Description

This invention relates to a monitoring device and a monitoring method for monitoring and reading meters.

Conventionally, there is known a monitoring system in which meter terminals (hereinafter simply referred to as meters) such as gas meters and water meters are monitored and read by a central monitoring device (see, for example, Patent Document 1). By reading the meters, the amount of usage of a target object (water, gas, electricity, etc.) during a target period (meter reading period) is obtained, and the obtained usage amount is used to bill users of the target object (tenants, etc.).

However, it is stipulated by law that the meters must be replaced at regular intervals (for example, every 8 to 10 years) regardless of whether or not the user is billed. Generally, records relating to meter replacement (hereinafter referred to as meter replacement records) are entered by the operator into a monitoring device for each meter and managed by the monitoring device. Here, the meter replacement records include, for example, the meter replacement date, the reading before replacement, and the reading after replacement. The reading before replacement is the meter reading when the meter replacement work begins, and the reading after replacement is the meter reading when the replacement work is completed.

Patent No. 3862638

In a billing monitoring system, if a meter is replaced within a target period, an operator may manually input the meter replacement record into the monitoring device in order to calculate the correct usage amount of the target object. However, meter replacement work is often performed at night when users are not using the target object, and during that time, an operator who is not familiar with facility management may be in charge of inputting the meter replacement record. In such cases, there is a problem that an operator who is not familiar with facility management may incorrectly input the meter replacement record into the monitoring device.

This invention was made to solve the above problems, and aims to provide a monitoring device that can obtain meter replacement records more accurately than ever before.

The monitoring device of the present invention comprises an instruction receiving unit that receives, for each meter to be monitored, a first instruction indicating the start of replacement or a second instruction indicating the end of replacement; a pre-replacement reading value acquisition unit that, when the first instruction for the meter is accepted by the instruction accepting unit, acquires the reading value of the meter at the time the first instruction is accepted as a pre-replacement reading value; a replacement date acquisition unit that, when the first instruction for the meter is accepted by the instruction accepting unit, acquires the date on which the first instruction was accepted as the replacement date of the meter; and a post-replacement reading value acquisition unit that, when the second instruction for the meter is accepted by the instruction accepting unit, acquires the reading value of the meter at the time the second instruction was accepted as a post-replacement reading value. When a second instruction for a meter is received by the instruction receiving unit, the replacement date acquisition unit acquires the date on which the second instruction was received, checks whether the date on which the second instruction was received is different from the date on which the first instruction obtained by the replacement date acquisition unit was received, and if the date on which the second instruction was received is different from the date on which the first instruction obtained by the replacement date acquisition unit was received, acquires the date on which the second instruction was received as the replacement date for the meter.

With the above-mentioned configuration, this invention makes it possible to obtain meter replacement records more accurately than ever before.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
Embodiment 1.
FIG. 1 is a diagram showing an example of the configuration of a monitoring system including a monitoring device according to a first embodiment.

As shown in FIG. 1, the monitoring system includes one or more meter reading meters 1, one or more controllers 2, one or more sub-controllers 2b, and a monitoring device 3. The meter reading meter 1 is connected to the sub-controller 2b via a communication line. The sub-controller 2b is connected to the controller 2 via a communication line. The controller 2 is also connected to the monitoring device 3 via a communication line. FIG. 1 shows one meter reading meter 1, one sub-controller 2b, and one controller 2.

The meter reading 1 updates the meter value according to the usage of the target object, and transmits data indicating the current meter value to the sub-controller 2b. The target object may be a fluid such as water or gas, or electricity. The meter reading meter 1 may be, for example, a communication meter or a pulse meter.

For example, the communication meter updates the meter value by incrementing the reading by one when the target object is used to a certain extent. Then, for example, when the meter value is updated, the communication meter transmits data (message) indicating the current meter value to the sub-controller 2b.

The pulse meter also updates the meter value by incrementing the reading by one when the target object is used a certain amount, and transmits a pulse signal indicating the current meter value to the subcontroller 2b, for example, at the time the meter value is updated.

