Definitions

  • the present invention relates to an elevator control system for, when malfunction occurs in an electromagnetic brake to cause an elevator car to move while passengers get on and off the elevator car after the elevator car of an elevator is stopped at a certain floor, carrying out control so as to cause an electric motor to generate a torque used to prevent the movement of the elevator car to stop the movement of the elevator car of the elevator, thereby further enhancing safety for passengers.
  • a conventional elevator control system when malfunction occurs in an electromagnetic brake, restarts control for driving an electric motor, and operates an elevator car or counterweight at a safe speedup to a buffer to stop the elevator car or counterweight.
  • a tachometer generator for measuring a rotational speed of the electric motor is used, but a detector for measuring a rotational angle as well like an encoder is not used (refer to JP 61-86380 A (page 2 and page 3, and FIG. 1), for example).
  • the conventional elevator control system aims at merelymoving the elevator car including passengers to a safe position when malfunction occurs in the electromagnetic brake. Thus, it is not taken into consideration at all that the elevator car is prevented from being moved for the purpose of ensuring safety of passengers getting on and off the elevator car. In addition, for preventing the elevator car from being moved in such a situation, it becomes necessary to measure and control not only a rotational speed of the electric motor but also a rotational position of the electric motor. However, no consideration is taken with this respect.
  • the present invention has been made in order to solve the above-mentioned problems, and it is, therefore, an object of the present invention to obtain an elevator control system in which even when malfunction such as insufficiency in braking force occurs in an electromagnetic brake during activation of the electromagnetic brake, the braking force is increased by an electric motor to prevent passengers from being exposed to danger.
  • the present invention aims at ensuring a necessary standstill holding force while an elevator car is stopped to further enhance safety even when malfunction should occur in an electromagnetic brake by using control for a driving torque of an electric motor.
  • An elevator control system includes: a main rope for suspending an elevator car and a counterweight; a sheave wound with the main rope; an electric motor for rotating the sheave to move the elevator car; a controller for driving the electric motor; an electromagnetic brake for stopping the elevator car to hold the elevator car in a stationary state; and an encoder for detecting rotation of the electric motor.
  • a rotational angle of the electric motor is detected by the encoder. Then, the controller controls driving of the electric motor so as to generate a torque used to prevent the rotation of the electric motor to thereby bring the elevator car to a stationary state at a landing position of the hall.
  • FIGS. 1 and 2 are views each showing a schematic construction of the elevator control system according to Embodiment 1 of the present invention. Note that, in these figures, the same reference numerals designate the same or corresponding constituent elements.
  • FIG. 1 shows an embodiment in roping at a ratio of 1 : 1
  • FIG. 2 shows an embodiment in roping at a ratio of 2 : 1.
  • the load weighing device 10 is not necessarilymounted to the positions shown in the figures, and hence may be mounted to a position where a total weight of passengers and their loads within an elevator car 1 can be directly or indirectlymeasured.
  • FIG. 1 will hereinafter be described.
  • an encoder (rotation detector) 7 is directly connected to a shaft of the electric motor 5, it may be mounted to any position of a hoisting machine 8 as long as such a position allows the rotation of the electric motor 5 or the sheave 4 to be detected.
  • a detector for detecting movement of the elevator car 1 may also be mounted to the elevator car 1 in order to detect movement of the elevator car 1.
  • any other measuring instrument such as a resolver may also be adopted as long as it can detect a rotational angle of the electric motor 5 or the sheave 4.
  • a controller 9 drives the electric motor 5 to control an ascending/descending operation of the elevator car 1.
  • the controller 9 controls the driving of the electric motor 5 so as to generate a torque used to prevent rotation of the electric motor 5 to thereby stop the elevator car 1 at a landing position of a certain hall 12 in a stationary state.
  • FIG. 3 is a diagram showing a detailed configuration of the elevator control system according to Embodiment 1 of the present invention. Note that, a basic construction of FIG. 3 is the same as that of FIGS. 1 and 2 except that the mounting positions of the load weighing device 10 and the elevator car position sensors 11 are different from those shown in FIGS. 1 and 2.
  • the encoder 7 used as an example of a rotation detector generates a pulse signal (rotation signal) in accordance with the rotation of the electric motor 5. Consequently, by counting those pulses, it is possible to obtain a conversion value of a rotation amount of the electric motor 5 or the sheave 4, i.e., a movement amount of the elevator car 1, and it is also possible to obtain a moving speed from generation intervals of the pulses.
