Embodiments for Carrying Out the Invention

[0014] [Configuration of Fire Fighting Equipment] Triggered by a sudden drop in the pressure of the sensing tube, the container valve opens and the fire extinguishing agent is released. For cable tray fire extinguishing, the sensing tube in the tray melts and ruptures due to the heat of the flame, resulting in a pressure drop. For power panel and control panel fire extinguishing, the detection of smoke generation at the protected object opens the solenoid valve, reducing the pressure of the sensing tube.

[0015] [Maintenance and Management of Fire Fighting Equipment] Due to the material and structure of the sensing tube, the pressure gradually decreases.

[0016] When the pressure of the sensing tube gradually decreases and falls below a predetermined value, nitrogen is replenished from the container side. If replenishment from the container continues, the container pressure will eventually drop to its limit, making it impossible to release the fire extinguishing agent.

[0017] When nitrogen is replenished from the container, the fire extinguishing agent also leaks out at the same time, so it is necessary to manage the amount of fire extinguishing agent.

[0018] Therefore, periodic inspections of the detection tube pressure, fire extinguishing agent volume, and container pressure, as well as pressurization of the detection tube, are necessary. Depending on the situation, container replacement may be required.

[0019] If the sensing tube pressure falls below the lower limit during inspection, re-pressurize it to the upper limit.

[0020] [Inspection Workflow] This is an excerpt containing only information related to sensing tube pressure, container pressure, and fire extinguishing agent volume.

[0021] [Preparation for inspection] Launch the management software installed on a tablet or other device and read the two-dimensional code (registration information) attached to the container to be inspected. The two-dimensional code may be replaced with a barcode.

[0022] Alternatively, you can directly enter the container symbol and number stamped on the container to be inspected in the container number field.

[0023] Verify that the information to be inspected is displayed in the fire extinguishing agent storage container information section and the detection tube information section.

[0024] Verify that the previous measurement values ​​are displayed in the current measurement value column (4 locations). [Fire extinguishing agent quantity check] For fire extinguishing agents stored in liquid form, the liquid level is determined using a liquid level gauge or similar device, and the height from the bottom of the container to the liquid level is measured using a scale.

[0025] The container temperature is measured using a surface thermometer. Enter the measured liquid level height and temperature values ​​into the measurement values ​​field in the management software.

[0026] The fire extinguishing agent quantity calculation results section displays the amount of fire extinguishing agent, related information, and inspection results. At the same time, the color of the container icon changes.

[0027] [Container pressure check] A pressure gauge is attached to the joint of the fire extinguishing agent storage container to measure the container pressure.

[0028] Enter the measured container pressure value into the measurement value field in the management software. The storage container internal pressure calculation results section displays the pressure value, related information, and inspection results.

[0029] [Check the pressure of the sensing tube] A pressure gauge is attached to the fitting of the sensing tube, and the pressure in the sensing tube is measured.

[0030] Enter the measured pressure value of the sensing tube into the measurement value field in the management software. The pressure value, related information, and inspection results are displayed in the sensing tube calculation results section.

[0031] [After inspection] Save the input data from the management software.

[0032] If the sensing tube pressure falls below the lower control limit, the sensing tube will be pressurized to the upper control limit.

[0033] Enter the data after pressurization into the management software and save it. [Features of the management software] By scanning a QR code or entering the container number, information about the container and sensing tube will be displayed.

[0034] Information from the previous inspection will be displayed. (Only before input. The display will disappear after input.) The amount of fire extinguishing agent (at 20°C) is calculated from the liquid level and temperature.

[0035] This allows you to check the comparison with the previous fill and the fill volume ratio. You can determine whether it passed or failed. You can also check this by the color of the container icon.

[0036] The container pressure is also automatically calculated based on a 20°C conversion. Based on trends from past inspection results and the current results, the estimated time until loss of function or the estimated time until the control limit is exceeded is displayed.

[0037] Trends can also be displayed and checked using graphs. The temporary save function allows you to save values ​​during measurement. For example, you can measure the liquid level of multiple containers at once, then measure the container pressure at once, then measure the sensing tubes at once, and so on. This makes the work smoother.

[0038] The measured values ​​can be printed on a record sheet. The embodiments will be described below with reference to the drawings. The same or corresponding parts will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0039] Figure 1 is a schematic diagram of a cable tray fire extinguishing system 60 according to Embodiment 1. As shown in Figure 1, in the cable tray fire extinguishing system 60 according to Embodiment 1, a container valve is attached to the top of the fire extinguishing agent storage container 1. The fire extinguishing agent storage container 1 is supported by a container support body 15.

