The control unit 20 is connected to the 1 st light emitting unit 14, the 2 nd light emitting unit 15, and the notification unit 16, respectively, so as to be able to output a control signal for controlling the operation.
Next, an example of an on-car operation using the operation support system 11 will be described with reference to fig. 3 and 4.
Fig. 3 and 4 are diagrams showing examples of the work on the car of the elevator according to embodiment 1.
As shown in fig. 3, an operator performs an on-car operation by holding a moving lamp 21 for illuminating an operation range above the car 6, for example.
When starting the work on the car, first, the worker unlocks the lock 5 of the landing door 4 at the landing 3 at a floor above the position where the car 6 stops. The operator opens the landing door 4 after unlocking the lock 5. The operator enters from the landing 3 after opening the landing door 4 to above the car 6. Here, when the position at which the car 6 stops is a door zone in an arbitrary floor, the landing door 4 of the landing 3 of a floor above the floor is the landing door 4 that does not correspond to the position at which the car 6 stops. In addition, when working above the car 6, the car 6 may be stopped at a position other than the door area. In this case, the landing doors 4 of the respective landings 3 are landing doors 4 that do not correspond to the positions at which the car 6 stops.
When the landing door 4 not corresponding to the position where the car 6 stops is opened, the status determination unit 19 of the work support device 17 obtains the status of the landing door 4, for example, by the control panel 8. The situation determination unit 19 determines whether or not the landing door 4 is a landing door 4 that does not correspond to the position at which the car 6 stops, based on the position of the car 6 and the floor on which the opened landing door 4 is provided. When it is determined that the landing door 4 not corresponding to the position where the car 6 stops is opened, the situation determination unit 19 determines that the operator starts to enter above the car 6. The situation determination unit 19 outputs a determination result of starting to enter the upper part of the car 6 to the control unit 20.
The control unit 20 of the work support device 17 turns on the 1 st light emitting unit 14 and the 2 nd light emitting unit 15 based on the determination result of the start entry inputted from the situation determination unit 19. The 1 st light emitting unit 14 illuminates each insertion port 12. The 2 nd light emitting unit 15 illuminates each car upper switch 13.
The operator enters from the landing 3 after opening the landing door 4 to above the car 6. The operator operates the car switch 13 illuminated by the 2 nd light emitting unit 15. The operation performed here includes, for example, an operation of switching the operation mode from the automatic operation mode to the manual operation mode by the AUTO-HAND switch.
Then, the worker connects the power cable of the moving lamp 21 to the arbitrary insertion port 12 illuminated by the 1 st light emitting section 14.
As shown in fig. 4, the moving lamp 21 receives power supply through the insertion opening 12, and illuminates the working area above the car 6.
The situation determination unit 19 determines that the power cable of the mobile lamp 21 is connected to any of the insertion ports 12. The status determination unit 19 outputs the determination result to the control unit 20. The control unit 20 turns off the 1 st light emitting unit 14 based on the determination result of connection with the insertion port 12 input from the status determination unit 19.
The situation determination unit 19 determines that an operator is present above the car 6 during a period when at least one of the conditions of opening the landing door 4 and connecting the moving lamp 21 to the insertion port 12, which do not correspond to the position where the car 6 is stopped, is satisfied. The status determination unit 19 outputs the determination result to the control unit 20. The control unit 20 causes the 2 nd light emitting unit 15 to continue to be turned on based on the determination result of the presence of the operator. In this example, when the landing door 4 or the like is closed once in the step of working on the car, the moving lamp 21 is still connected to the insertion port 12, and therefore, the 2 nd light emitting unit 15 is also continuously turned on.
When the worker finishes working on the car, the worker pulls out the power cable of the moving lamp 21 from the insertion port 12. The situation determination unit 19 determines that the connection between the power cable of the moving lamp 21 and the insertion port 12 has been released. The status determination unit 19 outputs the determination result to the control unit 20. The control unit 20 turns on the 1 st light emitting unit 14 based on the connection release determination result input from the situation determination unit 19. When the work on the car is completed, the landing door 4 not corresponding to the position where the car 6 stops is opened so that the operator can descend from above the car 6 to the landing 3. At this time, since the situation determination unit 19 determines that an operator is present above the car 6, the 2 nd light emitting unit 15 is also continuously turned on after the connection between the moving lamp 21 and the insertion port 12 is released.
