Abstract

PROBLEM TO BE SOLVED: To prevent deterioration in operation efficiency and perform an appropriate operation for emergency after accurately checking vibrations of long articles (5) such as ropes and cables.SOLUTION: In the case of determining that a building shake occurs on the basis of external information used for predicting occurrence of a building shake, a single not-in-service elevator among a plurality of elevators is moved to a resonance story and, if a predetermined shake amount of a long article is detected, the elevator is put under the operation for emergency. If determined that the building shake abates, the elevator is shifted under a normal operation from the operation for emergency, and all elevators other than the not-in-service elevator is put under a normal operation continuously until the predetermined shake amount of the long article is detected by the single not-in-service elevator that has been moved to the resonance story.

Description

  In the present invention, when an elevator rope or cable (hereinafter referred to as a long object) swings in resonance with the vibration of the building, the swing of the long object is detected at an early stage, and The present invention relates to an elevator control system and an elevator control method that can restore the operation of an elevator to normal operation at an early stage when vibrations converge.

  In general, even if the acceleration of the surface of a long-period earthquake is about several gal, if the period of the earthquake and the natural period of a building (such as a high-rise building) are close, the building will resonate and the building shakes for several minutes. This occurs continuously. In addition, buildings sway slowly in the natural period due to not only long-period earthquakes but also strong winds due to the approach and passage of typhoons, resulting in building sway over a long period of time.

  In addition, long elevators with high heads installed in buildings are easily affected by slight building shaking, so depending on the position of the elevator car, the long objects may resonate with the building shaking. End up. Therefore, when a long object shakes, contact with or catching on equipment in the hoistway occurs, causing damage to the elevator.

  In order to prevent damage in the event of such building shaking, the amount of shake of the long object is directly detected by the photoelectric sensor installed in the hoistway, and based on the detected amount of shake of the long object Thus, there is a technique for performing an elevator operation (see, for example, Patent Document 1).

  In addition, by the earthquake early warnings delivered by the Japan Meteorological Agency, elevator operation such as moving the car to a floor (hereinafter referred to as a non-resonant floor) that is not affected by shaking of the building before a long-period earthquake arrives. By doing so, long objects are prevented from shaking as much as possible. There is a technique for returning the operation of the elevator from the control operation to the normal operation when it is confirmed by the pendulum sensor installed in the machine room in the upper part of the building that the shaking of the building has converged (see, for example, Patent Document 2).

  In addition, the vibration sensor installed in the upper part of the hoistway or the upper part of the building calculates the shake amount of the long object every time a predetermined time elapses. Move the car to the floor or the nearest floor and stop the elevator operation. Furthermore, the magnitude of the shake amount is divided into three stages: “Small”, “Medium” and “Large”. There is a technique for continuously controlling the elevator at each stage, such as stopping the operation when the vehicle is “large” (see, for example, Patent Document 3).

Japanese Utility Model Publication No. 60-003764 JP 2007-153520 A JP 2008-230771 A

However, the prior art has the following problems.
In the prior art described in Patent Document 1, since the shake amount of the long object is directly detected, the shake amount of the long object can be detected with high accuracy. However, the amount of shaking of the building that indicates how much the building itself is shaking cannot be detected.

  For this reason, even when the building shakes, the normal operation of the elevator is continued if the amount of shake of the long object is not detected. Therefore, in order to more reliably detect the amount of swing of a long object, it is necessary to move the car in advance to a floor (equivalent to a resonance floor) where the long object easily swings in a standby state where there are no passengers in the car. However, there was a problem that the operation efficiency was lowered.

  In the prior art described in Patent Document 2, the amount of shaking of the building itself is directly detected by a pendulum sensor. However, since the shake amount of the long object is not directly detected, it cannot be accurately confirmed whether or not the shake of the long object has occurred. Therefore, for example, even when there is no actual swing of a long object, there is a possibility that the car may be moved to a non-resonant floor and it is difficult to perform an appropriate control operation. .

  Furthermore, in the prior art described in Patent Document 3, a highly accurate vibration sensor is required in order to directly detect the amount of shaking of the building itself using the vibration sensor. Therefore, there is a problem that it is very expensive and requires great care in handling. Furthermore, in a high-rise building where the height of the building exceeds 300 m, it is difficult to accurately detect the amount of shaking of the building, and thus this conventional technique cannot be applied.