[0040] The container valve 19 is connected to a copper pipe 25 for fire extinguishing agent discharge, a sensing tube 24, a pressure switch 4 for the sensing tube, and a pressure switch 3 for the storage container. The pressure switch 4 for the sensing tube is not limited to being directly connected to the container valve 19, but may also be connected along the sensing tube 24 (for example, near the pressure gauge). Note that the pressure switch 4 for the sensing tube and the pressure switch 3 for the storage container may not be connected.

[0041] The sensing tube 24 is kept under constant pressure. Cable trays 31 are installed in factories, buildings, power plants, etc. Cable trays 31 are cylindrical and contain cables. Cable trays 31 are covered with flame-retardant sheets 32. The flame-retardant sheets 32 are secured to the cable trays 31 by fixing bands 33. Stainless steel bands are wrapped around the cable trays 31 in the same position as the fixing bands 33 to prevent the flame-retardant sheets 32 from sagging into the cable tray.

[0042] A sensing tube 24 is provided inside the cable tray 31. The sensing tube 24 may or may not be in contact with the cable. A copper pipe 25 for discharging fire extinguishing agent is provided inside the cable tray 31. A spray nozzle 34 for discharging fire extinguishing agent is attached to the copper pipe 25. A flexible tube 2 is interposed between the container valve 19 and the copper pipe 25 for discharging fire extinguishing agent. A terminal block 22 is provided in the terminal box 21. A pressure gauge 23 is provided in the terminal box 21.

[0043] The fire extinguishing agent storage container 1 contains, for example, a halogenated fire extinguishing agent, FK-5-1-12. This agent is pressurized by nitrogen inside the fire extinguishing agent storage container 1. This nitrogen is supplied to the sensing tube 24 via the pressure switch 4 for the sensing tube. When supplying nitrogen into the sensing tube 24 during installation, if nitrogen is added from the fire extinguishing agent storage container 1, the amount of nitrogen inside the fire extinguishing agent storage container 1 will decrease. Therefore, nitrogen may be added to the sensing tube 24 from outside the fire extinguishing agent storage container 1.

[0044] When the heat of the fire melts the sensing tube 24, the pressure inside the sensing tube 24 decreases.

[0045] When the pressure inside the sensing tube 24 decreases, the container valve 19 is activated, and the fire extinguishing agent (FK-5-1-12) is released from the fire extinguishing agent discharge nozzle 34 inside the cable tray 31 through the fire extinguishing agent discharge copper pipe 25.

[0046] When the pressure inside the sensing tube 24 decreases, the pressure switch 4 for the sensing tube is activated, and an alarm signal is emitted.

[0047] When the pressure inside the fire extinguishing agent storage container 1 decreases, the storage container pressure switch 3 is activated and an alarm signal is issued.

[0048] Figure 2 is a schematic diagram of a fire extinguishing system according to Embodiment 2. As shown in Figure 2, the fire extinguishing device package 100 releases fire extinguishing agent gas to the power panel or control panel 135.

[0049] The fire extinguishing system package includes fire extinguishing agent storage containers 101 and 107. These containers contain, for example, a halogenated fire extinguishing agent, FK-5-1-12. This agent is pressurized by nitrogen within the fire extinguishing agent storage containers 101 and 107.

[0050] A container valve 119 is attached to the fire extinguishing agent storage container 101. A container valve 129 is attached to the fire extinguishing agent storage container 107. Container valves 119 and 129 are connected to a sensing tube 124.

[0051] The sensing tube 24 is kept under constant pressure. When the pressure inside the sensing tube 124 drops, the fire extinguishing agent gas in the fire extinguishing agent storage containers 101 and 107 is released from the container valves 119 and 129.

[0052] The container valves 119 and 129 are connected to the internal piping 142 of the package. The fire extinguishing system package includes a solenoid valve 141 and a highly sensitive smoke detector 138.

[0053] The power supply panel or control panel 135, which is the target of fire extinguishing, functions as the power supply panel or control panel of the equipment. The target of fire extinguishing is not limited to the power supply panel or control panel 135, but any item that has the potential to cause a fire.

