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. Also, not all combinations of features described in the embodiments are essential for the solution of the invention.

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

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 equipment M1 and the equipment 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 portable terminals include mobile phones, smart phones, tablets, PDAs, notebook computers, laptop computers, wearable computers, and the like. The worker terminal 140 may be a general-purpose computer such as a personal computer. Worker terminal 140 communicates with server 130 through 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 that is a lead-in line from the utility pole 60 to the factory 50 . The electric power drawn through the electric wire L0 is supplied to electric power loads in the factory 50 through the switchboard 70, the electric wire L10 and the switchboard 72. Switchboard 70 steps down the high voltage supplied through line L0 to the low voltage used within factory 50 . The distribution board 72 receives the low-voltage power from the distribution board 70 and distributes it to electrical devices such as lighting devices D11 and D12, machines M1 and machines M2.

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

When performing work in the factory 50 , the worker 80 uses the worker terminal 140 to check the arrangement of live wires in the factory 50 . For example, when the worker 80 activates a live line confirmation application installed in the worker terminal 140, the worker terminal 140 starts an imaging operation using the camera function of the worker terminal 140. FIG. The operator terminal 140 transmits image information including captured image data and imaging conditions including the imaging direction, the imaging position, and the angle of view of the operator terminal 140 to the server 130, and provides the live line layout to the server 130. request to.

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 stores energization information of the electric wire L0 detected by the sensor 90 associated with the factory 50, the open/close state of the disconnector and circuit breaker included in the switchboard 70 associated with the factory 50, and Based on the opened/closed state of the circuit breaker of the distribution board 72 and the wiring model information, the wiring in the active state is specified.

For example, when the voltage detected by the voltage sensor 90 is higher than a predetermined voltage and the disconnecting switch and the circuit breaker of the switchboard 70 are closed, the server 130 detects the wire When only the circuit breaker connected to L11 is in the closed state, the electric wire L0, the electric wire L10, the electric wire L11 and the electric wire L111 are identified as electric wires in the live state, and the electric wires L12 and L13 are identified as electric 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 in the live state is superimposed on the image included in the image information, and transmits the image to the operator terminal 140. The worker terminal 140 displays the wiring superimposed image acquired from the server 130 .

FIG. 2 schematically shows an example of a wiring superimposed image 200 displayed on the operator terminal 140. As shown in FIG. The server 130 stores an object 210 representing the placement of the wire L0, an object 220 representing the wire L10, an object 230 representing the placement of the wire L11, an object 240 representing the placement of the wire L12, and an object 250 representing the placement of the wire L13. are superimposed on the image 290 captured by the worker terminal 140 to generate the wiring superimposed image 200 .

When the server 130 identifies the electric wire L0, the electric wire L10, and the electric wire L11 as the electric wires in the active state among the electric wires L imaged in the image 290, the server 130 identifies the object 210, the object 220, and the object 230 as the object 240 and the object 240, respectively. Emphasize over object 250 . Accordingly, the worker 80 can easily recognize the arrangement of the electric wires in the live state by viewing the wiring superimposed image 200 . Therefore, it is possible to reduce the possibility that the worker 80 touches the live wire during work.

FIG. The lighting devices D1 and D2, the machine M1, and the machine M2 of the present embodiment are examples of electrical equipment.

The control unit 340 may cause the operator terminal 140 to display the three-dimensional arrangement of the electric wires L in the live state in a manner different from the display manner of the three-dimensional arrangement of the electric wires L that are not in the live state. For example, the control unit 340 may cause the operator terminal 140 to display the three-dimensional arrangement of the wires L in the live state in a color different from the color used to display the three-dimensional arrangement of the wires L that are not in the live state. . 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 more emphasized than the three-dimensional arrangement of the electric wires L in the non-live state.

Further, in the wiring path formed including the electric wire L, if there is a second position in an energized state on the load side of the first position that is not in an energized state, the first position and the first position are connected. The operator terminal 140 may display the three-dimensional arrangement of the electric wires L between the two positions. For example, the control unit 340 can display the three-dimensional arrangement of the electric wires L between the first position and the second position in a manner different from the display manner of the three-dimensional arrangement of the electric wires L in the active state. It may be displayed on the 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 state on the image acquired by the image information acquisition unit 350 and cause the worker terminal 140 to display the image.

