Description

  The present invention relates to an elevator operation control device, an elevator operation control method, and an elevator operation control program.

The Japan Meteorological Agency started operation of the Earthquake Early Warning from August 1, 2006. This is a system that catches the initial tremor of an earthquake and notifies the occurrence of an earthquake before a strong shake occurs. When an occurrence of an earthquake of a predetermined size or larger is detected at an observation point of the Japan Meteorological Agency or another organization, a specific operator Emergency earthquake bulletin is sent to.
Since October 2007, it has also been sending bulletins to general individuals. A system that processes earthquake early warning data received from the Japan Meteorological Agency, predicts seismic intensity in multiple specific areas, and broadcasts and pays secondary distribution has also started operation.
The transmission data of the earthquake early warning includes information on the time of earthquake occurrence, the position of the epicenter, and the magnitude of the earthquake. Of the three-dimensional position information of the epicenter, the two-dimensional position data excluding the information of the epicenter depth is hereinafter referred to as epicenter information.

Non-Patent Document 1 discloses an alarm system uniquely developed by a construction company. The contents of the bulletin are, for example, “Tokyo 23 wards, seismic intensity of about 5 weaker than 12 seconds later”. The non-patent document 1 has segregated seismic intensity for each construction site. presume. The information is transmitted to the related parties after about 2 seconds on an in-house information communication network constituted by a LAN (Local Network) or the like. In addition to being displayed on the construction office PC, the information is also transmitted wirelessly to on-site workers.
The technique disclosed in Non-Patent Document 2 receives an earthquake early warning from a PC (Personal Computer) via the network, and the PC calculates a predicted seismic intensity at the current location. The risk of long-period vibration is determined from the epicenter distance and building conditions. A control ON command issued by the PC is sent to the elevator control panel via the interface. As of June 2006, before the earthquake of seismic intensity 4 or higher, the main building central elevator stops at the nearest floor to prevent “confinement” and the door opens to guide evacuation.
Non-Patent Document 3 discloses a concept of a service for delivering the time to seismic motion and seismic intensity data analyzed by a data center to a home using a CATV (Cable Television) network.
Patent Document 1 discloses an elevator seismic control operation system that performs control operation of an elevator by predicting the time of an earthquake using real-time earthquake information based on earthquake waves.
"Notice before 'Grack', emergency earthquake warning starts operation", Yomiuri Shimbun, August 1, 2006 “Earthquake Early Warning Demonstration System” [online], Disaster Medical Center, [Searched on November 21, 2006], Internet <URL: http: //www.hosp.go.jp/~tdmc/dm_jisinsokuhou.htm> “Earthquake Early Warning” CATV announces predicted seismic intensity JCOM tests in June ”, FujiSankei Business i. March 20, 2007 JP 2004-224469 A (FIGS. 1 and 2)

The area where the earthquake control operation of the elevator according to the earthquake early warning can be started before the arrival of the seismic wave is limited to the area far from the epicenter. This is because (1) the propagation time of the P (Primary) wave from the epicenter to the first observation point by the Japan Meteorological Agency, etc., (2) the time required to communicate with the arithmetic unit of the Japan Meteorological Agency, (3) Calculation time at the Japan Meteorological Agency, (4) Time required for communication from the Meteorological Agency to the receiver for the Earthquake Early Warning, (5) Total time for calculating data necessary for earthquake control operation after receiving the Earthquake Early Warning at the receiver This is because time is required, and the start of the earthquake control operation is not in time for the arrival of the S (Secondary) wave near the epicenter.
Even if the earthquake control operation can be started before the arrival of the S wave, the arrival of the P wave is detected at the site where the elevator is located by another system and the earthquake control operation is started. Even if earthquake control operation is started, the effectiveness of emergency earthquake warning is small.
For this reason, it is desirable that the area where the seismic control operation can be started before the arrival of the seismic wave is close to the epicenter and covers an area where serious damage is a concern. For this purpose, in addition to shortening the time required to transmit the bulletin, it is required to shorten the calculation processing time in the receiving side device as much as possible.

