Remote monitoring system, remote monitoring method, image generation device and image generation method

Technical Field

Embodiments of the present invention relate to a remote monitoring system, a remote monitoring method, a remote monitoring program, an image generation device, an image generation method, and an image generation program.

Background

As a technique for displaying time-series data of the water amount of a water source such as a river network around a drainage pumping station, there is known a technique for displaying a river network in a pattern and arranging a place name and a window on a water level measurement point side of the river network (for example, see patent document 1). In this technique, time-series data of the water amount is displayed by displaying the current measured water level in a window. This makes it possible to spatially display the water level distribution at the current time on the map of the river network. In this technique, the water level at each water level measurement point after a predetermined time is predicted, and the time-series data of the predicted water level is displayed.

Further, there is known a technique of predicting a breakdown or a water shortage of a reservoir in a short time by using current water level data and rainfall data of the reservoir (for example, see patent document 2). In this technique, whether or not a burst or water shortage occurs is determined by comparing the result of predicting the change in the water level with height data stored in advance as a criterion of a burst and water shortage of the reservoir.

Disclosure of Invention

Problems to be solved by the invention

In the above-described technique, an operator views water volume measurement data of a water source such as a river network, and the water volume measurement data is displayed by performing time-series processing on a map by the operation of the operator. In addition, a simulated prediction of the water source level is made to aid the operator's operation.

The river system is relatively simple, and even in the case where a river management facility has many places as one pump station, it is not difficult to grasp the state of the entire area of the water system by this method.

In recent years, a drain and a water guide for communicating water between rivers have been newly provided, and a river network has become more complicated and wider. Specifically, when the river network is complicated, the number of windows for displaying data needs to be increased accordingly. Therefore, a large amount of numerical data is arranged on the screen, and a screen which is very difficult to determine is constituted. Further, although the spatial display of the water level data is possible, only the water level distribution at the current time or at a specific time is displayed, and the time-series display is not possible. Further, if the number of trends (trend) of the predicted water level increases, a display which is very difficult to judge is configured, and even if the temporal display of the water level data is enabled, the spatial display is not possible.

The foregoing is not limited to the river system, and is also applicable to the case where time series data of the water amount of the source water such as a well is displayed.

Additionally, consider the prediction of a breach or water shortage for multiple reservoirs. In the aforementioned technique, it is necessary to prepare in advance height data that becomes a standard for the burst and water shortage of a plurality of reservoirs, respectively.

Here, the use of water level data of a water source such as a well to predict foundation settlement near the water source is considered. In this case, as in the case where a break or water shortage is predicted for a plurality of reservoirs, it is necessary to prepare water level data as a standard for foundation settlement near the water source. Further, the conventional monitoring system has a problem that the ground settlement cannot be predicted because the water level is not measured.

The present invention has been made in view of the above circumstances, and a first object thereof is to provide a remote monitoring system, a remote monitoring method, a remote monitoring program, an image generating apparatus, an image generating method, and an image generating program, which are capable of easily grasping the water level and/or water quality of a water source even when the water source is wide.

Detailed Description

(first embodiment)

The remote monitoring system, the remote monitoring method, the remote monitoring program, the image generating apparatus, the image generating method, and the image generating program according to the embodiments will be described below with reference to the drawings.

Fig. 1 is a diagram showing an example of a configuration of a remote monitoring system according to an embodiment. The remote monitoring system 1 shown in fig. 1 illustrates a system for remote monitoring of an underground water membrane filtration system. The remote monitoring system 1 includes: an underground water membrane filtration system 100a, an underground water membrane filtration system 100b, a remote monitoring server 200, and a terminal device 300. The underground water membrane filtration system 100a, the underground water membrane filtration system 100b, the remote monitoring server 200, and the terminal device 300 are connected via a communication network such as the internet or a mobile phone network.

The underground water membrane filtration system 100a and the underground water membrane filtration system 100b are distributed water channel systems that can be installed in a water source such as a well and change underground water into safe and safe drinking water by membrane filtration treatment. The groundwater membrane filtration system 100a and the groundwater membrane filtration system 100b measure the water level and/or the water quality of the water source periodically or aperiodically. The groundwater membrane filtration system 100a and the groundwater membrane filtration system 100b periodically or aperiodically transmit measurement information including either or both of water level information (hereinafter, referred to as "water level information") of a measured water source and water quality information (hereinafter, referred to as "water quality information") of membrane-filtered treated water to the remote monitoring server 200.

When the remote monitoring server 200 receives the measurement information transmitted from the underground water membrane filtration system 100a and the underground water membrane filtration system 100b, either one or both of the water level information and the water quality information included in the measurement information are stored.

In addition, the remote monitoring server 200 generates (displays) an image indicating either or both of the stored water level information and water quality information. Hereinafter, an image showing (displaying) water level information is referred to as a "water level information display image", and an image showing (displaying) water quality information is referred to as a "water quality information display image". Specifically, the remote monitoring server 200 divides the region into substantially equal-sized grids based on the latitude and longitude, and forms (displays) a square or quadrangular area (hereinafter also referred to as "grid") on the map. Further, the remote monitoring server 200 indicates (displays) water level information or water quality information on a grid corresponding to the respective positions of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b, among grids formed (displayed) in a region including the positions where either or both of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b are installed. For example, the remote monitoring server 200 displays water level information in different colors according to the water level. In addition, the remote monitoring server 200 displays water quality information in different colors according to water quality.

In the present embodiment, the area (grid) is not limited to the aforementioned size (substantially the same size) and shape (square or quadrangle). The size and shape of the mesh may be different and may be set arbitrarily. For example, the mesh may be formed by terrain segmentation, or the mesh may be formed by water vein shape segmentation.

In addition, the boundary (line forming the grid) of the divided regions may be a straight line or a curved line. In the case of using a straight line, the straight line may be only a vertical line, only a horizontal line, or only a diagonal line, or a plurality of kinds may be combined therefrom.

When receiving the display request information transmitted from the terminal device 300 and the display request information includes information requesting a water level information display image, the remote monitoring server 200 generates a water level information display image and transmits the generated water level information display image to the terminal device 300. Further, when receiving the display request information transmitted from the terminal device 300 and the display request information includes information requesting the water quality information display image, the remote monitoring server 200 generates the water quality information display image and transmits the generated water quality information display image to the terminal device 300.

The terminal device 300 transmits display request information to the remote monitoring server 200 by the operation of the user. The display request information includes information requesting display of either one or both of the water level information display image and the water quality information display image. When the terminal device 300 receives either one or both of the water level information display image and the water quality information display image transmitted from the remote monitoring server 200 for the display request information, the received water level information display image or water quality information display image is displayed.

