JP7424006B2 - Fallen tree monitoring device and program - Google Patents

Description

The present invention relates to a fallen tree monitoring device and program.

Ground faults can occur due to falling trees coming into contact with power lines. If a ground fault occurs, the section where the ground fault occurred will be separated from the electrical circuit using a relay or the like for safety. Therefore, power outages may occur in areas where ground faults occur. Therefore, in order to prevent fallen trees from coming into contact with power lines, trees near power lines are systematically cut down. Therefore, a device for predicting the time to cut down trees has been proposed (see, for example, Patent Documents 1 and 2).

Japanese Patent Application Publication No. 2008-3855 JP2006-252310A

In the devices described in Patent Documents 1 and 2, the growth of trees is predicted to predict the timing (cutting timing) that will affect equipment. The devices of Patent Documents 1 and 2 are useful in that they can cut down trees in a planned manner. On the other hand, in recent years, due to torrential rains and an increase in the number of typhoons approaching, the number of unexpected trees falling has increased. Since such unexpected fallen trees are not expected, it may take some time to discover them. Further, a telephone or the like is generally used to report the discovery of a fallen tree from a third party to an electric power company or the like. As a result, people sometimes avoid reporting due to the hassle of telephone contact. Therefore, it would be preferable if a device could be realized that allows for simpler notification and also enables identification of the position of a fallen tree in response to a simple notification. For example, it would be preferable to implement a device that can specify the location of a fallen tree in response to a simple one-button push notification using an application on a mobile terminal.

Hereinafter, a fallen tree monitoring device 1 and a program according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.
First, the electric wire L monitored by the fallen tree monitoring device 1 according to the present embodiment will be described.

The electric wire L is, for example, a power transmission line installed in the mountains or a power distribution line installed in the city. In this embodiment, the fallen tree monitoring device 1 monitors power transmission lines in the mountains, for example. Since the electric wire L is disposed between trees, there is a possibility that it may come into contact with a fallen tree T or the like. When the electric wire L comes into contact with a fallen tree T or the like, a predetermined section including the ground fault point is separated from other sections using a ground fault relay or the like. As a result, the separated section becomes in a power outage state.

Next, a fallen tree monitoring system 100 including the fallen tree monitoring device 1 according to the present embodiment will be described.
The fallen tree monitoring system 100 receives a report from a discoverer (for example, a third party M) who has discovered a fallen tree T through a mobile terminal 2 owned by the third party M. The fallen tree monitoring system 100 specifies the position of a fallen tree by flying the flying object 3 and monitoring the section specified based on the report. The fallen tree monitoring system 100 includes a mobile terminal 2, a flying object 3, and a fallen tree monitoring device 1, as shown in FIG.

The mobile terminal 2 is, for example, a mobile phone (smartphone) owned by a third party M. The mobile terminal 2 includes a fallen tree information output section 21, as shown in FIG.
The fallen tree information output unit 21 is realized by, for example, operating a CPU. The fallen tree information output unit 21 outputs the position of the mobile terminal 2 and the notification of the occurrence of the fallen tree T as fallen tree information. The fallen tree information output unit 21 outputs fallen tree information based on, for example, pressing of a report button (not shown) displayed together with the map in an application that displays a map of the power outage location.

The flying object 3 is, for example, a drone or a remotely controlled unmanned aircraft (helicopter). The flying object 3 is configured to be able to fly along a predetermined route based on remote control. The flying object 3 includes an imaging section 31, a position measurement section 32, and an image transmission section 33.

The imaging unit 31 is, for example, a camera that captures moving images. The imaging unit 31 captures images (moving images) along the flight route of the flying object 3. That is, the imaging unit 31 captures an image (moving image) along the line of the electric wire L.

The position measurement unit 32 is realized, for example, by the operation of a CPU. The position measurement unit 32 measures the flight position of the flying object 3. The position measurement unit 32 measures the flight position using, for example, a GPS (Global Positioning System) signal.

The fallen tree information acquisition unit 11 acquires fallen tree information via, for example, a general communication line.

The wire information storage unit 12 is, for example, a secondary recording medium such as a hard disk. The electric wire information storage unit 12 stores electric wire information indicating the arrangement position (for example, latitude and longitude) and arrangement height of the electric wire L.

The monitoring section determining unit 13 is realized, for example, by the operation of a CPU. The monitoring section determination unit 13 determines the section of the electric wire L to be monitored by the flying object 3 based on the position of the mobile terminal 2 included in the acquired fallen tree information. For example, as shown in FIG. 3, the monitoring section determining unit 13 determines a section of the electric wire L that is visible from the position of the mobile terminal 2 as a monitoring section to be monitored by the flying object 3. The monitoring section determining unit 13 determines, as the visible electric wire L, a section of the electric wire L that is included in an area that is generally visible from the position of the mobile terminal 2 as the monitoring section. The monitoring section determining unit 13 determines, for example, a section of the electric wire L included in a region R having a visible radius centered on the position of the mobile terminal 2 as the monitoring section. Furthermore, the monitoring section determination unit 13 determines the flight altitude at which the aircraft flies in the monitoring section, depending on the height of the electric wire L.

