    The present invention relates to a method for transmitting control commands in a system distributed units arranged, for example. In a lighting system with distributed lights. Furthermore, the invention relates to a corresponding system with distributed units, with the help of the invention, in particular a temporally synchronous behavior of all units in the execution of control commands is sought.
    Larger lighting systems in which a plurality of lights, for example. Are controlled by a central control unit, bring in comparison to each individually locally controlled lighting units the advantage that easier and more efficient coordinated behavior of all lights can be achieved. This means, for example, that all lights within a given period of time, e.g. during normal working or opening hours, are activated together and their brightness coordinated so that overall seen a homogeneous light output is achieved. Such a coordinated behavior is desirable, for example, in public buildings or larger premises such as open-plan offices or workshops, as this results in a much more pleasant appearance.
    A well-known in such systems problem consists in that, although relatively simple in terms of the light output matched behavior of the lights can be achieved, a time-synchronous behavior of the lights, however, is much more difficult to implement. The reason for this is that, as a rule, the luminaires do not independently change their behavior at certain predefined times, but instead a control command is issued by a single primary command transmitter, which is to be received by all luminaires and converted accordingly. However, the transmission of this control command to all lights of the system takes a different time depending on the position of the lights. This is because usually the original command issued by the primary commander does not reach all of the lights, but instead is repeated by individual units of the system, ie retransmitted, so that it cascades across the entire system until it is actually out of all Lights was received. Receiving and retransmitting the control command, however, each takes a certain period of time, so that, for example, luminaires which receive the command only after the third repetition react much later than those luminaires which receive the command issued directly by the primary commandor to have. This can be, for example, then make noticeable by the fact that after a centrally issued command to turn on the lights with increasing distance from the commander from only successively activate, which is quite noticeable to an observer.
    Incidentally, the problem described above is independent of whether the control commands are transmitted via a signal line or wirelessly, e.g. transmitted by radio or infrared radiation, since in both cases, in particular in larger arrangements, the control command must be repeatedly sent in order to spread over the entire system can. Also concerns the problem not only lighting systems, but also other systems with distributed arranged consumers, where it is desired that the consumer after issuing a control command substantially simultaneously respond to this.
    The present invention is therefore based on the object, in distributed distributed systems consumers or units to avoid the disadvantages described above and to optimize the temporally coordinated behavior of the units after issuing a central control command.
    1.15
    The object is achieved by a method for the transmission of control commands, which has the features of claim 1. Furthermore, the object is also achieved by a system of distributed units according to claim 10. Advantageous developments of the invention are the subject of the dependent claims.
    The central idea of the solution according to the invention is that a unit that has received a control command, this does not necessarily immediately implements. Instead, it is provided that the control command contains information regarding an already existing command transmission time and each unit determines an individual waiting time on the basis of this command transmission time, after which the command is first executed by the unit.
    According to the invention, a method for transmitting control commands distributed in a system arranged units, for example. Proposed in a lighting system with distributed lights, at least a portion of the units sends a received control command again to forward the control command to all units wherein the control command includes information regarding a previously issued command transmission time, and wherein each unit determines an individual maintenance time based on the command transmission time contained in a received command, after which the command is executed by the unit.
    The lights that, for example, directly receive the output from the primary control command command, so do not execute this immediately, but first wait a certain time before the command conversion takes place. According to the invention, this waiting time can now be determined on the basis of the command transmission time contained in the command in such a way that the command is not implemented until it has actually been received by all subscribers of the system. This ensures that all luminaires or generally all units of the system essentially react at the same time and accordingly a cascade-like switching on of the luminaires is prevented. Although 100% synchronous behavior of all units of the system is not necessarily achieved by the procedure according to the invention, however, the deviations are only so slight that they can hardly be perceived by an observer. This also applies to the critical case of lighting control, in which temporal deviations are particularly easy to observe.
    In order to enable the participants of the system to be able to determine an individually suitable waiting time for themselves, the units must therefore know which period has already passed since the output of the original control command. This is ensured according to a preferred embodiment of the invention in that each unit that retransmits a received control command adds a delay time taking into account the reception and forwarding of the command transmission time contained in the control command and then retransmits the control command with the updated command transmission time obtained thereby. Preferably, each unit that retransmits a received control command in the manner described above then determines its individual waiting time after retransmission of the control command based on this updated command transmission time.
