Description

[Technical field]

[0001] An embodiment of the present invention relates to a flood monitor. [Background technology]

[0002] Conventionally, a containment room that contains various equipment including power supply equipment (substation equipment, uninterruptible power supply equipment, private power generation equipment, etc.) may be provided integrally with other spaces in the same building, or may be provided independently within the building site. When the containment room is provided integrally with other spaces, such as office space, factory space, living space, etc., the containment room may be provided on a lower floor (e.g., the first floor) or in the basement. When the containment room is provided independently within the building site, it may be a low-rise building. When the containment room is provided on such a low floor or in the basement, the equipment may malfunction early if flooding occurs, and therefore flood prevention measures are important. Thus, for example, various systems have been proposed that provide a flood detection sensor (water level sensor, water sensor, etc.) in part of the containment room and output an alarm if flooding occurs in the containment room.

[0003] [Patent Document 1] JP 2018-128768 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional systems detect whether or not a storage room is flooded, output an alarm, and based on the alarm, various countermeasures, such as drainage work, equipment shutdown work, etc., are determined by the person in charge. As a result, when flooding occurs, the countermeasures against flooding can be complicated, the timing of the countermeasures can vary, or they may not be implemented at the appropriate time.

[0005] Therefore, it would be meaningful to provide a flood monitoring device that can easily implement various flood prevention measures smoothly and at an appropriate time when flooding occurs in a storage room in which equipment is housed. [Means for solving the problem]

[0006] The water inundation monitoring device in the embodiment includes an acquisition unit and a control unit. The acquisition unit acquires detection information from water inundation detection sensors that detect water inundation levels and are provided in a plurality of pieces of equipment installed at different positions in the accommodation room. The control unit outputs different water inundation response information based on a combination of detection information acquired from at least two of the plurality of water inundation detection sensors. The flood response information is determined based on weighting based on at least the installation locations of multiple pieces of equipment and the flood level at the equipment.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The configuration of the embodiment described below, and the actions and results (effects) brought about by the configuration are merely examples, and are not limited to the contents described below.

[0009] FIG. 1 is an exemplary schematic top view showing a flooding monitoring system WS including a flooding monitoring device M according to an embodiment, and a storage room R to which the flooding monitoring device M is applied.

[0010] The water inundation monitoring device M includes at least an acquisition unit 10 and a control unit 12. The acquisition unit 10 acquires detection information from water inundation detection sensors 16 that detect water inundation levels, which are provided in each of a plurality of pieces of equipment 14 installed at different positions in the storage room R. Furthermore, the control unit 12 outputs different water inundation response information based on a combination of detection information acquired from at least two of the plurality of water inundation detection sensors 16. The acquisition unit 10 and the control unit 12 will be described in detail later.

[0011] As described above, the containment room R may be provided integrally with other spaces in the same building, or may be provided independently within the building site. When the containment room is provided integrally with other spaces, such as office space, factory space, or living space, it is often provided on a lower floor (e.g., the first floor) or in the basement. In this embodiment, a case will be described in which a flood monitoring device M is provided in a containment room R provided on a lower floor (e.g., the first floor) or in the basement of a building.

[0012] The storage room R is, for example, a box-shaped space that is substantially sealed except for the door Ra that constitutes the entrance and exit, and the walls and ceiling are made of, for example, concrete. Although a waterproof material, for example, an elastic material (rubber material, sponge material, etc.) is arranged on the outer edge of the openable and closable door Ra, the occurrence of a gap Rs is unavoidable, and when the periphery of the door Ra is flooded, water may flood into the storage room R. Therefore, in the storage room R of this embodiment, a water ingress detection sensor 16 is provided in each equipment 14 accommodated inside the storage room R. By providing the water ingress detection sensor 16 in each equipment 14, it becomes easier to grasp the water ingress situation inside the storage room R in a plan view, and a more detailed water ingress situation can be grasped compared to a case where the water ingress detection sensor 16 is provided at one location or the like inside the storage room R. In the case of FIG. 1, the door Ra is provided on, for example, the left wall of the storage room R, and for convenience, the direction away from the door Ra is defined as the X direction, and the width direction of the door Ra is defined as the Y direction.

