Description

Instrument management system and instrument management portable terminal

Technical Field

The invention relates to an instrument management system and an instrument management portable terminal.

Background

In a building, a meter for looking up tables (hereinafter, referred to as "actual meter") of electricity, gas, tap water, and the like is generally installed for each customer who enters the building, and a fee is collected based on a value (referred to as "actual meter value") obtained by looking up the table of the actual meter. There are also buildings in which an automatic table look-up meter (referred to as a "BAS meter") provided in a Building management system (BAS) is introduced in addition to an actual meter. The BAS meter value (referred to as "BAS meter value") is transmitted to a building management system and displayed on a PC (Personal Computer) installed in, for example, a central monitoring room.

In the table lookup of the actual meter, it is common to confirm the consistency of the actual meter value with the BAS meter value. The consistency confirmation is performed, for example, by a maintenance person who performs a table lookup of the actual meter notifying a maintenance person in front of the BAS meter of the read actual meter value with a mobile phone, and the maintenance person in front of the BAS meter comparing the BAS meter value with the read actual meter value. However, this confirmation operation requires two maintenance personnel to perform, and is inefficient.

Patent document 1 describes a method in which one maintenance worker confirms the consistency between the actual meter value and the BAS meter value. The maintenance person holds a hand-held terminal as a wireless terminal device provided in the building management system, and inputs an actual meter value and reads an ID of the actual meter using the hand-held terminal. The hand-held terminal sends the actual meter value and the ID to a central management device of the building management system. In this case, the central management device stores the transmitted actual meter value in association with the ID, and calculates the difference between the actual meter value obtained in the previous table lookup and the actual meter value obtained in the present table lookup. In addition, the central management device calculates a difference between the BAS table value in the last table lookup and the BAS table value in the present table lookup. The two calculated difference results are output to a display device or a printing device of the central management device. The maintenance personnel who finished the table look-up of the actual meters return to the central monitoring room to observe the output results to confirm the consistency of the actual meter values with the BAS meter values.

Patent document 2 below also discloses a case where one maintenance person confirms the consistency between the actual meter value and the BAS meter value. The maintenance person first reads the BAS meter and inputs the BAS meter value to a portable terminal such as a PC. Then, the maintenance person performs a table lookup of the actual meter, and inputs the read actual meter value to the portable terminal. The maintenance personnel then read the BAS meter again and enter the BAS meter value into the portable terminal. In the portable terminal, the change in the BAS meter value at two times is compared with the actual meter value obtained by table lookup therebetween, and it is confirmed whether or not the changes match.

Disclosure of Invention

Problems to be solved by the invention

Patent document 1 mentioned above is a system in which a maintenance person cannot confirm the consistency with the BAS meter when looking up a table of actual meters. In this system, it is assumed that maintenance personnel first perform a centralized table lookup service, and then perform a matching confirmation service of actual meter values and BAS meter values before moving to the central management apparatus. Therefore, the maintenance personnel can concentrate on each job, but if the inconsistency is known, the maintenance personnel need to go again to confirm the actual meter.

In patent document 2, the maintenance worker needs to input the BAS meter value to the portable terminal twice, and the work process is complicated. In addition, the patent document 2 is configured such that, similarly to the patent document 1, when a maintenance person checks a table of actual meters, the maintenance person cannot confirm the consistency with BAS data in the portable terminal at hand. Patent document 2 also describes a configuration in which a maintenance person inputs only an actual meter value into a portable terminal, and a comparison between the BAS meter value input and the actual meter value is performed on the central management apparatus side, but the configuration is not changed in that the maintenance person cannot confirm the consistency when looking up the actual meter.

As in patent documents 1 and 2, in a system in which a maintenance worker moves to a central monitoring room after looking up a table of actual meters and performs consistency comparison with BAS meters, time required for the maintenance worker to move is wasted. In particular, in a large building, a movement time of several tens of minutes may be required for the movement from the central monitoring room to the actual meter. Therefore, in order for a maintenance person to efficiently confirm the consistency between the actual meter value and the BAS meter value, it is necessary to review the conventional business process to a large extent.

