- the value of the response magnification changes according to the characteristics of the building such as the structure of the building, the height of the building, the structure of the floors of the building, and the like. In general, in a relatively low building, the value of the response magnification increases with the height of the floor.

Specifically, for example, the operation control unit 26 determines whether or not the call registration of the car 11 is performed when normal operation is being performed. When determining that the call registration of the car 11 has not been performed, the operation control unit 26 determines whether or not the inside of the car 11 is unmanned.

- FIG. 5 is a diagram showing a first example of property damage evaluation value information stored in the elevator control device according to the first embodiment.
- FIG. 6 is a diagram showing a second example of property damage evaluation value information stored in the elevator control device according to the first embodiment.
- FIG. 5 shows a first example of property damage evaluation value information stored in the storage unit 23 .
- the storage unit 23 stores information indicating unweighted property damage evaluation values. If an object is likely to be damaged during an earthquake, the property damage evaluation value corresponding to the object is defined as "1". If there is no possibility that an object will be damaged during an earthquake, the property damage evaluation value corresponding to the object is determined as "0".
- property damage evaluation values are set for the relative displacement device that is the first object and the long object that is the second object inside the hoistway 3 .
- the relative displacement devices As the relative displacement devices, a "floor landing device” that is a set of the landing position detection device 14 and the detection target 16, a set of the threshold of the car door 12 and the threshold of the landing door 6, and the engagement roller 7 and the engagement vane 13 "Door sill/engagement device", etc. are considered.
- the physical damage evaluation value of the relative displacement device which is the first object, is an evaluation value that indicates the relationship between the position where the car 11 exists and the possibility of damage to the relative displacement device during an earthquake.
- the property damage evaluation value of the long object which is the second object, is an evaluation value that indicates the relationship between the position where the car 11 exists and the possibility of damage due to resonance of the long object during an earthquake.
- the value of "car height” is the value of the position of the car 11 in the vertical direction.
- the value of "cage height” is considered to be a range from 0m to 15m, which is the vertical range in which the car 11 can move.
- the "Cage Height” value is considered in 1m intervals.
- the position where the "car height” is 3 m is the landing position of a certain landing 5. If an earthquake occurs while the car 11 is at a height of 3 m, there is a possibility that the "landing device” and the “door sill/engagement device”, which are relative displacement devices, will interfere with each other and be damaged. Further, in this case, since the main rope 9 on the car 11 side is relatively long, the amplitude of string vibration due to resonance is large. Therefore, the main rope 9 on the car 11 side may be damaged by resonance.
- the amplitude of the string vibration is the largest at the central portion of the governor rope 21 .
- the car 11 and the governor rope 21 may interfere with each other and the governor rope 21 may be damaged.
- Total value of damage evaluation values is the total value of damage evaluation values determined for each position of the car 11 in the vertical direction. For example, the operation control unit 26 identifies the position of the car 11 with the smallest total damage evaluation value. If there are a plurality of positions of the car 11 at which the sum of damage evaluation values is the smallest, the operation control unit 26 identifies one of the positions of the car 11 at which the sum of the damage evaluation values is the smallest. For example, as shown in FIG.
- the positions of the car 11 where the total value of the damage evaluation values is the smallest are the "car heights" of 1 m, 2 m, 4 m, 5 m, 6 m, 7 m, 9 m, 10 m, 11 m, The positions are 12m and 14m. Note that the operation control unit 26 may calculate the total value of the damage evaluation values each time the retracted position is determined.
- FIG. 6 shows a second example of the property damage evaluation value information stored in the storage unit 23 .
- the storage unit 23 stores information indicating weighted property damage evaluation values.
- the calculation unit 25 performs a weighting calculation that indicates the property damage evaluation value stored in the storage unit 23, and updates the information on the property damage evaluation value stored in the storage unit 23 based on the calculation result.
- the weighting calculation may be performed by an external device other than the control device 17, and the information of the physical damage evaluation value stored in the storage unit 23 may be updated by the external device.
- the property damage evaluation value for the relative displacement equipment is weighted based on the building response magnification.
- the magnitude of horizontal shaking on each floor of the building 2 increases with the height of the floor. That is, the value of the building response magnification increases as the floor of the building 2 increases. Therefore, when weighting is performed based on the building response magnification, the property damage evaluation value for the relative displacement device increases as the value of the car height increases.
- the property damage evaluation value for long objects is weighted based on the maximum resonance magnification, which is the maximum resonance magnification.
- the lower the height position of the car 11 the longer the length of the car-side portion of the main rope 9.
- the length of the elongated object that is less likely to cause resonance of the elongated object can be calculated.
- the resonance magnification value of the main rope 9 on the car side is set to 0 when the height position of the car 11 is 5 m or more.
- the total property damage evaluation value is the sum of weighted property damage evaluation values for multiple objects. For example, even if there is a possibility of damage to an object for all car heights, the optimum retraction position can be determined based on the total property damage evaluation value. Specifically, the position in the vertical direction of the car 11 at which the total value of the property damage evaluation values is the smallest is determined as the retracted position. For example, in FIG. 6, when the car 11 exists at positions where the car heights are 4 m, 6 m, 9 m, and 11 m, the total property damage evaluation value is the smallest. In this case, one of these positions is determined as the retracted position.
- calculation unit 25 may weight the physical damage evaluation value of one or more objects instead of weighting all the objects provided in the elevator system 1 . Further, the calculation unit 25 may perform a weighting calculation so that the physical damage evaluation value for the object of importance is increased.
- FIG. 7 is a flow chart for explaining the outline of the operation of the elevator control device according to the first embodiment.

