Detailed ways

Preferred embodiments of the present invention will be described below with reference to the drawings.

first embodiment

Fig. 1 is a block diagram showing an evacuation management device for an elevator according to a first embodiment of the present invention. In the figure, a plurality of elevator groups 1 are installed in a building (not shown). Each elevator group 1 has a plurality of elevators 2 serving a plurality of floors. Each elevator 2 has a car 3 that can stop at each service floor and evacuation floor, and a control device 4 that controls the movement of the car 3 . In this example, the lobby floor where the lobby of the building is installed is used as the evacuation floor.

Each elevator group 1 is provided with a group management device 5 for collectively managing the operation of each elevator 2 . Furthermore, a hall call button 6 for registering a hall call is provided for each elevator 2 on each service floor and evacuation floor. When a hall call is registered by operating the hall call button 6 , the car 3 that responds to the hall call among the cars 3 in the elevator group 1 is assigned by the group control device 5 .

Each floor of the building is provided with a fire detector 7 for detecting the occurrence of a fire and an emergency broadcasting device 8 for broadcasting notifications about evacuation to the entire building in case of emergency. Information from each fire detector 7 is transmitted to a disaster prevention management device 9 that collectively manages disaster prevention facilities in the entire building. The disaster prevention management device 9 detects whether or not a fire has occurred based on information from each fire detector 7 and specifies the floor where the fire occurred.

The information from the disaster prevention management device 9 is transmitted to the management device 10 for collectively managing the evacuation of each group of management devices 5 when a fire occurs. After the fire occurrence is detected by the disaster prevention management device 9, the evacuation time management device 10 performs an evacuation operation for each elevator group 1 to transport occupants staying in the building to the evacuation floor. Furthermore, the disaster prevention management device 9 and the evacuation time management device 10 are installed in a management room (disaster prevention center) for centralized monitoring and control of disaster prevention-related equipment.

The evacuation management device 10 has a communication unit 11 , an evacuation operation execution unit 12 , a determination unit 13 , and an evacuation operation restart unit 14 .

The communication unit 11 performs information communication between each group management device 5 and disaster prevention management device 9 and the evacuation time management device 10 .

The evacuation operation implementation unit 12 executes the evacuation operation for each elevator 2 by outputting an evacuation operation command to each group control device 5 . The evacuation operation is performed by setting at least one of the service floors as a rescue floor and moving the car 3 between the rescue floor and the evacuation floor. When the hall call button 6 is operated at the hall of the rescue floor during the evacuation operation, the car 3 that responds to the hall call moves to the rescue floor under the control of the control device 4 . The car 3 that has arrived at the rescue floor moves to the refuge floor after the people in the building board.

In this example, the evacuation operation execution unit 12 sets all service floors as rescue floors. Accordingly, each car 3 during the evacuation operation can stop at all service floors and evacuation floors. That is, the evacuation operation of each elevator is the same operation as the normal operation under the control at the normal time.

The determination unit 13 determines whether or not the evacuation operation for each elevator group 1 is possible based on information from the disaster prevention management device 9 and the evacuation operation execution unit 12 , respectively. That is, the determination unit 13 determines whether or not the evacuation operation for each elevator group 1 is possible based on the positional relationship between each rescue floor and the fire occurrence floor.

And, the determination unit 13 determines whether or not the evacuation operation can be terminated for each elevator group 1 based on the information from each elevator group 1 . That is, when the evacuation operation satisfies the predetermined end condition obtained from the information from each elevator group 1, the determination unit 13 determines that the evacuation operation is completed (performs the operation end judgment), and when the evacuation operation does not satisfy In the case of a predetermined end condition, the determination unit 13 determines to continue the evacuation operation (performs an operation continuation determination). The evacuation operation of the elevator group 1 is completed when the determination unit 13 has made a termination determination, and the evacuation operation of the elevator group 1 is continued when the determination unit 13 has performed a continuation determination.

As the situation of satisfying the prescribed end condition, for example, the following situations can be mentioned: the state where the boarding detection sensor (such as a weighing device, etc.) used to detect the boarding of the elevator 2 stops the detection of the boarding, or the boarding at all rescue floors. When the generation of hall calls stopped due to the operation of the hall call button 6 continues for a predetermined time; when the end button installed in each elevator group 1 is operated; or due to the spread of fire and firefighting activities The abnormality detection sensor installed in each elevator group 1 is activated due to flooding caused by it, and the like. That is, when it is difficult to continue the evacuation operation or when the evacuation operation end condition is satisfied, it is considered that the predetermined end condition is satisfied.

Here, a restart switch (manual switch) 15 for restarting the completed evacuation operation is provided on the evacuation time management device 10 . The restart switch 15 can be manually operated in the management room. Information from the restart switch 15 is transmitted to the evacuation operation restart unit 14 through the communication unit 11 .

After the evacuation operation has ended according to the determination of the end of operation by the determination unit 13, the evacuation operation restart unit 14 determines whether or not to resume the operation for each elevator group 1 based on information from each elevator group 1, the determination unit 13, and the restart switch 15. Evacuation operation. That is, after the evacuation operation is completed, when the predetermined restart condition obtained based on the information from each elevator group 1, the determination unit 13 and the restart switch 15 is satisfied, the evacuation operation restart unit 14 determines that The evacuation operation is restarted (operation restart determination is performed), and when the predetermined restart condition is not satisfied, it is determined that the end of the evacuation operation is continued (termination continuation determination is performed). The evacuation operation of the elevator group 1 is resumed when the evacuation operation resumption unit 14 performs the operation resumption determination, and the evacuation operation of the elevator group 1 is continued when the evacuation operation resumption unit 14 performs the end continuation determination.

