The present disclosure relates to an elevator system, and more particularly, to a visual communication system of the elevator system.
Traditional elevators may be found in any structure having multiple levels or floors. Typically, and while in motion, the elevator car of an elevator confines the passengers within the elevator car space. When a floor destination is reached, doors of the elevator system will open allowing passengers to exit the elevator car. Reliable operation of an elevator may be reliant upon the surrounding structure which supports the elevator and/or a reliable power source that supplies electrical power for elevator operation (as two, non-limiting, examples). Failure of either, or for any variety of other reasons, may cause an unusual event that may confine the passenger to the elevator car for an undesired and extended period of time. Improved means to communicate with the passengers for at least the period of the unusual event, or confinement, is desirable.
A visual communication system for an elevator car of an elevator system according to one, non-limiting, embodiment includes a voice recognition module configured to recognize a first voice communication originating from a source remotely located from the elevator car, and generate a text message; and a text display disposed in the elevator car and configured to visually display the text message indicative of the first voice communication.

In the alternative or additionally thereto, in the foregoing embodiment the method includes auto dialing a communication link between the source and the passenger upon occurrence of the unusual event.
The foregoing features and elements may be combined in various combinations without exclusivity, unless expressly indicated otherwise. These features and elements as well as the operation thereof will become more apparent in light of the following description and the accompanying drawings. However, it should be understood that the following description and drawings are intended to be exemplary in nature and non-limiting.
Various features will become apparent to those skilled in the art from the following detailed description of the disclosed non-limiting embodiments. The drawings that accompany the detailed description can be briefly described as follows:
Referring to
The visual communication system 28 may include the source 30, a voice communication module 32, a voice recognition module 34, a visual display or screen 36, a microphone 38 and a speaker 40. The display 36, the microphone 38 and the speaker 40 are located in the elevator car 22 for interaction by the passenger 24. The voice communication module 32 and the voice recognition module 34 may be supported by the elevator car 22 (i.e., travels with the elevator car). In case of an unusual event such as, for example, a power outage, the system 28 may include a back-up power supply or source 42 such as, for example, a battery.
Because the source 30 is located remotely from the elevator car 22 and may be located remotely from the building 26, a line or path 44 may provide two-way communication between the source 30 and the passenger 24 via at least the voice communication module 32. The path 44 may include wired and/or wireless paths. Non-limiting examples of wired paths 44 may include paths that pass through the internet, local area network equipment, and other networks. Non-limiting examples of wireless paths may include cellular telephone network paths, local area network paths, and others.
The source 30 may include an attendant or first responder who is alerted of what may be an unusual event associated with the elevator system 20. An example of an unusual event may be a power outage in the building 26. An alert of the event to the source 30 may occur in any variety of ways or communication channels. Such channels may be part of the visual communication system 28, or separate therefrom. Examples of an alert means may be through the OTISLINE® system, and/or the passenger 24 may initiate the alert by pressing an emergency button (not shown) in the elevator car 22, or by some other actuation. Upon an alert, an auto dialer 46 of the voice communication module 32 may connect communications via path 44 and between the source 30 and the voice communication module 32.
The voice recognition module 34 may be any variety of modules known in the art, and may include a computer processor for converting a voice communication signal (see arrow 48) received from the voice communication module 32 into a text message signal 50 transmitted to the display 36. The display 36 may be a led, plasma or other type of screen capable of visually displaying a text message 52 indicative of the text message signal 50, and may further be interactive and/or a touch screen for interaction by the passenger 24. An interactive display 36 capable of initiating a response to the source 30 may be useful for the hearing impaired and/or those passengers with speech impediments.
The speaker 40 may be a redundant means of audibly broadcasting the first voice communication signal 48 as an audible voice message 54. The audible voice message 54 may be particularly useful for sight impaired passengers 24 not capable of reading the text message 52. Alternatively, headphones as an example of a speaker 40 may be useful for the hearing impaired passengers 24 for receiving the first voice communication signal 48.
The voice communication module 32, the voice recognition module 34, the display 36, the microphone 38 and the speaker 40 may be packaged together as one unit (e.g. supported by a common housing). Alternatively various components may be separate from one-another with a plurality of communication paths and power lines routed there between.
Referring to
When the passenger 24 hears the voice message 54 and/or reads the associated text message 52, as step 116, the passenger 24 may audibly respond to either message 52, 54 by speaking into the microphone 38 which transmits a response signal 58 through the voice communication module 32, through the path 44 and to the source 30. As yet another step 118 (and one that may occur at any time), the normal power source of the elevator system and thus the voice communication system 28 may fail due to the unusual event. In such a case, the back-up power source (e.g. battery) may provide electrical power to the communication module 32, the recognition module 34 and the display 36.
While the present disclosure is described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the present disclosure. In addition, various modifications may be applied to adapt the teachings of the present disclosure to particular situations, applications, and/or materials, without departing from the essential scope thereof. The present disclosure is thus not limited to the particular examples disclosed herein, but includes all embodiments falling within the scope of the appended claims.
