Data transmission between a transmitter and one of a number of receivers allows data stored in the data base of a central computer to be accessed when the appropriate code is entered

The invention relates to a method for data transmission between at least one transmitter and one or meh eral receiving units, for. example, between computers a (Computer) network, according to which the transmitting unit or to a more selected receiver units at least one Key to access data from a central unit received, which further comprises a message concerning to access data from a financial intelligence unit to a Alarm output device in the respective receiving unit is sent and that the reporting unit an evaluation and optional modification of the data monitored.

The data transmission can be both network attached as also take place wirelessly. Incidentally, conventional Coding conceivable, for example the in the crypto graphy often applied swapping or replacing Zei chen. In the former case, the order of Zei Chen changed, whereas in the replacement method to transmitting characters, a specific algorithm fol quietly, be replaced by other characters.

From WO 96/38 987, such a method is known become. Here are a central computer and a transmitter unit responded that a key ( "public key") to one or more selected receiving units shipped. This key is used, the intended recipient to identify.

In addition, there is an alarm output device in of the respective receiving unit, wherein the reception of the GE whole sent and stored data is displayed. Here, then data is conventionally considering the complete information signal to a receiver or a corresponding receiving unit received.

Under the EP 0,375,330 B1 is a Postversendesystem for processing relevant to the mail processing Information for distribution to the consignor written. To this end, a computerized central Datensta tion and a plurality of mailer stations each Weil computer controllable database provided. The Ver broadcast of keys is not reflected.

Moreover, known from EP 0682318 A1 describes a Data management system. Here the aim is to handles a user to its user data independently be able to control.

The sending e-mail and its acknowledgment is the subject of US-PS 5 293 250. - Finally writes DE 33 03 846 C2 discloses a method for writing electronic mail to an electronic communication system. This may be the aid of an computer network work done.

In addition, methods for data transmission from the are known practice and example in so-called Mailboxes of mobile phones used. Here is a spoken message to a desired recipient transmitted, which listen to them in connection thereto can. Generally this is the matter as settled considered if the information to be communicated to the Recipient has been received. This also applies to the case that it is not certain whether the desired recipient in question Related information has ever noted. A message to the receiver or a monitoring of the ie data transmission will not be. - Here will the Invention total remedy.

The invention is based on the technical problem of providing a specify generic method, which is a control the receiving unit and the receiving units with respect transmitted data allows, namely a total re duziertem effort. Also to a correspondingly shaped Conditioning are provided.

To achieve this object, the invention proposes in a generic method for data transmission between at least one transmitting unit and one or more Receiving units, z. B. between computers a (Computer) network before that the key of a record a database or database, said only this key to the selected (n) Receiving unit (s) is transmitted, that further reporting to the receiver unit, only the dispatch of Key is concerned, and in that the emitted key in an intermediate interposed private memory in the receiving unit is stored, wherein the reporting unit, the message about the Delivery of the key to the message output device so repeated until the key in the temporary memory, for example by means of a keyboard in the reception unit is deleted.

In general, the key is in connection with a Additional message received, the signaling unit also the analysis and optional modification of the transferring Additional message monitored. Consequently, by the deletion operation of the key of the (possibly modified) Data in the central unit does not touch. In which Data set is in accordance with current understanding of a Summary of information of one or more Data fields. This single data field is thus inventory part of the data set, where in general in the same Data fields always the same type information stored will. - In the event that it is in the data base is a common database, can in the corresponding Data fields such as addresses, last names, operations etc. are stored. The availability of the data fields with different (sensor) information of a surveil ceutical or alarm is conceivable followed in Figu renbeschreibung will be discussed.

By means of a database management system can be a address individual data fields or records. The latter are clearly identical with the key or a name tifiable. Thus, for. Example, the record "partners" all Information about the customer or business partner "Partner" contain. - The data set "Sensor<b>1</b>"Like all associated Product information includes.

