Patent Documents 2 to 5 describe techniques for remotely operating a control target using a remote control device that uses voice recognition.

JP-A-6-179580 Japanese Patent Laid-Open No. 5-7385 JP 2000-305586 A JP 2001-318689 A JP 2004-96520 A

  In the hall call registration device described in Patent Document 1, another vehicle is detected by the photoelectric detector, and the elevator hall call registration is undesirably performed.

  In addition, the above-mentioned Patent Documents 2 to 5 do not show a technique for performing voice recognition to control a mechanical operation that takes a relatively long time, such as an elevator opening / closing operation, while ensuring safety. .

  In the remote control devices described in Patent Documents 2 to 5, it is necessary to operate the operation buttons of the voice recognition remote control device in order to perform voice recognition. Even if the remote control device described in Patent Documents 2 to 5 is applied to control of the operation of the elevator, the remote control device is used for voice recognition when the door closed by the elevator is reopened during the work of loading and unloading the luggage. If the door is not operated immediately in an extremely short time, there is a problem that an accident of interference between the door and the vehicle occurs.

  An object of the present invention is to provide an elevator lifting / lowering control device capable of improving the efficiency of the work for loading and unloading loads while ensuring the safety of the operation of the elevator.

The present invention provides voice information input means for inputting voice information;
Voice recognition means for performing voice recognition of voice information input by the voice information input means;
When the voice information recognized by the voice recognition means is the voice information related to the elevator operation including at least the elevator lifting / lowering operation and the door opening / closing operation, the operation information representing the elevator operation is transmitted corresponding to the voice information. A transmission means;
Receiving means for receiving the operation information transmitted by the transmitting means;
And an elevator lift control device including control means for controlling the operation of the elevator in response to the operation information received by the receiving means.

The present invention further includes storage means for storing a plurality of predetermined voice recognition information in association with one operation of the elevator,
When the voice recognition means determines that the voice information input by the voice information input means matches any one of the plurality of voice recognition information stored in the storage means, the voice recognition information Select the operation information that represents the operation of the associated elevator,
The transmission means transmits the selected operation information.

The present invention further includes storage means for storing one or more predetermined voice recognition information in association with the start and end operations of voice recognition,
When the voice recognition means determines that the voice information input by the voice information input means matches any one of the one or more voice recognition information stored in the storage means, the matched voice recognition A voice recognition operation associated with information is performed.

  Further, the present invention is characterized in that the control means controls the operation of the elevator based on the new operation information received by the receiving means after the operation of the elevator based on the operation information received by the receiving means is completed. To do.

  Further, according to the present invention, when the operation cancel information indicating that the operation is canceled when the control unit is operating the elevator in response to the operation information is received by the reception unit, the control unit cancels the operation of the elevator. It is characterized by that.

  According to the present invention, voice information can be input by voice information input means. The voice recognition unit performs voice recognition of the voice information input by the voice information input unit. When the voice information recognized by the voice recognition means is the voice information related to the elevator operation including at least the elevator up / down operation and the door opening / closing operation, the operation information corresponding to the recognized voice information and representing the operation of the elevator Is transmitted by the transmitting means. The operation information transmitted by the transmitting unit is received by the receiving unit. The operation of the elevator is controlled by control means that responds to the operation information received by the receiving means.

  Therefore, an operator who operates the elevator by inputting voice information using the voice input means (hereinafter sometimes simply referred to as an “operator”), for example, when loading / unloading luggage into the elevator, The elevator operation corresponding to the input voice information can be relatively easily caused to be executed by the elevator simply by inputting the voice information related to the elevator operation including at least the opening / closing operation by the voice information input means. As a result, it is possible to eliminate the trouble of the operator once getting out of the baggage carrying-in / out vehicle and operating the operation buttons of the elevator, and the interruption of the baggage carrying-in / out operation can be prevented. As a result, it is possible to contribute to improving the work efficiency when the operator carries the load into the elevator.

