Definitions

  • the invention relates to a circuit according to the preamble of claim 1.
  • a circuit is known from DE-PS 35 16 612.
  • the DC indicators are used to identify the signal term in each case and to identify the effective lamp filament of an activated signal lamp.
  • the different signaling states are differentiated by evaluating the polarity of DC voltages; the DC voltage detected in each case is switched in the vicinity of the lamp via differently polarized diodes and exclusion contacts from signaling devices to the feed lines to the signal lamps and is coupled out at a remote monitoring point via DC indicators.
  • a lamp monitor which detects the feed current flowing over the main thread of the respective signal lamp and, if the feed current is sufficiently high, disconnects a secondary thread connected in parallel with the main thread for reserve purposes from the supply voltage.
  • the auxiliary thread of the signal lamp is automatically activated.
  • the auxiliary thread of a signal lamp is always functional and can take over the task of the failed main thread in the event of a fault.
  • Light signal circuits are also known in which the respective secondary thread of a signal lamp is checked for functionality. This is the case, for example, with the circuit known from DE-PS 35 15 962. There, the auxiliary thread of the signal lamp is also briefly switched on each time a signal lamp is switched on and when the signal lamp is switched on. If the secondary thread is live, a feedback to a Monitoring point given, which then causes the shutdown of the previously switched on thread. In this known circuit there is no constant monitoring of the secondary thread for functionality. In addition, the individual connection of the auxiliary threads for testing purposes and the feedback of the corresponding reporting status to an evaluation point requires a relatively high amount of hardware only for the functional test of the auxiliary threads on the individual signal lamps.
  • the object of the invention is to provide a circuit according to the preamble of claim 1, which enables continuous function monitoring of a replacement thread for the duration of the connection of a lamp without the need for an additional current indicator or other signaling device in the monitoring circuit of the replacement thread in question.
  • the drawing shows a signal lamp L of a multi-term light signal, not shown, which from a remote control point via isolating transformers T1 and T2 is operated with AC voltage. This AC voltage is constantly present;
  • the signal lamp L is switched on and off by contacts FU1 / 1 and FU2 / 1 of lamp monitors, which are assigned to other signal lamps of the light signal. If the signal lamp L shown is, for example, a signal lamp provided for switching on the stop term, the contacts FU1 / 1 and FU2 / 1 are contacts of the lamp monitor assigned to, for example, two travel signal lamps of the light signal.
  • the supply voltage for the driving signal lamps is not constantly switched through to the signal lamps; if necessary, it is created by switching contacts.
  • a DC monitoring circuit which leads via the feed lines leading to the signal lamp, the two lamp threads of the signal lamp connected in series and at least one DC indicator.
  • the DC monitoring voltage is derived from the constant supply AC voltage via diodes D1 and D2 connected in opposite polarity and upstream exclusion contacts W / 2 and W / 3. As long as a sufficiently high alternating current flows through the main thread H of the connected signal lamp L, the AC indicator W is excited.
  • the contact W / 2 in series with the diode D1 is closed and a monitoring current circuit is formed via this diode, the secondary thread N of the signal lamp, then distribution of the path via main thread H of the signal lamp, primary winding of a current transformer feeding the AC indicator W and the transformer T2, the DC indicator G1 and the feed lines S of the signal lamp.
  • the DC indicator G1 indicates when set the presence of the correct operating state of the signal lamp L.
  • the main thread is monitored by the AC indicator W.
  • Resistors R prevent the monitoring direct current from energizing the secondary filament of the signal lamp which is not switched on beyond its glow limit.
  • the AC indicator W drops, for example, when the main thread of the signal lamp burns out, it opens its contact W / 2 and closes its contacts W / 1 and W / 3.
  • a DC monitoring current now flows via the diode D2, the contact W / 1, the DC indicator G2 and the feed lines of the signal lamp.
  • the response of the DC indicator G2 indicates the fault that has occurred.
  • exclusion contacts W / 2 and W / 3 of the alternating current indicator assigned to the signal lamp in the monitoring circuit of a signal lamp can also be used to switch the direct current indicators on and off as required, for example switches which indicate whether the respective signal lamp is switched on of the light signal, e.g. a driving signal lamp, the main or the secondary thread is effective.
  • the monitoring of the respective signal term is carried out via direct current indicators (not shown in the drawing) which are assigned to the travel signal lamps of the light signal and can be connected via meshing between the feed lines of the individual signal lamps.
  • the invention shows a way to check the auxiliary thread of the signal lamp for operational readiness in addition to the main thread of a signal lamp that is currently switched on, or to monitor both the main and the signaling process in the reporting process Include a thread of a signal lamp. Any errors that would have a detrimental effect or jeopardize the operation only in the event of a malfunction when the main thread of a signal lamp burns out, are thus recognized at an early stage, so that there is the possibility of a timely rectification of the malfunction before the danger occurs.
  • the invention is also applicable to the monitoring of signal lamps without double filament lamps. There, a replacement lamp takes over the function of the secondary thread according to the exemplary embodiment explained above.
