Description

Elevator evacuation support device

This invention relates to an elevator evacuation support apparatus for evacuating a resident who is left in a building when a fire occurs in the building.

Conventionally, an elevator operation method has been proposed in which each elevator group individually performs control operation to stop a car on the nearest floor when a fire occurs in a building where a plurality of elevator groups are installed. Each elevator group is set with a priority order for starting the control operation based on the fire occurrence floor. The control operation is started in the order of the set elevator groups with the highest priority. Thereby, the continuation time of normal operation of the elevator group with little influence of a fire can be extended (refer patent document 1).

Japanese Patent Laid-Open No. 5-8954

However, in recent buildings, since the technology of fire prevention compartments has advanced, the possibility of fires on the floors other than the floor where the fire occurred and the floor directly above it is low. Moreover, even if it is a fire outbreak floor or a floor directly above it, the fire may not reach the elevator depending on the location of the fire. Therefore, in recent buildings, there are many cases where there is no problem even if the operation of the elevator is continued even if a fire occurs.

The conventional elevator operation system as described above can only extend the duration of normal operation of some elevator groups, and after the car has been stopped due to control operation, Cannot be transported to the evacuation floor. Accordingly, the transportation efficiency of the residents in the event of a fire is reduced. In particular, if the occupants left in the building are, for example, disabled people, it is difficult to move the evacuation stairs of the building, so it is normal for disabled people to move to the evacuation floor after the car stops. It will be more difficult than the person.

The present invention has been made to solve the above-described problems, and even if the occupants left in the building include persons with disabilities, for example, the occupants are transported to the evacuation floor. It is an object of the present invention to provide an elevator evacuation support apparatus that can suppress a decrease in efficiency.

The elevator evacuation support apparatus according to the present invention is an elevator evacuation support apparatus that performs an evacuation operation for an elevator in a fire in order to transport a resident who is left in a building including a plurality of floors to an evacuation floor. Of the general-purpose call input devices and specific-person call input devices provided on each floor, only the floor where the specific-person call input device was operated is registered as a dedicated response floor. Dedicated call response operation means for performing an exclusive call response operation as an evacuation operation in which the elevator cars respond in the order of the dedicated response floor having the highest degree of urgency based on information from the fire detector provided at.

Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an evacuation system including an elevator evacuation support apparatus according to Embodiment 1 of the present invention. In the figure, a plurality of elevators 1 are installed in a building. The building is a high-rise building including a plurality of floors. The elevator 1 has a plurality of elevators 2. Further, the elevator 1 is provided with a group management device 3 that manages the operation of each elevator car 2 as a group. Each elevator 2 is provided with a control device 4 that controls the operation of the elevator 2 under the management of the group management device 3.

Each elevator 2 has a car 5 that can carry, for example, passengers and luggage. The car 5 can be stopped on a predetermined floor. The movement of the car 5 is controlled by the control device 4.

At the landing on each floor, a normal hall button device (general user call input device) 6 for performing call registration of the car 5 from the hall and an emergency hall button device (specific user call input device) 7 is provided. The

landing button devices

6 and 7 for normal and emergency use generate a landing call by receiving a predetermined operation. The emergency landing button device 7 is arranged at a position lower than the position of the normal landing button device 6. Therefore, the emergency landing button device 7 is disposed at a position where it can be operated not only by a healthy person but also by a disabled person or an elderly person. The emergency landing button device 7 is displayed as an emergency (fire) dedicated landing button device (emergency dedicated display). It should be noted that in the emergency hall button device 7, a display indicating that the hall button device is dedicated to a specific person (handicapped person or elderly person) (specific person-only display) may be provided in addition to the emergency dedicated display. Good.

Each floor of the building is provided with a plurality of fire detectors 8 that detect the occurrence of a fire, and an emergency broadcast device 9 that performs guidance broadcasting regarding evacuation guidance to the entire building in an emergency (for example, in the event of a fire). . The fire detectors 8 existing on the common floor are arranged at different positions with respect to the hall of the elevator 1. Information from each fire detector 8 is sent to a disaster prevention management apparatus 10 that manages and manages disaster prevention equipment for the entire building. Based on the information from each fire detector 8, the disaster prevention management device 10 detects whether or not a fire has occurred and identifies the floor where the fire has occurred.

Information from the disaster prevention management device 10 is sent to an evacuation support device 11 that manages each group management device 3 in the event of a fire. The evacuation support apparatus 11 manages the respective group management apparatuses 3 after the occurrence of a fire is detected by the disaster prevention management apparatus 10, thereby evacuating the remaining residents in the building (for example, the entrance floor of the building). The evacuation operation for transporting to each elevator 1 is performed. The disaster prevention management device 10 and the evacuation support device 11 are provided in a management room (disaster prevention center) that centrally monitors and controls facility equipment related to disaster prevention.