[0054] A fire extinguishing agent discharge nozzle 134 is provided on the power panel or control panel 135. The fire extinguishing agent discharge nozzle 134 is connected to a fire extinguishing agent discharge copper pipe 125. The fire extinguishing agent discharge copper pipe 125 is connected to the internal piping 142 of the package by a fitting 143.

[0055] A suction port 137 of the suction piping 136 is provided in the power panel or control panel 135. The suction port 137 uses negative pressure to draw air from inside the power panel or control panel 135 and send it to the ultra-high sensitivity smoke detector 138.

[0056] When a fire occurs in the power panel or control panel 135, smoke is generated inside the power panel or control panel 135. The smoke is sent to the ultra-high sensitivity smoke detector 138 via the suction port 137 and suction piping 136. When the ultra-high sensitivity smoke detector 138 detects smoke, the solenoid valve 141 opens. This causes a decrease in the pressure inside the sensing tube 124 connected to the solenoid valve 141. Because the pressure inside the sensing tube 124 decreases, fire extinguishing agent gas is supplied from the container valves 119 and 129 to the internal piping 142 of the package. The fire extinguishing agent gas is released into the power panel or control panel 135 from the fire extinguishing agent discharge nozzle 134 via the fire extinguishing agent discharge copper pipe 125.

[0057] The inspection method for these fire extinguishing agent storage containers 1,101 and 107 will be described below. (1) Inspection method for fire extinguishing agent storage containers 1,101,107 (1-1) Method for checking the amount of fire extinguishing agent (liquid level) Using a liquid level meter or similar device, the liquid level of the fire extinguishing agent sealed in the fire extinguishing agent storage containers 1,101,107 is measured, and the surface temperature of the fire extinguishing agent storage containers is measured using a surface thermometer or similar device. The measurement results are then entered into the management system.

[0058] (1-2) Method for checking the internal pressure of fire extinguishing agent storage containers The internal pressure of the fire extinguishing agent storage containers 1,101 and 107 is measured using a pressure gauge. The measured pressure is then entered into the management system.

[0059] This document explains how to inspect the sensing tubes 24 and 124. (2) Inspection method for sensing tubes 24 and 124 Method for checking the internal pressure of sensing tubes 24 and 124 The internal pressure of sensing tubes 24 and 124 is measured using a pressure gauge. The measured pressure is then entered into the management system.

[0060] (3) Recording of measurement data (3-1) The measurement results of the amount of fire extinguishing agent, the internal pressure of the storage container, and the internal pressure of the sensing tube are recorded using a management system (management software installed on a tablet or other device).

[0061] Figure 3 shows an example of the management system's display screen. (3-2) Read the two-dimensional code attached to the fire extinguishing system package to be measured, or manually enter the numbers of the fire extinguishing agent storage containers 1,101 and 107 to display information about the fire extinguishing agent storage containers 1,101 and 107. Enter the "liquid level," "pressure," and "temperature" of the fire extinguishing agent storage containers 1,101 and 107 measured during the inspection, as well as the "pressure" of the sensing tube, to display a pass / fail judgment and related information. Enter the identifier of the fire extinguishing agent storage container and the amount of fire extinguishing agent in the fire extinguishing agent storage container or information regarding the amount of fire extinguishing agent in the fire extinguishing agent storage container to display the rate of decrease of fire extinguishing agent in the fire extinguishing agent storage container since filling. Entering the identifier of the fire extinguishing agent storage container and the amount of fire extinguishing agent in the fire extinguishing agent storage container or information regarding the amount of fire extinguishing agent in the fire extinguishing agent storage container may also display the rate of decrease of fire extinguishing agent in the fire extinguishing agent storage container since the last time.

[0062] (3-3) The operating procedures for the management system are shown in Table 1.

[0063] [Table 1]

[0064] (4) Maintenance and management of fire extinguishing equipment To maintain this fire extinguishing system (cable tray fire extinguishing system 60, fire extinguishing device package 100) in good condition over the long term, in addition to regular inspections, the lifespan and degree of deterioration will be predicted based on the inspection results, and the equipment will be replaced in a planned manner. This fire extinguishing system contains equipment with a risk of leakage, such as "fire extinguishing agent storage containers filled with high pressure" and "sensing tubes that are constantly under pressure," and if proper maintenance is not carried out, it may not be possible to effectively release the fire extinguishing agent in the event of an emergency.

