[0014] [Fire extinguishing equipment configuration] A sudden drop in sensing tube pressure triggers the opening of the container valve and the release of fire extinguishing agent. In cable tray fire extinguishing, the sensing tube inside the tray melts and bursts due to the heat of the flame, causing a drop in pressure. In power panel and control panel fire extinguishing, smoke generation in the protected object is detected, opening the solenoid valve and reducing the sensing tube pressure.

[0015] [Fire extinguishing equipment maintenance] Due to the material and structure of the sensing tube, the pressure will gradually decrease.

[0016] The pressure in the sensing tube gradually decreases, and when it falls below a predetermined value, nitrogen is replenished from the container side. If refilling from the container continues, the container pressure will eventually drop to the point where it will no longer be able to release the extinguishing agent.

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

[0018] Therefore, periodic inspections of the sensing tube pressure, the amount of fire extinguishing agent, and the container pressure, as well as pressurization of the sensing tube, are required. Depending on the situation, the container may need to be replaced.

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

[0020] [Inspection work flow] This is an excerpt of only the information regarding sensing tube pressure, container pressure, and amount of extinguishing agent.

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

[0022] Alternatively, you can directly enter the container code and number engraved on the container to be inspected in the Container No. field.

[0023] Check that the information about the object to be inspected is displayed in the fire extinguishing agent storage container information column and the detection tube information column.

[0024] Check that the previous measurement value is displayed in the current measurement value field (4 places). [Fire extinguishing agent amount check] For fire extinguishing agents stored as liquids, the liquid level is identified 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 and temperature values into the measurement value field in the management software.

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

[0027] [Container pressure inspection] 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 pressure value, related information, and inspection results are displayed in the storage container internal pressure calculation result column.

[0029] [Sensing tube pressure check] A pressure gauge is attached to the joint of the sensing tube to measure the sensing tube pressure.

[0030] Enter the measured sensing tube pressure value 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 column.

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

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

[0033] Enter the post-pressurization data into the management software and save it. [Features of management software] By reading the two-dimensional code or entering the container number, information about the container and sensing tube is displayed.

[0034] Information from the previous inspection is displayed. (Only before input. After input, the display disappears.) The amount of extinguishing agent (calculated at 20°C) is calculated from the liquid level and temperature.

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

[0036] The container pressure is also automatically calculated as a 20°C equivalent value. Based on the trends of past inspection results and the current results, the expected period until function is lost or until the lower control limit is exceeded is displayed.

[0037] Trends can also be displayed and confirmed in graphs. The temporary saving function allows you to save values during measurement. For example, after measuring the liquid level of multiple containers at once, you can measure the container pressures at once and measure the sensing tubes at once. This makes the process smoother.

[0038] The measured values can be output to a record sheet. Hereinafter, embodiments will be described with reference to the drawings. The same or corresponding parts will be designated by the same reference characters, and description thereof will not be repeated.

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

[0040] Connected to the container valve 19 are a copper pipe 25 for discharging the fire extinguishing agent, a sensing tube 24, a sensing tube pressure switch 4, and a storage container pressure switch 3. The sensing tube pressure switch 4 does not necessarily have to be connected directly to the container valve 19, but may be connected somewhere along the sensing tube 24 (for example, near the pressure gauge). Note that the sensing tube pressure switch 4 and the storage container pressure switch 3 do not necessarily have to be connected.

[0041] The inside of the sensing tube 24 is constantly pressurized. A cable tray 31 is installed in a factory, building, power plant, etc. The cable tray 31 is cylindrical and has a cable installed inside it. The cable tray 31 is covered with a flame-retardant sheet 32. The flame-retardant sheet 32 is fixed to the cable tray 31 with a fixing band 33. A stainless steel band is wrapped around the cable tray 31 in the same position as the fixing band 33 to prevent the flame-retardant sheet 32 from sagging into the cable tray.

