However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only this embodiment serves to complete the disclosure of the present invention, and those of ordinary skill in the art to which the present invention pertains. It is provided to fully inform the person of the scope of the invention, and the present invention is only defined by the claims.

Like reference numerals refer to like elements throughout.

1 is a perspective view showing the configuration of a leak detection device using a vibration sensor according to an embodiment of the present invention, and FIG. 2 is a leak detection film of the leak detection device using a vibration sensor according to an embodiment of the present invention. This is a floor plan for

Referring to FIG. 1 , a leak detection device using a vibration sensor according to an embodiment of the present invention includes a leak detection film 110 , a leak detection and vibration detection module 120 , and a wireless communication module 130 .

The leak detection film 110 is wrapped in a band shape at the connection part of the pipe through which the chemical substance passes, and resistance change occurs due to the leakage of the chemical substance from the connection part of the pipe.

The leak detection film 110 is a flexible film 111 in which a conductive wire pattern capable of detecting a change in resistance is wired. As an example of FIG. 2 , the conductive wire pattern wired to the film 111 is the first and second electrode terminals 112 and 113 , and the first electrode pattern 112a disposed connected to the first electrode terminal 112 . , connected to the second electrode terminal 113 and disposed in parallel between the first electrode patterns 112a may be formed of a second electrode pattern 113a. That is, the conductive wire pattern is not limited to FIG. 2 . The first and second electrode terminals 112 and 113 are inserted into the leak detection and vibration detection module 120 to be described later and are in electrical contact. After the leak detection film 111 is wrapped around the tube in the form of a band, it is inserted into the insertion hole 121 of the leak detection and vibration detection module 120 to be described later to make electrical contact.

In addition, in the present invention, the leak detection film 110 uses the flexible film 111 to provide excellent flexibility and wrap it around the tube in the form of a band to detect the leakage of chemicals leaking from the tube at the nearest location. There are technical characteristics of what can be done, and the shape of the conductor wire capable of detecting the change in resistance of the leak detection film 110 can be applied to various other pattern shapes.

The leak detection and vibration detection module 120 has a built-in leak detection part and a vibration detection part, and is mounted on the connection part of the pipe through which the chemical substance passes or the pipe area adjacent to the connection part of the pipe. At this time, various mounting members for mounting the leak detection and vibration detection module 120 to the tube may be applied.

Here, the leak detection and vibration detection module 120 is integrally formed with the leakage detection part and the vibration detection part being built into one housing. At this time, the leak detection and vibration detection module 120 includes a housing for protecting the leak detection unit and the vibration detection unit from the outside, and an insertion hole 121 is formed in the housing, and a leakage detection film is formed in the insertion hole 121 . 110 is inserted and electrically connected to the leak detection unit, and the leak detection unit detects the leakage by detecting a change in resistance caused by contact with the leak detection film 110 .

In addition, a passage 122 through which gas flows may be formed in the housing when the gas detection unit, which will be described later, is further included in the leak detection and vibration detection module 120 .

On the other hand, a leak occurs in the pipe before the chemical leaks, and after gas escapes through the gap, the leak occurs. That is, when a gap is generated in the pipe, the gas of the chemical substance leaks out of the gap first because the flow rate of the gas is higher than that of the chemical substance of the liquid, and then the chemical substance of the liquid leaks after a predetermined time has elapsed.

Therefore, in the present invention, in order to detect the gas escaping before leakage and to quickly determine that a gap has occurred in the pipe, the vibration detection unit together with the leakage detection unit is integrated into the leak detection and vibration detection module 120. It is possible to detect gas first by mounting the leak detection and vibration detection module 120 in the pipe connection part and its vicinity. Here, the vibration sensing unit may be referred to as a vibration sensor, and may be configured to be in contact with the leak detection film 100 to sense minute vibrations of the leak detection film 100 .