Hereinafter, the underground water membrane filtration system 100a and the underground water membrane filtration system 100b will be referred to as the underground water membrane filtration system 100 without distinction. The same applies to each configuration of the underground water membrane filtration system 100.

(underground water membrane filtration system)

Fig. 2 is a schematic configuration diagram of the underground water membrane filtration system according to the embodiment. The underground water membrane filtration system 100 includes: a groundwater draw system 102, a raw water tank 104, a pre-filter 106, a membrane filter 108, a treated water tank 110, a monitoring device 112, a water quality meter 114a, and a water collection tank 116.

The groundwater drawn by the groundwater draw system 102 is stored in a raw water tank 104. The pre-filter 106 filters the groundwater drawn by the groundwater drawing system 102 to the extent of normal potable water as a pre-treatment such as sand filtration. The membrane filter 108 further treats the water pretreated with the pre-filter 106 with various filters to produce safer drinking water. Specifically, the membrane filter 108 removes bacteria or protozoa such as O-157 or Cryptosporidium, which are causative agents of food poisoning, from the water pretreated by the pre-filter 106. The treatment water tank 110 stores water from which bacteria and protozoa have been removed by the membrane filter 108.

The monitoring device 112 continuously measures and records the concentration of residual chlorine in the water stored in the treated water tank 110. When the measurement result of the residual chlorine concentration by the monitoring device 112 indicates an abnormality, the underground water membrane filtration system 100 is automatically stopped. The water quality meter 114a measures the water quality of the treated water stored in the treated water tank 110 through membrane filtration. Specifically, the water quality meter 114a measures a water quality standard item included in the water quality standard of the water course.

The water quality standard items comprise: general bacteria, total trihalomethanes, escherichia coli, trichloroacetic acid, cadmium and compounds thereof, bromodichloromethane, mercury and compounds thereof, bromoform, selenium and compounds thereof, formaldehyde, lead and compounds thereof, zinc and compounds thereof, arsenic and compounds thereof. In addition, the water quality standard items include: aluminum and its compounds, hexavalent chromium compounds, iron and its compounds, nitrite nitrogen, copper and its compounds, cyanide ions and cyanogen chloride, sodium and its compounds, nitrate nitrogen and nitrite nitrogen, manganese and its compounds, fluorine and its compounds, chloride ions. In addition, the water quality standard items include: boron and its compounds, calcium, magnesium, etc. (hardness), carbon tetrachloride, evaporation residues, 1, 4-dioxane, anionic surfactants, cis-1, 2-and trans-1, 2-dichloroethylene, oxytetracycline, dichloromethane, 2-methylisobornene, tetrachloroethylene. In addition, the water quality standard items include: nonionic surfactant, trichloroethylene, phenols, benzene, organics (amount of Total Organic Carbon (TOC)), chloric acid, pH, chloroacetic acid, taste, chloroform, odor, dichloroacetic acid, color, dibromochloromethane, turbidity, bromic acid.

The water quality meter 114a outputs water quality information including a result of measuring the water quality of the membrane-filtered water to the monitoring device 112. When the monitoring apparatus 112 acquires the water quality information from the water quality meter 114a, the water quality information and the measurement result of the concentration of the residual chlorine in the water are transmitted to the remote monitoring server 200. The sump 116 stores water stored in the processing tank 110 and public water supply.

(underground water drawing system)

Fig. 3 is a schematic diagram showing an example of the groundwater pumping system according to the first embodiment. The groundwater drawing system 102 includes: a well 11, a pump 12 for pumping the groundwater W flushed out of the well 11, a water pumping pipe 13, and a water level gauge 19.

The well 11 has a gas impermeable protective pipe 16, and the protective pipe 16 is inserted into an excavation hole H excavated from the ground G downward to the aquifer X. The protection pipe 16 is a bottomed cylindrical pipe for protecting the excavated hole H from earth and sand falling or the like. A water intake port 16a for sucking groundwater in the aquifer X into the protection pipe 16 is formed near the bottom of the protection pipe 16 at a position of the aquifer X when inserted into the excavation hole H. A metal mesh 17 for preventing sand or the like from entering the protective pipe 16 is attached to the intake port 16 a. The term "gas impermeability" means that gas does not permeate through the soil such as the aquifer X from the protective tube 16.

The pump 12 and the water pumping piping 13 may be well-known pumps and water pumping piping for wells.

The water level gauge 19 measures the level of groundwater W flushed in the well. An example of the water level gauge 19 is a bubble type water level gauge. The bubble type water level gauge calculates the water level by measuring the pressure required to send bubbles to the water bottom by a bubble tube having an open end disposed on the water bottom. The water level gauge 19 transmits water level information including the water level measurement result of the groundwater W to the monitoring device 112.

(monitoring device)

Fig. 4 shows an example of the monitoring device according to the first embodiment. The monitoring device 112 includes: a communication unit 150, a control unit 160, a storage unit 170, and a bus 180 such as an address bus and a data bus for electrically connecting the above-described components as shown in fig. 4.

The communication section 150 is realized by a communication module. The communication unit 150 communicates with the remote monitoring server 200 via the communication network 50.

The control Unit 160 is configured by an arithmetic Processing device such as a CPU (Central Processing Unit), and functions as the acquisition Unit 162, the determination Unit 164, the generation Unit 166, and the Processing control Unit 168 by executing a program 172 stored in the storage Unit 170.

The acquisition unit 162 acquires the measurement result of the concentration of residual chlorine in the water stored in the treated water tank 110. When the acquisition unit 162 acquires the measurement result of the concentration of the residual chlorine in the water stored in the treated water tank 110, the measurement result of the concentration of the residual chlorine in the water stored in the treated water tank 110 is output to the determination unit 164.

The acquisition unit 162 acquires water level information from the water level gauge 19 and water quality information from the water quality gauge 114 a. When the acquisition unit 162 acquires water level information from the water level gauge 19, the water level information is output to the generation unit 166. When the acquisition unit 162 acquires the water quality information from the water quality meter 114a, the water quality information is output to the generation unit 166.

When the determination unit 164 obtains the measurement result of the residual chlorine concentration in the water stored in the treated water tank 110 output from the acquisition unit 162, the residual chlorine concentration in the water is compared with the residual chlorine concentration threshold. The determination unit 164 outputs a determination result including a comparison result between the residual chlorine concentration in the water and the residual chlorine concentration threshold value to the process control unit 168.

When the generation unit 166 acquires either or both of the water level information and the water quality information output by the acquisition unit 162, measurement information is generated, which includes either or both of the water level information and the water quality information, and identification information of the water source from which either or both of the water level information and the water quality information are obtained. Examples of the identification information of the water source include identification information of the groundwater membrane filtration system 100 such as ID, water source type, latitude, longitude, management company, construction company, year of use, well depth, and well diameter. When the generation unit 166 generates the measurement information, the measurement information is transmitted to the remote monitoring server 200 through the communication unit 150.

