【摘要】：时间同步是煤矿井下监控系统重要的基础组件技术,有效地保证了井下人员的安全。传统时间同步算法同步误差随跳距积累且容错性较差,不适合应用于煤矿井下。基于国内外研究现状,结合实际环境,在传统时间同步算法的基础上提出了簇状结构的低功耗时间同步算法和容错性时间同步算法。通过搭建时间同步测试平台,从算法精度、正确性、健壮性3方面对低功耗时间同步算法进行验证。研究表明:簇状结构的低功耗时间同步算法比传统算法的稳定性更强。
[Abstract]:Time synchronization is an important basic component technology of underground monitoring system in coal mine, which effectively ensures the safety of underground personnel. The synchronization error of the traditional time synchronization algorithm accumulates with the hopping distance and the fault tolerance is poor, so it is not suitable to be used in the coal mine. Based on the current research situation at home and abroad, combined with the actual environment, a cluster structure low power time synchronization algorithm and a fault-tolerant time synchronization algorithm are proposed based on the traditional time synchronization algorithm. By setting up a time synchronization test platform, the low power time synchronization algorithm is verified from three aspects: accuracy, correctness and robustness. The results show that the low power time synchronization algorithm with cluster structure is more stable than the traditional algorithm.
