Abstract
The invention relates to a computer network with data or communications end systems which are connected to a data network in order to process data at locations that are spatially remote from one another. Said end systems each comprise an end system identifier which is assigned to the respective data end system. The end system identifier can be transmitted from the data end system to another data end system via the data network, whereby a generator for a location identifier is provided in a data network line unit for the data end system, or a transmission unit for such a location identifier is permanently connected to an external generator in an interactive manner. In addition, at least the generator is permanently connected to the installation site of the data end system. The location identifier can only be transmitted from the data network line unit either to or in a direction of the at least one data end system connected to said data network line unit. A receiver for the location identifier is provided in the data end system, and the location identifier between the data line unit and the terminal unit can be transmitted on a common data path with additional data of the data network.
Description
COMPUTER NETWORK WITH DATA OR
COMMUNICATIONS END SYSTEMS
The invention concerns a computer network with data terminal systems, in particular work and/or server stations, as set forth in the classifying portion of claim 1.
In computer networks of that kind, the data terminal systems for processing and exchanging data, particularly in the case of so-called "wide area networks" (WANs), are installed at locations which are spatially far to very far from each other. The stations which are connected to a data network and the communication of which can self-evidently also be implemented by means of communication paths including satellites or other radio paths, do admittedly in many cases have a data terminal system identification which is respectively associated with a work station or an operator and which can be transmitted from the work station by way of the data network to another work station or to a central server, but that information does not permit any indication whatsoever as to where a terminal system is actually to be found in geographical terms in the computer network. Knowledge of that kind is however important not just when repair to or modification to the hardware of the station is to be effected. More specifically, such operations cannot be implemented over the network from a remote location, like for example service on the software.
Knowledge of the location of the data terminal system is a matter of significance in particular also when for security reasons it is important to permit a data terminal system to have access to the network only when it is at a predetermined location.
German patent specification DE 40 41 442 C2 discloses a data processing apparatus of that kind, in which however a transmitting assembly which is separate from the data network is additionally necessary, with an additional transmission path for the location data.
An object of the present invention is therefore that of providing a data network of the general kind set forth in the opening part of this specification, which affords the possibility of reliably ascertaining the current location of a data terminal system using simple means and transmitting such location by way of the data network.
Based on a computer network as set forth in the classifying portion of claim 1, that object is attained by the features recited in the characterizing portion of claim 1.
The invention embraces the technical teaching that the stationary network connection for the data terminal system is the right place for a direct or indirect transmitting assembly or transmitter for location identification which is transmitted to the data terminal system and from same together with the identification for the terminal system onto the network. No further transmission paths and interfaces in relation to the data terminal system are required.
In this arrangement the location data are prevented by suitable filter means from passing onto the data network. That, in spite of the joint transportation of location and useful data, provides that the location data can be acquired by a terminal system and prepared for transmission onto the network, only in the region of the location which is characterized by such location data.
(In this respect, the term "data terminal systems" in accordance with the invention is used to denote all data-processing systems which are detachable at the user end - which therefore on the one hand can be reached by the user and which on the other hand have a separable interface in relation to the data network.
COMMUNICATIONS END SYSTEMS
The invention concerns a computer network with data terminal systems, in particular work and/or server stations, as set forth in the classifying portion of claim 1.
In computer networks of that kind, the data terminal systems for processing and exchanging data, particularly in the case of so-called "wide area networks" (WANs), are installed at locations which are spatially far to very far from each other.

Knowledge of the location of the data terminal system is a matter of significance in particular also when for security reasons it is important to permit a data terminal system to have access to the network only when it is at a predetermined location.
German patent specification DE 40 41 442 C2 discloses a data processing apparatus of that kind, in which however a transmitting assembly which is separate from the data network is additionally necessary, with an additional transmission path for the location data.
An object of the present invention is therefore that of providing a data network of the general kind set forth in the opening part of this specification, which affords the possibility of reliably ascertaining the current location of a data terminal system using simple means and transmitting such location by way of the data network.
Based on a computer network as set forth in the classifying portion of claim 1, that object is attained by the features recited in the characterizing portion of claim 1.