The processing control unit 168 acquires the determination result output by the determination unit 164. When the determination result includes information indicating that the residual chlorine concentration in the water is equal to or higher than the residual chlorine concentration threshold, the treatment control unit 168 continues the treatment of the underground water membrane filtration system 100. On the other hand, when the determination result includes information indicating that the residual chlorine concentration in the water is lower than the residual chlorine concentration threshold value, the processing control unit 168 may perform a predetermined error process. Specifically, when the determination result includes information indicating that the residual chlorine concentration in the water is lower than the residual chlorine concentration threshold value, the process control unit 168 stops the process of the groundwater membrane filtration system 100 and sounds an alarm.

The storage unit 170 is implemented by a storage device such as a nonvolatile memory. The storage unit 170 stores a program 172.

(remote monitoring server)

Fig. 5 shows an example of a remote monitoring server according to the first embodiment. The remote monitoring server 200 includes: a communication unit 250, a control unit 260, a storage unit 270, and a bus 290 such as an address bus and a data bus for electrically connecting the above-described components as shown in fig. 5.

The communication section 250 is realized by a communication module. The communication unit 250 communicates with the monitoring apparatus 112 and the terminal apparatus 300 via the communication network 50. The communication unit 250 receives the measurement information transmitted from the monitoring apparatus 112. When the communication unit 250 receives the measurement information, the measurement information is output to the control unit 260.

Further, the communication unit 250 receives the display request information transmitted from the terminal device 300. When the communication unit 250 receives the display request information, the display request information is output to the control unit 260.

In the map for display, the region to be divided may be arbitrarily set according to the purpose. The area is a minimum unit of division obtained by dividing the region into a plurality of regions.

Thus, the user who has performed an operation to request display of the water level information display image can capture all of the water levels observed at a plurality of places. In the example shown in fig. 8, colors are represented by different shades instead of colors according to water levels.

After the application 376 is started, when the user performs an operation to the operation unit 385 to request display of either one or both of the water level information display image and the water quality information display image, the control unit 360 generates display request information containing information requesting display of either one or both of the water level information display image and the water quality information display image. The control unit 360 outputs the display request information to the communication unit 350.

In step S1014, when the communication unit 350 of the terminal device 300 acquires the display request information output by the control unit 360, the display request information is transmitted to the remote monitoring server 200.

The setting of the region set in the map can be arbitrarily set. When the remote monitoring server 200 generates the display image information, the generated display image information is transmitted to the terminal device 300.

When the terminal device 300 receives the display image information transmitted from the remote monitoring server 200, it displays it by processing either or both of the water level information display image and the water quality information display image contained in the display image information.

With such a configuration, it is possible to acquire information in near real time as compared with the case of using information measured in a general observation well. By being able to acquire information in near real time, variations in measurement information can be captured with high accuracy. The display image information may be updated at a prescribed cycle. When drawing a water source, particularly underground water and lake water, it is desirable to shorten the monitoring interval as much as possible because the water level drops in minutes. Specifically, the update is preferably performed in a period of less than five minutes each time, and more preferably at least once every 2 minutes. In addition, the water level and/or quality of groundwater in a plurality of locations can be automatically and remotely monitored in a unified manner. In addition, by arranging the grid images in time series, the water level change and the water quality change of the well can be comprehensively and dynamically grasped.

By being capable of observing the water quality change in real time, the salt hydration expansion of the underground water basin can be comprehensively captured. In addition, it is possible to effectively grasp the change in the quality of the groundwater used as a drinking water source and to predict the risk of a water quality accident associated with the change in the quality of the groundwater in an early stage. Specifically, by measuring water quality data for each aquifer, it is possible to comprehensively grasp and predict at which depth groundwater water quality fluctuation occurs.

By comparing the water levels and/or water qualities displayed on adjacent grids, it is possible to estimate the change occurring in the underground water vein and the surrounding points of the points, not limited to the points corresponding to the grids. The more the number of pieces of measurement information increases, the more the estimation accuracy can be improved.

For example, the remote monitoring server 200 displays water level information in different colors according to the water level.

When receiving the display request information transmitted from the terminal device 300 and the display request information includes information requesting a water level information display image, the remote monitoring server 200 generates a water level information display image and transmits the generated water level information display image to the terminal device 300.

For example, the remote monitoring server 200 displays water level information in different colors according to the water level.

According to the remote monitoring system 1 of the modification, the remote monitoring server 200 acquires the water level information (still water level or kinetic water level) stored in the measurement information table 274 from the display request information transmitted from the terminal device 300, and displays the water level information on the mesh corresponding to the position of either or both of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b, thereby generating display image information.

Specifically, the remote monitoring server 200 generates a water level information display image by displaying either or both of the still water level and the kinetic water level contained in the water level information on a grid corresponding to the position of either or both of the underground water membrane filtration system 100a and the underground water membrane filtration system 100 b. With such a configuration, it is possible to acquire information in near real time as compared with the case of using information measured in a general observation well. By being able to acquire near real-time information, it is possible to capture changes in either or both of the still water level and the moving water level with high accuracy. Moreover, the water level change of the well can be observed in real time, and the long-term activities of the static water level and the dynamic water level can be comprehensively captured by combining the water level of the well and the measurement of the starting and stopping signals of the water suction pump.

When the display image generator 464 generates either one or both of the water level information display image and the water quality information display image, the display screen information including either one or both of the water level information display image and the water quality information display image is output to the communication unit 450.

(remote monitoring System operation)

An example of the operation of the remote monitoring system according to the modification can be applied to the operation of the remote monitoring system according to the foregoing embodiment. However, in step S1016, the communication unit 450 of the remote monitoring server 400 receives the display request information transmitted from the terminal device 300.

When the display image generation unit 464 acquires the display request information from the communication unit 450, and when the display request information includes information requesting the display of the water level information image, the display image generation unit 464 acquires the water level information stored in the measurement information table 474 of the storage unit 470 and outputs the acquired water level information to the calculation unit 466. When the calculation unit 466 acquires the water level information output from the display image generation unit 464, the difference between the water level measurement result included in the water level information and the initial water level is calculated. The operation part 466 outputs the difference between the water level measurement result and the initial water level to the display image generation part 464.

When the display image generating unit 464 acquires the difference between the water level measurement result output from the arithmetic unit 466 and the initial water level, a water level information display image is generated which displays the difference between the water level measurement result and the initial water level on the grids corresponding to the respective positions of the underground water film filtration system 100a and the underground water film filtration system 100b among the grids formed in the region including the position where either or both of the underground water film filtration system 100a and the underground water film filtration system 100b are set.

