Description

The present invention relates to a water treatment system, a program, an information processing device, and a water treatment method.

Activated carbon and other materials have traditionally been used to combat the moldy odor of tap water, but the enormous cost involved has become an issue. As a result, methods known for suppressing the generation of substances that cause moldy odors include spraying copper sulfate into the water reservoir, or circulating the water in a water circulator installed in the reservoir to suppress the growth of the microorganisms that cause the moldy odor.

However, these suppression methods have the problem that they only have a limited effect. In other words, it is not possible to determine whether or not copper sulfate should be sprayed at the reservoir on-site, and suppression measures can only be taken after sampling the water and having an analytical laboratory detect the presence of the substances that cause the moldy odor. In addition, the chemicals must be sprayed widely within the reservoir, which requires huge chemical costs. Furthermore, the water can only be circulated in certain areas, and circulating it throughout the entire reservoir would be extremely costly.

Patent document 1 describes a system in which a water quality manager operates an unmanned aerial vehicle to collect water samples from aquaculture ponds and test the water quality of the ponds.

JP 2018-33418 A

However, even if the technology described in Patent Document 1 is used to detect the generation of moldy odor-causing substances using unmanned aerial vehicles, it is still not possible to implement suppression measures until the generation of moldy odor-causing substances is detected by an analysis laboratory located away from the site.

The purpose of the present invention, which was made in light of these circumstances, is to more simply and effectively suppress the generation of substances that cause mold odors.

FIG. 2 is a diagram showing yet another example of the configuration of a water treatment system according to an embodiment of the present invention.

The following describes an embodiment of the present invention with reference to the drawings. In each drawing, the same reference numerals indicate the same or equivalent components.

Figure 1 is a diagram showing an example of the configuration of a water treatment system 1 according to one embodiment of the present invention. The water treatment system 1 according to this embodiment acquires information about mold odor-causing substances that cause mold odors on the water surface or in the water of a reservoir, and takes measures to suppress the generation of the mold odor-causing substances based on the acquired information.

The water treatment system 1 shown in FIG. 1 includes a measurement drone 10, a countermeasure drone 20, and a server 30. The measurement drone 10 is an example of a first moving body. The countermeasure drone 20 is an example of a second moving body. The server 30 can communicate with the measurement drone 10 and the countermeasure drone 20 via a network 40. The network 40 is, for example, a network capable of wireless communication. The network 40 may also include a network capable of wireless communication and a network capable of wired communication.

The measurement drone 10 and the countermeasure drone 20 are mobile bodies capable of moving in the air, on the water's surface, or underwater. More specifically, the measurement drone 10 and the countermeasure drone 20 are mobile bodies capable of flying in the air, moving on the water's surface, or diving underwater, either remotely or autonomously. The measurement drone 10 and the countermeasure drone 20 are, for example, rotorcraft-type flying bodies, submersible-type mobile bodies, boat-type mobile bodies, etc.

The measurement drone 10 moves above the reservoir, on the surface of the reservoir's stored water, or underwater, either remotely or autonomously. Musty odor-causing substances include not only planktonic substances, but also benthic or epiphytic substances, and substances that live in the soil. In addition, as water quality differs depending on the depth, the concentration of the same substance may differ depending on the depth. For this reason, it is preferable for the measurement drone 10 to be able to move freely to any location on the surface or underwater in the reservoir without any restrictions on the positions or depths to which it can move (hereinafter sometimes referred to as "three-dimensional movement").

The sensor 11 is provided in the measuring drone 10 and is a measuring device that performs various measurements of moldy odor-causing substances on the water surface or underwater in the reservoir. For example, a fluorescent sensor can be used as the sensor 11. It is known that microorganisms that cause moldy odors generate fluorescent substances when active. By detecting the fluorescent substances generated by the microorganisms that cause moldy odors using a fluorescent sensor, it is possible to identify the location where the moldy odor-causing substances are generated. For example, a camera can be used as the sensor 11. By photographing the water surface and underwater of the reservoir water using a camera and analyzing the captured images, it is possible to identify the location where the moldy odor-causing substances are generated. For example, a water thermometer, a dissolved oxygen meter, etc. can be used as the sensor 11. The sensor 11 may include multiple measuring devices.