The invention aims to review the service flow under the condition that one maintainer confirms the consistency of the actual instrument value and the BAS instrument value, thereby improving the efficiency.

Means for solving the problems

An instrument management system according to a first aspect is characterized by comprising: an actual meter value acquisition unit that acquires an ID of an actual meter and an actual meter value based on a user operation of the mobile terminal; a BAS meter value acquisition unit that acquires a BAS meter value corresponding to the ID and corresponding to the acquisition time of the actual meter value; a storage unit that stores the actual meter value and the BAS meter value in association with the ID; an actual difference value calculation unit that calculates an actual meter difference value, which is a difference between the actual meter value acquired this time and the actual meter value acquired last time, for the ID; a BAS difference calculation unit that calculates a BAS meter difference, which is a difference between the BAS meter value acquired this time and the BAS meter value acquired last time, for the ID; a determination unit that compares the actual meter difference value with the BAS meter difference value and determines consistency between the actual meter value and the BAS meter value; and a display unit that displays the result of the determination on the mobile terminal.

In the meter management system according to the second aspect, the actual meter value acquisition unit further acquires date and time information of a stage at which the actual meter value is input to the portable terminal, and the BAS meter value acquisition unit acquires the BAS meter value corresponding to the date and time information.

In the meter management system according to a third aspect, the actual meter value acquisition means further acquires a picture of the actual meter taken at the time of the current acquisition in the portable terminal, and the display means further displays an operation button for displaying the pictures of the actual meter at the time of the current acquisition and at the time of the previous acquisition.

The meter management system according to a fourth aspect is characterized by comprising a sharing means for displaying a result of the determination by the determination means on a portable terminal other than the portable terminal, and sharing information.

A meter management portable terminal according to a fifth aspect of the present invention is characterized by comprising: an input unit that inputs an ID of an actual meter and an actual meter value according to a user operation; an actual display unit that displays, for the ID, the actual meter value input this time, the actual meter value input last time, and an actual meter difference value that is a difference therebetween; a BAS display unit that displays, for the ID, a BAS meter value at the current input time, a BAS meter value at the previous input time, and a BAS meter difference value that is a difference therebetween; and a determination display unit that displays a consistency determination result based on a comparison of the actual meter difference value and the BAS meter difference value.

Effects of the invention

According to the first aspect of the present invention, the maintenance person who performs table lookup of the actual meter can quickly know the result of the consistency determination after table lookup. Therefore, when the consistency is negative, the actual meter can be confirmed again immediately.

According to the second aspect of the present invention, since the consistency check with the BAS meter value is performed based on the date and time of the input stage of the actual meter value, even when the communication state is poor and communication cannot be performed during the table lookup of the actual meter, for example, after the communication state is restored, the consistency check can be performed collectively for the actual meters which have been subjected to the table lookup up to that point in time.

According to the third aspect of the present invention, when the coincidence is negated, the photograph at the stage of inputting the actual meter value can be confirmed, and the task of finding the problem can be made efficient.

According to the fourth aspect of the present invention, the latest determination result can be shared among a plurality of maintenance persons. Therefore, even when a plurality of maintenance workers perform work by assigning the sharing range of the actual meter to the large-scale building, for example, each maintenance worker can easily grasp the entire state.

According to the fifth aspect of the present invention, the meter management portable terminal used by the maintenance person displays not only the result of the consistency determination but also the numerical value based thereon, and therefore, the maintenance person can easily estimate the problem point when the consistency is denied.

Detailed Description

The following describes embodiments with reference to the drawings. In the description, specific embodiments are shown for easy understanding, but these are merely exemplary embodiments, and various embodiments may be adopted.

Fig. 1 is a diagram showing a schematic configuration of an instrument management system 10 according to an embodiment. The instrument management system 10 includes a building 20, a PC30, a smartphone 40, a server 50, a network 70, and maintenance personnel 80.

