DESCRIPTION OF EMBODIMENTS

With reference to the accompanying drawings, embodiments of the present invention will be described. In the drawings, the same or corresponding components are denoted by the same reference numerals. Overlapping descriptions of the components will be appropriately simplified or omitted.

Embodiment 1

FIG. 1 is a configuration diagram of an elevator system according to Embodiment 1 of the present invention.

FIG. 1 schematically shows an elevator system. In FIG. 1, a plurality of emergency detectors 1 are each provided on floors of a building. For example, the plurality of emergency detectors 1 are fire detectors (fire alarms). In the building, an evacuation floor in case of an emergency is set. For example, the evacuation floor is set to a first floor with an entrance connecting the inside and outside of the building.

A hoistway 2 of an elevator extends through the floors of the building. A plurality of halls 3 of the elevator are provided on the floors of the building so as to face the hoistway 2. A plurality of cars 4 of the elevator are provided in the hoistway 2. The plurality of cars 4 are provided so as not to overlap on a horizontal projection plane. The plurality of cars 4 are provided to be able to move up and down in the hoistway 2 by power of a traction machine (not shown).

On the plurality of halls 3, a plurality of hall doors 5 are provided correspondingly to the plurality of cars 4.

A plurality of car doors 6 are provided in the plurality of cars 4.

On each of the plurality of halls 3, one of the plurality of hall destination floor input devices 7 is provided on a wall surface between a leftmost hall door 5 and a middle hall door 5. The other of the plurality of hall destination floor input devices 7 is provided on a wall surface between a rightmost hall door 5 and the middle hall door 5. The plurality of hall destination floor input devices 7 each include an information input unit 7a, a signal transmission unit 7b, a signal receiving unit 7c, an announcing unit 7d, and a control unit 7e.

A plurality of ear operating panels 8 are provided in the plurality of cars 4. For example, the plurality of car operating panels 8 each include a door closing button 8a and a door opening button 8b.

For example, a control system 9 is provided in the building. For example, the control system 9 is provided above the hoistway 2. For example, the control system 9 includes a detection unit 9a, a signal receiving unit 9b, a signal transmission unit 9c, and a control unit 9d.

For example, a monitoring device 10 is provided in the building. For example, the monitoring device 10 is provided in a monitoring room in the building.

If an emergency does not occur on any floors in the building, the emergency detectors 1 on any floors do not detect an emergency. In this case, the monitoring device 10 does not detect an emergency. In this case, the monitoring device 10 does not transmit emergency information.

If the monitoring device 10 does not transmit emergency information, the detection unit 9a of the control system 9 does not receive emergency information from the monitoring device 10. In this case, an operation mode of the control system 9 is a normal mode. The normal mode here refers to a mode other than an emergency mode based on emergency information of the building.

In this case, if the information input unit 7a of any hall destination floor input device 7 receives input of information on a destination floor from a user of the elevator, the control unit 7e causes the signal transmission unit 7b to transmit a signal for a destination call corresponding to the destination floor. Specifically, the control unit 7e causes the signal transmission unit 7b to transmit a signal indicating a floor provided with the hall destination floor input device 7 and the destination floor.

The signal receiving unit 9b of the control system 9 receives the signal indicating the floor provided with the hall destination floor input device 7 and the destination floor from the hall destination floor input device 7. The control unit 9d determines a car 4 to be assigned to a hall call corresponding to the floor provided with the hall destination floor input device 7 and a car call corresponding to the destination floor. The control unit 9d causes the signal transmission unit 9c to transmit a signal indicating the car 4.

The signal receiving unit 7c of the hall destination floor input device 7 receives the signal indicating the car 4 from the control system 9. The control unit 7e causes the announcing unit 7d to announce information indicating the car 4.

The control unit 9d of the control system 9 causes the car 4 to respond to the hall call. As a result, the car 4 reaches the floor provided with the hall destination floor input device 7 to pick up the user. Then, the control unit 9d causes the car 4 to respond to the car call. As a result, the car 4 reaches the destination floor to discharge the user.

For example, if an emergency occurs on any floor, the emergency detector 1 on the floor detects the emergency. The monitoring device 10 detects the emergency based on a detection result of the emergency detector 1. In this case, the monitoring device 10 transmits emergency information to the control system 9.

Here, the case where the emergency detector 1 transmits the emergency information to the control system 9 via the monitoring device 10 has been described, but an emergency control operation may be performed using a manual switch. During the emergency control operation, the emergency information is transmitted directly from the emergency detector 1 to the control system 9.

The detection unit 9a of the control system 9 receives the emergency information from the monitoring device 10. In this case, the control system 9 switches the operation mode to the emergency mode.

