[0041] FIG. 1 is a block diagram of a water leak detection device using a long-term storage multi-signal water leak detection module according to one embodiment.

[0042] According to one embodiment, a water leak detection device using a long-term storage multi-signal water leak detection module includes a water leak detection module (110) having a water-soluble or water-expandable material, and the water leak detection module (110) may include a water leak detection unit activated by a water leak, a signal transmitter operating according to the water leak detection unit; and a power supply unit connected to the signal transmitter or the water leak detection unit.

[0043] A water leak detection device may include at least a portion of a water leak detection sensor, a water leak detection device, a circuit, a semiconductor, a memory, a processor, a signal / data transceiver, etc. Each component of the water leak detection device may be physically / communicatively / electrically connected.

[0044] The water leak detection device can detect the presence or absence of a water leak in the target (101).

[0045] At least a portion of the leak detection device may be communicatively connected to at least a portion of the first leak management device (102) or the second leak management device (103).

[0046] According to one embodiment, the leak detection unit includes a soluble sensor or an inflatable sensor and can be mechanically activated by a leak without supplying power.

[0047] According to one embodiment, the operating sensitivity of the water leak detection unit can be adjusted or set according to the amount of moisture.

[0048] According to one embodiment, the water leak detection unit includes a plurality of sensors, and the plurality of sensors may have different moisture sensitivities.

[0049] According to one embodiment, the water leak detection device may further include a water leak management unit (120) that manages water leaks according to a signal transmitted from the water leak detection module (110).

[0050] The water leak management unit (120) may be communicatively connected to at least a portion of the first water leak management device (102) or the second water leak management device (103). The first water leak management device (102) or the second water leak management device (103) may include an administrator terminal or an administrator device such as a computing device.

[0051] FIG. 2 is a drawing showing a water leak detection device according to one embodiment.

[0052] Referring to Figure 2, the concept of a multi-signal leak detection module can be understood.

[0053] Referring to (a), the leak detection module (210) of the leak detection device may include a dual signal module. The leak detection module (210) may transmit multiple or multiple signals, such as a primary signal and a secondary signal.

[0054] The primary signal may include at least a portion of information indicating a warning level for water vapor generation. Referring to (b), the primary signal may be transmitted to the primary warning level area to initiate intensive management, such as increasing the number of patrols. The primary signal may be transmitted to an administrator terminal of an organization / manager conducting warning or monitoring for water leaks. The administrator terminal may include a device mounted on a vehicle.

[0055] The secondary signal may include at least a portion of information indicating the necessary steps for repairing a leak. Referring to (c), the secondary signal may be transmitted to initiate immediate repair work upon a secondary damage signal. The secondary signal may be transmitted to an administrator terminal of an organization / manager performing repair work on the leak, etc. The administrator terminal may include a server of an organization performing pipe repair / reinstallation / construction work, or a communication device connected to a server.

[0056] In a typical system, a specific device must be continuously powered and operating to detect a water leak. This means that even when no problem occurs, continuous power consumption can lead to battery discharge and various malfunctions, and when a leak does occur, appropriate detection and action may not be possible. A water leak detection module with long-term storage integrates the sensor, power supply, and signal generator. This module generates power and sends a signal to the management system only when a leak occurs, maximizing both power efficiency and sensor reliability. When a multi-signal water leak detection module is applied based on this principle, a primary signal is sent when a small leak, such as steam, occurs, and a secondary signal is sent when a leak sufficient to submerge the water leak detection module. This allows for efficient management of areas suspected of having a leak and prompt repair of areas where a leak has occurred.

[0057] Figure 3 is a block diagram of a water leak detection module according to an embodiment.

[0058] According to one embodiment, a long-term storage multi-signal water leak detection module (300) includes a water leak detection unit (301) having a water-soluble or water-expandable material, a signal transmitter (302) that operates according to the water leak detection unit, and a power supply unit (303) connected to the signal transmitter or the water leak detection unit, wherein the water leak detection unit (301) can be activated by a water leak.

