Definitions

  • the present invention relates to regulating devices, in general, and relates, more particularly, to a device and a method for regulating a guided means of transport.
  • the state-of-the-art regulation devices and methods of a guided means of transport make use of centralized supervision means.
  • These centralized supervision means have in memory all the timetables of the vehicles in the network and provide a regulation order to each of the vehicles in the network.
  • a major drawback of prior art regulation devices and methods is that if a disturbance, due to the driver, passengers or other trains, occurs between the reception of the regulation order and the arrival in the next station, schedules are no longer respected.
  • Another disadvantage of the devices and methods for regulating the state of the art is that they are not very precise because they make it possible to follow a limited number of speed instructions, namely: a slow speed, corresponding to a step slow vehicle, a reduced speed, corresponding to a reduced running of the vehicle and a fast speed, corresponding to a fast running of the vehicle.
  • An object of the invention is therefore a device and a method for regulating a guided means of transport, making it possible to respect the arrival times at stations.
  • Another object of the invention is a device and a method for regulating a guided means of transport which does not have the drawbacks of the methods of the prior art.
  • the device for regulating a guided means of transport comprises control means, each of these means defining a control point P i .
  • the method of regulating a guided means of transport is such that the regulation is obtained by slaving the schedule of said means of transport.
  • Transport vehicles for example a metro or a tram, are controlled between stations by means of a central control unit allowing the vehicle to arrive at a station at a given time.
  • the central regulation unit uses two extreme reference steps called tight step 6 and relaxed step 7.
  • Stretched walking 6 corresponds to the shortest travel time and relaxed walking 7 corresponds to the longest travel time.
  • This figure 1 therefore represents speed curves V as a function of the route I of the means of transport and more particularly an example of two extreme reference steps used by the method of regulating a guided means of transport, in accordance with invention.
  • the regulating method of the invention is a regulating method by time control.
  • This regulation method of the invention complements the central regulation method of the state of the art.
  • the two extreme reference steps are predefined steps or calculated in real time.
  • the method of regulation by slaving of schedules of the invention has knowledge only of the timetables of the vehicle that it is capable of regulating.
  • the method of regulating a guided means of transport is such that the step 8A or 8B of the means of transport is controlled relative to several steps precalculated according to a schedule to be observed.
  • the precomputed steps consist only of the two extreme reference steps 6 and 7.
  • the two extreme reference steps 6 and 7 are supplemented by at least one other intermediate reference step.
  • the implementation of the time-controlled regulation method of the invention is obtained by means of control points P i distributed along the predefined path of the means of transport.
  • the method of regulation by slaving of schedules of the invention calculates the speed setpoint V c by applying a difference / time coefficient ⁇ to the setpoints of speed for tight or relaxed walking.
  • the travel time remaining in relaxed mode T rmd and the travel time remaining in tight mode T rmt are pre- calculated values. These values are contained in control means defining the control points P i .
  • the control means are constituted, for example, by ground beacons known from the state of the art.
  • control points P i defined by the control means describe the relaxed walking and the tight walking of the vehicle.
  • the difference / time coefficient ⁇ is calculated after each passage on a control point P i .
  • the step 8A of the means of transport represented in FIG. 1 corresponds to a regulation for which the difference / time coefficient ⁇ is equal, for example, to 0.5. This value corresponds to a step for which there is no disturbance.
  • the step 8B of the means of transport represented in FIG. 1 corresponds to a regulation for which the difference / time coefficient ⁇ oscillates between the values 0 and 1.
  • This regulation corresponds to a step for which a disturbance P occurs, for example between the point P 2 and the P 3 check point.
  • step 8B of the means of transport that, following the disturbance P, the regulation process imposes a difference / time coefficient ⁇ close to the value 1 and therefore a set speed V c close to the speed in tight operation of so as to allow the means of transport to catch up on the schedule and arrive at station S, unless there is an exceptional disruption, at the set schedule.
  • Each control point P i is associated with information relating to the position of the control point P i , at the distance separating the control point P i at the next control point P i + 1 , at the time remaining to cover the distance separating the control point P i at the next station and at the speed, called target speed, the vehicle must have at the next check point P i + 1 .
  • control points P i too close together in order to allow the calculations to be carried out before the vehicle passes over the following control point P i + 1 .
  • the running of the vehicle defined by means of the time-controlled regulation method of the invention is included in the steps defined by means of the central regulation process and corresponding to the markets of extreme references, namely walking. relaxed and walking tense.
  • FIG. 2 represents an algorithm of a finite state automaton allowing the implementation of the regulation method according to the invention.
  • This figure 2 shows five states 1 to 5 of the PLC, only one of these states can be active at any given time.
  • Each state is identified by one of the numbers 1 to 5, the state of the outputs and the actions carried out are also indicated.
  • the state noted 1 is the initialization state and is active when the PLC is activated.
  • transitions are noted between two successive states and indicate the event involving the change of state.
