    description
    METHOD FOR OPERATING DEVICES IN A LIGHTING SYSTEM The present invention relates to a method for operating devices in a lighting system which has a so-called DALI bus. Furthermore, the present invention relates to a so-called splitter unit for use in a DALI system and a lighting system with a DALI bus and a corresponding splitter unit.
    To control lights of a more complex lighting system, the so-called DALI (Digital Addressable Lighting Interface) standard has been established in the past. It is a communication protocol for digital control, in particular of operating devices for light sources, which enables multiple devices to be transmitted either in groups or individually to B. adjust or dim the light sources within a certain brightness range. This DALI standard not only enables digital control of the devices, but also allows lamp control units to send feedback on the operating status to a central control unit, which enables defects in individual devices to be determined very easily and quickly. Furthermore, other devices such as. B. sensors or the like can be integrated into the system.
    [0003] A lighting system based on the DALI standard usually has a bus line, the so-called DALI bus, to which all devices are connected.
    This DALI bus is a data line separate from the general power supply, via which commands are transmitted to the devices.
    In order to be able to use the DALI functionality, the control unit of the system must know in what way it can contact the consumer, in particular the lights or their operating devices, individually. For this purpose, it is provided that a so-called operating address is assigned to each luminaire, the operating address then generally being part of the DALI command issued by the control unit during later operation. Only so-called broadcast commands, which are directed to all participants in the system, do not contain any individual address information. In the DALI standard, a maximum of 64 addresses can be assigned within a bus system.
    So that the individual luminaires receive an operating address and the control unit also knows under which operating address the respective luminaire can be contacted, a systematic address assignment must take place as part of an initialization of the system. For this purpose, different variants of a commissioning process are known from the prior art, with almost all variants having in common that the lights initially have an individual address of origin, for example, assigned during manufacture, under which they can identify. After these addresses of origin have been communicated to the central control unit, the latter successively prompts the individual lights to identify themselves, which is usually done by a predetermined way of emitting light. This means that the associated luminaire switches on or flashes, for example. A user of the system must then determine at which point within a room and / or a building the corresponding luminaire is positioned and communicate this information to the control unit. This then transmits an operating address with the aid of the original address of the luminaire that is currently being identified and can then control the luminaire at this operating address during later operation. This process is repeated until an address has been assigned to all lights.
    Obviously, the previously described method is time-consuming, since it is not foreseeable which luminaire will identify itself next, and accordingly it can take quite some time until the luminaire that is just being identified is discovered.
    The present invention is therefore based on the task, an alternati1 / 8

    To offer a patent office solution with which the effort for commissioning a DALI system can be reduced, at least in special situations, but in spite of everything there is the possibility to control the lights in the known way with the help of DALI commands.
    The object is achieved by a so-called splitter unit with the features of claim 1 and by a method according to claim 8. Advantageous developments of the invention are the subject of the dependent claims.
    According to the present invention, a new type of device used in a DALI system is proposed. This device, referred to as a splitter unit, has an input connection for connection to a DALI bus and at least two output connections. As is customary with DALI devices, the device according to the invention is capable of receiving the signals on the input side, that is to say via the DALI bus. These DALI commands are then selectively forwarded to the connections on the output side, depending on the address information assigned to the received DALI command and now in the form of broadcast commands. Then consumers, generally luminaires, are connected to the output-side connections of the splitter unit according to the invention, which receive these broadcast commands and immediately implement them.
    According to the invention, therefore, a splitter unit for use in a lighting system is proposed, which has an input-side connection for connection to a DALI bus and at least two output-side connections, the splitter unit being designed to receive via the input-side connection Assign DALI commands depending on the address information assigned to the received DALI command to the output connections and issue the corresponding DALI command as a broadcast command via the corresponding output connection.
    Furthermore, a method for operating devices in a lighting system having a DALI bus is proposed, the devices being designed to communicate in accordance with the DALI standard, and in a splitter connected to the DALI bus Unit DALI commands received are assigned to an output-side connection of the splitter unit depending on the address information assigned to the receiving DALI command and are output as a broadcast command via the corresponding output-side connection to the devices connected to it.
    Preferably, the splitter unit is designed to assign exactly one DALI address to each output-side connection. In the event that broadcast commands are received via the input connection, the splitter unit is preferably designed to issue this broadcast command to all connections on the output side.
    The splitter unit also occupies addresses of the DALI system to which the splitter unit is connected with its input connection. According to the invention, however, the splitter unit now takes over the function of deciding whether the address information assigned to the DALI command is relevant - that is to say it is intended for at least one of the output connections - and then forwards the command in a corresponding manner to the output connection. The forwarding now takes place as mentioned above as a broadcast command, i.e. without individual address information. The consumers connected to the corresponding output-side connection are thus operated in the same way, with the advantage that none of these consumers has to be assigned an individual operating address. This means that it is only necessary to connect the consumer (s) to the suitable output connection of the splitter unit according to the invention, however, further measures such as the assignment of a specific operating address are no longer necessary.
