Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water pipe management system, and more particularly to a system for centrally managing the presence or absence of water leakage in a water pipe network in a management target area.

[0002]

2. Description of the Related Art In general, the maintenance and management of a water pipe network laid by a local government or the like in its jurisdiction area is carried out regularly by conducting a water leak test. Conventionally, the sound hearing method has been generally used. In this method, a worker listens to the sound generated from a water pipe buried in the ground using a rod-shaped sound hearing device during a time period when noise is relatively low, such as at midnight, but the water pipe is used. Performing this inspection on the entire net requires a great deal of time, and requires a high level of skill because it is necessary to distinguish between water leaks and other noises. For this reason, this water leak inspection has conventionally been a very expensive and inefficient operation.

To cope with such a situation, Japanese Patent Laid-Open No.
Japanese Patent Publication No. 196798 proposes a method for automatically detecting the presence or absence of water leakage.

In this method, the sound of a water pipe is periodically measured at a specific time zone at midnight, for example, at intervals of three minutes, by a detector using a sound sensor installed on the water pipe, and the periodic inspection is performed. If no sound is detected during this period, it is determined that there is no water leakage, and if sound is detected for all of the periodic inspections, it is determined that there is water leakage.

[0005] Then, the result is visually displayed on the detector, and the inspector visually checks the display later to confirm the presence or absence of water leakage. And wirelessly receive the detection result to confirm the presence or absence of water leakage. According to this, the inspection relying on the ears of the skilled worker is improved, and the water leakage inspection is streamlined.

[0006]

However, the method disclosed in the above-mentioned publication merely checks the presence or absence of water leakage at each measurement point individually, and is only provided in a jurisdiction area. How to efficiently conduct water leakage inspection and the processing and use of the inspection results for the entire water pipe network,
Such a problem cannot be solved.

[0007] Therefore, the present invention provides a system capable of centrally managing the presence or absence of water leakage in a water pipe network in a management target area, and efficiently performing a water leakage inspection and processing and use of the inspection result. As an issue.
