  • Each lamppost such as 19 in each zone comprises an illuminating unit such as 20, for example a bulb and a transmitter module such as 21, housed for example in its base, supplied by the electrical circuit of the lamppost.
  • the transmitter module is equipped with a current consumption detector which controls an oscillator connected to a frequency of its own.
  • the oscillator only works if the lamp is out of order.
  • This signal whose frequency is significantly different from that of the AC 50 Hz network, for example between 5 and 100 KHz, is injected through the power line supplying the lamppost to the power supply cabinet in the manner of carrier currents.
  • the alternative supply network is used as a carrier on which one or more additional frequencies which are different from one another corresponding to the ignition faults of each bulb are superimposed.
  • all the modules in the same zone are each set to a different frequency to differentiate the signals reaching the power cabinet.
  • a receiver module such as 22 intended for transmitting the detection signal after encoding to the monitoring computer 17 of the control room 18 is provided in each supply cabinet.
  • This module manages, codes and transmits detection signals to the control room computer, allowing it to locate faults and then report them to the maintenance team.
  • receiver and transmitter modules in their particular functions will now be examined below according to a first embodiment in accordance with a so-called analog version shown in FIGS. 1, 2 and 3.
  • the transmitter module 21 comprises a detector 23 of consumed current, for example a voltage detection circuit 24, connected to the terminals of a resistor 25 in series with the bulb.
  • This current detector controls an oscillator 26.
  • the control of the oscillator is such that it is blocked during a current consumption considered as normal and emits a signal in the event of ignition failure, that is to say say in the presence of an abnormal consumed current.
  • Each floor lamp is assigned a frequency allowing its identification.
  • This specific frequency signal is injected into the supply circuit from the zone to the cabinet by an adaptation interface 27 through a group of capacitors. insulation 28.

  • This microprocessor 36 controls the sampler 33 and the encoder 34 for the transmission of information by telephone.
  • the codes are stored once and for all at the microprocessor 36.
  • a power supply unit 38 supplies the supply current to the various circuits.
  • the encoder 34 assigns to each recognized frequency? a code made up of two letters and four numbers. The first two letters and the first two digits are reserved for the area they represent and the last two digits for the row of the bulb concerned.
  • the lighting fault results in an abnormal intensity consumed in the lamp post concerned.
  • the consumption detector When the power is turned on, the consumption detector only controls the oscillator, which delivers a frequency signal specific to the lamp, only if the bulb does not work.
  • This frequency is transmitted by carrier current on the line to the receiver module whose frequency analyzer detects the presence.
  • the sampler on instruction from the microprocessor 36, will emit a signal which will be coded according to the received frequency making it possible to identify the floor lamp from the code it has in memory.
  • the coded signal is transmitted by the telephone line to the central computer, which will thus be able to identify the lamp post and direct the intervention and maintenance teams to the zone of the lamp post carrying the defective bulb.
  • the frequency of the signal from the oscillator of the transmitter module is significantly different from that of the power supply network.
  • the oscillator signal is strongly and sufficiently attenuated by the windings of the zone transformer included in a cabinet specific to each zone.
  • the difficulty is therefore, in this case, to selectively identify the identical frequency or frequencies emitted by different zones and to allocate them respectively to the zone or zones concerned, whereas all the energy sources of the zones are electrically connected in parallel to the same single unique TRAFO transformer without insulation for said frequencies.
  • the digital variant described below aims to remedy this drawback by adding a microprocessor to the oscillator of the transmitter module, directly carrying out the encoding according to which then, for each lighting unit in each zone, a first code called row code conveyed by carrier current to the zone cabinet, then completed by a second code called zone code, the full code being transmitted by telephone lines at a central monitoring station.
  • This modification makes it possible to make the invention independent of the area transformer (s) and thus significantly expand its applications, not only to all types of lighting networks, but also to all electrical energy distribution networks such as traffic signaling and regulation lights and, more generally, the distribution of electrical energy.
  • the assembly to which this variant applies covers a plurality of zones, for example four zones referenced 1, 2, 3 and 4, each supplied through a supply and grouping cabinet, without transformer. They are referenced by extension in the same way as above, 5, 6, 7 and 8, and each connected by an internal telephone interface 9, 10, 11 and 12 known under the name MODEM and by a telephone link 13, 14, 15 and 16 to a central monitoring computer 17 of a control room 18.
  • the lighting network is electrically supplied in this case by a single TRAFO transformer through a general LND distribution line.
  • Each lamp post such as 19, in each zone is equipped with an illuminating unit such as 20, for example a bulb and a transmitter module such as 21, preferably housed in its base, at the connection box, and supplied by the electrical circuit supplying the lamppost on the LAZ zone line.
  • an illuminating unit such as 20, for example a bulb and a transmitter module such as 21, preferably housed in its base, at the connection box, and supplied by the electrical circuit supplying the lamppost on the LAZ zone line.
