Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof device, a waterproof device monitoring system, and a waterproof device monitoring method that dams up water with a waterproof plate that stands up due to buoyancy.

In recent years, in addition to heavy rains caused by typhoons and active fronts, due to the effects of climate change and the heat island phenomenon, guerrilla downpours in short periods of time have been observed in various places, mainly in urban areas. Many flood damages have been reported. Among them, entrances to underground spaces such as subways, underground malls, underground parking lots, underground elevators, etc., and entrances to living spaces such as condominiums, office buildings, public facilities, shopping centers, etc., are particularly damaged.

Waterproof boards are used to prevent rainwater from entering during floods. As one type of waterproof board, a waterproof board configured to block a passage by the buoyancy of water is known (see FIG. 8). Normally, this waterproof board 900 is housed in a recess 902a provided in the floor surface 902 in a laid down position. , thereby blocking passage 901 (defined by floor 902, side walls 903 and side walls 904). Even if the water level rises due to torrential rain or the like, the waterproof plate 900 can prevent water from entering from the entrance.

This waterproof plate 900 automatically stands up to block the passage 901 when the water level rises. When the water level drops, the waterproof plate 900 automatically falls down and is accommodated in the recess 902a. During this time, a person does not need to perform any operation. Therefore, the user cannot know whether the waterproof plate has been activated or not, and if so, when it has been activated. If a surveillance camera were to be installed to monitor the operation of the waterproof plate, it would be necessary to install a power source and consume a large amount of power, resulting in high costs.

Moreover, the waterproof plate is mainly activated when a torrential rain occurs, so the actual frequency of activation of the waterproof plate is not necessarily high. Therefore, the maintenance of waterproof plates tends to be neglected. If the maintenance of the waterproof plate is inadequate, there is a risk that it will not start in an emergency. If there is insufficient drainage at the place where the waterproof board is installed, the water level will rise only in the place where the waterproof board is installed, even if the amount of rainfall is not large enough to cause flooding. It is also possible for the board to stand up. Therefore, in order to prompt the user of the waterproof board to perform maintenance, it has been desired to acquire information on the waterproof board.

In addition, since the embodiments described below are preferred embodiments of the present invention, various technically preferable limitations are applied, but the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these modes.

(Embodiment of waterproof device)
An embodiment of a waterproof device according to the present invention will be described with reference to FIGS. 1 to 3. FIG. FIG. 1 is a diagram showing a waterproof device according to an embodiment of the present invention, and is a partially broken plan view showing a state in which a waterproof plate is laid down. 2 is a cross-sectional view showing a cross-section taken along line AA in FIG. 1, and FIG. 3 is an enlarged cross-sectional view showing a portion B in FIG. In addition, in FIG. 2, the state in which the waterproof plate is erected is shown with a two-dot chain line.

First, the configuration of a waterproof device 10 according to this embodiment will be described with reference to FIGS. The waterproof device 10 is installed in the passage 90. - 特許庁The passage 90 is partitioned by a floor surface 91 and side walls 93 and 94, and has an entrance (not shown) on the right side in FIGS. In the event of a flood, water flows through passageway 90 in the direction indicated by the arrow.

The waterproof device 10 includes a waterproof plate 11, a hinge 12, a proximity sensor 13, a water level sensor 14, a control box 15 and an antenna 16 as main components. As shown in FIG. 1 , the waterproof plate 11 has a rectangular shape in plan view, and is connected to the floor surface 91 by hinges 12 . The specific gravity of the waterproof plate 11 is set smaller than that of water, and when a flood occurs and the water level in the passage 90 rises, the waterproof plate 11 stands up due to buoyancy (see the two-dot chain line in FIG. 2). The space between the waterproof plate 11 and the floor 91 and side walls 93 and 94 is watertight. prevent inflow.

