Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Further, not all of the combinations of features described in the embodiments are essential to the solving means of the invention.

FIG. 1 schematically illustrates a usage pattern of a system 100 according to an embodiment. The system 100 is a system for presenting to the worker 80 the arrangement of electric wires in a live state arranged in the factory 50 in which the worker 80 works. The system 100 includes a server 130 and a worker terminal 140.

The worker 80 is, for example, a person who works in the factory 50. For example, the worker 80 is a worker who inspects the device M1 and the device M2. The worker terminal 140 is a terminal used by the worker 80. The worker terminal 140 is, for example, a mobile terminal. Examples of the mobile terminal include a mobile phone, a smartphone, a tablet, a PDA, a notebook computer, a laptop computer, a wearable computer and the like. The worker terminal 140 may be a general-purpose computer such as a personal computer. The worker terminal 140 communicates with the server 130 via the network 110. The worker 80 is an example of a user, and the worker terminal 140 is an example of a user terminal.

Electric power is drawn into the factory 50 through an electric wire L0 which is a lead wire from the electric pole 60 to the factory 50. The electric power drawn through the electric wire L0 is supplied to the electric power load in the factory 50 through the switchboard 70, the electric wire L10, and the distribution board 72. The switchboard 70 drops the high voltage supplied through the electric wire L0 to the low voltage used in the factory 50. The distribution board 72 receives the low-voltage power from the distribution board 70, and distributes the power to electrical devices such as the lighting device D11 and the lighting device D12, the machine M1, and the machine M2.

A sensor 90 that detects the voltage of the electric wire L0 connected to the power supply side is provided in the switchboard 70. The sensor 90 transmits the detected voltage information to the server 130 via the network 110. The switchboard 70 includes a transformer that converts received high-voltage power into low-voltage power, a disconnector, and a circuit breaker. The switchboard 70 transmits the open/closed states of the disconnector and the circuit breaker to the server 130 via the network 110. The distribution board 72 transmits the open/closed state of a disconnector included in the distribution board 72 to the server 130 via the network 110.

When performing the work in the factory 50, the worker 80 uses the worker terminal 140 to confirm the arrangement of the live wires in the factory 50. For example, the worker terminal 140 starts the imaging operation by the camera function of the worker terminal 140 when the worker 80 starts the hot line confirmation application installed in the worker terminal 140. The worker terminal 140 transmits the image information including the captured image data and the image capturing condition including the image capturing direction, the image capturing position, and the angle of view of the worker terminal 140 to the server 130 to provide the hot line arrangement. To request.

The server 130 acquires the wiring model information of the factory 50 associated with the imaging position included in the image information received from the worker terminal 140. The server 130 is associated with the energization information of the electric wire L0 detected by the sensor 90 associated with the factory 50, the open/closed states of the disconnector and the circuit breaker of the switchboard 70 associated with the factory 50, and the factory 50. The wiring in the hot line state is specified based on the open/closed state of the circuit breaker of the distribution board 72 and the wiring model information.

For example, when the voltage detected by the voltage sensor 90 is higher than a predetermined voltage and the disconnector and the circuit breaker of the switchboard 70 are in the closed state, the server 130 uses the electric wire of the circuit breaker included in the distribution board 72. When only the circuit breaker connected to L11 is in the closed state, the wires L0, L10, L11 and L111 are specified as the wires in the live state, and the wires L12 and L13 are set as the wires not in the live state. Identify. The server 130 generates a wiring superimposed image in which the three-dimensional arrangement of the electric wire L10, the electric wire L11, and the electric wire L111 that are in a live state is superimposed on the image included in the image information, and transmits the wiring superimposed image to the worker terminal 140. The worker terminal 140 displays the wiring superimposed image acquired from the server 130.

FIG. 2 schematically shows an example of the wiring superimposed image 200 displayed on the worker terminal 140. The server 130 has an object 210 showing the arrangement of the electric wire L0, an object 220 showing the electric wire L10, an object 230 showing the arrangement of the electric wire L11, an object 240 showing the arrangement of the electric wire L12, and an object 250 showing the arrangement of the electric wire L13. Are superimposed on the image 290 captured by the worker terminal 140 to generate the wiring superimposed image 200.

