DATA TRANSMISSION

This patent application claims the priority of German Patent Application 10 2018 105 749.0, the disclosure of which is hereby incorporated by reference.

There will be a busbar system for data transmission

specified. Furthermore, a busbar arrangement

specified that has busbar systems for data transmission.

It is desirable to provide a busbar system that is suitable for data transmission. It is still

it is desirable to provide a bus bar assembly having a plurality of bus bar systems for data transmission.

There will be a busbar system for data transmission

specified. A busbar system is used in particular to provide electrical energy and a

Training interface for consumers. One

Busbar system extends for example over a length of several meters. It has, for example, a connection to a power supply network. Electrical consumers such as lights can go along the

Busbar system to be fixed by the

Busbar system to be mechanically held and supplied with electrical energy. According to at least one embodiment, the

Busbar system one along one

Main extension direction elongated extended busbar. The busbar is along the

Main extension direction extended longer than in the

Directions transverse to the main direction of extension. For example, the bus bar is extended 3 m or longer along the main extension direction. The busbar can be fastened in particular to a substrate, for example on a ceiling and / or on a wall. For example, the busbar is attached directly to the ground or suspended mounted and thus spaced from the ground. According to embodiments, a plurality of busbars are arranged one behind the other along the main direction of extent, so that lengths of up to 10 m or more of the

behind one another arranged busbars are covered.

The busbar system has two along the

Main extension extending lines, which are held by the busbar. The two lines are each suitable for transmitting data signals.

For example, the two lines each have one

Cross section of 2.5 square millimeters or more.

For example, the bus bar has a line holder which is formed from an electrically insulating material. The bus bar holds the two leads so that they are accessible at least from one direction from outside the bus bar. In particular, the two lines run in a straight line along the main extension direction.

For example, the two lines are not twisted together. The two lines run, for example, spaced along their entire length straight along the

Main direction. In particular, the two run Lines in the context of manufacturing tolerances parallel to each other. The two lines are each designed to conduct an electrical signal. Thus, the two lines are configured to transmit a data signal, in particular along the extension direction of the lines.

According to at least one embodiment, the

Busbar system on a feed device. The

Feed device has a data input. Of the

Data input can be signaled with a data network. The feed device according to

Embodiments on a data output. The data output can be coupled to the two lines. The

Feed device is designed to feed a data signal at a transfer rate of at least 10 megabits per second in the two lines to transmit the data signal at the transmission rate by means of the two lines along the busbar. For example, a data signal is added to the busbar system via the data input during operation. The feed device feeds the data signal into the two lines so that the data signal can be transmitted via the two lines. For example, the feed device for this purpose performs a modulation and / or another conversion method in order to convert a signal present at the data input in such a way that the transmission by means of the two lines is possible, in particular without significant losses.

The transmission rate of the data signal sent by the

Busbar system is transmitted is at least 10

Megabits per second. In other embodiments, the transmission rate is at least 100 megabits per second.

In particular, the transmission rate corresponds to one Transmission rate of the Ethernet standard. In particular, the transmission rate is greater than the transmission rate used by conventional control signals for light control. For example, it is possible with the

Busbar system to transmit control signals that control the operation of a luminaire, which with the

Busbar system is coupled. For example, the brightness and / or color location of the luminaire are controlled by means of the control signal. The data transfer rate of such

For example, control signals are below 1 megabit per

Second, for example in the range of 1 kilobit per second. By contrast, the feed device and the busbar are designed to realize a faster transmission rate for the data signal by a factor of 100 or a factor of 1000 or more. So it's special

possible, by means of the feed device, a data signal from a data network such as LAN or the like in the

Busbar and in particular in the two lines

feed in order to transmit the data signal by means of the busbar. The data signal thus not only includes

Control data, but is used in particular to wide area network data (WAN)

For example, video stream data, audio stream data, web pages, and / or other data that is transmitted

For example, based on the TCP / IP protocol and / or the UDP protocol are transferable.

In accordance with at least one embodiment, a

Busbar system for data transmission specified. The

Busbar system has one along a

Main extension direction elongated extended busbar. The busbar system has two along the

Main extension extending lines on. The two Lines are each held by the bus bar and are suitable for transmitting data signals. The

Busbar system has a feed device. The feed device has a data input, which can be signal-technically coupled to a data network. The

Feed device has a data output which can be coupled to the two lines. The feed device is designed to feed a data signal at a transmission rate of at least 10 megabits per second into the two lines. Thus, it is possible to transfer the data signal at the transmission rate by means of the two lines along the

Busbar to transfer.

