Description

  Embodiments described herein relate generally to a theft detection support device, a theft detection support method, and a program that contribute to prevention of unauthorized use of power.

  Unauthorized use of power (hereinafter collectively referred to as stealing) is a problem particularly in emerging countries. The theft rate in Japan is almost 0%, but this is rare in the world, and there are countries where the theft rate exceeds 30%. Stealing electricity can last for decades unless something happens.

  Electrical resistance generated in system facilities such as transformers, circuit breakers, and transmission / distribution lines is a loss for distribution companies. This loss increases as the amount of power stolen increases. Due to theft of electricity, distribution companies are also incurred this technical loss and financial loss due to the failure to collect electricity charges, which in turn burdens good customers. It would be desirable to be able to discover without overlooking theft.

  There is known a technology capable of monitoring from a pole transformer to a high voltage cable section of 6.6 kilovolts [kV] on the backbone network side. However, with existing technology, it is difficult to detect power theft in a portion closer to the customer, that is, a power distribution portion from the utility pole to the customer. If a bypass line that is not a legitimate service line is installed in this part and the power meter is bypassed, it is difficult to detect this type of theft.

  For example, a technique is known in which a bypass line detection circuit is provided in a part of a power supply and demand meter and the presence or absence of a bypass line in a distribution part is determined based on a test current. However, this technology is very inconvenient because the customer powers out during the test. There is a need for a technique that can reliably detect bypass in the end section of the power distribution network without causing power outages to consumers.

  An object is to provide a theft detection support device, a theft detection support method, and a program for supporting reliable detection of theft.

  According to the embodiment, the theft detection support device includes a storage unit, an extraction unit, a specifying unit, and a display unit. A memory | storage part memorize | stores the image data containing the street view in the object area, and the separate electric power contract information of the electric power supplier and a consumer. The extraction unit extracts a power lead-in line from the image data. The specifying unit specifies a power receiving point for each consumer based on the door-to-door power contract information. The display unit displays the extracted lead-in line and the identified power receiving point on the digital map of the area.

FIG. 7 is a diagram showing an example of a digital map that highlights the determined unauthorized lead-in line.

  FIG. 1 is a functional block diagram illustrating an example of a theft detection support apparatus according to the embodiment. The theft detection support device 100 according to the embodiment is realized by installing a theft detection program on a general-purpose computer, for example. The theft detection support device 100 includes a display 10, a storage unit 20, an input / output unit 30, a CPU 40, and a program memory 50.

  The display 10 is a user interface that visually displays various types of information. The display 10 forms a GUI (Graphical User Interface) environment in combination with an input / output unit 30 including a mouse and a keyboard.

The storage unit 20 is a semiconductor memory such as a random access memory (RAM) or a read only memory (ROM), or a hard disk drive (HDD). The storage unit 20 stores image data 20a, map data 20b, door-to-door power contract information 20c, and real estate registration information 20d.
The image data 20a is data obtained by photographing an area to be subjected to theft detection, and includes a street view of the area. This type of data can be acquired by, for example, a probe car equipped with an imaging device. That is, the image data 20a can be created by taking a landscape image along the road while running the probe car.

  In many cases, the image data 20a is provided by being recorded on a medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a Blu-ray (registered trademark) disc. The storage unit 20 reads the image data 20a from these media and stores it.

FIG. 2 is a diagram illustrating an example of a street view. FIG. 2 shows an example of image data acquired by the probe car. This image data can be displayed on the display 10. It can be seen that the landscape image (image data) includes buildings along the road, utility poles, transformers on poles, electric wires, and service lines. In addition, the field of view of the photographing apparatus includes vehicles on the road, roadside trees, and the like.
In particular, in the embodiment, the image data 20a includes position information (latitude information, longitude information, etc.) of the utility pole included in the street view. By embedding the position information of the utility pole as metadata, for example, in the image data 20a, it is possible to include the position information of the utility pole in the image data 20a. The position information can be acquired by a positioning system such as GPS (Global Positioning System).

  The position information of the utility pole can be recorded individually by surveying, for example. Alternatively, it is also possible to associate the position information of the probe car when photographing the utility pole with the location information of the utility pole. As shown in FIG. 2, it is also possible to indicate the position of the probe car that captured the view by a small window displayed in a superimposed manner on the street view.

