Description

  The present invention relates to an electric meter maintenance management business system used for maintenance management of an electric meter.

  Do electrical meters that measure electricity, such as measuring electricity used at customer facilities, comply with the technical standards stipulated by the Measurement Act by public institutions (Nippon Electric Meters Laboratory, hereinafter referred to as NIPPON TEST)? Tests have been conducted to determine whether or not. The measuring accuracy of the electric meter is publicly proved by the test, and accurate weighing is performed.

There are various types of such electric meters according to the scale of power demand of consumers, and they are roughly classified into single electric meters and electric meters with transformers.
A single electric meter is an electric meter that measures the amount of electricity used by a mechanical type or an electronic type alone, and only a watt hour meter is provided for each type of equipment. By class, there are only ordinary watt-hour meters, and by phase line, there are single-phase two-wire, single-phase three-wire, three-phase three-wire, and three-phase four-wire.

  An electric meter with a transformer is an electric meter that measures using a mechanical or electronic combination electric meter and a transformer (instrument transformer and instrument current transformer). There are wattmeters, watt-hour meters, and reactive watt-hour meters. Of these, watt-hour meters are further divided into classes: normal watt-hour meters, precision watt-hour meters, and special precision watt-hour meters. By phase line, single-phase two-wire, single-phase three-wire, and three-phase three-wire・ There are three-phase four-wire systems. In this specification, an electric meter with a transformer and a single electric meter are collectively referred to simply as an electric meter.

  Such electric meters have received the above-mentioned type approval / certification by the NIPPON DENKO when shipped from the factory, and can be installed and used immediately in customer facilities. This certification has a valid period (hereinafter referred to as the valid examination period), and existing products that are installed and measured at customer facilities must be replaced with the certified electric meter before the valid period expires. is there.

  Therefore, the electric power company that manages the electric meter currently performs revocation management to manage the verification validity period of the existing electric meter, and before the expiration of the verification validity period (hereinafter referred to as expiration), Instead of a meter, a verified electrical meter is installed, and the removed electrical meter is re-verified and reused elsewhere.

  Such revocation management of an electric meter is automatically performed using a computer or the like in the prior art. For example, in Patent Document 1 (name of invention: electronic measuring instrument and automatic meter reading system), data such as the expiration date of an electronic measuring instrument is automatically obtained from an automatic meter reading device center computer in connection with the automatic meter reading system. A storage system is disclosed.

JP 2001-297390 A (paragraph numbers 0019 to 0034, FIGS. 1 and 2)

  In the maintenance management of electric meters, not only the above-described invalidation management but also the management for recycling the removed electric meters is performed. For example, even if the removed electric meter is immediately verified, the period of not being used becomes long if there is no installation location, and the verification period is wasted. Therefore, store until the location where the electrical meter can be installed appears, perform verification when the applicable location appears, recycle it, and effectively use the electrical meter throughout the verification period. New electric meters are purchased and replenished only when new electric meters are needed.

  As described above, in the maintenance and management of electric meters, revocation management, material management, certification management, and construction management are performed. However, these managements are performed manually using a ledger or the like. Since the number of electric meters such as watt hour meters installed at customer facilities is extremely large, these managements are very troublesome.

  In addition, as described above, the electrical meters with transformers are various transformers and maximum demand wattmeters, so that when they are reused, they are optimized according to the customer facilities to be installed. It is necessary to configure a variety of meters such as watt hour meters and reactive watt hour meters, and to further test this electric meter with a transformer by Nichiden Test.

However, considering the contract form of ordinary households, high-voltage, and special high-voltage customers, in addition to performing the optimal combination according to the installation location with hand-held materials, determine whether it is appropriate to combine old electric meters, etc. The combination work was very troublesome work. In addition, since the contents of contracts concluded between customers and electric power companies change with the appearance of new services, new combinations may be required, and this also requires management.
Furthermore, because the verification mode of verification differs depending on the combination of electrical meters with transformers, verification management may be affected.