    As a result, the effort involved in commissioning a DALI system can be significantly reduced, this advantage having an effect particularly when consumers are arranged in recurring patterns or configurations and should accordingly be provided with operating addresses in a correspondingly systematic manner. This situation 2/8

    Patent office on is available, for example, in hotels in which the corresponding lights are more or less always arranged in the same way in similarly designed hotel rooms. Even in hospitals or similar facilities there is a recurring arrangement of the lights, so that the use of the splitter unit according to the invention also has special advantages.
    The measures described so far concerned in particular the forwarding of DALI commands by the splitter unit to the consumers. In the same way, however, according to an advantageous further development, feedback can also take place, for which purpose the splitter unit is designed to forward DALI feedback arriving at an output-side connection to the DALI system via the input-side connection and in this case the forwarded feedback with the corresponding DALI address assigned to the output connection.
    As already mentioned, the splitter unit according to the invention thus occupies several DALI addresses of a DALI system connected to the input-side connection. It is preferably provided here that means are provided on the splitter unit itself, with the aid of which it is optionally possible to determine which DALI addresses are to be used. In particular, a manual setting of a start address can be provided, this start address being assigned to the first connection on the output side and the splitter unit logically assigning corresponding successive DALI addresses to the further connections on the output side. Ultimately, all that is required to start up the system is simply assign a desired DALI start address to the splitter unit and the lights must be connected to the corresponding output connections on the splitter unit. In comparison of an individual assignment of operating addresses to all individual lights, this represents a significant reduction in the amount of work.
    The invention will be explained in more detail with reference to the accompanying drawings. Show it:
    Figure 1 [0020] Figure 2 [0021] Figure 3 is a schematic representation of a DALI system in which several splitter units according to the invention are used;
    the functioning of the splitter unit according to the invention when forwarding DALI commands and the forwarding of feedback by the splitter unit according to the invention.
    Figure 1 first shows the structure of a lighting system according to the invention, generally provided with the reference numeral 1, communication being provided in accordance with the DALI standard. A central component of system 1 is a bus line 2, the so-called DALI bus, to which the various participants in system 1 are connected. The lines for the power supply of the various participants in the system 1 are not shown in the present exemplary embodiment, since the type of power supply does not play a role for the inventive concept. In the present case, the lines shown are used exclusively for communication between the various devices.
    The DALI standard is based on the so-called master-slave principle, i. That is, a unit of the system 1 is authorized to issue control commands on the bus line 2 on its own in order to contact and control the various participants and to query any feedback. In the present case, it is a so-called DALI controller 100, that is to say a central control unit which gives control commands to the bus line 2. These are then transmitted to the various devices that are connected to bus line 2. These devices can be a wide variety of devices, provided they are able to communicate in accordance with the DALI standard. For the present case, it is assumed that these devices are electronic ballasts or, in general, operating devices for operating light sources. So these devices are in

    Integrated luminaires and designed to implement received DALI commands in such a way that the brightness of the light sources is adjusted accordingly. It would also be conceivable to connect sensors via which the lights can be controlled automatically. These can be brightness or presence sensors. The signals made available by these sensors are queried by the central control unit 100 and then converted into corresponding commands for controlling the operating devices.
    It should also be pointed out that the lighting system 1 according to the invention could of course be expanded such that the central control unit 100 again receives information on the lighting control from a higher-level position. This is shown schematically in FIG. 1 by a further unit 200, which communicates with the control unit 100. Here, however, it is not necessary that the communication takes place according to the DALI standard. Instead, any type of communication between two intelligent devices could be used.
    In the present case, the consumers, that is, the lights 20 or their operating devices are not directly connected to the DALI bus 2. Instead, as can be seen, a splitter unit 10 according to the invention is interposed. In the exemplary embodiment shown, two splitter units 10 are provided, which are connected directly to the DALI bus 2 and are each connected on the output side to a group of consumers 20. As will be described in more detail below, there is an advantage in particular if the consumers connected to the splitter units 10 are configured in the same way, which can be the case, for example, if a splitter unit with the associated subsequent consumers are each assigned to a room and there are several similar rooms within a building. Such a situation exists, for example, in hotels or hospitals.
    For the present exemplary embodiment, it is therefore assumed that the two splitter units 10 shown are each in different rooms, but are connected to the central control unit via the central DALI bus 2. The functioning of the splitter units 10 is - apart from the DALI address range which they occupy - identical, which is why the design and function of the first splitter unit 10 or left in the illustration is to be explained in more detail below.
    As can be seen, the splitter unit 10 initially has an input-side connection 11, via which the connection to the DALI bus 2 is established. The splitter unit 10 is thus able to communicate via the DALI bus 2 and in particular to receive DALI commands or to transmit feedback messages to the control unit 100 in accordance with the DALI standard. On the output side, on the other hand, the splitter unit 10 has a plurality of output connections 12, ten in the exemplary embodiment shown, to which in turn a further line 15 is connected for command transmission, which ultimately leads to the lights 20 to be controlled. Communication also takes place via these lines 15 in accordance with the DALI standard, since the lights 20 represent DALI devices as described above. This means that each output-side connection of the splitter unit 10 is in turn connected to a now very small DALI bus. Of course, the number of connections on the output side can also differ from the variant shown.
