For the usage amount (monthly amount) at the time of replacement, a value “10” obtained by subtracting the current meter reading value or the meter reading value after replacement “10” from the pre-replacement meter reading value “20” is used as the previous replacement (for example, the first replacement). A value “60” added to the replacement usage amount (monthly amount) “50” at the time is displayed.

  FIG. 16 is a diagram illustrating a usage amount display screen after replacement registration of a new instrument 20 is performed. Here, the meter reading value immediately after replacement is “1”. As shown in FIG. 16, the meter reading value before replacement and the usage amount at the time of replacement are not displayed on the usage amount display screen after the replacement registration is performed. In addition, the post-exchange meter reading value “1” acquired from the newly registered meter 20 is displayed as the current meter reading value or post-exchange meter reading value.

Next, a specific example is given of the flow of processing when the exchange of the meter 20 is performed once using FIG. 17 and the flow of processing when the replacement of the meter 20 is performed a plurality of times using FIG. explain.
FIG. 17 is a diagram illustrating a specific example of the flow of processing when the exchange of the meter 20 is performed once. In the example shown in FIG. 17, the previous closing date is 2:20 on October 31, the next closing date is 2:20 on November 30, and the daily metering date and time is 2:20. Here, it is assumed that the multiplier is 1, and the guideline value = the meter reading value. The horizontal axis in FIG. 17 represents time, and the vertical axis represents the pointer value. The resource usage calculation device 10 acquires the guideline value a1 as the meter reading value on the previous closing date (2:20 on October 31). Thereafter, the instrument 20 is replaced at 10:30 on November 20. The resource usage calculation device 10 acquires the guideline value a3 as the pre-replacement meter reading value by the meter-reading before the meter 20 is replaced. The resource usage calculation device 10 subtracts the guideline value a1 from the acquired guideline value a3, thereby calculating the usage amount A from the previous closing date to before the replacement of the meter 20. The resource usage calculation apparatus 10 registers the calculated usage A as a replacement usage in the replacement usage table in association with the number of replacements of the meter 20.

  Assuming that the pointer value of the meter 20 after replacement is b1, the resource usage calculation device 10 acquires the value of the pointer value b1 as the meter reading value after replacement. The resource usage calculation device 10 periodically acquires a meter reading value every day at 2:20, which is the date and time of meter reading. After that, when the meter 20 is not exchanged and the next closing date is reached (20:20 on November 30), the resource usage calculation device 10 will return to the previous closing date (2:20 on October 31). ) To the next closing date (2:20 on November 30). Specifically, the resource usage calculation device 10 first subtracts the guideline value b1 from the last acquired guideline value b3 at the present time (2:30 on November 30), thereby replacing the meter 20 Use amount B from (20:20 on November 20) to the next closing day (2:20 on November 30) is calculated. Then, the resource usage calculation device 10 adds the calculated usage A and usage B to the next closing date (November 31) from the previous closing date (02:20 on October 31). The total usage up to 2:20 on the 30th is calculated.

  FIG. 18 is a diagram showing a specific example of the flow of processing when the exchange of the instrument 20 is performed a plurality of times. In the example shown in FIG. 18, the previous closing date is 2:20 on October 31, the next closing date is 2:20 on November 30, and the daily metering date and time is 2:20. Here, it is assumed that the multiplier is 1, and the guideline value = the meter reading value. The horizontal axis in FIG. 18 represents time, and the vertical axis represents the pointer value. The resource usage calculation device 10 acquires the guideline value a1 as the meter reading value on the previous closing date (2:20 on October 31). Thereafter, the instrument 20 is replaced at 10:30 on November 10th. The resource usage calculation device 10 acquires the guideline value a3 as the pre-replacement meter reading value by the meter-reading before the meter 20 is replaced. The resource usage calculation device 10 subtracts the guideline value a1 from the acquired guideline value a3, thereby calculating the usage amount A from the previous closing date to before the replacement of the meter 20. The resource usage calculation apparatus 10 registers the calculated usage A as a replacement usage in the replacement usage table in association with the number of replacements of the meter 20. For example, the resource usage calculation apparatus 10 associates the number of times of replacement “1” with the replacement usage “A” and registers them in the replacement usage table.