  In this way, it is difficult to manage the maintenance of electric meters in general. While power companies outsource part of such management to subcontractors, they are making intensive efforts to improve management efficiency, such as improving management efficiency. There was a need for measures to improve work efficiency and reduce document emissions.

  Further, it is conceivable to deal with the system like the electronic measuring instrument and the automatic meter reading system described in Patent Document 1, but there is no system that performs these managements at the same time.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to integrate the management of a plurality of electric meters so as to improve the efficiency of maintenance and management work of the electric meters. It is to provide a maintenance management business system.

  According to the present invention as described above, it is possible to provide an electric meter maintenance management business system that integrates the management of a plurality of electric meters and improves the efficiency of the maintenance management business of the electric meters.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of an electric meter maintenance management business system according to the present embodiment, FIG. 2 is an explanatory diagram explaining a data structure, FIG. 3 is an explanatory diagram explaining a data flow, and FIG. 4 is an explanatory diagram of an allocation logic. .

The electric meter maintenance management business system 100 includes a revocation management system 10 and a terminal device 11 at a power company head office sales department, a material management system 20 and a terminal device 21 at a power company head office material department, and a construction management system at a power company shop. 30 and a terminal device 31 are provided by an affiliated company with an instrument selection system 40, a certification management system 41, and a terminal device 42, which are connected by a dedicated network 50 and can communicate with each other.
Further, the construction management system 30 is connected to the terminal device 70 of the construction company via the public network 60 and can communicate therewith.
Further, these terminal devices 11, 21, 31, 42, and 70 are connected to data input through a keyboard (not shown), data display by a display (not shown), or a printer (not shown). Printing is possible. It is also connected to a system at the same location so that it can communicate on the premises.

The revocation management system 10 is a system for managing revocation, and is installed, for example, in the power company head office sales department.
The material management system 20 is a system for managing electric meters owned by an electric power company, and is installed, for example, in the electric power company head office material department.
The construction management system 30 is a system for managing construction arrangements such as ordering from a construction contractor, and is installed in, for example, a power company store.
The meter selection system 40 is a system for selecting and managing a single electric meter or an optimum electric meter with a transformer according to a newly installed location by newly establishing or revoking. ing.
The certification management system 41 is a system that manages a series of certification procedures for electric meters that perform certification, and is installed, for example, in a power company's partner company.
The dedicated network 50 is, for example, a line using an optical fiber laid together with an electric wire on a support of an electric power company, and is a line that enables high-speed data transmission over a long distance.

  A subcontractor is a company outsourced by an electric power company. For example, a subcontractor is an electric meter certification agency, an electric meter repair company, an electric meter overhaul company (for example, an electric meter that is an example of an electric meter). Dismantling, cleaning, exchanging some consumables, refurbished processing company after completion of certification), electric meter contracted construction company (for example, installation / removal replacement or attachment of watt hour meter as an example of electric meter) Equipment contractors) Other companies involved in maintenance management work.

  In FIG. 1, it is assumed that the instrument selection system 40 and the certification management system 41 are separately installed in the partner company. However, these are functionally separated, and the instrument selection system 40 and the certification management system 41 may be processed by a single computer device having a high processing capacity. In this case, this computer device is connected to the dedicated network 50 alone.

Next, electric meter maintenance management processing by such a system will be described.
First, the revocation management system 10 in FIG. 1 refers to revocation management data registered in an instrument management database (not shown) when a predetermined date and time (for example, at the end of each month) is reached. As shown in FIG. 2A, the expiration management data includes contractor data, contract content data, instrument data accompanied by transformer data, verification expiration date data, and other detailed data.

  The revocation management system 10 extracts revocation management data relating to an electric meter that is subject to revocation, generates meter data, and temporarily stores it in the data storage unit of the system. And the instrument data by the display of the display of the terminal device 11 and the printing of the printer can be output. The revocation management system 10 transmits the instrument data to the instrument selection system 40 in response to an instruction from the power company head office sales department or automatically (such as (1) in FIG. 3). Thereafter, the instrument selection system 40 can be accessed from the terminal device 31 of the electric power company store in charge of maintenance for invalidation replacement, and the instrument data can be confirmed. The instrument data is obtained by extracting a part of the invalidation management data and has a data structure as shown in FIG. The terminal device 31 and the instrument selection system 40 receive instrument data.

