Description

Technical Field

[0001] The present invention relates to a pond monitoring device and a pond monitoring notification system for monitoring the water level of a pond and giving notifications as needed.

Background Art

[0002] Normally, since the water in a pond does not flow into a river or the like, if the pond overflows and breaks due to heavy rain or the like, there is a risk of causing damage to surrounding houses and residents. For this reason, conventionally, cameras and water level gauges have been installed in ponds, and images from the cameras and data from the water level gauges have been transmitted to the offices of municipalities, and the offices have judged whether evacuation warnings or the like are necessary. And, as needed, information has been provided to residents via the websites of municipalities or community radio.

[0003] In addition, there is known a pond leakage detection system that does not require past observation data and can be operated immediately after the installation of equipment (see, for example, Patent Document 1). This system includes a water level information acquisition means for measuring the water level of a pond, and an arithmetic means for determining the presence or absence of leakage based on the difference between the water level measured by the water level information acquisition means and a reference water level calculated in advance. When the arithmetic means determines that there is leakage, it transmits that fact to the mobile terminals of residents around the pond.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, conventionally, residents do not always view municipal websites, and residents inside enclosed homes or cars may have difficulty hearing the voices from loudspeakers broadcasting via public address systems, potentially preventing evacuation warnings from being reliably disseminated. Furthermore, the system described in Patent Document 1 only transmits information to residents' mobile devices, meaning that if residents do not check their mobile devices or do not own them, the information may not be disseminated.

[0006] Therefore, the present invention aims to provide a reservoir monitoring device and a reservoir monitoring notification system that can reliably disseminate information such as evacuation warnings to residents. [Means for solving the problem]

[0007] To solve the above problems, the invention described in claim 1 is a reservoir monitoring device characterized by comprising: a water level monitoring means for monitoring the water level of a reservoir; an alarm determination means for determining whether an alarm, including an evacuation warning, is necessary based on the monitoring results from the water level monitoring means; and an FM broadcasting means for broadcasting an audio message to an FM radio in accordance with the alarm determined by the alarm determination means.

[0008] The invention described in claim 2 is a reservoir monitoring notification system characterized in that a reservoir monitoring device described in claim 1, provided for each reservoir, and a reservoir monitoring server are communicated together, the reservoir monitoring server includes a map information storage means for storing map information including location information of the plurality of reservoirs, the reservoir monitoring device transmits an alarm determined by the alarm determination means to the reservoir monitoring server, the reservoir monitoring server determines the direction in which residents around the reservoir should evacuate based on the received alarm and the map information, transmits the determined direction to the reservoir monitoring device, and the reservoir monitoring device broadcasts an audio message corresponding to the received direction via FM radio from the FM broadcasting means. [Effects of the Invention]

[0009] According to the invention described in claim 1, based on the monitoring results of the reservoir water level, voice messages corresponding to alarms such as evacuation warnings are broadcast on FM radio, making it possible to reliably disseminate information such as evacuation warnings to residents. In other words, residents in the surrounding area can properly hear information such as evacuation warnings, whether they are at home or in their car, as long as they have their radio receivers turned on and activated. Moreover, since radio receivers are usually installed in every home and every car, it is possible to reliably disseminate information such as evacuation warnings to residents without requiring any new equipment.

[0010] According to the invention described in claim 2, the direction in which residents around a reservoir should evacuate is determined, and an audio message corresponding to that direction is broadcast via FM radio from the reservoir monitoring device at each reservoir, thereby ensuring that residents are reliably informed of the direction they should evacuate. Moreover, since the direction in which residents around a reservoir should evacuate is determined based on the water level monitoring results (alarms) at multiple reservoirs and map information, it is possible to evacuate residents in a safe direction according to the water level situation at each reservoir. [Brief explanation of the drawing]

[Figure 2] Figure 1 is a flowchart showing the operation flow of the alarm task of the reservoir monitoring device. [Figure 3] Figure 1 is a schematic block diagram showing the configuration of the reservoir monitoring server in the reservoir monitoring and notification system. [Figure 4] Figure 3 is a flowchart showing the operation flow of the monitoring task on the reservoir monitoring server. [Modes for carrying out the invention]

[0012] The present invention will be described below based on the illustrated embodiments.

[0013] Figure 1 is a schematic diagram showing a reservoir monitoring device 1 and reservoir monitoring notification system 10 according to an embodiment of the present invention. The reservoir monitoring device 1 and reservoir monitoring notification system 10 are a device and system for monitoring the water level of reservoirs T and notifying as necessary, and the reservoir monitoring device 1 installed for each reservoir T and the reservoir monitoring server 6 are communicated together. Here, the reservoir monitoring server 6 may be installed anywhere, but for example, it is set up in the municipal office that monitors and manages multiple reservoirs T.

