Abstract: To address issues such as data communication delays and low levels of automation and intelligence in existing monitoring and control systems of mine substations, this study designed an automated monitoring system based on the key requirements of mine substation operations. The system design included both the overall structure and an analysis of its core monitoring logic and functions. By integrating measurement and control devices into a clustered management structure, the new system centralized the previously dispersed monitoring functions across different switchgear bays.Application tests showed that the optimized system improved data communication efficiency by 88.3% and reduced the substation's operational failure rate by 87.5%, significantly enhancing monitoring performance. This design provides a valuable reference for the optimization of monitoring systems in mine substations under similar working conditions.
