JP4973014B2 - Seismic control system for elevators - Google Patents

Description

  This invention is generated due to resonance of ground motion, building structure, and ground motion, among other earthquake control operations for quickly removing passengers in an elevator installed in a building from a car when an earthquake occurs. Seismic control operation of an elevator to ensure the safety of passengers in the elevator installed in the building and to minimize equipment damage when a long-period earthquake with a long period of ground motion occurs in the building It is about the system.

  The conventional elevator seismic control operation system is equipped with a P-wave seismic detector that detects initial tremors or an S-wave seismic detector that detects main oscillation, and when the seismic sensor operates, the elevator is moved to the nearest floor. Control operation is performed such as stopping or stopping suddenly when an earthquake with a large seismic intensity is detected by the S-wave earthquake detector.

  In such a seismic control operation system, the seismic detector operation information is transferred from the building to the management base, and the control instruction is transmitted from the management base to cause the elevator to perform seismic control operation. There is also known a system capable of reliably executing a device for reducing the number of devices and a seismic control operation (see, for example, Patent Document 1).

  In addition, during seismic control operation, the seismic detectors installed in the building are not operated, but the seismic detectors installed at various points in the country are distributed via the Internet, and earthquake information is obtained in advance. There is also known an elevator seismic control operation system that obtains passengers from a car at an evacuation floor or the nearest floor before an earthquake wave arrives (see, for example, Patent Documents 2 and 3).

  There is also known a system that detects strong winds with a wave energy detector and performs a stop operation to the nearest floor and a movement to an intermediate floor (see, for example, Patent Document 4).

  The conventional elevator seismic control operation system detects the acceleration or speed of seismic motion, and performs seismic control operation according to the magnitude, so it considers earthquakes with large acceleration as dangerous and performs a sudden stop, etc. The system was designed to continue normal operation or to stop to the nearest floor, assuming that earthquakes with low acceleration are low risk.

  In addition, the seismic control operation system using the Internet distribution of earthquake information also obtains the magnitude of earthquake motion from the magnitude information included in the earthquake information, and seismic control operation such as the nearest floor stop based on the magnitude of the earthquake magnitude It was something to do.

  As mentioned above, in the conventional seismic control operation system, the earthquake risk is set based on the magnitude of the seismic wave and the magnitude of the acceleration, so the seismic wave acceleration is small and detection by the seismic detector is impossible. However, the seismic wave is amplified by the ground structure and the building structure, and it cannot always cope with the long-period earthquake that causes damage to the building and the equipment in the elevator hoistway due to the resonance of the building.

  The present invention has been made to solve the above-described problems. When a long-period earthquake having a long period of ground motion occurs in a building, the safety of passengers in an elevator installed in the building is ensured. An elevator seismic control operation system that minimizes equipment damage is provided.

The elevator seismic control operation system according to the present invention includes a long-period earthquake detection device that detects a long-period earthquake when a long-period earthquake occurs, and the long-period earthquake detection device detects a long-period earthquake. Next, move the elevator to the nearest floor stop operation, perform the first control operation to safely remove the passenger from the elevator car, and then move the elevator car to the dormant floor that is not affected by long-period earthquake vibration In the elevator seismic control operation system that performs the second control operation, the first control operation moves from the nearest floor stop operation to the nearest floor stop state, and the car door opening button is pressed. Recognize that there are passengers in the car and continue the nearest floor stop state. If the car door open button is not pressed, the long-period earthquake detection time by the long-period earthquake detection device Determining whether the upper course, continue to the nearest floor stop state if it has elapsed, the second control operation operation, when the long-period earthquake detection time is less than resting floor operation proceeds threshold, It shifts to a stop floor stop operation and maintains a stop floor stop state .

  The long-period earthquake detection device generates long-period earthquakes using data simulated on the basis of earthquake information distributed via the Internet, the structure of the building where the elevator is installed, and the ground structure near the building. Is predicted and detected.

  According to the present invention, it is possible to detect a long-period earthquake that cannot be detected by a control operation using a conventional earthquake detector and to evacuate passengers safely. In addition, due to the resonance of the building caused by a long-period earthquake, the main rope that suspends the elevator car and counterweight resonates, and it is possible to reduce damage to equipment caused by collision with equipment in the hoistway. Become.