When the electric wire L0, the electric wire L10, and the electric wire L11 are specified as the electric wires in a live state among the electric wires L captured in the image 290, the server 130 sets the object 210, the object 220, and the object 230 as the object 240, The object 250 is emphasized. Thereby, the worker 80 can easily recognize the arrangement of the electric wires in a live state by looking at the wiring superimposed image 200. Therefore, it is possible to reduce the possibility that the worker 80 touches the live line during the work.

FIG. 3 shows an example of a block configuration of the server 130. The server 130 includes a processing unit 300 and a storage unit 380. The processing unit 300 includes a wiring information acquisition unit 310, an energization information acquisition unit 320, an identification unit 330, a control unit 340, and an image information acquisition unit 350. The processing unit 300 is realized by a general-purpose processor, a communication processor, or the like.

The storage unit 380 is realized by a non-volatile storage device. The storage unit 380 acquires the information detected by the voltage sensor 90 from the voltage sensor 90 and stores it. The storage unit 380 acquires the opening/closing information of each of the disconnector and the circuit breaker included in the switchboard 70 from the switchboard 70 and stores the information. The storage unit 380 acquires the opening/closing information of each circuit breaker included in the distribution board 72 from the distribution board 72 and stores it. Further, the respective power supply states of the machine M1 and the machine M2 are acquired from the machine M1 and the machine M2 and stored.

In the processing unit 300, the wiring information acquisition unit 310 acquires wiring information indicating the three-dimensional arrangement of the electric wires L provided in a predetermined space. The energization information acquisition unit 320 acquires at least one of information indicating the energization state of the electric wire L detected by the sensor 90 and information indicating the states of the switchboard 70 and the distribution board 72 to which the electric wire L is connected. The identifying unit 330 identifies the electric wire L that is in a live state based on the information acquired by the energization information acquiring unit 320. The control unit 340 causes the worker terminal 140 used by the worker 80 to display the three-dimensional arrangement of the electric wires L in a live state based on the wiring information.

The distribution board 70 and the distribution board 72 are examples of distribution equipment. The distribution equipment may be at least one of a distribution board and a distribution board.

The energization information acquisition unit 320 acquires information detected by the sensor 90 and information indicating the states of the switchboard 70 and the distribution board 72. The information indicating the states of the distribution board 70 and the distribution board 72 may indicate the open/closed state of the circuit breaker included in at least one of the distribution board 70 and the distribution board 72.

The energization information acquisition unit 320 may further acquire information indicating a power state of an electric device that operates with the electric power supplied through the electric wire L. The lighting devices D1 and D2, the machine M1, and the machine M2 according to the present embodiment are examples of electric devices.

The control unit 340 may cause the worker terminal 140 to display the three-dimensional arrangement of the electric wires L in the live state in a mode different from the display mode of the three-dimensional arrangement of the electric wires L in the non-live state. For example, the control unit 340 may cause the worker terminal 140 to display the three-dimensional arrangement of the electric wires L that are in the live wire state in a color different from the color that displays the three-dimensional arrangement of the electric wires L that are not in the live wire state. .. The control unit 340 may display the three-dimensional arrangement of the electric wires L in a live state on the operator terminal 140 by emphasizing the three-dimensional arrangement of the electric wires L not in a live state.

The control unit 340 further sets the first position and the second position in the energized state to the load side of the first position which is not energized in the wiring path formed including the electric wire L. The worker terminal 140 may display the three-dimensional arrangement of the electric wires L between the two positions. For example, the control unit 340 displays the three-dimensional arrangement of the electric wires L between the first position and the second position in a mode different from the display mode of the three-dimensional arrangement of the electric wires L in the live state. It may be displayed on the terminal 140.

The control unit 340 may superimpose and display the three-dimensional arrangement of the electric wires L in the live line state on the image captured by the worker terminal 140. For example, the image information acquisition unit 350 may acquire the image captured by the worker terminal 140 and the information indicating the position of the worker terminal 140. The wiring information acquisition unit 310 may acquire wiring information indicating the three-dimensional arrangement of the electric wires L provided in the space including the position of the worker terminal 140. The control unit 340 may superimpose the three-dimensional arrangement of the electric wires L in the live line state on the image acquired by the image information acquisition unit 350 and display the image on the worker terminal 140. For example, the control unit 340 may cause the worker terminal 140 to display the wiring superimposed image shown in FIG. 2 by transmitting it to the worker terminal 140.