  Assuming that the pointer value of the meter 20 after replacement is b1, the resource usage calculation device 10 acquires the value of the pointer value b1 as the meter reading value after replacement. The resource usage calculation device 10 periodically acquires a meter reading value every day at 2:20, which is the date and time of meter reading. Thereafter, it is assumed that the instrument 20 is exchanged for the second time at 8:15 on November 20. The resource usage calculation device 10 acquires the guideline value b3 as the pre-replacement meter reading value by the meter-reading before the meter 20 is replaced. The resource usage calculation device 10 calculates the usage B from the replacement of the first meter 20 to the replacement of the second meter 20 by subtracting the guide value b1 from the acquired guide value b3. The resource usage calculation device 10 registers the calculated usage B as an exchange usage in the exchange usage table in association with the number of exchanges of the meter 20. For example, the resource usage calculating device 10 associates the number of times of replacement “2” with the usage at the time of replacement “B” and registers them in the replacement usage table.

  If the pointer value of the meter 20 after replacement is c1, the resource usage calculation device 10 acquires the value of the pointer value c1 as the meter reading value after replacement. After that, when the meter 20 is not exchanged and the next closing date is reached (20:20 on November 30), the resource usage calculation device 10 will return to the previous closing date (2:20 on October 31). ) To the next closing date (2:20 on November 30). Specifically, first, the resource usage calculation device 10 subtracts the guideline value c1 from the guideline value c3 that was last acquired at the present time (2:20 on November 30), so that the second meter 20 The amount of use C is calculated after the exchange of (from 8:15 on November 20) until the next closing date (2:20 on November 30). Then, the resource usage calculation device 10 adds the calculated usage A, usage B, and usage C to the next from the previous closing date (2:20 on October 31). Calculate the total usage until the closing date (2:20 on November 30). In the third and subsequent processes, the same process as the second process is performed.

FIG. 19 is a flowchart showing a processing flow of the resource usage calculation device 10. The process of FIG. 19 is executed every time the instrument 20 is exchanged. That is, the process of FIG. 19 is executed at the timing when the meter reading execution instruction is transmitted to the meter 20.
The control unit 105 acquires the pre-exchange meter reading value from the meter 20 to be exchanged via the communication unit 101 (step S101). The control unit 105 uses the replacement usage amount corresponding to the supply facility to which the meter 20 that is the acquisition source of the pre-replacement meter reading value in the replacement usage amount table stored in the replacement usage amount table storage unit 1042 is attached. With reference to the table, it is determined whether or not it is the first replacement in the supply facility to which the meter 20 that is the acquisition source of the pre-exchange meter reading value is attached from the previous closing date to the next closing date (step S102). ). Specifically, the control unit 105 determines that the replacement is the first when the value is not registered in the replacement usage amount table. On the other hand, the control unit 105 determines that the replacement is not the first time when the value is registered in the replacement usage amount table. Hereinafter, the supply facility to which the meter 20 that is the acquisition source of the pre-replacement meter reading value is attached is referred to as a replacement target supply facility.

  When it is determined that this is the first replacement (step S102-YES), the calculation unit 106 reads the current meter reading value of the meter 20 corresponding to the replacement target supply facility stored in the meter information storage unit 1041 and the acquired replacement. The usage amount at the time of replacement is calculated from the previous meter reading value (step S103). Specifically, the calculation unit 106 calculates the replacement usage amount by subtracting the current month meter reading value from the pre-exchange meter reading value. On the other hand, when it is determined that the replacement is not the first time (step S102-NO), the calculation unit 106 acquires the post-replacement meter reading value of the meter 20 corresponding to the replacement target supply facility stored in the meter information storage unit 1041. The used amount at the time of replacement is calculated from the meter reading value before replacement (step S104). Specifically, the calculation unit 106 calculates the replacement usage amount by subtracting the post-exchange meter reading value from the pre-exchange meter reading value.