The invention embraces the technical teaching that the stationary network connection for the data terminal system is the right place for a direct or indirect transmitting assembly or transmitter for location identification which is transmitted to the data terminal system and from same together with the identification for the terminal system onto the network. No further transmission paths and interfaces in relation to the data terminal system are required.
In this arrangement the location data are prevented by suitable filter means from passing onto the data network. That, in spite of the joint transportation of location and useful data, provides that the location data can be acquired by a terminal system and prepared for transmission onto the network, only in the region of the location which is characterized by such location data.
(In this respect, the term "data terminal systems" in accordance with the invention is used to denote all data-processing systems which are detachable at the user end - which therefore on the one hand can be reached by the user and which on the other hand have a separable interface in relation to the data network.
That for example also includes hubs and departmental computers to which additional hardware is also connected. In this respect the term data terminal systems is also intended to include communication terminal systems which have as their aim more the transmission of data and items of information than processing thereof.) Furthermore the term "terminal system identification" is used to denote both such data which identify a terminal system and also such data which denote a given user of that terminal system. In this respect those items of data can occur both individually and also in combination. The latter is the case when the user logs in on the terminal system for example by means of a chip card or other identification feature, such as for example a scan of his fingertip.
There are then added to those data, for identification purposes on the network - as will be described in greater detail hereinafter -possibly the data relating to terminal system identification (recognition) - but at any event the location data of the system.
In the computer network according to the invention having means for automatic acquisition and service of the location data of data terminal systems, location and terminal system data are linked for the purpose of obtaining an accurate overview over the locations and the change in locations of any objects or data terminal systems, and preparing those items of information for further processing purposes with data processing means.
The subject-matter in accordance with the invention therefore comprises a system having between three and four logical functional units:
a) an external transmitting assembly for location identification in the form of location data which are available exclusively at the data terminal system;
There are then added to those data, for identification purposes on the network - as will be described in greater detail hereinafter -possibly the data relating to terminal system identification (recognition) - but at any event the location data of the system.
In the computer network according to the invention having means for automatic acquisition and service of the location data of data terminal systems, location and terminal system data are linked for the purpose of obtaining an accurate overview over the locations and the change in locations of any objects or data terminal systems, and preparing those items of information for further processing purposes with data processing means.
The subject-matter in accordance with the invention therefore comprises a system having between three and four logical functional units:
a) an external transmitting assembly for location identification in the form of location data which are available exclusively at the data terminal system;
b) a transmitting assembly for the user or station identification as terminal system data as an unambiguous data terminal system or user identification means, c) a mixing and conversion unit for the location data and terminal system data, which are arranged in or at the terminal system to be monitored or in the external transmitting assembly for the location data. In that way the items of information from a) and b) are brought together, evaluated and prepared for further processing. In that respect they receive a data format which permits passing of the information formed jointly from a) and b) in the direction of the data network; and d) optionally a decoding unit at a monitoring station at which the items of information which are transmitted in the network and which are supplied by a) and b) and combined by c) are "decrypted", that is to say converted into an item of plain text information relating 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 store, in such a way that the terminal system data and the location data are respectively contained in a table which address the "look-up-table" containing plain texts (referred to as "mapping"). In that way the items of information in question can be currently displayed to the user or can be used for subsequent processing in automatic evaluation procedures or in regard to statistics.
The basis for the ways of achieving the object of the invention, which are involved here, is that the location information is received in any case by the data network connection. For that purpose, the location identification is passed to the connected terminal system in order there to be combined with the terminal unit identification to give a common data set with the correct protocol, which can be transmitted over the network. It is also possible for the terminal system identification to go from the terminal system to the data network connection in order there to be combined in a suitable unit with the location data present there. A
condition in both cases is that no alien location or terminal unit identification passes, from the network side of the data network connection, into the procedure for generating the dual information from said identifications. That is prevented by suitable filtering or selection.
In this respect, suitable means prevent location identifications passing into the network in such a way that they can be joined to the terminal system identifications of remote terminal systems.
