Description

  The present invention relates to a method for operating a double deck elevator, and more particularly to a method for evacuating a double deck elevator when a fire occurs.

  In recent years, due to reasons such as an increase in high-rise and large buildings and the social advancement of physically disabled people, it has been attempted to use elevators as a quick evacuation method or as an evacuation method for people who cannot use emergency stairs in the event of a disaster such as a fire. There is a request to do.

  Therefore, the operation of the fire alarm provided on the elevator stop floor is detected, and during the period from when the operation is detected until the predetermined operation control condition is satisfied, the elevator is only on the fire alarm operation floor and the predetermined evacuation floor. An elevator control operation system has been proposed in which the operation is controlled so that it can be stopped and the elevator is returned to the evacuation floor and stopped after a predetermined operating condition is satisfied (see, for example, Patent Document 1).

  In addition, there has been proposed a double deck elevator that is provided with an interval adjustment mechanism for the upper car and the lower car, and further provided with an auxiliary power feeding device so that the elevator can be landed even when the elevator is not allowed to self-run during a power failure (for example, a patent) Reference 2).

However, in the conventional elevator control operation system, the elevator is operated and controlled only at the fire alarm operating floor and the evacuation floor, so that the number of people traveling from the fire alarm operating floor to the evacuation floor per time There are few evacuation movements of people on floors other than fire alarm operating floors, and in the event of a fire, people in the building as well as fire alarm operating floors are efficiently evacuated There was a problem that it was not possible.
Moreover, in the conventional double deck elevator, there is no description or suggestion about using it for evacuation in the event of a fire.

  In view of this situation, the present applicant has found that a double deck elevator is suitable for moving a large number of passengers to a specific floor at a time, and is effective in the event of a disaster that requires many people to evacuate quickly. In the event of a fire, the evacuation priority is the highest on the floor where the fire occurred, then it goes down to the upper floor of the fire floor, and further down to the lower floor of the fire floor, The present invention has been invented from the viewpoint that it is important to evacuate people based on evacuation priority.

  This invention controls the operation of a double deck elevator suitable for moving many passengers to a specific floor at a time in the event of a fire in consideration of the evacuation priority of each floor in the building. An object of the present invention is to obtain an evacuation operation method for a double deck elevator that can efficiently evacuate a vehicle.

  In the evacuation operation method of the double deck elevator according to the present invention, in the event of a fire, the lower cab is allocated to the evacuation target floor and a person gets on board. Evacuation operation that repeats the operation mode in which the upper cab is dispatched to the floor to be evacuated and people are picked up and move to the evacuation floor until a predetermined condition is satisfied. This is done by moving the floor from the fire floor to the upper floor sequentially.

  According to the present invention, the lower cab is first assigned to the fire floor and the upper cab is assigned to the fire floor when a person cannot get into the lower cab. Evacuation from high fire floor to evacuation floor can be given top priority. In addition, evacuation from the fire floor to the evacuation floor will be performed only by descending operation without going up the cab, and efficient evacuation from the fire floor with the highest evacuation priority to the evacuation floor will be performed. be able to. Furthermore, since the floors subject to evacuation are shifted from the fire floor to the higher floors one by one and the evacuation operation is performed sequentially, the evacuation from the floors subject to evacuation to the evacuation floors is performed in the order of higher evacuation priority floors. Efficient evacuation.

When it is determined that no fire has occurred, the elevator is operated in the normal operation mode (step 109). When it is determined that a fire has occurred, the monitoring control device 10 switches the elevator operation mode from the normal operation mode to the evacuation operation mode. The evacuation floor is set to a safe floor below the fire occurrence floor.

Then, the process proceeds to step 101, where it is determined from the detection output of the human detector 9 whether or not there is a person on the fire occurrence floor. If it is determined that there is a person on the floor where the fire occurred, the car frame 1 is moved up and down, the lower car room 3 is assigned to the fire floor and the door is opened (step 102), and the person moves down from the fire floor. Get in the room 3 (step 103). Next, the process proceeds to step 104, where it is determined from the detection output of the human detector 9 whether or not a person remains on the fire floor. When it is determined that there are people remaining on the fire floor, the car frame 1 is lowered and the upper car room 2 is dispatched and opened on the fire floor (step 105). Get in the upper cab 2 (step 106).
Next, the car frame 1 is lowered, the lower car room 3 is moved to the evacuation floor and the door is opened, and the person is evacuated to the evacuation floor (step 107). Further, the car frame 1 is lowered, the upper car room 2 is moved to the evacuation floor and the door is opened, the person is evacuated to the evacuation floor (step 108), and the process returns to step 101.
If it is determined in step 104 that no people remain on the floor where the fire occurred, the process moves to step 107, and the lower room 3 is moved to the evacuation floor and opened.
When this procedure is repeated and it is determined in step 101 that no people remain on the fire floor, that is, when a predetermined condition is satisfied, the evacuation operation from the fire floor to the evacuation floor as the evacuation target floor ends. Is done.

