Embodiment 1 FIG.
FIG. 1 is a diagram illustrating an example of an elevator device according to the first embodiment. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down the hoistway 3. The counterweight 2 moves up and down the hoistway 3. The car 1 and the counterweight 2 are suspended from the hoistway 3 by the main rope 4.

  The main rope 4 is wound around a drive sheave 6 of a hoisting machine 5. The car 1 moves according to the rotation of the drive sheave 6. That is, the car 1 is driven by the hoisting machine 5. The hoisting machine 5 is controlled by the control device 7. FIG. 1 shows an example in which a hoisting machine 5 and a control device 7 are installed in a machine room 8 above a hoistway 3. The hoist 5 and the control device 7 may be installed in the hoistway 3. When the hoisting machine 5 is installed on the hoistway 3, the hoisting machine 5 may be installed on the top of the hoistway 3 or may be installed on a pit of the hoistway 3.

  FIG. 1 shows an example in which a thermometer 9 is provided in the hoisting machine 5. The thermometer 9 measures the temperature of the hoist 5. Information on the temperature measured by the thermometer 9 is input to the control device 7. The thermometer 9 may have a function of measuring humidity. That is, the elevator device may include a thermo-hygrometer.

  The car 1 includes an operation panel 10, a microphone 11, a vibration sensor 12, and a camera 13. The operation panel 10 is a device for a person riding on the car 1 to input information. For example, the operation panel 10 includes a destination button, an open button, and a close button. Information input from the operation panel 10 is input to the control device 7. In the control device 7, the call is registered based on the information input from the operation panel 10.

  The microphone 11 may be a part of an interphone provided in the operation panel 10. The sound information acquired by the microphone 11 is input to the control device 7. The vibration sensor 12 detects vibration. The vibration information acquired by the vibration sensor 12 is input to the control device 7. The camera 13 photographs the inside of the car 1. Information on the video image captured by the camera 13 is input to the control device 7. The car 1 may include only one of the microphone 11 and the vibration sensor 12.

  The car 1 further includes a door 14 and an electric motor 15. An entrance formed in the car 1 is opened and closed by a door 14. The door 14 is driven by an electric motor 15. The electric motor 15 is controlled by the control device 7. Further, a door 17 is provided in the hall 16 where the car 1 stops. The landing 16 is not provided with a device for driving the door 17. When the car 1 stops at the landing 16, the door 14 faces the door 17. The door 17 is driven by the electric motor 15 via the door 14.

  The car 1 further includes a weighing device 18. The weighing device 18 detects the load on the car 1. Information on the load detected by the weighing device 18 is input to the control device 7. The weighing device 18 is an example of a unit that detects a load on the car 1. As another example, a similar detecting means may be provided at the end of the main rope 4.

  The mobile terminal 19 is a terminal carried by a maintenance person of the elevator. The mobile terminal 19 is connected to the control device 7 by wire or wirelessly. The mobile terminal 19 is, for example, a smartphone. The mobile terminal 19 may be a PC-type terminal. The mobile terminal 19 may be a dedicated terminal used for maintenance of the elevator device.

  FIG. 2 is a diagram for explaining functions of the elevator device. The control device 7 includes, for example, a storage unit 20, a storage unit 21, a storage unit 22, a traveling control unit 23, a determination unit 24, a period setting unit 25, and a storage unit 26.

  The storage unit 20 stores the sound information acquired by the microphone 11. Information indicating the traveling state of the car 1 is stored in the storage unit 20. Hereinafter, the information indicating the traveling state of the car 1 is also referred to as “state information”. In the present embodiment, “running of car 1” includes an operation necessary for carrying the user by car 1. For this reason, the “running of the car 1” includes the opening / closing operation of the door 14 performed at the landing 16. As an example, the state information includes information indicating the departure floor of the car 1, information indicating the arrival floor of the car 1, and information indicating the load detected by the weighing device 18. As another example, the state information includes information indicating the speed of the car 1 and information indicating the position of the car 1. The sound information acquired by the microphone 11 is stored in the storage unit 20 in association with the state information acquired at the same time.

  The storage of the sound information and the state information in the storage unit 20 may be always performed. If the storage unit 20 is a ring buffer, the sound information and the status information acquired at a specific time are thereafter stored in the storage unit 20 for a certain period. The storage of the sound information and the state information in the storage unit 20 may be performed only when the car 1 is traveling.