That is reliably prevented by localizational and/or terminal system identifications passing onto the network so that they can be received from there and logically linked in terminal systems to give combinations of localizational and terminal system identifications and transmitted as data sets which are completed in that way, onto the network.
Suitable filters or switches are used for that purpose, which interrupt the data connection with the overall network in particular synchronously in relation to the output of a location identification.
In that respect only the connection to the respective data terminal system is maintained. In that case the location transmitting assembly is fixedly anchored to the installation location, preferably by means of a so-called "tank unit".
In this case data connection unit with network functionality maintain direct communication relationships with the terminal system to be monitored by way of standardized network protocols.
Transitions (LAN, WAN, MAN) within the system are of subordinate significance in regard to the mode of operation involved.

Transitions (LAN, WAN, MAN) within the system are of subordinate significance in regard to the mode of operation involved.
The data network connection unit and/or the transmitting assembly for the location identification has in particular means for stationary connection to a part of a building or another stationary element. Preferably security-critical elements of that kind can only be opened with a special tool.
In a preferred embodiment the location transmitting assembly has a wireless transmitter assembly adapted to a receiver provided in the data network connection unit, as a transmission unit for the location identification.
The term data network (port) connection is used here to denote the possibility of making the items of location information available to the data terminal system. The functional group can be implemented both in the form of a unit which can be connected from the exterior to the data terminal system and also internally, that is to say for example on the motherboard or the network card of PCs.
In a further advantageous embodiment the location transmitting assembly does not support any direct communication relationships with the monitoring station. In this case then only the data terminal system can call up items of information from the location transmitting assembly (unidirectionally and bidirectionally) or store same (only bidirectionally) and convey same to the monitoring station.
The fixed connection of the connection kit to the tank connection is crucial in terms of the effectiveness of the arrangement. It is only in that way that it is possible to ensure that, when the network component is moved, the connection kit is not also moved, which would make it impossible to provide for unambiguous locating. The connection kit is therefore to be considered as a component part of the cabling system, and not as a component part of the network component.

The connection kit is therefore to be considered as a component part of the cabling system, and not as a component part of the network component.
The tank adapter which is required for that purpose is therefore so designed that it completely encapsulates the cable plug which is normally to be easily separated from the tank connection with a small plastic tongue portion. It itself takes over as a plug the function of data transmission. So that it cannot be separated from the tank connection as easily as the original cable plug, release of the connection is to be implemented by a special closing mechanism which is actuatable only with a special tool.
Without a corresponding cable the tank adapter is suitable as a blind plug which prevents the tank connection being used without the connection kit.
A data box provided in the tank connection contains data about the installation location of the network component, which can be read out by means of the client-SW. It is connected by way of the data connection of the network component.
The following points are particularly advantageous in relation to the present invention - in regard to corresponding developments The system can be quickly implemented and can be used independently of network protocols.
When using power-saving components the expanded data network connection units do not require a power supply of their own as 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 may also be an energy or power network in which the data are transmitted on the basis of the "data-on-powerline" principle. It is particularly advantageous in this respect that then both the energy and also the useful data of the network are transmitted together with the location and terminal system identifications over the same data path.

Other advantageous developments of the invention are characterized in the appendant claims or are set forth in greater detail hereinafter together with the description of the preferred embodiment of the invention with reference to the Figures of the accompanying drawing in which:
Figure 1 shows as a preferred embodiment of the invention a computer data network provided with the features in accordance with 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 concern the invention, of a data terminal system with network connection, Figure 2b shows a block circuit diagram of a second variant of a detail of the embodiment of Figure 1 with the parts, which concern the invention, of a data terminal system with network connection, Figures 3a and 3b shows two perspective views of different embodiments of data network connections provided with features in accordance with the invention, and Figure 4 shows a further embodiment in which the data network is combined with the energy network and data transmission is superimposed on energy transmission.
In the case of the computer network 1 shown in Figure 1, various data terminal systems 6 through 9 are disposed spatially separated from each other at different installation locations 2 through 5.