  When the evacuation operation from the fire occurrence floor to the evacuation floor is completed, this evacuation operation mode is implemented with the evacuation target floor as the first floor above the fire occurrence floor, and from the first floor above the fire occurrence floor to the evacuation floor. Perform evacuation operation. In this way, the evacuation target floor is sequentially shifted from the fire occurrence floor to the higher floor one floor at a time, and this evacuation operation mode is carried out. At this time, the “fire occurrence floor” in the flowchart of FIG. 2 is the “evacuation target floor” such as the first floor above the fire occurrence floor.

As described above, according to the first embodiment, the lower cab 3 is first allocated to the fire occurrence floor, and the upper cab 2 is allocated to the fire occurrence floor when a person cannot get into the lower cab 3. Therefore, evacuation from the fire occurrence floor having the highest evacuation priority to the evacuation floor can be performed with the highest priority. Furthermore, evacuation from the fire floor to the evacuation floor will be carried out only by descending operation without raising the car frame 1, and efficient evacuation from the fire occurrence floor with the highest evacuation priority to the evacuation floor will be achieved. It can be carried out.
In addition, the evacuation target floor is shifted to the higher floor one by one from the floor where the fire occurred, and the evacuation operation is performed, so the evacuation from the evacuation target floor to the evacuation floor is performed in the order of the evacuation priority floor. Efficient evacuation.

First, the monitoring control device 10 monitors the detection output of the fire alarm 8 and determines whether or not a fire has occurred (step 200). When it is determined that no fire has occurred, the elevator is operated in the normal operation mode (step 206). When it is determined that a fire has occurred, the monitoring control device 10 switches the elevator operation mode from the normal operation mode to the evacuation operation mode. The evacuation floor is set to a safe floor below the fire occurrence floor.

And it moves to step 201 and it is judged from the detection output of the human detector 9 whether or not there is a person on the fire occurrence floor. When it is determined that there is a person on the fire floor, the car frame 1 is moved up and down, the lower car room 3 is assigned to the fire floor and the door is opened, and the upper car room 2 is located on the first floor above the fire floor. A car is allocated to the floor and the door is opened (step 202), and a person gets into the lower car room 3 and the upper car room 2 from the upper floor of the fire occurrence floor and the first floor of the fire occurrence floor (step 203). Next, the car frame 1 is lowered, the lower car room 3 is moved to the evacuation floor and the door is opened, and the person is evacuated to the evacuation floor (step 204). Further, the car frame 1 is lowered, the upper car room 2 is moved to the evacuation floor and the door is opened, the person is evacuated to the evacuation floor (step 205), and the process returns to step 201.
When this procedure is repeated and it is determined in step 201 that there are no people remaining on the fire floor, that is, when a predetermined condition is satisfied, the evacuation operation from the fire floor to the evacuation floor as the evacuation target floor ends. Is done.

  Then, when the evacuation operation from the fire occurrence floor to the evacuation floor is completed, this evacuation operation mode is implemented with the evacuation target floor as the first floor above the fire occurrence floor, and from the first floor above the fire occurrence floor to the evacuation floor Perform evacuation operation. At this time, if the evacuation from the first floor above the fire occurrence floor to the evacuation floor has been completed, the evacuation operation mode is implemented with the evacuation target floor as the second floor above the fire occurrence floor. In this manner, the evacuation target floor is sequentially shifted from the fire occurrence floor to the higher floor one floor at a time, and this evacuation operation mode is carried out. At this time, the “fire occurrence floor” in the flowchart of FIG. 3 is the “evacuation target floor” such as the first floor above the fire occurrence floor.

