Description

Technical Field

[0001] The present invention relates to a technology of a notification system and a notification method for manhole pump facilities.

Background Art

[0002] Conventionally, technologies for managing a plurality of manhole pump facilities are known. For example, Patent Document 1 discloses a wireless communication system in which each of a plurality of manhole pump facilities scattered within a predetermined area is provided with a notification device capable of notifying information such as a failure of each facility. In the wireless communication system, when a control panel of a manhole pump facility detects an abnormality such as a power failure, event occurrence information indicating the occurrence of the abnormality is automatically notified to a management device via a wireless station having an automatic voice response function. According to the above configuration, voice notifications for each manhole pump facility can be individually made to the administrator.

[0003] When the system described in Patent Document 1 is used, it is assumed that when a power failure occurs within a predetermined area, individual voice notifications for each manhole pump facility within the predetermined area are made simultaneously. Therefore, the notifications may become complicated, and the burden on the administrator who receives the notifications may increase.

Modes for Carrying Out the Invention

[0021] Hereinafter, referring to FIGS. 1 and 2, a notification system 1 according to an embodiment of the present invention will be described. The notification system 1 monitors the operating status of the manhole pump facility 10 described later, and performs notification when an abnormality such as a power failure occurs in the manhole pump facility 10. The notification system 1 includes a manhole pump facility 10, a central monitoring device 20, an audio notification device 30, and a terminal 40.

[0022] The manhole pump facility 10 shown in FIG. 1 is a facility for sending sewage in the manhole 11 to a sewage treatment plant. The manhole pump facility 10 includes a manhole 11, a lid 12, an inflow pipe 13, an outflow pipe 14, a manhole pump 15, a water level gauge 16, and a control panel 17.

[0023] Manhole 11 is for managing the underground sewer system. Manhole 11 is installed at multiple locations in the sewer system. An opening is formed at the top of the manhole 11, allowing workers to enter and exit from the ground. The opening is provided with a lid 12 that can be opened and closed.

[0024] An inlet pipe 13 is connected to manhole 11 through which sewage flowing into manhole 11 flows. Sewage from the inlet pipe 13 is temporarily stored in manhole 11. The sewage in manhole 11 is discharged by a manhole pump 15, which will be described later. An outlet pipe 14 is connected to manhole 11 through which sewage discharged (leaved out) from manhole 11 flows. Sewage flowing through the sewer system is guided to the sewage treatment plant by sequentially passing through multiple manholes 11, inlet pipes 13 and outlet pipes 14.

[0025] The manhole pump 15 is used to discharge sewage from the manhole 11. The manhole pump 15 is connected to the outflow pipe 14. By operating the manhole pump 15 and discharging the sewage, the water level inside the manhole 11 can be lowered. In this embodiment, two manhole pumps 15 are installed in one manhole 11. Hereafter, the two manhole pumps 15 will be described as "first pump 15A" and "second pump 15B" as needed. The manhole pump 15 is operated by electricity supplied from the outside via a power distribution line.

[0026] The water level gauge 16 detects the water level inside the manhole 11. The water level gauge 16 is placed inside the manhole 11. For example, a submersible pressure type can be used as the water level gauge 16. However, the water level gauge 16 is not limited to the submersible pressure type; various devices capable of detecting water levels, such as bubble type or float type, can be used. In addition, multiple water level gauges 16 can be installed inside the manhole 11. For example, in addition to a submersible pressure type or bubble type water level gauge 16, a float type water level gauge 16 may be provided as a backup.

[0027] The control panel 17 controls the operation of the manhole pump 15 and sets its operation. The control panel 17 is installed on the ground near the manhole 11. The control panel 17 includes a control unit 18 and a notification unit 19.