An electrical device 22 that introduces electricity from the outside is installed on the roof of the building 20, and the electrical device 22 is provided with an actual meter 24 as an electricity meter. The actual meter 24 is provided with a display unit 24a for displaying the measured amount of electricity and a display field 24b for identifying the id (identification) of the actual meter 24. The actual meters 24 are set according to different occupants of the building 20, and each actual meter 24 is given an ID. The electricity fee of each of the entrants is determined based on the actual meter value which is the look-up table value of the actual meter 24.

The BAS26, which is a building management system, is imported into the building 20. The BAS26 is a system for monitoring and controlling various building devices such as electricity, air conditioners, lighting, and elevators in a centralized manner. In the BAS26, for example, a central management device is installed in a central monitoring room underground in a building, and the central management device is connected to building equipment so as to be able to communicate with the building equipment, and monitors and controls the building equipment. The central management apparatus operates by controlling computer hardware including a memory, a processor, and a communication circuit with software including an Operating System (OS) and an application program (application).

The BAS26 is provided with a BAS meter 28 that independently performs a table lookup on the electrical equipment 22 for each occupant. The BAS meter 28 acquires the automatic table lookup result at short time intervals (for example, 5 seconds) and detects an abnormality or the like. The table lookup result can be displayed in real time in accordance with the ID of the occupant, and can be recorded at appropriate time intervals. In addition, the IDs of the occupants in the BAS meters 28 are typically chosen to be different from the IDs of the actual meters 24, but in one-to-one correspondence. Therefore, in the embodiment, for the sake of simplicity of explanation, the same ID is used for both IDs.

The PC30 is a terminal device for maintenance management. The PC30 operates by controlling computer hardware including a memory, a processor, and a communication circuit with software including an Operating System (OS) and application programs (applications). In fig. 1, the PC30 is configured to be able to communicate with the BAS26 through a wired connection, and is configured to be able to communicate with the server 50 through the network 70 using a wireless connection such as LTE (Long Term Evolution). The PC30 can take BAS data values from BAS26 through an application.

The smartphone 40 is an example of an instrument management portable terminal, and is a portable terminal device held by the maintenance person 80. The smartphone 40 operates by controlling computer hardware including a memory, a processor, and a communication circuit with software including an Operating System (OS) and an application program (application). In the example of fig. 1, the smartphone 40 is configured to be able to communicate with the server 50 via the network 70 using wireless communication such as LTE. The maintenance personnel 80 perform a lookup of the actual meters 24 using the smartphone 40 and confirm compliance with the BAS meters 28. Details of the operation will be described later.

The server 50 is a device that operates by controlling computer hardware including a memory, a processor, and a communication circuit with software including an Operating System (OS) and an application program (application). Since the server 50 is applied to management of a plurality of facilities including the building 20, in the embodiment, not only the case where the server is installed in the building 20 but also the case where the server is installed in a remote maintenance management company or the like is assumed. However, the server 50 is not particularly limited to an installation location as long as it can communicate with the network 70. The server 50 is applied to construct each function of the actual meter value acquisition unit 52, the BAS meter value acquisition unit 54, the storage unit 56, the difference calculation unit 58, the determination unit 60, and the output unit 62.

The actual meter value acquisition unit 52 is an example of an actual meter value acquisition means that acquires information on the ID, the actual meter value, the photograph of the actual meter 24, and the date and time at which the transmission instruction from the smartphone 40 was made, which are transmitted from the smartphone 40, via the network 70. The acquired actual meter value and the photograph are stored in the storage unit 56 in association with the ID.

The BAS meter value acquisition unit 54 is an example of a BAS meter value acquisition unit, and transmits information of the ID and the date and time acquired by the actual meter value acquisition unit 52 to the PC30 via the network 70. Then, the BAS meter value acquisition unit 54 acquires the BAS meter value at the date and time from the PC30 for the ID. The acquired BAS meter value is stored in the storage unit 56 in association with the ID.