Returning to FIG. 1, the map data 20b is map data of the area in which the image data 20a is created. For example, a digital map from a viewpoint overlooking an area corresponds to the map data 20b.
The door-to-door power contract information 20c is information in which a contract made by a power supplier (electric power company) and a customer is recorded in a data format. For example, by requesting an electric power company and recording it on a medium such as a CD-ROM, it is possible to acquire the door-to-door power contract information 20c. In the door-to-door power contract information 20c, at least an address of a building that receives power supply is registered.
The real estate registration information 20d is real estate registration information in an area targeted for detection of theft. This kind of data can also be obtained, for example, if requested by the local government.

  Next, the program memory 50 stores an extraction program 50a, a specific program 50b, a display control program 50c, a verification program 50d, and a detection program 50e as programs including instructions necessary for processing functions according to this embodiment. . These programs can be recorded on a removable medium (recording medium) such as a CD-ROM, or can be downloaded via a communication line.

  The CPU 40 reads each program from the program memory 50 and performs arithmetic processing by hardware, and includes an extraction unit 40a, a specifying unit 40b, a display control unit 40c, a collation unit 40d, and a detection unit 40e as its processing functions.

  The extraction unit 40a performs image processing on the image data 20a and extracts a power lead-in line from the image data 20a. For example, it is possible to extract a drawn line from the image data 20a by extracting a set of consecutive points of a specific color (such as black) from a three-dimensional image as a line or recognizing a branch of the line. Easily possible.

  The specifying unit 40b specifies a power receiving point for each power consumer based on the door-to-door power contract information 20c. The power receiving point may be, for example, an attachment position of a watt-hour meter (including a smart meter) or a position of a demarcation point between a power company and a customer.

  The display control unit 40c displays the lead-in line extracted by the extraction unit 40a and the power receiving point specified by the specifying unit 40b on the display 10 so as to overlap the digital map of the target area. In particular, the display control unit 40c displays the utility pole included in the image data 20a on a digital map based on the position information.

  The collating unit 40d collates the lead-in line extracted by the extracting unit 40a with the power receiving point specified by the specifying unit 40b. That is, the collation unit 40d confirms whether or not the lead-in line and the power receiving point have a one-to-one correspondence by collating each other's position on the digital map.

  The detection unit 40e detects a lead-in line that does not correspond to the power receiving point based on the result of the collation by the collation unit 40d. That is, the detection unit 40e detects a lead-in line that is extended to a position where there is no power receiving point. There is a high possibility that the detected lead-in wire is illegally used due to power theft, but it cannot be said that it is certainly illegally used.

  Therefore, the detection unit 40e determines a service line to be laid in the registered building among the detected service lines based on the real estate registration information 20d. In other words, it is understood that the service lines connected to the buildings that are not registered are not used for reasons such as the absence of residents, and the ones that have been installed by past contracts remain. On the other hand, it is possible to consider that the lead-in wire connected to the registered building even though there is no power receiving point is illegally used.

  In this way, the accuracy of the information is increased based on the real estate registration information 20d, and the detection unit 40e notifies the display control unit 40c of the detected lead-in line. The display control unit 40c highlights the lead-in line determined by the detection unit 40e as being illegally used on the digital map. The highlight display has various modes such as color coding, blinking, line type distinction, line thickness distinction, or arrow indication. Next, the operation of the above configuration will be described.

  FIG. 3 is a flowchart illustrating an example of a processing procedure of the theft detection support apparatus according to the embodiment. The theft detection support device extracts a lead-in line from the image data 20a (step S1). For example, as shown in FIG. 4, the extracted lead-in lines are displayed on a digital map displayed on the display 10 together with symbols indicating utility poles and electric wires (including lead-in lines). Thereby, the laying situation of the electric wire and the utility pole in the target area is understood. The accuracy of the display position can be improved by displaying the utility pole on the digital map based on the position information.

  Next, the power theft detection support apparatus specifies a power receiving point for each customer based on the door-to-door power contract information 20c (step S2). The identified power receiving point is displayed as an icon (◯ ×) as shown in FIG. 5, for example. The icon shown in FIG. 5 corresponds to a power receiving point of a customer with a contract.

  Next, the theft detection support apparatus superimposes the image layer shown in FIG. 4 and the image layer shown in FIG. 5 to generate digital map data shown in FIG. The display control unit 40c displays a digital map including a lead-in line and a power receiving point on the display 10 (step S3).

