Abstract

The present invention relates to the field of encryption control, in particular to a hardware encryption device based on a PROFIBUS bus. The hardware encryption device includes a numerical control unit, an encryption unit and a PROFIBUS bus, and the PROFIBUS bus is respectively connected to the numerical control unit and the encryption unit; wherein, the The numerical control unit sends an operation request to the encryption unit through the PROFIBUS bus, and the encryption unit feeds back encryption state information to the numerical control unit through the PROFIBUS bus according to the operation request. The hardware encryption device implements hardware encryption based on the PROFIBUS bus, which has a high degree of encryption and is difficult to be cracked by violence.

Description

technical field [0001] The invention relates to the field of encryption control, in particular to a hardware encryption device based on a PROFIBUS bus. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency automatic machine tool that represents the development ...
