  As shown in FIG. 2, an in-car operation panel 20 is provided inside each car 2. The in-car operation panel 20 includes an operation button 21, a display 22, and an interphone 23.

  The operation button 21 is a button operated by a user in the car 2 at the time of call registration for registering a desired destination floor. The operation button 21 is not particularly limited as long as the destination floor can be registered. For example, a button that displays the destination floor may be used.

  Further, the evacuation operation control unit 15 in the control device 10 to be described later performs an operation corresponding to the floor to which the evacuation guidance is performed so that the evacuation guide can know from which floor to what floor the evacuation guidance is performed. Display control is performed such that the button 21 is turned on or the operation button 21 is blinked by adjusting the flicker speed of the operation button 21 corresponding to the floor on which evacuation guidance is performed. Furthermore, the evacuation operation control unit 15 can also display the operation buttons 21 so that the fire occurrence floor can be specified.

  The display 22 displays elevator operation information. As specific display contents, for example, during normal operation, the traveling direction of the car 2 and the floor on which the car 2 is currently traveling are displayed on the display 22. Further, during an emergency operation such as a fire or an earthquake, fire or earthquake occurrence information directed to the user is displayed on the display 22.

  Further, according to the present invention, it is possible to cause the display 22 to display the content of how many floors to what floor the evacuation guidance is to be performed toward the evacuation guide. Moreover, it can also comprise so that the image | video of the boarding 3 acquired from the camera 4 can be directly displayed on the indicator 22 as needed.

  The intercom 23 is configured to be able to communicate with the management center by voice when an emergency button in the car 2 (not shown) is pressed. In the present invention, the evacuation guides or the evacuation guide and the user can exchange voices via the interphone 23 even between the cars 2.

  As the control device 10, an elevator control computer having a CPU, a ROM, a RAM, and a signal conversion device is used. The operation of the control device 10 is executed by the processor of the elevator control computer executing a program stored in the memory. Note that the control device 10 may be configured so that a plurality of processors and a plurality of memories execute in cooperation.

  As shown in FIG. 2, the control device 10 includes a fire-time operation control unit 11 that controls operation when a fire occurs. Here, the fire-time operation control unit 11 includes a user number estimation unit 12, an evacuation operation method determination unit 13, a service zone determination unit 14, an evacuation operation control unit 15, an in-car display control unit 16, and a door. An opening / closing control unit 17 and an intercom control unit 18 are provided.

  The fire operation control unit 11 starts fire operation control for utilizing the car 2 for evacuation guidance by receiving information on the occurrence of a fire from a fire alarm (not shown) installed in the building. To do. At this time, the fire-time operation control unit 11 acquires information on which floor of the fire alarm in the building has been activated, that is, information on the fire occurrence floor, and stores it in a storage unit (not shown).

  In addition, after starting the operation control at the time of fire, the number-of-users estimation unit 12 of the operation control unit 11 at the time of fire acquires the video of the hall 3 from the camera 4 provided in each of the halls 3 and waits for each hall 3 The number of users is estimated as the number of users information. The method of estimating the number of users executed by the number-of-users estimation unit 12 is not particularly limited. For example, the video acquired from the camera 4 is processed as a still image, and the floor area that is visible is stored in advance. A method of estimating by comparing with the total floor area is mentioned.

  The user number estimation unit 12 transmits the estimated user number information to the service zone determination unit 14. The service zone determination unit 14 determines a service zone for each car 2 from the number of users information received from the number-of-users estimation unit 12 and the driving method information received from the evacuation driving method determination unit 13. Here, the driving method information will be described in detail below.

The evacuation operation method determining unit 13 receives an evacuation operation method that is different depending on the number of evacuation guiders. When it is assumed that there are two cars, the following three methods are used as the evacuation operation method in the first embodiment.
(First method) Independent evacuation operation for each car by two evacuation guides: After confirming the situation where the evacuation guide is in each car, each car is driven independently and evacuation guidance is performed. It is.
(Second method) Car-linked evacuation operation by one evacuation guide: After confirming that the evacuation guide is in only one car, drive the other car in conjunction with one car. This is a method of conducting evacuation guidance.
(Third method) One-car evacuation operation by one evacuation guide: This is a method in which evacuation guidance is performed with only one car after confirming that the evacuation guide is on only one car.

