Description

  The present invention relates to an elevator rescue operation system that performs a rescue operation using an elevator of each unit when a disaster such as a fire occurs in a building.

  With the recent rise of buildings, the elevator plays an indispensable role as a means of moving the building vertically. Elevators also play an important role for people with physical disabilities, such as wheelchair users, to move from floor to floor.

  Here, in the event of a fire, there is currently an operation such as stopping the operation after traveling the elevator to the evacuation floor, and there is no legal restriction, but the elevator is actively used as an evacuation means. There is no current situation. For this reason, people who remain in the building must use the stairs to move to the evacuation floor, take time to evacuate, and have the risk of injury by falling on the stairs.

  Therefore, in recent years, there has been an increasing demand for positively using elevators as evacuation means in the event of a fire. For example, Patent Document 1 discloses a method of guiding an inhabitant to an evacuation floor using an elevator when a fire occurs.

JP 2008-184301 A

  In a large building, a plurality of elevators are installed, and each elevator is divided into groups (referred to as banks) to efficiently control operation according to the usage situation of the user. In particular, high-rise buildings are divided into low-rise banks and high-rise banks to enhance transportation capacity and optimize waiting times.

  Here, when a fire breaks out, the fire usually spreads in the upward direction, so it is necessary to bring the people on the higher floor to the evacuation floor as soon as possible. However, in buildings that are divided into banks for high-rise and low-rise buildings, it takes time for the elevator for high-rise bank to go around between the high-rise floor and the evacuation floor (for example, 1F). There was a problem that the evacuation was delayed when a person remained.

  The present invention has been made in view of the above points. When a disaster such as a fire occurs in a building in which a plurality of elevators are divided into banks, a large number of people can be moved to a safe place as soon as possible. An object of the present invention is to provide an elevator rescue operation system that can be efficiently transported.

An elevator rescue operation system according to the present invention is an elevator rescue operation system used in a building having a plurality of elevators that are group-managed in at least two banks with different response zones. A disaster occurs in the building. Disaster detection means for detecting the occurrence location, a dangerous floor setting means for determining a dangerous floor based on the disaster occurrence location detected by the disaster detection means, and a danger set by the danger floor setting means Change the destination floor of the elevator where the floor is in the own bank response zone and the floor below the dangerous floor to the elevator of another bank from the preset evacuation floor to the above connection floor, and operation control means for controlling the operation of the elevator so as to circulate between the transit floor and the risk floor, are in the risk floor Rescue capable of calculating the number of people in the building and the time required to carry all the people calculated by the number of people in the building from the dangerous floor to the evacuation floor A time calculation means, and a waiting time calculation means for calculating the waiting time of the transit floor, wherein the operation control means is configured such that the time calculated by the rescueable time calculation means is greater than a preset first time. The elevator floor is changed from the evacuation floor to the connecting floor, and the waiting time of the connecting floor calculated by the waiting time calculating means is longer than a preset second time. If the waiting time of the transfer floor becomes longer than the second time when it becomes longer, change the destination floor of the elevator from the transfer floor to the evacuation floor and And controlling the operation of the elevator so as to direct operation to the evacuation floor.

An elevator rescue operation system according to another aspect of the present invention is used in a building having a plurality of elevators that are group-managed in at least two banks having different response zones. In an elevator rescue operation system in which there are at least two connecting floors with elevators in other banks, when a disaster occurs in the building, a disaster detection means for detecting the occurrence location, and this disaster detection means The dangerous floor setting means for determining the dangerous floor based on the place where the disaster occurred and the dangerous floor set by the dangerous floor setting means are in the response zone, and other banks are located below the dangerous floor. The destination floor of the elevator having the first transfer floor with the elevator is changed from the preset evacuation floor to the first transfer floor, and the above A first operation control means for controlling the operation of the elevator so as to circulate between one transit floor and the dangerous floor; and a first waiting time calculation means for calculating a waiting time of the first transit floor. And when the waiting time calculated by the first waiting time calculating means is longer than the preset first time, the second floor in which the destination floor of the elevator is below the first connecting floor A second operation control means for controlling the operation of the elevator so as to circulate between the second transfer floor and the dangerous floor, and a waiting time for the second transfer floor And a second waiting time calculating means for calculating the waiting time calculated by the second waiting time calculating means is longer than a preset second time. If the elevator eyes above Floor to change to the evacuation floor from said second transit floor, and controls the operation of the elevator so as to direct operation from the danger floor to the evacuation floor.