The power company store can grasp the schedule of the invalidation replacement work from the instrument data obtained by the display on the terminal device 31 and the printing by the printer.
On the other hand, the instrument selection system 40 outputs instrument data by display on the terminal device 42 and printing by the printer. The partner company confirms the contents of the output instrument data.

Subsequently, the instrument selection system 40 performs the allocation work. Here, the instrument selection system 40 stores reference data for allocation as shown in FIGS. 4 (a) and 4 (b).
For example, if it is understood from the contract content data of the meter data in FIG. 2 (a) that it is a single electric meter frequently used for general households, as shown in FIG. 4 (a), the reference for the single electric meter is used. Execute allocation logic to refer to the data. For example, if the meter data is A1, the electric meter of B1 is allocated from the corresponding single electric meter data, and the newly installed electric meter is determined.

If it is found from the contract data of the meter data in FIG. 2 (a) that the electrical meter is equipped with a transformer, first, an allocation logic that refers to the reference data for the electrical meter with transformer shown in FIG. 4 (b). I do.
For example, if the transformer data is C1 and the transformer data is C1, the transformer-equipped electrical meter D1 is allocated from the corresponding transformer-equipped electrical meter data, and the transformer-equipped electrical equipment to be newly installed and used is used. Determine the type of instrument.
The transformer-equipped electric meter D1 includes data that can be specified for the transformer and the electric meter combined with the transformer (for example, the transformer D1A and the electric meter D1B combined with the transformer).

The instrument selection system 40 generates procurement instrument data or procurement transformer data (see FIG. 2B) for the electrical instrument allocated in this way.
Note that the procurement data for the meter and the transformer are independent for the sake of procurement.

  The meter selection system 40 determines whether the electric meter or transformer combined with the assigned transformer is a special item or a stored item. The special product is a product that needs to be purchased again, and is described as special data in reference data (not shown).

The stored items are processed as follows, and in the case of separate items, since the material management system 20 is a dedicated storage item system, it is individually handled.
The meter selection system 40 generates meter procurement request data indicating that an electrical meter is procured. The instrument procurement request data has a data structure as shown in FIG. 2B, for example, and includes contractor data, contract contents data, procurement instrument data, procurement transformer data, verification expiration date data, and detailed data. .
The instrument procurement request data is transmitted to the material management system 20 of the head office material department of the electric power company ((2) in FIG. 3).

  In the material management system 20, when the instrument procurement request data transmitted from the instrument selection system 40 is received, the material management system 20 performs a process of arranging for delivery at the material management center of the material department of the power company and delivery to the partner company. Such a delivery may be automatically performed by transferring the instrument procurement request data to a terminal device installed in the material management center. After the delivery process ends, the material management system 20 transmits the meter delivery schedule data to the certification management system 41 ((3) in FIG. 3). This confirms the delivery of the electric meter to the partner company. The instrument delivery schedule data has a data structure as shown in FIG. 2 (c), for example, contractor data, contract content data, procurement instrument data, procurement transformer data, verification expiration date data, detailed data, delivery Scheduled date data and delivery location data are provided. Here, for the convenience of delivery, the delivery data of the single electrical meter, the combined electrical meter and the transformer is made independent.

  In some cases, the subcontractor has a material management center and manages it on its behalf. In such a case, the power company's material management department issues the goods to the subcontractor's material management center, and in-house instrument procurement request data. It is only to confirm. In this case, the subcontractor may perform comprehensive management including overhaul operations.

  In addition, in the material management system 20, when the instrument procurement request data transmitted from the terminal device 31 is received, it is determined that it is a special item, and the single electric meter and the combined electric meter and the transformer in a predetermined format are: You may make it arrange so that it may order to a manufacturer and it may deliver to a cooperation company. Such ordering can also be automatically performed by transferring instrument procurement request data to a terminal device installed at the manufacturer. Then, the material management system 20 transmits the instrument delivery schedule data to the certification management system 41. This confirms the delivery of the electric meter to the partner company.