In this case, the control unit 9d of the control system 9 causes the plurality of cars 4 to travel to the evacuation floor. Then, the control unit 9d opens the car door 6 of the car 4 and the hall door 5 corresponding to the car 4 for a preset time so as to urge a user in the car 4 having reached the evacuation floor to evacuate. Then, the control unit 9d causes the car 4 to stand by with the door closed. Specifically, the control unit 9d causes the car 4 to stand by on the evacuation floor with the car door 6 and the hall door 5 closed.

When the operation mode of the control system 9 is switched to the emergency mode, the control unit 9d causes the signal transmission unit 9c to transmit an emergency signal to the plurality of hall destination floor input devices 7 on the evacuation floor.

The signal receiving units 7c of the plurality of hall destination floor input devices 7 on the evacuation floor receive the emergency signal. The control unit 7e switches the operation mode of the hall destination floor input device 7 to the emergency mode. The control unit 7e causes the announcing unit 7d to announce information indicating that the elevator cannot be used. For example, the control unit 7e causes the announcing unit 7d to display textual information of “Out of Service”.

In this state, when the information input unit 7a starts receiving input of information, the control unit 7e causes the signal transmission unit 7b to transmit a signal to open the door of the elevator on the hall 3. For example, when a firefighter having rushed to the evacuation floor starts input of information using the information input unit 7a, the control unit 7e causes the signal transmission unit 7b to transmit a signal to open the door of the elevator on the hall 3.

The signal receiving unit 9b of the control system 9 receives the signal to open the door of the elevator on the hall 3 from the hall destination floor input device 7. The control unit 9d opens the car door 6 of the car 4 and the hall door 5 corresponding to the car door 6 for a preset time, the car 4 standing by on the evacuation floor with the car door 6 and the hall door 5 closed. For example, in FIG. 1, the control unit 9d opens the car door 6 of the middle car 4 and the hall door 5 corresponding to the car door 6 for a preset time, the middle car 4 standing by on the evacuation floor with the car door 6 and the hall door 5 closed. If the plurality of cars 4 are standing by on the evacuation floor with their doors closed, the car doors 6 of the cars 4 and the hall doors 5 corresponding to the car doors 6 are opened for a preset time.

In this case, the firefighter checks that the user is not trapped in the car 4. Then, the control unit 9d closes the car door 6 and the hall door 5 and causes the car 4 to stand by on the evacuation floor.

On the other hand, the control unit 9d does not open the car door 6 of the car 4 having not reached the evacuation floor, and the hall door 5 corresponding to the car door 6.

If the door opening button 8b on the car operating panel 8 is pressed in the car 4 standing by on the evacuation floor with the ear door 6 and the hall door 5 corresponding to the car door 6 closed, the control unit 9d opens the car door 6 and the hall door 5 corresponding to the car door 6. Thus, even if the user is stranded in the car 4 on the evacuation floor, the user can escape from the car 4 by himself/herself.

Next, with reference to FIG. 2, an example of the hall destination floor input device 7 on the evacuation floor will. be described.

The control board 11h serves as the control unit 7e in FIG. 1. The control board 11h controls the overall operation of the hall destination floor input device 7. The control board 11h performs different controls according to the operation mode of the hall destination floor input device 7.

For example, if the operation mode of the hall destination floor input device 7 is the normal mode, the control board 11h determines whether or not any button is pressed again before a preset time elapses after any one button of the numeric keypad button 11b is pressed. If the preset time simply elapses without any button being pressed again after any one button of the numeric keypad button 11b is pressed, the control board 11h transmits, via the interface 11a, a signal indicating a destination floor corresponding to a one-digit number, which corresponds to the pressed button. If any button is pressed before the preset time elapses after any one button of the numeric keypad button 11b is pressed, the control board 11h transmits, via the interface 11a, a signal indicating destination floors corresponding to a two-digit number, which corresponds to the two pressed buttons. For example, when the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, a signal to open the door of the elevator on the hall 3 immediately after any one button of the numeric keypad button 11b is pressed, without waiting for the elapse of the preset time.

For example, if the operation mode of the hall destination floor input device 7 is the normal mode, the control board 11h transmits, via the interface 11a, a signal indicating a destination floor for a physically impaired person when the numeric keypad button 11b is pressed after the button for physically impaired person 11c is pressed. For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, a signal to open the door of the elevator on the hall 3 immediately after the button for physically impaired person 11c is pressed.

For example, if the operation mode of the hall destination floor input device 7 is the normal mode, the control board 11h transmits, via the interface 11a, a signal indicating a destination floor corresponding to identification information when the reader 11d reads the identification information from the tag. For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, a signal to open the door of the elevator on the hall 3 immediately after the reader 11d reads identification information of the firefighter from the tag.

