煤矿机械

煤矿综采工作面环境复杂，突发事故易导致通信电缆损坏，进而影响井下有线通信系统的正常运行。为提高通信系统的抗故障能力和运行可靠性，研究了不同通信链路间的数据切换技术，并构建了一种基于有线-无线融合的多链路冗余通信系统。该系统利用WiFi 6基站实现工作面的无线信号覆盖，同时结合有线链路检测协议和无线链路冗余传输协议，仅通过一次跳转即可绕过故障链路，避免传统无线中继系统的多跳传输延迟问题，从而实现高效的多链路冗余通信。实验结果表明，该系统能有效提升综采工作面通信网络的传输效率和抗灾变能力，为煤矿应急通信提供可靠的技术支撑。

The fully mechanized coal mining face operates in a complex environment, where sudden accidents can easily damage communication cables, thereby affecting the normal operation of the underground wired communication system. To enhance the fault tolerance and operational reliability of the communication system, studied data switching technologies among different links and built a multilink redundant communication system based on wired-wireless integration. This system utilizes WiFi 6base stations to achieve wireless signal coverage in the working face while incorporating wired link detection and wireless link redundancy transmission protocols. By bypassing faulty links with a single hop, it effectively avoids the multi-hop transmission delays inherent in traditional wireless relay systems, thereby enabling efficient multi-link redundant communication. Experimental results demonstrate that this system can significantly improve transmission efficiency and disaster resilience in the fully mechanized mining face, providing reliable technological support for emergency communication in coal mine.