  Regardless of whether it is a stored item or a special item, an electric meter is delivered to a subcontractor.In the case of an electric meter with a transformer, the combination of the transformer and the combined electric meter is within the allowable range of the instrument accuracy. A test is conducted to confirm. When the person in charge of the partner company operates the terminal device 42 to access the verification management system 41, the verification management system 41 creates document data for the application for verification of the electric meter determined using the meter delivery schedule data. The data is transferred to the device 42 and is output to the printer using the document data.

Then, submit an electric meter along with the application documents to Nidec. After passing the certification and returning to the partner company again, the electrical instrument is shipped to the power company store or material center. Then, the power company store operates the terminal device 31 and makes a response by e-mail or electronic ordering with the construction company terminal device 70 via the construction management system 30 and the public network 60 to conclude a contract. . After that, the electric instrument is delivered from the power company store, and the construction company performs an expiration replacement work to replace the electric instrument.
If a contract is already concluded before shipment, the electric instrument may be delivered directly from the partner company to the construction company.

  The series of processes has been described above. In this embodiment, the revocation management system 10 has been described as transmitting instrument data to the terminal device 31 of the power company store and the terminal device 42 of the partner company. However, in addition to the invalidation replacement, a new installation when installing an electrical instrument when a new building is created, a capacity replacement when increasing or decreasing the capacity of an electrical instrument, a fault replacement when an electrical instrument fails, an electrical instrument When changing to a new form, there is still a remaining period until completion, but there is an exceptional revocation that precedes the revocation exceptionally due to construction reasons. In this case, at the power company store, Instrument data is generated from the terminal device 31 and transmitted to the instrument selection system 40 of the partner company (arrow (a) by dotted line in FIG. 3). Thereafter, the verified electric meter is delivered by following the same workflow (2) → (3), and it is possible to request the construction company to perform the construction.

  In this way, management data is centrally managed and shared not only between each department of the electric power company but also with subcontracting companies, so that the revocation management data of the vast number of electric meters allocated to consumers is regularly It is possible to retrieve revocation management data whose expiration date is close to expiration and extract meter data, and to efficiently perform maintenance management operations such as verification of electric meters and replacement work of electric meters.

  Such partner companies include, for example, partner companies that carry out verification work in a lump sum, such as verification fees, repairs, overhauls, construction, etc., partner companies that have advanced technology and can quickly deal with repairs of precision electric meters, Or, there are subcontractors that specialize in replacement work of electric meters to customers, but obtain the estimate and delivery date data of the certification commissioning work in advance, select the optimal subcontractor, at low cost and with a reliable construction period, You may make it perform the maintenance management work of an electric meter systematically.

  Furthermore, when business operators such as electric power companies outsource verification fees, repairs, overhauls, construction and other maintenance management to the outside, they adjust the data necessary for the estimate and take security measures. It is possible to build a business method linked to billing procedures and inter-bank procedures by recruiting bids.

  The business owner builds a business system that covers the overall maintenance and management related to the present invention, and centrally manages and shares various data for managing electric meters between each department of the business owner and the subcontractor. Enter the form of the person in charge, telephone or fax. The amount of work such as contact / confirmation and delivery of documents can be reduced, and in particular, meter verification can be performed quickly and efficiently.

  At the same time, when a business owner entrusts a part of maintenance management work such as verification fee, repair, overhaul, construction, etc. to a subcontractor, it is linked to a business fee system that has a settlement function for billing procedures and interbank transactions. However, it is possible to establish business methods related to business transactions with appropriate partner companies that have secured low-cost, short-term work, and excellent technology.

It is a block diagram of the electric meter maintenance management business system of the best form for implementing this invention. It is explanatory drawing explaining a data structure. It is explanatory drawing explaining the flow of data. It is explanatory drawing of the logic for allocation.