When the display image generation unit 464 acquires the display request information from the communication unit 450, and when the display request information includes information requesting the display of the water quality information display image, the display image generation unit 464 acquires the water quality information stored in the measurement information table 474 of the storage unit 470 and outputs the acquired water quality information to the calculation unit 466. When the calculation unit 466 acquires the water quality information output from the display image generation unit 464, the difference between the water quality measurement result included in the water quality information and the initial water quality is calculated. The calculation unit 466 outputs the difference between the water quality measurement result and the initial water quality to the display image generation unit 464.

When the display image generating unit 464 acquires the difference between the water quality measurement result output from the computing unit 466 and the initial water quality, a water quality information display image is generated which displays the difference between the water quality measurement result and the initial water quality on a grid corresponding to each position of the underground water film filtration system 100a and the underground water film filtration system 100b among grids formed in a region including the position where either or both of the underground water film filtration system 100a and the underground water film filtration system 100b are set.

In the above-described modification, the case where the calculation unit 466 calculates the difference between the water level measurement result and the initial water level and the difference between the water quality measurement result and the initial water quality has been described, but the present invention is not limited thereto. For example, the calculation unit 466 may calculate either or both of the rate at which the water level measurement result fluctuates and the rate at which the water quality measurement result fluctuates. The calculation unit 466 may predict the future water level and water quality based on the rate of change in the water level measurement result and the rate of change in the water quality measurement result.

Specifically, when the dynamic water level decreases by 3 meters within the last 3 days, it can be predicted that the conductivity of the water in the source may increase by 20%. For example, the calculation unit 466 may calculate either or both of the secular change of the water level measurement result and the secular change of the water quality measurement result by the calculation formula (1).

Change over time (measured value of water quality at predetermined date and time 1-measured value of water quality at predetermined date and time 2)/predetermined period (1)

The date and time 1 may be set to, for example, the time of drawing. The predetermined date and time 2 may be set to, for example, the current time (when the chronological change is derived).

According to the remote monitoring system according to the modification, the remote monitoring server 400 acquires either one or both of the water level information and the water quality information stored in the measurement information table 474 based on the display request information transmitted from the terminal device 300, and calculates either one or both of the difference between the water level measurement result included in the water level information and the initial water level and the water quality measurement result included in the water quality information and the initial water quality. Also, the remote monitoring server 400 generates display image information by displaying any one or both of a difference between the water level measurement result amount and the initial water amount and a difference between the water quality and the initial water quality on a grid corresponding to the position of any one or both of the underground water film filtration system 100a and the underground water film filtration system 100 b.

With such a configuration, it is possible to acquire information in near real time as compared with the case of using information measured in a general observation well. By being able to acquire information in near real time, variations in measurement information can be captured with high accuracy.

Further, since any one or both of the change in the water level measurement result from the initial water level and the change in the water quality measurement result from the initial water quality can be displayed by being able to display the difference between the water level measurement result and the initial water level and the water quality measurement result and the initial water quality, any one or both of the change in the water level measurement result and the change in the water quality measurement result can be captured with higher accuracy.

In the above-described embodiment and modification, the well has been described as an example of the water source, but the present invention is not limited to this example. For example, the present invention can be applied to a river. In this case, the system is suitable for the underground water membrane filtration system 100a and the underground water membrane filtration system 100b, and is a distributed water channel system which is installed in a water source such as a river and changes river water into safe drinking water by membrane filtration treatment.

In the above-described embodiment and modification, the case where the remote monitoring server 200 displays the water level information or the water quality information on the grids corresponding to the respective positions of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b among the grids formed in the region including the position where either or both of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b are installed in the map has been described, but the present invention is not limited to this example.

For example, the remote monitoring server 200 may display water level information and water quality information on a grid formed in a region including a position where either or both of the underground water membrane filtration system 100a and the underground water membrane filtration system 100b are installed, or on a grid corresponding to the respective positions of the underground water membrane filtration system 100a and the underground water membrane filtration system 100 b.

Specifically, by dividing the region set in the map into a plurality of regions and displaying the regions (grids) divided into grids, the water level information or the water quality information may be indicated (displayed) on each grid displayed, or the water level information or the water quality information may be indicated (displayed) in the frame or the inside of each grid displayed. In addition, two or more items may be indicated (displayed) in one grid by indicating (displaying) each water level information of the groundwater film filtration system 100a and the groundwater film filtration system 100b in a frame of one grid or the like.

In this case, the remote monitoring server 200 generates a water level and water quality information display image including the water level information display image and the water quality information display image, and transmits the generated water level and water quality information display image to the terminal device 300, when receiving the display request information transmitted from the terminal device 300 and the display request information includes information requesting the water level information display image and the water quality information display image.

For example, regions (grids) divided into grids may be displayed on the map, and water level information of the groundwater membrane filtration system 100a or water level information of the groundwater membrane filtration system 100b may be indicated (displayed) in each displayed grid, or water level information or water quality information may be indicated (displayed) in each frame and inside of the grid.

Further, for example, regions (meshes) divided into meshes of different sizes may be displayed on the map according to the shape of the water vein, and water level information of the groundwater film filtration system 100a or water level information of the groundwater film filtration system 100b may be indicated (displayed) on each displayed mesh, or water level information or water quality information may be indicated (displayed) in each frame and inside of the mesh.

For example, regions (meshes) divided into meshes may be displayed on a map, and two or more items may be indicated (displayed) in a frame of one mesh by indicating (displaying) water level information of the groundwater film filtration system 100a, water level information of the groundwater film filtration system 100b, or the like in each displayed mesh.

For example, in the case where the water quality information of the underground water membrane filtration system 100a or the water quality information of the underground water membrane filtration system 100b is indicated (displayed), the difference from the standard required for the area may be indicated (displayed) in each frame and the inside of the mesh.

In order to easily grasp the information of the water source, the same standard may be set in a plurality of areas, or the same standard may be set in all the areas. In the plurality of region selections, known information such as a river, an underground water vein, and the like may be used according to purposes.

Here, the predetermined date and time may be set to the time of drawing, for example. Further, the difference between the items measured at the present time (indicating the water quality information or the like) and the items measured at the present time may be indicated (displayed). Here, as detailed examples of the items, a water level of a water source, a water quality of the water source, a mark of the water source, and the like can be given.

Further, the case where the remote monitoring server 200 generates the display screen information based on the stored measurement information has been described, but the present invention is not limited to this example. For example, the remote monitoring server 200 may receive measurement information transmitted from the monitoring apparatus 112 and generate display screen information without storing the received measurement information. With this configuration, the process of storing can be omitted, and therefore, the process can be simplified.