  In each car independent evacuation operation according to the first method in which one evacuation guide is on each car 2, each car 2 is within the service zone appropriately assigned to the first method. , Evacuation guidance to the user's evacuation floor can be performed.

  In addition, in the car-linked evacuation operation by the second method, for example, if an evacuation guide is on only the lower car 2b, the upper car 2a arranged on a floor at a desired distance is linked to the lower car 2b. The user can guide the evacuation to the evacuation floor.

  That is, in the second method, the lower car 2b is operated for evacuation guidance within a service zone appropriately assigned to the second method, and a desired distance is separated from the operation of the lower car 2b. In this method, the upper car 2a is moved to the next floor, and evacuation guidance is performed using the upper car 2a and the lower car 2b.

  In addition, as an example, the one-cage evacuation operation by the third method is to move the upper car 2a to the terminal floor of the building and move only the lower car 2b if the evacuation guide is on only the lower car 2b. Thus, evacuation guidance can be performed to the evacuation floor of the user on the floor other than the terminal floor.

  That is, the third method is a method of performing evacuation guidance using only the lower car 2 within the service zone appropriately assigned to the third method.

  A method for determining the evacuation operation method will be described with reference to FIG. FIG. 3 is a flowchart showing a series of operations in which the evacuation guider determines the evacuation operation method.

  As shown in FIG. 3, in step S <b> 101, the evacuation operation control unit 15 enables communication between the cars via the intercom 23 based on an operation input from the evacuation guide. Here, in order to communicate between the cars 2 via the interphone 23, the evacuation guide on the lower car 2b needs to perform a desired operation. The desired operation is not particularly limited, and examples thereof include an operation of simultaneously pressing a predetermined number of the operation button 21 and the emergency button.

  When the evacuation operation control unit 15 receives a desired operation input for enabling communication via the interphone 23, the evacuation operation control unit 15 transmits an instruction for enabling communication between the cars 2 to the interphone control unit 18. As a result, the intercom control unit 18 can communicate between the cars 2.

  Next, in step S102, the evacuation driving method determination unit 13 receives an operation input from the evacuation guide based on the result of communication using the interphone, and determines which evacuation driving method should be adopted. Specifically, first, the evacuation guide gets into one of the cars 2 and communicates with the other car 2 through the intercom 23 to determine whether the evacuation guide is only one person or the other car. Also make sure that you are on board.

  Then, if it is confirmed that there are two evacuation guiders, the evacuation guide of the car 2 that started communication, that is, the evacuation guide of the lower car 2b, can be specified via the operation button 21. By performing the operation, an input for identifying whether or not to perform each car independent evacuation operation which is the first method is performed to the evacuation operation method determination unit 13.

  As a result, the evacuation operation method determination unit 13 receives the operation input for specifying the first method, and then proceeds to step S103 to set the evacuation operation method to each car independent evacuation operation.

  On the other hand, when it can be confirmed that there is only one evacuation guider, the evacuation guider determines the fire occurrence floor from the display state of the operation button 21 and judges from the position of the fire occurrence floor, and the car 2 Decide whether or not to drive with each other. This determination may be left to the evacuation guide or may be determined according to a preset manual.

  Based on the determined result, the evacuation guide performs input for enabling identification of the car-linked evacuation operation of the second method and the one-car evacuation operation of the third method. As a result, the evacuation operation method determination unit 13 receives an operation input for specifying the second method, and then proceeds to step S104 to set the evacuation operation method to the car-linked evacuation operation. On the other hand, the evacuation operation method determination unit 13 receives an operation input for specifying the third method, and then proceeds to step S105 to set the evacuation operation method to the one-car evacuation operation.

  The operation for specifying the first method to the third method is not particularly limited. For example, an operation for identifying by simultaneously pressing a plurality of predetermined numbers of the operation buttons 21 can be given.

  The evacuation operation method determination unit 13 transmits the evacuation operation method determined based on a specific operation input by the evacuation guide to the service zone determination unit 14 and the evacuation operation control unit 15 as operation method information.

  The service zone determination unit 14 determines each service zone of the car 2 based on the number of users information received from the user number estimation unit 12 and the driving method information received from the evacuation driving method determination unit 13. Generate information.