The sub-controller 2b manages the target meter 1. For example, if the meter 1 is a communication meter, the sub-controller 2b receives data (message) from the communication meter and acquires the meter value indicated by the data. If the meter 1 is a pulse meter, the sub-controller 2b receives a pulse signal from the pulse meter and acquires the meter value indicated by the pulse signal. The sub-controller 2b then updates the current meter value with the acquired meter value, and transmits data indicating the current meter value to the controller 2, for example, in response to an acquisition request from the controller 2, via communication such as Modbus or PLC (programmable logic controller).

The controller 2 manages the target meter 1 via the subcontroller 2b. For example, the controller 2 receives data from the subcontroller 2b by making a request to the subcontroller 2b to obtain the meter value at a predetermined interval (for example, every 10 seconds), and obtains the meter value indicated by the data, i.e., the meter value transmitted from the meter 1 to the subcontroller 2b, as a reading. The controller 2 then updates the current reading with the obtained reading. The controller 2 then transmits data indicating the current reading to the monitoring device 3 in response to an acquisition request from the monitoring device 3, for example, by communication such as BACnet (Building Automation and Control Network).

Note that existing meter reading meters, subcontrollers, and controllers can be used as the meter reading meter 1, subcontroller 2b, and controller 2.

The monitoring device 3 monitors and reads the target meter 1 via the controller 2 and sub-controller 2b. As shown in FIG. 2, the monitoring device 3 includes a storage unit 301, an acquisition unit 302, a usage calculation unit 303, an instruction reception unit 304, a pre-replacement reading acquisition unit 305, a replacement date acquisition unit 306, a post-replacement reading acquisition unit 307, a display control unit 308, and a display unit 309.

The storage unit 301 stores various data handled by the monitoring device 3. The storage unit 301 is configured with an SSD (Solid State Drive), a DVD (Digital Versatile Disc), memory, etc.

The storage unit 301 stores various information (e.g., meter ID, etc.) related to the target meter 1 as the metering point of the meter 1. The storage unit 301 also stores data indicating the readings acquired by the acquisition unit 302 in chronological order as metering point data.

The storage unit 301 also stores data indicating the usage calculated by the usage calculation unit 303 in chronological order as meter reading data. The storage unit 301 also stores data indicating the pre-replacement reading acquired by the pre-replacement reading acquisition unit 305, data indicating the replacement date acquired by the replacement date acquisition unit 306, and data indicating the post-replacement reading acquired by the post-replacement reading acquisition unit 307 in chronological order as meter replacement records.

In FIG. 2, the holding unit 301 is shown provided inside the monitoring device 3. However, this is not limiting, and the holding unit 301 may be provided outside the monitoring device 3.

The acquisition unit 302 receives data from the controller 2 by making a request to acquire a reading value (scanning, etc., if there are multiple controllers 2) to the controller 2 at a predetermined cycle (e.g., every 60 seconds) and acquires the reading value indicated by the data. In other words, the acquisition unit 302 acquires the meter value of the meter reading meter 1. Note that, in the following, for ease of explanation, the acquisition unit 302 acquiring a reading value from the controller 2 at a predetermined cycle as described above will be referred to as "periodic acquisition".

The usage calculation unit 303 calculates the usage during the target period (meter reading period) based on the results of acquisition by the acquisition unit 302. At this time, the usage calculation unit 303 calculates the usage during the target period by, for example, calculating the degree to which the readings acquired by the acquisition unit 302 during regular acquisition have increased during the target period.

The instruction receiving unit 304 receives a first instruction indicating the start of replacement or a second instruction indicating the end of replacement for each meter reading meter 1 to be monitored. At this time, the instruction receiving unit 304 may receive the first instruction or the second instruction from the operator via, for example, a metering point monitoring screen (described below) displayed on the display unit 309.

When the instruction receiving unit 304 receives a first instruction for the meter 1, the pre-replacement reading value acquisition unit 305 acquires the reading value of the meter 1 at the time the first instruction is received as a pre-replacement reading value. The pre-replacement reading value acquisition unit 305 acquires the pre-replacement reading value from the controller 2, but this acquisition of the pre-replacement reading value is performed when the instruction receiving unit 304 receives the first instruction, and is performed separately from the periodic acquisition by the acquisition unit 302.

