The car 1 moves up and down in the hoistway 3. The balance weight 2 moves up and down on the hoistway 3. The car 1 and the balance weight 2 are suspended from the hoistway 3 by the main rope 4.

The main rope 4 is wound around the drive sheave 6 of the 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 the hoisting machine 5 and the control device 7 are installed in the machine room 8 above the hoistway 3. The hoisting machine 5 and the control device 7 may be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in the pit of the hoistway 3.

FIG. 1 shows an example in which the thermometer 9 is provided on the hoisting machine 5. The thermometer 9 measures the temperature of the hoisting machine 5. The temperature information 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 be provided with 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 in the car 1 to input information. For example, the operation panel 10 is provided with a destination button, an open button, and a close button. The 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 the intercom 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. The information of the 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. The doorway formed in the car 1 is opened and closed by the 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 at the landing 16 where the car 1 stops. The landing 16 is not provided with a device for driving the door 17. When the car 1 is stopped at the landing 16, the door 14 faces the door 17. The drive of the door 17 is performed by the electric motor 15 via the door 14.

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

The mobile terminal 19 is a terminal owned by an elevator maintenance staff. The mobile terminal 19 is connected to the control device 7 by wire or wirelessly. The mobile terminal 19 is, for example, a smart phone. 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 the function of the elevator device. The control device 7 includes, for example, a storage unit 20, a storage unit 21, a storage unit 22, a travel control unit 23, a determination unit 24, a period setting unit 25, and a storage unit 26.

The sound information acquired by the microphone 11 is stored in the storage unit 20. Information indicating the running state of the car 1 is stored in the storage unit 20. In the following, the information indicating the running state of the car 1 is also referred to as "state information". In the present embodiment, the "running of the car 1" includes an operation necessary for carrying the user in the car 1. Therefore, 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 associated with the state information acquired at the same time and stored in the storage unit 20.

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

The running conditions of the car 1 are stored in the storage unit 21. The traveling 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 running conditions are set in advance.

The functions of the elevator device will be described in detail below with reference to FIGS. 3 to 7. FIG. 3 is a flowchart showing an operation example of the control device 7.

The travel control unit 23 controls the travel of the car 1 (S101). For example, the travel 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 on which the landing 16 on which the landing button (not shown) is pressed is located. The travel 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 user's destination floor. The travel 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 associated with the state information and stored in the storage unit 20 (S102). As described above, the sound information and the state information may be always stored in the storage unit 20 regardless of whether or not the car 1 is running.

FIG. 4 is a flowchart showing another operation example of the control device 7. The operation flow shown in FIG. 4 is carried out in parallel with the operation flow shown in FIG. The control device 7 determines whether or not the traveling condition of the car 1 is set (S201). If the running conditions are stored in the storage unit 21, it is determined as Yes in S201. If the running 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 running 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. If the sound heard by the user is not loud enough to be judged as abnormal, no abnormality log will be left in the elevator device. In such a case, the maintenance worker who receives the report from the user inputs the condition from the mobile terminal 19 and stores the input condition in the storage unit 22 as the running condition of the car 1. An example of setting the running conditions of the car 1 from the mobile terminal 19 will be described below.

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 maintenance personnel 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 showing 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 sets the setting screen for setting the condition to the display 30 (S301). The condition setting unit 32 determines whether or not a condition has been input from the setting screen of the display 30 (S302).

The maintenance staff operates the input device 31 and inputs the conditions from the setting screen. For example, the maintenance staff inputs the departure floor of the car 1. The maintenance staff inputs the arrival floor of the car 1. The maintenance staff inputs the load range of the car 1. Only the lower limit value may be input as the load range of the car 1. For example, "60 kg or more" is input as the load range of the car 1. When the maintenance person presses the input completion button (not shown), S302 determines Yes. If it is determined to be 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 conditions input from the input device 31 are stored in the storage unit 21 as running conditions. In the following, 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 running conditions will be described.

When the determination is Yes in S201, the determination unit 24 determines whether or not the current traveling of the car 1 satisfies the traveling condition 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 on which the car 1 is currently located, matches the departure floor set as the traveling condition (S202). If it is determined to be Yes in S202, the determination unit 24 determines whether or not the load of the car 1 detected by the weighing device 18 is within the range of the load set as the traveling condition. If only the lower limit of the load is set as the running condition, the determination unit 24 determines whether or not the load of the car 1 detected by the weighing device 18 is larger than the lower limit (S203).

In the example shown in this embodiment, the running conditions include the initial conditions. The initial condition is a condition in which it can be determined that the current running of the car 1 is satisfied before the car 1 starts moving. The determinations of S202 and S203 are determinations relating to the initial conditions. That is, in S202 and S203, the determination unit 24 determines whether or not the running of the car 1 satisfies the initial condition before the car 1 starts moving. If the initial condition is satisfied, S203 determines Yes.

