Description

  The present invention relates to an elevator control device.

  Conventionally, there is known an elevator monitoring system in which a monitoring center that collectively monitors elevators installed in a plurality of customer buildings and an information providing server that provides disaster prediction information are connected via a communication network. (For example, refer to Patent Document 1). The monitoring center provided in the elevator monitoring system described in Patent Document 1 specifies a customer building that is predicted to be flooded based on disaster prediction information and customer location map data provided from the information providing server, The floor of the customer building corresponding to the flooded height is specified based on the information indicating the height position of each floor related to the customer building and the disaster prediction information provided from the information providing server.

  In addition, the elevator control system provided in this elevator monitoring system detects inundation installed in the customer building when it receives information from the monitoring center indicating that inundation damage will occur and information indicating the floor corresponding to the inundation height. When inundation is detected by the vessel, the elevator operation mode is switched from the normal operation mode to the disaster operation mode. In this disaster operation mode, the elevator controller moves the elevator car to a floor above the floor corresponding to the flooded height, and moves the floor below the floor corresponding to the flooded height. In addition to being set as a non-stop floor, the floor above the floor corresponding to the flooded height is set as a stop floor, and the car is allowed to move only between the floors set as stop floors.

JP 2004-203562 A JP 2007-126261 A Japanese Patent No. 4601280

  Thus, for example, a conventional elevator control device as shown in Patent Document 1, for example, corresponds to the flooding height by shifting to the disaster operation mode after the flooding is detected by the flooding detector. It is moved to a floor above the floor.

  However, in this case, in the case of a tsunami, the water level is suddenly increased, so that if the car is moved upward after detecting inundation, the car may be inundated in time. In the case of a tsunami, for the same reason, it is assumed that the time that the elevator can be operated after detecting inundation is extremely short. It cannot be evacuated.

  The present invention has been made to solve such a problem. When a tsunami is expected to reach the building where the elevator is installed, the elevator is as far as possible to evacuate people in the building. It is possible to obtain an elevator control device that can utilize the above.

  In the elevator control device according to the present invention, based on the tsunami information receiving means for receiving tsunami information and the tsunami information received by the tsunami information receiving means, the building where the elevator is installed is the target area of the tsunami information. Tsunami area determination means for determining whether or not included, tsunami arrival time storage means for storing a tsunami arrival time extracted from the tsunami information when the building is included in the target area of the tsunami information, and When a building is included in the target area of the tsunami information, tsunami height storage means for storing the height of the tsunami extracted from the tsunami information, and higher than the tsunami height stored in the tsunami height storage means The floor determination means for determining the floor of the building to determine the evacuation floor, and the rescueable time is obtained based on the tsunami arrival time stored in the tsunami arrival time storage means. Rescue time determination means for determining whether or not time has elapsed, and before the elapse of the rescue time, service floor management means for enabling an upward hall call on a floor below the evacuation floor, It is set as the structure provided with.

  In the elevator control device according to the present invention, when a tsunami is expected to reach the building where the elevator is installed, the elevator can be used as much as possible for evacuation of people in the building. There is an effect.

Embodiment 1 FIG.
FIG. 1 to FIG. 3 explain the configuration and operation that are the premise of Embodiment 1 of the present invention. FIG. 1 is a block diagram showing the overall configuration of an elevator system including an elevator control device, FIG. FIG. 3 is a flowchart showing the operation of the elevator control device.

  In FIG. 1, an in-car destination button 1 a is installed inside a car 1 that can be raised and lowered in a hoistway of an elevator. This in-car destination button 1a is used for registering a call to a desired destination floor when operated by a user who has entered the car 1. The in-car destination button 1a includes a plurality of buttons provided corresponding to the floors that can be selected as the destination floor of the car 1.

  A landing button 2 is provided at each floor where the car 1 stops. The landing button 2 is for registering a landing call to the floor where the landing button 2 is installed by being operated by a user of the landing. The hall buttons 2 on the floors other than the top floor and the bottom floor are composed of an upward button and a downward button. Since it is only necessary to register the hall call in the downward direction on the top floor, the hall button 2 on the top floor need only have a down button, and does not need to have an up button. Conversely, since it is only necessary to register an upward hall call on the lowest floor, the hall button 2 on the lowest floor need only have an upward button, and need not have a downward button.