The flight control unit 14 is realized by, for example, operating a CPU. The flight control unit 14 causes the flying object 3 to fly over the determined monitoring section and capture an image of the vicinity of the electric wire L. For example, the flight control unit 14 remotely controls the flying object 3 to cause it to fly over the determined monitoring section. The flight control unit 14 causes the flying object 3 to take an image of the situation around the electric wire L by flying the flying object 3 along the electric wire L at the altitude determined in the monitoring section. That is, the flight control unit 14 causes the flying object 3 to take an image of the reported situation of the fallen tree T.

The image output unit 17 is realized by, for example, operating a CPU. The image output unit 17 outputs the acquired captured image. The image output unit 17 outputs the captured image to a display device (not shown) in a displayable manner, for example.

The felling determination unit 18 is realized, for example, by the operation of a CPU. The felling determination unit 18 determines whether or not felling is necessary based on the condition of the fallen tree T included in the acquired captured image. The felling determination unit 18 detects, for example, a fallen tree T included in the captured image. The felling determining unit 18 determines that a fallen tree T is present, for example, when the position of the electric wire L included in the captured image and the position of the fallen tree T are in contact with each other. Furthermore, when it is determined that there is a fallen tree T, the felling determination unit 18 determines that felling is necessary. Further, the felling determination unit 18 identifies the felling position based on the imaging position of the captured image.

The felling instruction output unit 19 is realized, for example, by the operation of a CPU. The felling instruction output unit 19 outputs an instruction to cut down the fallen tree T. Further, the felling output unit outputs an instruction including the cutting position. The felling output unit outputs an instruction including the felling position specified by the felling determination unit 18, for example, when the felling determination unit 18 determines that felling is necessary. The felling instruction output unit 19 outputs an instruction by, for example, displaying the cutting position as a plot on a display device together with a map including the cutting position.

Next, the operation of the fallen tree monitoring device 1 will be explained with reference to FIG. 4.
First, it is determined whether the fallen tree information acquisition unit 11 has acquired fallen tree information (step S1). When the fallen tree information acquisition unit 11 acquires the fallen tree information from the mobile terminal 2 (step S1: YES), the process proceeds to step S2. On the other hand, if the fallen tree information acquisition unit 11 has not acquired the fallen tree information from the mobile terminal 2 (step S1: NO), the process repeats step S1.

In step S2, the monitoring section determination unit 13 determines the section of the electric wire L to be monitored by the flying object 3. Specifically, the monitoring section determination unit 13 determines the section of the electric wire L to be monitored by the flying object 3 based on the position of the mobile terminal 2 included in the acquired fallen tree information.

Next, the flight control unit 14 causes the flying object 3 to start flying (step S3). The flight control unit 14 causes the flying object 3 to fly in the determined monitoring section. The flight control unit 14 also captures an image of the monitoring section.

Next, the image acquisition unit 15 acquires a captured image and an imaging position from the flying object 3 (step S4). The image acquisition unit 15 stores the acquired captured image and imaging position in the image storage unit 16.

Next, the image output unit 17 outputs the captured image stored in the image storage unit 16 (step S5). The image output unit 17 outputs the captured image to a display device, for example. Further, the image output unit 17 outputs the imaging position to a display device.

Next, the felling determining unit 18 detects a fallen tree T, and determines whether or not the detected fallen tree T needs to be felled (step S6). If the felling determination unit 18 determines that felling is necessary (step S6: YES), the process proceeds to step S7. On the other hand, if the tree felling determination unit 18 determines that tree felling is unnecessary (step S6: NO), the process according to this flow ends.

In step S7, the felling instruction output unit 19 outputs an instruction including the cutting position. The felling instruction output unit 19 outputs, for example, an instruction including a felling position to a display device. Thereby, the processing according to this flow ends.

Therefore, an increase in the number of reports from third party M can be expected. Furthermore, even with a simpler report, the location of a fallen tree can be easily identified.

(2) The monitoring section determination unit 13 determines the section of the electric wire L that is visible from the position of the mobile terminal 2 as the monitoring section to be monitored by the flying object 3. Thereby, an effective monitoring section can be determined according to the position of the mobile terminal 2. Therefore, even if it is a simple notification, the position of a fallen tree can be effectively monitored.

For example, in the embodiment described above, the fallen tree information acquisition unit 11 may also acquire the direction of the mobile terminal 2 by including it in the fallen tree information. It is considered that the third party M often makes a report while looking in the direction of the fallen tree T. Therefore, by including the direction of the mobile terminal 2 in the fallen tree information and acquiring it, it is possible to predict the position of the fallen tree T existing in the direction acquired from the position of the mobile terminal 2. The monitoring section determination unit 13 determines the monitoring section from the position of the mobile terminal 2 and the acquired direction. Thereby, fallen trees T can be monitored more efficiently.

Further, in the embodiment described above, the tree felling determining unit 18 determines that tree felling is necessary when the fallen tree T is in contact with the electric wire L, but the present invention is not limited to this. The felling determination unit 18 may determine that a fallen tree T that is close to the electric wire L by a predetermined distance or more needs to be felled.