If the database or database is regularly moderate a relational or multidimensional database. Both versions allow complex linkages of data and thus the data fields with each other. As is known, are, for example, in a relational database Data in the aforementioned data fields, which - as already described - one in its entirety or more data build sentences. Similar records form a relation, wherein between multiple logical relations remuneration (Ver linkages or references) can be created. These Relations form the relational database.

In a multidimensional database that Dimen be sions of a so-called attribute as a quasi status display the file or data considered stronger than a relational database, wherein the attributes a data field as redundancies in the background be moved. Anyway allows the key or the Key field uniquely associated with a data set the database or database. In the context of the invention, exclusively transferred this key and otherwise (idea mally) nothing. Of course, the key also be provided with an additional message, which - as the record - stored in the central unit becomes. In the invention, therefore, only a Key to define a unique record of transmitted the transmitting unit to the receiving unit - and no more. Consequently, the receiving unit or the Receiver after reception of the key directly to the by the key identified zurückgrei record fen. This recourse is done either automatically, and specifically such that the identifi means of the key ed data to the receiving unit of the Zentralein will standardize sent out and temporarily stored there or purely manually by the data from the receiving unit is selected.

The activated from the alarm unit or by the message Alarm output device in the receiver unit provides übli cherweise ensure that the receiver or the receiving unit be notified of the delivery of the key and corresponding alarm emits signals. The aforesaid notification output device can audibly and / or visually work. For example, it is conceivable with a LED (Light Emitting Diode) display to work. Also a picture Screen output is possible. Periodically, however, the reporting output device designed as a voice output device. In this context, the invention further provides that the message and / or additional text as a speech information to the educated as voice output device Meldeaus is transmitted display device of the receiving unit. These Consequently, voice output device includes a sogenann TES data / sound module, which is the binary data as vorlie converts lowing speech information into analog acoustic signals and an electro-acoustic transducer, for example Speaker emits. This data / sound module, it can In the simplest case, a DA (digital / analog) - act converter. Of course there is a Kompri optimization of voice information or message in the central unit in the invention, wherein a decompression takes place in the data / sound module.

Usually, the, send the key will be apt, reporting of the reporting unit to the reception unit or the local alarm output device in time transmitted by the key. Consequently, the (time- Lich) first sent key as it were start signal used for formulating and sending a message. This message is abge usually in the central unit sets. Since the reporting unit regularly with the central unit connected or is a part of it, the dispatch is of the key (directly to the receiving unit and / or the central unit) as a quasi trigger signal for the then to be transmitted message. Because the key as practical table key field not only the necessary Informa tions to define a data record, but in , the address of the recipient or the receiving unit contains, can the message of the reporting unit to be apt receiving unit are received accurately. Of the actual message text or message contents will move the removed CPU.

It is possible, at this point, selectable message texts or define -inhalte. These can be, for example, Setting such means of the transmission unit that the Key or the key field - besides the actual Key code identifying the data to be selected rate and the address of the intended recipient (Emp fang field) - additionally contain a field for the selection of desired message has (message box).

The message to the output device in the receiver unit sent message is achieved according to predetermined time intervals repeatedly, regardless of the in Zvi rule memory of the receiving unit cached Key. Here, the predetermined time intervals can controlled from a central timer, which in general is also connected to the central unit or even is a part. Here, the Message repeated in the context of the invention, to at least for the key corresponding key data - the key code identifying the data set - are deleted in the buffer memory. In general My is a repetition of the message, however, as long as followed until the key including the key code, Message field and receiver field (as well as possibly additional Message) has been deleted. - Of course, is it in the context of the invention, in addition a repeating to define the key, which allows - given different individual messages - in the transmitter unit be repeated.

In other words, only takes place to turn off the Reporting unit and thus the suppression of repeated Mel tions, if the key in the buffer of the Receiving unit has been cleared. This can be a are received, ing person can do, as soon as the means of Keyring sels transmitted data is processed and / or note have been taken.