  The running conditions of the car 1 are stored in the storage unit 21. The running conditions stored in the storage unit 21 are used to move or copy a part of the information stored in the storage unit 20 to the storage unit 22. The driving conditions are set in advance.

  Hereinafter, the functions of the elevator apparatus will be described in detail with reference to FIGS. FIG. 3 is a flowchart illustrating an operation example of the control device 7.

  The traveling control unit 23 controls traveling of the car 1 (S101). For example, the traveling control unit 23 stops the car 1 at the landing 16 on the departure floor where the user waits. The departure floor is the floor where the landing 16 where the landing button (not shown) is pressed. The traveling control unit 23 opens and closes the door 14 on the departure floor. When the door 14 is closed on the departure floor, the traveling control unit 23 moves the car 1 to the arrival floor. The arrival floor is synonymous with the destination floor of the user. The traveling control unit 23 opens and closes the door 14 on the arrival floor.

  At least while the car 1 is running, the sound information acquired by the microphone 11 is stored in the storage unit 20 in association with the state information (S102). As described above, the sound information and the state information may always be stored in the storage unit 20 regardless of whether the car 1 is running.

  FIG. 4 is a flowchart illustrating another operation example of the control device 7. The operation flow illustrated in FIG. 4 is performed in parallel with the operation flow illustrated in FIG. The control device 7 determines whether or not the traveling condition of the car 1 is set (S201). If the driving condition is stored in the storage unit 21, it is determined as Yes in S201. If the driving condition is not stored in the storage unit 21, it is determined as No in S201.

  For example, immediately after the elevator device is installed in the building, the traveling conditions are not stored in the storage unit 21. Consider an example in which a user hears an unfamiliar sound while moving in car 1. Unless the sound heard by the user is a loud sound that is determined to be abnormal, no abnormality log is left in the elevator device. In such a case, the maintenance person receiving the notification from the user inputs the condition from the mobile terminal 19 and stores the input condition in the storage unit 22 as the traveling condition of the car 1. Hereinafter, an example in which the traveling conditions of the car 1 are set from the mobile terminal 19 will be described.

  As shown in FIG. 2, the mobile terminal 19 includes a display 30, an input device 31, a condition setting unit 32, and a display control unit 33. The input device 31 is a device for the maintenance staff to input information. The mobile terminal 19 may include a touch panel type input device 31. The mobile terminal 19 may include a keyboard and a mouse as the input device 31.

  FIG. 5 is a flowchart illustrating an operation example of the mobile terminal 19. For example, when a specific operation is performed on the input device 31, the display control unit 33 displays a setting screen for setting conditions on the display 30 (S301). The condition setting unit 32 determines whether a condition has been input from the setting screen of the display 30 (S302).

  The maintenance staff operates the input device 31 and inputs conditions from the setting screen. For example, the maintenance staff inputs the departure floor of the car 1. The maintenance person inputs the arrival floor of the car 1. The maintenance person inputs the load range of the car 1. Only the lower limit may be input as the range of the load on the car 1. For example, “60 kg or more” is input as the range of the load of the car 1. When the maintenance staff presses an input completion button (not shown), the determination is Yes in S302. If it is determined as Yes in S302, the condition setting unit 32 transmits the condition input from the input device 31 to the control device 7 (S303).

  In the control device 7, the condition input from the input device 31 is stored in the storage unit 21 as the traveling condition. Hereinafter, an example in which the departure floor of the car 1, the arrival floor of the car 1, and the load range of the car 1 are set as the traveling conditions will be described.

  If it is determined as Yes in S201, the determination unit 24 determines whether or not the current traveling of the car 1 satisfies the traveling conditions based on the state information stored in the storage unit 20. For example, the determination unit 24 determines whether or not the current floor, that is, the floor where the car 1 is currently located, matches the departure floor set as the traveling condition (S202). If the determination is Yes in S202, the determination unit 24 determines whether the load of the car 1 detected by the weighing device 18 falls within the range of the load set as the traveling condition. If only the lower limit of the load is set as the traveling condition, the determination unit 24 determines whether the load of the car 1 detected by the weighing device 18 is larger than the lower limit (S203).

