Description

  In the present invention, when an integrated measurement value integrated and measured by a plurality of measurement meters installed in a building and an integrated measurement value displayed on a central monitoring device based on a signal transmitted from each measurement meter are read. The present invention relates to an inspection schedule creation device for creating an inspection schedule.

In a building such as a building, a plurality of metering meters (billing meters) for integrating and measuring the usage of various utilities (electric power, gas, water, etc.) are installed. These weighing meters are connected to a central monitoring device via a controller, and transmit a pulse signal indicating this value every time the integrated weighing value increases by a predetermined amount. In the central monitoring device, the integrated measurement value at each measurement meter indicated by the received pulse signal is displayed and managed as one of the monitoring points. On the other hand, the claimant who charges each tenant in the building for the usage fee of various utilities calculates the usage fee based on the integrated measurement value displayed on the measurement meter. That is, a device used when managing the integrated measurement value is different from a device used when calculating the usage fee from the integrated measurement value. For this reason, the integrated measurement values indicated by both devices need to match.
However, the integrated measurement value displayed on the weighing meter and the central monitoring device may be affected by a power failure test when the building is built, a signal line breakage between the weighing meter and the central monitoring device, or a failure of the measuring meter. There may be an error in the managed total weight value.

Therefore, a check is periodically performed to check whether the integrated measured value displayed on the weighing meter matches the integrated measured value managed by the central monitoring device.
This inspection is divided into an operator who reads the integrated weighing value displayed on the weighing meter and an operator who reads the integrated weighing value managed by the central monitoring device. The consistency of the integrated measurement value is confirmed. In addition, it is necessary to perform a reading operation several times for one weighing meter in one inspection. If there is an error between the integrated measured value displayed on the weighing meter and the integrated measured value managed by the central monitoring device, the error is corrected. That is, for example, in the case of an error due to a power failure test, the integrated measurement value is corrected by the central monitoring device, and in the case of an error due to a broken signal line or a failure of the metering meter, the error is replaced and repaired. Correct the integrated measurement value on the monitoring device.

Japanese Patent Laid-Open No. 2000-310652

As described above, in order to check whether there is an error between the integrated measured value displayed on the weighing meter and the integrated measured value managed by the central monitoring device, both integrated measured values are read several times. Is going. At this time, in order to confirm that there is no error between the increase in the integrated measurement value displayed on the weighing meter and the increase in the integrated measurement value managed by the central monitoring device, It is necessary to perform the next reading while the integrated measurement value has increased to some extent.
However, since the way the meter proceeds depends on conditions such as the type, installation location, and usage of the meter, it is not known at what timing the integrated meter value should be read. Therefore, although it went to the installation place of the metering meter, it still cannot be inspected, and it may be necessary to go back in time and inspect again, resulting in poor inspection efficiency.

  In Patent Document 1, a first data collection device that collects values managed by the central monitoring device every predetermined time, and a value that is displayed by a worker and displayed on a weighing meter are recorded. An apparatus for comparing values collected and stored by first and second data collecting apparatuses is disclosed. With the device disclosed in Patent Document 1, it is possible for one worker to read the value displayed on the weighing meter and the value managed by the central monitoring device. However, it is impossible to know in advance which metering meter should be inspected at which timing, and it is impossible to improve the inspection efficiency.

  The present invention has been made to solve the above-described problems, and predicts the timing for reading the integrated measurement value displayed on each measurement meter and the integrated measurement value managed by the central monitoring device. It is an object of the present invention to provide an inspection schedule creation device that can improve the inspection efficiency.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
As shown in FIG. 1, the weighing meter management system includes a weighing meter 1, a central monitoring device 2, and an inspection schedule creation device 3.
A plurality of metering meters 1 are installed in a building such as a predetermined building, and are used to integrate and measure the usage of corresponding utilities (electricity, gas, water, etc.). In addition, the integrated measurement value is displayed on the display unit of the measurement meter 1. The meter 1 transmits a pulse signal indicating the integrated measurement value to the central monitoring device 2 every time the integrated measurement value increases by a predetermined amount.
The central monitoring device 2 acquires and manages the integrated measurement value in each meter 1 by receiving a pulse signal from each meter 1. The meter 1 may transmit a pulse signal to a controller (not shown), and the controller may convert the pulse signal into a signal indicating an integrated measurement value and transmit the signal to the central monitoring device 2.