  The present invention has been made in order to solve the above-mentioned problems, and it is possible to perform appropriate control operation after suppressing a decrease in operation efficiency and accurately confirming a swing of a long object. It is an object to obtain an elevator control system and an elevator control method that can be used.

  An elevator control system according to the present invention includes a plurality of elevator control devices that individually control a plurality of elevators, and a group management device that performs group management control of the plurality of elevators by communicating with each of the plurality of elevator control devices. , Acquire external information that affects the shaking of a building with multiple elevators, determine whether there is a risk that the building will shake more than a predetermined value based on the acquired external information, and shake An elevator control system comprising a monitoring device for notifying the group management device of the occurrence prediction information of the building if the building shaking condition is satisfied. In order to detect the amount of shake of a long object passing through the road, there is a long object shake detection device installed on the resonance floor in each hoistway. When the group management device receives the shake occurrence prediction information from the monitoring device, the group management device selects one non-service elevator among the plurality of elevators as the shake measurement elevator, and selects the selected shake measurement Switch the operation mode of the elevator from normal operation to control operation, move the elevator for shake amount measurement to the resonance floor, and keep the elevators other than the elevator for shake amount measurement to continue normal operation. The elevator control device that controls each and controls the shake amount measurement elevator switches the operation mode from normal operation to control operation based on the control by the group management device, and moves the shake amount measurement elevator to the resonance floor. After that, the amount of shake of the long object detected by the long object shake detection device installed on the resonance floor is monitored for a certain period of time, When the swing amount of the scale exceeds the preset allowable swing amount, the group management device is notified as shake detection information, and when the swing amount of the long object does not exceed the allowable swing amount, the operation mode When the control device receives the shake detection information from the elevator control device corresponding to the shake amount measurement elevator, the group management device moves the shake amount measurement elevator to the non-resonant floor. Each of the plurality of elevator control devices is controlled such that an elevator other than the shake amount measuring elevator is switched to the control operation and moved to the non-resonant floor after the normal operation service is completed.

  The elevator control method according to the present invention includes a plurality of elevator control devices that individually control a plurality of elevators, and group management that performs group management control of the plurality of elevators by communicating with each of the plurality of elevator control devices. Acquire external information that affects the shaking of the device and the building where multiple elevators are installed, and based on the acquired external information, determine whether there is a risk that the building will shake more than a predetermined value. In the case of an elevator control method applied to an elevator control system provided with a monitoring device for notifying the group management device of the occurrence of shaking prediction when it is determined that there is a risk of shaking. A plurality of elevators are installed on the resonance floor in each hoistway in order to detect the shake amount of a long object passing through the hoistway. When there is a long object shake detection device and the group management device receives shake occurrence prediction information from the monitoring device, one non-service elevator of the plurality of elevators is used as a shake amount measurement elevator. Switch the operation mode of the selected runout measurement elevator from normal operation to control operation, move the runout measurement elevator to the resonance floor, and continue the normal operation of elevators other than the runout measurement elevator As described above, in the shake amount measurement processing step for controlling each of the plurality of elevator control devices and the elevator control device corresponding to the shake amount measurement elevator, the operation mode is set based on the shake amount measurement processing step by the group management device. After switching from normal operation to control operation, moving the shake measurement elevator to the resonance floor, The amount of shake of the long object detected by the long object shake detection device installed on the tremor floor is monitored for a certain period of time, and if the amount of shake of the long object exceeds the preset allowable shake amount, When the group management device is notified as shake detection information, and the shake amount of the long object does not exceed the allowable shake amount, the shake amount judgment processing step for returning the operation mode from the control operation to the normal operation, and the group management device When the shake detection information is received from the elevator control device corresponding to the shake amount measurement elevator, the shake amount measurement elevator is moved to the non-resonant floor, and the elevator other than the shake amount measurement elevator is in a normal operation service. A post-runout detection processing step for controlling each of the plurality of elevator control devices so that the control operation is switched to the non-resonant floor after the operation is completed. It is.

