For example, water that can be used as drinking water or water is supplied through a water pipe, and general water or industrial water can be supplied through a pipe connected to a ground water pipe or a storage tank.

Such water supply is provided by a control valve installed at a proper position of each supply pipe and an opening / closing valve or cock installed at the end of each supply pipe. That is, the water supplied through each supply pipe is supplied to the actual consumer through each valve or cock by water pressure.

First, when a leak occurs in each supply pipe installed in each household, there is a problem that it can not be detected until the occupant finds it by the naked eye.

Further, if the detection of the leakage is delayed, the follow-up action is delayed, which causes serious damage.

In addition, due to the constant or increased water pressure inside the supply pipe, leakage occurs naturally in various mechanisms such as the toilet in the toilet, and the amount of the leakage is increased, and the amount of leakage due to failure to detect the leakage in a timely manner There is a problem that economic loss is caused

Various techniques have been developed to detect such leaks and speed up follow-up.

8 is a flowchart for explaining a leakage detection method according to the present invention.

In the leakage detection method according to the present invention, as shown in FIG. 8, a leak detector using a compression coin is installed at the bottom of the pit room (S110), and a pressure value of the water supply / hot water / heating / S130).

Then, the control unit 240 of the leakage detection control device 200 determines the leakage detection (S150).

The determination result (S150) The control unit 240 determines whether leakage from the leak detector 190 is present (S170).

The control unit 240 controls the water supply control valve 110, the hot water control valve 120, the heating control valve 130, and the recovery valve 130 through the valve control unit 230, The control valve 140 is controlled to shut off the water supply / hot water / heating / recovery valve (S190).

However, if it is determined in step S170 that the water leakage from the water leakage sensor 190 is not detected, the control unit 240 calculates a change in the pressure value of the water supply control valve 110 and determines whether the pressure change is greater than a predetermined pressure value in step S210. At this time, the pressure value changes of the water supply inlet pipe sensor 151 and the water supply / discharge pipe sensor 152 are respectively determined.

If it is determined at step S210 that the change in the pressure value of the water supply control valve 110 has changed by more than the set pressure value, the water supply control valve 110 is shut off at step S230.

However, if it is determined at step S210 that the change in the pressure value of the water supply control valve 110 has not been changed by more than the set pressure value, it is determined whether the change in the pressure value of the hot water control valve 120 has changed by more than the set pressure value ). At this time, changes in the pressure values of the hot water inlet pipe sensor 161 and the hot water discharge pipe sensor 162 are respectively determined.

If it is determined that the change in the pressure value of the hot water control valve 120 has changed by a predetermined pressure value or more (S250), the hot water control valve 120 is shut off (S270).

However, if the change in the pressure value of the hot water control valve 120 does not change by more than the set pressure value, the change in the set pressure value of the heating control valve 130 and the recovery control valve 140 is calculated (S250) (Step S290). At this time, changes in the pressure values of the heating water inlet pipe sensor 171, the heating water discharge pipe sensor 172, the recovery inlet pipe sensor 181, and the recovery / delivery pipe sensor 182 are respectively determined.

If the change in the pressure value of the heating control valve 130 or the recovery control valve 140 is changed by more than the set pressure value, the heating control valve 130 or the recovery control valve 140 is shut off (S310).

However, if the heating control valve 130 or the recovery control valve 140 does not change as much as the change in the pressure value is determined, the water control valve 110, the hot water control valve 120, the heating control valve 130, And the recovery control valve 140 are not blocked and report the abnormality through the communication unit 250. [ In such cases, it may be caused by abnormal boiler or sensor error.

On the other hand, after the water supply control valve 110, the hot water control valve 120, the heating control valve 130 and the recovery control valve 140 are shut off, the abnormal situation is reported to the administrator (computer) through the communication unit 250 S350). At this time, the water supply inlet pipe sensor 151, the water discharge pipe sensor 152, the hot water inlet pipe sensor 161, the hot water discharge pipe sensor 162, the heating water inlet pipe sensor 171, the heating water discharge pipe sensor 172 The hot water inlet pipe, the hot water inlet pipe, the heating water inlet pipe, and the waterproof discharge pipe, depending on the result of sensing from the return inlet pipe sensor 181 and the recovered discharge pipe sensor 182, Thereby solving the leakage problem of the inlet piping and the recovery piping.

Then, it is determined whether the problem is solved (S370). If the problem is solved, the shutoff valve is opened (S390).

The control unit 240 compares the set reference values of the first to fourth pressure sensors 150, 160, 170 and 180 with the reference values of the water supply inlet pipe sensor 151, the water supply discharge pipe sensor 152, The sensor 161 and the hot water discharge pipe sensor 162 from the hot water discharge pipe sensor 162, the heating water inlet pipe sensor 171, the heating water discharge pipe sensor 172, the recovery inlet pipe sensor 181 and the recovered discharge pipe sensor 182 And comparing the change of the pressure value.
Installing a water leak detector on the floor of the pit room (S110), setting a pressure value of the water supply / hot water / heating / recovery control valve (S130);
Determining whether a leak from the water leakage detector 190 or leakage from the water supply control valve 110, the hot water control valve 120, the heating control valve 130, and the recovery control valve 140 is detected ;
If the water leakage from the water leakage detector 190 is not detected, the water supply control valve 110, the hot water control valve (not shown) 120, the heating control valve 130, and the recovery control valve 140 to stop the control valve that has changed by a predetermined pressure value or higher, and report the control valve to the computer through the communication unit. And
Leak detection control method using a leak detection control system, characterized in that comprises; opening the control valve blocked when the leak detection problem is solved.
12. The method of claim 11,
The leak detector has a plurality of holes 191 formed on a bottom surface thereof and a sensor hole 192 formed perpendicularly to a central portion thereof and the plurality of holes 191 A magnet 194 is placed on the upper portion of the compression coin 193 and a sensor 194 for sensing the magnetism of the magnet 194 is mounted on the sensor hole 192. [ The position of the magnet 194 is moved upward when the compression coin 193 is swollen as the compression coin 193 absorbs water leaking through the plurality of holes 191 Wherein the sensor (195) senses leakage of the magnet by sensing the magnetism of the magnet.
12. The method of claim 11,
The set pressure value R of the water supply control valve 110, the hot water control valve 120, the heating control valve 130 and the recovery control valve 140 is not a leakage value from the leak detector 190, And reporting to the computer that there is no abnormality in the water supply control valve 110, the hot water control valve 120, the heating control valve 130, and the recovery control valve 140, A leak detection control method using a leak detection control system.
