Next, an example of on-car work using the work support system 11 will be described with reference to FIGS. 3 and 4. FIG.
3 and 4 are diagrams showing an example of work on the elevator car according to Embodiment 1. FIG.

As shown in FIG. 3, the worker carries, for example, a moving light 21 onto the car 6 to illuminate the work area and performs work on the car.

When starting work on the car, first, the worker unlocks the lock 5 of the landing door 4 in the landing 3 on the floor above the position where the car 6 is stopped. A worker opens the landing door 4 from which the lock 5 has been removed. A worker gets on the car 6 from the landing 3 with the landing door 4 opened. Here, when the position where the car 6 is stopped is the door zone on any floor, the landing door 4 of the landing 3 on the floor above that floor is positioned at the position where the car 6 is stopped. It is the landing door 4 that does not correspond. Incidentally, when the work is performed on the car 6, the car 6 may be stopped at a position other than the door zone. In this case, the landing door 4 of each landing 3 is the landing door 4 that does not correspond to the position where the car 6 is stopped.

When the landing door 4 that does not correspond to the position where the car 6 is stopped is opened, the situation determination unit 19 of the work support device 17 acquires the state of the landing door 4 through the control panel 8, for example. The situation determination unit 19 determines, based on the position of the car 6 and the floor on which the open landing door 4 is provided, that the landing door 4 is a landing door 4 that does not correspond to the position where the car 6 is stopped. determine whether When determining that the landing door 4 that does not correspond to the position where the car 6 is stopped is open, the situation determination unit 19 determines that the operator has started to board the car 6 . The situation determination unit 19 outputs to the control unit 20 the determination result of the start of boarding of the car 6 .

The control unit 20 of the work support device 17 lights the first light emitting unit 14 and the second light emitting unit 15 based on the determination result of the boarding start input from the situation determination unit 19 . The first light emitter 14 illuminates each receptacle 12 . The second light emitter 15 illuminates each on-car switch 13 .

A worker gets on the car 6 from the landing 3 with the landing door 4 opened. The operator operates the on-car switch 13 illuminated by the second light emitting section 15 . The operation performed here includes, for example, the operation of switching the operation mode from the automatic operation mode to the manual operation mode using the AUTO-HAND switch.

After that, the worker connects the power cable of the moving light 21 to one of the receptacles 12 illuminated by the first light emitting section 14 .

As shown in FIG. 4, the moving light 21 receives power through the receptacle 12 to illuminate the working area above the car 6. As shown in FIG.

The status determination unit 19 determines that the power cable of the moving light 21 has been connected to one of the receptacles 12 . The situation determination section 19 outputs the determination result to the control section 20 . The control unit 20 turns off the first light emitting unit 14 based on the determination result of the connection to the receptacle 12 input from the situation determination unit 19 .

The situation determination unit 19 determines whether at least one of the following conditions is satisfied: the landing door 4 that does not correspond to the position where the car 6 is stopped is open, or the moving light 21 is connected to the insertion port 12. Determine that there is an operator on the car 6 while it is full. The situation determination section 19 outputs the determination result to the control section 20 . The control unit 20 continuously lights the second light emitting unit 15 based on the determination result that the worker is present. In this example, even if the landing door 4 or the like is closed once in the procedure of the work on the car, since the moving light 21 is connected to the insertion port 12, the second light emitting part 15 is continuously lit. do.

The worker pulls out the power cable of the moving light 21 from the insertion port 12 when finishing the work on the car. The status determination unit 19 determines that the connection between the power cable of the moving light 21 and the receptacle 12 has been released. The situation determination section 19 outputs the determination result to the control section 20 . The control unit 20 causes the first light emitting unit 14 to light up based on the disconnection determination result input from the situation determination unit 19 . At the end of the work on the car, the landing door 4 that does not correspond to the position where the car 6 is stopped is opened so that the worker can get off the car 6 to the landing 3. At this time, since the situation determination unit 19 determines that the worker is on top of the car 6, the second light emission unit 15 continues even after the connection between the moving light 21 and the insertion port 12 is released. to light up.

After that, the worker operates the on-car switch 13 illuminated by the second light emitting section 15 . The operation performed here includes, for example, the operation of switching the operation mode from the manual operation mode to the automatic operation mode using the AUTO-HAND switch. Here, when one of the on-car switches 13 is operated, the situation determination unit 19 determines whether the on-car switch 13 is operated. When the status determination unit 19 determines that any of the car top switches 13 is operated while determining that the worker is on the car 6, the situation determination unit 19 outputs the determination result of the operation of the car top switch 13 to the control unit 20. output to The control part 20 makes the notification part 16 notify that the upper car switch 13 is operated based on the judgment result of the operation of the upper car switch 13 input when the worker is on the car 6. - 特許庁

After that, the worker gets off from the top of the car 6 to the landing 3 . The worker closes the landing door 4 at the landing 3 where he got off. A worker locks the lock 5 of the closed landing door 4. - 特許庁The situation determination unit 19 acquires the state of the hall door 4 through the control panel 8, for example. The situation determination unit 19 determines whether the operator has boarded the car 6 when all the landing doors 4 are closed and the connection between the moving light 21 and the insertion port 12 is released. determine the end of The situation determination unit 19 outputs to the control unit 20 the determination result of completion of boarding of the car 6 . The control unit 20 turns off the first light emitting unit 14 and the second light emitting unit 15 based on the determination result of the end of boarding input from the situation determination unit 19 . At this time, the work on the car ends.