The data terminal systems 6 through 9 which preferably form work or server stations are connected by way of data network connections 11 through 14 in the form of ground tanks to a data network 10 by way of which data exchange takes place. Provided in the data network connections 11 through 14 are location transmitting assemblies which are set forth in greater detail hereinafter, as transmitting assemblies for unambiguous location identification, which contains an item of information regarding the installation location of the station.
The Figure 2a block circuit diagram of a first variant of a data terminal system provided with the parts which concern the invention diagrammatically shows 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 intended to represent the units and elements provided in the casing of an PC including local peripherals such as screen, keyboard and printer with relevant hardware and software. Connected to the processor system 21 is a network interface 22 which makes the connection to the data network 10 by way of a data network connection unit 12. In this case the network interface 22 is controlled by the processor system 21 in such a way that transmission of the data by way of the network is effected in accordance with the protocols provided in the network.
A receiver 23 for the location data LD stores the items of information which are communicated by the transmitting assembly provided in the nearest data network connection unit 12, in respect of those location data, and transmits same to a converter 24 which stores those data so that they can be transmitted at predetermined times or on demand beyond the nearest data network connection unit 12 to other data terminal systems connected in the computer network in association with a terminal system identification ED from a memory or store 25 associated with the station or an operator, in a suitable protocol, as location data LD originating from a given station. The location and terminal system data (LD+ED) which are combined or transmitted in suitable association are assembled in a protocol which is suitable for the transmission of data on the network and they differ in that respect from the pure location and terminal system data LD and ED respectively.
The data network connection unit 12 has a control member 26 which controls the flow of data between a connected data terminal system 7 and the data network 10, with the inclusion of the location data thereof. For that purpose the arrangement has a transmitting assembly 27 for the location data, which contains the location data in fixedly set form or predetermined in some other fashion.
In an alternative configuration, the location data can also be received by a fixedly mounted transmitter 20 disposed in the proximity, and converted. In that case the location transmitting assembly 27 is in the form of a corresponding receiver which does not originally contain the location data. Instead of that 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 amongst themselves. A point of particular significance in the illustrated variant is that the location data are outputted by the data network connection unit 12 only in a direction towards the data terminal system connected thereto. This means that the location data as such are "shielded from the network".
That can be effected by means of suitable time or frequency filtering, switches or other measures which prevent propagation of the location data towards the network. In a corresponding fashion, it is additionally also possible by means of further or the same filter measures to prevent location data which are generated at a remote location and which have been erroneously introduced into the network passing by way of the data network connection unit 12 to the data terminal system 7. That filtering or shielding action 29 is shown diagrammatically in broken line in Figure 2a.
The location transmitting assemblies can be transmitters which transmit the location data to the data network connection unit by way of radio, infrared or sound waves. In contrast to the ground tank configuration which permits differentiated system localization as each connection can be individually identified, the last-mentioned variant is limited to common location information for a plurality of data terminal systems which are disposed in the proximity. The location transmitting assemblies are shielded relative to each other so that multiple associations of a data terminal system with a plurality of location transmitting assemblies are not possible.
In Figure 2a the other data which are to be transmitted in the network are denoted by D and are transported in the usual manner between the data terminal system 7 and the network 10 by way of the data network connection unit 12. In this case the bracket DV;~t combines the data exchange between the data terminal system 7 while the bracket DVeXt does the same for the data exchange between the data network connection unit 12 and the data network 10.
In the Figure 2b block circuit diagram of a second variant of a data terminal system 8 provided with the parts which concern the invention, there is also a conventional processor system 21 which is combined 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 way of a data network connection unit 13. In this case the network interface 22 is also controlled by the processor system 21 in such a way that data transmission by way of the network is effected in accordance with the protocols which are provided in the network.
The data network connection unit 13 has a control member 26 which controls the flow of data between a connected data terminal system 8 and the data network 10 with the incorporation of the data terminal system and location data (ED+t_D). For that purpose the arrangement also has a transmitting assembly 27 for the location data, which contains the location data in fixedly set form or predetermined in some other fashion. In a variant the location data can also be received by a fixedly mounted transmitter 28 disposed in the proximity, and converted.
