Description

The present invention relates to a sewerage monitoring technique for supporting sewerage management.

In recent years, local heavy rains, so-called guerrilla rainstorms, have frequently occurred, and inundation damage has occurred frequently throughout the country. Especially in urban areas, as urbanization progresses, the land becomes covered with asphalt, etc. , The amount of rain that penetrates into the ground decreases, and the amount of rainwater runoff increases. As a result, the risk of urban inundation damage (inland flooding) is increasing due to an increase in the frequency of localized heavy rainfall and an increase in the amount of rainwater runoff accompanying the progress of urbanization.

In order to minimize inundation damage, local governments and related residents will work together to promote comprehensive inundation countermeasures that combine soft countermeasures and self-help efforts, in addition to steady development of efficient hardware countermeasures. Is needed.

In particular, as a software measure, it is required to provide information for voluntary evacuation related to the promotion of self-help, and the local government on the side of providing this information collects reliable information in real time and collects it in real time. There is a need for a sewerage monitoring system that can visually and quickly determine the risk of inundation.

As a sewerage monitoring system, for example, the monitoring systems of Patent Documents 1 to 3 have been proposed.

Further, in the layer display of the water level information, the display of the water level information is displayed so that it can be identified according to the situation in the pipe. Color, shape, sound, and the like can be used for the identification, but in this embodiment, the information is displayed on a drawing such as a map, so that the identification can be performed by color.

The "measured water level" described in the following description of the present embodiment means the water level measured by the water level measuring device 21 to 2N in the pipe. "% Conversion display" means a relative value of the water level measurement value by the water level measuring device in the pipe to the sewage pipe diameter.

[Example of system mode]
The sewerage monitoring system 1 of the present embodiment includes a pipe water level measurement unit 2, a pipe water level recording unit 3, a sewerage monitoring unit 4, a distribution unit 5, and an image display unit 6.

The water level measuring unit 2 in the pipe includes a water level measuring device 21 to 2N in the pipe that measures the water level information of the sewage pipeline in real time and wirelessly transmits it to the outside. The water level measuring devices 21 to 2N in the conduit are individually provided in the assembly manholes arranged in the sewage pipeline. As the water level measuring device 21 to 2N in the pipe, for example, a manhole cover having a measurement function and a wireless communication function disclosed in Patent Document 4 is applied.

The in-ditch water level recording unit 3 collects and stores the actually measured values 31 to 3N of the in-ditch water level transmitted from the in-ditch water level measuring devices 21 to 2N, respectively.

The sewerage monitoring unit 4 outputs image information that visually displays the state of the sewerage pipe in a specific area based on the map information, the sewerage pipeline information, and the sewerage pipe information.

The distribution unit 5 accepts the designation of a specific area as a display target of the status in the pipe, and distributes the image information created by the sewerage monitoring unit 4.

[Example of mode of sewerage monitoring unit 4]
The sewerage monitoring unit 4 includes computer hardware resources such as a central processing unit such as a CPU, a volatile storage unit such as a RAM, an image processing unit, and a non-volatile auxiliary storage unit such as an HDD (not shown). Then, these hardware resources cooperate with computer software resources such as OS and applications, so that the sewerage monitoring unit 4 has a rainfall information recording unit 41, a map information recording unit 42, a pipeline drawing information recording unit 43, and the like. The water level information calculation recording unit 44 and the image information creation unit 45 are implemented.

The rainfall information recording unit 41 collects and stores rainfall information from the outside. The rainfall information is information on the measured value and the predicted value of rainfall. Rainfall information can be obtained from data delivered from, for example, the Japan Meteorological Agency, the meteorological information service provided by Tokyo Metropolitan Government, and the meteorological information service provided by the Ministry of Land, Infrastructure, Transport and Tourism, which can observe local rainfall in near real time. is there.

The map information recording unit 42 stores the map information of the target area for displaying the water level / rainfall information.

The pipeline drawing information recording unit 43 stores sewerage management information (diameter, length, overburden, manhole position, manhole antenna installation location, etc. of the sewerage pipeline).

