It is assumed that the terminal device 20 is in a state of being logged in to the server 30 by transmitting a predetermined user ID and password to the server 30.

After performing a predetermined inspection work at the place Pa (for example, in the company) where the voltage detector 10 is stored, the worker and the supervisor perform the predetermined inspection work, and then the site where the voltage detection object (for example, the distribution line 5) is provided. Imagine a scene where you move to Pb and perform voltage detection on the object to be detected. Typically, the following processes of sequences SQ10 to SQ36 are executed at the location Pa, and the processes of the sequences SQ38 to SQ54 are executed at the site Pb.

In the present embodiment, a series of operations related to voltage detection is composed of four operations. Specifically, the first work W1 is a work of confirming whether the internal circuit of the voltage detector 10 and the battery voltage are normal by using the test button 108 at the site Pa (that is, the soundness of the voltage detector 10).

As a result, the supervisor can instruct the worker to perform the work W2. The operator himself / herself may visually recognize the display 208 of the terminal device 20. The order of the sequences SQ24 and SQ26 is not limited to this, and the order is random.

According to the instruction from the supervisor, the operator applies a voltage to the detection sensor 110 of the voltage detector 10 using a known power source (for example, a voltage detector checker) (sequence SQ28). When the voltage detector 10 detects the voltage, the voltage detector 10 transmits a detection result indicating that the energization state is detected by the detection sensor 110 of the voltage detector 10 to the terminal device 20 (sequence SQ30). The detection result includes the voltage detector ID of the voltage detector 10 and information indicating that the energization state has been detected. At this time, the voltage detector 10 outputs audio and emits light according to the result indicating energization.

Information prompting the execution of (that is, work W3) is displayed on the display 208 (sequence SQ36). As a result, the supervisor can instruct the worker to perform the work W3. The order of the sequences SQ34 and SQ36 is not limited to this, and the order is random.

Supervisors and workers move from location Pa to site Pb. The operator presses the test button 108 of the voltage detector 10 (sequence SQ38). Upon receiving the input of the test button 108, the voltage detector 10 transmits operation confirmation information indicating that the internal circuit and the battery voltage are normal to the terminal device 20 (sequence SQ40).

The terminal device 20 receives the operation confirmation information and displays that the operation is normal (sequence SQ42). When the terminal device 20 receives an instruction from the supervisor to approve the completion of the work W3, the terminal device 20 transmits the history information of the work W3 to the terminal device 20 (sequence SQ44). The history information of the work W3 includes a user ID, a current date and time, a voltage detector ID, identification information of the work W3, a work result of the work W3, a position information of the terminal device 20, and approval information.

It is displayed on the display 208 (sequence SQ46). As a result, the supervisor can instruct the worker to work W4. The order of the sequences SQ44 and SQ46 is not limited to this, and the order is random.

According to the instruction from the supervisor, the operator brings the detection sensor 110 into contact with the inspection object (here, the distribution line 5). The voltage detector 10 detects the energization of the distribution line 5 (sequence SQ48), and transmits a detection result indicating that the energization has been detected to the terminal device 20 (sequence SQ50). At this time, the voltage detector 10 outputs audio and emits light according to the result indicating energization.

The terminal device 20 receives the detection result and displays the result indicating energization (sequence SQ52). If the distribution line 5 is not energized, the detection result is not transmitted from the voltage detector 10, so that the above display is not performed.

With reference to FIG. 5, the history information database 500 is a set of history information including a user ID, a date and time, a voltage detector ID, a work ID, a work result, a position information, and approval information. The history information may further include the terminal ID of the terminal device 20.

The user ID is the ID of the user who was logged in when each work was performed. The date and time information indicates the date. The voltage detector ID is identification information of the voltage detector 10 (for example, the serial number of the voltage detector 10). The work ID indicates the identification information (for example, the order of each work) of each work W1 to W4 described above. Therefore, the work IDs of the work W1, W2, W3, and W4 are "1", "2", "3", and "4", respectively.