The waterproof plate 11 is connected to the floor surface 91 by the hinges 12 as described above. A rotating shaft 12a of the hinge 12 is arranged along one side of the waterproof plate 11, and the waterproof plate 11 is rotatable around the rotating shaft 12a. The hinge 12 is arranged such that the rotating shaft 12 a is parallel to the floor surface 91 . As shown in FIGS. 1 and 2, the side walls 93 and 94 are provided with stoppers 93a and 94a, respectively, and the waterproof plate 11 rotating clockwise in FIG. Clockwise rotation is restricted. Any means can be applied to limit the rotation of the waterproof plate 11 .

A recess 91a is formed in the floor surface 91, and when the waterproof board 11 is laid down, the waterproof board 11 is accommodated in the recess 91a as shown in FIG. At this time, the lower surface of the waterproof plate 11 is in contact with the support surface 91b in the recess 91a, and the upper surface of the waterproof plate 11 is at the same height as the floor surface 91.

A grating 95 is provided in the recess 91a. The grating 95 is installed such that its upper surface is at the same height as the floor surface 91 . When it rains, rainwater flows from the floor surface 91 through the grating 95 and accumulates in the recess 91a. A drain port 91c is provided inside the concave portion 91a, and the drain port 91c is connected to a drain pipe 91d leading to the outside. Rainwater in the recessed portion 91a is discharged to the outside through the drain port 91c and the drain pipe 91d.

When the amount of rainwater flowing into the recess 91a exceeds the drainage capacity of the drain port 91c, rainwater begins to accumulate in the recess 91a. When the water level in the recess 91a rises, buoyancy is generated in the waterproof plate 11 lying down in the recess 91a, and it starts to stand up. That is, since the floor surface 91 is provided with the recessed portion 91a for housing the waterproof plate 11, the waterproof plate 11 starts to stand up early in the event of a flood. After starting the standing motion, the waterproof plate 11 rotates clockwise in FIG. 2 around the rotating shaft 12a as the water level rises. do.

Next, the proximity sensor 13, the water level sensor 14, the control box 15, and the antenna 16, which are elements for acquiring information about the waterproof plate 11, will be described with reference to FIGS. As shown in FIG. 3, the proximity sensor 13 is composed of a detection portion 13a for detecting magnetism and a magnet 13b. The sensing portion 13a is coupled to a structure fixed within the recess 91a. Magnet 13b is coupled to waterproof plate 11 . The detector 13a and the magnet 13b are arranged to face each other with the waterproof plate 11 lying down.

The detection unit 13a is connected to the control box 15 with a cable. The proximity sensor 13 outputs an OFF signal when the magnet 13b is closer than a predetermined distance to the detector 13a, and an ON signal when the magnet 13b is away from the detector 13a by a predetermined distance or more. out.

That is, when the waterproof plate 11 is raised from the laid down posture shown by the solid line in FIG. A signal is given. In this way, the proximity sensor 13 functions as a waterproof plate posture detection means for detecting the posture of the waterproof plate 11 .

In processing information about the waterproof board 11, when the proximity sensor 13 outputs an OFF signal, the waterproof board 11 is assumed to be in the lying posture, and when the proximity sensor 13 outputs an ON signal, the waterproof board 11 It can be treated as being in a standing posture. The boundary between the lying posture and the standing posture can be arbitrarily set depending on the sensitivity of the proximity sensor 13 and the installation position.

The water level sensor 14, as shown in FIG. 3, is located below the grating 95 and is coupled to a structure fixed within the recess 91a. The water level sensor 14 is configured to output a signal to the control box 15 via a cable. The water level sensor 14 is configured such that a float 14a having a smaller specific gravity than water can move up and down. The water level sensor 14 outputs an ON signal when the float 14a reaches the upper end 14b, and outputs an OFF signal when the float 14a does not reach the upper end 14b. Therefore, the water level sensor 14 functions as a water level detecting means for detecting the water level in the recess 91a, and outputs an ON signal when the water level is equal to or higher than a predetermined water level, and outputs an OFF signal when the water level is less than the predetermined water level.

In processing information about the waterproof plate 11, if the water level sensor 14 outputs an OFF signal, the water level in the recess 91a is assumed to be low, and if the water level sensor 14 outputs an ON signal, the recess 91a Water levels within can be treated as being high water levels.