That is, in the vibration sensing unit, the gas that escapes from the gap in the pipe before the leakage occurs collides with the leakage detection film 110 to generate minute vibrations in the leakage detection film 110, and vibration of the leakage detection and vibration detection module 120 The sensing unit detects minute vibrations of the leak detection film 110, and a gap is formed in the tube, and it is determined that gas has leaked from the gap.

Therefore, in the present invention, when the vibration sensing unit detects minute vibrations of the leak detection film 110 , it is possible to quickly respond to the occurrence of leakage and prevent accidents in advance because the leakage occurs before the leakage occurs. In other words, the leak detection device using the vibration sensor of the present invention can respond to the initial response.

The wireless communication module 130 wirelessly communicates the leak detection signal or vibration detection signal detected by the leak detection and vibration detection module 120 to the management server, which is an external device, and the LED module (511,512,513,514), and transmits the wireless communication module ( The connection jack 131 of the electric wire connected to 130) is connected to the jack insertion hole of the leak detection and vibration detection module 120 .

Here, the wireless communication from the wireless communication module 130 to the LED modules 511,512, 513,514 uses LoRa (Long Range) communication technology, which is a low-power long-distance communication technology that enables objects to communicate with each other. Internet (loT) dedicated network can be used.

3 is a perspective view illustrating a state in which a leak detection device using a vibration sensor is mounted on a tube according to an embodiment of the present invention, and FIG. 4 is a leak detection device using a vibration sensor according to an embodiment of the present invention. It is a perspective view showing the area where the sensing film is mounted on the connection part of the tube.

In industrial sites such as actual factories, pipes are used to transport chemicals, and a plurality of pipes are connected to each other to allow pipes to pass through various areas within the factory. At this time, leakage is generated at the connection part of the pipe.

Therefore, in the present invention, the leak detection film 110 is mounted on the connection part of the pipe or the pipe region (the outer circumferential surface of the pipe) adjacent to the connection part in a band shape to quickly detect the gas leaking from the connection part of the pipe.

Here, although a general gas detector is installed in the factory, when the amount of gas leaking from the connection part of the pipe is small, it is diluted with air and the gas detector installed in the factory does not detect the gas leaking from the connection part of the pipe.

And, when the distance between the gas sensor and the connection part of the pipe through which the gas leaks is long, it takes a considerable amount of time for the gas sensor to detect the leaked gas.

Therefore, the gas detector installed in the factory cannot detect the gas leaking from the connection part of the pipe or it takes a considerable amount of time to detect it, so it cannot be quickly determined that a gap has occurred in the connection part of the pipe, so it is not suitable to deal with the risk of an accident. not.

In the present invention, the leak detection film 110 and the leak detection and vibration detection module 120 are mounted on the connection part of the pipe or in the pipe area adjacent to the connection part to quickly detect the gas leaking from the connection part of the pipe by vibration detection. able to respond quickly to

Accordingly, referring to FIG. 3 , when the flange 230 is used as a connection part connecting the first tube 210 and the second tube 220 , the leak detection film 110 is wrapped around the flange 230 in a band shape and the leakage The detection film 110 is inserted into the insertion hole of the leak detection and vibration detection module 120 to electrically connect the leak detection unit and the leakage detection and vibration detection module 120 and the wireless communication module 130 are electrically connected. The wireless communication module 130 may be mounted on the first tube 210 . Here, since the electrical connection wiring between the leak detection and vibration detection module 120 and the wireless communication module 130 can be varied, it is not specifically illustrated in FIG. 3 .

Therefore, the gas leaking from the gap that may exist in the connection part is quickly detected by the vibration detection unit of the leak detection and vibration detection module 120, and the leakage after the gas leak is detected by the resistance change of the leakage detection film 110 in the leakage detection part. that can be detected.

Referring to FIG. 4 , the leak detection film 110 includes a flange 230 area (A) that is a connection part of the tube, a first tube 210 area (B) and a second tube 220 adjacent to the flange 230 . It is mounted in the form of a band in one of the areas (C) to quickly detect gas or liquid leaking from the connection part.

