Definitions

  • the present invention relates to a method and a system for monitoring the failures of at least one light source, more particularly suitable for monitoring a plurality of public lighting sources.
  • Monitoring of such networks is generally carried out either at night, which is a drawback for the personnel responsible for this monitoring, or during the day by keeping the network energized, which causes additional energy expenditure.
  • the present invention aims to overcome these drawbacks.
  • the invention firstly relates to a method for monitoring the failures of at least one light source, characterized in that after the end of the service of said source, its supply network is replenished using an AC control voltage, detect the state of the source, modulate the control voltage according to the state of the source, and pick up the modulation at a point in the supply network far from the source.
  • a sufficiently low control voltage is used so that the source does not reboot, which causes only minimal energy consumption.
  • this resistor can be connected for half a period of the control voltage, the resulting modulation being picked up by integrating the current over a complete period of this control voltage.
  • connection of the resistor causes a decrease in the impedance, and therefore, an increase in the current during this half-period.
  • the modulation of the control voltage can be carried out for each source after a time, after the network is replenished, depending on a serial number of the source , after the network has been replenished.
  • the present invention also relates to a monitoring system for implementing the method described above, characterized in that it comprises individual equipment for each of the sources to be monitored, and central equipment, each individual equipment comprising : a source state sensor, and -a transmitter connected to the source supply line to modulate the control voltage, and central equipment including: a response receiver connected to the source supply line, and a memory associated with each source to store the response of this source.
  • the transmitter may in particular comprise a resistor and a switch for connecting the resistor to the supply network for half a period depending on the state of the source, the receiver comprising an integrator for integrating the current for a period.
  • each individual item of equipment includes at least one memory for storing the state of the associated source.
  • Each individual item of equipment may furthermore comprise, more particularly, a temperature sensor disposed near the source, for example a thermocouple, the thermal inertia of the sources keeping track of the operation for approximately 5 minutes after the network has been switched off.
  • a temperature sensor disposed near the source, for example a thermocouple, the thermal inertia of the sources keeping track of the operation for approximately 5 minutes after the network has been switched off.
  • each individual device When monitoring a plurality of sources, each individual device, as well as the central device, includes a counter, the transmitter of each individual device being arranged to be activated after a time, after the network has been replenished, as a function of a serial number of the source.
  • the central equipment can also include a synchro-coupler to replenish the network at a predetermined time.
  • the devices shown in the drawings allow remote signaling of individual failures of discharge lamps from a high voltage or low voltage public lighting network.
  • Each candelabra in the network has individual equipment while the central equipment is housed in the high-voltage substation of the lighting network or in the low-voltage cabinet.
  • the individual equipment of FIG. 1 comprises a sensor 1 associated with a memory for memorizing a failure of the lamp, and a sensor 2 for detecting a failure of the ballast compensation capacitor.
  • These two sensors are connected to a logic circuit 3 supplied by a supply 4 connected to the electrical supply network 5 of the lamp, placed during the candelabra test phase under an alternative control voltage at 50 Hz, but of sufficiently low amplitude. to avoid re-ignition of the lamps.
  • the logic circuit 3 includes a counter 6 which counts the positive half-waves of the control voltage applied to the network 5.
  • a memory 7 contains the number of the candelabrum associated with the individual equipment, which will be activated after a time proportional to this order number.
  • the outputs of the counter 6 and of the memory 7 are compared in a comparator 8 which makes it possible, via an AND gate 9, to validate a "YES" signal transmitter 10.
  • the other input of the AND gate 9 receives the output of an NI gate 11 at the input of which the outputs of the sensors 1 and 2 are applied.
  • the output of the gate 11 is at 1, so that, when the content of the counter 6 is equal to a predetermined multiple of the number of order contained in memory 7, the transmitter 10 sends on line 5 a "YES" signal indicating that this candelabra is in order.
  • the sensor 1 memorizing the failure of the lamp can use a thermocouple fixed on the hot part of the candelabrum, associated with an amplifier.
  • the thermal inertia of the lamps retains the trace of operation approximately 5 minutes after the network has been switched off, allowing the sensor to then supply a logic 1, in the event that the lamp has actually been lit during the immediately preceding operating time.
  • the capacitor failure sensor can use a measurement of the current absorbed by the capacitor under the control voltage to then also provide a logic 1.
  • the central equipment comprises a synchrocoupler 12 for applying the control voltage from a source 13 on one of the phases 14 of the network.
  • This control voltage is applied at a determined time in the period to achieve the best compromise between the spatio-temporal oscillations of the voltage wave and the aperiodic components of the current which are long to absorb.
  • An automaton 15 controls the switching of the synchrocoupler 12 and also makes it possible to manage the signals transmitted in response in the individual devices.