  According to the present invention, when it is determined that there is a risk of building shaking exceeding a predetermined value on the basis of external information, only one elevator that is not in service is switched from normal operation to control operation to resonate. When the amount of vibration being monitored exceeds the allowable amount of vibration, switch from normal operation to control operation for one elevator that is not in service, and control operation Elevator control system that can perform appropriate control operation after accurately checking the run-out of long objects while suppressing the decrease in operation efficiency by retreating all elevators inside to the non-resonant floor And an elevator control method can be obtained.

  Hereinafter, preferred embodiments of an elevator control system and an elevator control method of the present invention will be described with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram showing an overall configuration of one elevator among a plurality of elevators provided in the elevator control system according to Embodiment 1 of the present invention. The elevator control system according to the first embodiment includes a plurality of elevators, a group management device (not shown), and a monitoring device (not shown). Further, as shown in FIG. 1, each of the elevators of the plurality of elevators includes an elevator hoistway 1, a car 2, a counterweight 3, a deflector 4, a main rope 5, a hoisting machine 6, and a landing 7. (1), 7 (2), 7 (3), an elevator control device 100, a first photoelectric sensor 200, and a second photoelectric sensor 300 are provided. Although not shown, each elevator has a long object shake detection device that detects the shake amount of a long object based on the detection results of the first photoelectric sensor 200 and the second photoelectric sensor 300. .

  A car 2 and a counterweight 3 that move up and down in the elevator hoistway 1 are suspended from a main rope 5 via a deflecting wheel 4. By rotating the hoisting machine 6 around which the main rope 5 is wound, the car 2 and the counterweight 3 are moved up and down like a fishing bottle. Here, among the long objects that swing in resonance with the shaking of the building, the case where the main rope 5 swings will be described with specific examples, and the other long objects are the same as the main rope 5. The description is omitted.

  As an example of the landing 7, landings 7 (1) to 7 (3) shown in FIG. 1 are landings on each floor from the first floor to the third floor. The elevator control device 100 controls the rotation of the hoisting machine 6 so that the car 2 moves up and down in the elevator hoistway 1 based on a control command from the group management device. The long object shake detection device directly detects the shake amount of a long object (here, the main rope 5) using a position sensor. In FIG. 1, a first photoelectric sensor 200 and a second photoelectric sensor 300 are shown as specific examples of the position sensor.

  Each of the first photoelectric sensor 200 and the second photoelectric sensor 300 includes a light projector that emits light and a light receiver that receives light. The first photoelectric sensor 200 is installed such that the projector and the light receiver are paired in the front-rear direction of the elevator hoistway 1. Further, the second photoelectric sensor 300 is installed such that the projector and the light receiver are paired in the left-right direction of the elevator hoistway 1. Therefore, the long object shake detection device can directly detect the shake amount of the long object by detecting the operation signals of the first photoelectric sensor 200 and the second photoelectric sensor 300.

  Specifically, the first photoelectric sensor 200 and the second photoelectric sensor 300 are installed in an elevator hoistway 1 as shown in FIG. Installed on the resonance floor corresponding to the floor. FIG. 2 is a plan view of the elevator hoistway 1 shown in FIG. 1 in the first embodiment of the present invention. Each of the first photoelectric sensor 200 and the second photoelectric sensor 300 is composed of a plurality of photoelectric sensors. Here, in order to specifically illustrate and explain, the main rope 5 is composed of two photoelectric sensors. Assume the case of detecting run-out.

  Further, as shown in FIG. 2, the photoelectric sensor 201 separates a line connecting the projector 201 (P) and the light receiver 201 (R) positioned in the front-rear direction from the main rope 5 by a first predetermined distance, and It is installed in the hoistway 1. Further, as shown in FIG. 2, the photoelectric sensor 202 separates a line segment connecting the projector 202 (P) and the light receiver 202 (R) positioned in the front-rear direction from the main rope 5 by a second predetermined distance, and It is installed in the hoistway 1. The second predetermined distance is longer than the first predetermined distance.

  Further, when the main rope 5 swings left and right and passes through the detection range of the photoelectric sensor 201, the long object shake detection device directly determines the swing amount of the main rope 5 based on the level 1 operation signal output from the photoelectric sensor 201. To detect. Further, the long object shake detection device determines that the shake amount of the main rope 5 is level 1, and outputs the shake level information (corresponding to shake detection information) as level 1 to the elevator control device 100.