  In addition, even when a problem such as the elevator door closing closes during the work of loading / unloading luggage, the operator can input the voice information indicating the door opening operation using the voice information input means. The elevator door can be opened again. Therefore, the operation of the elevator can be switched relatively easily and quickly as compared with the prior art in which the operation button of the remote control device has to be operated for voice recognition. As a result, it is possible to prevent the occurrence of an interference accident between the door and the vehicle for loading / unloading the luggage during the work of loading / unloading the luggage. Thereby, safety of the operation of the elevator can be achieved. In other words, the elevator can be operated safely.

  According to the invention, the storage means stores a plurality of predetermined voice recognition information associated with one operation of the elevator. When the voice recognition means determines that the voice information input by the voice information input means matches any one of the plurality of voice recognition information stored in the storage means, the voice recognition information Select operation information representing the operation of the associated elevator. The selected operation information is transmitted by the transmission means.

  As described above, since the storage means stores a plurality of pieces of speech recognition information associated with one operation of the elevator, only one piece of speech recognition information is associated with one operation of the elevator. Compared to the stored case, it is possible to increase the voice recognition rate of voice information input by an operator who loads the luggage into the elevator.

  When only one voice recognition information is stored in association with one operation of the elevator, the operator confirms the voice recognition information corresponding to the operation of the elevator in advance and accurately grasps it. However, if a plurality of voice recognition information is stored in association with one operation of the elevator, the operator confirms the voice recognition information in advance and accurately grasps it. There is no need. In other words, the operator can operate the elevator only by inputting voice information associated with the operation content of the elevator. As a result, the operator can operate the elevator with sound that is easy to pronounce, and the convenience of the operator can be improved.

  Therefore, it is possible to save the operator from having to confirm and grasp the voice recognition information for operating the elevator in advance, and to improve the convenience of the operator. In addition, it is possible to smoothly carry out the work of loading and unloading the luggage by the operator, and it is possible to improve the work efficiency of loading and unloading the luggage.

  Further, according to the present invention, the storage means stores one or more predetermined voice recognition information associated with the voice recognition start and end operations. When the voice recognition means determines that the voice information input by the voice information input means matches any one of the one or more voice recognition information stored in the storage means, the matched voice recognition A speech recognition operation associated with the information, specifically, a speech recognition start or end operation is performed.

  Therefore, the voice recognition means performs a voice recognition operation associated with the matched voice recognition information, for example, an elevator lifting operation and a door opening / closing operation input by the voice information input means when the voice recognition is started. Speech recognition of speech information related to at least elevator operation is performed. The voice recognition means does not perform voice recognition of the voice information related to the operation of the elevator when the voice recognition operation associated with the matched voice recognition information, for example, voice recognition is finished.

  As a result, the operator can switch the start and end operations of voice recognition relatively easily. For example, when it is not necessary to operate the elevator, the operator himself / herself can be switched by ending the voice recognition in advance. It is possible to prevent the voice information represented by the voice that is inadvertently uttered from being input by the voice information input means, and the input voice information from being undesirably recognized by the voice recognition means. Therefore, it is possible to prevent the elevator from operating undesirably in response to the elevator operation information corresponding to the voice information input by the voice information input means.

  Further, according to the present invention, after the operation of the elevator based on the operation information received by the receiving unit is completed, the operation of the elevator based on the operation information newly received by the receiving unit is controlled by the control unit. The Therefore, even when new operation information is received by the receiving means during the operation of the elevator based on the operation information first received by the receiving means, the operation of the elevator based on the first received operation information is completed. Until then, the elevator operation based on the new operation information is not started.

  Thus, for example, when operation information for closing the elevator door is received by the receiving means during the operation of opening the elevator door, the operation of the elevator is suddenly switched to an operation undesired for the operator. It is possible to prevent the occurrence of an interference accident between the vehicle for loading and unloading and the door of the elevator. Therefore, safety of the operation of the elevator can be achieved. In other words, the elevator can be operated safely.

