Below, a data management system, a data management method, and a data management program according to an embodiment of the present disclosure will be described in detail based on the drawings.

Embodiment 1.
FIG. 1 is a diagram showing an example of the overall configuration of a water treatment system according to the first embodiment. Water treatment system 100 according to the first embodiment includes a data management device 1 that implements a data management system, a first water purification plant 31, and a second water purification plant 32. The first water purification plant 31 and the second water purification plant 32 use the river 2 as a water source and purify raw water that is water taken in from the river 2. Note that the positions where each of the first water purification plant 31 and the second water purification plant 32 take in water are different. In the following explanation, the position where each water purification plant takes in water may be referred to as the water intake position. In FIG. 1, the water treatment system 100 includes two water purification plants, the first water purification plant 31 and the second water purification plant 32, but may include three or more water purification plants. That is, the number of water purification plants included in the water treatment system 100 may be plural.

The data management device 1 is capable of communicating with each of the first water purification plant 31 and the second water purification plant 32. The data management device 1 collects and manages measurement data output from various water quality sensors provided in each of the first water purification plant 31 and the second water purification plant 32. Furthermore, the data management device 1 has a function of estimating water quality at any position of the river 2 based on the collected measurement data. In the following explanation, this function may be referred to as a water quality estimation function. Details of the data management device 1 will be described later.

The first water purification plant 31 is provided on the upstream side of the river 2, and the second water purification plant 32 is provided on the downstream side of the river 2, that is, on the downstream side of the first water purification plant 31. Further, the first water purification plant 31 includes three types of water quality sensors A, B, and C, and the second water purification plant 32 includes two types of water quality sensors A and B. That is, the first water purification plant 31 includes a first number of water quality sensors, and the second water purification plant 32 includes a second number of water quality sensors different from the first number. Since the second water purification plant 32 does not include the water quality sensor C, there are fewer measurable water quality items than the first water purification plant 31. Note that in this embodiment, the water quality measured by water quality sensor A is referred to as water quality A. Similarly, the water quality measured by water quality sensor B is called water quality B, and the water quality measured by water quality sensor C is called water quality C.

Here, as shown in Figure 1, the first water purification plant 31 and the second water purification plant 32 use the river 2 as their water source, and since the water source is the same, there is no relationship between the properties of the water taken in by each water purification plant. be. Therefore, in the water treatment system 100, the data management device 1 uses the water quality estimation function to calculate the water quality C that cannot be measured at the second water purification plant 32 based on the water quality C measured at the first water purification plant 31. Perform the estimated complementary operation. The second water purification plant 32 acquires complementary data indicating the estimated result of water quality C from the data management device 1, and performs water purification using the acquired complementary data.

FIG. 2 is a diagram showing a configuration example of the data management device 1 according to the first embodiment. The data management device 1 includes a data acquisition section 11, a data registration section 12, a complementable data identification section 13, a complementable data notification section 14, a complementation request reception section 15, a supplementary data creation section 16, a supplementary data output section 17, and a storage section. 18 and a communication section 20. The storage unit 18 includes a water quality data storage unit 19A and an equipment data storage unit 18B. Note that in this embodiment, each component of the data acquisition section 11 to the communication section 20 shown in FIG. It may also be arranged in a distributed manner so that each section provided in each device cooperates with each other to operate as a data management system. For example, the storage unit 18 may be provided in a storage device, server, etc. external to the data management device 1, or the communication unit 20 may be implemented in a communication device external to the data management device 1. In other words, the data management system according to the present embodiment may be realized by the data management device 1 shown in FIG. 2 alone, or by a plurality of devices in which each component of the data management device 1 shown in FIG. 2 is distributed. It may be realized by

The data acquisition unit 11 acquires measurement data from the first water purification plant 31 and the second water purification plant 32. The measurement data that the data acquisition unit 11 acquired from the first water purification plant 31 is first measurement data, and the measurement data that the data acquisition unit 11 acquired from the second water purification plant 32 is second measurement data. The data registration unit 12 registers the measurement data acquired by the data acquisition unit 11 in the water quality data holding unit 19A. Registration here means storing the measurement data in the water quality data holding unit 19A.