  Further, when the main rope 5 is gradually shaken from side to side and passes through the detection range of the photoelectric sensor 202, the long-body shake detection device detects the main rope 5 based on the level 2 operation signal output from the photoelectric sensor 202. The shake amount of 5 is directly detected. Further, the long object shake detection device determines that the shake amount of the main rope 5 is level 2, and outputs the shake level information to the elevator control device 100 as level 2. As described above, the long object shake detection device can determine the shake amount of the main rope 5 in the left-right direction for each level based on the operation signal of the first photoelectric sensor 200.

  In addition, what is necessary is just to prescribe | regulate the 1st predetermined distance and the 2nd predetermined distance according to the deflection amount of the main rope 5 determined for every level. For example, the first predetermined distance is preferably about 50% of the distance from the main rope 5 to a hoistway device (not shown) located in the elevator hoistway 1, and the second predetermined distance is from the main rope 5. About 90% of the distance to the hoistway equipment is preferable.

  Similarly, the second photoelectric sensor 300 is used to detect the shake of the main rope 5 in the front-rear direction, and includes a photoelectric sensor 301 including a projector 301 (P) and a light receiver 301 (R), and a projector 302 ( P) and a photoelectric sensor 302 composed of a light receiver 302 (R) and two photoelectric sensors.

  In addition, as shown in FIG. 2, the photoelectric sensor 301 separates a line segment connecting the light projector 301 (P) and the light receiver 301 (R) positioned in the left-right direction from the main rope 5 by a first predetermined distance, and It is installed in the hoistway 1. Further, as shown in FIG. 2, the photoelectric sensor 302 separates a line segment connecting the light projector 302 (P) and the light receiver 302 (R) positioned in the left-right direction from the main rope 5 by a second predetermined distance, and It is installed in the hoistway 1. The second predetermined distance is longer than the first predetermined distance.

  In addition, the long object shake detection device can determine the shake amount in the front-rear direction of the main rope 5 for each level based on the operation signal of the second photoelectric sensor 300 by performing the same operation as described above. .

  In addition, although the 1st photoelectric sensor 200 and the 2nd photoelectric sensor 300 are installed in the hoistway 1 of an elevator, both do not necessarily need to be installed and only one of them may be installed. Further, in the case where the determination for each level of the shake amount of the main rope 5 performed by the elevator long shake detection device in FIG. 1 is made more detailed, there are a plurality of other photoelectric sensors other than the first photoelectric sensor 200 and the second photoelectric sensor. It may be installed.

  The group management device outputs a control command to the elevator control device 100 so that the elevator performs a normal operation or a control operation based on shake occurrence prediction information input from a monitoring device described later. Further, the group management device outputs a similar control command not only to the elevator control device 100 but also to the elevator control devices provided in each of the plurality of elevators. Manage each operation.

  The monitoring device is installed in, for example, a building disaster prevention center, and the monitoring device includes external information for predicting the occurrence of building shaking in advance (in other words, it corresponds to external information that affects building shaking). , Hereinafter referred to simply as external information). In addition, the monitoring device predicts the occurrence of building shaking by determining whether or not there is a possibility that the building where the elevator is installed will shake more than a predetermined value based on this external information. It is determined whether the building shaking condition is satisfied. Furthermore, the monitoring device outputs the shake occurrence prediction information to the group management device depending on whether the building shake condition is satisfied. The external information mentioned here includes, for example, wind speed measured by an anemometer (not shown) installed in a building, or weather data such as emergency earthquake warning and strong wind warning distributed from the Japan Meteorological Agency.

  Next, FIG. 3 shows the details of the functional configuration of an elevator control system including an elevator control device and a long-body shake detection device, a group management device, and a monitoring device provided in each of a plurality of elevators. Will be described with reference to FIG. FIG. 3 is a block diagram showing a functional configuration of the elevator control system according to Embodiment 1 of the present invention.

