  As the facilities in the building, there are sanitary facilities for hygienically using water in the building, in addition to the electric facilities such as the air conditioner. In recent years, it has been proposed and realized that such sanitation facilities also store and reuse rainwater in consideration of water resource saving, cost reduction, environmental impact, etc. Yes.

  As described above, when reusing rainwater in a sanitary facility, it is preferable to use it as effectively as possible. However, at present, rainwater reuse plans are mostly performed by managers of sanitation facilities, for example, relying on experience, so rainwater is not necessarily reused appropriately in actual operations. Is not limited.

  According to the technique of Patent Document 1, an operation plan for appropriately operating an air conditioner in an air conditioner can be created and presented to an administrator, but the reuse of rainwater in the sanitary facility as described above is considered. It was n’t. From this point of view, it can be said that sanitary facilities, for example, appropriately create a rainwater reuse plan so that it can be proposed to the manager.

  Then, an object of this invention is to provide the sanitary equipment navigation apparatus which can manage the reuse of rainwater in a sanitary equipment appropriately.

  The present invention has been made to solve the above-described problems, and at least based on predicted precipitation predicted based on weather forecast data, rainwater is stored in accordance with the upper limit of the amount of water stored in the rainwater reuse tank. A determination unit that determines whether the rainwater stored in the rainwater storage tank is reusable or should be discharged to the sewer, and a display unit that displays information according to the determination result of the determination unit.

The rainfall upper limit value is set according to the operation, and the rainwater stored in the rainwater storage tank is determined based on a result of comparing the predicted precipitation amount predicted in the precipitation prediction time zone and the precipitation upper limit value. It is characterized by determining whether it can be reused or discharged into the sewer.

  In the sanitary equipment navigation device described above, when it is determined that the automatic operation should be performed by the operation, it is determined that the rainwater stored in the rainwater storage tank is reusable. The apparatus further includes an operation control unit that operates a sanitary facility including the rainwater storage tank so that rainwater stored in the rainwater storage tank is reused.

It is a figure which shows the example of a process sequence which the rainwater management apparatus in this embodiment performs for rainwater reuse determination. It is a figure which shows the example of a process sequence for the operation control which the rainwater management apparatus in this embodiment performs.

  FIG. 1 shows a configuration example of a sanitary equipment navigation system using the sanitary equipment navigation apparatus according to this embodiment. The sanitary facility navigation system shown in this figure includes a rainwater reuse tank 1, a rainwater storage tank 2, a filter 3, a miscellaneous water receiving tank 4, a middle water treatment facility 5, and a rainwater management apparatus 100. In this embodiment, as a sanitary facility, a case where rainwater is temporarily stored and used as miscellaneous water will be described as an example.

  The rainwater reuse tank 1 is a water tank that stores rainwater for reuse as, for example, miscellaneous water. When the rainwater stored in the rainwater reuse tank 1 is reused, the rainwater is pumped from the rainwater reuse tank 1 by the transfer pump 11 and supplied to the filter 3.

  The rainwater storage tank 2 is a water tank for limiting the outflow amount to the sewer of rainwater. In other words, when it rains, if each building or facility flows as it is into the sewer, the sewer tends to overflow. The rainwater storage tank 2 stores rainwater at the time of rainfall, and is used so that, for example, after rain stops, the rainwater stored by the amount of drainage per predetermined time is discharged to the sewer.

  Therefore, the rainwater storage tank 2 is generally kept empty when it is not raining. However, in the sanitary facility of this embodiment, for example, when it is predicted that it will not rain based on the weather forecast, the rainwater stored in the rainwater storage tank 2 is stored without being discharged. And the rainwater stored in the rainwater storage tank 2 is reused together with the rainwater stored in the rainwater reuse tank 1. Thereby, in the sanitary facility in the present embodiment, the amount of rainwater that can be reused increases, and for example, the amount of water used, the cost, and the like are suppressed. However, when it is predicted that it will rain, the rainwater stored in the rainwater storage tank 2 is discharged in advance so that the sewer does not overflow so that the rain can be stored.

