Description

  TECHNICAL FIELD The present invention relates to an elevator voice call registration device and an elevator voice call registration method in which an elevator user can register a destination floor by voice, and more particularly to a through floor where a passenger can get on and off by a two-way door. Considering application to a two-way door elevator that needs to be registered as a floor.

  In a two-way door elevator in which doors serving as entrances and exits are provided in two directions of the cab, there is a conventional technique related to opening / closing control on a through floor corresponding to a floor that can be boarded and exited by the two-way door (for example, Patent Literatures 1 to 3).

  Patent Document 1 discloses a technique for minimizing the elevator from being stopped on the through floor and giving priority to the transportation of the user who gets on the floor.

  Moreover, patent document 2 is disclosing the technique which makes passenger boarding / alighting smoothly by giving priority to boarding / alighting of a disabled person's destination floor call using a wheelchair etc.

  Furthermore, Patent Document 3 aims to reduce the manufacturing cost by diverting a common one-way door elevator hall operation panel to two halls on the through floor for a two-way door elevator. The technology is disclosed.

JP 2009-215031 A Japanese Patent Laid-Open No. 11-189375 JP 2004-43086 A

However, the prior art has the following problems.
The opening / closing operation of the elevator doors on the through floor cannot be opened and closed at the same time due to legal regulations, and it is necessary to open and close the doors one by one. For this reason, when registering a through floor as a destination floor, it is necessary to specify whether the door that opens and closes to get on and off is the front or the back.

  In a two-way door elevator, when a push button type call registration device is applied to register a destination floor as a through floor, even if the destination floor is the same floor, the destination floor for the front and the back are different. It is provided as a button and processed like separate floors.

  On the other hand, in a two-way door elevator, when a voice call registration device is applied to register a through floor destination floor, the front and back surfaces are designated as separate destination floors, similar to a push button type call registration device. It is necessary to do. For this purpose, it is necessary to use different audio phrases on the front side and the back side. For example, when the fifth floor is a penetration floor, use of different voice phrases such as “front of the fifth floor”, “back of the fifth floor”, etc. is conceivable.

  However, phrases such as “front of 5th floor” and “back of 5th floor” are difficult for the first-time user to imagine, and it is difficult to register the destination floor by voice, regardless of the user who knows this usage. It is done.

  In addition, in contrast to the conventional “5th floor” voice generated for registration, the “front of the 5th floor” and the “back of the 5th floor” have a problem that the phrase becomes longer and the accuracy of voice recognition is lowered.

  In addition to the above method, voice call registration devices are individually installed on the front side and the back side of the car room, and the front destination floor registration is the front-side voice call registration device, and the rear destination floor registration is By using the voice call registration device on the back side, a method of designating the front and back sides as separate destination floors can be considered. In this method, if the fifth floor is a penetration floor, the voice call registration device on the side to be registered may pronounce “5th floor”.

  However, installing two voice call registration devices leads to an increase in cost. Also, in terms of operation, it is necessary for the user to move to each door side and perform destination floor registration. Furthermore, if the voice for registration is loud, both the front and back voice call registration devices may register the destination floor.

  For the above reasons, it is difficult to install a voice call registration device in a two-way door elevator with a through floor. Further, each of Patent Documents 1 to 3 described above includes a configuration for registering a destination floor by a user and a configuration for determining whether or not the destination floor is a through floor. However, none of Patent Documents 1 to 3 disclose a technique for determining whether a destination floor is a through floor by voice.

  The present invention has been made to solve the above-described problems, and is a two-way door elevator, and even when a through floor exists, the destination floor of the through floor can be easily voiced from within the car. Another object of the present invention is to provide an elevator voice call registration device and an elevator voice call registration method that can be registered with high accuracy.

In the example of FIG. 1, the first floor is a through floor having entrances in both the front side and the back side, and the second to fourth floors are floors having entrances on either the front side or the back side. Show.

  In such a two-way door elevator, a user whose destination floor is the first floor, which is a through floor, needs to designate either a front door or a rear door. And in this Embodiment 1, it is based on FIG. 2, FIG. 3, Table 1, and Table 2 in detail about the method of designating one of two doors easily with a voice in a penetration floor. explain.