  • the load weighing device 10 is a device for measuring a payload such as passengers and the like within the elevator car 1.
  • the device which is provided between a car frame and the elevator car 1 suspended by the main rope 3. That is to say, there is adopted the construction that the load weight within the elevator car 1 is transmitted to the car frame through the load weighing device 10 (it should be noted that the function of the load weighing device 10 is the same as that of the load weighing device 10 provided between the main rope 3 and the elevator car 1 as shown in FIG. 1).
  • the elevator car position sensor 11 used as an example of a position detector is a sensor for detecting a position of the elevator car 1 in a hoistway of the elevator, and serves to detect a positional deviation amount or the like when the stop position of the elevator car 1 is deviated in an ascending or descending direction within the hoistway with a position of the elevator car 1 when properly stopped (this state is called landing) as a reference.
  • a door open sensor 15 is a sensor provided in the elevator car 1 for detecting that the door 13 of the elevator car 1 is opened.
  • An indicator 16 designates an indicator provided in the elevator car 1 in this example.
  • the indicator there are various kinds of notifying means for passengers including visually notifying information in the form of a pattern such as characters or a picture using a display device, notifying information in the form of an alarm sound using a buzzer, and telling information using a broadcasting device.

  • the operation control unit 901 carries out control for a normal operation of the elevator.
  • the operation control unit 901 issues a release command to release the electromagnetic brake 6 in accordance with an instruction for a operation, and issues a torque command for a torque to be generated by the electric motor 5 in accordance with a speed command arithmetically operated from a traveling speed pattern as a reference and a rotation signal from the encoder 7.
  • the operation control unit 901 issues a command for a restraint torque used to make the speed of the elevator zero and issues a command to operate the electromagnetic brake 6, and after stop of the elevator, outputs a stop signal.
  • the driving control unit 902 outputs a motor driving current in accordance with the torque command issued from the operation control unit 901 in order to cause the electric motor 5 to generate a specified torque.
  • the car position operation unit 903 serves to detect a movement amount (degree) from the reference value, e.g., a movement amount from a position where the elevator car 1 is to be stopped on the basis of the rotation signal from the encoder 7.
  • the car speed operation unit 904 detects a moving speed of the elevator car 1 on the basis of the rotation signal of the encoder 7.
  • the auxiliary torque quantity operation unit 905 arithmetically operates a quantity of torque to be generated in the form of an auxiliary torque in the electric motor 5 in accordance with a balance signal from the load weighing device 10, or a movement amount representing positional deviation of the elevator car 1 expressed by a signal from the car position operation unit 903, or a moving speed of the elevator car 1 expressed by a signal from the car speed operation unit 904 (refer to FIGS. 5 and 6) .
  • the auxiliary torque quantity operation unit 905 includes limitation means 906 for limiting the torque so as not to generate the torque larger than is needed, or for limiting a motor driving current, i.e., limiting the torque for the purpose of preventing burning of the electric motor 5 in order to prevent a main brake auxiliary torque from permitting a current to be continuously caused to flow through the electric motor 5 without releasing the electromagnetic brake 6.
  • the brake auxiliary torque control unit 907 while continuing to receive a door open signal which has been sent from the door open sensor 15 and which exhibits that the door 13 of the elevator car 1 is opened with an input of the stop signal from the operation control unit 901 exhibiting that the elevator has been stopped as a start, judges on the basis of an output from the car position operation unit 903 or the elevator car position sensor 11 that a position of the elevator car 1 is being deviated from the position where the elevator is to be stopped to issue a command to generate a brake auxiliary torque in the electric motor 5 for the brake auxiliary torque command unit 908.
  • the brake auxiliary torque control unit 907 even when the movement of the elevator car 1 is stopped, may continue to issue that command until the elevator car 1 starts to travel next time, or may continue to issue that command until the door 13 of the elevator car 1 is closed.
  • that command is a command for preventing the elevator car 1 from continuing to be deviated from the stop position at least while a stop mode is valid.
  • the brake auxiliary torque command unit 908 in response to the command to generate the brake auxiliary torque, outputs a motor driving current used to generate an auxiliary torque required for the driving control unit 902.