  The overall operation of the elevator, including registration of calls in the elevator and responses to registered calls, is controlled by the control device body 3. When the user operates the in-car destination button 1a, an operation signal including the contents of the operation is input to the control device main body 3 from the in-car destination button 1a. When the landing button 2 is operated by the user, an operation signal including the content of the operation is input from the landing button 2 to the control device main body 3.

  When the operation signal from the car destination button 1a or the landing button 2 is input, the control device main body 3 registers a call based on the content indicated by the input operation signal. Then, the operation of the car 1 is controlled to answer the call thus registered.

  The control device main body 3 includes a tsunami information receiving means 5, a building address storage means 6, a tsunami area determination means 7, a tsunami height storage means 8, a tsunami damage prediction storage means 9, a floor determination means 10, a service floor management means 11 and The operation control means 12 is provided.

  The tsunami information receiving means 5 is for receiving the tsunami information distributed from the tsunami information distribution server 4 installed outside the elevator control device. Here, the tsunami information distribution server 4 is installed outside the building where the elevator is installed. Further, here, the tsunami information distribution server 4 continues the following description on the assumption that the tsunami information distribution server 4 distributes information on tsunamis announced by the Japan Meteorological Agency.

  Information on tsunamis announced by the Japan Meteorological Agency can be broadly divided into three types: tsunami warnings and warnings, tsunami information, and tsunami forecasts. Of these pieces of information, the tsunami information distribution server 4 distributes at least tsunami information (particularly, “information regarding expected tsunami arrival time / expected tsunami height”, the same applies hereinafter). Then, the tsunami information receiving means 5 receives at least the same information.

  Among the tsunami information, “Information about predicted tsunami arrival time / expected tsunami height” includes information on expected tsunami arrival time and predicted tsunami height for each tsunami prediction area. . In other words, the tsunami information distributed from the tsunami information distribution server 4 includes an area where the tsunami is expected to arrive (tsunami forecast area), an expected tsunami arrival time in the area where the tsunami is expected to reach, and an expected time. Contains information on the height of the tsunami.

In the building address storage means 6, the address of the building (building) where the elevator is installed is stored in advance.
The tsunami area determination means 7 acquires the tsunami forecast zone included in the tsunami information received by the tsunami information reception means 5 and refers to the information stored in the building address storage means 6 so that the elevator is installed. Determine whether a tsunami is expected to reach the building location. Specifically, the tsunami area determination unit 7 arrives at the location of the tsunami when the arrival of the tsunami is predicted to the tsunami forecast area to which the location of the building belongs in the received tsunami information. Is determined to be expected.

  When the arrival of the tsunami to the location of the building where the elevator is installed is predicted, the tsunami area determination means 7 uses the tsunami information to estimate the expected tsunami height in the tsunami prediction area to which the location of the building belongs. Get it. The obtained predicted tsunami height is stored in the tsunami height storage means 8.

  The tsunami damage prediction storage means 9 stores in advance information related to tsunami inundation prediction in the area to which the building (building) where the elevator is installed belongs. The tsunami inundation prediction stored in the tsunami damage prediction storage means 9 can be created from, for example, an inundation prediction map of a tsunami hazard map published by a local government or the like.

  The floor determination unit 10 first determines whether the elevator is based on the predicted tsunami height stored in the tsunami height storage unit 8 and the tsunami inundation prediction stored in the tsunami damage prediction storage unit 9. Calculate the predicted height of the tsunami when the tsunami reaches the location of the installed building.

  Next, the floor determination means 10 determines the floor of the building (hereinafter referred to as “tsunami height equivalent floor”) corresponding to the predicted value of the height of the tsunami when the tsunami reaches the location of the building. . Here, the floor of the building corresponding to the predicted tsunami height is the highest floor among the floors whose floor height is lower than the predicted tsunami height. It is a floor. And the floor determination means 10 determines all floors above the floor one floor above the tsunami height equivalent floor thus obtained as the evacuation floor. Or you may make it determine one or more floors of the floors more than the floor one floor above a tsunami height equivalent floor as an evacuation floor.