前記演算部は、前記外部情報取得部が外部から地震の主要動の情報を取得した後に、前記外部情報取得部が取得した地震の主要動の情報に基づいて、前記記憶部が記憶する前記物損評価値情報に含まれる前記第1物体の物損評価値および前記第2物体の物損評価値のうち少なくとも一方に対して重み付けを行った物損評価値を演算し、演算した結果に基づいて前記記憶部が記憶する前記物損評価値情報を更新する請求項3に記載のエレベーターの制御装置。 - 前記記憶部は、前記エレベーターが設置された建築物の複数の階床の各々について前記かごの停止頻度の情報を記憶し、
前記運転制御部は、前記退避位置を決定するときに、前記記憶部が記憶する前記かごの停止頻度の情報に基づいて前記かごが停止する頻度の高い階床の周辺位置を優先的に前記退避位置として決定する請求項1から請求項7のいずれか一項に記載のエレベーターの制御装置。 - 前記記憶部は、前記エレベーターが利用される頻度を時間帯ごとに示す利用頻度の情報を記憶し、
前記運転制御部は、前記記憶部が記憶する前記利用頻度の情報に基づいて、前記エレベーターが利用される頻度が高い時間帯には前記かごを前記退避位置へ移動させず、前記エレベーターが利用される頻度が低い時間帯に前記かごを前記退避位置へ移動させる請求項1から請求項7のいずれか一項に記載のエレベーターの制御装置。 - 前記エレベーターが設置された建築物に地震による初期微動が到達したことを感知した場合、地震による主要動が前記建築物に到達することが推定される時刻までに前記かごの到達可能な階床の範囲を演算する範囲演算部、
を備え、
前記運転制御部は、前記範囲演算部が演算した前記かごの到達可能な階床の範囲に含まれる位置を前記退避位置として決定する請求項1から請求項9のいずれか一項に記載のエレベーターの制御装置。 - 前記範囲演算部は、前記建築物に地震による初期微動が到達した後に前記かごが最寄りの階で停車した場合、地震による主要動が前記建築物に到達することが推定される時刻までに前記かごの到達可能な階床の範囲を演算し、
前記運転制御部は、地震による初期微動が到達した場合に前記かごを最寄り階に停車させ、その後に前記範囲演算部が前記かごの到達可能な階床の範囲を演算した場合に、前記かごの到達可能な階床の範囲に含まれる位置を前記退避位置として決定する請求項10に記載のエレベーターの制御装置。
