A first aspect of the invention relates to a signal transmission device for a device, in particular for a caravan, caravan, motor caravan or a boat. The signal transmission device comprises a transmitting and receiving unit, preferably without display or without screen. In other words, it is preferably provided that the transmitting and receiving unit, in particular the signal transmission device as a whole, has no display, so that the transmitting and receiving unit, in particular the signal transmission device, is free from a display or a screen.

The transmitting and receiving unit has at least one receiving element which is designed to receive received data which characterize or describe at least one state of at least one part, in particular at least one component, of the device. The transmitting and receiving unit further comprises at least one transmitting element, which is designed by radio technology, that means by radio at least a local wireless data connection with at least one mobile device such as a mobile phone, a smartphone, a tablet PC, a notebook or set up the same mobile terminal and transmit data resulting from the received data, which characterize the at least one state or describe wirelessly via the wireless data connection to the mobile terminal to transmit. For example, the data connection is a Bluetooth connection or a Wi-Fi connection, so the wireless data connection, for example, via Bluetooth, WLAN or by means of another standard or another technique for establishing local wireless data connections is established.

Since the transmitting and receiving unit is preferably free from a display and thus has no display, the transmitting and receiving unit can be designed, for example, as a module, in particular as a space-saving module and, for example, in an existing system such as, in particular, a CI bus (for example). Caravanning industry bus). Since the transmitting and receiving unit is formed, for example, as an independent or coherent or assembled module, for example, the receiving element and the transmitting element are integrated in a common housing, that is accommodated in said housing.

Background of the invention is that devices such as caravans, caravans, motor caravans or boats usually a variety of electrical, especially electronic, components such as temperature, level or battery sensors, power supplies, chargers, batteries, refrigerators, satellite systems, jacks, maneuvering, Suspension components, entertainment systems, fuel cells, heating, air conditioning and photovoltaic systems exhibit. These components are interconnected to an increasing extent, in particular via at least one data bus such as the aforementioned CI bus, and can exchange information via the data bus.

Via the data bus, which is also simply referred to as a bus, the components can, for example, send status, operating and control information, that is, transmit it to the respective other components and receive it, in particular from the respective other components. Typically, the components are connected to the data bus and thus via the data bus with each other, so that the components via physical, ie physically existing cables or cables to the data bus and thus with each other, in particular signal technology, are connected.

By means of the signal transmission device according to the invention, it is now possible to at least one of the transmission data characterizing the above-mentioned state to transmit mobile terminal and thus for example to the mobile terminal, in particular on a terminal display of the mobile terminal to display the transmission data or from the transmission data resulting and the at least one state characterizing numbers and / or letters and / or symbols or graphics. As a result, for example, a person using the mobile terminal device can be communicated with the at least one status, in particular optically. In particular, it is possible to transmit respective states of the respective, previously mentioned components to the mobile terminal using the transmission data characterizing the respective states and to display them on the terminal display so that the aforementioned person can quickly and easily obtain an overview of respective states of the components. In particular, it is thus possible to display all information such as status and operating information about the device, in particular about the said components, on the mobile terminal. Since the transmission data is transmitted wirelessly, that is to say without the use of a physically present cable from the transmitting and receiving unit to the mobile terminal, in particular directly, the person does not have to physically connect the mobile terminal to the device or to said data bus Connect cable. As a result, the person can retrieve and receive the aforementioned information particularly easily and conveniently.

In one embodiment of the invention, the signal transmission device comprises at least one in addition to the transmitting and receiving unit provided and external to the transmitting and receiving unit display, which is also referred to as a screen, the display for displaying the at least one state characterizing numbers and / or Letters and / or symbols or graphics is formed.

The display is, for example, part of a fixed to, in particular, installed in the example designed as a vehicle device or built-in central unit, which is connected via at least one physical cable to the data bus and thus to the components. In particular, the central unit is firmly connected via supply and control lines in the designated also as a bus system data bus. The central unit usually functions here as, in particular signal technical, master of the data bus, the remaining components function as respective slaves of the data bus.

In principle, it is conceivable that the transmitting and receiving unit is integrated in the central unit or in the display, so that, for example, the transmitting and receiving unit with the display forms an assembled or contiguous structural unit or a module, in particular in the form of the central unit.

