Description

Embodiments of the present invention relate to a river information system, a river information providing system, and a method for delivering alarms regarding river information.

The River Information System is a system in which river offices, which are local agencies of the Ministry of Land, Infrastructure, Transport and Tourism, and local governments such as prefectures and other prefectures monitor and manage river water level information in real time, primarily for the purpose of flood control. The River Information System collects observation data such as rainfall and river water levels from observation stations at various locations using a telemetry system. In recent years, data collected by the River Information System has been made available to the general public via browsers, increasing awareness among the general public.

The river information system has an alarm email notification function. With this function, if the rainfall or water level published on the river information system exceeds a standard value, an alarm email is automatically sent out to alert users. In addition to a warning message, the alarm email includes information such as meteorological warnings issued by the Japan Meteorological Agency (heavy rain warnings, advisories, etc.) and dam release notifications. Users to whom alarm emails are sent include administrators of the river information system, local government officials, firefighting personnel, and general residents. Alarm emails are used to make decisions about disaster prevention systems and preparations for evacuation, so not only the content of the alarm email but also the decision to notify or not notify itself is important.

Patent No. 6257987 Patent No. 5871780 JP 2002-350559 A

Alarm emails are sent based on observation data such as rainfall and water levels. However, abnormal values may occur in the observation data due to malfunctions of observation equipment or incorrect operation during inspection work. Abnormal values refer to excessive precipitation or river water levels that exceed standard values. When an alarm email is sent due to an abnormal value, erroneous information is notified to an unspecified number of people, forcing administrators to do a great deal of work, such as sending emails to correct the information as soon as possible. Abnormal values do not necessarily occur during working hours, so administrators are required to respond regardless of day or night.

If false information is frequently notified, the reliability of the information will be called into question in the first place. This could result in fewer users of the alarm emails, or emails that are received but not used, leading to delayed responses even when a real dangerous situation occurs. Even when abnormal values occur, it is necessary to minimize false information notifications as much as possible.

The objective is to provide a river information system, a river information provision system, and a river information alarm distribution method that prevent the notification of erroneous information due to abnormal values.

The river information providing system of the embodiment is applicable to a river information system that acquires observation data from a telemetry system and distributes an alarm email when the observation data exceeds a predetermined threshold. The river information providing system includes an observation data control unit, a mode setting unit, and an email distribution unit. The observation data control unit receives observation data from the telemetry system. The mode setting unit selects either a notification mode in which an alarm email is sent when the observation data exceeds a reference value, or a non-notification mode in which no alarm email is sent, or selects either an automatic determination mode in which the notification mode and non-notification mode are automatically switched based on a predefined determination criterion, or a manual determination mode in which the switching is performed manually. When the notification mode is selected, the email distribution unit creates an alarm email when the observation data exceeds a reference value, and distributes the alarm email via a communication network.

The present embodiment of the present invention will be described in detail below.
The river information system is a system that collects observation data such as rainfall, water level, and dam quantities measured by telemetering and dam systems in real time, and provides the collected observation data to river managers (staff, etc.), flood prevention personnel, and local residents. The following explanation assumes application to disaster prevention systems for local governments, such as prefectures and cities, towns, and villages.

FIG. 1 is a diagram showing an example of a river information system according to an embodiment.
1, the river information system 1 comprises a river information providing system 2, a telemetry system 3 that collects observation data on river conditions, a radar rain gauge system 4, and a weather warning and advisory issuing system 5 as a public institution, all of which are connected to the river information providing system 2 via a dedicated line network 60. The river information system 1 is a system in which the river information providing system 2 collects and processes various data collected by the telemetry system 3, and the data is used for updating web pages, creating and distributing alarm emails, etc.

In FIG. 1, the telemetry system 3 includes a plurality of observation stations 120 to 12 n that acquire observation data relating to the state of rivers, and a master station 50 .
The observation stations 120 to 12n are installed, for example, along a river and include a water level sensor that observes the water level of the river and acquires water level data.
The master station 50 periodically (eg, at 10 minute intervals) collects the observation data acquired individually by the observation stations 120 to 12 n via the wireless communication network 40 and passes it to the communication processing server 20 of the river information providing system 2 .

