In the event of an earthquake, the most important thing to do to prevent a disaster is to quickly evacuate passengers from the elevator. Passengers must be evacuated by landing on the floor. Earthquakes generally consist of P waves (initial tremors) with high propagation speed and S waves (main shock, main shaking) with large vibrational energy.
There are two types of characteristics: seismic control operation of elevators takes advantage of these characteristics, and there are S-wave sensing earthquake control operation and P-wave sensor-equipped earthquake control operation. Typically, S-wave sensing seismic control operation is used, and a flowchart of an example of this operation method is shown in FIG. Earthquake control operation with a P-wave detector adds a P-wave detector to the operation method shown in the flowchart shown in Figure 1, so that when a P-wave with a high propagation speed is detected in the early stages of an earthquake, the elevator is moved to the nearest location. This is a method of stopping the vehicle on the floor and returning to normal operation if the S-wave sensor does not operate even after a certain period of time has elapsed.

In the earthquake control operation E mentioned above, in the S-wave sensing earthquake control operation, it is thought that there are few problems with low-speed operation elevators (for low floors), but the elevator is not allowed to land until the stop signal from the nearest floor is issued. In high-speed elevators that require a long operating time (elevators that require a long deceleration distance), the deceleration distance of several floors is required from receiving the earthquake sensor operation signal until the elevator reaches the floor. However, it is difficult to ensure that the train stops at the nearest floor. Furthermore, it is extremely dangerous to run the elevators after the main shock is detected and could lead to a serious disaster. In earthquake control operations with P-wave detectors, in order to detect P-waves (initial tremors), even if the vibration is at a level that does not actually require stopping the elevator, the elevator is always stopped in one phase, so elevator service is required. There is a problem in that the value decreases.

In order to achieve the above object, the present invention installs an earthquake sensor for detecting initial minute vibrations when an earthquake occurs and an earthquake sensor for detecting the main shock in a restriction device for an elevator with earthquake control operation. When vibration is detected, the elevator's running speed is switched from high to low and operation continues, and when the main shock is detected, the elevator is moved from the low speed to the nearest floor, and the main shock is continued even after a predetermined period of time has passed. If there is no detection, the running speed of the elevator is returned to high speed operation.

When a minute vibration in the initial stage after an earthquake is detected by the minute vibration sensor 1 shown in FIG. 2, the low speed running command relay 3 is energized from P-1-9-31 in FIG. 33a #3-4b, the input signal to the speed pattern generator 5 is switched from high-speed running to low-speed running. A speed pattern for low-speed running is output from the speed pattern generator No. 5, and the elevator starts operating at low speed. The low speed operation is continued by P-4-1b-3-1a-3 until the normal operation return timer 4 times out. When the micro-vibration sensor l no longer detects vibration, the normal operation recovery timer 4 starts counting time according to P-3-2a-2-1b-4, and depending on the arrival time difference and arrival intensity between the initial micro-vibration and water damage, After a predetermined period of time (approximately 10 seconds), the controller 4-1b1 resets the low-speed running command relay 3 and returns the elevator to normal operation. When the earthquake detector (not shown) that detects water damage is activated while the normal operation recovery timer 4 is counting,
Earthquake control operation for stopping at the nearest floor is performed in accordance with the flowchart shown in FIG. 1 in the same manner as has been done in the past. (Circuit diagram not shown.) Effects of the Invention] As explained above, according to the present invention, if an earthquake occurs while the elevator is running at high speed, the elevator can be switched from high speed operation to low speed operation upon detecting initial minute vibrations. By switching to , it is possible to ensure that the elevator will land at the nearest floor when the main shock is detected, and prevent elevator disasters in the event of an earthquake. In addition, when detecting minute vibrations, if the vibration is at a level that does not require stopping, the elevator will be operated at low speed without stopping, and if the main shock is not detected after a certain period of time, the elevator will be operated at high speed. By putting it back, elevator service can be improved.
