Definitions

  • This invention relates to a remote control with selective evaluation of impulse patterns.
  • each impulse pattern representing either an individual command or a master command consists of an equal number of n elements, each of which can be, for example, an impulse or an impulse gap.
  • n elements each of which can be, for example, an impulse or an impulse gap.
  • Another property of the individual and master commands is that one individual command represents a combination of a freely selected class (m) of the n elements, whilst a master command represents a combination of another class (p) of the n elements.
  • a receiver which is designed to receive and evaluate an individual command is also equipped to evaluate a master command by virtue of the fact that, during reception, at least one of the n elements of the combination is not tested for consistency between the impulse pattern received and the individual command impulse pattern associated with the receiver.
  • the individual commands are formed, for example, by impulse sequences.
  • Impulse sequences of this kind are also known as impulse patterns or impulse telegrams.
  • the individual commands are, for example, in a binary code, and are generally combinations of a certain class of n elements where n denotes the number of stages in an impulse sequence of the kind in question.
  • Each stage of the impulse pattern is associated with a binary character of a first kind, for example an impulse, or a binary character of a second kind, for example an impulse gap.
  • a binary character of a first kind for example an impulse
  • a binary character of a second kind for example an impulse gap.
  • impulses and impulse gaps it is also possible in known manner to use position-modulated impulses or alternating-current impulses of different frequency, and the like for representing commands.
  • the present invention is hereinafter described with refrence to one example with impulses and gaps. However, it is pointed out that the invention is by no means limited to this type of impulse telegram or impulse pattern.
  • a total of 252 commands is obtained from 10 elements in combinations of the 5th class.
  • each command since each command generally has a counter command, for example to switch on or off a remote controlled switch, it is of advantage to form 126 pairs of commands from the total of 252 possible combinations.
  • the evaluation of pairs of commands such as these becomes particularly simple in terms of apparatus where inverse impulse patterns are used for the command and the counter command. Accordingly, it is of advantage to form the 126 pairs referred to above in such a way that each pair consists of impulse patterns that are inverse to one another.
  • the impulse pattern of a certain command reads, for example, as follows:
  • the impulse pattern represents a 5th-class combination of 10 elements. It contains the binary value 1 five times and the binary value 0 five times. According to what has been said above, the associated counter command thus has the following impulse pattern:
  • the commands a and b shall be individual commands.
  • collective commands master commands
  • collective commands are formed in such a way that their impulse patterns represent combinations of another class, for example, the 4th class, of n elements. Accordingly, there is a difference in class between the individual commands and the collective commands.
  • a collective command with which a suitably equipped receiver associated with the individual command a, for example, could be covered has an impulse pattern of the following kind for example:
  • a receiver with which the individual command a is associated is made to respond to a collective command c by virtue of the fact that the monitoring for consistency between the impulse pattern received and the impulse pattern associated with the particular receiver, which monitoring is carried out in stages, stops i.e., is interrupted in a certain stage of the impulse pattern.
  • monitoring would be interrupted in the 4th stage.
  • any non-consistency occurring in this 4th stage, as must intentionally occur in the transmission of a collective command does not have any effect upon the operative stage of the circuit element which is in its first set state.
  • the received impulse pattern 0 on completion thereof is accepted by the testing means.
  • the impulse pattern of the selective command c is also selectively evaluated by the receiver which is prepared to receive the individual command a, and the associated command carried out.
  • the counter collective command with the impulse pattern d inverse to c is also selectively evaluated by the receiver which is prepared to receive the individual command a, and the associated command carried out.
  • the present invention provides a method for remote control by means of impulse patterns associated with individual commands which consist of n stages of which a predetermined number of stages is occupied by binary characters of a first kind (0) whilst a similarly predetermined number of stages is occupied by binary characters of a second kind l
  • the arrangement is such that, during a transmission sequence, an impulse pattern associated with the particular command is transmitted which is tested for consistency with the impulse pattern associated with the particular receiver and, if accepted, is evaluated.
  • the method of the invention is distinguished by the fact that combinations of the same class of the n elements are used at the trans mitting end both for the formation of individual commands and also for the formation of collective commands although a first portion of the possible combinations is used to represent collective commands whilst a second portion of the possible combinations is used for forming individual commands. Further, the method is distinguished by the fact that, at the receiving end, monitoring or checking for consistency between the impulse pattern received and the individual command impulse pattern associated with the receiver stops in at least two of the n stages in the receiver which are designed to respond to collective commands. In addition, at least one binary character of the first type and one binary character of the second type are present in the unmonitored or unchecked stages of the received impulse pattern.
  • the invention also provides an apparatus comprising at least one circuit element which can be adjusted to two operative stages and a testing means.
  • the circuit element is adjustable into a set, first operative state, and the latest, on commencement of the reception of an impulse pattern.
  • the circuit element is constructed to retain this operative state up to the end of the impulse pattern if consistency between the impulse pattern received and the impulse pattern associated with the particular receiver is detected by the testing means in the monitored stages of the impulse pattern but which otherwise is displaced into the second state if the impulse patterns are inconsistent.
  • n 10
  • all commands are formed as 5th class combinations of 10 elements. Under the rules of combinatory analysis, this gives a total of 252 possible combinations, i.e., commands. Of these 252 combinations, 126 pairs of double commands are initially formed with impulse patterns that are inverse to one another. A first portion of these 126 pairs of commands, for example, 26, is reserved for collective commands, whilst the second portion, covering the remainder, is available for the formation of individual commands.
  • the ability to respond not only to an individual command but to a collective command as well, which is required for at least some of the multiplicity of receivers connected to a remote control system, is achieved by virtue of the fact that the monitoring for consistency between the impulse pattern received and the individual command impulse pattern associated with the receiver always stops for at least two stages; the stages in question being stages occupied by inverse binary characters. Accordingly, for example, one stage of the associated impulse pattern which is occupied by a binary character of a first type (1) and another stage which is occupied by a binary character of a second type (0) are not tested for consistency.
  • a collective command intended for the particular receiver differs in impulse pattern from the individual command impulse pattern associated with the particular receiver, for example, in two stages. However, the rest of the two impulse patterns are identical. In the case of different individual commands which can be covered by a common collective command, the position of the identical parts of the associated impulse patterns is different, although in two stages for example, there is never any consistency. As a result of the absence of any examination for consistency in these very stages, for example two in number, these receivers are also made to respond to the aforementioned collective command.