In contrast to the embodiment shown in Figure 2a, in this case the terminal system data ED produced by the data terminal system 8 is combined with the location data LD by the converter 24' in the data network connection unit 13, to afford the combined terminal system and location data (ED+LD), and outputted onto the network.
An aspect of particular significance in the alternative configuration shown herein is that the terminal system data are received by the data network connection unit 13 only from the connected data terminal system 8. That means that the terminal system data as such are "kept away from the network". That can also be effected by suitable filtering, time selection, switches or other measures which prevent propagation of the terminal system data towards the network.
In a corresponding fashion, further or the same filter measures can additionally also serve to prevent terminal system data ED which are produced at a remote location and which are erroneously fed into the network from passing into the data network connection unit 13. In addition no terminal system data ED can reach the alien data network connection unit by way of the data network connection unit. That filtering or screening 29' is shown in broken line in Figure 2b. In Figure 2b the other data which are to be transmitted in the network are also identified by D and are transported in the usual manner between data terminal system 8 and network 10 by way of the data network connection unit 13.
Figure 1 shows as a preferred embodiment of the invention a computer data network provided with the features in accordance with 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 concern the invention, of a data terminal system with network connection, Figure 2b shows a block circuit diagram of a second variant of a detail of the embodiment of Figure 1 with the parts, which concern the invention, of a data terminal system with network connection, Figures 3a and 3b shows two perspective views of different embodiments of data network connections provided with features in accordance with the invention, and Figure 4 shows a further embodiment in which the data network is combined with the energy network and data transmission is superimposed on energy transmission.

The data terminal systems 6 through 9 which preferably form work or server stations are connected by way of data network connections 11 through 14 in the form of ground tanks to a data network 10 by way of which data exchange takes place. Provided in the data network connections 11 through 14 are location transmitting assemblies which are set forth in greater detail hereinafter, as transmitting assemblies for unambiguous location identification, which contains an item of information regarding the installation location of the station.

In a variant the location data can also be received by a fixedly mounted transmitter 28 disposed in the proximity, and converted.
In contrast to the embodiment shown in Figure 2a, in this case the terminal system data ED produced by the data terminal system 8 is combined with the location data LD by the converter 24' in the data network connection unit 13, to afford the combined terminal system and location data (ED+LD), and outputted onto the network.
An aspect of particular significance in the alternative configuration shown herein is that the terminal system data are received by the data network connection unit 13 only from the connected data terminal system 8. That means that the terminal system data as such are "kept away from the network". That can also be effected by suitable filtering, time selection, switches or other measures which prevent propagation of the terminal system data towards the network.
In a corresponding fashion, further or the same filter measures can additionally also serve to prevent terminal system data ED which are produced at a remote location and which are erroneously fed into the network from passing into the data network connection unit 13. In addition no terminal system data ED can reach the alien data network connection unit by way of the data network connection unit. That filtering or screening 29' is shown in broken line in Figure 2b. In Figure 2b the other data which are to be transmitted in the network are also identified by D and are transported in the usual manner between data terminal system 8 and network 10 by way of the data network connection unit 13.
While therefore in the embodiment of Figure 2a the pure location data LD can be communicated only between the data terminal system 8 and the data network connection unit, in the embodiment of Figure 2b this involves the pure terminal system data ED. It is only the complete data sets (LD+ED) that can be freely outputted onto the data network. That procedure prevents defective combinations of terminal system data and location data being produced, which would simulate a false apparatus location.
By means of data analysis in the monitoring station, it is possible to implement plausibility checking in respect of location data and data terminal system data, as is comparable to inventory data. It is possible in that way to provide data for: statistical analysis operations, stocktaking procedures, network, cable and system management, and security uses.
In that respect it is desirable in terms of enhancing security to provide at the connection side additional structural hardware measures (for example making it possible to open the tank unit exclusively by means of a key or a special tool) or also software solutions such as for example the necessity for a password interrogation as is used in relation to code locks and other safeguarded and secured accesses.
The terms "tank unit" is used here to designate the connection unit which is fitted in the ground or floor or on the wall and at which the data terminal system is connected by means of cables to the local network. In general disposed within that unit are four structuredly connected sockets which can be used individually and for various services (for example telephone and LAN).
