Description

[Technical Field]

[0001] The present invention relates generally to elevator control. [Background technology]

[0002] Generally, when an elevator control device detects a disaster such as a fire, it stops operation to any reserved floors, transports passengers using the elevator to evacuation floors, and then suspends operation of the elevator, which remains suspended thereafter so that the elevator cannot be used. Therefore, even if there is no abnormality in the elevator, it cannot be used for evacuation.

[0003] In this regard, an evacuation elevator operation control device has been disclosed that can determine whether or not evacuation operation is possible in the event of a fire, determine whether to start an evacuation operation mode in which evacuation operation is performed, operate the elevator according to the fire and evacuation situation, and issue evacuation requests to each floor by elevator (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4391226 Summary of the Invention [Problem to be solved by the invention]

[0005] The technology described in Patent Document 1 has a problem in that, in the event of a disaster, it is difficult for people at the platform to determine whether or not they can use the elevator car for evacuation.

[0006] The present invention has been made in consideration of the above points, and aims to propose an elevator or the like that makes it easy to grasp the usage status of the elevator car in the event of a disaster. [Means for solving the problem]

[0007] In order to solve the above problem, the present invention provides an elevator control device that operates a car on each of a plurality of floors, wherein a hall operation unit is provided at a hall on each floor for registering a hall call for calling the car, the hall operation unit is configured to include a notification unit for notifying the use state of the car, and is equipped with a switching unit that switches the operation mode of the car to an evacuation mode, and a notification control unit that controls the notification mode of the notification unit, and the notification control unit is configured to control the operation mode of the notification unit by switching the operation mode to an evacuation mode. When the mode is switched to the evacuation mode, the notification units of the platform operation units on all floors are controlled to a first notification mode indicating that the car is available for use, and when the platform operation unit on any floor is operated and a platform call is registered, the notification unit of the platform operation unit on the floor where the platform call is registered is controlled to a second notification mode indicating that the car is being called, and the notification units of the platform operation units on floors other than the floor where the platform call is registered are controlled to a third notification mode indicating that the car is unavailable.

[0008] According to the above configuration, when the operation mode is switched to the evacuation mode, a notification is made as to whether or not the elevator car can be used, so that, for example, in the event of a disaster, people at the platform can decide whether or not to evacuate using the elevator car. [Effects of the Invention]

[0009] According to the present invention, it is possible to realize an elevator with high convenience. Problems, configurations, and effects other than those described above will become clear from the following description of the embodiment. [Brief explanation of the drawings]

[0011] (I) First embodiment An embodiment of the present invention will be described in detail below, but the present invention is not limited to the embodiment.

[0012] In the event of a disaster, if the elevator is able to operate normally, the elevator control device of this embodiment flashes all hall call buttons (hall buttons) for floors that are permitted to be used, and when any one hall button is operated to register a hall call, it services the registered hall call, assuming that the elevator car is unoccupied. Furthermore, when a hall call is registered, the elevator control device stops flashing hall buttons for other floors. With the above configuration, when a disaster occurs, people at the hall can easily and quickly determine whether they can use the elevator car for evacuation.

[0013] Next, an embodiment of the present invention will be described with reference to the drawings. The following description and drawings are examples for explaining the present invention, and some omissions and simplifications have been made as appropriate for clarity of explanation. The present invention can be implemented in various other forms. Unless otherwise specified, each component may be singular or plural.

[0014] In the following description, the same elements in the drawings are given the same numbers, and the description will be omitted as appropriate. When describing elements of the same type without distinguishing between them, the common part (the part excluding the branch number) of the reference signs including the branch number will be used, and when describing elements of the same type while distinguishing between them, the reference signs including the branch number will be used. For example, when describing a platform operating panel without any particular distinction, it will be written as "platform operating panel 170", and when describing individual platform operating panels while distinguishing between them, it will be written as "platform operating panel 170-1", "platform operating panel 170-2", etc.

