Description

The invention relates to a device for transmitting data concerning authorization information, such. As a parking permit or the like, by means of active radio to a data reading device.

In practice, various methods are known for verifying data relating to an item's subject matter by a controller. In general, there is no ownership relationship between the subject for which a particular matter is to be reviewed and the controller.

The data can be both static and dynamic information such. B. a unique identification number or special parking passes, access permissions, etc. act.

In that regard, z. B. in parking motor vehicles a parking authorization by visual inspection of a designed in the vehicle parking ticket, a resident parking entitlement or a disability card be checked. As the driver of the motor vehicle usually the Parking ticket on the driver's side puts on the dashboard and motor vehicles are usually parked on the right side of the road, the inspector must enter the road to check the parking ticket and is thus endangered by the flowing traffic. It is also a disadvantage that the direct assessment of each motor vehicle this is considered quasi "suspicious" and insofar as the drivers of the vehicles can be unpleasantly affected. Incidents between control persons, such as As road wardens, and drivers are frequent and burden the work of the inspectors.

A disadvantage of information located behind the windshield is that they are only poorly or no longer recognizable from the outside when dirty glazing and / or moisture on the windows.

Furthermore, it is known that via mobile phone can "book" in a paid parking system and thus a parking permit is purchased for a corresponding fee, which is usually then no written confirmation for the parking permit is created. In order to check the parking permit, the control person must then identify the vehicle at a feature and then contact the licensing authority for checking the authorization, which as a rule likewise takes place by means of mobile radio.

The disadvantage here is that the various available identification features are recognizable only at a short distance and also require a clear personal assignment. However, this prevents an economical use of this control method.

Also, passive "tags" are known, which are mounted on the motor vehicle and can be read by means of appropriate communication devices. The passive tags are powered by the reading process with energy, whereby a transmission of the memory content is made possible. However, the range of such passive tags, which is dependent on the antenna size of the reader used, in conventional mobile readers at about 10 to 30 cm very limited, so that the same disadvantages as described above exist, especially in those cases where the tags on a far reaching into the interior of the vehicle dashboard, such. B. in a van or a truck are arranged.

On the other hand, while active tags have a greater range, they are more expensive and expensive, so that their application is limited solely from an economic point of view. A use for equipping parking tickets or the like is thus not worthwhile.

The object of the invention is to avoid the aforementioned disadvantages and to provide a way in which data relating to a situation of an object can be easily checked by a control person and from a certain distance of a few meters. Moreover, it is advantageous if the invention allows use without personal assignment.

This object is achieved by a device for transmitting data by means of active radio to a data reading device, wherein the data are stored on a passive RFId tag and in particular relate to a parking or access authorization and the device a short distance radio transmitter / receiver for reading out the data from the RFId tag and a long-distance radio transmitter for passing the data read from the RFId tag to the data reading device. As a result, a control person can easily check data relating to an object of an object and from a certain distance of a few meters, so that, for example, when parking cars, entering the street is not required.

In particular, the data to be checked may contain both information regarding the subject matter and the subject matter to be examined, and in particular with a tamper protection, such. As an electronic signature or the like, be provided.

Examples of this are parking tickets from parking ticket machines, which not only visually indicate the selected parking space, the valid parking time and parking duration, but also include this information electronically in an integrated transponder. Other examples are handicapped ID cards, residents parking permits etc ..

To ensure the authenticity of the document, this data should be electronically signed. This signature can then be checked by the control system or by the transmission unit. Also, the transmission unit may be provided with an option to provide the moment of close bring the transponder with a timestamp and delete this when taking away again. The time stamp can be executed as a time or as a counter or as a random number.

The user himself brings the device according to the invention in radio contact with a document provided with a transponder, so that the transponder provides the optionally visually readable, previously applied data electronically for reading and checking.

The cost of each parking process are kept low insofar as passive transponders are very inexpensive and the slightly more expensive, designed as an active unit device for transmitting data can be used for several years. The user also has the advantage of using a non-personal or vehicle-related use of the device, even if, for example, the document with the transponder located in or on it is vehicle or person-bound.

However, a reference to a person or a vehicle may be supported at the request of the user. So, if the user z. B. participant in the so-called telephone parking, an association of the device to the vehicle or the holder take place to allow a clear identification for control as well as for billing purposes.

Preferably, a manipulation protection, such. As an electronic signature or the like, be integrated into the device so as to ensure the authenticity of the read data. The data and the connection to and from the device can thus be secured against manipulation, in particular in the form of a so-called electronic or digital signature; In this case, in the communication means of the controlling person, a checking means having corresponding checking and authenticity criteria, and a signature means are provided in the data transmitting means.