It is possible to use for that purpose tank units which are available at the present time and which can be supplemented by an included location transmitting assembly or a receiver for a fixedly disposed location transmitter which is disposed in the proximity.

It is possible to use for that purpose tank units which are available at the present time and which can be supplemented by an included location transmitting assembly or a receiver for a fixedly disposed location transmitter which is disposed in the proximity.
The first-mentioned solution is based on the use of existing ground tank procedures. In order to achieve the desired functionality, an additional location transmitting assembly module is required, which is fixedly connected at 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 ground tank only indirectly, that is to say by way of the location transmitting assembly.
A simple location transmitting assembly comprises a simple electrical or electronic component or device which gives back its location data on request from the data terminal system. That can be for example a simple electrical resistor, a resonant circuit or another electronically interrogatable read only memory.
Examples in regard to functional groups which is determined by fixedly defined signal values which are variable only upon production of the unit or when the unit is brought into operation are for example clock generators, resistors and constant voltage or current generators. Embodiments of port connections are shown in Figures 3a and 3b. In the case of the Figure 3a embodiment of a data network connection which is in the form of an intermediate plug (adapter) 30 in relation to a tank connection, the arrangement has a Western socket 31 for receiving the connection line to the connected terminal unit and a Western plug 32 for connection to the fixedly installed data network connection. The electronic portion 26' (see Figures 2a and 2b respectively) is shown in broken line in the interior. In order to ensure that the adapter containing the transmitting assembly for the location identification remains stationarily at the intended position, the projection 33 is reduced in length so that it cannot be reached manually. Removal of the adapter 30 is therefore possible only with a special tool.

Removal of the adapter 30 is therefore possible only with a special tool.
Another structure is shown in Figure 3b. The ground tank 34 illustrated there has an insert 35 with a Western socket and a cable connection 36, the insert 35 having the electronic portion 26'.
When the tank connection 34 is mounted to a part of a building, flanges 37 and 38 which serve for fixing it in place are concealed so that removal is not possible or is possible only with difficulty.
If the network used involves an energy or power network in which the data are additionally transmitted on the energy network, the network connection plug forms at the same time the power supply plug. In this case then the necessary switching means which separate the flow of energy from the flow of data are to be provided in relation to the respective data systems. In that case power supply of the data terminal systems is also effected together with the exchange of useful and localization data, by way of one and the same plug.
In the embodiment of that kind, which is illustrated in Figure 4, the useful and location data of the data or communication system are transmitted on an energy network 1'. That is referred to as "data-on-powerline". In the system shown in Figure 4, a unitary cable network 10' transmits both the energy or power P and also the data D.
In the illustrated data network, a data terminal system (ES1) 2 is provided at the location L1. The data terminal system 2 has a data processing portion 201 and a network portion 202. The data carriers which are separated from the network voltage are communicated to the data processing portion 201 by way of a high pass filter 203 while the network voltage from which the data carrier has been removed is fed to the network portion 202 by way of a low pass filter 204. Accordingly the data terminal system 2 only needs to be connected to the plug socket 205 of the energy or power network by way of the plug 206. A corresponding consideration applies in regard to the connected terminal systems.
The location L1 acquires its individual location data by way of a location data transmitting assembly 207 which is connected to the network by way of a high pass filter. The filter 29 provides that the location data LD which are produced in that location remain restricted to the stated location and can only there be combined by the connected terminal systems with the terminal system identifications ED. In a corresponding fashion, no extraneous or alien location data can pass into the part of the data network, which is associated with that location. The filtering action is therefore effected by measures which are only typical of location data on their own. A corresponding consideration applies in regard to the terminal system identifications ED. It will be apparent therefore that only the data LD+ED which therefore contain items of information from terminal system identifications and location data can be freely propagated in the network.
If further data terminal systems are provided at the location L1 the filter 29 is divided into filters separatedly for the terminal data identifications which are disposed directly in or downstream of the plug sockets 205 as data network connection units and prevent terminal system identifications passing from one terminal system to the other within the same location. The filters for the location identifications are to be provided further at the limits of the location if those identifications are received or are present separately in relation to each terminal system, as is the case with the embodiments set forth hereinbefore.