When the instruction receiving unit 304 receives a second instruction for the meter 1, the post-replacement reading value acquisition unit 307 acquires the reading value of the meter 1 at the time the second instruction was received as a post-replacement reading value. The post-replacement reading value acquisition unit 307 acquires the post-replacement reading value from the controller 2, but the acquisition of the post-replacement reading value by the post-replacement reading value acquisition unit 307 is also performed separately from the periodic acquisition by the acquisition unit 302.

When the instruction receiving unit 304 receives a first instruction for the meter reading meter 1, the replacement date acquisition unit 306 acquires the date on which the first instruction was received as the replacement date for the meter reading meter 1. At this time, the replacement date acquisition unit 306 acquires, for example, the system date of the monitoring device 3 as the replacement date for the meter reading meter 1.

When a second instruction for the meter reading meter 1 is received by the instruction receiving unit 304, the replacement date acquisition unit 306 acquires the date on which the second instruction was received. Then, when the date on which the second instruction was received differs from the date on which the first instruction acquired by the replacement date acquisition unit 306 was received, the replacement date acquisition unit 306 acquires the date on which the second instruction was received as the replacement date for the meter reading meter 1.

The display control unit 308 causes the display unit 309 to display a metering point monitoring screen that displays the meter replacement record. The meter replacement record is, for example, the pre-replacement reading acquired by the pre-replacement reading acquisition unit 305, the replacement date of the meter 1 acquired by the replacement date acquisition unit 306, and the post-replacement reading acquired by the post-replacement reading acquisition unit 307.

The display unit 309 is configured, for example, by a monitor. FIG. 2 shows a case where the display unit 309 is provided inside the monitoring device 3. However, this is not limited thereto, and the display unit 309 may be provided outside the monitoring device 3.

The functions of the acquisition unit 302, the usage calculation unit 303, the instruction reception unit 304, the pre-replacement reading acquisition unit 305, the replacement date acquisition unit 306, the post-replacement reading acquisition unit 307, and the display control unit 308 are realized, for example, by a central processing unit (CPU) (not shown) provided in the monitoring device 3 executing a predetermined program deployed in a memory (not shown).

Note that FIG. 1 shows a case where a sub-controller 2b is provided in the monitoring system. However, this is not a limitation, and the monitoring system does not necessarily have to be provided with a sub-controller 2b. In this case, the meter reading meter 1 is connected to the controller 2 via a communication line. If the meter reading meter 1 is a communication meter, the communication meter transmits data (message) indicating the current meter value to the controller 2, for example, when the meter value is updated. If the meter reading meter 1 is a pulse meter, the pulse meter transmits a pulse signal indicating the current meter value to the controller 2, for example, when the meter value is updated.

Next, an overview of an example of the operation of the monitoring device 3 according to the first embodiment will be described with reference to FIG. 3. In FIG. 3, the horizontal axis indicates time, and the vertical axis indicates the reading value.

First, at point a, the operator issues a first instruction to the meter 1 to start replacement. When the monitoring device 3 receives the first instruction at the instruction receiving unit 304, the monitoring device 3 acquires the pre-replacement reading value of the meter 1 at the pre-replacement reading value acquisition unit 305. In addition, the monitoring device 3 acquires the date on which the first instruction was received as the replacement date of the meter 1 at the replacement date acquisition unit 306.

After that, in period b, the replacement work of the meter reading 1 is carried out. When the replacement work is completed, the operator issues a second instruction to the meter reading 1 at point c, indicating the completion of the replacement. When the monitoring device 3 receives the second instruction at the instruction receiving unit 304, the post-replacement reading value acquisition unit 307 acquires the post-replacement reading value of the meter reading meter (actually the meter reading meter after replacement), and the replacement date acquisition unit 306 acquires the date on which the second instruction was accepted. At this time, the replacement date acquisition unit 306 checks whether the date on which the second instruction was accepted is different from the replacement date of the meter reading meter 1 acquired at point a (the date on which the first instruction was accepted), and if the two dates are different, the date on which the second instruction was accepted is acquired as the replacement date of the meter reading meter 1. If the two dates are the same, the replacement date acquisition unit 306 leaves the replacement date of the meter reading meter 1 as the date on which the first instruction was accepted.