[0015] The designations "first," "second," "third," etc. in this specification are used to identify components and do not necessarily limit the number or order. Furthermore, numbers used to identify components are used in different contexts, and numbers used in one context do not necessarily indicate the same configuration in another context. Furthermore, this does not prevent a component identified by a certain number from also serving the function of a component identified by another number.

[0016] In FIG. 1, 100 generally indicates an elevator according to a first embodiment.

[0017] 1 is a diagram showing an example of an elevator (elevator 100) according to this embodiment. The elevator 100 includes a car 110 that moves up and down in a hoistway, a counterweight 130 connected to the car 110 via a main rope 120, a hoist 140 that winds up the main rope 120 to raise and lower the car 110 and the counterweight 130, a control panel 150 that includes a controller 151 that controls the hoist 140, and a tail cord 160 that electrically connects an in-car operation panel 111 installed in the car 110 with the control panel 150 and transmits and receives signals. In this embodiment, the hoist 140 and the control panel 150 are shown to be provided in a machine room located at the top of the hoistway, but the present invention is not limited to this configuration.

[0018] Furthermore, the elevator 100 is provided with hall operating panels 170-1 to 170-n at the elevator halls (landings) on each floor. The hall operating panel 170 is provided with hall buttons for registering hall calls to call the car 110 when moving to an upper floor or a lower floor. The hall operating panel 170-1 on the lowest floor is provided with a hall button for specifying movement to an upper floor, and the hall operating panel 170-n on the top floor is provided with a hall button for specifying movement to a lower floor. The hall operating panels 170 on the other intermediate floors are provided with hall buttons for specifying movement to an upper floor and hall buttons for specifying movement to a lower floor.

[0019] The elevator car 110 has three operating modes: a normal mode, a control mode, and an evacuation mode. The normal mode is an operating mode in which the elevator car 110 provides services to users. In the normal mode, users can go to their desired destination floor by operating the hall operating panel 170 or the in-car operating panel 111. The control mode is an operating mode that is activated when the elevator 100 detects a disaster. In the control mode, the in-car operating panel 111 stops operation to the reserved floor and immediately operates the elevator car 110 directly to the nearest floor or a predetermined evacuation floor (e.g., an entrance floor). Once passengers have disembarked, the doors close and the elevator enters a halt state. The evacuation mode is an operating mode that is activated when there is no abnormality in the elevator 100 during a disaster. In the evacuation mode, the elevator car 110 accepts an operation on the hall operating panel 170, moves the elevator car 110 to the floor where the operated hall operating panel 170 is installed, and then operates the elevator car 110 directly to the evacuation floor.

[0020] In the evacuation mode, to notify that the evacuation mode is in effect, for example, the hall button on the hall operating panel 170 flashes (notification mode 171). When a hall button on the hall operating panel 170 of one of the floors is operated, the hall button is lit, and the hall buttons on the hall operating panels 170 of the other floors are turned off (notification mode 172).

[0021] In the following, an example will be described in which the elevator 100 is installed in a five-story building.

[0022] 2 is a diagram showing an example of the in-car operation panel 111. The in-car operation panel 111 is provided with a button 211 that accepts an operation by a passenger to specify the destination floor of the car 110, an open button 212 that accepts an operation by a passenger to open the door of the car 110, and a close button 213 that accepts an operation by a passenger to close the door of the car 110.

[0023] The buttons 211 are arranged in a vertical line corresponding to the floors of the elevator hall. The buttons 211 may be contact-type or contactless. For example, a user can specify a destination floor by pressing the button 211 or by bringing a fingertip close to the button 211.

[0024] The car operation panel 111 is also provided with an information display unit 220 that displays information such as the current position of the car 110 and the next floor to stop at.

[0025] 3 is a diagram showing an example of the hall operating panel 170. The hall operating panel 170 is provided with a button 311 that accepts an operation by a passenger to call the car 110, and an information display unit 320 that displays information such as the current location of the car 110 and the next stopping floor. The button 311 may be of a contact type or a non-contact type. For example, a user can call the car 110 by pressing the button 311 or by bringing a fingertip close to the button 311.