  Here, the standard of “expected tsunami height” in the tsunami information released by the Japan Meteorological Agency is the tide level (normal tide level) when there is no tsunami. Therefore, in the above calculation, the floor determination means 10 uses the predicted tsunami height after appropriately converting the height of the tsunami into, for example, a value based on the altitude above sea level.

  The service floor management unit 11 manages the service floor of the car 1, that is, the floor on which the car 1 can operate, based on the evacuation floor determined by the floor determination unit 10. Specifically, regarding the operation of the landing button 2, only the upward hall call registration is valid on the floor below the evacuation floor, and the downward hall call registration is invalid. In addition, for the operation of the destination button 1a in the car, call registration with the floor below the evacuation floor as the destination floor is invalid, and only call registration with the evacuation floor as the destination floor is valid.

  The operation control means 12 controls the operation of the car 1 based on the determination result by the tsunami area determination means 7 and the information about the service floor (including the service direction) managed by the service floor management means 11.

  The control device body 3 configured as described above controls switching of the operation mode of the elevator that is the control target. As the operation mode, here, at least a normal operation mode in which normal operation is performed in normal times, and a disaster operation mode in which a disaster such as an earthquake or a fire or a tsunami is expected to occur is assumed. One is set. The control device body 3 controls the operation of the car 1 according to the contents set in the currently selected operation mode while switching the operation mode of the elevator.

  The flow charts of FIGS. 2 and 3 illustrate the operation of the elevator control device, particularly when the operation mode is switched from the normal operation mode to the disaster operation mode when a tsunami is expected to arrive. is there. 2 is the first half of the flow showing the operation, and FIG. 3 is the second half of the flow showing the operation, and a series of flows is formed by combining these FIGS.

  First, at the start of this flow, the elevator operation mode is the normal operation mode. In step S1, the tsunami information receiving means 5 includes information on the area where the tsunami is expected to arrive, the expected tsunami height and the expected arrival time from the tsunami information distribution server 4 (Meteorological Agency server). Get tsunami information. In the subsequent step S2, the tsunami information receiving means 5 inputs the tsunami information acquired in step S1 to the tsunami area determining means 7.

  In the subsequent step S3, the tsunami area determination means 7 acquires the address information of the building where the elevator is installed from the building address storage means 6. Then, the tsunami area determination means 7 determines whether the location of the building is a tsunami target area, that is, the arrival of a tsunami included in the tsunami information input in step S2 It is determined whether or not the area is within the expected area (tsunami forecast area).

  In this step S3, when the location of the building is not a tsunami target area, the process proceeds to (A) in FIG. This (A) corresponds to the same reference numerals in FIG. Therefore, when it reaches (A) in FIG. 2, a series of operation | movement flows are complete | finished as shown in FIG. In this case, the operation mode of the elevator remains in the normal operation mode.

  On the other hand, if the location of the building is a tsunami target area in step S3, the control device body 3 switches the elevator operation mode to the disaster operation mode, and then proceeds to step S4. After this, steps S4 to S13 are operations in the disaster operation mode. In step S4, the tsunami area determination means 7 acquires the expected tsunami height in the tsunami forecast area to which the location of the building belongs from the tsunami information. The obtained predicted tsunami height is stored in the tsunami height storage means 8.

  In the subsequent step S5, the floor determination means 10 is first based on the expected tsunami height stored in the tsunami height storage means 8 and the tsunami inundation prediction stored in the tsunami damage prediction storage means 9. Thus, a predicted value of the height of the tsunami when the tsunami reaches the location of the building where the elevator is installed is calculated. Then, the floor corresponding to the tsunami height is obtained from the predicted value of the tsunami height, and all floors above the floor one floor above the floor corresponding to the tsunami height are determined as evacuation floors.