  According to the present invention, in a building where a plurality of elevators are divided into banks, for example, when a disaster such as a fire occurs on a high floor, the destination floor of the elevator for the high bank is changed from the evacuation floor to the connecting floor and As a result, the lap time of the elevator for the high-rise bank can be shortened, and a large number of people can be efficiently transported to a safe place as soon as possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of an elevator rescue operation system according to a first embodiment of the present invention. In the example of FIG. 1, the configuration of a system in which three elevators are group-managed and divided into a low-rise bank and a high-rise bank is shown. In addition, the elevator said here is a passenger car fundamentally, and when there are two or more sets, it is also called the number machine.

  This system includes a group management control device 11a for a low-rise bank, a group management control device 11b for a high-rise bank, a fire detection device 12, a notification device 13, and a single control device 14a, 14b, 14c, 14d, 14e, 14f, elevator cars 15a, 15b, 15c, 15d, 15e, 15f, and hall call buttons 16a, 16b, 16c ..., 17a, 17b, 17c ...

  The group management control device 11a for the low-rise bank performs group management control of each elevator in the low-rise bank. The group management control device 11b for the high-rise bank performs group management control of each elevator in the high-rise bank. Each of these group management control devices 11a and 11b is configured by a computer.

  The fire detection device 12 is installed on each floor of the building, detects the occurrence of a fire, and notifies the group management control devices 11a and 11b of the occurrence location. The notification device 13 notifies an evacuation warning or the like when the fire detection device 12 detects the occurrence of a fire.

  The single control devices 14a, 14b, and 14c are devices that individually control the operation of the elevators of each car in the low-rise bank, and perform, for example, car call registration and door opening / closing. Similarly, the single control devices 14d, 14e, and 14f are devices that individually control the operation of the elevators of each unit in the high-rise bank, and for example, register car calls and open / close doors. These single control devices 14a, 14b, 14c, 14d, 14e, and 14f are also configured by a computer in the same manner as the group management control devices 11a and 11b.

  The cars 15a, 15b, and 15c move up and down in the hoistway by driving a hoisting machine (not shown) in the low-rise bank, and move between the floors with passengers. Similarly, the cars 15d, 15e, and 15f move up and down in the hoistway by driving a hoisting machine (not shown) in the high-rise bank, and move between the floors with passengers.

  Also, hall call buttons 16a, 16b, 16c,... Are installed at halls on each floor in the low-rise bank. By operating the hall call buttons 16a, 16b, 16c..., A hall call signal including information indicating the floor and destination direction of the hall is sent to the low-level group management control device 11a. Thereby, in the group management control apparatus 11a for low-rise, the elevator which should assign the said hall call based on the driving | running state of the elevator of each No. unit is selected and made to respond.

  Similarly, hall call buttons 17a, 17b, 17c... Are installed at halls on each floor in the high-rise bank. By operating the hall call buttons 17a, 17b, 17c,..., A hall call signal including information indicating the floor and destination direction of the hall is sent to the high-rise group management control device 11b. Thereby, in the group management control apparatus 11b for high-rises, the elevator which should assign the said hall call based on the driving | running state of the elevator of each No. unit is selected and made to respond.

  Here, in this embodiment, the elevators of each unit are divided into banks for low-rise buildings and high-rise buildings, and each operates between different floors (see FIG. 4). The group management control devices 11a and 11b are provided with a control unit 21 and a storage unit 22 for group management of the elevators of each banked vehicle.

  Since the group management control devices 11a and 11b have the same configuration, each component will be described with the same reference numeral.

  The control unit 21 performs processing related to elevator operation control of each unit. Here, the dangerous floor setting unit 21a, the operation control unit 21b, the number of people in the building calculation unit 21c, the rescueable time calculation unit 21d, the waiting It has a time calculation unit 21e, a remaining number calculation unit 21f, and a notification unit 21g.

  The dangerous floor setting unit 21a determines a dangerous floor based on the location of the fire detected by the fire detection device 12. In this case, since the fire tends to spread upward in the building, the floor where the fire occurred and the floor above the floor are generally determined as dangerous floors.

  The operation control unit 21b determines that the dangerous floor set by the dangerous floor setting unit 21a is in the own bank response zone, and the elevator floor has a connection floor with an elevator of another bank below the dangerous floor. Is changed from the preset evacuation floor to the transfer floor, and the operation of the elevator is controlled so as to go around between the transfer floor and the dangerous floor.

  The “own bank response zone” refers to an elevator response zone when viewed from the group management control device corresponding to each bank. If it is the defined range, the group management control device 11b for high-rise, it is the range defined as the high-rise zone (see FIG. 4).