  Here, when the driving method information received from the evacuation driving method determination unit 13 is each car independent evacuation driving which is the first method or car linked evacuation driving which is the second method, the service zone determination unit 14 The service zone is determined based on the number of cars 2 in 1. That is, in the first embodiment, service zones for the upper car 2a and the lower car 2b are determined.

  In the first embodiment, in order to simplify the description, the service zone determination unit 14 sets the lowest floor of each service zone determined for each car as an evacuation floor, The case where the lowest floor of the car is a rescue floor where the user can go outside the building will be described.

  However, the evacuation floor does not necessarily have to be set at the lowest floor of each service zone, and the appropriate location corresponding to the actual building is taken into consideration, such as the actual rescue floor and the contact floor with other buildings. Can be set as an evacuation floor. For example, when there are two cars 2 and the service zone of the upper car 2a is from the fire occurrence floor + M floor to the top floor, the service zone determination unit 14 considers that smoke rises, Set the evacuation floor as one floor below the fire floor. Note that M is a natural number determined by the service zone determination unit 14.

  FIG. 4 is a diagram illustrating a specific example in which the service zone determination unit 14 determines the service zones of the upper car 2a and the lower car 2b when each car independent evacuation operation is adopted as the evacuation operation method. In Figure 4, the building is 12 floors, 5 on 11th floor, 2 on 8th and 9th floors, 1 on 7th floor, 4 on 4th floor, 8 on 3rd floor, 6 on 2nd floor There are users. Furthermore, the fire occurrence floor is the 6th floor, and the first floor is the rescue floor that can go out of the building.

  The service zone determination unit 14 first determines a temporary service zone. Here, the provisional service zone determination method is, for example, a service zone based on a method of determining a building divided by the number of cars 2 or the number of users for each hall 3 received from the user number estimation unit 12. There is a method for determining the number of people to be almost equal for each time.

  Here, in the first embodiment, the former method of determining the number of people in each service zone so as to be approximately equal is adopted as a provisional service zone determination method. In FIG. 4, it is estimated that the number of people on the fourth floor and above is 14 and the number of people on the first to third floors is 14 people. Accordingly, the fourth and higher floors are set as service zones for the upper car 2a, and the first to third floors are set as service zones for the lower car 2b. At this time, the evacuation floor of the upper car 2b is the fourth floor.

  Next, the service zone determination unit 14 acquires the current stop positions of the upper car 2a and the lower car 2b from a position detection device (not shown), for example, an encoder, and determines whether or not the temporarily determined service zone is appropriate. Check. FIG. 4 illustrates a case where the upper car 2a is stopped on the 11th floor and the lower car 2b is stopped on the second floor.

  In order to confirm whether or not the temporarily determined service zone is valid, the service zone determining unit 14 determines the rescue time until all users in the temporarily determined service zone move to the evacuation floor for each service zone. To calculate. After that, the service zone determination unit 14 compares the calculated rescue times in all the service zones, and if the difference in the rescue time is within a preset desired time range, the temporarily determined service zone is valid. It is judged that.

  That is, the service zone determination unit compares the rescue time for each service zone, and determines the service zone for each car so that the variation in the rescue time is within a preset allowable range.

  At this time, the service zone determination unit 14 also determines whether or not the lowest floor of the service zone of the upper car 2a among the service zones determined to be appropriate is a fire occurrence floor. When the lowest floor of the service zone of the upper car 2a is a fire occurrence floor, the service zone determination unit 14 sets the lowest floor of the service zone of the upper car 2a, that is, the evacuation floor, one more than the fire occurrence floor. Set to the lower floor.

  Therefore, when the evacuation floor of the upper car 2a is corrected, the service zone determination unit 14 adjusts the top floor of the service zone of the lower car 2b to be one floor below, and determines the final service zone. . In this way, the service zone determination unit 14 determines service zones so that the service zones for each car 2 do not overlap.

  Here, the rescue time is the car 2 that has arrived from the time when the car 2 is operated from the car position acquired from the position detection device and travels to the evacuation floor via the hall 3 and the number of users at the hall 3. Is calculated by totaling the time from when the door is opened until the user enters the car 2 and closes the door. When all users in the service zone cannot be guided to the evacuation floor at one time, the time when the car 2 is evacuated a plurality of times is also included in the rescue time.