  Further, according to the present invention, when the control means receives the operation release information indicating that the operation is released when the elevator is operating in response to the operation information received by the reception means, the reception means receives the operation release information. The operation of the elevator before receiving the operation release information is released by the control means. Therefore, for example, when an operator loads cargo into the elevator, even if voice information of an unwanted elevator operation is erroneously input by the voice information input means, the unwanted elevator operation is relatively easy and quick. Can be released. As a result, it is possible to improve the efficiency of loading and unloading work compared to a case where the operation cannot be canceled during the operation of the elevator.

In the present embodiment, the operator of the remote control unit 2 is assumed to be an operator who drives a vehicle loaded with a load and loads the load into an elevator. When the operator inputs voice information, for example, a word relating to the operation of the elevator, from the microphone 12 of the remote control unit 2, this processing procedure is started, and the process proceeds to step a1. In the following description, a word input from the microphone 12 by an operator may be simply referred to as an “input word”.

  In step a1, the speech processing unit 29 refers to the speech recognition table 40 stored in the storage unit 28 to determine whether or not the input word and the activation word match. Proceed to a2, and if not matched, proceed to step a9. In step a2, the voice processing unit 29 causes the speaker 13 to output, for example, matching voice information “Start voice recognition”. When the matching voice information is output from the speaker 13, the process proceeds to step a3. In step a9, the voice processing unit 29 outputs, for example, non-matching voice information “Sound recognition cannot be activated” from the speaker 13 and ends this processing procedure.

  In step a <b> 3, the operation unit side control unit 17 turns on the recognition lamp 14 based on the match information given from the information processing unit 16. When the recognition lamp 14 is turned on, the process proceeds to step a4. In step a4, the voice processing unit 29 determines whether or not a word is input from the microphone 12. If the word is input, the process proceeds to step a5. If not input, the process proceeds to step a8.

  In step a5, the speech processing unit 29 refers to the speech recognition table 40 stored in the storage unit 28 to determine whether or not the input word and the elevator operation word match. Proceed to step a6, and if not matched, proceed to step a10. In step a6, the voice processing unit 29 causes the speaker 13 to output matched voice information “For example, voice recognition has been performed as an elevator operation word”. When the matching voice information is output from the speaker 13, the process proceeds to step a7.

  In step a7, the operation unit side control unit 17 uses the transmitter 18 to transmit the operation information stored in the storage unit 28 in association with the elevator operation word, which is the voice recognition information determined to match in step a5, to the elevator 18. Transmit to the drive unit 3. If operation information is transmitted to the elevator drive part 3, it will progress to step a8.

  In step a8, the operation unit side control unit 17 determines whether or not a predetermined time, for example, 300 seconds has elapsed, ends the processing procedure if it has elapsed, and proceeds to step a4 if it has not elapsed. Returning, the same processing as described above is performed.

  In step a10, the speech processing unit 29 refers to the speech recognition table 40 stored in the storage unit 28 to determine whether or not the input word and the operation release word match. Proceed to a11. If they do not match, proceed to step a13. In step a11, for example, the matching voice information that “speech recognition has been performed as an operation release word” is output from the speaker 13. When the matching voice information is output from the speaker 13, the process proceeds to step a12.

  In step a12, the operation unit side control unit 17 uses the transmitter 18 to transmit the operation release information stored in the storage unit 28 in association with the operation release word, which is the voice recognition information determined to match in step a10, to the elevator 18. Transmit to the drive unit 3. When the operation release information is transmitted to the elevator drive unit 3, the process returns to step a8 and the same processing as described above is performed.

  In step a13, the speech processing unit 29 refers to the speech recognition table 40 stored in the storage unit 28, and determines whether or not the input word matches the speech recognition end word. If they do match, the process proceeds to step a14, and if they do not match, the process proceeds to step a15. In step a14, the voice processing unit 29 outputs, for example, matching voice information “speech recognition is finished” from the speaker 13 and ends this processing procedure.