[0013] In the case of FIG. 1, for example, four pieces of equipment 14 (14a, 14b, 14c, 14d) are installed on the floor surface Rf inside the storage room R. More specifically, the equipment 14a and the equipment 14b are arranged along the Y direction at a position close to the door Ra. In this embodiment, for convenience, an example is shown in which the water ingress cause part is present near the gap Rs, and the equipment 14a is arranged at a position closest to the gap Rs. In addition, the equipment 14c and the equipment 14d are arranged at a position far from the door Ra (a position far from the door Ra in the X direction). In FIG. 1, the equipment 14c is arranged at a position away from the gap Rs in the X direction with respect to the equipment 14a close to the water ingress cause part, and the equipment 14d is arranged at a position away from the door Ra in the X direction with respect to the equipment 14b. That is, the equipment 14b is arranged at a position farthest from the cause of water ingress (gap Rs).

[0014] Each facility 14 may be the same or different facilities. The facilities 14 may be, for example, substation facilities, uninterruptible power supply facilities, private power generating facilities, etc. that may be damaged by flooding and may cause breakdowns, leakage current, etc. In other embodiments, the facilities 14 are not limited to electrical facilities and may be devices that may be damaged by flooding.

[0015] The floor surface Rf of the storage chamber R is, for example, a downward slope facing in the reverse Y direction, and the wall surface Rb is set as the lowest area inside the storage chamber R. Therefore, when flooding occurs inside the storage chamber R, the water (rainwater, etc.) naturally flows along the floor surface Rf toward the wall surface Rb, for example, as shown in the broken line area W. In the case of FIG. 1, the drainage device 18 is disposed at a position along the wall surface Rb, which is the lowest area of ​​the floor surface Rf. The drainage device 18 is, for example, a pump-up type, and is configured to start draining water to the outside of the storage chamber R when water is present around the drainage device 18 (water intake). Note that the drainage method of the drainage device 18 can be appropriately selected as long as it is possible to drain water from inside the storage chamber R. Also, the drainage device 18 may be configured to have only a water intake at the position of the drainage device 18 in FIG. 1, and the main body of the drainage device 18 may be located at another position. Also, the water intake of the drainage device 18 may be opened into the inside of a cable pit Rp formed directly below each equipment 14 described later.

[0016] In this embodiment, if flooding occurs in the storage room R, the flood monitoring device M can notify the external system 20 of the flooding status in the storage room R successively or as needed. The external system 20 is provided in a location different from the storage room R, such as a remote management center or a management room on an upper floor of a building, so that a manager or the like can successively grasp the flooding status of the storage room R from a remote location. The external system 20 may be configured to be able to control the control unit 12 of the flood monitoring device M as appropriate.

[0017] 2 is an exemplary schematic explanatory diagram showing the arrangement of water inundation detection sensors 16 applied to facilities 14 in a water inundation monitoring device M. The arrangement of the water inundation detection sensors 16 for facilities 14a to 14d is basically the same.

[0018] The equipment 14 may be installed directly on the floor Rf of the storage room R, or may be installed on a stand that is appropriately installed on the floor Rf. In the case of Fig. 2, a cable pit Rp (a dug-out portion) for routing cables (not shown) associated with the equipment 14 is formed on the floor Rf corresponding to the position where the equipment 14 is installed. In other words, the cable pit Rp exists directly below the equipment 14.

[0019] In this embodiment, if flooding occurs in the storage room R, in order to detect the level of flooding in the equipment 14, flood detection sensors 16 are arranged to detect the water level at multiple positions on the outer periphery (outer wall, housing, etc.) of the equipment 14 along the Z direction from the cable pit Rp which is at the bottom of the height direction (Z direction) of the equipment 14 or further below the bottom.