  FIG. 3 shows an elevator control device 100 (referred to as elevator control devices 100A and 100B) provided in each of two elevators (referred to herein as elevators A and B) among a plurality of elevators. First photoelectric sensor 200 (referred to as first photoelectric sensor 200A, 200B), second photoelectric sensor 300 (referred to as second photoelectric sensor 300A, 300B), and long object shake detection device (long object shake detection device 400A) , 400B).

  3 also shows the group management device 500, the monitoring device 600, and the external information 700. Since the functions and configurations of the parts of the elevator A and the elevator B are the same, the elevator A will be described and the description of the elevator B will be omitted.

  The elevator control device 100A includes an operation control unit 101A and a car position detection unit 102A. The operation control unit 101A performs operation control of the elevator based on the control command input from the group management device 500. Further, the car position detection unit 102A detects car position information indicating where the car 2 of the elevator A is located in the elevator hoistway 1 and outputs it to the operation control unit 101A.

  The first photoelectric sensor 200A includes a photoelectric sensor 201A and a photoelectric sensor 202A, similar to the first photoelectric sensor 200 described above. In addition, the second photoelectric sensor 300A includes a photoelectric sensor 301A and a photoelectric sensor 302A, similarly to the second photoelectric sensor 300 described above.

  The long object shake detection device 400A includes a level 1 detection unit 401A and a level 2 detection unit 402A. Further, the level 1 detection unit 401A determines that the swing amount of the main rope 5 is level 1 when a level 1 operation signal is input from the photoelectric sensor 201A or the photoelectric sensor 301A. Further, the level 2 detection unit 402A determines that the swing amount of the main rope 5 is level 2 when a level 2 operation signal is input from the photoelectric sensor 202A or the photoelectric sensor 302A. Further, when the swing amount of the main rope 5 is level 1 with respect to the operation control unit 101A, the level 1 detection unit 401A outputs the swing level information (corresponding to the shake detection information), and the swing of the main rope 5 is When the amount is level 2, the level 2 detector 402A outputs shake level information (corresponding to shake detection information).

  The group management device 500 includes a control operation control unit 501 and a resonance floor allocation unit 502. The control operation control unit 501 outputs a control command to the operation control unit 101A based on the operation information input from the operation control unit 101A and the shake occurrence prediction information input from the monitoring device 600. That is, the control operation control unit 501 outputs a control command to the operation control unit 101A so as to make a transition to control operation, continue normal operation, or return to normal operation due to convergence of building shake. Here, the operation information input from the operation control unit 101A is detected by the input of the car position information of the elevator A input from the car position detection unit 102A and the long object shake detection device 400A. This is the swing level information of the main rope 5.

  Similarly, the control operation control unit 501 issues a control command to the operation control unit of each elevator control device of a plurality of elevators other than the elevator A by performing the same operation on the operation control unit 101A. Output.

  Further, the resonance floor allocating unit 502 selects one elevator as a shake amount measuring elevator among the non-service elevators in the bank, and serves as an operation control unit of the elevator control device in the selected shake amount measuring elevator. On the other hand, a control command is output to move to the resonance floor and wait.

  The monitoring device 600 includes an elevator control unit 601. Based on the input external information 700, the elevator control unit 601 determines whether or not a building shaking condition, which is a condition for building shaking, is satisfied, and the control operation control unit 501 uses the determination result as shaking generation prediction information. Output to. FIG. 3 shows, as an example of the external information 700, wind speed information 701 measured by an anemometer installed in a building, an emergency earthquake warning 702 distributed from the Japan Meteorological Agency, and a strong wind warning 703.

  Next, the operation procedure of the elevator control system in FIG. 3 will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing an operation procedure of the elevator control system according to Embodiment 1 of the present invention. Here, for the sake of specific illustration and explanation, elevator B in FIG. 3 is an elevator in service, elevator A is an elevator in non-service, and normal operation of the elevator is performed. Assuming that

  In addition, the control operation performed when the group management device 500 predicts the occurrence of a building shake based on the shake occurrence prediction information input from the step monitoring device 600 includes a first control operation and a second control operation. Here, the elevator control system according to the first embodiment has the following technical features.