The building information includes, for example, three-dimensional coordinates PBi (i is a natural number from 1 to 8) of a plurality of nodal points representing the shape of the building in the three-dimensional space. The arrangement information and the three-dimensional coordinates of the building nodes are coordinates of a three-dimensional orthogonal coordinate system with a predetermined point as the origin.

FIG. 5 schematically shows the configuration of the distribution board 72. As shown in FIG. The distribution board 72 includes a main overcurrent circuit breaker B10, a branch current circuit breaker B11, a branch current circuit breaker B12, and a branch current circuit breaker B13. L10 from the switchboard 70 is electrically connected to the power supply side terminal of the main overcurrent circuit 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. A wire L11 is electrically connected to the load side terminal of the branch current breaker B11. A wire L12 is electrically connected to the load side terminal of the branch current breaker B12. A 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 opened to cut off the electric circuit when an overcurrent flows. In FIG. 5, the main overcurrent circuit breaker B10 and branch overcurrent circuit breaker B11 are closed, and the branch overcurrent circuit breaker B12 and branch overcurrent circuit breaker B13 are open. The distribution board 72 transmits the switching states of 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 to the server 130 via the network 110. FIG.

FIG. 6 shows an example of wiring information included in the wiring model in a table format. The wiring information associates location IDs, wire IDs, power supply side IDs, load side IDs, and routes with each other.

Identification information of the place where the electric wire L is provided is stored in the "location ID". For example, the identification information of the factory 50 is stored in the "place ID" of the electric wire L provided in the factory 50. FIG. The identifying unit 330 identifies 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 identification information of the identified factory 50, and Extract the arranged electric wire ID.

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

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

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

The “power supply side ID” stores identification information of a power supply side device that is provided on the power supply side. The “load side ID” stores identification information of the load side device that is electrically connected to the load side of the power source side device. For example, in the distribution board 72, a branch overcurrent circuit breaker B11, a branch overcurrent circuit breaker B12, and a 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". Identification information of each of B12 and branch overcurrent circuit breaker B13 is stored. When the switchboard 70 includes the circuit breaker B1 connected to the 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" of the circuit breaker B0 is 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 an energized state. For example, when the main overcurrent circuit breaker B10 is in an open state, the identification unit 330 selects the branch overcurrent circuit breaker B11, branch overcurrent circuit breaker B12, It is determined that the branch overcurrent circuit breaker B13 is in a non-energized state. On the other hand, when the main overcurrent circuit breaker B10 is in the closed state, the identifying unit 330 determines the branch overcurrent circuit breaker B11, branch overcurrent circuit breaker B12, It is determined that each power supply side position of the branch overcurrent circuit breaker B13 is in an energized state.

Further, when the branch overcurrent circuit breaker B11 is in the open state, the identification unit 330 determines that the load side position of the branch overcurrent circuit breaker B11 is in the non-energized state, and when the main overcurrent circuit breaker B10 is in the closed state. If there is and the branch overcurrent circuit breaker B11 is in the closed state, it is determined that the position on the load side 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 identification 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 load side position of the branch overcurrent circuit breaker B12 is in an energized state. Further, when the branch overcurrent circuit breaker B13 is in the open state, the identification unit 330 determines that the load side position of the branch overcurrent circuit breaker B13 is in the non-energized state, and when the main overcurrent circuit breaker B10 is in the closed state. If there is and the branch overcurrent circuit breaker B13 is closed, it is determined that the position on the load side of the branch overcurrent circuit breaker B13 is in the energized state.

In addition, the identification unit 330 further refers to the wiring information to determine whether or not each wire is live. For example, when determining 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 a non-energized state, the specifying unit 330 detects the branch overcurrent circuit breaker B11, 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 specified as not in the live line state. On the other hand, for example, when the identifying unit 330 determines that the load side of the branch overcurrent circuit breaker B11 is in an energized state, the identifying unit 330 determines that the electric wire L11 connected to the load side of the branch overcurrent circuit breaker B11 is live. identify the condition.

Note that the wiring model may be generated from the design data of the factory 50 . A wiring model may be generated from data used to build a simulation model for analyzing the operating conditions of the factory 50 through 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 information IDs, target IDs, and determination conditions.