[0028] The control unit 18 controls the operation of the manhole pump 15. The control unit 18 has a computing device (e.g., relay circuit, PLC, CPU, etc.) and a storage device (e.g., memory card, HDD, SSD, etc.). The control unit 18 operates on power supplied from an external source, such as a commercial power supply, or from an internal power supply installed inside the control panel 17. The control unit 18 is connected to the manhole pump 15 and the water level gauge 16 via appropriate communication lines. The control unit 18 can acquire water level information detected by the water level gauge 16 (hereinafter referred to as "water level information"). The control unit 18 can also acquire information indicating that the manhole pump 15 (first pump 15A and second pump 15B) has failed (hereinafter referred to as "pump failure information") and information indicating that the supply of external power has stopped due to a power outage (hereinafter referred to as "power outage information").

[0029] The control unit 18 can control the operation of the manhole pump 15 based on water level information. The operation of the manhole pump 15 will be described below with reference to Figure 1. The control unit 18 is set to stop water level L1, operating water level L2, and abnormally high water level L3, which are the water levels that serve as the reference for the operation of the manhole pump 15.

[0030] The stop water level L1 is the water level at which the operation of the manhole pump 15 is stopped. The operating water level L2 is a water level higher than the stop water level L1 and is the water level at which the operation of the manhole pump 15 is started. Here, the manhole pump equipment 10 is equipped with two manhole pumps 15 (first pump 15A and second pump 15B). For this reason, the control unit 18 is set to a water level at which the operation of one manhole pump 15 is started (single-pump operating water level) and a water level higher than the single-pump operating water level at which the operation of both manhole pumps 15 is started (double-pump operating water level). In the following explanation, the operating water level L2 will be referred to as the single-pump operating water level. The abnormally high water level L3 is a water level higher than the operating water level L2 and is the water level at which it is determined that the water level in the manhole 11 has become abnormally high. In the following explanation, the abnormally high water level L3 will be referred to as the double-pump operating water level.

[0031] The following describes an example of the operation of the manhole pump 15. This operating method is generally called the single-unit alternating emergency parallel operation method. When the control unit 18 acquires water level information for the operating water level L2 (water level information indicating that the water level in the manhole 11 has reached the operating water level L2), it starts operating one of the manhole pumps 15 (one of the first pump 15A and the second pump 15B). Subsequently, when the control unit 18 acquires water level information for the stop water level L1 (water level information indicating that the water level in the manhole 11 has reached the stop water level L1), it stops operating the manhole pump 15.

[0032] Furthermore, when the control unit 18 next acquires water level information for the operating water level L2, it starts the operation of the other manhole pump 15 (the other of the first pump 15A and the second pump 15B), and then stops the operation of the manhole pump 15 when it acquires water level information for the stop water level L1. The control unit 18 can repeatedly execute the above control to operate the first pump 15A and the second pump 15B alternately.

[0033] Furthermore, if the control unit 18 acquires the above-mentioned abnormally high water level L3 water level information (water level information indicating that the water level in the manhole 11 has reached the operating water level for both pumps), it can control the operation of both the first pump 15A and the second pump 15B simultaneously. Also, if the control unit 18 acquires pump failure information for one of the first pump 15A and the second pump 15B, it can control the operation of only the other manhole pump 15.

[0034] The notification unit 19 is capable of transmitting information acquired by the control unit 18 to external devices. In this embodiment, the notification unit 19 can notify the central monitoring device 20 of information (notification information) regarding abnormalities in the manhole pump equipment 10 acquired by the control unit 18. The notification unit 19 operates on power supplied from either an external commercial power source or an internal power source installed inside the control panel 17.

[0035] Here, the notification unit 19 is configured to transmit four pieces of information that can be reported. Specifically, the notification unit 19 is configured to transmit four signals as notification information: power outage information, pump failure information for the first pump 15A, pump failure information for the second pump 15B, and water level information indicating an abnormally high water level L3.

[0036] In addition to the control unit 18 and notification unit 19 mentioned above, the control panel 17 can be appropriately equipped with devices such as an operation panel that allows setting the operation of the manhole pump 15.