The supplementable data specifying unit 13 specifies water quality items that can be estimated based on the measurement data held by the water quality data holding unit 19A. That is, the complementable data specifying unit 13 identifies complementable data that is measurement data that can be supplemented based on the measurement data held by the water quality data holding unit 19A. The complementable data notification unit 14 transmits the complementable data items specified by the complementable data specifying unit 13, that is, the water quality items that can be estimated by the data management device 1, to the first water purification plant 31 and the second water purification plant 31. The water purification plant 32 is notified.

The supplement request receiving unit 15 receives supplement requests from the first water purification plant 31 and the second water purification plant 32. The supplement request is a signal for requesting missing data among data on multiple water quality items used in water purification treatment. The complementary data creation unit 16 estimates the water quality item indicated by the complementary request received by the complementary request receiving unit 15, and creates data representing the estimation result as complementary data. The complementary data output unit 17 outputs the complementary data created by the complementary data creating unit 16 to the water purification plant that is the source of the complementary request.

The water quality data holding unit 19A of the storage unit 18 holds the measurement data acquired from each water purification plant by the data acquisition unit 11, which is a measurement data acquisition unit, as water quality data. Furthermore, the equipment data holding unit 19B of the storage unit 18 holds various information about each water purification plant that constitutes the water treatment system 100 as equipment data. The equipment data includes information on water quality sensors provided in each water purification plant, location information indicating where each water purification plant is installed, distances between water purification plants, shape and water depth of the river 2 that is the water source, and the like. The equipment data is used when the complementary data creation unit 16 estimates water quality based on the water quality data held by the water quality data storage unit 19A. It is assumed that each of the above pieces of information included in the equipment data is stored in advance in the equipment data holding unit 19B, but a configuration may be adopted in which part or all of the information included in the equipment data is acquired from each water purification plant. In such a configuration, for example, the data acquisition unit 11 operates as an equipment data acquisition unit to acquire necessary information from each water purification plant.

The communication unit 20 transmits and receives control signals and data signals to and from the first water purification plant 31 and the second water purification plant 32.

Next, the operation of the data management device 1 will be explained with reference to FIGS. 1 to 4. FIG. 3 is a flowchart showing an example of the operation of the data management device 1 according to the first embodiment. FIG. 4 is a diagram showing measurement data that the data management device 1 according to the first embodiment acquires from each water purification plant.

As shown in FIG. 3, the data management device 1 acquires measurement data from each water purification plant (step S11). Specifically, the data acquisition unit 11 acquires measurement data from the first water purification plant 31 and the second water purification plant 32, and the data registration unit 12 stores this in the water quality data holding unit 19A. In step S11, each of the first water purification plant 31 and the second water purification plant 32 may transmit measurement data every fixed period, or the data acquisition unit 11 may transmit the measurement data at each fixed period. The measurement data may be obtained by requesting the second water purification plant 32 to transmit data. In the present embodiment, as shown in FIG. Get data. In addition, in FIG. 4, the measurement data that the data management device 1 acquires from the water purification plant is represented by "○", and the measurement data that is not acquired from the water purification plant is represented by "x".

After acquiring the measurement data from each water purification plant, the data management device 1 then identifies data that can be supplemented and notifies each water purification plant of the data (step S12). The data that can be complemented is specified by the complementable data specifying unit 13, and the data to be complemented is notified to each water purification plant by the complementable data notification unit 14. In this embodiment, water quality A and water quality B are measured at the first water purification plant 31 and the second water purification plant 32, while water quality C is measured only at the first water purification plant 31. Therefore, the complementable data specifying unit 13 determines that the data of water quality C is data that can be complemented. The complementable data notification unit 14 may notify both the first water purification plant 31 and the second water purification plant 32 that the water quality C data can be complemented, or may notify both the first water purification plant 31 and the second water purification plant 32 that the water quality C data is not provided with the water quality sensor C. You may make it notify only the 2nd water purification plant 32 which cannot measure.