  The number-of-residents calculation unit 21c calculates the number of people in the dangerous floor. The rescueable time calculation unit 21d calculates the time required to carry all the people in the building calculated by the number of people in the building 21c to the evacuation floor. The waiting time calculation unit 21e calculates the waiting time of the transfer floor. The remaining number calculating section 21f calculates the number of people in the building (remaining number) remaining on the dangerous floor. When the destination floor of the elevator is changed, the notifying unit 21g notifies the passenger in the car and the landing on each floor.

  The storage unit 22 stores various information necessary for operation control of the control unit 21. The storage unit 22 is provided with a bank data storage unit 22a that stores data relating to the bank configuration. The data related to the bank configuration above includes data on low-rise zone ranges and elevator units responding to them, high-rise zone ranges and elevator unit responses to them, as well as floor data such as transit floors and evacuation floors. It is.

  FIG. 2 is a diagram showing the configuration of the elevator car.

  A car door 31 is provided on the front of the car 15 so as to be openable and closable, and an operation panel 32 provided with various operation buttons is provided beside the car door 31. The operation panel 32 is provided with a door opening button 34a, a door closing button 34b and the like in addition to a destination floor designation button 33 for a passenger to designate a destination floor.

  In the car 15, a display 35 for displaying a message and a speaker 36 for making a voice announcement are installed.

  FIG. 3 is a diagram showing the configuration of the elevator hall.

  A landing door 41 is provided at the elevator landing 17 so as to be freely opened and closed. The landing door 41 engages with the car door 31 and opens and closes when the car 15 is landed. A landing call button 40 is provided in the vicinity of the landing door 41. In the example of FIG. 1, the hall call buttons 40 are indicated by 16a, 16b, 16c... For the low-rise bank and 17a, 17b, 17c.

  The hall call button 40 is an operation button for registering a hall call, and specifically includes an upper direction designation button and a lower direction designation button for designating a destination direction. In addition to the hall call button 40, a hall call button 42 dedicated for wheelchair users is provided. The hall call button 42 is disposed at such a height that it can be operated while sitting in a wheelchair.

  An indicator 43 for displaying the current car position and the like is provided on the landing door 41. Further, a display 44 for displaying a message and a speaker 45 for making a voice announcement are installed near the landing door 41.

  Next, the operation of this system will be described.

  Now, as shown in FIG. 4, a system is assumed in which six elevators are arranged in parallel in buildings of 1F to 20F. The six elevators are referred to as “A”, “B”, “C”, “D”, “E”, and “F”, respectively, and the elevator cars 15a, 15b, 15c, 15d correspond to the example of FIG. , 15e, 15f.

  Each elevator is divided into banks for low-rise and high-rise buildings. Here, Unit A, Unit B, and Unit C operate as lower-level bank elevators in a range below a predetermined floor, that is, low-rise zones (1F to 11F). , E and F operate as a high-rise bank elevator in a range above a predetermined floor, that is, high-rise zones (11F to 20F) and 1F.

  1F and 11F are common floors for low-rise bank elevators and high-rise bank elevators. 1F is used as an evacuation floor in the event of a fire, and 11F is used as a connection floor between low-rise bank elevators and high-rise bank elevators. Is done.

  In addition, in a low-rise bank, it becomes a non-stop floor between 12F-20F, and cannot physically land on these floors. On the other hand, in a high-rise bank, it becomes a non-stop floor between 2F-10F, and it cannot physically land on these floors.

  In such a configuration, the A, B, C, which are elevators for low-rise banks, and the D, E, F, which are elevators for high-rise banks, are usually individually responded to landing calls on each floor. I'm driving. Here, in the event of a fire on the higher floors, in order to efficiently bring down a large number of people on the higher floors, the elevators for high-rise banks are specially designed with the connecting floor as the target floor in the event of a fire. Operation is performed.

The specific operation process will be described below.
FIG. 5 is a flowchart showing the operation process when a fire occurs in this system. The processing shown in this flowchart is executed in each of the group management control device 11a for the low-level bank and the group management control device 11b for the high-level bank.

  In the following, it is assumed that a fire has occurred in the high-rise zone, and the process executed mainly on the group management control device 11b side for the high-rise bank will be described.

  When a fire occurs in the high-rise zone in the building, the fire detection device 12 detects the fire occurrence place (floor where the fire has occurred), and the detection signal is given to the group management control device 11b for the high-rise bank (step S10). ). Thereby, the control part 21 provided in the group management control apparatus 11b performs the following operation processes.

