Description

  Embodiments described herein relate generally to an elevator control device and an elevator control method.

  In recent years, as buildings rise in height, the shaking of buildings due to earthquakes and strong winds has become a problem. In particular, when the natural frequency of a building matches the natural frequency of a long object such as an elevator main rope or compen- sion rope installed in the hoistway in the building, the long object becomes in a resonance state, and the wall of the hoistway And there is a risk of contact with the installation in the hoistway.

  Therefore, using the fact that the natural frequency of a long object fluctuates depending on the position of the elevator car, the floor where the building and the long object do not resonate when a long-period vibration is caused by an earthquake or strong wind (non-resonant floor). ), The resonance between the building and the long object can be prevented.

JP 2012-126499 A

  On the other hand, the elevator is provided with an operation / pause switch for forcibly putting the elevator into a dormant state by an administrator's operation. When the operation / pause switch is operated at the time of a disaster or the like, the car is moved to a preset operation suspension floor such as the entrance floor, and the elevator is shifted to the suspension state on the floor. Thereby, passengers in the car can get off and evacuate on the operation suspension floor.

  However, the operation stoppage floor by operating this operation / pause switch is set for the convenience of evacuation in the event of a disaster, etc., regardless of whether the building and the long object resonate (resonance floor) or not. Therefore, the operation suspension floor may become a resonance floor.

  Therefore, if the building is shaken by an earthquake or strong wind when the operation / pause switch is operated and the car is stopped on the operation suspension floor, if the operation suspension floor is the resonance floor, the operation / pause is temporarily performed. The operation of the switch is disabled and the car is forcibly moved to the non-resonant floor. When the shaking is stopped, the operation of the operation / pause switch returns to an effective state, and the car is moved again to the operation suspension floor to shift to the operation suspension state, thereby preventing resonance.

  In other words, even if the operation / pause switch is operated, if a vibration occurs during the operation stop due to the operation, the car reciprocates between the operation stop floor and the non-resonance floor to prevent resonance. There was a problem of doing.

  The present invention has been made in view of the above circumstances, and it is possible to efficiently prevent the occurrence of resonance between a building and a long object of the elevator when a vibration occurs in the building during an operation stop of the elevator. An object is to provide an elevator control device and an elevator control method.

  According to the embodiment for achieving the above object, the elevator control device includes a resonance floor registration unit and an operation control unit. The resonance floor registration unit registers in advance as a resonance floor a stop floor of a car in which a long object in the elevator is in resonance with the building when the building vibrates. When the operation control unit acquires the operation stop signal for forcibly stopping the operation of the elevator, the operation control unit moves the car to a preset operation stop floor and opens the car door and the stop floor landing door for a predetermined time. After opening the door, close the door, and after closing the door, determine whether the operation suspension floor corresponds to the registered resonance floor, and if it is determined to do so, board the non-resonance floor that is a floor other than the resonance floor. After moving the car, put the elevator into a dormant state.

In addition, information on the hall call operations performed by the users at the halls 12-1 to 12-5 on the hall operation panels 121-1 to 121-5 is transmitted to the elevator control device 10 </ b> A and is sent to the hall call registration unit 103. It is registered.

  Then, based on the car call registered in the car call registration unit 102 and the landing call registered in the landing call registration unit 103, the operation control unit 105A controls the operations of the hoisting machine 4, the car door, the landing door, and the like. The elevator 1A is operating.

  Further, when the elevator 1A is in operation, the operation / pause switch 104 is fixed to the “operation” side. Further, the LED display unit 106 displays information indicating the current position of the car 6 and the driving / resting state based on the control state of the driving control unit 105A. An example of an external view of the elevator control device 10A in which these pieces of information are shown is shown in FIG.

  When an operation stop signal is output from the operation / pause switch 104, the operation control unit 105A responds to the car call registered in the car call registration unit 102 and the hall call registered in the hall call registration unit 103. Control is performed so as to move the car 6 to the first floor of operation suspension (S2).

  Next, when the car lands on the operation suspension floor (“YES” in S3), the car door and the landing door on the operation suspension floor “first floor” are opened for a predetermined time (S4). The user can get off from the car 6 and evacuate from the entrance of the building X by being opened on the operation stop floor “1st floor”.

  When the car door and the landing door are closed after a predetermined time has elapsed since the door was opened, it is determined whether or not the operation stop floor corresponds to the resonance floor registered in the resonance floor registration unit 101. (S5).

  Here, the operation suspension floor “1st floor” corresponds to the resonance floors (“1st floor” and “5th floor”) registered in the resonance floor registration unit 101 (“YES” in S5). The middle first floor (for example, “second floor”) is set as a new operation suspension floor, and the car 6 is controlled to move to the “second floor”. Then, when the car 6 reaches the non-resonant floor “second floor”, the elevator 1A is shifted to the operation suspension state (S6).

  When it is determined in step S5 that the operation stop floor does not correspond to the resonance floor (“NO” in S5), the elevator 1A is shifted to the operation stop state with the car 6 landing on the operation stop floor. (S7).

  According to the above first embodiment, when the elevator operation / pause switch is operated, the user is dismounted from the operation stop floor and then moved to the non-resonant floor to put the elevator in a stop state. Resonance between the building X and the elevator's long object without moving the car 6 to the non-resonant floor even when shaking occurs in the building during the suspension of operation Generation | occurrence | production can be prevented and safe and efficient control can be performed.

  In the first embodiment described above, the case where the operation stop signal is output as a result of the operation / stop switch being operated has been described. However, the elevator detects that a disaster has occurred in the building and automatically performs the control operation. Even when the operation stop signal is output by switching to the above, the operation of the elevator can be stopped by the same processing.