The energization information acquisition unit 320 may acquire at least the information detected by the energization sensor that detects the energization state of the electric wire L. The identifying unit 330 may identify the electric wire L that is in a live state based on the information detected by the energization sensor. The control unit 340 extracts an image of the electric wire L in a live state in the image based on the position of the energization sensor and the position corresponding to the position of the energization sensor in the image, and emphasizes the extracted image of the electric wire L. And display it. This display form will be described with reference to FIG. 13 and the like.

The control unit 340 generates, based on the wiring information, a three-dimensional model image in a virtual space, which is a virtual mapping of a predetermined space, showing the arrangement of the electric wires L in a live state, and the worker terminal 140. May be displayed. This display form will be described with reference to FIG.

The power distribution facility may include a plurality of circuit breakers whose power supply side terminals are electrically connected to each other. Based on the wiring information, the control unit 340 generates an image in which the areas occupied by the electric wires L electrically connected to the same circuit breaker among the electric wires L in the live state are displayed in the same display mode. And may be displayed on the worker terminal 140. For example, the control unit 340 may cause the worker terminal 140 to display an image in which the regions occupied by the electric wires L electrically connected to the same circuit breaker are displayed in the same color.

FIG. 4 is a diagram for explaining a wiring model showing the arrangement of electric wires in the factory 50. The wiring model includes placement information indicating the placement of each electric wire L. The placement information includes, for example, the three-dimensional coordinates PLi (i is a natural number of 1 to 8) of a plurality of nodes that represent the path of the electric wire L in the three-dimensional space.

The wiring model includes building information indicating a range occupied by the building of the factory 50. The building information includes, for example, three-dimensional coordinates PBi (i is a natural number from 1 to 8) of a plurality of nodes representing the shape of the building in the three-dimensional space. The placement information and the three-dimensional coordinates of the building node are coordinates of a three-dimensional orthogonal coordinate system having a predetermined point as the origin.

FIG. 5 schematically shows the configuration of the distribution board 72. The distribution board 72 includes a main overcurrent breaker B10, a branch current breaker B11, a branch current breaker B12, and a branch current breaker B13. L10 from the switchboard 70 is electrically connected to the power supply side terminal of the main overcurrent breaker B10. The branch current breaker B11, the branch current breaker B12, and the branch current breaker B13 are electrically connected to the load side terminals of the main overcurrent breaker B10. The electric wire L11 is electrically connected to the load side terminal of the branch current circuit breaker B11. The electric wire L12 is electrically connected to the load side terminal of the branch current circuit breaker B12. The electric wire L13 is electrically connected to the load side terminal of the branch current breaker B13.

The main overcurrent circuit breaker B10, the branch current circuit breaker B11, the branch current circuit breaker B12, and the branch current circuit breaker B13 are in an open state when an overcurrent flows to break the electric circuit. In FIG. 5, the main overcurrent circuit breaker B10 and the branch overcurrent circuit breaker B11 are closed, and the branch overcurrent circuit breaker B12 and the branch overcurrent circuit breaker B13 are open. The distribution board 72 transmits the open/closed states of the main overcurrent breaker B10, the branch current breaker B11, the branch current breaker B12, and the branch current breaker B13 to the server 130 via the network 110.

FIG. 6 shows an example of the wiring information included in the wiring model in a table format. The wiring information associates a location ID, an electric wire ID, a power supply side ID, a load side ID, and a route.

The "place ID" stores identification information of the place where the electric wire L is provided. For example, the identification information of the factory 50 is stored in the “location ID” of the electric wire L provided in the factory 50. The specifying unit 330 specifies the factory 50 based on the imaging position included in the image information received from the worker terminal 140, refers to the wiring information associated with the specified identification information of the factory 50, and identifies the factory 50. Extract the ID of the electric wire that is placed.

The "power supply side ID" stores the identification information of the device or the electric wire connected to the power supply side of the electric wire L. The "load side ID" stores the identification information of the device or the electric wire connected to the load side of the electric wire L. For example, since the branch current circuit breaker B11 is connected to the power supply side of the electric wire L11, the identification information of the branch current circuit breaker B11 is stored in the “power supply side ID” of the electric wire L11. Further, since the lighting device D12 and the electric wire L111 are connected to the load side of the electric wire L11, the identification information of each of the lighting device D12 and the electric wire L111 is stored in the “load side ID” of the electric wire L11.

In the “route”, three-dimensional coordinates of each of a starting point, a node, and an ending point indicating the arrangement of the electric wires L are stored as an array in order from the power source side to the load side. For example, the three-dimensional coordinate array of PL1 to PL6 is stored in the “route” of the electric wire L11.