Preferably, however, it is now provided that the transmitting and receiving unit is externally formed in addition to the display with respect to the display, so that, for example, the display and the transmitting and receiving unit are different and in particular separate or external units or modules. In this way, it is for example possible to integrate the transmitting and receiving unit in a particularly simple manner in an already existing and, for example, a display or a central unit as a master and at least one further component as a slave comprehensive bus system, thereby the bus system which is not actually designed to wirelessly provide said information to a mobile terminal, to enable it to provide the information, that is, the at least one state of the device based on the transmission data via the wireless data connection to at least one mobile device. In this way, the transmitting and receiving unit can be offered and installed in particular as a subsequent additional solution, which is also referred to as an add-on solution. In particular, this makes it possible to extend already existing data buses or bus systems to the functionality to be able to transmit information about at least part of the device wirelessly and to at least one mobile terminal.

A second aspect of the invention relates to a signal transmission device for a device, in particular for a caravan, caravan, motor caravan or a boat. The signal transmission device according to the second aspect of the invention comprises a transmitting and receiving unit which has at least one receiving element. The receiving element is configured to receive receive data characterizing at least one state of at least a portion of the device. In addition, the transmitting and receiving unit has at least one transmitting element, which is designed to set up at least one local wireless data connection with at least one mobile terminal using radio technology, and from the receiving data resulting transmission data, which characterize the at least one state, via the data connection wirelessly to the to transmit mobile terminal. The preceding and following embodiments of the first aspect of the invention, that is to say the signal transmission device of the first aspect of the invention, are readily applicable to the second aspect of the invention, that is to the signal transmission device according to the second aspect of the invention, and vice versa. By the feature that the transmission data results from the reception data, it is to be understood in particular that the transmission data is obtained from the reception data. Furthermore, it is possible for the transmission data to correspond to the reception data.

In the second aspect of the invention, the signal transmission device further comprises at least one additional to the transmitting and receiving unit provided and with respect to the transmitting and receiving unit external display for displaying the at least one state characterizing numbers and / or letters and / or symbols. The respective display is, for example, an electronic display or an electronic screen.

By means of the signal transmission device according to the second aspect of the invention, it is possible to display the numbers and / or letters and / or symbols or graphics, that is, in particular optical information about the state on the display, which is permanently installed, for example in the device. Furthermore, it is possible to display the information about the state on the mobile terminal and in particular on a particular electronic terminal display of the mobile terminal, so that a person can obtain information about the state of the device in a particularly simple manner.

In a particularly advantageous embodiment of the invention, the transmitting and receiving unit has at least one connection device, by means of which the transmitting and receiving unit can be connected by means of at least one physical line to a data bus of the device designed, for example, as a CI bus or is connected. As a result, the received data can be transmitted to the transmitting and receiving unit in a particularly advantageous manner.

It has been found to be particularly advantageous if the transmitting and receiving unit is designed as a module and to signal via the connection device in the data bus of the device between a per se designed as a master of the data bus first component and at least one per se as a slave the data bus formed second component of the device to be arranged. Furthermore, the transmitting and receiving unit is configured to signalically suggest to the master that the transmitting and receiving unit is the slave. Furthermore, the transmitting and receiving unit is preferably designed to signalically suggest to the slave that the transmitting and receiving unit is the master. In this way, the transmitting and receiving unit can be integrated into the data bus and thereby physically between the master and the slave, without this being recognized by the master or the slave. For example, if the slave communicates with the transmitting and receiving unit, the slave assumes that the transmitting and receiving unit is the master, so that the slave assumes that it is communicating with the master. If, for example, the master communicates with the transmitting and receiving unit, the master assumes that the transmitting and receiving unit is the slave. Thus, the master actually assumes that he is communicating with the slave. In this way, the transmitting and receiving unit can be integrated in a particularly simple manner in the data bus, in particular subsequently. In other words, the transmitting and receiving unit can be integrated in a particularly simple manner into the already existing data bus and in particular physically between the master and the slave. Thus, it is possible to extend existing data buses to the transmitting and receiving unit, so that the information about the state can be provided wirelessly by means of the transmitting and receiving unit.

In this case, it is provided, for example, that in particular as the said central unit formed first component has the said display.

The transmitting and receiving unit can be formed unidirectionally, so that the transmitting and receiving unit is for example only designed to transmit the transmission data to the mobile terminal.

However, it has proven particularly advantageous if the transmitting and receiving unit is bidirectional. In this case, the transmitting and receiving unit is preferably designed to receive data provided by the mobile terminal via the data connection via the data connection and thus wirelessly. As a result, particularly advantageous functions can be displayed in a simple manner.

In order to provide a particularly advantageous functionality, it is provided in an advantageous embodiment of the invention that the signal transmission device is adapted to effect at least one function of the device depending on the received data. In this way, for example, the aforementioned person can make entries in the mobile terminal, resulting from these inputs, the above, provided by the mobile device data. The data provided by the mobile terminal are, for example, control or regulation information resulting from the inputs, by means of which the said function of the device is effected. Thus, for example, it is possible for the person to effect the function via the mobile terminal.