As a specific example, the terminal device 20 (hereinafter, also referred to as “terminal device 20u1”) logged in with the user ID “U1” is set on the date and time “September 14, 2017 16:32:37” in the company or the like. Supervise the work result "test OK" of the work W1 using the voltage detector 10 (hereinafter, also referred to as "voltage detector 10e5") of the voltage detector ID "E5" at the position "A city B town" indicating the place Pa. Is sending in an unapproved state. Two minutes later, at the date and time "September 14, 2017 16:34:37", the terminal device 20u1 transmits the work result "test OK" of the above work W1 in a state approved by the supervisor. There is. The work result "test OK" indicates that the battery voltage and the internal circuit are normal.

Next, the terminal device 20u1 sets the work result "live line" of the work W2 using the voltage detector 10e5 at the position "A city B town" at the date and time "September 14, 2017 16:38:34". , The supervisor is sending in the approved state. The work result "live line" of the work W2 indicates that the voltage was normally detected by the voltage detector 10 (that is, the voltage detection function of the voltage detector 10 is normal).

At the date and time "September 14, 2017 19:38:54" about 3 hours after the above transmission, the terminal device 20u1 used the voltage detector 10e5 at the position "D city E town" corresponding to the site Pb. The work result "test OK" of work W3 is transmitted in a state of being approved by the supervisor. Then, the terminal device 20u1 sets the work result "no voltage" of the work W4 using the voltage detector 10e5 at the position "D city E town" at the date and time "September 14, 2017 19:39:03". It is sent in the approved state by the supervisor. The work result "no voltage" of the work W4 indicates that the voltage is not supplied to the detection target object (for example, the distribution line 5).

As another example, the history information database 500 also stores the history information from the terminal device 20 logged in with the user ID "U2" or "U3".

In this way, the terminal device 20 can confirm the history information of a series of operations related to the voltage detection on a user-by-user basis by accessing the history information database 500 stored in the server 30. It is also possible to determine whether a series of work has been carried out according to the procedure by confirming whether or not the supervisor has approved the work and whether or not the work has been omitted.

Therefore, in the work content area 602 of each screen 600 to 620, the wording "1. Pre-use inspection (test)" indicating the order of the work W1 and the outline of the work content is displayed.

An example of screen transition will be described below. When the CPU 202 starts the voltage detection application, the CPU 202 displays the screen 600, which is the initial screen, on the display 208. In the notification area 606 of the screen 600, the wording "Please test" prompting the execution of the work W1 is displayed. Since it is a stage before the test, nothing is displayed in the work result area 604 of the screen 600.

Next, when the supervisor who visually recognizes the screen 600 gives an instruction for the work W1 to the operator (or the operator himself visually recognizes the screen 600), the operator presses the test button 108 of the voltage detector 10. The voltage detector 10 receives the input by the test button 108 and transmits the operation confirmation information indicating that the internal circuit and the battery voltage are normal to the terminal device 20. Upon receiving the operation confirmation information, the terminal device 20 displays the wording "test OK" in the work result area 604 as shown in the screen 610 of FIG. 6B.

If at least one of the internal circuit and the battery voltage is abnormal, the voltage detector 10 does not transmit the above information, so that nothing is displayed in the work result area 604 as shown on the screen 600. As a result, the supervisor can determine whether or not the work W1 has been properly carried out.

If the CPU 202 does not display anything in the work result area 604 even after a lapse of a predetermined time after displaying the screen 600, the work W1 is not properly executed (that is, an abnormality is found in the voltage detector 10). A warning may be displayed (for example, the phrase "The pre-use inspection (test) could not be confirmed normally" is displayed). Further, when the selection (pressing) of the approval button 605 is accepted while nothing is displayed in the work result area 604 as shown on the screen 600, the CPU 202 determines that the work W1 has not been properly performed and warns the above. Display may be performed.

