A Screen Locking System Applied to Numerical Control Machine Tool

Abstract

The invention discloses a screen locking key system for a numerical-control machine tool. The screen locking key system comprises a screen display module, a screen signal acquisition module, a locking module, a password authentication module and an unlocking module. The screen display module is used for displaying state information of the locking key system on a screen, the screen signal acquisition module is used for acquiring a trigger signal of the screen operated by a user, judging content of the signal and responds corresponding to the content of the signal, the locking module receives a locking request of the screen signal acquisition module and enables the screen to enter a locked state, the password authentication module receives an unlocking request of the screen signal acquisition module and enters a password authentication state, and the unlocking module receives an unlocking request of the password authentication module and releases the screen from the locked state. The screen locking key system is applied to the numerical-control machine tool, misoperation to the touch screen of the machine tool can be prevented, and production safety is improved.

Description

technical field [0001] The invention relates to a screen key lock system, in particular to a screen key lock system applied to a numerically controlled machine tool. Background technique [0002] At present, CNC machine tools using touch control screens have been widely used in the production and processing of products. CNC machine tools with touch control screens are easier to operate than traditional button-type CNC machine tools, but they also have shortcomings. They cannot be listed on their own to prevent misuse like button-type machine tools. The current CNC machine tools using touch control screens also lack other necessary measures to prevent misuse, which is a relatively large safety risk for CNC machine tools whether they are in the processing state or in the power-on inspection state. Contents of the invention [0003] The object of the present invention is to provide a screen key lock system applied to a numerical control machine tool. [0004] The technical ...