[0037] As shown in Figure 2, multiple manhole pump facilities 10 as described above are installed within a predetermined area. Here, a predetermined area refers to a specific area of ​​land (for example, land at the municipal level) that has been divided into multiple sections. In Figure 2, as an example of multiple manhole pump facilities 10, the first manhole pump facility 10Aa, the second manhole pump facility 10Ab, the third manhole pump facility 10Ac, the fourth manhole pump facility 10Ad, and the fifth manhole pump facility 10Ae are shown.

[0038] The central monitoring device 20 shown in Figures 1 and 2 monitors the operating status of multiple manhole pump facilities 10. The central monitoring device 20 includes a computing device, a storage device, and a communication device. The communication device is configured to communicate with each manhole pump facility 10, as well as the voice notification device 30 and terminal 40 described later, using a data communication line such as an internet connection.

[0039] The central monitoring device 20 can be a server, personal computer, smartphone, tablet terminal, or the like. In this embodiment, as an example, an example in which the central monitoring device 20 is a cloud server will be described.

[0040] The central monitoring device 20 can receive information transmitted from the notification unit 19 of each manhole pump equipment 10 via a communication device. The central monitoring device 20 can also create an email indicating the notification information received from the manhole pump equipment 10 and send it as an email via the communication device. As shown in Figure 2, the central monitoring device 20 can send the email to the voice notification device 30 and terminal 40, which will be described later. The central monitoring device 20 can also display the information received from the notification unit 19 and the contents of the email on a designated display unit such as a display screen.

[0041] The voice notification device 30 receives emails sent from the central monitoring device 20, converts the contents of the emails into voice information, and transmits the voice information. As shown in Figure 2, the voice notification device 30 can make voice notifications (voice notifications) by transmitting the voice information to the terminal 40, which will be described later. The voice notification device 30 according to this embodiment can make telephone notifications (telephone notifications) by making voice notifications using a telephone line. The voice notification device 30 has a computing device, a storage device, and a communication device. The voice notification device 30 can be a server, a personal computer, a smartphone, a tablet terminal, etc. As an example in this embodiment, an example in which the voice notification device 30 is a cloud server will be described. The voice notification device 30 has a filtering function that classifies emails based on the characters etc. contained in the received emails.

[0042] Terminal 40 is capable of receiving emails from the central monitoring device 20 and voice information from the voice notification device 30. A mobile phone such as a smartphone can be used as terminal 40. In this embodiment, the manager of the manhole pump equipment 10 and the workers who respond to abnormalities (power outages or malfunctions) of the manhole pump equipment 10 will have terminal 40. When a telephone notification is made by the voice notification device 30, terminal 40, which has received the voice information from the voice notification device 30, will notify the manager, etc. by emitting a ringtone. The manager, etc. can listen to the voice information by making a call to terminal 40.

[0043] The configuration of the notification system 1 according to this embodiment has been described above. The following describes the manner in which notifications are made by the notification system 1.

[0044] The notification system 1 can notify administrators and workers by sending voice messages or emails to terminals 40 in the event of an abnormality in the manhole pump equipment 10. Specifically, the notification system 1 will send voice messages or emails if any of the following occurs in the manhole pump equipment 10: a power outage, a malfunction of the manhole pump 15, or the water level in the manhole 11 reaches an abnormally high level L3.

[0045] Here, it is assumed that the power outage will occur over a certain area. For example, if a power outage occurs throughout an entire area, a power outage notification will be sent to all manhole pump equipment 10 located in that area. In this case, it is assumed that many voice notifications will be sent to the terminal 40 simultaneously. In this case, the notifications may become confused, potentially placing a heavy burden on the administrators who have the terminal 40. Also, with voice notifications being sent simultaneously, voice notifications for manhole pump equipment 10 that should be prioritized for power outage response, such as manhole pump equipment 10 with high water levels in the manhole 11, may be buried, potentially delaying the response to those manhole pump equipment 10. Furthermore, if power outage notifications for manhole pump equipment 10 are sent simultaneously, the communication lines used for the notification system 1 may become congested.

