The facility management apparatus 1 may include various functional units included in a known computer other than the functional units illustrated in FIG. 1, for example, functional units such as various input / output devices and imaging devices.

  The communication I / F unit 100 is an interface that performs communication control with other devices such as the client terminal 30 and the geographic information system 40. As an aspect of the communication I / F unit 100, a network interface card such as a LAN (Local Area Network) card can be employed. For example, the communication I / F unit 100 receives a distribution system information browsing request from the client terminal 30 or transmits display data generated by the control unit 110 to the client terminal 30.

  In addition, the communication I / F unit 100 accesses an external geographic information system 40 (for example, Google (registered trademark) Map or Yahoo (registered trademark) map) under the control of the control unit 110, and the geographic information system 40. The map information 126 provided by is acquired. The control unit 110 stores the map information 126 acquired from the geographic information system 40 in the storage unit 120.

In addition, the control unit 110 includes an extraction unit 114, a specification unit 115, a position change unit 116, an output unit 117, and a display unit 118.

  Various kinds of integrated circuits and electronic circuits can be adopted for the control unit 110. Further, a part of the functional unit included in the control unit 110 may be another integrated circuit or an electronic circuit. For example, an ASIC (Application Specific Integrated Circuit) is an example of the integrated circuit. Examples of the electronic circuit include a central processing unit (CPU) and a micro processing unit (MPU).

  The storage unit 120 is a storage device that stores various programs such as an OS (Operating System) executed by the control unit 110 and an equipment management program. As one mode of the storage unit 120, a storage device such as a semiconductor memory element such as a flash memory, a hard disk, and an optical disk may be used. The storage unit 120 is not limited to the type of storage device described above, and may be a RAM (Random Access Memory) or a ROM (Read Only Memory).

  The storage unit 120 stores map data 121, position information 122, facility information 123, electrical connection information 124, and distribution system information 125 as an example of data used in a program executed by the control unit 110. . The storage unit 120 also stores the map information 126 acquired from the external geographic information system 40, the node list 127 and the difference information 128 generated by the processing of the control unit 110. In addition to the above information, other electronic data, for example, a history of power consumption in the load facility of the customer can also be stored.

  Here, in the facility management apparatus 1 according to the present embodiment, each facility is managed in association with the map data 121 managed by the company. Specifically, the location where the equipment is installed is managed in association with the map data 121. That is, the map data 121 is an example of specific map information. In addition, the distribution system is managed by dividing each of the facilities and the facility management that manages the attribute information of the facilities and the management of the electrical connection that manages the facilities that are electrically connected to each other.

  Among these, for location management, a location “location” where a predetermined facility, for example, a substation, a utility pole, or a transformer, is installed as an entity among the facilities forming the distribution system. In addition, for the management of equipment, equipment “unit” associated with one position among equipment forming the power distribution system and equipment “span” associated with two positions are used as entities. . For managing electrical connections, connection points “nodes” where the facilities are electrically connected and facilities “branches” determined by a plurality of connection points are used as entities.

  FIG. 2 is a diagram illustrating an aspect of an entity. As shown in FIG. 2, as an example of the location, for example, a position where a non-erection facility that is not installed by erection such as a utility pole P, a transformer TR, or the like is installed. In addition, the location category includes a position where a distribution substation (SS: SubStation) (not shown) and a transformer are installed.

  Examples of the unit include a power pole P, a switch SW, a transformer TR, and the like. In addition, the distribution substation, SVR (Step Voltage Regulator), various measuring instruments, etc. which are not illustrated are also included in the category of the unit.

  An example of the span is an electric wire laid in a high-voltage system between the distribution substation and the transformer TR, so-called “high-voltage line WH”. As another example of the span, in addition to the so-called “low-voltage line WL”, the lead-in line and the load facility, in addition to the electric wire laid in the section of the transformer TR and the lead-in line in the low-voltage system between the transformer TR and the load equipment of the customer Electric wires laid in this section, so-called “lead wires”, and the like. In addition, about the electric wires W, such as the high voltage line WH and the low voltage line WL, the number of units erected on the utility pole P, for example, three or two, can be combined and handled as a span.

  As an example of the node, a connection point between the high voltage line WH and the switch SW, a connection point between the high voltage line WH and the transformer TR, and a connection point between the transformer TR and the low voltage line WL shown in the enlarged view 21 in FIG. Is mentioned. In addition, the point where the high voltage line WH21a and the high voltage line WH21b shown in the enlarged view 22 in FIG. 2 are connected is also included in the category of the node. Specifically, even when the high-voltage line WH21a and the high-voltage line WH21b are installed on the power pole P of the mounting column, the high-voltage line WH21a and the high-voltage line WH21b are regarded as being electrically connected, A point where WHs are connected is treated as a virtual node.

  Examples of the branch include the high voltage line WH, the switch SW, the transformer TR, and the low voltage line WL shown in FIG. In addition to this, a distribution substation, a lead-in line, a load facility, etc., not shown, are also included in the category of the branch. In some cases, the facilities located at the end points such as distribution substations and load facilities have only one node.

  These entities such as locations, units, spans, nodes, and branches have the relationships shown in FIG. FIG. 3 is a diagram illustrating an example of the mutual relationship between entities. As shown in FIG. 3, the unit and the span are related in that the position is managed in common with the location. The unit and the span are related to the point that the facilities are managed in common with the branch. Furthermore, the node is related to the point that the connection point is managed in common between the location and the branch.

  Returning to the description of FIG. 1, the location information 122 includes a location table 122 a that manages the location in association with the location in the map data 121.

Further, as will be described later, the power distribution system information 125 includes a current node table 125a and a current branch table 125b.

