further information For this purpose, for example, are available on the Internet at http://www.ai.wu-wien.ac.at, written by M. Schwarz in connection with a seminar on information management under the direction of Prof. Dr. Wolfgang H. Janko.

In this publication are also called different location systems that are used for extraction position data and are already available on the market.

The The best known of these is the Global Positioning System (GPS), the the generic term for satellite-based Location systems forms and essentially 24 satellites and associated base stations includes. The positions of targeted objects are determined by triangulation certainly.

On another system, also mentioned at the specified location, which originally was the Localization of employees of an organization in buildings for The goal was "Active Badge ". Everyone wears Person a badge, which receives an identification code at regular intervals via infrared sends out, which is recorded by a receiver network and processed into location information in a central system becomes.

An "Active System called Bat is an advancement based on ultrasound and triangulation based and enables precise 3D positioning in the centimeter range, so that too the orientation of an object in the room can be determined. Unfortunately, this becomes a lattice-shaped Network of sensors required which have to be about 1.2 m apart, which means this system is very complex and expensive.

As Another location system is only the location with normal GSM cell phones mentioned, being for locating objects, the transmitting and receiving systems of the mobile network be used. The position data is determined in usually by measuring the transit times and determining the transit time difference of signals. However, the accuracy of the position data that can be determined in this way depends depends essentially on how close the transmitting and receiving systems of the Mobile operator are set up. So have in well cared for cities these are a distance of 200 m from each other, while in rural areas too much larger distances up to 20 km usual are so these The way of location, especially in the latter case, is very imprecise Delivers results.

to Application of these technologies or systems requires software and hardware components, such as mobile devices in the form of laptops, pocket computers or mobile phones with which it to a user etc. possible is to enter, process and retrieve data or initiate certain actions by entering commands. These devices then also communicate with the location systems so that it is possible based on the determined position data on the basis of route plans Selected users Objects.

adversely in the known control and communication systems, however, is that of Users to select Objects behave passively and therefore only with limited Function can be integrated into the way guidance system, what both finding these objects and transmitting them of information relating to these objects.

There is also a major disadvantage in that only location systems are used that deliver either global position data or local position data, so that either the suitability for user guidance outside of buildings (based on global position data determination) or inside of buildings (based on local position data determination) is given.

In order to connected there is currently no possibility of parallel operation of global and local positioning systems. As a result, the possibility while operation of the global positioning system discrete local Show information on the reduction of global management information (e.g. when walking through a city, such information as "Caution Level "," underpass "for blind People, but also information about a building for non-disabled passers-by).

On Another disadvantage of existing local positioning systems in that this on buildings are bound because they require a high level of technical effort. A Location and active guidance outside of buildings in places where a tour is not possible or is only insufficiently possible using a global system, e.g. in the forest or generally under trees, in narrow streets, underpasses among other things, is not possible or only theoretically possible with these systems.

The the technical status is still insufficient in that regard, than merely selected (Authorized) people can be located in local systems and managed if necessary can and usually only in a building or building complex. Consequently it is impossible, that a any person is localized and guided in any number of objects.

Of starting from this prior art, the object of the invention based on a control and communication system of the aforementioned Kind in such a way that the finding of fixed as well as portable Objects possible that are both inside and outside of buildings can, and also the output of information related to these objects or their Affect the environment, guaranteed to a non-mobile user is.

According to the invention, that the objects Object identification units are assigned, on which identification codes for the associated object are stored, and that the communication facilities for the purpose of data exchange with both the information carriers, the Position transmitters as well as with the object identification units in Connect.

In order to it is ensured that in the communication device information is available at which positions within the coordinate system determined by the assigned object identification unit identifiable objects and, in connection with the route plans, via which Connection paths of the users of the communication device to one selected by him Object arrived. It is both possible to lead to objects that are firmly positioned in the coordinate system as well as objects, the portable are.

there can the object identification units directly with or with several of the objects are connected or in the vicinity of one or more of the objects are located.

As Position transmitters are both global position transmitters and local ones Position encoder provided.

As Local position indicators are used in the context of this invention not just position sensors for location within buildings or rooms understood, but also position transmitter for locating objects outside of buildings as well as outside and inside rooms, where, alternatively, global position data is also available. This makes alternate or parallel operation global and local positioning systems with automatic or manual switching possible.

is the communication device is outside, for example an area in which global position signals are available, can position data from a local position transmitter, the communication device is located on the other hand, within such an area in which global position signals available are the position data from a global and possibly local Position sensor detected and processed.