  In step a15, the voice processing unit 29 causes the speaker 13 to output non-matching voice information that “speech recognition could not be performed”, for example. When the mismatch audio information is output from the speaker 13, the process returns to step a8 and the same processing as described above is performed.

  FIG. 5 is a flowchart showing a processing procedure of the elevator control unit 22 relating to control of the operation of the elevator. This process is executed by the elevator control unit 22. When the information is received by the receiver 20, this processing procedure is started and the process proceeds to step b1.

If received, the process proceeds to step b2, and if not received, the process proceeds to step b4. In step b2, it is determined whether or not at least one of the car drive unit 23 and the door drive unit 24 is driven. If the car drive unit 23 is driven, the present process is terminated, and the car drive unit 23 and the door drive unit 24 If neither is driven, the process proceeds to step b3.

  For example, when the receiver 20 receives operation information representing the closing operation of the elevator door, it is determined whether or not the car is driven up and down and whether or not the door is opened and closed in step b2. When the raising / lowering driving and the opening / closing driving are not performed, the process proceeds to step b3.

  In step b <b> 3, an elevator drive command corresponding to the operation information received by the receiver 20 is given to the car drive unit 23 or the door drive unit 24. When the driving command is given to the car driving unit 23 or the door driving unit 24, the processing procedure is terminated.

  For example, when the receiver 20 receives operation information indicating the closing operation of the elevator door, in step b3, an elevator driving command corresponding to the closing operation, specifically, a driving signal for closing the door (hereinafter referred to as a driving signal). , Referred to as a “closed drive signal”). When the door driving unit 24 receives a closing drive signal from the elevator control unit 22, the door driving unit 24 applies a predetermined driving force to the door motor in accordance with the closing driving signal. This closes the door.

  In step b4, it is determined whether or not the operation release information transmitted from the remote control unit 2 has been received by the receiver 20, and if received, the process proceeds to step b5, and if not received, this processing procedure is performed. finish. In step b5, it is determined whether or not at least one of the car drive unit 23 and the door drive unit 24 is driven. If it is driven, the process proceeds to step b6, and if it is not driven, this processing procedure is terminated. .

  For example, when the operation release information for canceling the call operation is received by the receiver 20 while the call operation of the elevator is being executed, it is determined in step b5 whether or not the car is driven up and down. When it is driven up and down, the process proceeds to step b6.

  In step b <b> 6, an elevator operation release command corresponding to the operation release information received by the receiver 20 is given to the car drive unit 23 or the door drive unit 24. When the operation release command is given to the car driving unit 23 or the door driving unit 24, the present processing procedure ends.

  For example, when the receiver 20 receives the operation release information for releasing the call operation of the elevator, in step b6, the elevator call operation release command, specifically, a signal for releasing the call operation (hereinafter referred to as the call operation) (Referred to as “call release signal”). When a call release signal is given from the elevator control unit 22, the car drive unit 23 stops supplying driving force to the car drive unit 23 according to the call release signal. As a result, the call operation is released.

  As described above, according to the present embodiment, voice information is input from the microphone 12 of the headset configured integrally with the speaker 13 by an operator who loads and unloads luggage. For example, when voice information related to the operation of the elevator is input from the microphone 12, the information processing unit 16 performs voice recognition of the voice information input from the microphone 12. When the voice information recognized by the information processing unit 16 is voice information related to an elevator operation including at least an elevator lifting operation and a door opening / closing operation, an operation corresponding to the recognized voice information and representing an elevator operation The information is transmitted to the elevator driving unit 3 by the transmitter 18 of the remote operation unit main body 11. The operation information transmitted by the transmitter 18 is received by the receiver 20 of the elevator driving unit 3, and the operation of the elevator is controlled by the elevator control unit 22.