In the system of Non-Patent Document 1, calculation of the predicted seismic intensity at each construction site of the company is performed by the centralized management device installed at one specific location, so the installation cost can be reduced. There is a problem that it takes about 2 seconds from receiving the earthquake early warning to transferring information to each construction site.
In the system of Non-Patent Document 2, it is necessary to install a dedicated PC in each building that has an advanced calculation function that determines the risk of long-period vibration from the epicenter distance and building conditions, etc. There's a problem.
In the system of Non-Patent Document 3, when the output signal is used in the elevator, it is not necessary to calculate the predicted seismic intensity at the elevator location. However, (a) the calculation / inference processing time and the second The delay time increases due to the addition of the next transmission time. (B) Appropriate judgment cannot be made according to the characteristics of the building, ground conditions, and elevator specifications. (C) There are problems such as maintaining secondary distribution lines or paying contract fees to be paid to contractors.

  Furthermore, if the operator who manages the elevator installs the emergency earthquake warning receiving equipment and the hardware for centralized calculation processing in a remote location and the hardware and the operation control device of each elevator communicate with each other, more processing time will be required. There is a concern that it will be necessary. Therefore, it is conceivable to install hardware in each of the elevator operation control devices scattered in various places, or in each building where the elevator is installed. At that time, there was a great demand for a simple and inexpensive configuration with a high-speed calculation function.

However, in the control operation system described in Patent Document 1, no consideration is given to this point, and means for predicting the arrival time of the seismic wave is an essential component. The prediction calculation of the arrival time of the seismic wave requires calculation of a two-dimensional or three-dimensional distance from the epicenter to the elevator, and these distance calculations include a square root operation. Since the square root calculation requires a relatively long time, any measure of installing hardware capable of high-speed calculation processing is necessary.
On the other hand, long-period seismic waves of earthquakes with large magnitude values are the main ropes of elevators installed in high-rise buildings, etc. with a time delay of several minutes in an area about several hundred kilometers away from the epicenter rather than near the epicenter. It is known that large lateral vibration is generated in an object having a low natural frequency such as. The occurrence example of the failure in which the main rope is entangled with the equipment installed in the hoistway due to the rolling is confirmed. However, the control operation system of Patent Document 1 does not consider the avoidance of elevator damage due to long-period seismic waves.

The present invention has been made in view of such a background, and an object of the present invention is to enable an earthquake control operation of an elevator at a low cost and at a high speed by a simple algorithm.

  In order to solve the above problems, the present invention has been completed. That is, the present invention obtains, from an external device, at least an earthquake occurrence position information that is information on the position of the earthquake occurrence point and an earthquake magnitude value, and position information that is information on the position of the elevator operation control device itself, The elevator control operation is determined based on the occurrence position information and the magnitude value, and is long if the epicenter is outside the predetermined area close to the elevator installation location and the magnitude value is greater than the threshold value. It has a processing part which performs control corresponding to a periodic earthquake.

  According to the present invention, an earthquake control operation of an elevator can be performed at low cost and at high speed by a simple algorithm.

Next, the best mode for carrying out the present invention (referred to as “embodiment”) will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a diagram illustrating a configuration example of an elevator operation control system according to the first embodiment. In the first embodiment, the earthquake control operation of the elevator is performed using, as the earthquake occurrence position information, the position of the epicenter excluding the depth information from the information on the position of the epicenter.
The elevator operation control system 1 receives an emergency earthquake warning from the elevator 3 and an emergency earthquake warning transmission server (external device) installed in the Japan Meteorological Agency 5, and operates the elevator 3 based on the received emergency earthquake warning. And an elevator operation control device 2 for controlling the vehicle. The elevator operation control system 1 is installed in a building 4. The elevator operation control device 2 is installed for each elevator 3. Here, the earthquake early warning includes the epicenter position (longitude and latitude), the depth of the epicenter, the M (Magnitude) value, the predicted maximum seismic intensity, the earthquake detection time, and the like.
The elevator operation control device 2 has the following configuration.
The receiving unit 23 receives the emergency earthquake bulletin transmitted from the Japan Meteorological Agency 5, and sends the epicenter position (longitude and latitude), the depth of the epicenter, and the M value in the data included in the emergency earthquake bulletin to the processing unit 21. It has a function. The receiving unit 23 includes, for example, an antenna installed outside the building and a receiving device that is provided in the elevator operation control device 2 and is connected to the antenna and acquires information received by the antenna.
The storage unit 22 includes episeismic region division information 222 (region division information) which will be described later with reference to FIG. 2 and building position information 221 (position information) which is position information of the building 4 where the elevator operation control device 2 is installed. It has. The building position information 221 stores the position of the building 4 as two-dimensional information of longitude and latitude. In addition, the position of the elevator operation control device 2 itself in the claims refers to the position of the building 4 in this example.

