The car 6 has 1 or more on-car switches 13. In this example, a plurality of on-car switches 13 are provided. Each of the car-mounted switches 13 is disposed on an upper surface of the car 6 on the outer side, for example. Each on-car switch 13 is, for example, a safety switch. The plurality of on-car switches 13 include RUN-STOP switches for switching between operation and STOP, for example. The plurality of on-car switches 13 include, for example, AUTO-HAND switches for switching the operation mode between the automatic operation mode and the manual operation mode. The plurality of on-car switches 13 include, for example, a DOOR switch for switching the operation mode of the car DOOR 9.
The work support system 11 includes a 1 st light emitting unit 14, a 2 nd light emitting unit 15, a notification unit 16, and a work support device 17.
The 1 st light-emitting unit 14 is a portion that emits visible light. The 1 st Light Emitting unit 14 is, for example, an LED lighting device (LED). In this example, the 1 st light-emitting unit 14 is provided around the plurality of insertion ports 12 so as to surround the plurality of insertion ports 12.

The work assisting device 17 may be a device integrated with another device provided on the upper surface of the outside of the car 6. The work assisting apparatus 17 includes a communication unit 18, a situation determination unit 19, and a control unit 20.
The communication unit 18 is a part that communicates with a device outside the work assisting device 17. The devices outside the work assisting device 17 are, for example, the main body of the car 6 and the control panel 8. The communication unit 18 is connected to the control panel 8 through, for example, the trailing cable 10.
The situation determination unit 19 is a unit that determines the situation of the operation such as the maintenance spot inspection of the elevator 1. The work state includes the start of the operator getting above the car 6, the end of the work on the car, and the like. The state of work is determined based on, for example, the position of the car 6, the state of the landing doors 4 at each landing 3, the state of the devices connected to each insertion opening 12, and the state of the switches 13 on each car. The situation determination unit 19 has a function of acquiring a state in which the device is connected to each insertion port 12. The situation determination unit 19 has a function of acquiring the state of the switch 13 on each car. For example, before the start of the work on the car, the landing doors 4 of the landings 3 are closed after the locks 5 are locked. At this time, the situation determination unit 19 obtains information on the state of the landing door 4 of each landing 3, for example, via the control panel 8. The situation determination unit 19 determines that the operation on the car has not started based on the acquired information.
The control unit 20 is a part for controlling the 1 st light emitting unit 14, the 2 nd light emitting unit 15, the notification unit 16, and the like, according to the determination of the situation determination unit 19.

The control unit 20 is connected to each of the 1 st light emitting unit 14, the 2 nd light emitting unit 15, and the notification unit 16, and is capable of outputting a control signal for controlling the operation.
Next, an example of the operation on the car using the operation assisting system 11 will be described with reference to fig. 3 and 4.
Fig. 3 and 4 are diagrams illustrating an example of an operation on the car of the elevator according to embodiment 1.
As shown in fig. 3, the operator carries a moving lamp 21 for illuminating the operation range above the car 6, for example, to perform the car-up operation.
When starting the operation on the car, first, the operator unlocks the lock 5 of the landing door 4 at the landing 3 at a floor above the position where the car 6 is stopped. The operator opens the landing door 4 after unlocking the lock 5. The operator enters the car 6 from the landing 3 with the landing door 4 opened. Here, when the position at which the car 6 stops is a door region in an arbitrary floor, the landing door 4 of the landing 3 on a floor above the floor is a landing door 4 that does not correspond to the position at which the car 6 stops. In addition, when work is performed above the car 6, the car 6 may be stopped at a position other than the door region. In this case, the landing door 4 of each landing 3 is a landing door 4 that does not correspond to a position at which the car 6 stops.
When the landing door 4 that does not correspond to the position at which the car 6 is stopped is opened, the condition determining unit 19 of the work assisting apparatus 17 obtains the condition of the landing door 4, for example, via the control panel 8. The situation determination unit 19 determines whether or not the landing door 4 corresponding to a position at which the car 6 stops is the landing door 4 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 corresponding to the position at which the car 6 is not stopped is open, the situation determination unit 19 determines that the operator starts to enter above the car 6. The situation determination unit 19 outputs the determination result of starting to enter the upper side of the car 6 to the control unit 20.
The control unit 20 of the work assisting device 17 turns on the 1 st light emitting unit 14 and the 2 nd light emitting unit 15 in accordance with the determination result of the entry start input from the situation determination unit 19. The 1 st light emitting unit 14 illuminates each insertion slot 12. The 2 nd light emitting unit 15 illuminates each on-car switch 13.