In addition, in the example shown in FIG. 1, there are two water treatment plants that take in water from the river 2, but if there are three or more water treatment plants, the complementary data identification unit 13 measures only at some of the water treatment plants. It is determined that the water quality data in the item is data that can be supplemented. Furthermore, when there is a plurality of data that can be complemented, the complementable data notification unit 14 notifies each water purification plant of all the data that can be complemented.

After notifying data that can be complemented, the data management device 1 checks whether a data complementation request has been received (step S13). If a certain period of time has elapsed without receiving a data complementation request after notification of data that can be complemented (step S13: No), the data management device 1 returns to step S11 and continues the operation. On the other hand, if the data management device 1 receives a data supplementation request before a certain period of time has elapsed since the notification of data that can be supplemented (step S13: Yes), the data management device 1 creates and transmits supplementary data (step S14). ). In step S13, the complementation request reception unit 15 checks whether a data complementation request has been received. In step S14, the complementary data creation unit 16 creates complementary data of the water quality requested by the data complementation request, and the complementary data output unit 17 transmits the complementary data to the water purification plant that is the source of the data complementation request.

In this embodiment, there is a possibility that supplementary data of water quality C may be requested from the second water purification plant 32 which is not equipped with water quality sensor C. When supplementary data of water quality C is requested from the second water purification plant 32, the supplementary data creation unit 16 uses the measured data of water quality C acquired from the first water purification plant 31 by the data acquisition unit 11 and the data of the first water purification plant 31. The water quality C of the water taken in at the second water purification plant 32 is estimated based on the distance to the second water purification plant 32 and the speed of water flow in the river 2. For example, the supplementary data creation unit 16 calculates the time required for water to flow from the first water purification plant 31 to the second water purification plant 32, and calculates a coefficient for the water quality C measured at a time point corresponding to this amount of time back from the current time. By multiplying , the water quality C of the water taken in at the second water purification plant 32 is estimated. The coefficients are determined by performing a simulation or the like. The speed of water flowing in the river 2 is calculated by the complementary data creation unit 16 using the Manning formula, for example. The distance between the first water purification plant 31 and the second water purification plant 32 may be calculated by the complementary data creation unit 16 based on the position information of the first water purification plant 31 and the second water purification plant 32. The speed of the water flow in the river 2 may be acquired from the sensor if a sensor for measuring the flow speed is provided in the river 2.

The first water purification plant 31 and the second water purification plant 32 receive notifications of data that can be supplemented from the data management device 1, and request data supplementation if there is data that requires supplementation. In the present embodiment, when performing water purification using water quality C data that cannot be measured, the second water purification plant 32 requests complementation of water quality C data by transmitting a data complementation request.

As explained above, in the water treatment system 100 according to the first embodiment, the data management device 1 acquires water quality data from the first water purification plant 31 and the second water purification plant 32, and based on the acquired water quality data, Notify each water treatment plant of data that can be supplemented. Moreover, when the data management device 1 receives a data supplementation request from a water purification plant, it creates supplementary data for the requested water quality item and transmits it to the water purification plant. In the water treatment system 100, the second water purification plant 32 cannot measure the water quality C, but based on the water quality C measured at the first water purification plant 31, the data management device 1 determines the water quality at the second water purification plant 32. In order to estimate C, the second water purification plant 32 can perform water purification treatment using water quality C data. According to the water treatment system 100, water purification can be performed in the first water purification plant 31 and the second water purification plant 32 under appropriate conditions depending on the water quality while suppressing the number of sensors used in the entire system.