  When the service zone determining unit 14 determines a service zone in which the difference in the rescue time of all the service zones is within a preset desired time range or the difference is the smallest, the service zone determination unit 14 The service zone information is transmitted to the evacuation operation control unit 15.

  That is, in FIG. 4, in the temporarily determined service zone, the upper car 2a stopped on the 11th floor evacuates the 11th, 9th, 8th, and 7th floor users to the 4th floor of the evacuation floor. It is determined that the rescue time required for the lower car 2b stopped on the second floor takes longer than the rescue time necessary to evacuate the third and second floor users to the first floor.

  And in this Embodiment 1, the upper cage | basket | car 2a stopped on the 11th floor stops on the 2nd floor, and the rescue time which evacuates the 11th floor, the 9th floor, the 8th floor, the 7th floor user to the 6th floor It is determined that the difference between the lower cage 2b and the rescue time for evacuating the users on the fourth floor, the third floor, and the second floor to the first floor is the smallest.

  Accordingly, the service zone of the upper car 2a is set on the 6th floor or higher, and the service zone of the lower car 2b is set on the 1st to 5th floors. At this time, the evacuation floor of the upper car 2a is set to the sixth floor. However, since the 6th floor is a fire occurrence floor, the upper car 2a is set to the 5th floor or higher, and the lower car 2b is set to the 1st to 4th floors in the final service zone. At this time, the evacuation floor of the upper car 2b is the fifth floor.

  On the other hand, when the driving method information received from the evacuation operation method determination unit 13 is a one-car evacuation operation, the service zone determination unit 14 stops the upper car 2a on the top floor and sets the service zone of the lower car 2b to 1 Decided from the first floor to the top floor – the first floor.

  The single car evacuation operation corresponds to a rescue operation using only one of the lower cars 2b if there is no user on the top floor.

  The evacuation operation control unit 15 performs evacuation operation control of the car 2 in the event of a fire based on the service zone information determined by the service zone determination unit 14 and the operation method information determined by the evacuation operation method determination unit 13. .

  Further, the evacuation operation control unit 15 generates and transmits a command to the in-car display control unit 16, the door opening / closing control unit 17, and the intercom control unit 18 based on the service zone information and the driving method information.

  Specifically, when the driving method information is each car independent evacuation operation or car-linked evacuation operation, the evacuation operation control unit 15 determines from the service zone information the operation button 21 of each car 2, the display 22, or In both cases, the in-car display control unit 16 sends service zone display information for displaying the service zone.

  Further, the evacuation operation control unit 15 sends the service zone display information to the in-car display control unit 16, and also sends the information on the fire occurrence floor from the storage unit to the in-car display control unit 16. As a result, the in-car display control unit 16 displays the operation buttons 21 and the display 22 based on the received service zone display information and fire floor information.

  That is, as a result of displaying the service zone in which the car 2 can be operated and the fire occurrence floor on the operation button 21 and the display 22 or both of the car 2, the evacuation guider can select an appropriate one based on the display state. Evacuation operation can be performed.

  Further, when the driving method information is the car-linked evacuation operation or the one-car evacuation operation, the evacuation operation control unit 15 obtains the number of users of the hall 3 assigned to the upper car 2a on which the evacuation guide is not on. Then, in order to display on the operation button 21 of the lower car 2b, the display 22 or both, "other car information" is generated and sent to the in-car display control unit 16. The in-car display control unit 16 displays the operation buttons 21 and the display 22 based on the received other car information.

  The evacuation operation control unit 15 also opens / closes the door interlocking information that enables the upper car 2a and the lower car 2b to be operated in conjunction with each other when the driving method information is car-linked evacuation driving. Transmit to the control unit 17. When the door opening / closing control unit 17 receives the door interlocking information, the operation button 21 of the lower car 2b is operated, so that the operation of the upper car 2a is performed in accordance with the lower car 2b.

  However, when the operation button 21 of the upper car 2a is operated while the upper car 2a and the lower car 2b are interlocked, the door opening / closing control unit 17 temporarily releases the interlock with the lower car 2b, The operation of the operation button 21 of the upper car 2a is prioritized. Thereby, even when a user who is not displayed on the evacuation guide of the lower car 2b comes to the landing 3 of the upper car 2a, the user can get on the upper car 2a by the operation of the user in the upper car 2a. .