The busbar system can be used for example for the installation of light bands. Luminaire inserts can be mounted at any position along the busbar. The energy supply of the luminaire insert is then done via defined in the busbar running lines.

One of the busbar systems described here is based, inter alia, on the following considerations. A fast wired data connection with a

Transmission rate of at least 10 megabits per second is possible, for example, with an Ethernet system. The

However, the Ethernet system has a star topology where each Ethernet subscriber is at a central point

must be connected. It is not possible to use a continuous cable in the sense of a bus system. For use in a busbar system, the Ethernet line would have to be split at predefined locations to one

Insert participant at this separation point. This

Participants would also need to implement a transit to additional participants in the course of the rail to be able to connect. In addition, Ethernet requires at least four twisted pair and shielded cables.

The busbar system described here now makes use of the idea that the fast

Data connection of at least 10 megabits per second is realized by means of two lines of the busbar. Thus, it is possible to install in addition to the lighting elements and other devices that require a fast data connection. Both a supply of electrical energy and the data connection is realized via the busbar system. Thus, it is possible in particular, a fast

Data transmission by means of the busbar system to

Realize without extra Ethernet cable in the

To provide busbar system, which are not conventional in the busbar system. It is also possible, depending on the technology used, several participants simultaneously connect to the two lines polungsfrei to the participants each to the

Connect data connection. This connection can be made anywhere on the busbar. There is no need to split data lines. The subscribers can be installed anywhere along the busbar and connected to the power supply and the data network. Only two wires from the busbar system are required for the data connection. In particular, it is possible to use two lines that are not connected to the public power grid. These do not have to fulfill any special protocols. Thus, a simple realization of the data transmission by means of the two lines is possible. According to at least one embodiment, the

Busbar system on a filter. The filter is

designed to limit the spread of the data signal. Thus, it is possible to specify in which sections of the busbar system the data transmission is possible.

In particular, it is avoidable that the data signal propagates in areas of the busbar system in which it is not desirable. For example, the filter is on

Low pass filter. Thus, for example, it is possible for alternating current to pass through the filter while the data signal is being filtered and attenuated so that it does not propagate any further.

In accordance with at least one embodiment, the filter is part of the feed device. Thus, it is possible with a few components, a safe busbar system for

Power supply of the coupled in operation with the busbar system participants possible.

In accordance with at least one embodiment, the filter is arranged between the power lines and a power supply network in order to move the busbar system in the direction of the busbar system

Power supply network to filter outgoing data signal. Thus, it is avoidable that the data signal is undesirably forwarded to the power supply network and there unwanted spreads. For example, it is possible that In operation, the data signal is transmitted from the two lines due to induction or similar phenomena to the power lines running parallel to the two lines. By means of the filter it is avoided that the

Data signal from the power lines of the busbar is fed into the supply network.

According to at least one embodiment, a part of

Multiple lines formed, control signals to

transfer. The control signals differ from the data signal, in particular in the transmission rate. The

Transmission rate of the control signals is significantly lower than the transmission rate of the data signal, in particular by a factor of 1000 or more. For example, the

Transmission rate of the control signals in the range of 1 kilobit per second. The control signals are for example

Luminaire control signals, the operation of lights

control, which are coupled in operation with the busbar system. The control signals include, for example, information about a desired brightness, a desired color location, and / or other relevant information that is entered, for example, by a user by means of a switch or another input device. In particular, the control signals can not comprise any information.

According to at least one embodiment, the

Busbar system on a functional use. Of the

Functional insert can be freely positioned with the busbar and can be coupled to hold the functional insert. Of the

Functional use is signal technically connectable to the two lines for transmitting the data signal between the

Feed-in device and the functional insert. The

Busbar system thus provides both a mechanical Mounting interface for the functional use available as well as a data interface for transmitting the

Data signal. The function insert, which is also referred to as a subscriber, is connected to the two lines

any position along the busbar connectable to the data signal between the two lines and the

Function transfer to be able to transfer. For this must

In particular, no line to be separated. A simple contact between contact pins of the

Function insert and the two lines is sufficient to the data signal between the two lines and the

Transfer function assignment.

According to at least one embodiment, the

Functional use an audio system. The data signal comprises, for example, audio signals which are output acoustically by means of the audio system. Alternatively or additionally, the functional insert has a camera system. The data signal includes, for example, video signals generated by the camera system. Alternatively or additionally, the

Functional use a network connection. For example, the functional insert has an Ethernet connection, which is designed, for example, as an 8P8C socket (also called RJ45 socket). Thus it is by means of the

Busbar system possible to transmit a data signal and make it available to any device using conventional Ethernet lines and using the

Network connection is connected to the two lines. Thus, it is possible to use the bus bars as a network cable between the feeder and the network terminal. Thus, it is possible by means of the busbar system to dispense with an additional installation of network cables. According to at least one embodiment, the

Busbar system on a plurality of functional operations. The function inserts are each signal-technically connectable to the two lines for transmitting the data signal between the feeder and the functional inserts. In particular, it is possible to use the functional inserts

at the same time to supply the data signal by means of the two lines. For example, it is possible up to 128

To connect function inserts to the busbar and to provide the data signal.

