Definitions

  • the present invention relates to a traffic control device by controlling traffic lights.
  • a controlled intersection traditionally includes at least four traffic lights, to each of which are optionally associated one or more crossing tolerance arrows and pedestrian lights. These different light signals are piloted, at least at the intersection level, by a traffic controller comprising a signal management and control unit, advantageously with digital technology, controlling the switching on and off phases of the different signals. light according to given timing sequences, possibly modulated by traffic detection devices or by a central control unit.
  • the known traffic controllers a functional block diagram of which has been represented in FIG.
  • each subset si (corresponding to a traffic light), is itself subdivided into three triple units ⁇ i ;, ⁇ i and ⁇ , each unit ⁇ i ; ensuring the electronic switching of the mains voltage across a lamp A ij of the traffic light F; corresponding, each unit ⁇ i ; ensuring the synchronization of the control signals of the electronic switch of ⁇ i ; on the mains voltage, and each unit y; ensuring! the detection and the formatting of the return information necessary for the treatment of operating anomalies of the light units A i .
  • the distribution terminal block 3 supplied by the sector also supports all the protection modules.
  • Certain recent systems provide for the control of traffic lights by a power unit associated with a modular microprocessor managing the various signals.
  • these systems include power and switching modules for each group of lights, which allows no flexibility and adaptability to the particular case.
  • the object of the present invention is precisely to propose a highly integrated traffic control device, allowing optimization of the connection between the control assemblies and the controlled assemblies, and allowing a considerable reduction in the size of the device and in costs, as well as an increase in the electrical and physical isolation between the control electronics and the switched loads, on the basis of a modularity allowing flexible and reliable use of the number of power modules corresponding exactly to the number of light signals to be controlled.
  • a power module incorporating the associated switching means is connected to each light signal actually used.
  • Each power module is connected on the one hand directly to a common power supply circuit and on the other hand to determined terminals of the management unit corresponding to said light signal.
  • Each module is therefore autonomous and independent.
  • each geometrically defined and optimized power module the two main functions constituting traffic control are integrated, namely the switching and operational control of lights or light signals and the connection ensuring the supply of power of light signals and associated control circuits.
  • the marked separation between the management unit with microprocessor programmable in situ or controlled and the power modules also allows, from standard elements, to adapt simply and effectively to the different possible configurations for a crossroads, using the strict number of elements necessary depending on the number of light signals, independently of their proper function in the crossroads, as well as optionally piloting the controllers of different crossroads by a central management and control unit via the peripheral crossroads management unit.
  • the traffic control device comprises a signal management and control unit 10, with programmable microprocessor, having a series of pairs of output terminals b; each assigned to the control of a light signal A (three-color lights, arrow or pedestrian signal).
  • each light signal A is associated with a power module M i , connected, on the one hand, to the corresponding pair of terminals b; of the unit 10, and on the other hand, to two pairs of power supply bus lines 11 and 12.
  • Each power module M comprises a printed circuit board 25 comprising two pairs of connection pins 13, 14 to the pairs of bus lines 11 and 12, and a pair 15 of microcurrent connection lines for connection to the pair of terminals b; of the management and control unit card 10, as well as a pair of wire clamp output terminals 16 and 17, for connection to the associated lamp A and a ground terminal 24.
  • the link 15 between the management unit 10 and each module M transmits two pieces of information, namely a signal E, generated by the management unit 10, controlling the establishment of the mains voltage at the terminals of the lamp A, and a signal S of validation confirming or invalidating the effect of the signal E for the control of the lamp A.
  • the signal E controls the synchronous triggering, that is to say at zero crossing, of the mains current of a static switch 18, typically comprising a TRIAC coupled to a diode bridge, controlling the supply of the lamp A.
  • the isolation between the control signal E coming from the management unit 10 and the static switch 18 is ensured by an opto coupler -electronics 19 and its associated control and bias circuit 20.
  • the signal S is transmitted to the management unit 10 via another opto-electronic coupler 21 and its associated control and bias circuit 22.
  • a fuse 2 3 is advantageously provided, in the module M, between the lamp A and the static switch 18 to ensure current protection of the controlled circuit of the lamp, a varistor in parallel 50 ensuring the protection of the module.
  • the circuit of FIG. 3 is carried out according to the technique of printed circuits on a module card 25.
  • the pairs of bus lines 11 and 12 are arranged in a bussupport sub-assembly 26, ensuring the transmission of power from the sector to the modules M, and also serving to support the latter.
  • the bus-support sub-assembly 26 comprises a support profile 27 made of extruded aluminum defining two parallel and distant grooves 28 and 29, opening onto the same face of the profile, these grooves being separated by two projecting wings from the profile defining, between them, a central groove 30 with facing walls striated at a standard pitch to receive by screwing one end of the screw rod, the groove 30 also opening onto the same face of the profile 27
  • a sheathing profile of insulating plastic material 31 itself defining two longitudinal grooves 32 and 33, opening into the access groove to the associated groove 28 or 29 to the profile 28.
  • connection bars including the longitudinal bus bars 11 and 12, and a series of elastic tabs transverse to the bars for the electrical
  • each module M comprises a housing 34, of extruded aluminum of rectangular section, defining an internal housing 35 for the equipped card 25 and having, for this purpose, at least one pair of guide rails 36 and for holding the cards 25, as well as, in a side wall, an orifice 37 for the passage of a card fixing screw 25, in cooperation with a screw hole 38 on a tab attached to the card 25.
  • the housing 34 also serving as a heat sink for the TRIAC of the switch 18, also includes, in the internal cavity 35, a longitudinal barrel 39 for guiding the fixing screw 40 intended to be screwed into the grooved groove 30 of the profile 27.
  • each module M further comprises, advantageously, an operating indicator 45 constituted for example by a light-emitting diode, signaling the presence of the mains voltage at the terminals of the associated lamp A.