The threshold for distinguishing between the low water level and the high water level can be arbitrarily set according to the installation position of the water level sensor 14 (the position of the upper end 14b). When the water level at which the waterproof plate 11 begins to stand up due to buoyancy is taken as a threshold, the proximity sensor 13 and the water level sensor 14 turn from OFF signals to ON signals almost at the same time as the water level in the recess 91a rises. As the water level in the recessed portion 91a decreases, the proximity sensor 13 and the water level sensor 14 turn from ON signals to OFF signals almost at the same time.

When the water level lower than the water level at which the waterproof plate 11 starts to stand up due to buoyancy is taken as the threshold value, as the water level in the recess 91a rises, the water level sensor 14 first turns from the OFF signal to the ON signal, and then the waterproof plate 11. starts to rise and the proximity sensor 13 changes from the OFF signal to the ON signal. As the water level in the recessed portion 91a decreases, the waterproof plate 11 first takes the fallen posture, the proximity sensor 13 turns from the ON signal to the OFF signal, and then the water level sensor 14 turns from the ON signal to the OFF signal. In this embodiment, the water level sensor 14 is arranged so that the water level lower than the water level at which the waterproof board 11 begins to stand due to buoyancy serves as the threshold for distinguishing between the low water level and the high water level.

As shown in FIG. 3, control box 15 is positioned below grating 95 and is coupled to a structure fixed within recess 91a. A control board (not shown) and a battery (not shown) are housed inside the control box 15 . A proximity sensor 13 , a water level sensor 14 and an antenna 16 are connected to the control board of the control box 15 . The control box 15 acquires signals from the proximity sensor 13 and the water level sensor 14 and wirelessly transmits them to the outside via the antenna 16 . A battery housed in the control box 15 supplies power to the control board and devices connected thereto. Also, the control box 15 is waterproofed and configured to operate normally even when the recessed portion 91a is flooded.

The antenna 16 has a thin, substantially rectangular shape and is mounted on the side wall 93 as shown in FIGS. The antenna 16 is connected to the control box 15 and wirelessly transmits information regarding the waterproof plate 11 acquired by the proximity sensor 13 and the water level sensor 14 to the base station. As will be described later, the information sent to the base station is sent to the server via the communication network, and the server processes the information regarding the waterproof plate 11 . That is, the antenna 16 functions as transmitting means for transmitting information on the waterproof plate 11 to the server.

The control box 15 and the antenna 16 are configured to transmit wirelessly to the base station only when the proximity sensor 13 and the water level sensor 14 change from an OFF signal to an ON signal and vice versa. ing. That is, regarding the posture of the waterproof board 11, information is transmitted to the base station only when the lying posture is changed to the standing posture and when the standing posture is changed to the lying posture. Information about the water level at the place where the waterproof board 11 is installed is transmitted to the base station only when the water level changes from low to high and when the water level changes from high to low. With this configuration, the antenna 16 has less opportunity to transmit radio waves, and power consumption is reduced, so that the life of the battery is extended, and information about the waterproof plate can be transmitted for a long period of time without replacing the battery. It becomes possible. Also, since the amount of information to be transmitted is small, it is sufficiently possible to transmit even using a low-speed communication circuit.

Although the illustrated antenna 16 is installed outside the concave portion 91a, it can be installed at any location so that radio waves can reach the base station.

Information about the waterproof board 11 can be obtained by using the waterproof device 10 of the present embodiment. Moreover, appropriate processing can be performed according to the acquired information about the waterproof plate 11 . Also, the waterproof plate 11 can be remotely monitored.

I have. The base station 20 is configured to be able to receive a signal transmitted by the waterproof device 10 (antenna 16), and is connected to a communication network 30. FIG. The server 40 is connected to the communication network 30 and is capable of transmitting and receiving information, and processes information regarding the waterproof board. The base station 50 is configured to be able to wirelessly communicate with the mobile terminal 60 and is connected to the communication network 30 . A fixed terminal 70 is connected to the communication network 30 . Here, the mobile terminal 60 and the fixed terminal 70 are terminals possessed by users who need information on waterproof boards. Users include not only owners and managers of facilities in which waterproof boards are installed, but also managers, distributors, and manufacturers of waterproof boards.

