Description

Leakage blocking system using RFID [

The present invention relates to a water leakage prevention system using RFID, and more particularly, to a water leakage detection system in which a water leakage sensor is installed in a piping embedded in a building to enable data communication, It is possible to minimize the leakage amount by blocking the piping when the leakage occurs, and to easily confirm the accurate leak position.

Particularly, according to the present invention, a passive RFID that does not require a separate power supply is installed in a pipe, and when it is impossible to communicate with a specific RFID, it is determined that a leak occurs at a point where the RFID is installed. And more particularly, to a leak-barrier system using RFID that can monitor the occurrence of a leak in real time and quickly block the supply of water to the pipe.

Generally, buildings such as apartments, office buildings, and hotels are provided with piping for water supply, hot water supply, and heating water supply, and most of these pipelines are embedded in the floor or wall.

On the other hand, at connection points of various pipes installed in a building, leakage may occur due to change in water pressure and aging of pipes.

In order to minimize the damage caused by such leakage, it is necessary to regularly check the occurrence of leakage by using a leak detector. However, as described above, since most of the piping is constructed by being embedded in the floor or the wall, There were many difficulties to do.

Because of this, it is not easy to grasp leaks or leaks at the beginning of leaks. In most cases, leaks occur and the leaks can be confirmed only if the leaks occur outside.

In addition, even if the leakage is confirmed, it is very difficult to find the point that causes the leakage because the point where the damage caused by the leakage is different from the point where the leakage occurs is different from the point where the leakage actually occurs.

As a result, the time, personnel, and material consumption of the renovation work due to leaks must be increased because the leakage point must be searched for a relatively large area centered on the point where the leakage is confirmed from the outside.

Particularly, in the case of a commercial building, there is a problem in that not only the direct damage due to the leakage but also the secondary damage amount increases because the leakage of the leaking water influences the sales of the resident company due to the renovation .

An example of a method of confirming leakage of a connection portion of a pipe is disclosed in Korean Patent Publication No. 10-1391762, " Leak detection member for liquid conveying pipe " (hereinafter referred to as " Prior Art " .

Specifically, the prior art allows the leak detection member installed to surround the connection portion of the pipe to detect the leakage of liquid in real time, so that the administrator can easily visually check whether or not the leak is visible.

However, there is a problem that the same method as the prior art is not applicable to the piping embedded in the floor or wall of the building.

The present invention provides a water leakage blocking system using RFID that can monitor the occurrence of water leakage in real time and quickly block water supply of the corresponding pipe.

An example of a leak-barrier system using RFID according to the present invention can be variously applied, and a most preferred embodiment will be described below with reference to the accompanying drawings.

FIG. 1 is a configuration diagram showing an embodiment of a leak-barrier system using RFID according to the present invention.

Referring to FIG. 1, a water leakage blocking system A using RFID includes a water supply pipe 100, a water leakage sensing unit 200, and a self-controlled irrigation closure 300.

The water supply pipe 100 is a pipe for supplying water to the inside of the building. The pipe is connected to a water pipe for supplying drinking water, a hot water supply pipe for supplying hot water, a heating water supply pipe connected to the boiler, Water supply pipe and so on. It goes without saying that the water supply pipe 100 can be changed to a pipe through which various kinds of fluids (water) move, such as a hot water supply pipe, a heating water supply pipe, a fire water supply pipe and the like according to the needs of those skilled in the art.

The leakage detection unit 200 may include a plurality of sensors in the water supply pipe 100 and may include a sensor for detecting leakage when the leakage occurs.

At this time, since the water leakage sensing unit 200 is formed in the water supply pipe 100 and buried in the building, when a separate power supply device is required, it may be difficult to replace it.

Therefore, the leak sensor for leak detection is configured to maintain a normal steady state at normal time without requiring a separate power supply, and to be electrically damaged by liquid at the time of leakage to become inoperable state It is preferable to include a passive RFID.

When the passive RFID is configured in the water leakage sensing unit 200, the RFID reader communicates with the plurality of water leakage sensing units 200. In the case where there is the water leakage sensing unit 200 that is disconnected from communication, It can be confirmed that a leak has occurred at the position.

The self-controlled irrigation closure part 300 includes a function of an RFID reader or an RFID reader. The self-controlled irrigation closure part 300 performs wireless communication with the RFID of the water leakage sensing part 200. When communication with a specific RFID is cut off, It can be determined that leakage occurs in the water supply pipe 100 at the point where the water supply pipe 200 is installed.

Accordingly, the self-regulating irrigation pipe 300 can prevent water from being supplied to the water supply pipe 100 when leakage of water from the specific water supply pipe 100 is detected, .

In addition, the present invention minimizes the damage area due to leakage, thereby facilitating subsequent maintenance such as maintenance work by the manager.

Specifically, the self-regulating irrigation closure 300 may include an on-off valve 310, an RFID reader 320, and a control module 330.