The evacuation support apparatus 11 includes communication means 12, fire condition determination means 13, zone division means 14, reciprocating operation means 15, and dedicated call response operation means 16.

The communication means 12 performs information communication between each of the group management device 3 and the disaster prevention management device 10 and the evacuation support device 11. Landing calls from the normal and emergency

landing button devices

6 and 7 are sent to the evacuation support device 11 via the group management device 3.

Fire condition determination means 13 specifies the range of fire spread on each floor by calculation based on information from each fire detector 8 and disaster prevention management device 10. The evacuation support device 11 determines whether or not the evacuation operation of each elevator 1 is possible based on the calculation result of the fire situation determination means 13.

The zone dividing unit 14 sets a plurality of zones different from each other in the height direction of the building. Each zone includes a plurality of floors. Each zone is set corresponding to each elevator 1.

The round trip operation means 15 makes at least one of the floors a rescue floor. The rescue floor is set based on each zone set by the zone dividing means 14. In this example, when a rescue floor is set in the zone, the top floor of the zone is the rescue floor. The reciprocating operation means 15 generates an evacuation operation command for performing the reciprocating operation for reciprocating the car 5 between the set rescue floor and the evacuation floor as the evacuation operation. In the elevator 1 that has received the evacuation operation command, a reciprocating operation is performed in which the car 5 is moved between the rescue floor set in the corresponding zone and the evacuation floor.

The dedicated call response operation means 16 performs call registration using only the floor where the emergency landing button device 7 is operated as the dedicated response floor. In other words, the dedicated call response operation means 16 sets only the landing call from the emergency landing button device 7 as a call registration target, and excludes the landing call from the normal landing button device 6 from the call registration target. .

Also, the dedicated call response operation means 16 calculates the urgency of the dedicated response floor based on the range of fire spread obtained by the fire condition determination means 13. In this example, when the fire occurrence floor is included in the dedicated response floor, the urgency level of the fire occurrence floor is the highest. Further, when the floor above the fire occurrence floor is included in the dedicated response floor, the degree of urgency is gradually reduced as the distance from the fire occurrence floor increases. Furthermore, if the floor below the fire floor is included in the dedicated response floor, the urgency of the floor below the fire floor is made lower than that of the floor above the fire floor. .

Furthermore, the dedicated call response operation means 16 generates a dedicated call operation command for performing the dedicated call response operation as an evacuation operation in which the car 5 is made to respond in the order of the dedicated response floor with the highest degree of urgency. The elevator 1 that has received the dedicated call operation command performs a dedicated call response operation for each elevator car 2. In the elevator 1 when the dedicated call response operation is performed, the car 5 is responded only to the dedicated response floor in the corresponding zone.

Here, FIG. 2 is a conceptual diagram for explaining the dedicated call response operation by the dedicated call response operation means 16 of FIG. In this example, the case where the elevator No. 2 included in the elevator 1 is designated as No. A and No. B will be described. In this example, six floors are registered as dedicated response floors, and among the six dedicated response floors, four dedicated response floors exist above the fire occurrence floor, and the remaining two dedicated floors. The case where the response floor exists below the fire floor will be described.

In the dedicated call response operation, the car 5 responds only to the hall call from the emergency hall button device 7, so there is a high possibility that the people who are in the car 5 include disabled persons or elderly people. For example, when a resident who uses a wheelchair or the like gets on the car 5, the necessary space in the car 5 becomes larger than that of a general passenger. Accordingly, in the dedicated call response operation, the car 5 responds in one scan (a series of operations from the time when the car 5 leaves the evacuation floor to the arrival of the call again after sequentially responding to the landing call). The number of hall calls is limited. The upper limit value of the number of hall calls to which the car 5 responds is set based on the capacity of the car 5 and the space of the wheelchair. In this example, the upper limit value of the number of hall calls to which the car 5 responds in one scan is set to two.

In the case shown in FIG. 2 where six floors are called and registered as dedicated response floors, the urgency of the four floors existing above the fire floor is below the fire floor. It will be higher than the urgency of the two floors. In addition, the urgency levels of the four floors existing above the fire occurrence floor are gradually lowered as the distance from the floor near the fire occurrence floor increases.

In this case, first of all, the car 5 of Unit B responds to the hall call from the two dedicated response floors near the fire occurrence floor among the four dedicated response floors existing above the fire occurrence floor. The car 5 of the No. A machine responds to the hall call from the two dedicated response floors away from the generation floor. Thereafter, the car 5 of the Unit B arrives at the evacuation floor, and the car 5 of the Unit A arrives at the evacuation floor. The car 5 of the Unit B arriving at the evacuation floor responds to the hall call from the two dedicated response floors existing below the fire occurrence floor after taking the passenger down to the evacuation floor. Thereafter, the car 5 of the Unit B returns to the evacuation floor and lowers the passenger to the evacuation floor. In this way, the dedicated call response operation is performed.