Next, a specific example of the operation of the monitoring device 3 according to the first embodiment will be described with reference to Figures 4A and 4B. Figure 4A is a diagram for explaining steps ST401 to ST407 of a specific example of the operation of the monitoring device 3, and Figure 4B is a diagram for explaining steps ST408 to ST413 of a specific example of the operation of the monitoring device 3. Note that, for ease of understanding, a case where a meter reading meter 1a due for replacement is replaced with a new meter reading meter 1b will be described as an example. Also, here, it is assumed that the operator has previously identified that the meter to be replaced is the meter reading meter 1a, for example, via a specified screen displayed on the display unit 309, and that this identification has caused the metering point monitoring screen to be displayed on the display unit 309.

Here, an example of the metering point monitoring screen is shown in Figure 5. As shown in Figure 5, the metering point monitoring screen is displayed for the meter reading meter 1a that has been identified by the operator as the meter to be replaced, and a check box 501 labeled "Meter replacement" is displayed in the tag column at the top. This check box 501 is blank in the initial state. In addition, a column for displaying "Meter replacement record" is provided at the bottom of the metering point monitoring screen, and the meter replacement record obtained by the monitoring device 3 is displayed in this column.

In addition, here, the first instruction indicating the start of the exchange is executed by the operator, for example, by checking a check box 501 on the weighing point monitoring screen displayed on the display unit 309, and the second instruction indicating the end of the exchange is executed by the operator changing the check box 501 from on to off.

When the instruction receiving unit 304 receives a first instruction, it sets the replacement mode of the target meter reading meter 1a to enabled, and when it receives a second instruction, it changes the replacement mode of the target meter reading meter 1a from enabled to disabled. The replacement mode is a mode that indicates whether the meter reading meter 1a is undergoing replacement work or not. This replacement mode can be set individually for the metering point of each meter reading meter 1, and is set to disabled in the initial state.

Note that, here, an example is described in which the first instruction and the second instruction are given by the operator by turning on and off the check box 501, but the first instruction and the second instruction are not limited to this, and may be given by a method other than turning on and off the check box 501.

First, in response to the operator identifying meter reading meter 1a as the meter to be replaced, the display control unit 308 causes the display unit 309 to display a metering point monitoring screen for meter reading meter 1a (step ST401).

Then, the instruction receiving unit 304 receives a first instruction indicating the start of replacement for the meter reading meter 1a (step ST402). Here, the instruction receiving unit 304 receives the first instruction by the operator checking a predetermined check box in the metering point monitoring screen displayed on the display unit 309. At this time, the instruction receiving unit 304 sets the replacement mode of the meter reading meter 1a to active.

Next, the pre-replacement reading acquisition unit 305 acquires the reading of the meter 1a when the first instruction is received by the instruction receiving unit 304 in step ST402 as the pre-replacement reading (step ST403).

Next, the replacement date acquisition unit 306 acquires the date on which the first instruction was accepted by the instruction acceptance unit 304 in step ST402 as the replacement date of the meter reading meter 1a (step ST404). Note that the order of steps ST404 and ST403 may be reversed, or steps may be performed simultaneously (including approximately simultaneously).

Next, the display control unit 308 displays the pre-replacement reading value acquired by the pre-replacement reading value acquisition unit 305 and the replacement date of the meter reading meter 1a acquired by the replacement date acquisition unit 306 on the metering point monitoring screen (step ST405).

Here, FIG. 6 shows an example of the metering point monitoring screen at the end of step ST405. As shown in FIG. 6, on the metering point monitoring screen, a check box 501 named "Meter replacement" has been turned on by the operator. In addition, a column for displaying "Meter replacement record" is provided at the bottom of the metering point monitoring screen, and the pre-replacement reading value acquired by the pre-replacement reading value acquisition unit 305 ("Pre-replacement value" in FIG. 6) and the replacement date of the meter reading meter 1a acquired by the replacement date acquisition unit 306 ("Replacement date" in FIG. 6) are displayed in this column.