  The inspection schedule creation device 3 reads the integrated measured value displayed on each weighing meter 1 and the corresponding integrated measured value managed (displayed) by the central monitoring device 2, and determines whether the values match. When performing the check to be confirmed, the check schedule is created to support the timing at which each metering meter 1 can read, and is configured from a PC. As shown in FIG. 1, the inspection schedule creation device 3 includes a meter meter information storage unit 31, an integrated measurement value storage unit 32, an increase amount calculation unit 33, an inspection condition input unit 34, an expected inspection time calculation unit 35, and an inspection support. The information display unit 36 is configured.

  The meter meter information storage unit 31 stores information related to each meter 1 (type, installed management area, application, name, etc.) in association with the identification information of the meter 1. In addition, as a classification of the metering meter 1, an electric power meter, a gas meter, a water meter, etc. are mentioned.

  The integrated measurement value storage unit 32 receives a signal indicating a past integrated measurement value for each meter 1 managed by the central monitoring device 2 by connecting to the central monitoring device 2 via a LAN before performing the inspection. These are stored in association with the identification information of the weighing meter 1. At this time, the integrated measurement value storage unit 32 receives a signal indicating a past integrated measurement value for a predetermined period (for example, one day or one week).

  The increase amount calculation unit 33 calculates an increase amount of the integrated measurement value for each predetermined period for each meter 1 based on the integrated measurement value stored in the integrated measurement value storage unit 32. At this time, when the integrated measurement values for a plurality of days are stored in the integrated measurement value storage unit 32, the increments of the integrated measurement values for each day for each predetermined period are averaged for each meter 1. It may be. Further, only the increase amount on the corresponding day in the past may be calculated in consideration of the day of the inspection day.

  The inspection condition input unit 34 receives conditions for performing inspection from an operator. Here, the inspection conditions include the type of the meter 1 to be inspected, the management area to be inspected (a predetermined floor in the managed building, the entire building, etc.), the time at which the inspection is started, and the like.

The expected inspection time calculation unit 35 determines a predetermined inspection start time and a predetermined inspection time for each meter 1 based on the meter meter information stored in the meter meter information storage unit 31 and the increment calculated by the increment calculator 33. A time at which the integrated value of the increase amount becomes equal to or greater than a predetermined threshold is used as a starting point for the increase amount, and a plurality of times at which the integrated value of the increase amount is equal to or greater than the predetermined threshold are calculated as expected inspection times. Note that the threshold value used in this case is not less than the amount of increase in the integrated measurement value necessary from the previous inspection to the next inspection in the predetermined type of meter 1.
Further, when the inspection condition input unit 34 receives the type of the metering meter 1 or the management area where the inspection is to be performed, the expected inspection time calculation unit 35 detects the metering meter 1 that matches this condition, and performs this measurement. The expected inspection time is calculated only for the meter 1. Further, when the inspection start time is received by the inspection condition input unit 34, the expected inspection time is calculated using this time as the inspection start time.

  The inspection support information display unit 36 uses each metering expected time calculated for each metering meter 1 calculated by the expected metering time calculation unit 35 based on the metering meter information stored in the metering meter information storage unit 31 as a metering meter name. The associated inspection schedule is displayed. The expected inspection time may be displayed for a predetermined number of times (for example, three times) on one weighing meter 1.

Next, the operation of the inspection schedule creation device 3 configured as described above will be described.
FIG. 2 is a flowchart showing the operation of the inspection schedule creation device 3 according to Embodiment 1 of the present invention. In FIGS. 3-6, the case where an inspection schedule is produced with respect to three electric power meter AC is shown. Here, it is assumed that the power meter A is installed on the first floor (1F), the power meter B is installed on the second floor (2F), and the power meter C is installed on the third floor (3F). In the metering meter information storage unit 31, information (type, installed management area, usage, name, etc.) relating to each of the power meters A to C is used as the metering meter information in advance as identification information of the power meters A to C. It is stored in association.

  In the operation of the inspection schedule creation device 3, as shown in FIG. 2, first, the inspection schedule creation device 3 is connected to the central monitoring device 2 via the LAN before the inspection is performed, and the integrated measurement value storage unit 32 performs the central monitoring. A signal indicating the past integrated measurement value for each meter 1 managed by the device 2 is received and stored in association with the identification information of the meter 1 (step ST1). FIG. 3 shows a case where the past integrated measurement values at the power meters A to C for each hour on one day (8:00 to 8:00) before the inspection date are received.

  Next, the increase amount calculation unit 33 calculates the increase amount of the integrated measurement value for each predetermined period for each meter 1 based on the integrated measurement value stored in the integrated measurement value storage unit 32 (step ST2). . FIG. 4 shows a case where the amount of increase in the integrated metric value for each hour is calculated using the integrated metric value in the power meters A to C in FIG. 3. As a result, the power meter A can grasp that the integrated measurement value increases at a constant rate, and the power meters B and C have a time zone in which no power is used or a time zone in which the power meter is used frequently. You can see that it exists.