  Among these, as an aspect of the location table 122a, a table in which items such as a position ID (identifier), position identification, longitude, and latitude are associated can be employed. The “position ID” refers to identification information for identifying a position where equipment is installed in the map data 121. “Position identification” refers to the identification of the type of position, and examples include the types of distribution substation (SS), utility pole (POLE), and load equipment (LOADL). The information stored in the location table 122a is, for example, the position information of a specific facility such as a substation, utility pole, or transformer from another existing system, for example, an existing distribution facility management system that manages facilities of a distribution system. Can be obtained.

  FIG. 4 is a diagram illustrating an example of the location table 122a. For example, the location of the position ID “SS0001” shown in FIG. 4 is located at east longitude 128 degrees 08 minutes 48 seconds 66 and north latitude 50 degrees 27 minutes 23 seconds 016, which means that there is a distribution substation. Further, various IDs illustrated in FIG. 4 and subsequent figures include character strings that can identify the type of equipment such as “SS” representing a distribution substation, “PO” representing a power pole, and load equipment “LL”. Numbering is performed by adding to the head of the character string constituting the ID. These various IDs are not limited to adding a character string that can identify the type of equipment to the head of the character string that constitutes the ID, and may be assigned a value that can be uniquely recognized. In addition, although the case where longitude and latitude were used as an item for specifying the location of the facility is illustrated here, other items such as local coordinate values and addresses can also be used.

  As an aspect of the unit table 123a, a table in which items such as equipment ID, position ID, type, and attribute information are associated can be employed. The “facility ID” refers to identification information for identifying a facility, and only the facility ID of the unit is stored in the unit table 123a. The “type” refers to the type of unit, and examples thereof include a power pole (POLE), a switch (SW), a pole transformer (BANK), and load equipment (LOADL). The “attribute information” refers to information related to the attribute of the unit. For example, the model number and performance of the unit, for example, when the unit is a transformer, the capacity of the transformer is registered. The capacity of such a transformer can be used for calculating the voltage drop when the electrical connection information of the equipment of the current system is extracted. For example, when the unit is a transformer, a resistance value, a reactance value, and a voltage ratio of the transformer are registered. Note that the information stored in the unit table 123a is acquired from, for example, another existing system, such as a distribution facility management system, and the attribute information of the equipment classified into units among the acquired attribute information of the equipment is registered. The

  FIG. 5 is a diagram illustrating an example of the unit table 123a. For example, the unit with the equipment ID “PO0001P1” shown in FIG. 5 is located at the position corresponding to the position ID “PO0001”, that is, 128 degrees 08 minutes 41 seconds 76 east longitude and 50 degrees 27 minutes 23 seconds 021 north latitude shown in FIG. It means that it is a utility pole. Further, the unit of the equipment ID “PO000101” shown in FIG. 5 is located at the position corresponding to the position ID “PO0001”, that is, at 128 degrees 08 minutes 41 seconds 76 east longitude and 50 degrees 27 minutes 23 seconds 021 north latitude shown in FIG. It means a switch. Further, the unit of the equipment ID “PO000701” shown in FIG. 5 corresponds to the position corresponding to the position ID “PO0007”, that is, in the example of FIG. 4, 128 degrees 08 minutes 34 seconds 30 east longitude and 50 degrees 27 minutes 27 seconds 844 north latitude. Means a pole transformer with a resistance value of “36800Ω”, a reactance value of “31300Ω”, and a voltage ratio of 1.

  As an aspect of the span table 123b, a table in which items such as equipment ID, position ID1, position ID2, type, and attribute information are associated can be employed. The “equipment ID” here indicates identification information for identifying the equipment, but only the equipment ID of the span is stored in the span table 123b. “Position ID1” refers to one of the two position IDs associated with the span, and “Position ID2” refers to the other position ID of the two position IDs associated with the span. The “type” refers to the type of span, and examples thereof include high-voltage lines, low-voltage lines, and lead-in lines. “Attribute information” refers to information related to the span attribute. For example, the span model number, thickness, material, span, resistance value per unit (m), reactance value per unit (m), etc. are registered. Is done. Such a span, resistance value per unit, and reactance value per unit can be used to calculate a voltage drop when the electrical connection information of the current system equipment is extracted. The information stored in the span table 123b is acquired from, for example, another existing system, such as a power distribution facility management system, and the attribute information of the equipment classified into the span is registered among the acquired attribute information of the equipment. The

FIG. 6 is a diagram illustrating an example of the span table 123b. For example, the span of the equipment ID “SP0001” shown in FIG. 6 is a three-phase high-voltage line installed in the section corresponding to the position corresponding to the position ID ₁ “SS0001” and the position corresponding to the position ID ₂ “PO0001”. Means. As described with reference to FIG. 4, this interval is from 128 degrees 08 minutes 48 seconds 66 east longitude and 50 degrees 27 minutes 23 seconds 016 north latitude to 128 degrees 08 minutes 41 seconds 76 east longitude and 50 degrees 27 minutes 23 seconds 021 north latitude. Corresponds to the section. Further, the span span, resistance, and reactance of the equipment ID “SP0001” mean “21 m”, “0.220 Ω / km”, and “0.150 Ω / km”, respectively. When the type shown in FIG. 6 is 3H, it means that the span is a single-phase three-wire high-voltage line. When the type is 3L, the span is a single-phase three-wire low-voltage line. If the type is blank, it means that the span is a lead-in line.

  As an aspect of the node table 124a, a table in which items such as a node ID and a position ID are associated can be employed. Such “node ID” refers to identification information for identifying a node. The information stored in the node table 124a is acquired from other existing systems such as a distribution facility management system and a distribution automation system that monitors a distribution system and remotely operates a switch. For example, after a node is extracted from low-voltage system facility information acquired from a distribution facility management system or high-voltage system facility information acquired from a distribution automation system, it is registered in the node table 124a in association with the location of the node. Is done.

