双机热备技术在井下人员定位系统中的研究与应用

摘要

井下人员定位系统在事故发生后能及时统计井下人员的数量和所在位置，节约了大量的救援时间和救援资金，在历次事故救援工作中起到了举足轻重的作用。但是人员定位系统主机服务器由于需要长期24h不间断运行，时常出现死机等问题，如果没有及时发现并人工重启主机，就会造成人员下井数据的缺失，导致下井人员轨迹图的混乱，高煤公司采用了双机热备技术后很好地解决了这个问题。%The underground personnel positioning system can timely statistics the number and location of underground personnel after the accident, saving a lot of time for rescue and relief funds, ,which has played an important role in the previous accident rescue work. But the host server of the personnel positioning system is running for 24 hours and no interruption, which often crashes and other problems, if not promptly found and restart the host, it will cause the lack of well data personnel, resulting in the trajectory confusion of underground personnel, GaoZhuang coal company uses double machine hot standby technology to well solve this the problem.