Besides, is the data exchange can be switched between global Position transmitter and the communication device or a local Position transmitter and the communication device. Alternative is however, parallel operation of global and local position transmitters is also possible.

Satellite positioning systems such as GPS, GLONASS (GL Obal'naya Navigatsioannaya Sputnikovaya Sistema), GALILEO, or cellular networks come into consideration as global position transmitters. Auto-identification systems such as RFID (radio frequency identification), barcode and the like can be used as local position transmitters sentence come.

According to the Switching of data exchange with a global or local position encoder specified automatically or manually, whereby the automatic switchover is initiated dependent on from the current position of the communication device or from of availability a global or a local position encoder, and manual Switching initiated is activated by the user entering control commands from the Communication facility.

Thereby Is it possible, partly the user to whom the communication device is assigned on the basis of a global position encoder, partly on the basis of to maintain position data obtained from a local position transmitter.

It can e.g. be provided that the Switching from a global position encoder to a focal one Position transmitter takes place when passing the entrance area of a building, by declining the intensity of one from a global Position transmitter emitted identification signal below a predetermined A switching command is generated.

alternative it is conceivable to switch over when passing through the entrance area of a building by causing a proximity switch installed in the entrance area is a toggle command is generated. In both cases ensures that within as well as outside the building Position data available stand after linking with a route plan in the communication facility enable the user to the object selected by him.

Farther there is an option that during the Operation of the global control system discrete detailed information controlled by a parallel active local system (precisely) (e.g. "Caution Steps "," underpass "," traffic lights "etc.).

there come inside buildings advantageous transponder-based Location systems for use in which the object identification units are designed as active or passive transponders that both only have readable as well as readable and writable properties can.

As Objects come into consideration: plants, animals, people; Goods and Service provision; geodetic measuring points; Building, Components of buildings; Exhibits, works of art, cultural assets; stationary technical facilities, such as machines or systems; mobile technical Facilities such as vehicles or airplanes; Fixed marks attached to fixed Positions are arranged, and so on.

As Information carrier, which especially for storing the properties of the objects relevant information can only be readable as well also readable and writable Data storage can be provided.

• - A computing module that serves to link the data exchanged between the modules of the communication device and the object identification units, the information carriers and the position transmitters.

It is within the scope of the invention that, depending on the equipment, the communication device is equipped either permanently or temporarily with one or more route plans in the form of loadable software. It is envisaged that the routes in each case related to the current location of the communication device in a region or within a building plans are loaded into the communication device by data transfer and optionally deleted when you leave the building (saving the storage capacity).

is the user with the communication device outdoors a city, the route plan corresponds, for example, to the street map this town; is the user with the communication device inside a building, corresponds to the route plan, for example, the room plan of the building or, if it is a supermarket, the route plan between the Goods shelves.

in the It is also within the scope of the invention that the communication device Access rights are assigned, the scope of which is determined by the user of the communication device dependent is.

Especially The communication device can advantageously be provided with means for preferably acoustically or visually perceptible information output be equipped. So is especially for visually impaired users Voice input and voice output provided.

The Exchange of data between the individual components of the control and Communication system can be both wired and non-wired Communication channels take place.

The invention will be explained in more detail below using exemplary embodiments. In the associated 1 the basic principle of the control and communication system according to the invention is shown, from which the general interaction of the individual components of the control and communication system can be seen as follows.

A number of objects 1.1 to 1.n (n as an integer) are object identification units 2.1 to 2.n assigned. In the object identification identification units 2.1 to 2.n At least identification codes are stored, which are the assigned object 1.1 to 1.n concern, characterize and make it identifiable.

The object identification units 2.1 to 2.n can be designed, for example, as transponders, which record the identification code in a data memory and emit this code in the form of a corresponding signal when activated by an electromagnetic field, in the range of which they are located.

To 1 are still several information carriers 3.1 to 3.k (k as an integer), on which information is stored that relates in particular to the properties of the objects. The information is assigned to the respective object code and is given as a data stream when requesting and calling this object code, taking into account an access authorization if necessary.