[0059] According to one embodiment, the leak detection unit (301) includes a melting sensor or an expansion sensor and can be mechanically activated by a leak without supplying power.

[0060] According to one embodiment, the operating sensitivity of the water leak detection unit (301) can be adjusted or set according to the amount of moisture.

[0061] According to one embodiment, the water leak detection unit (301) includes a plurality of sensors, but the plurality of sensors may have different moisture sensitivities.

[0062] According to one embodiment, the signal transmitter (302) can transmit a signal to a leak management unit that manages a leak. The transmitted signal can include at least a portion of a signal indicating that a leak has been detected. The leak management unit can transmit control signals, signals regarding leak information, etc. to a leak management device, such as a first leak management device or a second leak management device.

[0063] To address the challenges of existing pipeline leak detection systems, leak detection modules can be manufactured as highly reliable, long-term storage-capable, power-integrated sensor modules. These modules integrate a leak detection unit (e.g., a sensor), power supply, and signal transmitter. Because they offer excellent long-term storage characteristics, they enable reliable operation without any malfunctions in the event of an actual leak. Furthermore, by multiplexing signaling systems based on the amount of leaks, leak detection modules enable efficient management of areas with anticipated leaks and prompt repairs in areas where leaks have occurred.

[0064] The leak detection module may include a multi-signal leak detection module, and more specifically, a method for manufacturing a leak detection module capable of long-term storage that transmits different signals depending on the amount of moisture it comes into contact with, and the method may be used to construct a pipe leak detection system that can efficiently manage leak prediction points and leak points.

[0065] Figure 4 is a drawing showing a leak detection module according to one embodiment.

[0066] Referring to Fig. 4, a circuit diagram of a water leak detection module can be seen.

[0067] A water leak detection module may include a water leak detection unit, a signal transmitter, a power supply unit, etc. The power supply unit may include a battery, etc. The water leak detection unit may include a switch, etc.

[0068] The leak detection module may include a single-signal leak detection module or the circuitry of a single-signal leak detection module. In standby mode, the signal transmitter and power supply of the leak detection module remain open. The leak detection module consumes no power during standby. This feature provides the advantage of excellent long-term storage performance.

[0069] Underground pipes remain buried for decades unless a problem arises. Leak detection modules, designed to detect leaks in underground pipes, have the same long-term storage performance as the leak detection modules, effectively minimizing maintenance costs. A leak detection unit can function as a kind of switch that activates when exposed to moisture.

[0070] Fig. 5 is a drawing showing a multi-signal leak detection module according to one embodiment.

[0071] Referring to Fig. 5, a circuit diagram of a multi-signal leak detection module can be seen.

[0072] The leak detection module may include a multi-signal leak detection module. The leak detection module may be designed as a multi-signal leak detection module. The leak detection module may be configured with two or more leak detection units, and the moisture sensitivity of each leak detection unit may be individually adjusted / set to operate in multiple different leak situations. This enables efficient management of potential leak locations and minimization of secondary damage through rapid repair work.

[0073] The water leak detection module can provide a highly reliable water leak detection module that can be stored for a long time and a multi-signal water leak detection module for efficient water leak accident management. The water leak detection module is normally inactive and stands by, but when a leak is detected from outside, it is activated to supply power and generate a signal. The water leak detection module is based on the principle that when inactive, the battery and the signal generator are in electrical non-contact and stand by without power loss, and when the detection unit is activated by a leak, the terminals of the battery and the signal generator make contact. Unlike systems that require a continuous power supply to detect water leaks, which incur maintenance costs due to power depletion, the water leak detection module with long-term storage of the present invention can fundamentally eliminate such losses.

[0074] Furthermore, the leak detection module can transmit signals in stages depending on the extent of the leak by adjusting the moisture sensitivity of the leak detection unit, which is the component that detects the leak. Based on the basic principles of a highly reliable leak detection module that can be stored for a long time, a multi-signal leak detection module can be manufactured. The leak detection module can also be used to effectively manage leak accidents, thereby minimizing damage caused by leaks.

