Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply and distribution facility device for supplying and distributing water resources in a building, for example.

[0002]

2. Description of the Related Art FIG. 22 is a piping system diagram showing a configuration of a conventional water supply and distribution facility device for supplying and distributing water resources to each floor in a building. In the figure, 1 is a main water pipe, 2 is a water meter for measuring the amount of water supply of water resources in a building, 3 is a water receiving tank, 4 is a chlorine injector, 5 is a pumping pipe, 6 is a high water tank, and 7 is water supply. Tube, 8A and 8
B and 8C are water taps that open or close automatically or manually, 9A
9B and 9C are water supply facilities, and 10 is a dead water area.

Next, the operation will be described. The water tank 3 stores water resources supplied from the water main 1, and the water meter 2 measures the amount of water received from the water main 1. The water resource in the water receiving tank 3 is sterilized by injecting chlorine by the chlorine injecting machine 4, is sent to the elevated water tank 6 through the pumping pipe 5, and is stored therein. , 9C. Then, in each of the water supply facilities 9A, 9B, 9C, water is automatically or manually supplied from the water taps 8A, 8B, 8C and used for drinking water or the like.

As described above, in the water supply in the building, water storage tanks such as the water receiving tank 3 and the elevated water tank 6 are provided, and a certain amount of clean water supplied from the waterworks is stored in these water tanks. If the amount of water stored in these water tanks is extremely large compared to the amount of water supplied, the frequency of water replacement in the tank will decrease and the water will remain stationary for a long time, and residual chlorine contained in the water will be lost. It becomes unfavorable drinking water, so-called dead water. On the contrary, when the stored water amount is extremely smaller than the water supply amount, smooth water supply cannot be performed unless the pump is frequently operated.

Therefore, as a measure of how much water is optimal in a building, generally the capacity of the water tank is
1/2 or 4 hours of water supply per day in the receiving tank,
In a high water tank, it is 1/10 or 1 hour, and the amount of water stored in the water tank is controlled by opening the valve when the amount of water stored reaches a predetermined level and closing the valve when the water level reaches a predetermined level.

No water used for days. Therefore, the accumulated water determination means 4
9 identifies the accumulation position and accumulation capacity of the accumulated water from the piping data. In this case, the accumulated water determination means 49 will check the presence of accumulated water from the water supply branch pipe 7C at the end away from the elevated water tank 6. Water tap 8G, water tap 8H, water tap 8
Since water is not supplied for 3 days in I,
3 to o4, o4 to c3, a3 to d3, b3 to e3, and c3 to f
It is determined that the accumulated water exists in the section of No. 3. Next, the existence of accumulated water in the water supply branch pipe 7B will be examined. Since the water tap 8E has not been supplied with water for 3 days, it is determined that there is accumulated water in the section from b2 to e2 shown in FIG. 7. Next, the presence of accumulated water in the water supply branch pipe 7A will be examined. Hydrant 8
Since water is not supplied for 3 days at A, water tap 8B, and water tap 8C, the section from o2 to c1 and a1 shown in FIG.
From d1 to d1, from b1 to e1 and from c1 to f1 the accumulated water exists.

The accumulated water judging means 49 then calculates the volume of accumulated water by the following equation (1) with reference to the pipe data.

V = π · (A / 2) ² · L (1)

Here, V is the volume of accumulated water, A is the nominal diameter of the pipe, and L is the length of the pipe.

Based on the section where the accumulated water is present and the capacity of the accumulated water determined by the accumulated water determination unit 4 in this way, the water faucet control amount calculation unit 50 determines the position of the water faucet that discharges the accumulated water and its position. Calculate the time to open the faucet.