The server 40 has a communication unit 41 connected to the communication network 30 , a control unit 42 connected to the communication unit 41 , and a storage unit 43 connected to the control unit 42 . The control unit 42 processes the received information about the waterproof plate and controls the operation of the server 40 as a whole. The communication unit 41 receives information about the waterproof board and transmits the information to the mobile terminal 60 and/or the fixed terminal 70 under the control of the control unit 42 . That is, the communication unit 41 functions as receiving means for receiving information transmitted from the waterproof device 10, and the communication unit 41 and the control unit 42 function as notification means for notifying the user of information regarding the waterproof board. The storage unit 43 records information about the waterproof plate under the control of the control unit 42 . That is, the storage unit 43 functions as recording means for recording information about the waterproof plate.

Next, information exchange and information processing in this waterproof device monitoring system 100 will be described.

(Monitoring the Posture of Waterproof Plates)
The waterproof device 10 acquires the posture of the waterproof plate 11 as information about the waterproof plate 11 by the proximity sensor 13 described above, and transmits the information to the server 40 via the antenna 16 . The communication unit 41 of the server 40 receives information on the waterproof board, and the control unit 42 determines whether the waterproof board 11 is in the lying down posture or the standing posture based on the signal from the proximity sensor 13 . That is, the control unit 42 functions as undulation determination means. As described above, the proximity sensor 13 sends an ON signal when the waterproof plate 11 is raised from the lying posture by a predetermined angle or more, and sends an OFF signal when the raised angle is smaller than the predetermined angle. If the proximity sensor 13 outputs an ON signal, the control unit 42 determines that it is in the standing posture, and if it outputs an OFF signal, it determines that it is in a lying posture.

When it is determined that the waterproof board 11 is in the standing posture, the control unit 42 sends a message to the effect that the waterproof board is standing up from the communication unit 41 via the communication network 30 to the mobile terminal 60 and/or the fixed terminal. 70. Thereby, the user can recognize that the waterproof board 11 is erected. Note that this message can adopt any form such as e-mail or push transmission.

Further, the control unit 42 records the determined posture of the waterproof plate 11 in the storage unit 43 . The information to be stored includes an identifier assigned to each waterproof board, the date and time when it changed from a lying posture to a standing posture, the date and time when it changed from a standing posture to a lying posture, the date and time when a message was sent to the user, and the content of the message. etc. are preferably selected.

As described above, the proximity sensor 13 of the waterproof device 10 transmits a signal to the server 40 only when the OFF signal changes to the ON signal and when the ON signal changes to the OFF signal. Therefore, when the control unit 42 receives that the proximity sensor 13 has changed from the OFF signal to the ON signal, it is sufficient to determine that the waterproof plate is in the upright posture. If the information is received, it may be determined that the waterproof board is in the lying posture.

(Monitoring the Water Level in Places Where Waterproof Boards Are Installed)
The waterproof device 10 acquires the water level at the place where the waterproof board is installed as information about the waterproof board by the water level sensor 14 described above, and transmits the information to the server 40 via the antenna 16 . The communication unit 41 of the server 40 receives information on the waterproof board, and the control unit 42 determines that the water level at the place where the waterproof board is installed is higher than a predetermined water level based on the signal from the water level sensor 14. or a low water level below a predetermined water level. As described above, the water level sensor 14 sends an ON signal when the water level is equal to or higher than the predetermined water level, and an OFF signal when the water level is less than the predetermined water level. If it is an OFF signal, it is determined that the water level is high, and if it is an OFF signal, it is determined that the water level is low.

When it is determined that the water level at the location where the waterproof plate is installed is high, the control unit 42 transmits a message indicating that the water level is rising from the communication unit 41 to the mobile terminal 60 and the mobile terminal 60 via the communication network 30. /or to the fixed terminal 70; This allows the user to recognize that the water level is rising at the place where the waterproof board is installed. Note that this message can adopt any form such as e-mail or push transmission.

