Abstract

Provided is an elevator control operation system at the occurrence of earthquake, wherein the elevator control operation system is configured to suppress setting costs and can judge the influence of long periodic earthquake. Thus, an elevator control operation system is comprised of an earthquake detector that is set at a building equipped with an elevator, adjusts a detection level of a main swing of the earthquake to detect a long periodic earthquake occurred at the building and outputs an earthquake detection signal; and a control device that predicts the magnitude of the long periodic earthquake or vibration level occurred at the building in accordance with an output condition of the earthquake detector. Hence, no earthquake detectors exclusively used for the detection of long periodic earthquake are required, so that a less expensive system can judge the influence of a long period earthquake.

Description

Elevator seismic control operation system

This invention is particularly effective when a long-period earthquake with a long vibration period occurs in the earthquake control operation for quickly removing passengers in an elevator installed in a building from a car when an earthquake occurs. The present invention relates to an elevator operation control system during an earthquake to ensure passenger safety and minimize equipment damage.

Conventional elevator control systems for earthquakes are equipped with a P-wave seismic detector that detects initial tremors and an S-wave seismic detector that detects major motions. To stop. Further, when an earthquake with a large seismic intensity is detected by the S-wave earthquake detector, the elevator is suddenly stopped.

However, long-period earthquakes with long oscillation periods cannot be detected with the same S-wave seismic detector settings as before. Thus, a system has been proposed that performs an elevator control operation when a long-period earthquake occurs by installing a dedicated long-period earthquake detector that detects long-period earthquakes (see, for example, Patent Document 1).

Also, it is considered to detect long-period earthquakes by adjusting the detection level when outputting the “extra low” earthquake detection signal of the S-wave earthquake detector.

Japanese Unexamined Patent Publication No. 2007-320719

However, the one described in Patent Document 1 has a problem that a dedicated earthquake detector for detecting a long-period earthquake is expensive and installation cost is high. On the other hand, if the detection level when outputting the “extra low” earthquake detection signal of the S-wave earthquake detector is adjusted, the installation cost can be reduced. However, since the detection signal for a long-period earthquake is one point, the operation of the elevator cannot be appropriately determined and switched according to the influence of the long-period earthquake.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an elevator seismic control operation system capable of reducing the installation cost and determining the influence of a long-period earthquake. It is.

The elevator operation control system for an earthquake according to the present invention is provided in a building where the elevator is installed, and detects a long-period earthquake occurring in the building by adjusting the detection level of the main motion of the earthquake. An earthquake detector that outputs a detection signal; and a control device that predicts the magnitude or vibration level of a long-period earthquake occurring in the building based on the output state of the earthquake detection signal by the earthquake detector. It is.

According to the present invention, it is possible to suppress the installation cost of the earthquake control operation system and judge the influence of the long-period earthquake.

Next, the operation of the elevator during the seismic time control operation will be described with reference to FIG.
FIG. 6 is a flow chart for explaining the operation of the elevator seismic control operation system according to Embodiment 1 of the present invention.

First, in step S1, the elevator is operating normally. In this case, the process proceeds to step S <b> 2, and the control device 19 always determines whether or not the earthquake detector 22 outputs an “extra low” earthquake detection signal. If the “special low” earthquake detection signal is not output, the process proceeds to step S3. In step S3, the current elevator operation is continued, and the process returns to step S2. On the other hand, if the “special low” earthquake detection signal is output in step S2, the process proceeds to step S4.

In step S4, it is determined whether or not the earthquake detector 22 is outputting a “low” or “high” earthquake detection signal. When the “low” or “high” earthquake detection signal is output, the process proceeds to step S5. In step S5, the elevator control means 21 detects a "low" or "high" earthquake detection signal, the car 5 stops at the nearest floor, and the process proceeds to step S6. In step S6, the operation of the elevator is suspended and the operation ends.

On the other hand, if step S4 “low” or “high” earthquake detection signal is not output, the process proceeds to step S7. In step S7, a long-period earthquake is detected by the elevator control means 21, and the process proceeds to step S8. In step S8, the car 5 stops after traveling to the nearest floor, and proceeds to step S9.

