Description

The invention relates to a cable transition for connecting a plurality of signal lines arriving at a first signal processing unit arranged on a first carrier and having a plurality of signal lines extending from a second carrier arranged to be pivotable with respect to the first carrier, comprising one between the two signal processing units extending connection cable, wherein the first signal processing unit comprises a first multi-channel signal converter, which converts incoming on the incoming signal lines measuring monitoring and / or control signals into a transferable via the connecting cable bundled transmission signal and the signal output is connected to the one end of the connecting cable and wherein the second signal processing unit comprises a second multichannel signal converter serving as a signal-to-repeater connected to the other end of the connection cable communicates at its outputs to the original measurement, monitoring and / or control signals corresponding signals.

Flexible cable transitions are often used as an electrical connection element between a stationary support, for example a door frame, and a mobile, in particular pivotable support, eg a door wing, which is movable in comparison thereto (see DE 31 05 311 C2 ; DE 298 14 952 U1 ). They are also known as separable cable transitions in various embodiments, (eg DE 94 16 940 U1 ; DE 100 53 153 C1 ; DE 101 26 785 A1 ; DE 10 2004 047 001 B4 ). If a plurality of lines are connected to one another via a cable transition, the narrowness in the region of the door rebate of accommodating larger plug-in connections with a multiplicity of pin or socket elements is in contrast with separable cable transitions. It has been helped by the simultaneous installation of several, usually multi-wire cable transitions along the edge of the frame. In addition, the available clear inside diameter limits of the protective jacket, the number of lines without affecting the flexibility.

On the other hand, rooms and buildings are increasingly equipped with remote control, monitoring and monitoring devices which must be connected to a corresponding control center. For this purpose, so far has been installed in the walls of the room junction boxes for the measuring, control and input devices and connected by means of laid lines with the control unit. Extensive and time-consuming installation work is required to lay the cables and install the appliance boxes, provided that no prefabricated installation walls are available. It is usually particularly difficult with a subsequent extension or conversion of the control and monitoring system. The installation effort can be considerably reduced if one attaches at least a part of the measuring, control or input devices not on a wall but on the door and connects via a flexible cable transition to a pre-routed, multi-core connection line to the control center. It is much easier to attach additional or newly equipped measuring, control and input devices to a door than to a wall. In extreme cases, you can replace the door and replace it with an appropriately equipped new door. But this requires either multi-core or multiple cable transitions.

The number of cores in the flexible connection cable may vary according to the EP 2 146 401 A2 or the DE 42 22 321 A1 be reduced by the use of signal converters. As a result, the thinnest possible and flexible connection cable is achieved. The signal converter are located in the EP 2 146 401 A2 not in the electronic modules of the two carriers (dashboard or door) but are an integral part of the cable transition and are housed, for example, in the brackets for the ends of the flexible connection cable. As a result, a cable transition is created, which is used not only between the door and the door frame or windows but on any carriers which are relatively movable, in particular pivotable.

Such a cable transition is equipped for the transmission of a variety of arbitrary signals and accordingly versatile. Its mechanical structure and its space requirement correspond to those of a conventional cable transition, so that it is also suitable for retrofitting existing systems and is easy to install. This is particularly advantageous in security systems for monitoring windows or doors.

The measurement, control and monitoring signals - hereinafter referred to as "signals" for short - are provided at the transmitter end of the cable transition, e.g. on the door, implemented by means of a first multi-channel signal converter in a bundled transmission signal, which is fed for example in a single, for example, two-wire line of the flexible connection cable. On the receiving side, e.g. At the door frame, provided at the local end of the cable transition second multi-channel signal converter (retransformer) generates at its outputs the original "signals" corresponding measurement, control or monitoring signals, which are evaluated and processed in a conventional manner. In the opposite direction, i. for the signal flow from the door frame to the door, either the same, in this case bidirectionally operating signal converter or a second converter pair can be used. If appropriate, this signal return flow can be conducted via a second line, for example a two-wire line of the connecting cable. Depending on the type of signal transmission between the two signal converters, e.g. Signal bus with bus protocol, frequency division multiplexing, digital pulse or pulse packet transmission, transponder operation or according to another transmission method, as well as depending on the type of signal line, e.g. Wire or fiber, the type of signal converter and the number of signal lines is selected.

In the course of the ever-advancing technology of the monitoring and measuring units, there is a desire to monitor and process more and more information and thus also to transmit it to a central evaluation unit. This can lead to the transmission capacities of the connection cable or even the signal converter reaching their limits and signals being only delayed or incorrectly transmitted. On top of that comes the nature of the transfer Data or even the safety regulations for a data transfer via a cable transition always change, which is why it was previously necessary to replace the cable transitions or complex to adapt to the new requirements or to reset.

The invention is therefore an object of the invention to provide a cable transition of the type mentioned above, while maintaining the above advantages particularly easy to process and transmit larger incoming data or signal information and can be easily adapted to changing amounts of data, data types and security specifications ,

This object is achieved according to the invention in that at least one signal processing unit comprises at least one connecting element for signal-side connection of the processor unit and / or the signal converter to a processor unit and / or a signal converter of a third signal processing unit.

Advantageous embodiments of the invention are the subject of the dependent claims.

