Definitions

• the invention relates to an adapter, on which eingangsseitkj a cable and on the output side, at least one further cable is connected, according to the features of the preamble of claim 1.
• hybrid cable hybrid line
• Ethernet standard Ethernet standard
• a voltage of 24 V and a maximum current of 6 A is used as a power supply.
• PoE Power over Ethernet
• the invention has for its object to provide the power provided by the hybrid line common PoE systems available.
• the input-side cable is a hybrid cable and the at least one output-side cable is an Ethernet cable
• the adapter has means for converting the transmission standard of the hybrid cable into the transmission standard of the at least one Ethernet cable.
• the adapter (also referred to as a converter) can be arranged in an automation-typical thin topology and thus supports, starting from a power supply, the operation of a larger number of PoE terminals than would be possible with a pure use of PoE.
• the adapter By means of the adapter, it is possible to transmit the data during the exchange between two devices in the same transmission standard (to be looped through) or to enable a change from a first to another transmission standard.
• the adapter according to the invention has corresponding means which are suitable and intended to provide the input-side data which the adapter receives unchanged on the output side to the connected device.
• these means are suitable and determined to implement the input side data of a given transmission standard in another predetermined transmission standard and provide output side, so that the connected device that works according to this further predetermined transmission standard, this data can receive and process.
• the hybrid cable is connected on the input side via a plug connection to the adapter.
• the hybrid cable on the end of a connector, which can be plugged into a corresponding mating connector of the adapter. This makes a quick and easy connection of the adapter to the hybrid cable possible.
• defective hybrid cables or a defective adapter can be easily replaced in the event of a fault.
• the Internet cable is connected on the output side via a plug connection to the adapter. This results in the same advantages as described above.
• this output side hybrid cable is connected to the adapter. Also this output side hybrid cable can be connected via a plug connection to the adapter.
• FIG 1 shows, as far as shown in detail, in a conventional manner, a hybrid cable 1, which has electrical conductors with which on the one hand energy for a power supply and on the other hand data are transmitted according to a first transmission standard.
• an Ethernet cable 2 is provided, with which there is also a power supply and a data transmission according to a second transmission standard.
• the first transmission standard is completely or partially different from the second transmission standard.
• a power supply of twice 24 V and 6 A is realized by means of the hybrid cable 1 as the first transmission standard.
• the data transfer takes place according to an Ethernet standard.
• the Ethernet cable 2 transmits data and energy, for example, according to the ⁇ standard 802.3af-2003.
• the maximum supply voltage is 48 V, whereby the maximum current consumption of the terminal devices may be 350 mA (for a short time, 400 mA are allowed when switching on).
• the 802.3af standard divides the participating devices into power sourcing equipment (PSE) and consumers (Powered Devices, PD).
• the maximum power output is 15.4 watts.
• the standard assumes that after Lertungspoleen only 12.95 watts of usable power may be included in order not to exceed the maximum power output.
• an adapter 3 is provided to which the necessary amount of energy is supplied via the hybrid cable 1, which is then available to the devices available over the Internet cable are connected to the adapter 3.
• the adapter 3 internally has corresponding means for converting at least the energy supply from the supplied first transmission standard into a further transmission standard which corresponds to the transmission standard with which the devices connected to the adapter 3 via the Ethernet cable 2 operate.
• the first transmission standard for the data supplied to the adapter 3 via the hybrid cable 1 may be the same as that provided to the connected devices via the internet cable 2. In this case, it is sufficient that in the adapter 3, the data lines of the hybrid cable 1 are looped through to the Ethernet cable 2 without conversion.
• the adapter 3 means for implementing the data transmission standard at the input of the adapter 3 are provided in a data transmission standard at the output of the adapter 3.
• the adapter 3 It can be maintained with the adapter 3, the advantage of PoE technology that a power cable can be saved and so even in hard to reach places or in areas where many cables would interfere with Ethernet-connected devices can be installed.
• the power supply to the unit does not need to be supplied separately with a power cord and AC adapter or disconnected with a battery. Instead, the device gets the power over the data network. For this purpose, in addition to the data signals, additional power must be fed into the data line at a central location in the network distributor.
• the adapter 3 (converter) thus forms the end point of a hybrid cabling. From the provided by the hybrid cable 1 supply of power and data (especially Ethernet), the adapter 3 generates a valid PoE, which can be further processed by the connected terminals.
• the advantages here are the introduction of high performance with few losses close to the connected PoE consumers and the use of a hybrid infrastructure. It is important that the adapter 3 must have a Energyietsteliung, especially a 24V-capable PoE injector.
• the exemplary embodiment according to FIG. 2 is based on the same principle as illustrated in FIG. However, this adapter 3 additionally has a further output to which a further hybrid ka can be connected at 4. Also in this case, the further hybrid cable 4 may be firmly connected to the adapter 3 or be detachably connected via a plug connection 7 to the adapter 3.
• the adapter 3 which is designed as a T-adapter, can thus be integrated into a hybrid line structure in this embodiment.
• a hybrid connector 5 in particular a plug
• a hybrid connector 7 in particular a socket
• the advantages here are, in addition to those of the embodiment of Figure 1, an integration into an existing hybrid line structure, also in conjunction with I / O field devices, and the connections of several PoE devices in series, in this case, the adapter 3 still in addition have a 3 port (MAC) switch. To ensure trouble-free integration with the field level, this switch should be IRT-enabled. Not shown in Figures 1 and 2, but with full function of the entire system are devices that at the ends of the cables 1, 2 (and optionally 4) to the connectors 5, 6 (and optionally 7) facing away from the ends are connected.
• MAC 3 port
• the supply of power for the devices to be supplied can be done by so-called Endspan devices (for example, switches) or midspan devices (units between the switch and terminal).