For example, if the operation mode of the hall destination floor input device 7 is the normal mode, the control board 11h transmits, via the interface 11a, a signal indicating a destination floor when the microphone 11e receives input of voice information on the destination floor. For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, a signal to fully open the door of the elevator on the hall 3 immediately after the microphone 11e starts receiving the input of voice information.

If the control system 9 has received the signal to open the door of the elevator in Step S21, the control system 9 performs an operation in Step S22.

In Step S22, the control system 9 opens the car door 6 of the car 4 and the hall door 5 for a preset time, the car 4 standing by on the evacuation floor with the car door 6 and the hall door 5 closed. Then, the control system 9 performs an operation in Step S23. In Step S23, the control system 9 closes the car door 6 and the hall door 5. Then, the control system 9 again performs the operation in Step S11.

According to Embodiment 1 described above, if the operation mode of the hall destination floor input device 7 is the emergency mode, the hall destination floor input device 7 provided on the evacuation floor transmits the signal to open the door of the elevator on the hall 3 on the evacuation floor when the hall destination floor input device 7 starts receiving the input of information. This allows an easy check of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h immediately transmits, via the interface 11a, the signal to open the door of the elevator on the hall 3 before the preset time elapses after any one button of the numeric keypad button 11b is pressed. This allows an immediate cheek of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, the signal to open the door of the elevator on the hall 3 immediately after the button for physically impaired person 11c is pressed. This allows an immediate check of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

For example, if the operation mode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, the signal to open the door of the elevator on the hall 3 immediately after the reader 11d reads the identification information of the firefighter from the tag. This allows an immediate check of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

For example, if the operation ode of the hall destination floor input device 7 is the emergency mode, the control board 11h transmits, via the interface 11a, the signal to fully open the door of the elevator on the hall 3 immediately after the microphone 11e starts receiving the input of voice information. This allows an immediate check of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

Specifically, if the hall destination floor input device 7 starts receiving the input of information to transmit the signal to fully open the door of the elevator, the control board 11h fully opens the car door 6 of the car 4 standing by on the evacuation floor with its door closed, and the hall door 5 corresponding to the car door 6. This allows a more reliable check of whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed in case of an emergency.

Also, if the hall destination floor input device 7 receives the input of information to transmit information to open the door of the elevator on the hall 3, the car door 6 of the car 4 standing by on the evacuation floor with its door closed, and the hall door 5 corresponding to the car door 6 may be operated to be opened. If the hall destination floor input device 7 stops receiving the input of information to stop transmitting the signal to open the door of the elevator on the hall 3, the car door 6 of the car 4 standing by on the evacuation floor with its door closed, and the hall door 5 corresponding to the car door 6 may be operated to be closed. In this case, the car 4 can be caused to stand by with its door closed immediately after whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed is checked in case of an emergency.

The case with the plurality of cars 4 moving through the plurality of hoistways 2 has been described so far. However, the control system 9 according to Embodiment 1 may be applied to an elevator including only one hoistway 2 and one car 4. In this case, the car control device 12b may serve as the detection unit 9a, the signal receiving unit 9b, the signal transmission unit 9c, and the control unit 9d. Also in this case, whether or not the user is trapped in the car 4 standing by on the evacuation floor with its door closed can be easily checked in case of an emergency.

Next, with reference to FIG. 6, an example of the control board 11h will be described.

FIG. 6 is a configuration diagram of hardware of the control board of the hall destination floor input device in the elevator system according to Embodiment 1 of the present invention.

Functions of the control board 11h can be achieved by a processing circuitry. For example, the processing circuitry includes at least one processor 13a and at least one memory 13b. For example, the processing circuitry includes at least one dedicated hardware 14.

When the processing circuitry includes the at least one processor 13a and the at least one memory 13b, the functions of the control board 11h are achieved by software, firmware, or a combination of the software and the firmware. At least one of the software and the firmware is described as a program. At least one of the software and the firmware is stored in the at least one memory 13b. The at least one processor 13a reads and executes the program stored in the at least one memory 13b to achieve the functions of the control board 11h. The at least one processor 13a is also referred to as a central processing unit (CPU), a central processing device, a processing device, a computing device, a microprocessor, a microcomputer, or a DSP. For example, the at least one memory 13b is a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

When the processing circuitry includes the at least one dedicated hardware 14, the processing circuitry is achieved by, for example, a single circuit, a complex circuit, a programmed processor, a parallel-programmed processor, an ASIC, a FPGA, or combinations thereof. For example, the functions of the control board 11h are each achieved by the processing circuitry. For example, the functions of the control board 11h are collectively achieved by the processing circuitry.

One part of the functions of the control board 11h may be achieved by the dedicated hardware 14, while the other part may be achieved by the software or the firmware.