  The calculating unit 106 stores the calculated replacement usage amount in the replacement usage table storage unit 1042 (step S105). Specifically, when it is determined that the replacement is the first time in the process of step S102, the calculation unit 106 associates with the replacement count “1” in the replacement usage amount table corresponding to the replacement target supply facility. The calculated usage amount at the time of replacement is stored. When it is determined that the replacement is not the first time in the process of step S102, the calculation unit 106 calculates the replacement in association with the corresponding number of replacements in the replacement usage amount table corresponding to the replacement target supply facility. Memorize hourly usage.

  The calculation unit 106 includes a daily meter reading value acquired from the meter 20 corresponding to the replacement target supply facility stored in the meter information storage unit 1041, a current meter reading value or a post-replacement meter reading value, a replacement usage amount table, Based on the above, a replacement usage amount (daily amount) and a replacement usage amount (monthly amount) are calculated (step S106). The calculating unit 106 stores the calculated replacement usage amount (daily amount) and replacement usage amount (monthly amount) in the meter information storage unit 1041 in association with the meter 20 corresponding to the replacement target supply facility. Thereafter, the control unit 105 reads the pre-replacement meter reading value acquired in the process of step S101, the replacement use amount stored in the replacement use amount table, and the replacement use amount calculated in the process of step S106 ( The display of the usage amount display screen is controlled based on the daily amount) and the usage amount at the time of replacement (monthly amount) (step S107). Specifically, when it is determined that the replacement is the first time in the process of step S102, for example, the control unit 105 displays a usage amount display screen as shown in FIG. If it is determined in step S102 that the replacement is not the first time, for example, the control unit 105 displays a usage amount display screen as shown in FIG.

  Thereafter, the control unit 105 determines whether or not replacement registration of the meter 20 has been performed (step S108). Specifically, the identification information of the newly exchanged instrument 20, the information on the supply equipment to which the newly exchanged instrument 20 is attached, and the post-exchange meter reading value are input via the input unit 102. In this case, the control unit 105 determines that the replacement registration of the meter 20 has been performed. On the other hand, in other cases, the control unit 105 determines that the replacement registration of the meter 20 has not been performed. When the exchange registration of the meter 20 is not performed (step S108—NO), the resource usage calculation device 10 repeatedly executes the process of step S108. On the other hand, when the exchange registration of the meter 20 is performed (step S108—YES), the control unit 105 controls the display of the usage amount display screen based on the input information and the like (step S109). For example, the control unit 105 displays a usage amount display screen as shown in FIG. 7, FIG. 10, FIG.

According to the resource usage calculation device 10 configured as described above, even if the meter attached to the supply facility is exchanged a plurality of times between the previous closing date and the next closing date. It becomes possible to calculate the total usage from the previous closing date to the next closing date. Hereinafter, this effect will be specifically described.
The resource usage calculation device 10 stores the usage amount at the time of replacement for each supply facility in association with the number of replacements of the meter 20 between the previous closing date and the next closing date. That is, the resource usage calculation device 10 stores the usage amount at the time of replacement when the meter 20 is exchanged five times with the same supply equipment between the previous closing date and the next closing date. To do. Then, the resource usage calculation device 10 uses the stored usage amount at the time of replacement and the usage amount from the last replacement to the closing date on the closing date, from the previous closing date to the next closing date. The total usage amount is calculated for each supply facility. For this reason, the resource usage calculation device 10 does not change from the previous closing date to the next closing date, even if the meter attached to the supply facility is replaced several times. It is possible to calculate the total amount of use up to the closing date.

In addition, the resource usage calculation device 10 corrects the stored usage at the time of replacement according to the user's operation. Therefore, it can be corrected immediately when the meter reading value is incorrect.
In addition, when the meter 20 is replaced by the next closing date, the resource usage calculation device 10 not only displays the usage amount at the time of replacement (monthly amount) but also the meter reading value before replacement and the replacement on the usage amount display screen. The hourly usage is also displayed. This makes it easy to check at which timing the wrong usage amount (monthly amount) was exchanged. As a result, the time required for correction can be reduced.
In addition, the resource usage calculation device 10 displays the exchange usage registered in the exchange usage table in association with the number of exchanges in accordance with a user instruction. Therefore, the user can grasp how many times the instrument 20 has been exchanged between the previous closing date and the next closing date by looking at the displayed information.