(Feature 1) When the monitoring device 600 determines that the building shaking condition is satisfied, the group management device 500 selects the elevator A that is in non-service among the elevators that perform normal operation as the first control operation, A control command is output to the elevator control device 100A so that the elevator A is on standby at the resonance floor, and the result of monitoring the shake amount by the long object detection device 400A of the elevator A on standby at the resonance floor is a long object. When the predetermined shake amount is detected (that is, when the detected shake amount exceeds the allowable shake amount), a control command is further output so that the elevator A waits from the resonance floor to the non-resonance floor.
(Feature 2) The group management device 500 outputs a control command so that an elevator other than the elevator A (here, the elevator B) performs the second control operation, and the monitoring device determines that the building shaking condition is not satisfied In addition, a control command is output so as to return from the control operation to the normal operation.

  The specific operation content of the second control operation is not limited to the example of the flowchart shown in FIG. 4, and when the monitoring device 600 determines that the building shaking condition is not satisfied, the elevator A and the elevator B are normally Any driving content may be used as long as it returns to driving.

  In the flowchart in FIG. 4, in step S <b> 401, the elevator control unit 601 of the monitoring device 600 determines whether or not the building shaking condition is satisfied based on the input external information 700.

  It should be noted that the building shaking condition here may be defined in advance by the user based on the contents of the external information 700. That is, for example, when the external information 700 is the wind speed information 701, if the wind speed in the input wind speed information is equal to or greater than a predetermined wind speed value (for example, a measured wind speed of 15 m or more), the elevator control unit 601 may Is determined to have been established. Further, when the external information 700 is the earthquake early warning 702, if the input seismic intensity information is a predetermined seismic intensity value or more (for example, seismic intensity 4 or more, etc.), the elevator control unit 601 satisfies the building shaking condition. Is determined. When the external information 700 is the strong wind warning 703, if the strong wind warning is issued, the elevator control unit 601 determines that the building shaking condition is satisfied.

  In step S401, if the elevator control unit 601 determines that the building swing condition is not satisfied (that is, No), in step S402, the control operation control unit 501 of the group management device 500 provides the vibration generation prediction information as Outputs information that the building does not shake.

  In step S402, the control operation control unit 501 continues normal operation to the operation control units 101A and 101B of the elevator control devices 100A and 100B based on the information input from the elevator control unit 601. A control command is output to. Further, in the elevator control system, after the elevator control unit 601 and the control operation control unit 501 execute the process of step S402, the process returns to step S401 again and executes a series of processes of the flowchart. In this case, if the elevator A that is not in service is arranged on the floor where the hall call is likely to occur, the operation efficiency becomes more efficient.

  On the other hand, in step S401, if the elevator control unit 601 determines that the building shaking condition is satisfied (that is, Yes), in step S403, the building shaking occurs in the control operation control unit 501 as the shaking occurrence prediction information. Outputs information to that effect. The elevator control unit 601 outputs the shake occurrence prediction information only when it is determined that the building shake condition is satisfied, and does not output the shake occurrence prediction information when it is determined that the building shake condition is not satisfied. It is also possible.

  In step S403, the control operation control unit 501 instructs the resonance floor allocation unit 502 to perform the following operation based on the information input from the elevator control unit 601. That is, the resonance floor assignment unit 502 selects, as the first control operation, one elevator (in this case, elevator A) from non-service elevators, moves to the resonance floor, and waits for operation control. A control command is output to the unit 101A. If there is no non-service elevator, the first elevator that has become non-service from the service is moved to the resonance floor and placed on standby.

  Next, in step S404, the control operation control unit 501 determines that the operation control unit 101A of the elevator A waiting on the resonance floor has a predetermined swing amount of the long object, and the swing amount of the main rope 5 is level 1. It is determined whether or not the shake level information (hereinafter, simply referred to as level 1) indicating is detected.

  In step S404, if the control operation control unit 501 determines that the operation control unit 101A does not detect level 1 (that is, No), the elevator control unit 601 determines that the building is based on the external information 700 in step S405. It is determined whether or not the determination that the shaking condition is satisfied is continued.

  In step S405, the control operation control unit 501 returns to step 402 when the elevator control unit 601 determines that the building swing condition has not been satisfied (that is, No), and returns to the operation control unit 101A. The control command is output so as to return to the normal operation from the standby on the non-resonant floor.

