The system and method for monitoring whether a fire extinguishing agent leaks from a fire extinguishing container according to the present invention is based on the fact that the cause of the pressure reduction of the fire extinguishing container may be caused by a fire extinguishing agent leak or a decrease in the temperature of the storage container chamber.

That is, when the pressure decrease occurs, the temperature of the storage chamber can be measured, and accordingly, it is possible to clearly determine whether the extinguishing agent leaks.

Hereinafter, a system and method for monitoring whether a fire extinguishing agent leaks in a fire extinguishing container according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the system 100 for monitoring whether a fire extinguishing agent leaks out of a fire extinguishing container according to the present invention may include a pressure monitoring unit 110, a temperature measuring unit 120, and a controller 130.

Specifically, the pressure monitoring unit 110 may monitor the pressure of each of the plurality of fire extinguishing containers disposed in the fire storage container. At this time, the pressure value of the fire extinguishing vessel itself or the degree of pressure reduction (different from the initial pressure value) of the fire extinguishing vessel, etc., it can be determined whether the pressure of the fire extinguishing vessel (information).

For example, the pressure monitoring unit 110 may be implemented as at least one pressure sensor that can monitor the pressure of the plurality of fire extinguishing containers, respectively. Accordingly, it is possible to detect a fire extinguishing vessel in which a pressure loss (pressure difference, pressure reduction degree) occurs 10% or more. As another example, a fire extinguishing container having a pressure equal to or less than a predetermined value may be detected.

The temperature measuring unit 120 may measure the temperature of the fire storage container based on the pressure of at least one fire container being reduced to a predetermined value or less.

In an embodiment, the temperature measuring unit 120 is at least one temperature sensor. The temperature measuring unit 120 may be disposed in a collection tube connected to a plurality of fire extinguishing containers in a storage container room.

In addition, the controller 130 may determine whether the at least one extinguishing agent leaks based on the measured temperature value of the extinguishing container storage chamber and the temperature value of the collection pipe connected to the plurality of extinguishing containers.

Accordingly, the text or sound informing whether the extinguishing agent leaks from the fire extinguishing container is output so that the administrator can check it.

Alternatively, a leakage notification message may be transmitted to the mobile terminal possessed by the administrator, or a specific sound / vibration notification may be output from the mobile terminal. To this end, a signal of a control command may be transmitted from the fire fighting container management system 100 to a mobile terminal possessed by an administrator.

Hereinafter, a specific embodiment of the system for monitoring the leakage of the extinguishing agent according to the present invention will be described.

In an embodiment, the controller 180 may reduce the pressure of at least one extinguisher vessel of the plurality of extinguisher vessels to a predetermined value or less, and the measured temperature value of the extinguisher vessel compartment is less than the preset first value. Based on the above, it is possible to output a notification informing that the temperature adjustment of the fire storage chamber.

In another embodiment, the temperature measuring unit 120 measures the temperature of the collection tube connected to the plurality of fire extinguishing vessels, and the controller 180 is a temperature of the collection tube is greater than or equal to a second predetermined value. And outputting a notification indicating that the at least one extinguishing agent of the at least one extinguishing container is leaked, and changing the extinguishing agent discharge path to the preset preliminary path based on the temperature of the collection pipe being less than the second predetermined value. have. In this case, the preset preliminary path may be defined as a change path (preliminary system path) that is set in advance for fire suppression.

In another embodiment, the controller 180 calculates an average pressure value of the plurality of fire extinguishing vessels based on the measured temperature value of the fire extinguishing vessel storage chamber lower than the preset first value, and the average value. If the pressure value is less than the third set value, it may output a notification informing that the temperature adjustment of the fire storage container storage is necessary.

Referring to FIG. 2, a plurality of fire extinguishing containers may be disposed in the fire extinguishing container storage chamber, and a pressure sensor 110 may be attached to each of the fire extinguishing containers.

In an embodiment, each of the pressure sensors 110 may measure the pressure of the fire extinguishing vessel in real time or at predetermined intervals.

In addition, the first temperature sensor 120-1 may be disposed in the protection zone, and the second temperature sensor 120-2 may be disposed in a collection pipe connected to the plurality of fire extinguishing containers.

Hereinafter, specific embodiments of the present invention will be described with reference to FIG. 2.

In the first pressure sensor 110 for monitoring the pressure of the first fire extinguishing vessel, when it is detected that the pressure of the first fire extinguishing vessel falls below a predetermined value, the first temperature sensor 120-1 disposed inside the protection zone. ), It is possible to measure the temperature of the fire storage chamber (inside).

At this time, the temperature of the fire container storage chamber can be detected more than the first predetermined value.

Accordingly, the temperature of the collecting tube can be measured by the second temperature sensor 120-2 arranged in the collecting tube. As a result, when the temperature of the fire extinguishing vessel storage room is greater than or equal to the first predetermined value, and the temperature of the collecting pipe is also greater than the second predetermined value, it is determined that the extinguishing agent has leaked from the first fire extinguishing container may be notified. have.

For example, whether the leakage of the extinguishing agent is output on the display of the extinguishing container management system 100 or a specific sound may be output through the speaker. Alternatively, a message, sound, vibration, or the like indicating whether the extinguishing agent is leaked to the terminal possessed by the administrator may be output.

As another example, when the temperature of the fire extinguishing vessel storage room is greater than or equal to the first predetermined value and the temperature of the collecting tube is less than the second predetermined value, it is determined that the extinguishing agent of the main storage container is released, and the extinguishing agent stored in the preliminary storage container. Can be released.

