Description

FIRE EVACUATION OPERATION DEVICE FOR GROUP-CONTROLLED ELEVATORS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire evacuation driving apparatus for a group managed elevator that can efficiently evacuate using an elevator in the event of a fire in a high-rise building.

In general, in the event of a fire in a building, each elevator travels to the nearest floor and then stops further operation. This is mainly because the purpose of the prevention of secondary disasters caused by elevators. In other words, the fire control operation of a normal elevator causes the door to be opened in order to prevent the passengers from being trapped, while going straight to the evacuation floor of the elevator in order to evacuate passengers who have already climbed up in the event of a fire. It is maintained for a long time, after which the use of an elevator in the case of a fire is prohibited to prevent secondary disasters.

In addition, there is also an emergency elevator of a special structure that is used by firefighters and the like in the event of a fire separately from the normal elevator.

However, in recent buildings, technologies other than the fire protection section are improved, and the floors except the fire generating floor and the adjacent floors are less affected, and the elevator is also configured to have no problem even if it continues to operate normally.

As an elevator driving method in consideration of this, for example, in the case of a fire in a high-rise building, a fire control operation (traveling to the nearest floor and stopping) is performed to an elevator group serving a zone including a fire generating layer, Priority is set below to fire control operation to each zone one by one. Thereby, the time to continue normal operation in the floor which has little influence on a fire is extended (for example, refer patent document 1).

Moreover, for example, according to the information from the fire detection means provided in each stairway, it is made to guide | induce to the floor which can evacuate a fire generating layer safely (for example, refer patent document 2).

Patent Document 1: Japanese Patent Laid-Open No. 5-8954

Patent Document 2: Japanese Patent Laid-Open No. 5-147849

However, in the former prior art, the time for performing normal operation is also slightly extended even for an elevator serving a safe floor, and there is no configuration in which the elevator is actively used or provided as an evacuation means. Similarly, the latter conventional technique only changes the evacuation floor according to the fire generation floor, and generally does not constitute a configuration in which the elevator is actively used or provided as an evacuation means.

The present invention has been made in order to solve the above problems, paying attention to the fact that the stairs other than the fire generating layer or the upper floor above the fire generating layer are less affected by the improvement of technology outside the fire protection section of the building. It is to provide an evacuation operation device in case of fire of a group-managed elevator which can enable evacuation of a large number of people in a short time by actively providing a safe elevator as an evacuation means depending on the location.

The fire evacuation driving device of the group management elevator according to the present invention divides the stairs to be serviced into a plurality of service zones, and has a plurality of elevators serving each service zone from the entrance floor, and a fire detector installed in each step of the building. Causes each elevator to stop on the nearest floor when it detects a fire, and in the event of a fire, it is determined that evacuation operation is impossible for the elevator serving the zone including the fire generating floor. The elevator which stops the operation after stopping, and serves the zone which does not contain a fire generating floor, and evacuation operation availability determination means judged as evacuation operation possible, and evacuation operation acceptance determination means judged as evacuation operation possible. Depending on the stairs that caused the fire to the elevator Is provided with a evacuation operation command means for performing the evacuation support of building jaegwan by the reciprocating between the rescue floor setting means, the entrance layer and the rescue floor to the evacuation floor the elevator is to set chulcheung.

Further, the rescue floor setting means sets a rescue floor in a transit floor between the zone and one zone below the zone located above the zone including the fire generating layer, and includes the fire generating layer. For the zone located below, the rescue layer is set in the transition layer between the zone and the zone above one zone.

In addition, the evacuation operation permission determining means stops the operation of the elevators in the zones sharing the transit floor when the fire generation floor is the transit floor between the zones.

The rescue layer setting means sets the rescue layer in the upper vicinity of the transit layer when the fire generating layer is the lower vicinity of the transition layer between the zones.