[0065] By conducting the periodic inspections described in sections (1) and (2), it becomes possible to detect and repair equipment malfunctions caused by leaks. Furthermore, it becomes possible to predict the time it will take from the current state to complete loss of function and to take preventative measures. The following describes methods for addressing leak risks.

[0066] (4-1) Measures to mitigate the risk of leakage from fire extinguishing agent storage containers For fire extinguishing agent storage containers, the amount of fire extinguishing agent and the internal pressure of the fire extinguishing agent storage containers will be checked and managed accordingly.

[0067] Figure 4 shows the predicted curve regarding the maintenance of functionality. As shown in Figure 4, when the results of this inspection are entered into the management system described in section (3) "Recording Measurement Data," the predicted period (A) until functionality can no longer be maintained, assuming the current trend continues based on the results of the previous inspection, will be displayed. To prevent loss of functionality, planned replacements, etc., based on that period will be necessary.

[0068] By inputting the results measured during inspection into the management system, a pass / fail judgment and related information are displayed.

[0069] Figure 5 shows a screen displaying the estimated period until the management system loses functionality. The "estimated period until loss of functionality" in Figure 5 is displayed based on the estimated curve (dashed line in Figure 4) calculated from the results of the previous and current inspections. Therefore, it is not displayed during the first inspection, but is displayed from the second inspection onward. Also, the error in the estimated curve will be large when the number of measurement results is small, but the accuracy will improve as the number of samples increases. Table 2 shows an example of a guideline for equipment replacement planning based on the estimated period.

[0070] [Table 2]

[0071] By referring to the displayed forecast period and the example equipment replacement plan in Table 2, it becomes possible to formulate a replacement plan that prevents the loss of functionality while the equipment is still functional.

[0072] (4-2) Measures to mitigate leakage risk of sensing tubes This fire extinguishing system has a function to prevent fire (temperature) monitoring from becoming impossible due to a decrease in the internal pressure of the sensing tubes 24 and 124. When the internal pressure of the sensing tubes 24 and 124 falls below a certain value, nitrogen gas from the fire extinguishing agent storage containers 1,101 and 107 is supplied to the sensing tubes 24 and 124, thereby maintaining the internal pressure of the sensing tubes 24 and 124 above a certain value.

[0073] It is necessary to reliably carry out the above-mentioned periodic inspections and to monitor the equipment's condition through the management system in order to prevent loss of function due to leakage from sensing tubes 24 and 124.

[0074] If the internal pressure of the sensing tubes 24 and 124 continues to decrease and falls below a predetermined value, it is possible that the pressure inside the fire extinguishing agent storage containers 1, 101 and 107 is decreasing.

[0075] The management system will check the amount of fire extinguishing agent and the internal pressure of fire extinguishing agent storage containers 1,101 and 107. If they are below the specified value, fire extinguishing agent storage containers 1,101 and 107 will be replaced or refilled. Even if they are not below the specified value, if the expected period until loss of function is short, a plan will be made to replace or refill fire extinguishing agent storage containers 1,101 and 107.

[0076] If the internal pressure of the sensing tubes 24 and 124 consistently falls below the control limit during each inspection, it is possible that there is continuous leakage from the joints or other parts of the sensing tubes 24 and 124.

[0077] In this case, for example, an inspection is conducted using an ultraviolet absorption multi-gas sensor and laser light to detect trace amounts of fire extinguishing agent leaking from the sensing tubes 24 and 124, thereby identifying the leak location and replacing the sensing tube fittings, etc.

[0078] Figure 6 shows an excerpt of the management system screen. As shown in Figure 6, when the internal pressure value of the sensing tube is entered into the management system, the estimated period until nitrogen gas supply from the fire extinguishing agent storage container 1,101 begins is displayed. In addition, if there is a pressure drop, the amount of leakage and the pressure value obtained by converting the amount of leakage to the internal pressure of the container can also be displayed. Based on these values, the estimated timing for repressurizing the sensing tubes 24 and 124 and the replacement or refilling of the fire extinguishing agent storage containers 1,101 and 107 are planned.

[0079] In other words, by entering the identifier of the fire extinguishing agent storage container and the internal pressure of the fire extinguishing agent storage container, the estimated period until the fire extinguishing function is lost or the estimated period until it falls below the control lower limit is displayed (Figure 3, "Storage Container Internal Pressure Calculation Results").