Note that in this embodiment, water quality items (water quality C) that cannot be measured at the downstream water purification plant (second water purification plant 32) are estimated based on the measurement results at the upstream water purification plant (first water purification plant 31). Although we have shown an example of this, it is also possible to estimate water quality items that cannot be measured at an upstream water purification plant based on the measurement results at a downstream water purification plant. In this case, the data management device 1 analyzes, for example, temporal fluctuations in measurement results at the downstream water purification plant, and estimates the quality of water taken in at the upstream water purification plant based on the analysis results. There is a correlation between temporal fluctuations in water quality at upstream water treatment plants and temporal fluctuations in water quality at downstream water treatment plants. Therefore, the data management device 1 is able to estimate the quality of water taken in by the upstream water treatment plant based on the water quality measured at the downstream water treatment plant and the temporal fluctuations in water quality at the downstream water treatment plant. .

In addition, in this embodiment, the water quality item (water quality C) that cannot be measured because the water quality sensor C is not installed at the downstream water purification plant (second water purification plant 32) is 31), but if water quality sensor B installed at the downstream water treatment plant (second water treatment plant 32) becomes unusable due to a failure, inspection, cleaning, etc. Furthermore, the water quality B measured at the upstream water purification plant (first water purification plant 31) can also be used as a means for estimating the water quality B at the downstream water purification plant (second water purification plant 32). Therefore, the failure resistance of the water treatment system 100 as a whole can be improved.

In addition, if water quality sensor B installed at the downstream water purification plant (second water purification plant 32) malfunctions and water quality B starts to show an incorrect value, By comparing it with the value of water quality B estimated based on the measurement results in step 31), it can also be used as a means to confirm that the value is incorrect. Therefore, a worker in charge of maintenance of the equipment can discover a malfunction without directly checking the water quality sensor of each water purification plant, and can reduce maintenance effort.

Similarly, if the water quality sensor installed at the upstream water treatment plant cannot be used due to failure, inspection, cleaning, etc., the water quality value measured by the water quality sensor at the downstream water treatment plant can be used to calculate the value. It can be used as a means of estimating and confirming that the value is incorrect.

Furthermore, in this embodiment, it is assumed that the data management device 1 holds position information of each water purification plant in advance, but each water purification plant may be equipped with a GPS (Global Positioning System) sensor or the like to acquire position information. If possible, the data management device 1 may acquire position information from each water purification plant (see FIG. 5). FIG. 5 is a diagram showing a modification of the water treatment system according to the first embodiment. As shown in FIG. 5, in the modified water treatment system 100a, the data management device 1a acquires position information and measurement data from the first water purification plant 31 and the second water purification plant 32. Note that the data management device 1a acquires position information from each water purification plant only once.

Embodiment 2.
Next, a water treatment system according to a second embodiment will be explained. Note that the configuration of the water treatment system according to the second embodiment is similar to the water treatment system 100 according to the first embodiment. The water treatment system according to the second embodiment differs from the first embodiment in the operation of the data management device. In this embodiment, descriptions of parts common to Embodiment 1 will be omitted, and parts different from Embodiment 1 will be described.

In the following description, for convenience, the water treatment system according to the second embodiment will be referred to as a water treatment system 100b. Further, the data management device that constitutes the water treatment system 100b will be referred to as a data management device 1b.

At water treatment plants, chemicals are used to disinfect and remove impurities when purifying water. The amount of chemicals used depends on the quality of the raw water, and if the water quality is poor, a large amount of chemicals will be required. Therefore, it is desirable that the quality of the water taken into the water treatment plant be as high as possible. Therefore, in this embodiment, the first water purification plant 31 on the upstream side issues a warning to the second water purification plant 32 on the downstream side when it detects deterioration in water quality. As a result, when the second water treatment plant 32 receives a warning of water quality deterioration, it can prevent the quality of the raw water to be treated from deteriorating by, for example, stopping the intake of water, and perform water purification efficiently. becomes possible.

