Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator seismic control operation system before and after seismic waves arrive during an earthquake.
[0002]
[Prior art]
When an earthquake occurs in a certain area, it is necessary to stop the elevators in that area.Earthquake detectors are installed in each building, and when an earthquake is detected, the elevators are automatically switched to seismic control operation and the maintenance center is operated. There is a system to notify such. There is also known a system that can reliably detect even if the number of earthquake sensors installed in each of the buildings where the elevators are installed is reduced or the number of earthquake sensors is reduced (see Patent Documents 1 and 2).
[0003]
However, all of the conventional elevator control operation systems perform the earthquake control operation for the first time after detecting that an earthquake has actually occurred. Therefore, in the case where an earthquake occurs while the elevator is running, there are times when it is necessary to continue running even if the inside of the hoistway is damaged by the earthquake. In addition, even if the nearest floor is landed by an earthquake control operation, the nearest floor is not always a safe floor for earthquakes. Sometimes she was confused to evacuate.
[0004]
In addition, when an earthquake is detected using only an earthquake sensor as in the past, the earthquake control operation is performed even for an earthquake of a size that does not need to be originally controlled due to the overreaction of each earthquake sensor. In some cases, it was lost. Therefore, the conventional elevator control operation system could not control the elevator sufficiently.
[0005]
In any case, it is important to know that an earthquake is coming as soon as possible, and it is also important to accurately detect the magnitude of the earthquake. Driving can be performed.

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
One of the features of the present invention resides in that real-time earthquake information is used when controlling an elevator. This real-time earthquake information system uses the High Sensitivity Earthquake Observation Network (Hi-Net) developed and promoted nationwide by the National Research Institute for Earth Science and Disaster Prevention, and provides information on the arrival time and magnitude of an earthquake in advance. It is a system that can provide the offer.
[0012]
Seismic waves propagate underground and spread, and there are two types of seismic waves: P waves and S waves. The S wave propagates slowly but is a rolling wave (main motion) that causes earthquake damage. The P wave propagates faster than the S wave, but the vibration amplitude is smaller than the S wave. It is. The Disaster Prevention Research Institute of Science and Technology is developing a method to immediately determine the epicenter using the arrival time of P-waves and data at points where P-waves have not yet arrived. With this information, the time and magnitude of the upcoming earthquake can be known before the main motion (P wave) of the earthquake arrives with a margin as the distance from the epicenter increases. In the present invention, the control operation of the elevator is performed by detecting the P wave.
[0013]
Another feature of the present invention is that not only the above-mentioned real-time earthquake information but also a conventionally used earthquake detector is used together.
[0014]
Hereinafter, an embodiment of an elevator seismic control operation system according to the present invention will be described with reference to the drawings.
[0015]
FIG. 1 shows a configuration example of an elevator earthquake control operation system according to an embodiment of the present invention. The elevator seismic control operation system 11 is connected to a real-time earthquake information transmitting device via a network (not shown), and receives real-time earthquake information transmitted from the real-time earthquake information transmitting device, that is, information on P-waves. A real-time earthquake information receiving device 12, a seismic sensor 13 installed in each elevator, an elevator control unit 14 for controlling an elevator based on an output of the seismic sensor 13 and an output from the real-time earthquake information receiving device 12. And an elevator controlled by the elevator control unit 14, which is actually an elevator car 15.
[0016]
The real-time earthquake information receiving device 12 includes a real-time earthquake information receiving unit 16 that receives earthquake information from a real-time transmitting device, and an earthquake magnitude detecting unit 17 that detects the magnitude of an earthquake from the real-time received information received by the receiving unit 16. ing.
[0017]
The elevator control unit 14 determines how to control the elevator car 15 based on the magnitude of the earthquake detected by the earthquake magnitude detection unit 17 and the seismic intensity of the earthquake detected by the earthquake detector 13.
[0018]
Next, the operation of the elevator earthquake control operation system 11 will be described with reference to FIG.
[0019]
When the system 11 is started, it is constantly monitored in step S201 whether the real-time earthquake information transmitted from the real-time earthquake information transmitting device has been received. When the real-time earthquake information receiving unit 16 receives the real-time earthquake information, the process proceeds to step S202, where the earthquake magnitude detecting unit 17 knows the magnitude of the earthquake that has occurred from the received real-time received information and determines whether the magnitude of the earthquake control operation is necessary. to decide.
[0020]
If it is determined in step S202 that the elevator is not large enough to require the earthquake control operation, the process proceeds to step S203, and the elevator control unit 14 in FIG. 1 controls the elevator car 15 to continue the normal operation. I do. Next, in step S204, the earthquake arrives at the elevator, and in the next step S205, the actual seismic intensity of the earthquake in the elevator is sensed by the earthquake sensor 13 installed in the elevator.
