Definitions

  • the invention relates to a drive-in control device for an elevator with a three-phase motor, which is coupled to a tachometer dynamo and whose speed can be regulated via an actuator during the run-in phase, a setpoint generator that can be switched on at the start of the run-in phase being provided, which has an integrator that has one of the tachometer dynamo The actual speed value generated is integrated and the output side is connected to a subtractor, which forms a path difference proportional to the speed setpoint from an actual path formed by the integrator and a path corresponding to the entry route.
  • a control device with a setpoint generator according to the generic term is known, for example, from CH-PS 550 736. If such control devices guaranteeing great stopping accuracy are used in elevators with three-phase motors, it is advantageous to let the phase of constant speed preceding the entrance run uncontrolled. The regulation during this phase could only consist of braking the motor to its lowest stationary speed with correspondingly high losses with every elevator load. However, difficulties arise during the transition from the unregulated to the regulated phase, since when the regulation for the entrance is used, there can be large differences between the load-dependent actual speed value and the suddenly occurring speed setpoint, which can be more or less hard impacts for the users of the elevator make it uncomfortably noticeable.
  • DE-OS 3 010 234 discloses a control device which is intended to avoid the disadvantage mentioned above.
  • a voltage-dependent cross-fader is provided, which influences the influence during a section of the driving diagram continuously changed by two independent control loops depending on the tachometer voltage.
  • One control loop controls the acceleration depending on the time, while the other control loop controls the speed depending on the path.
  • the b / t control At the beginning of the braking process, almost exclusively the b / t control is engaged.
  • their effectiveness is continuously reduced and that corresponding to the v / s control is increased, so that at the end of the braking phase the v / s control is practically exclusively engaged. This is to ensure a smooth transition when the braking phase begins and an exact entry on one floor.
  • the control device described above has a relatively complicated structure since, in addition to two b / t controllers and one v / s controller, there is also a cross-fader with at least five operational amplifiers.
  • the invention has for its object to provide a drive-in control device according to the preamble in which the difference between the actual speed and setpoint during the transition from an unregulated phase of travel to the controlled run-in phase does not come into effect and only one speed control loop is effective during the entire run-in phase .
  • the speed setpoint is adapted to the actual speed value by forming a factor from the actual speed value and an assigned nominal speed during the unregulated phase of the journey and storing it in a memory device during the braking phase.
  • Path-dependent speed setpoints are stored in a driving curve memory, which are multiplied by the factor and are supplied to a speed control loop as speed setpoints during the braking phase.
  • the advantages achieved by the invention are that when there is a transition from the unregulated phase of the journey to the regulated running-in phase, even with larger differences between the actual speed value and setpoint value, there are no impacts that impair driving comfort. Since this goal is achieved compared to the prior art with a setpoint generator improved by simple means and only one control loop, a simple, cost-saving solution to the problem mentioned at the outset results.
  • 1 denotes a three-phase motor, for example an asynchronous motor, which drives an elevator car 5 suspended on a conveyor cable 3 via a traction sheave 2 and balanced by a counterweight 4.
  • the asynchronous motor 1 is coupled to a tachometer dynamo 6, which generates a voltage proportional to the speed.
  • the elevator car 5 is guided in an elevator shaft 7, only one floor E n being shown.
  • With 8 is a magnetic switch attached to the elevator car 5, which interacts with switching magnets 9 arranged in the elevator shaft 7.
  • the switching magnets are arranged at a certain distance in front of the floors, corresponding to the entry path s o of the elevator car 5, and thus mark the point at which the brake is used.
  • the magnetic switch 8 is connected to an input of a brake application logic 10, which can be supplied with stop signals assigned to the upward or downward movement via further inputs.
  • the three-phase motor 1, the tachometer dynamo 6, a first subtractor 11, a first control amplifier 12, a second subtractor 13, a second control amplifier 14 and an actuator 15 form a speed control loop, which is subordinated to a current control loop for stabilization.
  • the first subtractor 11 is connected on the input side to a setpoint generator 16 and the tachometer dynamo 6. From a speed setpoint generated by the setpoint generator 16 and a speed actual value determined by the tachometer dynamo 6, the first subtractor 11 forms a speed control deviation ⁇ v, which is supplied to the second subtractor 13 via the first control amplifier 12 as a current setpoint.
  • the second subtractor 13 forms a current control deviation from the current setpoint and a current actual value of the three-phase motor 1, which is fed via the second control amplifier 14 to the actuator 15, which consists, for example, of thyristors controlled by adjusting the ignition angle.
  • the setpoint generator 16 has an integrator 17, which is connected on the input side to the tachometer dynamo 6 via a first contact 18.
  • the output of the integrator 17 is connected to an input of a further subtractor 19, the other input of which is supplied with a voltage corresponding to the entry path s o and the output of which is connected to the input of a driving curve memory 20 in which distance-dependent speed setpoints are stored.
  • 21 designates a divider, one input of which is connected via a second contact 22 to the tachometer dynamo 6 and the other input of which is connected to the output of the driving curve memory 20.
  • a memory device 23 is connected downstream of the divider 21 and is connected on the output side to an input of a multiplier 24, the other input of which is connected to the output of the driving curve memory 20.
  • the output of the multiplier 24 forms the output of the setpoint generator 16, which is connected to the first subtractor 11 of the speed control loop. 25 with a relay is referred to that with the output of the brake application logic 10 and a voltage source, not shown, is connected and actuates the first and second contacts 18, 22 when excited.
  • the drive-in control device is implemented by means of a microcomputer, the drive curve memory 20 and the memory device 23 are a fixed value or a read / write memory.
  • the entry control device described above works as follows:
  • the actual speed value v io depending on the elevator load, is smaller than the nominal speed value v so (time t o , FIG. 2).