[0014] The reservoir monitoring device 1 mainly comprises a camera (water level monitoring means) 2, a water level gauge (water level monitoring means) 3, an FM broadcaster (FM broadcasting means) 4, and a control device (alarm determination means) 5. The camera 2, FM broadcaster 4, and control device 5 are mounted on a support column P installed near the reservoir T, and the water level gauge 3 is mounted in the reservoir T. The control device 5 is also connected to the camera 2, water level gauge 3, and FM broadcaster 4 in a data transmission manner.

[0015] Camera 2 continuously photographs the reservoir T and monitors its water level, transmitting the captured images to the control device 5 in real time. Similarly, the water level gauge 3 continuously measures the water level of the reservoir T and monitors its water level, transmitting the measured water level to the control device 5 in real time. In addition, the control device 5 periodically transmits images from camera 2 and water levels from water level gauge 3 to the reservoir monitoring server 6, regardless of whether or not an alarm is triggered (as described later).

[0016] The FM radio transmitter 4 is a transmitter that broadcasts voice messages on FM radio in response to alarms and other events determined by the control device 5, as will be described later. Specifically, it is equipped with a sound source that stores multiple voice messages, and when the type of alarm is transmitted from the control device 5, it selects a voice message from the sound source corresponding to the alarm and broadcasts it on FM radio. For example, if an evacuation warning alarm is transmitted from the control device 5, it will broadcast a voice message such as, "An alarm has been triggered at the ○○ reservoir, please evacuate." on FM radio.

[0017] Then, when a radio receiver R provided in a house H or the like around the pond T receives this FM radio broadcast, the resident M can listen to the voice message. Here, in this embodiment, when the FM broadcaster 4 broadcasts a voice message by FM radio, the radio receiver R is configured to automatically start up. That is, prior to the broadcast of the voice message, a start signal is transmitted from the FM broadcaster 4, and the radio receiver R automatically starts up by receiving this signal. Note that the broadcast range of the FM broadcaster 4 is set to an area affected by the corresponding pond T.

[0018] The control device 5 is a device that controls the FM broadcaster 4 and the like, and includes an alarm task and a communication interface for communicating with the pond monitoring server 6 or the like. The alarm task is always active and causes the FM broadcaster 4 to broadcast a voice message by FM radio based on the monitoring result of the pond T.

[0019] First, as shown in FIG. 2, based on an image from the camera 2, the water level from the water level gauge 3, etc., it is determined whether an alarm including an evacuation warning is necessary (step S1). That is, based on an image indicating the water level situation or the rising water situation of the pond T or the measured water level of the pond T, it is determined whether it is necessary to output and issue an alarm such as an evacuation warning, and if so, what kind of alarm is required. Such a determination criterion may be any as long as the safety of the resident M can be ensured, for example, it may be equivalent to the criterion conventionally judged by the local government office. Also, when making the determination, meteorological information (weather, rainfall, etc.) may be considered for the determination.

[0020] As a result, when it is determined that an alarm is necessary (in the case of "Y" in step S2), the pond monitoring device, that is, the identification information of the pond T, and the alarm information including the type and content of the determined alarm are notified to the pond monitoring server 6 (step S3).

[0021] Subsequently, a voice message corresponding to the determined alarm is broadcast on the FM radio (step S4). That is, when the type of the determined alarm is transmitted to the FM broadcaster 4, as described above, the voice message corresponding to the alarm is broadcast on the FM radio from the FM broadcaster 4. Thus, in this embodiment, the FM broadcaster 4 is provided with a sound source storing the voice message, but the control device 5 may be provided with the sound source, and the voice message from the sound source may be transmitted to the FM broadcaster 4 for FM radio broadcast.

[0022] And until the instruction information described later is received from the pond monitoring server 6 (when "N" in step S5), the voice message corresponding to the alarm is repeatedly broadcast on the FM radio a predetermined number of times or for a predetermined period (step S6). Here, the predetermined number of times or the predetermined period is set to the number of times or the period by which the voice message can be made known to the resident M.

[0023] On the other hand, when the instruction information described later is received from the pond monitoring server 6 (when "Y" in step S5), the voice message corresponding to the instruction information is broadcast on the FM radio (step S7). That is, similar to the voice message corresponding to the above alarm, the sound source of the FM broadcaster 4 stores a voice message corresponding to the type of the instruction information. Then, when the instruction information is transmitted to the FM broadcaster 4, the voice message corresponding to the instruction information is broadcast on the FM radio from the FM broadcaster 4. For example, when receiving instruction information such as "should evacuate in the ×× direction" from the pond monitoring server 6, a voice message such as "Residents around the ○○ pond, please evacuate in the ×× direction." is broadcast on the FM radio.

[0024] And such a voice message is repeatedly broadcast on the FM radio a predetermined number of times or for a predetermined period (step S8). Here, the predetermined number of times or the predetermined period is set to the number of times or the period by which the voice message can be made known to the resident M, similar to the case of the above alarm.

[0025] The reservoir monitoring server 6 is a server that guides local residents M to safety during evacuation, and as shown in Figure 3, it mainly comprises a map database (map information storage means) 61, a communication unit 62, a monitoring task 63, and a central processing unit 64 that controls these.

