Description

COMPUTER NETWORK WITH COMMUNICATION OR DATA TERMINAL SYSTEMS FIELD OF THE INVENTION The invention relates to a computer network with data terminal systems, in particular "work stations and / or server, as established in the classification part of claim 1. BACKGROUND OF THE INVENTION In the computer networks of that kind, the data terminal systems for processing and exchanging data, particularly in the case of the so-called "large area networks" (WANs), are installed in locations that are spatially very far from one another. The stations that connect to a data network and the communication which can also be implemented in a self-evident way by means of communication paths that include satellites or other radio trajectories, admittedly in many cases, have a system identification data terminal that is associated "respectively with a work station or an operator and that can be transmitted from the workstation by me If the data network is transferred to another workstation or to a central server, that information does not allow any indication of any kind so that a terminal system is actually found geographically in the computer network. The knowledge of that class is nevertheless important not only when the repair or modification of the hardware of the station is carried out. More specifically, such operations can not be implemented through the network from a remote location, such as the service in the software. Knowledge of the location of the data terminal system is a matter of importance, in particular for security reasons it is also important to allow a data terminal system to access the network only when it is in a predetermined location. The German patent specification DE 40 41 _ 442 C2 describes such a data processing apparatus, in which, however, a transmission facility that is separate from the data network is additionally necessary, with a Additional transmission path for the location data. SUMMARY OF THE INVENTION An object of the present invention is therefore to provide a data network of the general class established in the initial part of this specification, which provides the possibility of reliably ascertaining the current location of a data terminal system, using simple means and transmitting such location by means of the data network. Based on a computer network 7 as set forth in the classification part of claim 1, this object is achieved by the features cited in the characterizing part of claim 1. The invention encompasses the technical teaching that the connection of stationary network for the data terminal system, is the correct place for -an installation of direct or indirect transmission or transmitter for the identification of the location that is transmitted to the terminal data system and from it together with the identification for the terminal system on network. No additional transmission path and interfaces are required in relation to the data terminal system. In this installation, it is avoided by means of suitable filters that the location data passes over the data network. This, in spite of the joint transportation of the location and useful data, provides that the location data can be acquired by a terminal system and be prepared for the transmission in the network, only in_ the region of the location characterized by such location data. In this regard, the term "data terminal systems" according to the invention is used to denote all the data processing systems that are deployed to the end user - which therefore on the one hand can be achieved by the user and which on the other hand has a separable interface in relation to the data network, for example, it also includes the central and departmental computers to which additional hardware is also connected., the term data terminal system is also proposed to include the communication terminal systems that have as their objective more of the transmission of data and information elements than the processing thereof). Furthermore, the term "terminal system identification" is used to denote both the data identifying a terminal system and also such data denoting a given user of that terminal system. In that regard, those data elements can include both individually and in combination. The latter is the case when the user enters a terminal system, for example by means of a chip card or other information feature, such as a scan of the tip of his finger. They are then added to these data for identification purposes in the network - com will be described in greater detail later - possibly the data related to identification by terminal system (recognition) - but in any case the location data of the system. In the computer network according to the invention, which has means for the automatic acquisition and service of the location data of the terminal data systems, the location and data of the terminal system are linked for the purpose of obtaining an overview accurate about the locations and changes in the locations of any data object or data system and prepare those information elements for purposes of further processing with data processing means. Therefore, the matter according to the invention comprises a system having between three and four logical functional units: a) an external transmission facility for the identification of location in the form of location data that are exclusively available in the data terminal system; b) a transmission facility for user or station identification -according to the data of the terminal system as an ambiguous data terminal system or user identification means, c) a conversion and mixing unit for the location data and the terminal system data that is installed in, or to the terminal system to be monitored or in the external transmission facility for the location data. In that form, the information elements of a) and b) are evaluated and prepared together for further processing. In this respect they receive a data format that allows to pass from the information formed jointly from a) and b) in the direction of 1 data network; and d) optionally a decoding unit in a monitoring station in which the information elements that are transmitted in the network and that are supplied by a) and b) and combine by c), are "decrypted", that is, converted into a simple text information element with respect to the nature and location of the respective terminal system. That decoding unit can be organized as a database in the manner of a "look-up table" in the form of a memory or warehouse, such that the data of the terminal system and the location data are respectively contained in a table that directs the "search table" that contains simple texts (referred to as_ "representation"). In that form, the information elements in question may be currently deployed to the user or may be used for subsequent processing in automatic evaluation procedures or with respect to statistics. The basis for the ways to achieve the objective of the invention that is