  Next, an elevator control method executed by the control device 10 in each car independent evacuation operation will be described with reference to FIG. FIG. 5 is a flowchart showing a series of operations in which the fire-time operation control unit 11 performs each car independent evacuation operation.

  When the fire occurs, the control device 10 hands over the elevator operation to the fire operation control unit 11 from a normal operation control unit (not shown) that normally operates the elevator. At this time, each car 2 is stopped at the nearest floor.

  First, in step S201, the fire operation control unit 11 specifies the fire occurrence floor based on the reception result from the fire alarm and stores it in the storage unit. In step S201, at the same time, the user number estimation unit 12 of the fire operation control unit 11 acquires images from the cameras 4 provided in all the landings 3 in the building, and the number of users for each landing 3 And the number of users information is generated. This estimation process corresponds to a user number estimation step.

  After step S201, the process proceeds to step S202, where the service zone determination unit 14 sets a temporary service zone from the number of users information. Based on the temporary service zone set in step S202 and the number of users information, the service zone determination unit 14 calculates a rescue time for each temporary service zone in step S203.

  When the rescue time is calculated for each service zone in step S203, the service zone determination unit 14 determines in step S204 whether the difference in rescue time for each service zone is within a preset desired time range. Is detected.

  In step S204, when the difference in rescue time for each service zone is longer than the desired time range, the service zone determination unit 14 proceeds to step S205 and resets the temporary service zone.

  On the other hand, when the difference in the rescue time for each service zone is within the desired time range in the previous step S204, the service zone determination unit 14 determines the set temporary service zone as the service zone. Here, the service zone determination unit 14 sets the lowest floor of the determined service zone of the upper car 2a as the evacuation floor. In step S206, the floor set as the evacuation floor of the upper car 2a is the fire occurrence floor. Check if it exists.

  In step S206, if the evacuation floor of the upper car 2a is a fire occurrence floor, the service zone determination unit 14 proceeds to step S207, and sets the evacuation floor of the upper car 2a one floor below the determined floor. To do. On the other hand, in the previous step S206, if the evacuation floor of the upper car 2a is not a fire occurrence floor, the service zone determination unit 14 proceeds to step S208 and directly adopts the upper car 2a evacuation floor set in the previous step S204. To do. Steps S202 to S208 correspond to service zone determination steps.

  When the lowest floor of the determined service zone of the upper car 2a is higher than the fire occurrence floor, and the service zone determination unit 14 sets the evacuation floor to the fire occurrence floor minus the first floor, step In S206, it is confirmed whether or not the lowest floor of the service zone of the upper car 2a is higher than the fire occurrence floor. In such a step S206, if the lowest floor of the service zone of the upper car 2a is higher than the fire occurrence floor, the service zone determining unit 14 proceeds to the previous step S207. On the other hand, if the lowest floor of the service zone of the upper car 2a is below the fire occurrence floor, the service zone determination unit 14 proceeds to the previous step S208.

  The service zone determination unit 14 sends the determined service zone information to the evacuation operation control unit 15. Based on the service zone information, the evacuation operation control unit 15 displays the service zone of each car 2, the display of the fire occurrence floor, and the number of users for each landing 3, which are performed for the evacuation guide. Display information for this is transmitted to the in-car display control unit 16.

  In step S209, the car display control unit 16 displays the display information via the operation button 21, the display 22, or both. After displaying the display information for the evacuation guide in step S209, the evacuation operation control unit 15 enables each of the stopped cars 2 to be moved by the operation of the evacuation guide in step S210, and performs the evacuation operation. Start. This step S210 corresponds to an evacuation operation control step.

  When the evacuation operation control unit 15 starts the evacuation operation in the previous step S210, the evacuation instructor performs a desired operation on whether the evacuation is completed in both the upper car 2a and the lower car 2b in step S211. Check whether or not Here, the desired operation is not particularly limited, and examples thereof include an operation of pressing a predetermined number of the operation buttons 21.

  In step S211, when the information that the evacuation is completed is received, the process proceeds to step S212, and the evacuation operation control unit 15 moves the upper car 2a to the upper floor from the evacuation floor of the upper car 2a, and in the lower car 2b, A rescue operation is performed in which the user on the evacuation floor of the upper car 2a is moved to the first floor, which is the rescue floor. That is, after the movement to each evacuation floor is completed in each service zone, people who have evacuated to the evacuation floor assigned to the upper car 2a by using the upper car 2a are Move to the rescue floor.