  • the automaton is connected on the one hand to a counter 16 also counting the positive half-periods of the control voltage, so as to know permanently which individual equipment and therefore which candelabrum corresponds to the received signal.
  • This signal is received by a "YES" signal receiver 17 connected to a shunt 18 transforming into voltage variations the current variations appearing in line 14.
  • This receiver 17 will be described in more detail below.
  • the automaton 15 stores in a set of one-bit memories, an indication of failure corresponding to the candelabrum whose serial number is provided by the counter 16.
  • the central equipment of FIG. 2 finally comprises a compensation choke 19 whose function will also be described below.
  • the central equipment sets up the control voltage on the network.
  • the appearance of this voltage is interpreted by the individual devices as an order to have to respond to the instant allocated to them according to their order number.
  • this control voltage serves as a time base for synchronizing the individual equipment and the central equipment which counts the positive half-waves.
  • control voltage finally plays the role of carrier amplitude modulated by the individual devices for the transmission of information.
  • FIG. 3 shows the supply line 20 to which the discharge lamp 21 of a candelabrum is connected by means of a transformer 22.
  • the lamp 21 is lit by means of a ballast 23, that is to say an inductor connected in series with the lamp, and an initiator 24.
  • a compensation capacitor 25 is connected in parallel with the lamp 21 to compensate for the reactance of the ballast 23.
  • the figure shows the individual equipment 26 comprising the aforementioned counter 6 and the logic circuits represented as a whole by 27. Furthermore, a switch 28, produced for example in the form of a thyristor, makes it possible to connect in parallel on the line supply 20 a resistor 29 when the individual equipment must send a "YES" signal. The switch 28 and the resistor 29 therefore constitute the "YES" signal transmitter 10 shown diagrammatically in FIG. 1.
  • the shunt 18 is connected to the “YES” signal receiver 17 by means of a switch 30 controlled by the counter 16 for a period, closed at regular intervals, for example every 4 periods.
  • the voltage across the shunt 18 is then integrated separately over its two half-periods, using two diodes 31 and two capacitors 32.
  • the outputs of the capacitors 32 are amplified in amplifiers 33, the outputs of which are applied to a differential amplifier 34.
  • a comparator 35 makes it possible to detect whether the output of the differential amplifier 34 is sufficiently different from zero, which means that a "YES" signal has been sent by the individual equipment of the candelabrum being tested.
  • FIG. 5 represents in its left part the case of the reception of a “YES” signal signifying that the candelabrum is in working condition, and in its right part the case of an absence of response signifying either that the candelabrum is faulty , or that the individual equipment itself with which it is associated is out of use.
  • the synchrocoupler 12 establishes the control voltage at time zero, as shown by curve 40 (it is assumed that the candelabrum tested is that of order number 1).
  • the compensation choke 19 is chosen so that the voltages Y and v at the terminals of the counters 6 and 16 are in phase, since these counters must count the periods synchronously.
  • the counters 6 of each individual item of equipment are shifted by 4 periods and each send an order S between times 1.5 and 2.5 of their phase (curve 41), to the “YES” signal transmitter 10 which, there is no fault emits a half-wave of current I (curve 42) by switching for a half-period the resistor 29.
  • the shunt 18 supplies at its terminals an image voltage of the current J in the circuit, so that at the time of reception of the signal "YES" an asymmetry of the order of 30% appears as shown at 43 of curve 44.
  • the counter 16 then gives the order to switch the image voltage of J on the integrator 17, by means of the switch 30 (curve 44).
  • the diodes 31 then charge the capacitors 32 each for a half-period, these capacitors then having the voltages A and B.
  • curve 46 we see on curve 46 that the voltage A begins to decrease at time 1 to return to zero at time 4, then that curve 47 shows that voltage B begins to increase at time 2 and also returns to zero at time 4.
  • curve 44 voltage B increases much more than decreases voltage A , so that the output ⁇ of the differential amplifier 34 (curve 48) forms an essentially positive slot.
  • Comparator 35 corrects false zero and provides a logic 1 (curve 49) when a "YES" signal is received.
  • the counter 16 sends the reading order OL (curve 50) to the automaton between time 2.5 and time 4.
  • the value of the resistance 29 is calculated for each network in order to create a current demand as large as possible having regard to the need not to disturb the voltage wave too much.
  • the voltage drop must not be greater than 50% of the control voltage at the switching point to avoid disturbing the meters.
  • the compensation chokes 19 are preferably adjustable. Indeed, the departures and each of their phases have different characteristics and, moreover, the network structures can evolve as a result of extensions or operating maneuvers.
  • Self / network tuning can be done manually by operators from time to time, or can be done automatically by the controller using information from a sensor measuring the time offset of the voltage and current zeros.
