Definitions

  • the invention relates to a circuit arrangement for the detection of switch-on sequences for a
  • On / off switch equipped with a first module containing a flip-flop for outputting a status signal.
  • the circuit arrangement is simple and can be used in many different fields.
  • a first capacitor C8 of a first module 11 is charged via the on / off switch when switching on via a charging resistor R9 and a first diode D8.
  • This charging voltage is conducted via a second capacitor C9 and led via a second diode D9 to the switching input of a flip-flop.
  • the flip-flop may consist of a logic gate, but it may also be implemented discretely.
  • the flip-flop is designed so that it assumes a defined state when the input signal is missing.
  • the first capacitor C8 is slowly and reliably discharged via a resistor RIO. Now, if the on / off switch is pressed again after a short time and thus closed, so much charge is stored in the first capacitor C8.
  • the capacitor charges itself correspondingly slower, and the lower voltage change rate means that only a small pulse is applied to the input of the flip-flop via the second capacitor C9 and the second diode D9, which can not switch over this. Since no input signal is present at the flip-flop, it falls into a defined state, which by suitable dimensioning of the resistors R3 and R4 and the presence of ClO, which connect the two outputs of the flip-flop in the discrete version with the power supply, is reached. Due to the additional voltage pulse via D9, the second input of the flip-flop, 'come up faster', and the flip-flop is thus in a different switching state than when switching on the circuit after a longer break.
  • the circuit of the first module 11 thus makes it possible to detect whether the device in question is switched on again after a longer switch-off time, or whether it was only briefly switched off and immediately switched on again. If several of these circuits are interconnected by means of switches, then you can use simple Switching on / off different consumers are switched on / off or a consumer can be switched to different modes.
  • FIG. 1a Circuit diagram of the circuit arrangement according to the invention in a three-stage embodiment.
  • FIG. 11 shows a circuit diagram of an embodiment of several consumers directly connected to the circuit arrangement according to the invention.
  • FIG. 2 Simple evaluation logic to switch different consumers on and off in succession.
  • Fig. 3 Some relevant signals to describe the mode of operation of a module.
  • FIG. 1 shows a three-stage embodiment of the circuit arrangement according to the invention.
  • An on / off switch S a voltage converter 3 is switched on and off, which supplies the circuit arrangement according to the invention with voltage.
  • the voltage converter is supplied by an input voltage U E.
  • the input voltage may be a DC or AC voltage, eg a mains voltage.
  • a first capacitor C8 is charged via the series connection of a first diode D8 and a first resistor R9 with a defined first time constant ⁇ l.
  • the time constant is small and charging is therefore fast. This can be clearly seen in Fig. 3, in which the signal 22 represents the voltage across the first capacitor C8.
  • the first capacitor is discharged again via a resistor RIO connected in parallel with a second defined time constant ⁇ 2.
  • This time constant is significantly greater, so that the unloading process takes a significantly longer time.
  • the charging voltage of the first capacitor C8 is conducted via a second capacitor C9 and a second diode D9 to the input E1 of the flip-flop. Since the first capacitor C8 charges very fast, this generates at the second diode D9 a pulse 242, which brings the downstream flip-flop for switching.
  • the status signal at the output A1 of the flip-flop is logic 0 and can be evaluated accordingly.
  • the second capacitor discharges via the discharge resistors RIO and RIl, as well as the first capacitor Cl via the discharge resistor RIO. If the on / off switch is switched off only for a short period of time and then immediately switched on again, as the signal 20 in FIG. 3 shows, the first capacitor C8 discharges only very slightly, as can be seen from the signal 22 in this figure . When restarting, therefore, a charging current only flows for a short time, and the voltage change at the first capacitor is relatively low, resulting in a very small voltage pulse 244 at the diode. This pulse is not high enough to switch the flip-flop. By means of a suitable dimensioning of the resistors R3 and R4 which connect the outputs A1 and A4 to the voltage supply, it is achieved that the flip-flop is defined when the input signal is missing in a state in which the output A1 is logic 1.
  • the signal 26 in Fig. 3 represents the current across the second diode D9. It is good to see that at the first turn on, a high current pulse flows through the diode, resulting in the switching of the flip-flop, while after a short time Switching off and on again no current flows because the voltage across the diode is lower than its forward voltage.
  • the signal 26 represents the voltage across a third capacitor ClO. This is needed to obtain a defined turn-on sequence from the flip-flop.
  • the signals 27 and 29 represent the voltages across the resistors R6 and R5, which represent the state of the associated outputs A1 and A4.
  • a control gear for lamps can be controlled, that according to the three state signals 31, 33 and 35 sets different dimming levels of the lamps.
  • the system can be switched off again by the switch S at any time. But if, as at time t3, only briefly and immediately turned on again, so the flip-flop of the first module 11 to swing, and the output Al is at logic 1. This has the consequence that the second module 13 is turned on. For the second module, it is but a switch on after a long break, since it was previously switched off. Thus, the first output A2 of the second module remains at logic 0. In the state table 41 at time t3, therefore, the switch S and the first output Al of the first module to logic 1. The signals can be evaluated accordingly to a consumer in another Condition to operate. For several consumers, e.g. one is switched off, since now the second output A4 of the first module 11 is at logic 0. This is e.g.
  • the consumer 17 in Fig. Ib the case. If the output A4 is set to logical 1, the LED driver is switched on, the output oscillates to logical 0, the driver and thus also the LED D5 is switched off. The consumers 18 and 19 remain switched on in this state, since the second outputs A5 and A6 of the modules 13 and 15 are still at logical 1.
  • the circuit according to the invention can remain switched on for any desired length of time. As long as the modules are supplied with power, their condition does not change. Decisive are the shutdown breaks. If the shut-off pauses are short, a state is incremented each time it is switched on again. The last possible state remains with repeated switching off and on, as can be seen from the logic diagram in FIG. If the shutdown break is longer, the circuit is reset and starts again at the first state. After switching off and on again, the circuit is therefore in the, second 'state, in which S and Al are at logic 1. [29] Of course, the signals of the outputs and the switch can be further linked in order to achieve a specific behavior of the circuit.
  • the signals can be linked in accordance with the circuit in FIG. This is constructed with simple AND gates and inverting Schmitt triggers, and switches outputs Z1-Z4 according to the states after the row. This switching through can be found in the logic table 43. When switching on for the first time (after a long pause), the output Zl is at logic 1, at the second switch-on (after a short switch-off) the output Z2, etc. With other logic connections, naturally also any other behavior can be achieved.
  • the circuit according to the invention can be used, for example, to produce different lighting scenarios in an old house installation by means of only one light switch merely by briefly switching it off and on again.
  • the circuit according to the invention can also be used to produce different states in electrical appliances with only a simple switch. This is advantageous, for example, in the case of an LED flashlight in which all LEDs are switched on in the first state when first switched on. After switching off and on again, some of the LEDs are switched off, etc. Thus, depending on the number of interconnected modules, different dimming positions can be switched.
  • the big advantage of the circuit is that they are switched off again at any time can, without switching through all states, as is the case with a mechanical multiple switch. This significantly improves the usability of the device.