In the above-described embodiment and modification, the case where the quality of the membrane-filtered water is measured in the underground water membrane filtration system 100 has been described, but the present invention is not limited to this example.

The remote monitoring system 2 includes: an underground water membrane filtration system 100c, an underground water membrane filtration system 100d, a remote monitoring server 200a, and a terminal device 300 a. The underground water membrane filtration system 100c, the underground water membrane filtration system 100d, the remote monitoring server 200a, and the terminal device 300a are connected via a communication network such as the internet or a mobile phone network.

The underground water membrane filtration system 100c and the underground water membrane filtration system 100d are distributed water channel systems that can be installed in a water source such as a well and change underground water into safe and safe drinking water by membrane filtration treatment. The groundwater membrane filtration system 100c and the groundwater membrane filtration system 100d measure the water level of the water source and the elevation of the ground surface where the water source is present, periodically or aperiodically. Further, the groundwater film filtration system 100c and the groundwater film filtration system 100d periodically or aperiodically acquire information indicating an operation state of a suction pump provided in a water source.

The groundwater membrane filtration system 100c and the groundwater membrane filtration system 100d periodically or aperiodically transmit measurement information including information on the water level of a measured water source (hereinafter referred to as "water level information"), information on the elevation of the ground surface where the water source is present (hereinafter referred to as "elevation information"), and information indicating the operation state of the suction pump (hereinafter referred to as "operation state information") to the remote monitoring server 200 a.

When receiving the measurement information transmitted from the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, the remote monitoring server 200a associates and stores the water level information, the elevation information, and the operation state information included in the measurement information.

In addition, the remote monitoring server 200a generates an image indicating (displays) either or both of the stored water level information and the elevation information. Hereinafter, an image showing (displaying) the water level information and the elevation information is referred to as a "water level elevation information display image", an image showing (displaying) the water level information is referred to as a "water level information display image", and an image displaying (showing) the elevation information is referred to as an "elevation information display image".

When receiving the display request information transmitted from the terminal device 300a and the display request information includes information requesting a water level elevation information display image, the remote monitoring server 200a generates a water level elevation information display image and transmits the generated water level elevation information display image to the terminal device 300 a.

The display request information includes information requesting display of any one of the water level elevation information display image, the water level information display image, and the elevation information display image. When the terminal device 300a receives any one of the water level elevation information display image, the water level information display image, and the elevation information display image transmitted by the remote monitoring server 200a for the display request information, any one of the received water level elevation information display image, the water level information display image, and the elevation information display image is displayed.

Hereinafter, the underground water membrane filtration system 100c and the underground water membrane filtration system 100d will be referred to as the underground water membrane filtration system 100. The same applies to each configuration of the underground water membrane filtration system 100.

(underground water membrane filtration system)

Fig. 2 can be applied to a schematic configuration of the underground water membrane filtration system. The underground water membrane filtration system 100 includes: a groundwater draw system 102, a raw water tank 104, a pre-filter 106, a membrane filter 108, a treated water tank 110, a monitoring device 112a, and a water collection tank 116.

The groundwater drawn by the groundwater draw system 102 is stored in a raw water tank 104. The pre-filter 106 filters the groundwater drawn by the groundwater draw system 102 to the extent that it is typically potable as a pre-treatment such as sand filtration. The membrane filter 108 further treats the water pretreated with the pre-filter 106 with various filters to produce safer drinking water. Specifically, the membrane filter 108 removes bacteria or protozoa such as O-157 or Cryptosporidium, which are causative agents of food poisoning, from the water pretreated by the pre-filter 106. The treatment water tank 110 stores water from which bacteria and protozoa have been removed by the membrane filter 108.

The monitoring device 112a continuously measures and records the concentration of residual chlorine in the water stored in the treated water tank 110. The monitoring device 112a automatically stops the underground water membrane filtration system 100 when the measurement result of the residual chlorine concentration indicates an abnormality.

The monitoring device 112a transmits the measurement result of the concentration of the residual chlorine in the water to the remote monitoring server 200 a. The sump 116 stores water stored in the processing tank 110 and public water supply.

(underground water drawing system)

Fig. 12 is a schematic diagram showing an example of the groundwater pumping system according to the second embodiment. The groundwater drawing system 102a includes: a well 11, a suction pump 12 for sucking groundwater W flushed in the well 11, a suction pipe 13, a water level gauge 19, and an elevation gauge 20.

The well 11 has a gas impermeable protective pipe 16 inserted into an excavation hole H excavated from the ground G downward to the aquifer X. The protection pipe 16 is a bottomed cylindrical pipe for protecting the excavated hole H from earth and sand falling or the like. A water intake port 16a for sucking groundwater in the aquifer X into the protection pipe 16 is formed near the bottom of the protection pipe 16 at a position of the aquifer X when inserted into the excavation hole H. A metal mesh 17 for preventing sand or the like from entering the protective pipe 16 is attached to the intake port 16 a. The term "gas impermeability" means that gas does not permeate through the soil such as the aquifer X from the protective tube 16.

The water pump 12 and the water pumping pipe 13 may use a well-known pump and a well-known water pumping pipe.

The water level gauge 19 measures the level of groundwater W flushed in the well. An example of the water level gauge 19 is a bubble type water level gauge. The bubble type water level gauge calculates the water level by measuring the pressure required to send bubbles to the water bottom by a bubble tube having an open end disposed on the water bottom. The water level gauge 19 transmits water level information including the water level measurement result of the groundwater W to the monitoring device 112 a.

The level gauge 20 measures the level of the ground G near the location where the well 11 is excavated. Examples of the altimeter 20 are a barometric altimeter, a radio altimeter, and the like. The level gauge 20 sends level information including the level measurement to the monitoring device 112 a.

(monitoring device)

Fig. 13 shows an example of a monitoring device according to a second embodiment. The monitoring device 112a includes: a communication unit 150a, a control unit 160a, a storage unit 170a, and a bus 180a such as an address bus and a data bus for electrically connecting the above-described components as shown in fig. 13.

The communication section 150a is realized by a communication module. The communication unit 150a communicates with the remote monitoring server 200a via the communication network 50.

The control Unit 160a is configured by an arithmetic Processing device such as a CPU (Central Processing Unit), and functions as the acquisition Unit 162a, the determination Unit 164a, the generation Unit 166a, and the Processing control Unit 168a by executing a program 172a stored in the storage Unit 170 a.

The acquisition unit 162a acquires the measurement result of the concentration of residual chlorine in the water stored in the treated water tank 110. When the acquisition unit 162a acquires the measurement result of the concentration of the residual chlorine in the water stored in the treated water tank 110, the measurement result of the concentration of the residual chlorine in the water stored in the treated water tank 110 is output to the determination unit 164 a.

