Description

    Technical Field
  • The present invention relates to an elevator landing call register that are placed at a landing hall and usable for both physically handicapped persons and able-bodied persons.
    • Background Art
  • A conventional call register is equipped with means for exercising a speech recognition function by detecting existence of a user. For example, according to an elevator landing register disclosed in Patent Document 1, when call registration is made by a microphone set in an elevator hall, human detecting means detects whether a user of an elevator stands in front of the microphone, and speech recognizing means is made operable only when it is detected by the human detecting means that an elevator user stands in front of the microphone. Furthermore, according to an elevator calling register disclosed in Patent Document 2, a call registering speech from a user is input by a microphone only when human detecting means detects that a person stands in front of the microphone. However, in a case where the human detecting means does not detect existence of any person, even if there is a speech input to the microphone, it is judged as a noise and the recognition processing operation is not operated, thereby preventing malfunction.

    [Best Modes for carrying out the Invention]
  • The present invention relates to a elevator landing call register set at an elevator landing hall, and relates to a landing call register equipped with a speech recognizing device with which an elevator user needing speech recognition function registers a destination floor by speech.
    Each embodiment of the present invention will be described hereunder with reference to the drawings. In the figures, the same reference numerals represent the same or corresponding portions.
    • Embodiment 1
  • Fig. 1 is a diagram showing the overall construction of an elevator landing call register according to a first embodiment of the present invention.
    In Fig. 1, one or more elevator landing call registers 1 according to an embodiment 1 of the present invention are set up at each landing hall. Each elevator landing call register 1 comprises a call registering button 11, a speech input device 12, a speech recognizing device 13, a sound output device 14, a call control unit 15, etc., and each of these elements is connected to the elevator control device 2 through the communication path 3.
  • Next, the respective functions of the call registering button 11, the speech input device 12, the speech recognizing device 13, the sound output device 14, the call control unit 15 and the elevator control device 2 will be described.
    The call registering button 11 comprises call upward and downward buttons on intermediate floors as in the case of the normal call registering button, comprises a call upward button on the lowermost floor, and comprises a downward button on the uppermost floor. The operation procedure to be executed by an elevator user requiring speech recognition is changed from the operation to be normally executed on the upward or downward button of the call registering button 11 (for example, the button is once operated for one second or less), whereby the operation based on the user and the normal operation can be discriminated from each other.
    For example, when the user concerned pushes the call registering button 11 for a long time (for example, one second or more), pushes the call registering button 11 at plural times (for twice or more) within a fixed time, or strongly pushes the call registering button 11, a direction call of the call registering button 11 operated on that floor is input, and also the speech input device 12 and the speech recognizing device 13 described below function respectively.
    That is, even when an elevator user which does not need speech recognition normally operates the call registering button 11, a direction call of the call registering button operated on that floor is input, however, the speech recognition function is not enabled.
  • The speech input device 12 is enabled only when the call control unit 15 detects that an elevator user who needs the speech recognition function carries out a different operation from the normal operation on the call registering button 11, and a speech (a destination floor name) of the user is input through a microphone or the like. That is, only when the operation different from the normal operation (for example, once operation for one second or less) is carried out on the call registering button 11, the input (destination floor name) of the speech of the user is accepted.
  • The speech recognition device 13 is enabled only when the call control unit 15 detects the operation of the call registering button 11 which is different from the normal operation as in the case of the speech input device 12, and it recognizes the destination floor based on the speech which is input by the speech input device 12.
    That is, the speech recognition device 13 recognizes a speech only when the elevator user needing the speech recognition function carries out a predetermined operation on the call registering button 11, and recognizes the destination floor on the basis of the user' s speech input from the speech input device 12.
  • When the normal operation (pushing for one second or less) is carried out on the call control unit 15, the call control unit 15 reports the name of the floor having the call registering button 11 concerned set thereon and the call direction (upward or downward) through the communication path 3 to the elevator control device 2. In addition, when the operation different from the normal operation is carried out on the call registering button 11, the call control unit 15 reports the destination floor recognized on the basis of the speech of the speech recognition device 13 to the elevator control device 2. That is, when the call registering button 11 is operated in a predetermined procedure different from the normal procedure, the functions of the speech input device 12 and the speech recognition device 13 are enabled, and the destination floor recognized by the speech recognition device 13 is reported to the elevator control device 2.