The opening / closing valve 310 may be installed at one side of the water supply pipe 100 (water supply portion) to supply water to the inside of the water supply pipe 100 or shut off the water.

The RFID reader 320 performs wireless communication with the passive RFID of the leakage sensing unit 200 and can receive identification information of the RFID. Here, the RFIF reader 320 can recognize up to 200 m by using four phased array antennas, but it is sufficient that the RFIF reader 320 can detect RFIDs in a specific area in a building in consideration of errors and the like .

The control module 330 may control the opening / closing valve 310 to shut off the supply of water to the water supply pipe 100 when communication with at least one of the plurality of RFIDs installed in the water supply pipe 100 is stopped.

Therefore, the leak-barrier system (A) of the present invention can prevent the damage area from spreading due to continuous leakage by blocking the supply to the water supply pipe (100) at the time of leakage.

Hereinafter, a process of registering the passive RFID in the self-controlled irrigation unit 300, a process of updating the data according to the maintenance work in case of leakage, and a process of restarting the water supply to the water supply pipe 100 will be described.

Fig. 2 is a block diagram showing another embodiment of the self-regulating irrigation closure shown in Fig. 1. Fig.

Referring to FIG. 2, the self-regulating irrigation closure 300 may further include a data input module 340 for registering a passive RFID.

The data input module 340 may include a key input unit 341 operated by a user (administrator) and a data communication unit 342 performing wired / wireless communication with the outside.

The control module 330 checks the design information of the water supply pipe 100 inputted to the data input module 340 by the operation of the operator when constructing the water supply pipe 100, It is possible to generate and register the RFID arrangement information matching the RFID identification information installed in the RFID tag and the position information in which the RFID is installed.

Therefore, if the communication with the specific RFID is cut off due to the occurrence of the leakage, the position of the RFID which is disconnected based on the RFID placement information can be confirmed.

The position of the RFID identified by the communication disconnection is the position where the leakage occurs, and the leakage information including the position information can be transmitted to the administrator terminal carried by the manager who manages the pipe.

Thereafter, when the RFID interrupted by the operator is replaced with a new product, the administrator can update the existing RFID information with the new RFID information by using the data input module 340.

When the identification information of the new RFID is inputted through the data input module 340 while the open / close valve 310 is closed due to occurrence of leakage, the control module 330 transmits the RFID arrangement information Can be updated.

The control module 330 may resume the water supply to the water supply pipe 100 by controlling the on-off valve 310 when communication with all the passive RFIDs installed in the water supply pipe 100 is resumed.

On the other hand, when the RFID arrangement information is updated by a non-specialist, the self-controlled irrigation closure part 300 may malfunction or become inoperable.

In order to prevent this, the self-regulating irrigation closure part 300 of the present invention may further include a key connection terminal 350 to which an administrator's encryption key carried by an administrator is connected. Here, although the physical key may be used as the manager encryption key, it is preferable to use an electronic key in which the encrypted IC chip is embedded for copy protection and security.

The control module 330 can approve the update of the RFID placement information when the manager authentication key is connected to the key connection terminal 350 and the administrator authentication is completed. Here, the administrator authentication can be performed only by connection of the administrator's encryption key, and if necessary, the administrator can perform authentication by using a key input unit 341 to receive the password.

In the above, the self-controlled irrigation closure unit 300 has been operated independently of the operation of the administrator, and the following description will be made about a method of performing the monitoring operation at the remote site.

Fig. 3 is a configuration diagram showing another embodiment of Fig. 1. Fig.

Referring to FIG. 3, the leakage prevention system A may further include a central controller 410 and a remote management server 420.

The central controller 410 interlocks with a plurality of self-controlled irrigation closure parts 300 installed in each building area to monitor whether or not a leaking water is leaked to each area, and receives position information of a point where leakage occurs from the self- .

The remote management server 420 interlocks with the central controller 410. When the water leakage occurs, the water supply pipe 100 can generate leakage notification information by matching location information with the constructed design information, (430).

Accordingly, the administrator carrying the administrator terminal 430 can confirm the leakage notification information transmitted from the remote management server 420 and proceed with the maintenance work for the corresponding area. Then, as described above, the self- 300 to update the water supply to the water supply pipe 100 to be restarted.

4 is an assembled perspective view showing an embodiment of the water supply pipe shown in FIG.

Referring to FIG. 4, the water supply pipe 100 may include a double pipe for detecting leakage including an external pipe 110, an internal pipe 120, a fluid fastener 130, and a water leakage sensing unit 140.

The outer tube 110 is connected by welding and is constituted by a tube having a sufficient stiffness in order to protect the inner structures in a state where the outer tube 110 is continuously connected by the welding portion w and is embedded in the floor or wall of the building .

