Definitions

  • the present invention relates to a circuit arrangement according to the preamble of the claim 1.
  • railway light signaling systems are extremely reliable required.
  • the plants which are generally exposed to high environmental pollution, should function without problems over a long period of time and any defects that may occur immediately report to a control body.
  • One is from the Swiss patent specification CH 675 922 Railway light signal system known, which is provided with two light bulbs. This from just a few, Circuitry existing for non-critical components is simple in construction and therefore largely immune to external influences (especially temperature fluctuations).
  • a disadvantage of This well-known railroad light signal system is that the life of the light bulbs used is relatively short. The maintenance required for these systems is therefore still fair high.
  • the light intensity of the lamps is difficult to match the lighting conditions at the plant location adjust because incandescent lamps have a non-linear behavior. For the sake of simplicity the lamps are therefore always operated with one or two power levels.
  • the overall function Known railroad traffic signal systems essential due to the failure of a single lamp influenced.
  • the present invention is therefore based on the object of providing a circuit arrangement which has increased operational reliability compared to known systems and which to unit to be replaced is compatible.
  • the circuit arrangement according to the invention allows the use of light-emitting diodes, such as those e.g. in Klaus Beuth, Bauimplantation, Vogel Verlag, Würzburg 1991, 13th edition, page 292-294 are. It is known from this that light-emitting diodes react almost without inertia and one to forward direct current give proportional light intensity. LEDs are also for different wavelength ranges (including infrared) available and have a good (but depending on the wavelength) Efficiency. It is also known that LEDs compared to incandescent lamps have a much higher life expectancy.
  • the circuit arrangement according to the invention can be used instead of the circuit arrangement to be improved without changes in the existing infrastructure or in the course of operations.
  • FIG. 1 shows a circuit arrangement according to the invention, which has a primary side with an AC voltage input INP and on the secondary side via a rectifier circuit GS with n lighting units BE1, ..., Bn connected transformer XFMR.
  • the input INP of the circuit arrangement is installed via a line with the supply circuit of a main station or a railway signal box. An AC voltage is generated from this supply circuit given, the amplitude for day and night operation between two values is switched.
  • the change in amplitude is the circuit arrangements provided with incandescent lamps adapted as they are known from the aforementioned patent specification CH 675 922.
  • the rectifier circuit GS shown in FIG. 1 which is known to the person skilled in the art, consists of a bridge rectifier formed from four diodes D1, D2, D3 and D4 as well as a charging and a Filter capacitor C1 or C2.
  • Rectifier circuits switching power supplies, etc.
  • the connections of the primary or secondary winding of the transformer are against overvoltages XFMR each connected to a protective element Rs (e.g. a resistor or varistor, etc.).
  • the connections of the primary winding of the transformer XFMR or the connections of the input INP are also connected to each other by a resistor Rg (base load resistor).
  • Each lighting unit BE1, ..., BEn has one connected to the rectifier circuit GS Current source ICV1 on, in series with a winding of a relay RLS11, with a series resistor Rv and a group CL1 of LEDs LD1, ..., LDx is connected.
  • a relay RLS11 For current limitation through the winding of the relay RLS11 can also be connected in the reverse direction parallel to the relay winding Zener diode (see Fig. 3, diode ZD) are used by the voltage across the relay RLS11 is limited.
  • the relay RLS11 has a switch contact K11 through which another Relay RLS2 can be connected to the connections of the primary winding of the transformer XFMR.
  • the circuit arrangement shown in FIG. 1 functions as follows:
  • An AC voltage is applied to the input INP of the circuit arrangement by the main station supplied, which is transformed in the transformer XFMR and delivered to the rectifier circuit GS becomes.
  • a current is generated by the current source ICV1 connected to the rectifier circuit GS through the winding of the relay RLS11 and the diodes LD1, ..., LDx.
  • the lighting units BE11, ..., BE1n provided relays RLS11, ..., RLS1n therefore become the contacts K11, ..., K1n closed, after which a current is passed through the winding of the relay RLS2. This causes the contact K21 to close and the contact K22 to open. over A current is therefore passed through the resistor Rr to the first contact K21.
  • the second relay RLS2 is preferably with forced guidance due to the requirements Contacts.
  • Such safety relays are in Hans Sauer, Relay Lexicon, Wegig Verlag, Heidelberg 1985, 2nd edition, pages 199-201.