In addition, the fire evacuation driving device of the group management elevator according to the present invention divides the stairs to be serviced into a plurality of service zones, and has a plurality of elevators to service each service zone from the entrance floor, and is installed on each of the stairs of the building. When the fire detector detects a fire, the elevators are stopped at the nearest floor. In the event of a fire, each elevator in the zone including the fire generating floor is stopped after each elevator is stopped at the nearest floor. The fire zone rescue floor setting means for setting the rescue layer in the upper or lower transit floor of the zone serviced by the fire generating floor according to the location of the fire generating floor and the zone located above the zone including the fire generating layer. Set up a rescue layer on the transition layer between the zone and one of the zones below, and also include the fire generating layer. For zones located below the zone, non-fire zone rescue floor setting means for setting the rescue floor in the transit floor between the zone and one zone above, between the entrance floor and the rescue floor where each elevator becomes an evacuation floor. It is equipped with the evacuation operation command means which performs evacuation support of a building inspector by making a round trip.

The fire zone rescue floor setting means sets the rescue floor of the elevator serving the top zone when the fire generating floor is the top zone to the lower transit floor of the top zone, and when the fire generating floor is not the top zone. If the fire-generating floor is located above the zone containing the floor, the rescue floor of the elevator serving the zone is set to the upper transit floor of the zone, and the other floor is rescued to the lower transit floor of the zone. To set the floor.

The fire zone rescue floor setting means excludes the transition layer from the selection candidate for the rescue floor when the fire generating layer is a transit layer between zones or a layer immediately below it.

Further, the fire zone rescue floor setting means includes a case in which the fire generating layer is a transit layer between zones or a layer immediately below it, when the transit layer is excluded from the candidate for selection of the rescue layer, and when there is another serviceable transit layer. Is to set the rescue layer on the floor.

As described above, according to the present invention, even in the event of a fire in a high-rise building, an elevator is actively provided as an evacuation means according to the location of the fire-generating floor, whereby a building occupant evacuates by using a staircase and an elevator together. It is possible to do it and has effect that can evacuate a large number of people in a short time.

In addition, for a zone located above the zone including the fire generating layer, a rescue layer is set in the transition layer between the zone and one zone below, and for a zone located below the zone including the fire generating layer. By setting the rescue floor in the transit floor between the zone and one zone above, it is possible to make the step movement distance of the building inspector even, and also because each elevator stops only on the evacuation floor and the rescue floor. It has the effect of being able to advance and evacuate a large number of people in a short time.

In the case where the fire generating layer is a transit layer between zones, the operation of the elevator in the zone sharing the transit layer is stopped, so that the evacuation can be performed using a safe elevator.

In addition, when the fire-generating floor is the lower floor near the transit floor between zones, by setting the rescue floor in the upper floor near the transit floor, each elevator can perform rescue activities by reciprocating operation with the safe floor. Has the effect.

If the fire generating layer is the highest zone, the rescue layer of the elevator serving the top zone is set to the lower transit layer of the top zone, and if the fire generating layer is not the top zone, the fire generating layer is the floor. In the case of located above the zone including the above, by setting the rescue floor of the elevator serving the zone to the upper transit floor of the zone, otherwise setting the rescue floor to the lower transit floor of the zone, The number of elevators that can be boarded by reinspectors in the zone with the highest risk due to the fire increases, which has the effect that evacuation can be carried out quickly.

In addition, when the fire generating layer is a transit layer between the zones or the layer immediately below it, the evacuation layer can be removed from the selection candidates for the rescue layer, thereby enabling safe evacuation operation.

If the fire-generating layer is a transit layer between zones or a layer below it, when the transit layer is excluded from the selection candidate for the rescue layer, and if there is another serviceable transit layer, the rescue layer is placed on the layer. By setting it, it has the effect that an evacuation operation is performed using all the elevators which can be operated.

EMBODIMENT OF THE INVENTION In order to demonstrate this invention in detail, this is demonstrated with reference to attached drawing.

Example 1

EMBODIMENT OF THE INVENTION Hereinafter, the fire escape apparatus of the group management elevator in Example 1 of this invention is demonstrated. BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram which shows the example of the whole structural function by the function of the evacuation operation apparatus at the time of fire of the group management elevator in Example 1 of this invention. In FIG. 1, 1 is an evacuation plan preparation device which creates an elevator evacuation plan, and gives instructions, 2 is a disaster prevention management device which manages and integrates disaster prevention equipment of the whole building, 3 is a fire detector installed in each floor, 4 is the same It is an emergency broadcasting apparatus installed in each floor, and announces about evacuation guidance in case of emergency. 5 is an elevator group management apparatus which manages and controls an elevator group.

