[0004] [Patent Document 1] JP 2014-47059 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the conventional technology, the security button must be installed so as to surround the car, but installing such a security button is not practical and is expensive. The present invention aims to provide an elevator control device, an elevator control method, and an elevator control system that can turn off the destination floor indicator light in a simpler manner without the need to attach an anti-theft button to the elevator car. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention is an elevator control device that controls the turning on and off of an indicator light that displays the destination floor of a user in a car, and includes an information acquisition unit that acquires information on the destination floor to which a security signal is added, an indicator light control unit that controls the turning off of the destination floor indicator light when the security signal is acquired, and a car control unit that controls the operation of the car. In this case, it is not necessary to attach a security button to the car, and an elevator control device that can turn off the destination floor indicator light in a simpler manner can be provided.

[0007] Here, a notification unit may be further provided that notifies the user whether or not the car will stop at the destination floor when the destination floor indicator light is turned off. In this case, the user can know whether or not the car will stop at the destination floor. The notification unit can also notify the user by sound, making it possible to notify the user in a simpler manner. Furthermore, the notification unit can notify the user by displaying the user ID on a display device installed in the elevator. In this case, although the meaning is unclear to fellow passengers, the user can know whether the elevator will stop at the destination floor by his / her user ID. Furthermore, the notification unit can notify the destination floor by turning on an indicator light for the destination floor for a predetermined period of time. In this case, the indicator light is turned on, so that the user can know whether the car will stop at the destination floor. The notification unit can also obtain the user ID via a card reader installed in the elevator, identify the user, and notify the destination floor. In this case, it can be confirmed that the user is in the elevator. Furthermore, the user ID can be acquired in advance via a card reader installed at the elevator landing, and the notification unit can verify the user by checking the user ID acquired via the card reader installed in the elevator car. In this case, it is possible to verify the identity of the user who made the call. Furthermore, a user can register an elevator call using a card reader installed at the elevator hall, making it easier to make an elevator call. The information acquisition unit can acquire the destination floor of the user together with the security signal when registering the elevator call. In this case, the user does not need to perform a special operation such as pressing the security button to send the security signal. In addition, when there is a fellow passenger in the car other than the user, the car control unit can control the car so that the fellow passenger does not know the destination floor of the user. In this case, the inconvenience of the fellow passenger knowing the floor where the user lives is eliminated. The elevator control unit can also control the elevator to stop at a floor other than the destination floor of the user and allow the user to get off. In this case, a simple method can be used to control the elevator so that the destination floor of the user is not known to fellow passengers. Furthermore, the elevator control unit can control the elevator to turn off the floor display that displays the current floor, so that passengers will not know at which floor the elevator has stopped. Furthermore, the elevator control unit can be configured not to perform control when a fellow passenger gets off before the user. In this case, when it is known that the fellow passenger will not know the destination floor, the elevator can be operated under normal control.

[0008] The present invention also provides an elevator control method for controlling the turning on and off of an indicator light that indicates the destination floor of a user in a car, in which a processor executes a program recorded in a memory to obtain information on the destination floor to which a security signal is added, and when the security signal is obtained, controls to turn off the destination floor indicator light and controls the operation of the car. In this case, it is not necessary to attach a security button to the car, and an elevator control method can be provided that can turn off the destination floor indicator light in a simpler manner.

[0009] Furthermore, the present invention provides an elevator control system having a car and an elevator control device that controls the operation of the car, the elevator control device including an information acquisition unit that acquires information on a destination floor to which a security signal is added, an indicator light control unit that controls turning off an indicator light that displays the destination floor of the user in the car when the security signal is acquired, and a car control unit that controls the operation of the car. In this case, it is not necessary to attach a security button to the car, and an elevator control system that can turn off the indicator light of the destination floor in a simpler manner can be provided. Effect of the Invention

[0010] According to the present invention, it is possible to provide an elevator control device, an elevator control method, and an elevator control system that can turn off the destination floor indicator light in a simpler manner without the need to attach an anti-theft button to the elevator car.

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0013] <Overall explanation of elevator control system 1> FIG. 1 is a block diagram showing a functional configuration of an elevator control system 1 to which the present embodiment is applied. The elevator control system 1 includes an elevator control device (control panel) 100 that controls the entire elevator control system 1, a car 200, and a hall terminal 300 that is provided at the elevator hall and that registers destination floors.