  When draining rainwater stored in the rainwater storage tank 2 to the sewer, the drainage pump 21 causes the rainwater to be discharged from the rainwater storage tank 2. When the rainwater stored in the rainwater storage tank 2 is reused, the rainwater is pumped from the rainwater storage tank 2 by the transfer pump 22 and supplied to the filter 3. The rainwater pumped up by the transfer pump 22 is also used for outdoor discharge.

  The filter 3 filters rainwater pumped up for reuse from the rainwater reuse tank 1 or the rainwater storage tank 2 and supplies it to the miscellaneous water receiving tank 4.

The miscellaneous water receiving tank 4 is a water tank that stores water used as miscellaneous water. Rainwater from the rainwater reuse tank 1 and the rainwater storage tank 2 is filtered and supplied to the miscellaneous water receiving tank 4 by the filter 3. The miscellaneous water receiving tank 4 is replenished with clean water. The miscellaneous water receiving tank 4 is also supplied with medium water pumped up from the medium water treatment facility 5. The water stored in the miscellaneous water receiving tank 4 is pumped up by the water supply pump 41 and supplied to various facilities (not shown here) that use the miscellaneous water.
The middle water treatment facility 5 is a facility provided with a water tank for treating middle water. In the middle water treatment facility 5, water can be pumped up by the transfer pump 51 and supplied to the miscellaneous water receiving tank 4.

  The rainwater management device (sanitary equipment navigation device) 100 determines whether rainwater (stored rainwater) stored in the rainwater storage tank 2 should be reused based on weather forecast data. In other words, if the rainwater management apparatus 100 predicts that it will not rain, or if it is raining, it will be acceptable if it rains based on, for example, precipitation information for the last two days indicated by the weather forecast data. It is determined that the rainwater stored in the rainwater storage tank 2 can be reused. On the other hand, if the rainwater management apparatus 100 predicts that a certain amount of precipitation will occur based on the precipitation information in the weather forecast data, the rainwater storage device 2 discharges the rainwater stored in the rainwater storage tank 2 without reusing it. It is determined that it should be allowed.

  In addition, for the rainwater management apparatus 100, it is possible to set whether the operation of the sanitary equipment related to the reuse of rainwater is to be performed automatically or manually by the operation of the administrator. When it is determined that the stored rainwater in the rainwater storage tank 2 can be reused when the automatic operation is set, the rainwater management device 100 performs the automatic operation so that the stored rainwater is reused. . Specifically, the rainwater management apparatus 100 drives the transfer pump 22 to pump the rainwater stored in the rainwater storage tank 2 and supplies it to the filter 3. Further, the filter 3 is operated so as to filter the supplied rainwater.

  When the rainwater stored in the rainwater storage tank 2 is reusable, the rainwater reuse tank 1 and the rainwater storage tank 2 are prioritized to reuse the rainwater stored in the rainwater storage tank 2. For this reason, the rainwater management apparatus 100 stops the transfer pump 11 of the rainwater reuse tank 1 while driving the transfer pump 22 for pumping the rainwater stored in the rainwater storage tank 2. When rainwater needs to be reused when the rainwater stored in the rainwater storage tank 2 runs out, for example, the rainwater management apparatus 100 stops the transfer pump 22 of the rainwater storage tank 2 and uses the transfer pump 11 instead. To drive rainwater from the rainwater reuse tank 1 and supply it to the filter 3.

  Note that, as described above, the rainwater management apparatus 100 needs to acquire weather forecast data when determining whether or not the rainwater stored in the rainwater storage tank 2 is reusable. The rainwater management apparatus 100 acquires weather forecast data by accessing a server that provides weather forecast data via the network 6.