Further, the control unit 42 records the determined water level at the location where the waterproof board is installed in the storage unit 43 . The recorded information includes the identifier assigned to each waterproof board, the date and time when the water level changed from low to high, the date and time when the water level changed from high to low, the date and time when the message was sent to the user, and the content of the message. etc. are preferably selected.

As described above, the water level sensor 14 of the waterproof device 10 transmits a signal to the server 40 only when the OFF signal changes to the ON signal and when the ON signal changes to the OFF signal. Therefore, when the control unit 42 receives that the water level sensor 14 has changed from the OFF signal to the ON signal, it is sufficient to determine that the water level is high. If so, it should be determined that the water level is low.

(Notification of Abnormality of Waterproof Device)
It is normal for a waterproof plate to turn to an upright position as the water level rises at the place where it is installed. If the waterproof board stands up without the water level rising, it means that something is wrong with the waterproof system (someone caused the waterproof board, etc.). The waterproof device monitoring system 100 can notify the user of an abnormality.

That is, in a state in which the water level at the location where the waterproof board is installed is determined to be low (a state in which the water level sensor 14 is outputting an OFF signal), the controller 42 determines that the posture of the waterproof board is the standing posture. (When the proximity sensor 13 changes from an OFF signal to an ON signal), the control unit 42 sends a message to the effect that the waterproof plate is operating abnormally from the communication unit 41 via the communication network 30 to the mobile terminal 60. and/or to the fixed terminal 70 . This allows the user to recognize that the waterproof plate is operating abnormally. Note that this message can adopt any form such as e-mail or push transmission.

(Waterproof device monitoring method)

In order to explain the waterproof device monitoring method according to the present embodiment, the symbols shown in FIGS.

First, the monitoring process is started in step S01, and the process proceeds to step S02. In step S02, the control unit 42 determines the water level at the location where the waterproof board is installed. In this step, when the server 40 receives that the water level sensor 14 has changed from an OFF signal to an ON signal, S02, ON. S02, OFF unless the server 40 receives that the water level sensor 14 has changed from an OFF signal to an ON signal.

If S02 is OFF, the process proceeds to step S03. In step S03, the controller 42 determines the attitude of the waterproof plate. In this step, when the server 40 receives that the proximity sensor 13 has changed from an OFF signal to an ON signal, S03, ON. S03 is OFF unless the server 40 receives that the proximity sensor 13 has changed from an OFF signal to an ON signal.

The case of S03, OFF is a normal state in which the water level has not risen and the waterproof plate has not been erected. In this case, the process moves to step S04. In order to continue monitoring in step S04, the process returns to step S01 to continue monitoring.

The case of S03, ON is an abnormal state in which the waterproof plate is erected even though the water level has not risen. In this case, the process moves to step S05. In step S<b>05 , the control unit 42 transmits a message to the effect that the waterproof plate is operating abnormally from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . This allows the user to recognize that the waterproof plate is operating abnormally.

If step S02 is ON, that is, if the water level rises to a high level, the process proceeds to step S06. In step S06, the control unit 42 records in the storage unit 43 that the water level has changed to high. Then, the process moves to step S07.

In step S<b>07 , the control unit 42 transmits a message to the effect that the water level is rising from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . This allows the user to recognize that the water level is rising at the place where the waterproof board is installed. After the processing of step S07, the process proceeds to step S08.

In step S08, the controller 42 determines the attitude of the waterproof plate. In this step, when the server 40 receives that the proximity sensor 13 has changed from an OFF signal to an ON signal, S08, ON. S08 is OFF unless the server 40 receives that the proximity sensor 13 has changed from an OFF signal to an ON signal.

When S08 is ON, the water level rises and then the waterproof plate stands up, in which case the process proceeds to step S09. If S08 is OFF, the process proceeds to step S17.

In step S<b>09 , the control unit 42 records in the storage unit 43 that the waterproof plate has changed to the standing posture. Then, the process moves to step S10. In step S<b>10 , the control unit 42 transmits a message to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 from the communication unit 41 to the effect that the waterproof board will stand up as the water level rises. Thereby, the user can recognize that the water level at the place where the waterproof board is installed rises and the waterproof board stands up. After step S10, the process proceeds to step S11.

