Remote-control based numerically-controlled machine tool safety system allowing direct unlocking

Abstract

The invention discloses a remote-control based numerically-controlled machine tool safety system allowing direct unlocking, belonging to the technical field of numerically-controlled machine tools. The remote-control based numerically-controlled machine tool safety system comprises a single-chip microcomputer, a touch screen locking key and a remote control terminal. The touch screen locking key and the remote control terminal are connected in a wireless manner. The touch screen locking key comprises a screen display module, a signal display module, a locking module, a password access request module, a password input module, a password authentication module and an unlocking module. The password access request module and the password authentication module are both wirelessly connected with the remote control terminal. The remote control terminal comprises a processing unit, an operation APP, a password generation module, a recording module, a conversation module and a password output module. A password is generated by the remote control terminal, and is directly sent to the password authentication module by the password output module for the purpose of unlocking. The invention allows unlocking by inputting the preset password or directly by the remote control terminal.

Description

technical field [0001] The invention relates to a security system of a numerical control machine tool, in particular to a security system of a numerical control machine tool which can be directly unlocked based on remote control, and belongs to the technical field of numerical control machine tools. Background technique [0002] Machine tool (English name: machine tool) refers to a machine that manufactures a machine, also known as a machine tool or a machine tool. It is customarily referred to as a machine tool. It is generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. The method of processing mechanical parts in modern machinery manufacturing Many: In addition to cutting processing, there are also casting, forging, welding, stamping, extrusion, etc., but all parts with high precision requirements and fine surface roughness requirements generally need to be final processed by cutting methods on machine tools , Machine to...

Problems solved by technology

[0004] At present, CNC machine tools using touch control screens have been widely used in the production and processing of products. CNC machine tools using touch control screens are easier to operate than traditional button-type CNC machine tools, but there are also shortcomings, and they cannot stand on their own like button-type machine tools. Listing prevents misoperation. The current CNC machine tools using touch control screens also lack other necessary measures to prevent misoperation. This is a relatively large safety risk for CNC machine tools whether they are in the processing state or in the power-on inspection state, especially When large-scale precision CNC machine tools are in use, they must be used, inspected, or even cared for by special personnel. In this case, in order to prevent unfavorable consequences caused by misoperation by others, many companies set passwords for CNC machine tools. At present, , the set password is the only password. Before changing the password, you can turn on the machine at any time after obtaining the password once. This cannot effectively prevent more people from knowing the password and starting the CNC machine tool to cause misoperation. Therefore, you can directly The direct unlocking operation through the remote control terminal is the focus of current research