FIG. 7 shows an example of the connection information included in the wiring model in a table format. The connection information represents the electrical connection relationship of the device. The connection information associates the "power supply side ID" with the "load side ID".

The "power supply side ID" stores identification information of the power supply side device which is a device provided on the power supply side. The "load side ID" stores the identification information of the load side device which is a device electrically connected to the load side of the power source side device. For example, in the distribution board 72, the branch overcurrent circuit breaker B11, the branch overcurrent circuit breaker B12, and the branch overcurrent circuit breaker B13 are electrically connected to the load side of the main overcurrent circuit breaker B10. Therefore, the identification information of the main overcurrent circuit breaker B10 is stored in the "power supply side ID" of the main overcurrent circuit breaker B10, and the branch overcurrent circuit breaker B11 and the branch overcurrent circuit breaker are stored in the "load side ID". The identification information of each of B12 and the branch overcurrent breaker B13 is stored. When the switchboard 70 includes the circuit breaker B1 connected to the electric wire L10 and the circuit breaker B0 electrically connected to the power supply side terminal of the circuit breaker B1, the “power supply side ID” includes the circuit breaker B0. The identification information is stored, and the identification information of the circuit breaker B1 is stored in the “load side ID”.

The identifying unit 330 refers to the connection information and identifies whether or not a specific position on the power distribution path is in the energized state. For example, when the main overcurrent circuit breaker B10 is in the open state, the identifying unit 330 causes the branch overcurrent circuit breaker B11, the branch overcurrent circuit breaker B12, which correspond to the “load side ID” of the main overcurrent circuit breaker B10, It is determined that the branch overcurrent circuit breaker B13 is in the non-energized state. On the other hand, when the main overcurrent circuit breaker B10 is in the closed state, the identifying unit 330 causes the branch overcurrent circuit breaker B11, the branch overcurrent circuit breaker B12, which correspond to the “load side ID” of the main overcurrent circuit breaker B10, It is determined that the respective power supply side positions of the branch overcurrent circuit breaker B13 are in the energized state.

When the branch overcurrent circuit breaker B11 is in the open state, the identifying unit 330 determines that the load side position of the branch overcurrent circuit breaker B11 is in the non-energized state, and the main overcurrent circuit breaker B10 is in the closed state. When the branch overcurrent circuit breaker B11 is closed, it is determined that the load side position of the branch overcurrent circuit breaker B11 is in the energized state. Similarly, when the branch overcurrent circuit breaker B12 is in the open state, the identifying unit 330 determines that the load side position of the branch overcurrent circuit breaker B12 is in the non-energized state, and the main overcurrent circuit breaker B10 is in the closed state. And the branch overcurrent circuit breaker B12 is closed, it is determined that the position of the branch overcurrent circuit breaker B12 on the load side is in the energized state. When the branch overcurrent circuit breaker B13 is in the open state, the identifying unit 330 determines that the load side position of the branch overcurrent circuit breaker B13 is in the non-energized state, and the main overcurrent circuit breaker B10 is in the closed state. When the branch overcurrent circuit breaker B13 is closed, it is determined that the load side position of the branch overcurrent circuit breaker B13 is in the energized state.

Further, the identifying unit 330 further refers to the wiring information and determines whether or not each electric wire is in a live state. For example, when it is determined that the load sides of the branch overcurrent circuit breaker B11, the branch overcurrent circuit breaker B12, and the branch overcurrent circuit breaker B13 are in the non-energized state, the specifying unit 330 determines that the branch overcurrent circuit breaker B11, It is specified that the electric wire L11, the electric wire L12, and the electric wire L13 associated with the identification information of the branch overcurrent circuit breaker B12 and the branch overcurrent circuit breaker B13 are not in a live state. On the other hand, for example, when the specifying unit 330 determines that the load side of the branch overcurrent circuit breaker B11 is in the energized state, the specifying unit 330 determines that the electric wire L11 connected to the load side of the branch overcurrent circuit breaker B11 is live. Identify as being in a state.

The wiring model may be generated from the design data of the factory 50. The wiring model may be generated from the data used to build a simulation model for analyzing the operating state of the factory 50 by so-called digital twin technology.

FIG. 8 shows an example of energization determination information in a table format. The energization determination information is stored in the storage unit 380. The energization determination information associates the information ID, the target ID, and the determination condition with each other.