  In the example shown in the present embodiment, the traveling condition includes the initial condition. The initial condition is a condition under which the current travel of the car 1 can be determined to be satisfied before the car 1 starts moving. The determinations in S202 and S203 are for the initial conditions. That is, the determination unit 24 determines whether the traveling of the car 1 satisfies the initial conditions before the car 1 starts moving in S202 and S203. If the initial conditions are satisfied, it is determined as Yes in S203.

  The period setting unit 25 sets a period during which the acquired information is stored in the storage unit 22. Hereinafter, the above period is referred to as a storage target period. That is, the period setting unit 25 sets the storage target period. FIG. 6 is a diagram for explaining the function of the period setting unit 25. FIG. 6 shows an example of information stored in the storage unit 20. When the determination is Yes in S203, the period setting unit 25 sets a trigger 0 indicating that the initial condition is satisfied (S204). Next, the period setting unit 25 sets the trigger 1 that is the start of the storage target period (S205). FIG. 6 shows an example in which the trigger 1 is set such that the state information indicating the previous run performed by the car 1 is included in the storage target period.

  Next, the determination unit 24 determines whether the car 1 has started moving (S206). If the determination is Yes in S206, the determination unit 24 determines whether the car 1 has stopped (S207). When the determination is Yes in S207, the determination unit 24 determines whether or not the floor where the car 1 is present matches the arrival floor set as the traveling condition (S208). If No is determined in S208, the period setting unit 25 discards the trigger 0 set in S204 and the trigger 1 set in S205 (S209).

  When the determination is Yes in S208, the traveling condition is satisfied. When it is determined Yes in S208, the period setting unit 25 sets a trigger 2 that ends the storage target period (S210). The period from the trigger 1 set in S205 to the trigger 2 set in S210 is the storage target period. The storage unit 26 stores, in the storage unit 22, the state information and the sound information obtained during the storage target period among the information stored in the storage unit 20 (S211). Thereafter, the period setting unit 25 discards the trigger 0 set in S204, the trigger 1 set in S205, and the trigger 2 set in S210 (S212).

  The elevator maintenance staff can check the information stored in the storage unit 22 on the mobile terminal 19. FIG. 7 is a flowchart illustrating another operation example of the mobile terminal 19. When a specific operation is performed on the input device 31, the display control unit 33 acquires information stored in the storage unit 22 from the control device 7 (S401). The display control unit 33 displays the state information and the sound information stored in the storage unit 22 on the display 30 (S402).

  In the example shown in the present embodiment, of the information stored in the storage unit 20, state information indicating a running state determined to satisfy the running condition and sound information associated with the state information are stored in the storage unit 20. 22. Since the running conditions are set in accordance with the running when the user hears the abnormal noise, there is a high possibility that the cause of the noise can be specified from the information stored in the storage unit 22. That is, in the case of the example shown in the present embodiment, it is possible to collect useful information for specifying the cause of the sound heard by the user.

  In the present embodiment, an example has been described in which the trigger 1 is set such that the state information indicating the previous travel performed by the car 1 is included in the storage target period. In this example, it is possible to specify from which direction the car 1 has arrived at the departure floor. On the other hand, the period setting unit 25 may set the trigger 1 so that the state information indicating the previous run performed by the car 1 is not included in the storage target period. For example, the period setting unit 25 may set the trigger 1 so that only the state information indicating the current travel of the car 1 is included in the storage target period.

  In the present embodiment, an example in which sound information and state information are stored in storage unit 22 has been described. This is an example. Even when the user feels a vibration that the user does not normally feel while riding on the car 1, the user may feel that the vibration is caused by some abnormality. For this reason, the vibration information acquired by the vibration sensor 12 may be stored in the storage unit 22 as in the above example.

  In such a case, the storage unit 20 stores the vibration information acquired by the vibration sensor 12. The vibration information acquired by the vibration sensor 12 is stored in the storage unit 20 in association with the state information acquired at the same time. When the trigger 2 is set in S210, the storage unit 26 stores, in the storage unit 22, the state information and the vibration information acquired during the storage target period among the information stored in the storage unit 20 (S211). . In S211, the state information, the sound information, and the vibration information acquired during the storage target period may be stored in the storage unit 22.