"Information ID" stores identification information of information used to determine the energized state. The “target ID” stores identification information of a device or a wire whose energized state is to be determined. The "determination condition" stores information indicating a condition for determining whether or not the target device or electric wire is in an energized state.

As an example, a condition of “V0 or more” is stored as a judgment condition for judging the energized 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 an energized state, and the voltage value detected by the voltage sensor of the electric wire L0 is V0 If it is less than that, it is determined that the electric wire L0 is in a non-energized state.

In addition, a condition of "closed" is stored as the determination condition for the open/closed state of the main overcurrent circuit breaker B10 to be determined. For example, when the switching state signal of the main overcurrent circuit breaker B10 indicates "closed", the identification unit 330 determines that the main overcurrent circuit breaker B10 is in the energized state, and determines that the switching state of the main overcurrent circuit breaker B10 is When the signal indicates "open", it is determined that the main overcurrent circuit breaker B10 is in a non-energized state.

In addition, a condition of “power on” is stored as a determination condition for the power state of the machine M1 to be determined. For example, the identification unit 330 determines that the machine M1 is in the energized state when a 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 live 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 the de-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 live.

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

In this way, 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 supply 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 combined. If not, the control unit 340 determines that the electric wire L12 may be in the live state, and replaces the object 240 indicating the arrangement of the electric wire L12 with the object 230 indicating the arrangement of the electric wire L11 in the live state and the live state. The mode is different from that of the object 250 showing the arrangement of the electric wire L13 which is not in the . For example, the color of object 240 is made different from both the color of object 230 and the color of object 250 . Accordingly, the operator 80 can be alerted.

FIG. 10 is a flow chart showing an example of the live line monitoring process executed by the operator terminal 140. As shown in FIG. The processing of this flowchart is started when the live line confirmation application is activated in the worker terminal 140 . The processing of this flowchart is mainly executed by controlling each part of the worker terminal 140 by a processor included in the worker terminal 140 .

In S<b>902 , the worker terminal 140 starts the imaging operation of the imaging unit provided in the worker terminal 140 . In S904, the image information including the image captured by the image capturing unit and the image capturing conditions of the image is transmitted to the server 130 to request provision of hot line layout. The imaging condition of the image includes information indicating the position of the worker terminal 140, the imaging direction of the imaging unit, and the angle of view of the imaging unit. The position of 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 acceleration information detected by an orientation sensor provided in the worker terminal 140 or an acceleration sensor provided 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 imaging 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 in the angle of view of the imaging unit provided in the worker terminal 140. judge that it 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 temporal change in acceleration detected by the acceleration sensor included in the worker terminal 140 . The operator terminal 140 may specify the amount of change in the angle of view of the imaging unit based on the amount of angle-of-view operation instructed by the operator 80 to the operator 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 operator terminal 140 determines whether or not the wiring superimposed image push-transmitted from the server 130 has been received. The push transmission of the wiring superimposed image will be described with reference to FIG. 10 and the like. When the wiring superimposed image push-transmitted from the server 130 is received, the process proceeds to S908.

If the wiring superimposed image push-transmitted from the server 130 has not been received, it is determined in S922 whether or not to end the live line checking operation. For example, the worker terminal 140 determines to end the live line checking operation when an instruction to end the live line checking application is received from the worker 80 . If the live line confirmation operation is not to end, the process proceeds to S904. When the live line checking operation is to be ended, the imaging operation of the imaging unit is ended in S924, and a live line monitoring end notification is transmitted to the operator terminal 140 in S926, and the processing of this flowchart is ended.

FIG. 11 is a flow chart showing an example of live line monitoring processing executed by the server 130 . The processing of this flowchart is started when the image information acquisition unit 350 receives image information from the operator terminal 140 and is requested to provide hot line layout. The processing of this flowchart is mainly executed by the processing unit 300 provided in the server 130 controlling each unit of the server 130 .

In S1002, the specifying unit 330 specifies the target space for live line confirmation based on the imaging position included in the image information. For example, the specifying unit 330 specifies the factory 50 having a building in a geographical range including the imaging position as the target space, and acquires the identification information of the factory 50 .