[0020] In the case of Fig. 2, for example, a flood detection sensor 16a that detects "flood level 1" is disposed near the bottom surface Rpa of the cable pit Rp (for example, at a position 0.05 m above the bottom surface Rpa). "Flood level 1" is a level that indicates an early stage of flooding in the storage room R, or a situation in which a pool of water has formed due to a water leak or the like when handling water inside the storage room R. In other words, the flood detection sensor 16a can be said to be a sensor that outputs information that indicates that the flooding situation is not at a level that will cause direct water damage to the equipment 14, but is at a level that requires notification of the flooding situation to the external system 20 or the like.

[0021] Furthermore, flooding detection sensor 16b that detects "flooding level 2" is disposed at a position above flooding detection sensor 16a in the Z direction, for example, at a position a predetermined distance above main body bottom 14g of equipment 14 (for example, 0.1 m above main body bottom 14g). "Flooding level 2" is a level indicating a situation in which flooding in storage room R has progressed and active drainage measures, for example, are required. In this case, flooding detection sensor 16b can be said to be a sensor that outputs information indicating a level at which the flooding situation is not yet at a level that would cause direct water damage to equipment 14, but flooding from outside is progressing and it is therefore necessary to avoid water damage or delay the occurrence of water damage.

[0022] Furthermore, a water inundation detection sensor 16c that detects "water inundation level 3" is disposed at a position further above water inundation detection sensor 16b in the Z direction, for example, at a position a predetermined distance below the height at which electrical components included in equipment 14 are located (for example, at a position 0.2 m below the lowest electrical component). "Water inundation level 3" is a level indicating a situation in which the device itself must be shut down because the water inundation rate is faster than the drainage rate even if the storage room R is drained, the drainage process cannot be completed in time, and there is a risk of substantial water damage (malfunction, etc.) occurring in the equipment 14. In this case, water inundation detection sensor 16c can be said to be a sensor that outputs information indicating that the water inundation situation is at a level that requires the forced shutdown of the equipment 14 in which the water inundation detection sensor 16c is installed.

[0023] The detection information output from the flooding detection sensors 16a to 16c is sequentially transmitted to the acquisition unit 10. By locating the flooding detection sensors 16 at a plurality of positions in the height direction (Z direction) of each facility 14, for example, from the bottom of the facility 14 or a cable pit Rp dug further below the bottom, the flooding (submersion) state of the facility 14 to be detected can be accurately detected. When transmitting the detection information from each flooding detection sensor 16 to the acquisition unit 10, the transmission may be wired or wireless. In addition, in the example of FIG. 2, the flooding detection sensors 16a to 16c are individually arranged at positions corresponding to each flooding level, but the flooding detection sensor 16 may have a plurality of detectors, and each detector may be arranged at the position of the flooding detection sensor 16a, the position of the flooding detection sensor 16b, and the position of the flooding detection sensor 16c. In addition, in the example of FIG. 2, the flooding level is shown as three levels, but it is sufficient that the flooding level can be detected at a plurality of positions in the Z direction, and may be, for example, two levels or four or more levels. In addition, in the example of Figure 2, the water inundation detection sensor 16 is installed substantially in contact with the equipment 14. However, as long as it can detect the substantial water inundation state (submersion state, water level) of the equipment 14 to be detected, it does not have to be installed in contact with the equipment 14 and may be located in the vicinity.

[0024] A well-known sensor can be used as the water submersion detection sensor 16. For example, a non-contact ultrasonic type, electromagnetic wave type, laser type, capacitance type, etc. can be used as the water submersion detection sensor 16. The water submersion detection sensor 16 may also be a contact type sensor such as an electrode type that applies a voltage between electrodes and detects the presence or absence of liquid based on the flow of current, a water pressure detection type that detects water pressure due to contact with water, or a float type.

[0025] 3 is an exemplary schematic block diagram showing the configuration of the submergence monitoring device M. As described above, the submergence monitoring device M includes an acquisition unit 10 and a control unit 12.

