Description

  The present invention relates to a seismic control operation system for an elevator that ensures the safety of passengers and minimizes damage to hoistway equipment and the like before the earthquake reaches the elevator.

  In a conventional elevator seismic control operation system, a P-wave seismic detector that detects the occurrence of initial tremors of an earthquake or an S-wave seismic detector that detects the main motion of an earthquake is installed, and when the seismic sensor operates, When the elevator is stopped at the nearest floor, or when an earthquake with a large seismic intensity is detected by the S-wave seismic detector, the earthquake control operation is performed such that the elevator stops suddenly.

  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 delivered from the management base, thereby causing the elevator to perform the control operation. There is 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, in the seismic control operation system, 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 transmitted via the Internet. There is also known an elevator seismic control operation system that distributes and obtains earthquake information in advance so that passengers are taken off from the car at the evacuation floor or the nearest floor before the earthquake wave arrives (see, for example, Patent Document 2) ).

  In the conventional elevator seismic control operation system, since seismic control operation is performed after the operation of the seismic detector, there is a seismic motion, the equipment in the hoistway collides, and the rope vibrates violently. Even had to move the elevator. Therefore, there is a risk of causing damage to the rails and the equipment in the hoistway.

  In addition, the seismic control operation system using the Internet distribution of earthquake information controls the elevator control operation based on the predicted arrival time of the seismic wave included in the earthquake information when the earthquake information is received. The accuracy of the arrived arrival time may be reduced in transmission line delays, large-scale earthquakes, earthquakes with deep epicenters, etc., and it is not always guaranteed that the information is accurate. For example, if the actual arrival time of the seismic wave is earlier than the expected arrival time, the elevator determines that there is a margin until the earthquake arrival time and continues operation. However, if the seismic wave arrives at that time, the above-described problems may occur.

  The present invention was made to solve the above-described problems. When an earthquake occurs, the safety of passengers is ensured before the earthquake reaches the elevator, and damage to hoistway equipment and the like is prevented. The present invention provides an elevator seismic control operation device that can be minimized.

In the elevator seismic control operation system according to the present invention, the earthquake information receiving means for receiving the emergency earthquake warning distributed via the communication means, and the information included in the emergency earthquake warning received by the earthquake information receiving means can be arbitrarily selected. An earthquake information predicting means for predicting an initial microtremor arrival predicted time and a main motion estimated arrival time at the point, and an elevator control means for controlling the elevator during an earthquake based on the predicted predicted main motion arrival time by the earthquake information predicting means, Compared with the P-wave seismic detector installed in the elevator that detects the initial tremor of the earthquake, the time when the P-wave seismic detector detected the initial tremor and the expected initial tremor arrival time from the earthquake information prediction means, P wave earthquake detection with earthquake information correction means for correcting the predicted arrival time of the main motion predicted by the earthquake information prediction means based on the prediction error When is not operating, the elevator control means calculates the surplus time until the main motion occurs from the predicted arrival time of the main motion predicted by the earthquake information prediction means, and selects the stop operation according to the surplus time When performing seismic control operation using the predicted arrival time of main motion and selecting seismic control operation using the expected arrival time of main motion, the current elevator operation is stored in the elevator control means as the control operation operation due to main motion. If the earthquake early warning is not received, the seismic control operation at the predicted main motion arrival time is continued, and when the P-wave seismic detector is operated, the corrected main motion prediction is corrected by the earthquake information correcting means. The time is calculated, the margin time to the main motion arrival time is calculated based on the corrected main motion estimated arrival time, and the stop main motion is selected according to the margin time. Time is performed the earthquake control operation operation using the.

  According to the present invention, it is possible to improve the accuracy of the arrival time of the main motion required from the earthquake early warning, and more accurately determine the surplus time until the arrival time of the seismic wave, thereby realizing a more appropriate and reliable elevator operation during earthquakes. It is possible to reduce elevator safety and damage to hoistway equipment and the like.