    Each unit which forwards a command is thus aware of how much time is required for the reception and forwarding of the command signal. This is then added to the command delivery time contained in the received command and issued as a new updated value. Thus, since the signal propagation time itself is negligible compared to the time required to receive and resend the control command, the command transmission time primarily provides a summary of the reception periods required by the units responsible for signaling Processing and forwarding of the signal. This approximation is quite sufficient for the desired effect, namely to achieve an observer in principle, the same time behavior of all units of the system.
    Calculating the individual waiting time by each unit may then preferably
    2.15
    AT16 476U1 2019-10-15 austriictiei iBlfrUril be effected by determining the difference between a global transmission duration for the control command and the command transmission time contained in the command. That is, all units are aware of a global delivery time that provides information about the time within which all units of the system will actually receive the command. Further, because the units know how much time has elapsed since the original control command was issued due to the command delivery time contained in the command, they can then easily determine how long to wait before exporting the command.
    It can be provided here that the global transmission duration is independent of the starting point of the control command and, for example, is set once when commissioning the system. This is the simplest variant and results in the global delivery time having to be tuned to the extreme case where the control command is issued at one end of the system and must propagate to the other end across the entire array of units, ie the maximum delay time for the complete spread of the control command exists. However, since this would mean that in the event that the command, for example, is issued rather centrally and thus propagates much faster, the units wait an unnecessarily long time before synchronizing the command, according to a particularly preferred embodiment also be provided that the global transmission duration is determined depending on the starting point of the control command.
    This can be done, for example, by the fact that the one commander who sends the control command for the first time, this also adds information regarding the global transmission duration. In this case, therefore, each of the system's commanders, which theoretically sends a control command for the first time, must know what time elapses before the command has fully propagated in the system. Alternatively, it can also be provided that only information is added to the control command, which provides information about which command generator has sent the control command for the first time. In this case, each unit must independently determine the resulting global transmission duration. In both cases it is necessary that the corresponding information be determined at least when the system is first put into operation and, ideally, also be updated during the later operating period, as changes in the system itself or in the area or building in which the system is installed , Can affect the way the command propagates.
    From the above descriptions it follows that therefore first the inventive method is based on the idea to add the transmitted control command temporal information and calculate based on waiting times. It is provided according to a particularly preferred embodiment of the invention that the specification or calculation of the transmission time, the waiting time and possibly the global transmission duration is not based on exact time values, but instead in discrete magazines or time units. This measure means that the transmission of the corresponding times as well as the calculation of the periods can be carried out clearly practicable, in particular simpler and faster, and if necessary also information with regard to the resulting global transmission duration can be stored with little effort. As will be explained in more detail below with reference to the description of the figures, this leads to only slight losses with regard to the synchronous behavior of the units, so that, despite all, significant advantages can be achieved in comparison with methods known from the prior art.
    Finally, it is ensured with the aid of the procedure according to the invention that, despite complex signal propagations, the units of the system react simultaneously from the perspective of an observer regardless of the size of the system.
    The invention will be explained in more detail with reference to the accompanying drawings. Show it:
    Figure 1 shows schematically the spread of a control command in a larger Beleuch3 / 15
    AT16 476U1 2019-10-15 austriictie iBlfrUril management system;
    Figure 2 shows the timing of the propagation of the signal to the implementation by the lights of the system shown in Figure 1;
    Figure 3 is a schematic representation to illustrate the inventive behavior of the various lights of the system shown in Figure 1 and Figure 4 shows an example of a matrix for storing the transmission times.
    The invention is explained in more detail below with reference to a lighting system in which control commands wirelessly - ie. by radio or infrared - transmitted to distributed lights of the system. As already mentioned, however, the present invention is not limited to lighting systems, even if temporal deviations of the units of the system are the easiest to perceive here. However, synchronous behavior of the various units may also be desired in other systems, for example in a system for centrally controlling shading devices such as blinds or the like, which is why the invention is very versatile.