  That is, the control unit 21 includes a floor where a fire has occurred and determines a floor above it as a dangerous floor (step S11). Then, the control unit 21 determines whether or not the dangerous floor is within the own bank response zone (step S12 (1)). In the case of a high-rise bank, since the dangerous floor is within the own bank response zone, the answer is Yes. In the case of a low-rise bank, No is given because the dangerous floor is outside the own bank response zone.

  Next, the control unit 21 determines whether or not there is a transit floor on the way from the dangerous floor to the first floor that is the evacuation floor (step S12 (2)). Here, in the case of a high-rise bank, since there is a transfer floor to a low-rise bank, it becomes Yes. However, even in a high-rise bank, if the building does not have a transfer floor to a low-rise bank, the answer is No.

  If the answer is No in step S12 (1) or S12 (2), a normal evacuation operation is performed using the low-rise bank elevator and the high-rise bank elevator (step S13).

  In the normal evacuation operation, the low-rise bank elevator and the high-rise bank elevator are each operated toward the 1F evacuation floor. During the evacuation operation, the evacuation floor on the 1st floor is automatically registered, and the car call registration on other floors is prohibited. In addition, landing calls can be arbitrarily registered on each floor.

  On the other hand, if the answer is Yes in steps S12 (1) and S12 (2), the control unit 21 obtains the number of people in the dangerous floor (step S14) and the people in the room. The time required to carry all the members from the dangerous floor to the 1F evacuation floor using the high-rise bank elevator is calculated (referred to as rescue time) (step S15).

  For example, as shown in FIG. 4, if a fire occurs on 17F, 17F to 20F are determined as dangerous floors, and the number of people on the floors is obtained.

  As a method for detecting the number of people in the building, for example, a camera is installed at a predetermined location on each floor, and the number of people in the building on each floor is detected from the image of the camera, or for each floor There is a method in which the number of passengers and the number of people getting off are recorded, and the number of people currently present on each floor is detected based on the recorded results. The number of passengers and the number of passengers can be estimated from changes in the load on the car.

  Further, when a security system having a function of performing personal authentication of a visitor with an ID card or the like is installed in a building, the number of people in each floor may be acquired from the security system.

  Here, the rescue possible time is approximately obtained based on the speed of the elevator for the high-rise bank, the rated number of persons, the number, and the distance from the dangerous floor to the evacuation floor. When the rescueable time is within a preset time Ta (for example, 5 minutes) (No in Step S16), the control unit 21 performs the normal evacuation operation as it is (Step S13).

  On the other hand, when the rescueable time exceeds a preset time Ta (for example, 5 minutes) (Yes in step S16), the control unit 21 determines that it is necessary to shorten the lap time of the high bank elevator. Then, the destination floor of the elevator for the high-rise bank at the time of evacuation is changed from the preset evacuation floor to the connecting floor and the special operation is executed (step S17).

  In the example of FIG. 4, the connecting floor with the elevator for the low-rise bank is 11F. Therefore, the elevators No. D, No. E, No. F, which are elevators for high-rise banks, are turned up after moving to 11F during evacuation.

  During special operation, the 11th floor transit floor is automatically registered and car call registration on other floors is prohibited. For the hall call, only the dangerous floor may be registered, or each floor in the high-rise zone including the dangerous floor may be registered. If only the dangerous floor can be registered for the hall call, the residents in the lower floors in the high-rise zone will use the stairs to go to the connecting floor. After that, when the number of people in the dangerous floor has decreased to some extent, it may be returned to a state where the hall call of each floor can be registered.

  Further, during the special operation, the control unit 21 notifies the car 15 and the landing 17 that the destination floor of the elevator for the high-rise bank has been changed to the transit floor (step S18). The notification method may be a message display or voice.

  FIG. 6 is a diagram showing a message display example of the display 35 installed in the elevator car 15 for the high-rise bank.

  When the elevator for the high-rise bank is in a special operation, the display 35 displays that the destination has been changed to the transit floor instead of the evacuation floor, and that the transit floor is safe for a while. Thereby, the anxiety of the occupant who got on the elevator for high-rise banks can be removed. At the same time, the speaker 36 may notify the same message by voice.

  FIG. 7 is a diagram showing a message display example of the display 44 installed at the landing 17 on each floor in the high-rise zone.

  When the elevator for the high-rise bank is in a special operation, the display 44 displays that the turn-up operation is currently being performed on the transfer floor at the landing 17 of each floor in the high-rise zone. As a result, it is possible to reassure the residents who are waiting at the landing 17 by informing them that they will return at the transit floor in advance. At the same time, the speaker 44 may notify the same message by voice.