As described above, in the second embodiment, the lower cab 3 is first assigned to the fire occurrence floor, and the upper cab 2 is assigned to the first floor above the fire occurrence floor. The evacuation from the fire occurrence floor having the highest evacuation priority and the upper floor of the fire occurrence floor having the second highest evacuation priority to the evacuation floor can be performed with the highest priority. Furthermore, the evacuation from the fire floor to the evacuation floor will be carried out only by the descending operation without raising the car frame 1, and the evacuation from the fire occurrence floor having the highest evacuation priority to the evacuation floor is efficiently performed. It can be carried out.
In addition, the evacuation target floor is shifted to the higher floor one by one from the floor where the fire occurred, and the evacuation operation is performed, so the evacuation from the evacuation target floor to the evacuation floor is performed in the order of the evacuation priority floor. Efficient evacuation.
In addition, since the upper car room 2 and the lower car room 3 are boarded at the same time, evacuation can be performed efficiently and quickly.

Embodiment 3 FIG.
FIG. 4 is a flowchart for explaining an evacuation operation operation in a double deck elevator according to Embodiment 3 of the present invention. The configuration of the double deck elevator is the same as that of the first embodiment, and the description thereof is omitted.

Next, the evacuation operation method of the double deck elevator will be described with reference to FIG. In FIG. 4, step 300 and the like are shown as S300 and the like for convenience.
First, the monitoring control device 10 monitors the detection output of the fire alarm 8 and determines whether or not a fire has occurred (step 300). If it is determined that no fire has occurred, the elevator is operated in the normal operation mode (step 309). When it is determined that a fire has occurred, the monitoring control device 10 switches the elevator operation mode from the normal operation mode to the evacuation operation mode. The evacuation floor is set to a safe floor below the fire occurrence floor.

And it moves to step 301 and it is judged from the detection output of the human detector 9 whether or not there is a person on the fire occurrence floor. When it is determined that there is a person on the floor where the fire occurred, the car frame 1 is moved up and down, the lower car room 3 is assigned to the fire floor and the door is opened (step 302), and the person moves from the fire floor to the lower car. Get in the room 3 (step 303). At this time, the upper cab 2 is in a door closing standby state. Next, the process proceeds to step 304, and it is determined from the detection output of the person detector 9 whether or not a person remains on the fire occurrence floor. When it is determined that there are people remaining on the fire floor, the car frame 1 is lowered, the upper car room 2 is assigned to the fire floor and the door is opened (step 305), and the person starts from the fire floor. Get in the upper cab 2 (step 306).
Next, the car frame 1 is lowered, the lower car room 3 is moved to the evacuation floor and the door is opened, and the person is evacuated to the evacuation floor (step 307). Further, the car frame 1 is lowered, the upper car room 2 is moved to the evacuation floor and the door is opened, the person is evacuated to the evacuation floor (step 308), and the process returns to step 301.

If it is determined in step 304 that there is no person remaining on the fire-occurring floor, the process proceeds to step 310, where the upper room 2 is dispatched / opened to the first floor above the fire-occurring floor. Then, a person gets into the upper cab 2 from the upper floor of the first floor of the fire occurrence floor (step 311). Next, the car frame 1 is lowered, the lower car room 3 is moved to the evacuation floor and the door is opened, and the person is evacuated to the evacuation floor (step 312). Further, the car frame 1 is lowered, the upper car room 2 is moved to the evacuation floor and the door is opened, the person is evacuated to the evacuation floor (step 313), and the process proceeds to step 314.
When this procedure is repeated and it is determined in step 301 that there are no people remaining on the fire floor, that is, when a predetermined condition is satisfied, the evacuation operation from the fire floor to the evacuation floor as the evacuation target floor ends. Is done.

Next, in step 314, it is determined from the detection output of the person detector 9 whether or not there is a person on the upper floor of the first floor of the fire occurrence floor. If it is determined that there is a person on the first floor above the fire occurrence floor, the process proceeds to step 315, and the evacuation operation is performed with the floor to be evacuated as the first floor above the fire occurrence floor. The evacuation operation from the first floor above the fire occurrence floor to the evacuation floor in steps 314 and 315 is performed in the same manner as in steps 301 to 313.
Next, when it is determined in step 314 that there is no person on the first floor above the fire occurrence floor, the evacuation target floor is shifted to the second floor above the fire occurrence floor and the evacuation operation is performed.