[0026] FIG. 4 is a diagram showing an example of a functional configuration of the elevator 100 according to this embodiment.

[0027] The car operating panel 111 is configured to include a button 211 and a button response light 411 that emits light in response to a command signal from the control panel 150. The button response light 411 is, for example, a light-emitting member (for example, an LED: Light Emitting Diode) that is provided corresponding to the button 211 and illuminates the back side of the button 211. The hall operating panel 170 is configured to include a button 311 and a button response light 421 that emits light in response to a command signal from the control panel 150. The button response light 421 is, for example, a light-emitting member (for example, an LED) that is provided corresponding to the button 311 and illuminates the back side of the button 311.

[0028] The control panel 150 is configured to include an operation control unit 431 that controls the operation of the elevator car 110, and a hoist drive control unit 432 that controls the motor 441 of the hoist 140 based on a signal from the operation control unit 431. The operation control unit 431 is configured to include an input processing unit 433, a destination floor registration processing unit 434 in the car, and a destination floor registration processing unit 435 at the hall.

[0029] The input processing unit 433 processes signals resulting from the operation of the button 211 on the car operation panel 111, and processes signals resulting from the operation of the button 311 on the hall operation panel 170. The input processing unit 433 converts, for example, an analog detection signal corresponding to the operation content of the user into a digital signal.

[0030] The in-car destination floor registration processing unit 434 performs processing related to the registration of a destination floor for the car 110. For example, the in-car destination floor registration processing unit 434 registers a destination floor (disembarkation floor) based on information processed by the input processing unit 433, and outputs a command signal to the hoist drive control unit 432 to operate the car 110 to the registered destination floor. Also, for example, the in-car destination floor registration processing unit 434 outputs a command signal to the button response light 411 to turn on the button response light 411 of the button 211 corresponding to the registered destination floor. Signals are transmitted and received between the operation control unit 431 and the in-car operation panel 111 via a tail code 160.

[0031] The hall destination floor registration processing unit 435 performs processing related to the registration of hall calls for the car 110. For example, the hall destination floor registration processing unit 435 registers a destination floor (boarding floor) based on information processed by the input processing unit 433, and outputs a command signal to the hoist drive control unit 432 to operate the car 110 to the registered destination floor. Also, for example, the hall destination floor registration processing unit 435 outputs a command signal to the button response light 421 to turn on the button response light 421 of the button 311 corresponding to the registered destination floor. Signals are transmitted and received between the operation control unit 431 and the hall operating panel 170 via wire or wirelessly.

[0032] The control panel 150 is an example of an elevator control device, and is configured to include, for example, a computer, and is provided with a processor, storage devices such as RAM (Random Access Memory) and ROM (Read Only Memory), a communication device, etc., all of which are omitted from the drawing.

[0033] The functions of the control panel 150 (such as the operation control unit 431 and the hoist drive control unit 432) may be realized, for example, by a processor reading a program stored in a ROM into a RAM and executing it (software), or by hardware such as a dedicated circuit, or by a combination of software and hardware. One function of the control panel 150 may be divided into multiple functions, or multiple functions may be combined into one function. For example, the operation control unit 431 may be divided into a switching unit, a notification control unit, a registration unit, a detection unit, and the like. The switching unit switches the operation mode of the car 110 to an evacuation mode. The notification control unit controls the notification mode of the notification unit (such as the button response light 411 and the button response light 421). The registration unit registers the destination floor of the car 110 received by the reception unit (such as the button 211 and the button 311). The detection unit detects passengers in the car 110.

[0034] Furthermore, some of the functions of the control panel 150 may be provided as separate functions or may be included in other functions. Furthermore, some of the functions of the control panel 150 may be realized by other components (such as the car operating panel 111 and the hall operating panel 170) that can communicate with the control panel 150. Furthermore, each of the hardware components of the control panel 150 may be one or more.