Hereinafter, modified examples of the resource usage calculation device 10 will be described.
The control unit 105 may be configured to delete the replacement usage amount registered in the replacement usage amount table at a predetermined timing. The predetermined timing may be, for example, a timing after the total usage amount that is the total usage amount from the previous closing date to the next closing date is calculated, or from the user after the total usage amount is calculated. The timing at which the deletion instruction is input may be at other timings.
In the present embodiment, a configuration in which the meter reading value is directly transmitted from the meter 20 to the resource usage calculation device 10 is shown. However, a device that transmits data between the meter 20 and the resource usage calculation device 10 (for example, A wireless transmission board or the like may be provided.

  The meter 20 may include a meter that does not have a communication function. When the meter 20 is a meter that does not have a communication function, a worker reads the guideline value of the meter 20, and the user operating the resource usage amount calculation device 10 calculates the resource usage amount by reading the guideline value read by the worker. It is necessary to input to the device 10. In this case, the user may input an incorrect guideline value. In this case, an error occurs in the total usage value. Hereinafter, the usage amount correction method in this case will be described.

  FIG. 20 is a diagram for explaining a correction method in the case where the pointer value is input with a value smaller than the actual value. The horizontal axis in FIG. 20 represents time, and the vertical axis represents the pointer value. The operator reads “50” from the meter 20 as the guideline value A on the previous closing date. Thereafter, the user inputs the guideline value “50” read by the worker to the resource usage calculation device 10. Thereafter, the instrument 20 is replaced. At this time, the worker reads the pointer value B1 (for example, 170) as the pre-replacement meter reading value by the meter-reading before the meter 20 is replaced. Here, when the user inputs the guideline value B1 read by the worker to the resource usage amount calculation device 10, the guideline value B2 (for example, 120) smaller than the guideline value B1 by a (for example, 50) is erroneously input. Suppose that The resource usage calculation device 10 multiplies the value obtained by subtracting the guideline value A from the input guideline value B2 by a multiplier (for example, 1), thereby using the usage amount X from the previous closing date to before the replacement of the meter 20. (For example, 70) is calculated.

  If the pointer value of the meter 20 after replacement is C1 (for example, 0), the resource usage calculation device 10 acquires the value of the pointer value C1 as the pointer value after replacement by user input. Thereafter, when the user notices that the pre-replacement meter reading value has been erroneously input by a after a predetermined date and time, the user corrects the pointer value. Specifically, the user first obtains the current pointer value C2 (for example, 40) of the meter 20 from the worker. Next, the user inputs a value C3 (for example, 90) obtained by adding a to the obtained guideline value C2 to the resource usage calculation device 10 as a pre-replacement meter reading value. Further, the user inputs the actual guideline value C2 of the meter 20 as the post-replacement guideline value. Then, the worker reads the guide value C4 (for example, 107) from the meter 20 as the guide value on the next closing date. Thereafter, the user inputs the guideline value C4 read by the worker to the resource usage calculation device 10. Thereafter, the resource usage calculation device 10 calculates the combined usage on the closing date based on the input value. For example, the resource usage calculation apparatus 10 uses X (B2-A), which is the usage amount in the T-th process, Y (C3-C1), (C4-C2), which is the usage amount in the T + 1-th process. The combined usage is calculated by adding By performing such processing, even if the guideline value is smaller than the actual value, the usage amount can be corrected and the total usage amount can be calculated.

