EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to drawings.

Embodiment 1.

BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram which shows the evacuation support apparatus of the elevator by Embodiment 1 of this invention. In the figure, a plurality of elevator groups 1 are provided in a building (not shown). Each elevator group 1 has a plurality of elevators 2 having a plurality of floors as a service floor. Each elevator 2 has a car 3 which can be stopped on each service floor and an evacuation floor, and a control device 4 for controlling the movement of the car 3. In this example, the evacuation floor is the entrance floor where the entrance of the building is provided.

Each elevator group 1 is provided with a group management apparatus 5 for collectively managing the operation of each elevator 2. In addition, a platform call button 6 for registering a platform call is provided for each elevator 2 in each service floor and the evacuation floor. When the boarding point call is registered by the operation of the boarding point call button 6, the car 3 corresponding to the boarding point call among the cars 3 in the elevator group 1 is assigned by the group management apparatus 5 do.

Each floor of the building is provided with an emergency broadcast device (notification device) 7 for conducting announcements regarding evacuation guidance to the entire building. In addition, the building is provided with a central management room (disaster prevention center) for intensively monitoring and controlling facility equipment related to disaster prevention. In the central management room, a disaster prevention management device 8 that collectively manages disaster prevention equipment for the entire building, and an evacuation support device that collectively manages each group management device 5 in case of an emergency such as when a notice of terrorism occurs. (9) is provided.

The evacuation support device 9 collectively manages each group management device 5 to perform evacuation operation for each elevator group 1 for transporting the inspectors left in the building to the evacuation floor. The operation input information regarding evacuation operation is input to the evacuation support device 9 by the operation of an external input device (not shown) provided in the central management room. Evacuation operation is controlled based on the operation input information received by the evacuation support device 9.

As the external input device, a personal computer (PC) or the like is used, for example. In addition, the operation input information includes emergency information indicating the degree of urgency (for example, information on a scheduled time (limit time) of terror occurrence induced by the contents of the notice of terrorism). In addition, the external input device may be directly attached to the evacuation support device 9.

The evacuation support device 9 includes a communication unit 10, an evacuation driving unit 11, an evacuation driving time calculating unit 12, an evacuation driving determining unit 13, and a notification command unit 14.

The communication unit 10 performs information communication between each of the group management apparatus 5, the disaster prevention management apparatus 8, and the external input apparatus and the evacuation support apparatus 9, respectively.

The evacuation driving unit 11 outputs an instruction for evacuation operation to each group management device 5 to perform evacuation operation for each elevator 2. Evacuation operation is performed by setting at least one of each service floor to a rescue floor, and moving the cage | basket | car 3 between a rescue floor and an evacuation floor. When the landing call button 6 is operated at the landing of the rescue floor during the evacuation operation, the car 3 in response to the landing call is moved to the rescue floor by the control of the control device 4. The car 3, which has arrived at the rescue floor, is moved to the evacuation floor after the inspector boards.

In this example, the evacuation driving unit 11 sets all service layers as rescue floors. Thereby, each cage | basket | car 3 at the time of an evacuation operation becomes possible to land on all the service floors and evacuation floor. That is, the evacuation operation of each elevator is the same operation as the normal operation by normal control.

Evacuation operation time calculation part 12 receives operation input information from an external input device, and calculates for each elevator 2 the estimated time to continue evacuation operation based on operation input information as an evacuation operation time.

In this example, the evacuation driving time is calculated based on the information of the scheduled time of the terror occurrence. That is, evacuation driving time is calculated so that evacuation driving ends before the scheduled time (limit time) of the terror occurrence. Specifically, the calculation of the evacuation operation time for each elevator 2 is performed as follows.

First, each turn time is calculated for each elevator 2. With time for car 3, the car 3 leaves the evacuation floor, and the passengers left on each rescue floor are taken to the car 2 in turn, and after returning to the evacuation floor and completing the disembarkation of the visitors, the evacuation floor is restarted from the evacuation floor. One cycle time to departure.