When the acquisition unit 162a acquires information indicating the operation state of the water pump 12 from the water pump 12, the information indicating the operation state of the water pump 12 is output to the generation unit 166 a.

When the determination unit 164a obtains the measurement result of the residual chlorine concentration in the water stored in the treated water tank 110 output from the acquisition unit 162a, the residual chlorine concentration in the water is compared with the residual chlorine concentration threshold. The determination unit 164a outputs a determination result including a comparison result between the residual chlorine concentration in the water and the residual chlorine concentration threshold value to the process control unit 168 a.

When the generation unit 166a acquires the water level information, the elevation information, and the operation state information output by the acquisition unit 162a, it generates measurement information including the water level information, the elevation information, and the operation state information, and measurement information including identification information of a water source from which the water level information, the elevation information, and the operation state information are obtained. An example of the identification information of the water source is identification information such as ID of the groundwater membrane filtration system 100. When the generation unit 166a generates the measurement information, the measurement information is transmitted from the communication unit 150a to the remote monitoring server 200 a.

The processing controller 168a acquires the determination result output by the determination unit 164 a. When the determination result includes information indicating that the residual chlorine concentration in the water is equal to or higher than the residual chlorine concentration threshold, the treatment control unit 168a continues the treatment of the underground water membrane filtration system 100. On the other hand, when the determination result includes information indicating that the residual chlorine concentration in the water is lower than the residual chlorine concentration threshold value, the process control unit 168a may perform a predetermined error process. Specifically, when the determination result includes information indicating that the residual chlorine concentration in the water is lower than the residual chlorine concentration threshold value, the process control unit 168a stops the process of the underground water membrane filtration system 100 and sounds an alarm.

The storage unit 170a is implemented by a storage device such as a nonvolatile memory. The storage unit 170a stores a program 172 a.

(remote monitoring server)

Fig. 14 shows an example of a remote monitoring server according to the second embodiment. The remote monitoring server 200a includes: a communication unit 250a, a control unit 260a, a storage unit 270a, and a bus 290a such as an address bus and a data bus for electrically connecting the above-described components as shown in fig. 14.

The communication unit 250a communicates with the monitoring apparatus 112a and the terminal apparatus 300a via the communication network 50. The communication unit 250a receives the measurement information transmitted by the monitoring apparatus 112 a. When the communication unit 250a receives the measurement information, it outputs the measurement information to the control unit 260 a.

Further, the communication unit 250a receives the display request information transmitted from the terminal device 300. When the communication unit 250a receives the display request information, the display request information is output to the control unit 260 a. When the communication unit 250a acquires display screen information including any one of the water level elevation information display image, the water quality information display image, and the elevation information display image output by the control unit 260a in response to the display request information, the display screen information is transmitted to the terminal device 300 a.

The control unit 260a is configured by, for example, an arithmetic processing device, and functions as the storage processing unit 262a, the display image generation unit 264a, and the analysis unit 266a by executing the program 272a stored in the storage unit 270 a.

When the storage processing part 262a acquires the measurement information output by the communication part 250a, the water level information, the elevation information, the operation state information, and the identification information of the water source from which the water level information, the elevation information, and the operation state information are obtained, which are included in the measurement information, are acquired. When the storage processing part 262a acquires the water level information, the elevation information, the operation state information, and the identification information of the water source, the water level information, the elevation information, and the operation state information are stored in the measurement information table 274a of the storage part 270a in association.

(measurement information meter)

Fig. 15 shows an example of the measurement information table. The measurement information table 274a stores the date and time of the acquired measurement information, the water level information, the elevation information, and the operation state information included in the measurement information in association with the identification information of each water source such as the groundwater membrane filtration system 100. In the example shown in fig. 15, the acquisition date and time "2016.11.1010: 00 ", water level information" aaa "of the groundwater membrane filtration system 100c, water quality information" xxx "and operation state information" ON "are associated.

The display image generation unit 264a acquires the display request information output by the communication unit 250 a.

When the display request information includes information requesting a water level elevation information display image, the display image generation unit 264a refers to the measurement information table 274a and acquires information indicating either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and water level information and elevation information stored in association with either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d.

When the display image generating part 264a acquires information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, and water level information and elevation information stored in association with either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, a water level elevation information display image is generated which displays information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, the water level information, and the elevation information.

When the display request information includes information requesting a water level information display image, the display image generating unit 264a refers to the measurement information table 274a and acquires information indicating either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and water level information stored in association with either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d.

When the display image generating part 264a acquires information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and water level information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, a water level information display image is generated which displays information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and the water level information.

When the display request information includes information requesting an elevation information display image, the display image generation unit 264a refers to the measurement information table 274a and acquires information indicating either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and elevation information stored in association with either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d.

When the display image generation unit 264a acquires information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and altitude information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, it generates an altitude information display image that displays the information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and the altitude information.

When any one of the water level elevation information display image, the water level information display image, and the elevation information display image is generated by the display image generating unit 264a, the display screen information including any one of the water level elevation information display image, the water level information display image, and the elevation information display image is output to the communication unit 250 a. When drawing water, particularly underground water and lake water, the monitoring interval is preferably shortened as much as possible because the water level drops in minutes. Specifically, the display image generator 264a preferably updates any one of the water level elevation information display image, the water level information display image, and the elevation information display image for a period shorter than five minutes, and more preferably updates at least once every 2 minutes.

The analysis unit 266a acquires the measurement information stored in the measurement information table 274a of the storage unit 270 a. When the analysis unit 266a acquires the measurement information, the ground settlement is predicted by analyzing the water level information included in the measurement information.

Specifically, the analyzer 266a stores information indicating the initial water level (still water level), and calculates a value obtained by subtracting the initial water level from the acquired water level information. Here, as the initial water level, a water level of a standard date and time may be used. The analysis unit 266a determines the risk of foundation settlement from the subtracted value. For example, when the value of the subtraction is-5 m or more, "risk 1" indicating the lowest risk is set; when the value of the subtraction is-10 m or more and less than-5 m, "risk 2" indicating the second lowest risk; if the value of the subtraction is less than-10 m, "risk 3" indicating the third lowest risk is set. The analysis unit 266a may acquire elevation information included in the measurement information, and verify the prediction by checking whether or not the ground subsidence occurs from the elevation information.

Here, the relationship between the ground water level and the foundation settlement will be described. When the groundwater is pumped up at an appropriate pumping amount, the pumping amount of the groundwater and the holding amount are balanced, and therefore, a rapid water level decrease is unlikely to occur. In this case, voids and the like are not likely to be generated in the ground layer in the groundwater basin cycle, and the foundation is not likely to be settled.