  In the processing unit 21 and the input unit, an elevator operation control program stored in an HD (Hard Disk) or ROM (Read Only Memory) is developed in a RAM (Random Access Memory) or the like, and a CPU (Central Processing Unit). It is embodied by being executed by.

FIG. 2 is a diagram illustrating an example of epicenter region division information according to the first embodiment. In the first embodiment, the epicenter region classification information 222 is obtained by classifying the surface area or sea surface area in the vicinity of Japan into the following four groups of two or more primary inequalities using numerical values of latitude and longitude. Define.
In FIG. 2, the position of the building 4 is indicated by P, and the position of the epicenter is indicated by E. In the following inequality, Λ represents the longitude of the epicenter, and Φ represents the latitude of the epicenter. Furthermore, λ indicates the longitude of the position of the building 4, and φ indicates the latitude of the position of the building 4.

First, epicenter E
| Λ−λ | ≦ 1 ° and | Φ−φ | ≦ 1 ° (1)
It is assumed that the epicenter E exists in the area section A when it is in the area section.
Similarly, epicenter E is
1 ° <| Λ−λ |, or 1 ° <| Φ−φ |, and | Λ−λ | ≦ 2.5 °, and | Φ−φ | ≦ 2.5 ° (2)
It is assumed that the epicenter E exists in the regional segment B when it is in the regional segment.
Also, epicenter E is
2.5 ° <| Λ−λ |, or 2.5 ° <| Φ−φ |, and | Λ−λ | ≦ 4 °, and | Φ−φ | ≦ 4 ° (3)
It is assumed that the epicenter E exists in the area section C when it is in the area section.
And, when the epicenter does not exist in any of the regional sections A to C, that is, the epicenter E is 4 ° <| Λ−λ |, or 4 ° <| Φ−φ | (4)
It is assumed that the epicenter E exists in the area division D when it is in the area division.

In FIG. 2, the area section A corresponds to the area inside the smallest square centered on the position P of the building 4. The area section B corresponds to an area outside the smallest square and inside the next smallest square. In addition, the area section C corresponds to an area outside the next smallest square and inside the largest square, and the area section D is outside the largest square.
That is, the episeismic region division information 222 is divided into concentric rectangular regions around the position of the building 4 where the elevator operation control device 2 is installed, and the epicenter location included in the emergency earthquake bulletin is the region division. The information that becomes one of the determination criteria for the elevator operation control device 2 to adjust the earthquake control operation of the elevator 3 depending on where it falls.

Here, the relationship between the epicentral region division information 222, the M value, and the earthquake control operation of the elevator 3 will be described.
Based on the epicenter region classification information 222 set by the method described above and the received M value, the elevator operation control device 2 determines the necessity of the earthquake control operation of the elevator 3 by the following determination formula. It should be noted that the epicentral region classification, the M value, and the earthquake operation control of the elevator 3 shown here are examples, and other combinations are naturally conceivable.
If the epicenter is in region A,
When M value ≥ 3.0, current seismic control operation is performed, long-period earthquake control operation is not performed. When M value <3.0, current seismic control operation is not performed, long-period earthquake control operation is not performed. If in category B,
When M value ≧ 4.5, seismic control operation is performed for the time being, long-period seismic control operation is not performed. If in category C,
When M value ≥ 6.0, conduct earthquake control operation for the time being,
And, it is determined whether or not long-period earthquake control operation is necessary (by the actual frequency component of vibration). When 6.0 ≧ M value ≧ 5.5, the current earthquake control operation is performed, and the long-period earthquake control operation is not performed. .5, seismic control operation is not performed for the time being, long-period seismic control operation is not performed.
Regardless of the M value, immediate earthquake control operation is not performed, long-period earthquake control operation is not performed