involved here, is that the location information is received in any case by the data network connection. For that purpose, the identification of the location is transferred to the connected terminal system, in order to "combine with the identification of the terminal unit to give a set of common data with the correct protocol", which can be transmitted to through the network. "It is also possible for the identification of the terminal system, to go from the terminal system to the data network connection in order to combine it in a suitable unit with the location data present in. One condition in both cases is that no identification- of location or external terminal unit pass from the network site of the data network connection, to the procedure to generate the dual information of the identifications.This is avoided by filtering or appropriate selection.In this regard, the appropriate means avoid that the location identifications pass to the network in such a way that they can be linked to the identifications of the remote terminal systems, this is reliably avoided by the local identifications and / or the terminal system that pass over the network so that they can receive from there and join logically in the terminal systems to give combinations of identifications localizacio and the terminal system and transmit them as data sets that are completed in this way over the network. 7 Appropriate filters or switches that interrupt the data connection with the general network are used for that purpose, in particular in a synchronous manner in relation to the outputs of a location identification. In this respect, only the connection to the respective data terminal system is maintained. In this case, the transmission location installation is fixed in a fixed manner to the location of the installation, preferably by means of the so-called "tank unit". In this case, the data connection unit with the functionality of the network maintains direct communication relationships with the terminal system to be monitored by means of standardized network protocols. The transitions (LAN, WAJST, MAN) within the system are of subordinate importance with respect to the mode of operation involved. The data network connection unit and / or the transmission facility for the identification of "location, it has in particular means for the stationary connection to a part of a building or other stationary element. Preferably, critical security elements of that class can only be opened with "a special tool" - In a preferred embodiment, the location transmission facility has a wireless transmitter installation adapted to a receiver provided in the network connection unit of the transmitter. data, such as a transmission unit for location identification - The term data network connection (port) is used herein to denote the possibility of making location information elements available to the data terminal system. functional can be implemented both in the form of a unit that can be connected from the outside to the data terminal system as well as internally, ie, for example, in the main card or the network card of the PCs. In a further advantageous embodiment , the location transmission facility does not support any direct communication relationship with the station In this case, only the data terminal system can call the information elements from the location transmission facility (unidirectionally and bidirectionally) or store it (only bidirectionally) and transport it to the monitoring station . ~ ~ The fixed connection of the connection equipment to the tank connection is crucial in terms of the effectiveness of the installation. It is only in this way that it is possible to ensure that, when the network component moves, the connection equipment does not move, which would make it impossible to provide in-ambiguous locations. The connection equipment is therefore considered as a component part of the wiring system and not as a component part of the components of the network.The tank adapter that is required for that purpose is therefore designed in such a way that it encapsulates The cable connector, which is normally to separate easily from the tank connection with a small portion of the plastic spigot, is itself taken over as a connector of the data transmission function, so that it can not be separated from the tank connection as easily as the original cable connection, the release of the connection is implemented by a special locking mechanism that is operable only with a special tool.Without a corresponding cable the tank adapter is suitable as a blind connector that avoids that the tank connection is used without the connection equipment A data box provided in the tank connection contains ac data erca of the installation location of the network component, which can be read through "the client's SW. This is connected by means of the data connection of the network component. ~ The following points are particularly advantageous in relation to the present invention - with respect to the corresponding developments -: The system can be implemented quickly and can be used independently of the network protocols. When using energy saving components, the expanded data network connection units do not require a power supply of their property since the supply can then be taken from the data network. It is also possible to manage network components without a standard operating system. The illustrated network can also be an energy or power network in which the data is transmitted based on the "data-on-line-of-energy" principle. It is particularly advantageous in this respect that both the energy and the useful data of the network are transmitted together with the identifications of the terminal system and the location on the same data path. BRIEF DESCRIPTION OF THE DRAWINGS Other advantageous developments of the invention are characterized in the appended claims or set forth in greater detail below with the description of the preferred embodiment of the invention with reference to the figures of the accompanying drawings in which: 1 shows as a preferred embodiment of the invention, a computer data network provided with the features according to the invention, Figure 2a shows a block circuit diagram of a first variant of a detail of the embodiment of Figure 1 with the parts, which refer to the invention of a data terminal system with connection to the network, Figure 2b shows a block circuit diagram of a second variant of a detail of the embodiment of Figure 1 with the parts, which refer to the invention, of a data terminal system with connection to the network, Figures 3a and 3b show two views, perspectives of difference Various embodiments of the data network connections provided with features according to the invention, and Figure 4 shows an additional mode in which the data network is combined with the power network and the data transmission is superimposed on the transmission of energy.