[0014] The control device 100 includes an operation control unit 110 and a hoist drive control unit 120. The driving control unit 110 controls the driving of the elevator 200 and controls calls for users. In this embodiment, a "user" is a person who instructs security driving when he does not want fellow passengers to know the destination floor. A "fellow passenger" is a person who rides in the elevator 200 with the user. "Security driving", which will be described in detail later, is a driving method that is performed when a security signal is received from a user, and is a driving method in which the indicator light of the user's destination floor is turned off inside the elevator 200. A "security signal" is a signal that is issued to the driving control unit 110 when a user performs security driving. The operation control unit 110 includes an input / output processing unit 111, a destination floor registration processing unit 112 in the car, a destination floor registration processing unit 113 at the landing, an indicator light control unit 114, a car control unit 115, and a notification unit 116.

[0015] The input / output processing unit 111 is an example of an information acquisition unit, and exchanges information with the car 200 and the platform terminal 300. Specifically, it acquires destination floor information sent from the car 200 and the platform terminal 300. That is, when a user or a fellow passenger presses a destination floor button in the car 200, the destination floor information is sent from the car 200. Also, when a user or a fellow passenger makes a call from the card reader 320 of the platform terminal 300 at the platform, new call information is sent from the registration device 30. Also, the input / output processing unit 111 acquires destination floor information to which a security signal has been added.

[0016] The destination floor registration processing unit 112 in the car registers the destination floor when a user or a fellow passenger presses a button 211 in the car 200. In addition, the destination floor information can be received via the card reader 220. The destination floor registration processing unit 113 at the platform registers the destination floor when a user or a fellow passenger receives destination floor information via the card reader 320 at the platform terminal 300 at the platform.

[0017] The indicator light control unit 114 controls the turning on and off of an indicator light that indicates the destination floor of the user and passengers inside the car 200. When a security signal is acquired, the indicator light control unit 114 controls to turn off the indicator light of the destination floor. This makes it impossible for the passengers who board the car 200 to know the destination floor of the user. When a security signal is not issued, the indicator light control unit 114 performs normal control to turn on the indicator light of the destination floor. The car control unit 115 controls the operation of the car 200. Specifically, when a call is made by a user or a fellow passenger, the car 200 is moved to the floor where the call is made. In addition, when a user or a fellow passenger registers a destination floor in the car 200 or the platform terminal 300, the car 200 is moved to the destination floor.

[0018] When the indicator light of the destination floor is turned off, the notification unit 116 notifies the user whether the car 200 will stop at the destination floor. In other words, when the indicator light of the destination floor is turned on, it is clear to the user whether the car will stop at the destination floor. On the other hand, when the indicator light of the destination floor is turned off, it is unclear to the user whether the car 200 will stop at the destination floor. For example, when there are multiple cars 200 and the user gets on the car 200 that he or she should be getting on, the car will stop at the registered destination floor, but when the user gets on another car 200 by mistake, the car may not stop at the registered destination floor. In this case, the notification unit 116 notifies the user whether the car will stop at the destination floor by a predetermined method. This method will be described later.

[0019] The hoist drive control unit 120 controls the drive of the motor M in accordance with instructions from the operation control unit 110, and controls the raising and lowering and stopping of the car 200. In this way, the car 200 is moved to a boarding area (floor) where a call from a user or passenger has been received. Then, when the user or passenger gets on the car 200, the car 200 is moved to the destination floor.

[0020] The car 200 includes an operation panel 210 and a card reader 220. The operation panel 210 includes a button 211. The button 211 is, for example, a button for a destination floor. The button 211 is, for example, a door open / close button. When a user operates the button 211, the information is sent to the input / output processing unit 111, and a button response is made. The button response is a process of turning on an indicator light of the destination floor button when the destination floor button is pressed. This allows the user to know that the destination floor has been registered. The button response is a process of turning on an indicator light of the door open / close button when the door open / close button is pressed, and actually opening and closing the door.

[0021] The card reader 220 includes a reading device 221 that acquires predetermined information from a mobile terminal device such as an ID card or a smartphone owned by a user. The reading device 221 performs wireless communication with an ID card or a smartphone, for example, using NFC (Near field communication). A user can transmit predetermined information to the card reader 220 by holding an ID card or the like over the reading device 221. Note that the present invention is not limited to this, and the reading device 221 may be a device that performs wireless communication using Wi-Fi (Wireless Fidelity, registered trademark), Bluetooth (registered trademark), or the like. Furthermore, the reading device 221 may be a device that reads magnetic information recorded on an ID card, and the predetermined information is, for example, the destination floor of the user. The predetermined information is then sent to the operation control unit 110 via the card reader 220, and the card reader 220 displays the information. The information display is, for example, a message notifying the user that the destination floor has been registered normally. Or, the information display is, for example, an error message notifying the user that the destination floor has not been registered normally. Also, as will be described in detail later, when a user wants to know whether the train will stop at a destination floor, the user can hold an ID card or the like over the reading device 221 to receive a notification of the destination floor.