[0035] 5 is a diagram showing an example of the operation mode setting process executed by the operation control unit 431. The operation mode setting process is executed at predetermined time intervals.

[0036] In step S501, the operation control unit 431 determines whether or not a disaster has occurred. If the operation control unit 431 determines that a disaster has not been detected, the process proceeds to step S502. If the operation control unit 431 determines that a disaster has been detected, the process proceeds to step S503.

[0037] In step S502, the operation control unit 431 sets the operation mode of the car 110 to the normal mode, and moves the process to step S501.

[0038] In step S503, the operation control unit 431 determines whether or not a switch to the evacuation elevator has been detected. If the operation control unit 431 determines that a switch to the evacuation elevator has been detected, it proceeds to step S504, and if it determines that a switch to the evacuation elevator has not been detected, it proceeds to step S505. Detection of a switch to the evacuation elevator is performed automatically or manually when there is no abnormality in the car 110 (when the car 110 can operate normally).

[0039] For example, when the operation control unit 431 detects a fire, if power is being supplied, the fire doors at the landing are closed, and the sprinklers at the landing are not operating, it determines that the elevator car 110 can operate normally and detects a switch to an evacuation elevator.

[0040] Furthermore, in the event of a disaster, there may be cases where the actual situation inside the building cannot be received correctly or is incorrect, and although the elevator 110 can operate normally, external information may prohibit its use as an evacuation elevator 110. In this regard, for example, by configuring the elevator to switch to an evacuation elevator when an evacuation switch installed in the machine room, the landing of the evacuation floor, the control room, or the like is operated, it becomes possible to use the elevator 110 for evacuation purposes based on on-site judgment without being influenced by external information.

[0041] In step S504, the operation control unit 431 sets the operation mode of the car 110 to the evacuation mode, and moves the process to step S501. In the evacuation mode, the evacuation operation process described below is executed.

[0042] In step S505, the operation control unit 431 sets the operation mode of the car 110 to the control mode, and proceeds to step S501. In addition, when the occurrence of a disaster is detected, the control mode is set first, so there are no passengers in the car 110 when the evacuation mode is set.

[0043] 6 is a diagram showing an example of evacuation operation processing executed by the operation control unit 431. The evacuation operation processing is executed at predetermined time intervals.

[0044] In step S601, the operation control unit 431 outputs a command signal to the button response lights 421 of the buttons 311 of all floors to make them blink (flicker) in a predetermined manner.

[0045] In step S602, the operation control unit 431 determines whether or not any floor button 311 has been operated. If the operation control unit 431 determines that any floor button 311 has been operated, it proceeds to step S603, and if it determines that none of the floor buttons 311 have been operated, it proceeds to step S601.

[0046] In step S603, the operation control unit 431 registers the hall call of the operated button 311. At this time, the operation control unit 431 processes whether the up or down button 311 is operated as the button 311 for the evacuation floor direction. According to this processing, even if the user hastily operates the button 311 for the wrong direction, the user can be properly guided to the evacuation floor.

[0047] In step S604, the operation control unit 431 turns off the button response lights 421 of the buttons 311 of the other floors, and prohibits the registration of hall calls by operating the buttons 311 of the other floors.

[0048] In step S605, the operation control unit 431 determines whether the elevator 110 has landed at the floor where the hall call is registered and moved to the evacuation floor, and whether the passengers have disembarked (whether the service is completed). If the operation control unit 431 determines that the service is completed, it moves the process to step S601, and if it determines that the service is not completed, it moves the process to step S604. When the elevator 110 has landed at the floor where the hall call is registered, the operation control unit 431 turns off the button response light 421 of the button 311 of the operated floor.

[0049] 7 is a diagram showing an example of a notification mode in the hall operating panel 170. In this embodiment, examples are shown of a notification mode in the hall operating panel 170 on the fourth floor where a hall call is registered, and a notification mode in the hall operating panel 170 on the third floor, which is another floor.