[0026] The acquisition unit 10 sequentially acquires detection information from the flood detection sensors 16 provided in each of the facilities 14, and provides the information to the control unit 12. Note that the acquisition unit 10 may function in a standby mode in which detection information is acquired at a relatively long interval until detection information (e.g., detection information of flood level 1) is acquired for the first time from any one of the flood detection sensors 16, and after acquiring the initial detection information, it may function in a sequential acquisition mode in which the detection period is shorter than that in the standby mode.

[0027] The control unit 12 includes, for example, a determination unit 12a, a notification unit 12b, a drainage control unit 12c, and an apparatus stop control unit 12d.

[0028] The determination unit 12a determines the flooding state in the storage room R. Specifically, the determination unit 12a generates flood response information that is determined based on weighting based on at least the installation positions of the multiple pieces of equipment 14 and the flooding levels acquired from the flood detection sensors 16 of the equipment 14.

[0029] The flood response information is at least one of flood warning information, drainage control information, and equipment 14 shutdown control information.

[0030] The flood warning information is information generated when the acquisition unit 10 acquires, for example, detection information of "flood level 1" from one or more than all of the flood detection sensors 16. For example, when "flood level 1" is output from any one of the flood detection sensors 16 and detection information is not acquired from the other flood detection sensors 16, the determination unit 12a determines that flooding is in the early stage or that a pool of water has occurred due to a water leak or the like inside the accommodation room R, generates "alarm 1" indicating minor flooding, and provides it to the notification unit 12b. That is, the notification unit 12b executes alarm output control to provide a signal indicating "alarm 1" to the external system 20 based on a combination of detection information acquired from at least two flood detection sensors 16. When the external system 20 acquires a signal indicating "alarm 1", it executes display output and audio output to make the manager or the like recognize that minor flooding has occurred. In this case, the notification unit 12b may also notify information specifying the flood detection sensor 16a (equipment 14) that detected "Flood Level 1" and the specific water level (submersion status, etc.).

[0031] Furthermore, when "Flooding Level 1" is output from a plurality of (e.g., two) flooding detection sensors 16, but not all of them, the determination unit 12a determines that flooding in the storage room R is progressing and that it is necessary to check the storage room R immediately. In this case, the determination unit 12a generates "alarm 2" indicating the progress of flooding and provides it to the notification unit 12b. That is, the notification unit 12b executes alarm output control to provide a signal indicating "alarm 2" to the external system 20 based on a combination of detection information acquired from at least two flooding detection sensors 16. When the external system 20 acquires a signal indicating "alarm 2", it performs display output and audio output to make the manager or the like aware that flooding is progressing. In this case, it is desirable that the display output and audio output are output in an emphasized manner compared to the case of "alarm 1". That is, when the display color of "alarm 1" is, for example, "yellow", the display color of "alarm 2" is displayed, for example, in "red", or when the alarm sound of "alarm 1" is, for example, only a message, the alarm sound of "alarm 2" may be added to the message and a warning sound or the like may be output for emphasis.

[0032] Furthermore, when the acquisition unit 10 acquires detection information of "flood level 1" from all the flood detection sensors 16, the determination unit 12a determines that flooding has been detected throughout the interior of the storage room R, that is, over a wide area. In this case, the determination unit 12a determines that rainwater or the like may be overflowing from the cable pit Rp, generates drainage control information for driving the drainage device 18, and provides it to the drainage control unit 12c. When the drainage control unit 12c acquires the discharge control information, it executes drainage control and drives the drainage device 18 to drain rainwater or the like present around the drainage device 18 to the outside of the storage room R. Note that, when the water intake of the drainage device 18 is installed on the floor surface Rf near the drainage device 18, the drainage device 18 may be provided with a water level sensor similar to the flood detection sensor 16, and even if detection information of "flood level 1" is output from all the flood detection sensors 16, if there is no rainwater or the like present around the drainage device 18, the discharge control information may be invalidated to suppress unnecessary driving of the drainage device 18. Furthermore, when the water intake of the drainage device 18 is open to each cable pit Rp, the drainage device 18 may be driven at the time when detection information of "flood level 1" is output from all of the flood detection sensors 16. In this way, the determination unit 12a can more accurately detect the flooding state in the storage room R based on a combination of detection information acquired from at least two flood detection sensors 16, and determine whether or not to operate the drainage device 18. As a result, the water in the storage room R can be drained at an appropriate time, and the spread of water damage in the storage room R can be avoided or delayed, making it easier to take the next measure.