  Next, the theft detection support device collates the extracted lead-in line with the identified power receiving point (step S4). As a result of the collation, if a lead-in line that does not correspond to the door-to-door power contract is detected (Yes in step S5), the theft detection support device displays this lead-in line separately from the others. On the map of FIG. 6, the detected lead-in line is indicated by a solid line.

  Next, the theft detection support device refers to the real estate registration information 20d and verifies whether or not the building where the service line is laid is registered (step S7). If Yes in step S7, a lead-in line is found that is laid in a building that has been registered but has no power receiving point. Accordingly, the theft detection support device highlights the lead-in line on the digital map displayed on the display 10 as shown in FIG. 7 (step S8).

  For example, in FIG. 7, among the three service lines leading to the building A, the center service line has no corresponding power receiving point. However, the portion (room or tenant) at the position of the power receiving point is not registered, and therefore is not considered illegal. On the other hand, since building B is registered, it is considered that there is unauthorized use of power.

  The unauthorized lead-in line determined in the above procedure is stored in the storage unit 20 (step S9). That is, the theft detection support apparatus accumulates the history of unauthorized service lines. The procedure shown in FIG. 3 can be executed every time the image data 20a acquired by the probe car is updated.

  That is, every time the image data 20a is updated, the theft detection support device determines an unauthorized service line, that is, a service line installed in a registered building without a power receiving point, and accumulates the history. Then, based on this history, the theft detection support device displays the determined history of the unauthorized lead-in line on the display 10 in time series.

  As described above, in the embodiment, the power lead-in line is extracted from the image data 20 a including the street view acquired by the probe car and displayed on the display 10. Further, the power receiving point for each customer is specified from the door-to-door power contract information 20c, and this is also displayed on the display 10. As a result, it becomes possible to visually compare the actual electric wire laying status and the power contract information, and it is possible to easily detect the laid electric wires (lead wires) not in the contract.

  In the embodiment, the service line that is not in the contract is collated with the real estate registration information 20d, and the service line that is laid in the building where the property is registered is determined from the service lines that are not in the contract. As a result, it is possible to identify a building that is almost surely stolen, and it is possible to visualize, that is, visualize, the detected stolen location by highlighting an unauthorized lead-in line. Furthermore, by regularly collating the update information of the image data 20a and the detection result of theft, it is possible to detect a lead-in wire laid out of plan.

  In the existing technology, the test current from the power source built in the watt hour meter is detected by the built-in current transformer to determine the presence or absence of the bypass line. Cannot be detected. On the other hand, in the embodiment, since it is possible to determine whether there is power theft based on the image data, it is not necessary to power out the customer, and it is not necessary to notify the customer, so fraud is concealed. Can also be prevented.

  In addition, the theft detection support apparatus according to the embodiment can cope with a demand for roughly grasping the theft situation in the target area. That is, the conventional method of confirming the presence or absence of power theft for each case costs a huge amount of cost. On the other hand, in the embodiment, if image data obtained by photographing the target area is facilitated, it is possible to detect theft by image processing, so that the cost can be reduced. As a result, it is possible to meet the need to focus on areas where there is a lot of theft, and to detect them in consideration of cost effectiveness.

  Furthermore, the theft detection support device according to the embodiment can be used in combination with a smart meter. As is well known, a smart meter is a device used in a next-generation power network, and can grasp the power usage status of each consumer in almost real time. Using this function, it is possible to apply an application in which an area with a low fee collected with respect to power demand is stared and theft is detected by obtaining image data of that area. Therefore, it is possible to provide a theft detection support device, a theft detection support method, and a program that support the reliable detection of theft.

The present invention is not limited to the above embodiment. For example, in the embodiment, the presence or absence of theft is determined by the theft detection support device, and an unauthorized lead-in line is specified. Instead of this, it is also possible to leave the subsequent determination to a human by simply displaying the lead-in line and the power receiving point. In other words, extraction of service lines, identification of power reception points, and display of these on the digital map are processed by a theft detection support device, matching between service lines and power reception points, identification of unauthorized service lines, real estate information The matching may be performed by a human. Thus, the object can also be achieved by letting the apparatus process only the visualization of information.
Furthermore, if the history of past house-to-house power contract information owned by the power company can be obtained, it becomes possible to carry out a more precise power theft determination by combining with the history of image data.

  Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