The measurement drone 10 transmits the measurement results of the sensor 11 and the position information (e.g., latitude and longitude) of the measurement drone 10 at the time of measurement by the sensor 11 to the server 30 via the network 40. The position information of the measurement drone 10 can be obtained, for example, by receiving a GPS (Global Positioning System) signal. When the measurement drone moves underwater, the position information may include water depth in addition to latitude and longitude.

The countermeasure drone 20, either remotely or autonomously, flies over the reservoir, on the surface of the reservoir's stored water, or underwater, and takes measures to suppress the generation of substances that cause mold odors, such as spraying copper sulfate or emitting ultrasound using an ultrasonic generator.

The server 30 is an information processing device capable of communicating with the measurement drone 10 and the countermeasure drone 20 via the network 40. The server 30 receives the measurement results of the sensor 11 and the position information of the measurement drone 10 transmitted from the measurement drone 10. The server 30 acquires information about the moldy odor-causing substances based on the measurement results of the sensor 11 and the position information of the measurement drone 10. The server 30 determines countermeasures to suppress the generation of the moldy odor-causing substances based on the acquired information about the moldy odor-causing substances, and transmits a dispatch command to the countermeasure drone 20 to implement the determined countermeasures.

As shown in FIG. 1, the server 30 includes an acquisition means 2 and a determination means 3. The acquisition means 2 and the determination means 3 can be realized, for example, by a computer (for example, a personal computer) including a CPU (Central Processing Unit) and a memory. When the acquisition means 2 and the determination means 3 are realized by a computer, the acquisition means 2 and the determination means 3 are realized by storing a program according to this embodiment in the memory and having the CPU read and execute the stored program.

The acquisition means 2 is a means for acquiring information about moldy odor-causing substances in the reservoir by measurement using the measurement drone 10. The acquisition means 2 stores the measurement results of the sensor 11 and the position information of the measurement drone 10 received from the measurement drone 10 in memory. The acquisition means 2 then analyzes the measurement results of the sensor 11 and the position information of the measurement drone 10 to acquire information about the moldy odor-causing substances. For example, the acquisition means 2 acquires information about the moldy odor-causing substances, such as the probability of occurrence of the moldy odor-causing substances, the concentration of the moldy odor-causing substances, and the area where the moldy odor-causing substances occur.

The acquisition means 2, for example, stores in advance a relational equation between the measurement results of the sensor 11 and the concentration of the moldy odor-causing substance (or the amount of the moldy odor-causing substance). The acquisition means 2 calculates the concentration of the moldy odor-causing substance (or the amount of the moldy odor-causing substance) from the measurement results of the sensor 11 based on the relational equation, and determines that a moldy odor is occurring when the calculated value reaches a predetermined concentration (or amount). Then, when the acquisition means 2 determines that a moldy odor is occurring, it identifies the area where the moldy odor is occurring based on the position information of the measurement drone 10.

As described above, when the measuring drone 10 moves three-dimensionally in the reservoir, the acquisition means 2 may acquire three-dimensional measurement results by the sensor 11 (measurement results by the sensor 11 acquired as the measuring drone 10 moves three-dimensionally in the reservoir). This enables more detailed measurements to be made not only of the water surface of the reservoir water, but also of the moldy odor-causing substances occurring in the water, and more detailed information can be acquired, such as the area in the water where the moldy odor-causing substances occur and the concentration of the moldy odor-causing substances.

The determination means 3 is a means for determining measures to be taken by the countermeasure drone 20 to suppress the generation of the moldy odor-causing substances based on the information on the moldy odor-causing substances acquired by the acquisition means 2, and for causing the countermeasure drone 20 to execute the determined measures.

The determination means 3 determines the position where a countermeasure to suppress the generation of the moldy odor-causing substance is to be implemented from the generation area of the moldy odor-causing substance acquired by the acquisition means 2, for example. For example, the determination means 3 may determine the center of the generation area of the moldy odor-causing substance as the position where the countermeasure is to be implemented. The determination means 3 may also determine the position where the countermeasure is to be implemented by taking into account wind direction, water currents, etc.