Advantageously, can be used to power the device, an electrical power supply, such. As a battery, a battery, a solar battery or a connection to an external power source such. As the power grid of a motor vehicle may be provided.

Furthermore, a detachable or non-detachable connection to the on-board electronics of a motor vehicle can be provided, so that in this way the electrical power supply of the device for transmitting data can be ensured. Furthermore, if each monitoring operation is cached in the control system, it can be determined between two monitors of the same vehicle whether it is the same procedure and, for example, whether the vehicle has been moved in the meantime.

Also, a unique, in particular anonymous identification device may be integrated into the device, so as to be able to check the one possibly official permission of the device for the purpose of use.

Advantageously, a telecommunication device, such. As a GSM module or the like, for data communication over a wireless telecommunications network, be provided. Thus, the data can be achieved, for example, via a mobile Internet access or the like, which is used either by mobile (long-distance radio) or by use of so-called hotspots (short-range radio).

For a universal use of the device according to the invention, this can also be designed for the reception of signals from active tags and / or an interface for external data storage, such. B. USB memory stick, Memory card or a chip in a bank card, credit card, check card or the like.

Advantageously, an actuating device for activating a search mode for finding the data of an RFId tag located in the environment may be provided.

Preferably, the device for the transmission of data may be completely deactivatable, thus enabling anonymity and data protection at times when it is not used for the transmission of data.

The object of the invention is also achieved by a system for checking data relating to a subject to be checked by a control subject of an object, in particular a vehicle, wherein the data to be checked information about the facts to be checked and in particular with a tamper protection such. As an electronic signature or the like, are provided, wherein the system comprises a device according to the invention.

This makes it possible to check the data relating to a subject matter of a subject easily and at a certain distance of a few meters without having to enter the road. The data can be secured against manipulation, in particular in the form of a so-called electronic or digital signature; In this case, a checking device with corresponding checking and authenticity criteria and the device for transmitting data with a signature device are provided in the communication device of the control person.

In this case, the transmission unit can be provided with an on / off function and a pulsed stand-by mode (polling), so that as long as possible operating life of the transponder without replacement or charging of the energy source is ensured by further energy savings. Or the user can deliberately deactivate the transmission unit. In this case, in the stand-by mode, the transponder may also be ready to receive requests only and be fully activated again only upon detection or receipt of a request.

Also, the transmission power of the transmission unit can be optimized in terms of power consumption and range for operation in a vehicle and the safe reading by a controller, so that just a sufficient range is achieved and thus the energy consumption is minimized.

To achieve the object according to the invention also serves a control device for a system of the aforementioned type, wherein a range adjustment is provided. hereby the number of identification means "responding" to a request of the control person is reduced, so that the control person can quickly and without further selecting and finding out the correct requested data from the various data records received.

According to the invention, an indication of the position of the currently checked identification device can be provided, so that in the case of a plurality of data records received in response to a request, the selection of the data set to be checked can be based solely on "geographical" criteria.

In order to achieve the object according to the invention, a central administration point can serve for a system of the aforementioned type, wherein a memory for data regarding a subject to be checked by a control subject of an object, in particular a vehicle, as well as a communication device for communication by short-range radio and / or by Long-distance radio is provided. As a result, such a central administration either for a very large area, such. B. a whole urban area or the like can be used, in which case long-distance radio is used, but it can also be either in addition or only a locally very limited use, eg. B. only for a small number of motor vehicle shelves, made only the short-range radio requires.

In this case, at least one in particular designed as a responder and connected to the memory of the central administration office communication device of the central Administrative body in a street or building furniture such. As parking ticket machine, bollard or barrier system, be integrated so that the short-distance radio query a central billing unit at a parking lot or the like is possible. This is useful for example in so-called real-time billing, in which a parking ticket can be solved for a long period and deposited in the vehicle and, if the paid parking time is not required, a refund of a partial amount can be done.

The control person, who finds in such a case a supposedly valid parking ticket in the motor vehicle, then has to check whether the payment made for this parking ticket may already have been partially reimbursed and the vehicle currently uses the parking area without payment of a user fee.

If appropriate, such transponders or responders even act as a relay station and forward a request by short-distance radio to a central administrative office.

The object according to the invention is furthermore achieved by a method for checking data relating to a fact of an object, in particular a vehicle, which is to be checked by a control person, wherein the data to be checked contain both information concerning the object and the situation to be checked, and in particular with a Tamper protection, such.