  FIG. 21 is a diagram showing a specific example of a database in which data when the processing shown in FIG. 20 is performed is registered. The database shown in FIG. 21 may be stored in the replacement usage table storage unit 1042 as a replacement usage table. The database has a plurality of records. The record has each value of processing execution date, meter reading result reflection date, meter reading value before replacement, guide value after replacement, multiplier after replacement, multiplier before replacement, and usage amount at replacement. The value of the process execution date represents the date and time when the process for the meter 20 was performed. Here, the processing includes replacement of the instrument 20 itself as described above and correction of the pointer value. The value of the meter reading result reflection date of a certain record represents the date reflecting the result of the processing executed on a certain processing execution date. The pre-replacement meter reading value of a record represents the pre-replacement meter reading value input from the user by the process executed on a certain process execution date. The value of the guideline value after replacement of a certain record represents the guideline value of the meter 20 input from the user by the process executed on a certain process execution date. The value of the post-exchange multiplier of a certain record represents the multiplier input from the user by the process executed on a certain process execution date. The value of the pre-exchange multiplier of a certain record represents the multiplier input by the user in the process immediately before the process executed on a certain process execution date. The value of the usage amount at the time of replacement of a certain record represents the usage amount calculated based on the meter reading value acquired from the meter 20.

  In the example shown in FIG. 21, two records are registered in the database. In FIG. 21, the data registered in the T-th process in FIG. 20 is registered in the record registered in the top row of the database, and the T + 1-th record in FIG. 20 is registered in the record registered in the second row in the database. Data for processing is registered. Using the record registered at the top of the database as an example, each value (120, 0, 1, 1 and 70) of the meter reading value before replacement, the guide value after replacement, the multiplier after replacement, the multiplier before replacement, and the usage amount at the time of replacement explain. The pre-exchange meter reading value “120” is a pointer value input by the user as the pre-exchange meter reading value. The correct guideline value is B1 (170), but “120” is registered because the user erroneously inputs B2 (120). The post-exchange guideline value “0” is the guideline value C1 input by the user. The post-replacement multiplier “1” is a multiplier of the meter 20 after the replacement input by the user. The pre-exchange multiplier “1” is a multiplier of the meter 20 input by the user in the T−1th process. The replacement use amount “70” is a value obtained by subtracting the indicator value A “50” of the meter 20 on the previous closing date from the pre-replacement meter reading value “120”.

  Also, taking the record registered in the second row of the database as an example, each value of the meter reading value before replacement, the guide value after replacement, the multiplier after replacement, the multiplier before replacement, and the usage amount during replacement (90, 50, 1, 1, and 90). The pre-replacement meter reading value “90” is a pointer value input by the user as a pre-replacement meter reading value. The correct guideline value is C2 (40), but “90”, in which the value of a is added to correct the value a (50) erroneously input by the user in the T-th process, is registered. The post-exchange guideline value “50” is the guideline value C2 input by the user. Because it is for correction and the actual meter 20 is not replaced, the value of C2 is registered as the pointer value after replacement. The post-replacement multiplier “1” is a multiplier of the meter 20 after the replacement input by the user. The pre-exchange multiplier “1” is a multiplier of the meter 20 input by the user in the T-th process. The replacement use amount “90” is a value obtained by subtracting the post-replacement indicator value “0” in the T-th process from the pre-replacement meter reading value “90”.

  FIG. 22 is a diagram for explaining a correction method when the pointer value is input with a value larger than the actual value. The horizontal axis in FIG. 22 represents time, and the vertical axis represents the pointer value. The operator reads “50” from the meter 20 as the guideline value A on the previous closing date. Thereafter, the user inputs the guideline value “50” read by the worker to the resource usage calculation device 10. Thereafter, the instrument 20 is replaced. At this time, the worker reads the pointer value B3 (for example, 120) as the pre-replacement meter reading value by the meter-reading before the meter 20 is replaced. Here, when the user inputs the guideline value B3 read by the worker to the resource usage calculation device 10, the user erroneously inputs the guideline value B4 (for example, 170) larger by a (for example, 50) than the guideline value B3. Suppose that The resource usage calculation device 10 multiplies the value obtained by subtracting the guideline value A from the input guideline value B4 by a multiplier (for example, 1), thereby using the usage amount X1 from the previous closing date to before the replacement of the meter 20. (For example, 120) is calculated.