5 is a block diagram illustrating a first example of a leak detection system using a leak detection device using a vibration sensor according to an embodiment of the present invention, and FIG. 6 is a configuration block diagram showing a vibration sensor according to an embodiment of the present invention. It is a structural block diagram showing a second example of a leak detection system using a leak detection device.

As described above, the leak detection system according to an embodiment of the present invention can be configured in two forms. As shown in FIG. 5 in the first form, the leak detection and vibration detection module 120 including the leak detection film 110, the leak detection unit 125 and the vibration detection unit 126, the control unit 127, the wireless A leak detection device 100 using a vibration sensor consisting of a communication module 130; and an LED module 510 .

The LED module 510 includes a lighting unit composed of two colored LEDs and a white LED among colored LEDs including red, green, and blue; a control unit (not shown); and a wireless communication unit (not shown).

Therefore, in the first type of leakage detection system, the vibration detection signal detected by the vibration detection unit 126 of the leakage detection and vibration detection module 120 is input to the control unit 127, and the wireless communication module 130 from the control unit 127 ) through the first wireless communication network 501, the vibration detection signal transmitted to the wireless communication unit of the LED module 510 and transmitted to the wireless communication unit is input to the control unit, and the control unit is one of the two colored LEDs. Turn on the colored LED.

In addition, the leakage detection signal detected by the leakage detection unit 125 of the leakage detection and vibration detection module 120 is also input to the control unit 127, and the control unit 127 connects the first wireless communication network through the wireless communication module 130. The vibration detection signal transmitted to the wireless communication unit of the LED module 510 and transmitted to the wireless communication unit is input to the control unit, and the control unit turns on the other colored LED.

For example, when the two colored LEDs are red and blue, when the vibration detection signal is output from the vibration detection unit 126, it is transmitted to the wireless communication unit of the LED module 510 through the first wireless communication network, and The control unit lights a red LED to alert the workers in the factory that gas has leaked.

And, when the leak detection signal output from the leak detection unit 125 is transmitted to the wireless communication unit of the LED module 510 through the first wireless communication network, the control unit of the LED module 510 lights a blue LED to inform the operator. to indicate that a leak has occurred.

This first type of leak detection system wirelessly transmits a detection signal directly to the leak detection film 110 and the LED module 510 to illuminate the tube in which the leak detection and vibration detection module 120 is installed. By changing the illumination color of the illuminating LED module 510, it is possible to quickly recognize the point where the leakage has occurred in the factory.

Here, the first wireless communication network may be a communication network capable of performing LoRa communication.

As shown in FIG. 6 , the second type of system is a leak detection and vibration detection module 120 including a leak detection film 110 , a leak detection unit 125 and a vibration detection unit 126 , a control unit 127 , and wireless communication. A leak detection device using a vibration sensor consisting of a module (130); And the LED module 510, is configured to include a management server (505).

Here, the management server 505 includes a wireless communication module 130 .

In this system, the LED module 510 is composed of a lighting unit consisting of two colored LEDs and a white LED among colored LEDs including red, green, and blue, and does not include a wireless communication unit.

Therefore, in the leak detection system of the second type, the vibration detection signal detected by the vibration detection unit 126 of the leakage detection and vibration detection module 120 is transmitted through the control unit 127 and the wireless communication module 130 through the second wireless communication network. is transmitted to the management server 505 using , and the management server 505 lights one of the two colored LEDs of the LED module 510 .

In addition, the leak detection signal detected by the leak detection unit 125 is also transmitted to the management server 505 using the second wireless communication network through the control unit 127 and the wireless communication module 130, and the management server 505 is The other one of the two colored LEDs of the LED module 510 is turned on.

Accordingly, the management server 505 receives the detection signal from all the leak detection and vibration detection modules 120 installed in the industrial site to the second wireless communication network, and controls all the LED modules 510 in the industrial site to detect gas or leak. can be delivered to the operator by changing the color of the LED light.