The determining means 3 determines the most suitable countermeasure from among various known countermeasures for suppressing the generation of moldy odor-causing substances, taking into consideration the state of the reservoir and the advantages of each countermeasure. For example, when the reservoir water is used for purposes other than tap water (e.g., agricultural water), it may be determined that a countermeasure of irradiating ultrasonic waves with an ultrasonic generator or a countermeasure of recovering water with a strainer or the like is preferable to a countermeasure of spraying copper sulfate, taking into consideration the possibility that copper sulfate may remain in the stored water. Also, when moldy odor-causing substances are generated over a wide area, a countermeasure of irradiating ultrasonic waves may increase the power consumption of the ultrasonic generator, and a countermeasure of recovering water with a strainer or the like has a limit to the amount of recovery, so it may be determined that a countermeasure of spraying copper sulfate, which allows for a quick response over a wide area, is preferable.

The decision means 3 sends a command to the countermeasure drone 20 to execute the determined countermeasure to suppress the generation of the moldy odor-causing substance.

In this way, the acquisition means 2 acquires information about the substances that cause moldy odors in the reservoir from the measurement results of the sensor 11 mounted on the measurement drone 10. Therefore, information about the substances that cause moldy odors can be easily acquired without the manager or other person having to go to the reservoir.

The determination means 3 determines countermeasures for suppressing the generation of the moldy odor-causing substances based on the information about the moldy odor-causing substances acquired by the acquisition means 2, and has the countermeasure drone 20 execute the determined countermeasures. Therefore, countermeasures for suppressing the generation of the moldy odor-causing substances can be easily executed without the need for a manager or the like to go to the reservoir. Furthermore, because the countermeasures are executed by the countermeasure drone 20, the countermeasures can be executed at any location that is effective in suppressing the generation of the moldy odor-causing substances. Therefore, the generation of the moldy odor-causing substances can be more effectively suppressed.

Therefore, the water treatment system 1 according to this embodiment, which is equipped with an acquisition means 2 and a determination means 3, can more easily and efficiently suppress the generation of substances that cause mold odors.

Figure 2 is a sequence diagram showing an example of the operation of the water treatment system 1 according to this embodiment. In Figure 2, an example will be described in which the server 30 shown in Figure 1 includes an acquisition means 2 and a determination means 3.

The measurement drone 10 moves over the reservoir, on the surface of the reservoir's stored water, or underwater, and uses the sensor 11 to perform various measurements of substances that cause mold odors on the surface or underwater of the reservoir (step S11).

The measurement drone 10 transmits the measurement results of the sensor 11 and the position information of the measurement drone 10 to the server 30 via the network 40 (step S12).

The acquisition means 2 of the server 30 receives the measurement results of the sensor 11 and the position information of the measurement drone 10 transmitted from the measurement drone 10, and records them in memory (step S13). The acquisition means 2 then acquires information about the moldy odor-causing substances based on the measurement results of the sensor 11 and the position information of the measurement drone 10 (step S14). If the information about the moldy odor-causing substances acquired by the acquisition means 2 indicates that the moldy odor-causing substances are occurring in the reservoir or that the probability of the moldy odor-causing substances occurring is high (step S15), the decision means 3 determines measures to suppress the occurrence of the moldy odor-causing substances according to the concentration of the moldy odor-causing substances, the area of occurrence, etc. Then, the decision means 3 transmits a dispatch command to the countermeasure drone 20 to execute the determined countermeasure (step S16). The dispatch command includes position information about the position where the countermeasure is executed. The dispatch command also includes information about the countermeasure. For example, if the countermeasure is executed by spraying copper sulfate, the dispatch command includes the amount of copper sulfate to be sprayed.

When the countermeasure drone 20 receives the dispatch command sent from the server 30, it dispatches in accordance with the dispatch command (step S17) and carries out countermeasures (step S18).

The water treatment method in the water treatment system 1 according to this embodiment thus includes a step of acquiring information about the moldy odor-causing substances that cause the moldy odor in the reservoir by the measurement drone 10 (step S14), and a step of determining countermeasures for suppressing the generation of the moldy odor-causing substances by the countermeasure drone 20 based on the information about the moldy odor-causing substances and having the countermeasure drone 20 execute the determined countermeasures (step S15).

In the present embodiment, an example has been described in which the mobile body (measurement drone 10) for acquiring information about moldy odor-causing substances and the mobile body (countermeasure drone 20) for taking measures to suppress the generation of moldy odor-causing substances are separate mobile bodies, but the present invention is not limited to this. A single mobile body (drone) may have a function for acquiring information about moldy odor-causing substances and a function for taking measures to suppress the generation of moldy odor-causing substances. By having a single drone have a function for acquiring information about moldy odor-causing substances and a function for taking measures to suppress the generation of moldy odor-causing substances, measures can be implemented quickly when it is determined that measures are necessary.