The operator enters the car 6 from the landing 3 with the landing door 4 opened. 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 automatic operation mode to the manual operation mode by the AUTO-HAND switch.
Then, the operator connects the power cable of the portable lamp 21 to any of the insertion ports 12 illuminated by the 1 st light emitting unit 14.
As shown in fig. 4, the portable lamp 21 receives power supply through the insertion port 12 and illuminates the work area above the car 6.
The situation determination unit 19 determines that the power cable of the portable lamp 21 is connected to any of the insertion ports 12. The situation determination unit 19 outputs the determination result to the control unit 20. The controller 20 turns off the 1 st light emitting unit 14 according to the determination result input from the situation determination unit 19 and connected to the insertion port 12.
The situation determination unit 19 determines that the operator is present above the car 6 while at least one of the conditions that the landing door 4 not corresponding to the position at which the car 6 is stopped is open and the movable lamp 21 is connected to the insertion opening 12 is satisfied. The situation 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 lighting based on the determination result that the operator is present. In this example, when the landing door 4 and the like are closed once in the step of working on the car, the moving lamp 21 remains connected to the insertion port 12, and therefore the 2 nd light emitting unit 15 continues to be lit.
When the worker finishes the operation on the car, the power cable of the portable lamp 21 is pulled out from the insertion opening 12. The situation determination unit 19 determines that the connection between the power cable of the portable lamp 21 and the inlet 12 is released. The situation 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 according to the determination result of the connection release input from the situation determination unit 19. When the work on the car is completed, the landing doors 4 that do not correspond to the position at which the car 6 is stopped are 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 the operator is present above the car 6, the 2 nd light emitting unit 15 continues to be lit even after the movable lamp 21 is disconnected from the insertion port 12.
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, the situation determination unit 19 determines the operation of the on-car switch 13 when any on-car switch 13 is operated. When the situation determination unit 19 determines that any on-car switch 13 is operated while the operator is determined to be present above the car 6, the result of the determination of the operation of the on-car switch 13 is output 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 the result of determination of the operation of the on-car switch 13 that is input when the operator is present above the car 6.
Then, the operator descends from above the car 6 to the landing 3. The landing 3 where the operator is present closes the landing door 4. The operator locks the lock 5 of the closed landing door 4. The condition determination unit 19 obtains the state of the landing door 4, for example, via the control panel 8. When each landing door 4 is closed and the connection between the movable lamp 21 and the insertion opening 12 is released, the situation determination unit 19 determines that the operator has finished getting above the car 6. The situation determination unit 19 outputs the determination result of the completion of the entry into the upper side of the car 6 to the control unit 20. Control unit 20 turns off 1 st light emitting unit 14 and 2 nd light emitting unit 15 in accordance with the determination result of the entry completion input from situation determination unit 19. At this time, the operation on the car is ended.
Next, an example of the operation of the work assisting 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 the car 6 starts to move upward. If the determination result is "no", the operation of the work assistance system 11 proceeds to step S1 again. On the other hand, if the determination result is yes, the operation of the work assistance system 11 proceeds to step S2.
In step S2, control unit 20 causes 1 st light emitting unit 14 and 2 nd light emitting unit 15 to light up. Then, the operation of the work assistance system 11 proceeds to step S3.
In step S3, the situation determination unit 19 determines whether or not the portable lamp 21 is connected to any of the insertion ports 12. If the determination result is yes, the operation of the work assistance system 11 proceeds to step S4. On the other hand, if the determination result is "no", the operation of the work assistance system 11 proceeds to step S7.
In step S4, control unit 20 turns off 1 st light emitting unit 14. If light emission part 1 14 is already turned off, controller 20 may continue to turn off light emission part 1 14. Then, the operation of the work assistance system 11 proceeds to step S5.
In step S5, the situation determination unit 19 determines whether or not any on-car switch 13 has been operated. In this example, the situation determination unit 19 determines whether or not 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 assistance system 11 proceeds to step S3. On the other hand, if the determination result is yes, the operation of the work assistance 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 switching of the operation mode by sound. Then, the operation of the work assistance system 11 proceeds to step S3.
In step S7, the situation determination unit 19 determines whether or not each landing door 4 is closed. If the determination result is "no", the operation of the work assistance 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 entering the car 6. Then, the operation of the work assistance system 11 proceeds to step S9.