  On the other hand, if the evacuation completion information is not received in step S211, the evacuation operation control unit 15 proceeds to step S213 and confirms whether the evacuation of either the upper car 2a or the lower car 2b is completed. To do. In step S213, when the evacuation of either the upper car 2a or the lower car 2b has been completed, the evacuation operation control unit 15 returns to the previous step S201 and determines the service zone again. At this time, until a new service zone is determined, the upper car 2a and the lower car 2b are evacuated while keeping the already determined service zone.

  On the other hand, if the evacuation of either the upper car 2a or the lower car 2b has not been completed in the previous step S213, the evacuation operation control unit 15 proceeds to step S214 and performs a desired time after starting the evacuation operation. Check if it has passed. Here, the desired time may be a preset time or a rescue time calculated by the service zone determination unit 14.

  In step S214, when a desired time has elapsed since the start of the evacuation operation, the evacuation operation control unit 15 is configured to promptly guide the user who is temporarily waiting on the evacuation floor of the upper car 2a to the rescue floor. Returning to step S201, the service zone is determined again. At this time, the evacuation operation control unit 15 performs the evacuation operation with the already determined service zone until a new service zone is determined by the service zone determination unit 14.

  Next, an elevator control method executed by the control device 10 in the car-linked evacuation operation will be described with reference to FIG. FIG. 6 is a flowchart showing a series of operations when the fire-time operation control unit 11 performs the car-linked evacuation operation.

  After the service zone determination unit 14 determines the service zone in the same manner as steps S201 to S208 in FIG. 5, the evacuation operation control unit 15 of the control device 10 performs the following operation in step S301. When the operation button 21 is operated by the evacuation guide who is in the car 2b, it is detected whether or not the vehicle allocation floor on which the lower car 2b should go to the evacuation guidance is determined.

  When the dispatch floor of the lower car 2b is determined in step S301, the evacuation operation control unit 15 proceeds to step S302, and dispatches a floor that is N floors above the dispatch floor of the lower car 2b, that is, the upper car 2a. It is detected whether there is a user on the planned floor.

  In addition, when the evacuation operation control unit 15 adopts the car-linked evacuation operation as the evacuation operation method, the method for determining the N floor corresponding to the distance between the upper car 2a and the lower car 2b is not particularly limited. For example, based on the number-of-users information determined by the number-of-users estimation unit 12, there is a method for determining that the upper car 2a is to be dispatched on the top floor where there are users in the service area of the upper car 2a. Further, N is updated in accordance with the movement of the lower car 2b, as will be described later.

  In step S302, if the evacuation operation control unit 15 determines from the number of users information that there is a user on the Nth floor above the car floor of the lower car 2b, the process proceeds to step S303, and from the car floor of the lower car 2b. N is set to the upper car dispatch floor on the Nth floor.

  On the other hand, if it is determined in the previous step S302 that there is no user on the N floor above the vehicle floor of the lower car 2b, the evacuation operation control unit 15 proceeds to step S304, and regardless of the service zone, The floor one level higher than the vehicle allocation floor of the lower car 2b is set as the upper car allocation floor. If the floor one floor above the lower car 2b is the fire-breaking floor, the evacuation operation control unit 15 dispatches the upper car two floors above the lower car 2b. Set to the floor.

  The evacuation operation control unit 15 moves the lower car 2b to the floor allocation floor of the lower car 2b set by the evacuation guide, and sets the upper car 2a to the upper car allocation floor determined in the previous step S303 or the previous step S304. Move.

  Thereafter, in step S305, the evacuation operation control unit 15 detects whether or not the upper car 2a has stopped at the upper car dispatch floor. In step S305, when the upper car 2a arrives at the upper car allocation floor, the evacuation operation control unit 15 proceeds to step S306, and the evacuation guide boarding the lower car 2b is assigned to the upper car 2a allocation floor. The state of the hall 3 is displayed via the in-car display control unit 16 and the display 22.

  After the previous step S306, the evacuation operation control unit 15 detects in step S307 whether or not the door opening operation of the upper car 2a has been executed from the operation button 21 of the lower car 2b by the evacuation guide.