In 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. In addition, the wiring information acquisition unit 310 acquires the identification information of the device or 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 in connection with FIG. A device that can be electrically connected to the wire L provided in 50 is specified. The wiring information acquisition unit 310 also refers to the target ID of the energization information described with reference to FIG. identify. In addition, the energization information acquisition unit 320 acquires sensor data associated with the information ID specified by the wiring information acquisition unit 310, opening/closing information such as circuit breakers of the switchboard 70 and the switchboard 72, and power supply of the machine M1 and the machine M2. The state is read from storage unit 380 .

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

In S<b>1020 , the image information acquisition unit 350 determines whether or not new image information has been received from the operator terminal 140 . When new image information is received from the operator terminal 140, the process proceeds to S1002. If new image information has not been received from the operator terminal 140, the control unit 340 determines in S1022 whether or not the control unit 340 is energized 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. Note that when the process proceeds to S<b>1002 in response to a change in the energization determination information, a wiring superimposed image is generated in S<b>1010 and push-transmitted to the operator terminal 140 .

If it is determined in S1022 that the sensor information has not changed, in S1024 control unit 340 determines whether or not to end the live line monitoring process. For example, when a live-line monitoring process end notification is received from the worker terminal 140, it is determined to end the live-line monitoring process. When not ending the live line monitoring process, the process proceeds to S1020.

As described above, according to the system 100, the position of the worker 80 in the factory 50 and the direction in which the worker 80 is facing in the factory 50 are determined. It is possible to present the active wire state of the electric wire existing in the facing direction to the operator 80 in an easy-to-recognize manner.

FIG. 12 shows another display example of the arrangement of wires in a live state. The controller 340 of the server 130 uses the wiring model data to generate a virtual space model image 1280 in which the actual factory 50 is virtually mapped, and causes the operator terminal 140 to display the model image 1280 . In FIG. 12, object 1200 shows the placement of L0 in a live state. Similarly, objects 1210, 1211, and 12111 indicate the locations of active L10, L11, and L111, respectively. Objects 1212 and 1213 show the placement of non-live L12 and L13, respectively.

As in the case of superimposing the arrangement of electric wires on the captured image described above, the control unit 340 may generate a model image in which live electric wires are emphasized more than non-live electric wires. For example, the control unit 340 may make the thickness of the wire in the live state thicker than the thickness of the wire in the non-live state. Further, the control unit 340 may make the color of the electric wires in the live state different from the color of the electric wires that are not in the live state. Note that 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. This allows operator 80 to easily recognize which wires are connected to the same branch overcurrent circuit breaker.

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

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

When worker terminal 140 receives sensor information from sensor 1310 , worker terminal 140 extracts position information from the sensor information and identifies the position of sensor 1310 . The worker terminal 140 determines whether or not the position of the sensor 1310 is included within the imaging range of the imaging unit of the worker terminal 140 . For example, the worker terminal 140 specifies the imaging range of the imaging unit based on the position of the worker terminal 140, the imaging direction of the imaging unit, and the angle of view of the imaging unit, and the sensor 1310 is positioned within the specified imaging range. Determines whether the 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 the 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 modified example, it may be possible to present the arrangement of live electric wires to the worker 80 without depending on the wiring model data. As the sensor 1310, any sensor capable of detecting the live wire state of the electric wire, such as a voltage detector or a voltage sensor, can be applied other than the current sensor.

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

In the above, the embodiment of the system 100 for the wiring model of the entire factory 50 and the modification of the system 100 has been described. However, as a target of the above-described system 100 and modifications of the system 100, a wiring model of a switchboard, a single switchboard, or a single machine may be applied. In addition, the line resistance is included in the wiring model, the magnitude of the current flowing through the electric wire L and the magnitude of the voltage are specified, and the display mode such as color and thickness is changed according to the magnitude of the current and voltage. You may display the arrangement|positioning of the electric wire L by pressing. This makes it possible to present to the operator 80 not only the state of the live line but also the magnitude of the current and the magnitude of the voltage.

In addition, the form provided with the server 130 and the worker terminal 140 as the system 100 was demonstrated. However, only the server 130 can function as a system that causes the worker terminal 140 to display the three-dimensional arrangement of the electric wires in the 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 live during, for example, live wire work. Therefore, the worker 80 can perform the live line work more safely.