In accordance with at least one embodiment, the data input is an Ethernet interface. Thus it is possible the

Feed-in device by means of conventional Ethernet cables to connect to a data network. For example, the data input has an 8P8C jack.

According to at least one embodiment, the

Busbar system on a luminaire insert, which can be coupled to the busbar to hold the luminaire insert. The luminaire insert is by means of the busbar with

Electric power supplied. The luminaire insert is held by the busbar and supplied by the busbar with electrical energy, in particular by means of

Power lines of the busbar. For example, the

Luminaire insert connected to the wires, the

Transmit control signals.

Busbar arrangement a plurality of

Busbar systems, which are formed in particular according to one of the described embodiments. The Busbar systems are each by means of the associated feed device with a common

Power supply network connectable. Thus, it is possible to use a plurality of busbars, which extend for example along a common main extension direction or extend in different main directions of extension and are supplied by the common power supply network with electrical energy.

According to at least one embodiment, the

Busbar systems each on the filter. The

Busbar systems are each by means of the associated filter signal technology of the power grid

occurs among each other. In addition, an undesirable

Propagation of the data signals by means of

Power supply network avoidable.

A busbar with two lines is according to a

Embodiment used for data transmission at a transmission rate of at least 10 megabits per second by means of the two lines. A use of the busbar is specified, in which the two lines, in particular along the entire length, run next to one another and at a distance from one another and, in particular, do not cross over or are twisted. In particular, the two lines are not shielded along their entire length in the busbar at least from one direction, so that touching the two lines along the entire busbar is possible. In accordance with at least one embodiment, a use of the power rail for data transmission at a transmission rate of at least 100 megabits per second is specified.

Busbar system according to an embodiment, and

Figure 3 is a schematic representation of a

Busbar arrangement according to an embodiment.

FIG. 1 shows a schematic representation of a

Busbar system 100 according to one embodiment. The busbar system 100 has a busbar 102. The busbar 102 has, for example, a mounting rail which can be mounted, for example, on a building wall, such as a ceiling. The mounting rail is formed, for example, as a metallic semi-open profile tube. The busbar 102 and the mounting rail extend along a main extension direction 101 elongated. Along the main extension direction 101, the bus bar 102 has a greater extent than transversely thereto. For example, the busbar extends along the main extension direction 101 over a length of 3 m or more. A plurality of bus bars 102 can be connected in series along the main extension direction 101

Conductor holder is made in particular of an electric

formed insulating material, for example of a plastic. The conductor holder holds lines 104, 105, L, N, PE. The lines 104, 105, L, N, PE are in particular designed as electrical lines, each one

can conduct electricity and / or transmit electrical signals. Preferably, the

Leads 104, 105, L, N, PE around metallic wires,

for example, made of copper. Preferably, the lines 104, 105, L, N, PE are free of an insulating sheath.

In particular, bare wires are without an electrical one

insulating sheath in the conductor holder of

Bus bar 102 attached. The use of the cables

104, 105, L, N, PE without sheath has the advantage that no removal of a sheath is necessary to provide electrical contact points. The lines 104,

105, L, N, PE can be touched over at least one direction over their entire length or at least over almost their entire length in order to form an electrical contact. The lines 104, 105, L, N, PE are all formed identically according to embodiments. The same type of line is used for all lines 104, 105, L, N, PE. It are no specially trained lines for the

Data lines 104, 105 required.

The two lines 104, 105 extend in particular along the busbar 102 without crossing each other. The two lines 104, 105 extend in particular parallel to one another along the busbar 102. The two lines 104, 105 run in particular not twisted together along the busbar 102nd

The busbar system 100 has a feed device 106. The feed device 106 serves to the

To contact lines 104, 105, L, N, PE according to their intended use. For example, the

Feed-in device 106, the power lines L, N, PE with a power supply network 111, which is in particular a 230 V network. The feeder 106 connects the two lines 104, 105 to a data network 108. The

Data network is in particular a wired network according to an Ethernet standard. According to further embodiments, the data network 108 is a wireless network. The

Feed device 106 then has a corresponding

Wireless interface on to the wireless connection of the

Feed-in device 106 with the wireless network 108.

