Definitions

  • the invention relates to a method and a device for controlling the operating condition of an overhead cable transport installation driven by an electric motor and capable of transporting vehicles of variable load along a line of transportation. displacement extending between two stations, in which installation the instantaneous power of cable drive is measured and reduced by a signal.
  • the tractor or carrier-tractor cable is driven by a power station and the movement is transmitted by the cable over a trajectory of several hundred meters or even over kilometers of which surveillance over the entire route is practically impossible.
  • User safety nevertheless requires instant detection of any incident at any point in the installation, and detectors are known for cable derailment or untimely movement of the cable tension counterweight.
  • the derailment detectors must be placed in line with each cable guide pulley and be connected by an electrical safety line extending along the installation, while the operation of the detector associated with the counterweight is unreliable.
  • the present invention aims to remedy these inconveniences. come by carrying out a permanent control of the operation of the installation. It starts from the observation that the driving power of the cable at a given time is a function of the speed of the cable, the slope of the cable at the location of the vehicle (s) along the line, the load carried by the or vehicles and the condition of the facility. By determining the first three parameters, it is therefore possible to check the operating status of the installation.
  • the method according to the invention is characterized in that the line data is recorded in a memory unit for the evaluation of the normal drive power of the cable as a function of the value of the load transported, of the position of the line vehicles and cable speed, which is provided to a central processing unit for data on cable drive speed, line vehicle load value and position of line vehicles at each instant, said central unit interrogating the memory unit to generate from said data a signal representative of said normal power and that said normal power and instantaneous power signals are continuously compared in a comparison block to develop a representative output signal the difference between said powers, said output signal triggering an alarm and / or a device for stopping the installation when a predetermined threshold is crossed completed.
  • the position of the vehicle is given by the movement of the winch of the towing cable and it suffices to record the profile of the line and read this recording during the movement of the vehicle to have the data of calculation of normal power, if care is taken to count or weigh the passengers on board.
  • the memory unit and the central processing unit can be very simple and produced by any suitable means. If the cable car has two skips, calculate the normal power for each skip and deduct the resulting total normal power.
  • the control device receives the starting information at each clutch of a cabin in one or the other of the stations, at the same time as the information of the load. transported.
  • the control device is advantageously in this case a computer, which tracks each cabin during its online movement and knowing at all times the different positions of the cabins, their loads, the speed of the gondola and the profile of the line, can calculate or determine the normal drive power of the cable.
  • a simple comparator for example a differential amplifier and a threshold circuit, allows signaling of a notable difference between instantaneous and normal powers. Abnormal advancement resistance can thus be detected before the incident or accident and allows preventive intervention.
  • a cable car comprises a motor 10 for driving the winch of the towing cable 12 of a bucket 14 circulating between the two stations A and B.
  • a scale 16 weighs the passengers embarking in the bucket 14 and provides a signal P of the total weight of the bucket 14 to a central processing unit 18 of a control device designated by the general reference 20.
  • a tachometer generator 22 coupled to the motor 10 supplies this central unit 18 with a signal V of the speed of the cable 12.
  • the motor 10 drives by a transmission 24 a magnetic recording tape 26 with read heads 28, 30.
  • the tape 26 moves in synchronism with the bucket 14 and the read heads 28, 30 read the recorded information corresponding to the location of the bucket online.
  • One of the recording tracks of the tape 26 can represent the profile of the line, in this case the abscissas and ordinates of the ends of the staff, while the other track can represent correction factors, in particular at the start and braking of the bucket, as well as an increase in friction when passing a pylon.
  • the central unit 18 permanently has the stored information read by the heads 28, 30 and the speed and load information and this data is transmitted to a calculation unit 32 which determines the normal drive power of the cable 12.
  • the signal of calculated normal power is supplied to a comparator 34 which receives an instantaneous power signal emitted by a measuring device 36 of the electric power W supplied to the motor 10.
  • the comparator 34 indicates the difference between these two powers and triggers an alarm or stops the installation if this difference exceeds a predetermined threshold.
  • the device control can be simplified if the load transported is substantially constant and if the installation operates at one or two predetermined speeds. It is then possible to store directly on the tape 26 the normal drive power for each of the speeds and to read the information corresponding to the selected speed, the control device being limited to the comparator 34. It is clear that the speed signal can be calculated by the central unit, which may include a clock, on the basis of a movement signal of the strip 26 and that the load of the cabin can be determined in a different way.
  • FIG. 2 shows an example of variation of the power as a function of the location of the bucket 14 on the line.
  • the power difference can be permanent or at a given location which makes it possible to locate the anomaly.
  • a scale (not shown) at the station B supplies the load signal P and the control device 20 receives slope change information.
  • the cabins 38 are disengaged from the carrier-tractor cable 40 in the stations and run on transfer rails 42. At the outlet, the cabins 38 are engaged on the cable 40, which is permanently driven by a driving pulley 44 coupled to a motor. electric 46.
  • the clutch of a cabin 38 is signaled by a through contact 48, which sends a start signal to a central unit 50 of a control computer 52.
  • a scale 54 weighs the people embarking in the cabin and the corresponding signal P is transmitted to the central unit 50.
  • This unit 50 also receives a displacement signal emitted by a pulse wheel 56 coupled to the driving pulley 44.
  • the computer 52 includes a memory 58 in which are recorded the characteristics of the line, in particular the online profile and a unit of calculation 60, the time base being provided by a clock.
  • the computer 52 emits a normal power signal transmitted to a comparator 62, which compares this signal with an instantaneous power signal W supplied by a Wattmeter 64 for measuring the electric power W supplying the motor 46.
