Definitions

  • Circuit arrangement for switching off the actuator outputs in the ASI system in the event of data communication failure
  • the invention relates to a circuit arrangement for the defined switching off of output switching stages, which are supplied with DC voltage via a circuit of a slave communicating with a master in an ASI system, the circuit having a positive, a negative DC voltage connection and a connection which trigger pulses only occur during data communication between the master and the slave.
  • the actuator sensor interface (ASI) (the actuator sensor interface for automation, Werner Kriesel, Otto W. Madelung, Carl Hanser Verlag, Kunststoff - Vienna, 1994) is for data exchange between a large number of participants intended. It is a so-called “single master system” in which one master controls the data exchange for each line strand. He calls the slaves lying in the wiring harness one after the other and awaits their response. Each slave is assigned its own address as an identifier, via which it can be called. Since each slave can transmit 4 Bi data and a maximum of 31 slaves (31 addresses) can be connected per line string, there can be a maximum of 124 binary participants on an ASI line with static operation of the four data lines. In the bidirectional operation of the four data lines, the number of participants can be expanded to 124 actuators (outputs) plus 124 sensors (inputs).
  • the invention is therefore based on the object of providing a circuit arrangement for the defined shutdown of the actuator outputs in the actuator / sensor interface system in the event of data communication failure.
  • the circuit arrangement has a timer which can be controlled by the trigger pulses and which opens a downstream electrical switch after the trigger pulses have failed, so that the output switching stages are cut off from the supply with the DC voltage.
  • timing element has a combination of a capacitor and a first ohmic resistor, which is fully charged with each trigger pulse and, after the trigger pulses have failed, with the resultant from the capacitor and the first ohmic resistor Time constants are discharged so that after the minimum control voltage of the subsequent electrical switch is undershot, the latter opens.
  • the circuit arrangement is advantageously carried out in detail in such a way that a second ohmic resistance lies between the connection and the positive DC voltage connection, that a parallel connection of the capacitor and the first ohmic resistance is provided, which on the one hand with the positive DC voltage connection and on the other hand via a Diode is electrically connected to the emitter of a first transistor, the base of which is connected to the terminal and the collector of which is connected to the negative direct voltage terminal, that the connection point between the diode, on the one hand, and the first resistor and capacitor, on the other hand, is led to the base of a second transistor, the Collector is connected to the negative DC voltage connection and whose emitter is connected via a third ohmic resistor to the base of the switch designed as a third transistor, whose emitter is connected to the positive direct voltage connection and to whose collector the output switching stages, for example relays, are connected, a fourth ohmic resistor being connected between the The basis of the third transistor and the positive direct voltage connection lies.
  • FIG. 1 shows the circuit arrangement according to the invention for the defined switching off of output switching stages.
  • each slave of the "ASI system" described at the beginning there is a special circuit 1 which, according to FIG. 1, is provided with a connection 2, the so-called data strobe connection, and DC voltage connections 6, 7.
  • the circuit arrangement according to the invention for the defined switching off of actuator outputs 5 in the ASI system is located at these connections 2, 6, 7 if the data communication between the master and the respective slave fails.
  • the circuit arrangement essentially consists of a retriggerable timer 3 and an electronic switch 4 which can be controlled by it.
  • the circuit is constructed as follows:
  • the retriggerable timing element 3 consists of two transistors 9, 10 and a parallel connection of a capacitor 11 and a nem ohmic resistor 12, the parallel connection being connected on the one hand to the positive DC voltage connection 6 and on the other hand via a diode 13 to the emitter of the transistor 9, the base of which is connected to the connection 2 and the collector of which is connected to the negative DC voltage connection 7.
  • the connection point 14 between the diode 13 on the one hand and the resistor 12 and the capacitor 11 on the other hand is led to the base of the transistor 10, the collector of which is also connected to the negative DC voltage connection 7.
  • Its emitter is connected via an ohmic resistor 15 to the base of the further transistor 4, which is connected downstream of the timing element and whose emitter is connected to the positive DC voltage connection 6.
  • a resistor 16 is provided between the base of transistor 4 and the positive direct voltage connection.
  • the function of the circuit is explained with reference to FIG 2, where four curves are shown.
  • the top curve shows different phases of the ON and OFF switching of data communication between the master and the slave.
  • the ASI circuit 1 in the slave emits a trigger pulse U 1 according to the second curve in FIG. 2 to its address on the data strobe connection 2 with each master call.
  • the retriggerable timer is triggered with this signal U1. If the master calls and thus the trigger pulses fail, the downstream transistor 4 is opened after the time tz specified by the timing element has elapsed, and the connected output switching stages 5 switch off.
  • This is illustrated by the third curve U2 with the potential of the connection point 14 in relation to the negative DC voltage connection 7, which corresponds to the differential voltage between the DC voltage and the voltage at the capacitor 11 and the fourth curve with the supply voltage U3 of the output switching stages 5.

Abstract

Le circuit selon l'invention permet une mise hors circuit définie des étages de commutation de sortie (5) d'un système actionneur-capteur-interface, en cas de panne de communication de données. Cette mise hors circuit est obtenue au moyen d'un dispositif de temporisation (3) commandé par des impulsions de déclenchement apparaissant au niveau de la connexion (2), qui sert aux impulsions de transfert de données, du circuit de commutation (1). S'il n'y a pas d'impulsions de déclenchement, un commutateur électrique (4) monté en aval s'ouvre, de sorte que les étages de commutation de sortie (5) sont coupés de l'alimentation en courant continu.