The period setting unit 25 sets in which period the information acquired is stored in the storage unit 22. In the following, the above period will be referred to as the storage 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 period setting unit 25 determines 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 so 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 or not the car 1 has started moving (S206). If it is determined Yes in S206, the determination unit 24 determines whether or not the car 1 has stopped (S207). When the determination is Yes in S207, the determination unit 24 determines whether or not the floor on which the car 1 is currently located 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).

If it is determined to be Yes in S208, the running condition is satisfied. When the period setting unit 25 determines Yes in S208, the period setting unit 25 sets the trigger 2 which is the end of 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 the state information and the sound information acquired during the storage target period among the information stored in the storage unit 20 in the storage unit 22 (S211). After that, 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 showing 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 the 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, among the information stored in the storage unit 20, the storage unit includes the state information representing the running state determined to satisfy the running condition and the sound information associated with the state information. It is stored in 22. Since the driving conditions are set according to the driving when the user hears an abnormal noise, there is a high possibility that the cause of the noise can be identified from the information stored in the storage unit 22. That is, in the example shown in the present embodiment, it is possible to collect useful information for identifying the cause of the sound generated by the user.

In the present embodiment, an example of setting the trigger 1 so that the state information indicating the previous run performed by the car 1 is included in the storage target period has been described. In this example, it is possible to specify from which direction the car 1 came to 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 running of the car 1 is included in the storage target period.

In the present embodiment, an example of storing sound information and state information in the storage unit 22 has been described. This is just an example. The user may feel that the vibration is caused by some abnormality even if he / she feels a vibration that he / she does not normally feel while riding in the car 1. Therefore, the vibration information acquired by the vibration sensor 12 may also be stored in the storage unit 22 in the same manner as in the above example.

In such a case, the vibration information acquired by the vibration sensor 12 is stored in the storage unit 20. The vibration information acquired by the vibration sensor 12 is associated with the state information acquired at the same time and stored in the storage unit 20. Then, when the trigger 2 is set in S210, the storage unit 26 stores the state information and the vibration information acquired in the storage target period among the information stored in the storage unit 20 in the storage unit 22 (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.

The other functions that can be adopted by this elevator device will be described below. The elevator device may be adopted by combining a plurality of functions shown below.

For example, the state information stored in the storage unit 20 may include information indicating the temperature measured by the thermometer 9. In such a case, the temperature range of the hoisting machine 5 may be set as the traveling condition. The thermometer 9 may measure the temperature of the control device 7. In such a case, for example, the temperature range of the control device 7 is set as the running condition. The thermometer 9 may measure the temperature of the hoistway 3. In such a case, for example, the temperature range of the hoistway 3 is set as the traveling condition. When the thermometer 9 has a function of measuring humidity, the state information may include information indicating humidity. In such a case, a humidity range is set as a running 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 running state closer to the running when the user hears an 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 is activated in 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 is activated 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 is activated during the specific period is set as the running condition. Only the upper limit value may be set in the range of the number of times the car 1 is activated. The generation of abnormal noise and the generation of vibration may be affected by the number of times the car 1 is started. For example, if the number of times the car 1 is started is extremely small, the viscosity of the lubricating oil may increase and abnormal noise may occur. In this example, the storage unit 22 can store information indicating a running state closer to the running when the user hears an abnormal noise.

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

As another example, the control device 7 may further include a distance calculation unit 29. The distance calculation unit 29 calculates the distance between the car 1 and the adjacent car. The adjacent car is a car that moves in the hoistway adjacent to the hoistway 3. The 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 distances between the car 1 and the adjacent car is set as a running condition. Only the lower limit may be set as the range of the distance between the car 1 and the adjacent car. The generation of abnormal noise and vibration may be affected by the distance between the car 1 and the adjacent car. For example, abnormal noise may be generated due to the wind pressure when the car 1 passes by the adjacent car. In this example, the storage unit 22 can store information indicating a running state closer to the running when the user hears an abnormal noise.

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 does not have to be a semiconductor memory. The control device 7 realizes the functions of the respective parts shown by reference numerals 23 to 29 by executing the program stored in the memory 42 by the processor 41.

FIG. 9 is a diagram showing another example of the hardware resource of the control device 7. In the example shown in FIG. 9, the control device 7 includes, for example, a processing circuit 40 including a processor 41, a memory 42, and dedicated hardware 43. FIG. 9 shows an example in which a part of the functions of the control device 7 is realized by the dedicated hardware 43. All the functions of the control device 7 may be realized by the dedicated hardware 43.