Moreover, the evacuation plan preparation device 1 of FIG. 1 includes the following means of each of 1A-1D, and each of these means of 1A-1D is comprised by the software on a microcomputer. 1A is a communication means for performing information communication with each elevator group management control device 5, etc., 1B is an evacuation operation permission determination means for determining whether to operate an elevator serving each zone, and 1C is an evacuation according to the location of the fire generation floor. Rescue floor setting means for setting a rescue floor in the case of driving, 1D is an evacuation operation command means for giving an evacuation operation command to each elevator group management control device 5.

Next, the operation in Embodiment 1 of the present invention will be described with reference to Figs.

Fig. 2 is a flowchart showing the outline of the operation in the first embodiment of the present invention. 3 and 4 are explanatory diagrams for explaining the rescue layer setting operation in the first embodiment of the present invention.

First, when a fire occurrence is confirmed after a fire is detected by the fire detector 3 of FIG. 1, the determination information of the fire occurrence is prepared from the disaster prevention management apparatus 2 of FIG. 1 in step S100 in FIG. 2. To the device 1. Thereafter, in step S101, each elevator shifts to an operation called fire control operation. In this fire control operation, the elevator on the run stops on the nearest floor, open the door and get off the passenger.

After that, in step S102, evacuation operation permission determination means 1B determines whether or not evacuation operation is performed for the elevator group serving each zone.

In this case, since it is basically safe for the elevator group serving the fire generating layer 11, it is determined that evacuation operation is impossible and the operation is stopped, and the flow proceeds to step S106. In addition, it is determined that evacuation operation is possible for the elevator group which does not include the fire generating layer 11 in the service stairs, and the flow proceeds to step S103.

Next, in step S103, a rescue floor is set according to the fire occurrence position for each elevator group determined to be evacuation operation possible in step S102. Hereinafter, the setting of this rescue layer is demonstrated using FIG. 3, FIG.

3 shows an example of a building in which an elevator serving three zones, which are a low-rise zone, a middle-zone zone, and a high-rise zone, is commissioned. That is, the elevator in the high-rise zone (the elevator on the right side of FIG. 3) serves each floor of the entrance floor and the high-rise zone, and the elevator in the middle-tier zone (the elevator in the center of FIG. 3) serves each floor of the entrance floor and the middle floor zone. For example, the elevator of the lower floor zone (the elevator on the left side of FIG. 3) serves as an example of serving each floor of the entrance floor and the lower floor zone. In addition, the entrance layer becomes the evacuation layer 10 at the time of a fire.

Here, as shown in the example of FIG. 3, the case where a fire generate | occur | produces in the layer contained in a middle layer zone is demonstrated as an example.

In the example of FIG. 3, first, the elevator of the middle floor zone containing the fire generating layer 11 is determined to be operation stop by the determination of step S102. For elevators in the upper zone, the transit layer in the upper and middle zones is set as the rescue layer 12. In addition, about the elevator of a lower floor zone, the transit floor of a middle floor / lower floor zone is set as the rescue floor 13.

As a result, the upper zone relocation officer can move to the rescue floor 12, which is the transit floor of the upper / middle floor zone, and then move to the entrance floor of the evacuation floor 10 by getting on the elevator in the upper zone. In addition, the middle-floor residing person moves up the stairs to the rescue floor 13, which is the transit floor of the middle / low floor zone, and then boards the elevator in the lower-floor zone and moves to the entrance floor, which is the evacuation floor 10. In addition, lower floor residents evacuate by stairs.

In this way, the transition layer between the magnetic zone and the zone below the magnetic zone is basically set as the rescue layer 12 for the zone above the fire generating layer 11. In the zone below the fire generating layer 11, the transition layer between the magnetic zone and the zone above the magnetic zone is set as the rescue layer 13.

As a general human psychology, in the event of a disaster such as a fire, the building's inspector moves downward. Therefore, if the transit floor is set as described above, all residing persons except the lowest floor can get on the elevator if they move up the stairs to the lower transit floor of their zone, and the moving distance of the staircase of each zone residing person is almost equal, Only a long distance need not be moved up the stairs. In addition, evacuation can be completed much faster than if the power supply only moves up the stairs.