  If the hall call is not registered within a certain time in the high-rise zone (Yes in step S19), the control unit 21 determines that there is no resident in the high-rise zone, and the elevator for the high-rise bank The operation is stopped (step S20).

  At this time, the low-rise bank elevator is in operation, and the high-rise bank elevator can carry the people who have come to the transfer floor to the evacuation floor on the first floor. At that time, if the operation is controlled so that the elevator for the low-rise bank is made to stand by at the transfer floor, the transfer from the elevator for the high-rise bank to the elevator for the low-rise bank becomes smooth on the transfer floor, and the people in the building can be moved to the first floor faster. Can be transported to the evacuation floor.

  In this way, when a fire occurs in the high-rise zone, by changing the target floor of the high-rise bank elevator to the transfer floor and operating, the lap time of the high-rise bank elevator is shortened and remains on the dangerous floor. A large number of residents can be efficiently transported to a safe place (transfer floor) as soon as possible.

  In the above embodiment, the dangerous floor at the time of evacuation is defined as the floor where the fire broke out and the floor above it, but several floors below the floor where the fire broke out are included in the dangerous floor It may be. However, on the floor close to the transfer floor, if the elevator for a high-rise bank is folded back on the transfer floor, the driving efficiency is poor, so if the dangerous floor is in the high-rise zone and close to the top floor (from the top floor to the specified floor) It is preferable to switch to special operation when it is within the range of minutes.

  Moreover, although the said embodiment demonstrated as what carries out special operation of all the D machines, E machines, and F machines which are elevators for high-rise banks, you may carry out at least 1 special operation.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  During special operation of high-rise bank elevators, it may take time to transfer to low-rise bank elevators because many people are concentrated on the transfer floor. In the second embodiment, the destination floor of the elevator for the high-rise bank is changed from the transit floor to the evacuation floor in accordance with the waiting time at the transit floor in order to eliminate such a mixed situation on the transit floor during special operation. It is what I did.

  The detailed processing operation will be described below.

  FIG. 8 is a flowchart showing processing operations during special operation of the rescue operation system for elevators according to the second embodiment of the present invention. In addition, since the process until the special operation of the elevator for high-rise banks is performed at the time of a fire occurrence is the same as that of FIG. 5, only the process in special operation is demonstrated here.

  When the elevator for the high-rise bank is performing a special operation, the control unit 21 of the group management control device 11b calculates the waiting time for the transfer floor (step S21). The waiting time can be obtained by counting the elapsed time from when the hall call is registered on the transit floor until the elevator for the low-rise bank responds. In the example of FIG. 4, 11F is a transit floor, and the time until the A, B, and C, which are elevators for low-rise banks, respond to the 11F hall call is determined as a waiting time.

  Here, when the waiting time is longer than a preset time Tb (for example, 1 minute) (Yes in step S22), the control unit 21 determines that the connecting floor is congested and is used for a high-rise bank. The elevator is operated directly to 1F, which is the evacuation floor, without stopping at the transit floor (step S23). At this time, the control unit 21 notifies the car and the hall of the current driving information so that the resident is not confused (step S24).

  In addition, during the direct operation to the evacuation floor, when the waiting time on the transfer floor is eliminated within a predetermined time, the target floor of the elevator for the high-rise bank may be returned to the transfer floor and special operation may be performed.

  In this way, when the connecting floor is congested, the destination floor of the elevator for the high-rise bank is changed to the first floor, which is the evacuation floor, and switched to direct operation, thereby avoiding the congestion situation on the connecting floor. People can be evacuated quickly.

(Third embodiment)
Next, a third embodiment of the present invention will be described.

  The third embodiment eliminates the mixed situation on the transfer floor by carrying the shuttle operation between the transfer floor and the evacuation floor after carrying the residents in the dangerous floor to the transfer floor by the elevator for the high-rise bank To do.

  The detailed processing operation will be described below.

  FIG. 9 is a flowchart showing a processing operation during special operation of the rescue operation system for an elevator according to the third embodiment of the present invention. In addition, since the process until the special operation of the elevator for high-rise banks is performed at the time of a fire occurrence is the same as that of FIG. 5, only the process in special operation is demonstrated here.

  When the elevator for the high-rise bank is performing a special operation, the control unit 21 of the group management control device 11b periodically calculates the number of people remaining in the dangerous floor (step S21). As described above, the number of people in each floor can be obtained from a camera image, a record of getting on / off, or a security system.