  FIG. 2 shows a configuration example of the rainwater management apparatus 100. The rainwater management apparatus 100 shown in this figure includes a determination unit 101, an evaluation unit 102, a display control unit 103, an operation control unit 104, a storage unit 105, an operation unit 106, a display unit 107, a network communication unit 108, and a data interface 109. .

The determination unit 101 determines whether rainwater stored in the rainwater storage tank 2 is reusable or should be discharged to the sewer based on the predicted precipitation predicted by the weather forecast data 151.
In this determination, for example, at least based on the predicted precipitation predicted based on the weather forecast data, the rainwater is stored in the rainwater storage tank in which rainwater is stored according to the upper limit of the storage amount in the rainwater reuse tank. Determine if rainwater is reusable or should be discharged into the sewer.

  Further, the determination unit 101 inputs and uses determination condition data 152 designated by an administrator's operation from the storage unit 105 as described later in making the above determination. The determination condition data 152 includes a precipitation prediction time zone and a precipitation upper limit value. The precipitation prediction time zone is a time zone that is a prediction target of the predicted precipitation amount used by the determination unit 101 for determination. The precipitation upper limit is the upper limit of precipitation in the precipitation forecast time zone.

  The predicted precipitation, which is the predicted value of precipitation in the precipitation prediction time zone, is compared with the upper limit of precipitation. If the predicted precipitation amount is smaller, the determination unit 101 determines that the rainwater stored in the rainwater storage tank 2 can be reused. On the other hand, the determination unit 101 determines that the rainwater stored in the rainwater storage tank 2 should be discharged to the sewer if the predicted precipitation amount is larger.

  The evaluation unit 102 obtains a result for each predetermined evaluation item in a past certain period (for example, one day) in which the rainwater stored in the rainwater storage tank 2 is reused. Moreover, estimation for every said evaluation item at the time of assuming that the stored rainwater of the rainwater storage tank 2 was not reused in the same past fixed period is performed.

  The display control unit 103 displays a user interface image (navigation screen) related to the determination by the determination unit 101. Through the operation on the navigation screen, the administrator can set the determination condition data and switch between automatic driving and manual driving, and the determination result by the determination unit 101 by looking at the navigation screen. Can be confirmed.

  The operation control unit 104 controls the operation related to the reuse of rainwater in the sanitary facility shown in FIG. Specifically, the operation control unit 104 controls the operation of the drainage pump 21 and the transfer pump 22 in the rainwater storage tank 2, the operation of the transfer pump 11 in the rainwater reuse tank 1, and the operation of the filter 3.

  In addition, the operation control unit 104 executes operation control corresponding to each of automatic operation and manual operation. That is, the rainwater management apparatus 100 sets either automatic operation or manual operation according to a predetermined operation performed on the operation unit 106. When the automatic operation is set and the determination unit 101 determines that the rainwater stored in the rainwater storage tank 2 is reusable, the operation control unit 104 stores the rainwater stored in the rainwater storage tank 2. Operation control is performed so that it can be reused. When manual operation is set, operation control is executed in accordance with the operation control content set by the operation performed by the administrator.

  The storage unit 105 stores various data necessary for rainwater management. Here, among the data stored in the storage unit 105, weather forecast data 151, determination condition data 152, automatic operation setting data 153, and performance data 154 are shown.

  The weather forecast data 151 is data including various types of information about the weather forecast acquired from the weather forecast server (not shown) via the network 6. The weather forecast data 151 includes information such as weather, precipitation, temperature, and humidity at regular intervals predicted for each forecast date.

  The determination condition data 152 is data indicating the contents of the determination conditions (precipitation prediction time zone and precipitation upper limit value). The precipitation prediction time zone and the precipitation upper limit as the determination conditions are set according to the operation of the operation unit 106 by the administrator. In addition, what kind of precipitation prediction time zone and the precipitation upper limit value as determination conditions are mentioned later.