[0050] Before switching to the evacuation mode, the hall buttons on all floors are in a notification mode (for example, off 711) indicating that the elevator car 110 is unavailable.

[0051] When the mode is switched to the evacuation mode, the hall buttons on all floors are in a notification mode (for example, flashing 721) that indicates that the elevator car 110 can be used for evacuation.

[0052] When the platform button is flashing 721, for example, if a user on the fourth floor operates the platform button, the platform button for the fourth floor will be in an alert state (for example, lit 731) indicating that a platform call has been registered, and the platform buttons for other floors such as the third floor will be, for example, unlit 711.

[0053] After that, from when the elevator 110 lands on the fourth floor until the passenger gets off (the service is completed), the hall buttons for all floors are turned off, for example, 711. Then, when the service is completed, the hall buttons for all floors are turned on, for example, 721.

[0054] Furthermore, when the evacuation mode is cancelled, the landing buttons on all floors are turned off, for example 711.

[0055] According to this embodiment, a person at an elevator hall can know whether or not the elevator can be used as an evacuation elevator in the event of a disaster, and can use the elevator at his or her own discretion.

[0056] (II) Second embodiment The second embodiment differs from the first embodiment mainly in that the disembarking floor is automatically registered in the evacuation mode. In this embodiment, the same components as those in the first embodiment are designated by the same reference numerals and will not be described again.

[0057] FIG. 8 is a diagram showing an example of a functional configuration of an elevator 800 according to this embodiment.

[0058] The elevator 800 includes a control panel 150, an in-car operating panel 111, a hall operating panel 170, a motor 441, and a passenger detection sensor 801.

[0059] The passenger detection sensor 801 is a sensor capable of detecting passengers, and is a load sensor provided in the car 110, a camera provided at the landing, etc. The sensor information acquired by the passenger detection sensor 801 is processed by the input processing unit 433.

[0060] 9 is a diagram showing an example of the evacuation operation process according to this embodiment. The evacuation operation process is executed at predetermined time intervals.

[0061] In step S901, the operation control unit 431 determines whether or not there is a passenger in the car 110. If the operation control unit 431 determines that there is a passenger in the car 110, it performs the process of step S901 again, and if it determines that there is no passenger in the car 110, it moves the process to step S601. Note that, since sharing a car in the evacuation mode poses a risk to the other party, the car 110 becomes available when there is no passenger in the car 110.

[0062] In step S902, the operation control unit 431 determines whether or not the car 110 has landed on the floor where the button 311 of the hall operating panel 170 was operated. If the operation control unit 431 determines that the car 110 has landed, it shifts the processing to step S903, and if it determines that the car 110 has not landed, it shifts the processing to step S604.

[0063] In step S903, the operation control unit 431 turns off the button response light 421 of the operated button 311, and prohibits the registration of a hall call by operating this button 311.

[0064] In step S904, the operation control unit 431 determines whether or not a user action has been taken. If the operation control unit 431 determines that a user action has been taken, it proceeds to step S906, and if it determines that a user action has not been taken, it proceeds to step S905. A user action may be a user getting on the elevator car 110, a user operating any of the buttons 211 on the elevator control panel 111, or the like.

[0065] In step S905, the operation control unit 431 determines whether a certain time has passed since the elevator car 110 landed on the floor. If the operation control unit 431 determines that the certain time has passed, it shifts the process to step S901, and if it determines that the certain time has not passed, it shifts the process to step S904.

[0066] In step S906, the operation control unit 431 registers the evacuation floor (descent floor) and moves the process to step S901. At this time, the operation control unit 431 outputs a command signal to the button response lights 411 to turn on the button response lights 411 of the button 211 corresponding to the evacuation floor and to turn off the button response lights 411 of the buttons 211 of floors other than the evacuation floor. In addition, the operation control unit 431 prohibits the registration of a destination floor (descent floor) by operating the button 211.

