In addition, the fire occurrence floor storage means 69 stores fire occurrence floor information indicating a floor where a fire has occurred and the use of the car 8 has become difficult. The evacuation floor priority storage unit 70 stores the evacuation floor priority information shown in FIG. 3 .

When a fire in the building is detected by the fire detector 29, the operation control unit 61 uses the information detected by the car load detection unit 66a, the car image detection unit 66b, and the hall control detection unit 64, and The information stored in the fire occurrence floor storage means 69 and the evacuation floor priority order storage means 70 is used to perform operation control at the time of fire occurrence (rescue operation control). Hereinafter, operation control at the time of fire occurrence by the operation control unit 61 will be described.

The operation control means 61 puts the boarding point of the fire occurrence floor into a use prohibition state. Specifically, the operation control unit 61 makes the boarding point broadcasting device 25 and the boarding point display device 27 of the floor where the fire occurs report that a fire is breaking out and that the boarding point becomes prohibited from use, and displays the position of the car 8. The indicator (not shown) of the fire is turned off, and the call registration from the fire-occurring floor is invalidated. In addition, the operation control unit 61 notifies the hall announcement device 25 and the hall display device 27 of the non-fire-occurring floor that the rescue operation is in progress. Furthermore, the announcement device 35 in the car and the display device 36 in the car are made to report that the rescue operation is in progress.

Then, the operation control unit 61 selects the user's evacuation destination from the first to third evacuation floors and non-evacuation floors based on the fire occurrence position and the evacuation floor priority order information. Specifically, the operation control unit 61 sequentially determines whether a fire is breaking out on the first to third evacuation floors, and when it is determined that at least one of the first to third evacuation floors is not on fire, the priority is higher. And the 1st to 3rd evacuation floors where no fire has occurred are set as evacuation destinations.

And the operation control unit 61 selectively switches the car 8 directly to the evacuation floor according to the boarding situation of the user in the car 8 detected by the car situation detection unit 66, or according to the information from the non-fire outbreak floor. Car 8 is allocated for call registration.

Specifically, the operation control means 61 determines the presence or absence of a user in the car 8 based on the boarding state of the user in the car 8 detected by the car state detection means 66 . In addition, when it is determined that there is no one in the car 8, the operation control unit 61 preferentially allocates the car 8 based on a call registration from a non-fire-occurring floor farther from the specified evacuation floor. Moreover, when both the load detection means 66a in a car and the image detection means 66b in a car do not detect a user, the operation control means 61 determines that there is no user in the car 8 .

In addition, when it is determined that there is no user in the car 8, the operation control unit 61 determines that there is no user in the car 8 based on the boarding status of the user in the car 8 detected by the car status detection unit 66. Is there room for the user to board the vehicle? In addition, when it is determined that there is room in the car 8 for the user to board, the operation control unit 61 assigns the car 8 based on a call registration from a non-fire-occurring floor on the way to the evacuation floor. That is, the operation control means 61 makes the car 8 travel to the evacuation floor while sequentially stopping at non-fire-occurrence floors on the way to the evacuation floor. And, when it is determined that the car 8 is full, the operation control unit 61 causes the car 8 to go directly to the evacuation floor. In addition, when at least one of the car load detection means 66a and the car image detection means 66b detects a user, the operation control means 61 determines that a user exists in the car 8 .

And, when it is desired to return the car 8 to the evacuation floor, if a fire is breaking out on all the 1st to 3rd evacuation floors, the operation control unit 61 performs a rescue operation for making the fire extinguishing operation easier. Actions. Specifically, the operation control unit 61 returns the car 8 to a lower non-evacuation floor where no fire has occurred, and makes the car 8 stand by on the non-evacuation floor with the doors closed. That is, the operation control unit 61 returns the car 8 to a floor where no fire has occurred, and restricts the output of the door opening command from the door switch control unit 60 to the car door control device 34 . In addition, a hall door device (not shown) with high smoke-proof/fire-proof performance is arranged at the hall.