By contrast, the switch 25 isclosed-by the received starting impulse 1 for the period t,-to t 'in the time interval T At the end of the time interval T' i.e., at the time t the switch 25 opens again.

  • the received impulse pattern and the impulse pattern associated with the ripple control receiver for the ON- command will be assumed to correspond to FIG. 1.
  • bistable switching element 50a is actually brought into its non-conductive stage during the interval T, because, on the arrival of an impulse gap, the holding-current flowing through the circuit S to the switching element 50a through the diode 97, the
  • the impulse pattern received is inverse to FIG. 1, in other words if the associated remote control command is an OFF-command, a shunt is correspondingly formed through the command key 23 for the switching element 50 during reception of this inverse impulse pattern. As a result, the switching element 50 is brought into its nonconductive state. On the other hand, the switching element 50a retains its conductive state upon the completion of the inverse impulse pattern. As a result, a current impulse is delivered through the winding 92 of the impulse switch 59a during interrogation, i.e., during the period for which the switch 30 is closed. Under the effect of this current impulse, the impulse switch is brought into its OFF- position corresponding to the remote control command expressed by the inverse impulse pattern received providing the impulse switch is not already in this position.
  • FIG. 6 One embodiment of an electronic reversing switch 36a is shown in FIG. 6. This electronic reversing switch 36a performs the same function as the reversing switch 36 in FIG. 2 or FIG. 5.
  • the reversing switch 36a comprises a switching transistor 101 and a switching transistor 102. If the switching transistor 101 is conductive, positive voltage is delivered from the terminal 37 to the terminal 38. If by contrast the switching transistor 102 is conductive, positive voltage is delivered from the terminal 37 to the terminal 39.
  • an alternating current impulse removed by a filter (not shown) for the power supply system is delivered to the electronic switch 36a at an input terminal 103.
  • the alternating current impulse is rectified by a rectifier 104 and thereafter charges a capacitor 105.
  • the charging voltage of the capacitor 105 exceeds the Zener voltage of the diode 106, a currentflows to a resistor 107 and to the base 108 of the switching transistor 102.
  • the transistor 102 becomes conductive, i.e., the positive voltage at the terminal 37 is switched through to the terminal 39. Accordingly, a current flows through a diode 109 and a resistor 110 which is connected to a terminal 111 at negative potential. Through the drop in voltage across the resistor 110, the base-emitter voltage across the switching transistor 101 is so greatly reduced that the switching transistor 101 becomes blocked.
  • command sets 22 are connected to a single basic unit 21 of a ripple control receiver 20.
  • the individual command sets 22 have to be uncoupled with respect to one another in known manner by diodes 61a, 62a, 63a and 64a in the lines 61, 62, 63 and 64.
  • Each of the command sets 22 is also provided with its own command key 23 and accordingly only responds to the remote control commands determined by the command key.
  • the effectiveness of the shunts formed through the command key 23, the lines 61 64 and the stepping switch 40 in the event of non-consistency between the impulse pattern received and the impulse pattern associated with the ripple control receiver or one of its command sets 22, can be improved even further by connecting at least one diode (FIG. 7) in the forward direction between the cathode terminal of the bistable switching element 50 or 50a and the terminal 42.
  • a method for remote control comprising the steps of forming an individual command impulse pattern of a particular class of elements including a plurality of stages having a predetermined number of said stages occupied by binary characters of a first type and a predetermined number of said stages occupied by binary characters of a second type;
