Description

The present invention relates to an instrument transformer combination checking system and checking method for checking and confirming whether the combination is correct when a meter such as a watt-hour meter and a transformer (current transformer) are used in combination.

Traditionally, when installing or replacing meters and transformers, it has been necessary to match their capacities and multipliers and combine them. For this reason, when unloading from a power company's warehouse to a construction company, the person in charge visually confirms whether the combination of meters and transformers is correct based on the construction request form, and the construction company also , workers visually checked whether the combination was correct based on the construction request form. However, not only is it time-consuming and labor-intensive to check by a worker, but also the checking is done visually, so there is a risk that a checking error may occur.

Against this background, an instrument miscombination prevention system that can prevent incorrect combinations of meters and transformers is known (for example, see Patent Document 1). This system attaches association barcode information to the combined instrument and transformer, and when the association barcode information is read and transmitted with a mobile phone at the installation site, etc., it is possible to check whether the combination of the instrument and transformer is correct or not. It will be checked and the results will be sent to your mobile phone.

That is, electric power company C selects and combines a meter K and a transformer H having a predetermined capacity, multiplication factor, etc. based on the construction application details (power contract type, contract capacity, etc.), and the management computer 2 selects and combines them. Generate and store relevant information.

The related information is information provided in the combined meter K and transformer H to associate the meter K and transformer H (indicating that the two are combined), and in this embodiment, The construction receipt number, combination number (the same number given to both the combined instrument K and transformer H to make it clear), the identification information of the combined instrument K and transformer H, the details of the work, etc. include.

Here, the installation location and installation date may be included in the related information, but in this embodiment, the installation location and installation date are included in the construction information separately from the related information, as will be described later. That is, the construction information includes the installation location, installation date, etc. in addition to related information, and is generated and stored by the management computer 2. Further, a plurality of transformers H may be combined with one meter K in some cases.

Such related information is encoded by the management computer 2 to generate and print two-dimensional codes 31 and 32. That is, the two-dimensional codes 31 and 32 are two-dimensional codes in which related information is encoded, the two-dimensional code for meters 31 is pasted on the surface of the meter K, and the two-dimensional code for transformers 32 is for transformation It is pasted on the surface of the vessel H. Then, the meter K, the transformer H, and the smartphone 4 to be described later, to which the two-dimensional codes 31 and 32 are attached, are delivered from the electric power company C to the office or warehouse of the construction company M. At this time, a construction request form containing the ID, password, reception number, etc. (information to identify the construction work, construction contractor, etc.), installation location, installation date, construction details, etc. to be input in the check application 47 described later. is sent to construction contractor M.

The smartphone 4 is used by a construction contractor M who installs the meter K and the transformer H, and is a multifunctional mobile phone that can obtain the current location and read related information, that is, two-dimensional codes 31 and 32 from the meter K and the transformer H. It's a phone. This smartphone 4 has the same functions and configuration as existing multi-function mobile phones, except that it has a function to check whether the combination of meter K and transformer H is correct, etc., and as shown in Fig. 2. , mainly a communication section 41, a touch panel 42, a clock 43, a GPS section 44, a camera 45, a storage section (construction information storage means) 46, a check application (check means, guide program) 47, and these. It includes a central processing unit 48 that performs control and the like.

The communication unit 41 is an interface for communicating with the outside, and specifically transmits check results, which will be described later, to the management computer 2. The touch panel 42 is a display section and an input section for displaying various information and images, and inputting various information and commands. For example, a guide screen/image by a check application 47, which will be described later, is displayed, and an ID, password, reception number, etc., which will be described later, are input.

The clock 43 is a device that constantly measures the current time, and also measures the current date, year, month, and day. The GPS unit 44 is a functional unit for detecting its own position (capable of acquiring the current position), and receives time signal radio waves from GPS (Global Positioning System) satellites to obtain current position information ( It calculates and obtains latitude, longitude) in real time. The camera 45 is a device that takes pictures, and in this embodiment, mainly reads the related information of the meter K and the transformer H from the two-dimensional codes 31 and 32 by taking pictures of the two-dimensional codes 31 and 32. It is something.