    Furthermore, the procedure according to the invention is also transferable in a simple manner to systems in which the signal transmission does not take place wirelessly but instead via corresponding physical lines. This can be the case, for example, if complex bus systems exist in which a plurality of different subsystems are connected to one another and, accordingly, a repetition of the control command must inevitably take place at the interfaces.
    Figure 1 shows schematically in this context, for example, a floor of a building in which a generally provided with the reference numeral 100 lighting system is used. In the illustrated embodiment, the illumination system 100 comprises a plurality of distributed switches or sensors sw1 to sw5 and a plurality of distributed lights L1 to L18. As can be seen, the various switches or sensors sw1 to sw5 and lamps L1 to L18 are not all arranged in the same space, but may well be arranged in walls and corridors separated by walls. Despite all, it is desirable that when issuing a control command, which relates to all the lights L1 to L18, the lights L1 to L18 as possible at the same time implement this command accordingly.
    It should be noted that in the present case with the aid of the invention is only sought that the lights L1 to L18 behave synchronously in time, so run, for example, a global control command simultaneously. On the other hand, it is irrelevant in which way the command is actually implemented by the lights L1 to L18. That is, it may well be that a command causes individual lights to emit light at maximum brightness, while other lights, for example, located near windows of the building, a reduced brightness taking into account the outside incident light accept. However, it is desired that the luminaires L1 to L18, irrespective of which brightness they finally assume, make the change to the new brightness initiated by the control command essentially simultaneously, whereby it should be understood at the same time that deviations are as small as possible that they are no longer perceptible to a human observer. Further, of course, the invention does not exclude that a command concerns only a single or a part of the luminaires, ideally always those luminaires which are addressed together with a command should react at the same time.
    In the present case, it is now assumed that a control command is initially output from the switch sw1, which should cause all lamps L1 to L18 to turn on. In the same way, however, the primary control command could also be issued by one of the luminaires L1 to L18 themselves, for example due to a changing situation (for example a change in the daylight from outside or also the detection of a state of emergency) a new operating state
    4.15
    AT16 476U1 2019-10-15 austriictiei iBlfrUril wants to accept and the other lights of the system 100 should in turn behave in the same way. As units of the system according to the invention, therefore, both the switches or sensors sw1 to sw5 and the lamps L1 to L18 are considered in the present case.
    In the illustrated embodiment is therefore - as already mentioned above - assumed that initially the control command is transmitted primarily by the switch SW1 wirelessly. However, the range of the output from this switch sw1 signal is limited, which is due for example to the various walls of the building, which can be penetrated only greatly attenuated by the signal. In the same way, even with a wired signal transmission, a limitation of the range may be present, for example, in that several subsystems exist and the primary command transmitter can only transmit signals within a subsystem.
    In the present case, the range of the output from the switch sw1 signal containing the control command is represented by the first dashed curve I, which as can be seen such that only the lights L1, L2, L4, L9, L15 and L16 and the switch / sensor sw2 receive the signal. In this context, for the sake of simplicity, it is assumed that the units of the system 100 either receive a signal completely / correctly or are not received at all. Of course, intermediate states can also occur in reality, such that, for example, a signal is received only incompletely or with such low intensity that it is not reliably detected with sufficient certainty. For the sake of simplicity, such intermediate states will be understood hereinafter as non-receipt of the signal.
    That is to say, the control command originally issued by the switch sw1 is received only by a part of the lights of the system 100. However, since it is intended that all lights should implement this command, it is provided that - as previously known from the prior art - of at least one of the lights that have received the control command, this is transmitted again. This signal repetition now has a new range (curve II) and causes the control command is now also received by the lights L3, L5, L6, L10, L11, L17 and L18 (as well as the switches SW3 and SW4). This procedure continues in the same way repeatedly. That is, one of the lights that have received the first signal repetition, the signal again turn out - with the range III - send out, so this then in the next step by the lights L7, L8, L12, L13 and L14 and the switch sw5 Will be received. In the illustrated embodiment, the control command was thus received by all units of the system 100, but in reality also significantly more signal repetitions may be required, until finally the command has reached all units.
