Description

Elevator equipment

This invention relates to an elevator apparatus, and more particularly to a system for performing an evacuation operation during an emergency evacuation such as a fire.

In the conventional elevator system, when a fire is detected, the car is moved to a floor designated in advance and the operation is stopped. Thereafter, when the firefighter arrives at the building, the firefighter confirms the state of the fire and gets into the car, and operates the dedicated rescue operation car switch to evacuate the car (for example, see Patent Document 1). ).

JP 2005-112601 A

In the conventional elevator apparatus as described above, it takes time until the evacuation operation is completed because the fire fighter performs the evacuation operation in the car after the firefighter arrives at the building.

The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator apparatus that can evacuate people in a building more efficiently during an emergency evacuation.

The elevator apparatus according to the present invention is provided in an elevator controller that controls the operation of a car that is raised and lowered on a hoistway, and at least one landing, and an evacuation operation command signal for evacuating the car is input. The elevator controller is provided with operation input means, and evacuates the car according to an evacuation operation command signal from the evacuation operation input means during emergency evacuation.

The elevator apparatus according to the present invention is provided with at least one evacuation operation input means to which an evacuation operation command signal for evacuating a car is input, and the elevator controller receives an evacuation operation command from the evacuation operation input means during emergency evacuation. Because the car is evacuated according to the signal, during emergency evacuation, it is possible to control the evacuation operation personally by operating the fire prevention officer at the landing and to evacuate other waiting passengers with priority. The people inside can be evacuated more efficiently.

BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram which shows the elevator apparatus by Embodiment 1 of this invention. It is a flowchart which shows the evacuation procedure at the time of emergency using the elevator apparatus of FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
In this embodiment, a building evacuation method using an elevator apparatus in an emergency such as a building fire is disclosed. This evacuation method is controlled by a Fire Warden (FW) designated in advance. In the event of a fire emergency that requires evacuation from the entire building or a part of the building, the fire prevention officer controls the elevator device to execute the evacuation operation.

Usually, there are one or more fire officers in a building. Fire managers are persons who work or live in the building (depending on the type of building) and have received some training in emergency situations.

FIG. 1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, a hoisting machine 1 is installed at the upper part of the hoistway. The hoist 1 includes a drive sheave 2, a hoist motor that rotates the drive sheave 2, and a hoist brake that brakes the rotation of the drive sheave 2.

The suspension means 3 is wound around the drive sheave 2. As the suspension means 3, a plurality of ropes or a plurality of belts are used. The car 4 and the counterweight 5 are suspended by the suspension means 3 and are raised and lowered in the hoistway by the hoisting machine 1.

The operation of the hoisting machine 1 is controlled by an elevator controller 6. That is, the operation of the car 4 is controlled by the elevator controller 6. As the elevator controller 6, a microcomputer including a memory 7 is used.

The car 4 is provided with a car operation panel (COP) 9 and a utilization rate detecting means 10 for investigating the utilization rate in the car 4. As the utilization rate detecting means 10, for example, an optical sensor that optically detects the usage state in the car 4, a scale device that detects the usage state in the car 4 by weight, or the like is used.

The car operation panel 9 is provided with a plurality of destination floor buttons 13, an in-car speaker 14, an evacuation floor button (evacuation floor switch) 15, and a bypass key switch 16. The functions of the evacuation floor button 15 and the bypass key switch 16 will be described later.

The hall door device 11 and the hall operation panel 12 are provided at the hall on each floor. The hall operation panel 12 is provided with a pair of upper and lower hall buttons 17, a hall speaker 18, and an FW control key switch 19 as evacuation operation input means.

The FW control key switch 19 can be input only by the fire supervisor. In the event of an emergency in which the operation mode of the elevator apparatus is switched to the evacuation mode, the fire prevention officer comes to the landing and uses the FW control key switch 19 to control the evacuation operation by the elevator apparatus.

Next, FIG. 2 is a flowchart showing an evacuation procedure in an emergency using the elevator apparatus of FIG. When a fire is detected by a fire sensor or a smoke sensor provided in the building, a signal is immediately input from the sensor to the elevator controller 6 (step S1). When the information about the presence of fire in the building is obtained, the operation mode of the elevator apparatus is automatically switched to the evacuation mode (step S2). Alternatively, if the building has a 24-hour monitoring system, switching to evacuation mode can be done manually by the building manager.

When the driving mode is switched to the evacuation mode, all car calls and hall calls are erased (step S3), and voice announcement information regarding the evacuation mode is given to passengers waiting at the hall (step S4).

Subsequently, the car 4 is moved to a designated evacuation floor (for example, the entrance floor of the building) without stopping at any other floor (step S5). For example, when the car 4 is moving upward above the evacuation floor, the car 4 is first decelerated, stopped with the door closed, and then started to run downward until the evacuation floor. Moved.

