一対 The second landing door 33 is provided with a pair of connecting rollers 45 as connecting members. The connection roller 45 includes a fixed side interlock roller and a movable side interlock roller.

The connecting roller 45 is sandwiched by the vane mechanism 19 when the car is landed and the first car door 2 is opened. As a result, the movable interlock roller rotates, and the locking device (not shown) is unlocked. Further, the vane mechanism 19 causes the second landing door 33 to interlock with the opening / closing operation of the first car door 2 by sandwiching the connecting roller 45.

The landing door girder 43 is provided with a landing door interlocking mechanism 46. The opening / closing operation of the second landing door 33 is transmitted to the first landing door 32 via the landing door interlocking mechanism 46.

FIG. 8 is a plan view showing a state in which a displacement has occurred between the first car door 2 and the second landing door 33 of FIG. 5 due to the earthquake. In the example of FIG. 8, interlayer displacement occurs in the building 50 due to the earthquake. As a result, the gap dimension changes to X + ΔX. Further, the second landing door 33 has an angle shift of the angle shift amount Δθ with respect to the first car door 2.

FIG. 9 is a plan view showing a state where the connecting roller 45 is sandwiched by the vane mechanism 19 of FIG. FIG. 10 is a plan view showing a state during the door opening operation of the vane mechanism 19 and the connecting roller 45 in FIG.

場合 Further, as shown in FIGS. 8 to 10, when the second landing door 33 is misaligned with respect to the first car door 2 due to the earthquake, a traveling loss occurs in the second landing door 33. Therefore, the angle shift amount can be estimated from the increase in the torque waveform as shown in FIG. The deformation of the landing door rail 44 due to the earthquake can also be estimated from the torque fluctuation.

FIG. 12 is a block diagram showing the door control device 22 of FIG. 3 and the health diagnostic device of the first embodiment. The door motor 15 is provided with a rotation detector 23 that generates a signal according to the rotation speed of the door motor 15. As the rotation detector 23, for example, a resolver or an encoder is used.

The door control device 22 has, as functional blocks, a speed command unit 22a, a speed control unit 22b, a current control unit 22c, a speed calculation unit 22d, and a filter processing unit 22e.

The speed command unit 22a generates a rotation speed command value of the door motor 15 for causing the first and

second car doors

2 and 3 to open and close, and outputs the rotation speed command value to the speed control unit 22b.

The speed control unit 22b corrects an error between the actual rotation speed of the door motor 15 and the rotation speed command value. The speed control unit 22b receives the rotation speed command value output from the speed command unit 22a and the actual rotation speed of the door motor 15 obtained from the speed calculation unit 22d and the filter processing unit 22e.

In FIG. 12, an error is obtained by inputting the rotation speed command value and the actual rotation speed of the door motor 15 to the first adder / subtractor 24. Then, the speed control unit 22b outputs the rotation speed command value with the error corrected to the current control unit 22c as a current command value.

The current control unit 22c controls the current supplied to the door motor 15 based on the current command value. The output of the current control unit 22c is input to the door motor 15 via a pulse width modulation inverter (not shown).

(4) The current control unit 22c corrects the current command value from the speed control unit 22b based on the current value detected by the current detector 25. In FIG. 12, an error is obtained by inputting the current command value from the speed control unit 22b and the current value detected by the current detector 25 to the second adder / subtractor 26.

The motor rotation position or the rotation speed can be estimated using the current value detected by the current detector 25 instead of the rotation detector 23.

The speed calculator 22d calculates the rotation speed by sampling the input rotation position at regular intervals, and outputs the rotation speed to the filter processor 22e.

The filter processing unit 22e performs low-pass filter processing on the input rotation speed. The low-pass filter process is a process of excluding a vibration component in a high frequency region and extracting a low frequency region necessary for speed control.

The door control device 22 has a computer. The function of the door control device 22 can be realized by arithmetic processing by a computer.

The soundness diagnostic device of the first embodiment has a diagnostic device main body 61. The diagnostic device main body 61 diagnoses the soundness of the diagnostic target after the occurrence of the earthquake. The diagnosis target is at least one of the building 50 and the elevator. In addition, the diagnostic device main body 61 determines, as the soundness of the diagnosis target after the occurrence of the earthquake, whether or not there is an abnormality that hinders the automatic restart of the elevator.

The diagnostic device main body 61 includes, as functional blocks, a speed detecting unit 61a, a torque detecting unit 61b, a gap estimating unit 61c, a storage unit 61d, a gap determining unit 61e as a diagnostic unit, a torque determining unit 61f as a diagnostic unit, and It has a reporting unit 61g.

