Problems solved by technology

However, in the conventional technology, since it is judged only at this point of time whether the amplitude of the long object exceeds the above-mentioned threshold value, there is a problem that it is difficult to properly perform the normal operation of the elevator.

[0040] figure 1 It is the structural diagram of an ordinary elevator. The elevator system of this embodiment is configured such that the elevator car 1 and the counterweight 2 move up and down along a guide rail not shown. The elevator car 1 and the counterweight 2 are suspended in the shape of a bucket by the main rope 7 wound on the hoist 4 in the machine room 12 located on the upper part of the hoistway 11, and are driven by the main rope 7. In addition, a control panel 3 , a governor 6 , and a vibrating meter 5 are installed in the machine room 12 , and a governor rope 8 is wound around the governor 6 . In addition, a compensating rope 9 for compensating for a weight difference between the main rope 7 on the side of the elevator car 1 and the side of the counterweight 2 is provided when viewed from the hoist side. Furthermore, a pigtail cable 10 for supplying power to the elevator car 1 is provided. As described above, elongated objects such as the main rope 7 , the gov...

[0051] In the above-mentioned first embodiment, when the swaying of a long object exceeding a predetermined threshold occurs or is predicted to occur, the controller 100 controls the elevator so that the elevator does not stop at all resonance floors. However, when most of the floors are resonant floors, it may not always be possible to improve passenger convenience because there are too many non-stop floors. In order to solve this problem, the elevator is controlled so that the elevator passes through the resonant floors in stages, and the method will be described below. It should be noted that since the structure of the elevator equipment is the same as that of the first embodiment, its description is omitted here. The control method of the regulated operation in this embodiment will be described below with reference to the flow chart.

[0052] Such as Figure 4 As shown, the controller 100 is the same as the case of the first embodiment. After performing the respective pr...

[0058]In the above-mentioned second embodiment, the controller 100 performs staged regulation and operation control on the elevator, but in addition, for example, the following situation also exists: when the maximum shaking amount of a long-sized object reaches the threshold value of level 2 or is predicted In the case of reaching the threshold of level 2, if the threshold is exceeded too much, the long-sized object will be damaged. Therefore, in order to cope with this situation, a reference threshold (level 3) indicating how much the shaking amount exceeds the maximum threshold or is predicted to be exceeded is further set. When the shaking amount of a long-sized object reaches the threshold or is predicted to be When this threshold is reached, the controller 100 forcibly stops the elevator. The above case will be described below. Since the structure of the elevator apparatus is the same as that of the first embodiment and the second embodiment, its description is omitted ...

Abstract

The invention provides an emergency operation device for an elevator, and a method thereof. The emergency operation device for the elevator controls the elevator to perform emergency operation if vibration of a building is detected. The emergency operation device comprises: a vibrometer for detecting the vibration of the building; a shaking amount calculating unit for calculating in real-time, for each floor of the building, the natural period of the building and the shaking amount of an elongated object in an elevator hoistway in a period near the natural period based on a detection signal upon the detection of vibration by the vibrometer; and an operation control unit which, if the shaking amount of any period of each floor calculated by the shaking amount calculating unit reaches a specified threshold stored in a storage unit, determines the floor with the shaking amount to be a resonance floor, or if the shaking amount is predicted to reach a threshold, determines the floor that is predicted to have the shaking amount to be a possible resonance floor, and controls the elevator to perform emergency operation such that the elevator does not stop at the resonance floors and the possible resonance floors.

Description

technical field [0001] The present invention relates to a controlled operation device of an elevator and a method thereof. The controlled operation device of an elevator detects the vibration of a building during an earthquake or a strong wind, and issues a controlled operation command to an elevator installed in the building. Background technique [0002] When a long-term earthquake or strong wind occurs, although the shaking acceleration of the building is not large, due to the shaking of the upper part of the building, the main rope of the elevator, the rope of the governor, the cable used to supply power to the elevator car or The tail cables of the cables used for signal communication (hereinafter, the above-mentioned components are collectively referred to as "long-sized objects") are prone to shaking, and when the long-sized objects shake in the hoistway, they will collide with the elevator equipment and cause damage. [0003] In order to improve the above problems, v...