After the replacement mode is enabled, the actual meter replacement work is performed on-site. Note that even during this replacement work, the monitoring device 3 continues to periodically acquire readings by the acquisition unit 302 (acquiring readings at a predetermined interval from the controller 2). This allows the monitoring device 3 to check whether the new meter 1b and the controller 2 are connected so that they can communicate with each other, for example, when a new meter 1b is installed as a result of replacement work.

When the meter replacement work is completed, the operator changes the check box 501 in the metering point monitoring screen displayed on the display unit 309 from on to off. This causes the instruction receiving unit 304 to receive a second instruction indicating completion of replacement for the meter reading meter 1a (step ST406). At this time, the instruction receiving unit 304 changes the replacement mode of the meter reading meter 1a from enabled to disabled.

Next, the post-replacement reading value acquisition unit 307 acquires the reading value of the meter 1b when the second instruction is received by the instruction receiving unit 304 as the post-replacement reading value (step ST407).

Next, in step ST406, the replacement date acquisition unit 306 acquires the date on which the second instruction was accepted by the instruction acceptance unit 304 (step ST408). Note that steps ST408 and ST407 may be performed in the opposite order, or may be performed simultaneously (including approximately simultaneously).

Next, the replacement date acquisition unit 306 checks whether the date on which the second instruction was received, acquired in step ST408, is different from the replacement date of the meter reading meter 1a acquired in step ST404 (the date on which the first instruction was received) (step ST409).

As a result, if the date on which the second instruction was received is different from the replacement date of the meter reading meter 1a (the date on which the first instruction was received) (step ST409; YES), the replacement date acquisition unit 306 acquires the date on which the second instruction was received as the replacement date of the meter reading meter 1a (step ST410).

For example, meter replacement work is usually performed at night when the use of the target object (water, gas, electricity, etc.) is stopped, and the work often takes about a few hours. However, there are cases where the meter replacement work takes a long time and ends on the day after the work started. In such cases, it is desirable to set the replacement date of the meter reading meter 1a to the date when the work actually ended (the date when the second instruction was received). Therefore, in such cases, the replacement date acquisition unit 306 acquires the date when the second instruction was received as the replacement date of the meter reading meter 1a.

Next, the display control unit 308 displays the post-replacement reading acquired by the post-replacement reading acquisition unit 307 on the metering point monitoring screen, and updates the replacement date of the meter reading meter 1a displayed on the metering point monitoring screen to the date on which the second instruction was received (step ST411).

On the other hand, if the date on which the second instruction was received is the same as the replacement date of the meter 1a (the date on which the first instruction was received) (step ST409; NO), the display control unit 308 displays the post-replacement reading acquired by the post-replacement reading acquisition unit 307 on the metering point monitoring screen (step ST412).

Here, FIG. 7 shows an example of the metering point monitoring screen at the end of step ST412. As shown in FIG. 7, on the metering point monitoring screen, the operator has changed the check box 501 at the top of the screen from on to off. Also, in "Meter replacement record" at the bottom of the metering point monitoring screen, the post-replacement reading value acquired by the post-replacement reading value acquisition unit 307 ("Post-replacement value" in FIG. 7) is displayed. Note that, although the replacement date has not been updated in FIG. 7, if the date on which the second instruction was received is different from the replacement date of the meter reading meter 1a (the date on which the first instruction was received), the replacement date is updated to the date on which the second instruction was received.

The display control unit 308 may display the pre-replacement value and the post-replacement value on the weighing point monitoring screen in a manner that allows the operator to correct them. For example, as shown in FIG. 7, the display control unit 308 may display the pre-replacement value and the post-replacement value in a spin box with an increase/decrease button, and allow the operator to correct the pre-replacement value and the post-replacement value by operating the increase/decrease button.