The feed device 106 has a transformer 103, which has a data input 107. The data input is connected to the data network 108. The data input 107 is an interface between the busbar system 100 and the data network 108. At the data input 107 both Data from the busbar system 100 are transmitted to the data network 108 as well as data from the data network 108 are transmitted to the busbar system 100.

For example, the data input 107 has a socket such as an 8P8C socket for connecting the feeder 106 to the data network 108. For example, a

Ethernet connection between the data network 108 and the feed device 106 is formed.

The feed device 106 and in particular the transformer 103 have a data output 109. The data output 109 is connected to the two lines 104, 105 of the bus bar 102. The transformer 103 is designed to transfer the data of the data input 107 into the two lines 104, 105

feed. Accordingly, data from the lines 104, 105 can be fed into the data network 108 by means of the transmitter 103. For example, the

Infeed device 106 and in particular the transformer 103 is adapted to transmit a data signal in a frequency band from 2 MHz to 68 MHz via the lines 104, 105.

In particular, the feed device 106 and

In particular, the transmitter 103 is adapted to modulate the data signal of the data network 108 or otherwise

to allow transmission via the two lines 104, 105. The transmitter 103 is configured to supply an Ethernet signal to the two lines 104, 105

modulate. The two lines 104, 105 then act

for example, similar to a data hub.

In particular, the feed device 106 allows a data transfer rate of 10 megabits per second or more by means of the two lines 104, 105. By means of the

Infeed device 106, it is possible to use data with a Transfer rate of at least 10 megabits per second along the two lines 104, 105.

In particular, the feed device 106 allows data transmission by means of the two lines 104, 105 without significant losses. The feeding device 106

enables data transmission at the transmission rate of 10 megabits or more by means of exactly the two lines 104, 105. No more lines than the two lines 104, 105 are required. The lines 104, 105 for the

Data transmission at 10 megabits per second or more are designed in accordance with embodiments that the power lines L, N, PE and / or as the lines for

Transmission of control data.

A functional insert 112 is connected to the two lines 104, 105. By means of the lines 104, 105 is a

Data transmission between the functional insert 112 and the feed device 106 possible. Thus, one is

Data transmission between the functional insert 112 and the data network 108 is possible, wherein the data transmission has a data transmission rate of 10 megabits or more. In addition, the functional insert 112 with the

Power lines L, N connected. Thus, it is possible by means of the bus bar 102, both a supply of

Functional insert 112 with electrical energy

to provide as well as the data transmission between the feeder 106 and the functional insert 112 to realize. According to further embodiments, the functional insert 112 is coupled only to the lines 104, 105 for data transmission and not in addition to the power lines L, N. For example, electrical power is also provided by means of the lines 104, 105. Alternatively, it is possible that the functional insert 112 just a data connection needed and no additional power supply.

The functional insert 112 is, for example, a

Network-enabled device such as a computer, an audio system, a camera system, a display system or another system that sends or receives electrical signals, in particular by means of an Ethernet standard. According to others

Embodiments, the functional insert 112 is a

Data interface, with a variety of devices

For example, by means of the Ethernet standard can be connected. In particular, the functional insert 112 has a socket for this purpose or a wireless interface. Alternatively or additionally, the functional insert 112 is an Ethernet connection element with RJ45 socket and PoE (Power over

Ethernet, power supply via Ethernet). A commercially available device can be connected to the RJ45 socket and via PoE using the Ethernet cable with electrical

The PoE converter provided in the functional insert 112 is supplied with electrical energy from the power lines of the busbar system 100, in particular the busbar 102. For example, a functional insert 112 thus operated is a monitoring chamber, a webcam and / or an environmental sensor.

Figure 2 shows the busbar system 100 according to a

another embodiment. The busbar system 100 according to FIG. 2 substantially corresponds to FIG

Busbar system according to the embodiment of Figure 1. In contrast to the embodiment of Figure 1, the busbar system 100 according to Figure 2, a filter 110 on. The filter is in particular a low-pass filter. Of the Filter 110 is particularly adapted to filter data signals. In particular, the filter 110 is part of

Feed device 106. For example, the filter 110 is connected between the power lines L, N, PE and the

Power supply network 111 arranged. The filter 110

thus prevents transmission of the data signals from the bus bar 102 in the power grid 111. The filter

110 is not transparent to the frequencies at which the data transmission in lines 104, 105 occurs.

In operation, data signals from lines 104, 105 may be transmitted to power lines L, N, PE. The filter 110 prevents feeding these transmitted data signals into the power grid 111. Thus, an unwanted propagation of the data signals is avoidable.