The invention is based on the consideration that an extension of the incoming signal lines to the signal processing unit, should not take place via an extension of the incoming data cable for an increase in the incoming data capacity, so that the existing system on the one hand remains as compact as possible and on the other hand, not even with later extension must be replaced. It was therefore recognized that such an increase in the data volume is possible even under these conditions, if the system is individually expandable in terms of a modular design and the claims. The signal processing units therefore comprise a connection element, for example in the form of a connection, for the signal-side connection of a further signal processing unit. Thus, several signal processing units can be spatially separated from each other and the signals transmitted via a single cable transition. It is particularly advantageous if these other signal processing units also include signal converter, so that the signals between the two modular connected Signal processing units, as already at the cable transition, also can run on a few core cable.

For the hierarchical management of access to the existing lines and signal converter while a master-slave architecture can be applied, wherein a processor unit or a signal processing unit is the master and controls the data transfer. For the coordination of data transmission, a fieldbus system (for example, LIN bus) can be used.

It is thus possible to arrange signal processing units directly in locks, door drives, fingerprint systems or sensor systems, for example temperature, light and / or vibration sensors, and to connect them to a signal processing unit of a cable transition.

For a particularly simple transmission of the data and configuration of the system, in a preferred embodiment, at least part of the signal processing units each comprise a transmitting and receiving unit. This transmitting and receiving unit can be part of the connecting element, so that signals can be transmitted from a signal processing unit to a second signal processing unit, but it can also be designed to receive control or system data.

To relieve the data volume, which is transmitted via the flexible cable transition, therefore, the transmitting and receiving units are designed in a preferred embodiment to transmit measurement, monitoring and / or control of a signal processing unit to the other signal processing unit.

For the distribution, control and merging of the data, each signal processing unit in a preferred embodiment comprises a processor unit. This processor unit is designed according to corresponding stored or learned rules and criteria to distribute the signals arriving from the plurality of signal lines to the signal converter or the transmitting and receiving unit and, accordingly, from the signal converters or the transmitting and receiving unit to pass incoming signals to the multiple signal lines. For this purpose, the processor unit can, for example, distribute the incoming signals to the signal converters for a wired transmission or to the transmitter and receiver units for wireless transmission, depending on their type, relevance or security requirement. In addition, the processor unit may send configuration signals or commands to the signal transducers or the transceiver to configure or program them accordingly.

For a particularly simple external configuration or programming of the components of the signal processing unit, the transmitting and receiving unit is designed in an advantageous embodiment to receive corresponding control signals and forward them to the processor unit for configuration or programming of the components of the signal processing unit. This makes it possible to adjust and also to adapt the processing, distribution and transmission of the signals via an external terminal, for example via a program executed there.

In order to meet high security standards in the wireless transmission of signals between the transmitting and receiving units, the data is preferably transmitted encrypted. Depending on the wireless transmission type used, such as Bluetooth, WLAN, or other transmissions in the radio frequency range, infrared or optical frequency range, appropriate encryption techniques are used. By using a modular design, the radio links to be transmitted are usually low, so that a near-field communication, for example in the form of RFID technology is possible. In addition, the transmitting and receiving units can be operated with low power, which is in terms of regulatory requirements in the approval and safety aspects of advantage.

In order to enable a particularly simple monitoring of the signals and the mode of operation of the cable transition, in an advantageous embodiment at least one transmitting and receiving unit is designed to communicate with another network. Another network can for example the home network or another local area network. For a simple communication with the further network, the transmitting and receiving unit is preferably in an IP address range with the other terminals of the other network.

In order to be able to provide the simplest possible, compact and exchangeable cable transition, in a preferred embodiment at least one signal processing unit is arranged in a plug part. With a corresponding associated plug part at the end of the incoming or outgoing signal lines thus a detachable plug connection can be achieved. In alternative or mixed construction, at least one signal processing unit can also be arranged in a line or a cable. In this case, the signal processing unit is protected in a preferred embodiment, for example by means of a heat shrink tubing or filled with a mass envelope from external access or loads.

The provision of the power supply can be transmitted via a conventional transmission type wired or wirelessly. Furthermore, long-lasting energy storage media, an energy-recovering power supply or even an independent generation of a supply voltage can be provided. Such a power supply ensures the network capability of the individual components. The power supply can also be done via the connection cable.

For a particularly simple monitoring of the operating states of the signal processing units, these include in a preferred embodiment a visual display and / or an acoustic signal generator, which signal the readiness for operation.

The advantages achieved by the invention are in particular that by the use of transmitting and receiving units in the simplest way, a programming of the signal processing units, a query and transmission the signals and a coupling of the signal processing units in other networks is made possible.

Thereby, measurement or observation signals can be retrieved from the terminal 26 or the network 28. It is also possible to send corresponding control signals via this connection to the transmitting and receiving units 16, 20 in order to make adjustments to the measuring or observation devices in response to the measuring or observation signals or also the signal processing units 2, 4 or the signal converter 14, 18 or reprogram or configure the processor units 12, 22. For this purpose, the received control signals from the corresponding transmitting and receiving unit 16, 20 are sent to the respective processor unit 12, 22 and evaluated or processed by the latter.