Then, the operator operates the on-car switch 13 illuminated by the 2 nd light emitting unit 15. The operation performed here includes, for example, an operation of switching the operation mode from the manual operation mode to the automatic operation mode by the AUTO-HAND switch. Here, when any of the on-car switches 13 is operated, the situation determination unit 19 determines the operation of the on-car switch 13. When it is determined that an operator is present above the car 6, the situation determination unit 19 outputs a determination result of the operation of the on-car switch 13 to the control unit 20. The control unit 20 causes the notification unit 16 to notify that the on-car switch 13 is operated, based on a determination result of the operation of the on-car switch 13 input when an operator is present above the car 6.
The operator then descends from above the car 6 to the landing 3. The operator closes the landing door 4 at the next landing 3. The operator locks the lock 5 of the closed landing door 4. The status determination unit 19 obtains the status of the landing door 4 via the control panel 8, for example. When each landing door 4 is closed and the connection between the moving lamp 21 and the insertion port 12 is released, the situation determination unit 19 determines that the operator has finished entering the upper side of the car 6. The situation determination unit 19 outputs a determination result of ending entering above the car 6 to the control unit 20. The control unit 20 turns off the 1 st light emitting unit 14 and the 2 nd light emitting unit 15 according to the determination result of the end entry input from the situation determination unit 19. At this time, the work on the car ends.
Next, an example of the operation of the work support system 11 will be described with reference to fig. 5.
Fig. 5 is a flowchart showing an example of the operation of the work support system according to embodiment 1.
In step S1, the situation determination unit 19 determines whether or not to start entering above the car 6. If the determination result is no, the operation of the work support system 11 proceeds again to step S1. On the other hand, when the determination result is yes, the operation of the work support system 11 proceeds to step S2.
In step S2, the control unit 20 turns on the 1 st light emitting unit 14 and the 2 nd light emitting unit 15. Then, the operation of the work support system 11 proceeds to step S3.
In step S3, the status determination unit 19 determines whether or not the moving lamp 21 is connected to any of the insertion ports 12. If the determination result is yes, the operation of the work support system 11 proceeds to step S4. On the other hand, if the determination result is no, the operation of the work support system 11 proceeds to step S7.
In step S4, the control unit 20 turns off the 1 st light emitting unit 14. When the 1 st light emitting unit 14 is turned off, the control unit 20 may continue to turn off the 1 st light emitting unit 14. Then, the operation of the work support system 11 proceeds to step S5.
In step S5, the situation determination unit 19 determines whether or not any operation of the on-car switch 13 has been performed. In this example, the situation determination unit 19 determines whether or not the AUTO-HAND switch is operated to switch the operation mode from the manual operation mode to the automatic operation mode. 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 is operated. In this example, the notification unit 16 notifies the switching of the operation mode by sound. Then, the operation of the work support system 11 proceeds to step S3.
In step S7, the status determination unit 19 determines whether or not each of the landing doors 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, when the determination result is yes, the situation determination unit 19 determines that the operator has finished entering the upper side of the car 6. Then, the operation of the work support system 11 proceeds to step S9.
In step S8, the control unit 20 turns on the 1 st light emitting unit 14. When the 1 st light emitting unit 14 is already turned on, the control unit 20 may continue to turn on the 1 st light emitting unit 14. Then, the operation of the work support system 11 proceeds to step S5.
In step S9, the control unit 20 turns off the 1 st light emitting unit 14 and the 2 nd light emitting unit 15. Then, the operation of the work support system 11 ends.
As described above, the work support system 11 according to embodiment 1 includes the situation determination unit 19 and the 1 st light emitting unit 14. The situation determination unit 19 determines that the situation starts to enter above the car 6. The moving lamp 21 for illuminating the upper side of the car 6 is connected to the insertion port 12 to receive power supply. When the situation determination unit 19 determines that the elevator car starts to enter the upper part of the car 6, the 1 st light emitting unit 14 is turned on to illuminate the insertion opening 12. The 1 st light emitting unit 14 is turned on, and thus the work support system 11 makes it easy for the operator to notice the insertion port 12. Therefore, during the work on the car, the position of the insertion opening 12 to which the moving lamp 21 is connected in order to supply power to the moving lamp 21 can be easily checked. This allows the operator to quickly illuminate the upper side of the car 6 by the moving lamp 21. In this way, the operator can quickly illuminate the upper part of the car 6 by the moving lamp 21, and therefore, the workability of the work on the car is not easily lowered. Further, since the 1 st light emitting unit 14 illuminates the insertion opening 12, the insertion opening 12 is easily visually recognized by the operator even when the upper part of the car 6 is dark. Therefore, the operator does not need to hold the lamp or the like with his hand in order to find the insertion port 12. In this way, the hands of the operator are left empty, and therefore, even when the upper part of the car 6 is dark, the workability of the work on the car is not easily lowered. In addition, since the spot lamp that widely illuminates the working area above the car 6 is not installed in the elevator 1, the area above the car 6 may be dark. According to the work support system 11, in this elevator 1, the workability of the work on the car is not easily lowered.