In the first embodiment, the operation of the elevator 3 when the earthquake control operation (the earthquake control operation or the earthquake control operation) is performed is basically as follows.
1. If the car is stopped and the door is open, maintain that state.
2. When the car is stopped and the door is closed, when the door is being closed, or when the door is being opened, the door is opened, and the state is maintained after the opening operation is completed.
3. When the car is moving, it is landed on the nearest floor where it can be stopped in the direction of travel, the door opening operation is performed, and the state is maintained after the door opening operation is completed.
In addition, the long-period earthquake control operation determines whether there is a possibility that the main rope, the balancing rope (compensation rope), the governor rope, or the tail cord of the elevator 3 may vibrate at low frequency and interfere with the components provided in the hoistway. This is an operation method in which the vibration frequency component is estimated based on the actual measurement value of the vibration, and when it is estimated that there is the risk, the operation is stopped in a predetermined position or in a predetermined area, and is an earthquake control operation in a long-period earthquake.

Next, the operation of the elevator earthquake control method by the elevator operation control device 2 according to the first embodiment will be described along FIG. 3 with reference to FIGS. 1 and 2.
FIG. 3 is a flowchart showing a flow of the elevator operation control method according to the first embodiment.
First, the receiving unit 23 receives an emergency earthquake bulletin from the Japan Meteorological Agency 5 (S1), and at least the epicenter position information, the epicenter depth, and the M value, which are information of the epicenter position, are processed from the received emergency earthquake bulletin. Hess.
Next, when the processing unit 21 acquires the building position information 221 from the storage unit 22, the processing unit 21 calculates values of | Λ−λ | and | Φ−φ | (S2). Here, Λ, λ, Φ, and φ have the same meaning as the symbols used in FIG.
Next, the processing unit 21 determines whether or not the value calculated in step S2 corresponds to the region classification A described with reference to FIG. 2 (S3).
And when it determines with corresponding to the area classification A by the process part 21 (S3-> Yes), the process part 21 is 3.0 or more whether the M value (M) contained in the earthquake early warning is 3.0 or more. It is determined whether or not (S4).
When the processing unit 21 determines that the M value is smaller than 3.0 (S4 → No), the processing unit 21 does not perform the immediate earthquake control operation of the elevator 3 (not implemented: S10).
When the processing unit 21 determines that the M value is 3.0 or more (S4 → Yes), the processing unit 21 performs an immediate earthquake control operation of the elevator 3 (S12).

Returning to the description of the processing in step S3.
When the processing unit 21 determines that the region does not correspond to the region classification A (S3 → No), the processing unit 21 determines whether the value calculated in step S2 corresponds to the region classification B described with reference to FIG. It is determined whether or not (S5).
When it determines with corresponding to the area division B by the process part 21 (S5-> Yes), the process part 21 determines whether the M value contained in the earthquake early warning is 4.5 or more. (S6).
When the M value is determined to be smaller than 4.5 by the processing unit 21 (S6 → No), the processing unit 21 does not perform the current earthquake control operation of the elevator 3 (S10).
When the M value is determined to be 4.5 or more by the processing unit 21 (S6 → Yes), the processing unit 21 performs an immediate earthquake control operation of the elevator 3 (S12).

