Remote on-line monitoring method for numerical control equipment

Abstract

The invention discloses a remote on-line monitoring method for numerical control equipment, and belongs to the field of numerical control equipment. The method comprises the following steps of: (1) acquiring initial position information of each moving element of the numerical control equipment; (2) acquiring current position information of each moving element of the numerical control equipment; (3) performing data exchange on the current position information to acquire a position variable value of each moving element model in OpenGL; (4) establishing an OpenGL model of the numerical control equipment according to the position variable value and the initial position information, and performing real-time on-line monitoring on the numerical control equipment through the OpenGL model; (5) when the acquired position variable value is in a first moving interval of the corresponding moving element in the OpenGL model, judging the position as an effective moving position, otherwise, controlling the numerical control equipment to stop working; and (6) judging whether the control process of the numerical control equipment is finished, if so, finishing the flow, otherwise, re-executing the step (2).

Description

technical field [0001] The invention relates to the field of numerical control equipment, in particular to a remote on-line monitoring method for numerical control equipment in the fields of numerical control machine tools, robots and servo control systems. Background technique [0002] In various CNC processing equipment, it is often equipped with a high-precision pulse encoder, or a precision positioning device such as a grating ruler, to improve the control accuracy of the CNC processing equipment and realize closed-loop or semi-closed-loop digital control; industrial robots are due to Due to the complexity of the motion process, the semi-closed-loop motion control is usually only realized through the pulse encoder of the servo motor itself. In the actual working process of CNC equipment movement, designers and developers often monitor the CNC equipment in real time through feedback signals such as grating rulers. When the CNC equipment runs beyond the theoretical limit p...

Problems solved by technology

This method is relatively simple, and can also help users make reasonable judgments and accurate control of the operating status of CNC equipment. However, this design process can only be monitored online within a limited range of viewports, and cannot be viewed from the overall perspective. Or to achieve a more perfect online monitoring in terms of details, when the user wants to observe the working status of the machine tool from the back and side, it seems powerless