Next, an example of operation of the work support system 11 will be described with reference to FIG.
5 is a flowchart showing an example of the operation of the work support system according to Embodiment 1. FIG.

In step S<b>1 , the situation determination unit 19 determines whether boarding onto the car 6 has started. If the determination result is No, the operation of the work support system 11 proceeds to step S1 again. On the other hand, when the determination result is Yes, the operation of the work support system 11 proceeds to step S2.

In step S<b>2 , the control unit 20 turns on the first light emitting unit 14 and the second light emitting unit 15 . After that, the operation of the work support system 11 proceeds to step S3.

In step S<b>3 , the status determination unit 19 determines to which of the insertion ports 12 the moving light 21 is connected. If the determination result is Yes, the operation of the work support system 11 proceeds to step S4. On the other hand, when the determination result is No, the operation of the work support system 11 proceeds to step S7.

In step S<b>4 , the control unit 20 turns off the first light emitting unit 14 . When the first light emitting unit 14 has already been turned off, the control unit 20 may continue turning off the first light emitting unit 14 . After that, the operation of the work support system 11 proceeds to step S5.

In step S5, the situation determination unit 19 determines whether any one of the on-car switches 13 has been operated. In this example, the situation determination unit 19 determines whether the AUTO-HAND switch for switching the operation mode from the manual operation mode to the automatic operation mode has been operated. If the determination result is No, the operation of the work support system 11 proceeds to step S3. On the other hand, when the determination result is Yes, the operation of the work support system 11 proceeds to step S6.

In step S6, the control unit 20 causes the notification unit 16 to notify that the on-car switch 13 has been operated. In this example, the notification unit 16 notifies the switching of the driving mode by voice. After that, the operation of the work support system 11 proceeds to step S3.

In step S7, the situation determination unit 19 determines whether each landing door 4 is closed. If the determination result is No, the operation of the work support system 11 proceeds to step S8. On the other hand, if the determination result is Yes, the situation determination unit 19 determines that the operator has finished getting on the car 6 . After that, the operation of the work support system 11 proceeds to step S9.

In step S<b>8 , the control section 20 turns on the first light emitting section 14 . When the first light emitting unit 14 has already been lit, the control unit 20 may cause the first light emitting unit 14 to continue lighting. After that, the operation of the work support system 11 proceeds to step S5.

In step S<b>9 , the control unit 20 turns off the first light emitting unit 14 and the second light emitting unit 15 . After that, the operation of the work support system 11 ends.

As described above, work support system 11 according to Embodiment 1 includes situation determination unit 19 and first light emitting unit 14 . The situation determination unit 19 determines the start of boarding of the car 6 . A moving light 21 that illuminates the top of the car 6 is connected to the receptacle 12 for receiving power. The first light emitting unit 14 lights up to illuminate the insertion port 12 when the situation determination unit 19 determines that the passenger should start getting into the car 6 . Lighting of the first light emitting unit 14 makes it easier for the work support system 11 to direct the worker's attention to the receptacle 12 . Therefore, it becomes easy to confirm the position of the insertion port 12 to which the moving light 21 is connected in order to supply electric power to the moving light 21 during work on the car. As a result, the worker can quickly illuminate the top of the car 6 with the moving light 21 . In this way, the worker can quickly brighten the top of the car 6 by the moving light 21, so that the workability of the work on the car is less likely to deteriorate. Further, since the first light emitting part 14 illuminates the insertion port 12, the operator can easily see the insertion port 12 even when the top of the car 6 is dark. Therefore, the worker does not need to hold a light or the like to find the receptacle 12. - 特許庁Since the worker's hands are freed in this manner, the workability of the work on the car 6 is less likely to deteriorate even when the top of the car 6 is dark. In addition, since the elevator 1 is not equipped with an inspection light that widely illuminates the working range above the car 6, the area above the car 6 may be dark. According to the work support system 11, even in such an elevator 1, the workability of the work on the car is less likely to deteriorate.

Further, the situation determination unit 19 discourages boarding onto the car 6 when the landing door 4 not corresponding to the position where the car 6 is stopped among the plurality of landing doors 4 corresponding to the car 6 opens. judge. In the work on the car, the worker gets on the car 6 from the landing 3 where the difference between the height of the floor surface of the landing 3 and the height of the upper surface of the outside of the car 6 is small. On the other hand, the height of the floor surface of the landing 3 provided with the landing door 4 corresponding to the position where the car 6 is stopped is the height of the floor surface of the stopped car 6 . Therefore, in the work on the car, the worker starts to get on the car 6 by opening the landing door 4 that does not correspond to the position where the car 6 is stopped. Since the start of boarding is determined according to the natural procedure of the work on the car, the working efficiency of the work on the car is less likely to decrease. In addition, since the landing door 4 that does not correspond to the position where the car 6 is stopped is not opened during normal operation, the situation determination unit 19 is less likely to erroneously determine that boarding has started during normal operation.