  FIG. 7 is a diagram illustrating an example of the node table 124a. For example, the connection point of the node ID “SS0001N01” shown in FIG. 7 is located at the position corresponding to the position ID “SS0001”, that is, 128 degrees 08 minutes 48 seconds 66 east longitude and 50 degrees 27 minutes 23 seconds 016 north latitude shown in FIG. Means to be located. Further, the connection points of the node IDs “PO0001N01” and “PO0001N02” shown in FIG. 7 are the same positions corresponding to the position ID “PO0001”, that is, 128 degrees 08 minutes 41 seconds 76 east longitude and north latitude shown in FIG. It means it is located at 50 degrees 27 minutes 23 seconds 021.

As an aspect of the branch table 124b, a table in which items such as a branch ID, a node ID ₁ , a node ID ₂ , an equipment ID, and an opening / closing section are associated can be employed. Such “branch ID” refers to identification information for identifying a branch. “Node ID ₁ ” indicates one of the two node IDs of the branch, and “node ID ₂ ” indicates the other node ID of the two node IDs of the branch. However, a branch located at an end point such as a distribution substation or a load facility may have a node ID only in either node ID ₁ or node ID ₂ . Also, the “equipment ID” here refers to identification information for identifying the equipment, but the branch table 124b may store either equipment ID or span equipment ID. The “open / close category” refers to the open / close state of the switch of the switch. In this switching category, if the branch is a switch, either “open state” or “closed state” of the switch is registered, but if the branch is other than a switch, it is set to “blank”. The

  The information stored in the branch table 124b is acquired from other existing systems such as a distribution facility management system and a distribution automation system. For example, after the branch is extracted from the information of the low-voltage system equipment acquired from the distribution equipment management system or from the information of the high-voltage system equipment acquired from the distribution automation system, it is registered in the branch table 124b in association with the node of the branch Is done.

FIG. 8 is a diagram illustrating an example of the branch table 124b. For example, the branch with the branch ID “BR0001” illustrated in FIG. 8 means a high-voltage line with the facility ID “SP0001” defined by the node ID ₁ “SS0001N01” and the node ID ₂ “PO0001N01”. Further, the branch with the branch ID “BR0002” shown in FIG. 8 is a switch having the equipment ID “PO000101” defined by the node ID ₁ “PO0001N01” and the node ID ₂ “PO0001N02”, and the switch classification is “1”. Therefore, it means that the switch is closed. In addition, when the switching division shown in FIG. 8 is “0”, it means that the switch is in an open state, and when the switching division is blank, it means that the equipment is not a switch. means. The closed state of the switch is a state in which electricity flows, and the open state is a state in which no electricity flows.

  Next, along with the operation of the equipment management apparatus 1, the search unit 111, the association unit 112, the external map acquisition unit 113, the extraction unit 114, the specification unit 115, the position change unit 116, the output unit 117, and the display unit 118 in the control unit 110. Details will be described.

  FIG. 9 is a flowchart illustrating an operation example of the facility management apparatus 1 according to the embodiment. As illustrated in FIG. 9, the search unit 111 starts from a predetermined node based on the position information 122 and the electrical connection information 124 and searches for an unsearched node among the nodes included in the node combination. Search for a branch corresponding to the combination. Next, the associating unit 112 includes a combination of connection points where the search is performed and the equipment obtained as a result of the search, and the attribute corresponding to the equipment obtained as a result of the search among the attribute information included in the equipment information 123. Correlate information. Thereby, the equipment management apparatus 1 generates the distribution system information 125 in which the current system equipment and the attribute information of the current system equipment that are electrically connected to each other are associated (S1).

  As one aspect, the search unit 111 activates the process when a request for browsing the distribution system information is received via the client terminal 30 or when a certain period has elapsed since the process was executed last time. First, the search unit 111 searches for a position ID whose position type is the distribution substation “SS” among the position IDs stored in the location table 122a. Then, the search unit 111 registers the position ID of the SS searched from the location table 122a in a search list stored in an internal memory (not shown). In this search list, in addition to the SS position ID to be searched, unsearched nodes and branches discovered during the search are registered as needed. Although the case where the SS position ID is searched from the location table 122a is illustrated here, the node ID whose character string starts with “SS” is searched from the node IDs stored in the node table 124a and the branch table 124b. It doesn't matter.

  Subsequently, the search unit 111 selects one SS position ID registered in the search list. Then, the search unit 111 searches for a node corresponding to the position ID of the SS that has been previously selected among the nodes stored in the node table 124a. Then, the search unit 111 registers the record of the node searched from the node table 124 a in the current node table 125 a stored as the distribution system information 125 in the storage unit 120. Further, the search unit 111 registers the node searched from the node table 124a in the search list. When the SS has a plurality of SS banks, records of a plurality of nodes are searched even when a search is performed using one position ID.

Then, the search unit 111 selects one node registered in the search list. Subsequently, the search unit 111 selects a record of a branch having a combination of node IDs including a node that has been previously selected from the branches stored in the branch table 124b, that is, a combination of node ID ₁ and node ID _2. Search for. In addition, the search unit 111 registers the record of the branch searched from the branch table 124 b in the current branch table 125 b stored as the distribution system information 125 in the storage unit 120. Further, the search unit 111 registers the branch searched from the branch table 124b in the search list. At this time, for example, a branch ID or an equipment ID may be registered in the search list.

