EQUIPMENT AND METHOD FOR TRANSMITTING INFORMATION TO ELEVATOR PASSENGERS

The invention relates to an apparatus for transmitting floor-specific information 5 of a building to elevator passengers according to the preamble of claim 1 and to a method according to the preamble of claim 8, respectively.

Elevators and signaling devices have previously been installed in elevator cars and floor platforms, which provide passengers with information on elevator movements and arrivals, as well as 10 load situations. The information is produced by special display devices, indicator lights connected to call buttons or audible warning devices or combinations thereof. It has also been suggested that general information, such as weather information, be displayed on monito-15s located in the elevator lobby and in the elevator car.

Notice boards have been installed on the ground floor of the building, ie usually on the entrance floor, about the premises of the building and the events to be held in them. The other floors also usually have at least information about the floor number at the elevator level. Separate 20 monitors have been used on both the base floor and other floors. However, known communication devices have various drawbacks. The information provided on the base floor is easily forgotten during the lift journey and floor-level space solutions • · · ··: may not always be in sufficient detail. On the other hand, • · · v * 25 ta placement of information boards at all levels and their »· j .:; constantly updating the data is time consuming and expensive, t ^ installing legal displays on the layers is also expensive and Γ also requires the construction of a separate data transmission line.

The object of the invention is to provide an apparatus for transmitting floor-by-floor information of a building to floor levels which S. '.' laicw <The system can be flexibly and cost-effectively • · · installed on the floor levels of the elevator and allows the information to be easily changed according to the needs.

: *: In order to achieve this, the invention is characterized by the features according to the characterizing part of claim 1.

* *

The method according to the invention is in turn known from the features of claim 8. Other preferred embodiments of the invention are set out in the other claims.

With the apparatus according to the invention, the display unit can be installed flexibly and effortlessly at any point on the 5 floor level. Due to the wireless connection, there is no need for wires, which can be difficult to implement, especially in retrofits. The content and amount of information to be transmitted is dynamically programmable and controllable. If no passengers leave the elevator car on the floor level, floor-10 information is not transmitted. Upon entering the ground floor, guests will receive information on the location of their destination on site. Passengers also avoid stepping out of the elevator on the wrong floor.

Those responsible for the operation of the house can flexibly change the location of the signaling devices and the content of the information. The devices 15 can only be placed on those floors where there is a need for them in each case or to which it is especially desired to transmit information. The content can be programmed to change, for example according to a daily or weekly plan, within the limits allowed by the capacity of the equipment.

In the following, the invention will be described by means of an embodiment thereof with reference to the drawings, in which • · · •: ·. Figure 1 shows a perspective view of a floor platform in which:. is an apparatus according to the invention and I. * - Figure 2 shows the front panel of the signaling device.

»· · * · •, ^ * 25 According to Fig. 1, there are level doors l on the floor deck, next to which • · · '' elevator call buttons and associated indicator lights 2 are arranged. Above the door 1, an elevator travel direction indicator is installed. LEDs 3. Call buttons and LEDs are · connected to the elevator control unit to make calls and • 1 30 to indicate elevator operation, respectively. An infrared transmitter 4, which acts as a signal transmitter and is controlled by the elevator control unit and whose operation is connected to the movements of the elevator car, is installed in connection with the signal light unit mounted above the door. The transmitter 4 transmits the message wirelessly to a receiver and signaling unit 5 mounted on the wall opposite the elevator door. The unit 5 has a receiver for receiving a control signal transmitted by the transmitter 4 and a display device for displaying an image or text and / or a speaker 5 for producing sound. The unit preferably includes a memory implemented on a standard circuit (not shown) in which the information to be transmitted is pre-stored. In this case, only the identification information of the information to be displayed needs to be transmitted by an infrared signal. The signaling unit can be freely placed on the floor. It is equipped with its own power supply, battery or accumulator, which can be charged with power generated by a photocell, for example, or it is connected to the mains.

Figure 2 is a front view of the display unit of the signaling device. The display 7 is formed as a liquid crystal display with the floor number 9 depicted 15 and the locations or objects 10 located on the floor in letters, for example the business names and room numbers as well as the directional arrows 11 for each object. Depending on the ambient conditions, a lighting device is arranged in the display unit.

To enable two-way communication, the display unit also has an infrared transmitter 12 for wireless transmission of information to the elevator control. The actual on-screen display-:. It is preferable to store the information in the display unit. wirelessly, ensuring a two-way .25 connection to store data in memory and its * correctness. The recording can be carried out centrally via elevator control, in which case the information containing the information to be displayed can be stored in the memory via the transmitter 4 and the receiver 6. Alternatively, the message can be stored on 30 separate programming media. Transmitters 4 and 12 are • implemented with LEDs, for example. A photocell 13 is arranged in the display unit for charging batteries (not shown) installed inside the display unit. The size of the display and the amount of • · information to be displayed depends on the current situation and time -;

The primary location of the signaling unit is opposite the elevator door to transmit information to passengers just leaving the elevator, depending on the floor platform architecture, it may also be located at other locations or there may be several signaling units on one level. The display unit is fixed to the wall with screws, stickers, quick-release fasteners arranged on the wall or similar members.

When the elevator car reaches the level under the control of the elevator control unit, the signal transmitter sends a control signal to the receiver in the signaling unit 10. From the receiver, the message is passed to a display missile that reads the message stored in memory and displays it on the screen. At the same time, a loudspeaker or the like can be given through the loudspeaker, which suitably draws the attention of customers exiting the elevator, but is clearly distinguishable from other signals from the 15 elevators. At a suitable time after the arrival of the elevator, the display is switched off, which can be done by the elevator control unit or the display control. Here, the elevator control unit can also utilize the information received from the lobby detector. Depending on the locations on the floor or the events to be organized, the device can be controlled differently at different times of the day.

The invention has been described above by means of an embodiment thereof. However, the presentation is not to be construed as restrictive, but ··: ·. the scope of the patent is free to vary within the limits defined by the following claims.