In order to display the information on the mobile terminal and / or to receive the inputs of the person in the mobile terminal and to provide the control information in the sequence, for example, a particularly portable software is provided, which on the mobile terminal, in particular by means of a computing device of the mobile terminal. The software is also referred to as an application or app and provides, for example, a graphical user interface, via which the person can execute the mentioned inputs and / or can visually perceive the letters or numbers or graphics which illustrate the state.

In the case of the signal transmission device according to the invention, it is provided in particular that the described local data connection and, for example, a in particular to use direct wireless communication to the mobile terminal and the transmitting and receiving unit, so that the transmission data from the transmitting and receiving unit to the mobile terminal, bypassing a mobile network and bypassing Internet-based services can be transmitted. It has been found that when using a mobile network and / or Internet-based services to transmit information, for example, from the device to a mobile terminal, costs for the use of mobile networks may arise. Furthermore, communication between the device and a mobile terminal via mobile radio or via Internet-based services in areas without or with poor network coverage or mobile network coverage is not possible. These problems and disadvantages can now be avoided by means of the signal transmission device according to the invention.

Finally, it has proven to be particularly advantageous if the state is a level of a water tank of the device and / or a level of a gas tank of the device and / or an amount stored in an energy storage device of the device electrical energy and / or a temperature and / or a State of at least one light source of the device and / or a state of an alarm system of the device and / or a state of an air conditioner of the device and / or a state of heating the device and / or a current location of the device. In this way, the mobile terminal and thus the person using the mobile terminal can be easily supplied with extensive information about the device without having to connect the mobile terminal with a physical cable to the device.

The transmitting and receiving unit, in particular the signal transmission device, for example, housed in a housing which can be mounted on, in particular, the device. The signal transmission device, in particular the transmitting and receiving unit, has, for example, a wired Bussowie power supply interface, which can be connected to the transmitting and receiving unit with said data bus and to a voltage source via at least one physical cable. The connection of the signal transmission device or the transmitting and receiving unit The data bus and the voltage source, also referred to as a voltage supply, take place in particular via standardized plug contacts, in particular the said bus and power supply interface.

It is conceivable that the signal transmission device additionally has a wired communication device for transmitting information. Thus, for example, information can be transmitted and at the same time an energy storage designed, for example, as a battery for storing electrical energy of the mobile terminal can be charged. In other words, it is conceivable that the signal transmission device can be connected via the wired communication device by means of a physical cable to the mobile terminal or connected, so that the aforementioned information not or not only via the wireless data connection, but via the physical cable and thus can be transmitted via the communication device to the mobile terminal. Furthermore, for example, electrical energy can be transmitted from the signal transmission device to the mobile terminal via the communication device and thus via the physical cable, so that the energy store of the mobile terminal can be charged with the transmitted electrical energy.

In a further advantageous embodiment, the signal transmission device includes at least a part of display or control functions usually realized via the permanently installed central unit. In this case, the signal transmission device is easily accessible and visibly installed in the example designed as a vehicle device. This also has an advantageous effect on the radio range of the transmitting and receiving unit. The signal transmission device is, for example, part of the bus system or integrated into it and communicates with the other bus components via a defined bus protocol corresponding to the respective bus standard. For this purpose, the signal transmission device includes, for example, a data processing unit with corresponding software.

Furthermore, it is conceivable that the transmitting and receiving unit, in particular the signal transmission device, is integrated as master or slave in the data bus. particularly advantageous is the integration of the signal transmission device, in particular the transmitting and receiving unit, in the bus as the master, since in this case the original central unit can be omitted and replaced by the signal transmission device. This can save costs.

As described above, it has proven to be particularly advantageous if the signal transmission device or the transmitting and receiving unit is connected directly between the central unit and the remaining bus components. If, for example, the transmitting and receiving unit is designed to be unidirectional, for example, the portable software on the mobile terminal serves exclusively to display the aforementioned information and, for example, as status, operating and functional information.

In a further embodiment, the signal transmission device and the mobile terminal may include software that transmits, in particular, information relating to service, maintenance and software versions of at least individual bus components by means of wireless bidirectional communication and makes it possible to update the software and to change software parameters of at least individual bus components. The signal transmission device offers the user and in the case of service a higher overall and better useable functionality of the data bus including all embedded in the data bus electrical and electronic devices and can also allow for the elimination of the original central unit significant cost and weight savings.

In the figures, the same or functionally identical elements are provided with the same reference numerals.