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

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

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

[0046] When the pressure inside the sensing tube 24 drops, the sensing tube pressure switch 4 is activated and a signal is transmitted.

[0047] When the pressure inside the fire extinguishing agent storage container 1 drops, the storage container pressure switch 3 is activated and a signal is sent out.

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

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

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

[0051] The inside of the sensing tube 24 is always pressurized. When the pressure inside the sensing tube 124 drops, the extinguishing agent gas inside the extinguishant storage containers 101, 107 is released from the container valves 119, 129.

[0052] The container valves 119 and 129 are connected to an internal package piping 142. The fire extinguishing device package includes a solenoid valve 141 and an ultra-sensitive smoke detector 138.

[0053] The power panel or control panel 135 as the fire extinguishing target acts as a power panel or control panel for the equipment. The fire extinguishing target is not limited to the power panel or control panel 135, and may be anything that has the potential to cause a fire.

[0054] A fire extinguishing agent discharge jet nozzle 134 is provided on the power supply panel or control panel 135. The fire extinguishing agent discharge jet nozzle 134 is connected to a fire extinguishing agent discharge copper pipe 125. The fire extinguishing agent discharge copper pipe 125 is connected to an in-package piping 142 by a joint 143.

[0055] A suction port 137 of the suction pipe 136 is provided in the power panel or control panel 135. The suction port 137 draws air from the power panel or control panel 135 by negative pressure and sends it to the ultra-high sensitivity smoke detector 138.

[0056] In the event of a fire 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 the pressure inside the detection tube 124 connected to the solenoid valve 141 to decrease. As the pressure inside the detection tube 124 decreases, extinguishant gas is supplied from the container valves 119, 129 to the intra-package piping 142. The extinguishant gas is discharged into the power panel or control panel 135 from the extinguishant discharge nozzle 134 via the extinguishant discharge copper pipe 125.

[0057] The method for inspecting these fire extinguishing agent storage containers 1, 101 and 107 will now be described. (1) Inspection method for fire extinguishing agent storage containers 1, 101, and 107 (1-1) How to check the amount of fire extinguishing agent (liquid level) Using a liquid level gauge or the like, the liquid level of the fire extinguishing agent sealed in liquid form in the fire extinguishing agent storage containers 1, 101, 107 is measured, and the surface temperature of the fire extinguishing agent storage container is measured using a surface thermometer or the like, and the measurement results are input into the management system.

[0058] (1-2) How to check the internal pressure of a fire extinguishing agent storage container The internal pressure of the fire extinguishing agent storage containers 1, 101, and 107 is measured using a pressure gauge. The measured pressure is input into the management system.

[0059] A method for inspecting the sensing tubes 24 and 124 will now be described. (2) Inspection method for sensing tubes 24 and 124 How to check the internal pressure of the sensing tube 24, 124 The internal pressure of the sensing tube 24, 124 is measured by a pressure gauge, and the measured pressure is input into the management system.

[0060] (3) Recording of measurement data (3-1) The measurement results of the amount of extinguishing agent, the pressure inside the storage container, and the pressure inside the sensing tube are recorded by the management system (management software installed on a terminal such as a tablet).

[0061] Figure 3 is an example of the display screen of the management system. (3-2) The two-dimensional code attached to the fire extinguisher package to be measured is read, or the number of the fire extinguisher storage container 1, 101, 107 is manually entered to display information about the fire extinguisher storage container 1, 101, 107, etc. When the "liquid level," "pressure," "temperature," and "pressure" of the sensing tube of the fire extinguisher storage container 1, 101, 107 measured during inspection are entered, a pass / fail judgment and related information are displayed. When the identifier of the fire extinguisher storage container and the amount of fire extinguisher in the fire extinguisher storage container or information related to the amount of fire extinguisher are entered, the reduction rate of the fire extinguisher in the fire extinguisher storage container since filling is displayed. When the identifier of the fire extinguisher storage container and the amount of fire extinguisher in the fire extinguisher storage container or information related to the amount of fire extinguisher in the fire extinguisher storage container since filling may be entered, the reduction rate of the fire extinguisher in the fire extinguisher storage container since the previous time may be displayed.