[0021]
In the next step S206, the elevator control unit 14 determines whether the seismic intensity of the earthquake detected by the earthquake detector 13 is such that the seismic control operation is required. If the earthquake is such that the seismic intensity is large enough to require the seismic control operation, the elevator control unit 14 controls the elevator car 15 to start the seismic control operation in step S207. On the other hand, if the seismic intensity of the earthquake is not so large as to require the control operation in step S206, the process proceeds to step S208 and normal operation is continued.
[0022]
On the other hand, in step S202, when the magnitude of the earthquake detected from the real-time earthquake information is large enough to require the earthquake control operation, the process proceeds to step S210 to detect whether the elevator car 15 is running. If the elevator car is not running, the process moves to step S211 and the operation of the elevator is paused for a while.
[0023]
If it is detected in step S210 that the elevator car is running, it is determined in next step S212 whether there is time to go straight to the nearest evacuation floor. Specifically, the time required for the earthquake to arrive at a certain point from the earthquake occurrence point and the earthquake occurrence time, which is included in the received real-time earthquake information, is calculated. The evacuation time required for passengers to evacuate will be compared. The evacuation time refers to the time from when the elevator car goes straight to the nearest evacuation floor, when the elevator car reaches the floor, when the elevator is running, and when the door is opened.
[0024]
If the evacuation time is shorter than the earthquake arrival time, it is possible to go to the evacuation floor before the earthquake, so in the next step S213, go straight to the evacuation floor and open the elevator door. Then, the passengers of the elevator can evacuate. In the subsequent step S214, the earthquake reaches the elevator, and in step S215, the actual seismic intensity is sensed by the earthquake detector 13 grounded to the elevator. The seismic intensity information of this earthquake is sent to the elevator control unit 14, and in step S216, it is determined whether or not the seismic intensity of the elevator requires seismic control operation.
[0025]
If the seismic intensity measured by the earthquake sensor 13 is large enough to actually require the earthquake control operation, the operation of the elevator is suspended for a while in step S217. On the other hand, when the seismic intensity is not large enough to require the earthquake control operation, the normal operation is restarted in step S218.
[0026]
By the way, in step S212, when it is estimated that the arrival time of the earthquake is shorter than the above-mentioned evacuation time and it is not possible to go to the evacuation floor and evacuate the passengers before the earthquake, the process proceeds to step S220, and the elevator controller 14 controls the elevator car 15 to start the earthquake control operation.
[0027]
When the earthquake arrives in step S221, the seismic intensity of the actual earthquake is detected by the earthquake detector 13 installed in the elevator in the next step S222, and in step S223, it is determined whether the earthquake is large enough to require the earthquake control operation. Judge. If the earthquake is so large that the earthquake control operation is necessary, the earthquake control operation is continued in step S224.
[0028]
On the other hand, if the seismic intensity is not so large in step 223, the elevator control unit 14 controls the elevator car 15 and starts normal operation in step S225.
[0029]
According to this embodiment of the present invention, instead of performing the elevator seismic control operation only by real-time earthquake information, it is determined whether to perform the seismic control operation in consideration of the seismic intensity of the subsequent actual earthquake, Accurate and reliable elevator seismic control operation can be performed.
[0030]
By the way, according to the present invention, after obtaining real-time earthquake information, it is also possible to notify a person waiting for a passenger elevator of the elevator of the information of the occurrence of the earthquake.
[0031]
Next, another embodiment of the present invention will be described with reference to FIG. The process is the same as that of the above embodiment until the elevator control unit obtains information about the earthquake from the real-time earthquake information receiving device and the earthquake sensor.
[0032]
The elevator control guidance unit 31 includes an earthquake notification control unit 33 in addition to the elevator control unit 32 that controls the elevator car. In addition, an in-car alarm 35 is installed at an easily-viewable upper portion of the elevator car 34, and a hall alarm 37 is also installed at an easily-viewable position of the elevator hall 36. The in-car alarm 35 and the landing alarm 37 are made up of a speaker and a display. Earthquake information from the earthquake alarm controller 33 is announced and displayed by these alarms.
[0033]
The elevator control unit 32 controls the elevator car 34 based on the earthquake magnitude information included in the real-time earthquake information from the real-time earthquake information receiving device and the seismic intensity obtained from the earthquake detector 38, for example, as described in the above embodiment. Control.
[0034]
On the other hand, based on the received real-time earthquake information, the estimated time at which the earthquake arrives at the elevator location, the estimated seismic intensity, and the like are announced and displayed by the in-car alert device 35 and the landing alert device 37. The displays of the in-car alarm 35 and the landing alarm 37 can also display an evacuation site near the elevator and a route to the site, and can also announce them.