Next, the rescue floor setting in the case of a fire occurring in the transit layer or the lower vicinity of the transit layer will be described with reference to FIG. 4.

Fig. 4A shows an example where a fire occurs in the transit layer in the middle / lower layer zone. In such a case, the elevators in the middle floor / lower floor zones have a fire on their service floor, and therefore all of the judgments in step S102 determine that evacuation operation is impossible and the operation is stopped. Therefore, reinvestigators in the middle and lower zones will evacuate by stairs. In the elevator of the upper zone, as described above, the rescue layer 12 is set in the transit layer of the upper / middle layer zone, and the re-inspector of the upper zone from the rescue layer 12 can evacuate to the elevator.

In addition, although not shown in the figure, when a fire breaks out on the floors to which each elevator serves in common, such as the entrance floor, all the elevators are judged to be in operation stop in step S102.

4 (b) shows an example in the case where a fire occurs in the lower layer of the transit layer of the upper / middle layer zone. In such a case, the elevator in the middle floor zone has a fire on the floor serviced by the self, and therefore, it is determined that evacuation operation is impossible in the determination of step S102 and the operation is stopped.

The elevator in the upper floor zone is determined to be evacuable in step S102. However, if a fire occurs immediately below, the fire may also spread on the transit floor, depending on the progress of the fire. Therefore, in consideration of safety margin, the rescue layer 12 for the upper zone zone is shifted to a layer above the transition layer. As this shift method, the following method is considered, for example.

When the fire generating layer 11 is a transit layer-1 layer, the rescue layer is set to a transit layer +2 layer, and when the fire generating layer is a transit layer -2 layer, the rescue layer is set to a transit layer +1 layer.

That is, X (layer) is set as a safety parameter, and when a fire occurs in the transit layer -1 floor-the transit layer -X layer, a rescue layer is set to the fire generation layer + X + 1 layer. The example is a case where X = 2. You may set this value of X suitably according to a building structure.

If the rescue floor is set in step S103 as described above, the flow proceeds to step S104, where evacuation using an elevator is performed.

The elevator that can be evacuated can perform a reciprocating operation between the set rescue floors 12 and 13 and the evacuation floor 10 (normally the entrance floor), and work on the evacuation structure of the inspector. In addition, guidance from the emergency broadcast apparatus 4 provided in each floor is effective and invalidation of elevator evacuation and guidance guidance of which floor the elevator can be boarded from.

The evacuation operation of step S104 is performed until it is determined to end in step S105. As this termination determination condition, the following is considered, for example.

(i) When it is judged to be the end of driving by human judgment such as disaster prevention worker, fire brigade, and is input by the end of driving.

(ii) Safety of elevator operation is threatened by the progress of fire or flooding of fire fighting activities.

(iii) When boarding on rescue floor is lost and evacuation is determined.

(I) is a manual input, (ii), (iii) can be automatically determined by a sensor of an elevator-related facility such as a lift sensor. In addition, the termination determination is not limited to the above.

For example, the operation may be terminated when safety is difficult under certain conditions, and when a condition that determines that evacuation is completed is satisfied.

The above steps S102 to S104 are performed for each elevator group in charge of each zone.

Example 2

EMBODIMENT OF THE INVENTION Hereinafter, the fire escape apparatus of the group management elevator in Example 2 of this invention is demonstrated. Fig. 5 is a block diagram showing an example of the overall configuration of each function of the evacuation driving apparatus in case of fire of the group management elevator according to the second embodiment of the present invention. In FIG. 5, since the same code | symbol is attached | subjected to the same part in FIG. 1, description is abbreviate | omitted and only a difference is demonstrated. 1E is a fire zone rescue floor setting means for setting a rescue floor when an elevator serving a zone including a fire generating floor performs an evacuation operation according to the location of the fire generating floor, and 1F is a zone that does not include a fire generating floor. It is a non-fire zone rescue floor setting means which sets a rescue floor in the case of an elevator to service.

Next, the operation in the second embodiment of the present invention will be described with reference to Figs.

Fig. 6 is a flowchart showing the outline of the operation in the second embodiment of the present invention. 7 and 8 are explanatory diagrams for explaining the rescue layer setting operation in the second embodiment of the present invention.