[0075] Fig. 6 is a drawing showing a sensor of a water leak detection unit according to one embodiment.

[0076] Referring to Fig. 6, an embodiment of a leak detection module and a leak detection unit can be seen.

[0077] The leak detection unit may include a soluble sensor or an inflatable sensor. A soluble sensor incorporates a spacer made of a water-soluble material in the space between two terminals. When a leak occurs, the spacer dissolves, causing the two terminals to contact each other due to the elasticity of the spring. An inflatable sensor incorporates a material that expands due to moisture behind one terminal. When a leak occurs, the moisture-expandable material expands, pushing that terminal out and bringing it into contact with the other terminal. The leak detection unit is a simple implementation example of both the soluble and inflatable concepts, and can be modified as needed.

[0078] Fig. 7 is a drawing showing a joint-type water leak detection module according to one embodiment.

[0079] Referring to Fig. 7, the configuration of the joint-type leak detection module can be seen.

[0080] The leak detection module may include an articulated leak detection module. The leak detection module may be configured to control the moisture sensitivity of the leak detection unit in order to be implemented as a multi-signal leak detection module. The leak detection module may be configured to control the moisture sensitivity through variables such as the type and density of the leak detection material (e.g., a soluble material or an expandable material) of the leak detection unit. Fig. 7 illustrates a (soluble) prototype of the articulated leak detection module manufactured based on the embodiment of Fig. 6.

[0081] Referring to (d), the thickness of the articulated water leak detection module may be 2 cm. Referring to (e), the width x height of the articulated water leak detection module may be 7.5 x 10.5 cm. Referring to (f), the articulated water leak detection module may have a signal transmitter, a leak detection unit, and a power supply unit each in the shape of a cylindrical rod and arranged close to each other. The leak detection unit may include a leak inlet port having a circular shape or the like. At least a portion of each end of the signal transmitter, the leak detection unit, and the power supply unit may be connected to each other. Referring to (g), the articulated water leak detection module may be formed into joints to facilitate pipe attachment construction. The articulated water leak detection module may include a form in which the signal transmitter or the power supply unit rotates based on or about the leak detection unit.

[0082] Figure 8 is a drawing showing the moisture sensitivity adjustment of a water leak detection module according to one embodiment.

[0083] Referring to Fig. 8, an example of adjusting the moisture sensitivity of a joint-type water leak detection module can be seen.

[0084] The joint-type water leak detection module (800) is equipped with a cylindrical spacer made of a soluble material within the water leak detection unit, and when water leaks through the water leak inlet (801), the spacer dissolves and the water leak detection unit switch is turned ON, thereby operating the signal transmitter. The joint-type water leak detection module can be configured as a sample so that when the signal transmitter is operated, an LED light / light / light connected to the receiver is turned on.

[0085] Referring to the table in Fig. 8, two spacers with controlled densities of dissolved substances were manufactured / produced, and the time required from moisture inflow to module operation was confirmed. As a result, the low-density joint-type leak detection module (sample 1) took 10 seconds, and the high-density joint-type leak detection module (sample 2) took 3 minutes. In other words, the moisture exposure time for the leak detection module to operate could be adjusted to have an 18-fold difference. For this adjustment, the leak detection module can use not only the density of the embodiment but also the type and size of the material as variables. Based on these results, the leak detection module can multiplex the signal system of the multi-signal leak detection module.

[0086] Fig. 9 is a drawing showing a flexible leak detection module according to one embodiment.

[0087] Referring to Fig. 9, the shape of the flexible leak detection module can be seen.

[0088] The leak detection module can be directly attached to the pipe. For smooth attachment to curved surfaces, the leak detection module can be manufactured / produced in an articulated form, as shown in Fig. 7. Furthermore, it can also be manufactured / produced in a flexible form, as shown in Fig. 9. A flexible leak detection module can maximize installation convenience when attached to curved pipes.