In other words, the outer tube 110 prevents and protects the inner tube 120 from being damaged, and water, hot water, and heating water move through the inner tube 120, It is possible to prevent leakage even if damage or cracks occur.

Since the inner pipe 120 is inserted and arranged from one side of the outer tube 110 and is configured to be inserted without a joint portion, it is possible to originally exclude the joint portion, which is one of the biggest factors causing leakage.

In other words, it is possible to maximize the effect of preventing water leakage by preventing the occurrence of joints in the inner pipe through which the water moves.

At this time, since the inner tube 120 is made of a soft material, not only the insertion of the inner tube 120 from one side of the outer tube 110 is smooth, but also an excessive physical impact is generated between the inner tube 120 and the outer tube 110 Can be prevented.

Meanwhile, in spite of the double structure as described above, when the inner pipe 120 itself is defective, if the inner pipe 120 is damaged due to the operator's mistake in the construction process, the pressure change due to the hydraulic pressure change Leakage may occur due to, for example, damage to the inner pipe 120.

The leakage water thus generated may flow out to the outside through the welded portion w of the outer tube 110 or may move inside the outer tube 110 and may flow out to the outside from the end of the outer tube 110 connected thereto.

In order to prevent this, the present invention can constitute a plurality of fluid fasteners 130 between the inner pipe 120 and the outer pipe 110.

The fluid fastening portion 130 can prevent the leakage of flowing water by dividing the space between the inner pipe 120 and the outer pipe 110 into the unit space portion 111 by cutting the space between the inner pipe 120 and the outer pipe 110 at regular intervals in the longitudinal direction .

The leakage sensing portion 200 is formed in each unit space portion 111 partitioned by the fluid fast guide portion 130 and detects the leakage of the internal pipe 120 formed in the unit space portion 111, Or may be configured on the inner surface of the outer tube 130 or on one side of the fluid fast guide 130 as shown in FIG.

Hereinafter, the coupling relationship between the respective components shown in FIG. 4 and the embodiments will be described in detail.

5 is a partially cutaway perspective view showing an embodiment of the main part of FIG.

5, the fluid fastening portion 130 may be formed in a film shape corresponding to the shapes of the outer tube 110 and the inner tube 120. In the process of inserting the inner tube 120 into the outer tube 110, It is preferable to be made of a soft material so as not to cause damage to the welded portion w of the welded portion 110.

5, when the inner tube 120 is inserted into the outer tube 110, when the inner tube 120 is deformed due to frictional force during the insertion of the inner tube 120 into the outer tube 110, This gap prevents the adjacent two unit space parts 111 from maintaining a spatial blocking state, so that the leakage area can be diffused.

Hereinafter, a method for solving the problem will be described.

6 is a partially cutaway perspective view showing another embodiment of FIG.

Referring to FIG. 6, the fluid fastening portion 130 may be formed of a mohair plate 131 using a mohair.

In the case where the fluid fastening portion 130 is formed of the mohair plate 131, even if the mohair is deformed due to frictional force during the process of inserting the inner tube 120 into the outer tube 110, It is possible to improve and maintain the blocking effect between the two unit space portions 111 which are formed by the two unit space portions 111.

On the other hand, in the case of the mohair plate 131, if the leakage amount is small, it can sufficiently prevent the movement of the fluid. However, if a considerable amount of leakage occurs, due to the structural characteristics of the mohair, The leakage can be diffused to the neighboring unit space portion 111 through the gap.

Hereinafter, a method for solving the problem will be described.

7 is a partially cutaway perspective view showing another embodiment of FIG.

Referring to FIG. 7, the fluid fast guide portion 130 may be composed of a ring-shaped double-plate film. In other words, by constituting the fluid fast-moving part 130 shown in Fig. 5 in two, the blocking effect between the adjacent two unit space parts 111 can be improved.

At this time, when the fluid fastening portion 130 is applied in the double-wall configuration, the frictional force is increased in the process of inserting the inner tube 120 into the outer tube 110, so that the smooth insertion may not be performed.

Thus, by forming at least one valve membrane of the double-layer membrane of the fluid fast guide portion 130 from the inclined plate 132, the inner tube 120 can be inserted more smoothly.

Also, even if leakage of a considerably large amount of water occurs due to the inclined plate 132, it is possible to prevent leakage of the water to the neighboring unit space portion 111.

At this time, the other plate of the double-layer plate of the fluid fast guide 130 may be formed of a plate-like plate as shown in FIG. 7, but in order to solve the problems occurring in the plate- And a mohair plate 131 as shown in FIG.

In this way, it is possible to prevent the occurrence of leakage by using a double pipe type water supply pipe, and to minimize the spread of leakage when leakage occurs.

The leakage blocking system using the RFID according to the present invention has been described above. It will be understood by those skilled in the art that the technical features of the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

It is to be understood, therefore, that the embodiments described above are in all respects illustrative and not restrictive.