[0046] Therefore, the notification system 1 according to this embodiment is capable of performing "delayed voice notifications," which provide voice notifications with a time delay based on the water level of the manhole pump equipment 10. In the notification system 1 according to this embodiment, the notification unit 19 provides the above-mentioned time delay.

[0047] The operation of the notification unit 19 will be explained below using the time chart in Figure 3. The time chart above shows the relationship between the on / off transmission of power outage information, the on / off transmission of pump failure information for the manhole pumps 15 (first pump 15A and second pump 15B), and the water level information inside the manhole 11 (stopped water level L1 or abnormally high water level L3).

[0048] In Figure 3, the area X1 enclosed by the dashed line shows an example where no power outage occurs, but the manhole pump 15 (first pump 15A and second pump 15B) has failed. In this case, the control unit 18 acquires information about the failure of either the first pump 15A or the second pump 15B as notification information, and the notification unit 19 transmits the pump failure information. The transmission of the pump failure information is performed when the control unit 18 acquires the notification information (pump failure information).

[0049] Furthermore, ranges X2 and X3 in Figure 3 show an example of a power outage. When a power outage occurs, the power supply to the manhole pump 15 stops, and the operation of the manhole pump 15 stops. In this embodiment, the control unit 18 treats the state in which the manhole pump 15 cannot operate due to a power outage as a pump failure. Specifically, when the control unit 18 detects that the operation of the manhole pump 15 has stopped when a power outage occurs, it acquires pump failure information. For this reason, when a power outage occurs, the control unit 18 acquires both power outage information and pump failure information as notification information. The notification unit 19 also transmits the above notification information (power outage information and pump failure information).

[0050] In this embodiment, the notification unit 19 transmits the power outage information at the time the control unit 18 acquires the notification information (power outage information and pump failure information). The notification unit 19 can also transmit the pump failure information after a predetermined time difference (time difference T, described later) based on the water level information, from the time the notification information (power outage information and pump failure information) is acquired.

[0051] Specifically, as shown in area X2 of Figure 3, if the control unit 18 has acquired power outage information and has also acquired information on the abnormally high water level L3 (the water level in the manhole 11 has reached the abnormally high water level L3), the notification unit 19 will transmit pump failure information simultaneously with the power outage information (without any time delay).

[0052] On the other hand, as shown in area X3 of Figure 3, if the control unit 18 has acquired power outage information but has not acquired water level information for the abnormally high water level L3 (i.e., the water level in the manhole 11 has not reached the abnormally high water level L3), the notification unit 19 will transmit the pump failure information with a time delay T after transmitting the power outage information (acquisition of notification information (power outage information and pump failure information)). In other words, the notification unit 19 will wait to transmit the pump failure information until a time equivalent to the time delay T has elapsed from the transmission of the power outage information.

[0053] The above time difference T is set based on the ratio of the actual water level in the manhole 11 (the water level indicated by the water level information detected by the water level gauge 16) to the abnormally high water level L3. In this embodiment, the larger the ratio of the water level in the manhole 11 to the abnormally high water level L3, the shorter the time difference T is set. The notification unit 19 in this embodiment is equipped with a timer for setting the time difference T. The timer outputs pump failure information after a time corresponding to the water level in the manhole 11 has elapsed since the pump failure information was input (see the time difference T shown in the table in Figure 4). The timer is provided, for example, in the circuit of the notification unit 19.