    In solutions known from the prior art, the luminaires have hitherto been designed so that they implement this as soon as possible after receiving a control command, so turn on in the present example. This would result in the switching on of all lights of the system 100 cascading in three successive stages, depending on the respective signal ranges I, II, III of the originally issued control command or the repeated control commands. The resulting time differences arise less due to the propagating with the speed of light signals themselves as to be carried out in the responsible for the signal repetition operations with respect to the reception, processing and retransmission of the signal. These processes lead to delays, which ultimately lead to a successive switching on the lighting groups, which is quite noticeable to an observer.
    In the past, attempts have been made to keep these delay times as low as possible in order to reduce such effects. However, since the processes for processing and retransmitting the signals can not be arbitrarily shortened, this did not lead to completely convincing solutions. In contrast, the present invention proposes a
    5.15
    AT16 476U1 2019-10-15 cinematici iBlfrUril A novel approach to avoid the problems described above in an elegant and efficient way.
    Put simply, the inventive method provides that the lights of the lighting system 100 after receiving a control command with its execution wait until it is ensured that the last light of the system 100 has received the command and can implement it. Only then do all the lights more or less simultaneously execute the command, the remaining time differences being so small that they are no longer perceptible to a human observer.
    Simplified, the principle of the invention will first be explained with reference to FIG 2. Shown here is the time course after the beginning of the original transmission of the control command until its implementation.
    Thus, at the time t 0, the first-time signal output takes place, whereby at the time L the signal is first repeated by a unit of the system. In the period between the times t 0 and L with the duration Ä! (In fact, at the beginning of this period) all lights will receive the control command that is within the signal range of the primary commander, within the range of the switch sw1 in the example described above. This includes, for example, that unit which is responsible for the renewed signal output at time L. The delay time Ä! results in particular from the required for the reception, processing and signal transmission steps within this unit.
    In the adjoining delay period Δ 2 then those lights receive the command, which are in signal range of the signal repeating the signal for the first time. A second repetition of the control command by at least one of these lights takes place at time t 2 . This process is repeated until the time t N , at which the signal or the control command is repeated for the last time N times. This signal is then detected by the last remaining lights of the system and these are after a final delay period Δ Ν + 1 - which is required by the lights to evaluate the command and prepare its execution - at time T T tl (where the abbreviation TTL for Time-To-Light) will be able to execute the command.
    According to the invention it is now provided that all participants of the system, the time T ttl is known and only at this time the command is implemented, regardless of the time at which the individual light has actually received the command. That is, all the lamps together wait for the time T T tl and then execute jointly and synchronously the command.
    In order for each luminaire to determine for itself individually how long it must wait until the received command is delivered, two conditions must be fulfilled.
    Firstly, the luminaire must know the total duration T ttl , which is also referred to below as global transmission duration and indicates how long it takes after the output of the original signal until all participants of the system have received the command and are able to to implement it.
    On the other hand, each luminaire must, upon receiving the signal, know how much time has elapsed since the original transmission of the signal.
    In this context, it would be conceivable in a first step to assume that the delays for the signal repetition, ie the periods shown in Figure 2 Δ! to Δν are the same size. However, this would require that all users of the system are identically formed with respect to the components responsible for the signal reception and the forwarding and, accordingly, actually need the same amount of time for this. However, since the system according to the invention should be as flexible as possible and, in particular, even when using different types of luminaires with different associated electronics should nevertheless ensure synchronous working, it must be ensured
    6.15
    AT16 476U1 2019-10-15 austriictiei iBlfrUril be assumed that the delay times are actually dependent on which light or generally which participant of the system performs a signal repetition.
    In order to take this into account, it is provided according to the invention that upon transmission and repetition of the control command, this information is additionally supplemented with information relating to the already past command transmission time and this information is updated in each case by the luminaire, which repeats a command. Each fixture that then receives a command can thus determine how much time has already passed, based on the command delivery time contained in the command. Based on this information as well as the global command transmission duration, each light can then individually determine how long it must wait before actually executing the command.
    This procedure will be explained in more detail below with reference to Figure 3, which refers to the scenario shown in Figure 1, in which at time t 0 by the switch sw1 originally the control command is issued. Further, the signal at the time L by the light L2 and the time t is repeated by the light L17 2, wherein after the second signal repetition all the lights of the system 100 have received the command.
