Description

  Embodiments described herein relate generally to an elevator evacuation operation system.

  Recently, there has been proposed an evacuation elevator that has a fire prevention zone and operates a car between a fire occurrence floor and an evacuation floor in the event of a fire. (For example, refer to Patent Document 1).

  However, if a fire breaks out in the building, the building occupants above the fire floor need to escape from the fire floor to the evacuation floor.

  However, the floor above the fire floor has a risk of fire spread, and the building residents on the upper floor have a high risk of being unable to evacuate.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment)
FIG. 1 is a diagram showing a schematic configuration of an elevator evacuation operation system according to an embodiment of the present invention. As shown in FIG. 1, the present system includes an elevator control device 10, an elevator car 11, a hall call button 12, a fire detection device 13, and a notification device 14.

  The elevator control device 10 controls the operation of the elevator such as registration of a car call and opening / closing of a door. The elevator control device 10 is configured by a computer. The “car call” is a call signal registered by operating a destination floor designation button provided in the car 11 and includes information on the destination floor.

  The car 11 moves up and down in the hoistway by driving a hoisting machine (not shown), and moves between the floors with passengers on it.

  The hall call button 12 is installed at the hall of each floor. By operating the hall call button 12, a hall call signal including information indicating the floor and destination direction of the hall is sent to the elevator control device 10. The “calling hall” is a call signal registered by operating the hall call button 12 installed at the hall on each floor, and includes information on the registered floor and the destination direction.

  The fire detection device 13 is installed on each floor of the building, detects the occurrence of a fire, and notifies the elevator control device 10 of the occurrence location.

  The notification device 14 notifies an evacuation warning or the like when the fire detection device 13 detects the occurrence of a fire.

  FIG. 2 is a diagram showing the configuration of the elevator car 11.

  A car door 15 is provided in front of the car 11 so as to be freely opened and closed. Next to the car door 15 is provided an operation panel 16 on which various operation buttons are arranged. The operation panel 16 is provided with a destination floor designation button 17 for a passenger to designate a destination floor, a door opening button 18, a door closing button 19, and the like.

  In the car 11, a display 20 for displaying a message and a speaker 21 for making a voice announcement are installed.

  FIG. 3 is a diagram showing a configuration of an elevator hall. A landing door 23 is provided at the elevator hall 22 so as to be freely opened and closed. The landing door 23 is opened and closed by engaging with the car door 15 when the car 11 is landed. A landing call button 24 is provided in the vicinity of the landing door 23. The hall call button 24 is an operation button for registering a hall call, and includes an upper direction designation button and a lower direction designation button for designating a destination direction. Apart from the hall call button 24, a hall call button 25 dedicated to wheelchair users is provided.

  An indicator 26 for displaying the current car position and the like is provided on the landing door 23. Further, an indicator 27 for displaying a message and a speaker 28 for making a voice announcement are installed in the vicinity of the landing door 23.

  Next, the operation of this system will be described.

  FIG. 4 is a diagram illustrating the movement of the elevator in the evacuation operation system according to the first embodiment.

  As shown in FIG. 4, it is assumed that a fire has occurred on the floor located above the evacuation floor which is the reference floor. Elevator operation services will be provided for floors above the evacuation floor and fire floor. In this case, in order to advance the evacuation of the residents in a safe and smooth manner, it is preferable to set a certain priority response floor and directly operate to the evacuation floor. The priority response will be described later.

  On the other hand, for the floors below the fire-breaking floor, the elevator operation service is suspended except for the evacuation floor. At that time, the floor 27 for which service is to be stopped is displayed on the indicator 27 installed at the landing that the elevator operation service such as “cannot be used” or “use evacuation stairs” cannot be received. .

  When fires occur on multiple floors, the elevator operation service is given the highest priority over the floors that frequently pass the fire floors in the route to the evacuation floor.

  Thus, when a fire breaks out, priority can be given to evacuating a user on a floor that is difficult to evacuate, thereby increasing the probability of evacuation.

  FIG. 5 is a flowchart showing the processing operation of the evacuation operation when a fire occurs in the first embodiment. Needless to say, this evacuation operation process is an example, and is not limited thereto. The processing shown in the flowchart is executed by incorporating a predetermined program into the elevator control device.

  When a fire occurs in the building, the fire detection floor is detected by the fire detection device 12, and the detection signal is given to the elevator control device 10 (step S501). As a result, the elevator control device 10 switches from the normal operation mode to the evacuation operation mode, and first cancels all currently registered hall calls in the DN direction (downward), so that the people in the building can move downward. It is prohibited to move to (step S502).

  And the elevator control apparatus 10 performs the following evacuation operation | movement, after making an elevator respond to a hall call and a car call of UP direction (upward direction) (step S503). Not only the DN direction but also the hall call in the UP direction may be canceled once.

  In the evacuation operation mode, the elevator control device 10 sets a floor (this is referred to as a priority response floor) that causes the elevator to respond preferentially based on the information on the fire occurrence floor detected by the fire detection device 12 ( Step S504).

  This priority response floor is a floor adjacent to the fire occurrence floor, and is basically set to the floor immediately above the fire occurrence floor. This is because the fire spreads upward, so if there is a resident on the floor directly above the place where the fire occurred, it must be evacuated with the highest priority.