When the car 4 arrives at the evacuation floor, the car door device and the landing door device 11 are opened, and a voice instruction is given to the passenger to leave the car 4 and follow further instructions from the staff (building manager, fire officer or firefighter). Is given (step S6). Such voice instructions are given to passengers in the car 4 via the car speaker 14.

When the fire prevention officer hears the fire alarm, he / she comes to the landing, inserts a key into the FW control key switch 19, and inputs an evacuation operation command signal for causing the car 4 to evacuate (step S21). The elevator controller 6 evacuates the car 4 in response to an evacuation operation command signal from the hall operation panel 12 during emergency evacuation. Further, the elevator controller 6 moves the car 4 between the floor where the evacuation operation command signal is input and the evacuation floor as the evacuation operation in response to the input of the evacuation operation command signal.

Note that the evacuation operation input means is not limited to the FW control key switch 19, and may be, for example, a card reader that reads information on an ID card, a code reader that reads codes, or other identification means.

When two or more persons in charge of fire prevention use the FW control key switch 19 at different landings, that is, there are cases where evacuation operation is applied from the FW control key switches 19 at two or more landings. In this case, the elevator controller 6 validates only the evacuation operation command signal from the FW control key switch 19 to which the evacuation operation is first applied (step S22).

In this case, the elevator controller 6 stores another evacuation operation offer in the memory 7 (step S23). Thereby, the elevator controller 6 can validate the next FW control key switch 19 in the order of the request for evacuation operation, when control of the evacuation operation is canceled by the activated FW control key switch 19.

When the evacuation operation offer (call) is stored in the memory 7, the fire protection officer obtains some feedback from the elevator controller 6 (step S24). Further, when an evacuation operation is carried out by a fire prevention officer on another floor, voice information to that effect is given from the hall speaker 18 to the waiting passengers at the hall.

The elevator controller 6 checks whether the car 4 is unattended on the evacuation floor by using the utilization rate detecting means 10 after being called by the fire prevention supervisor (step S7). At this time, the car 4 can be regarded as unmanned by opening the door for a certain period of time (a time sufficient for all passengers to get out of the car 4) and then closing the door. In this case, it is preferable to announce from the in-car speaker 14 audio information for notifying the door closing while the door is open.

If it is determined that the evacuation operation command signal is activated and the car 4 is unmanned, the elevator controller 6 moves the car 4 to the landing (the first called floor) where the evacuation operation command signal is input (step S8). ).

When the car 4 arrives at the boarding area, the fire prevention officer helps the resident to get into the car 4 and adjusts all evacuation procedures (step S9). The fire supervisor directs the passengers what action to take in an emergency. In addition, the fire manager determines the order of residents to evacuate.

After this, the fire protection officer checks whether there is room for passengers in the car 4 (step S10). If there is no room left in the car 4, the person responsible for fire prevention uses the FW control key switch 19 (that is, by sending a pulse) to give a command signal for preferentially directing the car 4 to the evacuation floor. 6 As a result, all other calls are bypassed, and the car 4 goes straight to the evacuation floor without stopping at any other floor (step S12).

This priority function saves valuable evacuation time which is very important in case of emergency. Further, this priority function can be given to the elevator controller 6 only from the landing where the evacuation operation command signal is validated, and becomes active only in the evacuation mode.

When the priority function is activated, the waiting customer at the hall is informed about this function by voice instruction (step S13). This voice instruction is given through the hall speaker 8. Further, by giving information about the waiting time to the waiting customer at the landing as a voice instruction, the waiting customer's panic can be reduced.

When the car 4 arrives at the evacuation floor, all passengers get off the car 4 (step S14). Then, after checking whether the car 4 is unmanned (step S7), the car 4 is returned to the calling floor again (step S8).

When the car 4 is not full and the floor to be evacuated becomes unmanned, the fire supervisor removes the key from the FW control key switch 19 and cancels the elevator control by the fire supervisor (step S15). This prepares another fire manager from another floor to control the elevator.

Next, the fire prevention officer gets into the car 4. In the car 4, the fire prevention person in charge presses the evacuation floor (EV) button 15 on the car operation panel 9 (step S <b> 16). In addition, when the person in charge of fire control controls the elevator by registering the code in the code reader at the landing, there is another keypad in which the person in charge of fire prevention can register another code in order to cancel the control of the elevator. Should be provided within.

After this, the car 4 starts to go to the evacuation floor (step S17). In this case, the car 4 can respond to calls from other landings in the direction of the evacuation floor, stops at that landing, and collects several more passengers (step S18). The evacuation floor button 15 is active only when the elevator apparatus is operating in the evacuation mode. Alternatively, this may be a main lobby button that switches to an evacuation floor button when the elevator apparatus is operating in evacuation mode.

