Embodiment 1 FIG.
In this embodiment, a building evacuation method using an elevator in an emergency such as a building fire and a configuration necessary for evacuation using an elevator apparatus are disclosed. This evacuation method is controlled by a lift attendant (LA) designated in advance. In the event of a fire emergency that requires evacuation from the entire building or part of the building, the elevator clerk controls the elevator device from within the car to perform evacuation operation.

  A building typically has one or more elevator personnel (LA). An elevator clerk is a person who works or resides in a building (depending on the type of building) and has received some training in emergency situations.

  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.

  A 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 hoist 1 is controlled by the 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 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.

  A landing door device 11 and a landing operation panel 12 are provided at the landing on each floor. In the building, an evacuation floor and one or more designated floors (DF: Designated Floor) are set in advance. For this reason, the hall includes at least one designated floor hall, an evacuation floor hall, and another floor hall that is a hall excluding the designated floor hall and the evacuation floor hall. In FIG. 1, these are shown one by one for simplicity.

  FIG. 2 is an enlarged front view showing the hall operation panel 12 of the designated floor hall shown in FIG. The hall operation panel 12 includes a pair of upper and lower hall buttons 13, a plurality (three in this case) of physically disabled buttons 14, a speaker 15 with a hall microphone, a hall intercom operation button 16, and a hall monitoring device (monitor). 17, a landing camera 18, a display device 19, and a landing LA control key switch 20 as a car call input means during evacuation.

  The landing button 13 is operated to register a call. The disabled person button 14 is operated to register additional information by the disabled person. That is, by selecting and operating one of the physically disabled buttons 14, additional information related to the disorder is registered. In this example, it is registered as additional information that the call is made by a wheelchair user, a hearing impaired person, or a visually impaired person.

  By using the speaker 15 with the landing microphone and the landing intercom operation button 16, communication between the passenger at the landing and the elevator staff in the car 4 is established.

  The hall LA control key switch 20 allows only the elevator staff to input a designated floor movement command signal for calling the car 4 to the designated floor hall. In an emergency situation in which the operation mode of the elevator apparatus is switched to the evacuation mode, the elevator clerk comes to the designated floor landing and moves the car 4 to the designated floor landing using the landing LA control key switch 20.

  The hall LA control key switch 20 is provided only on the hall operation panel 12 of the designated floor hall. The configuration of the landing operation panel 12 for the evacuation floor landing and the other floor landing is the same as the configuration in which the landing LA control key switch 20 is removed from the landing operation panel 12 for the designated floor landing.

  In this embodiment, an evacuation operation for evacuating a disabled person with priority by an elevator device in an emergency situation is performed. For this reason, when the operation mode is switched to the evacuation mode, the display device 19 displays a notice that the elevator device is dedicated to the disabled.

  FIG. 3 is an enlarged front view showing the car operation panel 9 of FIG. The car operation panel 9 includes a plurality of destination floor buttons 21, a speaker 22 with a car microphone, a car interphone operation button 23, an interphone selection button 24, a car monitoring device (monitor) 25, a car camera 26, and a body. A disabled person call indicator 27, a car LA control key switch 28 as an evacuation operation input means, and an evacuation floor button (evacuation floor switch) 29 are provided.

  Only the elevator clerk can input the evacuation operation command signal to the car LA control key switch 28. In an emergency situation in which the operation mode of the elevator apparatus is switched to the evacuation mode, the elevator staff gets into the car 4 and controls the evacuation operation by the elevator apparatus using the car LA control key switch 28.

  By using the speaker 22 with the car microphone and the car interphone operation button 23, communication between the elevator clerk in the car 4 and the passenger at the landing is established. Further, by operating the intercom selection button 24, it is possible to select the floor that the elevator clerk wants to communicate with.

  On the car monitoring device 25, a video of the landing taken by the landing camera 18 is displayed. On the hall monitoring device 17, an image in the car 4 taken by the car camera 26 is displayed.

  The disabled person call indicator 27 includes a plurality of LEDs (disabled person signs) for displaying additional information (disabled type) of calls by disabled persons. These LEDs are arranged in a matrix corresponding to the floor number and additional information. When the disabled button 14 is operated at the landing, the LED corresponding to the operated disabled button 14 is lit or blinked.

  4-7 is a flowchart which shows the evacuation procedure at the time of emergency using the elevator apparatus of FIG. The evacuation procedure of FIGS. 4-7 has two parts. That is, the part shown to FIGS. 4-6 is an automatic control part by the escape operation algorithm of the elevator controller 6. FIG. Moreover, the part shown in FIG. 7 is a manual control part which is controlled by special control means after the elevator clerk gets into the car 4.

  First, in FIG. 4, when a fire is detected by a fire detector or smoke detector provided in the building, a signal is immediately input from the detector 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 operation mode is switched to the evacuation mode, an audio announcement regarding the emergency situation is given to the waiting customer at the landing via the speaker 15 with the landing microphone (step S3). At the designated floor hall, the “designated floor” sign is turned on (step S4). Thereby, the elevator staff can grasp the designated floor that can be controlled by calling the car 4.

