It is about a method.

In general, a common house such as a building or an apartment is equipped with various mechanical equipment and power supply equipment. Since most of the facilities in these buildings are exposed to electrical wiring, care must be taken to prevent water or chemical liquids from entering inside.

Various facilities in such a building are often installed in an isolated space, such as a machine room, so it is not easy to monitor by manpower. In particular, water or chemical liquids can be introduced into the installation through various causes and routes, so it is necessary to automatically monitor the leaks inside the building. Therefore, in order to quickly respond to such a leak problem, a plurality of leak sensors are often installed in a building to monitor whether or not a leak occurs.

However, some sensors may react sensitively or malfunction in the process of using a plurality of leaking sensors. In addition, the space where the sensor is not installed is inevitably exposed to the risk of leakage, and the possibility of leakage damage such as equipment damage, flooding, and leakage still remains. In addition, it is difficult to determine the exact level of the current leakage situation only by sounding an alarm immediately when the leakage is detected, and there is a limit in finding an appropriate countermeasure for each leakage situation.

It is provided. In addition, the leakage monitoring system 10 may further include a gateway unit 150 for mediating communication between the microcontroller unit 110 and the control server unit 130.

The microcontroller 110 collects various sensing signals received from the environment sensing unit 120, and includes a microcontroller unit (MCU) as a processor for this purpose.

The environmental sensing unit 120 is composed of a plurality of sensing units to detect environmental changes around the plurality of sensing units. When a significant environmental change is detected, each of the sensing units generates a sensing signal. Therefore, each of the plurality of sensing units may be installed at a specific location of a facility or a building that is easy to detect an environment change or requires monitoring.

In an embodiment, the plurality of sensing units may include a leak sensing unit 121, a humidity sensing unit 122, and a temperature sensing unit 123. Such sensing units may be provided with various types of sensors to detect environmental changes related to leakage monitoring.

In detail, the leak sensing unit 121 senses a leak factor to generate a leak signal. In this case, the sensing object of the leak sensing unit 121 is not limited to water (H ₂ O), and may be various chemical liquids such as flammable oil and corrosive liquid.

In an embodiment, the leak sensing unit may include at least one film type leak sensor. At this time, the film-type leak sensor detects a leak by using a principle that a short circuit occurs when moisture contacts the conductive pattern formed on the base film. It can be easily attached to walls, furniture, etc. as well as equipment. In addition, it can be reused by simply wiping off the moisture contacted, and can be used for measuring the water level when attached in a vertical direction with respect to the ground because it can sense a considerable distance when it is attached for a long time.

However, the leak sensor is not limited to this film type, and various types of leak sensors such as cable type, gauge type, acoustic leak sensor, and combinations thereof may be used.

The humidity sensing unit 122 may detect an increase in indoor moisture by increasing humidity by measuring indoor humidity in real time or at regular intervals. In addition, the amount of moisture in the indoor air may be calculated by measuring the time for which the indoor humidity is maintained above the predetermined humidity.

In order to sense these humidity factors, the humidity sensing unit 122 may include a humidity sensor, in which the electrical resistance value or capacitance value is changed by the amount of moisture absorbed by the polymer membrane electrode attached to the surface. An electric resistive humidity sensor or a capacitive humidity sensor may be included.

In detail, the temperature sensing unit 123 generates a temperature signal by sensing a temperature factor.

The temperature factor which is a sensing item of the temperature sensing unit 123 may include a normal room temperature. The temperature sensing unit 123 may also sense that the temperature decreases to become the dew point temperature or the humidity rises by measuring the indoor temperature in real time or at regular intervals.

In order to sense these temperature factors, the temperature sensing unit 123 may include a temperature sensor, which is formed of a semiconductor ceramic so that thermistor capable of precisely measuring a sudden change in resistance value according to temperature may be precisely measured. ) Temperature sensor and the like can be used.

In addition, the humidity sensing unit 122 and the temperature sensing unit 123 may be integrally formed using a temperature and humidity sensor capable of simultaneously measuring temperature and humidity.

When the plurality of sensing units 121, 122, and 123 as described above reach the preset reference value of each of the sensing units 121, 122, and 123 while sensing the change in the surrounding environment, Each of the three sensing units 121, 122, and 123 generates a unique sensing signal. That is, each of the leak sensing unit 121, the humidity sensing unit 122, and the temperature sensing unit 123 generates a leak signal, a humidity signal, and a temperature signal as its own sensing signals.