Subsequently, the spare time T is calculated | required about each elevator 2 based on the winding time. For example, if the meeting time is less than 5 minutes, the spare time T = 5 minutes, and if the meeting time is longer than 5 minutes and less than 10 minutes, the spare time T = 10 minutes. After that, the evacuation operation time is calculated based on the allowable time T for each elevator 2. In this example, the evacuation operation time is calculated for each elevator 2 so that evacuation operation is terminated at an earlier time T minutes earlier than the scheduled time of the terror occurrence. Further, for example, a predetermined value such as T = 15 minutes may be set in advance as a spare time T minutes.

The evacuation operation determination unit 13 determines whether the evacuation operation for each elevator 2 is continued on the basis of the information from the evacuation operation time calculation unit 12. That is, the evacuation operation determination unit 13 determines that the evacuation operation can be continued for each elevator 2 when the time since the evacuation operation is started is within the evacuation operation time (continuity determination), and the evacuation operation is performed. When the time since the start has passed the evacuation operation time, it is determined that the evacuation operation for each elevator 2 is impossible (continuity determination).

The evacuation operation execution unit 11 controls the evacuation operation for each elevator 2 based on the information from the evacuation operation determination unit 13. That is, the evacuation driving unit 11 starts the evacuation operation for each elevator 2 when the evacuation driving determination unit 13 starts the determination of the possibility of continuing. In addition, the evacuation operation execution unit 11 continues the evacuation operation for each elevator 2 when the evacuation operation determination unit 13 is continuously performing the determination, and the evacuation operation determination unit 13 determines that the evacuation operation determination unit 13 cannot continue. When performed, the evacuation operation for each elevator 2 is terminated.

The notification command unit 14 controls each emergency broadcast apparatus 7 based on the information from the evacuation driving determination unit 13. That is, the notification command unit 14 outputs the evacuation notification command to each emergency broadcasting device 7 when the evacuation driving determination unit 13 is capable of continuing, and the evacuation driving determination unit 13 determines that the evacuation driving determination unit 13 cannot continue. Outputs an end notification command to each emergency broadcast apparatus 7 during the operation. In this example, command transmission from the notification command unit 14 to each emergency broadcast apparatus 7 is performed through the disaster prevention management apparatus 8.

Each emergency broadcast apparatus 7 informs the building that evacuation by the evacuation operation of each elevator 2 is possible by receiving an evacuation notification command. Moreover, each emergency broadcast apparatus 7 informs in a building that the evacuation operation of each elevator 2 is complete | finished by receiving the completion | finish notification command.

The evacuation support device 9 is configured by a computer having an arithmetic processing unit (CPU), a storage unit (ROM and RAM, etc.) and a signal input / output unit. The functions of the communication unit 10, the evacuation driving unit 11, the evacuation driving time calculating unit 12, the evacuation driving determining unit 13, and the notification command unit 14 are realized by a computer of the evacuation supporting apparatus 9. do.

That is, a program for realizing the functions of the communication unit 10, the evacuation operation execution unit 11, the evacuation operation time calculation unit 12, the evacuation operation determination unit 13, and the notification command unit 14 is stored in the storage unit of the computer. Is stored. In addition, information such as each rescue layer is also stored in the storage unit. The arithmetic processing unit executes arithmetic processing relating to the function of the evacuation support device 9 based on the program stored in the storage unit.

Next, the operation will be described. FIG. 2 is a flowchart for explaining the processing operation of the evacuation support device 9 of the elevator of FIG. As shown in the figure, for example, when a notice of terrorism is received, an external input device is operated by a watchman in the central management room, and operation input information including a limit time (urgent information), which is a scheduled time of terror occurrence, is external. It is input to the evacuation support apparatus 9 from an input apparatus (S1).

When operation input information from an external input device is input to the evacuation support device 9, the evacuation operation time is calculated by the evacuation operation time calculation unit 12 based on the limit time (S2). After that, the evacuation operation of each elevator 2 is performed by the control of the evacuation operation execution unit 11 (S3).