The storage unit 56 is an example of a storage unit, and is a storage device constructed using a memory such as a semiconductor memory or a magnetic disk. The date and time, the actual meter value, the photograph of the actual meter 24, and the BAS meter value are stored in the storage unit 56 in association with the ID.

The difference calculation unit 58 is an example of an actual difference calculation unit and a BAS difference calculation unit, and calculates a difference between the actual gauge value and the BAS gauge value. Specifically, the actual meter value is calculated as the difference between the actual meter value acquired this time and the actual meter value acquired last time (this is referred to as "actual meter difference value") stored in the storage unit 56. The BAS meter value is calculated as a difference between the currently acquired BAS meter value and the last acquired BAS meter value (referred to as "BAS meter difference") stored in the storage unit 56.

The determination unit 60 is an example of a determination means that compares the actual meter difference calculated by the difference calculation unit 58 with the BAS meter difference and determines whether or not the actual meter value and the BAS meter value match each other. Specifically, when the difference between the actual meter difference and the BAS meter difference is equal to or less than a preset reference value, it is determined that there is coincidence, and when the difference exceeds the reference value, it is determined that there is no coincidence.

The output unit 62 outputs the determination result of the determination unit 60. The output unit 62 is an example of a display unit, and has a function of outputting the determination result to the smartphone 40 via the network 70 and displaying the determination result on the smartphone 40. The output unit 62 is also an example of a sharing means, and has a function of displaying a determination result or the like on a portable terminal or the like different from the smartphone 40. The output unit 62 also outputs the determination result to a PC or the like connected to the server 50 in response to the request.

The network 70 is a communication line that can be connected from the PC30, the smartphone 40, and the server 50. The maintenance worker 80 is an operator who performs maintenance management of the building 20.

Next, the operation of the meter management system 10 will be described with reference to fig. 2A to 2D and fig. 3. Fig. 2A to 2D are diagrams showing examples of screens of the smartphone 40 in chronological order, and fig. 3 is a diagram showing an example of data stored in the storage unit 56 of the server 50.

In the instrument management system 10, first, the maintenance person 80 moves to the roof of the building 20 with the smartphone 40. The smartphone 40 is in a state in which a plurality of applications can be selected. In FIG. 2A, launch icons for applications of A service 100, B service 102, C service 104, and lookup check service 106 are shown. The maintenance person 80 selects an icon for the lookup table check service 106.

In this case, in the smartphone 40, the lookup table checks that the business application is started. Then, as shown in fig. 2B, the meter retrieval tool 110 is displayed on the smartphone 40. The registered facilities such as building a, building B, and building C are displayed in the meter search tool 110. Fig. 2B shows the result of selection of building C, showing a state in which floors 1F to 5F of building C are displayed. The maintenance person 80 appropriately performs a scroll operation, selects a floor on which a table is to be looked up, displays a list of entrants, and then determines the targeted entrant.

Note that, although fig. 2B shows the meter search using the meter search tool 110, the meter search may be performed by another method. For example, a method of reading an ID storage medium such as a barcode, a two-dimensional code (QR code), or a Radio Frequency Identifier (RFID) provided near the actual meter 24 may be used.

Fig. 2C shows a state of a screen displaying the meter search result and the fellow passenger with ID "12345". On this screen, an input field 120 for inputting the current look-up table value (expressed as "current value" in fig. 2C) and a keyboard 122 for inputting are displayed for the actual meter. The input field 120 and the keyboard 122 are examples of input means, and the maintenance worker 80 reads the number "11860.1" from the display portion 24a of the actual meter 24 shown in fig. 1 and operates the keyboard 122 to input the number into the input field 120.

The screen shown in fig. 2C also displays a photograph taking button 124 and a sending button 126. The maintenance person 80 operates the photo shooting button 124 to start the camera of the smartphone 40 and shoot the actual meter 24. The taken picture (here assumed to be a still image) is temporarily stored inside the smartphone 40. In this state, when the maintenance person 80 operates the send button 126, information of the ID information, the actual meter value input to the input field 120, the photograph of the actual meter 24, and the send date and time of the send button 126 is sent to the server 50.