When receiving multiple messages and key in the Receiving unit, the invention provides a Prioritätenab processing of time of receipt of the aforementioned signals and a summary of the messages in the message unit and / or unit of time before. Under a cooperation Constitution of the messages is meant mostly that individual, the receiving unit reached, messages in the simplest case, are added together in the annunciator unit. A message for this case looks like this that usually will be communicated via the voice output device that n messages have been received, where n is the number of received showing messages and keys. Since message and delivered constitute, impaired key (data) pair, re presented n both the number of messages and the Key.

The reception of the key and the message can be means a connected to the receiving unit Keyboard acknowledge. To this end, the receive unit as a computer unit and the keyboard as input be carried out keyboard. Alternatively, it is also conceivable the receiving unit as a computer unit with a train telephone network connected telephone unit and the keyboard as the input keyboard of the telephone unit and / perform or the computer unit. In each case, an acknowledgment by the keyboard take a form which that the key has been received. This acknowledgment signal either directly to the sending unit (and, of course Lich, the central processing unit) or indirectly via the CPU finally transmitted to the transmitting unit will. It should be emphasized that the aforementioned Acknowledgment signal is not a deactivation of alarm unit corresponds. D. h., As long as the key in the associated intermediate memory is not in the receiving unit has been deleted, is within adjustable SET TIME units repeated a message from the reporting unit to the Alarm output device or voice output device via averages, regardless of whether the reception of the Key and / or the message has been acknowledged or not.

Of course, the above-mentioned deletion of the Keyring sels in the associated buffer of the reception unit also using the described keyboard or Input keyboard done. Also is the realization an external erasing means in the invention. When the telephone unit connected to the telephone network can, in the simplest case, a DTMF (multifrequency election process) phone act, in which individual Numbers represented by tones of different frequencies will. It already can be via the associated Keyboard or input keyboard of such a phone or such a telephone unit an appropriate Quit direction signal transmitted to the sending unit. It is also conceivable over a queried code for deletion to the key in the buffer of the receiving unit to care. - Even easier succeed, if it at the Telephone unit to a device connected to the computer unit or integrated modem (modulator-demodulator) is, which digital electrical signals (from the transmitter unit or the central processing unit) into analog electrical signals (To be fed to the telephone network) converts, or vice versa.

The invention is also a plant for data transmission between at least one transmitting unit and one or more receiver units, as described in claim 10 described.

In the following the invention reference being made to a erläu closer embodiment drawing representing tert. The sole figure schematically illustrates a fiction, modern system for data transmission between at least a transmitting unit and one or more receiving units represent.

In the figure, there are a transmitter unit <b>1</b> and a receiving unit <b>2</b>, Of course, even more transmitter units <b>1</b> and receiving units <b>2</b> realized be. Typically, both transmitting unit<b>1</b> as well as receiving unit <b>2</b> a computer on. In addition, a central processing unit <b>3</b> for storing a database or Database shown. Both the transmitter unit<b>1</b> as well as the receiving unit <b>2</b> are connected to the central processing unit <b>3</b> is joined or connected thereto. After execution may, for example the connection between the three aforementioned assemblies <b>1</b>. <b>2</b> and <b>3</b> both wired (using Verbin necting cables <b>4</b>) And wirelessly (via transmitter / receiver facilities <b>5</b>) Done. Of course, is also a combination of the two aforementioned types of data transmission in the context of the invention. Incidentally, the transmission unit<b>1</b> well received, and as well as the receiving device <b>2</b> also can send data. With other words, can transmit unit <b>1</b> and receiving unit <b>2</b> exchange their function. The central processing unit <b>3</b>, Which also have a computer may, on the other hand is mainly used as a storage medium, naem Lich for individual records of a data base or because database. This database or database may in style be constructed of a coordinate system, wherein to each Da data set a specific coordinate of the (multi-dimensional) Coordinate system corresponds.