In step S9, the car 5 continues the closest floor stop state, and proceeds to step S10. In step S10, it is detected whether or not the door opening button 12 in the car 5 has been operated. If the door open button 12 is operated, the process proceeds to step S11. In step S11, a door opening operation is performed, and after a predetermined time, the door closing operation is performed. When the car door 10 and the landing door are completely closed, the process returns to step S9.

On the other hand, if the door opening button 12 is not operated in step S10, the process proceeds to step S12. In step S12, the long-period earthquake scale predicting means 24 counts the output duration time of the “special low” earthquake detection signal by the earthquake detector 22, and determines whether or not it continues for a certain period of time. When the output state of the “special low” earthquake detection signal continues for a certain period of time, the process proceeds to step S13.

In step S13, the long-period earthquake magnitude prediction means 24 determines that the long-period earthquake magnitude is large, and the process proceeds to step S14. In step S14, the operation of the elevator is suspended and the operation ends. At this time, the hall and

car notifying devices

9 and 16 notify that the elevator has been put into a resting state.

On the other hand, if the output state of the “special low” earthquake detection signal does not continue for a certain time in step S12, the process proceeds to step S15. In step S15, the long-period earthquake magnitude prediction means 24 determines that the long-period earthquake magnitude is small, and the process proceeds to step S16. In step S16, after the landing and

car notifying devices

9 and 16 notify that the vehicle will travel to the evacuation floor, the car 5 travels to the evacuation floor that is less affected by the long-period earthquake, and proceeds to step S17. In step S17, the operation of the elevator is suspended and the operation ends.

According to the first embodiment described above, the control device 19 predicts the magnitude or vibration level of a long-period earthquake occurring in the building based on the output state of the “special low” earthquake detection signal from the earthquake detector 22. To do. Specifically, the control device 19 predicts the magnitude or vibration level of a long-period earthquake occurring in the building based on the output duration of the “extra low” earthquake detection signal from the earthquake detector 22. For this reason, the installation cost of the earthquake control operation system can be suppressed, and the influence of a long-period earthquake can be determined.

If the control device 19 predicts that the magnitude or vibration level of a long-period earthquake occurring in the building is larger than a preset threshold value, the control device 19 stops the elevator car 5 at the nearest floor and stops the elevator. Put it in a state. When the control device 19 predicts that the magnitude or vibration level of the long-period earthquake occurring in the building is smaller than a preset threshold, the elevator car 5 is stopped at the nearest floor, and then the long-period earthquake is stopped. Drive to an evacuation floor that is pre-determined as a floor that is less affected by the earthquake.

Therefore, it is possible to operate the elevator according to the scale of the long-period earthquake. Accordingly, it is possible to safely get off the user in consideration of the scale of the long-period earthquake and the like. In addition, it is possible to prevent damage to the equipment in the hoistway due to the elevator rope being caught or swung.

In addition, the landing and

car notification devices

9 and 16 put the elevators in a dormant state when the control device 19 predicts that the magnitude or vibration level of a long-period earthquake occurring in the building is greater than a preset threshold value. Inform the effect. Also, the landing and

car notifying devices

9 and 16 are located near the elevator car 5 when the control device 19 predicts that the magnitude or vibration level of a long-period earthquake occurring in the building is smaller than a preset threshold value. After stopping at the floor, it is notified that the vehicle will travel to the evacuation floor.

For this reason, the user can confirm the operation of the elevator during a long-period earthquake. Thereby, a user's anxiety is reduced.

In the first embodiment, the control device 19 predicts the magnitude or vibration level of a long-period earthquake that has occurred in a building based on the output duration of the “extra low” earthquake detection signal from the earthquake detector 22. Met. However, the control device 19 stores in advance the vibration characteristic information determined by the structure of the building, and based on the vibration characteristic information and the output duration of the “extra low” earthquake detection signal, the magnitude of the long-period earthquake occurring in the building or It is good also as a structure which estimates a vibration level. In this case, it is possible to appropriately determine the influence of the long-period earthquake for each building.

As described above, according to the elevator operation control system for an earthquake according to the present invention, the installation cost can be suppressed and the elevator can be used for judging the influence of a long-period earthquake.