The "information ID" stores the identification information of the information used to determine the energized state. The "target ID" stores the identification information of the device or the electric wire which is the target of the determination of the energization state. The “determination condition” stores information indicating a condition for determining whether the target device or electric wire is in the energized state.

As an example, the condition of “V0 or more” is stored as the determination condition for determining the energization state of the electric wire L0 based on the information obtained by the sensor 90. For example, when the voltage value detected by the voltage sensor of the electric wire L0 is V0 or more, the identifying unit 330 determines that the electric wire L0 is in the energized state, and the voltage value detected by the voltage sensor of the electric wire L0 is V0. When it is less than, it is determined that the electric wire L0 is in a non-energized state.

Moreover, the condition of "closed" is stored in the determination condition of the open/closed state of the main overcurrent circuit breaker B10 to be determined. For example, when the open/close state signal of the main overcurrent circuit breaker B10 indicates “closed”, the identifying unit 330 determines that the main overcurrent circuit breaker B10 is in the energized state, and the open/close state of the main overcurrent circuit breaker B10. When the signal indicates "open", it is determined that the main overcurrent breaker B10 is in the non-energized state.

In addition, the condition of "power-on" is stored as the determination condition of the power state of the machine M1 to be determined. For example, the identifying unit 330 determines that the machine M1 is in the energized state when the power-on signal indicating that the power switch of the machine M1 is in the on state is received from the machine M1.

FIG. 9 shows a display example when there is a discrepancy in the determination result of the hot line state. When the branch overcurrent circuit breaker B12 is "open", it is determined that the position of the branch overcurrent circuit breaker B12 is in a non-energized state. Therefore, it is determined that the electric wire L12 connected to the load side terminal of the branch overcurrent circuit breaker B11 is not in a live wire state.

Here, when the power-on signal is received from the machine M1, it is determined that the device M1 is in the energized state. In this case, the electric wire L12 connected to the power supply side of the machine M1 is determined to be in a live line state.

Thus, the determination result of the live line of the electric wire L12 based on the energized state of the branch overcurrent circuit breaker B12 on the power source side of the electric wire L12 and the determination result of the electric wire L12 based on the energized state of the machine M1 on the load side of the electric wire L12 are When they are different, the control unit 340 considers the electric wire L12 to be in a live-line state, and sets the object 240 indicating the arrangement of the electric wire L12 as the object 230 indicating the arrangement of the electric wire L11 in the live state and the live-line state. The mode is different from that of the object 250 indicating the arrangement of the electric wire L13 not included in the above. For example, the color of the object 240 is made different from both the color of the object 230 and the color of the object 250. Thereby, the worker 80 can be alerted.

FIG. 10 is a flowchart showing an example of hot line monitoring processing executed by the worker terminal 140. The process of this flowchart is started when the hot-line confirmation application is started in the worker terminal 140. The process of this flowchart is mainly executed by the processor of the worker terminal 140 controlling each unit of the worker terminal 140.

In S902, the worker terminal 140 starts the image capturing operation of the image capturing unit included in the worker terminal 140. In step S904, the image information including the image captured by the image capturing unit and the image capturing condition of the image is transmitted to the server 130, and the provision of the hot-line arrangement is requested. The image capturing condition includes information indicating the position of the worker terminal 140, the image capturing direction of the image capturing unit, and the angle of view of the image capturing unit. The position of the worker terminal 140 may be specified based on the positioning information of the GPS sensor. The imaging direction of the imaging unit may be specified based on the acceleration information detected by the azimuth sensor included in the worker terminal 140 and the acceleration sensor included in the worker terminal 140.

Upon receiving the wiring superimposed image from the server 130 in S906, the worker terminal 140 displays the received wiring superimposed image on the display of the worker terminal 140 in S908. In S910, the worker terminal 140 determines whether or not the imaging range of the imaging unit has changed. For example, the worker terminal 140 changes the shooting range of the worker terminal 140 based on the position of the worker terminal 140, the orientation of the worker terminal 140, and the change of the angle of view of the imaging unit included in the worker terminal 140. I judge that I did. Note that the worker terminal 140 may specify the amount of change in the position and orientation of the worker terminal 140 based on the change over time in the acceleration detected by the acceleration sensor included in the worker terminal 140. The worker terminal 140 may specify the amount of change in the angle of view of the imaging unit based on the amount of operation of the angle of view that the worker 80 has instructed to the worker terminal 140. If the imaging range of the imaging unit has changed, the process proceeds to S904.

