Description

Water management block management optimization system and method {Optimal management system and method for blocked waterworks}

The present invention relates to a water supply block management optimization system and method thereof, and more specifically, to measure the flow rate and water pressure flowing into a certain block to monitor the flow rate and water pressure supplied to the consumer water supply, which is the minimum unit of water supply management. In addition, it transmits the measured data to the host computer through the wireless data transmission network, monitors and analyzes the data (flow rate and water pressure) to analyze the water supply usage pattern to identify the proper diameter of the local network and the range of proper pressure maintenance. Overflow analysis helps to identify leaks.

Generally, it is very difficult to control the flow rate and water pressure due to the web of tangled web as the tap water from the water treatment plant is distributed into a wide water supply area through several reservoirs and is supplied to the consumer.

In this way, in order to rationalize and control the water supply, water pressure management, and pipe network management due to the wider water supply facilities, the water supply zone is divided into several controlable blocks considering water systems and road networks, and the flow rate and water pressure for each block unit are divided. Block system management is a method of approaching optimized management that contributes to smooth water supply through stable water supply, and in particular, increases the flow rate through flow monitoring and pursues rationalization of management. do)

Here, the most important elements for the management in the block are the flow rate and the water pressure.

In other words, in order to reduce the waste water economically, it is necessary to monitor the whereabouts of the flow rate and to maintain the proper pressure for smooth water supply.

However, the condition is followed to monitor the whereabouts of the flow rate and to obtain the actual data of the water pressure.

As shown in FIG. 1, the sum q of the usage amount sq used separately by a plurality of consumers in the block, such as the flow rate Q flowing in a certain block, in real time at the same time (Q) and (q). The most important and important condition is to collect the amount of data and collect the water pressure (P) at the same time as the flow rate.

In particular, as described above, the method of simultaneously collecting the inflow Q in the block, the total amount q used by the customer side, and the water pressure P according to the flow rate change at the same place have been extremely difficult.

However, in order to approach in this way, the flow rate in the block is analyzed by analyzing the flow rate and the water pressure by installing a zone flowmeter and installing a self-locking water pressure meter at any point. However, the problem is that in the measurement of flow rate, there is no data for judging the amount of inflow and the amount of usage at the same time. Alternatively, there is a method of proactively locking the meter on the consumer side and checking the inflow (Q).

However, the method of using the meter reading for the electronic water bill notification is not a simultaneous data of inflow and usage, so there are too many inaccurate factors in the analysis according to the change of water supply. Because there is a possibility of complaints, there is no limit in achieving accuracy by collecting and analyzing the current condition of flow monitoring and hydraulic pressure fluctuation every day. Currently, the current situation is used to grasp the actual situation using the former method.

Accordingly, an object of the present invention is to divide a wide range of water supply zones in block units and analyze and receive data at a certain period, i.e., at least a time unit, at the same time through a real-time wireless remote measurement means for a unit area inflow, individual use amount, and water pressure. The present invention provides a water supply block management optimization system and method for estimating water leakage in the block by estimating the amount of leakage in the block based on accurate analysis data and continuously performing precision leak detection. .

Another object of the present invention can be analyzed by the time unit by selecting the flow rate and pressure analysis for each block unit area by month or day, and the analysis results can be easily confirmed by displaying the analyzed flow rate and pressure content in a graph (Graph) The present invention provides a water supply block management optimization system and method thereof.