The supervisor who visually recognizes the wording "test OK" displayed on the screen 610 selects (presses) the approval button 605 in order to approve the completion of the work W1. In this case, the display screen transitions from the screen 610 to the screen 620. The wording "test operation is good" is displayed in the notification area 606 of the screen 620 shown in FIG. 6 (c). Further, in the progress status area 607, a check mark is superimposed and displayed on the word “step 1”. This indicates that the completion of work W1, which is the first work in the series of work, has been confirmed. When the supervisor confirms the update of the progress status (for example, the display of the check mark), the supervisor presses the button 608. At this time, the user interface screen for the work W2 next to the work W1 is displayed. The user interface screen related to the work W2 may be displayed after a predetermined time has elapsed after the transition to the screen 620 without pressing the button 608.

FIG. 7 is a diagram showing an example of a user interface screen relating to the second work W2 in the series of work. When the CPU 202 accepts the selection of the button 608 on the screen 620 (see FIG. 6C), the CPU 202 displays the screen 630 shown in FIG. 7A on the display 208. In the work content area 602 of the screen 630, the wording "2. Pre-use inspection (live line)" indicating the order of the work W2 and the outline of the work content is displayed. The order of work W1 and the outline of work contents are also displayed.

In the notification area 606 of the screen 630, the wording "Please use the checker" prompting the execution of the work W2 is displayed. Since the screen 630 is a screen in a state before the operation confirmation of the voltage detector 10 using the voltage detector checker, nothing is displayed in the work result area 604 of the screen 630.

Next, when the supervisor who visually recognizes the screen 630 gives an instruction to the operator to carry out the work W2 (or the operator himself visually recognizes the screen 630), the operator uses the voltage detector checker to display the voltage detector 10. A voltage is applied to the detection sensor 110.

The voltage detector 10 detects the voltage and transmits a detection result indicating that the voltage detector checker is energized (live line) to the terminal device 20. When the terminal device 20 receives the detection result, the terminal device 20 displays the word "live line" in the work result area 604 of the screen 640 shown in FIG. 7 (b).

If the energization of the voltage detector checker cannot be detected (that is, the voltage detection function of the voltage detector 10 is abnormal), the detection result is not transmitted from the voltage detector 10, so that the work result area 604 is shown on the screen 630. Leaves nothing displayed in. As a result, the supervisor can determine whether or not the work W2 has been properly carried out.

The supervisor who visually recognizes the word "live line" displayed on the screen 640 presses the approval button 605 in order to approve the completion of the work W2. In this case, the display screen transitions from the screen 640 to the screen 650. The wording "live-line operation is good" is displayed in the notification area 606 of the screen 650 shown in FIG. 7 (c). Further, in the progress status area 607, a check mark is superimposed and displayed on the word "step 2". This indicates that work W2, which is the second work in the series of work, has been completed.

When the supervisor confirms the update of the progress status (for example, the display of the check mark) on the screen 650, the supervisor presses the button 608. In this case, the user interface screen for the work W3 next to the work W2 is displayed.

FIG. 8 is a diagram showing an example of a user interface screen relating to the third work W3 in the series of work. When the CPU 202 accepts the selection of the button 608 on the screen 650 (see FIG. 7C), the CPU 202 displays the screen 660 of FIG. 8A on the display 208. Work W3 is work carried out at the site Pb. In the work content area 602 of the screen 660, the wording “3. Field test” indicating the order of the work W3 and the outline of the work content is displayed. The order of each work W1 and W2 and the outline of the work contents are also displayed.

In the notification area 606 of the screen 660, the wording "Please test" prompting the execution of the work W3 is displayed. Since the screen 660 is a screen of the situation before the test, nothing is displayed in the work result area 604.

When the supervisor who visually recognizes the screen 660 gives an instruction for the work W3 to the worker, the worker presses the test button 108 of the voltage detector 10. The voltage detector 10 receives the input by the test button 108 and transmits the operation confirmation information to the terminal device 20. Upon receiving the operation confirmation information, the terminal device 20 displays the wording "test OK" in the work result area 604 of the screen 662 as shown in FIG. 8 (b).