The radar rain gauge system 4 is managed by, for example, the Ministry of Land, Infrastructure, Transport and Tourism, and acquires wide-area rainfall data using a weather radar.
The weather warning/advisory issuance system 5 is managed by, for example, the Japan Meteorological Agency, and issues weather warnings or weather advisories for predetermined regions (prefectures, cities, towns, and villages) according to the weather in each region.

The river information system 1 is a system that includes an alarm mail server 10 and a communication processing server 20. The alarm mail server 10 and the communication processing server 20 can communicate with each other, for example, via a LAN (Local Area Network). Furthermore, an operation terminal 30 is connected to the communication processing server 20, for example, via the LAN. The river information system 1 is installed, for example, in a prefectural office building.

The communication processing server 20 is connected to the radar rain gauge system 4 and the weather warning and advisory issuance system 5 as a public institution via a dedicated line network 60. The communication processing server 20 acquires rainfall data observed by the radar rain gauge system 4 and weather alerts issued by the weather warning and advisory issuance system 5 via the dedicated line network 60.
The operation terminal 30 has a function of providing various settings and operations to the communication processing server 20 .

The alarm mail server 10 is a server that creates alarm mail based on observation data on the state of rivers collected by the communication processing server 20 via the telemetry system 3. The alarm mail sent from the alarm mail server 10 is distributed to a user device 15, for example, via the Internet 70. The user device 15 is a terminal device (smartphone, laptop, etc.) owned by local government officials, flood prevention personnel, local residents, etc.

FIG. 2 is a functional block diagram showing an example of the communication processing server 20.
The communication processing server 20 is a computer including a processor 22, a memory 23, an interface unit (I/F) 21, and a storage 24 such as an HDD or SSD.

The interface unit 21 is an interface unit that is connected to the LAN leading to the alarm mail server 10, the parent station 50 of the telemetry system 3, and the dedicated line network 60.

The memory 23 is a storage unit that stores an automatic/manual flag 23a, a river water level DB 23b, a rainfall DB 23c, a reference water level DB 23d, and a weather warning/alert DB 23e.

The automatic/manual flag 23a of the memory 23 is a storage unit that stores the value indicating whether the mode is manual determination mode or automatic determination mode.

The river water level DB 23b is a storage unit that stores observation data (river water level).
The rainfall DB 23c is a storage unit that stores observation data (rainfall) in association with the name of an observation station and the observation time. The rainfall observation data can be acquired from the telemetry system 3 or a radar rain gauge system.
The reference water level DB 23d is a database that stores the names of rivers to be observed, the names of water level observation stations installed in the rivers, and the reference water level values for each observation station.
The weather warning/alert DB 23e is a storage unit that stores whether or not an alert has been issued.

Next, the processor 22 is a processing unit that includes an observation data control unit 22a and a mode setting unit 22b as processing functions related to the embodiment.

The observation data control unit 22a is a processing unit that acquires observation data related to river water levels and rainfall, as well as information on the issuance of weather warnings and advisories, and stores them in the memory 23.

First, regarding water level data, the observation data control unit 22a receives observation data on the river water level from the telemetry system 3 and controls the storage of the data in the river water level DB 23b in the memory 23. At this time, the acquired observation information on the water level is compared with the reference water level DB 23d, and any observation data that exceeds the reference value is flagged as exceeding the reference value and stored in the river water level DB 23b.

As for rainfall data, the observation data control unit 22 a receives the rainfall data from the radar rain gauge system 4 and controls the storage of the data in the rainfall DB 23 c of the memory 23 .
Furthermore, the observation data control unit 22a acquires information on the issuance/termination of weather warnings and advisories from the weather warning/advisory issuance system 5, and performs control to update the weather warning/advisory DB 23e.
The observation data on water levels and rainfall stored in the memory 23 is transferred to the alarm mail server 10 .

