Description

  This invention ensures the safety of passengers in the event of an earthquake, especially in the event of an earthquake control operation to quickly remove passengers in an elevator installed in a building from the car before the earthquake reaches the elevator. The present invention relates to an elevator seismic control operation system for minimizing equipment damage.

  Conventional elevator seismic control operation systems are equipped with a P-wave seismic detector that detects the occurrence of initial tremors, or an S-wave seismic detector that detects major motions, 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 an earthquake operation control system, the earthquake detector operation information is transferred from the building to the management base, and the control instruction is distributed from the management base to cause the elevator to perform the 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, seismic waves are analyzed by seismometers installed at various locations throughout the country, not after the seismic detectors installed in the building are operating, and the obtained information is distributed via the Internet. In addition, there is also known an elevator earthquake control operation system in which passengers are taken down from a car at an evacuation floor or the nearest floor before earthquake waves arrive by acquiring earthquake information in advance (for example, Patent Documents 2 and 3). reference).

  In the conventional elevator seismic control operation system, since seismic control operation is performed after the operation of the seismic detector, even if a seismic motion occurs, equipment in the hoistway collides or the rope vibrates violently The elevator had to be moved, which often caused damage to the rails and equipment in the hoistway.

  In addition, in the seismic control operation system by the Internet distribution of earthquake information, which is one means for solving the problem of the system, when the earthquake information is received, the predicted arrival time of the earthquake wave included in the earthquake information Based on this, the control operation of the elevator is controlled.

  This invention was made in order to solve the above-mentioned problems. For elevator control operation based on earthquake information, the elevator control means is changed according to the presence or absence of passengers in the car, ensuring passenger safety. It is an object of the present invention to provide an elevator seismic control operation system that can reliably and appropriately prevent damage to elevator equipment.

In the elevator operation control system according to the present invention, the earthquake information receiving device for receiving an earthquake early warning including information such as the earthquake source, magnitude, and depth, and the information included in the received emergency earthquake early warning, It is installed in the earthquake information prediction means that predicts at least the time when the main motion of the earthquake will arrive at any point, the elevator car that transports the elevator passengers, and the elevator overnight, and measures the weight of the elevator car Equipped with a weighing device that detects presence / absence and an elevator control means that inputs information from the weighing device and controls the elevator car. When an earthquake early warning is received, the elevator control is based on passenger presence / absence information from the weighing device. in those carrying out the running operation, control operation the operation of the elevator the elevator control means to practice receives the earthquake early warning, emergency areas If the main movement arrival time, which is the time required for the main movement to arrive, is sufficiently long, as determined from the preliminary report, the elevator will immediately move to a position where there is little impact from the earthquake when it is detected by the weighing device that there are no passengers. When the presence of a passenger is detected by the scale device, the nearest floor is immediately stopped .

  In addition, the elevator control operation performed by the elevator control means is to receive the emergency earthquake early warning, and the main motion arrival time, which is the time required for the main motion to arrive, is calculated from the emergency earthquake early warning. When the time is smaller than the time to be performed, the balance device suddenly stops when it is detected that there is no passenger in the elevator car, and when the passenger is detected by the scale device that there is no passenger in the elevator car, a slow stop is performed.

  According to the present invention, even when the control operation of the elevator at the time of earthquake can be started only after the occurrence of the conventional earthquake, the elevator can be shifted to the stop operation earlier by receiving the information on the occurrence of the earthquake in advance, and the safety of the passengers Can be secured.

  In addition, when there are no passengers in the elevator car, it is possible to appropriately take control operation means such as moving the elevator to a position that is not easily affected by the earthquake, and it is possible to reduce damage to the elevator equipment. .