In addition there is a central, with the transmitter unit <b>1</b> and receiving unit <b>2</b> and the central processing unit <b>3</b> verbun ferent reporting unit <b>6</b>, This reporting unit<b>6</b> is after off guide for part of the central unit <b>3</b>, Your Operation will be explained in the following. Finally, a central timer <b>7</b> as part of the reporting unit <b>6</b> shown. Of course, also a dis cretan building reporting unit <b>6</b> and time means <b>7</b> in the Meaning a compound of the above two units <b>6</b>. <b>7</b> possible and covered by the invention.

The operation is as follows. In the central processing unit<b>3</b> forming a plurality of records, a data base, said data rates are in turn composed of data fields. These data fields, for example, information on a name, an address and an operation or Parameters of a sensor included. Everyone in the data base stored data can be represented by a key or identifying name unique. In an organization of Data base in the nature of the above-described coordinates system represents the key as it were the Koordi ordinates of the desired set of data on the find coordinates specified location (the database) is and will be made available.

Instead elaborate messages and communications between transmitting unit <b>1</b> and receiving unit <b>2</b> back and near, email, now, the invention provides that only the aforementioned key to define a specific Data record of the data base in the central unit <b>3</b> is transmitted. This key can with an additional object are provided. Accordingly, a successful extremely fast and efficient data transfer. Of the Key is assisted by the transmitter unit <b>1</b> to the receiving unit <b>2</b> via the central unit <b>3</b> transfer. Of course, is also a direct delivery of the transmitting unit <b>1</b> to the receiving unit <b>2</b> possible. Then, However, a parallel transfer of the key from the transmitting unit <b>1</b> to the central unit <b>3</b>,

In addition, a message concerning the dispatch of Key of the financial intelligence unit <b>6</b> a message output device <b>8th</b> in the receiving unit <b>2</b> sent. Of the from the transmitting unit <b>1</b> to the receiving unit <b>2</b> transmitted Key acts so to speak as a trigger signal for the means of the reporting unit <b>6</b> message to be sent. This such succeeds in detail that the key ultimately is a key field that the first place Keycode or corresponding to the key Key data - the name or coordinates - the Dataset contains. In addition, in the context of the Key or key field, a data field of the desired address of the receiving unit <b>2</b> occupied (Reception area) so that the key targets the out chose receiving unit <b>2</b> reached. In addition, the Key also include a field that in the message individual defined and specified (message field). As part of the Invention can consist of different, in the central NIT <b>3</b> stored, signaling alternatives are selected. In addition, can be set via this so-called message field determine whether and at what intervals repeated Reporting of the reporting unit <b>6</b> to the receiving unit <b>2</b> to be delivered. Finally, can a Set repeating the key how often the out Austri message should be repeated. Even a first-time is memory by entering the desired time conceivable.

Anyway, the transmitted key is initially in the receiving unit <b>2</b> a merely indicated cache <b>9</b> cached. In the central unit <b>3</b> results in the reception of the key that the reporting unit <b>6</b> optionally selects the desired message and in Combination with the time unit <b>7</b> for the set Repeats the message makes. In plain language engages the reporting unit <b>6</b> depending on occupancy of the above reporting field back to a selected and desired message and repeatedly sends this to the receiving unit <b>2</b>and until such time as the key in the buffer memory <b>9</b> in the receiving unit <b>2</b> is deleted. The targeted Delivery of this message to the desired receiving unit <b>2</b> is achieved in that the key - in addition to the Message field - including the aforementioned reception field, in which the receiver is clearly marked, and which of the reporting unit <b>6</b> taken to send the message becomes.

Anyway, may be established by the key a a unique assignment of the reporting unit <b>6</b> to receive unit <b>2</b> make, both locally and time. Because the message depending on the content of the buffer <b>9</b> in the receiving unit <b>2</b> with the desired repetition repeats. It takes place Original transmission of the message time after dispatch the key because these speak as a trigger for Message acts. So message and key together form a (data) pair.

