. The numerical control system remote monitoring and debugging method based on the virtualization technology achieves remote monitoring and debugging for a numerical control system based on virtualization, improves intelligent level and reliability of numerical control machining, and reduces maintenance cost of a plant.

Description

technical field [0001] The invention belongs to the technical field of numerical control systems, and in particular relates to a remote monitoring and debugging method of a numerical control system. Background technique [0002] CNC machine tools can well solve complex, precise, batch-level, and multi-variety parts processing problems. They have the advantages of high precision, high efficiency, and convenient operation, and have been widely used in modern enterprises. At present, the software and hardware systems of mainstream high-end CNC systems at home and abroad are mostly upper and lower computer structures: the upper computer and the lower computer are installed next to the CNC machine tool, the upper computer is responsible for the non-real-time tasks of the system, and the lower computer is responsible for the real-time motion control and Logic control tasks, the two exchange information through the internal bus or network. Under the above CNC system architecture, ...

Problems solved by technology

[0006] However, at present, the remote monitoring and debugging module of the CNC system is directly integrated in the local CNC equipment, which not only increases the burden and cost of the local hardware of the CNC system, but also limits the development and upgrading of the monitoring and debugging module to local software and hardware resources. It will even force local software and hardware equipment to be upgraded, which will bring greater cost upward pressure to the enterprise

The remote monitoring of the traditional CNC system is generally based on the field bus. Although it has the meaning of remote operation, it is still limited by the transmission distance, and the monitoring equipment is limited to the PC.

The CNC machine tools in a workshop may use different CNC systems, so each type of CNC system needs to be equipped with a PC terminal to adapt to the communication, processing, and data processing of a specific CNC system, which is not conducive to the management and maintenance of the workshop

In addition, the current CNC system generally uses disk backup, which is very inconvenient to operate, and the disk is easily damaged. Once a misoperation occurs during remote debugging, the upper computer system falls into an irreversible failure, which will cause the entire CNC system to fail to recover normally. Moreover, in the traditional CNC system backup, the CNC machining data cannot be backed up in real time, which can easily cause data loss

In addition, in the current remote debugging of the CNC system, the maintenance center can easily control the machine tool in the workshop and obtain the processing information of the machine tool, which is not conducive to the protection of the workshop processing data by the manufacturer