Fig. 1 shows a schematic plan view of a signal transmission device 10 for a device such as a caravan, a caravan, a motor caravan or a boat. The signal transmission device 10 comprises a transmitting and receiving unit 12, which is designed, for example, as an independent, that is, connected or assembled module. The transmitting and receiving unit 12 has a Fig. 1 particularly schematically illustrated receiving element 14, which is adapted to received data to receive the at least one state of at least one part, in particular at least one device, the device to receive.

The signal transmission device 10 also has at least one in Fig. 1 particularly schematically illustrated transmitting element 16, which is adapted to at least one local wireless data connection 18 with at least one radio technology Fig. 2 to 4 recognizable and designed, for example, as a smartphone or mobile phone terminal 20 to build and from the received data resulting transmission data, which characterize the at least one state, via the data link 18 wirelessly to the mobile terminal 20 to transmit.

Out Fig. 1 is particularly well recognized that the transmitting and receiving unit 12, in particular the signal transmission device 10 in total, no display, that is, has no electronic display and is thus free of an electronic display. The transmitting and receiving unit 12, in particular the signal transmission device 10, is thus an indicator-free or a display-free module element, which thus can be incorporated, for example, in a simple and space-saving manner in a designated also as a bus system data bus of the device. The aforementioned components of the device are, for example, electrical or electronic components which, in particular by means of at least one physical cable in each case, are connected to the said data bus and thus to one another. The components can transmit or in particular exchange signals or data via the data bus. In this case, for example, a central unit is provided, which is connected via at least one physical cable to the data bus and thus via the data bus with said components. Thus, the components and the central unit can transmit data or signals via the data bus and especially exchange. The central unit is for example a first component of the data bus, while the components are respective second components of the data bus. In this case, for example, the central unit itself is a master of the data bus, while, for example, the respective component or the respective second component per se is a slave of the data bus. In this case, it is possible in particular to integrate the transmitting and receiving unit 12, in particular the signal transmission device 10, in particular physically, between the master and the respective slave into the data bus. The data bus is designed, for example, as a CI bus (caravan industry bus).

In order to be able to integrate the signal transmission device 10 in the data bus in a particularly simple manner, in particular between the central unit and the respective second component, the transmitting and receiving unit 12 has at least one connection device 22 with at least one line 24, so that the transmitting and receiving unit 12 via the connection device 22 can be connected or connected to the data bus by means of the physical line 24. For this purpose, for example, the line 24, in particular standardized, plug contacts 26, via which the line 24 can be easily connected to the data bus. In this way, the transmitting and receiving unit 12 can exchange data with the central processing unit and the second components. In particular, it is possible, for example, for the components to transmit the said received data characterizing respective states of the respective components via the data bus and via the line 24, ie via the connection device 22 to the transmitting and receiving unit 12, which receives the received data.

From the received data, the said transmission data are generated, which are wirelessly transmitted via the wireless data connection 18 to the mobile terminal 20 and received by the mobile terminal 20. In this case, for example, the signal transmission device 10 and the mobile terminal 20 are part of a system.

Out Fig. 2 to 4 It can be seen that the mobile terminal 20 has an electronic screen, referred to as a terminal display 28, which is designed to write letters in dependence on the received transmission data and / or symbols and / or numbers characterizing the respective states of the respective second components (devices). For this purpose, for example, runs on the mobile terminal 20, also referred to as an app or application software, which is executed by means of a computing device, in particular by means of an electronic computing device, the mobile terminal 20. The software has a graphical user interface 30, which is displayed on the terminal display 28.

A first of the components is, for example, a water tank for receiving fresh water, so that a first of the states is a level of the water in the water tank. This fill level is displayed, for example, in a first area 32 of the graphical user interface 30 and thus the terminal display 28. As a result, the person using the mobile terminal 20 is visually communicated the level.

A second of the components is, for example, a navigation system for determining a current position of the device on the earth. Thus, for example, a second of the states is the current position of the device on earth determined by the navigation system. In this case, for example, the current position of the device and a prevailing at the current position outside temperature in a second area 34 of the graphical user interface 30 are displayed.

A third of the components is, for example, an energy accumulator designed in particular as a battery for storing electrical energy. In this case, for example, a third of the states is a voltage and / or an amount of electrical energy stored in the energy store, wherein the third state is displayed, for example, in a third area 36 of the graphical user interface 30. In particular, an electrical voltage of the energy store is displayed in the third area 36.