The leak signal, the humidity signal, and the temperature signal generated as described above are transferred from the environmental sensing unit 120 to the microcontroller 110, whereby the microcontroller 110 provides information on whether each of the sensing signals is generated. Will be collected.

The microcontroller 110 generates integrated sensing information based on the collected information, and the integrated sensing information is provided to the control server 130 through at least one communication network. In an embodiment, the communication network may include a first communication network N1 and a second communication network N2, and the first communication network N1 and the second communication network N2 are connected to each other by the gateway unit 150. Can be communicated with each other.

In detail, the first communication network N1 may be a wireless communication network, and more specifically, a LoRa (Long Range) communication network, which is an IoT communication network. In this case, the microcontroller 110 may be connected to the gateway 150 through the first communication network N1.

Of course, the first communication network (N1) is not limited to the LoRa communication network, but may be composed of a wired / wireless internet network, a mobile communication network, a broadcasting network, other wireless communication networks, and the like, such as Bluetooth, Zigbee, Communication networks such as infrared communication, radio frequency (RF) communication, Wi-Fi, and wireless LAN may be used. However, it is more preferable to use LoRa communication network for long distance low power communication.

In more detail, the second communication network N2 may be an external communication network, and may include, for example, a wired / wireless internet network, a mobile communication network, a broadcasting network, and other wireless communication networks. The gateway unit 150 may be connected to the control server unit 130 through the second communication network N2.

As described above, the gateway unit 150 serves to connect two different communication networks N1 and N2, and control communication speed, control traffic, and computer address between communication networks when communication is performed between the communication networks N1 and N2. Complex processing such as conversion is performed. In particular, when the first communication network (N1) is a LoRa communication network characterized by a small amount of data, intermittent transmission, low power, the microcontroller unit 110 by adjusting the frequency, speed, etc. that data is transmitted through the gateway unit 150 The integrated sensing information generated by the controller can be efficiently transmitted to the control server unit 130.

In addition, although not shown in FIG. 1, the leakage monitoring system 10 may further include a communication unit (not shown) for connecting the microcontroller 110 to the first communication network N1. In this case, the communication unit includes an IoT communication module, specifically, a LoRa communication module, which may be installed outside the microcontroller unit 110 or mounted inside the microcontroller unit 110.

The control server 130 monitors the leak situation of the building in real time based on the integrated sensing information received from the microcontroller 110, and determines the level of the current dangerous state when the leak occurs. .

In one embodiment, the control server 130 may include a server 131 and a database 132.

The server 131 is a device that receives integrated sensing information from the microcontroller 110 and determines a dangerous state. The server 131 includes peripheral devices such as the microcontroller 110, the environment sensing unit 120, and the output unit 140. Can be controlled. Therefore, a user in charge of leak monitoring or building management can access the server 131 and check the leak monitoring status in real time.

When the server 131 determines the dangerous state of the leak situation in stages based on the integrated sensing information, the server 131 generates various output signals according to the determined dangerous state.

In detail, the server 131 determines the risk state of the leak situation as one of three levels of low risk, medium risk, and high risk, and the level of the command transmitted through the output signal increases from low risk to high risk.

A database 132 may be connected to the server 131, and this database 132 serves to properly classify and store integrated sensing information received by the server 131. In addition, the database 132 may also serve to store facility-related information in which the plurality of sensing units 121, 122, 123, and 124 are installed.

Thus, the user can read the information stored in the database 132 at any time and refer to leak monitoring and building management. Specifically, the stored information is controlled by the control server 130 for the microcontroller 110 and the environment sensing 120. The control unit may be used as feedback information in controlling peripheral devices such as the output unit 140.

As described above, when the control server unit 130 generates an output signal, the output signal is transmitted to the output unit 140. Accordingly, the output unit 140 performs a warning operation in response to the output signal.

In one embodiment, the warning operation may be to transmit a notification message according to a dangerous state determined as one of low risk, medium risk and high risk. Specifically, the notification message may be transmitted to the user terminal U using a mobile communication network. As a result, the user can quickly recognize a dangerous state of the current leakage situation through the notification message and take appropriate countermeasures.

However, the warning operation is not limited to the transmission of the notification message. Alternatively, the warning operation may be performed by outputting an alarm sound or evacuation broadcast, receiving an accident at a fire station, or actively performing an operation such as fire extinguishing or ventilation. In another embodiment, different warning actions may be performed for low, medium, and high risks in the order of notification message transmission, alarm sound output, active drying (fan operation, ventilation, and the like).