  • the contacts K21 and K22 therefore exist each from two serially connected contacts, one of which can always be disconnected, even if the second contact is welded.
  • a and the same error such as Contact welding or spring breakage, only on one contact at a time occurs. Errors that occur within the safety relay are detected by a (in FIGS. 1 and 2 (not shown) evaluation circuit that also detects an error when evaluating next switch-on prevented.
  • Fig. 2 shows a lighting unit BEc, which is supplemented by a module TN, which for day / night switching the light intensity emitted by the diodes LD1, ..., LDx. Furthermore, a measurement and Amplifier circuit provided, which consists of a photosensitive element PSD (Photo resistor, element, diode or transistor, as described in Klaus Beuth, components, Vogel Verlag, Würzburg 1991, 13th edition, chapter 12) and at least one amplifier OP2, whose output is connected to a control input of the current source ICV1.

  • the voltage source UC connected to the input of the lighting unit BEc is connected in parallel to the series connected resistors R1 and R2.
  • the TN module works as follows:
  • the main station outputs the maximum voltage provided to the INP input the circuit arrangement.
  • the voltage delivered by the main station is calculated for the operation of incandescent lamps.
  • the in the circuit arrangement according to the invention provided diode groups CL1, ..., CLn and that from the transformer XFMR and the Rectifier circuit GS existing power supply part must therefore be designed such that at least approximately the same luminance as when operating with incandescent lamps.
  • the voltage applied by the main station to the INP input is lowered to adapt the luminance of the optical signals to the changed environmental conditions and to achieve a reduction in the energy output.
  • the lowering of those delivered by the main station Voltage is in turn adapted to the circuit arrangements provided with incandescent lamps, to which the circuit arrangement according to the invention is to be compatible. Since the in the Lighting unit BEc provided current source ICV1 the current despite the lowering of the Keeping the voltage constant (e.g. so that the RLS11 is not reset) is used for night operation the shunt resistor Rn switched on, so that the series connected diodes LD1, ..., LDx only a fraction of the original current is carried, which is sufficient to operate a light bulb to achieve comparable luminance.
  • the shunt resistance Rn must be taken into account that light-emitting diodes and incandescent lamps have different characteristics exhibit. In the case of light-emitting diodes, the emitted light intensity changes proportionally in contrast to incandescent lamps to the supplied electricity.
  • the differential amplifier OP1 detects the (variable) voltage taken from the voltage divider compared with the constant voltage output by the voltage source UC.
  • the through The resistors R1 and R2 formed voltage divider is designed so that during daytime operation there is no voltage difference at the input of the differential amplifier OP1. Only through that Lowering the input voltage when switching to night mode creates a voltage difference, through which a control signal arises at the output of the differential amplifier, which for Activation of the switching unit SWb leads.
  • the switching unit SWb e.g. a switching transistor, switches then the shunt resistor Rn parallel to the diode group provided with the series resistor Rv CL1. When switching to day mode, the switching unit SWb is reset.
  • the shunt resistor shown in FIG. 2 Rn can also be connected to the current source ICV1 and from the differential amplifier OP1 actuated switch SWa can be provided, through which a lower constant current is set for day operation can be used as for night operation.
  • These units provide an electrical control signal to the control input of the power source ICV1 supplied by the through the element PSD (preferably looking towards the Light signal) depends on the measured luminance of the environment.
  • the ambient brightness drops the current carried by the diode groups CL1, ..., CLn is therefore reduced.
  • the characteristic of the Amplifier OP2 is chosen such that the desired difference in luminance is always present is. It is also provided that the holding current for the relays RLS11-RLS1n is never undercut.
  • a symbol to be signaled is preferably formed by at least two diode groups CL1, CL2 educated.
  • the light-emitting diodes LD of these groups CL1, CL2 are arranged in such a way that if a group CL1 or CL2 fails, e.g. caused by the interruption of a diode LD the symbol remains recognizable.
  • the symbol is used by both Groups CL1, CL2 are displayed, which means that if a group CL1 or CL2 fails, only one Luminance drop occurs.
  • the traffic light system therefore remains in operation until that of the main station reported bugs is fixed.
  • the resistors Rg and Rr base and residual load resistance
  • these load resistances can be taken into account the transformation ratio of the transformer XFMR can also be arranged on the secondary side.
