ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a communication system having at least one mobile communication device.
Communication systems of this generic type that can move their location are known. They have at least one mobile communication device, by means of which an action of further devices communicating with the communication device can be tripped. For instance via a remote controller of the communication device, various pieces of equipment and/or devices can be actuated within a usage area. Typical usage areas are for instance a building with multiple spaces, where different pieces of equipment can be actuated inside the spaces by means of the communication device. Since when remote controllers are used the radio waves have the property of penetrating both the boundary walls of the individual spaces and objects, the communication device necessarily has to be designed in such a way as to enable operating only one particular piece of equipment, without tripping other devices in other spaces that are also actuatable with the communication device. To that end, it is known to provide the communication device with a corresponding number of actuating means, so that each possible control function within the operational range can be executed separately, or so that some control functions can be projected onto a combination of actuating means, or a chronological succession of actuating means.
SUMMARY OF THE INVENTION
The communication system of the invention that can be moved from place to place, offers the advantage that in a simple way, a spatially dependent multiple use of actuating means of the communication device is possible. Because within one usage area of the at least one communication device, position marks are assigned to defined regions which position marks, upon entry of the communication device into the defined region of the communication device impart the actual position, an automatic switchover of the communication device, and in particular the setting of the at least one actuating means, can be switched over to tripping of an action of a device located in the current defined region. Thus by means of one actuating means, many different devices can be actuated; this substantially improves the ease of use of the communication device.
In a preferred feature of the invention, the position marks generate electromagnetic waves, which are received by the piece of communication equipment; position marks belonging to one usage area broadcast different electromagnetic waves per defined region, so that an unambiguous association with a defined region is possible. By way of the electromagnetic waves received from the communication device, an association with the defined region can be made, and internally in the communication device a switchover of the setting of the actuating means can be done.
In a further preferred feature of the invention, it is provided that the position marks are activatable by the communication device. As a result, it is highly advantageously attained that the position marks issue a position signal to the communication device only whenever the communication device enters the defined region associated with the active position marks. Thus all the position marks within the usage area are in readiness and are activated only whenever the communication device enters their region.