First, when a fire occurrence is confirmed after a fire is detected by the fire detector 3 of FIG. 5, the determination information of the fire occurrence is generated from the disaster prevention management apparatus 2 of FIG. 5 at step S200 in FIG. 6. To the device 1. After that, in step S201, each elevator shifts to an operation called fire control operation. In this fire control operation, the elevator on the run stops on the nearest floor, open the door and get off the passenger.

Thereafter, in step S202, it is determined whether the rescue floor is set for the elevator group serving each zone. In the second embodiment, as described later in step S203, a rescue layer is basically set in the transit layer of each zone, but there is a case where a fire occurs in the transit layer or the layer immediately below it. In that case, if there is a transit floor which can be serviced elsewhere, the rescue floor is set on the floor, but when there is no transit floor, it is determined that the rescue floor of the zone is impossible, and the flow proceeds to step S206 to determine the elevator floor. Stop operation.

In addition, in the event that a fire occurs on the floor where each elevator has to get off passengers in common, such as the evacuation floor (normal entrance floor), all the elevators are determined to be inoperable in step S202, and the operation proceeds to step S206. Stop.

If the rescue layer can be set in a case other than the above, the process proceeds to step S203.

Next, in step S203, the rescue floor is set according to the fire occurrence position for each elevator group determined to be evacuation operation possible in step S202. Hereinafter, the setting of the rescue layer will be described with reference to FIGS. 7 and 8.

7 shows an example of a building in which an elevator serving three zones, a low-rise zone, a middle-zone zone, and a high-rise zone, is commissioned. That is, the elevator in the high-rise zone (the elevator on the right side in FIG. 7) serves each floor of the entrance floor and the high-rise zone, and the elevator in the middle-tier zone (center elevator in FIG. 7) services each floor in the entrance floor and the middle-tier zone. The case where the elevator in the lower floor zone (the elevator on the left side in FIG. 7) serves each floor of the entrance floor and the lower floor zone is taken as an example. In addition, the entrance layer becomes the evacuation layer 10 at the time of a fire.

First, as shown in the example of FIG. 7A, a case where a fire occurs in a floor slightly lower in the middle floor zone will be described as an example. 11 is a fire generating layer.

In the example of Fig. 7A, it is each floor of the middle zone that is considered the most dangerous in the occurrence of a fire. Therefore, in this case, the evacuation of middle-class residing officers should be prioritized. Therefore, the rescue layer 13 is set in the transit layer of a middle / low-rise zone about the elevator of a middle layer zone. Also, the elevators in the lower floor below the middle floor zone are set to the transit floor above the zone. As a result, the rescue layer 13 is set in the transit floor of a middle / low floor zone similarly to the elevator of a middle floor zone. As a result, the middle-floor resident can move up the stairs to the transit floor of the middle / low floor zone, and then quickly move to the evacuation floor (the entrance floor) using both the elevator in the middle-floor zone and the elevator in the low-floor zone. have.

In addition, about the elevator of an upper zone, the transit layer of the upper layer / middle layer below the said zone is set as rescue layer 12. As shown in FIG. The upper zone residing person may move up the stairs to the transit floor of the upper / middle floor zone and then move from the elevator of the upper zone to the evacuation floor (the entrance floor). In addition, low-rise residing officers will evacuate by stairs.

Next, Fig. 7 (b) will be described as an example. In this example, a fire occurs slightly above the middle zone, and 11 is a fire generating layer. In this case, when the fire spreads, the risk of the upper zone is higher than that of the middle zone. For this reason, the evacuation of the upper-zone zone supervisors is given priority over the middle-zone zone, and the rescue layer 12 is set in the transit floor of the upper / middle-zone zone for the elevator of the middle-zone zone. On the other hand, as for the elevator of the upper zone and the elevator of the lower zone, rescue layers 12 and 13 are set in the transit layer of the upper and middle zones and the middle / low layer zone transit layers, respectively, as in the case of FIG. . As a result, the upper-floor resident can move to the transit floor of the upper / middle-floor zone on the stairs, and then evacuate quickly using both the elevator in the upper-zone zone and the elevator in the middle-floor zone. In addition, the middle floor residing officer evacuates by the elevator of the lower floor zone, and the low floor residing officer evacuates by the stairs.