Further locations L2 and L3 are only diagrammatically shown in the Figure. An energy or power supply station 41 feeds the necessary operating power into the energy network 1' by way of a low pass filter.
When the tank connection 34 is mounted to a part of a building, flanges 37 and 38 which serve for fixing it in place are concealed so that removal is not possible or is possible only with difficulty.
If the network used involves an energy or power network in which the data are additionally transmitted on the energy network, the network connection plug forms at the same time the power supply plug. In this case then the necessary switching means which separate the flow of energy from the flow of data are to be provided in relation to the respective data systems. In that case power supply of the data terminal systems is also effected together with the exchange of useful and localization data, by way of one and the same plug.
In the embodiment of that kind, which is illustrated in Figure 4, the useful and location data of the data or communication system are transmitted on an energy network 1'. That is referred to as "data-on-powerline". In the system shown in Figure 4, a unitary cable network 10' transmits both the energy or power P and also the data D.
In the illustrated data network, a data terminal system (ES1) 2 is provided at the location L1. The data terminal system 2 has a data processing portion 201 and a network portion 202. The data carriers which are separated from the network voltage are communicated to the data processing portion 201 by way of a high pass filter 203 while the network voltage from which the data carrier has been removed is fed to the network portion 202 by way of a low pass filter 204. Accordingly the data terminal system 2 only needs to be connected to the plug socket 205 of the energy or power network by way of the plug 206. A corresponding consideration applies in regard to the connected terminal systems.
The location L1 acquires its individual location data by way of a location data transmitting assembly 207 which is connected to the network by way of a high pass filter. The filter 29 provides that the location data LD which are produced in that location remain restricted to the stated location and can only there be combined by the connected terminal systems with the terminal system identifications ED. In a corresponding fashion, no extraneous or alien location data can pass into the part of the data network, which is associated with that location. The filtering action is therefore effected by measures which are only typical of location data on their own. A corresponding consideration applies in regard to the terminal system identifications ED. It will be apparent therefore that only the data LD+ED which therefore contain items of information from terminal system identifications and location data can be freely propagated in the network.
If further data terminal systems are provided at the location L1 the filter 29 is divided into filters separatedly for the terminal data identifications which are disposed directly in or downstream of the plug sockets 205 as data network connection units and prevent terminal system identifications passing from one terminal system to the other within the same location. The filters for the location identifications are to be provided further at the limits of the location if those identifications are received or are present separately in relation to each terminal system, as is the case with the embodiments set forth hereinbefore.
Further locations L2 and L3 are only diagrammatically shown in the Figure. An energy or power supply station 41 feeds the necessary operating power into the energy network 1' by way of a low pass filter.
Therefore the respective network portions of the connected terminal units are supplied by way of the energy network while data exchange takes place with the data processing portions. The units provided with the same references correspond in terms of their function to those set forth hereinbefore. The location data LD are fed into the supply network in locally restricted mode (by means of suitable filtering) so that the (low-frequency) energy components are respectively fed to the network portions of the terminal apparatuses while the data components D (which are subjected to high frequency modulation or which are superimposed in some other fashion) are transmitted between the terminal units and servers. An important consideration in this respect is once again that the location data LD are available only in the region of the respective locality while the data ED which characterize the terminal system are available only in the region of the respective terminal system. That is achieved by suitable filtering. Only the interconnected data "LD+ED" can be freely propagated on the data network. That functionality is achieved although only a single network, namely the energy network, performs all functions for transmission and separation of the respective data and energy components. Those functions are integrated into the respective house installation so that each terminal system only has to be connected by its power supply plug to the energy network in order to be ready for operation. The details of production and transmission of location data by way of the energy network to connected terminal units is described in an application filed at the same time to the present applicants. Those location data can serve both for identifying and also locating apparatuses connected to the energy network.
The invention is not limited in terms of implementation thereof to the above-described preferred embodiments. On the contrary, a number of alternative configurations are possible, which make use of the illustrated structure even in configurations of a basically different kind.