  Here, when the remaining number of people on the dangerous floor is larger than a preset number of people Pa (for example, 100 people) (No in step S32), the control unit 21 maintains the special operation as it is and is used for the high-rise bank. The destination floor of the elevator is the transit floor.

  On the other hand, when the remaining number of people in the dangerous floor is smaller than Pa (Yes in step S32), the control unit 21 determines whether or not the number is larger than a preset number of people Pb (for example, 50 people) ( Step S33). When the number is larger than the number of people Pb (No in step S33), the control unit 21 selects one of the plurality of units that are present as the elevator for the high-rise bank, and circulates between the transit floor and the evacuation floor. Is operated (shuttle operation) (step S35).

  If the number is less than the number of people Pb and not zero (No in step S34), the control unit 21 selects two of the plurality of units that are present as high-rise bank elevators, the transfer floor and the evacuation floor. Is operated in a circular manner (shuttle operation) (step S36).

  Furthermore, when the remaining number of dangerous floors becomes zero (Yes in step S34), the control unit 21 selects all elevators for the high-rise bank and makes a round trip between the transit floor and the evacuation floor. Is operated (shuttle operation) (step S37).

  In addition, when switching to such a shuttle operation, it is preferable to notify the current driving information to the car and the landing so that the occupants are not confused.

  FIG. 10 shows an example of a case where a high-rise bank elevator is shuttle-operated in a low-rise zone. In this example, a state is shown in which D of the elevators for high-rise banks, Unit D, Unit E, and Unit F, is shuttle-operating between 11F, which is the transfer floor, and 1F, which is the evacuation floor. .

  In this way, the special operation of the elevator for the high-rise bank has eased the mixed situation on the transfer floor by carrying the residents in the dangerous floor to the evacuation floor and then circulating between the evacuation floor and the evacuation floor The residents can be evacuated quickly.

  In addition, by deciding the number of laps between the transit floor and the evacuation floor according to the number of people remaining in the dangerous floor, the elevator for the high-rise bank is inadvertently left in the dangerous floor. Preventing switching to shuttle operation can alleviate the mixed situation on the transfer floor.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.

  In the fourth embodiment, it is assumed that there are at least two connecting floors with elevators in other banks in the same bank, and the special operation is performed by switching the connecting floors according to the congestion situation.

  FIG. 11 is a diagram showing a bank configuration of an elevator rescue operation system according to a fourth embodiment of the present invention, and shows a case where there are two transit floors for a high-rise bank elevator and a low-rise bank elevator.

  In this example, 11F is the transfer floor 1 and 8F is the transfer floor 2, and D, E and F, which are elevators for high-rise banks, can be stopped at the two transfer floors 1 and 2. is there.

  In addition, in a low-rise bank, it becomes a non-stop floor between 12F-20F, and cannot physically land on these floors. On the other hand, in a high-rise bank, it becomes a non-stop floor between 2F-10F except 8F, and it cannot physically land on these floors.

  FIG. 12 is a diagram showing another example of the bank configuration, which has three banks of a low layer, a middle layer, and a high layer. In this example, Unit A and Unit B operate the low-rise zone (1F to 8F) as the elevator for the low-rise bank, Unit C and Unit D operate the intermediate layer zone (8F to 14F) as the elevator for the intermediate layer, Unit F operates the high-rise zone (14F-20F), 1F, and 8F as a high-rise bank elevator.

  1F is a common floor for each elevator and is used as an evacuation floor when a fire breaks out. 8F is used as a transfer floor 2 for an elevator for a low-rise bank, an elevator for a mid-rise bank, and an elevator for a high-rise bank. 14F is used as a connecting floor 1 between the middle-rise elevator and the high-rise bank elevator.

  In the low-rise bank, the floors between 9F and 20F are non-stopping floors, and it is not possible to physically land on these floors. On the other hand, in the middle bank, between 2F-7F and 15F-20F are non-stop floors, and it is not possible to physically land on these floors. In a high-rise bank, it becomes a non-stop floor between 2F-13F except 8F, and it cannot physically land on these floors.

  Hereinafter, the operation processing in the fourth embodiment will be described using the bank configuration of FIG. 11 as an example. Note that the basic apparatus configuration is the same as that in FIG. 1, and therefore the description thereof is omitted here.

  FIG. 13: is a flowchart which shows the driving | operation process at the time of the fire outbreak of the rescue operation system of the elevator in 4th Embodiment. The processing shown in this flowchart is executed in each of the group management control device 11a for the low-level bank and the group management control device 11b for the high-level bank.

  In the following, it is assumed that a fire has occurred in the high-rise zone, and the process executed mainly on the group management control device 11b side for the high-rise bank will be described.