  • the battery 909 is a unit for storage of electricity which is provided for the purpose of allowing the main function to be maintained even in a power failure.
  • a secondary battery, a fuel cell or the like as well as a so-called lead storage battery may also be adopted as the battery 909.
  • the battery 909 is adapted to be connected to the driving control unit 902 in accordance with a battery connection signal from the brake auxiliary torque control unit 907 to supply a power supply.
  • the notification control unit 910 is a unit for operating the indicator 16 provided in the elevator car 1. A period of time when the main function of the brake auxiliary torque becomes valid corresponds to a period of time when the elevator car 1 is moved in spite of a door open state. Then, the notification control unit 910 carries out the control for the indicator 16 for informing passengers getting on the elevator car 1 of occurrence of a gap between a car floor and a hall floor, or informing passengers of that the main function of the brake auxiliary torque is intended to be utilized. In addition, since such a state may be caused in a case or the like where passengers over the designed capacity of the elevator car 1 get on the elevator car 1, the notification control unit 910 is also effective for information for urging some passengers to get off the elevator car 1.
  • FIG. 4 is a diagram showing a relationship between a load and an unbalanced load (compensation for 50% of the counterweight), and a braking force required for the electromagnetic brake.

  • the %load becomes a reference exhibiting the braking force of the electromagnetic brake 6.
  • Japanese Standard for a load up to 125%, an ability to safely decelerate the elevator car 1 to hold the elevator car 1 in a stationary state is required for the electromagnetic brake 6.
  • European Standard two sets of mechanical brakes are necessary as the electromagnetic brake 6.
  • the electromagnetic brake 6 is a unit which is very important for safety of the elevator.
  • a highly reliable method is adopted for the electromagnetic brake 6 in order to prevent any of failures or mal functions fromoccurring, and hence the periodic maintenance becomes essential to the electromagnetic brake 6.
  • a failure or malfunction occurs in the electromagnetic brake 6 resulting in insufficient braking force should be considered.
  • the present invention aims at providing the controller 9 for, when in a state in which after the elevator car 1 is stopped at a certain hall 12, the door 13 of the elevator car 1 is opened in order to permit passengers to get on and off the elevator car 1, and the standstill holding force of the electromagnetic brake 6 is insufficient due to malfunction of some sort in the electromagnetic brake 6 though the electromagnetic brake 6 is in operation to cause the elevator 1 to start a little movement, and thus the rotational angle of the electric motor 5 is detected by the encoder 7, carrying out control for driving of the electric motor 5 so as to generate a torque used to prevent the rotation of the electric motor 5 to thereby stop the elevator car 1 at a landing position of the hall 12 in a stationary state.
  • the present invention aims at providing the controller 9 for, when in a state in which after the elevator car 1 is stopped at a certain hall 12, the door 13 of the elevator car 1 is opened in order to permit passengers to get on and off the elevator car 1, the standstill holding force of the electromagnetic brake 6 is insufficient due to malfunction of some sort in the electromagnetic brake 6 though the electromagnetic brake 6 is in operation to permit the elevator 1 to start a little movement, and thus the rotational angle of the electric motor 5 is detected by the encoder 7, firstly carrying out the motor driving control for returning and moving the elevator car 1 to the position before the elevator car 1 starts the little movement, and next carrying out the motor driving control for causing the electric motor 5 to generate a torque used to prevent the movement of the elevator car 5 in order to maintain the stationary state of the elevator car 1.
  • the present invention aims at providing the controller 9 for, when in a state in which after the elevator car 1 is stopped at a certain hall 12, the door 13 of the elevator car 1 is opened in order to permit passengers to get on and off the elevator car 1, the standstill holding force of the electromagnetic brake 6 is insufficient due to occurrence of malfunction in the electromagnetic brake 6 to permit the elevator car 1 to start a little movement, and thus the rotational angle of the electric motor 5 is detected by the encoder 7, and the movement of the elevator car 1 is prevented in accordance with the control for a torque of the electric motor 5, and the door 13 of the elevator car 1 is then closed, stopping the operation of the elevator after releasing the torque control for the electric motor 5 to move the elevator car 1 to an uppermost portion of a hoistway when a total weight of the elevator car 1 is smaller than that of the counterweight 2 and to move the elevator car 1 to a lowermost portion of hoistway when the total weight of the elevator car 1 is larger than that of the counterweight 2.