Here, an example in which the maintenance person 80 inputs the actual meter value into the input field 120 through the keyboard 122 is shown, but the input may be performed by another method. For example, there is a method of acquiring an actual meter value by performing OCR processing on a photograph obtained by taking the actual meter 24.

In the server 50, the actual meter value acquisition unit 52 acquires the ID, the actual meter value, the photograph, and the transmission date and time transmitted from the smartphone 40, and stores them in the storage unit 56. Fig. 3 shows an example of data 150 about ID "12345" stored in the storage section 56. The data 150 is provided with an ID column 152, a date and time column 154, an actual meter value column 156, a BAS meter value column 158, an actual meter photograph column 160, and a determination result column 162.

The ID column 152 is a column showing which ID the data 150 is data about. In the example of fig. 3, the ID field 152 stores an ID of "12345".

The date/time column 154 records the date and time acquired by the actual meter value acquisition unit 52 of the server 50. In the example shown in fig. 3, date and time "45 minutes 35 seconds at 21 st 9/6 th year 2019", "21 minutes 28 seconds at 22 st 10/7 th year 2019", "53 minutes 02 seconds at 21 st 9/8 th year 2019" are displayed. Note that the date and time may be measured on the same basis every time, and the date and time when the transmission button 126 of the smartphone 40 is pressed may be replaced with the date and time when the input of the actual meter value to the smartphone 40 is completed, the date and time when the photograph is taken, or the like. By using the date and time on the smartphone 40 side, even when the state of the radio wave is poor and the reception at the server 50 is delayed, the input time of the actual meter value can be appropriately grasped.

The actual meter value column 156 stores the actual meter value obtained from the smartphone 40. The actual meter photograph field 160 stores a photograph of the actual meter acquired from the smartphone 40.

When the ID, date and time, actual meter value, and photograph are acquired from the smartphone 40, the server 50 immediately acquires the BAS meter value corresponding to the ID and date and time from the PC 30. The obtained BAS meter value is stored in the BAS meter value column 158. Further, when the acquisition interval of the BAS meter values acquired by the PC30 is large, the PC30 may not have the BAS meter value at the date and time requested by the server 50. Then, the PC30 may transmit the latest BAS meter value, for example, to the server 50 when the date and time requested by the server 50 is traced back. Alternatively, BAS meter values obtained by linear interpolation or linear extrapolation from BAS meter values at two times around the date and time may be transmitted. In short, the PC30 transmits the BAS meter values obtained with the same reference to the server 50 every time.

In the server 50, the difference calculation unit 58 calculates the actual meter difference and the BAS meter difference, and the determination unit 60 determines the difference. Then, the output unit 62 of the server 50 transmits the calculation result and the determination result to the smartphone 40. The determination result is stored in the determination result field 162 of the data 150.

Fig. 2D shows an example of a screen displayed on the smartphone 40 after the send button 126 is pressed in fig. 2C. Fig. 2D shows a screen of the fellow passenger with ID "12345" as in fig. 2C, and also shows the input field 120 of the present lookup value for the actual meter. Also, fig. 2D shows a thumbnail 130 of the photograph taken this time. Further, fig. 2D shows a display field 132 for displaying the last actual meter value, a thumbnail 134 of the last actual meter photograph, and a display field 136 for displaying the actual meter difference value, which are transmitted from the server 50. The input field 120 and the display fields 132 and 136 are examples of actual display means.

In the example shown in fig. 2D, the actual meter value at this time is 11860.1(kWh), the actual meter value at the last time is 10449.4(kWh), and the actual meter difference value is 1410.7 (kWh). In the case where the displayed value is perceived to be different, the maintenance person 80 can operate the

thumbnail image

130 or 134 to display a larger-sized photograph and confirm the value.