  Normally, elevators A, B, C, which are elevators for low-rise banks, and elevators D, E, F, which are elevators for high-rise banks, are individually operated in response to hall calls on each floor. Here, in the event of a fire in the high-rise zone, in order to efficiently transport a large number of people on the high-rise floors to a safe place, the high-rise bank elevator will change the transfer floor 1 or Special operation is performed with the transfer floor 2 as the destination floor.

  As shown in FIG. 13, when a fire occurs in a high-rise zone in a building, the fire detection device 12 detects a fire occurrence place (a floor where a fire has occurred), and the detection signal is a group management control device for a high-rise bank. 11b (step S40). Thereby, the control part 21 provided in the group management control apparatus 11 performs the following operation processes.

  That is, the control unit 21 includes the floor where the fire has occurred, and determines the floor above it as a dangerous floor (step S41). Then, the control unit 21 determines whether or not the dangerous floor is within the own bank response zone (step S42 (1)). In the case of a high-rise bank, since the dangerous floor is within the own bank response zone, the answer is Yes. In the case of a low-rise bank, No because the dangerous floor is outside the own bank response zone.

  Next, the control unit 21 determines whether or not there is a transit floor on the way from the dangerous floor to the first floor which is the evacuation floor (step S42 (2)). Here, in the case of a high-rise bank, since there is a transfer floor to a low-rise bank, it becomes Yes. However, even in a high-rise bank, if the building does not have a transfer floor to a low-rise bank, the answer is No.

  Here, if the answer is No in step S42 (1) or S42 (2), a normal evacuation operation is performed using the low-rise bank elevator and the high-rise bank elevator (step S43).

  In the normal evacuation operation, the low-rise bank elevator and the high-rise bank elevator are each operated toward the 1F evacuation floor. During the evacuation operation, the evacuation floor on the 1st floor is automatically registered, and the car call registration on other floors is prohibited. In addition, landing calls can be arbitrarily registered on each floor.

  On the other hand, if the answer is Yes in steps S42 (1) and S42 (2), the control unit 21 determines that the lap time of the elevator for the high-rise bank needs to be shortened, and the high-rise bank at the time of evacuation is determined. The destination floor of the elevator is changed from the preset evacuation floor to the transfer floor 1 and the special operation is executed.

  At that time, during the special operation, the residents are concentrated on the transfer floor 1, so it may take time to change to the elevator for the low-rise bank. Therefore, the control unit 21 calculates the waiting time for the transfer floor 1 (step S44). The waiting time can be obtained by counting the elapsed time from when the hall call is registered on the transit floor until the elevator for the low-rise bank responds. In the example of FIG. 11, 11F is the transfer floor 1, and the time until the A, B and C elevators, which are elevators for low-rise banks, respond to the 11F landing call is determined as a waiting time.

  If the waiting time is equal to or less than a preset time Tc (for example, 1 minute) (Yes in step S45), the destination floor is changed to the connecting floor 1 and the special operation is executed (step S46). As a condition for executing the special operation, as in the first embodiment, the time required for carrying all the residents in the dangerous floor to the first floor evacuation floor (rescue time) is obtained. Special operation may be performed when the rescueable time is longer than the predetermined time Ta (see steps S14 to S16 in FIG. 5).

  In the example of FIG. 11, the transfer floor 1 with the elevator for low-rise banks is 11F. Therefore, the elevators D, E, and F, which are elevators for the high-rise bank, are turned up at 11F and operated in a circular manner in the high-rise zone.

  During special operation, the 11th floor transit floor is automatically registered and car call registration on other floors is prohibited. For the hall call, only the dangerous floor may be registered, or each floor in the high-rise zone including the dangerous floor may be registered. If only dangerous floors can be registered for hall calls, people in the floor below the dangerous floor in the high-rise zone will use the stairs to go to the connecting floor, but after a predetermined time has elapsed. When the number of people in the dangerous floor has decreased to some extent, it may be returned to a state in which the hall calls on each floor can be registered.

  In addition, the control unit 21 notifies the car 15 and the landing 17 that the destination floor of the elevator for the high-rise bank has been changed to the transfer floor 1 (step S47). The notification method may be a message display or voice.

  Here, if the residents are concentrated on the transfer floor 1 due to the special operation and the waiting time becomes longer than the preset time Tc (Yes in Step S45), the control unit 21 changes the connection. It is determined that the floor 1 is congested, the presence or absence of the transfer floor 2 below the transfer floor 1 is checked, and if there is the transfer floor 2, the destination floor of the elevator for the high-rise bank is changed to the transfer floor 2.