If another call from the landing is received while the car 4 is moving toward the evacuation floor, the elevator controller 6 first checks the utilization rate of the car 4 using the utilization rate detecting means 10 (step S19). ). If there is still room for another passenger in the car 4, the car 4 is stopped at the calling floor (step S8). If there is no room in the car 4, the car 4 is moved directly to the evacuation floor (step S20), and the elevator is unmanned on the evacuation floor and then moved to the calling floor (step S8).

The car 4 can be moved directly to the evacuation floor by operating the bypass key switch 16 instead of the utilization rate detecting means 10. The person in charge of fire prevention operates the bypass key switch 16 when there is no room in the car 4.

When the car 4 arrives at the evacuation floor, the door is opened, and a voice instruction is announced to the passenger to go out from the car 4 to the evacuation floor. Voice instructions are given through the car speaker 14. When the car 4 is unattended, the car 4 is sent to the floor where the fire officer is waiting for the car 4 to return.

”Evacuation operation at each floor is repeated until evacuation from that floor is completed (in the case of an elevator dedicated to evacuation of the disabled, until the evacuation of the disabled is completed). When the evacuation operation on one floor is completed, the person in charge of fire prevention uses the FW control key switch 19 again to deactivate the function and enter the car 4. Then, it becomes possible to carry out evacuation operation by another person in charge of fire prevention.

In such an elevator apparatus, an FW control key switch 19 to which an evacuation operation command signal for evacuating the car 4 is input is provided in at least one landing, and the elevator controller 6 is connected to the FW control key switch 19 during emergency evacuation. Because the car 4 is evacuated in response to the evacuation operation command signal, the evacuation operation is personally controlled by the person in charge of fire prevention at the landing during emergency evacuation, and other waiting passengers are given priority to evacuate It is possible to evacuate residents in the building more efficiently. In addition, the system can be given more flexibility and the confidence among evacuees can be increased.

In addition, after investigating whether the car 4 is unmanned, the car 4 is moved to the landing where the evacuation operation command signal is input, so that more waiting customers can be moved from the calling floor to the evacuation floor. Residents in the building can be evacuated more efficiently.

Further, when the elevator controller 6 inputs cancellation of the evacuation operation control on the hall operation panel 12, the elevator controller 6 waits for the evacuation floor button 15 to be operated and moves the car 4 to the evacuation floor. After confirming the evacuation of waiting customers on that floor, he can get on the car 4 and evacuate himself.

Furthermore, since the FW control key switch 19 can be input only by the fire supervisor, the evacuation operation can be performed safely only by the fire supervisor.

Further, when an evacuation operation is requested from the FW control key switches 19 at two or more halls, the elevator controller 6 validates only the evacuation operation command signal from the FW control key switch 19 to which the evacuation operation is first applied. Therefore, the evacuation operation can be started earlier and the time required for evacuation can be shortened.

Further, the elevator controller 6 validates the evacuation operation command signal from the next FW control key switch 19 when the cancellation of the control is input by the activated FW control key switch 19, so that the evacuation of a certain floor is performed. The evacuation operation of the next floor can be started immediately after the operation is completed, and the time required for evacuation can be shortened.

Further, the elevator controller 6 investigates the available space in the car 4 while moving the car 4 to the evacuation floor after the cancellation of the control is input by the FW control key switch 19, and Depending on whether the car 4 is to go straight to the evacuation floor or whether the car 4 is stopped at the landing of the FW control key switch 19 to be activated next, the space in the car 4 is used efficiently, More people can be evacuated by driving, and the time required for evacuation can be shortened.

In addition, when the car 4 arrives at the evacuation floor, a voice instruction prompting the user to leave the car 4 is announced from the speaker 14 in the car, so that the car 4 can be departed to the next calling floor at an earlier stage. The time required can be shortened.

It should be noted that some functions of the elevator apparatus according to the first embodiment can be used other than during emergency evacuation.
For example, the FW control key switch 19 can be used in a special case where priority is given to the emergency car 4 such as a hospital elevator.

Also, the bypass key switch 16 is an elevator dedicated to a disabled person in a special building, and can be used when there is a call waiting even though there is no room in the car 4. In this case, the hall speaker 8 may be used in combination with the bypass key switch 16 to convey information about the waiting time to the waiting passengers at the hall. The fact that there is no room in the car 4 can also be detected by the utilization rate detecting means 10.

Further, in the above example, the FW control key switch 19 is provided on the hall operation panel 12, but it may be provided at a place different from the hall operation panel 12.
Furthermore, the evacuation operation input means may be provided at the landings of all the floors, or may be provided only at the landings of one or more floors selected in advance.
Further, although the 1: 1 roping elevator apparatus is shown in FIG. 1, the roping system is not limited to this, and the present invention can be applied to, for example, a 2: 1 roping elevator apparatus.
Furthermore, the layout of the elevator equipment (the number and position of the hoist 1 and the counterweight 5) is not limited to the example shown in FIG.
Furthermore, the present invention can be applied to a machine room-less elevator having no machine room and various types of elevator apparatuses.