That is, by additionally considering the temperature of the collecting pipe, the preliminary fire protection system is executed secondarily, so that an effective fire suppression can be achieved.

If it is detected that the pressure of the first fire extinguishing vessel falls below a predetermined value, the first temperature of the fire extinguishing vessel storage chamber (inside) is set by the first temperature sensor 120-1 disposed inside the protection zone. When measured below, the pressure reduction of the first fire extinguishing vessel may be determined by the temperature decrease of the fire extinguishing vessel storage chamber, not the leakage of the extinguishing agent. Accordingly, it is possible to output a notification to adjust the internal temperature of the storage chamber.

As another example, it is detected that the pressure of the first fire extinguishing vessel drops below a predetermined value, and the temperature of the fire extinguishing vessel storage chamber (inner) is set by the first temperature sensor 120-1 disposed inside the protection zone. When measured below one value, the average pressure value of the plurality of fire extinguishing containers can be calculated.

Thereafter, when the average pressure value is less than the third value, the notification may be output to adjust the internal temperature of the storage chamber. On the other hand, when the average pressure value is greater than or equal to the predetermined third value, the pressure of the fire extinguishing vessel is monitored again. That is, it is detected that the pressure of the first fire extinguishing vessel falls below a predetermined value, and the first temperature of the fire extinguishing vessel storage chamber (inside) is set by the first temperature sensor 120-1 disposed inside the protection zone. If measured below, the average pressure value of the plurality of fire fighting vessels may be further considered.

Referring to FIG. 3, a step S310 of monitoring the pressure of each of the plurality of fire extinguishing containers disposed in the fire extinguishing container storage chamber is performed.

Subsequently, based on the pressure of the at least one extinguisher vessel of the plurality of extinguishers being lowered below a predetermined value, the step S320 of measuring the temperature of the extinguishing vessel storage chamber is performed.

Next, based on the measured temperature value of the fire extinguishing container storage chamber and the temperature value of the collection pipe connected to the plurality of fire extinguishing containers, determining whether the at least one extinguishing agent leaks of the extinguishing agent is performed (S330). .

Hereinafter, a specific embodiment of the method for monitoring the leakage of the extinguishing agent according to the present invention will be described.

In an embodiment, the step S330 may include outputting a notification indicating that the temperature adjustment of the fire storage container is necessary based on the measured temperature value of the fire storage container being less than a first predetermined value. Can be.

In another embodiment, the step S330, by measuring the temperature of the collecting tube connected to the plurality of fire extinguishing vessel, based on the temperature of the collecting tube is a predetermined second value or more, extinguishing the at least one fire extinguishing vessel Outputting a notification informing that the medicine is leaking, and changing the extinguishing agent discharge path to a predetermined preliminary system path for extinguishing the fire based on the temperature of the collection pipe lower than the second predetermined value. have.

In another embodiment, the step S330, based on the measured temperature value of the fire container storage chamber is less than the predetermined first value, calculates the average pressure value of the plurality of fire container, and the average pressure value If it is less than the third set value, the method may further include outputting a notification informing that the temperature adjustment of the storage chamber of the fire extinguishing vessel is required.

Referring to Figure 4, first, the step (S410) of monitoring the pressure of the plurality of fire extinguishing vessel is in progress.

To this end, a pressure sensor may be disposed in each of the plurality of fire extinguishing containers. In addition, the monitoring cycle may be performed to monitor the pressure of the fire extinguishing vessel in real time or at predetermined intervals.

Subsequently, a step (S420) of determining whether the pressure of the fire extinguisher vessel in which the pressure decrease is detected is less than or equal to the preset value P1 is performed.

If it is not reduced to less than P1, step S410 of monitoring the pressure of the fire extinguishing container proceeds again. On the other hand, if it is reduced to less than P1, step S430 is determined by measuring the internal temperature.

In detail, step S430 of determining whether the internal temperature is equal to or greater than a predetermined value T1 is performed.

Accordingly, when the internal temperature is greater than or equal to the preset value T1, a step (S440) of determining whether or not the temperature of the collection pipe is greater than or equal to the preset value T2 is performed.

On the other hand, if the internal temperature is not more than the predetermined value T1, calculating the pressure average value of the extinguishing vessels in the storage chamber, and determining whether the pressure average value is less than the predetermined value P2 (S470) is performed.

If the pressure average value is less than the predetermined value P2, it is determined that the cause of pressure loss of the fire extinguishing vessel is due to the decrease in the internal temperature. Accordingly, step S480 of informing that the temperature adjustment is necessary is performed.

On the other hand, if the pressure average value is not less than the predetermined value P2, the step (S410) of monitoring the fire vessel pressure again proceeds.

In step S440 again, if it is determined that the temperature of the collecting tube is equal to or greater than the predetermined value T2, the step S450 of informing the leakage of the fire extinguishing container is performed.

On the other hand, if it is determined that the temperature of the collecting pipe is not more than the predetermined value T2, the step of switching to the preliminary system (S460) is performed.

That is, it is possible to determine whether the discharge for fire suppression or a simple leakage according to the temperature of the collection pipe, and to switch to a preliminary system in case of fire suppression.

Each of the preset pressure and temperature values P1, P2, T1, and T2 may be experimentally calculated. In addition, it may be calculated differently by the fire extinguishing container, internal storage room, and other factors.
