Definitions

  • the invention relates to a control device for an elevator, an elevator with a such a control device and a corresponding control method.
  • control devices for these known elevators are relatively easy to use. However, there are situations in which it is not easy for users to operate. For example, blind users must first find the right button based on the label Find. In particular, however, the user must always know in advance which floor your desired destination - for example, a conversation partner or a functional room - located.
  • a console has means for audio recording.
  • every terminal in the elevator is understood. Usually include such devices acoustic and / or graphic display elements and input options (Keys, key switch etc.).
  • such Console also be very simple, in the simplest case it can only be Include audio recording media.
  • Control information is entered in such a console, that is, inputs of the Users who are used to control the elevator. While this is done conventionally If the floor button is pressed, a user can use the elevator control by voice command.
  • a means for audio recording is available for this, for example a microphone, preferably with a device for digitization and signal coding.
  • the term “Recording” means all means by which audio signals are received and can be processed. On the one hand, this includes “recording” in the sense that a block is first recorded and stored, which is then processed. On the other hand, this also means online signal processing of the converted audio signals includes that does not need to be saved.
  • the recording means are connected to a speech analysis unit. So he can User control information in the form of a voice command or spoken Enter question.
  • the recorded (and possibly digitized or encoded) audio signal is analyzed by the speech analysis unit, i.e. the speech analysis unit tries the spoken ones Recognizing words.
  • speech recognition systems are known per se. Of course, a speaker-independent recognition system is preferred here.
  • the speech analysis unit provides a representation of the recognized speech command or the recognized phrase.
  • This information is stored in a control unit processed in such a way that the elevator is controlled in accordance with the entered control information becomes.
  • the speech analysis unit delivers the analysis result the words "second floor" in the audio recording.
  • the control unit recognizes that the user has given the command to move the elevator to the second floor.
  • the control unit controls the Auryak accordingly, so that it goes to the second floor moves.
  • the distinction between a speech analysis unit and a control unit is purely functional.
  • the implementation can be separate devices but also two modules one Device or even a single program that runs on a computer and together fulfills both functions.
  • a control center is outside the elevator intended.
  • Such a control center that works with the console through transmission means, for example a wired bus system or wireless transmission means, e.g. Infrared or radio, is usually connected as an electronic control circuit or be designed as a computer.
  • the speech analysis unit on the console inside of the elevator is arranged, wherein the speech analysis unit directly to the recording means is connected and the voice recording is analyzed immediately. It is the same possible that the speech analysis unit is arranged at a fixed location outside the elevator is. In this case, the audio recording becomes from the console to the speech analysis unit transmitted, preferably in digitized, coded form, the ones already described Transmission means could be used.
  • Such a database is preferably kept centrally for the entire building. That's how it is
  • database can be easily maintained centrally (e.g. the name of a new employee can be entered).
  • control systems for multiple elevators access a database centrally.
  • the control unit also uses one Database, preferably to the same database as the speech analysis unit.
  • this Database is for every location description (control information, recognized voice command) the control command to be triggered is saved.
  • the control unit reads the stored control commands in audio representation and send it to the elevator.
  • this includes control information processed and recognized voice commands not only direct location information (e.g. "second floor”), but indirect location descriptions are also understood.
  • "Indirect” descriptions of locations are used to refer to descriptions that are assigned to a location description via a link. For example, a Voice command "to Mr. Meier” recognized. By evaluating a previously created saved link, it is found that Mr. Meier has a room on the third Stick. This is "to Mr. Meier” an indirect location description for the third Stock, so that the corresponding control commands are triggered.
  • links are advantageously stored in a database where they are not are stored permanently, but can be changed.
  • this includes longer-term Changes (e.g. Mr. Meier moves from the third to the fifth floor).
  • short-term changes for example, can be updated daily in the database can be entered.
  • Constant updates are particularly advantageous for indirect location descriptions. If the database dynamically keeps this information up to date, you can also consider, for example, situations in which the assignments are more indirect Change location descriptions during the day. So the database can be updated , for example when Mr. Meier (who usually works on the second floor) is in a meeting is in the meeting room (third floor). The indirect location description "Meier" then shows this permanent instead of the second on the third floor Updates are particularly interesting in buildings where the people working there People are dynamically assigned to one of the offices each day.
  • a control system according to the invention which reacts to natural language inputs can of course be used in parallel to previous systems with key operation. It is preferred that the key operation has priority and so (especially wrong understood) voice inputs can be overwritten.
  • a control device 10 for an elevator is shown schematically.