Next, the operation/operation method will be described. FIG. 5 is a flowchart showing the operation control operation performed by the operation control unit 61 in FIG. 4 . In the drawing, first, it is determined whether a fire outbreak signal from the fire detector 29 is detected (step S1), and if no fire outbreak signal is detected, normal operation (service) is continued (step S2).

On the other hand, when a fire outbreak signal is detected, the boarding point of a fire outbreak floor is made into a use-prohibited state (step S3). Specifically, the call registration from this floor is invalidated, and the indicators arranged on this floor are extinguished, and the hall announcement device 25 and the hall display device 27 on the floor where the fire occurs are notified that a fire is taking place and that a fire is taking place. Information that the landing has become prohibited. At the same time, broadcast information and display information are output to the boarding point broadcasting device 25 and the boarding point display device 27 of the non-fire-occurring floor, and the situation in the rescue operation is reported by these boarding point broadcasting devices 25 and the boarding point display device 27 ( Step S4).

Next, the evacuation destination is determined based on the occurrence of the fire and the evacuation floor priority order information. Specifically, first, it is judged whether or not a fire is breaking out on the first evacuation floor (step S5), and if not, the evacuation destination is specified as the first evacuation floor (step S6). On the other hand, if a fire is breaking out on the first evacuation floor, then it is determined whether a fire is breaking out on the second evacuation floor (step S7), and if there is no fire on the second evacuation floor, the evacuation destination It is determined as the 2nd refuge floor (step S8), and under the situation that a fire is breaking out in the 2nd refuge floor, then judge whether a fire is breaking out in the 3rd refuge floor (step S9), if in the 3rd refuge floor If there is no fire, the evacuation destination is determined as the third evacuation floor (step S10).

When the evacuation destination is determined, it is determined whether there is a user in the car 8 according to the boarding situation detected by the car situation detection unit 66 (step S11), and when it is determined that there is no one in the car 8, priority The car 8 is allocated based on the call registration from the floor farther from the evacuation destination (step S12).

On the other hand, when it is determined that there is a user in the car 8 after the evacuation destination is determined, and when it is determined that there is a user in the car 8 after the car 8 is allocated to a non-fire-occurring floor, Broadcast information and display information are output to the broadcasting device 35 in the car and the display device 36 in the car, and the situation in the rescue operation is notified in the car 8 by the broadcasting device 35 in the car and the display device 36 in the car ( Step S13).

Next, according to the boarding situation detected by the car situation detection unit 66, it is determined whether there is room for the user to board in the car 8 (step S14), if it is determined that there is a user in the car 8 Can also get on the room, then according to the call registration from the non-fire occurrence floor on the way to the determined evacuation destination, the car 8 is allocated (step S15), if it is determined that it is a full state in the car 8, then the car The car 8 goes straight to the evacuation destination (step S16). Then, when the car 8 returns to the first to third evacuation floors (step S17), it is determined again whether or not a fire outbreak signal has been detected.

On the other hand, when it is determined that an evacuation destination is to be determined, if it is determined that fire is occurring on all the evacuation floors of the first to third evacuation floors, an operation is performed to facilitate the rescue operation after the fire extinguishing operation is completed. . That is, broadcast information and display information are output to the broadcasting device 35 in the car and the display device 36 in the car, and by these broadcasting devices 35 in the car and the display device 36 in the car, the situation in the rescue operation is notified (step S18 ), and report such as "please wait a moment" waiting machine instruction information (step S19) in the car 8. At the same time, make car 8 get back to the lowermost non-refuge floor (step S20) in the non-refuge floors that do not break out of fire, and make car 8 close the door on this non-refuge floor standby (step S21).