3 is a block diagram schematically illustrating a leak monitoring system according to another exemplary embodiment of the present invention.

The leak monitoring system 20 according to the embodiment shown in FIG. 3 is the same as or similar to the leak monitoring system 10 according to the embodiment shown in FIG. 1 except that the configuration of the environment sensing unit and the installation position of some sensing units are different. Do. Therefore, the following description focuses on differences from the above-described embodiment, and details overlapping with the above-described embodiment will be described with reduced or omitted.

Referring to FIG. 3, the leak monitoring system 20 according to another embodiment of the present invention, like the leak monitoring system 10 described above, includes a microcontroller 210, an environment sensing unit 220, and a control server unit ( 230 and an output unit 240. In addition, the gateway unit 250 may be further provided between the microcontroller 210 and the control server 230.

The microcontroller 210 is a part for collecting various sensing signals received from the environment sensing unit 220 and includes a microcontroller unit (MCU) as a dedicated processor.

However, in the present exemplary embodiment, the temperature sensing unit and the humidity sensing unit are integrally formed to have a temperature / humidity sensing unit 212, and the temperature / humidity sensing unit 212 is a microcomputer instead of the environmental sensing unit 220. The controller 210 is different from the above-described embodiment in that it is provided.

This is the basic sensing factor in detecting environmental changes in the case of temperature and humidity, so that the temperature sensing unit and the humidity sensing unit operate in a complementary manner with other sensing units specialized for sensing the fire, power failure, and earthquake. This can be more effective.

Therefore, the temperature and humidity sensing unit 212 is provided in the microcontroller 210 to correct the change of the measured value of the leak sensing unit 221 or the like according to temperature and humidity, or to detect the leak sensing unit 221 or the like. The operation such as changing the set reference value may be performed through the microcontroller 210.

Meanwhile, other sensing units 222 other than the leak sensing unit 221 may be further added to the environmental sensing unit 220. In this case, the other sensing unit 222 may be another kind of sensing unit for leak monitoring, or may be a sensing unit for detecting fire, power failure, earthquake, etc., rather than leak monitoring.

The leak sensing unit 221 senses a leak factor, and the leak factor that is sensed may include at least one of the presence or absence of leakage, the size of water droplet formation, the increase and decrease of the leak amount, the leak length, and the leak duration. In one embodiment, the leak sensing unit 221 is provided with at least one film-type leak sensor may be attached in an appropriate form for each position that requires a leak monitoring.

In addition, the temperature / humidity sensing unit 212 senses the temperature factor and the humidity factor with one sensor, and in this case, the humidity factor may sense at least one of an indoor humidity and a duration of a predetermined humidity or more. Can sense the room temperature.

When the sensing factors are detected as significant environmental changes, the leak sensing unit 221 and the temperature / humidity sensing unit 212 generate a leak signal, a temperature signal, and / or a humidity signal, respectively. It is received by the microcontroller 210.

The microcontroller 210 collects information on whether each of the sensing signals is generated and generates integrated sensing information based on the information.

The integrated sensing information generated as described above is transferred from the microcontroller 210 to the control server 230 through the first communication network N1 and the second communication network N2 interconnected through the gateway 250. The first communication network N1 may be an IoT communication network, specifically, a LoRa communication network.

The control server unit 230 may include a server 231 and a database 232. In the case of the server 231, the risk state may be determined as one of low risk, medium risk, and high risk based on the received integrated sensing information. The controller generates an output signal according to the determined dangerous state. In addition, the database 232 serves to properly classify and store the integrated sensing information received by the server 231.

The output signal generated by the control server unit 230 is transmitted to the output unit 240, the output unit 240 sends a notification message according to the determined risk status of the low risk, medium risk and high risk to the user terminal (U) Can transmit

Hereinafter, a leak monitoring method according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 7.

As shown in FIG. 4, first, steps S11, S21, and S31 of sensing a leak factor, a humidity factor, and a temperature factor are performed.

In these steps, a leak factor, a humidity factor, and a temperature factor may be sensed by using the leak detector, the humidity detector, and the temperature detector.

In this case, the humidity factor and the temperature factor may be separately sensed by separate sensing units, or may be simultaneously sensed by the integrated temperature and humidity sensing unit.