DETAILED DESCRIPTION OF THE INVENTION In the case of the computer network 1 shown in Figure 1, several data terminal systems 6 to 9 are arranged spatially separated from each other in different installation locations 2 to 5. The data terminal systems 6 to 9 that preferably form work or service stations, they are connected by means of data network connections 11 to 14 in the form of tanks to ground for a data network 10, by means of which the data exchange takes place. Provided in connections 11 to 14 of the data network are the location transmission facilities, which are set out in greater detail later, as transmission facilities for the identification of in-ambiguous location, which contains an element of information with regarding the installation location of the station. Figure 2a is a block circuit diagram of a first variant of a data terminal system provided with the parts that relate to the invention, showing diagramatically a data processing system 7. The apparatus 7 has a conventional processor system 21 which is combined to form a single block and which is proposed to represent the units and elements provided in the box of a PC that includes local peripherals such as screen, keyboard and printer with hardware and software Relevant Connected to the processor system 21 is a network interface 22 which makes the connection to the data network 10 by means of a connection unit 12 to the data network. In this case the network interface 22 is controlled by the processor system 21 in such a way that the transmission of the data by means of the network is carried out in accordance with the protocols provided in the network. A receiver 23 for the location data LD stores the information elements that were communicated by the transmission facility provided in the connection unit 12 of the nearest data network, with "respect to that location data, and transmits the same. to a converter 24 that stores such data so that it can be transmitted at predetermined times or according to the demand beyond the connection unit 12 to the nearest data network to other data terminal systems connected in the computer network in association with identification of the terminal system DE from a memory or store associated with the station or an operator in a suitable protocol, such as location data LD originating from a given station, location and terminal system data (LD +). DE) that are combined or transmitted in appropriate association are installed in a protocol that is suitable for the transmission of data over the network and differ in e aspect of the pure location and the terminal system LD and DE respectively. The data network connection unit 12 has a control member 26 which controls the flow of data between a connected data terminal 7 and the data network 10, with the inclusion of the location data of the data network. For that purpose, the array has a transmission facility 27 for the location data that contains the location data in a fixed or predetermined manner in some other way.; In an alternative configuration, the location data may also be received by a transmitter 20 installed in a fixed manner placed in the vicinity and converted. In that case, the location transmission facility 27 is in the form of a corresponding receiver that does not originally contain the location data. Instead of this they are contained in the transmitter. The advantage in this respect is, in particular, that the data network connection units can be of a uniform configuration among themselves. A point of particular importance in the illustrated variants is that the location data is emitted by the data network connection unit 12 only in one direction towards the terminal system of data connected thereto. This means that the location data is "protected from the network" as it is. This can be done by means of an adequate time or filtering-frequency, switching or other measures that prevent the propagation of location data to the network. In a corresponding manner, this is also additionally possible by means of additional or the same filtering measures to avoid that the location data that is generated in a remote location and that have been wrongly entered into the network, pass through the unit 12 connection of the data network to the system 7 data terminal. This filtration or protection action 29 is shown diagrammatically in dotted lines in Figure 2a. Location transmission facilities can be transmitters that transmit location data to the data network connection unit by means of "infrared or sound radio waves." In contrast to the tank-to-ground configuration that allows location Differentiated from the system since each connection can be identified individually, the last mentioned variant is limited to the common location information for a plurality of data terminal systems that are "placed in proximity". The location transmission facilities are protected in relation to each other so that multiple associations of a terminal system gives data with a plurality of location transmission facilities are not possible. In figure 2a the other data that are to be transmitted in the network are denoted by D and transported in the usual way between the data terminal system 7 and the network 7L0 by means of the data network connection unit 12. . In this case the bracket DVxnt combines the exchange of data between the data terminal system 7, while the Dvext bracket does the same for the data exchange between the connection unit 12 of the data network and the data network 10. . In FIG. 2b, the block circuit diagram of a second variant of a data terminal system 8 provided with the parts that relate to the invention also has a conventional processor system 21 that combines to form a single block. Connected to that processor system 21 is a network interface 22 which in turn makes the connection to the data network 10 by means of a data network connection unit 13. In this case "the interface 22 of the network is also controlled