FIG. 3 shows a busbar arrangement 200 according to one exemplary embodiment. The busbar arrangement 200 has two busbar systems 100. According to others

Embodiments more than two busbar systems 100 are provided, in particular three or more

Busbar systems 100. The busbar systems 100 of the busbar arrangement 200 are connected to the common

Power supply network 111 connected. The power supply network

111 represents the electrical energy for the

Busbar systems 100 available.

The busbar systems 100 of the busbar assembly 200 may be connected to the common data network 108. According to further embodiments, each

Busbar system 100 connected to its own data network 108. It is also possible that part of the

Busbar systems 100 with a common data network 108 is connected and another part of

Busbar systems 100 is connected to another data network 108.

The busbar system 100A shown by way of example corresponds to the busbar system according to FIG

Embodiment of Figure 2.

The busbar system 100B shown by way of example also essentially corresponds to the exemplary embodiment of FIG. 2. In addition, control lines 116, which are part of the busbar 102, are shown. These can also be present in the further exemplary embodiments according to FIG. 1 and FIG. 2 as well as in busbar system 100A. The control lines 116 are designed to enable a so-called DaLi connection. In particular control signals for the operation of a

Luminaire insert 117 transmitted. The transmission rate of the data on the control lines 116 is, in particular, lower than the transmission rate on the lines 104, 105.

For example, the control signals are applied to the

Transfer control lines 116 at a transfer rate of about 1 kilobits per second.

The luminaire insert 117 is connected to the control lines 116 and to the power lines L, N. Thus, it is possible, during operation electrical energy for the

Luminaire insert 117 by means of the busbar 102nd

provide as well as the control signals that specify an operating mode of the lamp insert 117. In particular, the luminaire insert 117 is not connected to the lines 104, 105 which are used for data transmission at the transmission rate of

at least 10 megabits per second are set up. The Control lines 116 and the two lines 104, 105 are in particular separately formed to each other lines of the bus bar 102. According to further embodiments, the control signals for the lamp insert 117 and the

Data signal transmitted jointly by means of the two lines 104, 105. For example, the signals are modulated onto one another. According to embodiments, the lines 104, 105 for data transmission are alternatively or additionally formed separately from the power lines L, N, PE.

Further functional inserts 112 are connected by means of the busbar 102 to the power supply network 111 and the data network 108, for example an audio system 113, a

Camera system 114 and a network connection 115.

Of course, the illustration is to be understood only as an example. There may be others, less or more

Function inserts 112 may be connected to the bus bar 102.

The majority of functional inserts 112 of the

Busbar system 100B are all connected to the two lines 104, 105, for example. Thus, the

Function inserts 112 with a common data bus

connected. The feeding device 106 allows the

Data transmission between the network 108 and the plurality of functional inserts 112 by means of only the two

Lines 104, 105. The function inserts 112 are freely positionable along the busbar 102 and with the

Lines 104, 105 connectable. The lines 104, 105 are freely accessible uninsulated at least from one side and thus directly contactable by means of contact pins or similar contact elements of the functional inserts 112. Consequently a simple and flexible positioning and installation of the functional inserts 112 is possible.

At one end of the bus bar 102 is the

Feed device 106 mounted. The feeder 106, for example, converts the Ethernet signal from the

existing network 108 um, so that the data signal on the two lines 104, 105 of the bus bar 102 can be used. According to exemplary embodiments, the filter 110 is provided in the power lines L, N, PE, so that no high-speed signals can reach other busbars 102 via the power lines L, N, PE. The filter 110 is

For example, integrated in the feed device 106.

In one application, the functional insert 112 is an Ethernet outcoupler with a standard RJ45 socket to connect commercially available network devices.

The respective filters 110 of the respective feeder 106 prevent transmission of the data signals between the individual busbar systems 100A and 100B. According to

Embodiments, the data signal with the

Transfer rate of 10 megabits or more by means of

Power lines L, N transferred. For example, that will

Data signal modulated on the alternating current.

The busbar system 100 and the

Busbar assembly 200 allows a fast

Data connection over the two lines 104, 105 of the

Lines of the busbar 102.

It is possible that the lines 104, 105 only for

Transmission of the data signal at the transmission rate of 10 Megabit or more can be used. It is also possible that the two lines 104, 105 two lines of the power lines

L, N, PE for powering the functional inserts 112 are. The data signal is thus modulated onto two power lines of the power lines L, N, PE and transmitted by means of the two power lines. The power lines L, N, PE thus serve both for energy transmission and for

Data transfer. It is possible to do this