  Hereinafter, other functions that can be adopted by the present elevator apparatus will be described. The elevator apparatus may employ a combination of a plurality of functions described below.

  For example, the status information stored in the storage unit 20 may include information indicating the temperature measured by the thermometer 9. In such a case, a range of the temperature of the hoisting machine 5 may be set as the traveling condition. In addition, the thermometer 9 may measure the temperature of the control device 7. In such a case, for example, a range of the temperature of the control device 7 is set as the traveling condition. The thermometer 9 may measure the temperature of the hoistway 3. In such a case, for example, a range of the temperature of the hoistway 3 is set as the traveling condition. When the thermometer 9 has a function of measuring humidity, the status information may include information indicating humidity. In such a case, a range of humidity is set as the traveling condition. For example, the generation of abnormal noise and vibration may be affected by the season or the air conditioning of the building. In this example, the storage unit 22 can store information indicating a driving state closer to the driving when the user hears the abnormal noise.

  As another example, the control device 7 may further include a detection unit 27. The detection unit 27 detects the number of times the car 1 has been started during a specific period based on the state information stored in the storage unit 20. The specific period is set in advance. The number of times the car 1 has been started is synonymous with the number of times the car 1 has traveled. In such a case, a range of the number of times the car 1 has been activated during the above-described specific period is set as the traveling condition. Only the upper limit may be set for the range of the number of times the car 1 has been started. The occurrence of abnormal noise and the occurrence of vibration may be affected by the number of times the car 1 is started. For example, when the number of starts of the car 1 is extremely small, the viscosity of the lubricating oil becomes large, and abnormal noise may be generated. In this example, the storage unit 22 can store information indicating a driving state closer to the driving when the user hears the abnormal noise.

  As another example, the control device 7 may further include a distribution calculation unit 28. The distribution calculation unit 28 calculates the distribution of the load of the car 1 from the video captured by the camera 13. Information indicating the distribution calculated by the distribution calculation unit 28 is stored in the storage unit 20 as part of the state information. In such a case, the range of the load distribution of the car 1 is set as the traveling condition. As the range of the load distribution of the car 1, for example, only the lower limit of the value indicating the load deviation may be set. The generation of abnormal noise and the generation of vibration may be affected by the distribution of the load of the car 1. For example, when the load of the car 1 is extremely biased, abnormal noise may occur. In this example, the storage unit 22 can store information indicating a driving state closer to the driving when the user hears the abnormal noise.

  As another example, the control device 7 may further include a distance calculation unit 29. The distance calculator 29 calculates the distance between the car 1 and the adjacent car. The adjacent car is a car that moves on the hoistway adjacent to the hoistway 3. Information indicating the distance calculated by the distance calculation unit 29 is stored in the storage unit 20 as a part of the state information. In such a case, a range of the distance between the car 1 and the adjacent car is set as the traveling condition. For the range of the distance between the car 1 and the adjacent car, only the lower limit value may be set. The generation of abnormal noise and the generation of vibration may be affected by the distance between the car 1 and the adjacent car. For example, abnormal noise may occur due to wind pressure when the car 1 passes by an adjacent car. In this example, the storage unit 22 can store information indicating a driving state closer to the driving when the user hears the abnormal noise.

  In the present embodiment, reference numerals 20 to 29 indicate functions of the control device 7. FIG. 8 is a diagram illustrating an example of hardware resources of the control device 7. The control device 7 includes a processing circuit 40 including, for example, a processor 41 and a memory 42 as hardware resources. The functions of the storage units 20 to 22 are realized by the memory 42. The memory 42 is, for example, a semiconductor memory. The memory 42 need not be a semiconductor memory. The control device 7 executes the programs stored in the memory 42 by the processor 41 to realize the functions of the respective units indicated by reference numerals 23 to 29.

  FIG. 9 is a diagram illustrating another example of the hardware resources of the control device 7. In the example illustrated in FIG. 9, the control device 7 includes a processing circuit 40 including, for example, a processor 41, a memory 42, and dedicated hardware 43. FIG. 9 illustrates an example in which some of the functions of the control device 7 are implemented by dedicated hardware 43. All the functions of the control device 7 may be realized by the dedicated hardware 43.