[0062] (3-3) The management system operation procedure is shown in Table 1.

[0063] [Table 1]

[0064] (4) Maintenance and management of fire extinguishing equipment In order to maintain this fire extinguishing equipment (cable tray fire extinguishing equipment 60, fire extinguishing device package 100) in a sound condition for the long term, in addition to regular inspections, the inspection results are used to predict the lifespan and deterioration of the equipment, and the equipment is replaced in a planned manner. This fire extinguishing equipment includes equipment that is at risk of leakage, such as "fire extinguishing agent storage containers filled at high pressure" and "detection tubes that are constantly pressurized," and if proper maintenance is not carried out, there is a possibility that the fire extinguishing agent will not be released effectively in the event of an emergency.

[0065] By carrying out the regular inspections described in (1) and (2), it becomes possible to discover and repair equipment defects that may be causing leaks. It also becomes possible to predict the time it will take for the equipment to lose function from its current state, and to take preventative measures. The following describes how to deal with the risk of leaks.

[0066] (4-1) Measures to prevent leakage from fire extinguishing agent storage containers Fire extinguishing agent storage containers are managed by checking the amount of fire extinguishing agent and the internal pressure of the container.

[0067] Figure 4 shows the predicted curve for maintaining functionality. As shown in Figure 4, when the results of this inspection for the amount of fire extinguishing agent and the internal pressure of the storage container are entered into the management system shown in section "(3) Recording of measurement data," a predicted period (A) until functionality can no longer be maintained will be displayed if the current trend continues based on the results of the previous inspection. To prevent loss of functionality, planned replacement, etc. will be required based on this period.

[0068] By inputting the results of the inspection measurements into the management system, a pass / fail decision and related information are displayed.

[0069] Figure 5 is a screen showing the predicted period until the management system loses its functionality. The "Predicted period until loss of functionality" in Figure 5 is displayed based on the predicted curve (dashed line in Figure 4) calculated based on the results of the previous and current inspections. Therefore, it is not displayed during the first inspection, but is displayed from the second inspection onwards. Also, when there are only a few sample measurement results, the error in the predicted curve will be large, but the accuracy will improve as the number of samples increases. Table 2 shows an example of an equipment renewal plan for the predicted period.

[0070] [Table 2]

[0071] By referring to the predicted period shown and the equipment renewal plan guidelines (examples) in Table 2, it is possible to create a renewal plan that will prevent loss of functionality while maintaining functionality.

[0072] (4-2) Measures to prevent leakage from the sensing tube In order to prevent a decrease in the internal pressure of the sensing tube 24, 124 from making it impossible to monitor the fire (temperature), this fire extinguishing equipment has the function of supplying nitrogen gas from the fire extinguishing agent storage container 1, 101, 107 to the sensing tube 24, 124 when the internal pressure of the sensing tube 24, 124 falls below a certain value, thereby maintaining the internal pressure of the sensing tube 24, 124 above a certain value.

[0073] By ensuring that the above-mentioned periodic inspections are carried out and by understanding the condition of the equipment through a management system, it is necessary to prevent loss of functionality due to leakage from the sensing tubes 24, 124.

[0074] If the internal pressure of the sensing tube 24, 124 continues to decrease and falls below a predetermined value, there is a possibility that the pressure in the fire extinguishing agent storage container 1, 101, 107 is decreasing.

[0075] The management system checks the amount of fire extinguishing agent and the internal pressure of fire extinguishing agent storage containers 1, 101, and 107, and if they are below the specified values, replace or refill fire extinguishing agent storage containers 1, 101, and 107. Also, even if they are not below the specified values, if the expected period until they will lose function is short, plan to replace or refill fire extinguishing agent storage containers 1, 101, and 107.