  For example, assume that a fire has occurred on the 5th floor. In that case, 6F is set as the priority response floor. In addition, it is preferable that 5F which is a fire occurrence floor is excluded from a response object, and when a fire breaks out, it announces through the alerting device 14 so that it may evacuate quickly from the place to an evacuation floor.

  Here, the elevator control device 10 determines whether or not a hall call is generated on the priority response floor (step S505). If a hall call occurs on the priority response floor, that is, if there is a person on the 6th floor and the hall call buttons 24 and 25 installed on that floor are pressed (Yes in step S505), the elevator control device 10 causes the elevator to respond to the priority response floor 6F (step S506) and heads for 6F.

  In addition, it is preferable that the elevator control device 10 notifies the car 11 and the landing 22 that the evacuation operation is being performed (step S507). The notification method may be a message display or voice. Thereby, it can be relieved by informing the 6F residents that the elevator will respond.

  In addition, by performing such a message at the landing on each floor, it is possible to reassure the residents on other floors.

  When the elevator responds to 6F, which is the priority response floor, and the occupant gets in, the elevator control device 10 automatically registers the car call of 1F, which is the evacuation floor, and departs. In this case, registration of car calls on floors other than the evacuation floor is prohibited.

  The elevator control device 10 determines whether or not to depart in a state close to full (step S508). It is assumed that the “nearly full state” is about 80% of the rated load set for the car 11. The loaded load of the car 11 is detected by a load sensor (not shown), and it is determined from the detected loaded load whether the vehicle is almost full. If the state is almost full (Yes in step S508), the elevator control device 10 directly operates the elevator directly to the 1F that is the evacuation floor (step S509).

  On the other hand, if it is not nearly full, that is, if the elevator leaves with some margin (No in step S508), the elevator control device 10 counts and stores the number of departures (step S508). S510).

  When the stored number of departures reaches a preset number (for example, 5 times) as the priority response floor switching condition (Yes in step S511), the elevator control device 10 is in the current priority response floor. After determining that there is no building person and driving the elevator directly to 1F, which is the evacuation floor (step S512), the priority response floor is reset (step S513). In this case, one floor above the current priority response floor is reset as the priority response floor. That is, 7F is reset as the next priority response floor.

  When the priority response floor is reset, the elevator control device 10 determines whether or not the reset priority floor is “top floor + 1” (step S514). If it is not “top floor + 1” (No in step S514), the process returns to step S505, and the same evacuation operation is performed on the reset priority response floor. If the reset priority response floor is “top floor + 1” (Yes in step S514), the elevator control device 10 determines that there is no floor to respond to, and ends the evacuation operation.

  On the other hand, when there is no landing call on the priority response floor in step S505, the elevator control device 10 waits for a certain time (for example, 1 minute) (step S515). If there is no hall call during this time (Yes in step S515), the elevator control device 10 determines that there is no occupant on the floor and resets the priority response floor (step S513). If there is a hall call on the priority response floor without a certain time (No in step S515), the process proceeds to step S505.

  According to the system according to the first embodiment, since the elevator responds preferentially from the floor above the fire occurrence floor, the residents can evacuate quickly using the elevator.

  In addition, by switching the priority response floor at a predetermined timing, people in each floor can be efficiently transported to the evacuation floor.

(Modification of the first embodiment)
If the hall call above the fire floor is not detected for a predetermined time, the service is started for the floor where the elevator operation service has been stopped.

  In this case, it can be determined that the evacuation of the floor above the fire occurrence floor has been completed. The predetermined time is detected by, for example, determining whether or not a hall call from the upper floor is detected for 5 minutes or more by providing a timer in the elevator control device. The timer count is preferably started when the elevator control device receives a fire occurrence signal.

(Second Embodiment)
Next, a second embodiment will be described. Depending on the location of the building, there are buildings with many underground floors. For example, in a building adjacent to the cliff, if the ground floor is an evacuation floor from the higher floor such as the 6th floor, 7th floor, etc., or the adjacent floor is connected to the higher floor and the contact floor is also an evacuation floor is there.

  FIG. 6 is a diagram illustrating the movement of the elevator of the evacuation operation system according to the second embodiment. In the second embodiment, the evacuation floor is located in the middle of the building, and the operation service system is used when a fire occurs on the floor below the evacuation floor.

  When a fire is detected, if the car is located above the fire floor, stop driving on the fire floor and floor below the fire floor, Only the upper floor provides elevator operation services.

  If the car is located below the fire floor when a fire is detected, the car is first operated normally in response to a call from the floor above the fire floor. After the car moves to the floor above the fire floor, the operation on the floor below the fire floor is stopped, and the elevator operation service is performed only on the floor above the fire floor.

  Thus, when a fire breaks out, priority can be given to evacuating a user on a floor that is difficult to evacuate, thereby increasing the probability of evacuation.

(Modification of the second embodiment)
If the hall call above the fire floor is not detected for a predetermined time, the service is started for the floor where the elevator operation service has been stopped.

  As described above, according to the present embodiment, it is possible to preferentially evacuate and evacuate residents above the fire floor.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
