Definitions

  • the invention relates to a circuit according to the preamble of claim 1.
  • the error message takes place via a separate line to a display device common to numerous electricity consumers.
  • the invention has for its object to reduce the number of lines leading to a control center.
  • the invention has the advantage that the error message is sent via the control line, so that no separate message lines are required.
  • 1 designates an electronic switching device which contains a switching transistor 2, via which the current consumer 3 connected to the positive pole of the voltage source is connected to the ground potential which forms a negative pole.
  • the switch 4 located in an operating center is closed, the base of the transistor 2 is supplied with a control voltage which switches on the current consumer via a series resistor 5.
  • the magnitude of this control voltage is determined by the tens diode 7 to the value U z and is reduced by the voltage drop across the series resistor 5 compared to the voltage U of the voltage source.
  • This voltage U is also present at the window discriminator 7, which however is included this value does not pass current through the display element shown as indicator lamp 8.
  • the series resistor 5, the window discriminator 7 and the indicator lamp 8 are combined in a display device 9, which is located in the area of the control center.
  • the electronic switching device 1 is assigned fault detectors 10 and 11, of which the fault detector 10 supplies a signal to the OR gate 12 in the event of a short circuit in the consumer, the fault detector 11 in the event of an interruption in the consumer circuit.
  • the output signal of the OR gate 12 which arises in the event of an error causes the switch 13 to be closed, which is preferably designed as a controllable semiconductor, but could also be a make contact of a relay actuated by the output signal of the OR gate 12.
  • the switch 13 forms a controllable impedance which changes its resistance value from "zero" (closed) to "infinite” (open), but it would also be possible within the meaning of the invention, e.g. when using a switching transistor to cause a change in resistance between a first value that is greater than zero and a second value that is greater than the first but finite.
  • the difference in resistance causes the input resistance of the electronic switching device 1 to assume a lower value in the event of a fault, so that because of the then increased voltage drop across the series resistor 5, the input voltage at the window discriminator is also noticeably reduced.
  • the window discriminator 7 is designed in such a way that the output current for actuation of the input voltage which is noticeably reduced compared to the value U is Indicator lamp 8 emits, which thus indicates the existence of an error.
  • the window discriminator causes an error display if its input voltage is greater than U z , for example if the control line is interrupted incorrectly.
  • a ground short-circuit of the control line would be indicated anyway by the indicator lamp 8 lighting up, because then the input voltage at the window discriminator 7 is less than U.
  • the input resistance to be measured between control line 14 and ground can of course also be changed as a function of the error in that the switch 13 or a switching transistor controlled by the output signal of the OR gate 12 is arranged in series in the control circuit. However, the switch would then have to be opened in the event of a fault, so that a voltage which is greater than U Z is present at the window discriminator, which then causes the indicator lamp 8 to light up.
  • a qualitative evaluation of the voltage present on the control line 14 behind the resistor 5 by means of the window discriminator 7 enables a selective determination of various types of errors.
  • a particularly simple display device 15 is shown in FIG. 2, in which errors are indicated by a light-emitting diode 16 through which the control line current flows.
  • the display device 15 can be used in conjunction with the electronic switching device 1 shown in FIG. 1, but then the Zener diode 6 is not required.
  • the switch 13 When the switch 13 is open, that is to say if there is no fault, a small current flows in the control line 14, which does not light up the LED 16.
  • the current is particularly low when transistor 2 is a VMOS transistor. If, in the event of an error, the OR gate 12 causes the switch 13 to close, or if the control line is short-circuited to the ground, a higher current flows which causes the light-emitting diode 16 to light up. With a circuit according to FIG. 2, however, the interruption of the control line 14 is not indicated.
  • FIG. 3 An extended circuit for additional monitoring of the functionality of the brake light switch 4 'of a motor vehicle is shown in FIG. 3.
  • An OR gate 17 is located between the window discriminator 7 and the indicator lamp 8, as a result of which the error display explained at the outset is not influenced via the first input 18.
  • the second input 19 of the OR gate is connected to the output of an inverter 20, the input of which is connected on the one hand with high resistance (resistor 21) to the positive pole of the voltage source and on the other hand via a control switch 22 which can be actuated by the pressure of the brake fluid and via an AND provided for potential isolation -Gate 23 is connected to the connecting line between the switch 4 'and the resistor 5.
  • switch 4 When switch 4 'is open, this connecting line has ground potential, provided that: switch 22 is open. At the input of the inverter there is an H signal which has been converted into an L signal at 19. The indicator lamp 8 is de-energized.
  • the brake switch 4 If the foot brake is pressed, the brake switch 4 'is closed. An H signal is present at AND gate 23. If the control switch 22 speaks after the build-up of the brake pressure in the master cylinder, there is an H signal at the input of the inverter 20 and an L signal at the input 19 of the OR gate 17, so that the display 8 remains de-energized.
  • the inverter 20 receives an L signal after the control switch 22 has responded. An H signal is then present at its output, as a result of which the fault lamp 8 responds.