  The automatic operation setting data 153 is data indicating whether the operation of the sanitary equipment is an automatic operation or a manual operation according to the operation of the administrator. The content of the automatic operation setting data 153 is set according to a predetermined operation performed on the operation unit 106 by the administrator.

  The result data 154 is data indicating various results based on the results of operating the sanitary equipment in the past. As an example, the performance data 154 includes the amount of stored water in the rainwater reuse tank 1, the amount of stored water in the rainwater storage tank 2, the amount of power used in the entire sanitary facility, and the like.

  The operation unit 106 collectively shows various operation devices such as a keyboard and a mouse. In response to an operation performed on the operation device, the operation unit 106 outputs an operation signal. In response to this operation signal, the predetermined functional unit shown in FIG. 2 performs an appropriate operation.

  The display unit 107 includes a predetermined display device such as a liquid crystal display, and displays an image according to the control of the display control unit 103. For example, the display unit 107 displays information according to the determination result of the determination unit 101 according to the instruction of the display control unit 103.

  The network communication unit 108 is a part that executes communication via the network 6. The network communication unit 108 can access the weather forecast server existing on the network 6 and download the weather forecast data 151 as described above.

  The data interface 109 executes communication with an external terminal according to a predetermined data interface standard. In the present embodiment, communication is performed with devices such as the transfer pumps 11, 21, and 22 in the sanitary facility and the filter 3 through the data interface 109. Thereby, operation control by the rainwater management apparatus 100 in a sanitary facility is attained. The rainwater management apparatus 100 can be realized by a computer device, for example.

  As described above, the rainwater management apparatus 100 can determine whether or not the rainwater stored in the rainwater storage tank 2 can be reused (reuse determination). In addition, the rainwater management apparatus 100 can display a navigation screen, which is a user interface image related to reuse determination, on the display unit 107 in accordance with a predetermined operation performed on the operation unit 106 by the administrator.

  FIG. 3 shows a display mode example of the precipitation forecast screen 200 displayed on the navigation screen. Here, for convenience, one precipitation forecast screen 200 is shown separately in FIG. 3 (a) and FIG. 3 (b). FIG. 3A shows the left part of the precipitation forecast screen 200, and FIG. 3B shows the right part following the precipitation forecast screen 200 of FIG.

  In the precipitation forecast screen 200 shown in this figure, precipitation amounts for “December 4, 2010”, “December 5, 2010”, and “December 6, 2010” are shown. Here, December 4, 2010 corresponds to the day when the precipitation forecast screen 200 is displayed. And the precipitation amount for every time slot | zone which divided 24 hours into 1 hour unit is shown for every day. That is, the precipitation forecast screen 200 shows the forecast of precipitation for the current day and the subsequent two days. The precipitation on the precipitation forecast screen 200 is based on the precipitation prediction information shown in the weather forecast data 151. By looking at this precipitation forecast screen 200, the administrator can grasp the contents of the forecast for the precipitation up to two days later.

  FIG. 4 shows a setting screen 300 displayed on the navigation screen. The setting screen 300 is a screen provided for an operation for setting the contents of the determination condition data 152. In response to this, on the setting screen 300, “precipitation amount prediction time zone” and “precipitation upper limit value” are shown as setting items. The administrator inputs a desired numerical value in each of the “set value” columns of “precipitation amount forecast time zone” and “precipitation upper limit value” by a predetermined operation on the operation unit 106.

  In the example of FIG. 4, “9 hours” is set for “Precipitation Prediction Time Zone”, and “10 mm or less” is set for “Precipitation Upper Limit”. The condition for determining that the rainwater in the rainwater storage tank 2 can be reused as the determination condition data 152 is predicted for 9 hours corresponding to “00:00 to 08:00”. It indicates that the precipitation is 10 mm or less. In correspondence with the example of FIG. 3, the predicted precipitation in 9 hours corresponding to the time zone from “00:00” to “08:00” on “December 5, 2010” is 7 mm. 10 mm or less. Therefore, the determination unit 101 in this case determines that the rainwater in the rainwater storage tank 2 can be reused.