When the imaging range has not changed, in S920, the worker terminal 140 determines whether or not the wiring superimposed image push-transmitted from the server 130 has been received. Push transmission of the wiring superimposed image will be described with reference to FIG. When the wiring superimposed image push-transmitted from the server 130 is received, the process proceeds to S908.

When the wiring superimposed image transmitted by push from the server 130 has not been received, it is determined in S922 whether or not to terminate the hot line confirmation operation. For example, when the worker terminal 140 receives an instruction from the worker 80 to terminate the live-line confirmation application, the worker terminal 140 determines to end the live-line confirmation operation. When the hot line confirmation operation is not finished, the process proceeds to S904. When terminating the live line confirmation operation, the image capturing operation of the image capturing unit is terminated in S924, a live line monitoring termination notification is transmitted to the worker terminal 140 in S926, and the processing of this flowchart is terminated.

FIG. 11 is a flowchart showing an example of hot line monitoring processing executed by the server 130. The process of this flowchart is started when the image information acquisition unit 350 receives the image information from the worker terminal 140 and is requested to provide the hot-line arrangement. The processing of this flowchart is executed mainly by the processing unit 300 included in the server 130 controlling each unit of the server 130.

In S1002, the identifying unit 330 identifies the target space for hot line confirmation based on the imaging position included in the image information. For example, the identifying unit 330 identifies the factory 50 in which the building exists in the geographical range including the image capturing position as the target space, and acquires the identification information of the factory 50.

In step S1004, the wiring information acquisition unit 310 acquires wiring model data, and the energization information acquisition unit 320 acquires energization determination information. For example, the wiring information acquisition unit 310 refers to the wiring information included in the wiring model data described with reference to FIG. 6, and acquires the electric wire ID associated with the identification information of the factory 50 specified in S1002. Further, the wiring information acquisition unit 310 acquires the identification information of the device or the wiring of the power supply side ID and the load side ID corresponding to the electric wire ID, and refers to the connection information described with reference to FIG. A device that can be electrically connected to the electric wire L provided in 50 is specified. In addition, the wiring information acquisition unit 310 refers to the target ID of the energization information described with reference to FIG. 8, and the information ID associated with the electric wire L provided in the factory 50 and the device provided in the factory 50. Specify. In addition, the energization information acquisition unit 320 includes sensor data associated with the information ID specified by the wiring information acquisition unit 310, opening/closing information such as circuit breakers of the distribution board 70 and the distribution board 72, and power supplies of the machines M1 and M2. The status is read from the storage unit 380.

In S1006, the identifying unit 330 identifies the electric wire L that is in a live wire state and the electric wire L that may be in a live wire state. For example, the identifying unit 330 identifies the electric wire L in a live line state by using the information described with reference to FIGS. 4 to 8. In step S1008, the control unit 340 generates a wiring superimposed image. The control unit 340 generates a wiring superimposed image as shown in FIG. 2 and FIG. 9, for example. In S1010, the control unit 340 transmits the wiring superimposed image.

In step S1020, the image information acquisition unit 350 determines whether new image information has been received from the worker terminal 140. When new image information is received from the worker terminal 140, the process proceeds to S1002. When new image information is not received from the worker terminal 140, the control unit 340 determines in step S1022 whether or not the current is detected based on the current detection result of the sensor 90, the open/closed state of each circuit breaker, and the power state of each machine. Determine if the results have changed. If the energization determination information has changed, the process proceeds to S1002. When the process proceeds to S1002 in response to the change in the energization determination information, a wiring superimposed image is generated in S1010 and push-transmitted to the worker terminal 140.

When it is determined in S1022 that the sensor information has not changed, in S1024, the control unit 340 determines whether or not to terminate the hot line monitoring process. For example, when the hotline monitoring process end notification is received from the worker terminal 140, the hotline monitoring process is determined to be ended. When the hot line monitoring process is not finished, the process proceeds to S1020.

As described above, according to the system 100, the worker 80 determines in which position in the factory 50 the worker 80 is located, and in which direction the worker 80 faces. The live state of the electric wire existing in the facing direction can be presented to the worker 80 in an easily recognizable manner.

