A multi-network fusion intelligent communication system and method suitable for complex environments of mine tunnels

Abstract

This invention relates to the field of underground mine communication technology, and more particularly to a multi-network converged intelligent communication system and method suitable for the complex environment of mine roadways. The system integrates 5G private network communication links, industrial Ethernet communication links, WiFi 6 communication links, 4G private network communication links, and Mesh self-organizing network communication links through a multi-standard communication link integration module, constructing a heterogeneous network resource pool. An intelligent router integrates a link status monitoring unit, a link quality assessment unit, and an intelligent link selection and aggregation unit, performing real-time quality assessment of each link through a weighted scoring algorithm and dynamically deciding whether to adopt the optimal single path or multi-path aggregation transmission mode. A breakpoint resumption module is equipped with an independent power supply and local storage unit, enabling local data caching during network interruptions and automatic resumption of transmission after link recovery, ensuring the continuity and integrity of data transmission. This invention solves the technical problems of unstable, easily interrupted, and high packet loss rates in complex underground mine environments. In field tests at a -470-meter horizontal connecting roadway, the average data transmission packet loss rate was controlled below 8%, significantly improving the data transmission reliability and environmental adaptability of the mine roadway monitoring system.