In this way, in the zone including the fire generating layer 11, the rescue layers 12 and 13 are set in one of the upper and lower transit layers depending on the location of the fire generating layer. In addition, a transition layer between the magnetic zone and the zone below the magnetic zone is set as the rescue layer 12 for the zone above the fire generating layer 11, and the magnetic zone and the magnetic zone for the zone below the fire generating layer 11. The transition layer with the zone above the zone is set as the rescue layer 13.

In this way, the inspector of the zone who should give priority to evacuation by fire can evacuate using more elevators.

As shown in Figs. 7A and 7B, X (floor) is set as a parameter as to whether the rescue floor is set to one of the transit floors of the elevator in the zone including the fire generating layer 11. When the fire has occurred in the upper transit layer -2 to the transit layer -X layer, the rescue layer is set as the upper transit layer. You may set this value of X suitably according to a building structure.

Next, the rescue floor setting in the case of a fire occurring in the transit layer or immediately below the transit layer will be described with reference to FIG. 8.

Fig. 8A shows an example in the case where a fire occurs in the transition layer in the middle / low floor zone. 11 is a fire generating layer. In such a case, the elevator in the low-rise zone has a fire in the transit floor serviced by the self, and since there is no transit floor to which the rescue floor must be set, it is determined that the rescue floor cannot be set by the determination in step S202 and the operation is stopped. do. Therefore, reinvestigators in the middle / low floor zones will evacuate by stairs.

In addition, since the rescue floor cannot be set in the transit floor of the middle / low floor zone, the elevator in the middle floor zone is configured to set the rescue floor 12 as the transit floor of the upper / middle floor zone instead. In the elevator of the upper zone, the rescue layer 12 is set in the transit layer of the upper / middle layer zone as described above. Therefore, the upper zone residing officer can evacuate from the rescue floor 12 which is the transit floor of the upper / middle layer zone by using both the elevator of the upper zone and the elevator of the middle zone.

8 (b) shows an example in the case where a fire occurs in the transition layer in the upper / middle layer zone. 11 is a fire generating layer. In such a case, the elevator in the upper floor zone fires in the transit floor serviced by the self, and since there is no transit floor to which the rescue floor must be set, it is determined that the rescue floor cannot be set by the determination in step S202 and the operation is stopped. do. Moreover, since the rescue floor cannot be set in the transit floor of the upper / middle-zone zone, the elevator in the middle-middle zone is set instead to the rescue floor of the middle / low-rise zone. Therefore, the re-inspector in the upper / middle floor zone moves to the transit floor of the middle / low floor zone by stairs, and evacuates using both the elevator in the middle floor zone and the elevator in the lower floor zone.

Although not shown, when a fire occurs in the evacuation floor (main entrance floor), all the elevators are determined to be in operation stop in step S202.

As described above, when the rescue floor is set in step S203, the flow advances to step S204 to evacuate using the elevator.

The elevator capable of evacuation operation performs a reciprocating operation between the set rescue floor and the evacuation floor (normally the entrance floor), and works on the evacuation structure of the inspector. In addition, guidance from the emergency broadcast apparatus 4 provided in each floor is effective and invalidation of elevator evacuation and guidance guidance of which floor the elevator can be boarded from.

The evacuation operation of step S204 is continued until it is determined to end in step S205. As this termination determination condition, the following is considered, for example.

(i) When it is judged to be the end of driving by human judgment such as disaster prevention worker, fire brigade, and is input by the end of driving.

(ii) Safety of elevator operation is threatened by the progress of fire or flooding of fire fighting activities.

(iii) When there is no boarding at rescue floor and it is determined that evacuation is completed.

(I) is a manual input, (ii), (iii) can be automatically determined by the sensor of the elevator-related equipment, such as the elevator sensor. In addition, the termination determination is not limited to the above. Operation is terminated when safety is difficult under certain conditions and when a condition that can be determined that evacuation is completed is satisfied.

The above steps S201 to S206 are performed for each elevator group in charge of each zone.

As described above, it is noted that the fire evacuation driving device of the group management elevator of the present invention is less affected by the fire generation floor or the stairs except the above floor due to the improvement of technology outside the fire protection section of the building. By actively providing a safe elevator as an evacuation means in accordance with the position of the generation floor, evacuation of a large number of people can be enabled in a short time.