  Next, the inspection condition input unit 34 receives a condition for performing an inspection from an operator (step ST3). For example, conditions such as when only a predetermined type of meter 1 is inspected, when only the meter 1 in a predetermined floor is inspected, or when inspection is started from a predetermined time are specified. These conditions may be specified in combination, or conditions may not be specified. In the following, the case where no condition is specified is shown.

  Next, the expected inspection time calculation unit 35 starts predetermined inspection for each meter 1 based on the meter meter information stored in the meter meter information storage unit 31 and the increment calculated by the increment calculator 33. A time at which the integrated value of the time and the increase amount is equal to or greater than a predetermined threshold is set as the integration start point of the increase amount, and a plurality of times at which the integrated value of the increase is equal to or greater than the predetermined threshold are calculated as expected inspection times (step ST4). . For example, in FIG. 4, when the threshold value is 3 kW and the inspection start time is 8:00, the power meter A first integrates the increase amount with the inspection start time (8:00) as the integration start point. Therefore, this 11:00 is assumed to be the first expected inspection time. Next, if the increase amount is integrated with 11:00 as the integration start point, it becomes equal to or greater than the threshold at 14:00, so this 14:00 is set as the second expected inspection time. On the other hand, in the electric power meter B, the integrated measurement value does not change for a while from the inspection start time (8 o'clock), and thereafter, the integrated value of the increase amount exceeds the threshold at 15:00. Estimated inspection time. In this way, for each of the power meters A to C, it is possible to predict a time when the integrated measurement value increases by a predetermined amount or more and reading is possible. Note that the threshold value may be the amount of increase in the integrated measurement value required from the previous inspection to the next inspection itself. However, the threshold value is a value that has a certain amount added to allow for a margin. The reliability of the expected time can be further increased.

  Next, the inspection support information display unit 36 displays each estimated expected time for each weighing meter 1 calculated by the estimated inspection time calculation unit 35 based on the measured meter information stored in the measured meter information storage unit 31. The inspection schedule associated with the name is displayed (step ST5). For example, as shown in FIG. 5, each inspection expected time for each power meter A to C is displayed in a list. The list in FIG. 5 is based on the list of increments of the integrated measurement values shown in FIG. In FIG. 5, the inspection start time is set to 8:00, and the set number of inspection expected times for the power meters A to C is set to three.

  Further, the inspection support information display unit 36 may display an inspection schedule as shown in FIG. In FIG. 6, the electric power meters A to C corresponding to the expected inspection time are shown in a cyclic order every hour. Here, the inspection support information display unit 36 collectively displays the measurement meters 1 and the same type of measurement meters 1 that exist in the same management area among the measurement meters 1 corresponding to the expected times of inspection. That is, for example, when the power meter C installed on the first floor and the power meters D to G installed on the third floor are at the expected inspection time at a certain time, the power meters D to G on the third floor are Make sure that all inspections are performed together. Thereby, inspection can be performed without reciprocating each floor many times, and inspection efficiency can be further improved.

  Note that if the inspection cannot be performed at the expected inspection time indicated in the inspection schedule by the inspection support information display unit 36, a deviation occurs in the subsequent expected inspection time. For example, in FIG. 5, the power meter A is the first expected check time at 11:00, but if for some reason the worker cannot check at 11:00 and checks at 12:00, The inspection schedule is shifted by one hour, and the inspection cannot be performed at the next expected inspection time (14:00, 17:00). Therefore, in such a case, the current time is designated as the inspection start time via the inspection condition input unit 34, and the expected inspection time is calculated and displayed again. That is, in the case of the above example, the inspection start time is specified at 12:00, the inspection expected time calculation / display process is performed again, and new expected inspection times (15:00, 18:00) are acquired.

  As described above, according to the first embodiment, the past integrated measurement value for each weighing meter 1 is collected and stored from the central monitoring device 2, and each inspection expectation for each weighing meter 1 is estimated based on this value. Since the time is calculated and displayed, it is possible to predict the timing of reading the integrated measured value displayed on each weighing meter 1 and the integrated measured value managed by the central monitoring device 2. Can increase the inspection efficiency.

In the first embodiment, the case where the inspection schedule creation device 3 is configured independently of the central monitoring device 2 has been described. However, the inspection schedule creation device 3 may be incorporated in the central monitoring device 2.
Further, in the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.