The speed detector 61a detects the rotation speed of the door motor 15 based on the output from the rotation detector 23. The torque detector 61b detects the torque of the door motor 15 based on the current command value output from the speed controller 22b.

The gap estimating unit 61c estimates a gap size between the first vane 19a and the connection roller 45 when the door is completely closed, based on the rotation speed and the torque of the door motor 15. When estimating the gap size, the diagnostic device main body 61 outputs an estimation operation command to the door control device 22.

(4) Upon receiving the estimation operation command, the door control device 22 causes the first and

second car doors

2 and 3 to open at a lower speed than usual with the car 57 landing on the landing floor. At this time, the gap estimating unit 61c estimates the gap size from changes in the rotation speed and torque of the door motor 15.

The storage unit 61d stores a gap reference value corresponding to the gap size before the occurrence of the earthquake. The gap reference value is, for example, a gap size before the occurrence of an earthquake, or a value obtained by adding an allowable value to the gap size before the occurrence of an earthquake.

(4) The storage unit 61d stores a torque reference waveform corresponding to the torque waveform before the occurrence of the earthquake. The torque reference waveform is, for example, a torque waveform at the time of the door opening operation of the door motor 15 before the occurrence of the earthquake.

(4) The diagnostic device main body 61 periodically updates the gap reference value and the torque reference waveform. The update cycle is, for example, once a day, once a week, or once a month. The update may be performed when the elevator is started. The update may be performed when an update command is manually input.

The gap determining unit 61e determines whether there is an abnormality in the diagnosis target after the earthquake by comparing the post-earthquake estimated value, which is the estimated value of the gap size after the earthquake, with the gap reference value. Thereby, the gap determination unit 61e diagnoses the soundness of the diagnosis target after the occurrence of the earthquake.

When the gap size before the occurrence of the earthquake is used as the gap reference value, the gap determination unit 61e determines that there is an abnormality when the difference between the post-earthquake estimated value and the gap reference value exceeds an allowable value. When the value obtained by adding the allowable value to the gap dimension before the occurrence of the earthquake is used as the gap reference value, the gap determination unit 61e determines that there is an abnormality when the post-earthquake estimated value exceeds the gap reference value.

The torque determination unit 61f determines whether there is an abnormality in the diagnosis target after the earthquake by comparing the post-earthquake waveform, which is the torque waveform after the earthquake, with the torque reference waveform. Thereby, the torque determination unit 61f diagnoses the soundness of the diagnosis target after the occurrence of the earthquake.

The reporting unit 61g reports the determination results by the gap determining unit 61e and the torque determining unit 61f to the elevator control device 54 and a remote control room.

FIG. 13 is a flowchart showing the determination reference updating operation by the diagnostic device main body 61 of FIG. The diagnostic device main body 61 updates the gap reference value and the torque reference waveform at the above timing. When the criterion updating operation is started, the diagnostic device main body 61 outputs an estimation operation command to the door control device 22 in step S1.

Next, the diagnostic device main body 61 acquires information on the rotation speed and the torque of the door motor 15 in step S2. Then, in step S3, the diagnostic device main body 61 estimates the gap size based on the acquired information. Thereafter, in step S4, the diagnostic device main body 61 updates the gap reference value and the torque reference waveform, and ends the processing.

FIG. 14 is a flowchart showing a soundness diagnosis operation by the diagnosis device main body 61 of FIG. The diagnostic device main body 61 periodically executes the process of FIG. 14 at a set cycle. First, in step S11, the diagnostic device main body 61 confirms whether or not an earthquake of a set seismic intensity or higher has been detected.

If the earthquake has not been detected, the diagnostic device main body 61 ends the current process. If an earthquake has been detected, the diagnostic device main body 61 checks in step S12 whether the shaking of the earthquake has subsided. If the shaking has not stopped, the diagnostic device main body 61 ends the current process.

If the shaking has stopped, the diagnostic device main body 61 checks in step S13 whether the set time has elapsed. If the set time has not elapsed, the diagnostic device main body 61 ends the current process.

If the set time has elapsed, the diagnostic device main body 61 outputs an estimated operation command to the door control device 22 in step S14. Subsequently, the diagnostic device main body 61 acquires information on the rotation speed and the torque of the door motor 15 in step S15. Then, in step S16, the diagnostic device main body 61 estimates the gap size after the occurrence of the earthquake based on the acquired information.