  Further, when the driving mode is switched to the evacuation mode, all car calls and landing calls are deleted (step S5), and an audio announcement regarding the emergency situation is given to passengers in the car 4 via the speaker 22 with the car microphone ( Step S6). Furthermore, all destination floor buttons 21 on the car operation panel (COP) 9 are invalidated (step S7), and all car calls from the landing are ignored (step S8).

  However, additional information, such as new calls and input regarding the passenger's disability type from the landing, is registered and stored in the memory 7 (step S9). When the disabled person button 14 is operated at the landing, the corresponding part of the disabled person call indicator 27 in the car 4 starts to light up or blink.

  The waiting customer who operates the handicapped person button 14 is given feedback regarding the call (step S10). Examples of feedback include generation of sound (for example, click sound), lighting of LED, or a combination thereof.

  Next, in FIG. 5, when the elevator clerk hears the fire alarm, he / she comes to the designated floor landing, inserts a key into the landing LA control key switch 20, and designates a designated floor movement command for calling the car 4 to the designated floor landing. Input the signal.

  The car call input means for evacuation is not limited to the landing LA control key switch 20, and may be, for example, a card reader for reading information on an ID card, a code reader for reading a code, or other identification means. Good.

  When the designated floor movement command signal is input, the elevator controller 6 checks the presence / absence of passengers in the car 4 based on the signal from the utilization rate detecting means 10 (step S11). If there is at least one passenger in the car 4, the car 4 is moved to a pre-designated evacuation floor (for example, the entrance floor of the building) without stopping at any other floor (step of the building) S12). 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, a voice announcement is given to the passenger to leave the car 4 (step S13). Such a voice instruction is given to passengers in the car 4 through the speaker 22 with the car microphone.

  Thereafter, the car door device and the landing door device 11 are opened (step S14), and the vehicle waits on the evacuation floor until the car 4 becomes unmanned (steps S15 and S16). When the car 4 becomes unattended, the car 4 is moved to the designated floor.

  Here, in a building in which two or more designated floors are set, one of them is preset as the first designated floor (DF1), and the other designated floor is the second designated floor (DF2). And

  The elevator controller 6 automatically moves the car 4 to the first designated floor when the inside of the car 4 is unattended and there is no call from any designated floor (step S18). Further, when the car 4 is unmanned and there is a call from the second designated floor (DF2), the elevator controller 6 moves the car 4 to the second designated floor (step S19). Further, when the operation mode is switched to the evacuation mode, the elevator controller 6 bypasses Steps S12 to S17 when the interior of the car 4 is unattended and there is no call from any designated floor. Is moved to the first designated floor (step S18).

  When the car 4 arrives at the designated floor, the car door device and the landing door device 11 are opened (step S20), and the system waits until the elevator clerk gets into the car 4 (step S21). Further, during the standby on the designated floor, it is monitored whether or not a call from the second designated floor is generated (step S22). If there is a call from the second designated floor while waiting on the first designated floor without a call from any designated floor, the elevator controller 6 will move the car to the second designated floor where the call has occurred. 4 is moved (step S19).

  After getting into the car 4, the elevator clerk inserts a key into the car LA control key switch 28, and inputs an evacuation operation command signal for causing the car 4 to evacuate (step S23). Thereby, the control of the evacuation operation is activated, and the operation of the car 4 is completely controlled by the elevator staff. This control is active until the elevator clerk deactivates the control function with the same car LA control key switch 28 at the end of the evacuation process (step S30).

  The evacuation operation input means is not limited to the car LA control key switch 28 like the evacuation car call input means. For example, the card reader for reading information on the ID card, the code reader for reading codes, or Other identification means may be used.

  Next, in FIG. 6, after the elevator clerk has completely controlled the operation of the car 4, all calls and additional information stored in the memory 7 are displayed on the car operation panel 9 (step S24). Further, the state of the car 4 is reported to the passengers at the landing (step S25). Further, the destination floor button 21, the evacuation floor button 29, and the staff communication system (interphone system) on the car operation panel 9 are activated (steps S26 to S28).

  The staff communication system includes a speaker 22 with a car microphone, a car interphone operation button 23, an interphone selection button 24, a speaker 15 with a hall microphone, and a hall interphone operation button 16. The evacuation floor button 29 and the clerk communication system are activated after the elevator clerk fully controls the operation of the car 4.

  Next, in FIG. 7, when the passenger at the landing calls the car 4, the corresponding destination floor button 21 is turned on or starts blinking (step S33). As a result, the elevator clerk notices the call. Further, when the passenger at the landing is a disabled person, the disabled person button 14 is pressed. Then, the LED corresponding to the disabled person call indicator 27 on the car operation panel 9 is turned on or starts blinking.