[0054] The table in Figure 4 shows an example of the relationship between the ratio of the water level in the manhole 11 to the abnormally high water level L3 and the time difference T. As shown in the table above, in this embodiment, if the ratio of the water level in the manhole 11 to the abnormally high water level L3 is 0% or more and less than 10%, the time difference T is 10 minutes; if it is 10% or more and less than 20%, the time difference T is 9 minutes; if it is 20% or more and less than 30%, the time difference T is 8 minutes; if it is 30% or more and less than 40%, the time difference T is 7 minutes; if it is 40% or more and less than 50%, the time difference T is 6 minutes; if it is 50% or more and less than 60%, the time difference T is 4 minutes; if it is 60% or more and less than 70%, the time difference T is 3 minutes; if it is 80% or more and less than 90%, the time difference T is 2 minutes; if it is 90% or more and less than 100%, the time difference T is 1 minute; and if it is 100% or more, the time difference T is 0 minutes (no time difference T). Note that the contents of the table shown in Figure 4 are just an example, and various values ​​can be used for the time difference T.

[0055] Furthermore, if the ratio of the water level inside the manhole 11 to the abnormally high water level L3 is 100% or more (i.e., the water level has reached the abnormally high water level L3), it is preferable that the notification unit 19 transmits power outage information and pump failure information as notification information without a time delay T, as well as transmits water level information indicating the abnormally high water level L3.

[0056] The operation of the notification unit 19 has been explained above. According to the notification unit 19, power outage information and pump failure information can be transmitted with a time difference T corresponding to the ratio of the water level in the manhole 11 to the abnormally high water level L3. As a result, the party receiving the power outage information and pump failure information (notification information) can grasp the water level information of the manhole pump equipment 10 during the power outage (the ratio of the water level detected by the water level gauge 16 to the abnormally high water level L3) based on the time difference T. In this embodiment, even with the notification unit 19 which has limitations on the number of information points that can be transmitted, the water level in the manhole 11 can be shown in multiple stages.

[0057] The notification unit 19 transmits pump failure information with the above-mentioned time difference T, so that the closer the water level of the manhole pump equipment 10 is to the abnormally high water level L3, the earlier the notification can be sent. In other words, according to this implementation, notification information from manhole pump equipment 10 with a water level close to the abnormally high water level L3 can be sent to the central monitoring device 20 as a priority.

[0058] The operation of the central monitoring device 20 and the voice notification device 30 will be explained below using Figures 1 and 2. The central monitoring device 20 receives notification information transmitted from the notification unit 19 and creates an email based on the received notification information. As described above, if a power outage occurs in the manhole pump equipment 10, the notification unit 19 first transmits power outage information as notification information, and then transmits pump failure information after a time difference T. Therefore, the central monitoring device 20 receives the pump failure information after receiving the power outage information and after a time difference T. When the central monitoring device 20 receives both the power outage information and the pump failure information, it creates an email based on the received information and transmits the email to the voice notification device 30 and the terminal 40.

[0059] The above email is created for each manhole pump facility 10. The above email contains details of the abnormality that occurred in the manhole pump facility 10. The central monitoring device 20 records the above time difference T and can also include information about the time difference T in the above email. In addition, the email can contain various information related to the abnormality, such as the date and time of the abnormality, information that identifies the manhole pump facility 10 in which the abnormality occurred, and information about the area in which the manhole pump facility 10 is installed.

[0060] The voice notification device 30 receives an email sent from the central monitoring device 20 and converts the email into voice information. The voice notification device 30 then sends the voice information to the terminal 40 to make a voice notification. The conversion of the voice information and the voice notification are performed when the email from the central monitoring device 20 is received.

[0061] Administrators and other personnel with terminal 40 can receive the above voice notification as a telephone notification. Administrators and other personnel can also check the emails received by terminal 40. Making a telephone notification as described above ensures more reliable notification than sending only an email.

