Abstract

PROBLEM TO BE SOLVED: To provide an elevator control device which cancels useless operation of an elevator.SOLUTION: The elevator control device is connected to an elevator cage, destination floor buttons which are set in the cage and transmit cage call, a cage door, and a load detection device for detecting a load on the cage. The elevator control device confirms the closed state of the door after stop of the cage on a prescribed floor for a prescribed period of time, and checks the presence or absence of cage call. If there is the cage call, the cage call is cancelled when determining that there is no passenger in the cage on the basis of the load from the load detection device.

Description

  The present invention relates to an elevator control device and a control method, and more particularly to a control device and a control method for preventing mischief of a car call button.

  In Patent Document 1, the maximum number of registered car calls according to the number of cars corresponding to the car load weight is set, and by not registering the car calls exceeding the maximum number of registered car calls, the car call button is prevented from being tampered with, and the elevator is wasted A technique for preventing the movement of the camera is disclosed.

  Patent Document 2 discloses a technique in which when the number of passengers exceeds the number of car calls, it is determined that the call is a mischievous call, all car call registrations are canceled, and the car call registration is performed again.

  Calling a car is pressing the destination floor button in the elevator car. If an elevator passenger gets on the first floor, for example, presses the destination floor button (for example, the 10th floor), and for some reason presses the button on the previous floor (for example, the third floor) and gets off the elevator, Even if you are not riding, there is a waste of driving to the first destination floor (10th floor).

  As another example, when an elevator stops on an intermediate floor, for some reason, all passengers may get off the elevator without going to the original destination floor. Even if there are passengers waiting to go in the opposite direction to the original destination floor on the intermediate floor, useless driving in the direction of the original destination floor is performed.

  If the destination floor button is pushed by mischief when the passenger gets off the elevator, the elevator is wasted to the floor where the destination floor button is pressed.

  In such a case, it is necessary to cancel the useless operation of the elevator.

  The disclosed elevator control device is connected to an elevator car, a destination floor button for transmitting a car call provided in the car, a car door, and a load detection device for detecting the car load. The elevator control device stops on a predetermined floor of the car for a predetermined time, confirms the closed state of the door, checks whether there is a car call, and if there is a car call, there is no passenger based on the load from the load detection device Cancel the car call.

  According to the present invention, useless operation of an elevator can be stopped.

It is a schematic diagram of an elevator system. It is a process flowchart of a control apparatus.

  FIG. 1 shows a schematic diagram of the elevator system. The elevator car 1 is connected to a CW (counterweight) 5 by a rope, and is lifted / lowered by the operation of the hoisting machine 4. A drive control device 3 controlled by an elevator control device (hereinafter referred to as a control device) 2 operates the hoisting device 4. In response to a floor call in which a button (not shown) installed on a floor on which passengers who use the elevator board the board is pressed, the control device 2 controls the drive control device 3 and the hoisting machine 4 to control the car 1. The car 1 is raised or lowered to stop the car 1 on the floor where the floor call was made.

  After the arrival of the car 1 and the opening of the door 7, the passenger gets into the car 1 and presses the destination floor button 6, whereby a car call is input to the control device 2 via the signal line 9. After the predetermined door opening time has elapsed or the completion of passenger boarding / exiting has been confirmed, the control device 2 applies a predetermined load (rated load) via the signal line 11 from the load detection device 8 attached to the car 1. If it does not exceed, the door 7 is instructed to close via the signal line 10. If the load exceeds the predetermined load, the control device 2 issues an alarm by a buzzer or the like, waits for the load to become lower than the predetermined load, and if the load becomes lower than the predetermined load, the signal line 10 The door 7 is instructed to close. After confirming the closed state of the door 7, the control device 2 controls the drive control device 3 and the hoisting machine 4 so as to drive the car 1 toward the destination floor indicated by the destination floor button 6 pushed by the passenger.

  The above is the normal control of the elevator, but as described above, there is a state in which the passenger is not on the car 1 even though the destination floor button 6 is pressed. Processing of the control device 2 for dealing with such a state will be described.

  FIG. 2 shows a process flowchart of the control device 2. The process of FIG. 2 is executed following the confirmation of the above-described passage of the predetermined door opening time or the completion of passenger boarding / exiting. Input the load via the signal line 11 from the load detection device 8 (S20), check whether it exceeds the predetermined load (rated load) (S21), and if the load exceeds the predetermined load, The control device 2 issues an alarm with a buzzer or the like, and returns to S20. If the load does not exceed the predetermined load, the door 7 is instructed to close via the signal line 10 (S22).

  Check that the door is closed (S23), and check for a car call (S24). If there is no car call, go to S28. If there is a car call (if the destination floor button 6 is pressed), a load is input via the signal line 11 from the load detection device 8 (S25), and the presence or absence of the load is checked (S26). This check for the presence or absence of a load means a check for the presence or absence of a passenger. If there is a load, that is, there are passengers, the car 1 is normally operated toward the destination floor indicated by the destination floor button 6 (S30). If there is no load, that is, there are no passengers, the car call is canceled (not used for operation control to the destination floor), the display of the pressed destination floor button 6 is turned off (S27), and the process proceeds to S28.

  Since there is no car call, the presence / absence of the floor call is checked without executing the control for moving the car 1 and with the door 7 closed until there is a floor call (S28). If there is a floor call, the vehicle is normally driven toward the call floor that issued the floor call (S29).

  As described above, before the door 7 is closed and the normal operation to the destination floor is started, if the load is detected and the destination floor button 6 is pressed even though there is no load, the destination floor button 6 By canceling the car call due to the being pushed, it is possible to avoid useless driving of the elevator to the destination floor without passenger movement.

  In addition, in order to prevent erroneous control due to load detection error (withdrawal of driving to the destination floor even if there are passengers), the purpose of “stop driving” is broadcasted for guidance for a predetermined time. After confirming that there are no calls, it is recommended to move to the process of checking whether there is a floor call. If there is a car call while it is confirmed that there is no car call, normal operation to the destination floor corresponding to the car call is executed.

  In this embodiment, an elevator of a type in which a rope connecting a car and a counterweight is wound up by a hoisting machine is taken as an example. However, even with other corresponding elevators such as an elevator operated by hydraulic pressure, FIG. The processing of the control device 2 described is applicable.

  As explained above, useless operation of the elevator can be stopped.

  1: elevator car, 2: elevator control device, 3: drive control device, 4: hoisting machine, 5: counterweight, 6: destination floor button 6, 7: door, 8: load detection device, 9-11: Signal line.