Returning to the description of the processing in step S5.
If the processing unit 21 determines that the region does not correspond to the region classification B (S5 → No), the processing unit 21 determines whether the value calculated in step S2 corresponds to the region classification C described with reference to FIG. It is determined whether or not (S7).
If it is determined by the processing unit 21 that the region category C is applicable (S7 → Yes), the processing unit 21 determines whether the M value included in the emergency earthquake warning is 6.0 or more. (S21). When the processing unit 21 determines that the M value is smaller than 6.0 (S21 → No), the processing unit 21 determines whether the M value included in the emergency earthquake warning is 5.5 or more. Is determined (S8). When the processing unit 21 determines that the M value is 6.0 or more (S21 → Yes), the processing unit 21 performs an immediate earthquake control operation of the elevator 3 (S12) and has a long cycle. The necessity of earthquake control operation is determined (S22). When it is determined that the long-period earthquake control operation is necessary (S22 → Yes), the processing unit 21 performs the long-period earthquake control operation after the current earthquake control operation in Step S12 (S23). If it is determined that the long-period earthquake control operation is not possible (S22 → No), the process is terminated.
In step S8, when the processing unit 21 determines that the M value is smaller than 5.5 (S8 → No), the processing unit 21 does not perform the immediate earthquake control operation of the elevator 3 (S10).
When the processing unit 21 determines that the M value is 5.5 or more (S8 → Yes), the processing unit 21 performs an immediate earthquake control operation of the elevator 3 (S12).

Returning to the description of the processing in step S7.
When the processing unit 21 determines that the region classification does not correspond to C (S7 → No), the processing unit 21 determines that the region classification where the epicenter exists corresponds to the region classification D (S9), and the M value. Regardless of the value of, the current earthquake control operation of the elevator 3 is not performed (S10). This is because it is considered that the building 4 is not greatly shaken even if the distance is long, for example, a huge earthquake, and unnecessary operations are prevented.
In addition, the P wave detection unit (not shown) of the elevator operation control device 2 detects the P wave exceeding the preset threshold value before receiving the earthquake early warning or each process from Step S2 to Step S9 is completed. When performed (S11), the processing unit 21 performs an immediate earthquake control operation of the elevator 3 regardless of the regional division of the epicenter and the value of the M value (S12).

In addition, a predicted maximum seismic intensity calculation table showing the relationship between the M value and the predicted maximum seismic intensity that is the maximum predicted seismic intensity in the building 4 is set in advance for each region, and this predicted maximum seismic intensity calculation table is stored. You may store in the part 22. FIG.
In this case, after step S <b> 3, the processing unit 21 refers to the predicted maximum seismic intensity calculation table corresponding to the region classification A stored in the storage unit 22 and acquires the predicted maximum seismic intensity. And in the process of step S4, the process part 21 determines whether an earthquake control driving | operation is implemented by whether the acquired estimated maximum seismic intensity is more than a predetermined threshold value. The same processing is performed for other regional sections. Note that the predetermined threshold value is different for each region.

  Furthermore, based on the number of floors of the building 4 in which the elevator operation control device 2 is installed, the ascending / descending stroke of the elevator 3, the ground strength that is the strength of the ground on which the building 4 is built, etc. An angle constant may be set in advance. If the degree of susceptibility to the long-period earthquake in the area where the building 4 is built is known, the necessity of the long-period earthquake control operation is determined in consideration of the data.

According to the present embodiment, it is possible to perform the earthquake control operation of the elevator 3 when an earthquake occurs without using the predicted arrival time of the emergency earthquake warning.
In particular, the earthquake control operation of the elevator 3 can be performed regardless of the expected arrival time of the S wave.
In addition, according to the present embodiment, the elevator operation control device 2 can determine whether or not the earthquake control operation is necessary by executing simple four arithmetic operations, absolute values, and condition determination, and the processing time is shortened. That is, when calculating the linear distance from the epicenter to the building, the square root calculation with a large processing load must be used, but according to this embodiment, it is determined whether or not the earthquake control operation is necessary without using the square root calculation. Is possible.
Therefore, the earthquake control operation of the elevator 3 can be started earlier, and the present embodiment can be applied even in an area where the seismic wave arrives closer to the epicenter. That is, the elevator operation control system 1 according to the present embodiment can cover an area that is close to the epicenter and in which serious damage is a concern.
Furthermore, as described above, since simple four arithmetic operations, absolute values, and condition determination are only executed, the configuration of the elevator operation control device 2 can be simplified, and the cost can be reduced.
Moreover, the function corresponding to the earthquake early warning by this embodiment can be easily added to the control apparatus of the elevator 3 currently installed.