Correction of the pre-replacement and post-replacement values may be necessary, for example, when a pre-replacement reading value has been agreed upon in advance with a user (e.g., a tenant owner) prior to replacing the meter, but the first instruction is actually executed late. In this case, the pre-replacement reading value acquired by the monitoring device 3 will be larger than the pre-replacement reading value that was agreed upon in advance, and so correction of the acquired pre-replacement reading value may be necessary.

Alternatively, if the execution of the second instruction is delayed after the completion of the meter replacement work, and the meter value of the newly read meter has increased to a certain extent, and the second instruction is executed, the post-replacement reading value acquired by the monitoring device 3 is no longer the original value, it may be necessary to correct the acquired post-replacement reading value. To be able to handle these cases, the display control unit 308 may display the pre-replacement value and the post-replacement value on the metering point monitoring screen in a manner that allows the operator to correct them.

Next, the display control unit 308, in response to an instruction from the operator, causes the display unit 309 to display a metering point monitoring screen that displays the final meter replacement record (step ST413). An example of the display of the metering point monitoring screen in this case is shown in FIG. 8. The operator can use this screen to check the final meter replacement record (replacement date, pre-replacement value, and post-replacement value).

As described above, according to the first embodiment, the monitoring device 3 includes an instruction receiving unit 304 that receives a first instruction indicating the start of replacement or a second instruction indicating the end of replacement for each meter to be monitored, a pre-replacement reading value acquisition unit 305 that acquires the reading value of the meter reading meter 1 when the first instruction is accepted by the instruction accepting unit 304 as a pre-replacement reading value when the instruction accepting unit 304 accepts the first instruction for the meter reading meter 1, a replacement date acquisition unit 306 that acquires the date on which the first instruction is accepted as the replacement date of the meter reading meter 1 when the instruction accepting unit 304 accepts the first instruction for the meter reading meter 1, and a post-replacement reading value acquisition unit 307 that acquires the reading value of the meter reading meter 1 when the second instruction is accepted by the instruction accepting unit 304 as a post-replacement reading value when the instruction accepting unit 304 accepts the second instruction for the meter reading meter 1. This allows the monitoring device 3 to acquire meter replacement records more accurately than ever before.

The monitoring device 3 also includes a display control unit 308 that causes the display unit 309 to display a metering point monitoring screen that displays the pre-replacement reading acquired by the pre-replacement reading acquisition unit 305, the replacement date of the meter 1 acquired by the replacement date acquisition unit 306, and the post-replacement reading acquired by the post-replacement reading acquisition unit 307. This allows the operator to easily check the meter replacement record.

Furthermore, when a second instruction for the meter reading meter 1 is received by the instruction receiving unit 304, the replacement date acquisition unit 306 acquires the date on which the second instruction was received, and when the date on which the second instruction was received differs from the date on which the first instruction acquired by the replacement date acquisition unit 306 was received, the replacement date acquisition unit 306 acquires the date on which the second instruction was received as the replacement date for the meter reading meter 1. This allows the monitoring device 3 to accurately acquire the replacement date for the meter reading meter 1 even if the replacement work for the meter 1 spans multiple dates.

The display control unit 308 also displays a check box 501 for accepting a first instruction or a second instruction on the metering point monitoring screen, and the instruction accepting unit 304 accepts a first instruction when the check box 501 displayed on the metering point monitoring screen is turned on, and accepts a second instruction when the check box 501 displayed on the metering point monitoring screen is turned from on to off. This allows the operator to give the first instruction and the second instruction with a simple operation. In particular, the workload of an operator who is not familiar with facility management can be reduced more than in the past. Furthermore, by checking the state of the check box 501, the operator can prevent forgetting to give the second instruction after giving the first instruction.

In addition, when a first instruction for the meter reading meter 1 is received, the instruction receiving unit 304 sets the replacement mode of the meter reading meter 1 to be enabled, and when a second instruction for the meter reading meter 1 is received, the instruction receiving unit 304 changes the replacement mode of the meter reading meter 1 from enabled to disabled. This allows the monitoring device 3 to manage the replacement work of the meter reading meter 1 based on the replacement mode.

In addition, any of the components of the embodiments of the present invention may be modified or omitted within the scope of the invention.