After that, in step S17, the diagnostic device main body 61 determines whether there is any abnormality in the diagnosis target. Subsequently, in step S18, the diagnostic device main body 61 outputs the determination result to the elevator control device 54 and the remote control room, and ends the processing.

As described above, in the health diagnostic device of the first embodiment, the diagnostic device main body 61 estimates the gap size from the rotation speed and the torque of the door motor 15. Then, the diagnostic device main body 61 diagnoses the soundness of the diagnosis target after the occurrence of the earthquake by comparing the gap size after the occurrence of the earthquake with the gap reference value. Therefore, the configuration can be simplified and the cost can be reduced.

(4) The diagnostic device main body 61 diagnoses the soundness of the diagnosis target after the occurrence of the earthquake by comparing the torque waveform of the door motor 15 with the torque reference waveform. Therefore, the configuration can be simplified and the cost can be reduced.

診断 Moreover, the diagnostic apparatus main body 61 can estimate the degree of the interlayer displacement due to the earthquake from the gap size and the torque fluctuation, and can diagnose the soundness of the diagnosis target.

(4) The diagnostic device main body 61 periodically updates the gap reference value and the torque reference waveform. For this reason, the secular change can be removed and the damage caused by the earthquake can be estimated more accurately.

It is preferable that the gap reference value and the torque reference waveform are set for each landing floor. In addition, although the soundness diagnosis operation is preferably performed on all landing floors, a part of the landing floors may be selected and executed.

閾値 Alternatively, the threshold value of the gap dimension may be manually set as the gap reference value. Similarly, the torque reference waveform may be manually set.

The gap size may be estimated from only the rotation speed or the torque of the door motor 15.

Further, in the first embodiment, the single-door type door device is described, but the door device may be a centrally-open type. Further, the number of doors is not limited to two.

連結 In addition, the connecting member is not limited to the connecting roller 45.

Embodiment 2 FIG.
Next, FIG. 15 is a configuration diagram showing a health diagnostic apparatus according to Embodiment 2 of the present invention. The soundness diagnostic device of the second embodiment has a gap detector 71 and a diagnostic device main body 62. The gap detector 71 is provided in the car 57. The gap detector 71 is installed on the ceiling of the cab.

隙間 The gap detector 71 detects a gap dimension between the car sill 72 and the landing sill 73. As the gap detector 71, for example, a camera is used. The car sill 72 is installed on the floor of the car entrance 1. The landing sill 73 is installed on the floor of the landing entrance 31.

The diagnostic device main body 62 according to the second embodiment diagnoses the soundness of the diagnosis target after the occurrence of the earthquake by comparing the gap size after the occurrence of the earthquake with the gap reference value. Further, the diagnostic device main body 62 has a gap detection unit 62a, a storage unit 62b, a gap determination unit 62c, and a notification unit 62d as functional blocks.

The gap detection unit 62a obtains a gap dimension between the car threshold 72 and the landing threshold 73 based on a signal from the gap detector 71. The storage unit 62b stores a gap reference value that is a value corresponding to the gap dimension before the occurrence of the earthquake.

The gap reference value is, for example, a gap dimension before the occurrence of an earthquake or a value obtained by adding an allowable value to a gap dimension before an earthquake. The diagnostic device main body 62 periodically updates the gap reference value, similarly to the gap reference value of the first embodiment.

The gap determining unit 62c compares the post-earthquake dimension, which is the gap dimension after the occurrence of the earthquake, with the gap reference value to determine whether there is an abnormality in the diagnosis target after the occurrence of the earthquake.

(4) When the gap size before the occurrence of the earthquake is used as the gap reference value, the gap determination unit 62c determines that there is an abnormality when the difference between the post-earthquake dimension and the gap reference value exceeds an allowable value. When a value obtained by adding an allowable value to the gap size before the occurrence of the earthquake is used as the gap reference value, the gap determination unit 62c determines that there is an abnormality when the size after the earthquake exceeds the gap reference value.

The diagnostic device main body 64 obtains the gap size when the car 57 is stopped at the first position by the same estimation method as in the first embodiment. Further, the diagnostic apparatus main body 64 obtains the gap size when the car 57 is stopped at the second position vertically displaced from the first position by the same estimation method as in the first embodiment.

診断 The diagnostic device main body 64 also determines the difference between the gap size at the first position and the gap size at the second position. The first position and the second position are positions where the connecting roller 45 is disposed inside the vane mechanism 19 on the same landing floor.

The storage unit 64d stores the estimated gap size. In addition, the storage unit 64d stores an allowable angle of inclination of the car 57.