  In the subsequent step S6, the service floor management means 11 includes the up direction button of the hall buttons 2 of the floors below the tsunami height equivalent floor (that is, the floor below the evacuation floor) and the destination button 1a in the car. The operation to the destination button corresponding to the evacuation floor is enabled (service available), and the operation to the other call registration buttons is disabled (service unavailable).

  In step S7, when the user operates the landing button 2 on any floor, in step S8, the operation control means 12 determines whether the landing button 2 operated in step S7 is valid (service available). judge. If the operated hall button 2 is invalid (service unavailable) in step S8, the process returns to step S7.

  On the other hand, when the operated hall button 2 is valid (service available), the process proceeds to (B) in FIG. This (B) corresponds to the same reference numerals in FIG. Therefore, when it reaches (B) in FIG. 2, it progresses to step S9 of FIG. In step S9, the operation control means 12 dispatches (runs) the car 1 to the floor where the hall button 2 operated in step S7 is installed.

  In subsequent step S10, when the user gets into the car 1 that has arrived and operates the in-car destination button 1a, in step S11, the operation control means 12 enables the in-car destination button 1a operated in step S10 (service available). ). If the operated car destination button 1a is invalid (service unavailable) in step S11, the process returns to step S10.

  On the other hand, if the operated car destination button 1a is valid (service available), the process proceeds to the next step S12. In step S12, the operation control means 12 causes the car 1 to travel to the floor corresponding to the car destination button 1a operated in step S10. As is clear from the above description, the destination floor of the car 1 at this time is an evacuation floor. Then, when the car 1 arrives at the evacuation floor, the user who has boarded the car 1 arrives at the evacuation floor (step S13), and the series of operation flow ends.

FIGS. 4 to 6 relate to Embodiment 1 of the present invention. FIG. 4 is a block diagram showing the overall configuration of an elevator system including an elevator control device, and FIGS. 5 and 6 are diagrams of the elevator control device. It is a flowchart which shows operation | movement.
The first embodiment of the present invention shown in these figures is applied to the building where the elevator is installed using the estimated tsunami arrival time included in the received tsunami information in addition to the above-described premise configuration. The time until the tsunami arrives is calculated, and the elevator is used to evacuate the people in the building as long as the cage of the elevator is not damaged by the tsunami.

  In this Embodiment 1, as shown in FIG. 4, in addition to the structure shown in FIG. 1 which is a premise structure, the control apparatus body 3 further includes a tsunami arrival time storage means 13 and a rescueable time determination means. 14 and rescueable time storage means 15 are provided.

  The tsunami area determination means 7, when the arrival of the tsunami to the location of the building where the elevator is installed is predicted, the estimated tsunami height in the tsunami forecast zone to which the location of the building belongs from the tsunami information In addition to the estimated time of tsunami arrival. The acquired estimated tsunami arrival time is stored in the tsunami arrival time storage means 13.

  The rescueable time determination unit 14 calculates the rescueable time in the elevator from the information stored in the tsunami arrival time storage unit 13 and the information on the evacuation floor obtained by the floor determination unit 10. Specifically, the rescueable time is calculated as follows. First, the rescueable time determination means 14 calculates the travel time required for the car 1 to travel from the lowest floor of the building to the evacuation floor (the lowest floor among them).

  Then, the rescueable time determination unit 14 obtains a time that is the calculated travel time before the estimated tsunami arrival time stored in the tsunami arrival time storage unit 13. The obtained time is the rescueable time. As can be seen from the above calculation process, the rescue time is to move the car 1 to the evacuation floor (ie, the floor that is higher than expected to reach the tsunami) before the tsunami arrives. This means a time limit for keeping the car 1 on the floor below the evacuation floor.

  The rescueable time calculated in this way is stored in the rescueable time storage means 15. Further, the rescueable time determination means 14 determines at any time whether or not the current time is before the rescueable time. Since the estimated tsunami arrival time of the tsunami information is on the coastline, when the building is inland, the rescue time was calculated based on the information stored in the building address storage means 6 The estimated tsunami arrival time may be corrected using the distance from the coastline to the building.

