Abstract

Some embodiments may include a water supply system for supplying water based on a predetermined planned daily supply amount of water. While the worries supplied, it may be determined whether a second time has reached after a predetermined time passed from a first time. When it is determined that the second time has reached, an accumulated amount of the supplied water may be measured. A difference between the measured accumulated amount of the supplied water and the planned daily supply amount of water may be calculated. The planned daily supply amount of water may be corrected by adding the calculated difference to the planned daily supply amount of water after the second time. Water may be supplied based on the corrected planned daily supply amount of water.

First claim

What is claimed is:

1. A method for supplying water based on a predetermined planned daily supply amount of water, the method comprising:
measuring an accumulated amount of actually supplied water in real time with a predetermined periodicity;
acquiring record data about the accumulated amount of actually supplied water after the accumulated amount of actually supplied water is measured;
calculating a predicted daily demand amount of water based on the accumulated amount of actually supplied water according to a predetermined prediction method after the record data about the accumulated amount of actually supplied water is acquired;
setting a planned daily supply amount of water based on the predicted daily demand amount of water after the predicted daily demand amount of water is calculated;
supplying water from a water supply based on at least the planned daily supply amount of water;
determining whether a second time has been reached after a predetermined time passed from a first time while performing the supplying of the water;
measuring, when it is determined that the second time has been reached, an accumulated amount of the supplied water;
calculating a difference between the measured accumulated amount of the supplied water and the planned daily supply amount of water;
correcting the planned daily supply amount of water by adding the calculated difference to the planned daily supply amount of water; and
supplying water from the water supply based on the corrected planned daily supply amount of water,
wherein the method is performed under control of a controller, and
wherein the planned daily supply amount of water includes plan information about the amount of water to be supplied between a current time at which the planned daily supply amount of water is calculated and a midnight of a date including the current time.

2. The method according to claim 1 , wherein the correcting comprises:
determining whether the difference is greater than or equal to a predetermined amount of water; and
adding, when it is determined that the difference is greater than or equal to the predetermined amount of water, the calculated difference to the planned daily supply amount of water, and maintaining the predetermined planned daily supply amount of water when it is determined that the difference is less than the predetermined amount of water.

3. The method according to claim 1 , wherein the correcting comprises:
determining whether the planned daily supply amount of water obtained through the adding is greater than or equal to a predetermined upper water amount limit; and
changing, when it is determined that the planned daily supply amount of water obtained through the adding is greater than or equal to the predetermined upper water amount limit, the planned daily supply amount of water obtained through the adding to the upper water amount limit, and maintaining the planned daily supply amount of water obtained through the adding when it is determined that the planned daily supply amount of water obtained through the adding is less than the predetermined upper water amount limit.

4. The method according to claim 1 , wherein the correcting comprises:
determining whether the planned daily supply amount of water obtained through the adding is less than or equal to a predetermined lower water amount limit; and
changing, when it is determined that the planned daily supply amount of water obtained through the adding is less than or equal to the predetermined lower water amount limit, the planned daily supply amount of water obtained through the adding to the lower water amount limit, and maintaining the planned daily supply amount of water obtained through the adding when it is determined that the planned daily supply amount of water obtained through the adding is greater than the predetermined lower water amount limit.

5. The method according to claim 1 , further comprising:
calculating a plurality of first predicted demand amounts of water according to a plurality of combinations of applying a weight to each of a plurality of demand predictions; and
calculating the difference between the measured accumulated amount of the supplied water and each of the predicted demand amounts of water and selecting a combination for calculating a second predicted demand amount of water including a smallest difference from among the predicted demand amounts of water; and
correcting the planned daily supply amount of water after the second time according to the selected combination.