Conversely, when the pumping and conserving quantities of groundwater are out of balance, a specific change in groundwater level will be measured: the groundwater level is lowered by excessive pumping or the like, and even if the measurement is performed for a certain time after pumping, the groundwater level (still water level) is not restored to the initial value, or the water level in pumping (dynamic water level) is gradually lowered. When the water level information acquired from the water level gauge 19 is detected, it is possible to determine that the risk of ground settlement on the ground surface exists in the water source for which the water level information is measured.

Therefore, the analyzer 266a stores information indicating the initial water level (still water level), and calculates a value obtained by subtracting the initial water level from the acquired water level information. The analysis unit 266 determines the risk of foundation settlement based on the value of the subtraction. The analysis unit 266a then determines whether the pumping amount and the holding amount of the groundwater are out of balance based on the value of the subtraction, thereby analyzing the cause of the foundation settlement.

The analyzer 266a may acquire time-series data of water level information from the measurement information stored in the measurement information table 274a of the storage 270 a. The analyzer 266a may acquire time-series data of the daily minimum water level from the time-series data of the water level information, and perform statistical processing on the acquired time-series data of the daily minimum water level.

Specifically, the analyzer 266a may calculate the change rate of the acquired time-series data of the daily minimum water level. Then, the analyzer 266a calculates the time period from the initial water level to risk 1. Furthermore, the analyzer 266a may predict the period from risk 1 to risk 2, and further predict the period from risk 2 to risk 3, based on the calculation result of the period from the initial water level to risk 1.

The analyzer 266a may store a threshold value of the minimum water level, and may notify the user by issuing an alarm when the acquired water level information does not reach the threshold value of the minimum water level.

The storage unit 270a is implemented by a storage device such as a nonvolatile memory. The storage unit 270a stores a program 272a and a measurement information table 274 a.

In step S2012, the control unit 360a of the terminal device 300a activates the application 376a by the user operating the operation unit 385a to activate the application 376 a. After the application 376a is started, when the user performs an operation to request the operation unit 385a to display any one of the water level elevation information display image, the water level information display image, and the elevation information display image, the control unit 360a generates display request information including information requesting display of any one of the water level elevation information display image, the water level information display image, and the elevation information display image.

In the above-described embodiment, the case where the remote monitoring server 200a generates any one of the water level elevation information display image including the water level information and the elevation information, the water level information display image including the water level information, and the elevation information display image including the elevation information has been described, but the present invention is not limited to this example. For example, the remote monitoring server 200a may acquire the operation state information in addition to information representing either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and water level information and elevation information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d.

In addition, the remote monitoring server 200a may acquire operation state information in addition to information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and water level information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d.

For example, the remote monitoring server 200a may also send an email containing the predicted foundation settlement result to the stakeholder. With this configuration, even if no person is present on the site, the person can grasp the risk.

According to the remote monitoring system of the embodiment, the monitoring apparatus 112a included in the groundwater membrane filtration system 100 acquires water level information including a water level measurement result using the water level gauge 19, elevation information including an elevation measurement result using the elevation gauge 20, and operation state information of the water pump 12 from the water pump 12 provided in a water source. When the monitoring device 112a acquires the water level information, the elevation information, and the operation state information, the measurement information including the water level information, the elevation information, the operation state information, and the identification information of the water source is transmitted to the remote monitoring server 200 a.

Further, by arranging the groundwater levels in time series, either or both of the change in the water level of the well and the change in the elevation can be dynamically grasped. For example, by determining whether or not a change in the water level of groundwater has occurred by referring to the water level information display image, it is possible to predict whether or not there is a risk of foundation settlement. In addition, when there is a risk of ground subsidence, it is possible to verify the prediction by referring to the altitude information display image of the predicted location and confirming whether or not ground subsidence has occurred.

(modification 1 thereof)

In the remote monitoring system according to the modified example, the water level gauge 19 measures the still water level and the moving water level of the water source. Then, measurement information including water level information such as a still water level measurement result and a dynamic water level measurement result measured by the water level gauge 19, elevation information, and identification information of the water source is transmitted to the monitoring device 112 a.

When the remote monitoring server 200a receives the measurement information transmitted from the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, the water level information and the identification information of the elevation information water source included in the measurement information are acquired. When the remote monitoring server 200a acquires the water level information, the elevation information, and the identification information of the water source, the water level information, the elevation information, and the identification information of the water source are associated and stored.

The remote monitoring server 200a generates display image information that displays either or both of the stored water level information and elevation information.

When receiving the display request information transmitted from the terminal device 300a and the display request information includes information requesting a water level elevation information display image, the remote monitoring server 200a generates a water level elevation information display image and transmits the generated water level elevation information display image to the terminal device 300 a. Specifically, when the remote monitoring server 200a acquires information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, and water level information (still water level, moving water level) and elevation information stored in association with either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, a water level elevation information display image is generated which displays information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, the water level information (still water level, moving water level), and the elevation information.

In addition, when receiving the display request information transmitted from the terminal device 300a and the display request information includes information requesting a water level information display image, the remote monitoring server 200a generates a water level information display image and transmits the generated water level information display image to the terminal device 300 a. Specifically, when the remote monitoring server 200a acquires information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d and water level information (still water level, moving water level) stored in association with either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, a water level elevation information display image is generated which displays information indicating either or both of the underground water film filtration system 100c and the underground water film filtration system 100d and the water level information (still water level, moving water level).

(operation of remote monitoring System)

Fig. 18 can be applied to a sequence diagram showing an example of the operation of the remote monitoring system. However, in step S2005, the acquisition unit 162a of the monitoring device 112a acquires the operation state information of the water pump 12 from the water pump 12 in a cycle shorter than 2 minutes. In step S2006, the acquiring unit 162a of the monitoring device 112a acquires the water level measurement result of the water source from the water level gauge 19 in a cycle shorter than 2 minutes.

Even in the case of using the water level measurement result of the water source of the water level gauge 19 and measuring the start/stop signal of the water pump 12, for example, when the water level gauge 19 measures the water level of the water source for a period of 1 hour unit, 1 day unit or longer like an observation well, it is difficult to capture the activity of the water pump 12 that is not periodically started or stopped, so that it is difficult to judge whether the measured water level is a still water level or a moving water level. In this way, by acquiring the operation state information of the suction pump 12 and the water level measurement result of the water source in a cycle shorter than 2 minutes, the acquisition unit 162a can grasp the still water level and the moving water level with high accuracy.

In the above-described embodiment, the case where remote monitoring server 200a generates any one of the water level elevation information display image including the water level information and the elevation information, the water level information display image including the water level information, and the elevation information display image including the elevation information has been described, but the present invention is not limited to this example. For example, the remote monitoring server 200a may acquire the operation state information in addition to information representing either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and water level information and elevation information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d. Also, the remote monitoring server 200 may also generate a water level elevation information display image displaying information representing either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, the water level information, the elevation information, and the operation state information.