    Furthermore, the call control unit 15 records the existence or non-existence of the destination floor, and it has a function of collating the direction of the operated call registering button 11 with the existence or non-existence of the destination floor recognized by the speech recognition device 13 and the destination direction to the destination floor, and then reporting to the elevator control device 2.
  • With the above construction, only when the elevator user needing the speech recognition function operates the call registering button 11 in the predetermined procedure, the call control unit 15 enables the speech recognition function, and recognizes only the speech of the requiring user, so that mis-recognition can be suppressed. Furthermore, the elevator user who does not need the speech recognition function is not required to utter the destination floor by using the cumbersome speech recognition device 13, and thus there can be provided the landing call register 1 which has high convenience and reliability to any user.
  • The speech recognition device 13 and the call control unit 15 may be constructed by a microcomputer, a memory, etc. Furthermore, a memory may be contained in a microcomputer. Furthermore, the functions of parts of the speech input device 12 and a sound output device 14 described later may be contained in a microcomputer. Accordingly, the landing call register can be constructed by using more general parts, and thus the cost can be reduced.
    • Embodiment 2
  • In the embodiment 1, only when it is detected that the call registering button 11 is operated by the elevator user needing the speech recognition, the speech recognition function of the speech recognition device 13 is enabled, and the destination floor which is recognized on the basis of the speech of the user by the speech recognition device 13 is reported to the elevator control device 2 through the communication path 3 to register the recognized destination floor.
    On the other hand, in the second embodiment 2, in addition to the above operation, necessary sound information is taken out from the sound information stored in the call control unit 15 of Fig. 1, and the sound output device 14 reports the completion of the call registration of the destination floor to the user with a voice (for example, "OO floor accepted") or a response sound (for example, "piche") from a speaker. Accordingly, the elevator user needing the speech recognition, for example, a vision-impaired person can check with sounds that the speech uttered by the person concerned is correctly recognized, and thus he/she feels reassured.
  • The call control unit 15 collates the recognized destination floor with the stored floor destination floors so as to judge whether the recognized destination floor exists. If the recognized destination floor does not exist, it is reported to the user from the sound output device 14 that the destination floor concerned does not exist. At this time, the call control unit 15 takes out stored sound information, for example, "the recognized floor is not registrable, and please utter once again", a response sound "piche piche" or the like, and outputs it from the sound output device 14. Accordingly, the vision-impaired person recognizes it with the sound that the uttered floor name cannot be registered and thus can retry to utter or the like, and thus the convenience can be enhanced.
    • Embodiment 3
  • In the embodiment 1, only when it is detected that the call registering button 11 is operated by the elevator user who needs the speech recognition, the speech recognition function of the speech recognition device 13 is enabled, and the destination floor recognized on the basis of the utterance of the user by the speech recognition device 13 is reported through the communication path 3 to the elevator control device 2.
    On the other hand, the call control unit 15 of this embodiment 3 checks whether the direction of the operated call registering button 11 is coincident with the destination direction to the destination floor recognized by the speech recognition device 13, and further checks whether the recognized destination floor exists or not. If the destination floor exists and both the directions are coincident with each other, the destination floor is reported to the elevator control device 2. However, if both the directions are not coincident with each other, the recognized floor destination is judged as being invalid, and nothing is reported to the elevator control device 2. Accordingly, only the matched destination floor is reported, and thus there can be provided the landing call register 1 having a high recognition rate. Therefore, the convenience for the users can be enhanced.
  • Furthermore, the call control unit 15 may instruct the sound output device 14 to emit a sound such as an utterance of "please utter once again" or the like, a warning sound "piche piche" or the like, and report from the sound output device 14 to the user. Accordingly, the user can know whether the destination floor uttered by himself/herself is correctly registered, and if he/she can known that it is not registrable, he/she can retry the utterance and repeat the utterance until the speech recognition device 13 correctly recognizes the utterance. Accordingly, there can be provided the landing call register 1 that puts the user at his/her ease and has high recognition rate. Therefore, the convenience can be enhanced.
  • Fig. 2 is a flowchart showing the operation of an elevator landing call register according to the embodiments 1 to 3.