The mode setting unit 22b is a setting unit for selectively specifying either the manual determination mode or the automatic determination mode, and selectively specifying either the notification mode or the non-notification mode. In other words, the mode setting unit 22b is a control unit that determines the notification/non-notification mode and notifies the alarm mail server 10 of the result.

The mode setting unit 22b also displays the current mode on the display unit of the operation terminal 30. When a change input to change the automatic/manual determination mode is received from the operation terminal 30, the mode setting unit 22b updates the automatic/manual flag 23a.

In the manual determination mode, the mode setting unit 22 b determines the notification/non-notification mode based on the operation of the operation terminal 30 , and transmits a mode setting signal to the alarm mail server 10 .
On the other hand, in the automatic determination mode, the mode setting unit 22b checks whether or not a warning or alert has been announced. If it is (announced), the mode setting unit 22b determines that an alarm mail notification is necessary, and transmits a mode setting signal to the alarm mail server 10 to set the notification mode. If it is (not announced), the mode setting unit 22b determines that an alarm mail notification is unnecessary, and transmits a mode setting signal to the alarm mail server 10 to set the non-notification mode.

Here, the mode is switched, for example, from a display screen displayed on the display of the operation terminal 30. Depending on the input from the operation terminal 30, whether the mode is manual determination mode or automatic determination mode is stored by updating the value of the automatic/manual flag 23a in the memory.

Here, we will explain the mode that determines whether or not to send an alarm email. There are two modes: notification mode and non-notification mode.

First, the notification mode is a mode in which, when the observed river water level or rainfall exceeds a threshold, an alarm email is sent to a specified recipient to notify the user of this event.

In contrast, the non-notification mode is a mode in which alarm emails are not sent when they occur. In this mode, no alarm emails are sent even if the observed river water level or rainfall exceeds the threshold.

In addition, there are two modes to determine how to switch between notification mode and non-notification mode: manual determination mode and automatic determination mode.

Manual determination mode is a mode in which the administrator is responsible for switching between notification mode and non-notification mode. In manual determination mode, the operation terminal 30 displays whether the current mode is notification mode or non-notification mode, and allows input to change. For example, a large number of abnormal values may occur during system maintenance and inspection. In such a case, the system can be set to manual determination mode in advance and switched to non-notification mode to prevent the generation of alarm mail. In manual determination mode, the system determines notification/non-notification mode according to the operation of the administrator from the operation terminal 30, and sends a mode setting signal to the alarm mail server, which is the mail delivery unit 12b (Figure 3). When the system is in notification mode, an alarm mail is delivered from the mail delivery unit 12b (Figure 3).

The automatic determination mode is a mode in which the notification mode and non-notification mode are automatically switched based on a preset determination criterion. One example of the preset determination criterion is "switch to notification mode when a weather alert is issued by a public institution." Note that in the automatic determination mode, the operation terminal 30 cannot switch between notification mode and non-notification mode. If you wish to switch, you must first switch from automatic mode to manual mode, and then switch between notification mode and non-notification mode.

In automatic determination mode, the system checks whether an alert or warning has been issued, and if an alert has been issued, it determines that an email notification is necessary and sends a mode setting signal to the alarm mail server to set it to notification mode. On the other hand, if no alert has been issued, it determines that an email notification is not necessary and sends a mode setting signal to the alarm mail server to set it to non-notification mode.

It should be noted that the criteria in the automatic determination mode are not limited to this.
For example, the criterion may be "when the first observation data exceeds a reference value and the second observation data observed in the municipality that observed the first observation data exceeds the reference value, the notification mode is set." For example, when the reference value is exceeded at multiple water level observation stations in a prefecture, or when the reference value is exceeded at multiple rainfall observation stations in a prefecture, etc.

Alternatively, the criterion may be "switch to notification mode when the number of accesses per hour to a web page that publishes the status of rivers exceeds a preset number." For example, the criterion may be to switch to notification mode when the frequency of page views of a portal site for a local government's river information system exceeds a preset value.