In addition, the vibration detection signal is transmitted to the management server 505 before the leak detection signal, and the management server 505 determines that a gap has occurred in the pipe due to the transmission of the vibration detection signal and can take various measures. At this time, the management server 505 may determine that a gap has occurred and may predict that the leakage will occur after a predetermined time. Here, the form of the notice is that the management server 505 transmits a notification message to the mobile phone of the worker, the management server 505 posts a notification post on a bulletin board connected to the network in the industrial site, or the management server 505 sends a notification message to the operator's mobile phone. You can make a call to the repair team or an external company to leave a notification voice, and broadcast to evacuate at the same time as a notification through a broadcast speaker for quick evacuation of unrelated workers at the industrial site. The above-mentioned notification is to inform that the leak is generated after a predetermined time due to the occurrence of a gap in the tube.

In the first and second types of leak detection systems, the LED module 510 lights a white LED for lighting in an industrial site when gas detection and leakage detection are not performed.

On the other hand, the leak detection and vibration detection module 120 of the leak detection device 100 using the vibration sensor may further include a gas detection unit that directly detects the chemical gas escaping from the gap of the pipe. In this case, there is an advantage in that gas leaking from the gap in the pipe can be detected more precisely and quickly by detecting the vibration caused by the gas as well as directly detecting the gas.

That is, in the leak detection device using the vibration sensor according to an embodiment of the present invention, when a detection signal is generated from one of the vibration detection unit and the gas detection unit, it can be determined that a gap has occurred in the pipe, so that a quick response is possible. .

In addition, in the present invention, the leak detection and vibration detection module 120 may be implemented as a module by integrating the leakage detection unit, the vibration detection unit, and the gas detection unit together in one housing.

7 is a view of an example in which a leak detection device and an LED module using a vibration sensor applied to a leak detection system using a vibration sensor using a vibration sensor according to an embodiment of the present invention are disposed in an industrial field.

For example, when a vibration detection signal or a leak detection signal is generated in the leak detection device 102 using the second vibration sensor installed in the second area, the second LED module 512 illuminates the second area with a white LED in red. Turn on the LED or blue LED to change the illuminating color. The operator can instantaneously detect the color of the illumination and investigate the connection part where the leak detection device 102 is installed using the second vibration sensor in the second area to make urgent repairs or to respond quickly.

Here, each of the leak detection devices 101, 102, 103, and 104 using the first to fourth vibration sensors assigns a unique identification code to the leak detection signal and the vibration detection signal, and wirelessly transmits the first to fourth LED modules 511,512,513,514, and the first to the fourth LED module (511, 512, 513, 514) receives only the leak detection signal and the vibration detection signal to which the unique identification code of the leak detection device using the vibration sensor installed in each of the areas corresponding to it (they are illuminated) is received, and displays the lighting color change

For example, when the leak detection device 101 using the first vibration sensor and the first LED module 511 correspond to each other in the first area (in other words, the first LED module 511 is responsible for lighting the first area, When the leak detection device 101 using the first vibration sensor installed in the first area is illuminated), the leak detection signal with a unique identification code transmitted wirelessly from the leak detection device 101 using the first vibration sensor, and The vibration detection signal is received only from the first LED module 511 and not from the second to fourth LED modules 512, 513, and 514, so that when gas leakage or leakage occurs in the pipe of the first area, only the first LED module 511 is illuminated By changing , the operator can easily recognize that a gap has occurred in the pipe in the first area.

The LED module includes two colored LEDs and a white LED to illuminate the white LED when the vibration detection signal and the leak detection signal are not transmitted, and among the two colored LEDs when the vibration detection signal is transmitted Turns on one LED, and turns on the remaining LEDs among the two colored LEDs when the leak detection signal is transmitted,
The management server determines that a gap has occurred in the pipe due to the transmission of the vibration detection signal and uses a vibration sensor to predict that the chemical will leak after a predetermined time. delete delete delete delete delete delete delete delete delete