A communication device 4 that is assigned to a user who is just like the objects 1.1 to 1.n located in a spatial coordinate system, has an identification module 4.1 on that for reading the identification codes from the object identification units 2.1 to 2.n serves. Have the object identification units 2.1 to 2.n A writing device, which can also be written to, can also be used to write the identification codes or further information into this memory from the communication device 4 be provided from.

The communication device 4 is still with an information retrieval and transmission module 4.3 equipped to exchange data with the information carriers 3.1 to 3.n serves.

So it is the user of the communication device 4 with appropriate access authorization using the information retrieval and transmission module 4.3 possible to one or more of the objects 1.1 to 1.n , which are determined by the assigned identification code, information from the information carriers 3.1 to 3.k retrieve.

there are in addition to information about the properties of the objects, such as coordinates, age, lifespan, Expiration date, scope, dimensions, weight, volume, material properties etc. for example also information about the number of available objects of the same type can be called up. It is also conceivable to find route plans this and other objects.

Furthermore, the communication device 4 with a position data acquisition module 4.2.1 equipped for communication with a global position encoder 5.1 is provided. The global position encoder can 5.1 preferably as a satellite-based positioning system, such as GPS, and via a number of positioning satellites 5.1.1 to 5.1.i feature.

Because of the data exchange between the communication device 4 and the global position encoder 5.i it is possible to position data of the objects 1.1 to 1.n to determine and also to the communication device 4 belonging computing module 4.4 to provide. Darüberhin from it is also possible to acquire the position data that the communication device 4 or the user of the communication device 4 concern so that the computing module 4.4 this position data is also made available.

Using the computing module 4.4 will be the location data that the objects 1.1 to 1.n concern and the position data representing the position of the communication device 4 or relate to the position of the user, linked to a route plan by data exchange from one of the information carriers 3.1 to 3.k into the computing module 4.4 will question. This route plan can relate to the region in which selected objects are available 1.1 to 1.n are located and in which the user with the communication device 4 located.

In a further advantageous embodiment, the communication device has 4 still via a position data acquisition module 4.2.2 which is used for data exchange with a local position encoder 5.2 is trained. The local position transmitter 5.2 For example, provides location data that is related to locations within a limited area where global location data is not or only insufficiently available, or to locations within a building. This makes it possible for the computing module 4.4 by means of the position data acquisition module 4.2.2 Position data of these locations and the position data of the user or the communication device 4 to make available and to link with a corresponding route plan, which, as already shown, from one of the information carriers 3.1 to 3.k into the communication facility 4 is taken over temporarily or permanently or to display discrete information on local specifics in the case of parallel operation with the global system.

In the event that the object identification units 2.1 to 2.n and the individual local position transmitters 5.2.1 to 5.2.j are designed as transponders of the same type, only one common module is sufficient for identification and position data acquisition ( 4.1 = 4.2.2 ). The differentiation between the signals for object identification and the position signals then takes place within the stored databases on the basis of the specific code.

The linking of the respective position data with the route plan serves to provide an optimal connection path from the communication device 4 to a selected one of the objects 1.1 to 1.n to determine, to inform the user and thus to show him the way to the selected object.

It goes without saying the reverse is also possible namely the selected one Object, if this is possible with means of transportation and orientation is equipped to show the way to the user.

According to the invention, it is further provided that the position data can optionally be taken over from the global position transmitter 5.1 or the local position transmitter 5.2 or simultaneously both from the global position transmitter 5.1 as well as the local position transmitter 5.2 can be done.

Switching the transfer of position data from the global position encoder 5.1 or the local position transmitter 5.2 is either by manually in the communication facility 4 control command to be entered or by an externally generated and to the communication device 4 transmitted control command causes. The latter is done, for example, by lowering the received signal from the global position transmitter 5.1 below a predefined setpoint, for example when entering a building, is used to generate a switchover command, or by generating a switchover command when passing through the entrance area of a building by a proximity switch installed in this input area, or by displaying local information in parallel operation.

The possibilities shown here, Generating such a toggle command is exemplary Information, every other possibility is included in the scope of the invention.

following The invention is now to be illustrated by specific examples are explained in more detail.

In In a first embodiment, the objects are machines, Equipment, vehicles or the like technical facilities provided to maintain at more or less regular intervals and are waiting. These objects are called object identification units Assigned transponder.

