Definitions

  • the present invention relates to a control device which performs the failure diagnosis of a door switch of an elevator.
  • An elevator is provided with a door switch which detects that a door (a car door and a hall door) is closed.
  • This door switch has a very high working frequency, and if a failure occurs the operation of the elevator must be suspended. For this reason, in elevators, it is necessary to try to detect failures early by conducting the failure diagnosis in normal times.
  • Patent Literature 1 proposes a technique which involves bringing an elevator from a normal operation into a diagnostic operation under prescribed conditions and conducting failure diagnoses of prescribed equipment, such as a position sensor.
  • Patent Literature 2 proposes a technique which involves detecting failure from the opening and closing torque, opening and closing time and the like of a door in a diagnostic operation for returning an elevator to a normal operation after the occurrence of an earthquake.
  • a control device comprises a car door provided in a car of the elevator; a door driving device which is provided in the car and drives the car door; a hall door provided in a hall of the elevator; a connecting device which causes the hall door to open and close in synchronization with the car door when the car has stopped at the hall; a car door switch which is provided in the car to detect that the car door is in a prescribed fully closed condition and goes into action when the car door has reached a prescribed position; door opening and closing control means which causes the car door to open beyond an action position of the car door switch after the car is stopped at the hall by the run control means and causes the car door to close without causing the car door to open to a width which is not less than a prescribed specified width through which an elevator user cannot pass.
  • a mode input judgment and processing section makes judgment on a test mode on the basis of a selected position of a mode selector switch. Further, when the selector switch is turned to test mode for making judgment about a door open/close zone on the basis of the combination of the on/off conditions of a plurality of door position detecting switches, a door open/close zone identified via the combination of the on/off state signals of each switch generated due to a current door position is shown on an LED display section via an output interface. Then, an elevator door is opened and closed manually, and the open/close zone thereof is compared with the displayed zone, thereby making judgment as to whether the door open/close zone is properly set.
  • the opening and closing of a door is performed without the registration of an elevator call (that is, without the pressing of a hall button and the like), which creates the possibility that the people of the building, condominium and the like who see the opening and closing actions of the door consider that the elevator has started moving automatically and mistake the movement for a failure.

  • FIG. 9 is a flowchart showing the actions of the control device of an elevator in a fourth embodiment according to the present invention.
  • a description will be given of the case where the timing of failure determination of the door switches 17 and 27 by the failure determination means 34 is determined on the basis of the positional information of the door.
  • a motor encoder (not shown) which outputs information according to the rotation of an output shaft of the door motor 11 is provided in the car 3 of the elevator. That is, the self-diagnosis apparatus 31 determines the above-described determination timing on the basis of the output information from this motor encoder.
  • the self-diagnosis apparatus 31 When a door opening action is started by the door opening and closing control means 33 after landing on a diagnostic floor (S404), the self-diagnosis apparatus 31 computes the position of the elevator door from the output information of the above-described motor encode and makes a determination as to whether or not the elevator door has moved to a prescribed specified position (S405). The self-diagnosis apparatus 31 causes the door opening action to stop at the instant the elevator door has moved to the above-described specified position, and a failure determination of the door switch 17 is carried out by the failure determination means 34 (S406).
  • the self-diagnosis apparatus 31 causes the door opening and closing control means 33 to start a door closing action, and the self-diagnosis apparatus 31 finishes the self-diagnosis action by causing the elevator door to be fully closed (S407).
  • the timing of failure diagnosis of the door switch 17 is determined on the basis of the positional information of the elevator door, whereby it is possible to clarify the above-described timing, enabling an accurate failure diagnosis of the door switch 17 to be conducted.
  • the self-diagnosis of the door switch 27 can be carried out by actions similar to those described above.
  • Figure 10 is a flowchart showing the actions of the control device of an elevator in a fifth embodiment according to the present invention.
  • a description will be given of the case where the timing of failure determination of the door switches 17 and 27 by the failure determination means 34 is determined on the basis of the time which elapses after the start of a door opening action of the car door.
  • the self-diagnosis apparatus 31 makes a determination as to whether or not the prescribed time has elapsed since the start of door opening of the car door (S505).
  • the self-diagnosis apparatus 31 causes the door opening action to stop at the instant the above-described prescribed time has elapsed since the start of the door opening, and carries out a failure determination of the door switch 17 by the failure determination means 34 (S506).
  • the self-diagnosis apparatus 31 causes the door opening and closing control means 33 to start a door closing action, and the self-diagnosis apparatus 31 finishes the self-diagnosis action by causing the elevator door to be fully closed (S507).
  • the timing of failure diagnosis of the door switch 17 is determined on the basis of the time which elapses after the start of a door opening action of the car door, whereby it is possible to clarify the above-described timing, enabling an accurate failure diagnosis of the door switch 17 to be conducted.
  • this embodiment has the advantage that the configuration can be simplified without the need of additional equipment, such as a motor encoder, in the car 3 of the elevator. Needless to say, the self-diagnosis of the door switch 27 can be carried out by actions similar to those described above.
  • Figure 11 is a flowchart showing the actions of the control device of an elevator in a sixth embodiment according to the present invention.
  • notification devices such as an indicator which indicates the position of the car 3, a hall lantern which forecasts the arrival of the car 3 and announcement equipment, are installed in the hall 1 of the elevator.
  • notification devices such as an indicator which indicates the position of the car 3, a hall lantern which forecasts the arrival of the car 3 and announcement equipment.
  • the self-diagnosis apparatus 31 performs control in such a manner as to temporarily suspend the notification function of the above-described notification devices.
  • the self-diagnosis apparatus 31 After guiding users out of the car in S603, the self-diagnosis apparatus 31 causes the notifying function control means 35 to put out the light of the notification devices and to silence the notification devices, thereby causing the functions thereof to be suspended (S603). After the suspension of the functions of the notification devices, the self-diagnosis apparatus 31 causes the car 3 to land on a diagnostic floor, starts a door opening action, and causes the elevator door to be opened to a prescribed specified width (S604 to S606). Incidentally, the determination in S606 may be made in the same manner as S305 of Figure 8 , 405 of Figure 9 , or S505 of Figure 10 .
  • the self-diagnosis apparatus 31 causes the door opening action to be stopped at the moment the elevator door has opened to the above-described specified width, and carries out a failure determination of the door switch 17 by the failure determination means 34 (S607).
  • the self-diagnosis apparatus 31 causes the door opening and closing control means 33 to start a door closing action and to fully close the elevator door, and thereafter the self-diagnosis apparatus 31 finishes the self-diagnosis action (S608).
  • the self-diagnosis apparatus 31 causes the notifying function control means 35 to recover the notifying function of the notification devices (S609).
  • the various kinds of notification devices such as the indicator, hall lantern and announcement equipment, function normally to suit the operation of the elevator.
  • the sixth embodiment of the present invention there is no possibility that during a self-diagnosis of the door switch 17, various kinds of guidance might be provided by the notification devices installed in the hall 1. For this reason, the users present in the hall 1 are not conscious of the elevator actions during a self-diagnosis, and it is also possible to positively prevent the users from mistaking the elevator actions for a failure of the elevator. Incidentally, it is needless to say that a self-diagnosis of the door switch 27 can be carried out by actions similar to those described above.
  • the control device of an elevator according to the present invention can be applied to an elevator in which a door switch which detects the fully closed condition of an elevator door is installed in a hall or a car.
