A numerical control machine tool remote debugging system with security authentication and program tamper-proofing mechanism

Abstract

This invention discloses a remote debugging system for CNC machine tools with security authentication and program anti-tampering mechanisms, relating to the fields of industrial IoT and remote debugging technology for CNC machine tools. The system includes a remote security authentication module, a program incremental generation module, a security verification and blocking module, a program version management module, a debugging log storage module, and a delay compensation control module. This invention achieves remote monitoring, diagnosis, and debugging of CNC machine tools through the collaboration of an industrial cloud platform, intelligent gateway, and PLC control system, improving the efficiency of remote equipment operation and maintenance. By introducing two-way authentication, PLC program incremental verification, illegal remote write blocking, and program modification log tracking mechanisms, the security and traceability of the remote debugging process are effectively improved, preventing illegal program tampering. The delay compensation synchronization control algorithm corrects the time of remote control commands, improving the synchronization and stability between remote control and equipment execution.