On a PC used as an information carrier in the maintenance center of a technical company are, for example, the date of the last scheduled maintenance, the last unscheduled repair, the scheduled maintenance interval, information on the wear parts that are to be replaced during scheduled maintenance, manufacturers, supply options and stock levels the wear parts, their intended and actual lifespan, possibly hazardous substances, etc. are saved. This information can be called up by a maintenance technician, to whom a communication device is assigned, via line-free data transfer from the information carrier and visually perceptible by means of the communication device on the display.

As well can from the information carrier a route plan can be downloaded, for example, on moves into a machine shop and the route plan within the machine shop equivalent. From a local position transmitter that is used for detection of coordinates within the machine hall the position data of a selected one Machine or system related and in the communication facility linked to the route plan, so that it the maintenance technician, e.g. is also possible in the event of an accident, the location of the machine or related media, To quickly find lines etc. and initiate the measure there, which must be carried out according to the maintenance schedule or other instructions.

is the communication device is also equipped with the possibility of communication via mobile radio, receives the maintenance technician receives such instructions from a dispatcher who is in the maintenance center and can, without going to the maintenance center to return to have to, to the next Machine can be ordered. It will then be the easy way Data for the machine just serviced on the communication device deleted and therefor the data including directions loaded onto the communication device that affects the machine, the next one according to the instruction to repair or maintain.

In In a special case, the maintenance technician has access rights assigned by entering a personal code can activate in the communication device, thereby preventing will that unauthorized or untrained people have access to those in the maintenance center have saved information (e.g. call up plans, ordering software activate, explore suppliers etc.).

In a second concrete design example are as objects geodetic Measuring points provided, which, for example, in open terrain as markings are appropriate and the basis for surveying services of different kinds.

The Measurement points are again object identification units assigned in the form of transponders, making it a surveyor is possible on site by means of a communication device, by activating the transponder of a measurement point identification code stored on the transponder or others Retrieve information, connect to an information carrier, on which data is stored, this and other measurement points affect. So it is possible dependent on retrieve information from the respective identification code such as Property owners, cadastral extracts, possibly nearby stored hazardous substances, nearby power lines etc.

Under Inclusion of a location system, in this case based on a global position transmitter, conversely a measurement point can be found quickly be by linking the position data is carried out with a site plan available in the information carrier, and it can about that In addition, control measurements for possible changes in the location of the measurement points in terrain carried out become. Deviations from the position are then reported to the information carrier in the Headquarters transmitted, whereupon evaluations and conclusions are made can be pulled.

Also in this context different users of the communication device personal Access rights are assigned to the information available in the control center, such as the fire brigade for fire fighting or civil engineering companies for orientation in line construction.

there may provide the information to the respective user be charged for by the useful life or the amount of transferred Data used in cost accounting.

On third design example relates to facilities for general, non-disabled users and in a special application for the blind and Visually impaired and is used to help such people, e.g. without too Accompanying person, within a defined space, for example a city, a department store, an authority, etc. to give and to provide information that the current Location of the person concerned and their immediate or other Environment.

So it is provided, for example, that the buildings within a city, the shelves within a department store or the areas of responsibility within an authority Transponders are assigned as object identification units, and e.g. the blind or partially sighted, who in this case is a user assigned communication device, based on the information provided by a Object identification unit retrieved identification codes information receives from a central data store, for example at a any place of the City, department store or authority is positioned.

In in this case, the communication device with a voice output provided to the user as needed based on the communication device loaded route planner and its link with your own position data and the position data of, for example, a public building in the city, a telephone booth, a bus stop, a traffic light-regulated one Intersection, a doctor's address, etc. allows acoustic guidance.

The In this case, the communication device is again a handheld or Pocket PC, and also equipped with a blue tooth adapter for transmission of the data in each case between the object identification unit, the information carrier and a corresponding position transmitter, depending on availability or more desired Accuracy global and / or local position data transmitted to the communication device and there to link with the route plan provides.

For example this way, when entering a supermarket, details of the Transfer product offers to your Pocket PC via Blue-Tooth, where they are available to the user stand. The transponders then serve to identify individual, from selected by the user Items. Information can be obtained from the database using the identification code at prices, expiring shelf life, the location within of the supermarket to stock Quantity, for packaging size etc. be issued acoustically as well as directions for the user be made acoustically to the location where the selected product is located located. The user can therefore make targeted purchases without an accompanying person. In the signposting can especially for Blind and partially sighted important clues are included, such as for example, “Caution Level "," Open "or" Closed Passage "and others.