  That is, for example, when the external information 700 is the wind speed information 701, if the wind speed in the input wind speed information is less than a predetermined wind speed value (for example, less than 15 m of the measured wind speed), the building shake converges, so the elevator control The unit 601 determines that the building shaking condition is not satisfied. Further, when the external information 700 is the emergency earthquake warning 702, the elevator controller 601 ensures that the building shake converges after securing sufficient time from the estimated earthquake arrival time (for example, 10 minutes later). It is determined that the shaking condition is not satisfied. When the external information 700 is the strong wind warning 703, if the strong wind warning is canceled, the building shake converges, so the elevator control unit 601 determines that the building shake condition is not satisfied. In such cases, the control operation control unit 501 determines that the elevator control unit 601 does not continue to determine whether the building shaking condition is satisfied (the building shaking condition is not established).

  On the other hand, in step S405, the control operation control unit 501 returns to step 403 when the elevator control unit 601 determines that the building shaking condition is established (that is, Yes), and returns to step 403. A control command is output to the control unit 101A so as to continue standby on the non-resonant floor. That is, the processing in steps S403 and S404 is repeated for a certain period of time when the determination of establishment of the building shaking condition is continued.

  On the other hand, if the control operation control unit 501 determines in step S404 that the operation control unit 101A has detected level 1 (that is, Yes), in step S406, the control operation control unit 501 is on standby at the resonance floor with respect to the operation control unit 101A. A control command is output so that the elevator A travels to a non-resonant floor and waits.

  Next, in step S407, the control operation control unit 501 operates as an operation control unit for an elevator (in this case, elevator B) that continues normal operation other than the elevator A that is placed on the non-resonant floor as the second control operation. A control command is output to 101B so as to prohibit new hall call registration. That is, the operation control unit 101B does not respond to a new call from a user at the landing, and prohibits the user at the landing from using the elevator B.

  In step S407, the control operation control unit 501 continues the service for the call in the already registered car to the operation control unit 101B, and the user in the car continues the elevator B. Output control commands for use. On the other hand, a registered hall call can be canceled.

  The operation of the control operation control unit 501 in step S407 may be performed after it is determined Yes in step S401, or may be performed after it is determined Yes in step S404. .

  Next, in step S408, the control operation control unit 501 determines whether or not the elevator B has responded to all registered car calls and has completed the service. If the control operation control unit 501 determines in step S408 that the elevator B has not completed the service (that is, No), the process returns to step S407.

  On the other hand, if the control operation control unit 501 determines in step 408 that the elevator B has completed the service (that is, Yes), the operation control unit 101B of the elevator B that has completed the service in step S409 A control command is output so that the vehicle travels to the resonance floor and waits, and a series of operations ends.

  In addition, the control operation control unit 501 performs the normal operation from the control operation if the building shake converges after the elevator A and the elevator B are shifted to the control operation such as the first control operation and the second control operation according to the flowchart in FIG. Return to driving. That is, the control operation control unit 501 returns to the normal operation from the control operation when the elevator control unit 601 determines that the building shake condition is not established by performing the same operation as in step S405. Let

  As described above, according to the first embodiment of the present invention, when it is determined that a building shake will occur based on external information for predicting the occurrence of a building shake in advance, out of the elevators that are not in service. If one of the elevators is moved to the resonance floor and a predetermined swing amount of a long object is detected, the elevator will be controlled, and if it is determined that the building shake will converge, the elevator will Return to operation.

  Further, except for one elevator that is not in service, normal operation is continued until a predetermined amount of swing of a long object is detected by one elevator that has moved to the resonance floor and is not in service. When a predetermined swing amount of the scale is detected, after executing the registered call registration service, the control mode is switched to a non-resonant floor. Thereby, while suppressing the fall of operation efficiency, after confirming the shake of a long thing correctly, an appropriate control operation can be performed.

  Furthermore, since it can be determined that the building shake converges based on external information, the building shake is caused by waiting the elevator for a predetermined time on the floor where long objects are likely to swing when returning from control operation to normal operation. Therefore, the confirmation operation for confirming the convergence is not required, and it is possible to return to the normal operation more efficiently.