  Subsequently, the search unit 111 selects one branch registered in the search list. Then, the search unit 111 searches the span table 123b for attribute information corresponding to the facility ID of the branch that has been previously selected. At this time, if the branch is a span, the attribute information can be searched from the span table 123b, but if the branch is a unit, the attribute information cannot be searched. For this reason, when the attribute information cannot be searched from the span table 123b, the search unit 111 searches the unit table 123a for attribute information corresponding to the facility ID of the branch that has been selected first.

  Thereafter, the search unit 111 determines whether or not the branch is a switch when the other node paired with the node used for the search is not blank among the combination of nodes. When the branch is a switch, the search unit 111 determines whether the switch of the switch is in a closed state, that is, whether the switch classification is “1”. At this time, when the switch of the switch is in the closed state, the search unit 111 searches for the record of the other node from the node table 124a because the switch is energized, that is, in the ON state. Then, it is registered in the current node table 125a of the distribution system information 125. Further, the search unit 111 adds the other node as an unsearched node to the search list.

  Then, the search unit 111 repeatedly executes the processes from the selection of the unsearched branch until all the branches registered in the search list are searched. After that, when all the branches registered in the search list are searched, the search unit 111 repeatedly executes the processes from the selection of the unsearched nodes until all the nodes registered in the search list are searched. Then, the search unit 111 repeatedly executes the processing from the selection of the unsearched SS position ID until the search of all the SS position IDs registered in the search list.

  Here, the search processing of the search unit 111 will be described in detail with reference to the tables of FIGS. First, among the position IDs stored in the location table 122a shown in FIG. 4, the position ID “SS0001” whose position type is the distribution substation “SS” is searched. Then, the SS position ID “SS0001” retrieved from the location table 122a is registered in the search list. In this case, since only the SS position ID “SS0001” is registered in the search list, the position ID “SS0001” is selected. In response to this, the node ID “SS0001N01” corresponding to the position ID “SS0001” of the SS that has been previously selected is searched from the nodes stored in the node table 124a illustrated in FIG. Subsequently, the record of the node ID “SS0001N01” retrieved from the node table 124a is registered in the current node table 125a. Furthermore, the node ID “SS0001N01” retrieved from the node table 124a is also registered in the search list. In this case, since only the node ID “SS0001N01” is registered in the search list, the node ID “SS0001N01” is selected.

Then, the equipment having the combination of the node ID ₁ “SS0001N01” and the node ID ₂ “PO0001N01” including the node ID “SS0001N01” that has been previously selected among the branches stored in the branch table 124b shown in FIG. A branch with ID “SP0001” is searched. Then, the record of the branch with the equipment ID “SP0001” retrieved from the branch table 124b is registered in the current branch table 125b. Further, the facility ID “SP0001” retrieved from the branch table 124b is registered in the search list. In this case, since only the facility ID “SP0001” is registered in the search list, the facility ID “SP0001” is selected.

  Then, the span attribute information “span 21 m, resistance RH1, reactance XH1” corresponding to the equipment ID “SP0001” that has been previously selected is retrieved from the span table 123b shown in FIG. Here, the case where the attribute information of the span is searched is illustrated, but in the case of the equipment ID starting with a character string other than “SP”, the attribute information is not searched from the span table 123b, and FIG. The unit attribute information is retrieved from the unit table 123a shown.

  From the attribute information “21 m span, resistance 0.220 Ω / km, reactance 0.150 Ω / km” thus obtained, resistance value 4.621 (0.220 × 21 ÷ 1000) 0.00462 Ω, reactance value 0.003150 (0.150 × 21 ÷ 1000) Ω is registered in the current branch table 125b in association with the branch record of the equipment ID “SP0001” used for the search of the span table 123b.

Thereafter, in the combination of the node ID ₁ “SS0001N01” and the node ID ₂ “PO0001N01”, the node ID “SS0001N01” used for the search is set as “PO0001N01” as the value of the other node ID. . Thus, since the other node ID is not blank, it is determined whether or not the branch of the equipment ID “SP0001” is a switch. The branch of the facility ID “SP0001” has a blank value for the opening / closing section and is not a switch. Therefore, after searching the record of the other node ID “PO0001N01” from the node table 124 a, the record of the other node ID “PO0001N01” is registered in the current node table 125 a of the distribution system information 125. Further, the other node ID “PO0001N01” is added to the search list as an unsearched node.

  Thus, when the other node ID “PO0001N01” is registered in the search list as an unsearched node, no node ID is registered other than the node ID “PO0001N01”. For this reason, the search is continued after the node ID “PO0001N01” is selected.

  Although the case where the other node ID is not blank is illustrated here, when the other node ID is blank, a search for an unsearched branch registered in the search list is executed. If there is no unsearched branch, a search for an unsearched node is executed. If there is no unsearched SS position ID, the search is terminated. In addition, here, the case where the branch is not a switch is illustrated, but in the case of a switch, if the switch of the switch is not closed, the other node ID is searched, and further, the other to the search list is searched. Node addition is not performed. This is because, when the switch of the switch is in an open state, when the other node ID is searched or the other node is added to the search list, a different distribution system that is not electrically connected is displayed in the current node table 125a. This is because they are erroneously registered in the current branch table 125b.

  Returning to the description of FIG. 9, as an aspect of S1, the associating unit 112 associates the record of the branch on which the search has been executed with the attribute information of the branch retrieved from the span table 123b or the unit table 123a. For example, the association unit 112 registers the attribute information of the branch in association with the record of the branch used for searching the span table 123b or the unit table 123a among the records stored in the current branch table 125b. At this time, the associating unit 112 can further associate the position ID after searching for the position ID corresponding to the facility ID of the branch from the unit table 123a or the span table 123b.