Specifically, the leakage factor may include at least one of the presence or absence of leakage, the size of the water droplets, the increase and decrease of the leakage amount, the leakage length and the leakage duration.

In addition, the humidity factor may include at least one of room humidity and a duration above a predetermined humidity, and the temperature factor may include room temperature.

Subsequently, steps S12, S22, and S32 are compared to sensed measured values and a predetermined reference value.

In this case, the preset reference value refers to a threshold value recognized by the leakage sensing unit, the humidity sensing unit, and the temperature sensing unit as a dangerous value. This reference value may be a fixed value or may be a variation value controlled to an appropriate value according to the surrounding environment.

In one embodiment, when the measured value of each sensing factor is above or below a predetermined reference value on each sensing unit, each sensing unit recognizes the measured value as a risk value.

In detail, in the case of the leak sensing unit and the humidity sensing unit, when the sensed measured value is greater than or equal to a predetermined reference value, the measured value is recognized as a risk value. In contrast, in the case of the temperature sensing unit, when the sensed measured value is equal to or less than a predetermined reference value, the measured value is recognized as a risk value.

However, this is merely an example, and as another embodiment, it is possible to make the measured value recognized as a dangerous value only when the sensed measured value is above or below a predetermined reference value.

Then, when the sensed measurement value is recognized as a dangerous value, steps S13, S23, and S33 are generated to generate a leak signal, a humidity signal, and a temperature signal.

On the other hand, when the measured value sensed in the previous steps (S12, S22, S32) does not reach the reference value and is not recognized as a risk value, the first step of sensing each sensing factor (S11, S21, S31) Will return to.

Subsequently, the integrated sensing information is generated by dividing the generated signal (generated signal) and the non-generated signal (non-generated signal) among the leakage signal, the humidity signal, and the temperature signal (S40).

This step may be performed by the microcontroller unit receiving sensing signals generated from each of the sensing units, and collecting information on which one of the sensing units generates a signal and which sensing unit does not generate a signal.

In an embodiment, the integrated sensing information may be generated by displaying the generated signal among the leakage signal, the humidity signal, and the temperature signal as “1” and the non-generated signal as “0”.

Thereafter, the risk state is determined as one of low risk, medium risk, and high risk based on the integrated sensing information (S50).

This step may be performed by the control server unit having received the integrated sensing information from the microcontroller to determine a dangerous state of the current situation.

In an embodiment, the critical signals may be selected in the order of the influence of the leakage signal, the humidity signal, and the temperature signal in the order of the greatest influence, so that the dangerous state may be determined by evaluating a high risk level when the important signals are generated signals.

Meanwhile, specific embodiments of the method of determining the critical state by selecting the critical signals as described above will be described later with reference to FIGS. 5 to 7.

After that, the output signal is generated according to a dangerous state determined as one of low risk, medium risk, and high risk (S51), S52, and S53.

This step may be performed by providing the output unit with an output signal according to the dangerous state determined by the control server unit.

Specifically, the control server unit selectively generates the low risk output signal, the medium risk output signal, and the high risk output signal according to the dangerous state determined by the control server unit.

Subsequently, a warning operation is performed in response to the output signal (S61), S62, and S63.

In this step, the output unit receives any one of a low risk output signal, a medium risk output signal, and a high risk output signal generated from the control server unit, and the output unit may perform a warning operation in response to the received output signal.

In one embodiment, the warning operation may be to transmit a notification message according to a dangerous state determined as one of low risk, medium risk and high risk. In this case, the notification message may be transmitted to the user terminal using a mobile communication network.

Specifically, when the output unit receives the low risk output signal, it may transmit a "caution" message, and when the output unit receives the medium risk output signal, it may transmit a "alarm" message, and the output unit receives the high risk output signal. In one case, you can send the "occurrence" message.

As a result, the user can efficiently cope with the current leakage situation through the risk-specific notification message transmitted to the user terminal.

5 to 7 are flowcharts schematically illustrating an example of a method for determining a danger state in a leak monitoring method according to an embodiment of the present invention.

First, referring to FIG. 5, the determining of the dangerous state shown in FIG. 4 (S50) may include the following detailed steps.

First of all, it is determined whether the leak signal is a generation signal (S101).

In this stage, if the leakage signal is a generated signal, the risk of leakage can be evaluated as a high risk, whereas if the leak signal is a non-generated signal, the flow returns to the initial stage of determining a dangerous state.