Figure 3 is a functional block diagram showing an example of an alarm mail server 10. The alarm mail server 10 is a computer that includes a processor 12, a memory 13, an interface unit (I/F) 11, and a storage 14 such as a hard disk drive (HDD) or a solid state drive (SSD).

The interface unit 11 is an interface unit that is connected to the Internet 70 and a LAN that leads to the communication processing server 20.

The memory 13 is a storage unit that stores a notification/non-notification flag 13a, a destination list 13b, and a reference rainfall DB 13d.

Here, the notification/non-notification flag 13a is a flag for storing a value indicating whether the mode is a notification mode or a non-notification mode.
The destination list 13b is a list in which email addresses to which alarm emails are to be sent are registered.
The reference rainfall DB 13d is a database that stores the names of rainfall observation stations and the reference rainfall values for each observation station.

The processor 12 is a processing unit that includes a notification mode setting acceptance unit 12a and a mail delivery unit 12b as processing functions according to the embodiment.
The notification mode setting reception unit 12a receives a setting for either a notification mode in which an alarm mail is delivered, or a non-notification mode in which an alarm mail is not delivered. Switching between the notification mode and the non-notification mode is automatically performed by a mode setting signal from the mode setting unit 22b of the communication processing server 20. In the following description, "notification" of mail means delivering mail, and "non-notification" of mail is explained as being synonymous with not delivering mail.

The mail delivery unit 12b is a control unit that delivers an alarm mail via the Internet 70 as a communication network when the observation data exceeds a reference value in the notification mode. That is, when the mail delivery unit 12b receives the observation data, it refers to the notification/non-notification flag 13a and
Do not send alarm emails in silent mode.

On the other hand, in the notification mode, the mail delivery unit 12b judges whether the observation data exceeds the respective reference values (threshold values). Specifically, for observation data related to water level data, the presence or absence of a reference value exceedance flag added by the communication control server 20 is used to judge whether the reference value is exceeded. For rainfall data, the observation information related to rainfall received from the communication control server 20 is compared with the reference rainfall DB 13c to judge whether the reference value is exceeded. Here, the comparison of rainfall data with the reference value is described as being performed on the alarm server 10 side, but the reference value comparison may also be performed by the communication control server 20. In this case, this can be achieved by moving the reference rainfall DB 13c to the communication control server 20 and configuring it.

Here, if the observation data does not exceed the reference value, the mail delivery unit 12b does not deliver an alarm mail. On the other hand, if the observation data exceeds the reference value, the mail delivery unit 12b sends an alarm mail to a destination registered in advance in the destination list 13b.

[Regarding mode setting operation from the operation terminal 30]
Fig. 4 is a diagram showing an example of a web page displayed on the display of the operation terminal 30. Fig. 4 shows an example of an administrator-only screen of the river information system, and includes a [Notification setting] button 80 and a notification mode icon 90 indicating the notification mode/non-notification mode of the alarm mail.

Figure 5 is a diagram showing an example of the screen of the operation terminal 30 in non-notification mode. In Figure 5, the notification mode icon 90 is an email mark with a no-entry mark superimposed on it, clearly indicating that the device is currently in non-notification mode. When the operator clicks the [Notification settings] button 80 here, the notification settings screen in Figure 6 is opened.

Fig. 6 is a diagram showing an example of a notification setting screen. This operation screen has an operation area (1. Automatic/Manual Determination Switch) for switching between automatic determination mode and manual determination mode, and an operation area (2. Email Notification/Non-Notification Switch) for switching between alarm email notification mode and non-notification mode. Either mode can be selected using a radio button. Fig. 6 shows an example of a display when the current mode is automatic determination mode and non-notification mode.
When the radio button for specifying the manual determination mode and the radio button for specifying the notification mode are clicked in the state shown in FIG. 6, the state shown in FIG. 7 is obtained.

Figure 7 shows an example of an operation screen for individually specifying the manual determination mode and the notification mode. When the registration button is clicked in Figure 7, the window in Figure 8 opens.