[0080] Furthermore, by entering the identifier of the fire extinguishing agent storage container and the amount of fire extinguishing agent in the storage container or information regarding the amount of fire extinguishing agent, the estimated period until the fire extinguishing function is lost or the estimated period until it falls below the control lower limit will be displayed (Figure 3, "Fire Extinguishing Agent Amount Calculation Results").

[0081] By inputting the identifier of the fire extinguishing agent storage container and the internal pressure of the sensing tube connected to the fire extinguishing agent storage container, the estimated period until the fire extinguishing function is lost or the estimated period until the pressure falls below the control limit is displayed (Figure 3, "Sensing Tube Calculation Results").

[0082] In this embodiment, the expected period until loss of function is displayed, but it is not limited to this, and the expected period until the level falls below the control limit may also be displayed. When the level falls below the control limit, nitrogen gas is supplied from the fire extinguishing agent storage containers 1,101 and 107 to the sensing tubes 24 and 124. The expected period until the level falls below the control limit can be calculated by predicting the rate of decrease so far and regressing the decrease curve (straight line).

[0083] (5) About the management system The measurement results for the amount of fire extinguishing agent, the internal pressure of fire extinguishing agent storage containers 1,101 and 107, and the internal pressure of sensing tubes 24 and 124 are recorded by a management system (management software installed on a tablet or other device), and pass / fail is determined based on the calculated inspection results.

[0084] (5-1) Explanation of the Management System Display Screen Figure 7 is a diagram illustrating the display screen of the management system. Table 3 is a table showing each item in the management system.

[0085] [Table 3]

[0086] (5-2) How to operate the management system (5-2-1) Starting the management system Start the management system on the tablet or other device.

[0087] Figure 8 shows the initial screen of the management system. (5-2-2) Container information loading Figure 9 shows the screen after reading the information of fire extinguishing agent storage containers 1,101 and 107. Press the QR code reading key to activate the camera and read the QR codes attached to the fire extinguishing agent storage containers 1,101 and 107. After reading the QR codes, the information of fire extinguishing agent storage containers 1,101 and 107 and the information of sensing tubes 24 and 124 will be displayed.

[0088] For subsequent measurements, the previous measurement value will be displayed in the cell corresponding to the current measurement value (fire extinguishing agent storage container 1,101,107; sensing tube 24,124). (Entering a new value will erase the display of the previous measurement value.) Figure 10 shows the screen after entering the numbers for fire extinguishing agent storage containers 1,101 and 107. If you cannot read the QR code, click the fire extinguishing agent storage container number cell and enter the container number engraved on the fire extinguishing agent storage container using the numeric keypad. (Press Enter to update the cell.) Once you enter the container number, the fire extinguishing agent storage container information, sensing tube information, and the previous measurement value will be displayed.

[0089] (5-2-3) Liquid level input / Temperature input Figure 11 shows the screen after inputting the liquid level and temperature. Measure the liquid level of fire extinguishing agent storage containers 1,101 and 107, and enter the measurement results into the input cells. See "(1-1) Method for checking the amount of fire extinguishing agent (liquid level)".

[0090] When measurement results are entered, the fire extinguishing agent quantity determination, the fire extinguishing agent quantity calculation result, and the pass / fail status of the inspection result are displayed. Pressing the detailed display key displays a pop-up showing the ratio with the previous measurement value. In other words, the fire extinguishing agent is sealed in liquid in the fire extinguishing agent storage container, and when information on the liquid level position of the fire extinguishing agent is entered (see "Enter Measurement Results" in Figure 11), the amount of fire extinguishing agent lost from the previous measurement in the fire extinguishing agent storage container is displayed (see "Display 'Ratio to Previous Value' Pop-up" in Figure 11).

[0091] (5-2-4) Internal pressure of the container Figure 12 shows the screen after inputting the internal pressure of the container. Measure the pressure and surface temperature of the fire extinguishing agent storage container 1,101, and enter the measurement results into the input cells. See "(1-2) Method for checking the internal pressure of the fire extinguishing agent storage container". Once the measurement results are entered, the calculated internal pressure of the storage container and whether the inspection result is pass or fail will be displayed.

[0092] (5-2-5) Input pressure inside the sensing tube Figure 13 shows the screen after inputting the internal pressure of sensing tubes 24 and 124. Measure the internal pressure of sensing tubes 24 and 124 and enter the measurement result into the input cell. See "(2-2) Method for checking the internal pressure of sensing tubes 24 and 124".

