Definitions

  • Conventional elevators enable the elevator connected to the rope to move up and down by rotating the electric motor from the power converter and moving the rope up and down via a sheave connected to the electric motor.
  • the elevator stops When a part of the drive system such as the power converter, the electric motor, or the encoder connected to the electric motor breaks down, the elevator stops.
  • the position where the elevator car stops is between the floors. If the passenger is in the car at this time, a state where the passenger is confined in the car occurs. Since the car does not move in this state, the safety of the passenger is ensured, but the passenger is uncomfortable.
  • the platform can be dismounted by unbalanced weight of the car and the counterweight while generating braking force by the brake device.
  • FIG. 1 is a block diagram illustrating the overall configuration of the elevator according to the embodiment.
  • the movement of the elevator car 104 is controlled by the elevator controller 100.
  • the elevator controller 100 includes a braking force control unit 20 in addition to the elevator control unit 2 that performs elevator operation control.
  • the brake current command creation processing unit 32 creates a brake current command based on the rescue operation start command output from the rescue operation start detection processing unit 30, and outputs the created brake current command to the brake current control circuit 21. Further, the brake current command creation processing unit 32 changes the brake current command based on the car speed output from the car speed detection processing unit 31.
  • adjustment parameters that differ depending on the type of brake are obtained from the model information database (DB) 33. Specifically, the adjustment parameter includes a time for stopping the increase of the current command value for a certain period of time after increasing the constant value current in order to wait for a change in magnetic flux.
  • the current command value is increased for a certain period of time after increasing the constant current to wait for the change in the magnetic flux. Allow time to stop the ascent. Since the change in the current command value and the delay in the magnetic flux change depend on the structure and size of the brake, this information is obtained from the model information database (DB).
  • DB model information database
  • the brake current command i * is increased stepwise, and the brake current i flowing through the solenoid coil is increased accordingly.
  • the purpose of increasing the brake current command i * (or brake current i) is to increase the brake current i to weaken the brake torque T, which is the braking force of the brake, and to generate torque generated from the balance of the car and the counterweight. And the braking force of the brake is in an equilibrium state.
  • the brake current i increases, an electromagnetic force is generated in the solenoid coil, and the brake torque T is weakened. In this state, the brake torque T is caused by the balance of the car and the balance weight. Since the car is larger than the torque, the car does not move and the car speed V remains zero.
  • the command is stepped at this time because the response of the brake is taken into consideration.
  • an actuator such as the brake device 102 is composed of an iron core and a coil.
  • the brake device 102 which is an actuator, operates in the opening direction. For this reason, as shown in the section (b) of FIG. 3, after the constant value current is increased in order to wait for the change of the magnetic flux, the increase of the current is stopped for a certain time. The time for stopping the current rise is about the same as or longer than the delay time of the magnetic flux change with respect to the current change. Thereby, it becomes possible to easily follow the current command.
  • the section (c) is the timing from when the brake current command i * is raised, the car moves and the car speed V is detected. As described above, since there is a response delay of the change in magnetic flux with respect to the change in the current command, there is a time until the brake torque T changes and the car speed V is detected as in this section (c).
  • the section (d) shows a state where the brake current command i * is fixed at the timing when the car speed V is detected.
  • the fact that the car speed V has been detected indicates that the brake torque T has become smaller than the torque resulting from the balance of the car and the balance weight.
  • the braking force of the brake is changed by continuously changing the brake current command according to the detected car speed V without increasing the change amount per unit time rapidly like a square wave.
  • the brake torque T is continuously controlled to control the car at a constant speed.
  • the brake torque is repeatedly applied as a square wave, the amount of change in the brake torque T per unit time is large, and the speed change per unit time of the car is also large as a result. And the car will vibrate.
  • the brake current is continuously controlled and the brake torque T is continuously changed. Therefore, the amount of change in the brake torque T is reduced, and rapid acceleration at the start of the movement of the car is prevented. In addition, it becomes possible to reduce the vibration of the car.
  • step S102 the brake current command creation processing unit 32 determines whether the car speed V is zero. If the car speed V is zero, the car is stopped by the brake, so the process proceeds to step S103 where the brake current i is increased to weaken the brake torque T, which is the braking force of the brake, and balance the car.
  • the brake current command i * is increased in order to balance the torque resulting from the unbalance of the weight and the braking force of the brake. Furthermore, by waiting for a predetermined time, the influence of the part due to the response delay of the brake is eliminated. After waiting for a predetermined time, the process returns to step S101. If the car speed V is not zero, the process proceeds to step S104.
  • this invention is not limited to the above-mentioned Example, Various modifications are included.
  • the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
  • a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment.