  Therefore, an operator who loads and unloads luggage simply inputs voice information related to the elevator operation including at least the elevator lifting / lowering operation and the elevator door opening / closing operation from the microphone 12, and the elevator corresponding to the input voice information is provided. The elevator can be relatively easily executed by the elevator. Accordingly, it is possible to eliminate the trouble of the operator once getting off the vehicle for loading / unloading the luggage such as a forklift and operating the operation buttons of the elevator, and the load carrying-in / out operation can be prevented from being interrupted. As a result, it is possible to contribute to improving the work efficiency of loading and unloading of the luggage by the worker.

  In addition, even when a problem such as the elevator door closing occurs during the work of loading and unloading luggage, the worker can close the door simply by inputting voice information indicating the operation of opening the door from the microphone 12. The elevator door can be opened again. Therefore, the operation of the elevator can be switched relatively easily and quickly as compared with the prior art in which the operation button of the remote control device has to be operated for voice recognition. As a result, it is possible to prevent the occurrence of an interference accident between the door and the vehicle for loading / unloading the luggage during the work of loading / unloading the luggage. Thereby, safety of the operation of the elevator can be achieved. In other words, the elevator can be operated safely.

  In addition, by using the headset microphone 12 as described above, an operator who inputs voice information through the microphone 12 and operates the elevator operation, in this embodiment, an operator who loads and unloads luggage, and the microphone 12 Can be kept relatively short and constant. As a result, even when an operator inputs sound information from the microphone 12 while driving a vehicle such as a forklift for carrying in and out the luggage, sound emitted from the vehicle itself and ambient noise can be input to the microphone 12. It can be suppressed as much as possible. Therefore, it is possible to prevent the voice information input by the operator from being affected by the sound emitted from the vehicle itself and the surrounding noise and causing a problem such that the voice cannot be recognized or is erroneously recognized.

  Further, according to the present embodiment, the storage unit 28 of the information processing unit 16 is associated with operation information representing one operation of the elevator and an elevator operation word that is a plurality of corresponding speech recognition information. Is remembered. When the information processing unit 16 determines that the voice information input from the microphone 12 matches any one of the plurality of elevator operation words stored in the storage unit 28, the information processing unit 16 sets the matching elevator operation word as a match. Select operation information representing the operation of the associated elevator. The selected operation information is transmitted to the elevator driving unit 3 by the transmitter 18 of the remote operation unit main body 11.

  As described above, since the plurality of elevator operation words corresponding to one operation of the elevator are stored in the storage unit 28 in association with each other, only one elevator operation word is stored for one operation of the elevator. Compared with the case where the information is stored in association with each other, it is possible to increase the voice recognition rate of the voice information input by the worker who loads and unloads the luggage with respect to the elevator.

  In addition, when one elevator operation word is stored in association with one elevator operation, the operator confirms and accurately grasps the elevator operation word corresponding to the elevator operation in advance. It is necessary to keep. On the other hand, in the present invention in which a plurality of elevator operation words are associated with one operation of the elevator and stored in the storage unit 28, the operator confirms and grasps the elevator operation words in advance. There is no need to keep it. In other words, the worker can operate the elevator only by inputting voice information associated with the operation contents of the elevator such as a call operation, an opening operation, and a closing operation. As a result, the operator can operate the elevator with sound that is easy to pronounce, and the convenience of the operator can be improved.

  Therefore, it is possible to save the labor of the operator to confirm and grasp the elevator operation word for operating the elevator in advance, and the convenience of the operator can be improved. In addition, it is possible to smoothly carry out the work of loading and unloading the luggage by the operator, and it is possible to improve the work efficiency of loading and unloading the luggage.

  Further, according to the present embodiment, the storage unit 28 of the information processing unit 16 has the voice recognition operation information representing the start and end operations of the voice recognition and the activation that is one or more corresponding voice recognition information. And a voice recognition end word are stored in association with each other. The information processing unit 16 determines that the voice information input from the microphone 12 matches one of the one or more activation words and the voice recognition end word stored in the storage unit 28. Then, the voice recognition operation associated with the matched activation word or voice recognition end word, specifically, the voice recognition start or end operation is performed.