The storage unit 46 is a memory that stores various information and data, and mainly stores construction information. Specifically, as shown in FIG. 3, for each combination of meter K and transformer H (for each reception number), related information 461, installation location 462, installation date 463, and other construction information 464 are stored. There is.

The related information 461 stores related information about the combined instrument K and transformer H, that is, construction reception number, combination number, identification information of the combined instrument K and transformer H, construction details, etc. . The installation location 462 stores the location (latitude, longitude) where this meter K and transformer H should be installed, and the installation date 463 stores the date when this meter K and transformer H should be installed. (If a time is specified, the time is also stored.)

Such construction information is stored in the smartphone 4 when delivered from the electric power company C to the construction contractor M, and construction information regarding the meter K and the transformer H installed by the construction contractor M at the delivery destination is stored. That is, when the instrument K and the transformer H are delivered to the construction contractor M as described above, the construction information of the corresponding instrument K and transformer H stored in the management computer 2 is stored in the smartphone 4, and the construction information is stored in the smartphone 4 and delivered to the construction contractor M. Delivered to M.

The check application 47 is an application that guides operations such as reading and determining related information on the screen (on the touch panel 42) and determines whether the combination of the meter K and transformer H that is to be installed is correct.・It is a program. That is, it is activated when an activation command is input on the touch panel 42, and when a predetermined operation is performed according to the guidance screen on the touch panel 42, the related information read with the smartphone 4, the current position, and the reading date are stored in the storage unit 46. It is determined whether the related information included in the construction information matches the installation location and installation date. At this time, multiple sets of related information can be read, and a determination is made for each of the read multiple sets of related information.

Specifically, first, a first screen (login screen) as shown in FIG. When the password is entered and the "Login" button on the screen is pressed, a second screen as shown in FIG. 5 is displayed on the touch panel 42. Next, when the "Enter reception number" button on the screen is pressed, a third screen as shown in FIG. When the "reception number" is entered and the "input complete" button on the screen is pressed, a fourth screen as shown in FIG. 7 is displayed on the touch panel 42.

This screen has four "combination check" buttons, and if multiple sets of instruments K and transformers H are included in one construction application (reception number), the number of combinations corresponding to the number of sets is included. The "Combination Check" button is activated and displayed. FIG. 7 illustrates a case where one construction application includes only one set of instrument K and transformer H, and one "check combination" button is activated. Then, when the activated "Combination Check" button is pressed, a fifth screen as shown in FIG. 8 is displayed on the touch panel 42.

Next, when the "QR code capture (instrument)" button on the screen is pressed ("QR code" is a registered trademark), the camera 45 is activated, and as shown in the sixth screen of FIG. When the two-dimensional instrument code 31 of the instrument K is photographed, the screen returns to the fifth screen in FIG. Similarly, when the "QR code capture (current transformer/transformer)" button is pressed, the camera 45 is activated, and when the two-dimensional transformer code 32 of the transformer H is captured by the camera 45, the image shown in FIG. Return to the fifth screen. Here, if there are two combined transformers H, another "QR code capture (current transformer/transformer)" button will be activated and displayed, and the two-dimensional transformer 32 is photographed.

In this way, when the two-dimensional codes 31 and 32 are photographed and the related information of the meter K and transformer H is read, and the "Combination check" button on the screen shown in FIG. 8 is pressed, the read related information and the current It is determined whether the position and reading date match the related information included in the construction information in the storage unit 46, the installation location, and the installation date. That is, it is determined whether the read related information matches the related information of the construction information and the combination of the meter K and the transformer H is correct for the construction object/reception number.

Further, it is determined whether the current position determined by the GPS unit 44 when reading the two-dimensional codes 31 and 32 matches the installation location of the construction information. Furthermore, check whether the date/year/month/day indicated by the clock 43 when reading the two-dimensional codes 31 and 32 matches the installation date of the construction information (if the time is specified, also the time). judge.