In step S11, the controller 42 determines the posture of the waterproof plate. In this step, when the server 40 receives that the proximity sensor 13 has changed from an ON signal to an OFF signal, S11, OFF. S11 is ON unless the server 40 receives that the proximity sensor 13 has changed from an ON signal to an OFF signal.

If S11 is ON, the water level remains high and the waterproof plate remains standing, in which case the process proceeds to step S12. In step S12, it waits until a predetermined time (X hours) has passed. This time can be set arbitrarily. Then, the process moves to step S13. In step S13, the control unit 42 records in the storage unit 43 that a message will be sent to the user in the next step and the contents of the transmission. Then, the process moves to step S14. In step S<b>14 , the control unit 42 transmits a message to the effect that the X-hour waterproof plate remains upright from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . This allows users to recognize the possibility that heavy rain has continued for a long time and the water level has not decreased and the waterproof board has been standing up, or that trouble has occurred such as a foreign object being caught in the waterproof board and preventing it from falling down. can. After the processing of step S14, the process returns to step S11.

If step S11 is OFF, that is, if the waterproof board falls down, the process proceeds to step S15. In step S<b>15 , the control unit 42 records in the storage unit 43 that the waterproof board has turned to the lying posture. Then, the process moves to step S16. In step S<b>16 , the control unit 42 transmits a message to the effect that the waterproof board has fallen down from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . This allows the user to recognize that the waterproof board has fallen normally. After the process of step S16, the process moves to step S17.

In step S17, the control unit 42 determines the water level at the location where the waterproof plate is installed. In this step, when the server 40 receives that the water level sensor 14 has changed from the ON signal to the OFF signal, S17, OFF. S17 is ON unless the server 40 receives that the water level sensor 14 has changed from an ON signal to an OFF signal.

The case of S17, ON means that the waterproof board is in the lying posture and the water level remains high, and in this case, the process proceeds to step S18. In step S18, it waits until a predetermined time (Y time) has passed. This time can be set arbitrarily. Then, the process moves to step S19. In step S19, the control unit 42 records in the storage unit 43 that a message will be sent to the user in the next step and the contents of the transmission. Then, the process moves to step S20. In step S<b>20 , the control unit 42 transmits a message indicating that the water level remains high for Y hours from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . This allows the user to recognize the possibility that an abnormality has occurred in the drainage at the location where the waterproof plate is installed, and prompts the user to check the drainage port 91c (see FIG. 1). After the process of step S20, the process returns to step S17.

If the step S17 is OFF, that is, if the waterproof plate is in the lying posture and the water level is low, the process moves to step S21. In step S21, the control unit 42 records in the storage unit 43 that the water level has turned to a low water level. Then, the process moves to step S22. In step S<b>22 , the control unit 42 transmits a message to the effect that the water level has decreased from the communication unit 41 to the mobile terminal 60 and/or the fixed terminal 70 via the communication network 30 . As a result, the user can recognize that the water level at the location where the waterproof plate is installed has decreased normally. After the process of step S22, the process moves to step S23, and a series of processes ends, and the process returns to step S01 for starting monitoring again.

(Modified example of waterproof device)
Next, modified examples of the waterproof device will be described using the reference numerals shown in FIGS. In the above-described embodiment, the non-contact proximity sensor 13 using magnetism is used as the waterproof plate attitude detection means for detecting the waterproof plate attitude, but a contact sensor is used as the waterproof plate attitude detection means. It is also possible to In the above-described embodiment, the waterproof plate attitude detection means is the proximity sensor 13 that outputs a binary value of ON or OFF. A sensor may be used. The angle detected by the angle sensor may be transmitted to the server 40, and the controller 42 may be configured to determine whether it is in the lying down posture or the standing posture. Further, the storage unit 43 can be configured to continuously record the angle as a numerical value.

In the above-described embodiment, the water level sensor 14 is used as the water level detection means for detecting the water level of the recess 91a in which the waterproof plate is installed. good too. It is also possible to transmit the detected water level to the server 40 and allow the controller 42 to determine whether the water level is low or high. Alternatively, the storage unit 43 may be configured to continuously record the water level as a numerical value.

