Elevator control device

Technical field

[0001] The present invention relates to an elevator control device that detects an occurrence of an earthquake and stops the elevator safely.

Background art

Conventionally, as an earthquake countermeasure for elevators, when an earthquake detector detects an earthquake of a predetermined level or higher, a traveling elevator is automatically stopped at the nearest floor to rescue passengers.

For this reason, a system has been proposed that automatically switches an elevator to seismic control operation when an earthquake is detected, and notifies a maintenance center or the like.

For example, Japanese Patent Laid-Open Publication No. 2004-224469 (see Patent Document 1) receives real-time earthquake information including at least the epicenter and the time of occurrence of an earthquake determined from an earthquake wave and includes the received real-time earthquake information. Information power is shown that predicts the arrival time of an earthquake wave at the current location and controls the elevator's control operation according to the predicted arrival time of the earthquake.

[0003] However, such a control operation system during an elevator earthquake predicts the arrival time and magnitude of an earthquake from real-time earthquake information, and proposes to control the elevator according to the predicted value. Only the details of the control operation control are mentioned!

[0008] Embodiment 1.

As described in Patent Document 1, the present invention uses real-time earthquake information on the arrival time and scale of earthquakes using a high-sensitivity seismic observation network (Hi-Net) promoted by the National Institute for Disaster Prevention Science and Technology. Use. Seismic waves consist of P waves, which are pitch waves (initial motion), and S waves, which are lateral waves (main motion) that propagate later than P waves but cause earthquake damage. At the station, the arrival time of the P wave and the arrival of the P wave are still in use, and the information on the point is used to immediately determine the epicenter and provide the information to the public.

Hereinafter, an embodiment of an elevator control device according to the present invention will be described with reference to the drawings.

FIG. 1 shows a configuration example of an elevator earthquake control operation system according to Embodiment 1 of the present invention. Here, the elevator remote monitoring center 1 is a centralized pipe of a so-called elevator maintenance company. It corresponds to a physical center and is connected via a network 2 to the real-time earthquake information transmitter 3 provided by the aforementioned National Research Institute for Earth Science and Disaster Prevention. This remote monitoring center 1 includes a real-time earthquake information receiver 11 that receives information about P waves transmitted from the real-time earthquake information transmitter 3, a real-time earthquake information received by a telephone line, and a high-speed public line. And a real-time earthquake information transmission device 12 for transmitting to an elevator monitoring device 5 installed in the building by a distribution means 4 such as a dedicated network, wireless, satellite communication or the like.

[0010] In the real-time earthquake information transmitting device 12, distance calculation means 121 for calculating the distance to the epicenter, and from the calculation result of the distance calculation means 121, the epicenter information included in the real-time earthquake information is converted to the epicenter. Distribution priority determining means 122 for distributing in the order close to.

The monitoring device 5 includes an S wave information prediction device 51 that receives the real-time earthquake information transmitted from the elevator remote monitoring center 1 and predicts the arrival time, size, etc. of the S wave information that arrives after the P wave. The elevators 6 and 7 perform the elevator control operation by the elevator control operation control devices 61 and 71 based on the information output from the S wave information prediction device 51.

FIG. 2 shows a flowchart for explaining the operation of the elevator earthquake control operation system according to the first embodiment. Based on FIG. 2, the process flow will be described. If an earthquake occurs at a certain point, the P wave is detected and the time of earthquake occurrence, the location of the epicenter, the magnitude (magnitude), etc. are calculated. It is transmitted to the remote monitoring center 1 via the network 2, such as a line, a dedicated network, or satellite communication. In the remote monitoring center 1, the information is received by the real-time earthquake information receiving device 11, and the reception is confirmed in step S1. When real-time earthquake information is received, the distance calculation means 121 in the real-time earthquake information transmitter 12 calculates the distance to the epicenter of the building from the real-time earthquake information data (step 2), and then determines distribution priority. By means 122, real-time earthquake information is delivered from the epicenter to the building monitoring device 5 with priority given to the building (step S3).

[0012] Upon receiving the real-time earthquake information transmitted from the remote monitoring center 1, the elevator monitoring device 5 predicts the arrival time, size, etc. of the S wave information from the P wave in step S4. Using the S-wave information prediction device 51 to measure, from the above-mentioned real-time earthquake information data, taking into account the distance from the epicenter, the time when the S-wave reaches the building where the elevators 1 and 2 are located and the magnitude of the earthquake at that time Predict things. When the earthquake arrival time and the magnitude of the earthquake are predicted by the S wave information prediction device 51, this information is input to each elevator control operation control device 61, 71, and the control operation control device 61, 71 performs the step S5. Decide how to control the elevator controlled by this equipment according to the time and magnitude of the earthquake.