[0089] Referring to (h) and (i), the length of the flexible leak detection module may be greater than the thickness of the flexible leak detection module. Referring to (j) and (k), at least a portion of the flexible leak detection module may be bendable, and has the advantage of being able to be attached without spacing to at least a portion of the pipe (e.g., a wall inside the pipe or a wall outside the pipe, etc.).

[0090] Fig. 10 is a drawing showing a water leak detection module according to an embodiment of the present invention.

[0091] Referring to Fig. 10, a water leak detection system using a multi / single signal water leak detection module can be seen.

[0092] Referring to (a1) and (a2), a method of operating a water leak detection system using a multi / single signal water leak detection module can be known.

[0093] Leak detection modules can be installed in locations with a high risk of problems, such as connection sections. Since they do not use power during standby, there is no maintenance required, such as battery replacement.

[0094] In the event of a leak, such as in (a2), the leak detection module may not operate / not respond to minute amounts of water vapor, and may operate / respond when a leak occurs that is large enough to submerge the module. The leak detection module may include a dual signal module that sends a primary signal (e.g., a caution signal) when water vapor is generated, and a secondary signal (e.g., a breakage signal) when a leak occurs.

[0095] Cases where a leak detection module's leak occurrence signal is received may include cases where a signal from a leak detection module in a damaged area is received from a patrol car in a pipe burial area. In this case, applying a dual signal module enables efficient management of the first-stage warning area.

[0096] When pipe repairs and leak detection modules are reinstalled, the leak detection module can be reinstalled while the pipe repair work is in progress. Since pipe repairs and leak detection module reinstallation are performed simultaneously, separate maintenance costs may be eliminated.

[0097] The multi-signal water leak detection module proposed in the present invention reduces maintenance costs due to battery depletion and ensures highly reliable operation without any malfunctions in the event of an actual water leak. Furthermore, multiplexing the signal system based on the amount of water leak allows for efficient management of areas where water leaks are expected and rapid repairs in areas where leaks have occurred. This efficient water leak detection system maximizes the efficiency of water supply through pipes and minimizes damage caused by water leaks.

[0098] Because single-signal leak detection modules transmit only one signal when a leak occurs, they require a single choice regarding the level of leakage at which they will activate. Activating them when a small leak occurs allows them to focus on the potential problem area and minimize secondary damage. Activating them when a leak requires repair work allows them to identify the precise timing of maintenance and initiate repairs.

[0099] The multi-signal leak detection module is a product that can have both of these advantages and can transmit signals appropriate for each situation by including multiple leak detection units as needed.

[0100] (a1) is a conceptual diagram of a dual-signal leak detection module, illustrating its potential application in actual heat pipe systems. When a minor leak or vapor occurs, the leak detection module transmits a first signal, indicating a warning level. This signal allows the management center to conduct focused management, such as increasing patrols in the area. When a serious leak occurs, the leak detection module transmits a second signal, indicating the need for repairs. This signal allows the management center to initiate rapid repairs.

[0101] Figure 11 is a flowchart of a leak detection method according to an embodiment.

[0102] According to one embodiment, each step of a water leak detection method using a long-term storage multi-signal water leak detection module can be performed by at least some of the components of the water leak detection device described above.

[0103] In step (1101), the water leak detection device can adjust or set the operating sensitivity according to the amount of moisture in the water leak detection unit.

[0104] In step (1102), the water leak detection device can detect a water leak using a water leak detection module having a water-soluble or water-expandable material.

[0105] A water leak detection module may include a water leak detection unit activated by a water leak, a signal transmitter that operates according to the water leak detection unit, and a power supply unit connected to the signal transmitter or the water leak detection unit.

[0106] According to one embodiment, the leak detection unit includes a soluble sensor or an inflatable sensor and can be mechanically activated by a leak without supplying power.

[0107] According to one embodiment, the water leak detection unit includes a plurality of sensors, and the plurality of sensors may have different moisture sensitivities.