In this case, since the leak signal corresponds to an important signal having a great influence on the leak, when the leak signal is a generated signal, the leak risk may be highly evaluated. This means that a leak signal is generated based on the fact that the actual water or chemical liquid is in contact with the leak sensor, so that the liquid may be just before or after the liquid flows into various facilities, and whether the leak signal is generated is a dangerous condition. It can be an important criterion in judging the situation.

Subsequently, a high risk output signal is generated (S111) and a step (S121) of transmitting an "occurrence" message to a user terminal is sequentially performed.

Meanwhile, referring to FIG. 6, the determining of the dangerous state shown in FIG. 4 (S50) may include the following detailed steps.

First of all, it is determined whether the humidity signal is a generated signal (S201).

In this step, when the humidity signal is a generated signal, the process proceeds to a subsequent determination step (S202), and when the humidity signal is a non-generated signal, the process returns to the initial stage of determining a dangerous state.

In this case, the humidity signal may be an important signal having a great influence on the leakage, and thus, when the humidity signal is a generated signal, the risk of leakage may be highly evaluated. This means that the generation of humidity signal means that the indoor humidity is high, so that the high humidity increases the likelihood that condensation will occur in the future. It can be an important criterion.

Thereafter, when the humidity signal is a generation signal, a step (S202) is performed to determine whether the leakage signal is a generation signal.

At this stage, if the leak signal is a generated signal, the risk of leakage can be evaluated as high risk, whereas if the leak signal is a non-generated signal, the leak risk can be evaluated as a medium risk.

In this case, the leak signal is an important signal having a large influence on the leak, as described above, and whether the humidity signal is the generated signal or the non-generated signal, once the leak signal is the generated signal, the risk of leakage is high.

After that, when both the humidity signal and the leak signal are generated signals, a high risk output signal is generated (S211) and a step of transmitting a "occurrence" message to the user terminal (S221) is sequentially performed.

On the other hand, when the humidity signal is a generated signal or the leakage signal is a non-generated signal, the step of generating a medium-risk output signal (S212) and transmitting a "alarm" message to the user terminal (S222) sequentially.

In addition, referring to FIG. 7, the determining of the dangerous state (S50) illustrated in FIG. 4 may include the following detailed steps.

First of all, it is determined whether the temperature signal is a generated signal (S301).

In this step, if the temperature signal is a generated signal, the process proceeds to a subsequent determination step (S302). When the temperature signal is a non-generated signal, the process returns to the initial stage of determining a dangerous state.

The temperature signal is less important than the leak signal and the humidity signal generated by directly sensing the presence and content of moisture, but the temperature signal may also be evaluated as a signal that has an influence on the leak. This means that the generation of a temperature signal means that the room temperature is low, and therefore the low temperature may cause condensation in the future.

Thereafter, a step (S302) is performed to determine whether all signals except the temperature signal are non-generated signals. In other words, this step is a step of determining whether at least one of the leakage signal and the humidity signal is a generation signal in addition to the temperature signal.

At this stage, if all the signals except the temperature signal are non-generated signals, the risk of leakage can be assessed as low risk, whereas in addition to the temperature signal, the leak risk is mediated if at least one of the leak and humidity signals is a generated signal. It can be evaluated by more than hum.

This is because even if the temperature is perceived to be relatively low, it is unlikely to lead to moisture generation unless there is a significant change in the other sensing factors.

Then, when all signals except the temperature signal are non-generated signals, a low risk output signal is generated (S311) and a step of transmitting a "attention" message to a user terminal (S321) sequentially.

On the other hand, when at least one of the leakage signal and the humidity signal in addition to the temperature signal is a generation signal, generating a medium or high risk output signal (S312) and transmitting a "alarm" or "occurrence" message to the user terminal, etc. It passes through (S322) sequentially.

The leak monitoring method according to embodiments of the present invention may be implemented as computer readable codes on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored in a distributed fashion and executed by at least one process. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

As described above, according to one embodiment of the present invention, it is possible to improve the accuracy of the leak monitoring by determining the leak risk state step by step.

In addition, by performing a customized warning operation corresponding to each dangerous state, not only can efficiently cope with the current leakage situation, but also can store various sensing information in the control server and use it for future leakage preparation.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary and will be understood by those skilled in the art that various modifications and variations can be made therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