When the landing door 4 corresponding to the position where the car 6 is not stopped among the plurality of landing doors 4 corresponding to the car 6 is opened, the situation determination unit 19 determines that the car 6 is above. In the work on the car, the operator enters from the landing 3 where the difference between the height of the floor of the landing 3 and the height of the upper surface on the outside of the car 6 is small, to above the car 6. On the other hand, the floor surface of the landing 3 provided with the landing door 4 corresponding to the position where the car 6 stops is set to the floor surface of the stopped car 6. Therefore, during the work on the car, the operator starts to enter the upper side of the car 6 by opening the landing door 4 which does not correspond to the position where the car 6 stops. Since the start of entry is determined based on the natural procedure of the work on the car, the work efficiency of the work on the car is not easily lowered. Further, since the landing door 4 that does not correspond to the position where the car 6 stops is not opened in the normal operation, the situation determination unit 19 is not likely to erroneously determine that entry is started in the normal operation.
Further, the 1 st light emitting portion 14 is provided so as to surround the insertion port 12. This improves visibility of the insertion port 12. Further, the operator can more clearly recognize the position of the insertion port 12.
When the movable lamp 21 is connected to the insertion port 12, the 1 st light emitting unit 14 is turned off. The operator does not need to identify the insertion port 12 until the completion of the work on the car during the time when the moving lamp 21 is on. In this case, the power consumption due to unnecessary light emission of the 1 st light emitting unit 14 can be suppressed. When the connection between the movable lamp 21 and the insertion port 12 is released, the 1 st light emitting unit 14 is turned on. Even when the operation range is not illuminated by releasing the connection between the moving lamp 21 and the insertion port 12, the operator can easily check the position of the insertion port 12 again. Therefore, even when the connection between the moving lamp 21 and the insertion port 12 is temporarily released or when the connection between the moving lamp 21 and the insertion port 12 is erroneously released during the operation step of the car operation, the worker can easily reconnect the moving lamp 21 to the insertion port 12.
Further, the work support system 11 includes a 2 nd light emitting unit 15. The 2 nd light emitting unit 15 is turned on when the situation determination unit 19 determines that the car starts to enter above the car 6, and illuminates the car switch 13. The on-car switch 13 is a switch that is switched at the time of spot inspection above the car 6. The 2 nd light emitting portion 15 is turned on, whereby the work support system 11 makes it easy for the operator to notice 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 in preference to the lighting of the moving lamp 21. In this case, too, the operator can quickly check the position of the on-car switch 13, and therefore, the workability of the on-car work is not easily lowered. Further, since the 2 nd light emitting unit 15 illuminates the on-car switch 13, the operator can easily visually recognize the on-car switch 13 even when the upper part of the car 6 is dark. Therefore, the worker does not need to hold the lamp or the like with his hand in order to find the on-car switch 13.
Further, the 2 nd light emitting portion 15 is provided so as to surround the on-car switch 13. This improves visibility of the on-car switch 13. Further, the operator can more clearly recognize the position of the switch 13 on the car.
The 2 nd light emitting unit 15 is continuously turned on during a period when at least one of the conditions of opening the landing door 4 corresponding to a position where the car 6 does not stop and connecting the moving lamp 21 to the insertion port 12 is satisfied among the plurality of landing doors 4 corresponding to the car 6. In the working step of the car working, the landing door 4 may be temporarily opened and closed. In this case, the 2 nd light emitting unit 15 is continuously turned on during the period in which the movable lamp 21 is connected to the insertion port 12. Therefore, during the period of performing the on-car operation, the operator can easily check the state of the on-car switch 13 illuminated by the 2 nd light emitting portion 15.
The work support system 11 further includes a notification unit 16. When the on-car switch 13 is operated above the car 6 to switch the operation mode from the manual operation mode to the automatic operation mode during a period when an operator is present above the car 6, the notification unit 16 notifies the switching of the operation mode by sound. Here, whether or not an operator is present above the car 6 is determined based on whether or not at least one of the conditions of opening the landing door 4 and connecting the moving lamp 21 to the insertion port 12, which do not correspond to the position where the car 6 stops, is satisfied. This also notifies the operator located at a position above the car 6 that the operator cannot visually recognize the switching of the operation mode. Therefore, when there is an operator who performs work at another location in parallel with work on the car, the notification unit 16 can call the attention of the operator. In addition, even when the on-car switch 13 is erroneously operated, the switching of the operation mode is promptly notified to the operator. Therefore, the operator can quickly return the erroneously switched operation mode to the original mode.