[0076] If the internal pressure of the sensing tubes 24, 124 continues to be below the lower control limit value every time an inspection is performed, it is possible that there is a continuous leak from the joints or the like of the sensing tubes 24, 124.

[0077] In this case, for example, an inspection is carried out using an ultraviolet absorption multi-gas sensor and laser light to detect trace amounts of fire extinguishing agent leaking from the detection tube 24, 124, to identify the leak location, and then the detection tube fittings, etc. are replaced.

[0078] Figure 6 shows an excerpt from 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 expected period until nitrogen gas supply from the fire extinguishing agent storage container 1,101 begins is displayed. In addition, if there is a drop in pressure, the amount of leakage and the pressure value converted from the leakage amount to the internal pressure of the container can also be displayed. These values can be used as a reference to plan the expected timing for re-pressurizing the sensing tube 24,124 and to plan the replacement or refilling of the fire extinguishing agent storage containers 1,101,107.

[0079] That is, when the identifier of the fire extinguishing agent storage container and the internal pressure of the fire extinguishing agent storage container are entered, the expected period until the fire extinguishing function is lost or until the pressure falls below the lower control limit is displayed ("Storage container internal pressure calculation result" in Figure 3).

[0080] Furthermore, by 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 about the amount of fire extinguishing agent, the system will display the expected period until the fire extinguishing function is lost or until the amount falls below the lower control limit ("Fire extinguishing agent amount calculation result" in Figure 3).

[0081] When the identifier of the fire extinguishing agent storage container and the internal pressure of the sensing tube connected to said fire extinguishing agent storage container are entered, the expected period until the fire extinguishing function is lost or until the pressure falls below the lower control limit is displayed ("Sensing tube calculation result" in Figure 3).

[0082] In this embodiment, the predicted period until function loss is displayed, but this is not limiting and the predicted period until the lower control limit is exceeded may also be displayed. When the lower control limit is exceeded, nitrogen gas is supplied from the fire extinguishing agent storage container 1, 101, 107 to the sensing tube 24, 124. The predicted period until the lower control limit is exceeded can be calculated by predicting from the rate of decrease so far and regressing the decrease curve (straight line).

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

[0084] (5-1) Explanation of the management system display screen 7 is a diagram for explaining the display screen of the management system. Table 3 shows each item of 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 for the tablet or other device.

[0087] Figure 8 shows the initial screen of the management system. (5-2-2) Loading container information Figure 9 shows the screen after reading the information on the fire extinguishant storage containers 1, 101, and 107. Press the two-dimensional code reading key to start the camera and read the two-dimensional code attached to the fire extinguishant storage containers 1, 101, and 107. Once the two-dimensional code is read, information on the fire extinguishant storage containers 1, 101, and 107 and information on the sensing tubes 24 and 124 are displayed.

[0088] For the second or subsequent measurements, the previous measurement value will be displayed in the cell for the current measurement value (fire extinguishing agent storage containers 1, 101, 107, sensing tubes 24, 124). (When a new value is entered, the previous measurement value will disappear.) Figure 10 shows the screen after the numbers for fire extinguishant storage containers 1, 101, and 107 have been entered. If the 2D code cannot be read, click on the fire extinguishant storage container number cell and use the numeric keypad to enter the container number engraved on the fire extinguishant storage container. (Press Enter to reflect the information in the cell.) Once the container number has been entered, information about the fire extinguishant storage container and sensing tube, as well as the previous measurement value, will be displayed.

[0089] (5-2-3) Liquid level input and temperature input Figure 11 shows the screen after the liquid level and temperature have been entered. Measure the liquid level in the fire extinguishing agent storage containers 1, 101, and 107, and enter the measurement results in the input cells. See "(1-1) How to check the amount of fire extinguishing agent (liquid level)."