In step S8, control unit 20 turns on 1 st light emitting unit 14. If 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 assistance system 11 proceeds to step S5.
In step S9, control unit 20 turns off 1 st light emitting unit 14 and 2 nd light emitting unit 15. Then, the operation of the work support system 11 is ended.
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 a situation in which the car 6 starts to enter above. A 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 car 6 starts to enter the upper side, 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 assisting system 11 easily makes the operator notice the insertion port 12. Therefore, during the operation on the car, it is easy to confirm the position of the insertion port 12 to which the portable lamp 21 is connected in order to supply power to the portable lamp 21. This enables the operator to quickly illuminate the upper side of the car 6 by moving the lamp 21. Thus, the operator can quickly illuminate the upper side of the car 6 by moving the lamp 21, and thus the workability of the work on the car is not easily deteriorated. Further, since the 1 st light emitting unit 14 illuminates the insertion opening 12, even when the upper side of the car 6 is dark, the operator can easily visually recognize the insertion opening 12. Therefore, the operator does not need to hold the lamp or the like with the hand to find the insertion port 12. In this way, the operator is free of hands, and therefore, the workability of work on the car is not easily reduced even when the area above the car 6 is dark. In addition, in the elevator 1, a point inspection lamp that widely illuminates the work area above the car 6 is not installed, and therefore, the area above the car 6 may be dark. According to the work support system 11, the workability of the work on the car is not easily lowered in the elevator 1.
Further, the situation determination unit 19 determines that the car 6 has entered the upper side when the landing door 4 corresponding to the position at which the car 6 is not stopped among the plurality of landing doors 4 corresponding to the car 6 is opened. In the car-mounted work, an operator enters the car 6 from the landing 3 where the difference between the height of the floor of the landing 3 and the height of the outer upper surface of the car 6 is small. On the other hand, the floor height of the landing 3 where the landing door 4 corresponding to the position where the car 6 is stopped is the floor height of the stopped car 6. Therefore, during the operation on the car, the operator starts to enter above the car 6 by opening the landing door 4 that does not correspond to the position where the car 6 stops. Since the start of the entry is determined based on the natural procedure of the operation on the car, the operation efficiency of the operation on the car is not easily lowered. Further, since the landing doors 4 that do not correspond to the position at which the car 6 is stopped do not open during the normal operation, the situation determination unit 19 does not easily erroneously determine that entry is to be started during the normal operation.
Further, the 1 st light emitting unit 14 is provided so as to surround the insertion port 12. This improves the visibility of the insertion opening 12. Further, the operator can more clearly recognize the position of the insertion port 12.
When the portable lamp 21 is connected to the insertion port 12, the 1 st light emitting unit 14 is turned off. During the period when the portable lamp 21 is turned on, the operator does not need to recognize the insertion port 12 until the operation on the car is completed. In this case, power consumption due to unnecessary light emission of the 1 st light emitting unit 14 can be suppressed. When the movable lamp 21 is disconnected from the insertion port 12, the 1 st light emitting unit 14 is turned on. Even when the worker does not illuminate the work area by releasing the connection between the movable lamp 21 and the insertion port 12, the worker can easily confirm the position of the insertion port 12 again. Therefore, even when the connection between the portable lamp 21 and the insertion port 12 is temporarily released or when the connection between the portable lamp 21 and the insertion port 12 is erroneously released in a work step of the on-car work, the worker easily reconnects the portable 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 to illuminate the on-car switch 13 when the situation determination unit 19 determines that the car 6 starts to enter upward. 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 unit 15 is turned on, and thus the work assisting 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 prior to the lighting of the portable lamp 21. In this case, the operator can also quickly confirm the position of the on-car switch 13, and thus the workability of the on-car operation is not easily degraded. 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 light is dark above the car 6. Therefore, the operator does not need to hold the lamp or the like with the hand to find the on-car switch 13.
The 2 nd light emitting unit 15 is provided so as to surround the on-car switch 13. This improves the visibility of the on-car switch 13. Further, the operator can more clearly recognize the position of the switch 13 on the car.
