FIELD OF THE INVENTION
The present invention relates to a guidance system for an elevator system as defined in the preamble of claim 1 and to a method as defined in the preamble of claim 12.
BACKGROUND OF THE INVENTION
Tall multi-story buildings typically contain numerous elevators, which are arranged to form several elevator groups. Each elevator in the elevator group can take passengers to different floors or floor zones in the building. The operation of the elevators in the elevator groups is controlled by a set of control means receiving the calls entered by the passengers. The calls may be e.g. car calls given from inside an elevator car or landing calls given from different floors. Call arrangements have also been developed wherein the passenger selects the destination floor at the starting floor already before boarding the elevator. For example, U.S. Pat. No. 4,972,926 discloses a solution of this type, wherein both the entry of an elevator landing call and the definition of destination are implemented by pressing a button on a destination call device. Activated by the destination call entered by the passenger, the set of control means determines (allocates) a route that the passenger has to follow in order to reach the destination he/she has selected. In determining the route, the set of control means often utilizes different optimizing methods to optimize the route with respect to desired parameters. The route allocated by the set of control means may be a multistage route, which may comprise several sub-journeys using e.g. elevators, escalators and/or moving walk-ways. In simple routing solutions, the destination call is located on the same floor level, possibly in the same elevator lobby, as is served by the elevator implementing the route. In complex routing solutions, the building has to be provided with numerous display devices, fixedly mounted guide maps and/or other guidance devices to guide the passenger from the destination call device to the destination according to the route. In prior art, various alphanumeric codes are used in the guides of elevator systems to guide the passenger to the right elevator lobby and/or elevator. In traditional elevator systems, the elevator system uses an acoustic signaling device, such as e.g. an arrival gong, placed in the immediate vicinity of each elevator door, generally above it, to announce the arrival of an elevator at the floor in question to the passengers in the elevator lobby.
Prior-art guidance systems involve several problems. Alphanumeric guides often contain codes from which the passenger's route information is difficult to decipher or the codes do not provide sufficiently informative information to passengers. The guidance information may also be too abundant for an individual passenger to be able to find his/her route without difficulty. For the visually handicapped, traveling in elevator systems based on prior-art technology is often almost impossible. The sound signals announcing the arrival of an elevator at the floor are often identical for all elevators serving that floor and are primarily intended to indicate the arrival of each elevator at the floor. As the sound signals on the floor level are identical for different elevators, the elevator passenger can not find the elevator belonging to his/her route on the basis of the sound signals only. Due to insufficient guidance, in large building complexes the passenger often experiences uncertainty in the selection of the correct route and easily strays from the route leading to the destination floor.
OBJECT OF THE INVENTION
The object of the present invention is to overcome the above-mentioned drawbacks and to achieve a completely new type of solution for guiding elevator passengers in an elevator system, in which solution the passenger's needs are taken into account better than before.
An additional object of the invention is to achieve one or more of the following goals:

    
    
        to enable the presentation of guidance information of informative and/or advertising nature in an elevator system.
        to create a solution that will be easy to modify in changing conditions.
        to make it easier for e.g. visually or audially handicapped passengers to move in an elevator system.
        to enable faster traveling in an elevator system.
    
    


The present invention can be applied e.g. in office buildings, hospitals, shopping centers and airports, where people have to reach the destination easily and quickly.

The invention makes it possible to produce guidance information that is clear and easy to recognize at different stages along the route. The invention also makes it easier for visually or audially handicapped persons to move in an elevator system. The swiftness of traveling is increased in many ways, among other things because the same guiding messages are reproduced sufficiently frequently at different stages along the routes and because the passenger can often decide the correct route on the basis of the guidance information only, without using a destination call device to give the destination. The guiding messages are also easy to modify, and various elements of informative or advertising nature can be added to them.



LIST OF FIGURES
In the following, the invention will be described in detail with reference to a few embodiment examples and the attached drawings, wherein
FIG. 1 presents a guidance system according to the invention.



DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagrammatic representation of a guidance system according to the invention, which comprises guiding devices 2a-2d, which are connected via a data transfer link 8 to a set of control means 1 controlling an elevator system. The set of control means 1 comprises means for controlling sub-assemblies of the elevator system, such as e.g. for controlling elevators and/or elevator groups. Moreover, the set of control means 1 comprises a destination call device 9, e.g. a key panel, for receiving passengers' destination calls, and means for allocating the said destination calls as route data.
The guiding devices 2a-2d contain a control unit 3 and a number of sound reproduction means 4 for the reproduction of guiding sounds. In the case illustrated in FIG. 1, the guiding devices 2a-2d additionally contain a display means 5 for the reproduction of guiding images. The control unit 3 contains a memory means for storing at least one guiding message into the guiding device 2. The guiding messages are stored into the memory means of the control unit 3 in conjunction with the commissioning of the elevator system, in conjunction with maintenance of the elevator system and/or during operation of the elevator system. The guiding messages can be stored into the guiding devices 2 over a data transfer connection, e.g. over data transfer link 8. The guiding messages are stored on the memory means of the control unit 3 as separate sound or image records and/or as paired audiovisual records containing both sound and image. When reproducing the guiding messages, the control unit 3 generates a sound signal 6 corresponding to the guiding message records stored on the memory means to produce guiding sounds on the sound reproduction means 4, and/or correspondingly, an image signal 7 to display guiding images on the display means 5. In simple guidance solutions where the guiding image is fairly unchangeable, the guiding image used may also be a photograph or a similar graphic image, icon or symbol, in which case no record of the guiding image needs to be stored on the memory means of the control unit 3 and likewise no image signal 7 has to be generated. Each guiding message is reproduced on one or more guiding devices in a continuous reproduction process, from time to time and/or as controlled by an external stimulus. The external stimulus may be e.g. an external signal 10 connected to the guiding device and/or a data message transferred to the guiding device via a data transfer connection, e.g. data transfer link 8. If the guiding message comprises both a guiding sound and a guiding image, the guiding sound and image in question can also be reproduced on the guiding device independently of each other, in other words, the guiding sound alone or the guiding image alone is reproduced, or both the guiding sound and the guiding image are reproduced simultaneously. In FIG. 1, the terminal device 11 represents a passenger identification device, e.g. a reader working on a radio frequency, for detecting a sensor carried by the passenger and generating an external signal 10 based on the identification. The identification device enables individual guidance information intended for the passenger to be presented in the guidance system. For example, handicapped passengers can be guided to a route that will serve their needs better than some other route alternatives with the same destination.
The guiding devices can be installed in the elevator system in the immediate vicinity of connecting galleries, escalators and/or elevators, e.g. on the floor levels above the elevator doors and/or in conjunction with the elevator cars. As shown in FIG. 1, one of the guiding devices is mounted in conjunction with the destination call device 9 (guiding device 2a in FIG. 1).
In the elevator system according to FIG. 1, the passenger gives his/her destination call data by using a destination call device 9. The passenger's destination call data is transmitted via a data transfer connection 12 to the set of control means 1, where the passenger's destination call data is allocated as the passenger's route data, whereupon the set of control means 1 sends to the guiding device 2a a command in the form of a data message to reproduce the guiding message corresponding to the route in question. On the basis of the aforesaid reproduction command, the guiding device 2a reproduces the guiding message corresponding to the route allocated to the passenger, who can reach his/her destination in the elevator system by following the said guiding message. In cases where the passenger already knows or can easily infer the content of the guiding message that will guide the passenger to the destination, the passenger need not necessarily give his/her destination call data via the destination call device. Such cases include e.g. situations where the passenger regularly visits the building in question or the guiding sound corresponding to the passenger's route can be easily guessed e.g. on the basis of the destination of the route. When the passenger is familiar with the guiding message that he/she will have to follow, he/she can start the journey and move e.g. into the entrance lobby to await an elevator belonging to his/her route. When the elevator arrives at the entrance lobby, the set of control means sends to the guiding device associated with that elevator a command to reproduce the guiding message corresponding to the route implemented by the elevator, whereupon the guiding message corresponding to the route is reproduced on the guiding device, guiding the passenger to the right elevator. It is advantageous to add to the guiding message a guiding image as well, which is reproduced beforehand on the guiding device associated with the elevator implementing the route to give advance information regarding the arrival of the elevator at the entrance lobby. Thus, the passenger can move closer to the right elevator in time to await the arrival of the elevator. At later stages of the route, the same guiding message is repeated to the passenger via the guiding devices located along the route, guiding him/her to the desired destination.
According to the invention, the guiding sounds used are sounds that can be easily distinguished from each other. When the guiding message comprises both a guiding sound and a guiding image, the guiding sound and guiding image are so selected that an associative connection exists between the guiding image and the guiding sound corresponding to it. Table 1 presents a few examples of pairs of guiding sound and guiding image with an associative connection between them which may be used in the guiding messages.