[0062] The notification system 1 described above can make telephone notifications at a timing corresponding to the time difference T, by providing a time difference T between when the control unit 18 acquires power outage information (pump failure information acquired simultaneously with the power outage information) and when the voice notification device 30 transmits a telephone notification. In other words, in this embodiment, when a power outage occurs in the manhole pump equipment 10, the notification unit 19 transmits the power outage information at the time the control unit 18 acquires the notification information (power outage information and pump failure information), and then transmits the pump failure information after a time difference T. The central monitoring device 20 sends an email at the time it receives the notification information (both power outage information and pump failure information) from the notification unit 19, and the voice notification device 30 makes a telephone notification at the time it receives the email. This makes it possible to suppress simultaneous telephone notifications. In addition, telephone notifications can be prioritized for manhole pump equipment 10 whose water level is close to an abnormally high water level. This makes it possible to suppress delays in responding to manhole pump equipment 10, for which it is desirable to prioritize responding to power outages. Furthermore, administrators who receive the email notification can grasp the water level of the manhole pump equipment 10 from the time difference T.

[0063] In this case, for example, in a manhole pump facility 10 where the priority of response (water level relative to abnormally high water level) is relatively low and the time difference T is relatively long, the power outage may be restored while the notification unit 19 is waiting to transmit pump failure information. In such cases, the central monitoring device 20 according to this embodiment can stop sending notifications by email. This reduces unnecessary notifications by email, and consequently reduces unnecessary voice notifications.

[0064] The above describes the methods of reporting using the reporting system 1. Note that the methods of reporting using the reporting system 1 are not limited to the examples described above and can be modified as appropriate. Furthermore, the specific numerical values ​​exemplified in the above explanation are examples only and can be changed at will.

[0065] For example, in the notification system 1 described above, a configuration is described in which the central monitoring device 20 records the time difference T. However, in addition to recording the time difference T, a configuration can also be adopted in which a value indicating the water level of the manhole pump equipment 10 (for example, the ratio of the water level of the manhole 11 to the abnormally high water level L3) is calculated based on the time difference T. The above calculation can be performed by the central monitoring device 20 based on the table shown in Figure 4. In this case, the central monitoring device 20 can include the value indicating the water level of the manhole pump equipment 10 in the email. Alternatively, instead of the central monitoring device 20 performing the above calculation, a configuration can also be adopted in which the voice notification device 30 performs the calculation.

[0066] Furthermore, in the notification system 1, the filtering function of the voice notification device 30 can be used to omit the conversion of some of the voice information in the received emails. For example, the voice notification device 30 can omit the conversion of some of the voice information in emails concerning manhole pump equipment 10 with relatively low water levels. In this case, the voice notification device 30 can determine the water level of the manhole pump equipment 10 based on the time difference T information contained in the email, and omit notifications for manhole pump equipment 10 whose water level is lower than a predetermined threshold.

[0067] Furthermore, while the notification system 1 described above shows an example in which a time difference T is provided in the notification unit 19, it is not limited to this configuration. For example, it is also possible to provide a time difference T in the central monitoring device 20. In this case, the notification unit 19 transmits information regarding the time difference T (for example, information indicating the time difference T, or information regarding the ratio of water level information to the abnormally high water level L3) as notification information to the central monitoring device 20. The information regarding the time difference T can be transmitted as analog information, for example. In this case, the central monitoring device 20 can provide a time difference T between acquiring the notification information and sending the email to the voice notification device 30.

[0068] Alternatively, instead of providing a time difference T in the central monitoring device 20, it is also possible to provide a time difference T in the voice notification device 30. In this case, the voice notification device 30 can provide a time difference T between receiving the email and sending the voice notification.

[0069] Furthermore, the above example shows an example where a time difference T is introduced in the transmission of notification information from the notification unit 19 to the central monitoring device 20 (between the transmission of power outage information and the transmission of pump failure information), but the system is not limited to the above configuration. For example, instead of the notification unit 19 actually introducing a time difference T when transmitting the information, it is also possible to adopt a configuration in which notification information including "information indicating a time difference T (time difference information)" is transmitted to the central monitoring device 20. In this case, instead of the notification unit 19 introducing a time difference T, the central monitoring device 20 or the voice notification device 30 that receives the notification information from the notification unit 19 introduces a time difference T based on the time difference information when sending an email or voice notification. With the above configuration, the central monitoring device 20 does not need to process the time difference in the timing of receiving power outage information and pump failure information, and the computational load on the central monitoring device 20 can be reduced.