[0026] Map database 61 is a database that stores map information including the location information of multiple reservoirs T. In other words, it is an electronic map that stores not only topography, roads, and buildings / houses H, but also the location information (latitude, longitude) of each reservoir T and the location information of each evacuation site.

[0027] The communication unit 62 is an interface for communicating with external devices such as the reservoir monitoring device 1. Specifically, it receives alarm information from the reservoir monitoring device 1 and transmits instruction information to the reservoir monitoring device 1.

[0028] Monitoring task 63 is a task program that determines the direction in which residents M should evacuate based on the status of each reservoir T, and is activated when alarm information is received from reservoir monitoring device 1. In this case, alarm information may be received from only one reservoir monitoring device 1, or from multiple reservoir monitoring devices 1.

[0029] First, as shown in Figure 4, the area where the evacuation direction should be broadcast is selected (step S11). That is, based on the location of the reservoir monitoring device 1 that transmitted the alarm information, i.e., the location of the reservoir T where the alarm occurred, the type and content of the alarm, the geographical relationship between this reservoir T and surrounding reservoirs T, the location of houses H, etc., the area where evacuation should be guided, i.e., the reservoir monitoring device 1 to which the broadcast should be made, is determined.

[0030] Next, various data such as the location of the reservoir T where the alarm occurred, the type and content of the alarm, images and water levels of this reservoir T and surrounding reservoirs T, and weather information (weather, rainfall, etc.) are analyzed (Step S12). In other words, the current and future water level conditions of each reservoir T are analyzed based on the various data.

[0031] Next, based on the analysis results, the direction in which residents M should evacuate (a relatively safe direction and route where the reservoir T will not collapse) is determined (step S13). That is, based on the current and future water level conditions of each reservoir T, and map information from the map database 61, the direction and location of evacuation for residents M around the reservoir monitoring device 1, i.e., the reservoir T, determined in step S11 is determined. Therefore, the direction of evacuation may differ depending on the reservoir monitoring device 1 (reservoir T). For example, it may be determined that residents M around one reservoir T should evacuate in direction A, while residents M around another reservoir T should evacuate in direction B.

[0032] Then, instruction information (broadcast instruction) including the determined direction is transmitted to the reservoir monitoring device 1 determined in step S11 (step S14). Here, the instruction information may include instructions such as "You should evacuate in the direction of XX" or "You should evacuate to the XX evacuation site." In response, as described above, an audio message such as "Residents around the XX reservoir should evacuate in the direction of XX" is broadcast on FM radio from the FM broadcaster 4.

[0033] Next, we will explain the operation of the reservoir monitoring device 1 and reservoir monitoring notification system 10 with this configuration.

[0034] First, at each reservoir T, the reservoir monitoring device 1 periodically transmits images of the reservoir T and the measured water level to the reservoir monitoring server 6, and the alarm task of the control device 5 is constantly activated. When it is determined that an alarm, including an evacuation warning, needs to be output, the alarm information is notified to the reservoir monitoring server 6, and an audio message corresponding to the determined alarm is broadcast on FM radio from the FM broadcaster 4.

[0035] Meanwhile, upon receiving the alarm information, the reservoir monitoring server 6 activates monitoring task 63, and as described above, determines the direction in which residents M around reservoir T should evacuate. Instructional information including this direction is then transmitted to the reservoir monitoring device 1. Upon receiving this, the FM broadcaster 4 of the reservoir monitoring device 1 broadcasts an audio message corresponding to the received direction via FM radio.

[0036] Thus, with this reservoir monitoring device 1 and reservoir monitoring and notification system 10, voice messages corresponding to alarms such as evacuation warnings are broadcast on FM radio based on the water level monitoring results of reservoir T, making it possible to reliably inform residents M of evacuation warnings and other information. In other words, residents M in the surrounding area can appropriately hear evacuation warnings and other information whether they are at home or in their car, as long as they have their radio receiver R turned on and activated.

[0037] Moreover, since radio receivers R are typically installed in every home and every car, it is possible to reliably disseminate information such as evacuation warnings to residents M without requiring any new equipment. Furthermore, in this embodiment, the radio receiver R is set to activate automatically, so residents M can reliably receive information such as evacuation warnings even without turning on the radio receiver R.

[0038] Furthermore, the direction in which residents M should evacuate around reservoir T is determined, and an audio message corresponding to that direction is broadcast via FM radio from the reservoir monitoring device 1 at each reservoir T, thus ensuring that residents M are reliably informed of the direction they should evacuate. Moreover, since the direction in which residents M should evacuate around reservoir T is determined based on water level monitoring results (alarms) from multiple reservoirs T, weather information, map information, etc., it is possible to evacuate residents M in a safe direction according to the water level situation and water level forecast for each reservoir T.

[0039] Although embodiments of this invention have been described above, the specific configuration is not limited to the embodiments described above, and any design changes, etc., that do not depart from the gist of this invention are also included. For example, in the above embodiment, the camera 2, FM broadcaster 4, and control device 5 are arranged on the same single support column P, but they may be arranged in different locations.