The water level information calculation recording unit 44 will be based on the actual measurement value of the water level in the pipe, the map information, and the sewerage management information provided by the water level recording unit 3, the map information recording unit 42, and the pipeline drawing information recording unit 43, respectively. The water level information including the prediction information such as the time-dependent water level change of the water level in the pipe including the above is calculated.

The prediction information can be calculated by inputting necessary parameters such as rainfall prediction and pipe water level of the rainfall information recording unit into a model formula based on a well-known sewerage water level calculation method. This calculated prediction information is water level information in which the latest measured water level data sequentially collected by the pipe pipe water level measuring device 21 to 2N is set as the "current water level" and the water level data sequentially recorded is set as the "past water level". At the same time, it is stored in the storage area of the water level information calculation recording unit 44.

The image information creation unit 45 obtains rainfall information, map information, sewage pipeline information, and pipeline information from the rainfall information recording unit 41, the map information recording unit 42, the pipeline drawing information recording unit 43, and the water level information calculation recording unit 44. Extract as layer information. Then, these layer informations are integrated to create image information that visually displays the state of the sewerage pipe in a specific area. Examples of the specific area include a specific area designated by the user and a specific area based on the position information (GPS information) of the user's image display unit 6.

The blinking display processing unit 47 creates image information for blinking and displaying the color at a blinking speed corresponding to the changing speed of the image information water level (for example, Example 1).

Upon receiving the designation of the specific point, the situation change display processing unit 48 creates image information displaying the change in the water level over time including the future time (for example, Example 2). In addition, the image information of the water level change is created based on the predicted water level, which is predicted based on the rainfall information at the specific point (the same embodiment). Further, based on the rainfall information, image information is created in which the change over time of the rainfall including the future time of the specific point is displayed on the water level change (the same embodiment).

Upon receiving the designation of the specific point, the status display processing unit 49 creates image information displaying the vertical cross section of the assembled manhole indicating the water level of the assembled manhole at the specific point (for example, Example 3). Further, when the designation of the specific point is received, image information displaying the vertical cross section of the specific point and the nearest assembly manhole on the upstream side or the downstream side of the specific point is created (the same embodiment).

In the above sewerage monitoring system 1, each information can be collected and distributed by wire or wireless, but it is preferably constructed by cloud computing, and the information is distributed on the Web to other than the distribution destination office. In addition, it will be possible to quickly obtain distribution information regardless of location on a handy terminal such as a smartphone or tablet.

Further, the water level recording unit 3 in the pipe and the sewerage monitoring unit 4 can be individually constructed on the cloud or can be constructed on a single cloud. Further, the water level recording unit 3 in the pipe and the sewerage monitoring unit 4 may be incorporated in a single device. The distribution unit 5 is not limited to being provided independently, but may be integrated with the water level recording unit 3 in the pipe and the sewerage monitoring unit 4.

[Example]
An embodiment of the sewerage monitoring system 1 will be described below, but the sewerage monitoring system of the present invention is not limited to this embodiment.

(Example 1) Displaying the status of observation points in a specific area First, the identification is performed via the homepage that operates the distribution unit 5 by accessing from the image display unit 6 of a user who wants to know the status in the sewer pipe in the specific area. When the area is designated, the distribution unit 5 transmits the designated specific area to the sewerage monitoring unit 4.

When the sewerage monitoring unit 4 receives the designation of the specific area, the image information creation unit 45 receives the specific area from the rainfall information recording unit 41, the map information recording unit 42, the pipeline drawing information recording unit 43, and the water level information calculation recording unit 44. Rainfall information, map information, sewage pipeline information, and water level information in the conduit are extracted as layer information. Then, as shown in FIG. 3, the rainfall information 11, the map information 12, the sewage pipeline information 13, and the water level information 14 are integrated, that is, superposed in the current or future sewerage pipe of the specific area. Image information 15 that visually displays the situation is created. Then, the image information 15 is output and displayed on the image display unit 6 of the user via the distribution unit 5.

An example of the image information 15 is shown in FIG. When the function of the color display processing unit 46 is selected by the user in the image information creation unit 45, the color display processing unit 46 sets the point of the assembly manhole arranged in the sewer pipe in the city map of the specific area as a "circle". The image information 15 indicated by the display symbol of "mark" is created.

