Problems solved by technology

[0012] As mentioned above, the conventional earthquake control operation system sets the risk of an earthquake based on the size of the seismic wave and the magnitude of the acceleration. A long-period earthquake in which seismic waves are amplified due to the foundation structure or building structure and the building resonates, causing damage to the building and the equipment in the elevator passageway

Embodiment approach 1

[0029] Fig. 1 is a schematic diagram showing an ascending and descending path of an elevator earthquake control operation system in Embodiment 1 of the present invention. The elevator car 101 is suspended by main ropes 102 and moves up and down by the rotation of a hoist 103 . In addition, the load on the hoist 103 is reduced by balancing the elevator car 101 with the counterweight 104 .

[0030] Numerals 105-1 to 105-7 show the halls of each floor, and each show halls from the first floor to the seventh floor. For example, when the elevator car 101 passes the second floor 105-2 in the ascending direction, the nearest stop floor of the elevator car 101 is the fourth floor 105-4. In Fig. 1, the closest docked layer is indicated by a bold line. In addition, for example, let the base station of the building be the first floor 105-1. In FIG. 1, base stations are indicated by double lines.

Embodiment approach 2

[0047] In Embodiment 1 above, although it is judged in step S606 whether the long-period earthquake detection time exceeds the base station stop operation transition threshold value, it is also possible to immediately transfer to the base station without performing the judgment process of the long-period earthquake detection time in step S606. Stop operation, so as to reduce the damage of the machine in the lifting passage more quickly.

Embodiment approach 3

[0049] In the first embodiment described above, long-period earthquakes are detected through the operation of the long-period earthquake detection device 201 in step S602, but the detection of long-period earthquakes in step S602 may not be performed by the long-period earthquake detection device 201. Earthquake information transmitted through the Internet, and data simulated based on information such as building structures and foundation structures near the buildings, etc., new detection devices that predict the occurrence of long-period earthquakes are shifting to the above-mentioned earthquake control operation.

Abstract

The invention provides an earthquake control running system of elevator. When longperiod earthquake happens to building, the safety of passenger in the elevator of the building can be assured and the damage of the machine can be reduced to minimum limit. When a longperiod earthquake detection device (201) detects longperiod earthquake, the control running of elevator is performed. And, when the longperiod earthquake detection device detects longperiod earthquake, the first control running of elevator is performed to make the elevator move to the nearest floor to stop and then the passenger can go out from elevator car safely; and then the second control running of elevator is performed to male the elevator car move to preset position which not effected by shocking of longperiod earthquake.

Description

technical field [0001] The present invention relates to an earthquake control operation system of an elevator. When an earthquake occurs, even in the earthquake control operation used to release passengers in an elevator installed in a certain building from the car as soon as possible, especially when the ground or building When a long-period earthquake with a long earthquake period occurs in the building due to the resonance between the structure of the building and the earthquake, it can also ensure the safety of passengers in the elevator installed in the building and reduce the damage to the machine to a minimum. minimum. Background technique [0002] In the conventional earthquake control operation system of elevators, a P-wave seismic detector for detecting initial micromotions or an S-wave seismic detector for detecting main vibrations is installed, and the control operation is performed as follows: When the above-mentioned earthquake detectors operate, the elevator s...
