The invention discloses a network security protection method, a device and a system for a numerical control system. The network security protection method for the numerical control system comprises the steps that a network protection terminal receives preset data from a preset network, wherein the network protection terminal only receives data in a text format, the preset network is used for transmitting production data of numerical control equipment, the production data of the numerical control equipment is data of the numerical control equipment for processing production, and the preset data is the data in the text format; and the network protection terminal transmits the preset data to the numerical control equipment. According to the method, the device and the system, the problem of poorer protection performance of the numerical control system during network security protection is solved; and the processing production is accomplished by transmitting the production data of the numerical control equipment to the numerical control equipment via the network protection terminal, so that an effect of improving the protection performance of the numerical control system during the network security protection is achieved.
Description
technical field [0001] The present invention relates to the field of numerical control, in particular to a network security protection method, device and system for a numerical control system. Background technique [0002] At present, with the continuous progress of numerical control technology, more and more functions can be realized by numerical control equipment, and the performance is getting better and better. In order to further improve production efficiency, it is more and more popular to form a distributed numerical control (DNC for short) system by networking numerical control equipment. Due to differences in regional development and procurement years in my country, a manufacturing enterprise may have different CNC manufacturers and different types of CNC equipment at the same time. [0003] Most of the traditional CNC equipment adopts serial communication interface. However, due to the differences in the implementation of standard serial communication interfaces i...
