Description

How to control image animation in graphical user interface controls of machine tool monitor

The present invention relates to graphic-based UI control on a machine tool monitor screen, and more particularly, to a method for displaying the movement of a pallet table of a machine tool on a monitor screen as an image animation.

In general, a touch panel-type HMI (Human Machine Interface) device is used to monitor the work process and input necessary parameters in numerical control machine tools.

This HMI device is a graphical user interface (GUI) without any additional programming, so that the HMI screen can be configured by performing only basic operations using a keyboard and mouse.

According to Patent Document 1 as a prior art, the HMI device includes an HMI configurator capable of configuring an HMI screen by performing basic graphic-based operations using an input device.

This HMI configurator preferably includes an HMI simulator, a component property extractor and a component property editor.

The HMI simulator loads the necessary data from the HMI description data that stores the HMI screen configuration information, and drives the HMI in the same way as the HMI mounted on the computer numerical control (CNC).

The component property extractor extracts property information, which is the basic unit that can be modified from the component, which is an HMI screen component.

It allows you to edit component properties based on the information extracted from the component property extractor in the component property editor.

Since the HMI configurator includes the HMI simulator, the information configured in the component property editor is immediately updated on the screen, and the contents of the HMI screen can be grasped in real time, making it easy to configure the HMI screen.

All of the HMI screen configuration information modified or newly configured through this HMI configurator can be expressed as HMI descriptive data.

The HMI part uses the newly configured HMI description data to drive the same screen as in the HMI configurator to the numerical control device.

To this end, the HMI unit includes an HMI description data parsing unit, a component creation unit, and a component management unit.

The HMI description data parsing unit reads the HMI description data to analyze the HMI configuration and find out the necessary screen configuration.

The component creation unit creates components belonging to the HMI screen based on the information received from the HMI description data parsing unit.

The component management unit manages the numerical control device to operate as configured in the HMI configurator.

The HMI Configurator scans the component list from the HMI description data and reads and analyzes the HMI configuration. They are used to form HMI systems, screen structures, pages, and components. Add a new component, edit an existing component, or delete an existing component using the formed HMI system, screen structure, page, and components. It determines whether the add, edit, or delete steps have been completed, and if it is determined that it is complete, creates an HMI configuration, and updates the HMI description data by packaging the HMI configuration and components.

In order to express the state and movement of the machine tool palette as an animation on the machine tool monitor screen using such an HMI device, the image animation function on the monitor screen can be set through a touch panel program or PLC.
