Definitions

  • the present invention relates to a device for control and monitoring remotely from a plurality of discharge lamps.
  • discharge lamps have a certain lifespan. So you have to replace regularly, which poses some problems in the case of public lighting.
  • a lighting maintenance team that regularly runs a campaign test consisting of lighting the candelabras during the day so that you can be sure visually of the correct functioning of the lamps, and possibly to replace faulty lamps.
  • these campaigns must be carried out frequently.
  • this device is characterized in that the central station comprises an interface circuit connected to the electrical distribution network and which ensures exchange of information between the central station and the distribution network electric, and in that the transmission and reception means of each module are designed to receive all messages conveyed by the power line, and re-issue at least some of the messages which are not intended for them.
  • each candelabrum is controlled and monitored independently of the others, in real time and directly from the central station, without the need to provide a telephone link between each electrical distribution cabinet and central station.
  • each module of control and monitoring can therefore play the role of repeater.
  • each candelabrum is generally nearby (a few tens of meters) another candelabrum, this ensures the transmission of messages from the transmitter to the recipient thereof, regardless of the distance between them, and despite the short range of carrier current transmission.
  • each control and monitoring module includes means for controlling the light intensity of the lamp as a function of instructions issued by the central station.
  • each control and monitoring includes means for detecting the deterioration of the state of lamp operation.
  • each control and monitoring includes means for counting the operating time of the lamp.
  • Figure 1 shows a substation 1 for transform the electricity into high voltage that it receives, three-phase low voltage (220 V), to supply a set 2.6 electrical distribution cabinets, including distribution cabinets 6 assigned to public lighting.
  • Each distribution cabinet 6 for lighting receives in input the three-phase low voltage electric current, and supplies a set of low power lines 7 single-phase voltage.
  • Each of these lines 7 comprises two 15.16 wires for powering a plurality of lamps discharge 11 each associated with a control device and monitoring 10 according to the invention.
  • the device 10 is designed to transmit and receive information by carrier current, in phase modulation, for example at a frequency of 132 kHz, via the network of electrical distribution, to communicate with a substation central 3 connected to another distribution cabinet 2.
  • the central station is equipped with a computer 5, connected to the electrical network via an interface module 4 which ensures the exchange information between the computer 5 and the network electric.
  • the control and monitoring device 10 is connected to the two wires, phase 15 and neutral 16 of an electric line, the neutral being also connected to one of the terminals of the discharge lamp 11.
  • a starting circuit 13 connected in parallel with the lamp 11 is used in a known manner, and a ballast 14 with high self-impedance applying a supply voltage supplied by the device 10 to the lamp 11 and to the ignition circuit 13, the ballast 14 having the purpose of limiting the current passing through the lamp 11 when the latter is on.
  • ballast 14 When the lamp 11 is off, no current flows there crosses.
  • the voltage applied to the input of ballast 14 is then transferred to the priming circuit 13 which allows to apply to the terminals of the lamp 11 a pulse of voltage (of the order of 2000 V) above the ignition threshold of the lamp, causing the lamp 11 to light up, and therefore the passage of current in the latter. Once that the lamp 11 is on, the lamp then being supplied than via ballast 14.
  • ballast 14 As the impedance of ballast 14 is strongly self-inductive, it it is imperative to have a capacitor 12 in parallel correcting the phi cosine.
  • a starting pulse generator is associated with the lamp 11 and ballast 14 assembly.
  • the coupling circuit 22 can be produced using a transformer or resonant LC type circuit on the frequency of the transmission carrier of carrier current messages.
  • the second stage, or output stage comprises, in series between phase 15 and ballast 14, an inductor Z1, followed by two switches K1, K2 in series.
  • the first switch K1, of the relay or triac type is controlled by the microprocessor 23, from the synchronization signal SS supplied by the synchronization circuit 27, and is intended to apply the voltage Us supplied by the network to the discharge lamp 11, and in particular to the correction capacitor 12 connected to the junction point between the two switches K1, K2.
  • the load then being capacitive, the command of K1 is applied to the zero crossing of the voltage Us of the network.
  • the second switch K2 of the thyristor or triac type, is intended to power the lamp there via the ballast 14. It is controlled by a logic signal CK2 from a comparator 30. It is also connected to neutral 16 via a capacitive impedance Z3 intended to establish a current Iz when the lamp 11 is absent or broken down.
  • lamp synchronization In parallel with the second switch K2, there is a second synchronization circuit Z2, called lamp synchronization, which provides a logic signal from lamp synchronization SL to 0 when switch K2 is open, and to 1 when the latter is closed.
  • Mains synchronization circuits 27 and lamp Z2 can be made using photo-couplers so to ensure good electrical insulation between the second and third floors.
  • the microprocessor 23 is connected to two LEDs, a red LED 31 for signaling faults, and a green light 32 for signaling the states of operation. It is also connected to a button 33 of on / off, and a button 34 which allows, when changing of lamp 11, triggering transmission an initialization signal to the central station 3, indicating the effective replacement of the lamp 11, and allowing the reset of a usage time counter of the lamp 11.