    It should be noted that preferably for practical reasons, the specification or calculation of the command transmission time, the waiting time and the global transmission duration is not in absolute time details such as milliseconds or microseconds but instead a standardized specification is made in discrete magazines. The advantage of this approach is that all time values are given in natural, integer numbers and accordingly can be easily integrated into the signal. In contrast, the effort required to transmit and calculate absolute time values would be considerably more complex.
    These discrete time steps are referred to so-called slot values t S | Ot normalizes, whereby this journal t S | Ot should correspond at most to the shortest delay time of a signal repetition, but ideally it should be lower. The result of the signal repetition caused by a particular subscriber of the system delay time Δ η is then expressed in the inventive process in integer values, the Hop Counts so-called, which is calculated as follows:
    h c n & n / t s iot These delay times are then added to the control command as already mentioned and enable the lights, as described in more detail below, to individually determine how long they wait to execute the received control command have to.
    In the embodiment shown in Figures 1 and 3, this means that, first of all, the lights the total delay time T ttl is known, which is normalized to the timeslots now 9 so-called hop counts. If now at time t 0 for the first time sent from the switch sw1 of the control command, this command as already above mentioned additional information concerning the already past signal transmission time added, which however is in primary emission of the signal 0th The so-called hop count hc added to the control command is therefore 0.
    This output from the switch sw1 signal is - as shown in Figure 3 - received, for example, from the light L1, the signal reception takes place almost immediately, so the lamp L1 receives the signal shortly after the time t 0 . On the basis of the hop count hc contained in the signal, which as explained is 0, and the known global transmission duration Tttl = 9, the luminaire L1 then individually calculates an individual delay time TTL1, which corresponds to the difference between the global transmission duration T ttl and the already past signal transmission time that is 9. In absolute time values, therefore, the lamp L1 waits for a waiting time TTL1 which is 9 times the discrete time value t S | Ot corresponds.
    7/15
    Like luminaire L1, luminaire L2, just after instant to, receives the primary signal output by switch sw1 with hop count hc = 0. However, luminaire L2 is used for signal repetition responsible, that is, it receives the signal, processes it and sends it again at time L. For this the lamp L2 requires an individual delay time hc! = 2 and accordingly adds an updated hop count hc = 2 to the repeated control command. After issuing the command, the luminaire L2 then calculates for itself a delay time TTL2 starting with the issuing of the command, which in turn corresponds to the difference between the global transmission duration and the signal delay time and is therefore now 7.
    For the other lights that directly receive the primary signal, so the lights L4, L9, L15 and L16 applies to the lamp L1 said. These lights also receive the primary signal with the hop count value 0 and accordingly calculate a delay time of 9, which is 9.
    The light L3, however, receives the signal repeated by the lamp L2 with the updated hop count value 2. After receiving this signal calculates the lamp L3 in turn an individual delay time in an analogous manner to the already discussed lights. Thus, as with the luminaire L2, which has calculated its delay time only after the repeated signal has been output, the result is a delay time of 7. The same applies to the luminaires L5, L6, L10. L11 and L18.
    The procedure of the responsible for the second signal repetition lamp L17 is analogous to the procedure of the lamp L2, wherein the lamp L17 requires a longer time hc 2 = 3 for the signal repetition. The value 3 is now added to the signal delay time, so that an updated delay time hc = 2 + 3 = 5 results, which is added to the signal output at time t 2 . After the signal has been output, the luminaire L17 calculates an individual delay time of 4 for itself.
    The lights of the third group, which receive the signal repeated for the second time all, then calculate on the basis of the updated signal delay time hc = 5 for each an individual delay time 4.
    In general, therefore, that the signal transmission time hc added to an instruction corresponds to the sum of the delay times hc resulting from the previous signal repetitions, and is therefore calculated as follows:
    i = n hc = hei i = 0 For the individual delay time TTL in d then:
    TTL ind = Ttl - hc i = n
    TTL ind = T tl - hei i = o Each luminaire then executes the command after the individually determined delay time has elapsed, wherein FIG. 3 shows immediately that the command execution takes place substantially simultaneously. There are only slight deviations from one another, which result from the slightly different signal propagation times, but these deviations are clearly below the duration of a single timeslot, ie are so small that they are not recognizable to a human observer. Ultimately, all lights act simultaneously from the point of view of an observer.