  Moreover, this embodiment can also use the earthquake detection time included in the emergency earthquake warning. In this case, the processing unit 21 calculates an approximate arrival time that is an approximate value of the time at which the S wave arrives at the building 4 from the earthquake detection time included in the emergency earthquake bulletin and the above-described regional segment where the epicenter exists. . If the surplus time obtained by subtracting the current time from the approximate arrival time is less than a predetermined value, the processing unit 21 stops the car at the nearest floor where the car can be stopped, opens the door, waits, and the surplus time is a predetermined value. If it is above, it performs earthquake operation control, such as stopping at a standard floor such as the ground floor, opening the door, and waiting.

Next, with reference to FIG. 4, another example of the epicenter region division information 222 in the first embodiment is shown.
FIG. 4 is a diagram illustrating another example of the epicenter region division information according to the first embodiment.
In the epicenter region information 222 shown in FIG.
| Λ−λ | ≦ 1 °, and | Φ−φ | ≦ 1 °, and | Λ−λ | + | Φ−φ | ≦ 3 °
(5)
It is assumed that the epicenter E exists in the area section A when it is in the area section.
Similarly, epicenter E is
1 ° <| Λ−λ |, or 1 ° <| Φ−φ |, or 1.5 ° <| Λ−λ | + | Φ−φ |
And (| Λ−λ | ≦ 2.5 °, and | Φ−φ | ≦ 2.5 °), and 1.5 ° <| Λ−λ | + | Φ−φ | ≦ 3.5 ° (6)
It is assumed that the epicenter E exists in the regional segment B when it is in the regional segment.
And when the epicenter does not exist in either the area division A or the area division B, that is, the epicenter E is
2.5 ° <| Λ−λ |, or 2.5 ° <| Φ−φ |, or 3.5 ° <| Λ−λ | + | Φ−φ | (7)
It is assumed that the epicenter E exists in the area section C when it is in the area section.

That is, in the example of FIG. 4, the area segment A is in the area inside the small octagon centered on the position P of the building 4, and the area segment B is outside the small octagon and inside the large octagon. The area section C corresponds to the area outside the large octagon.

The relationship between the M value when using the epicentral region division information 222 shown in the example of FIG. 4 and the execution and non-execution of the earthquake control operation of the elevator 3 is, for example, as follows.
If the epicenter is in region A,
When M value ≥ 3.0, current seismic control operation is performed, long-period earthquake control operation is not performed. When M value <3.0, current seismic control operation is not performed, long-period earthquake control operation is not performed. If in category B,
When M value ≥ 5.0, conduct immediate earthquake control operation,
And, the necessity of long-period seismic control operation is judged (by the actual frequency component of vibration). When M value <5.0, the current seismic control operation is not performed and the long-period seismic control operation is not performed. If
Regardless of the M value, the current seismic control operation is not performed and the long-period seismic control operation is not performed. The operation of the elevator 3 when the seismic control operation is performed is the same as the example described with reference to FIGS. To do. Long-period seismic control operation is performed only in the area where the distance from the epicenter E is neither too small nor too large.
Note that the processing in the case of using the epicenter region information 222 shown in the example of FIG. 4 is the same as the processing described in FIG.

It should be noted that the values of M values that are the criteria for seismic control operation for each of the formulas (1) to (7) and the regional divisions are only examples, and in fact, the location of the epicenter, the M value and the current seismic intensity Set after adjustment based on actual data.
When the operation control apparatus receives the output signal of the P-wave sensor after determining whether or not the long-period earthquake control operation is necessary, it is possible to change the necessity determination of the long-period earthquake control operation depending on the result.