The supervisor who visually recognizes the wording "test OK" displayed on the screen 662 presses the approval button 605 in order to approve the completion of the work W3. In this case, the display screen transitions from screen 662 to screen 664. The wording "test operation is good" is displayed in the notification area 606 of the screen 664 shown in FIG. 8 (c). Further, in the progress status area 607, a check mark is superimposed and displayed on the wording “step 3”. This indicates that the work W3, which is the third work in the series of work, has been completed. When the supervisor confirms the update of the progress status, he presses the button 608. In this case, the user interface screen for the work W4 next to the work W3 is displayed.

9 and 10 are diagrams showing an example of a user interface screen relating to the fourth work W4 in the series of work. When the CPU 202 accepts the selection of the button 608 on the screen 664 (see FIG. 8C), the CPU 202 displays the screen 670 shown in FIG. 9A on the display 208. In the work content area 602 of the screen 670, the wording “4. Electroscope work” indicating the order of the work W4 and the outline of the work content is displayed. The order of each work W1 to W3 and the outline of the work contents are also displayed.

In the notification area 606 of the screen 670, the wording "Please detect the voltage" prompting the execution of the work W4 is displayed. Since the screen 670 is a screen in a state before the voltage detection target (for example, the distribution line 5) is detected by the voltage detector 10, nothing is displayed in the work result area 604 of the screen 670. Not.

Next, when the supervisor who visually recognizes the screen 670 gives an instruction for work W4 to the operator, the operator uses the voltage detector 10 to detect the power distribution line 5. When the distribution line 5 is not energized, the voltage detector 10 does not transmit the detection result to the terminal device 20, so that nothing is displayed in the work result area 604.

As a result, the supervisor determines that the distribution line 5 is not energized and presses the approval button 605 to approve the completion of the work W4. The display screen transitions from screen 670 to screen 680. The word "electroscope good" is displayed in the notification area 606 of the screen 680 shown in FIG. 9B. In the progress area 607, a check mark is superimposed and displayed on the wording "step 4". This indicates that work W4, which is the fourth (that is, the last) work in the series of work, has been completed.

Here, since the worker often continues to perform the voltage detection of another voltage detection object when the voltage detection of one voltage detection object is completed, the work W1 and W2 are completed (for example, the approval button is pressed). Operations W1 and W2 can be omitted as long as it is within a predetermined time (for example, 24 hours) after pressing). Therefore, in the present embodiment, when the button 608 is pressed on the screen 680, the words "step 3" and "step 4" are deleted, and the screen returns to the screen 660. This is in consideration of the worker performing the work W3 and W4 on another electroscope object.

On the other hand, when the distribution line 5 is energized, the voltage detector 10 transmits a detection result indicating that the distribution line 5 is energized to the terminal device 20. Upon receiving the detection result, the terminal device 20 displays the screen 690 of FIG. 10A. The word "live line" is displayed in the work result area 604 of the screen 690.

As a result, the supervisor determines that the distribution line 5 is energized and approves the completion of the work W4, so that the approval button 605 is pressed. The display screen transitions from screen 690 to screen 700. The wording "live-line operation, please power out" is displayed in the notification area 606 of the screen 700. In this case, in order to prompt the voltage detection again, the check mark indicating the completion is not displayed in the wording "step 4" in the progress status area 607. In addition, the wording for prompting the re-voltage detection may be further displayed in the notification area 606.

By displaying the user interface screen as described above, the supervisor can give appropriate instructions to the worker. In addition, it is possible to encourage the worker to work in an appropriate procedure. Furthermore, it is possible to check in real time whether or not the work is being executed in an appropriate order, the progress of the current work, and the like.

<Functional configuration>
FIG. 11 is a block diagram showing a functional configuration of the voltage detector 10 and the terminal device 20.