by the processor system 21, in such a way that the transmission of data by means of the network is carried out in accordance with the protocols that are provided in the network. The data network connection has a control member 26 that controls the flow of data between a connected data terminal system 8 and the data network 10 with the incorporation of data from the data terminal and location system (DE + LD For that purpose the arrangement also has a transmission facility 27 for the location data, which contains the location data in a fixed or predetermined way in some other way. also received by a transmitter 28 installed in a fixed manner placed in the vicinity and converted. In contrast to the modality shown in figure 2a, in this case the DE data of the terminal system produced by the data terminal system 8 are combined with the location LD data by the converter 24 'in the data network 13 unit to provide the terminal system and the combined location data (DE + LD) and send them to the network. - An aspect of particular importance in the alternative configuration shown here is that the data of the terminal system is received by the connection unit 13 to the data network only from the connected data terminal system 8. This means that the data of the terminal system is "kept away from the network" as they are. This can also be done by means of adequate filtration, selection of time switches or other measures that prevent the propagation of data from the terminal system to the network. In a corresponding manner, the same or additional filtering measures may also serve additionally to prevent the ED data of the terminal system occurring at a remote location and being erroneously fed into the network from entering the connection unit 13 to the data network. In addition, no data from the terminal system can reach the "external data network connection unit by means of the data network connection unit .. This filtering or examination 29 'is shown in dotted lines in FIG. 2b In figure 2b the other data that are to be transmitted in the network, are also identified by D and are transported in the usual way between the data terminal system 8 and the network 10 by means of the connection unit 13 to the data network, therefore, while in the modality of the figure 2a the pure location data LD may only be communicated between the data terminal system 8 and the data network connection unit, in the mode of "figure 2b this involves the DE data of the pure terminal system. the complete data set (LD + DE) that can be freely transmitted over the data network This procedure avoids that the defective combinations of terminal system data and location data that occur could simulate a false location of devices. Through the analysis of data at the monitoring station, it is possible to implement the verification in a plausible manner with respect to the location data and data from the data terminal system, as comparable to the inventory data. way to provide data for: statistical analysis operations, inventory procedures, network management, cable and system and security uses In this aspect it is desirable in terms of better In addition, the security measures provide additional lateral structural hardware measures - for example, making it possible to open the tank unit exclusively by means of a key or special tool - or software solutions such as, for example, the need for a keyword questioning co or is used in relation to code locks and other access secured and safeguarded. The term "tank unit" is used herein to designate the connection unit that is filtered on the ground or floor or on the wall and in which the terminal data system is connected by cables to the network local. In general, placed inside this "unit are four adapters that can be used" individually and for "several services, for example telephone and LAN." It is possible to use for this purpose the tank units that are currently available and that can be used. Complemented by an enclosed location transmission facility, or a receiver for a permanently placed location transmitter that is available in the vicinity The first mentioned solution is based on "" the use of existing ground tank procedures. In order to achieve the desired functionality, an "additional location transmission installation module is required, which is fixedly connected in the tank to a suitable adapter and which is releasable only with a special tool. In that case, the data terminal system is connected to the tank to ground only directly, that is to say by means of the location transmission facility. - - The simple location transmission installation comprises a simple electrical or electronic component or device, which returns its location data on demand from the data terminal system. This can be, for example, a simple electrical resistor, a resonant circuit or another electronically searchable memory or reading. Examples with respect to the functional groups that are "determined by the signal values defined in a fixed manner that are variable only in the production of the unit or when the unit is put into operation, are for example the synchronization generators, resistors, and constant voltage or current generators.The modalities of the connections to port are shown in figures 3a and 3b.In the case of the embodiment of figure 3a of a network connection T? e.data which is in the form of an intermediate connector (adapter) 30 in relation to a tank connection, the installation has a Western 31 adapter to receive the connection line to the connected terminal unit and a Western 32 connector for connection to the network-data connection installed in a fixed manner The electronic portion 26 '(see figures 2a and 2b respectively) is shown dotted on the inside. "In order to ensure that the adapter containing the installation of the ransmission for location identification remain stationary in the proposed position, the projection 33 is "reduced in length so that it can not