  That is, the evacuation guide confirms the evacuation state of the upper car 2a together with the lower car 2b being rescued, based on the display content in step S306. When the evacuation guider determines from the information displayed on the display 22 that there is a user on the upper car 2a, the evacuation guide operates the operation button 21 on the lower car 2b to thereby open the door of the upper car 2a. When it is determined that there is no user, it is determined in step S307 not to open the door of the upper car 2a.

  Therefore, if the door opening operation is not performed within the preset time in the previous step S307, the evacuation operation control unit 15 proceeds to step S308 and waits with the upper car 2a closed. Then, the process proceeds to step S312.

  On the other hand, if the evacuation guider determines from the information displayed on the display 22 that there is a user who gets on the upper car 2a, the evacuation guide performs a desired operation on the operation button 21 of the lower car 2b. Close the door of 2a and wait. Here, the desired operation is not particularly limited, and examples thereof include an operation of pressing a predetermined number of the operation button 21 and a door opening button of the operation button 21.

  Accordingly, if a desired operation is performed in the previous step S307, the evacuation operation control unit 15 proceeds to step S309, and opens the door of the upper car 2a to wait. At the same time, the evacuation guider can guide the user to get inside the upper car 2 a through the intercom 23.

  Further, after step S309, the evacuation operation control unit 15 determines in step S310 that the door closing operation of the upper car 2a has been executed by the evacuation guide from the operation button 21 of the lower car 2b within a predetermined time. Detect whether or not.

  That is, the evacuation guide confirms the state of the upper car 2a from the display 22 along with the guidance of the user of the lower car 2b to the lower car 2b, or the user of the upper car 2a receives the upper car via the interphone 23. It is confirmed whether boarding in 2a is completed.

  When the evacuation guider determines that the user of the upper car 2a has successfully boarded the upper car 2a, the evacuation guide performs a desired operation on the operation button 21 of the lower car 2b, so that the upper car 2a Close the door. Here, the desired operation is not particularly limited, and examples thereof include an operation of pressing a predetermined number of the operation button 21 and a door closing button of the operation button 21.

  Accordingly, if the door closing operation is performed within the predetermined time in the previous step S310, the evacuation operation control unit 15 proceeds to step S311, closes the door of the upper car 2a, and then proceeds to step S312.

  After step S311, the evacuation operation control unit 15 confirms in step S312 whether or not the user of the upper car 2a has performed the door opening operation from the operation button 21 in the upper car 2a.

  If it is determined in step S312 that the user of the upper car 2a has performed the door opening operation from the operation button 21 in the upper car 2a, the evacuation operation control unit 15 proceeds to step S313, and the door from the lower car 2b is moved. The closing operation is invalidated and the door of the upper car 2a is opened.

  When the door of the upper car 2a is opened in step S313, the evacuation operation control unit 15 returns to the previous step S310, and the door closing operation is again executed by the evacuation guide by the operation button 21 of the lower car 2b. It is detected whether or not.

  On the other hand, if it is determined in the previous step S312 that the user of the upper car 2a has not performed the door opening operation from the operation button 21 in the upper car 2a, the process proceeds to step S314, and the evacuation operation control unit 15 is performed. Detects whether both the upper car 2a and the lower car 2b are in the door-closed state. Thereafter, in step S315, the evacuation operation control unit 15 confirms the input of the moving floor from the evacuation guide who is in the lower car 2b.

  In step S315, if the evacuation guide selects a floor other than the lower car evacuation floor from the operation button 21, the evacuation operation control unit 15 returns to the previous step S301 and repeats the series of processes.

  On the other hand, in the previous step S315, when the evacuation guide selects the lower car evacuation floor from the operation button 21, the evacuation operation control unit 15 moves the upper car 2a and the lower car 2b to the evacuation floor, respectively. Let

  Thereafter, although not shown, when all the users in the service area of the upper car 2a complete the evacuation to the upper car evacuation floor, the upper car 2a is moved from the evacuation floor of the upper car 2a as in step S212 of FIG. Is also moved to the upper floor, and the rescue operation is performed in the lower car 2b to move the user on the evacuation floor of the upper car 2a to the first floor, which is the rescue floor.

  In steps S301 to S315, the evacuation guide is on the lower car 2b, but the same concept can be applied to the case where the evacuation guide is on the upper car 2a, and the description thereof is omitted.