  As a result, after the search is completed, as a result of associating the branch record with the branch attribute information in the current branch table 125b, the current system equipment and the current system attribute information that are electrically connected to each other correspond to each other. The attached power distribution system information 125 can be generated.

  Here, the current node table 125a and the current branch table 125b will be described. FIG. 10 is a diagram illustrating an example of the current node table 125a. FIG. 11 is a diagram illustrating an example of the current branch table 125b. FIGS. 10 and 11 illustrate a current node table 125a and a current branch table 125b that are generated using the tables shown in FIGS. 4 to 8 starting from the node ID “SS0001N01”.

  As shown in FIG. 10, nodes "LL0001N01", "LL0002N01", "LL0003N01", "LL0004N01", "LL0005N01" which are connection points between the customer's load facilities and distribution system facilities in the records of the current node table 125a. ”,“ LL0006N01 ”,“ LL0007N01 ”, and“ LL0008N01 ”, the power consumption measured by a measuring instrument such as a smart meter is registered as an example of attribute information. Such power consumption includes “active power” consumed by the load facility and “reactive power” not consumed by the load facility. Among these, reactive power is also called delayed reactive power. These power usage (valid) and power usage (invalid) are referred to when calculating the voltage at each node.

  As shown in FIG. 11, the value of the opening / closing classification registered in the current branch table 125b is registered in the record in which the branch equipment is a switch among the records of the current branch table 125b. For example, since the switches with branch IDs “BR0002”, “BR0006”, and “BR0019” are all registered with “1” in the switching category, the switch of the switch is in the closed state and is in the energized state. Means that. FIG. 11 illustrates a switch whose switching category is “1”, but when the switching category of the switch is “0”, the switch of the switch is open and not energized. Means. Further, the reactance value X and the resistance value R are registered as an example of attribute information in each record of the current branch table 125b. Among these, the reactance value X and the resistance value R registered in the unit table 123a are directly registered as attribute information in equipment whose branch equipment is a unit, such as a switch or a transformer. On the other hand, for a facility whose branch facility is a span, a value obtained by multiplying a reactance value per unit registered in the span table 123b by a value between spans is registered as a reactance value X, and a resistance per unit. A value obtained by multiplying the value by the span value is registered as the resistance value R. The reactance value X and resistance value R of these units and spans are referred to when calculating the voltage at each node.

  In this example, power consumption (effective), power consumption (invalid), resistance value, and reactance value are exemplified as parameters used for voltage calculation, but either current node table 125a or current branch table 125b is used. The voltage can be calculated more precisely by adding a connection phase item to which the transformer is connected to the table. For example, when the electric wire is a single-phase three-wire, the first unit of the transformer connected to the electric wire on the pillar is “connection phase 1”, the second is “connection phase 2”, the third unit Is “connection phase 3”. Also, if a transformer is connected to the first and second of the three wires, the value “A” is registered. If a transformer is connected to the second and third wires, the value “B” is registered. When the transformer is connected to the first and third lines, the value “C” can be registered.

  In the facility management apparatus 1, by using the generated distribution system information 125, a distribution system diagram showing the electrical connection of the distribution system and a facility map showing the location of each facility on the company's map data 121 are created. Can be presented to the client terminal 30. The display unit 118 is a processing unit that generates display data to be displayed on the client terminal 30 and outputs the display data to the client terminal 30 via the communication I / F unit 100, and uses the generated distribution system information 125. Then, display data of the distribution system diagram and equipment map is generated and output to the client terminal 30.

  Specifically, the display unit 118 is a predetermined facility ID among the facility IDs included in the current branch table 125b stored in the storage unit 120, for example, the facility ID of the SS, or any facility that has received designation from the client terminal 30. Select an ID. Then, the display unit 118 sets the node ID closest to the SS among the combination of node IDs associated with the previously selected equipment ID as the root of the hierarchical structure. Subsequently, the display unit 118 lowers the hierarchy given to the nodes as the number of nodes increases from the root toward the equipment ID of the load equipment at the end, and the equipment is arranged between the nodes from the root to the end. Data for displaying the graph structure of the system, that is, display data for the distribution system diagram is generated. Then, the display unit 118 causes the client terminal 30 to display the distribution system diagram by transmitting display data for the distribution system diagram to the client terminal 30. In addition, although the case where the display data is displayed on the client terminal 30 is illustrated here, the display data may be displayed on the display unit included in the facility management apparatus 1.

  12 and 13 are diagrams illustrating an example of a distribution system diagram. 12 and 13 show distribution system diagrams when the current node table 125a shown in FIG. 10 and the current branch table 125b shown in FIG. 11 are expressed in a graph structure. In the distribution system diagrams shown in FIGS. 12 and 13, the node having the node ID “SS0001N01” is set to the root (one layer) of the hierarchical structure. Furthermore, in the distribution system diagrams shown in FIGS. 12 and 13, the facility IDs “LL000101”, “LL000201”, “LL000301”, “LL000401”, “LL000501”, “LL000601”, “LL000701”, “LL000701” The routes to the eight load facilities “LL000801” are shown. Among them, the hierarchy from the SS bank to the load equipment with the equipment ID “LL000801” is the shallowest with 10 hierarchies, and the hierarchy from the SS bank to the load equipment with the equipment IDs “LL000201”, “LL000301” and “LL000401” is 19 hierarchies. You can see the deepest. In addition, in the distribution system diagrams shown in FIGS. 12 and 13, the electrical connection of the distribution system is divided into equipment units and connection point units between equipments, not rough units such as high-voltage systems and low-voltage systems. Can be grasped.

