摘要
煤矿井下突发安全事故后,科学判断出救助点周围人员的分布是制定救援方案的关键。本文将反向最近邻的查询算法加以改进,用于查询救助点周围井下人员的分布情况,为实施最有效的救援提供依据。实验表明该算法适用于井下无线传感器网络中的移动对象的反向最近邻查询。
When a security accident happened to the coal mine, it is crucial to estimate the distribution of staff around the rescue workers. Reverse nearest neighbor query algorithm is improved for the inquiry the distribution of person trapped in coal mine around the rescue workers, and provided the most effective basis for rescue. Experiments show that the algorithm is suitable for the query of reverse nearest neighbor to moving objects in wireless sensor network of coal mine.