With reference to FIG. 11, the voltage detector 10 includes an operation confirmation unit 152, a detection unit 154, and a short-range wireless communication unit 156 as main functional configurations. These functions are mainly realized by the CPU 102. Note that some or all of these functional configurations may be realized by hardware.

The terminal device 20 includes a short-range wireless communication unit 252, a terminal input unit 254, a position information acquisition unit 256, a notification unit 260, a history information registration unit 262, an information communication unit 264, and a determination unit 270. .. These functions are mainly realized by the CPU 202. Note that some or all of these functional configurations may be realized by hardware.

The operation confirmation unit 152 of the voltage detector 10 confirms the soundness of the voltage detector 10 (specifically, the soundness of the internal circuit and the battery voltage) according to the instruction from the operator using the test button 108. The operation confirmation unit 152 confirms the soundness of the internal circuit and the battery voltage by detecting, for example, the voltage generated when the test button 108 is pressed. When the operation confirmation unit 152 can detect the voltage, the operation confirmation unit 152 provides the operation confirmation information indicating the soundness confirmation result of the voltage detector 10 (that is, the internal circuit and the battery voltage are normal) to the short-range wireless communication unit. Output to 156. On the other hand, if the operation confirmation unit 152 cannot detect the voltage, it determines that at least one of the internal circuit and the battery voltage is abnormal, and does not output the operation confirmation signal.

The detection unit 154 detects the energized state of the object to be detected (for example, the distribution line 5) and the known power source (for example, the voltage detector checker). When the detection unit 154 detects the energized state of the object to be detected or the known power source, the detection unit 154 outputs a detection result indicating the energized state (that is, the detection result of the detection unit 154) to the short-range wireless communication unit 156.

The short-range wireless communication unit 156 transmits the operation confirmation information and the detection result to the terminal device 20 via the communication interface 106.

The short-range wireless communication unit 252 of the terminal device 20 receives the operation confirmation information and the detection result via the communication interface 220.

The terminal input unit 254 receives various instruction inputs from the user (here, the supervisor) via the touch panel 206. Specifically, the terminal input unit 254 inputs completion information (for example, information indicating the pressing of the approval button 605) indicating the completion of the work for each of the series of operations W1 to W4 using the voltage detector 10. accept. The position information acquisition unit 256 acquires the position information of the terminal device 20.

The notification unit 260 notifies information about a series of operations W1 to W4 using the voltage detector 10. Specifically, the notification unit 260 causes the above-mentioned screens 600 to 700 to be displayed on the display 208.

The notification unit 260 notifies the work to be performed by the worker in the series of work W1 to W4. For example, the notification unit 260 causes the work content area 602 to display the content of the work W1 currently to be performed on the screens 610 to 630 relating to the work W1.

In addition, the notification unit 260 notifies the soundness confirmation result received from the voltage detector 10 as the work result of the soundness confirmation work of the voltage detector 10. For example, the notification unit 260 displays the word “test OK” in the work result area 604 as the confirmation result indicated by the operation confirmation information received from the voltage detector 10 on the screen 610. Further, the notification unit 260 notifies the detection result of the detection unit 154 received from the voltage detector 10 as the work result of the work of confirming the energized state of the voltage detection object. For example, the notification unit 260 displays the word “live line” in the work result area 604 as the detection result received from the voltage detector 10 on the screen 690.

Further, when the predetermined work in the series of works W1 to W4 is completed, the notification unit 260 notifies the work to be performed by the worker next to the predetermined work. For example, when the work W1 is completed (for example, when the approval button 605 or the button 608 is pressed), the notification unit 260 displays a screen 630 regarding the work W2 to be performed by the worker next to the work W1.

The history information registration unit 262 registers the history information of each of the series of operations. As shown in FIG. 5, the history information includes a user ID, a date and time, a voltage detector ID, a work ID, a work result, a position information, and approval information. Typically, the position information is the position information of the terminal device 20 when the approval button 605 is pressed by the supervisor.