In addition, in this embodiment, the countermeasure drone 20 is dispatched upon receiving a dispatch command and executes countermeasures, but the present invention is not limited to this. For example, the countermeasure drone 20 may move while following the measurement drone 10. By having the countermeasure drone 20 follow the measurement drone 10, countermeasures can be executed quickly when it is determined that countermeasures are necessary.

It may also be possible to select whether the countermeasure drone 20 will be dispatched in response to a dispatch command or will follow the measurement drone 10. For example, in a situation (season, weather, etc.) in which substances that cause moldy odors are likely to occur, the countermeasure drone 20 can follow the measurement drone 10 and quickly implement countermeasures if it is determined that countermeasures are necessary.

In addition, it is generally known that, in terms of water depth, the concentration of moldy odor-causing substances tends to be high at the bottom of the reservoir and in the area from the water surface to a depth of about 5 m. In terms of water level, it is also known that the generation of moldy odor-causing substances is greatly influenced by wind and the topography of the reservoir. Therefore, it is preferable to focus measurements on points where the concentration of moldy odor-causing substances tends to be high, or points that take wind and the reservoir into consideration.

For example, if there is no information about the water depth, topography, or wind in the reservoir, a rough measurement may be carried out first to identify locations in the entire reservoir where substances that cause moldy odors are likely to occur or where concentrations are likely to be high. After the rough measurement, it is preferable to carry out focused measurements in the identified locations or areas.

For example, when the measurement drone 10 is used to roughly measure the entire reservoir, the countermeasure drone 20 may be placed on standby so that it can be dispatched in response to a dispatch command. Also, when the measurement drone 10 is used to perform focused measurements, the countermeasure drone 20 may be configured to follow the measurement drone 10 so that countermeasures can be implemented quickly.

In this embodiment, the water treatment system 1 includes an acquisition means 2 that acquires information about mold odor-causing substances in a reservoir by measuring using a moving measurement drone 10, and a decision means 3 that determines measures to suppress the generation of mold odor-causing substances using a countermeasure drone 20 based on the information, and has the determined countermeasure drone 20 execute the measures.

By using a mobile object to obtain information about mold odor-causing substances and to take measures to suppress the generation of mold odor-causing substances, the generation of mold odor-causing substances can be more easily suppressed. Furthermore, by using a mobile object to take measures to suppress the generation of mold odor-causing substances, the measures can be carried out at any location suitable for suppressing the generation of mold odor-causing substances, so the generation of mold odor-causing substances can be more effectively suppressed. Therefore, according to the present invention, the generation of mold odor-causing substances can be more easily and effectively suppressed.

Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art would easily be able to make various modifications and corrections based on this disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present invention. For example, the functions included in each means, step, etc. can be rearranged so as not to cause logical inconsistencies, and multiple means and steps can be combined into one or divided. The above is merely one embodiment of the present invention, and it goes without saying that various modifications may be made within the scope of the claims.

It is also possible for each component or each means of the server 30 as an information processing device to be distributed among multiple information processing devices. It is also possible for at least one of the multiple information processing devices to be realized as a server connected to a network such as the Internet.

For example, the following arrangement may be used for the arrangement of each means in the measurement drone 10, countermeasure drone 20, and server 30.

For example, as shown in FIG. 3, the measurement drone 10 can be configured to include a sensor 11 and an acquisition means 2, and the server 30 can be configured to include a countermeasure means 3. In this case, the measurement drone 10 can send all acquired information (the measurement results of the sensor 11, the position information of the measurement drone 10, and the information related to the moldy odor-causing substances that is the analysis result) to the server 30, or the information sent to the server 30 can be selective, such as sending only the information related to the moldy odor-causing substances that is the analysis result.

Also, as shown in FIG. 4, the measurement drone 10 can be equipped with a sensor 11 and an acquisition means 2, the countermeasure drone 20 can be equipped with a decision means 3, and a configuration can be used in which a server 30 is not provided. In this case, the measurement drone 10 and the countermeasure drone 20 can communicate via a network 40, or can communicate directly via wireless communication or the like. Note that the information sent from the measurement drone 10 to the countermeasure drone 20 is the same as the configuration described with reference to FIG. 3.