  Further, in the setting screen 300 of FIG. 4, a column of “estimated precipitation amount in facility” is arranged. “Predicted rainfall in facility” indicates the amount of precipitation that the sanitation facility will capture in the time zone set as the “predicted rainfall time zone”. As an example, the “predicted precipitation amount in the facility” is obtained by multiplying the total area of the rainwater intake by the precipitation amount (mm) predicted in the “precipitation amount prediction time zone”. The display control unit 103 calculates the in-facility predicted precipitation amount every time the numerical value input in the “setting value” field of the setting screen 300 “precipitation amount prediction time zone” is changed. The predicted precipitation amount in the facility is displayed in the “Amount” column.

  On the navigation screen, evaluation screens 400A, 400B, 400C, and 400D shown in FIGS. 5A, 5B, 6A, and 6B are displayed.

  The evaluation screen 400A of FIG. 5A shows the actual amount of rainwater reused when the rainwater stored in the rainwater storage tank 2 is reused in the past certain period (for example, the previous day). Further, as a comparison, the amount of rainwater reuse estimated when it is assumed that the rainwater stored in the rainwater storage tank 2 is not reused in the same fixed period in the past is shown.

  In this evaluation screen 400A, the actual amount of rainwater reused in a past fixed period (for example, one day) is shown as a graph corresponding to “with control” on the left side of the figure. Further, the reuse amount predicted when it is assumed that rainwater is not reused in the same fixed period in the past is shown as a graph corresponding to “no control” on the right side of the figure. The graph corresponding to “no control” corresponds to, for example, the reuse amount of only the rainwater stored in the rainwater reuse tank 1.

  The evaluation screen 400B of FIG. 5B shows a track record of the amount of use of clean water in the entire building when the rainwater stored in the rainwater storage tank 2 is reused in a past fixed period, as a graph with “with control”. Further, as a comparison, the usage amount of clean water of rainwater estimated on the assumption that the rainwater stored in the rainwater storage tank 2 is not reused in the same fixed period in the past is shown as a graph of “no control”.

  The evaluation screen 400C in FIG. 6A shows a cost (for example, a water bill) required when the rainwater stored in the rainwater storage tank 2 is reused in a past fixed period by a graph “with control”. For comparison, a cost estimated when it is assumed that the rainwater stored in the rainwater storage tank 2 is not reused in the same fixed period in the past is shown as a “no control” graph.

The evaluation screen 400D of FIG. 6B shows the CO ² emission amount when the rainwater stored in the rainwater storage tank 2 is reused in a past fixed period by a graph “with control”. Further, as a comparison, the CO ² emission amount estimated when it is assumed that the rainwater stored in the rainwater storage tank 2 is not reused in the same fixed period in the past is shown as a graph of “no control”.

  The administrator can easily confirm the results of reusing the rainwater stored in the rainwater storage tank 2 by looking at the evaluation screens 400A, 400B, 400C, and 400D displayed as described above. Then, the manager can accurately determine whether or not to perform an operation for reusing the rainwater stored in the rainwater storage tank 2 from the results confirmed in this way.

  Note that, as the evaluation screens 400A, 400B, 400C, and 400D, for example, it is sufficient to display at least only past results corresponding to the “with control” graph. However, if the estimation result when it is assumed that the rainwater stored in the rainwater storage tank 2 is not reused is displayed as a comparison target, the administrator can effectively reuse the rainwater stored in the rainwater storage tank 2. Can be determined more accurately.

  The flowchart of FIG. 7 shows an example of a processing procedure corresponding to the rainwater reuse determination executed by the rainwater management apparatus 100. It should be noted that each process shown in this figure can be regarded as appropriately executed by any of the determination unit 101, the evaluation unit 102, and the display control unit 103 shown in FIG.

