Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to an encryption system based on digital information transmission. Background technique [0002] CNC machine tool is the abbreviation of Computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system can logically process the program with control code or other instruction data, decode it, express it with coded numbers, and input it into the numerical control device through the information carrier. After arithmetic processing, various control signals are sent by the numerical control device to control the action of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] With the development of information technology and the rise of industrial costs, remote control of CNC machine tools is not only more convenient, but also effectivel...

Problems solved by technology

However, since CNC machine tools are high-end manufacturing tools, errors in operating instructions will lead to irreparable losses. Therefore, data encryption control is required during remote control, not only to prevent data distortion during transmission, but also to avoid network intrusion by hackers

[0004] However, when the encryption control is performed during the instant transmission of the command data of the CNC machine tool, due to the difference in the precision requirements of different command data during CNC, the data encryption is affected by the highest precision data, that is, the data encryption operation is required by the highest precision standard, resulting in the accuracy Instruction data with low requirements will have some invalid encrypted data, which wastes the amount of encrypted computing data, resulting in slow encrypted computing and difficult to complete encrypted control in time, resulting in slow response during remote control of CNC machine tools and delays in processing progress