[0067] Note that the evacuation operation processing is not limited to the above-described configuration. For example, the operation control unit 431 may register an evacuation floor as a disembarking floor when registering a hall call from a hall button. In this case, the operation control unit 431 outputs a command signal to the button response lights 411 to turn on the button response lights 411 of the buttons 211 corresponding to the evacuation floor and to turn off the button response lights 411 of the buttons 211 of floors other than the evacuation floor. In addition, the operation control unit 431 prohibits the registration of a destination floor (disembarking floor) by operating the buttons 211.

[0068] According to this embodiment, the disembarking floor is automatically registered, so even if a passenger is in a panic, the passenger can be taken to an evacuation floor.

[0069] (III) Supplementary Note The above-described embodiment includes, for example, the following contents.

[0070] In the above embodiment, the present invention is described as being applied to an elevator, but the present invention is not limited to this and can be widely applied to various other systems, devices, methods, and programs.

[0071] Furthermore, in the above embodiment, the notification mode has been described as the case where the button response light 421 of the hall operating panel 170 flashes, lights up, or goes out, but the present invention is not limited to this. For example, in addition to or instead of the button response light 421 of the hall operating panel 170, the information display unit 320 of the hall operating panel 170 may flash, light up, or go out.

[0072] Furthermore, in the above-described embodiment, the hall operating panel 170 is described as being equipped with the button response light 421, but the present invention is not limited to this. For example, the hall operating panel 170 may be equipped with a speaker. In this case, the speaker may be controlled in addition to or instead of the button response light 421. For example, when the operation mode is switched to the evacuation mode, the operation control unit 431 controls the speakers of the hall operating panels 170 of all floors to output a first sound indicating that the car 110 is available (for example, "You can use the elevator for evacuation."). Furthermore, when the hall operating panel 170 of any floor is operated to register a hall call, the operation control unit 431 controls the speaker of the hall operating panel 170 of the floor where the hall call is registered to output a second sound indicating that the car 110 is being called (for example, "The elevator will arrive shortly."). Then, the system controls the speaker of the hall operating panel 170 at floors other than the floor where the hall call is registered to output a third voice (for example, "The elevator is currently unavailable") indicating that the elevator 110 is unavailable.

[0073] In the above-described embodiment, some or all of the programs may be installed from a program source into a device such as a computer that implements control panel 150. The program source may be, for example, a program distribution server connected via a network or a computer-readable recording medium (e.g., a non-transitory recording medium). In the above description, two or more programs may be implemented as one program, or one program may be implemented as two or more programs.

[0074] In addition, in the above description, information such as programs, tables, files, etc. that realize each function can be stored in a storage device such as a memory, a hard disk, or an SSD (Solid State Drive), or in a recording medium such as an IC card, an SD card, or a DVD.

[0075] The above-described embodiment has the following characteristic configurations, for example.

[0076] (1) An elevator control device (e.g., a control panel 150, a control controller 151) that operates a car (e.g., a car 110) on each of a plurality of floors, wherein a hall operation unit (e.g., a hall operation panel 170) for registering a hall call to call the car is provided at a hall on each floor, and the hall operation unit is configured to include a notification unit (e.g., a response light 421, an information display unit 320, a speaker) for notifying the use status of the car, and is equipped with a switching unit (e.g., the control panel 150, the control controller 151, an operation control unit 431, a switching unit) that switches the operation mode of the car to an evacuation mode, and a notification control unit (e.g., the control panel 150, the control controller 151, the operation control unit 431, a notification control unit) that controls the notification mode of the notification unit. When the operation mode is switched to the evacuation mode by the switching unit, the notification control unit controls the notification units of the platform operation units of all floors to a first notification mode (for example, flashing 721, flashing of the information display unit 320, and a first voice) indicating that the car is available, and when the platform operation unit of any floor is operated and a platform call is registered, the notification control unit controls the notification unit of the platform operation unit of the floor where the platform call is registered to a second notification mode (for example, lighting 731, lighting of the information display unit 320, and a second voice) indicating that the car is being called, and controls the notification units of the platform operation units of floors other than the floor where the platform call is registered to a third notification mode (for example, lighting off 711, turning off the information display unit 320, and a third voice) indicating that the car is unavailable.

