  • the code signals are also transmitted from the central stations to the emergency call pillars via the above-mentioned phantom circuit.
  • the code signals consist of a sequence of alternating current pulses with different voltage values.
  • the voltage values Ul, Uh, Um used (cf. Fig. 5) are generated in the central locations in a known manner by voltage shift keying.

  • the code signals are transmitted from one of the manned central stations ZB either directly to the emergency call stations or indirectly via an unmanned central station ZU.
  • the code signals in the manned central station are converted into a form suitable for data transmission, transmitted on the continuous voice line to the unmanned central station, converted there into the original code signals and transmitted from there to the assigned emergency call pillars.
  • each emergency call pillar NRS (cf. FIG. 3). These are part of the signal lamps SL1 to SL4 (see FIG. 2). All signal lamps are attached by brackets Ha close to the head part KT of the emergency column. This avoids large leverage effects in strong winds.
  • one, two or three signal lamps light up in succession. Since several signal lamps are provided, different light sequences can be formed and thus more information can be signaled.
  • Fig. 3 shows an embodiment for the generation of a desired flash sequence in an emergency column.
  • code signals are transmitted from one of the central stations to the emergency call pillars and there, via phantom decouplings Ph2, to a transmitter U4 with a plurality of secondary windings s, z, b.
  • the voltage tapped at the secondary winding s is rectified in a rectifier and charging device GLE and fed to a signal device SE as code signal voltage Us and evaluated there.
  • a power supply capacitor Cv (cf. FIG. 4) is charged in the rectifier and charging device GLE by the code signals transmitted with high energy. Its voltage is used to power various electronic circuits; this is indicated by the voltage arrow Uv.
  • An exemplary embodiment for the rectifier and charging device GLE and details about the derivation of the voltages Ub, Uz, Us and Uv are explained with reference to FIG. 4.
  • a corresponding type signal TS (cf. FIG. 6) at the output of the signaling device SE provides appropriate information which specifies the type of blinking.
  • the signaling device SE in FIG. 3 contains a commercially available series-parallel converter, which converts the series information arriving at the input of the pulses arriving one after the other into parallel information at the output; this is indicated by a multi-core connection line to a distributor Vt in a lightning sequence circuit Bfs.
  • the parallel information at the output of the signal device SE controls the distributor Vt of the flash sequence circuit BfS in the flash device BE in such a way that the switching points 1 '...
  • the energy required for the flashing operation is also transmitted via the phantom circuit on the stems St1 and St2.
  • the voltage supplied is stepped up in the secondary winding b of the transformer U4, rectified in the rectifier and charging device GLE and fed as a flash voltage Ub to the flash tubes BR1 ... 4 in the flash device BE.
  • the flash voltage Ub is smoothed by the charging capacitor Cb.
  • the diode D prevents the energy of the charging capacitor Cb from flowing back.
  • the flash sequence circuit BfS has a clock switch T, which is controlled by a counter ZG.
  • 50 Hz half-waves serve as counting criteria, e.g. the supply voltage for the emergency pillar outside lighting or for the lighting of the mileage.
  • the counter ZG switches the clock switch T cyclically step by step after a predetermined number of half-waves.
  • the ignition voltage Uz formed in the rectifier and charging device GLE via the secondary winding z is cyclically switched through to one of the switching points 1 '... 4'.
  • the ignition voltage Uz is applied in succession to ignition transmitters Ü5.1 ... Ü5.4 in the desired order.
  • a glow lamp and a flash tube with auxiliary electrode are assigned to each of these ignition transmitters.
  • a glow lamp GI1 and a flash tube BR1 with auxiliary electrode H1 are shown.
  • the ignition trigger shown in Fig. 3 represents an external triggering of the ignition, in contrast to the usual method in which the ignition timing is determined by the charge state of an energy store (see e.g. DE-AS 1 933 436).
  • the charging times of the charging capacitors Cb, Cz for the lightning voltage Ub and the ignition voltage Uz are dimensioned such that the charging capacitors have reached their intended charging energy by the next switching step of the clock switch T.
  • FIG. 4 shows an exemplary embodiment for the generation of the voltages Ub, Uz, Us and Uv shown in FIG. 3.
  • the AC voltage U decoupled from the phantom circuit is raised in the secondary winding b of the transformer U4 directly to the value required for the flash tubes, fed to a full-wave rectifier Gb of the rectifier and charging device GLE and output as rectified, still unscreened voltage Ub.
  • the usual voltage stabilization which is primarily used to keep the flash sequence frequency constant, is not necessary since, as already mentioned, the ignition is triggered independently of the charge state of the charging capacitor Cb (cf. FIG. 3).