  The display unit 118 can also generate an equipment map in which equipment such as units and spans are arranged on the map data 121 managed by the company. For example, when the equipment included in the current branch table 125b is a unit, the display unit 118 refers to the position information 122 and the equipment information 123 to acquire the equipment position of the unit. On the other hand, when the equipment included in the current branch table 125b is a span, the display unit 118 acquires the positions of both ends of the equipment in the span. In addition, the display unit 118 can output the display data of the facility map in which the unit and the span are arranged on the map data 121 by using the position of the unit and the positions of both ends of the span.

  FIG. 14 is a diagram illustrating an example of an equipment map. In the facility map shown in FIG. 14, the hierarchy from the SS bank to the load facility with the facility ID “LL000801” is the shallowest with 10 layers, as in the distribution system diagrams shown in FIGS. It can be understood that the hierarchy to the load facilities of “LL000201”, “LL000301”, and “LL000401” is the deepest with 19 hierarchies. As described above, in the facility map shown in FIG. 14, as in the distribution system diagrams shown in FIGS. 12 and 13, not the rough unit such as the high-voltage system and the low-voltage system, but the facility unit, and the connection point between the facilities. It is also possible to subdivide into units and grasp the electrical connection of the distribution system. In addition, in the facility map shown in FIG. 14, the display position of the unit and span corresponds to the position on the map data 121 managed by the company, so the repair and extension of the equipment such as the unit and span are planned. Easy to do. In addition, since it can be compared with geographical elements on the map data 121, for example, roads, railways and other infrastructure other than distribution system equipment, and landmarks, it is also useful when going to the site. .

  Returning to the description of FIG. 9, the external map acquisition unit 113 accesses the external geographic information system 40 via the communication I / F unit 100, and acquires the external map information 126 from the geographic information system 40 (S2). The external map acquisition unit 113 stores the acquired map information 126 in the storage unit 120.

  The map information 126 indicates the positions (for example, latitude and longitude) of various landmarks (including roads, schools, stations, and other facilities such as power plants (SS) managed by the company) provided by the geographic information system 40. It is the map data shown. This map information 126 is created based on aerial photographs and panoramic photographs of each point by traveling of a vehicle equipped with a GPS (Global Positioning System) for performing position measurement and an omnidirectional camera. The map information 126 includes information such as the shooting position in the image data and the position of the landmark included in the image data, as well as the image data of the aerial photograph and the panoramic photograph of each point.

  The extraction unit 114 refers to the storage unit 120 that stores the location information 122 of the facility associated with the map data 121, selects a plurality of facilities (nodes), and extracts the location of each facility (node) (S3). ). The extraction unit 114 stores the extracted plurality of facilities (nodes) in the storage unit 120 as the map information 126 of the node ID indicating each facility.

  Here, the details of the facility selection process for receiving selection of a plurality of facilities by the user of the client terminal 30 and extracting the selected facilities and outputting the map information 126 will be described. FIG. 15 is a flowchart illustrating the facility selection process.

  As illustrated in FIG. 15, when the process is started, the extraction unit 114 receives a plurality of facility selection instructions from the user of the client terminal 30 (S10). For example, in S10, by selecting a predetermined distribution system from the user on the screen on which the above-described distribution system diagram, facility map, etc. are displayed on the client terminal 30, a plurality of facilities that are electrically connected can be selected. Accept.

  Next, the extraction unit 114 searches the current node table 125a and the current branch table 125b for node IDs and position information (position IDs) corresponding to the selected plurality of facilities (nodes) (S11).

  Next, the extraction unit 114 starts the first loop processing (S12 to S23) for a plurality of facilities (nodes). When the first loop process is started, the extraction unit 114 first obtains information on the position, type, and other equipment associated with (electrically connected to) each equipment (second loop processing ( S13 to S17) are started.

  When the second loop process is started, the extraction unit 114 acquires equipment position information (latitude and longitude) from the location table 122a based on the equipment position ID (S14). Next, the extraction unit 114 acquires information (type and attribute information) of equipment at the position acquired with reference to the unit table 123a (S15). Next, the extraction unit 114 acquires information on equipment (branch, span) associated with the position acquired with reference to the span table 123b (S16).

  Following the second loop process, the extraction unit 114 determines whether the facility at the same position as the acquired facility is a high-pressure facility based on the information acquired in the second loop process (S18). . For example, if the extraction unit 114 is a facility tied to the high-voltage line WH, the extraction unit 114 is determined to be a high-pressure facility, and the determination is positive. Moreover, the extraction part 114 makes negative determination, when it is the equipment tied to the low voltage line WL.

  When a positive determination is made in S18 (S18: YES), the extraction unit 114 refers to the current node table 125a and the current branch table 125b, and selects a plurality of upstream facilities that are electrically connected starting from the facility at the same position. Extract. Specifically, the extraction unit 114 is a facility or SS bank (power station) that exists in an upstream facility that exists in a higher level, that is, downstream of an electrical connection and that exists in a range that reaches a higher voltage facility. ) Equipment existing in the range reaching () is extracted (S19).

  Next, the extraction unit 114 refers to the current node table 125a and the current branch table 125b, and extracts a plurality of downstream facilities that are electrically connected starting from the facility at the same position. Specifically, the extraction unit 114 extracts the downstream equipment existing in a higher level, that is, the equipment existing in the range reaching the lower voltage equipment that is downstream of the electrical connection (S20). . By this S19, S20, the extraction unit 114 is a high voltage section that is electrically connected, and a plurality of facilities in a section that exists at the same voltage level (for example, a section sandwiched between transformers). Extract.

  When a negative determination is made in S18 (S18: NO), the extraction unit 114 refers to the current node table 125a and the current branch table 125b, and selects a plurality of upstream facilities that are electrically connected starting from the facility at the same position. Extract. Specifically, the extraction unit 114 extracts equipment existing in a range reaching the upstream transformer (S21).