  The service floor management means 11 operates on the floor below the evacuation floor with respect to the operation of the landing button 2 while the rescue time determination means 14 determines that the current time is before the rescue time. Only direction hall call registration is valid, and downward direction hall call registration is invalid. In addition, for the operation of the destination button 1a in the car, call registration with the floor below the evacuation floor as the destination floor is invalid, and only call registration with the evacuation floor as the destination floor is valid.

  After the rescueable time determination unit 14 determines that the current time has passed the rescueable time, the service floor management unit 11 limits the service floor to the evacuation floor determined by the floor determination unit 10. Alternatively, all floors are not serviceable.

The operation control unit 12 determines whether or not the current time made by the rescueable time determination unit 14 is before the rescueable time and the service floor (including the service direction) managed by the service floor management unit 11. ) To control the operation of the car 1.
Other configurations are the same as the premise configuration described above, and detailed description thereof is omitted.

  The flowcharts of FIGS. 5 and 6 show the operation of the elevator control device according to the first embodiment, particularly when the operation mode is switched from the normal operation mode to the disaster operation mode when a tsunami is expected to arrive. This shows the operation. FIG. 5 is the first half of the flow showing the operation, and FIG. 6 is the second half of the flow showing the operation, and a series of flows is formed by combining these FIGS.

  First, at the start of this flow, the elevator operation mode is the normal operation mode. Then, in step S21, the tsunami information receiving means 5 includes information on the area where the tsunami is expected to arrive, the expected height of the tsunami, and the expected arrival time from the tsunami information distribution server 4 (Meteorological Agency server). Get tsunami information. In subsequent step S22, the tsunami information receiving means 5 inputs the tsunami information acquired in step S21 to the tsunami area determining means 7.

  In continuing step S23, the tsunami area determination means 7 acquires the address information of the building where the said elevator is installed from the building address storage means 6. FIG. Then, the tsunami area determination means 7 determines whether the location of the building is a tsunami target area, that is, an area where the location of the building is expected to reach the tsunami included in the tsunami information input in step S22 (tsunami It is determined whether it is within the forecast zone.

  If it is determined in step S23 that the location of the building is not a tsunami target area, the process proceeds to (C) in FIG. This (C) corresponds to the same reference numerals in FIG. Therefore, when it reaches (C) in FIG. 5, a series of operation | movement flow is complete | finished as shown in FIG. In this case, the operation mode of the elevator remains in the normal operation mode.

  On the other hand, if the location of the building is a tsunami target area in step S23, the control device main body 3 switches the elevator operation mode to the disaster operation mode, and then proceeds to step S24. Thereafter, steps S24 to S38 are operations in the disaster operation mode. In step S24, the tsunami area determination means 7 acquires the expected tsunami height and the expected arrival time of the tsunami in the tsunami forecast zone to which the location of the building belongs from the tsunami information. The obtained predicted tsunami height is stored in the tsunami height storage means 8. Further, the obtained estimated arrival time of the wave is stored in the tsunami arrival time storage means 13.

  In the subsequent step S25, the floor determination means 10 is first based on the predicted tsunami height stored in the tsunami height storage means 8 and the tsunami inundation prediction stored in the tsunami damage prediction storage means 9. Thus, a predicted value of the height of the tsunami when the tsunami reaches the location of the building where the elevator is installed is calculated. Then, the floor corresponding to the tsunami height is obtained from the predicted value of the tsunami height, and all floors above the floor one floor above the floor corresponding to the tsunami height are determined as evacuation floors.

  In the subsequent step S26, the service floor management means 11 includes the up direction button of the landing buttons 2 on the floor below the tsunami height equivalent floor (that is, the floor below the evacuation floor) and the destination button 1a in the car. The operation to the destination button corresponding to the evacuation floor is enabled (service available), and the operation to the other call registration buttons is disabled (service unavailable).

  In the following step S27, the rescueable time determination means 14 is first required for the car 1 to move from the lowest floor of the building to the evacuation floor (the lowest floor). Calculate travel time. Next, the rescueable time determination unit 14 obtains a time that is earlier than the estimated tsunami arrival time stored in the tsunami arrival time storage unit 13 by the travel time and determines the rescueable time. The determined rescueable time is stored in the rescueable time storage unit 15.