According to the present embodiment, by using simple four arithmetic operations, absolute values, and condition determination, the region segment has a shape close to a concentric circle while maintaining the advantage that the processing time can be shortened. The necessity of the seismic control operation in the apparatus 2 has an effect that a more rational and accurate determination can be made than in the example shown in FIG.
Moreover, in this embodiment, as shown in FIG.2 and FIG.4, although area division was made into the rectangular or octagonal mesh shape, you may divide by not only this but the concentric circle of radial direction.
In this embodiment, the epicenter is used as an earthquake occurrence point. However, the present invention is not limited to this, and for example, an epicenter with depth added to the epicenter may be used.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 5 is a diagram illustrating a configuration example of an elevator operation control system according to the second embodiment. In FIG. 5, elements similar to those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
In the elevator operation control device 2a of the elevator operation control system 1a, instead of the epicenter region segment information 222 (see FIG. 1) of the first embodiment, the storage unit 22a includes a rough epicenter distance calculation formula 223 and elevator information 224. Yes.
The elevator information 224 includes the number of floors of the building 4 in which the elevator operation control device 2a is installed, the ascending / descending stroke of the elevator 3, the ground strength that is the strength of the ground on which the building 4 is built, and the like.

First, the elevator operation control device 2a calculates the approximate epicenter distance L1 (km) (approximate value of the distance from the earthquake occurrence point), which is an approximate value of the distance between the building 4 and the epicenter, by the equation (8). Approximate calculation is performed using Expression 223. The approximate epicenter distance calculation formula 223 shown in Expression (8) does not include the square calculation and the square root calculation, but includes only four arithmetic operations and condition determination. This is based on the assumption that the first report of the Earthquake Early Warning has not yet been transmitted because the depth value of the epicenter is unknown.
L1 = max (| Λ−λ | × 111 cos φ (km / degree), | Φ−φ | × 111 (km / degree)) (8)
The calculation of equation (8) calculates an approximate value of the distance between the building 4 and the epicenter by substituting a component having a larger value among the distance components in the longitude direction or the latitude direction without calculating the true epicenter distance. To do.

If the depth D (km) of the epicenter can be received, the approximate epicenter distance L2 (km) (approximate value of the distance from the earthquake occurrence point) is approximately calculated by the equation (9).
In this case, instead of the approximate epicenter distance, Equation (9), which is the approximate epicenter distance calculation formula, is stored in the storage unit 22a.
L2 = max (| Λ−λ | × 111 cos φ (km / degree), | Φ−φ | × 111 (km /
Degrees), D) ... (9)
In addition, the approximate calculation method of Formula (8) and Formula (9) has practically sufficient accuracy in middle latitude regions and low latitude regions such as Japan.

Next, the elevator operation control device 2a determines the value of L1 or L2 calculated using the equation (8) or the equation (9), the number of floors of the building 4 stored in the storage unit 22a, and the elevator 3 The predicted maximum seismic intensity in the building 4 is calculated using the elevator information 224 which is information on the journey and the ground strength.
Specifically, the predicted maximum seismic intensity calculation formula (not shown) for obtaining the predicted maximum seismic intensity using the approximate epicenter distance or approximate epicenter distance and the M value as variables is stored in the storage unit 22a in advance. In this predicted maximum seismic intensity calculation formula, the number of floors of the building 4 or the numerical value of the lifting / lowering stroke of the elevator 3, the ground strength at the place where the building 4 is built, and the like are added as variables. That is, the predicted maximum seismic intensity calculation formula is defined so that the predicted maximum seismic intensity is calculated larger as the number of floors of the building 4 or the elevator 3 is increased or decreased, and the ground strength is decreased.
The elevator operation control device 2a compares the predicted maximum seismic intensity value with a predetermined seismic intensity threshold value, and determines whether the calculated predicted maximum seismic intensity value is equal to or greater than the seismic intensity threshold value. It is determined whether or not the operation is necessary.
Further, if the degree of susceptibility to the influence of the long-period earthquake in the area where the building 4 is built is known, the necessity of the long-period control operation is determined in consideration of the data.

Next, the operation of the elevator operation control device 2a in the second embodiment will be described along FIG. 6 with reference to FIG.
FIG. 6 is a flowchart showing the flow of the elevator operation control method according to the second embodiment. In FIG. 6, the same processes as those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted or simplified.
First, the receiving unit 23 receives the earthquake early warning (S1), and passes the received emergency earthquake early warning to the processing unit 21, whereby the processing unit 21 acquires the M value and the epicenter position information (earthquake occurrence position information). (S101).
Next, the processing unit 21 acquires the building position information 221 from the storage unit 22a (S102). Then, the processing unit 21 calculates the approximate epicenter distance by substituting the epicenter position information and the building position information 221 into the approximate epicenter distance calculation formula 223 shown in Expression (8) (S103).
.