Further, the 2 nd light emitting unit 15 is continuously lit during a period in which at least one of the conditions that the landing door 4, which does not correspond to the position at which the car 6 stops, among the plurality of landing doors 4 corresponding to the car 6 is opened and the moving lamp 21 is connected to the insertion opening 12 is satisfied. In a working step of working on the car, the landing door 4 may be temporarily opened and closed. In this case, the 2 nd light emitting unit 15 is continuously turned on while the portable lamp 21 is connected to the insertion port 12. Therefore, during the on-car work, the operator can easily confirm the state of the on-car switch 13 illuminated by the 2 nd light emitting unit 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 while the 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 any one of the conditions that the landing door 4 not corresponding to the position at which the car 6 is stopped is opened and the movable lamp 21 is connected to the insertion opening 12 is satisfied. This also notifies the operator who is located at a position above the car 6 from which the operator cannot visually recognize the switching of the operation mode. Therefore, if there is an operator who performs work at another place in parallel with the work on the car, the notification portion 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 operation mode that has been erroneously switched to the original mode.
Further, the situation determination unit 19 may determine that the landing door 4 corresponding to a position at which the car 6 is not stopped has entered the upper side of the car 6 when the lock 5 of the landing door 4 among the plurality of landing doors 4 corresponding to the car 6 is unlocked. In the on-car operation, the operator unlocks the lock 5 of the landing door 4 before opening the landing door 4 that does not correspond to the position at which the car 6 is stopped. Therefore, the start of the entry is determined based on the natural procedure of the operation on the car, and therefore, the operation efficiency of the operation on the car is not easily lowered. Further, since the lock 5 of the landing door 4 that does not correspond to the position at which the car 6 is stopped is not unlocked during normal operation, the situation determination unit 19 does not easily erroneously determine that entry is to be started during normal operation.
The 1 st light emitting unit 14 may be provided adjacent to the insertion port 12. The 2 nd light emitting unit 15 may be provided adjacent to the on-car switch 13. This improves visibility of the insertion port 12 and the on-car switch 13. The 1 st light-emitting unit 14 may be provided along a path from an end on the landing 3 side above the car 6 to the insertion opening 12. The 2 nd light emitting unit 15 may be provided along a path from an end on the landing 3 side above the car 6 to the on-car switch 13. The end on the landing 3 side above the car 6 is, for example, a portion above the car door 9. This makes it easy for the work support system 11 to guide the operator to the insertion port 12 or the on-car switch 13. Here, the path from the end on the landing 3 side above the car 6 may be, for example, a straight path having the shortest distance. Alternatively, the path from the end on the landing 3 side above the car 6 may be a zigzag path or a curved path. The 1 st light emitting part 14 or the 2 nd light emitting part 15 may be arranged in a dotted line or a broken line along a path from an end on the landing 3 side above the car 6.
Further, the 1 st light emitting unit 14 may be continuously lit while the landing door 4, which does not correspond to the position where the car 6 stops, among the plurality of landing doors 4 corresponding to the car 6 is open. In this case, the 2 nd light emitting unit 15 is continuously lit during the period in which the landing door 4 is open, regardless of the state in which the moving lamp 21 is connected to the insertion slot 12. Therefore, the operator can easily confirm the connection state of the portable lamp 21.
Further, after the connection between the portable lamp 21 and the insertion port 12 is released, the 2 nd light emitting unit 15 may be turned on for a predetermined time and then turned off. 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 moving lamp 21 is turned off. In this case, the lighting of the 2 nd light emitting unit 15 is maintained for a predetermined time, and thus the operator can quickly confirm the position of the switch 13 on the car, and thus the workability of the work on the car is not easily deteriorated.
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 assignment and the like between the plurality of cars 6.
For example, a 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, a part or all of the functions of the situation 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 according to embodiment 1.
Each function of the work support system 11 can be realized by a processing circuit. The processing circuit has at least 1 processor 200a and at least 1 memory 200b. The processing circuitry may also have at least 1 dedicated piece of hardware 100, either together with or instead of the processor 200a and the memory 200b.
Where the processing circuitry has a processor 200a and a memory 200b, the functions of the job assistance system 11 are implemented in 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 the program stored in the memory 200b, thereby realizing each function of the work assistance system 11.
The processor 200a is also called a CPU (Central Processing Unit), a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 200b is constituted by a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM.
In case the processing circuit has dedicated hardware 100, the processing circuit is for example implemented by a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA or a combination thereof.
Each function of the work support system 11 can be realized by a processing circuit. Alternatively, the functions of the work support system 11 may be realized by a processing circuit in a lump. The functions of the work support system 11 may be partially implemented by dedicated hardware 100 and partially implemented by software or firmware. In this way, the processing circuit implements the functions of the work assistance system 11 by dedicated hardware 100, software, firmware, or a combination thereof.