As a result, if any one of them does not match, an error message indicating what does not match is displayed on the touch panel 42. Subsequently, if multiple sets of meters K and transformers H are included in one construction application, the screen returns to the screen shown in FIG. 7, and such a combination check is repeated for each set. When all checks are completed, a seventh screen as shown in FIG. 10 is displayed on the touch panel 42. When the "Send results" button is pressed on this screen, the check results (are the combinations correct, the check location/installation location correct, the check date/installation date correct) are sent to the management computer 2, and the results shown in Figure 4 This will return you to the login screen.

Next, a method for checking the combination of instrument transformers using the system 1 for checking combinations of instrument transformers having such a configuration will be described.

First, as mentioned above, electric power company C selects and combines meter K and transformer H, generates and prints related information and two-dimensional codes 31 and 32, and pastes them on meter K and transformer H. Construction information including related information, installation location, and installation date is stored in the storage unit 46 of the smartphone 4. Then, these meter K, transformer H, smartphone 4, and construction request form are delivered from electric power company C to construction contractor M.

Next, the construction contractor M goes to the installation site on the installation date stated in the construction request form, starts the check application 47 on the smartphone 4, and reads the two-dimensional code from the meter K and transformer H according to the screen guidance as described above. 31 and 32, that is, read related information. Thereby, it is determined whether the read related information, current position, and reading date match the related information stored as construction information, the installation location, and the installation date. Then, by performing a predetermined operation, the check results are sent to the management computer 2, that is, the electric power company C. Upon receiving this, the electric power company C stores the check results etc. in the management computer 2, and also makes sure that related information etc. match. If not, take the prescribed measures. Furthermore, the construction contractor M returns the smartphone 4 to the electric power company C.

As described above, according to the instrument transformer combination check system 1 and the instrument transformer combination check method, when the construction contractor M reads the two-dimensional codes 31 and 32, that is, related information, from the instrument K and transformer K with the smartphone 4, It is determined whether the read related information matches the related information included in the construction information stored in advance, that is, whether the combination of the meter K and the transformer M is correct. Furthermore, it is determined whether the current location of the smartphone 4 matches the installation location included in the pre-stored construction information, that is, whether or not related information is being read from the meter K and the transformer M at the installation location. . In this way, since it is determined whether the combination is correct at the correct installation location (just before or after installation) (so that there will be no mistakes in the combination afterwards), the combination of instrument K and transformer M is It becomes possible to properly check whether it is correct.

Moreover, whether or not the reading date on which the relevant information was read by the smartphone 4 matches the installation date included in the pre-stored construction information, that is, whether the relevant information was read from the meter K and the transformer M on the installation date. It is determined whether or not there is. In this way, since it is determined whether the combination is correct on the correct installation date (just before or after installation) (so that there will be no mistakes in the combination afterwards), the combination of instrument K and transformer M is It becomes possible to check whether the information is correct or not.

Further, since multiple sets of related information can be read by the smartphone 4 and determination is made for each set, it is possible to reduce the effort and time required for checking. For example, even when multiple sets of meters K and transformers M are installed at the same installation location, it is possible to check multiple sets at once.

Further, since operations such as reading and determining related information are guided on the screen of the touch panel 42, anyone can easily and appropriately perform operations such as reading and determining related information according to this case.

Although the embodiments of this invention have been described in detail above, the specific configuration is not limited to this embodiment, and even if there are changes in the design within the scope of the gist of this invention, Included in invention. For example, in the above embodiment, the smartphone 4 is equipped with a construction information storage means and a checking means, but in preparation for the management computer 2, the management computer 2 performs a combination check and sends the determination result to the smartphone 4. It may also be displayed on the touch panel 42. In addition, although related information is pasted on the instrument K and transformer H as two-dimensional codes 31 and 32, the related information is simply identification information, equipment number, etc., and the identification information of the combined instrument K and transformer H is used. may be stored as construction information. Alternatively, the matching number may simply be used as related information. Further, instead of the two-dimensional codes 31 and 32, a bar code, an IC (Integrated Circuit) tag, or the like may be used.
