The abnormality detection device 9 compares the measured drive pulley rotation speed Ml and the reference drive pulley rotation speed Rl, and detects an abnormality of the drive motor 101.

[0056] Specifically, in a case where the measured drive pulley rotation speed Ml and the reference drive pulley rotation speed Rl coincide with each other, the abnormality detection device 9 determines that the drive motor 101 has no abnormality. On the other hand, in a case where the measured drive pulley rotation speed Ml and the reference drive pulley rotation speed Rl do not coincide with each other, the abnormality detection device 9 determines that the drive motor 101 has an abnormality.

[0057] Whether the measured drive pulley rotation speed Ml and the reference drive pulley rotation speed Rl coincide with each other is determined based on whether a difference between the measured drive pulley rotation speed Ml and the reference drive pulley rotation speed Rl is within a range set in advance.

[0058] Further, the abnormality detection device 9 detects an abnormality of the drive pulley 104, the drive belt 105, and the driven pulley 106 using the measurement result of the first rotation speed measuring device 5 and the measurement result of the second rotation speed measuring device 6.

[0060] Specifically, in a case where the measured driven pulley rotation speed M2 and the predicted driven pulley rotation speed R2 coincide with each other, the abnormality detection device 9 determines that the drive pulley 104, the drive belt 105, and the driven pulley 106 have no abnormality. On the other hand, in a case where the predicted driven pulley rotation speed R2 and the measured driven pulley rotation speed M2 do not coincide with each other, the abnormality detection device 9 determines that any of the drive pulley 104, the drive belt 105, and the driven pulley 106 has an abnormality.

[0061] Whether the predicted driven pulley rotation speed R2 and the measured driven pulley rotation speed M2 coincide with each other is determined based on whether a difference between the predicted driven pulley rotation speed R2 and the measured driven pulley rotation speed M2 is within a range set in advance.

[0065] Specifically, in a case where the measured drive roller rotation speed M3 and the measured driven roller rotation speed M4 coincide with each other, the abnormality detection device 9 determines that the drive roller 107, the link rope 108, and the driven roller 109 have no abnormality. On the other hand, in a case where the measured drive roller rotation speed M3 and the measured driven roller rotation speed M4 do not coincide with each other, it is determined that the drive roller 107, the link rope 108, and the driven roller 109 have an abnormality.

[0066] Whether the measured drive roller rotation speed M3 and the measured driven roller rotation speed M4 coincide with each other is determined in accordance with whether the difference between the measured drive roller rotation speed M3 and the measured driven roller rotation speed M4 is within a range set in advance.

Specifically, the abnormality detection device 9 detects the abnormality of each of the first hoist roller 117, the second hoist roller 118, the third hoist roller 119, and the fourth hoist roller 120 as follows.

[0069] The abnormality detection device 9 predicts the rotational speed of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120, based on the measured driven roller rotational speed M4. In the elevator door device system of Embodiment 1, the predicted rotational speed of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120 is the same as the others. Therefore, the predicted rotational speed of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120 is set as the predicted hanger roller rotational speed R3.

[0070] In addition, the abnormality detection device 9 can detect the abnormality of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120, using the measurement result of the second rotational speed measuring device 6 and the measurement result of the fourth rotational speed measuring device 8. In this case, the abnormality detection device 9 predicts the rotational speed of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120, based on the measured driving roller rotational speed M3.

[0071] The abnormality detection device 9 compares the measured first hanger roller rotational speed M5 and the predicted hanger roller rotational speed R3, and detects the abnormality of the first hanger roller 117.

[0073] The movement path of each of the first, second, third, and fourth hanger rollers 117, 118, 119, and 120 is constituted by an acceleration process, a constant speed process, and a deceleration process.

[0074] The abnormality detection device 9 calculates the amount of change in the rotational speed of the first hanger roller 117 per unit time in the acceleration process of the first hanger roller 117, based on the measured first hanger roller rotational speed M5. The calculated amount of change in the rotational speed of the first hanger roller 117 per unit time is set as the acceleration process first hanger roller rotational speed change amount R4. The abnormality detection device 9 detects the abnormality of the door rail 110 on which the first hanger roller 117 rolls in the acceleration process of the first hanger roller 117, using the acceleration process first hanger roller rotational speed change amount R4.

[0075] Specifically, in a case where the acceleration process first hanger roller rotational speed change amount R4 is not disturbed, the abnormality detection device 9 determines that the door track 110 rolled by the first hanger roller 117 during the acceleration process of the first hanger roller 117 is not abnormal.

[0076] According to whether or not the acceleration process first hanger roller rotational speed change amount R4 is within a range set in advance, it is determined whether or not the acceleration process first hanger roller rotational speed change amount R4 is disturbed.

[0077] Further, the abnormality detection device 9 detects an abnormality of the door track 110 rolled by the first hanger roller 117 during the constant speed process of the first hanger roller 117 using the measured first hanger roller rotational speed M5.

[0078] Specifically, in a case where the measured first hanger roller rotational speed M5 is not disturbed, the abnormality detection device 9 determines that the door track 110 rolled by the first hanger roller 117 during the constant speed process of the first hanger roller 117 is not abnormal. On the other hand, in a case where the measured first hanger roller rotational speed M5 is disturbed, the abnormality detection device 9 determines that the door track 110 rolled by the first hanger roller 117 during the constant speed process of the first hanger roller 117 is abnormal.

[0079] According to whether or not the measured first hanger roller rotational speed M5 is within a range set in advance, it is determined whether or not the measured first hanger roller rotational speed M5 is disturbed.

[0080] Further, the abnormality detection device 9 calculates, based on the measured first hanger roller rotational speed M5, a change amount of the rotational speed of the first hanger roller 117 per unit time during the deceleration process of the first hanger roller 117. The calculated change amount of the rotational speed of the first hanger roller 117 per unit time is set as a deceleration process first hanger roller rotational speed change amount R5.