Abstract

L'invention concerne un arrangement de circuit destiné à détecter les séquences de mise en marche d'un commutateur marche/arrêt, comprenant un premier module (11) qui contient une bascule bistable (50) pour délivrer un signal d'état. Selon l'invention, lors de la mise en marche, un premier condensateur (C8) du premier module (11) est chargé par le biais d'un commutateur marche/arrêt (S) par une source d'alimentation (3) à travers une première diode (D8) et une résistance de charge (R9) ayant une constante de temps de charge (τ1) et cette tension de charge est acheminée par un deuxième condensateur (C9) et par le biais d'une deuxième diode (D9) pour être appliquée à l'entrée de commutation de la bascule bistable (50) dont la première (A1) et la deuxième (A4) sortie délivrent alors des signaux d'état correspondants en vue de leur interprétation. Toujours selon l'invention, lorsque l'arrangement de circuit est désactivé, le premier condensateur est de nouveau déchargé à travers une résistance de décharge (R3) avec une constante de temps donnée (τ2) et la constante de temps de charge (τ1) du premier condensateur est nettement inférieure à la constante de temps de décharge (τ2). L'invention concerne également un procédé pour commander différents états d'une ou plusieurs charges. Selon l'invention, les états sont permutés par une simple déconnexion et reconnexion d'un commutateur marche/arrêt (S) dans une période de temps donnée.