  • the microprocessor 23 communicates with central station 3 by messages transmitted by carrier current, in phase modulation, for example at a 132 kHz frequency, via the distribution network electric.
  • each lamp 11 controlled by the central station 3 is identified by an identification code which is inserted in each message exchanged with the post central.
  • Curve C1 shows that the voltage Us between phase 15 and neutral 16, or the voltage Uc at the junction point between the two switches K1, K2, has a shape sinusoidal.
  • Curve C2 shows the shape of the logic signal sector synchronization SS from circuit 27, which changes logic state whenever the line voltage They cancel each other out.
  • the microprocessor 23 controls switch K1 when switching to zero of the mains voltage Us, thanks to the synchronization signal SS sector shown by curve C2. Detection of a voltage UK2 at the terminals of switch K2 by the lamp synchronization circuit Z2 results in release of the integrator 28.
  • the comparator 30 delivers a control voltage CK2 which allows the ignition of switch K2.
  • Switch K2 is controlled at its turn with a set point at zero, implying an opening angle 41 void. As the charge of K2 is selfic, the current IB crossing it is therefore late by a certain phase shift 42 with respect to the voltage Uc (curve C4).
  • the lamp synchronization circuit Z2 delivers a signal logic SL to 1 whenever absolute value of the UK2 voltage across switch K2 exceeds threshold 45, i.e., during periods when switch K2 is blocked (curve C6).
  • This logic signal SL is sent to microprocessor 23, and is applied as input to the integrator 28 which delivers a sawtooth signal which remains zero when the lamp synchronization signal SL is at logic level 0 (curve C7).
  • the microprocessor 23 can impose a setpoint in the form of binary data applied to the input of the analog / digital converter 29. If this setpoint data is not zero, we get at the output of comparator 30, a logic signal at 1 when the signal in integrator output exceeds threshold 46 defined by this setpoint, and zero otherwise, the signal CK2 from comparator 30 used to control the switch K2 (curve C8).
  • Curves C9 to C13 illustrate the detection of lamp stalls.
  • the stall or a breakdown of the lamp results in the absence of current IB at the input of the ballast 14.
  • the load is then solely determined by the impedance Z3 placed between the switch K2 and the neutral 16, this load being insufficient to maintain switch K2 in the on state.
  • the capacitive impedance Z3 is then crossed by a current Iz in phase advance 43, and practically in phase quadrature with the voltage Uc at the input of the switch K2 (curve C9).
  • the resistive impedance of Z2 and the capacitive impedance of Z3 then form a voltage divider bridge so that the resulting voltage UK2 across the terminals of switch K2 is less than the trigger voltage threshold 45 of the latter (curve C10 ).
  • the detection threshold 44 of the synchronization circuit lamp Z2 being far below the trigger threshold 45 of switch K2, the lamp synchronization signal SL is therefore at logical level 1 in the vicinity of each passage at zero of the mains voltage Us (curve C11).
  • Curve C12 shows the signal SI at the output of the integrator 28, obtained from the lamp synchronization signal SL showing the shape of curve C11.
  • Curve C13 shows the form of the switch command signal CK2 K2, which is at logic level 1 when curve C12 exceeds setpoint 46.
  • the UK2 voltage across the K2 switch is below the trigger threshold 45 of it it therefore remains blocked regardless of the command given to it applied.
  • the microprocessor 23 can determine whether the lamp 11 is off or on by comparing synchronization signals SS sector and SL lamp. If at the moments of the fronts amounts and / or descendants of the SS signal correspond to moments when the SL signal is zero (curves 2 and 6), the lamp is detected on. Otherwise (curves 2 and 11) the lamp is detected off.
  • each control and monitoring device 10 has instructions variables that can change depending on the state of the lamp he controls. This state is determined during reduction regime: if microprocessor 23 realizes that during the reduction in lighting intensity, the lamp goes off, then it decreases the reduction rate planned.
  • the microprocessor 23 advantageously has 7 reduction rate, and when it reaches an alert rate predetermined, it warns central station 3 of the degradation of the lamp 11.
  • the microprocessor 23 is further designed to declare in a lamp 11 which no longer tolerates reduction or which can no longer prime at maximum voltage. In practice a delay of a few minutes is left to the ignition circuit 13 before declaring the lamp 11 in failure and notify the central station 3.
  • the operator activates the button 34, allowing on the one hand to warn the post central 3 of the lamp change, and on the other hand reset variable parameters such as the rate of reduction of lamp lighting.
  • the computer 5 of the central station 3 can count the operating time of each lamp, and compare this duration to an alert threshold, the crossing of this threshold indicating that the lamp is to be replaced.
  • the central station 3 can thus draw up a list of lamps with replace by grouping the overrun information this alert threshold, for lamp degradation detection, and lamp failed, in order to prepare and trigger the replacement interventions, when the lamps to be replaced are in sufficient number. We can thus group interventions to reduce the unit cost, the maintenance team being warned of changes in lamps to provide before they are really out of order.