[0033] When the acquisition unit 10 acquires detection information of "flood level 2" from any of the flood detection sensors 16, the determination unit 12a may determine that there is a possibility that the equipment 14 may be damaged within a short period of time inside the accommodation room R. In this case, in order to perform forced drainage immediately, drainage control information may be generated and provided to the drainage control unit 12c to execute drainage control.

[0034] Furthermore, when the acquisition unit 10 acquires detection information of "flood level 2" from all flood detection sensors 16, the determination unit 12a can determine that water that has flooded a wide area in a short time inside the containment room R may damage the equipment 14. In this case, it is dangerous to enter the containment room R because there is a possibility of electric shock due to leakage from the equipment 14. Therefore, the determination unit 12a causes the notification unit 12b to execute evacuation control to output flood warning information indicating evacuation from the containment room R. In this case, the notification unit 12b notifies the external system 20 of an evacuation command and displays an evacuation message (no entry message) or the like on a warning light or display device installed on the external wall surface or internal wall surface of the containment room R. The notification unit 12b may also output an evacuation message or a warning sound from a speaker or the like.

[0035] Furthermore, when multiple (e.g., two) flood detection sensors 16 output "flood level 2," the determination unit 12a can determine that there is a possibility that flooded water will cause damage to the equipment 14 within a short period of time. In this case, the determination unit 12a provides the equipment stop control unit 12d with stop control information for executing a total equipment stop that stops (e.g., stops the power supply) all of the equipment 14 present inside the accommodation room R, and causes the equipment stop control unit 12d to execute the total equipment stop control.

[0036] If the acquisition unit 10 acquires detection information of "flood level 3" from any of the flood detection sensors 16, the determination unit 12a can determine that there is an even higher possibility that flooded water will damage the equipment 14. In this case, the determination unit 12a can estimate that even equipment 14 in which flooding has not yet been detected will similarly reach "flood level 3" within a short period of time. Then, the determination unit 12a provides the equipment stop control unit 12d with stop control information for executing a total equipment stop that stops (stops power supply, etc.) all equipment 14 present inside the accommodation room R, and causes the equipment stop control unit 12d to execute total equipment stop control.

[0037] In this manner, the control unit 12 of this embodiment generates and outputs at least one of flood warning information, drainage control information, and stop control information as different flood response information based on a combination of detection information acquired from at least two of the multiple flood detection sensors 16. As a result, appropriate flood countermeasures can be implemented in stages at appropriate times.

[0038] In addition, the flood response information may be determined by weighting based on at least the installation positions of the plurality of facilities 14 and the flood level in the facilities 14. For example, the seriousness (danger) of flooding differs between a case where "flood level 2" is detected in the facility 14a close to the cause of flooding (gap Rs) and a case where "flood level 2" is detected in the facility 14d far from the cause of flooding. In other words, when "flood level 2" is detected in a position far from the cause of flooding, it is considered that the flooding situation is more serious in a position close to the cause of flooding. Therefore, when the flood detection sensor 16 of the facility 14d acquires detection information indicating "flood level 2", for example, even if "flood level 2" has not been reached at the position of the facility 14c, the weighting of the determination in the determination unit 12a may be increased, and "evacuation control" may be executed as one of the severest responses to flood warning information. As a result, more appropriate flood countermeasures can be executed at a more appropriate time. Such weighting at the time of determination may be changed depending on the importance of the facility 14.