  In this way, the evacuation target floor is sequentially shifted from the fire occurrence floor to a higher floor one by one, and this evacuation operation mode is carried out. In step 316, if there is a person on the N floor above the fire occurrence floor, If it judges, it will move to step 317 and will perform evacuation operation by making the floor to be evacuated into the upper floor of the Nth floor of the fire occurrence floor. The evacuation operation from the upper floor of the Nth floor of the fire occurrence floor to the evacuation floor in steps 316 and 317 is executed in the same manner as in steps 301 to 313. If it is determined in step 316 that there is no person on the upper floor of the Nth floor of the fire occurrence floor, the process moves to Step 318, and the evacuation operation is performed with the floor to be evacuated as the upper floor of the fire occurrence floor (N + 1) floor. The evacuation operation from the upper floor (N + 1) of the fire occurrence floor to the evacuation floor in step 318 is executed in the same manner as in steps 301 to 308. However, since the upper floor of the (N + 1) floor of the fire occurrence floor is the top floor, if it is determined in step 304 that there is no person remaining on the upper floor of the (N + 1) floor of the fire occurrence floor, the evacuation operation is performed. Ends.

Thus, according to the third embodiment, the lower cab 3 is first dispatched to the fire occurrence floor, and the upper cab 2 is kept waiting for door closing so that a person cannot get into the lower cab 3. In this case, since the upper cab 2 is arranged on the fire occurrence floor, evacuation from the fire occurrence floor having the highest evacuation priority to the evacuation floor can be performed with the highest priority. Furthermore, evacuation from the fire floor to the evacuation floor will be carried out only by descending operation without raising the car frame 1, and efficient evacuation from the fire occurrence floor with the highest evacuation priority to the evacuation floor will be achieved. It can be carried out.
In addition, the evacuation target floor is shifted to the higher floor one by one from the floor where the fire occurred, and the evacuation operation is performed, so the evacuation from the evacuation target floor to the evacuation floor is performed in the order of the evacuation priority floor. Efficient evacuation.
In addition, when a person gets into the lower car room 3, the upper car room 2 that is waiting for door closing is arranged on the upper floor of the first floor so that people on the upper floor of the first floor can get on. Evacuation of floors with high priority for evacuation is prioritized, and more rapid and accurate evacuation can be realized.

In the first to third embodiments, the evacuation floor is described as being set as one floor, but the evacuation floor may be set as two adjacent floors. In this case, when the person is evacuated from the floor to be evacuated, the upper cab 2 and the lower cab 3 may be simultaneously landed on the two evacuation floors, and the evacuation to the evacuation floor is performed more efficiently. .
Moreover, in the said Embodiment 1-3, when it is judged that there is no person remaining in the platform of the evacuation target floor based on the detection output of the human detector 9, the evacuation target floor is determined as satisfying a predetermined condition. Although it is described that the evacuation operation is performed by moving to the upper floor of the first floor, the predetermined condition is not limited to this. For example, the number of movements from the evacuation target floor to the evacuation floor, the evacuation operation time, etc. Good.

Embodiment 4 FIG.
FIG. 5 is a block diagram schematically showing a double deck elevator according to Embodiment 4 of the present invention.
In FIG. 5, the motor 11 is arranged between the upper car room 2 and the lower car room 3 as the car room interval adjusting mechanism. The motor 11 is operated by the monitoring control device 10 and is configured to be able to adjust the interval between the upper car room 2 and the lower car room 3.
Other configurations are the same as those in the first embodiment.

When the evacuation operation method according to the second and third embodiments is performed in a building with different floors, the interval between the upper cab 2 and the lower cab 3 is the landing interval between the evacuation target floor and the first floor upper floor. The lower cab 3 is dispatched to the evacuation target floor, a person is boarded, the car frame 1 is raised and lowered, and the upper cab 2 is dispatched to the first floor above the evacuation target floor. Will be on board.
However, if the double deck elevator according to the fourth embodiment is installed, the monitoring and control device 10 operates the motor 11, and the interval between the upper car room 2 and the lower car room 3 is set to the evacuation target floor and the upper floor of the first floor. Since it can be adjusted to the landing interval with the floor, the upper car room 2 is dispatched to the upper floor of the first floor of the evacuation target floor with the lower car room 3 being dispatched to the evacuation target floor without raising or lowering the car frame 1 Can be evacuated more quickly.
In addition, even when the distance between the upper car room 2 and the lower car room 3 is different from the landing distance between two adjacent evacuation floors, there are two distances between the upper car room 2 and the lower car room 3. By adjusting to the landing interval of the evacuation floor, two upper cab rooms 2 and three lower cab rooms 3 can be landed at the same time on the evacuation floor, so that more rapid evacuation can be realized.

  In the fourth embodiment, the motor 11 is used to adjust the distance between the upper cab 2 and the lower cab 3, but the cab spacing adjustment mechanism is limited to the motor 11. Instead, it is sufficient if the distance between the upper cab 2 and the lower cab 3 can be adjusted.