    The procedure according to the invention thus results in a simple manner in that, from the point of view of an observer, the luminaires of the system 100 actually implement synchronous commands, even if the command transmission takes place in the course of several signal repetitions. In the above description, for the sake of simplicity, it was assumed that
    8.15
    AT16 476U1 2019-10-15 c Austrianiictiei iBlfrUril the repetition of a signal takes place in each case only by a single luminaire. In fact, the procedure according to the invention would also be applicable if, for example, several or even all of the luminaires which are located in the transmission range of the primary transmitter, in this case the switch sw1, carry out a repetition. It then only has to be determined that each luminaire performs a signal repetition at most once and, after calculating the individual waiting time, ignores the receipt of further possible signal repetitions. Thus, the luminaires do not have to make a complicated agreement as to which luminaire is responsible for the respective signal repetition, but can firmly act according to a predetermined but easily performed scheme.
    A further advantage of the procedure according to the invention is that the luminaires themselves can calculate their individual delay time in a relatively simple manner, since only the difference between the global transmission duration and the transmission time already passed must be calculated. Thus, if the global transmission duration is known, the effort to calculate the individual delay time is extremely low. There are different options for determining the global transmission duration, which will be explained in more detail below.
    A first possibility would be to specify a fixed, unchangeable global transmission duration for the entire system, as shown for example in FIG. Of course, this must then be sized to take into account the maximum time for the transmission time of a signal from any primary commander to all lights. This case is in the example of Figure 1, in which the signal propagates continuously from one end of the building over the entire length to the other end.
    If, however, the primary signal in the system shown in Figure 1 emanate instead from the switch sw3, then it can be assumed that the command spreads faster over the entire system, since it is now distributed in two opposite directions and a maximum of one additional signal repetition will be required. In this case, the global transmission duration T T tl = 9 would be set too high and would mean that all the lights would wait unnecessarily long, until they finally but as desired - synchronously implement the command. It would therefore be advantageous in this case or in general to choose a shorter global transmission duration, which depends on the starting point of the primary signal. For this purpose, two variants are conceivable.
    On the one hand, the unit that primarily transmits the command could simultaneously specify the global transmission duration and also add this information to the control command.
    Alternatively, only information could be added to the control command that provides information about which unit originated the control command. On the basis of this information, each luminaire can then determine the resulting global transmission duration and then in turn calculate the individual waiting time taking into account the command transmission time.
    In both variants, it is necessary to know how long the transmission of a signal from any command generator to any receiver of the system is. This information must be present or determined at least when the system is put into operation, and is then preferably stored in a matrix, as shown schematically in FIG. The content of a field of the matrix indicates the signal transit time (again in timeslot values) between the command generators specified in the lines and the recipients specified in the columns. The diagonal of the matrix remains understandably without entries or is 0, since the signal transit time of a participant of the system to itself is always equal to 0. If, however, a primary signal is now output by a specific user of the system, then the maximum value of the entries contained in the corresponding line allows the determination of the global transmission duration.
    9.15
    The knowledge of these matrix entries thus makes it possible either to add the global transmission duration directly to the origin of the signal, ie to the primary commandor, or to the receiving luminaire knowing the origin of the signal To determine transmission duration. Again, it is advantageous that the signal propagation times are given in discrete, integer values, as this significantly reduces the effort required to save the matrix. In addition, compression algorithms known from the prior art can also be used to further reduce the memory requirement.
    The signal propagation times and thus the content of the matrix must, as already mentioned, be determined when the system is put into operation. It is preferably provided that, moreover, an update of the matrix entries takes place at least even at regular intervals during operation of the system, since redesigns not only of the system itself but also of external influences can definitely lead to significant changes in the signal propagation times. For example, adding walls or even furniture within the building can cause a signal to propagate significantly in different ways, faster or slower.
    Ultimately, however, the measures described above lead to the fact that the behavior of the different participants of the system can be much better coordinated with each other in time and thus, for example, in a lighting system, the overall appearance of lighting can be significantly improved. As already mentioned, a particular advantage of the procedure according to the invention is also that the expense for realizing the method is relatively low.