[0039] The processing flow of the flood monitoring device M configured as above will be described with reference to the flowchart shown as an example in FIG.

[0040] The acquisition unit 10 monitors whether the water inundation detection sensor 16 is turned ON at a predetermined cycle (S100), that is, whether detection information has been acquired. As described above, the acquisition unit 10 may function in a standby mode in which detection information is acquired at a relatively long cycle until it first acquires detection information from the water inundation detection sensor 16 (for example, detection information of water inundation level 1), and after acquiring the initial detection information, it may function in a sequential acquisition mode with a shorter detection cycle than the standby mode. In this case, the processing load on the control unit 12 can be reduced. If the acquisition unit 10 cannot acquire detection information from the water inundation detection sensor 16 (No in S100), the acquisition unit 10 temporarily ends this flow and performs the detection information acquisition process again at the next detection cycle.

[0041] In the process of S100, when detection information is acquired from the flooding detection sensor 16 (Yes in S100), the determination unit 12a determines whether the acquired detection information is "flooding level 1" or not (S102). When the acquired detection information is "flooding level 1" (Yes in S102) but multiple flooding detection sensors 16 are not ON (No in S104), that is, when only one of the flooding detection sensors 16 detects the detection information and no detection information is acquired from the other flooding detection sensors 16, the determination unit 12a generates mild flooding warning information. That is, it executes output control of "alarm 1" (S106). That is, the determination unit 12a determines that the detected flooding state is the early stage of flooding or that a puddle has occurred inside the accommodation room R due to a water leak or the like, generates information about "alarm 1" and provides it to the notification unit 12b. The notification unit 12b outputs information indicating "alarm 1" to the external system 20 and ends this flow for the time being. When the external system 20 acquires information indicating "Alarm 1", it prompts the manager or the like to check the containment room R. For example, it may output a display message such as "There is slight flooding or puddles of water due to leakage or the like in the containment room, so please check," or execute a process to turn on a minor warning light (e.g., a yellow warning light). Also, instead of or in addition to the display message or turning on the warning light, it may output a voice message with similar content, or output a low-volume warning sound, etc.

[0042] In the process of S104, if multiple water inundation detection sensors 16 are ON (Yes in S104) and the acquisition unit 10 acquires multiple pieces of detection information, but not all of the water inundation detection sensors 16 are ON (No in S108), the determination unit 12a executes output control of "alarm 2" (S110). That is, for example, this is the case when "water inundation level 1" is output from two water inundation detection sensors 16. In this case, the determination unit 12a determines that the water inundation in the storage room R is progressing and that it is necessary to check the storage room R immediately, generates "alarm 2" indicating the progress of water inundation, and provides it to the notification unit 12b. Then, the notification unit 12b executes alarm output control to provide a signal indicating "alarm 2" to the external system 20, and once ends this flow. As described above, when the external system 20 acquires a signal indicating "alarm 2", it performs a more emphasized display output or audio output to make the manager or the like recognize that water inundation is progressing.

[0043] In the processing of S108, if all the water inundation detection sensors 16 are ON (Yes in S108), the judgment unit 12a judges that water inundation has been detected throughout the storage room R, i.e., over a wide area, and outputs a drainage control signal to the drainage control unit 12c indicating that the drainage device 18 should be driven, and causes the drainage device 18 to perform drainage control (S112), and then terminates this flow.

[0044] In addition, in the process of S102, if the detection information acquired by the acquisition unit 10 is not "flood level 1" (No in S102), for example, if the detection information acquired by the acquisition unit 10 is "flood level 2" (Yes in S114). If the detection information of "flood level 2" is not acquired from multiple flood detection sensors 16 (No in S116), that is, if there is only one flood detection sensor 16 that has detected "flood level 2". In this case, it is estimated that the water level in the storage room R continues to rise due to flooding. In this case, the determination unit 12a determines that the water damage can be minimized by a prompt drainage response at an early stage, outputs a drainage control signal to the drainage control unit 12c indicating that the drainage device 18 is to be driven, and causes the drainage device 18 to execute drainage control (S112), and once ends this flow.