    A special feature is that communication via these subordinate DALI buses, ie lines 15, is to be carried out exclusively with the aid of broadcast commands. This means that the lights 20, which are connected on the output side to a splitter unit 10, do not have to be assigned an individual operating address and all the lights 20 connected to a specific output-side connection 12 are operated in a similar manner. However, it is not absolutely necessary for several lights to be connected to a single output connection 12. It may well be provided that only a single lamp is connected to an output connection 12. In this case, too, there are advantages, as described in more detail below
    AT16 348U1 2019-07-15 Austrian
    Patent office lent the effort involved in commissioning system 1.
    Although all lights 20, which are connected to outputs of the splitter units 10, are to be controlled using broadcast commands, these connections 12 occupy addresses of the DALI system 1 in spite of everything. Strictly speaking, each splitter unit 10 an address range, which corresponds to the number of connections 12 on the output side. In the exemplary embodiment shown, in which splitter units 10 each have ten connections 12 on the output side, this means that each splitter unit 10 uses ten different DALI operating addresses, it being assumed in the present case that the DALI start address of the the first splitter unit 10 is "10", that is, the addresses "10" to "19" of the DALI system 1 are used, while the DALI start address of the second splitter unit 10 is "20" and this unit accordingly has the addresses "20 "To" 29 "occupied. Here, e.g. the DALI address "10" is assigned to the first output connection 12 of the first splitter unit 10, whereas a DALI address "19" is assigned to the right or last output connection 12 of this splitter unit 10 and the further addresses to the connections in between 12 can be distributed.
    The operation of the splitter unit 10 according to the invention is now such that when a DALI command arrives at the input-side connection 11, an internal logic of the splitter unit 10 determines whether the DALI address assigned to the command is one of the output-side connections 12 corresponds. If the incoming DALI command thus has address information that is to be assigned to one of the output-side connections 12, the splitter unit 10 forwards this DALI command according to the invention via the corresponding output-side connection 12, but now replaces the address information in such a way that it is is a broadcast command.
    The implementation of the address information when forwarding a command through the splitter unit 10 is shown schematically in Figure 2. The actual command or command section therefore remains unchanged, and only the area of the command which defines the address is replaced in such a way that it is now a broadcast command. This means that all lights 20 connected to the corresponding connection 12 automatically receive this command and implement it accordingly, even though no DALI operating address was assigned to them beforehand.
    In the event that the command arriving on the input side is already a broadcast command, this is then forwarded by the splitter unit 10 to all connections on the output side. This means that the command actually reaches all the lights 20 of the system 1, despite the interposed splitter unit 10.
    In an analogous manner, the transmission of feedback takes place, which can be provided according to the DALI standard for the case that a lamp 20 detects incorrect information and wants to communicate this to the central control unit. In this case too, the feedback - as shown in FIG. 3 - is initially forwarded to the splitter unit 10 without specific address information (or with any address). The splitter unit 10 in turn then outputs the feedback via the actual DALI bus 2 to the central control unit 100, but now adds the address information assigned to the corresponding output connection 12 to it. From the point of view of the central control unit 100 of the system 1, the splitter unit 10 is therefore completely invisible and the result is a communication which has always been carried out up to now. In particular, no modifications are required on the central control unit 100 which enable the splitter unit 10 according to the invention to be used.
    The operation of the splitter unit 10 described above illustrates that the full functionality of the DALI protocol can be used and lights or groups of lights can still be controlled in the desired manner. It is essential, however, that the lighting fixtures 20 no longer have to be assigned operating addresses, but it is only necessary to connect the lighting fixtures 20 in a suitable manner to the output connections 12 of the splitter unit 10. The establishment of the company addresses for the
    5.8
    AT16 348U1 2019-07-15 Austrian
    Patent Office
    Output connections 12 and thus for the connected lights 20 then only take place by assigning a corresponding start address to the splitter unit 10. This can be done electronically, for example, since the splitter unit 10 can communicate with the central control unit 100 in a classic manner via the DALI bus 2, as explained above. However, the start address itself is preferably set directly on the splitter unit 10 itself, in which case corresponding switches 13 or the like can then be provided.
    If, for example, the system according to the invention is used in a hotel as mentioned above, then all lights or consumers in all rooms can be connected in the same way to the associated splitter unit and it is only necessary to use the splitter units in each case Assign start address. However, no further measures are required, which means that it is immediately apparent that this results in significantly less effort when commissioning the system compared to assigning individual operating addresses to all lights. This advantage also arises in the event that only a single luminaire or a single consumer is connected to each output connection of a splitter unit, but is of course particularly important when a large number of luminaires are connected to the output-side connections.
    Finally, it should be pointed out that, of course, not only splitter units have to be connected to the central DALI bus, but of course individual lights or other consumers or sensors can also be connected here. As already mentioned, the central control unit of the system is not able to tell whether the connection to the consumers is made directly via the bus or via a splitter unit, which ultimately means that when using the splitter units according to the invention, there are no restrictions in terms of functionality of the DALI standard must be accepted.