In such an elevator control device 16, when a fire breaks out in a building, the operation control unit 61 selectively switches the operation mode according to the riding status of the users in the car 8 detected by the car status detection unit 66. Since the car 8 is assigned to the call registration from the non-fire-occurrence floor, or the car 8 is directly directed to the evacuation floor, more users can use the car 8 to move to the evacuation floor, and the rescue efficiency of users can be further improved.

And, when a fire breaks out in the building, the operation control unit 61 determines whether there is a user in the car 8 according to the riding situation of the user in the car 8 detected by the car state detection unit 66. If it is determined that there is room for the user to board in the car 8, the car 8 is allocated according to the call registration from a non-fire-occurring floor on the way to the evacuation floor. When the car 8 is full, the car 8 goes directly to the evacuation floor, so the operating efficiency of the car 8 during the rescue operation can be improved, and the rescue efficiency of the user can be further improved.

Furthermore, when a fire broke out in the building, the operation control unit 61 judged the presence or absence of users in the car 8 based on the riding situation of the users in the car 8 detected by the car state detection unit 66, if If there is no one in the car 8, the car 8 will be allocated in response to the call registration from the non-fire floor farther from the evacuation floor, so it can be considered that the use of floors that are more difficult to move outside the building can be given priority for rescue. Or, the user's rescue efficiency can be further improved.

And, when wanting to make the car 8 return to the evacuation floor, the operation control unit 61 determines the evacuation floor according to the pre-registered evacuation floor priority information and the occurrence position of the fire, so the evacuation destination can be changed according to the development of the fire. , and the user can be moved to a non-fire-occurring floor, and the rescue efficiency of the user can be further improved.

And, when wanting to make the car 8 return to the evacuation floor, under the situation that all the evacuation floors are on fire, the operation control unit 61 makes the car 8 return to the non-refuge floor that is further below and does not have a fire, and makes the The car 8 is on standby with the door closed, so the user can be kept away from fire and smoke, and the user can be quickly moved to the evacuation floor after the fire extinguishing operation, and the rescue efficiency of the user can be further improved.

Furthermore, since the evacuation floor priority information is set according to the rescue difficulty of each floor, even if a fire breaks out on the first evacuation floor (hall floor), the user can be moved to the second evacuation floor where rescue is next easier. , for example, can make the rescue operations of rescuers such as firefighters easier, and can further improve the user's rescue efficiency.

Moreover, when a fire breaks out in the building, the operation control unit 61 invalidates the call registration from the floor where the fire is breaking out, and makes the hall broadcasting device 25 and the hall display device 27 arranged at the hall of the floor report an alarm. Knowing that the call registration is set as invalid, it is possible to urge users on the fire floor to evacuate by means other than the elevator device, and it is possible to reduce the possibility that the car 8 returns to the fire floor, which can further improve User rescue efficiency.

In addition, in Embodiment 1, the building in which the elevator apparatus was installed was described as an 8-story building, but the structure of the building may be arbitrary.

Furthermore, in Embodiment 1, the eighth floor where rescue by helicopter is used is described as the second evacuation floor, but the priority order of evacuation floors may be set according to the difficulty of rescue for each floor. For example, when rescue by helicopter is difficult due to the structure of the building, the floor where rescue can be performed using a ladder car may be set as the second evacuation floor. Furthermore, the order of priority of the floor where the communication passage with the adjacent building is provided may be made higher.

Moreover, in Embodiment 1, it was explained that the elevator control device 16 judges whether there is a user in the car 8 based on both signals of the weighing device 38 and the camera 37 in the car, but it may also be determined only based on the weighing device and the camera 37. It is determined whether or not there is a user in the car 8 based on a signal from one of the cameras in the car.

Moreover, in Embodiment 1, it was explained that when a fire breaks out in a building, the elevator control device 16 determines whether there is room for a user to board in the car 8, and when it is determined that the car 8 is full, the elevator control device 16 uses The car 8 goes directly to the evacuation floor, but even if only one person is seated in the car 8, the car may go directly to the evacuation floor.