  At this point, the elevator clerk can communicate with the passengers at the landing via the clerk communication system (step S34). Based on at least one of the state of the disabled person call indicator 27 and the communication with the passenger, the elevator clerk determines whether the passenger is disabled (step S35).

  Since this elevator apparatus is exclusively for evacuation of physically handicapped persons, passengers who are not handicapped persons who can use the stairs are instructed to evacuate by using the stairs (step S36). Thus, healthy passengers evacuate using the stairs.

  If the passenger who registered the call is a disabled person, the elevator clerk makes a plan, moves the car 4 to the call floor, and picks up the passenger (step S37). At this time, if the car 4 is full or there is no room in the car 4, the elevator clerk uses the evacuation floor button 29 to move the car 4 to the evacuation floor without stopping any other floors. Directly send (step S39).

  When moving the car 4 to the evacuation floor, it is reported to the waiting customer at the landing that the car 4 is heading directly to the evacuation floor and can be used after being unattended on the evacuation floor (step S40).

  After getting the passengers off the evacuation floor (step S41), the elevator clerk confirms whether a new call is displayed (step S42). If the call is displayed, the car 4 is moved to the next call floor and the passengers on that floor are collected (step S37).

  The above process is repeated until the evacuation from the entire building or part of the building (in the case of partial evacuation) is completed. When all the passengers are evacuated and there is no waiting car call, the elevator clerk operates the car LA control key switch 28 to end the evacuation (step S43).

  Returning to FIG. 6, when the control of the evacuation operation by the elevator clerk is deactivated (step S30), the car 4 is in a use stop state with the door open on the evacuation floor (step S31). Then, the state of the car 4 is displayed at all landings (step S32).

  In such an elevator apparatus, the elevator clerk in the building can move the car to a designated floor during an emergency evacuation, and the elevator clerk can control the elevator controller 6 to cause the car 4 to evacuate. Therefore, the evacuation operation can be started earlier, and the evacuation operation can be personally controlled to evacuate people in the building more efficiently.

  Further, by controlling the evacuation operation by the elevator staff, further flexibility can be given to the evacuation operation, increasing the reliability of passengers and reducing the panic that is likely to occur in an emergency. For example, it is possible to evacuate a child or an elderly person with an elevator device according to the judgment of an elevator staff.

  Furthermore, since both the landing LA control key switch 20 and the car LA control key switch 28 can be operated only by an elevator clerk, misuse of the elevator apparatus in an emergency situation is prevented.

  Furthermore, since the evacuation operation is completely controlled by the elevator clerk, passengers can be trusted and panic can be reduced.

  Further, since the disabled person call indicator 27 is provided in the car 4, the elevator staff can easily grasp the floor where the disabled person is located and can efficiently evacuate the disabled person.

Furthermore, since additional information is displayed on the disabled person call indicator 27, the elevator staff must grasp detailed information about the disabled person, make a more appropriate evacuation plan, and carry out smooth evacuation operation. Can do.
Furthermore, by displaying the disability type as additional information, it is possible to respond more appropriately according to the disability type of the passenger waiting for the elevator clerk at the landing.

  Further, by using the clerk communication system, an appropriate evacuation instruction according to the evacuation plan can be given in real time from the elevator clerk to the passengers at the hall. Thereby, a passenger's reliability can be improved and a panic can be reduced.

  Further, since the evacuation floor button 29 is provided on the car operation panel 9 in addition to the destination floor button 21, the elevator clerk can easily move the car 4 directly to the evacuation floor as necessary, further improving the efficiency of the evacuation operation. Can be improved.

  Furthermore, when the designated evacuation floor is a fire occurrence floor, the evacuation floor can be automatically changed by the elevator controller 6. Even in this case, the elevator clerk can move the car 4 to the evacuation floor without hesitation by pressing the evacuation floor button 29. In this case, it is preferable to report the change of the evacuation floor to the passengers and elevator staff in the car 4 by voice announcement.

  In addition, control of the elevator apparatus of Embodiment 1 is not restricted only to use of emergency evacuation, but can also be used for other uses that require priority of the emergency car 4 such as a hospital elevator.

The disabled person call indicator 27 is not limited to the arranged LEDs, and may be a display device, for example.
Furthermore, the number of designated floors is not particularly limited.
Furthermore, the additional information for the handicapped person call is not limited to the handicapped type, and may be, for example, information on the number of persons with disabilities or information on the degree of the handicapped.
Further, in the above example, the elevator clerk can be grasped by dividing the waiting passengers at the hall into healthy persons and physically handicapped persons. However, for example, it may be configured so that children and elderly persons are distinguished and displayed. .

Further, in the above example, the hall LA control key switch 20 is provided on the hall operation panel 12, but it may be provided at a place different from the hall operation panel 12.
Furthermore, in the above example, the car LA control key switch 28 is provided in the car operation panel 9, but it may be provided in a place different from the car operation panel 9.