[0070] In this case, the central monitoring device 20 or voice notification device 30, which is the recipient of the notification information, can be configured to convert the time-delay information into water level information and transmit it to the terminal 40. With the above configuration, the water level information can be shown to the administrator who receives the notification, thereby informing them of the water level of the manhole pump equipment 10. Alternatively, the central monitoring device 20 or voice notification device 30 can be configured to transmit the time-delay information directly to the terminal 40. In this case, the administrator can intuitively understand when the power outage occurred and what the water level situation of the manhole pump equipment 10 is by checking the time-delay information.

[0071] As described above, the notification system 1 according to this embodiment is A notification system 1 that can report information about manhole pump equipment 10, A control unit 18 (power outage information acquisition unit) acquires power outage information indicating that a power outage has occurred in the manhole pump equipment 10, A control unit 18 (water level information acquisition unit) that acquires water level information related to the water level of the manhole pump equipment 10, The notification unit 19, central monitoring device 20, and voice notification device 30 (control unit) are capable of sending notifications (voice notifications, email notifications) to terminal 40 (notification target), and are capable of controlling a time difference T based on the water level information acquired by the control unit 18 (water level information acquisition unit) between the acquisition of the power outage information by the control unit 18 (power outage information acquisition unit) and the notification, It is equipped with the following features. This configuration helps to suppress the confusion of notifications. Specifically, by creating a time lag T based on water level information between the acquisition of notification information and the notification to terminal 40 (voice notification, email notification), it is possible to suppress simultaneous notifications during a power outage, thereby suppressing the confusion of power outage notifications. Furthermore, this allows those who receive the notification to understand the water level of the manhole pump equipment 10 from the time lag T.

[0072] Furthermore, the control unit, It is possible to transmit voice information that includes at least the aforementioned power outage information. The notification is performed by transmitting the aforementioned audio information. By configuring the system in this way, it is possible to suppress the simultaneous transmission of voice information during a power outage, thereby reducing the confusion of voice information during a power outage.

[0073] Furthermore, the control unit, A notification unit 19 capable of transmitting notification information including at least the aforementioned power outage information, The aforementioned notification information is transmitted as voice information by a voice notification device 30 (voice notification unit), It is equipped with, The aforementioned notification unit 19 is, The time difference T is established depending on the timing of the transmission of the notification information. By configuring it in this way, a time difference T can be created using a notification unit 19, which is provided for each manhole pump facility 10 and which notifies the recipient of power outage information.

[0074] Furthermore, the notification information includes pump failure information indicating a malfunction of the manhole pump 15 installed in the manhole pump equipment 10. The aforementioned notification unit 19 is, When the control unit 18 (power outage information acquisition unit) acquires the power outage information, it transmits the power outage information, and transmits the pump failure information after a time difference T has elapsed since the transmission of the power outage information. This configuration simplifies the structure of the notification system 1. Specifically, a time difference T can be introduced by changing the timing of transmission of power outage information and pump failure information by the notification unit 19. In this way, by using the notification unit 19 for reporting abnormalities in the manhole pump equipment 10 to introduce a time difference T, the notification system 1 can be configured without providing a separate device for introducing the time difference T.

[0075] Furthermore, the control unit, A notification unit 19 capable of transmitting notification information including at least the aforementioned power outage information, A central monitoring device 20 (email notification unit) is capable of acquiring the notification information transmitted by the notification unit 19 and sending the notification information as an email, A voice notification device 30 capable of receiving the email transmitted by the central monitoring device 20 and transmitting the email as voice information, It is equipped with, The central monitoring device 20 is The time difference T is established based on the timing of sending the aforementioned email. By configuring it in this way, a time difference T can be established using a central monitoring device 20 that can send notification information as an email.