be reached manually". Removal of the adapter 30 is therefore - only possible with a special tool. Another structure is shown in Figure 3b. The illustrated grounding tank 34 has an insert 35 with a Western adapter and a cable connection 36, the insert 35 having the electronic portion 26 '. When the tank connection 34 is installed to a part of a building, the projections 37 and 38 which serve to fix it in place are concealed so that removal is not possible or is possible only with difficulty. If the network used includes a power or power network in which the data is transmitted additionally over the power network, the connection connector to the network forms the power supply connector at the same time. In this case, then the switching means -necessary that separate the flow of energy from the data flow- are provided in relation to the respective data systems. In this case, the power supply of the data terminal system is also carried out together with the exchange of the user and location data by means of one and the same connector. In the embodiment of this class, which is illustrated in FIG. 4, the useful and location data of the data or communication system is transmitted over a power network 1 '. This is referred to as "data-in-a-line-of-energy". In the system shown in FIG. 4, a unitary cable network 10 'transmits both the power or power P as well as the data D. In the illustrated data network, a data terminal system (ESI) 2 is provided in the Ll location. The data terminal system 2 has a data processing portion 201, and a network portion 202. The data carriers that are separated from the network voltage are communicated to the data processing portion 201 by means of a high-pass filter 203"while the network voltage from which the data carrier has been removed is fed to the portion 202 by means of a low-pass filter 204. - In accordance with the foregoing, the data terminal system 2 only needs to be connected "to the connector 205 of the" network of "power or power by means of the connector 206. The corresponding considerations apply with respect to the connected terminal systems The location Ll acquires its individual location data by means of a "location data transmission facility 207, which is connected to the network by means of a high pass filter. The filter 29 provides that the location LD data that occurs in that location remains restricted to the established location and can only be combined by the terminal systems connected to the - - IDs of the terminal system. In a corresponding way, they can not pass foreign or extraneous location data to the part of the data network that is associated with that "location." Therefore, the filtering action is affected by the measurements that are only typical of the data from independently, a corresponding consideration is applied with respect to the identifications DE of the terminal system, therefore it will be apparent that only the LD + DE data therefore contains information elements coming from the identifications of the terminal system and the data of the If the additional data terminal systems are provided at the location Ll, the filter 29 is divided into filters separately for the terminal data identifications that are placed directly on, or downstream of, the adapters. of connector 205 as data network connection units and prevent the identification of the terminal system p Assen from one terminal system to the other within the same location. Filters for location identifications that are to be provided in addition to location boundaries if those identifications are received or are present separately in relation to each terminal system, as is the case with the modalities established so far. The additional locations L2 and L3 are only shown diagrammatically in the figure. A power or power supply station 41 feeds the necessary operating power to the power network 1 'by means of a low pass filter. - Therefore the respective network portions of the connected terminal units are supplied by means of 1 power network while the data exchange with the data processing portions takes place. The units provided with the same references correspond in terms of their function to those previously established. The location LD data is fed into the supply network in a locally restricted mode (by means of adequate filtration) so that the energy components (low frequency) are fed respectively to the network portions of the terminal devices while the data components D - (which are subjected to high frequency modulation or which overlap in some other way) are transmitted between the terminal units and the servers. An important consideration in this regard is once again that the location LD data is "only available in the region of the respective location, while the DE data characterizing the terminal system is only available in the region of the" " respective terminal system.This is achieved by proper filtration. Only the interconnected "LD + DE" data can propagate freely in the data network. This functionality is achieved even if only a single network, mainly the power network, performs all functions for the transmission and separation of the respective data and energy components. These functions are integrated in the respective local installation, so that each terminal system only has to connect by its power supply connector to the power grid in order to be ready for operation. The details of production and transmission of location data via the power grid to the connected terminal units are described in a request filed at the same time for the present applicants. This location data can be used both for identification as well as for location devices connected to the power grid. The invention is not limited in terms of implementation thereof to the preferred embodiments described above. On the contrary, several alternative configurations are possible that make use of the illustrated structure even in configurations of a basically different type.