In fig. 2D, the BAS meter is displayed in the current BAS meter value display field 138, the last BAS meter value display field 140, and the BAS meter difference display field 142. The

display columns

138, 140, 142 are examples of BAS display units. In the example shown in fig. 2D, the BAS meter value at this time is 11859.7(kWh), the BAS meter value at the last time is 10448.9(kWh), and the BAS meter difference is 1410.8 (kWh).

Further, fig. 2D also shows the determination result. In the example shown in fig. 2D, a "good" display 144 is shown, indicating that the actual meter is consistent with the BAS meter. This is because the difference between the actual meter difference and the BAS meter difference is 0.1kWh and equal to or less than a reference value (e.g., 0.5kWh or 1.0 kWh), and it is determined that there is coincidence. The display 144 is an example of a determination display unit.

If the difference between the actual meter difference value and the BAS meter difference value is greater than the reference value, the display is a no display instead of the good display 144. The display of "no" is performed, for example, in such a manner that the attention of the maintenance person 80 is drawn by red or the like. In this case, the maintenance person 80 confirms whether or not the actual meter value input this time is erroneous. The maintenance person 80 can also check the image of the actual meter by operating the

thumbnails

130 and 134. Further, since inconsistency due to the acquisition interval of the BAS meter values is also taken into consideration, the maintenance person 80 can input the actual meter value again immediately or after a lapse of an appropriate time and transmit the actual meter value to the server 50. In this case, the server 50 uses (in the example of fig. 3) data at a date of about one month before, instead of the previously transmitted data, as the previous data, calculates the difference value, and performs the re-determination.

In the above description, the maintenance person 80 inputs the actual meter value and immediately transmits it to the server 50 after taking the actual meter photograph. However, when the state of the radio wave is poor in the smartphone 40, the transmission to the server 50 cannot be performed immediately. Therefore, the smartphone 40 has a function of automatically transmitting to the server 50 at the time of return of the state of the radio wave.

In the smartphone 40, when the data accumulated up to that time is collectively transmitted to the server 50 at the time of the state recovery of the radio wave, the determination process in the server 50 is also collectively performed. Therefore, the determination results regarding the plurality of IDs are transmitted from the server 50 to the smartphone 40 at the same time. Therefore, the smartphone 40 also has a function of displaying a list of results transmitted from the server 50.

Fig. 4 shows an example of a screen for displaying a list of determination results transmitted from the server 50 in the smartphone 40. The smartphone 40 displays a list 170 of the determination results. In the list 170 shown in the figure, only the determination that ID "12346" is "no", that is, it is determined that the actual meter value does not match the BAS meter value, and all the others are determined to be "good". The maintenance person 80 operates the column of the ID "12346" in the list 170 to display the ID "12345" in detail as shown in fig. 2D.

The list 170 shown in fig. 4 can be displayed not only on the smart phones 40 held by the maintenance staff 80 but also on smart phones held by other maintenance staff. This enables information sharing by a plurality of maintenance workers. This is particularly effective where the building 20 is large scale. In a large-scale building 20, the number of occupants is large, and the number of actual meters 24 may exceed 1000. Therefore, the plurality of maintenance workers often share and perform the table lookup operation for each area. In this case, by enabling the smartphone of each maintenance worker to display the list 170 of all occupants of the building 20, it is possible to easily grasp the range that is not implemented or implemented, and to confirm the consistency between the actual meter value and the BAS meter value within the implemented range. The transfer of the service from a certain maintenance person to other maintenance persons becomes smooth. Further, when a system error occurs in the real meter 24 of a plurality of entrants, each maintenance worker can grasp the problem in front of the real meter 24 and promptly take action for coping with the problem.

The list 170 as shown in fig. 4 can be output not only to the smartphone 40 but also to a PC or the like. The PC or the like can obtain the determination result of all the entrants of the building 20 and the like by accessing the data 150 or the like described in fig. 3 stored in the storage unit 56 of the server 50. This makes it possible to easily perform a report generation operation for maintenance and inspection of the building 20.

In the above description, the electricity meter is taken as an example of the actual meter 24. However, this embodiment can also be applied to other instruments such as gas and tap water.