The display symbols are color-coded according to the measured water level values provided in the assembly manhole. For example, "safe water level" is displayed in light blue, "caution water level" is displayed in yellow, and "warning water level" is displayed in red.

The water level in the conduit, which is the standard for the "safe water level", "caution water level", and "warning water level", is appropriately set in advance based on the diameter of the sewage pipe at the installation location of each manhole antenna.

In the display example of FIG. 4, the position of one or more assembled manholes of the sewer in a specific area specified by the user depends on the water level at the future (for example, the water level in the assembled manhole one hour after the present time). It is displayed in different colors. The current or future designation can be arbitrarily set from the user's terminal.

When the function of the blinking display processing unit 47 is selected by the user, the blinking display processing unit 47 displays the color of the display symbol at a blinking speed corresponding to the change speed of the measured water level of the water level measuring devices 21 to 2N in the pipe. Create image information that blinks.

According to the above embodiment, image information that visually displays the state of the sewer pipe in a specific area is output based on the map information, the sewer pipe information, and the pipe information. Therefore, the situation in the sewer pipe of the specific area designated by the user can be grasped in real time and intuitively.

Further, in this embodiment, the ratio of the water level to the culvert in the specific area (allowable amount of the culvert) is calculated by incorporating the sewage pipeline information in the specific area. It becomes easier to grasp. This makes it possible to promptly provide inundation information, criticism information, etc. and waterproof measures.

Furthermore, since the sewerage sewage condition in a specific area is displayed in different colors according to the water level in the sewage, the degree of the sewage condition can be intuitively grasped. In particular, in this embodiment, it is classified into three stages of "safety", "caution", and "warning", and according to this classification, it is color-coded so that it can be intuitively and intuitively grasped whether it is safe or caution. ing.

Here, if the water level information calculation recording unit 44 performs outflow analysis of the water level information of the pipes around the manholes installed at each measurement location, the peripheral portion of the measured water level measurement location can also be color-coded.

In addition, in the "Caution" and "Caution" categories, when the measured water level level is gradually increasing, the corresponding measurement point (colored) can be displayed blinking, so the risk level of the measured water level level can be displayed. Easy to grasp and pay attention to.

Further, in this embodiment, the blinking display is adopted in the classification of "Caution" and "Warning", but this display may be a function limited to "Warning" at the final stage of the rise of the pipe water level. Then, whether or not the measured water level level gradually increases may be determined, for example, by the presence or absence of a temporal increase in the moving average value of the collected measured data. Further, the blinking interval of the identification color can be easily grasped sensuously by changing it according to the rate of increase of the measured water level. In this embodiment, it is divided into three stages, but it may be further subdivided or subdivided into specific categories.

In addition, in the embodiment, by using the rainfall information, the state of the inside of the pipe at the point of the pipe in a specific area can be displayed in a blinking manner, and a plurality of information on the change in the water level due to the influence of rainfall can be displayed. Water level information can be grasped more effectively and visually.

(Example 2) Water level display in the pipe at the installation location of the water level measurement device in the pipe In addition, the situation change display processing unit 48 is selected in the image information creation unit 45, and is further displayed in the image information 15 in FIG. When an arbitrary point is selected by the user from the points of the water level measuring device 21 to 2N in the pipe, the status change display processing unit 48 is activated.

The situation change display processing unit 48 creates image information displaying the time-dependent water level change of the water level in the pipe including the future time of the selected point. More specifically, the image information of the water level change is created based on the water level predicted based on the rainfall information of the selected point. Then, this image information is output and displayed on the image display unit 6 of the user via the distribution unit 5.

An example of the image information is shown in FIG. As shown in the figure, a trend graph is created that allows you to visually grasp the past measured water level, the current measured water level, and the change in the predicted water level over time. This trend graph is popped up, for example, in the vicinity of any of the points of the water level measuring devices 21 to 2N in the pipe selected by the tap operation or the click operation by the user in the image information 15.

