AI Technical Summary
Existing underground communication technologies struggle to balance real-time performance and robustness, limiting the improvement of automation levels in fully mechanized coal mining faces. This is especially true in scenarios involving long-distance transmission or high-density equipment access, where signal attenuation and interference are severe, impacting the accuracy and efficiency of collaborative equipment operations.
A robust and real-time downhole multi-device data communication system is constructed using industrial Ethernet switches, wireless base stations, a network management platform, and a master clock server. By combining time-sensitive networking protocols and wireless network protocols with network performance monitoring and dynamic scheduling strategies, data transmission paths and bandwidth allocation are optimized.
It enables efficient and reliable transmission of communication for underground equipment in coal mines, ensures timely transmission of critical task data, improves system stability and overall communication efficiency, and supports the safe, reliable, and automated operation of fully mechanized mining faces.