Figure 8 shows an example of a "verify window" for reflecting the administrator's operations. When [OK] is clicked in the window in Figure 8, the setting contents are notified from the operation terminal 30 to the communication processing server 20, and are reflected in the internal processing.

Fig. 9 is a diagram showing an example of the operation terminal 30 in the notification mode. Compared to Fig. 5, the road-blocking mark has been removed from the email mark, making it clear that the notification mode has been entered. Furthermore, when the administrator clicks the [Notification Settings] button 80, an operation screen similar to that in Fig. 6 is opened, and the settings can be changed.
When the notification mode is activated, the created alarm email is sent immediately.

As in Figure 6, the current setting status is shown in the (1. Automatic/Manual Determination Switch) and (2. Email Notification/Hide Notification Switch) columns, and you can change the setting by clicking the radio button for each.

Figure 10 is a diagram showing another example of the operation screen on the operation terminal 30. Figure 10 shows the state in which the automatic determination mode radio button is clicked from the manual determination mode/notification mode (corresponding to Figure 9). When the [Register] button is then clicked, the verify window of Figure 8 opens again, and the [OK] button is pressed to switch to the automatic determination mode.

On the other hand, when the automatic determination mode is selected and the [Notification Settings] button 80 in FIG. 5 is clicked, the notification settings screen in FIG. 11 is opened.

Figure 11 shows an example of the operation screen when in automatic determination mode and non-notification mode. In automatic determination mode, the decision to switch between notification mode and non-notification mode is made automatically based on predefined determination criteria. Therefore, the mode will be either notification mode or non-notification mode depending on the situation at the time. Figure 11 shows that the mode is non-notification mode.

Next, the operation of the above configuration will be described.
FIG. 12 is a flowchart showing an example of a processing procedure related to mode setting in the communication processing server 20.

The communication processing server 20 refers to the automatic/manual flag 23a in the memory 23 (Figure 2) and determines whether the current mode is the automatic determination mode or the manual determination mode (step S11).

If it is in automatic determination mode, it is determined whether or not the predetermined determination criteria are met. As a specific example, the communication processing server 20 determines whether or not a weather warning has been issued at the current time based on information obtained from the dedicated line network 60 (step S12). As mentioned above, the predetermined determination criteria here are not limited to this. In the following explanation, the predetermined determination criteria will be used as an example of whether or not a weather advisory has been issued.

If a weather alert has been announced, the communication processing server 20 sends a mode setting signal to the alarm mail server 10 to set it to notification mode (step S14).

If no weather warning has been announced, the communication processing server 20 transmits a mode setting signal to the alarm mail server 10 to set the server to the non-notification mode (step S15).
The set mode is also notified to the operation terminal 30 and is reflected in the display content of the Web page (FIGS. 5 and 9).

On the other hand, if the manual determination mode is selected in step S11, the communication processing server 20 determines whether the administrator's designation via a web screen operation on the operation terminal 30 is notification mode or non-notification mode (step S13).

If the notification mode is specified on the operation terminal 30, the communication processing server 20 transmits a mode setting signal to the alarm mail server 10 to set it to the notification mode (step S16). On the other hand, if the non-notification mode is specified on the operation terminal 30, the communication processing server 20 transmits a mode setting signal to the alarm mail server 10 to set it to the non-notification mode (step S17).

The alarm mail server 10, which receives an instruction from the communication processing server 20, stores the notification mode/non-notification mode specified by the communication processing server 20 as the value of the notification/non-notification flag 13a in the memory 13 (Figure 3) within the alarm mail server 10.

In this way, when the notification/non-notification flag is set in the alarm mail server 10, the observation data control unit 22a of the communication processing server 20 acquires observation data via the telemeter at a predetermined time interval and stores the observation data in the river water level DB 23b and the rainfall DB 23c. In addition, the rainfall data acquired from the radar rain gauge system is also stored in the rainfall DB 23c. Furthermore, the presence or absence of an advisory warning is also acquired and stored in the weather warning/advisory DB. Furthermore, the observation data control unit 22a transfers the observation data stored in the river water level DB 23b and the rainfall DB 23c to the alarm mail server 10.