In the trend graph, a display bar in which the degree of the water level in the pipe is color-coded and displayed along with the change in the water level is displayed along the water level axis of the trend graph. In this display bar, the blue system becomes darker as the water level in the pipe approaches the "safe water level", while the yellow system becomes darker as it approaches the "caution water level" and the red system becomes darker as it approaches the "warning water level". Is displayed.

Further, in this embodiment, by using the rainfall information, it is possible to convert it into the point rainfall at the measurement point (measured value + predicted value), make it a yetograph, and display the water level and the rainfall in an overlapping manner. It will be possible. That is, when the situation change display processing unit 48 is activated as described above, an image in which the change with time of the rainfall amount including the future time of the specific point based on the rainfall amount information is superimposed on the water level change is displayed. Create information. Then, this image information is output and displayed on the image display unit 6 of the user via the distribution unit 5.

An example of the image information is shown in FIG. This trend graph is also popped up in the vicinity of any of the points of the water level measuring devices 21 to 2N in the pipe selected in the image information 15. By adding such a display function, it becomes possible to support the judgment of the collected information more quickly and accurately. As a result, even when the amount of rainwater outflow due to a local heavy rain called a guerrilla rainstorm suddenly increases, it is possible to promptly transmit information to minimize the inundation damage.

(Example 3) Time-dependent change in water level in the pipe at the place where the water level measurement device in the pipe is installed Further, the status display processing unit 49 is selected in the image information creation unit 45, and further displayed in the image information 15 in FIG. When an arbitrary point is selected by the user from the points of the water level measuring devices 21 to 2N in the pipe, the status display processing unit 49 is activated. Upon receiving the designation of the specific point, the status display processing unit 49 creates image information displaying the vertical cross section of the assembly manhole indicating the water level of the assembly manhole at the specific point. Then, this image information is output and displayed on the image display unit 6 of the user via the distribution unit 5.

An example of the image information is shown in FIG. As shown in the figure, a vertical cross section of the assembled manhole indicating the water level of the assembled manhole at the designated specific point is schematically displayed. Similar to the second embodiment, this vertical sectional view pops up in the image information 15 near any of the points of the water level measuring devices 21 to 2N in the pipe selected by, for example, a tap operation or a click operation by the user. Is displayed.

In the cross-sectional view of FIG. 7, the water level (for example, actually measured values 31 to 3 N) is displayed in the image of the cross-sectional view of the assembled manhole in the pipeline 30 at the designated point and time. This cross-sectional view shows the relationship between the ground height and the surrounding pipes as a cross-sectional view from the pipeline drawing information. Further, in this cross-sectional view, not only the current measured water level but also past data and future water level data (calculated predicted water level in the conduit) can be displayed by specifying the time. Furthermore, the water level at the measurement point can be displayed in% conversion. Then, by combining with the pipeline drawing information provided by the pipeline drawing information recording unit 43, the ratio of the water level to the conduit (allowable amount of the conduit) can be known, so that the prediction information of the specified specific point is provided. Is possible, and it becomes easier to grasp the situation. This makes it possible to provide inundation information, evacuation information, and prompt prediction information for waterproof measures.

Further, when a plurality of display of a specific point is selected in advance by the user, the status display processing unit 49 displays a vertical cross section of the specific point specified by the user and the nearest assembly manhole on the upstream side or the downstream side of the specific point. Create the image information that was made. Then, this image information is output and displayed on the image display unit 6 of the user via the distribution unit 5. An example of the image information is shown in FIG. As shown in the figure, a vertical cross section of the assembled manhole indicating the water level (for example, actually measured values 31 to 3 N) of the assembled manhole in the pipeline 30 at the designated specific point is schematically displayed. Similar to the cross-sectional view of FIG. 7, this vertical cross-sectional view is also in the vicinity of any of the points of the water level measuring devices 21 to 2N in the pipe selected by, for example, a tap operation or a click operation by the user in the image information 15. Pops up.

As described above, by displaying the vertical cross section of the specific point specified by the user or the assembly manhole of a plurality of specific points based on this specific point, the amount of rainwater outflow due to localized heavy rain or the like suddenly increases. In such cases, it is possible to promptly disseminate information to minimize inundation damage.