  • the present invention includes the indicator 16 for, in a stage in which, when the elevator car 1 is stopped at a certain hall 12 and the door 13 of the elevator car 1 is opened, the elevator car 1 starts a little movement due to occurrence of malfunction in the electromagnetic brake 6, and the torque control for the electric motor 5 used to prevent the little movement of the elevator car 1 is activated to stop the elevator car 1, informing passengers within the elevator car 1 of that they are urged to go out into the hall 12 from the elevator car 1 using a display device, a broadcasting device, or a buzzer.
  • FIG. 5 is a diagram showing a relationship between the braking force generated by the electromagnetic brake and the payload of the elevator car.
  • a solid line I represents a relationship between the braking force generated by the electromagnetic brake 6 and the payload (%load) of the elevator car 1 while the elevator car 1 is stopped at the hall 12. Since when the payload of the elevator car 1 is smaller than 50% (indicated by a point M), the weight of the counterweight 2 is heavier than that of the payload of the elevator car 1, a force in an ascending direction acts on the elevator car 1. Thus, this force in the ascending direction is balanced with the braking force of the electromagnetic brake 6 in a descending direction to hold the elevator car 1 in a stationary state. When the elevator car 1 is empty, the braking force of the electromagnetic brake 6 in the descending direction becomes maximum.
  • Embodiment 1 An operation of Embodiment 1 will hereinafter be described by giving as an example a case where malfunction should occur in the electromagnetic brake 6 when the number of passengers within the elevator car 1 reaches nearly the passenger capacity.
  • the elevator car 1 starts to be moved in the descending direction.
  • the sheave 4 (or the electric motor 5) of the hoisting machine 8 is rotated by an angle determined on the basis of a movement amount of the elevator car 1, and a rotation amount of the sheave 4 (or the electric motor 5) is then detected by the encoder 7.
  • the controller 1 of Embodiment 1 judges that malfunction has occurred in the electromagnetic brake 6 to start the torque control for the electric motor 5 to generate the braking force (the torque generated by the electric motor 5) as indicated by a straight line (dotted line) II shown in FIG. 5, a polygonal line (broken line) III, or a polygonal line (dashed line) IV in accordance with the payload. If not only the rotation detected by the encoder 7, but also the output of the elevator car position sensor 11 are used at the same time for the judgment concerned with whether or not malfunction has occurred in the electromagnetic brake 6, then it is possible to enhance the accuracy for the judgment.
  • the elevator car 1 can be held in a stationary state. If the reduction in braking force due to malfunction in the electromagnetic brake 6 results in the braking force equal to or smaller than the braking force generated in accordance with the torque control for the electric motor of Embodiment 1, then the movement of the elevator car 1 can be prevented.
  • an output of the elevator car position sensor 11 for measuring an ascending or descending position of the elevator car 1 within the hoistway is used together with the output of the encoder 7 to enhance accuracy and redundancy.
  • FIG.6 is a diagram showing a relationship between the braking force generated by the electromagnetic brake and the payload of the elevator car.
  • a limitation may be given by the limitation means 906 of the controller 9 so that in order to prevent the electric motor 5 from being overloaded, the braking force generated as shown in FIG. 6 neither becomes equal to or larger than a value indicated by a point P nor equal to or smaller than a value indicated by a point Q.
  • This embodiment does not function when a power failure occurs in the power supply of the controller 9 occurs.
  • the controller 9 is provided with the battery 909 provided for coping with a power failure of the power supply.
  • measures to cope with a power failure are taken so that this embodiment functions even in when a power failure occurs.
  • the elevator control system when in a state in which after the elevator car is stopped at a certain hall, the door of the elevator car is opened to permit passengers to get on and off the elevator car, the standstill holding force of the electromagnetic brake is insufficient due to malfunction of some sort though the electromagnetic brake is in operation to cause the elevator car to start a little movement, and thus a rotational angle of the electric motor is detected by the encoder, the driving control for the electric motor is carried out by the controller so as to generate a torque used to prevent the rotation of the electric motor. Consequently, there is offered an effect that it is possible to obtain the elevator control system in which even when malfunction such as insufficiency in braking force occurs in the electromagnetic brake, the braking force is increased by the electric motor to prevent any of passengers from being exposed to danger.