FIG. 6 is a diagram showing a configuration example of the data management device 1b according to the second embodiment. The data management device 1b is obtained by adding a water quality abnormality detection section 21 and a warning section 22 to the data management device 1 according to the first embodiment.

The water quality abnormality detection unit 21 checks the latest water quality data acquired from the first water purification plant 31 among the water quality data held by the water quality data holding unit 19A, and determines that a specific water quality item to be monitored has an abnormal value. In other words, it is checked whether the value of the specific water quality item to be monitored is within the normal range. The water quality abnormality detection unit 21 determines that the water quality is abnormal if the value is not within the normal range. The warning unit 22 issues a warning of the water quality abnormality to the second water purification plant 32 when the water quality abnormality detection unit 21 detects the water quality abnormality.

FIG. 7 is a flowchart showing an example of the operation of the data management device 1b according to the second embodiment. The flowchart shown in FIG. 7 is obtained by adding steps S15 and S16 after step S14 of the flowchart shown in FIG. A description of steps S11 to S14 will be omitted.

After creating and transmitting the complementary data in step S14, the data management device 1b checks whether there is any water quality abnormality (step S15). Specifically, the water quality abnormality detection unit 21 analyzes the water quality data held in the water quality data holding unit 19A, and determines whether the value of a specific water quality item of the water taken in by the first water purification plant 31 is abnormal. confirm. For example, the water quality abnormality detection unit 21 checks whether the concentration of impurities such as sand and soil contained in the water is equal to or higher than a predetermined threshold value.

If there is no water quality abnormality (step S15: No), the data management device 1b returns to step S11 and continues the operation. On the other hand, if there is an abnormality in the water quality (step S15: Yes), the data management device 1b transmits a water quality abnormality warning (step S16). Specifically, the warning unit 22 transmits a warning to the second water purification plant 32 indicating that the quality of the water taken in by the first water purification plant 31 is abnormal. The second water purification plant 32 that has received this warning stops taking in water from the river 2, for example. This prevents the second water purification plant 32 from taking in turbid water, making it possible to improve the efficiency of water purification treatment.

When the water quality abnormality detection unit 21 of the data management device 1b detects an abnormality in the water quality of the water taken in by the first water purification plant 31, the water quality abnormality detection unit 21 estimates the time when the water quality of the water taken in by the second water purification plant 32 becomes abnormal. The water quality abnormality warning may include the time when the water quality becomes abnormal and send it. In this case, the second water purification plant 32 may increase the amount of water intake until the water quality becomes abnormal, and may take in the necessary amount of water in advance.

Note that, after detecting an abnormality in the water quality of the water taken in by the first water purification plant 31, the water quality abnormality detection unit 21 monitors whether the water quality has returned to normal. When the water quality abnormality detection unit 21 detects that the quality of the water taken in by the first water purification plant 31 has returned to normal, the warning unit 22 notifies the second water purification plant 32 of this fact. At this time, the water quality abnormality detection unit 21 estimates the time when the water quality of the water taken in by the second water purification plant 32 returns to normal, and the warning unit 22 notifies the second water purification plant 32 of the estimated time. The second water purification plant 32 may estimate the time when the water quality returns to normal.

As explained above, in the water treatment system 100b according to the second embodiment, the data management device 1b has the functions of the data management device 1 according to the first embodiment, as well as the functions of the water taken in at the first water purification plant 31. It has a function of monitoring changes in water quality and notifying the second water purification plant 32 if the water quality has deteriorated. In the water treatment system 100b, the second water purification plant 32 can know in advance that the water quality will deteriorate, and can perform operations in preparation for the deterioration of the water quality.

Note that in this embodiment, the data management device 1b detects an abnormality in the water quality of the water taken in by the first water purification plant 31, but when the first water purification plant 31 detects an abnormality in water quality, the data management device 1b It may be configured to notify.
