DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
1 to 5 are diagrams showing an embodiment of the first to fourth inventions of the present invention. FIG. 1 is an overall configuration diagram, FIG. 2 is a vertical sectional view of a hoistway, FIG. 3 is an evacuation operation flowchart, and FIG. Is an operation flowchart after operation stop, and FIG. 5 is a flowchart when the evacuation floor does not arrive.
[0008]
In FIG. 1, the state of the fire detector 1 is detected by the fire detection means 2. In addition, the state of the fire shutter installed for each floor is detected by the fire shutter detector 3, and the fire shutter detector 3 detects which floor the fire shutter detector 3 is operating. The car operation control means 5 operates the car from the car position detected by the output of the fire detecting means 2 and the fire shutter detecting means 4 and the car position detecting means 6 to the floor where the fire shutter is not down.
[0009]
In addition, when the car is evacuated and the shutter of that floor is released, or when it cannot reach the evacuation floor due to some abnormality and stops at the floor where the shutter is lowered, the passenger detection means 7 has passengers in the car Is detected, the car operation control means 5 travels to the floor where the shutter is not down. The notification control means 8 displays or announces to the passenger.
[0010]
In FIG. 2, the relationship between the car 11 and the floor is shown. The first evacuation floor is the second floor 2F, and the second evacuation floor is the third floor 3F. In this example, it is assumed that the fire shutter 12 on the first floor 1F is down. The car 11 is traveling toward the second floor 2F, which is the first evacuation floor.
[0011]
Next, the operation of this embodiment will be described with reference to FIGS.
(1) Evacuation floor operation in case of fire (Figure 3)
In step S1, it is determined whether the fire detection means 2 has detected the operation of the fire detector 1. If the fire detector 1 is not operating, the elevator operation is continued in step S2. If the fire detector 1 is operating, in step S3, the fire shutter detection means 4 determines whether the fire shutter on the first evacuation floor 2F is down.
[0012]
If the fire shutter on the first evacuation floor 2F has not been lowered, the process proceeds to step S4, and the car operation control means 5 causes the car 11 to travel to the first evacuation floor 2F. If the fire shutter on the first evacuation floor 2F is down, the process proceeds to step S5, and the car 11 travels to the second evacuation floor 3F. Thereafter, the door of the car 11 is opened in step S6, and the door is closed after a predetermined time has elapsed in step S7. In step S8, it is determined whether the door opening button has been pressed in the car 11, that is, whether there is a passenger. If the door opening button is pressed, the process returns to step S6.
[0013]
Here, steps S <b> 1 to S <b> 9 constitute the car operation control means 5.
In this way, when a fire occurs in a building with a fire shutter, the car 11 is caused to travel to an evacuation floor where the fire shutter is not lowered, so that passengers can be evacuated with certainty.
[0014]
(2) Operation after shutdown (Fig. 4)
In step S11, the car 11 is suspended. In step S12, it is determined whether the fire shutter of the floor where the car 11 is stopped is down. If the fire shutter is down, the process proceeds to step S13, and it is determined whether the boarding detection means 7 has detected that there are passengers in the car 11. As a means for this determination, a car load, presence / absence of door opening button operation, installation of a dedicated button, etc. can be considered, but there is no particular limitation. If it is determined that there are no passengers, the process returns to step S12. If it is determined that there is a passenger, the process proceeds to step S14, and the passenger is notified by an announcement, a display, and the like that the car 11 is traveling to a floor where the fire shutter is not down.
[0015]
In step S15, it is determined whether the fire shutter detector 3 is installed on each floor other than the first evacuation floor 2F. When the fire shutter detector 3 is installed on each floor, the process proceeds to step S16, the car 11 is run to the floor where the fire shutter is not down, and the operation is stopped in step S19. When the fire shutter detector 3 is not installed except for the first evacuation floor 2F, the process proceeds to step S17, and the car 11 travels to the nearest floor. Thereafter, in step S18, it is determined whether there are passengers in the car 11.
[0016]
If it is determined that there are passengers in the car 11, the process returns to step S <b> 17 to continue traveling on the nearest floor until the passengers are no longer in the car 11. If there are no passengers, the operation is suspended in step S19.
Here, steps S11 to S13 constitute re-running condition detection means, step S14 constitutes the alarm control means 8, step S15 constitutes a fire shutter detector presence / absence detection means, and steps S16 to S19 constitute re-running instruction means. Yes.
In this way, even when a fire occurs in a building with a fire shutter, and the car 11 arrives at the evacuation floor and the operation is suspended, even if the fire shutter is released, the car 11 re-runs and the fire shutter is installed. Since it stops on the floor where it does not get off, it is possible to evacuate passengers reliably.
[0017]
(3) Operation when the evacuation floor does not arrive (Figure 5)
The car 11 is moved to the first or second evacuation floor 2F or 3F by the operation of FIG. 3, but the car cannot reach the first or second evacuation floor 2F or 3F due to some abnormality, and stops on the middle floor. Suppose that the operation is suspended.
In step S21, the operation is suspended. In step S22, it is determined whether there are passengers in the car 11. If it is determined that there are no passengers, operation suspension is continued in step S23. If it is determined that there are passengers, the process proceeds to step S24 to determine whether the fire shutter on the floor where the car 11 is stopped is down.
[0018]
If it is determined that the fire shutter is down, the process proceeds to step S25, where it is determined whether or not the elevator can travel, and if it can travel, the process proceeds to step S26. In step S26, it is determined whether the fire prevention shutter of the first evacuation floor 2F is down. If not, the car 11 is driven to the first evacuation floor 2F in step S27. The car 11 is made to travel to the evacuation floor 3F, and the operation is suspended in step S29.
[0019]
Here, steps S22 and S24 constitute re-running condition detection means, and steps S25 to S28 constitute re-running command means.
In this way, a fire broke out in a building with a fire shutter, and the car 11 traveled to the evacuation floor, but even if the car 11 could not reach the evacuation floor due to some abnormality, the car 11 re-runs and the fire shutter was installed. Since it stops on the floor where it does not get off, it is possible to evacuate passengers reliably.
[0020]
【The invention's effect】
As described above, in the present invention, when a fire is detected, since the elevator car is run to a predetermined evacuation floor where it is detected that the fire shutter is not down, the operation is suspended on that floor. When a fire breaks out in a building with a shutter, passengers can be evacuated reliably.