  In subsequent step S28, the rescueable time determination means 14 determines whether or not the current time is before the rescueable time obtained in step S27. If the current time is before the rescueable time, the process proceeds to step S29. When the user operates the landing button 2 on any floor in step S29, the operation control means 12 determines in step S30 whether the landing button 2 operated in step S29 is valid (serviceable). judge. If the operated hall button 2 is invalid (service is not possible), the process returns to step S28.

  On the other hand, when the operated hall button 2 is valid (service available), the process proceeds to (D) in FIG. This (D) corresponds to the same reference numerals in FIG. Therefore, when it reaches (D) in FIG. 5, it progresses to step S31 of FIG. In step S31, the operation control means 12 dispatches (runs) the car 1 to the floor where the landing button 2 operated in step S29 is installed.

  In subsequent step S32, the rescueable time determination means 14 determines again whether or not the current time is before the rescueable time obtained in step S27. If the current time is before the rescueable time, the process proceeds to step S33. In step S33, when the user gets on the car 1 that has arrived and operates the in-car destination button 1a, the process proceeds to step S34, where the operation control means 12 enables the in-car destination button 1a operated in step S33 (service). Or not). If the operated car destination button 1a is invalid (service is not possible), the process returns to step S32.

  On the other hand, if the operated car destination button 1a is valid (service available), the process proceeds to the next step S35. In step S35, the operation control means 12 causes the car 1 to travel to the floor corresponding to the car destination button 1a operated in step S33. As is clear from the above description, the destination floor of this car 1 is an evacuation floor. When the car 1 arrives at the evacuation floor, the user who has boarded the car 1 arrives at the evacuation floor (step S36), and the series of operation flow ends.

  On the other hand, when the current time has passed the rescueable time in step S28, the process reaches (E) in FIG. This (E) corresponds to the same reference numerals in FIG. Therefore, when it reaches (E) in FIG. 5, it progresses to step S37 of FIG. Moreover, also when the present time is over the rescueable time in step S32, it progresses to step S37.

  In step S37, the operation control means 12 causes the car 1 to travel to the evacuation floor. When there are a plurality of evacuation floors, one floor is selected as the destination floor of the car 1 from the plurality of evacuation floors. At this time, the conditions for selecting which evacuation floor can be set in advance. When the car 1 arrives at the evacuation floor, the service floor management means 11 disables all the floors (step S38), and the series of operation flow ends.

  In the above, when the rescue time determination unit 14 determines that the current time is before the rescue time (step S28), the user operates the landing button 2 on any floor (step S28). No particular mention was made of the movement of the car 1 until S29).

  About this point, after it is determined by the rescueable time determination means 14 that the current time is before the rescueable time, until the current time exceeds the rescueable time, or the landing button on any floor by the user Until car 2 is operated, the car 1 may be moved to a floor below the evacuation floor, and the car 1 may be placed on standby in the floor below the evacuation floor.

  By doing in this way, the user in the floor below the evacuation floor where the car 1 is waiting for door opening can smoothly evacuate using the elevator. In addition, if a call to a floor below the evacuation floor other than the floor where the car 1 is waiting for door opening is registered, the time required to dispatch the car 1 can be shortened. As a result, the time required for evacuation can be shortened.

  Then, when the current time has passed the rescueable time, the car 1 can be prevented from being damaged by tsunami by stopping the door open and closing the door to move the car 1 to the evacuation floor. it can.

  Further, the rescue time determination means 14 determines whether or not the rescue is possible using the time, but based on a specific time point (for example, when the tsunami information reception means 5 receives the tsunami information). By doing so, it can be determined whether or not the rescue is possible based on the elapsed time instead of the time.