Also, the first light emitting unit 14 is provided so as to surround the insertion port 12 . Thereby, the visibility of the receptacle 12 is improved. Also, the operator can more clearly recognize the position of the receptacle 12 .

Also, the first light emitting unit 14 is turned off when the moving light 21 is connected to the insertion port 12 . While the moving light 21 is on, the worker does not need to recognize the insertion port 12 until the work on the car is finished. In this case, power consumption due to unnecessary light emission of the first light emitting unit 14 can be suppressed. Also, the first light emitting unit 14 lights up when the connection between the moving light 21 and the insertion port 12 is released. Even when the working range is no longer illuminated due to the disconnection between the moving light 21 and the insertion port 12, the worker can easily reconfirm the position of the insertion port 12.例文帳に追加For this reason, even when the connection between the moving light 21 and the insertion port 12 is temporarily released in the work procedure of the work on the car, or when the connection between the moving light 21 and the insertion port 12 is erroneously released, The operator can easily reconnect the mobile light 21 to the receptacle 12 .

The work support system 11 also includes a second light emitting unit 15 . The second light emitting unit 15 lights up to illuminate the on-car switch 13 when the situation determination unit 19 determines that the passenger should start getting into the car 6 . The on-car switch 13 is a switch that is switched during inspection on the car 6 . Lighting of the second light emitting unit 15 makes it easier for the work support system 11 to direct the worker's attention to the on-car switch 13 . For example, when the on-car switch 13 is a safety switch or the like, the on-car switch 13 may be operated with priority over the lighting of the moving light 21 . Even in such a case, since the operator can quickly confirm the position of the on-car switch 13, the workability of the on-car work is less likely to deteriorate. Further, since the second light-emitting portion 15 illuminates the on-car switch 13, the operator can easily see the on-car switch 13 even when the top of the car 6 is dark. Therefore, the operator does not need to hold a light or the like to search for the on-car switch 13 .

Further, the second light emitting portion 15 is provided so as to surround the on-car switch 13 . Thereby, the visibility of the on-car switch 13 is improved. Also, the operator can more clearly recognize the position of the on-car switch 13 .

Further, the second light emitting unit 15 detects whether the landing door 4 not corresponding to the position where the car 6 is stopped among the plurality of landing doors 4 corresponding to the car 6 is open, or the moving light 21 is inserted. It remains lit as long as it is connected to port 12 and/or is met. In the work procedure of work on the car, the landing door 4 may be temporarily opened and closed. Even in such a case, while the moving light 21 is connected to the insertion port 12, the second light emitting section 15 continues to light. This makes it easier for the worker to check the state of the on-car switch 13 illuminated by the second light-emitting portion 15 while the work on the car is being performed.

The work support system 11 also includes a notification unit 16 . When the on-car switch 13 is operated to switch the operation mode from the manual operation mode to the automatic operation mode on the car 6 while the worker is on the car 6, the notification unit 16 indicates the operation mode. The switching is notified by voice. Here, whether there is a worker on top of the car 6 is determined by whether the landing door 4 that does not correspond to the position where the car 6 is stopped is open, or whether the moving light 21 is connected to the insertion port 12. , is satisfied based on whether at least one of the conditions is satisfied. As a result, even a worker who is in a position where he cannot see the top of the car 6 is notified of the switching of the operation mode. Therefore, in the case where there is a worker who is working at another place in parallel with the work on the car, the notification unit 16 can alert the worker. Also, even if the on-car switch 13 is erroneously operated, the operator is promptly notified of the switching of the operation mode. For this reason, the operator can quickly restore the operation mode that has been erroneously switched.

In addition, the situation determination unit 19 determines that when the lock 5 of the landing door 4 that does not correspond to the position where the car 6 is stopped among the plurality of landing doors 4 corresponding to the car 6 is unlocked, You may judge boarding to. In the work on the car, the operator unlocks the lock 5 of the landing door 4 before opening the landing door 4 that does not correspond to the position where the car 6 is stopped. Therefore, the start of boarding is determined according to the natural procedure of the work on the car, so that the working efficiency of the work on the car is less likely to decrease. In addition, since the lock 5 of the landing door 4 that does not correspond to the position where the car 6 is stopped is not removed during normal operation, the situation determination unit 19 is less likely to erroneously determine the start of boarding during normal operation.

Also, the first light emitting unit 14 may be provided adjacent to the insertion port 12 . The second light emitting unit 15 may be provided adjacent to the on-car switch 13 . Thereby, the visibility of the insertion port 12 and the on-car switch 13 is improved.
