Definitions

  • the present invention relates to the field of cable transport installations.
  • the invention relates, more particularly, to transport installations comprising at least one towing cable to which the vehicles are coupled in order to be towed.
  • Some of these installations use one or more overhead hauling cables, such as cable cars, funitels and DMCs, 3 S, chairlifts or even teleports with seats and cabins.
  • Other installations use one or more hauling cables attached to vehicles running on a railway track, either overhead or on the ground, such as funiculars.
  • These transport installations allow the movement of one or more vehicles. These vehicles make it possible to transport passengers and/or materials between several locations. These vehicles are also called cabins, skips or seats.
  • oscillations of the cable which take the form of a predominantly vertical movement coupled with longitudinal oscillations, are likely to be triggered locally between two intermediate pylons.
  • the oscillations of the cable can be coupled with the pendulum movement of the vehicles attached to it.
  • the person skilled in the art refers to this phenomenon as pumping.
  • the person skilled in the art therefore seeks to avoid triggering the pumping phenomenon on cable transport lines by applying empirical criteria in force in the profession, both in an anticipatory manner when designing the installations, and in a corrective manner when the phenomenon appears on an installation already in operation.
  • the determination of the design parameters of a cable transmission line that allow to avoid pumping can be seen as the result of a problem of optimization under constraints, resulting from the formulation of a mechanical model of the complete system in dynamics.
  • the complexity of such a model requires the implementation of resolution methods specific whose developments are still open subjects of investigation.
  • a strategy of active control and damping of oscillations is a possible response to the pumping problem.
  • THE patent document FR 3108185 proposes a method for controlling a vehicle transport installation by a continuously moving cable based on a device that adapts the speed, voltage and distance parameters between vehicles to avoid operating points of the system likely to trigger pumping.
  • the method described can be considered active in the sense that measurements are carried out in real time on the installation, to detect the triggering of an oscillation on the cable, and that the operating parameters are modified automatically according to a learning device.
  • the device does not act in a direct and targeted manner on the oscillation, which occurs locally on the cable loop, but globally via the drive system and the associated control-command.
  • Pumping is mainly manifested by a vertical oscillation, coupled with a longitudinal oscillation of the mobile cable, in a localized manner at one or more spans separated by adjacent intermediate supports. Pumping causes oscillations of the longitudinal speed of travel of the cable on the supports relative to the nominal drive speed imposed by the drive pulley.
  • the mobile cable rests on supports consisting of a set of rollers, pulleys of small diameter less than a meter, independent, uncontrolled and free to rotate.
  • the rotational movement of the rollers is imposed by the longitudinal dynamic movement of the mobile cable.
  • the present invention aims to overcome at least one of the aforementioned drawbacks and to further lead to other advantages by proposing a new type of method for controlling line oscillations of a cable transport installation.
  • Another aim of the invention is to improve the comfort of passengers as well as their safety during their travel by means of the vehicle transport installation using at least one mobile cable.
  • the invention thus allows direct control of the rotation speed of one or more support rollers, forming part of an assembly designated by a balance or shoe, in contact with the mobile cable and positioned on the intermediate supports of the line, also designated by pylons.
  • the invention consists of an active damper of the oscillations of the cable by acting directly on the longitudinal dynamic movement of the cable at the level of the supports of the intermediate supports.
  • the signal giving an image of the translation speed of the mobile cable on the installation line is generated by a rotation speed sensor, of the tachometric type, connected to the rotation axis of the roller which is free.
  • the signal giving an image of the translation speed of the mobile cable to the drive pulley is generated by a measuring roller, in contact with the drive pulley and connected to a tachometric sensor in connection with the axis of rotation of the measuring roller.
  • the comparison between the speed signals from the support roller of the intermediate support and the drive pulley is carried out by considering the absolute value of the difference between the values of the signals. Filtering can be applied to the signal thus obtained in order to reduce, increase or eliminate certain parts of the spectral content for the proper functioning of the control method.
  • the correction step consists of a PID type regulator whose output signal acts on the running speed of the cable at the intermediate support roller, by means of the control of the rotation speed of the support roller by a dedicated control device.
  • control device used during the correction step is integrated into a control loop regulated by a proportional, derivative, integral action by a PID type corrector. acting on the quantity resulting from the comparison step between a setpoint signal, provided by the measurement of the speed of the cable at the drive pulley, and a measurement at the output of the control device of the rotation of the support roller, provided by the measurement of the speed of the cable at the support roller.
  • the comparison step between the setpoint signal and the measurement then constitutes the feedback of the closed-loop servocontrol and thus capable of autonomously developing the control quantity sent to the control device so that the controlled quantity, the translation speed of the cable at the support roller, can reach the setpoint value, the translation speed of the cable at the drive pulley, quickly, stably, precisely and robustly.