  Next, the extraction unit 114 refers to the current node table 125a and the current branch table 125b, and extracts a plurality of downstream facilities that are electrically connected starting from the facility at the same position. Specifically, the extraction unit 114 extracts facilities existing in a range reaching the downstream transformer (S22). By these S21 and S22, the extraction unit 114 is a low voltage section that is electrically connected, and a plurality of facilities in a section that exists at the same voltage level (for example, a section sandwiched between transformers). Extract.

  Following the first loop process described above, the extraction unit 114 outputs the node list 127 for the equipment extracted for each section by the processes of S19, S20 or S21, S22 (S24). Specifically, the extraction unit 114 outputs, for each section, a node list 127 that describes the node ID, position ID, type, and the like of equipment in the section.

  FIG. 16 is an explanatory diagram for explaining the node list 127. As illustrated in FIG. 16, the extraction unit 114 outputs the node list 127a for the equipment in the high voltage section from the substation (SS) to the predetermined transformer (fourth layer). Further, the extraction unit 114 outputs the node lists 127b and 127c for the equipment in the low voltage section from the transformer (fourth layer) until reaching the load. As described above, the extraction unit 114 outputs the node list 127 indicating the facilities included in the power distribution system for each predetermined power distribution system having an electrical connection such as a high voltage section and a low voltage section.

  Returning to the description of FIG. 9, the identifying unit 115 and the position changing unit 116 calculate the difference information 128 for matching the positions of the plurality of facilities in the node list 127 with the positions of the facilities in the external map information 126. Calculation processing is performed (S4). The node list 127 outputs the calculated difference information 128 and stores it in the storage unit 120 (S5).

  Specifically, the specifying unit 115 specifies the position of the facility corresponding to each of the plurality of facilities in the node list 127 from the external map information 126. Next, the position changing unit 116 manages the position of the facility in the external map information 126 and the company based on the position specified from the external map information 126 for each of the plurality of facilities in the specified node list 127. The distance from the facility position in the position information 122 is calculated. Next, the position changing unit 116 maps the position of each facility while maintaining the relative positional relationship of the plurality of facilities in the node list 127 based on the distance obtained for each of the plurality of facilities in the node list 127. Difference information 128 (for example, a numerical value to be added to or subtracted from latitude / longitude) to be changed to the position of the information 126 is calculated.

  Specifically, the position changing unit 116 assumes that the plurality of facilities in the node list 127 are on one integrated surface, and the difference information 128 is set so that the entire surface is slid to match the position of the facility in the map information 126. Is calculated. For example, in the example of FIG. 16, the difference information 128 is calculated for each distribution system of the node lists 127a, 127b, and 127c so that each of the node lists 127a, 127b, and 127c matches the position of the facility in the map information 126.

  In the facility management apparatus 1, by changing the position of the facility in the position information 122 based on the calculated difference information 128, there is no shift in the consistency of the positional relationship between the facilities, and the external map information 126 is updated with the location information of each facility. The position can be adjusted. In addition, by performing positioning for each distribution system of the node lists 127a, 127b, and 127c, the position to the external map information 126 without causing a shift in the consistency of the positional relationship of each facility included in the distribution system. Can be combined.

  Here, details of the distance calculation processing will be described. FIG. 17 is a flowchart illustrating the distance calculation process.

  As shown in FIG. 17, when the process is started, the identifying unit 115 searches for a substation (SS bank) from the location table 122a (S30). Next, the facility management apparatus 1 executes the first loop process (S31 to S48) for each substation (SS bank) searched.

  Specifically, the identifying unit 115 searches for surface data (node list 127) having its own SS bank (processing target substation (SS bank)) as a starting point or an ending point (S32). Next, the facility management apparatus 1 sets the searched surface data (node list 127) as a processing target (S33), and executes the second loop processing (S34 to S47). For the second loop processing, the plane data (node list 127) connected to the own SS bank is sequentially searched for processing. For example, in the example of FIG. 16, the node lists 127a to 127c are sequentially searched for processing.

  When the second loop process is started, the identifying unit 115 refers to the distribution system information 125 and selects the upper node (top node) by electrical connection in the processing target plane data (node list 127). (S35).

  Next, the specifying unit 115 refers to the position information 122 and acquires the latitude and longitude of each node (facility) included in the node list 127 to be processed (S36). Next, the specifying unit 115 specifies the position of each facility included in the external map information 126 from the latitude and longitude of each node (facility) acquired from the position information 122 (S37).

  Specifically, the specifying unit 115 searches for landmarks in the map information 126 in the vicinity of the latitude and longitude of each node (equipment) acquired from the position information 122 (for example, within a range of several meters to several tens of meters). Next, when the type of the searched landmark matches the type of each node (equipment) in the unit table 123a, the specifying unit 115 specifies that the searched landmark corresponds to each node (equipment). Then, the position (for example, latitude and longitude) of the landmark is acquired from the map information 126.

  Note that each node (equipment) is included in the aerial photograph or the panoramic photograph of each point in the map information 126, but there are facilities that are not registered as landmarks on the map. Therefore, when there is no searched landmark corresponding to each node (equipment), the distribution system information 125 is obtained by image recognition of image data of aerial photographs and panoramic photographs of each point included in the map information 126. The position corresponding to each node (equipment) is specified.

  Specifically, the specifying unit 115 refers to the aerial photograph and the panoramic photograph image data included in the map information 126 and captures the latitude and longitude of each node (equipment) acquired from the position information 122. Identify image data. Next, the identification unit 115 applies a known image recognition technique to the identified image data, thereby classifying each node (equipment) in the unit table 123a (for example, power plant (SS), utility pole P, switch SW, transformer). The object corresponding to the shape of the instrument TR etc. is detected. Next, the identifying unit 115 identifies the detected subject as corresponding to each node (equipment), and based on the shooting position of the image and the position of the subject in the image, the position of the subject (facility) ( For example, latitude and longitude) are specified.