The information communication unit 264 transmits the history information to the server 30. In addition, the information communication unit 264 may receive information indicating the contents of the history information database 500 stored in the server 30 according to the instruction from the supervisor.

In a certain aspect, the determination unit 270 determines whether or not the predetermined work is appropriately performed based on the location information in which the predetermined work should be performed in the series of operations and the current position information of the terminal device 20. to decide. The work W1 and W2 are the work to be performed at the place Pa, and the work W3 and W4 are the work to be performed at the site Pb. It is assumed that the location information of the site Pb and the location information of the location Pa are stored in advance in the memory 204 of the terminal device 20.

For example, when the approval button 605 for completing the work W1 is pressed on the screen 610, the determination unit 270 compares the position information of the site Pb where the work W3 should be performed with the current position information of the terminal device 20. When the current position information indicates a position within a predetermined range from the position information of the site Pb, the determination unit 270 determines that the work W3 has been performed at an appropriate place.

On the other hand, if the current position information does not indicate a position within a predetermined range from the position information of the site Pb, the determination unit 270 determines that the work W3 is not properly performed. In this way, when the predetermined work is not properly performed, the notification unit 260 notifies the warning information (for example, the wording "Please work in an appropriate place").

In another aspect, the determination unit 270 determines whether or not the predetermined work is properly performed based on the content of the predetermined work and the information received from the voltage detector 10. Here, it is assumed that the predetermined work is the work W1 and the screen 600 is displayed. When the information received from the voltage detector 10 is the operation confirmation information, the determination unit 270 determines that the received information appropriately indicates the work result of the work W1.

On the other hand, when the information received from the voltage detector 10 is the detection result by the detection unit 154 (that is, the information indicating the work result of the work W2 and W4), the determination unit 270 does not properly perform the work W1. (That is, the received information does not indicate the work result of work W1). In this way, when the predetermined work is not properly performed, the notification unit 260 notifies the warning information (for example, the wording "Please perform the appropriate work").

<Processing procedure>
FIG. 12 is a flowchart showing an example of the operation of the terminal device 20.

With reference to FIG. 12, the CPU 202 displays the contents of the work currently to be performed by the worker (hereinafter, also referred to as “current work”) on the display 208 (step S10). For example, when the current work is work W1, the CPU 202 displays the wording "1. Pre-use inspection (test)" or the wording "Please test" on the screen 600 shown in FIG. 6A.

The CPU 202 displays the work result of the current work based on the information received from the voltage detector 10 (for example, operation confirmation information, detection result, etc.) (step S12). For example, when the current work is work W1, the CPU 202 displays the wording “test OK” or the like on the screen 600 shown in FIG. 6 (b).

The CPU 202 determines whether or not the input of the approval instruction for the completion of the current work has been accepted via the approval button 605 (step S14). If the input of the approval instruction is not accepted (NO in step S14), the CPU 202 transmits the history information of the current work to the server 30 (step S15), and then the CPU 202 repeats the process of step S14. At this time, the CPU 202 also stores the history information in the memory 204.

On the other hand, when the input of the approval instruction is accepted (YES in step S14), the CPU 202 transmits the history information of the current work to the server 30 (step S16). At this time, the CPU 202 also stores the history information in the memory 204. Further, the CPU 202 may notify the warning information when it is determined that the current work is not appropriate.

Subsequently, the CPU 202 updates the progress of a series of operations (step S18). For example, when the current work is work W1, the CPU 202 superimposes and displays a check mark on the wording “step 1” of the progress area 607 of the screen 620 shown in FIG. 6 (c).

The CPU 202 determines whether or not all the series of operations have been completed (step S20). Specifically, the CPU 202 determines whether or not the work W4 has been completed. When all the series of operations are completed (YES in step S20), the CPU 202 ends the process. If all the series of operations are not completed (YES in step S20), the CPU 202 identifies the next operation of the current operation (step S22) and repeats the process from step S10.