  If the pointer value of the meter 20 after replacement is C5 (for example, 0), the resource usage calculation device 10 acquires the value of the pointer value C5 as the pointer value after replacement by user input. Thereafter, when the user notices that the pre-replacement meter reading value has been mistakenly input by a after a predetermined date and time, the user corrects the pointer value. Specifically, the user first obtains the pointer value C6 (for example, 60) of the meter 20 at the present time from the worker. Next, the user inputs a value C7 (for example, 10) obtained by subtracting a from the acquired guideline value C6 to the resource usage calculation device 10 as a pre-replacement meter reading value. Further, the user inputs the actual guideline value C6 of the meter 20 as the post-replacement guideline value. Then, the worker reads a guide value C8 (for example, 107) from the meter 20 as a guide value on the next closing date. Thereafter, the user inputs the guideline value C8 read by the worker to the resource usage calculation device 10. Thereafter, the resource usage calculation device 10 calculates the combined usage on the closing date based on the input value. For example, the resource usage calculation apparatus 10 uses X1 (B4-A), which is the usage amount in the T-th process, Y1 (C7-C5), (C8-C6), which is the usage amount in the T + 1-th processing. The combined usage is calculated by adding By performing such processing, even when the guideline value is input with a value larger than the actual value, the usage amount can be corrected and the total usage amount can be calculated.

  FIG. 23 is a diagram illustrating a specific example of a database in which data is registered when the processing illustrated in FIG. 22 is performed. The database shown in FIG. 23 is the same as the database shown in FIG. In the example shown in FIG. 23, two records are registered in the database. In FIG. 23, the data registered in the T-th process in FIG. 22 is registered in the record registered in the top row of the database, and the T + 1-th record in FIG. 22 is registered in the record registered in the second row in the database. Data for processing is registered. Using the record registered at the top of the database as an example, each value of the pre-replacement meter reading value, post-replacement guideline value, post-replacement multiplier, pre-replacement multiplier and replacement usage (170, 0, 1, 1 and 120) explain. The pre-exchange meter reading value “170” is a pointer value input by the user as a pre-exchange meter reading value. The correct guideline value is B3 (120), but “170” is registered because the user erroneously inputs B4 (170). The post-exchange guideline value “0” is the guideline value C5 input by the user. The post-replacement multiplier “1” is a multiplier of the meter 20 after the replacement input by the user. The pre-exchange multiplier “1” is a multiplier of the meter 20 input by the user in the T−1th process. The replacement usage amount “120” is a value obtained by subtracting the indicator value A “50” of the meter 20 on the previous closing date from the pre-replacement meter reading value “170”.

  Further, taking the record registered in the second row of the database as an example, each value of the pre-replacement meter reading value, the post-replacement guideline value, the post-replacement multiplier, the pre-replacement multiplier, and the usage amount at the time of replacement (10, 60, 1, 1, and 10) will be described. The pre-exchange meter reading value “10” is a pointer value input by the user as a pre-exchange meter reading value. The correct guideline value is C6 (60), but “10” obtained by subtracting the value of “a” is registered in order to correct the value a (50) erroneously input by the user in the T-th process. The post-exchange guideline value “60” is the guideline value C6 input by the user. Since this is for correction and the actual instrument 20 is not replaced, the value of C6 is registered as the pointer value after replacement. The post-replacement multiplier “1” is a multiplier of the meter 20 after the replacement input by the user. The pre-exchange multiplier “1” is a multiplier of the meter 20 input by the user in the T-th process. The replacement use amount “10” is a value obtained by subtracting the post-replacement indicator value “0” in the T-th process from the pre-replacement meter reading value “10”.

  According to at least one embodiment described above, every time an instrument 20 attached to a supply facility that supplies resources such as electricity, water, gas, etc., that measures the amount of resources consumed by the supply facility is replaced. In addition, a replacement use amount table storage unit 1042 for storing the replacement use amount obtained from the meter 20 in association with the number of replacements between the previous closing date and the next closing date, and a replacement use amount table storage unit By having a calculation unit 106 that calculates a total usage amount from the previous closing date to the next closing date in the same supply facility using a plurality of replacement usage amounts of the same supply facility stored in 1042 Even if the meter attached to the supply equipment is replaced several times between the previous closing date and the next closing date, the total usage amount from the previous closing date to the next closing date is To calculate It can be.