[0022] The platform terminal 300 is equipped with a card reader 320. Card reader 320 is used by elevator users at the landing when they register a new call. Like card reader 220, card reader 320 includes reading device 321 that performs wireless communication using NFC or the like. Users can send predetermined information, including the destination floor, to card reader 320 by holding an ID card or the like over reading device 321. The predetermined information is then sent to operation control unit 110 via card reader 320, and card reader 320 displays the same information as card reader 220. In this case, the user registers an elevator call using a card reader 320 installed at the elevator hall. Then, when registering the elevator call, the input / output processing unit 111 acquires the destination floor of the user together with the security signal.

[0023] FIG. 2 is a diagram illustrating the communication format of predetermined information sent from the card readers 220 and 320. As shown in FIG. This information includes the header, boarding floor, exiting floor, attributes, security signal, user ID, and check code. The boarding floor and disembarking floor are the floor where the call was made and the destination floor, respectively. As described above, the security signal is a signal that is given when the user does not want fellow passengers to know the destination floor. The user can set whether or not to give the security signal. When the security signal is given, the destination floor indicator light is turned off, so that fellow passengers other than the user cannot know the user's destination floor, which prevents, for example, fellow passengers from knowing the floor on which the user lives. The user ID is an ID given to a user and can be used to identify the user.

[0024] FIG. 3 is a diagram showing the hardware configuration of the control device 100. As shown in FIG. The illustrated control device 100 has a processor 11 such as a CPU (Central Processing Unit) that controls each part through the execution of a program, an internal memory 12 in which system data and internal data are stored, an external memory 13 as an auxiliary storage device, and a communication module 14 used for communication with external devices.

[0025] The processor 11 executes programs such as an OS (operating system) and application software. In this embodiment, the internal memory 12 is a semiconductor memory. The internal memory 12 has a ROM (Read Only Memory) in which a BIOS (Basic Input Output System) and the like are stored, and a RAM (Random Access Memory) used as a main storage device. The processor 11 uses the RAM as a work space for programs. The external memory 13 is a storage such as a hard disk drive (HDD) or a solid state drive (SSD), and stores firmware, application software, and the like. The communication module 14 is a communication interface for communicating with the car 200 and the platform terminal 300.

[0026] <Explanation of indicator light control> Next, the operation of the operation control unit 110 to control the indicator light of the destination floor in the car 200 will be described in detail. FIG. 4 is a flowchart illustrating a case where the operation control unit 110 controls the indicator lights of the destination floors in the car 200. A user requests a new call by holding an ID card or a portable terminal device over the card reader 320 of the hall terminal 300 (S401). The request for the new call is sent to the operation control unit 110, and the destination floor registration processing unit 113 of the boarding hall registers the new call (S402). As a result, predetermined information such as that shown in FIG. 2 is registered. The indicator light control unit 114 determines whether or not a security signal is included in the information of the new call (S403). As a result, if it is included (YES in S403), the indicator light control unit 114 performs control to turn off the indicator light of the destination floor in the elevator 200 as a security operation. At this time, the indicator light control unit 114 also stores the user ID (S404). Note that, if there is a fellow passenger, the indicator light of the destination floor registered by the fellow passenger is turned on. On the other hand, if it is not included (NO in S403), the security operation is not performed, and the indicator light control unit 114 performs normal control to turn on the indicator light of the destination floor in the elevator car 200 (S405).

[0027] <Detailed Description of Operation of Notification Unit 116> Next, the operation of the notification unit 116 will be described in detail. FIG. 5 is a flowchart illustrating a case where the notification unit 116 notifies a user in the car 200 of a destination floor. A user requests a notification by holding an ID card or a mobile terminal device over the card reader 220 in the car 200 (S501). The notification request is sent to the operation control unit 110, and the notification unit 116 confirms the user ID (S502). That is, the notification unit 116 acquires the user ID via the card reader 220 provided in the car 200, confirms the user, and notifies the destination floor. In this case, as described in S404 of FIG. 4, the user ID is acquired in advance via the card reader 320 installed at the elevator landing. The notification unit 116 verifies the user by checking against the user ID acquired via the card reader 220 provided in the car 200. As a result, if the user ID is confirmed (YES in S502), the notification unit 116 notifies the user of the destination floor by turning on the indicator light of the destination floor for a predetermined period of time (S503). On the other hand, if the user ID cannot be confirmed (NO in S502), the notification unit 116 sounds a buzzer and does not notify the destination floor (S504).

[0028] The method in which the notification unit 116 notifies the user of the destination floor in the car 200 is not limited to the above-mentioned case. For example, the notification unit 116 can notify the user by sound. Specifically, when the car 200 stops at the destination floor of the user, a predetermined sound is sounded, and when the car 200 does not stop at the destination floor of the user, a different predetermined sound is sounded. Furthermore, the notification unit 116 can notify the user by displaying the user ID on a display device installed in the elevator 200. Specifically, a liquid crystal display device or the like is provided in the elevator 200, and when the elevator 200 stops at the destination floor of the user, the user ID is displayed on the liquid crystal display device, and when the elevator 200 does not stop at the destination floor of the user, another message is displayed. As the other message, for example, a message such as "will not stop" may be displayed, or an error message may be displayed.