FIG. 13 is a flowchart showing an example of a processing procedure in the alarm mail server 10.
The alarm mail server 10 receives observation data (such as water level and rainfall data) collected by the communication processing server 20 (step S31).

At this time, the mail delivery unit 12b refers to the value of the notification/non-notification flag 13a to determine whether its own mode is notification mode or non-notification mode (step S32). If it is non-notification mode, the routine ends and the processing procedure returns to the caller.

On the other hand, if the notification mode is selected, the mail delivery unit 12b of the alarm mail server 10 refers to the reference water level DB 23d or the reference rainfall DB 13c to compare the acquired observation data with a predetermined reference value (step S33). If the observation data does not exceed the reference value (no in step S34), the routine ends and the processing procedure returns to the caller.

If the observation data exceeds the reference value (YES in step S34), the mail delivery unit 12b creates an alarm mail and delivers the alarm mail to the destinations set in the destination list 13b (step S35).

As described above, in this embodiment, the alarm mail server 10 can be set to either a notification mode in which an alarm mail is delivered, or a non-notification mode in which no alarm mail is delivered. In the notification mode, an alarm mail is delivered when the observation data exceeds a reference value, but in the non-notification mode, no alarm mail is delivered regardless of whether the reference value is exceeded. This makes it possible to prevent erroneous delivery of mail due to abnormal values.

In the embodiment, it is possible to set a manual determination mode in which the administrator can switch between notification mode and non-notification mode at their own will, and an automatic determination mode in which the system automatically switches between notification mode and non-notification mode. In the automatic determination mode, an alarm email is sent only if, for example, a weather alert has been announced at the current time. In other words, even if observation data that would cause an alarm email to be created is detected, an alarm email will not be sent unless a weather alert has been announced. This also increases the reliability of the alarm email.

In other words, according to the embodiment, whether or not to send an alarm email is automatically determined based on predetermined conditions, making it possible to send email notifications only when truly necessary. This makes it possible to avoid erroneous notifications of information due to abnormal values during normal times, reducing the workload of administrators and improving the reliability of the system.

In actual operation, there are cases where observation data from telemeters or information released by the Japan Meteorological Agency and other organizations cannot be imported due to system failures, etc. For this reason, it is possible to make it possible for an administrator to set up an operation to send alarm email notifications. This also allows the administrator to proactively control whether or not to send notifications. Furthermore, the current status can be clearly displayed on a web page for administrators, allowing the administrator to know the status for email notifications.

As a result, it is possible to provide a river information system, a river information provision system, and a river information alarm distribution method that prevent the notification of erroneous information due to abnormal values.

<Modification>
It should be noted that the present invention is not limited to the above-described embodiment.
For example, in step S12 in Fig. 12, the criterion may be not only whether a meteorological warning has been issued (announced), but also whether a warning, alert, or special alert has been issued. Alternatively, the criterion may be the rainfall condition (how many mm or more within a predetermined time period).

Also, for example, the following guidance messages may be displayed in the windows of FIG.
For example, in the area (1. Automatic/Manual Determination Switching), guidance such as "You can switch the determination method for notifying/non-notifying emails to general residents. Select either "Automatic Determination" or "Manual Determination" and click the "Register" button. If you select "Manual Determination", please also select the notification method for email notification/non-notification switching and then click the "Register"button." may be displayed.

Also, in the area (2. Email notification/non-notification switching), guidance such as "You can manually switch the notification method for emails addressed to general residents between notification and non-notification. With "Manual determination" selected in "Automatic/manual determination switching," select "Notification mode" or "Non-notification mode," and press the "Register" button. Please note that the email notification/non-notification switching cannot be operated while automatic determination is in progress." may be displayed.
In this way, a more user-friendly operational feel can be achieved.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and their modifications are included within the scope and gist of the invention, and are included in the scope of the invention and its equivalents as set forth in the claims.
