How to select repair section of water supply network

The present invention relates to a method for selecting a repair section of a water supply network, and more specifically, by dividing the water supply network into blocks, and providing a repair cost for a unit block estimated to be a repair target, thereby providing a budget, flow rate, and aging of a pipeline. The present invention relates to a method for selecting a repair section of a constant pipe network, which makes it easy to select a unit block to be repaired according to accuracy, hydraulic pressure in a pipe, and the like.

In the past, water supply was a supply-oriented policy, focusing on research on how to provide abundant water supply to citizens, while current water supply is established by the qualitative policy of supplying citizens without loss of clean water. And research is ongoing.

As a result, T / M (Telemetering, Telemetry, Remote Metering, Pipe Network Monitoring) is being researched as a method of supplying water to citizens with optimal quantity, water pressure and water quality and managing it. Has been created, and research is being conducted to try T / M by various methods.

In general, tap water used at home is supplied to each household (water consumer) from a water source to a water purification plant and a drainage basin. At this time, proper water quality management or maintenance and management of the network is very difficult through the web network tangled like a spider web from the water purification plant to the consumer.

Accordingly, in order to optimize the management of the water supply network and to increase the flow rate, which is the rate of collecting water from the tap water produced by the water purification plant, a project is being made to block the water supply network.

For example, the water pipe blocking project divides the large blocks divided by the water supply system of the water purification plant into heavy blocks of 2000 to 5000 water supply scales, and divides each heavy block into small blocks of 500 to 1000 water supply scales. It consists of large, medium and small blocks in the shape of a checkerboard. It has the advantage of maintaining and managing more systematic and efficient network through real-time monitoring and analysis of quantity, water quality and water pressure by block.

The terms used in the present invention were selected as general terms as widely used as possible, but in some cases, the terms arbitrarily selected by the applicant are included. In this case, the meanings described or used in the detailed description of the present invention are considered, rather than simply the names of the terms. The meaning should be grasped.

Hereinafter, with reference to the preferred embodiments shown in the accompanying drawings will be described in detail the technical configuration of the present invention.

However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Like numbers refer to like elements throughout the specification.

In addition, the manager interface may be implemented such that the flow direction, the flow rate of the water supply pipe can be expressed, and the water supply pipe of the unit block estimated to be repaired and the water supply pipe of the unit block not estimated to be repaired can be represented to be partitioned from each other. have.

This has the advantage of increasing convenience in policy making to select the compensation target.

For example, the water supply line of the estimated unit block and the water supply line of the unit block not estimated to be repaired may be represented in different colors. However, it is not limited thereto.

Next, a step of selecting a repair target unit block using the manager interface is performed (S500).

In this case, the repair target unit block may be determined by reflecting the information on the budget, the flow rate, the degree of aging of the pipeline, the pressure in the pipe.

Next, the step of providing information about the selected repair target unit block to the builder interface applied to augmented reality is performed (S600).