[0090] When the measurement results are entered, the extinguishant amount judgment display, the extinguishant amount calculation result, and the pass / fail result of the inspection are displayed. When the detailed display key is pressed, a pop-up display shows the ratio to the previous measurement value. In other words, the extinguishant storage container contains the extinguishant as a liquid, and when information on the liquid level of the extinguishant is entered ("Enter measurement results" in Figure 11), the amount of extinguishant that has decreased since the previous time in the extinguishant storage container is displayed ("Display pop-up of 'previous value ratio' in Figure 11).

[0091] (5-2-4) Container internal pressure 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 input the measurement results into the input cell. See "(1-2) Inspection method for the internal pressure of a fire extinguishing agent storage container." After inputting the measurement results, the calculation result of the internal pressure of the storage container and the pass / fail result of the inspection are displayed.

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

[0093] When the measurement results are entered, the calculation results for the storage container internal pressure and the pass / fail result of the inspection are displayed. When the detailed display key is pressed, a pop-up will be displayed showing the amount of leakage since the last inspection and the value converted from the leakage amount to the container internal pressure.

[0094] That is, when the internal pressure of the sensing tube connected to the fire extinguishing agent storage container is input, the amount of leakage since the previous inspection is displayed ("Amount of leakage since the previous inspection" in Figure 13).

[0095] Furthermore, when the internal pressure of the sensing tube connected to the fire extinguishing agent storage container is input, the amount of leakage since the last inspection is converted into the decreased internal pressure of the container and the converted value is displayed ("Value converted from leakage amount to internal pressure of container" in Figure 13).

[0096] (5-2-6) Data storage Figure 14 shows the screen when saving data. Once you have finished entering all the measurement values, press the Save Inspection Results key to save the data. Press "OK" in the pop-up that asks "Do you want to save?", and if the data has been saved successfully, a pop-up will appear saying "Saved."

[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 information that you are currently entering. This makes it possible to inspect multiple fire extinguishing agent storage containers 1, 101, 107 in parallel. The data for a temporarily saved container can be called up by reading the two-dimensional code or by entering the container number, and the data 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] FIG. 17 is a block diagram showing the configuration of the management system 500. The management system 500 has an input unit 510, a calculation unit 520, a memory 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 using a camera, or may be input manually by a user. The input unit 510 is a part where information is input, and the input method is not limited to information input by an operator, and information may be input wirelessly or via a wired connection. For wireless communication, Wi-Fi (registered trademark) (IEEE 802.11 family standard, other mobile communication technologies, or a combination of these) can be used. Furthermore, for wired communication, for example, Ethernet (registered trademark) can be used.

[0100] The input unit 510 may communicate information via a gateway (GW) or without a GW. The input unit 510 may temporarily collect information regarding the amount and / or pressure of the extinguishing agent in the fire extinguishing agent storage containers 1, 101, 107 when a disaster (e.g., earthquake, tsunami, typhoon, war, riot, etc.) occurs. In these cases, the possibility of a fire occurring increases, so this is to confirm the operation of the fire extinguishing agent storage containers 1, 101, 107 before a fire occurs. Regarding 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 have information relating to location information. If the input unit 510 has information about the location of the fire extinguishant storage container 1, 101, 107, the fire extinguishant storage container 1, 101, 107 can be identified based on the location information. Furthermore, the location information may be acquired using a GPS (Global Positioning System). This makes it possible to acquire and link the location information with information about the amount and / or pressure of the fire extinguishant in the fire extinguishant storage container 1, 101, 107.

[0102] The storage unit 530 can store the previously input data and pass / fail judgment data, and 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, pass / fail judgment of the inspection results, and the like.

[0104] The display unit 540 displays the screens shown in FIGS. 8 to 16, including the results calculated by the calculation unit 520.

[0105] An output unit may be provided that outputs the contents of the screen displayed on the display unit 540 in a predetermined report format.