[0076] Furthermore, the control unit, A notification unit 19 capable of transmitting notification information including at least the aforementioned power outage information, A central monitoring device 20 capable of acquiring the notification information transmitted by the notification unit 19 and transmitting the notification information as an email, A voice notification device 30 capable of receiving the email transmitted by the central monitoring device 20 and transmitting the email as voice information, It is equipped with, The aforementioned voice notification device 30 is The time difference T is provided depending on the timing of the transmission of the aforementioned audio information. By configuring it in this way, a time difference T can be provided using the voice notification device 30, which is capable of transmitting voice information.

[0077] Furthermore, the time difference T is, The setting is such that the ratio of the water level information to the pre-set abnormally high water level L3 (predetermined water level) becomes shorter as the ratio increases. By configuring it in this way, it is possible to prioritize the delivery of voice notifications to manhole pump equipment 10 with a high water level.

[0078] Furthermore, the reporting method according to this embodiment is A notification method that can provide information about manhole pump equipment 10, A power outage information acquisition step, which acquires power outage information indicating that a power outage has occurred in the manhole pump equipment 10, A water level information acquisition step for acquiring water level information related to the water level of the manhole pump equipment 10, It is possible to perform notification to the target of notification, and a time difference control step is performed to set a time difference T based on the water level information acquired in the water level information acquisition step between the acquisition of the power outage information in the power outage information acquisition step and the notification, It is equipped with the following features. By configuring it in this way, it is possible to suppress the simultaneous sending of notifications during a power outage.

[0079] Furthermore, the reporting method according to this embodiment is A notification method that can provide information about manhole pump equipment 10, A pump failure information acquisition step, which acquires pump failure information indicating that a pump failure has occurred in the manhole pump equipment 10 due to a power outage, A water level information acquisition step for acquiring water level information related to the water level of the manhole pump equipment 10, The system enables notification to be sent to the target of notification, and includes a time difference control step that provides a time difference T based on the water level information obtained in the water level information acquisition step between the acquisition of the pump failure information in the pump failure information acquisition step and the notification, It is equipped with the following features. This configuration helps to suppress the simultaneous issuance of notifications during a power outage. Furthermore, with the above configuration, it is possible to suppress the simultaneous issuance of notifications when a pump failure occurs in multiple manhole pump facilities 10, regardless of whether there is a power outage.

[0080] Furthermore, the reporting method according to this embodiment is The notification is performed by transmitting the water level information acquired in the water level information acquisition step, or by transmitting time difference information indicating the time difference T provided in the time difference control step.

[0081] Furthermore, in the notification method according to this embodiment, The aforementioned notification is, This is performed by transmitting voice information. By configuring it in this way, it is possible to suppress the simultaneous broadcasting of voice information during a power outage.

[0082] Furthermore, the notification method according to this embodiment includes the water level information as the notification information. By configuring it in this way, it is possible to inform the target recipient of water level information about the manhole pump equipment.

[0083] Furthermore, the control unit 18 according to this embodiment is one form of implementation of the power outage information acquisition unit and the water level information acquisition unit according to the present invention. Furthermore, the notification unit 19, central monitoring device 20, and voice notification device 30 according to this embodiment are one form of the control unit according to the present invention. Furthermore, the central monitoring device 20 according to this embodiment is one form of implementing the email notification unit according to the present invention.

[0085] For example, in the notification system 1 according to this embodiment, an example is shown in which notification is made to administrators etc. with terminals 40 by voice notification from voice notification device 30, but the system is not limited to this configuration. For example, it is also possible to make notifications by email notification from central monitoring device 20 without providing voice notification device 30. Even if the above configuration is adopted, since email is sent to terminals 40 at a timing corresponding to the time difference T, it is possible to suppress simultaneous email notifications during a power outage and suppress the confusion of power outage notifications. It should be noted that the above notification is not limited to voice notification or email notification, and various means of notification can be adopted.

[0086] In this embodiment, an example is shown in which a single-unit alternating emergency parallel operation method is adopted as the operating method for the manhole pump 15, but the embodiment is not limited to this configuration.