  • the transmit / receive circuit 25 shown in FIG. 3 is a phase modulation modulator / demodulator, of the synchronized asynchronous type, comprising for example, a first EXCLUSIVE OR gate 53 which combines a carrier F t with the signal of the data to be sent from the connection terminal T x of the microprocessor 23, and delivers a signal modulated in phase or in phase opposition with the carrier as a function of the logic level 0 or 1 of the data to be sent.
  • a phase modulation modulator / demodulator of the synchronized asynchronous type, comprising for example, a first EXCLUSIVE OR gate 53 which combines a carrier F t with the signal of the data to be sent from the connection terminal T x of the microprocessor 23, and delivers a signal modulated in phase or in phase opposition with the carrier as a function of the logic level 0 or 1 of the data to be sent.
  • the output of gate 53 is connected to coupling circuit 22 which is either positioned in transmission or in reception thanks to a signal T x R x transmitted by the microprocessor 23 and applied to the E / R input of coupling circuit 22.
  • the coupling circuit 22 When the coupling circuit 22 is positioned in transmission, it has a low output impedance, of the order of a few Ohms. It also makes it possible to filter the signal emitted to transform it into a sinusoidal signal.
  • the pulse generator 56 delivers a signal d (F t ) consisting of one pulse at each edge of the input signal F t , that is to say, two pulses per period of the signal F t .
  • the switch 60 is open between two pulses of the signal d (F t )
  • the voltage across the capacitor C d remains blocked at logic level 0 or 1 of the last value of the voltage sampled by the switch 60 when the latter it was closed during a pulse supplied by the generator 56.
  • the signal T x R x also serves to control a switch 57 which makes it possible to select either the data signal F x received by the coupling circuit 22, or a signal F 0 generated by an oscillator 58, preferably controlled by a quartz.
  • This signal F 0 has a periodic rectangular voltage having a constant frequency, equal to that of the carrier.
  • the signal F 0 or F x selected by the switch 57 is sent to the input of the EXCLUSIVE OR gate 52.
  • the control loop thus makes it possible to calibrate the frequency and the phase of the signal F t delivered by the oscillator 54, on transmission, on those of the signal F 0 , and on reception, on those of the received signal F x .
  • the switch 57 is positioned by the signal T x R x so as to apply the output signal F 0 of the oscillator 58 to an input of the gate 52.
  • the signal F 0 being constant
  • the signal F t generated by the oscillator 54 is also constant, as is the signal d (F t ) generated by the pulse generator 6 and which controls the switch 10.
  • the signal passing through the switch 60 charges the capacitor C d at logic level 0 or 1, which blocks the voltage across the capacitor at logic level 0 or 1 from the last sample taken to the next sample.
  • the filter 62 makes it possible to obtain a voltage U 0 for controlling the oscillator 54 so that the signal F t corresponds in frequency to the signal F 0 .
  • the signal T x emitted by the microprocessor 23 begins with a start bit to allow the recipient of this signal to remove the uncertainty on the initial phase of the signal. On reception, the value of this start bit can be used to determine whether or not to reverse the value of the following bits contained in the received signal.
  • the coupling circuit 22 On reception, the coupling circuit 22 is positioned on reception by the signal T x R x , it then has a high input impedance, of the order of a few hundred Ohms, so as to transmit the data signal F x from the electrical network to an amplifier 59 which also performs a filtering of the parasitic frequencies circulating on the electrical distribution network.
  • the switch 7 is positioned by the signal T x R x so as to apply the signal Fx to the input of the gate 52.
  • the EXCLUSIVE OR gate 52 then combines the carrier with the received signal F x , to obtain a signal F t + F x at logic level 0 or 1 depending on whether the received signal F x is in phase or in phase opposition with the carrier F t , the signal F t + F x being introduced into the control loop described above.
  • the sampler-blocker constituted by the generator 56 which controls the switch 60, as well as the capacitor C d makes it possible to reset the received signal F x at constant phase with respect to the frequency F t , and supplies the microprocessor 23 with the demodulated signal U d available across the capacitor C d .
  • This demodulated signal is applied via an inverter 63, on the one hand to the input R x of the data received from the microprocessor 23, and on the other hand to the input P for detecting the carrier of the microprocessor 23 , through a pulse generator 64 and a time constant circuit 65. In this way, the microprocessor 23 can determine whether it should wait for reception of a message in the event of detection of the carrier on its R x input, and if it can send a message in the absence of a carrier.
  • this circuit can send and receive a signal digital at the speed of 90 Kilo-bits per second.
  • the microprocessor 23 receives all messages detected by the coupling circuits 22 and reception 25, and control re-transmission of messages which are not intended for it. This solution allows to control and monitor a large number of candelabras, thanks to the demodulation principle which achieves transmission speeds high.