Further, the situation determination unit 19 may determine that the elevator car 6 is above when the lock 5 of the landing door 4 corresponding to the position where the elevator car 6 is not stopped is released from among the plurality of landing doors 4 corresponding to the elevator car 6. In the work on the car, the worker 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 stops. Therefore, since the start of entry is determined based on the natural procedure of the work on the car, the work efficiency of the work on the car is not easily lowered. Further, since the lock 5 of the landing door 4, which does not correspond to the position where the car 6 stops, is not unlocked in the normal operation, the situation determination unit 19 is not likely to erroneously determine that entry is started in the normal operation.
The 1 st light emitting unit 14 may be provided adjacent to the insertion port 12. The 2 nd light emitting portion 15 may be provided adjacent to the car upper switch 13. This improves visibility of the insertion opening 12 and the on-car switch 13. The 1 st light emitting unit 14 may be provided along a path from an end of the car 6 on the landing 3 side to the insertion port 12. The 2 nd light emitting unit 15 may be provided along a path from an end of the car 6 above the landing 3 side to the car switch 13. The end of the landing 3 above the car 6 is, for example, a portion above the car door 9. Thus, the work support system 11 easily guides the operator to pay attention to the insertion opening 12 or the on-car switch 13. Here, the route from the end of the landing 3 above the car 6 may be, for example, a straight route having the shortest distance. Alternatively, the path from the end of the landing 3 above the car 6 may be a curved path or a bent path. A plurality of 1 st light emitting units 14 or 2 nd light emitting units 15 may be arranged in a stippled line or a broken line along a path from an end portion on the landing 3 side above the car 6.
Further, the 1 st light emitting unit 14 may be continuously turned on during a period in which the landing door 4 corresponding to a position where the car 6 is not stopped is opened, among the plurality of landing doors 4 corresponding to the car 6. In this case, the 2 nd light emitting unit 15 is continuously turned on during the period when the landing door 4 is opened, regardless of the state where the moving lamp 21 is connected to the insertion port 12. Therefore, the operator can easily confirm the connection state of the moving lamp 21.
Further, the 2 nd light emitting unit 15 may be turned on for a predetermined time after the connection between the movable lamp 21 and the insertion port 12 is released. For example, in the case where the on-car switch 13 is a safety switch or the like, the on-car switch 13 may be operated after the traveling lamp 21 is turned off. In this case, since the lighting of the 2 nd light emitting portion 15 is maintained for a predetermined time, the operator can quickly check the position of the on-car switch 13, and thus the workability of the on-car work is not easily lowered.
The elevator 1 may have a plurality of cars 6. In this case, the elevator 1 may have a group management device that performs call allocation or the like among the plurality of cars 6.
For example, part or all of the functions of the work support system 11 such as the communication unit 18, the situation determination unit 19, and the control unit 20 may be mounted on hardware such as the control panel 8, the group management device, or other devices of the elevator 1. For example, part or all of the functions of the status determination unit 19 may be mounted on the control panel 8.
Next, an example of the hardware configuration of the work support system 11 will be described with reference to fig. 6.
Fig. 6 is a hardware configuration diagram of a main part of the work support system of embodiment 1.

The processing circuitry may also have at least 1 dedicated hardware 100 in addition to or in lieu of the processor 200a and memory 200b.
In the case of a processing circuit having a processor 200a and a memory 200b, each function of the work support system 11 is implemented by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 200b. The processor 200a reads out and executes a program stored in the memory 200b, thereby realizing the functions of the work support system 11.
The processor 200a is also called a CPU (Central Processing Unit: central processing unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, a DSP. The memory 200b is constituted by a nonvolatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, or the like, for example.
In the case of processing circuitry having dedicated hardware 100, the processing circuitry is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.
The functions of the work support system 11 can be realized by a processing circuit. Alternatively, the functions of the work support system 11 can be realized by a processing circuit. Regarding the functions of the work support system 11, one part may be implemented by dedicated hardware 100, and the other part may be implemented by software or firmware. Thus, the processing circuitry implements the functions of the work support system 11 via dedicated hardware 100, software, firmware, or a combination thereof.