Although the water level sensor 14 is arranged under the grating 95 in the above-described embodiment, the place of arrangement is not limited to this. The water level sensor 14 can also be arranged so that the upper end 14b is almost at the same height as the floor surface 91 and the top surface of the waterproof board 11 in the laid down posture so as to avoid the grating 95 being positioned on the water level sensor 14. It is possible. With this arrangement, when the water level rises to the height of the top surface of the waterproof plate 11 and the floor surface 91, an ON signal is output and it is determined that the water level is high.

In the above-described embodiment, the battery housed in the control box 15 is configured to supply power, but it is also possible to configure so that power is supplied from an external power source. In that case, instead of transmitting to the server 40 only when the proximity sensor 13 and the water level sensor 14 change from an OFF signal to an ON signal and vice versa, the proximity sensor 13 and the water level sensor 14 detect It is also possible to configure the value to be transmitted frequently (for example, at regular time intervals).

(Modified example of waterproof device monitoring system)
Next, a modified example of the waterproof device monitoring system will be described using the symbols shown in FIGS. Although the waterproof device monitoring system 100 according to the above-described embodiment is configured as a system that monitors one waterproof device 10, it is of course possible to configure a system that monitors a plurality of waterproof devices using one server 40. is. The message may then be sent to the user's mobile terminal 60 and/or fixed terminal 70 associated with each watertight device 10 . Thereby, one server 40 can monitor a plurality of waterproof devices. In addition, it becomes possible to collect information on a plurality of waterproof boards installed in various places at one place. The information collected in this way is effectively used for disaster prevention and mitigation.

(Modified example of waterproof device monitoring method)
Next, a modification of the waterproof device monitoring method will be described using the symbols shown in FIGS. In the waterproof device monitoring method according to the above-described embodiment, after the monitoring process starts in step S01, the process proceeds to step S02 to determine the water level. It can be configured to periodically (eg, once a day) send a signal to server 40 indicating that it is present. If the server 40 does not receive this signal, it can send a message to the user that the waterproof device 10 is not working properly. Thereby, the user can recognize the possibility that the battery of the control box 15 is dead or the possibility of communication failure via the antenna 16 .

It is also possible for the control unit 42 of the server 40 to change the message to be sent according to the attributes of the user (facility owner, waterproof board agent, etc.). It is also possible to select a destination user. Changing the message and selecting the destination user can be applied in any of steps S05, S07, S10, S14, S16, S20 and S22.

In addition, as described above, the waterproof device 10 has the water level sensor 14 arranged so that the water level lower than the water level at which the waterproof board 11 starts to stand due to buoyancy serves as the threshold for distinguishing between the low water level and the high water level. It is also possible to arrange the water level sensor 14 so that the water level at which the waterproof plate 11 begins to stand up due to buoyancy serves as a threshold for distinguishing between the low water level and the high water level. In this configuration, if the waterproof plate 11 operates normally, the proximity sensor 13 and the water level sensor 14 will turn from the OFF signal to the ON signal almost at the same time as the water level in the recess 91a rises.

In that configuration, if only the water level sensor 14 changes from an OFF signal to an ON signal and the proximity sensor 13 remains an OFF signal, the water level rises to the level at which the waterproof plate 11 should stand up. , suggests that the waterproof plate 11 is not upright. In that case, the possibility of rainwater flowing into the entrance/exit increases. Therefore, as a modification of the waterproof device monitoring method, when only the water level sensor 14 turns from an OFF signal to an ON signal and the proximity sensor 13 remains an OFF signal, the user is informed that the waterproof plate is not operating for some reason. can be configured to notify

In the waterproof device monitoring method described above, from step S08, ON to step S11, OFF, that is, while the proximity sensor 13 is outputting an ON signal and the waterproof board 11 is upright, the water level sensor 14 is ON. If the water level sensor 14 changes to an OFF signal during this period, that is, if the water level drops while the waterproof plate 11 remains upright, even if the water level drops, It is also possible to send a message to the user that the tarp will not fall down regardless.
