基于簇状结构的时间同步算法

摘要

Time synchronization is an important component technology in coal mine monitoring system, which can effectively ensure the personnel safety.The traditional time synchronization algorithm was not suitable for the coal mine, due to the synchronization error accumulation with hop distance and poor fault tolerance,not suitable for application in the coal mine.Based on the research status at home and abroad, combining with the actual environment, the low power consumption time synchronization algorithm and fault tolerance time synchronization algorithm with cluster structure were proposed based on the traditional time synchronization algorithm.By setting up the time synchronization test platform, the algorithm was validated from three aspects of algorithm accuracy, correctness and robustness.The research shows that the low power consumption time synchronization algorithm of cluster structure is more stable than the traditional algorithm.%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.