  The elevator control device configured as described above includes a tsunami information receiving means for receiving tsunami information, and the building where the elevator is installed is a target area of the tsunami information based on the tsunami information received by the tsunami information receiving means. A tsunami area determination means for determining whether or not a building is included in the target area of the tsunami information, a tsunami arrival time storage means for storing a tsunami arrival time extracted from the tsunami information, and a building Tsunami height storage means for storing the height of the tsunami extracted from the tsunami information and the floor of the building higher than the tsunami height stored in the tsunami height storage means when included in the target area of the tsunami information Determining the evacuation floor and determining the evacuation floor and determining the rescueable time based on the tsunami arrival time stored in the tsunami arrival time storage means and determining whether or not the rescueable time has elapsed And available time determining means out, prior to the expiration of the rescue possible time is obtained and a service level management unit to enable an upward hall call at floor below the evacuation floor.

  For this reason, when a tsunami is expected to reach the building where the elevator is installed, the elevator can be used as much as possible to evacuate people in the building.

  Furthermore, after the rescueable time has elapsed, after moving the car to the evacuation floor, the service floor management means disables all floors so that the tsunami can reach the building where the elevator is installed. When it is predicted that the elevator car will reach, the elevator car can be evacuated to a floor that is not affected by the tsunami.

Embodiment 2. FIG.
FIGS. 7 and 8 relate to the second embodiment of the present invention, and are block diagrams showing the overall configuration of the elevator system including the elevator control device, and FIG. FIG.

  In addition to the configuration of the first embodiment described above, the second embodiment described here is further provided with a rest operation determining means for stopping the operation of the elevator after the current time exceeds the rescueable time. It is.

  That is, as shown in FIG. 7, the control device main body 3 further includes a pause operation determination means 16 in addition to the configuration of the first embodiment (FIG. 4). The rest operation determination unit 16 outputs a rest operation request to the operation control unit 12 when the rescue time determination unit 14 determines that the current time has passed the rescue time.

The operation control means 12 that has received the pause operation request from the pause operation determining means 16 first causes the car 1 to travel to the evacuation floor. When the car 1 arrives at the evacuation floor, the service floor management means 11 disables all floors. Then, in response to the fact that all floors are disabled, the operation control means 12 outputs a pause operation request to the car 1 to pause the car 1.
Other configurations are the same as those in the first embodiment, and detailed description thereof is omitted.

The flow of the operation stop operation in the elevator control device of this embodiment having the above-described configuration will be described in more detail with reference to FIG.
First, in step S <b> 41, the rescueable time determination unit 14 determines whether or not the current time is before the rescueable time stored in the rescueable time storage unit 15. If the current time is before the rescueable time, the series of operation flow ends.

  On the other hand, if the current time is past the rescueable time, the process proceeds to step S42. In step S <b> 42, the pause operation determination unit 16 outputs a pause operation request to the operation control unit 12. And it progresses to step S43, and the operation control means 12 which received the pause operation request makes the car 1 run to the evacuation floor. When there are a plurality of evacuation floors, one floor is selected as the destination floor of the car 1 from the plurality of evacuation floors. At this time, a condition for selecting which evacuation floor is set in advance.

  When the car 1 arrives at the evacuation floor, the service floor management means 11 disables all floors in step S44. Then, in the following step S45, the pause operation determination means 16 outputs a pause operation request to the car 1 to pause the car 1, and the series of operation flows ends.

  The elevator control apparatus configured as described above further includes a pause operation determination means for outputting a pause operation request for the elevator when the rescueable time has elapsed in the configuration of the first embodiment. When the operation control means receives the pause operation request, the operation control means moves the car to the evacuation floor and stops the operation.

  For this reason, in addition to being able to achieve the same effect as in the first embodiment, the elevator car is evacuated to a floor where the influence of the tsunami does not reach, and the car is damaged by the tsunami. Can be prevented.

  1 car, 1a car destination button, 2 landing button, 3 control device body, 4 tsunami information distribution server, 5 tsunami information receiving means, 6 building address storage means, 7 tsunami area determination means, 8 tsunami height storage means, 9 Tsunami damage prediction storage means, 10 floor determination means, 11 service floor management means, 12 operation control means, 13 tsunami arrival time storage means, 14 rescueable time determination means, 15 rescueable time storage means, and 16 rest operation determination means.