  At that time, the control unit 21 calculates the waiting time at the transfer floor 2 and confirms the congestion state (step S48). When the waiting time at the transfer floor 2 is equal to or less than a preset time Td (for example, 1 minute) (No in step S49), the control unit 21 transfers the destination floor of the high-rise bank elevator to the transfer floor. 2 is changed (step S50). At this time, the control unit 21 notifies the current driving information to the car and the landing so that the resident is not confused (step S50).

  Thereafter, the special operation is executed with the destination floor of the elevator for the high-rise bank as the transfer floor 2. Even during the special operation, the control unit 21 calculates the waiting time at the connecting floor 2 and monitors the congestion state (step S49). And when waiting time in transfer floor 2 becomes longer than preset time Td (for example, 1 minute) (Yes of Step S49), control part 21 is what transit floor 2 is congested. Therefore, the high-rise bank elevator is not directly stopped at the transfer floor 2 but directly operated to 1F, which is an evacuation floor (step S52). At this time, the control unit 21 notifies the car and the hall of the current driving information so as not to confuse the resident (step S53).

  If the waiting time at transit floor 1 or transit floor 2 is resolved within a predetermined time during direct operation to the evacuation floor, the destination floor of the high-rise bank elevator is changed to transit floor 1 or transit floor 2. It may be returned to perform special operation.

  In this way, when there are at least two connecting floors with the elevator for the low-rise bank, switching to the other connecting floor according to the congestion status of one of the connecting floors, and performing special operation, it is located in the dangerous floor Can be evacuated efficiently.

  In addition, although the case where there are two transfer floors between the high-rise bank elevator and the low-rise bank elevator has been described here, the same applies to the case where there are two or more transfer floors. In this case, when there is more than one transit floor, it is the first decision to shorten the lap time of the high-rise bank elevator and bring the people on the dangerous floor to a safe place as soon as possible in the event of a fire. Among these, it is preferable to sequentially switch from the uppermost transfer floor to the lower transfer floor.

  The same applies to the case where the bank is divided into a low-layer bank, a middle-layer bank, and a high-layer bank as shown in FIG.

  That is, when a fire occurs, first, a special operation is performed in which the transit floor 1 (14F in this example) between the middle-rise elevator and the high-rise bank elevator is the target floor of the high-rise bank elevator. Then, when the waiting time of the transfer floor 1 exceeds a predetermined time, the special operation is performed by changing to the transfer floor 2 (8F in this example) between the low-rise bank elevator and the high-rise bank elevator. Furthermore, when the waiting time on the transfer floor 2 exceeds a predetermined time, operation control is performed such that the direct operation is performed to 1F, which is the evacuation floor.

  As described above, according to the present system, in a configuration in which a plurality of elevators are divided into banks on the high and low floors, when a fire occurs on the high floor, the destination floor of the high-rise bank elevator is connected to the low-rise bank elevator. By switching to the transfer floor and driving, it is possible to shorten the lap time of the elevator for the high-rise bank and efficiently carry the residents in the dangerous floor to a safe place as soon as possible.

  In each of the above embodiments, assuming a case where a fire has occurred on a higher floor, the method of performing a special operation by changing the destination floor of the elevator for the higher bank to the transfer floor with the elevator for the lower bank has been described. However, when there is a transfer floor (transfer floor 2) in the middle of the low-rise zone as in the example of FIG. 11, transfer may be performed even in the low-rise zone depending on the location of the fire.

  That is, for example, in the case of a fire at 10F in FIG. 11, the destination floor of the low-rise elevator (at least one of Unit A, Unit B, Unit C or all units) is transferred from the evacuation floor of 1F to 8F Change to floor 2 and execute special operation. Thereby, the lap time of the low-rise elevator can be shortened, and the residents in 11F above the fire occurrence floor can be evacuated via the transit floor 2 as soon as possible.

  Similarly, when there is a middle zone as in the example of FIG. 12, transfer may be performed in the middle zone depending on the location of the fire.

  That is, for example, in the event of a fire on 13F in Fig. 12, the target floor of the middle-tier elevator (one of C or D, or all) is changed from the 1F evacuation floor to the 8F transfer floor 2 And execute special operation. Thereby, the lap time of the middle-tier elevator can be shortened, and the residents in 14F above the fire occurrence floor can be evacuated via the transit floor 2 as soon as possible.

  Moreover, although said each embodiment demonstrated and assumed the rescue operation when a fire generate | occur | produced, this invention is applicable similarly when some disasters other than a fire generate | occur | produce in a building.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