Thereafter, whether the evacuation operation time has elapsed is determined by the evacuation operation determination unit 13 (S4). If the evacuation operation time has not elapsed, the evacuation operation of each elevator 2 continues (S3). In this case, the evacuation notification command is output from the notification command unit 14 to each emergency broadcast apparatus 7. By this, it is known by the emergency broadcasting apparatus 7 in the building that the evacuation by the evacuation operation of each elevator 2 is possible.

On the other hand, when the evacuation operation time has elapsed, evacuation operation of each elevator 2 is terminated by the control of the evacuation operation execution unit 11. At this time, the cage | basket | car 2 is moved to an evacuation floor quickly, and is stopped normally with the door open. At this time, the termination notification command is output from the notification command unit 14 to each emergency broadcasting device 7 so that the evacuation operation of each elevator 2 is completed by the emergency broadcasting device 7. It is known in (S5).

Subsequently, when the inmates remain in the building, the inmates are guided by each emergency broadcasting device 7 and evacuated by, for example, stairs.

In such an evacuation assistance device of an elevator, the estimated time to continue evacuation operation is calculated as the evacuation operation time based on the emergency information indicating the degree of emergency, such as, for example, the scheduled time of the occurrence of terrorism, and is based on the calculated evacuation operation time. Therefore, it is determined whether the evacuation operation is continued, so that the evacuator can be efficiently transported to the evacuation floor in an emergency, and the evacuation of each elevator 2 before the operation of each elevator 2 abnormally increases. You can end the operation. Therefore, the abnormal stop of the evacuation operation of each elevator 2 can be prevented, for example, it can prevent that trapping in the cage | basket | car 3 of a reinspector arises.

In addition, when the evacuation operation determination unit 13 determines that the evacuation operation of each elevator 2 cannot be continued, the emergency broadcast apparatus 7 indicates that the evacuation operation of each elevator 2 ends. Since the inside of the building is notified, the end of the evacuation operation of each elevator 2 can be recognized by the inspector, and the panic occurrence after the evacuation operation can be prevented.

In the above example, in the evacuation operation of the elevator 2, all service floors are set to the rescue floor, and the same operation as the normal operation is performed, but for example, only a predetermined service floor preset among each service floor is the rescue floor. The operation of reciprocating the car 3 between the rescue floor and the evacuation floor may be an evacuation operation. In this case, the car 3 at the time of evacuation operation is stopped only in the rescue floor and the evacuation floor, and each floor other than the rescue floor and the evacuation floor passes. In addition, the inspector on the other floor of the rescue floor moves to the rescue floor by the stairs provided in the building in order to use the elevator 2. By doing in this way, the floor which stops the cage | basket | car 3 can be reduced, and the conveyance efficiency at the time of conveying the reinspector in a building to an evacuation floor can be aimed at.

In addition, the driving method of evacuation driving | operation is not limited to the said method, For example, what is necessary is just to set previously according to the shape of a building, a use, or the population of an attendant.

In the above example, the information on the scheduled time (limit time) of the terror occurrence included in the operation input information from the external input device may be input to the evacuation driving time calculation unit 12 as the emergency information, but the disaster prevention management device ( The information from 8) may be input to the evacuation operation time calculation unit 12 as the emergency information.

For example, when a fire breaks out in a building, the disaster prevention management apparatus 8 detects the presence or absence of a fire occurrence and specifies the fire generation floor based on information from a plurality of fire detectors provided on each floor of the building, The evacuation operation time calculation unit 12 may calculate the evacuation operation time based on the information from the disaster prevention management apparatus 8. In this case, the evacuation operation time calculation unit 12 calculates the combustion speed of the fire based on the information from the disaster prevention management apparatus 8 and calculates the evacuation operation time from the obtained combustion speed.

Even in this way, the evacuation operation of each elevator 2 can be terminated before the possibility that the operation of each elevator 2 stops abnormally becomes extremely high. Therefore, the abnormal stop of evacuation operation of each elevator 2 can be prevented, for example, it can prevent that a reinvestigator is trapped in the cage | basket | car 3, and generation | occurrence | production.

According to the present invention, it is possible to provide an elevator evacuation support apparatus capable of preventing abnormal stop of evacuation operation of the elevator.