As the case where the predetermined restart condition is satisfied, for example, the following cases can be mentioned: the evacuation operation can be implemented and the detection of the boarding by the boarding detection sensor occurs or the emergency call button 6 is operated at the rescue floor. A case where a landing call occurs; or a case where an evacuation operation can be performed and the restart switch 15 is operated, etc. That is, when the evacuation operation is possible and the presence of people in the building is detected, it is considered that the predetermined restart condition is satisfied.

The management device 10 at the time of evacuation is constituted by 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 11 , the evacuation operation execution unit 12 , the determination unit 13 , and the evacuation operation restart unit 14 are realized by the computer of the evacuation time management device 10 .

That is, programs for realizing the functions of the communication unit 11 , the evacuation operation execution unit 12 , the determination unit 13 , and the evacuation operation restart unit 14 are stored in the storage unit of the computer. In addition, information on each rescue floor and the like is also stored in the storage unit. The arithmetic processing unit executes arithmetic processing related to the functions of the management device 10 at the time of evacuation based on the program stored in the storage unit.

Next, the operation will be described. FIG. 2 is a flowchart for explaining processing operations of the evacuation management device in FIG. 1 . As shown in the figure, when the occurrence of a fire is confirmed by the disaster prevention management device 9 (S1), the confirmation information of the fire occurrence is transmitted from the disaster prevention management device 9 to the evacuation time management device 10. Then, the control operation command is output from the management device 10 at the time of evacuation to each group control device 5, and the operation of each elevator group 1 becomes the control operation at the time of fire. The control operation in case of fire is an operation in which the moving car is parked at the nearest floor and the door is opened to stand by (S2).

Thereafter, each rescue floor is set by the evacuation operation execution unit 12, and the evacuation operation for each elevator group 1 is executed (S3). Then, whether or not a predetermined end condition is satisfied is judged by the judging unit 13 . That is, the judging unit 13 executes a judgment as to whether it is difficult to continue the evacuation operation and a judgment as to whether the end condition of the evacuation operation is satisfied ( S4 ).

When it is determined that the predetermined end condition is not satisfied, the determination unit 13 performs an operation continuation determination to continue the evacuation operation. When it is judged that the predetermined end condition is satisfied, the judgment unit 13 makes an operation end judgment, and ends the evacuation operation (S5).

Then, the evacuation operation restart unit 14 judges whether or not predetermined restart conditions are satisfied. That is, the evacuation operation restart unit 14 determines whether the evacuation operation can be performed and whether the presence of people in the building is detected ( S6 ).

When it is determined that the predetermined restart condition is satisfied, the evacuation operation restart unit 14 performs an operation restart determination, and restarts the evacuation operation. When it is determined that the predetermined restart condition is not satisfied, the end state of the evacuation operation is continued.

In such an evacuation management device for an elevator, since the evacuation operation is restarted when the predetermined restart condition is satisfied after the evacuation operation is completed, even if there are still people in the building after the evacuation operation is completed, The occupants of the building can be transported from the rescue floor to the evacuation floor by the evacuation operation after the restart. Thereby, it is possible to improve the transport efficiency when transporting occupants in the building to the evacuation floor.

In addition, when at least one of the state in which the detection of the boarding elevator 2 is stopped and the generation of hall calls at all rescue floors is stopped for a predetermined time, the predetermined end condition is satisfied. Therefore, it is possible to avoid unnecessary evacuation operation after there are no people in the building, and to prevent the occurrence of adverse situations (such as unnecessary consumption of electric power and elevator failure, etc.) caused by continuation of evacuation operation.

In addition, when at least one of the landing call on the elevator 2 and the rescue floor is detected, and the evacuation operation can be performed, it is considered that the specified restart condition is satisfied, so even if people move in the building relatively In the case that the elevator arrives at the landing on the rescue floor after the evacuation operation has ended, the occupants of the building can also restart the evacuation operation in this case. Therefore, it is possible to further improve the transport efficiency when transporting occupants in the building to the evacuation floor.

In addition, since the restart switch 15 that can be manually operated is provided in the management room of the building, when the restart switch 15 is operated and the evacuation operation can be implemented, it is considered that the specified restart condition is met, so it is possible to pass through the management room. The monitor operates the restart switch 15 to restart the completed evacuation operation. For example, if a camera (camera) is installed at the landing on the rescue floor and a monitor is installed in the management room to show images captured by the camera, the images of people in the building may also be displayed on the monitor after the evacuation operation is completed. . In addition, there are cases where a firefighter or the like discovers a person in the building and contacts the surveillance personnel in the management room. At this time, since the evacuation operation can be restarted by the operation in the management room, and the occupants of the building can be transported to the evacuation floor, it is possible to further improve the transportation efficiency when transporting the occupants of the building to the evacuation floor.

In addition, in the above-mentioned example, regarding the evacuation operation of the elevator 2, all the service floors are set as rescue floors, and the operation is the same as that of the normal operation. The predetermined service floor set in advance is used as the rescue floor, and the car 3 is reciprocated between the rescue floor and the evacuation floor. At this time, the car 3 during the evacuation operation stops only at the rescue floor and the evacuation floor, and passes through all floors between the rescue floor and the evacuation floor. In order to use the elevator 2, the people in the building on the floors other than the rescue floor need to go to the rescue floor by the stairs arranged in the building. In this way, the number of floors on which the car 3 stops can be reduced, and it is possible to further improve the transport efficiency when transporting occupants in the building to the evacuation floors.

In addition, the operation method of the evacuation operation is not limited to the above method, and may be set in advance according to the shape of the building, its purpose, or the number of people in the building, for example.
