Definitions

• the present invention relates to a method for allocating a user to an elevator system with several elevators, wherein the user issues a destination call and determines at least one elevator for operating the destination call and is notified to the user by means of an acoustic signal indicative of the elevator.
• the invention further relates to such a lift installation.
• a lift system with several elevators wherein in the area of each floor and each elevator a so-called elevator identifier is provided which emits a sound melody characterizing the respective elevator or a group of elevators.
• the sound of the melodies is designed in such a way that a large number of different-sounding melodies are available for the various elevators.
• a destination call delivery unit is provided which has a plurality of switches and a loudspeaker. They are the Different destination floors associated switch marked with different colors.
• the invention has the object of developing a method for allocating a user to an elevator system of the type mentioned in such a way that the allocation of the user by means of the acoustic signal is carried out in a simple manner and with simply constructed components. Furthermore, such an elevator system should be specified for carrying out this method.
• the method according to the invention is based on the finding that, when the determined elevator is announced, the identification of different elevators by the signal tone having a specific frequency is achieved by the signal being interrupted by pauses, lasting for a certain period of time and / or by a combination of these design features is configured.
• the signal can be designed in the manner of a signal code, that is to say by characters of different lengths with optionally interposed pauses.
• the So-called Morse code used which has a simple continuous unmodulated signal as a basis, whereby it comparatively little hardware needed and thus a simply constructed one-frequency encoder can be used as an acoustic signal unit.
• the signals are configured by means of a predetermined signal code, preferably by means of the Morse alphabet code.
• the signals determined for each of the ascertained elevators can be output at a time interval.
• the user outputs the destination call by pressing one or more times at least one switch of a destination call delivery unit.
• a destination call delivery unit may be provided with only one switch in the access area of each floor of the elevator installation, which allows the user to indicate the desired destination floor by correspondingly activating the switch. For example, he presses the switch five times to indicate his destination call for fifth floor transportation.
• the destination call delivery unit may conveniently also comprise an acoustic signal unit so that each actuation of the switch is confirmed by a one-frequency signal tone.
• the user is guided by an acoustic signal to the destination call delivery unit.
• an audible signal in the form of a one-frequency beep or one of a plurality of tones existing melody is first passed to the destination call delivery unit, so that the person can make their destination call.
• an elevator system with several elevators which has at least one destination call delivery unit for delivering a destination call, a destination call control unit for determining an elevator for operating the destination call and at least one acoustic signal unit for emitting an acoustic signal to allocate the user to the determined elevator, all signals identifying the different elevators being formed solely by means of a single one-frequency signal tone, the various signals indicative of the individual elevators being delayed by a predetermined signal duration and / or at least a predetermined signal interruption Users are distinguishable recognizable.
• an elevator system formed in this way makes use of the advantages of the method according to the invention. According to the above statements regarding the method according to the invention, it proves to be advantageous if the signals are configured by means of a predetermined signal code, preferably by means of the Morse alphabet code, to designate various elevators.
• the destination call delivery unit is provided in the anteroom area of the elevator and has at least one switch.
• the destination call delivery unit comprises a plurality of switches, each switch being characterized by a haptic means for designating the switch function, for example the destination floor.
• a telephone keypad or one of the floors corresponding Number of switches are provided, each switch being provided by a corresponding surface design with recognizable by the sense of touch for a visually impaired person name of the floor in the form of braille.
• the signal unit is located in the area of the elevator shaft door, in the area of the elevator car and / or in the anteroom area of the elevator or of the respective floor.
• at least one destination call delivery unit is provided in the access area of each holding station of the elevator installation.
• the destination call delivery unit is provided with a further switch, characterized by visually and haptically recognizable disability symbol.
• the function of this button is that the acoustic signals are only generated if this key is pressed before the destination input in order to prevent the environment from being continuously sounded with signal tones.
• the destination call delivery unit is provided with an RFID reader and the disabled person has a detectable by this reader card or mobile phone.
• the destination and type of disability are stored. The disabled person only has to bring this card close to the reader of the destination call delivery unit to trigger the destination call and automatically get the acoustic guidance.
• An elevator system comprises a plurality of elevators which are movable between a plurality of floors.
• a control unit is provided with a destination call control unit which receives a destination call issued by a user and then determines at least one elevator suitable for operating the destination call.
• a Zielrufabgabetician is provided with a number of floors corresponding number of switches in the area of each vestibule area of the elevator system.
• Each of the switches is emphasized with haptic means in the form of braille to mark a floor.
• each elevator shaft door is assigned an acoustic signal unit.
• This signal unit comprises a one-frequency buzzer arranged to deliver a paused sequence of one-frequency beeps for allocating the user to one of the hoistway doors.
• this user can recognize by means of his sense of touch those switches marked with Braille that correspond to his desired destination floor. After actuation of the corresponding switch, this destination call is transmitted to the destination call control unit.
• the destination call control unit determines a suitable elevator for transporting the user to the desired destination floor and notifies the user of the associated name of the elevator, for example a letter or a number, by means of a correspondingly configured one-frequency signal tone by the audible signal unit of the destination call delivery unit.
• the visually impaired person can orient himself by the signal tone and move in the direction of the assigned elevator shaft door.
• the above-described embodiment relates both to the method according to the invention and to the elevator installation according to the invention and is characterized in particular by the fact that the use of a single-frequency signal generator makes it possible to use a comparatively simply designed acoustic signal unit and, moreover, does not require a great deal of effort designed sound melodies.