For the department store can thus eliminate the pricing out of the goods because the (daily updated) loaded database (e.g. via the database maintenance of Till) the user the current prices, e.g. via display or acoustically, be communicated.

The Use of this design example is also more interactive Museum, city and exhibition guides possible.

On Another design example is used to locate trees or groups of trees, clearly identify and provide on-site information about a selected tree or a selected one Retrieve tree group or new information in a database store. Here are the trees which in this case correspond to the objects, permanent transponders assigned as object identification units, which in turn the Identify the selected one Tree or a selected one Enable group of trees and which still allow retrieving associated information, stored on an information carrier accessible for data exchange are. This information can for example the geographic data of the tree, cultivation and quality data, Disease data and pests etc.

The Find a selected one Tree is also done here using an identification code from the central information carrier retrievable site plan and its link with position information, which in this case are obtained from a global position transmitter become.

at not available Global position data, as is common in the forest, can be routed through adopted a local system become. For this purpose are in any frequency, however at least Crossroads and other distinctive selection points, such as at boundary stones, local position sensors, e.g. To attach transponders, for example the route plan transmitted to the communication unit via mobile phone guide of the user to the object (here tree) whose coordinates are known. Parallel operation is also possible, as described above.

The Attaching the transponder can be done, for example, by drilling the Tree in the base area, with the transponder in the borehole used and this is then permanently sealed. By the coding stored on the transponder is the tree above its clearly identifiable throughout the entire service life and beyond.

So For example, a forestry employee is able to provide information about diseases and pests on site with the actual Compare conditions and, if necessary, transmit changes to the information carrier and save there.

The Use of the information collected in the information carrier and stored data can be related to planning services, such as new planting, care, management, felling, Rückungs- and waste management, marketing management, etc.

The possible uses range from forest damage mapping to tree cadastre, test execution and general forest management. This includes tree identification for trees that are particularly worth protecting, for example within parks, on avenues, in the city picture integrated trees etc.

The Reading the information of the transponder is still after Logging possible, so here the assignment to the owner or the assignment during transport or in a sawmill can be.

The Invention is not only the design examples, as before described, limited, but Can also be used by tourists and trade fair visitors, if modified accordingly or enable hikers to find their way. You can do that like already shown, both global position sensors and local ones Position transmitter who used the. So as a global position provider for the Orientation outdoors preferably GPS is used for orientation in museums, exhibition halls or other buildings where GPS is not available, local position sensors are used. Is also a parallel operation, as described above, possible.

basis of a control and communication system designed in this way each with the relevant tourist information provided with transponders Goals or exhibits, buildings etc. as well as the information stored in an information carrier and by means of the communication device that a single user or a User group is assigned, retrievable information.

The Communication device in the preferred case is the tourist, Trade fair visitors or other users, for example, for a fee in the city information center, in the exhibition center, etc. There is also a fee-based data transfer to a user's own Device conceivable. As already shown, the signposting is based on the link between the the position data obtainable from the global or local position sensors with the respective to the region, the area or the locality Route plan.

On given locations within a city or museum can be further information carriers, about in the form of "information pillars", of which one specific identifier to be read in, which is assigned to the user Information is retrieved.

The Guidance and transmission of information takes place inside closed rooms or inside buildings, for example, e.g. At the entrance to the room or building, information about a person is arranged from an "information column" arranged there Blue-Tooth adapters are transmitted to the communication device assigned to the visitor.

there information is transmitted which are both for leadership from transponder to transponder that are assigned to the objects, serve and thus at the same time landmarks within the room or the building are. The identification codes stored in the transponders are in the communication facility when passing the object read and prompt the user to the assigned information in one that he can select Language from the information carrier call from. In a special embodiment, it can be provided that the Identification code retrieving the information from the temporarily charged Database that relates to the assigned object or its environment, automatically caused and makes it visually or acoustically available to the user.

In a design variant that when shopping in a department store orientation is made easier for the customer and the Guide to the ones selected by him Products offered. For this purpose, the communication device can, for example attached to a shopping cart or to the customer when entering handed over to the department store be when he's not over your own device features. The customer then has the opportunity from an "information pillar" information about the goods or to load product groups onto the communication device interest him. This is both information to the location or to the signposting as well as information about the Products themselves, such as nutritional information for food, Proof of origin, expiry dates, prices, etc.