  • the Elevator car 12 travels in an elevator shaft 14, being driven by a drive device 16 (shown here symbolically as a winch).
  • a console 18 is arranged inside the elevator car 12.
  • the building is equipped with a house bus 20. This is only symbolic here shown, in addition to common wired bus systems, it can also be a wireless transmission technology, for example Bluetooth.
  • the console 18 is on this
  • the house bus is connected, as is the drive device 16 also a control center 22 connected, which has access to a database 24.
  • at the control center 22 is a central house computer, which in addition to the elevator control controls other units in the building.
  • the components are connected to each other in the following way:
  • the console 18 comprises a voice recording unit (not shown) consisting of a microphone, an A / D converter for digitizing the audio data and one Encoder module for coding the digital data in a common audio format, e.g. PCM.
  • the console 18 is connected to a bus interface 28 via a data line 26. Via the data line 26 and the bus interface 28, the recorded and coded audio data to the house bus 20. The audio data is over the Transfer house bus to the control center 22.
  • the control center 22 is shown in detail in FIG. It comprises a speech analysis unit 30 and a control unit 32.
  • the audio data A are read from the house bus 20 and analyzed in the speech analysis unit 30.
  • This is an electronic one Circuit or a computer with a corresponding analysis program, algorithms known to the person skilled in the art for speaker-independent speech recognition be used.
  • the speech analysis unit 30 accesses the database 24.
  • the database 24 is stored the vocabulary that the speech analysis unit 30 is to recognize. this includes direct location information such as "first floor”, relative location information “one floor up” and indirect location descriptions (e.g. "to the conference room”).
  • the result of the speech recognition is used by the speech analysis unit in the form of digital Data E (tokens, which are assigned words recognized via the database) to the Control unit 32 passed on.
  • digital Data E tokens, which are assigned words recognized via the database
  • the control unit 32 decides which control command C to be sent out. Here, it also accesses the database 24. In the Database 24 are the possible direct or indirect location descriptions each assigned control commands C stored. After reviewing the analysis data E the control unit 32 calls these control commands C and transmits them the house bus 20 to the drive unit 16.
  • control center 22 is a central computer. This comprises the speech analysis unit 30 and the control unit 32 as software modules.
  • the voice command is recorded, digitized within the console 18 and coded and then via the data line 26 and the bus interface 28 via the house bus 20 sent to the control center 22.
  • the corresponding Audio data read out and a speech analysis by the speech analysis device 30 subjected.
  • This recognizes on the basis of the data stored in the database 24 Vocabulary the words “zu”, “Herrn”, “Meier” and “bitte”, and sends them in digital Form (for example tokens) as signal E to the control unit 32.
  • the control unit 32 applies a simple syntactic analysis to the recognized phrase and removes it recognized as superfluous "to” and the addition "please”.
  • this is also capable of dialogue.
  • the console Integrated speech system It is either a synthetic system Speech output, the words to be output as text from a dialogue unit be transmitted. Or it is a D / A converter with connected Loudspeaker, so that words transmitted as audio data are output by the dialogue unit become.
  • the dialog unit is also arranged in the control center 22. It evaluates the recognized Voice commands from If these are not or not clearly assignable, ask to the user for this purpose, it controls the voice output system via the house bus 20 in the console 18 so that it addresses the query to the user. Only when that Command is clearly assigned, it is sent to the control unit for the corresponding Control passed on.
  • the dialog unit can also be accessed with a correspondingly constantly updated Database take on more complex tasks of the organization. So she can determine that, for example, Mr. Müller has his office on the second floor, but is currently in a meeting is on the third floor. It can communicate this to the user, various reactions to choose and arrange the appropriate, for example, if the If users want to wait in Mr. Müller's office, notify him.
  • the console can also use other acoustic or graphic means Display elements include.
  • Such display elements in the elevator can also be used are used to provide more information about the destination. For example further information when exiting the elevator, e.g. Direction information "the Space is given on the right at the end of the aisle ".
  • a printer can also be used directions are printed out that the user takes with them.
  • the voice interface can automatically when a person enters the elevator to be activated. This can be done with the help of the light barrier or by changing the weight be determined.
  • the user can enter his voice command prompted by an appropriate display (voice message or graphic display) become.
  • the audio functions of the console can also be used to establish a communication connection be used in an elevator malfunction.
  • corresponding Inquiries or calls for help from the user regarding the vocabulary of speech recognition 30 belong, so that when these commands are recognized, an emergency signal is automatically triggered becomes.