If several messages and key in the reception unit <b>2</b> be registered, takes place here a Priori did weird of time of receipt of the above Signals. In addition, the key blank from each generated messages in the message unit <b>6</b> and / or time unit <b>7</b> sum up. This is done in the simplest Case such that the number of messages simple is added and a corresponding message to the sum receiving unit <b>2</b> takes place. If several time Inter valle set for the repetition of messages, can work in their summary so that the sum message with the highest refresh rate to the receiving unit <b>2</b> is transmitted. is of course a repeater with the lowest repetition conceivable.

The reception of the key in the receiver unit <b>2</b> leaves by means of a not explicitly shown Tasta ture of the receiving unit <b>2</b> Acknowledge. In the same way can be carried out upon receipt of the message an acknowledgment signal.

Both acknowledgment signals are usually on the transmission unit <b>1</b> retransmitted. This can also be via the central unit <b>3</b> done. The keyboard may be a conventional input keyboard or an additional input keypad act. It is also conceivable that the reception unit <b>2</b> a connected telephone unit <b>10</b> having, the only (dotted line) is indicated. In this case is or are the connecting line (s) <b>4</b> as telephone line (s) run. Of course, it may be here also (a) mobile track (s) <b>4</b> act. Every if can be in this variant an acknowledgment signal with Using the already existing keyboard of the telephone unit <b>10</b> produce. This takes place particularly elegant in the event, that the telephone unit <b>10</b> after Mehrfrequenzwahl- (DTMF) works.

With recourse to the aforementioned keyboards can also a deletion of the key in the latch <b>9</b> of the receiving unit <b>2</b> be performed. Ie., This deletion can both from the keyboard of the telephone unit <b>10</b> as using the input keyboard of the receiving unit <b>2</b> suc gene. In the former case, it is conceivable as Extinction signal a (fixed or selectable) Keyboard code on the telephone unit <b>10</b> enter. In the latter Case may be similar approach, although of course the option is, instead of a keyboard with a other input device, such as a mouse, to work.

According to the embodiment the procedure is such that the in the central unit <b>3</b> stored message as Sprachinfor mation to the voice output device <b>8th</b> executed Alarm output means <b>8th</b> the receiving unit <b>2</b> transmitted becomes. Accordingly, the message as a voice text is the central processing unit <b>3</b> in front. Them, that is, the message may be in the Setting the Sets of messages in such a way be modified such that the number of in the buffer memory <b>9</b> the receiving unit <b>2</b> accordingly received key is considered. Also, the possibly from the transmitter unit<b>1</b> to the receiving unit <b>2</b> sent additional text can be used as Voice information to the aforementioned Sprachausgabeeinrich tion <b>8th</b> be transmitted. In this speech facility <b>8th</b> is it a combination of Data / sound module with attached electroacoustic Converter. Here, the data / sound module is used to convert the (digital) voice information or credentials in analog acoustic values ​​which subsequent to this via be made the electroacoustic transducer audibly can.

When the connection lines <b>4</b> may involve a data act bus network of a (computer), wherein the means Method described key records if necessary in Link sent with additional news and evaluated will. It is also conceivable that plant illustrated as use alarm device in which a function of input signals, the transmitter unit <b>1</b> a match the key at the receiving unit <b>2</b> transmitted. A Message using the signaling unit <b>6</b> to the signaling output facility <b>8th</b> takes place until the key in the latch <b>9</b> the receiving unit <b>2</b> deleted has been. The key can be used for the outlined applica case of use are designed so that the reception of the unit <b>2</b> retrieve and means of the key identi fied data set, for example to a corresponding Sensor signal at the transmitter unit <b>1</b> corresponds. So is it is conceivable that different records for different union or intermittent sensor signals include, in the receiving unit <b>2</b> can be queried qualified. - As part of a computer network, there are similar Options, namely such that the key for the data transmission required Information Iden fication of the example to be processed record wearing.