    The operation of the elevator landing call register according to the embodiments 1 to 3 will be described hereunder with reference to Fig. 2.
    First, the normal operation by an elevator user who does not need the speech recognition device, for example, an able-bodied person will be described.
    First, the landing call register 1 is set to a standby state for the operation of the call registering button 11 (S1). When the call registering button 11 pushes for a normal short time (for one second or less), the call control unit 15 judges that the operation of the call registering button 11 is normally operated (S2), and it reports the floor of the operated calling registering button 11 and the pushed call direction (upward, downward) through the communication path 3 to the elevator control device 2 and registers the call (S3).
    The elevator control device 2 allocates an elevator in accordance with the reported floor and call direction (upward, downward) (S3). When the elevator allocation is completed and the call registration is released, the landing call register 1 is set to a standby state for the call registration button 11 again (S1).
  • Next, the operation by an elevator user who needs the speech recognition device, for example, a physically handicapped person will be described.
    When a physically handicapped person operates the button according to the predetermined procedure, that is, when the operation of the call registering button 11 is a special operation different from the normal operation (for example, long-time pushing for one second or more, pushing at plural times within a fixed time, strongly pushing, or the like), the speech recognition device 13 takes out necessary sound information (in this case, "please utter destination floor" or a response sound "pi") or the like, and outputs the sound to the sound output device 14, whereby the physically handicapped person is informed of a using manner or that the device has responded (S4).
    The speech recognition device 13 is set to a standby state for an input from the speech input device 12 (S5). When utterance of a destination floor is input (S6), the speech recognition device 13 recognizes the input concerned (S7). For example, when "fourth floor" is input, the speech recognition device 13 recognizes "fourth floor", and the call control unit 15 judges whether the direction (upward, downward) of the call registering button 11 operated in S2 is coincident with the destination direction of the recognized floor (S8).
    If no speech input can be detected during a fixed time or more, the function of the speech recognition function is disabled, and a standby state for the normal operation of the call registering button is set (S6).
    If the destination direction of the recognized floor and the direction of the operated call registering button 11 are not coincident with each other, the sound information stored in the call control unit 15, for example, "please utter once again" or a response sound "piche piche" is taken out and output from the sound output device 14 (S9) and then the standby state is set again (S5).
    If the recognized floor destination direction and the direction of the call registering button 11 are coincident with each other, the call control unit 15 reports the destination floor (fourth floor in this case) to the elevator control device 2 through the communication path 3 (S10).
    When no recognized destination floor exists (S11), the call control unit 15 reports to the landing call register 1 that the destination floor is a non-existing floor. At this time, the call control unit 15 takes out the stored sound information, for example, "please utter once again" or a response sound "piche piche", outputs it from the sound output device 14 (S9), and is set to the standby state again (S5).
    When the destination floor recognized by the call control unit 15 exists (S11), the elevator controller 2 registers the destination floor, allocates an elevator on the basis of the reported destination floor (S12), and reports the registration concerned to the landing call register 1. The call control unit 15 takes the stored sound information, for example, "fourth floor registered", "fourth floor accepted" or a response sound "piche", and outputs it from the sound output device 14 (S13).
  • With respect to the stored sound information, plural segments such as "four" and "floor accepted" are connected to each other and then output, whereby the same phrases can be repetitively used. Therefore, the memory capacity for storing the sound information can be reduced, and thus the cost can be reduced.
    Furthermore, when no speech input is detected during a fixed time or more after the call registering button 11 is once operated according to the predetermined procedure (the operation of the call registering button by a physically handicapped person) different from the normal procedure, the function of the speech recognition is disabled again, and the standby state for the normal call registering button is set. Accordingly, the convenience can be enhanced without disturbing the convenience for able-bodied persons.
  • In the above embodiment, the landing call register 1 itself records the existence or non-existence of the destination floor, and collates the existence or non-existence of the recognized destination floor and the destination direction with the direction of the operated call registering button. However, even when the elevator control device 2 receiving a report of the recognized destination floor from the landing call register 1 collates the existence or non-existence of the recognized destination floor and reports to the landing call register 1, the same effect can be achieved.
    • [Industrial Applicability]
  • The present invention is suitably used as a landing call register for an elevator, particularly, an elevator usable for both physically handicapped persons and able-bodied persons.