Further, the processing unit 21 acquires the elevator information 224 from the storage unit 22a (S104). Then, the processing unit 21 calculates the predicted maximum seismic intensity in the building 4 in which the elevator operation control device 2a is installed based on the approximate epicenter distance calculated in step S103 and the elevator information 224 acquired in step S104 (S105). ). The expected maximum seismic intensity is calculated by the method described above.
Next, the processing unit 21 determines whether or not the predicted maximum seismic intensity calculated in step S105 is equal to or greater than a preset seismic intensity threshold value (S106).
If the predicted maximum seismic intensity is equal to or greater than the seismic intensity threshold (S106 → No), the current seismic control operation is not performed (not implemented: S10).
When the predicted maximum seismic intensity is equal to or greater than the seismic intensity threshold (S106 → Yes), the current seismic control operation is performed (S12).

Note that the processing in FIG. 6 may be the following processing.
First, in step S <b> 101, the processing unit 21 acquires the depth of the epicenter included in the earthquake early warning from the receiving unit 23 simultaneously with the epicenter position information and the M value.
In step S103, the processing unit 21 calculates the approximate epicenter distance by substituting the epicenter position information, the building position information 221 and the depth of the epicenter into Expression (9).
In step S105, the predicted maximum seismic intensity is calculated using the approximate epicenter distance and the elevator information 224.

According to the second embodiment, the distance between the epicenter or the epicenter and the building 4 can be calculated without using a heavy calculation formula such as square root calculation.
Furthermore, since the number of conditional branch processes is small compared to the first embodiment, the process can be simplified.

  Note that another seismic control device based on the detection of the arrival of a P wave (above a preset threshold value) at the position of the building 4 at the building 4 is the elevator operation control device 2 (see FIG. 1) or the elevator operation control device 2a (see FIG. 5) of the second embodiment, the P-wave seismic control operation control and the elevator operation control device 2 or the elevator operation control device 2a are independent of each other. Execute. Even when it is determined that the control operation is not performed in the seismic control operation conditional expression of the present embodiment, the execution of the seismic control operation control based on the detection of the P wave is not hindered. Conversely, even after it is determined that the control operation is not performed in the seismic control operation control based on the P wave, the control operation is performed if it is determined that the control operation is performed according to the seismic control operation condition formula of this embodiment. To do.

(effect)
According to the first embodiment and the second embodiment shown in FIGS. 1 and 5, it is possible to perform the earthquake control operation of the elevator 3 when an earthquake occurs without using the predicted arrival time of the emergency earthquake warning. . In particular, the earthquake control operation of the elevator 3 can be performed regardless of the expected arrival time of the S wave.
In addition, the elevator operation control devices 2 and 2a can perform simple four arithmetic operations, absolute values, and condition determination to determine whether or not the earthquake control operation is necessary, and the processing time is shortened. Therefore, the earthquake control operation of the elevator 3 can be started earlier, and the first embodiment or the second embodiment can be applied even in an area closer to the epicenter and where the seismic wave reaches earlier. That is, the elevator operation control systems 1 and 1a can cover an area that is close to the epicenter and in which serious damage is a concern.
Furthermore, as described above, since simple four arithmetic operations, absolute values, and condition determination are executed, the configuration of the elevator operation control devices 2 and 2a can be simplified, and the cost can be reduced.
Also. A function corresponding to the earthquake early warning according to the first embodiment or the second embodiment can be easily added to the existing control device of the elevator 3.

  Furthermore, according to the second embodiment, the distance between the epicenter or the epicenter and the building 4 can be calculated (an approximate value of the distance can be calculated) without using a heavy calculation formula such as square root calculation. Furthermore, since the number of conditional branch processes is small compared to the first embodiment, the process can be simplified.