[0093] After entering the measurement results, the storage container internal pressure calculation result and the pass / fail status of the inspection result will be displayed. Pressing the detailed display key will pop up a display showing the amount of leakage since the last inspection and the value of the leakage amount converted to internal container pressure.

[0094] In other words, by inputting the internal pressure of the sensing tube connected to the fire extinguishing agent storage container, the amount of leakage since the last inspection is displayed (Figure 13, "Amount of leakage since last inspection").

[0095] Furthermore, by inputting the internal pressure of the sensing tube connected to the fire extinguishing agent storage container, the system displays the amount of leakage since the last inspection, converted to the reduced internal pressure of the container (Figure 13, "Value converted from leakage amount to internal pressure of container").

[0096] (5-2-6) Data saving Figure 14 shows the screen when saving data. Once all measurement values ​​have been entered, press the Save Inspection Results key to save the data. Press "OK" when the "Save?" pop-up appears, and if the data is saved successfully, a "Saved." pop-up will appear.

[0097] (5-2-7) Other functions Figure 15 shows the screen when data is temporarily saved. Pressing the temporary save key allows you to temporarily save the information you are currently entering. This makes it possible to inspect multiple fire extinguishing agent storage containers 1,101,107 in parallel. The data for the temporarily saved containers can be retrieved by scanning the QR code or entering the container number, and the system will return to the state it was in when it was temporarily saved.

[0098] Figure 16 shows the memo field screen. When you press the memo key, the memo field pops up.

[0099] Figure 17 is a block diagram showing the configuration of the management system 500. The management system 500 includes an input unit 510, a calculation unit 520, a storage unit 530, and a display unit 540. Information regarding the fire extinguishing agent storage containers 1,101,107 and the sensing tubes 24,124 is input to the input unit 510. Information may be input to the input unit 510 by a camera or manually by a user. The input unit 510 is the part into which information is input, and the input method is not limited to input by an operator; information may be input wirelessly or wired. In the case of wireless communication, WiFi® (IEEE 802.11 family standard, or other mobile communication technology or a combination thereof) can be used. Furthermore, in the case of wired communication, for example, Ethernet® can be used.

[0100] The input unit 510 may communicate information via a gateway (GW) or without using a GW. The input unit 510 may also temporarily collect information regarding the amount of fire extinguishing agent and / or pressure in the fire extinguishing agent storage containers 1,101,107 when a disaster occurs (e.g., earthquake, tsunami, typhoon, war, riot, etc.). This is because the likelihood of a fire occurring increases in these cases, and the operation of the fire extinguishing agent storage containers 1,101,107 is checked before a fire breaks out. For natural disasters such as earthquakes, tsunamis, and typhoons, it is possible to determine whether a natural disaster has occurred by obtaining information from the Japan Meteorological Agency.

[0101] Furthermore, the input unit 510 may also contain information regarding location. If it contains information about the location of the fire extinguishing agent storage containers 1,101 and 107, the fire extinguishing agent storage containers 1,101 and 107 can be identified based on that location information. Alternatively, location information may be acquired using GPS (Global Positioning System). This makes it possible to acquire location information and information on the amount and / or pressure of the fire extinguishing agent in the fire extinguishing agent storage containers 1,101 and 107 and link them together.

[0102] The memory unit 530 can store the previous input data and the pass / fail judgment data. The memory unit 530 may also temporarily store the data currently being input.

[0103] The calculation unit 520 uses the input data and past data to calculate the period until functional loss, the pass / fail determination of the inspection results, and so on.

[0104] The display unit 540 displays a screen as shown in Figures 8 to 16, which includes the results calculated by the calculation unit 520.

[0105] The display unit 540 may also include an output unit that outputs the contents of the screen displayed on it in a predetermined report format.

[0106] (Note 1) A fire extinguishing equipment management system that, upon inputting an identifier for a fire extinguishing agent storage container and information regarding the amount of fire extinguishing agent in the fire extinguishing agent storage container, displays at least one of the following in the fire extinguishing agent storage container: (1) the amount or percentage of decrease in fire extinguishing agent since filling, and (2) the amount or percentage of decrease in fire extinguishing agent since the last time.

[0107] (Note 2) A fire extinguishing system management system that, upon input of the identifier of the fire extinguishing agent storage container and the internal pressure of the fire extinguishing agent storage container, displays the estimated period until the fire extinguishing function is lost or the estimated period until it falls below the control lower limit.