  FIG. 2 is a diagram showing an overall configuration of functional blocks of the elevator voice call registration device according to Embodiment 1 of the present invention. The elevator voice call registration device according to the first embodiment shown in FIG. 2 includes an elevator control panel 10, a voice call registration unit 20 installed in the car 1, and a transmission cable 30 that connects the two. ing.

  The elevator control panel 10 has a built-in control unit 11 including a CPU and a memory. On the other hand, the voice call registration unit 20 is installed in the car 1 and has a microphone 21, a voice acquisition unit 22, a voice recognition unit 23, a call registration unit 24, a notification control unit 25, a notification unit 26, a storage unit 27, A receiving unit 28 is provided. In the present invention, a collective term for the microphone 21, the voice acquisition unit 22, the voice recognition unit 23, the call registration unit 24, the notification control unit 25, and the notification device 26 is referred to as a voice recognition processing unit.

  The control unit 11 in the elevator control panel 10 and each of the call registration unit 24 and the reception unit 28 in the voice call registration unit 20 are connected by a transmission cable 30. The elevator control panel 10 performs control such as elevator lifting / lowering operation and door opening / closing operation based on the calculation of the control unit 11.

  The voice call registration unit 20 has a function for an elevator user to perform call registration by voice. Then, the voice call registration unit 20 transmits the destination floor registration information registered by the voice call to the control unit 11 using the transmission cable 30. On the other hand, the control unit 11 receives the destination floor registration information from the voice call registration unit 20 to register the destination floor of the elevator, and actually controls the raising / lowering of the car and the door opening / closing.

  The microphone 21 in the voice call registration unit 20 is provided in the car 1 for voice input. A user who wants to register a destination floor by voice speaks the destination floor and inputs voice information from the microphone 21. The audio acquisition unit 22 takes in audio information input from the microphone 21.

  The voice recognition unit 23 manages a voice recognition function. The voice recognition unit 23 performs predetermined voice recognition processing on the voice information acquired via the voice acquisition unit 22.

  Specifically, the voice recognition unit 23 determines whether the acquired voice information matches with any of the registered voice information registered in advance in the storage unit 27 under a predetermined condition. Then, when there is registered voice information that matches under a predetermined condition, the voice recognition unit 23 specifies a destination floor corresponding to the voice information.

  Further, the voice recognition unit 23 determines whether or not the destination floor specified corresponding to the voice information is a through floor based on the door type information by floor stored in the storage unit 27 in advance. . And the voice call registration part 20 in this Embodiment 1 confirms whether any door is opened with respect to a user, when a destination floor is a penetration floor.

  That is, the elevator voice call registration device according to the present invention acquires the voice information of the destination floor in the same manner as the normal voice input as the first stage, and when the acquired destination floor is a through floor, As a second stage, a technical feature is to perform a two-stage process in which which door is to be opened is confirmed by a voice response from the user.

  Therefore, for confirmation in the second stage, first, the voice recognition unit 23 transmits a notification command for confirming “which door to open” to the notification control unit 25. And the notification control part 25 which received notification instruction | command performs the alerting | reporting for encouraging the audio | voice answer which specifies which door of a penetration floor is opened with respect to a user via the alerting | reporting device 26. FIG.

  The alarm device 26 can be composed of a liquid crystal display, an announcement device, or the like. Then, the notification device 26 receives display data, sound data, or both data as notification related to the voice call registration to the user from the notification control unit 25 and notifies the user in the car 1. .

  For example, as voice data or display data to be notified to confirm "whether one of the doors is opened", "please pronounce high when registering this side, pronounce yes when registering that side", etc. Conceivable.

  The voice acquisition unit 22 acquires a voice response from the user with respect to the notification from the notification device 26 in the second stage via the microphone 21. Then, the voice recognition unit 23 performs a predetermined voice recognition process on the voice information acquired through the voice acquisition unit 22 in the second stage in the same manner as when registering the destination floor.

  Further, the voice recognition unit 23 determines whether the user's response is “high” or “no”, for example, so that the door that the user wants to specify on the penetration floor is the front or the back. Is identified.

  Finally, when the destination floor recognized in the first stage is not a penetration floor, the voice recognition unit 23 generates the recognized destination floor as it is as destination floor registration information. On the other hand, when the destination floor recognized in the first stage is a penetration floor, the voice recognition unit 23 considers the voice recognition result in the second stage for the destination floor recognized in the first stage. The destination floor specifying either the front side or the back side is generated as destination floor registration information.