In a fourth area 38 of the user interface 30, for example, the amount of electrical energy stored in the energy store is displayed. Further, it is conceivable that the area 38 is an operating element, which can be operated or actuated by the person in particular by the person that the Touched terminal display 28 in the area 38. By touching the area 38, for example, the amount of electrical energy stored in the energy store is displayed.

A fourth of the components is for example a temperature sensor for detecting at least one temperature of the device and / or the ambient temperature. In this case, for example, the temperature detected by means of the temperature sensor is displayed in a fifth region 40 of the user interface 30, or the region 40 is another operating element which can be operated or actuated by the person. The person can actuate or operate the further operating element in particular by the person touching the terminal display 28 in the area 40. By actuating or operating the further operating element, for example, the detected temperature is displayed, in particular on the terminal display 28. The areas 32, 34, 36, 38 and 40 form for example a first side S1 of the user interface 30 or are components of the first side S1.

In Fig. 3 For example, a second page S2 of the user interface 30 is illustrated. The second side S2 comprises, for example, regions 42 and 44, wherein, for example, the region 42 corresponds to the region 40 with respect to its information content and / or function, and wherein, for example, the region 44, in particular with regard to its function and / or its information content, for example the region 38 equivalent. In addition, the second side S2 comprises further regions 46, 48, 50 and 52. The regions 46, 48, 50 and 52 are, for example, in particular virtual, operating elements which can be operated by the person that the person displays the terminal 28 in the respective area 46, 48, 50 and 52 touched. Thus, the previous and following remarks on areas 40 and 38, and 42 and 44, respectively, may be applied to areas 46, 48, 50, and 52, and vice versa.

For example, by operating, in particular clicking, the area 46 receives the person information about stored in the device water. By operating the area 48, for example, the person receives information about at least one Light source, in particular via a plurality of light sources, the device. For example, by operating or actuating the area 50, the person receives information about an alarm system of the device, for example. Further, the person receives, for example, by operating or operating the area 52 information about a gas system of the device and thus for example via a gas tank for storing gas.

Finally shows Fig. 4 a third page S3 of the user interface 30. The third page S3 is displayed, for example, when the person operates or touches the area 42, in particular clicks. The third side S3 has an area 54 which, for example, shows a set temperature of an air conditioner of the apparatus. A region 56 shows, for example, a temperature which is also referred to as the inside temperature and prevails in the interior of the device, while, for example, a region 58 shows a desired temperature set by the person, for example, which should prevail in the interior. Furthermore, the third side S3 comprises further regions 60, 62, 64 and 66. The regions 60, 62, 64 and 66 are, for example, control elements. Alternatively or additionally, the areas 54, 56 and 58 may be control elements. For example, by operating the area 54, for example, the person can set the air conditioner. For example, by operating the area 56, the person may obtain, for example, more information about the inside temperature. For example, by operating the area 58, the person can set the desired temperature. By actuating the area 60, the person receives, for example, information about a heating of the device. By actuating the area 62, the person receives information about the air conditioning system, for example. By actuating the area 64, the person receives, for example, information about a frost warning. By actuating the region 66, for example, the person can de-ice at least one part, in particular at least one pane, of the device.

Thus, it is conceivable that the transmitting and receiving unit 12 is formed as a bidirectional transmitting and receiving unit. This means that the transmitting and receiving unit 12 can transmit not only the said transmission data via the data link 18 to the mobile terminal 20, but the transmitting and receiving unit 12, for example via the wireless data link 18 from the mobile Terminal 20 wirelessly receive data provided via the wireless data connection 18. The data mentioned are, for example, control or regulating data, by means of which the signal transmission device 10 can, for example, effect at least one function of the device, in particular of at least one of the components of the device. In this way, for example, the person can use at least one of the components of the device as needed via the mobile terminal 20 and in particular via the user interface 30.

Overall, it can be seen that the person is supplied with information about the device and can operate the device, in particular via the mobile terminal 20 and thus without having to connect the mobile terminal 20 via a physical line with the device. As a result, the device can be operated particularly easily and the person can obtain information about the device in a particularly simple manner.

The FIGS. 5a and 5b show in schematic representations the various possibilities of integration of the signal transmission device, in particular the transmitting and receiving unit 12 in the data bus 68. It shows the Fig. 5a the integration of the transmitting and receiving unit 12 in the data bus 68, wherein the reference numeral 70 of the master and the reference numerals 72, 74, the slaves of the data bus 68 are outlined. Furthermore, it is shown that the transmitting and receiving unit 12 suggests to the master 70 that it is a slave S. In contrast to the slaves 72, 74, the transmitting and receiving unit 12, on the other hand, suggests that it is the master M. In Fig. 5b the transmitting and receiving unit 12 represents the master of the data bus 68.