  Next, an elevator control method executed by the control device 10 in the one-car evacuation operation will be described with reference to FIG. FIG. 7 is a flowchart showing a series of operations in which the fire-time operation control unit 11 performs the one-car evacuation operation.

  As shown in FIG. 7, in the one-car evacuation operation, unlike each car-independent evacuation operation and the car-linked evacuation operation, the service zone determination unit 14 determines the service zone stored in advance without calculating the service zone. To do.

  Accordingly, the evacuation operation control unit 15 first determines whether or not the upper car 2a door needs to be opened in step S401 in order to suspend the upper car 2a on the top floor. This is because the evacuation guide checks whether there is a user in the upper car 2a via the interphone 23 or the display 22, and if there is a user in the upper car 2a, This is because it is necessary to open the door once.

  In step S401, when there is no passenger in the upper car 2a, when receiving information indicating that the door opening operation of the upper car 2a is unnecessary from the evacuation guide, the evacuation operation control unit 15 selects the upper car 2a. It is determined that there is no need to open the door, and the process proceeds to step S403 described below.

  On the other hand, in the previous step S401, since there are passengers in the upper car 2a, when the evacuation guide receives information indicating that the door opening operation of the upper car 2a is necessary, the evacuation operation control unit 15 Open the door of the upper car 2a and get off the user. At this time, the evacuation guide may make an announcement to the user through an interphone, or an automatic announcement may be made.

  After opening the door of the upper car 2a, the evacuation operation control unit 15 proceeds to step S402 and determines whether or not the door of the upper car 2a is closed after all the users get off the upper car 2a.

  In step S402, when the door closing operation of the upper car 2a is completed, the evacuation operation control unit 15 proceeds to step S403, and moves the upper car 2a to the top floor. When the upper car 2a is moved to the top floor in step S403, the evacuation operation control unit 15 stops the operation of the upper car 2a in step S404.

  Thereafter, in step S405, the evacuation operation control unit 15 performs a rescue operation from the lowermost floor to the next lowermost floor using the lower car 2b. In step S406, the evacuation operation control unit 15 completes the rescue operation when notified from the evacuation guide that the rescue operation has been completed.

  Note that the following operation can be considered when there is a user at the landing on the top floor in the single car evacuation operation. That is, when it is determined that the user on the top floor is a healthy person, guidance is given by an announcement or the like to move to the lower floor using the stairs, and the rescue operation is performed according to the flowchart of FIG. On the other hand, if it is determined that the user on the top floor has a weak person such as a wheelchair, the upper car 2a is used to guide the user to the lower floor, and then the rescue operation using the lower car 2b is executed.

  The elevator control apparatus according to the first embodiment has a user number estimation unit that can estimate the user number information that is the number of users for each hall from the cameras installed in the halls. Moreover, the elevator control apparatus has a service zone determination unit that determines a service zone for each car from the evacuation operation method determined according to the number of evacuation guiders and the number of users information.

  In addition, the service zone determination unit compares the rescue time for each service zone, so that the difference in the rescue time is within a desired time range set in advance or is minimized, A service zone has been determined.

  By providing such a configuration, in the evacuation operation performed when a fire occurs, an appropriate rescue operation using a one-shaft multi-elevator can be executed according to the situation of the user at the landing when the fire occurs.

  In addition, since there is no significant difference in the rescue time for each service zone, even when there are a plurality of evacuation floors according to the number of cars, all users are moving to the evacuation floor almost simultaneously. Thereby, all users can be guided to the rescue floor in a shorter time.

  In addition, since the service zone determination unit determines the service zone so that the service zones of each car do not overlap, each car can perform evacuation operation without worrying about the movement of other cars. . Thereby, a user can be smoothly guided to an evacuation floor.

  In addition, the elevator control device has a configuration capable of operating the other car in conjunction with one car based on the number-of-users information. In accordance with this, the elevator control device has a configuration that performs door opening / closing control of one car in conjunction with one car. By providing such a configuration, even when there is one evacuation guider, the user can be guided to the evacuation floor in a shorter time.

  In the first embodiment, the case where the upper car 2a and the lower car 2b are arranged in the same shaft 1 has been described as an example. However, three or more cars are arranged in the same shaft 1. May be.

  In the first embodiment, an elevator with a machine room is described as an example. However, the present invention can be applied to an elevator without a machine room, and the same effect can be obtained. .
