Definitions

  • the invention relates to applications in which the consumer is switched on or off hard for energy-saving or other reasons. As a result, these devices do not have a "stand-by mode", making it difficult to control various operating modes through a single on / off switch.
  • the object is achieved by a circuit arrangement according to claim 1.
  • the circuit arrangement is simple and can be used in many different areas.
  • a first capacitor C2 is charged via the on / off switch when switching on via a charging resistor R3 and a first diode.
  • This charging voltage is conducted via a second capacitor C1 and conducted via a second diode 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 in the absence of input signal.
  • the first capacitor is slowly and defined via a resistor discharged. 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. The capacitor charges itself accordingly slower, and the lower voltage change rate causes only a small pulse is applied to the input of the flip-flop via the second capacitor and the second diode, which can not switch this. Since no input signal is present at the flip-flop, it falls into a defined state, which is achieved by suitably dimensioning the resistors and the presence of C3, which connects the two outputs of the flip-flop in the discrete version to the power supply becomes. Due to the additional voltage pulse via D2, 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 long break.
  • the circuit thus makes it possible to detect whether the device in question after a longer off time is turned on again, or whether it was only briefly off and immediately turned on again. This can e.g. be used to dim a flashlight when switching to a first light level, and to dim after a short off and on again to a second light level.
  • the first diode is replaced by two Zener diodes, which in turn are connected to two flip-flops. This is a time-dependent representation of four states or three Switch-on states possible, which can be evaluated by the connected load.

  • the first capacitor is again discharged via a resistor R3 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 on / off switch is first switched on, the charging voltage of the first capacitor C1 is conducted via a second capacitor C2 and a second diode D2 to the input E1 of the flip-flop. Since the first capacitor Cl charges very quickly, this generates at the second diode D2 a pulse 242 which causes the downstream flip-flop to switch over.

  • the signal 26 in Fig. 4 represents the current across the second diode D2.

Abstract

L'invention concerne un arrangement de circuit pour détecter des séquences de mise en marche pour un commutateur marche/arrêt comprenant une première bascule bistable (30) destinée à délivrer un signal d'état. Selon l'invention, un premier condensateur (C1) est chargé par une source d'alimentation (3) par le biais d'un commutateur marche/arrêt lors de la mise en marche à travers une première diode (D1) et une résistance de charge (R3) avec une constante de charge (1) et cette tension de charge est acheminée aux bornes d'un deuxième condensateur (C2) puis appliquée par le biais d'une deuxième diode (D2) à l'entrée de commutation de la première bascule bistable (30), dont la sortie (A1) délivre alors un signal d'état correspondant en vue de son interprétation. Selon l'invention, le premier condensateur est de nouveau déchargé avec une constante de temps définie (2) à travers une résistance de décharge (R3) lorsque l'arrangement de circuit est en position arrêt. L'invention concerne également un procédé pour générer un signal d'état en se basant sur l'actionnement en fonction du temps d'un commutateur marche/arrêt comprenant les étapes suivantes : - Génération d'une courbe de tension avec une dépendance au temps donnée lorsque le commutateur marche/arrêt est en position marche, - Différentiation de la courbe de tension pour générer une impulsion de tension, - Application de l'impulsion de tension à un ou plusieurs éléments à valeur de seuil, - Application du signal résultant à un ou plusieurs éléments de mémorisation pour représenter le signal d'état.