FIG. 12 shows another display example of the arrangement of electric wires in a live state. The control unit 340 of the server 130 uses the wiring model data to generate a model image 1280 in a virtual space that virtually maps the actual factory 50, and displays the model image 1280 on the worker terminal 140. In FIG. 12, an object 1200 shows an arrangement of L0 in a hot line state. Similarly, an object 1210, an object 1211 and an object 12111 respectively indicate arrangements of L10, L11 and L111 which are in a hot line state. An object 1212 and an object 1213 respectively indicate the arrangement of L12 and L13 that are not in a hot line state.

The control unit 340 may generate a model image in which an electric wire in a live state is emphasized over an electric wire in a non-live state, similarly to the aspect in which the arrangement of electric wires is displayed in a superimposed manner on the captured image described above. For example, the control unit 340 may make the thickness of the electric wire in the live wire state larger than the thickness of the electric wire in the non-live wire state. Further, the control unit 340 may make the color of the electric wire in the live state different from the color of the electric wire in the non-live state. The control unit 340 may display the object 1211 and the object 12111 corresponding to the electric wire L11 and the electric wire L111 electrically connected to the same branch overcurrent circuit breaker B11 in the same color. Thereby, the worker 80 can easily recognize which electric wire is connected to the same branch overcurrent breaker.

FIG. 13 shows an image displayed on the worker terminal 140 in the modified example of the system 100. In addition to the function of the system 100 described above, this modification has a function of extracting a live wire image from an image captured by the worker terminal 140 and displaying the arrangement of the wire image.

It is assumed that the electric wire L14 is further provided in the factory 50. A sensor 1310 is provided on the electric wire L14. The sensor 1310 detects a current flowing through the electric wire L14. The sensor 1310 transmits sensor information including information indicating the detected current value and position information indicating the position where the sensor 1310 is provided to the surroundings.

When the worker terminal 140 receives the sensor information from the sensor 1310, the worker terminal 140 extracts the position information from the sensor information and specifies the position of the sensor 1310. The worker terminal 140 determines whether or not the position of the sensor 1310 is included in the imaging range of the imaging unit of the worker terminal 140. For example, the worker terminal 140 identifies the image capturing range of the image capturing unit based on the position of the worker terminal 140, the image capturing direction of the image capturing unit, and the angle of view of the image capturing unit, and detects the sensor 1310 within the identified image capturing range. Determine if a position is included. When the position of the sensor 1310 is included in the imaging range, the worker terminal 140 extracts the electric wire image from the image area corresponding to the position of the sensor 1310 in the image 290 obtained by the imaging operation of the imaging unit. For example, the worker terminal 140 extracts an electric wire image from the image 290 by pattern matching or the like. The worker terminal 140 generates an object 1320 that emphasizes the area of the electric wire image in the captured image, superimposes it on the image 290, and displays it on the display of the worker terminal 140. According to this modification, it may be possible to present the worker 80 with the arrangement of the electric wires in a live state without depending on the wiring model data. Note that as the sensor 1310, any sensor such as a voltage detector or a voltage sensor that can detect the live state of the electric wire can be applied in addition to the current sensor.

In the embodiment described above, the worker terminal 140 is assumed to be a mobile terminal. The worker terminal 140 may be eyewear. When the worker terminal 140 as the eyewear is used, the worker terminal 140 may present the arrangement of the electric wires in a live state within the sight of the worker 80 by using the augmented reality (AR) technology. For example, as shown in FIG. 2, FIG. 9, FIG. 13, etc., an object to be superimposed on the image 290 may be presented within the visual sense of the worker 80.

In the above, the embodiment of the system 100 and the modified example of the system 100 for the wiring model of the entire factory 50 has been described. However, as a target of the system 100 and the modified example of the system 100 described above, a wiring model of a switchboard or a distribution board alone or a machine alone may be applied. In addition, by including the line resistance in the wiring model, the magnitude of the current and the magnitude of the voltage flowing through the electric wire L are specified, and the display mode such as the color and thickness is changed according to the magnitude of the current and the magnitude of the voltage. The arrangement of the electric wires L may be displayed. As a result, not only the live line state but also the magnitude of the current and the magnitude of the voltage can be presented to the worker 80.

The system 100 has been described as having the server 130 and the worker terminal 140. However, only the server 130 can function as a system that causes the worker terminal 140 to display a three-dimensional arrangement of electric wires in a live state.

According to the system 100 and the modified example of the system 100 described above, the worker 80 can easily recognize which electric wire is in a live wire state, for example, during hot wire work. Therefore, the worker 80 can perform hot line work more safely.
