Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a database that stores information on a water supply facility diagram including a water source, a water pipe, and a valve that supplies water from the water source to the water pipe, Search means for searching for the latest specific valve connected to the specified specific water pipe on the water supply facility map from the information, and the area surrounded by the specific valve is determined as a specific area different from other areas. The present invention relates to a pipe network management device including a processing device including an output area determination unit.

[Prior Art] Conventionally, in this type of pipe network management device, prior to laying a distribution pipe or a water supply pipe in a water supply facility, the pipe network management device searches for an area to be cut off due to construction or the like. , The construction personnel were able to accurately identify the water-off area, take appropriate measures, and contact the users of the facility in advance to extract information for smooth work execution.

[Problems to be Solved by the Invention]

However, according to the pipe network management device according to the above-mentioned conventional technique, the specific distribution pipe specified by the search means on the water supply facility diagram, that is, the nearest specific valve connected to the distribution pipe as the construction target is determined from the information. When searched, the area discriminating means discriminates and outputs only the area surrounded by the specific valve as a specific area different from other areas, that is, the water shutoff area. When the non-supplied region occurs in a region other than the specific region, the region is treated as if it is a water-uninterrupted region, and the hydraulic analysis after the water-stop by the pipe network management device, that is, after the removal of the specific region There is a possibility that the hydraulic analysis of (1) becomes impossible due to the existence of the discontinuous area, or the user is not notified of the interruption of the water.

An object of the present invention is to eliminate the above-mentioned conventional disadvantages.

[Means for solving the problem]

In order to achieve this object, the characteristic configuration of the present invention is configured such that, in the area discriminating means, whether or not a water pipe in an area different from the specific area connected to the specific valve is connected to the water source is determined from the information. It is because there is provided a water source connection discriminating means for discriminating by search and outputting, when the region is not connected, it is discriminated and outputted as belonging to the specific region.

Further, it is preferable that the water source connection determination means act only on the water distribution pipe in a region on the downstream side in the flow direction with respect to the specific water distribution pipe.

[Action]

In other words, the region determination means not only determines the region surrounded by the specific valve as the water cutoff region, but also closes the specific valve so that the region other than the region surrounded by the specific valve is connected to the specific valve. Since the area where the water distribution pipe is not connected to the water source is also cut off, the area is also discriminated and output as a water cut area, that is, a specific area.

Furthermore, regarding the flow direction in the specific water pipe with the specific valve opened, we recognize that there is always a water source in the upstream area, and we will check whether the water source is connected only in the downstream area. By searching, it is possible to determine in a short search time.

〔The invention's effect〕

Therefore, according to the pipe network management apparatus of the present invention, it is possible to perform the preliminary confirmation of the water cutoff area and the hydraulic analysis after the water cutoff extremely accurately, so that the work related to the construction can be performed extremely smoothly. It was