  • the capacitor Cz is charged with the voltage taken from the transformer winding z via a diode D9.
  • a low voltage is tapped from the transformer winding s and rectified in a rectifier Gv.
  • the power supply capacitor Cv is charged with the rectified voltage via the diode D11 and the resistor R11.
  • the code signals are also taken from the winding s and, after rectification in the rectifier Gv, are fed to the signal device SE for evaluation as a code signal voltage Us. Since the code signal transmission works with two different voltage values and the power supply capacitor Cv is recharged during the code signal transmission, the voltage across Cv is stabilized by a Zener diode Z11. The diode D11 prevents the charge from Cv from reaching signal-evaluating parts of the signaling device SE. The resistor R11 is used for decoupling.
  • the circuits fed with the supply voltage Uv are integrated circuits, so that their power consumption is very low compared to the flash tubes.
  • FIG. 5 shows the example of a sequence of 5Q-Hz alternating current pulses transmitted via the phantom circuit in its time profile t for activating an emergency call pillar.
  • the alternating current is represented by the hatching within the pulses.
  • the alternating current is sensed in the central stations.
  • the pulse sequence shown covers the period from the start of the code signal transmission, starting with a charging pulse 11, followed by signal pulses Is, an activation pulse la for initiating the blinking operation BB until an end pulse le, which ends the blinking operation and the deactivated emergency call stations for the next blinking operation ready. Further details on this are explained in connection with FIG. 7.
  • the charging pulse 11 has a longer duration than the subsequent signal pulses Is.
  • the charging pulse 11 is used to charge the power supply capacitor Cv (cf. FIG. 4), which feeds the electronic devices of the light signal device.
  • the code signals KS consisting of the signal pulses ls, are binary coded.
  • the voltage criterion is used exclusively among the various possibilities for forming the two binary states.
  • the low voltage Ul embodies the binary state zero.
  • the higher voltage Uh embodies the binary state L.
  • the individual pulses are separated from one another by pauses RZ, in which the voltage returns to zero.
  • the two voltage values Uh or Ul are designated in FIGS. 3, 4 and 7 after their transformation and rectification with the common term code signal voltage Us.
  • FIG. 6 shows a simplified, unipolar representation of an impulse example for a group of five code signals KS, which are assigned to an emergency call pillar.
  • a group of five code signals corresponds to five different flashing cards.
  • the code signals consist of the address signal AS and the type signal TS.
  • the address signal determines the emergency call column to be activated and is therefore different for each emergency call column.
  • the address signal comprises 5 bits.
  • the type signal specifies the number of signal lamps activated by the flash sequence and their switch-on sequence and thus the position of the emergency call columns within a group of flashing emergency call columns as well as the type of information.
  • the type signal TS consists of 3 bits.
  • the flashing mode BB takes place.
  • the voltage used here is equal to the voltage Uh.
  • the flashing mode is in the activated, ie flashing the signaling device SE is switched off for the emergency call pillars NRS and the non-activated, ie non-flashing emergency call pillars are separated from the phantom circuit, with the exception of a threshold switch, via which the remote supply takes place.
  • These switching measures are carried out with the aid of an activation device AE (cf. FIG. 7).
  • FIG. 7 shows an activation device AE of an emergency call column and the means for carrying out the switching measures mentioned above.
  • Signateinrich-i device SE lightning sequencer BfS and counter ZG, and the generation of voltages Ub, Uv and Us in the rectifier and charging device GLE have already been explained with reference to FIGS. 3 and 4.
  • the AC voltage arriving via the stems St1 and St2 of the phantom circuit is decoupled via the phantom decouplings Ph2, for example chokes tapped in the middle, and supplied to the transmitter U4 via normally closed contacts b1 and b2 of a relay B in the activation device AE.
  • the primary winding of transformer U4 is grounded to the center.
  • the activation device AE has threshold switches consisting of Zener diodes Z1 and Z2, whose breakdown voltage Ud lies above the voltage Uh of the charging pulse 11 and the flashing mode BB (cf. FIG. 5). As long as the Zener diodes Z1 and Z2 are blocked, a negligible current flows through the activation device.
  • Zener diodes for example, thyristors or Schmitt triggers can also be used.
  • the signal device SE switches the supply voltage Uv through the control line S1 (not shown in FIG. 3) and a relay contact a3 to the relay A. Its excitation circuit is closed via contact a4.
  • the relay: A responds. The while flipping the relay contacts. a3 and a4 brief interruption. of the excitation circuit is bridged by the capacitor Ca.
  • the closing contacts a1 and a2, which are parallel to the normally closed contacts b1 and b2, prepare the activation in such a way that; when the break contacts b1 and b2 are opened later, the transformer U4 remains connected to the phantom line.
