    • In a method of estimating a fracture point of a pipe line network, a group of estimating rules based on distribution characteristics of extraordinary pressure variation, pipe line characteristics and flow continuity requirements in a fracture accident monitoring system for such networks represented by a large scale water distribution pipe line network are applied to reference data of flow rates and pressures both obtained in the normal consumption condition, and to measured data of the flow rate and the pressure to estimate the fracture point. In the method, application order of individual ones of the group of the estimating rules is decided in accordance with data conditions of the pipe line network. In the case that a range of a set of suspected abnormal joints can not be reduced sufficiently to the extent of a practical tolerance limit, a numerical simulation which supposes the existence of fracture on a certain joint in the set of suspected abnormal joints is conducted to further reduce the range of the set of suspected abnormal joints through a comparison between results of the numerical simulation and measured results. In order to increase an estimating speed, a parallel processing is conducted for the estimating rules which utilize only local data in the pipe line network, by way of a plurality of the special purpose reasoning processors.
    • 在一种估计管网网络断裂点的方法中,基于大型水面代表的网络断裂事故监测系统中基于非常压力变化分布特征,管线特性和流量连续性要求的一组估计规则 分配管线网络应用于在正常消耗状态下获得的流量和压力的参考数据,以及流量和压力的测量数据以估计断裂点。 在该方法中,根据管线网络的数据条件来决定该组估计规则中的各个应用顺序。 在一组可疑异常关节的范围不能足够减小到实际容许限度的程度的情况下,进行假设在可疑异常关节的集合中的某个关节上存在断裂的数值模拟 通过比较数值模拟和测量结果的结果,进一步减少了一组疑似异常关节的范围。 为了提高估计速度,通过多个专用推理处理器对管线网络中仅使用本地数据的估计规则进行并行处理。