  The call registration unit 24 transmits the destination floor registration information generated by the voice recognition unit 23 to the control unit 11 in the elevator control panel 10 via the transmission cable 30 and registers the destination floor in the control unit 11. Make it.

  When the call registration unit 24 finishes transmitting the destination floor registration information, the voice recognition unit 23 notifies the user that the destination floor has been registered via the notification control unit 25 and the notification device 26. For example, if the destination floor is not a through floor, “Notification of XX floor” may be considered as specific notification contents. If the destination floor is a through floor, Could be registered ".

  In addition, the content notified from the notification device 26 may be voice recognition start guidance for notifying the start of voice recognition or voice recognition end guidance for notifying the end of voice recognition. As these guidances, in the case of an announcement based on audio data, it may be possible to apply a series of sounds such as “beep” or a double tone such as “beep”.

  The reception unit 28 can receive floor type door type information from the control unit 11. This will be described in detail in the second embodiment.

  FIG. 3 is a flowchart showing a series of processes by voice call registration unit 20 in the first embodiment of the present invention. Details of destination floor registration by the voice call registration unit 20 will be described with reference to FIG. Hereinafter, in FIG. 3, all the operating subjects will be described as the voice call registration unit 20.

  First, when the call registration unit 20 detects the door fully open state based on the information received from the elevator control panel 10 in step S101, it notifies the voice recognition start guidance in step S102. In step S103, the voice call registration unit 20 starts voice recognition.

  After starting the voice recognition, in step S104, the voice call registration unit 20 determines whether or not the voice is input. If it is determined that the voice is input, the process proceeds to step S108, where the voice is input. If it is determined that there is no, the process proceeds to step S105.

  When the process proceeds to step S105, the voice call registration unit 20 determines whether or not a certain time has elapsed after the door is closed, and when the certain time has not elapsed, the process returns to step S104. If the predetermined time has elapsed, the process proceeds to step S106.

  If the process proceeds to step S106, the voice call registration unit 20 ends the voice recognition. Further, in step S107, the voice recognition end guidance is notified, and the series of processes ends.

  On the other hand, if it is detected in step S104 that voice has been input and the process proceeds to step S108, the voice call registration unit 20 recognizes the destination floor by voice recognition as the first stage. The destination floor recognized in step S108 corresponds to the “designated destination floor” identified by the first-stage recognition process.

  Furthermore, in step S109, the voice call registration unit 20 determines whether the destination floor recognized in the previous step S108 is a through floor. If the call registration unit 20 determines that the destination floor is a penetration floor, the voice call registration unit 20 proceeds to step S110, performs the second stage voice processing, and determines that the destination floor is not a penetration floor. Proceeding to step S114, the destination floor registration information is created.

  When it is determined that the destination floor is a penetration floor and the process proceeds to step S110, the voice call registration unit 20 performs door direction confirmation notification on the penetration floor as a second step, and voices the user. Encourage answers.

  In step S111, the voice call registration unit 20 determines whether or not a voice is input as an answer by the user. If it is determined that a voice is input, the process proceeds to step S113, where the voice is input. If it is determined that there is not, the process proceeds to step S112.

  When the process proceeds to step S112, the voice call registration unit 20 determines whether or not a certain time has elapsed. When the certain time has not elapsed, the process returns to step S111 and the certain time has elapsed. If YES in step S106, the flow advances to step S106 to perform speech recognition end processing.

  On the other hand, when the process proceeds to step S113, the voice call registration unit 20 recognizes the front and back surfaces by performing voice recognition based on the voice response from the user, and proceeds to step S114.

  When the process proceeds to step S114 after passing through step S109 or step S113, the voice call registration unit 20 creates destination floor registration information and transmits the destination floor registration information to the elevator control panel 10. . As described above, when the destination floor is not a through floor, the process proceeds to step S114 after step S109, so that the destination floor registration information is created only by the first stage speech recognition processing, and the destination floor is a through floor. In this case, after performing the second stage speech recognition process in steps S110 to S113, the process proceeds to step S114, so that the destination floor registration information is obtained as a result of the two stage speech recognition process of the first stage and the second stage. Created.

  Thereafter, the voice call registration unit 20 terminates the voice recognition in step S115, and further notifies the destination floor registration result in the car 1 in step S116, and then returns to step S101 to again wait for the door to fully open. Become.

