摘要
为解决煤矿铁路塌陷区因路基沉降导致电缆(光缆)损坏、半自动闭塞信号传输中断的问题,采用LORA模块自建无线局域网代替电缆(光缆)传输半自动闭塞信号,遵循相关设计原则进行安全性设计。实际应用结果显示,该方案可有效避免路基塌陷对信号传输的影响,设备安装调试时间从近20天缩短至半天,维护便捷,故障检测迅速,在某煤炭矿区试运行近一年半运行稳定。研究表明,此方法为煤矿塌陷区信号传输提供了新思路,具有降本增效的优势,应用前景广阔,但大规模应用仍需经受复杂环境考验。
To address the issues of cable(optical cable)damage and interruption of semi-automatic block signal transmission caused by subgrade settlement in coal mine railway subsidence areas,this paper proposes the use of a self-built wireless local area network based on LORA modules to replace cable(optical cable)transmission for semi-automatic block signals,with safety designs conducted in accordance with relevant design principles.Practical application results demonstrate that this solution can effectively eliminate the impact of subgrade subsidence on signal transmission.The installation and commissioning time of the equipment has been significantly reduced from nearly 20 days to half a day,with convenient maintenance and rapid fault detection.The system has operated stably for nearly one and a half years during trial runs in a certain coal mining area.The research indicates that this method provides a novel approach for signal transmission in coal mine subsidence areas,offering advantages in cost reduction and efficiency enhancement,and exhibits broad application prospects.However,large-scale deployment still needs to withstand the test of complex environments.