  Next, the position changing unit 116 obtains a difference (for example, a difference between latitude and longitude) between the position of the top node acquired from the position information 122 and the position specified from the map information 126 corresponding to the top node. Next, the position changing unit 116 shifts the positions of the entire nodes (equipment) included in the processing target node list 127 according to the obtained difference, and difference information for adjusting the position of the top node to the position of the corresponding map information 126. 128 is generated (S38).

  Next, the position changing unit 116 executes a third loop process (S39 to S46) for each node other than the top node included in the node list 127 to be processed.

  When the third loop process is started, the position changing unit 116, like the top node, the position of the processing target node acquired from the position information 122 and the position specified from the map information 126 corresponding to the node. The difference information 128 is generated on the basis of the difference. Next, the position changing unit 116 compares the position of each node (equipment) included in the map information 126 with the latitude and longitude of each node changed by the generated difference information 128 (S40). That is, the position changing unit 116 obtains the difference (deviation) between the node position in the map information 126 and the changed node position based on the difference information 128 for each node included in the node list 127.

  Next, the position changing unit 116 determines whether or not the sum of deviations obtained in the current loop process is smaller than the sum of deviations obtained in the previous loop process (S41). If small (S41: YES), the position changing unit 116 updates the difference information 128 using the difference information 128 generated in the current loop process as data that minimizes the positional deviation from the map information 126 (S42). In the facility management apparatus 1, the position information 122 is changed on the map information 126 so that the positional deviation of each node (facility) is minimized by changing the position information 122 using the difference information 128. Can be adjusted to the position.

  Next, the specifying unit 115 determines whether the other node electrically connected to the processing target node is other than a blank based on the current branch table 125b (S43). For example, if the connection destination of the processing target node in the current branch table 125b is blank (blank), the specifying unit 115 determines that the other node is blank. If it is blank (S43: NO), the identifying unit 115 advances the process to S46.

  When it is other than a blank (S43: YES), the specifying unit 115 refers to the open / close section of the current branch table 125b and determines whether the open / close state for the other node is ON (S44). When the open / close state is not ON (S44: NO), the identifying unit 115 advances the process to S46.

  When the open / close state is ON (S44: YES), the specifying unit 115 adds the other searched node to the node list 127 and advances the process to S46.

  The display unit 118 applies the difference information 128 to the position information 122 in the map data 121 managed by the company, and changes the position of each facility such as a unit and a span managed by the company. Then, the display unit 118 outputs display data for displaying the changed position information to the client terminal 30 or the like.

  For example, when displaying the equipment map in accordance with the external map information 126 on the client terminal 30, the display unit 118 applies the difference information 128 to the position information 122 to change the position of each equipment such as a unit and a span. . And the display part 118 outputs the display data of the equipment map which has arrange | positioned each equipment on the map by the map information 126 based on the position of each equipment changed.

  FIG. 18 is an explanatory diagram for explaining the display of equipment using the difference information 128. Note that an upper street view screen G in FIG. 18 is a street view screen when an equipment map based on the map information 126 is displayed without applying the difference information 128 to the position information 122 of the map data 121. Further, the lower street view screen G in FIG. 18 is based on the map information 126 after applying the difference information 128 to the position information 122 of the map data 121 to change the position of each unit such as a unit and span managed by the company. It is a street view screen at the time of displaying an equipment map.

  As shown in FIG. 18, in the street view screen G in which the difference information 128 is not applied to the position information 122 of the map data 121, the display position G1 of the equipment (electric pole in the illustrated example) taken in the panoramic photograph of the map information 126; The display position G2 based on the position information 122 does not match, and a positional shift has occurred. On the other hand, on the street view screen G in which the difference information 128 is applied to the position information 122 of the map data 121, the display position G1 of the equipment (electric pole in the illustrated example) captured in the panoramic photograph of the map information 126, and the position information 122 Is coincident with the display position G2.

  As described above, in the street view screen G based on the map information 126, it is possible to make it easy to check the position of the equipment when performing maintenance of the equipment, for example, by preventing the equipment from being displaced.

The The facility management program 270a may be appropriately integrated or separated as with each component such as the extraction unit 114, the identification unit 115, the position change unit 116, or the output unit 117 illustrated in FIG. That is, not all data stored in the HDD 270 is always stored in the HDD 270, but data related to processing may be stored in the HDD 270.

  Then, the CPU 250 reads the facility management program 270a from the HDD 270 and expands it in the RAM 280. Thereby, as shown in FIG. 19, the facility management program 270a functions as a facility management process 280a. The facility management process 280a expands various data read from the HDD 270 in an area allocated to itself on the RAM 280 as appropriate, and executes various processes based on the expanded data. The facility management process 280a includes processing executed by the extraction unit 114, the identification unit 115, the position change unit 116, the output unit 117, and the like illustrated in FIG. In addition, as for each processing unit virtually realized on the CPU 250, not all processing units always operate on the CPU 250, but a processing unit related to processing may be virtually realized.

  The facility management program 270a may not be stored in the HDD 270 or the ROM 260 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk inserted into the computer 200, so-called FD, CD-ROM, DVD disk, magneto-optical disk, or IC card. Then, the computer 200 may acquire and execute each program from these portable physical media. Each program is stored in another computer or server device connected to the computer 200 via a public line, the Internet, a LAN, a WAN, etc., and the computer 200 acquires and executes each program from these. It may be.