[0077] According to the above configuration, when the operation mode is switched to the evacuation mode, a notification is made as to whether or not the elevator car can be used, so that, for example, in the event of a disaster, people at the platform can decide whether or not to evacuate using the elevator car.

[0078] (2) The car is provided with a registration unit (e.g., a control panel 150, a control controller 151, an operation control unit 431, a registration unit, a destination floor registration processing unit 434 in the car) that registers the destination floor of the car, and when the operation mode of the car is in evacuation mode and a hall operation unit of any floor is operated to register a hall call, the registration unit registers a pre-set evacuation floor as the disembarking floor of the car (e.g., see Figure 9).

[0079] According to the above configuration, when a hall call is registered, an evacuation floor is automatically registered, so that even if a user does not know the evacuation floor, for example, the user can be evacuated quickly.

[0080] (3) The car is equipped with a registration unit (e.g., control panel 150, control controller 151, operation control unit 431, registration unit, destination floor registration processing unit 434 inside the car) that registers the destination floor of the car, and the car is configured to include an in-car operation unit (e.g., in-car operation panel 111) that has a reception unit (e.g., button 211) for receiving the disembarking floors provided for each floor, and when the operation mode of the car is evacuation mode and any of the reception units of the in-car operation unit is operated, the registration unit registers a pre-set evacuation floor as the disembarking floor for the car (e.g., see Figure 9).

[0081] According to the above configuration, the evacuation floor is registered regardless of which reception unit is operated, so that even if, for example, a reception unit on a floor other than the evacuation floor is operated in a panic, passengers can be taken to the evacuation floor.

[0082] (4) The car is provided with a registration unit (e.g., control panel 150, control controller 151, operation control unit 431, registration unit, destination floor registration processing unit 434 in the car) that registers the destination floor of the car, and a detection unit (e.g., control panel 150, control controller 151, operation control unit 431, detection unit) that detects passengers in the car, and when the operation mode of the car is evacuation mode, a hall operation unit of any floor is operated to register a hall call, the car lands on the floor where the hall call is registered, and a passenger is detected by the detection unit, the registration unit registers a pre-set evacuation floor as the disembarking floor of the car (e.g., see Figures 8 and 9).

[0083] According to the above configuration, an evacuation floor is registered when a user gets into a car, so that even if the user is in a panic and unable to make normal decisions, the passenger can be taken to the evacuation floor.

[0084] (5) The notification unit of the platform operation unit provided at the platform of each floor is a response light (for example, button response light 421), and when the operation mode is switched to the evacuation mode by the switching unit, the notification control unit controls the response lights of the platform operation units of all floors to flash, and when the platform operation unit of any floor is operated and a platform call is registered, controls the response light of the platform operation unit of the floor where the platform call is registered to light up, and controls the response lights of the platform operation units of floors other than the floor where the platform call is registered to light up (for example, see FIG. 7).

[0085] In the above configuration, the response light flashes when the car is available, lights up when the car is being called, and turns off when the car is unavailable, so that, for example, a person at the boarding area can easily know whether the car is available or not.

[0086] (6) The notification control unit controls the response lights of the hall operation units of the floor to be turned off when the elevator lands on the floor where the hall call is registered, and controls the response lights of the hall operation units of all floors to be flashed when the service for the hall call is completed (see, for example, Figures 6, 7 and 9).

[0087] According to the above configuration, the lights remain off until service for the hall call is completed, so that, for example, passengers can be prevented from sharing rides from intermediate floors between the boarding floor and the disembarking floor.

[0088] Furthermore, the above-described configurations may be modified, rearranged, combined, or omitted as appropriate within the scope of the present invention.

[0089] It should be understood that items included in a list in the format "at least one of A, B, and C" can mean (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C).