  Table 1 shows an example of registered voice information stored in the storage unit 27 in order to determine the destination floor by voice recognition.

  The registered audio information can register a plurality of audio information for each floor using the floor as a key. In the example of Table 1, the case where three types of audio information are registered as the audio information 1 to 3 is illustrated. The voice recognition unit 23 determines whether the voice information input based on the user's utterance matches with any one of the voice information 1 to 3 stored in the storage unit 27 under a predetermined condition. If they match, the floor is determined as the destination floor. Here, the predetermined condition corresponds to, for example, determining whether or not the degree of coincidence obtained quantitatively is equal to or greater than an allowable threshold value.

  Table 2 collectively shows an example of door type information by floor stored in the storage unit 27 in order to determine whether or not the destination floor recognized in the first stage is a through floor.

  The door-specific information for each floor defines whether or not there is a front door and a rear door using floor data as a key. Therefore, the voice recognition unit 23 can determine that the floor is a through floor when both the front door and the rear door are set as “present” as the door type information for each floor regarding the destination floor recognized in the first stage. . The floor-specific door type information exemplified as Table 2 corresponds to the configuration of each floor shown in FIG. 1, and the first floor is set as a through floor.

  As described above, according to the first embodiment, there is provided a configuration capable of executing two-stage audio processing by the first stage and the second stage. As a result, the user can designate the destination floor by voice in the same manner as normal voice input as the first step without being aware of whether or not his destination floor is a through floor. Furthermore, when the destination floor is a penetration floor, as a second stage, the user follows the notification for prompting the voice answer specifying which door of the penetration floor is to be opened. Can be specified.

  Therefore, it is possible for the user to easily register the destination floor including the penetration floor by voice, and for the apparatus side, it is possible to suppress a decrease in voice recognition accuracy by one apparatus. Benefits that can be obtained. As a result, an elevator voice call registration device that is a two-way door elevator and can easily and accurately register a destination floor of a through floor from within a car even when there is a through floor is provided. realizable.

  The receiving unit 28 according to the second embodiment has a function capable of receiving the floor-specific door type information from the control unit 11. That is, the receiving unit 28 receives the floor-specific door type information received from the control unit 11 from the information stored in the storage unit 27 in advance. It is possible to switch to type information.

  FIG. 4 is a flowchart showing a series of processing steps for switching the door type information by floor by the voice call registration unit 20 according to the second embodiment of the present invention. Hereinafter, in FIG. 4, all the operating subjects will be described as the voice call registration unit 20.

  First, in step S201, the voice call registration unit 20 checks whether or not the floor-specific door type information has been received from the control unit 11 when performing the penetration floor determination. If it has been received, the process proceeds to step S202, and the voice call registration unit 20 uses the floor type door type information received from the control unit 11 to determine whether or not it is a through floor. . On the other hand, if it has not been received, the process proceeds to step S203, and the voice call registration unit 20 determines whether the floor type door type information stored in advance in the storage unit 27 is a through floor or not. use.

  FIG. 5 is a flowchart showing a series of processes for receiving the door type information by floor by the voice call registration unit 20 according to the second embodiment of the present invention. Hereinafter, in FIG. 5, all the operating subjects will be described as the voice call registration unit 20.

  In step S <b> 301, the voice call registration unit 20 checks whether the floor-specific door type information is received from the control unit 11. When the floor-specific door type information is received, the process proceeds to step S302, where the voice call registration unit 20 temporarily stores the received floor-specific door type information, and then ends the series of processes. If the floor-specific door type information is received, the series of processes is terminated as it is.

  When the voice call registration device is turned off and then turned on again, the voice call registration unit 20 discards the floor-specific door type information received from the control unit 11 and temporarily stored. The floor type door type information is set to an unreceived state. As a result, once the door-specific door type information is received from the control unit 11 and the floor-specific door type information is switched when determining whether or not it is a through floor, the voice call registration device By turning the power off and then on, the information used for the determination can be returned to the initial door type information stored in the storage unit 27 in advance.

  As described above, according to the second embodiment, the floor-specific door type information used for determining whether or not it is a through floor can be set from the elevator control panel as necessary. As a result, even when one door on the through floor is temporarily unavailable, appropriate door type information by floor can be temporarily reset.