  • the winding of the relay A is separated from the supply capacitor Cv in the rectifier and charging device GLE.
  • the two relays A and B are magnetic, bistable latching relays. The contacts of relay A therefore remain in their new position despite being switched off by the supply capacitor Cv until the relay is brought back to its original state by a pulse of opposite polarity. Relay A does not react to further pulses of the same polarity.
  • the control line S2 controls the flash sequence circuit BfS.
  • Their switching state which controls the ignition sequence of the signal lamps SL, is stored by means of the supply voltage Uv.
  • the voltage reference point 0 of the lightning sequence circuit BfS is connected to the supply capacitor Cv via the diode 12 and the contact b3.
  • the diode D2 prevents the voltage zero point of the signal device SE from remaining connected to the capacitor Cv via the diode D3 when the contact b3 is switched.
  • the diode D3 prevents the counter ZG from being connected to the capacitor Cv during the code signal transmission via D2 and b3 and thereby unnecessarily stressing it.
  • the activation of the other emergency call column is prepared in the same way, in that its relay A is activated and the switching state of the lightning sequence circuit BfS which arises is stored.
  • the voltage on the phantom line is then briefly increased to the value Um (see FIG. 5), which is above the breakdown voltage Ud.
  • This voltage Um is supplied via the contacts b4 and n and via the diode D4 to the Zener diode Z1.
  • the resulting breakdown current generates a positive current surge of the duration of the activation pulse la via the diode D4 (cf. FIG. 5). This current surge first switches the relay P and, delayed by a capacitor C, the bistable magnetic latching relay B.
  • the positive current surge also reaches the winding of the relay A via the previously switched contacts a3 and a4. This does not react to this, as it has already done so was brought out of its original position by a positive current surge and can only be switched back there by a negative current surge.
  • Contact p4 which switches before contact b4, causes voltage Um to be present at zener diode Z1 for as long as activation pulse la continues, even after contact b4 is switched. During the switching of the contact b4, the excitation of the relay B by the capacitor C is maintained.
  • the various charging time constants can be coordinated with one another in such a way that relay P or N responds before relay B in this case too.
  • the flash sequence circuit BfS is connected to the supply capacitor Cv either via the diode D2 or via the diode D3, regardless of the respective switching position of the contact b3.
  • folding b3 has no effect, since there opened contacts b1 and b2 separate all devices connected to transmitter U4 from the feeding phantom circuit.
  • the contact b3 which flips over in all emergency telephones at the same time, also closes the power supply circuit of the ZG counter.
  • a differentiating element can be provided in the counting device, which derives a pulse from the inrush current surge, which simultaneously brings the counting device into its zero position in all emergency call columns. This ensures that the counters of the activated emergency call stations work synchronously and that this ensures the mutual allocation of the ignition times according to a planned timing diagram.
  • the counters of the non-activated emergency call stations remain connected to their power supply capacitors Cv during flashing. However, due to the open contacts b1 and b2 and the open contacts a1 and a2, this is disconnected from the remote supply.
  • the voltage Uh is applied to the phantom circuit. It is less than the breakdown voltage Ud.
  • the threshold switches Z2 of all emergency call columns remain in the locked state during the flashing mode. Their leakage current is negligible.
  • the blinking operation is ended by the end pulse le.
  • the activation pulse la Like the activation pulse la, it has the voltage Um (see FIG. 5). This is connected via contact b4, contact p and diode D5 to Zener diode Z2. This is broken.
  • the resulting current surge is negative because of the diode D5. It brings the bistable magnetic relays A and B, which were previously brought out of their rest position by positive current surges, into their original position, shown in FIG. 7.
  • the activation device AE is thus ready for a new use after the end pulse le.
  • the relay N has the same function as the relay P in the previous positive current surge.
  • the voltage drops on the feeding message are of different sizes.
  • the line resistance corresponding to a last-fed emergency call pillar is taken as a basis and the voltage selected to be so large that the voltage rise above the breakdown voltage Ud in the last-fed emergency call pillar results in the required minimum response currents generated.
  • the response currents generated are then greater than in the last-fed emergency call pillar, but the resulting greater load on the relays is not detrimental to them, since the voltage surge is only very short and is only so great that in of the last-fed emergency call pillar, only the minimum response currents occur.
  • the series-parallel converter mentioned in the explanation of FIG. 3 is expediently designed in such a way that the output information for controlling the relay A and the lightning sequence circuit BfS is only available via the control lines S1 and S2 with a corresponding preceding address signal. In this way, control processes are only triggered in the three emergency call pillars to be activated. The performance required for this then remains limited to these three emergency pillars.
  • Corresponding converters are known as integrated logic circuits.