The evacuation support device 11 performs setting for each zone so that the evacuation operation is at least one of a round trip operation and a dedicated call response operation. That is, for the evacuation operation of the elevator 1, the evacuation support apparatus 11 sets any one of the settings for the reciprocating operation only, the setting for the dedicated call response operation, and the setting for the combined operation of the reciprocating operation and the dedicated call response operation for each zone. select. The setting of the evacuation operation of the elevator 1 is performed based on the information of the zone dividing means 14 and the fire occurrence floor. In this example, the evacuation support apparatus 11 sets only the dedicated call response operation for the evacuation operation of the elevator 1 corresponding to the zone including the fire occurrence floor, and the elevator 1 corresponding to another zone outside the fire occurrence floor. For the evacuation operation, set the combined operation of the round-trip operation and the dedicated call response operation.

FIG. 3 is a schematic diagram showing a building in which a plurality of zones are set by the zone dividing means 14 of FIG. In this example, three elevators 1 are installed in a 40-story building. Therefore, three zones (lower zone 17, middle zone 18 and upper zone 19) corresponding to each elevator 1 are set in the building by the zone dividing means 14.

In this example, the 2nd to 10th floors of the building are included in the lower zone 17, the 11th to 20th floors are included in the middle zone 18, and the 21st to 40th floors are in the upper zone 19. Included. The evacuation floor is the first floor. The setting data for each of the zones 17 to 19 and the evacuation floor is stored in advance in the evacuation support apparatus 11.

When the 30th floor portion of the building becomes a fire occurrence floor, the evacuation support apparatus 11 sets the evacuation operation of the elevator 1 corresponding to the upper zone 19 including the fire occurrence floor only to the dedicated call response operation, and other lower zone zones 17 and The evacuation operation of the elevator 1 corresponding to each of the middle zone 18 is a combined operation of the reciprocating operation and the dedicated call response operation. Therefore, the rescue floor is not set in the upper zone 19, and only the uppermost floors (10th floor and 20th floor) of the lower zone 17 and the middle zone 18 are set as rescue floors.

Thereby, in the elevator 1 corresponding to the lower zone 17, the reciprocating operation between the rescue floor (10th floor) and the evacuation floor (first floor) in the lower zone 17 is basically performed. A dedicated call response operation is performed when an evacuation response floor occurs. In the elevator 1 corresponding to the middle zone 18, a reciprocating operation is basically performed between the rescue floor (20th floor) and the evacuation floor (first floor) in the middle zone 18, and evacuates into the middle zone 18. A dedicated call response operation is performed when a response floor occurs.

On the other hand, in the elevator 1 corresponding to the upper zone 19, the reciprocating operation is not performed, and the dedicated call response operation is performed only when the evacuation response floor is generated in the upper zone 19.

If a person on the floor other than the rescue floor heads to the rescue floor, it will move between the floors using stairs. If the resident is a disabled person or an elderly person and cannot move up the stairs, the resident will generate a landing call on the evacuation response floor by operating the landing button device 7 for emergency. .

The evacuation support apparatus 11 is composed of a computer having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, etc.) and a signal input / output unit. The functions of the communication unit 12, the fire condition determination unit 13, the zone division unit 14, the reciprocating operation unit 15, and the dedicated call response operation unit 16 are realized by a computer of the evacuation support device 11.

That is, a program for realizing the functions of the communication means 12, the fire condition determination means 13, the zone dividing means 14, the reciprocating operation means 15, and the dedicated call response operation means 16 is stored in the storage unit of the computer. The arithmetic processing unit executes arithmetic processing related to the function of the evacuation support apparatus 11 based on a program stored in the storage unit.

Next, the operation will be described. FIG. 4 is a flowchart for explaining the operation of the evacuation system of FIG. As shown in the figure, when the occurrence of a fire is confirmed by the disaster prevention management device 10 (S1), confirmed information on the occurrence of the fire is sent from the disaster prevention management device 10 to the evacuation support device 11. As a result, the operation of each elevator 1 is set to fire control operation, and the moving car 5 stops at the nearest floor and waits for door opening (S2).

When the evacuation support apparatus 11 receives the confirmed information of the occurrence of the fire and the range of the fire spread is specified by the fire condition determination means 13, the evacuation support apparatus 11 determines whether or not the evacuation operation can be performed for each elevator 1 (S3). . When it is determined that the evacuation operation cannot be performed, the process of the evacuation support apparatus 11 ends.

If it is determined that the evacuation operation can be performed, a plurality of zones 17 to 19 corresponding to each elevator 1 are set by the zone dividing means 14 (S4).