  Therefore, for example, when the voice information input from the microphone 12 matches the activation word, the information processing unit 16 activates the voice recognition operation associated with the matched activation word, specifically, the voice recognition is activated. When the vehicle is in operation, the voice recognition of the voice information related to the elevator operation including at least the elevator lifting operation and the door opening / closing operation input from the microphone 12 is performed. For example, when the voice information input from the microphone 12 matches the voice recognition end word, the information processing unit 16 ends the voice recognition operation associated with the matched voice recognition end word, specifically, voice recognition. During the operation, the voice information regarding the operation of the elevator input from the microphone 12 is not recognized.

  As a result, the operator can switch the speech recognition start and end operations relatively easily. For example, when there is no need to operate the elevator, the operator himself / herself is terminated by ending the speech recognition in advance. It is possible to prevent voice information represented by an inadvertently uttered voice from being input from the microphone 12, and the input voice information being undesirably recognized by the information processing unit 16. Accordingly, it is possible to prevent the elevator from operating undesirably in response to the elevator operation information corresponding to the voice information input from the microphone 12 undesirably.

  According to the present embodiment, the elevator based on the operation information newly received by the receiver 20 after the operation of the elevator based on the operation information received by the receiver 20 of the elevator driving unit 3 is completed. Are controlled by the elevator control unit 22. Therefore, even when new operation information is received by the receiver 20 during the operation of the elevator based on the operation information first received by the receiver 20, the operation of the elevator based on the operation information received first. The elevator operation based on the new operation information is not started until is completed.

  Thus, for example, when the operation information for closing the elevator door is received during the operation of opening the elevator door, the operation of the elevator suddenly switches to an undesired operation for the operator, and the loading / unloading of the luggage is performed. It is possible to prevent an interference accident between the vehicle for use and the elevator door from occurring. Therefore, safety of the operation of the elevator can be achieved. In other words, the elevator can be operated safely.

  Further, according to the present embodiment, when the elevator control unit 22 operates the elevator in response to the operation information received by the receiver 20, the operation release information indicating that the operation is released, When received by the receiver 20, the operation of the elevator before receiving the operation cancellation information is canceled by the elevator control unit 22. Therefore, even if an operator who loads and unloads luggage with respect to the elevator erroneously inputs voice information of an undesired elevator operation from the microphone 12, for example, the undesired elevator operation is relatively easy and quick. It can be released. As a result, it is possible to improve the efficiency of loading and unloading work compared to a case where the operation cannot be canceled during the operation of the elevator.

  The above-described embodiment is merely an example of the present invention, and the configuration can be changed within the scope of the invention. For example, in the above-described embodiment, the microphone 12 and the information processing unit 16 are electrically connected, but the configuration is not limited thereto. In another embodiment of the present invention, audio information input from the microphone 12 is transmitted to the information processing unit 16 by wireless communication such as Bluetooth (Bluetooth) and wireless LAN (Local Area Network) which are short-range wireless standards. It may be configured as follows.

  The microphone 12, the speaker 13, and the information processing unit 16 may be integrally configured, and thereby the remote operation unit main body 11 can be reduced in size.

  In the above-described embodiment, the lift control device 1 configured to transmit operation information and operation release information from the remote operation unit 2 to the elevator driving unit 3 by infrared communication using IrDA has been described. It is not restricted to such a structure. In another embodiment of the present invention, when the operation information and the operation release information are transmitted from the remote control unit 2 to the elevator driving unit 3, Bluetooth or a wireless LAN may be used.

  Furthermore, in the above-described embodiment, the voice information emitted from the worker and input from the microphone 12 is recognized. However, the present invention is not limited to such a configuration, and other embodiments of the present invention. Then, it may be configured to detect vibration of the throat when the worker utters a voice and recognize that the vibration is related to the operation of the elevator, for example, the opening operation of the door. Thus, the operator can control the elevator operation including at least the elevator up-and-down operation and the door opening and closing operation without sounding words.