  First, the display control unit 103 waits for an operation on the operation unit 106 for instructing display of the navigation screen (step S101—NO). Then, in response to an operation for instructing display of the navigation screen, the display control unit 103 inputs the weather forecast data 151 from the storage unit 105 (step S102). In addition, the evaluation unit 102 inputs the record data 154 from the storage unit 105 (step S103).

  Next, the evaluation unit 102 uses the result data 154 input in step S103 to evaluate the amount of reused rainwater, the amount of water used in the entire building, the cost, the CO2 emission amount, and the like (step S104).

  Next, the display control unit 103 displays the navigation screen on the display unit 107 using the weather forecast data 151 input in step S102 and the evaluation result of the evaluation unit 102 in step S104 (step S105). As described above, the precipitation screen 200 of FIG. 3, the setting screen 300 of FIG. 4, and the evaluation screens 400A, 400B, 400C, and 400D of FIGS. 6 and 6 are displayed on the navigation screen. The display control unit 103 reflects the precipitation forecast information in the weather forecast data 151 on the precipitation forecast screen 200. Further, the display control unit 103 generates the evaluation screens 400A, 400B, 400C, and 400D based on the evaluation result of the evaluation unit 102 in step S104.

  The administrator performs an operation of inputting a desired numerical value in each column of “setting value” of “precipitation forecast time zone” and “precipitation upper limit value” on the setting screen 300 displayed on the navigation screen. In response to this operation, the determination unit 101 generates determination condition data 152 including a “precipitation amount prediction time zone” and a “precipitation upper limit value” that reflect the input numerical value, and stores the determination condition data 152 in the storage unit 105 ( Step S106).

  Next, the determination part 101 performs reuse determination about the rainwater stored in the rainwater storage tank 2 based on the weather forecast data 151 and the determination condition data 152 (step S107). That is, the determination unit 101 uses the weather forecast data 151 to predict the precipitation amount in the “precipitation amount prediction time zone” in the determination condition data 152. Next, the determination unit 101 determines that the predicted precipitation is reusable if it is equal to or less than the “precipitation upper limit value” in the determination condition data 152. On the other hand, the determination unit 101 determines not to reuse if the predicted precipitation is equal to or less than the “precipitation upper limit value”. The display control unit 103 displays the determination result in a predetermined manner on the navigation screen (step S108).

  The flowchart of FIG. 8 shows an example of a processing procedure executed by the rainwater management apparatus 100 for operation control. In the rainwater management apparatus 100, the operation control unit 104 refers to the automatic operation setting data 153 stored in the storage unit 105 and determines whether or not “automatic operation” is set (step S201).

  When it is determined that “automatic operation” is set (step S201—YES), the operation control unit 104 obtains a determination result that the rainwater stored in the rainwater storage tank 2 is reusable by the determination unit 101. It is determined whether or not (step S202).

  Here, when the determination result that the rainwater stored in the rainwater storage tank 2 is reusable is obtained (step S202—YES), the operation control unit 104 reuses the rainwater stored in the rainwater storage tank 2. Thus, the operation control for the sanitary equipment is executed (step S203). Thereby, the driving | operation for reusing the rainwater stored in the rainwater storage tank 2 is automatically performed.

  When it is determined that the rainwater stored in the rainwater storage tank 2 should not be reused (step S202—NO), the operation control unit 104 hygiene so as to reuse only the rainwater stored in the rainwater reuse tank 1. Operation control for the equipment is executed (step S204). Thereby, the driving | operation for reusing only the rainwater stored in the rainwater reuse tank 1 is automatically performed.

  When manual operation is set (step S201—NO), the operation control unit 104 executes operation control according to an operation for operation performed by the administrator on the operation unit 106 (step S201—NO). S205).

  In addition, the structure of the sanitary equipment in this embodiment is an example, and if it is a structure containing the rainwater reuse tank 1 and the rainwater storage tank 2, it will not specifically limit.