After this, the evacuation support apparatus 11 selects each operation of the reciprocating operation only, the exclusive call response operation only, or the combined operation of the reciprocating operation and the exclusive call response operation for each of the zones 17-19. In this example, only the dedicated call response operation is selected for the upper zone 19 including the fire occurrence floor, and the combined operation of the reciprocating operation and the dedicated call response operation is selected for each of the other lower zone 17 and the middle zone 18. The

Thereafter, only the uppermost floors (the 10th floor and the 20th floor) of the lower zone 17 and the middle zone 18 subject to the round trip operation are set as rescue floors by the round trip operation means 15 (S5).

Thereafter, the evacuation operation selected above is performed for the elevator 1 corresponding to each of the zones 17 to 19. That is, the combined operation is performed for the elevator 1 corresponding to each of the lower zone 17 and the middle zone 18, and only the dedicated call response operation is performed for the elevator corresponding to the upper zone 19 (S6). At this time, the in-house broadcast by the emergency broadcast device 9 is performed by the management of the evacuation support device 11. Thereby, the information regarding the evacuation operation of each elevator 1 is notified to the residents.

Thereafter, the evacuation support apparatus 11 determines whether or not the evacuation operation end condition is satisfied (S7). As a condition for ending the evacuation operation, for example, when there is no car 5 on the rescue floor during a round-trip operation for a predetermined time or more, or an emergency landing button device 7 during a dedicated call response operation. There is a case where the hall call by the operation does not occur for a predetermined time or more.

Evacuation operation of each elevator 1 is continued when the evacuation operation end condition is not satisfied. When the termination condition is satisfied, the evacuation operation of each elevator 1 is terminated by a termination command from the evacuation support apparatus 11 to the group management apparatus 3 (S8).

In such an elevator evacuation support apparatus 11, only the floor where the emergency landing button device 7 was operated is called and registered as a dedicated response floor, and the cars 5 are made to respond in the order of the dedicated response floor with the highest urgency. Since the dedicated call response operation is an evacuation operation, it is possible to preferentially rescue a specific occupant (for example, a disabled person or an elderly person) who operates the emergency landing button device 7 and a dedicated response floor. It is possible to efficiently rescue a specific resident who is present at a priority order. Therefore, even if the residents remaining in the building include, for example, disabled persons or elderly people, it is possible to suppress a decrease in the transportation efficiency of the residents to the evacuation floor.

Moreover, in addition to the dedicated call response operation, a reciprocating operation in which the car 5 is moved between the rescue floor and the evacuation floor can be implemented as an evacuation operation, so that the people in the building can be transported to the evacuation floor more efficiently. can do.

In addition, a plurality of zones 17 to 19 different from each other in the height direction of the building are set in the building, and at least one of the dedicated call response operation and the reciprocating operation is set for the evacuation operation for each zone 17 to 19. Evacuation operations can be performed according to individual conditions in zones 17-19. Accordingly, it is possible to more efficiently carry the residents present in the zones 17 to 19 to the evacuation floor.

Further, since the call input device for specific person is the emergency landing button device 7, it can be operated only in an emergency, and the normal operation of the call input device for specific person can be prevented.

In the above example, of the zones 17 to 19, only the zone 19 including the fire floor is excluded from the target of reciprocating operation. However, the present invention is not limited to this. The choice of driving may be made freely. For example, in addition to the zone including the fire occurrence floor (fire occurrence zone), the zone immediately above the fire occurrence zone (zone immediately above the fire) may be excluded from the target of the reciprocating operation. That is, each of the fire occurrence zone and the zone directly above the fire may be set as a target for the dedicated call response operation only.

In the above example, the zones 17 to 19 are determined in advance, but a plurality of zones may be set in the building based on the fire occurrence floor. For example, the fire occurrence floor may be divided into upper and lower zones with a boundary.

In the above example, either the reciprocating operation only, the dedicated call response operation only, or the combined operation of the reciprocating operation and the dedicated call response operation is selected based on the fire occurrence floor. Along with the occurrence floor, for example, the selection may be made based on the number of people in the building (such as healthy persons and disabled persons) registered in advance on each floor.

In the above example, either the reciprocating operation only, the dedicated call response operation only, or the combined operation of the reciprocating operation and the dedicated call response operation is selected based on the fire occurrence floor. You may make it perform selection of said each operation | movement based on the installation state of the fire equipment (for example, smoke shielding equipment, waterproofing equipment, etc.) on a floor.

In the above example, the emergency landing button device 7 is used as the call input device for the specific person. However, the present invention is not limited to this. For example, an individual who reads personal information recorded on a card or IC tag. An identification device (such as a card reader) may be used as a specific person call input device. By using the personal identification device as a specific person call input device, it is possible to more reliably identify a disabled person or the like.