[0013] For example, if each elevator is in operation, stop at the nearest floor, determine how much to stop, and how long after that the power will return. In the embodiment described above, the power that controls only the elevators 6 and 7 installed in one building can be controlled by elevators installed in a plurality of buildings.

As described above, according to Embodiment 1 of the present invention, the distance to the epicenter of the building is calculated from the real-time seismic information data, and the real-time seismic information is converted to Since it was distributed to the building monitoring device 5 with priority, it is close to the epicenter, that is, the elevator power of the building with a short S wave arrival time can be preferentially dealt with, so emergency control operation can be prevented. Many elevators will be in time, and a more efficient elevator control system in the event of an earthquake can be realized.

[0014] Embodiment 2.

FIG. 3 shows a flowchart for explaining the operation of the elevator earthquake control operation system according to the second embodiment.

In Fig. 3, if an earthquake occurs at a certain point, the P wave is detected and the time of occurrence of the earthquake, the location of the epicenter, the magnitude (magnitude), etc. are calculated. Is sent to the remote monitoring center 1 via the network 2, such as a high-speed public line, a dedicated network, or satellite communication. In the remote monitoring center 1, the real-time earthquake information receiver 11 receives the information and confirms reception in step S1.

[0015] Upon receiving real-time earthquake information, the real-time earthquake information transmitter 12 provides a telephone line. Then, the data is transmitted to the monitoring device 5 via the distribution means 4 such as a high-speed public line or a dedicated network (step S6). In monitoring device 5, the data power of the real-time earthquake information mentioned above also takes into account the distance from the epicenter, the time it takes for the S wave to reach the buildings where elevators 1 and 2 are located, and the magnitude of the earthquake at that time, etc. Is predicted (step S4).

In step S7, the elevator control operation control devices 61 and 62 determine whether the elevator can be stopped at the nearest floor by the predicted arrival time described above, and can stop at the nearest floor by the predicted arrival time. If there is, control operation control is performed on the nearest floor in step S8, and if it cannot be stopped on the nearest floor by the arrival time, the elevator is stopped in step S9 to stop the elevator before the earthquake arrives. Stop suddenly. This makes it possible to stop the elevator when an earthquake arrives, even if the control operation is not in time for the arrival time.

[0016] Embodiment 3.

FIG. 4 shows a flowchart for explaining the operation of the elevator earthquake control operation system according to the third embodiment. In FIG. 4, steps Sl, S6, and S4 are the same as those in Embodiment 2 shown in FIG. Subsequently, in the elevator control operation control devices 61 and 62, in step S10, it is determined whether there is a time allowance until the arrival time predicted in step S4. If there is a time allowance, the process returns to step S1 and predicted. Until the arrival time of the earthquake, the arrival time of the earthquake is sequentially predicted and corrected based on the real-time earthquake information received sequentially. As a result, control operation can be controlled based on more accurate earthquake information.

[0017] Embodiment 4.

FIG. 5 shows a flowchart for explaining the operation of the elevator earthquake control operation system according to the fourth embodiment. In FIG. 5, steps Sl, S6, and S4 are the same as those in the second embodiment shown in FIG. Subsequently, when the earthquake arrival time and the magnitude of the earthquake are predicted by the S wave information prediction device 51, this information is input to each elevator control operation control device 61, 71, and the time until the earthquake arrival in step S5. Depending on the size, it is decided how to control the elevator controlled by this device.

[0018] The elevator control operation control devices 61 and 62 stop the elevator and then go to step S11. Therefore, if it is a large-scale earthquake, it is assumed that aftershocks will continue.

After judging whether the aftershock has settled, a return command is sent. If it is not a large-scale earthquake, in Step 13, it will be self-reset by the elevator control operation control.

As a result, even if aftershocks continue, the elevator can be controlled under the control of control operation, and accurate control operation can be performed.

[0019] Embodiment 5.

FIG. 6 shows a flowchart for explaining the operation of the elevator earthquake control operation system according to the fifth embodiment. In FIG. 6, the steps other than step S14 are the same as those in the fourth embodiment shown in FIG. Elevator control operation control device 61

62, after stopping the elevator, it is judged whether it is a large-scale earthquake in step S11, and if it is a large-scale earthquake, aftershocks are expected to continue. Remote monitoring center 1 sends a low-speed return command until it is determined whether the aftershock has subsided. If it is not a large-scale earthquake, in Step 13, it will be self-returned by the elevator operation control. As a result, even if aftershocks continue, the elevator can be controlled under the control of control operation, and accurate control operation can be performed.