In addition, the remote monitoring server 200a may acquire operation state information in addition to information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and water level information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d. Also, the remote monitoring server 200a may also generate a water level information display image displaying information representing either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, the water level information, and the operation state information.

In addition, the remote monitoring server 200a may acquire operation state information in addition to information indicating either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and altitude information stored in association with either or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100 d. Also, the remote monitoring server 200 may also generate an elevation information display image displaying information representing either or both of the underground water film filtration system 100c and the underground water film filtration system 100d, the elevation information, and the operation state information.

According to the remote monitoring system 1 of the modification, the remote monitoring server 200a can generate display screen information such as a water level elevation information display image and a water level information display image based on the display request information transmitted from the terminal device 300 a. Specifically, the remote monitoring server 200a acquires the water level information (still water level or moving water level) and the elevation information stored in the measurement information table 274a in the case where the display request information is indicated to include information of the water level elevation information display image, and generates an elevation information display image that displays information indicating either one or both of the underground water film filtration system 100c and the underground water film filtration system 100d, the water quality information (still water level or moving water level), and the elevation information.

In addition, the remote monitoring server 200a acquires the water level information (still water level or running water level) stored in the measurement information table 274a in the case where the information indicating the water level information display image is included in the display request information, and generates a water level information display image that displays information indicating either one or both of the underground water membrane filtration system 100c and the underground water membrane filtration system 100d and the water quality information (still water level or running water level).

With such a configuration, it is possible to acquire information in near real time as compared with the case of using information measured in a general observation well. By being able to acquire near real-time information, it is possible to capture changes in either or both of the still water level and the moving water level with high accuracy.

In addition, information of either or both of the level (still water level or dynamic water level) and the elevation of groundwater in one or more sites can be automatically and remotely monitored in a unified manner. Further, by arranging the groundwater levels in time series, either or both of the change in the water level of the well and the change in the elevation can be dynamically grasped. For example, whether or not there is a risk of foundation settlement can be predicted by determining whether or not there is a change in the static water level or the kinetic water level with reference to the water level information display image. In addition, when there is a risk of foundation settlement, it is possible to provide a display image of elevation information with reference to the predicted location, and verify the prediction by confirming whether or not foundation settlement occurs.

(modification example (2 thereof))

The remote monitoring system of the modification includes a remote monitoring server 400a instead of the remote monitoring server 200a of the foregoing embodiment.

The remote monitoring server 400a stores the threshold value of the lowest water level per day and the threshold value of the highest water level per day for each of the underground water membrane filtration systems 100c and the underground water membrane filtration systems 100 d. When the remote monitoring server 400a stores the measurement information transmitted from the groundwater film filtration system 100c and the groundwater film filtration system 100d, water level information contained in the measurement information is acquired.

When the water level information is acquired while the water pump 12 is operating, the remote monitoring server 400a continues the operation of the water pump 12 until the water level is lower than the daily minimum water level threshold. In addition, the remote monitoring server 400a continues to stop the operation of the water pump 12 until the water level reaches the maximum daily water level threshold or more, in a case where the water level information is acquired in a state where the water pump 12 is not operating.

(remote monitoring server)

Fig. 19 shows an example of a remote monitoring server according to a modification. The remote monitoring server 400a includes: a communication unit 450a, a control unit 460a, a storage unit 470a, and a bus 490a such as an address bus and a data bus for electrically connecting the above-described components as shown in fig. 19.

The communication unit 250a, the storage unit 270a, the display 280a, and the operation unit 285a of the remote monitoring server 200a described with reference to fig. 14 can be applied to the communication unit 450a, the storage unit 470a, the display 480a, and the operation unit 485 a.

The control unit 460a is configured by, for example, an arithmetic processing device, and functions as a storage processing unit 462a, a display image generation unit 464a, and a control unit 466a by executing the program 472a stored in the storage unit 470 a.

The storage processing unit 262a of the remote monitoring server 200a described with reference to fig. 14 can be applied to the storage processing unit 462 a.

The display image generating unit 264a of the remote monitoring server 200a described with reference to fig. 14 can be applied to the display image generating unit 464 a.

The controller 466a stores the threshold value of the lowest water level per day and the threshold value of the highest water level per day for each of the underground water membrane filtration systems 100c and the underground water membrane filtration systems 100 d. The controller 466a acquires the water level information stored in the measurement information table 474a of the storage unit 470 a. The control unit 466a operates the water pumps 12a predetermined number of times, a predetermined time, and a predetermined number of times within a predetermined time. Specifically, the control unit 466a operates the water pump 12 at an appropriate water pumping amount, which is previously grasped, once a day, 24 hours to 60 minutes. The controller 466a stops the water pump 12 for a certain time after the operation thereof, and performs a water pumping test that is periodically performed. The controller 466a periodically confirms that the groundwater use balance is properly maintained by returning the water level after the water pumping test to the initial water level and comparing and collating the water level with the result of the previous water pumping test.

When the water level information acquired while the water pump 12 is operating is higher than the daily minimum water level threshold value, the control unit 466a continues the operation of the water pump 12 until the water level reaches the daily minimum water level threshold value. In addition, the remote monitoring server 400a continues to stop the operation of the water pump 12 until the water level reaches the daily maximum water level threshold or higher, when the water level information acquired in the state where the water pump 12 is not operating is lower than the daily maximum water level threshold.

According to the remote monitoring system of the modification, when the remote monitoring server 400a stores the measurement information transmitted from the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, the water level information included in the measurement information is acquired. When the remote monitoring server 400a obtains the water level information included in the measurement information, the start and stop of the water pump are controlled according to the water level information.

With this configuration, groundwater can be pumped up with an appropriate amount of pumped water.

In the above-described embodiment and modification, the well has been described as an example of the water source, but the present invention is not limited to this example. For example, the present invention can be applied to a river. In this case, the system is applied to the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, and is a distributed water channel system which is installed in a water source such as a river and changes river water into safe drinking water by membrane filtration treatment.

In the above-described embodiment and modification, the remote monitoring system 2 is provided with the underground water membrane filtration system 100c and the underground water membrane filtration system 100d, but the present invention is not limited to this example. For example, the number of underground water membrane filtration systems provided in the remote monitoring system 1 may be one, or may be three or more.

In the above-described embodiment and modification, the case where the remote monitoring server generates any one of the water level elevation information display image, the water level information display image, and the elevation information display image has been described, but the present invention is not limited to this example. For example, the remote monitoring server may further generate at least two of a water level elevation information display image, a water level information display image, and an elevation information display image.