[0029] <Explanation of the operation panel 210> FIG. 6 is a diagram showing an example of the operation panel 210. As shown in FIG. The illustrated operation panel 210 includes a button 211 and a floor number display unit 212 . The illustrated buttons 211 include a destination floor button 211a and an open / close button 211b. Here, the car 200 can stop at each floor from the first floor to the fifth floor, and users can move between these floors. Normally, when a user presses the destination floor button 211a, an indicator light built into the destination floor button 211a lights up. On the other hand, during the above-mentioned security operation, the indicator light is turned off. The floor on which the car 200 is currently located and the direction of ascent and descent are displayed by an arrow in the floor number display unit 212. Here, it is shown that the car 200 is currently located on the third floor and is moving in an ascending direction.

[0030] <Control when passengers are riding together> On the other hand, when a passenger other than the user boards the vehicle, even if the destination floor indicator light is turned off, if the user gets off at the destination floor first, the passenger will still know the destination floor. Therefore, when there is a fellow passenger other than the user riding in the car 200, the car control unit 115 performs control so that the fellow passenger does not know the destination floor of the user. Specifically, the following control is possible.

[0031] (1) The vehicle will stop at a floor other than the passenger's destination floor and allow the passenger to disembark. That is, the elevator control unit 115 registers a dummy floor as a floor other than the destination floor of the user and makes the user get off, so that the original destination floor is not known. In this case, the dummy floor is registered by the user pressing the button of the destination floor. If there is a fellow passenger, the indicator light of the destination floor registered by the fellow passenger is turned on. Therefore, if the user gets off before the fellow passenger, the user can sense this. In this case, the user registers a dummy floor. Note that the indicator light of the dummy floor is turned on. Then, the elevator control unit 115 performs control to pass the original destination floor. After the user gets off at a dummy floor other than the destination floor, he or she gets back on the elevator 200 and heads for the original destination floor. Note that the elevator control unit 115 can also automatically register the dummy floor. In this case, the user does not register the dummy floor of his or her own will, so there are cases where the user is not aware that the dummy floor has been registered. Therefore, in order to encourage passengers to disembark at the dummy floor, the above-mentioned methods of notifying passengers by sound or displaying the user ID on a display device may be used in combination.

[0032] (2) Turn off the floor display that shows the current floor. In this case, the car control unit 115, for example, turns off the floor displayed on the floor number display unit 212 in Fig. 6. As a result, even if the user gets off at the destination floor first, the passengers cannot know at which floor the user got off.

[0033] In addition, the car control unit 115 can choose not to perform the controls (1) and (2) when the fellow passenger gets off before the user. That is, in this case, the fellow passenger is not in the car 200 when the user gets off, so the fellow passenger does not know the user's destination floor. Therefore, it is not necessary to perform the controls (1) and (2) above. Since the car control unit 115 knows the destination floors of both the user and the fellow passenger, it can determine whether or not to use the controls (1) and (2) above by comparing the destination floor of the user who has registered the destination floor information to which a security signal has been added with the destination floor of the fellow passenger.

[0034] According to the above-mentioned embodiment, it is possible to provide an elevator control device, an elevator control method, and an elevator control system that can turn off the destination floor indicator light in a simpler manner without the need to attach a security button to the car as in the conventional technology. Also, in the conventional technology, the user needs to keep pressing the security mode operation button during security operation, but according to the above-mentioned embodiment, such an operation is not necessary. Also, in the conventional technology, if the user accidentally releases the security mode operation button, the security operation is canceled, but this does not happen in the above-mentioned embodiment.

[0035] <Explanation of elevator control method> The above-described processes performed by the elevator control device 100 are realized by the cooperation of software and hardware resources. That is, the processor in the computer provided in the control device 100 loads the software for realizing each of the above-described functions into memory, executes it, and realizes each of these functions. Therefore, the processing performed by the control device 100 can be considered as an elevator control method that controls the turning on and off of an indicator light that displays the user's destination floor inside the car, in which the processor executes a program recorded in the memory to obtain information on the destination floor to which a security signal is attached, and when the security signal is obtained, controls the turning off of the indicator light for the destination floor and controls the operation of the car.

[0036] Although the present embodiment has been described above, the technical scope of the present invention is not limited to the scope described in the above embodiment. It is clear from the claims that various modifications and improvements to the above embodiment are also included in the technical scope of the present invention. [Explanation of symbols]