[0045] Furthermore, in the process of S116, when the acquisition unit 10 acquires detection information of "flood level 2" from a plurality of flood detection sensors 16 (Yes in S116) and acquires detection information of "flood level 2" from all of the flood detection sensors 16 (Yes in S118), it can be determined that the lower parts of all of the equipment 14 in the storage room R are submerged in water and the inside of the storage room R is in a state where there is a risk of electric shock due to leakage current. Therefore, the determination unit 12a causes the notification unit 12b to execute evacuation control to encourage evacuation from the storage room R as flood warning information (S120), and once ends this flow. The notification unit 12b notifies the external system 20 of the evacuation command, and, for example, displays an evacuation message (no entry message) on a warning light or display device installed on the outer wall surface or inner wall surface of the storage room R, or outputs an evacuation message or a warning sound from a speaker or the like.

[0046] In the process of S118, if the acquisition unit 10 acquires multiple pieces of detection information of "flood level 2" but not all of the flood detection sensors 16 are in an ON state for "flood level 2" (No in S118), for example, the detection information of "flood level 2" is acquired from the flood detection sensors 16 installed in two pieces of equipment 14. In this case, the determination unit 12a determines that there is a possibility that flooded water will damage multiple pieces of equipment 14 in a short period of time. In this case, the determination unit 12a provides the equipment stop control unit 12d with stop control information for executing a total equipment stop that stops (stops the power supply) all of the equipment 14 present inside the accommodation room R, and has the equipment stop control unit 12d execute the total equipment stop control (S122), and once ends this flow.

[0047] Furthermore, in the process of S114, if the flood level of the detection information acquired by the acquisition unit 10 is neither "flood level 1" nor "flood level 2" (No in S114), that is, if it is "flood level 3". In this case, the determination unit 12a estimates that even equipment 14 in which flooding has not yet been detected will similarly reach "flood level 3" within a short period of time. In this case as well, stop control information for executing a total equipment stop that stops (stops power supply to) all equipment 14 present inside the accommodation room R is provided to the equipment stop control unit 12d, and the equipment stop control unit 12d is caused to execute total equipment stop control (S122), and this flow is temporarily terminated.

[0048] In this way, with the flood monitoring device M of this embodiment, when flooding occurs in the storage room R housing the equipment 14, the flooding status inside the storage room R can be easily grasped from a remote location, and more appropriate flood prevention measures can be easily implemented in stages at an appropriate timing. In other words, flood monitoring of the storage room R can be performed more efficiently and safely.

[0049] In the above-described embodiment, the case where the storage room R is provided on a lower floor or underground together with other spaces has been described. In other embodiments, even when the storage room R is configured as an independent low-rise, for example, one-story building on the premises, the flood monitoring device M of the present embodiment can be applied and can function in the same manner and obtain the same effect. In the above-described embodiment, as shown in FIG. 2, an example is shown in which a cable pit Rp is provided directly below the equipment 14 and the flood detection sensor 16a is located at the lowest position. In other embodiments, when a cable pit Rp is not provided, the flood detection sensor 16a may be installed at a predetermined height from the floor surface Rf, for example, at the upper end position of the lower frame of the equipment 14, and the same effect can be obtained.

[0050] 1 shows an example in which the floor surface Rf is inclined so that the wall surface Rb is at its lowest, but the drainage device 18 (the water intake of the drainage device 18) may be located at the lowest position of the floor surface Rf, and for example, the floor surface Rf may be in a "cone shape" in which the center position is the lowest, and the same effect can be obtained. Note that an adjuster or the like may be provided on the underside of each piece of equipment 14 so that the horizontal installation of the equipment 14 itself can be ensured even if the floor surface Rf is inclined.

[0051] Although the embodiment of the present invention has been described above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. The above embodiment is included in the scope and gist of the invention, and is included in the scope of the invention and its equivalents described in the claims. [Explanation of symbols]
