Embodiment 1 FIG.
1 is a system configuration diagram illustrating an elevator remote control device according to Embodiment 1 of the present invention. In FIG. 1, a control room 3 is provided in an upper part of a hoistway 2 formed in a building having a landing 1. The control chamber 3 controls the driving device 7 by sending a driving signal to the hoisting device 6 for driving the hoisting device 6, the hoisting device 6 for raising and lowering the car 5 supported by the rope 4, and the driving device 7. A control device 8 is installed. The control device 8 is configured to control the movement of the car 5 and to grasp the moving direction of the car 5 and the distance moved. The drive device 7 may have a configuration in which the control device 8 has the function.

  In the car 5, an operation terminal 9 that generates and transmits a signal for operating the car 5, a signal reception device 10 that receives a signal from the operation terminal 9, and a signal output from the signal reception device 10 are transmitted. A signal analysis device 11 for analysis and a display device 12 for outputting movement distance information of the car 4 by an operation described later are provided. The operation terminal 9, the signal receiving device 10, the signal analysis device 11, and the display device 12 constitute an elevator remote control device. However, the operation terminal 9 is not necessarily provided in the car 5, and is carried. A free portable operation terminal may be used, and the signal receiving device 10 may have a configuration in which the signal analyzing device 11 has the function.

  The elevator remote control device according to the first embodiment is configured as described above, and the operation thereof will be described next. In FIG. 1, an operation signal a1 transmitted from the operation terminal 9 is received by the signal reception device 10 and transmitted to the signal analysis device 11 as reception information a2. The signal analysis device 11 analyzes the content of the received reception information a2 and transmits it to the control device 8 as control information a3.

  Based on the received control information a3, the control device 8 transmits the moving direction of the car 5 and the distance to be moved to the display device 12 as display information a4, and also transmits to the drive device 7 as car control information a5. The display device 12 receives the display information a4 from the control device 8, and outputs the moving direction and moving distance of the car 5. Further, the driving device 7 sends the moving amount of the car 5 to the hoisting device 6 as the car moving information a6 based on the car control information a5, and the hoisting device 6 winds up the rope 4 based on the received car moving information a6. Take control.

  FIG. 2 is a diagram for explaining a specific example of the data a1 to a6 shown in FIG. In FIG. 2, an operation signal a <b> 1 is a radio signal transmitted from the operation terminal 9 by the user to arbitrarily move the car 5, and is a radio signal such as infrared rays. The reception information a2 is information received by the signal reception device 10 detecting the operation signal a1. The control information a3 is information for controlling the movement of the car 5, in which the contents of the received information a2 are analyzed by the signal analyzer 11 and the contents of the received information a2 are used to determine how the car 5 is moved. For example, it is information such as moving in the upward direction, moving in the downward direction, and stopping.

  The display information a4 is information indicating the movement distance of the car 5 in numerical values, which is transmitted to the display device 12 when the control device 8 analyzes the contents of the control information a3 and moves the car 5. For example, information such as −10 cm, +7 mm, and ± 0 mm. The car control information a5 is transmitted to the driving device 7 when the control device 8 analyzes the contents of the control information a3 and moves the car 5, and is information that activates the driving device 7 to move the car 5. For example, it is information such as lowering the rope 4 by 10 cm, winding the rope 4 by 7 cm, and stopping the winding. Further, the car movement information a6 is information that the driving device 7 activates the hoisting device 6 to move the car 5 by an arbitrary distance based on the contents of the car control information a5. It is information such as winding up and stopping.

  FIG. 3 is a diagram illustrating, in time series, how each device handles each piece of information shown in FIG. In FIG. 3, when the car 5 is desired to be moved arbitrarily, the operator inputs a signal in the moving direction using the operation terminal 9 (operation signal input b0).

  The operation terminal 9 creates information (operation signal a1) for moving the car 5 in an arbitrary direction based on the input signal, and transmits the information to the signal receiving device 10 (car operation information transmission b1).

  When receiving the operation signal a1, the signal reception device 10 creates reception information a2 and transmits it to the signal analysis device 11 (reception information transmission b2).

  The signal analysis device 11 analyzes the content of the reception information a2, extracts information for moving the car 5 in an arbitrary direction, and transmits the control information a3 to the control device 8 (analysis result information transmission b3).

  The control device 8 calculates the distance by which the car 5 is moved from the content of the control information a3, transmits the calculated result to the display device 12 as display information a4 (car movement information transmission b4), and the display device 12 receives the received information. Information to be updated is created from the display information a4 and the currently displayed content, and the display is updated (car position display b5).

  At the same time that the control device 8 performs the car movement information transmission b4, the control device 8 transmits to the drive device 7 information on the movement distance determined from the content of the control information a3 as car control information a5 (drive information transmission b6).

  The drive device 7 calculates the amount by which the rope 4 is wound up from the content of the received car control information a5, and transmits the calculated result to the hoisting apparatus 6 as the car movement information a6 (winding information transmission b7).

  The hoisting device 6 performs the hoisting process on the rope 4 based on the content of the received car movement information a6 and moves the car 5 (winding operation b8).

  As described above, according to the elevator remote control device of the first embodiment, the elevator car stop position can be remotely operated to an arbitrary position, and the position of the moved car 5 can be displayed numerically. For example, the range of maintenance can be expanded, for example, by accurately grasping the start position of the door zone.

  In addition, since the position (movement distance) of the car 5 can be confirmed, conventionally, when performing maintenance work on the car 5, one person gets into the car 5 and manually moves the car 5, and the other person It is possible to reduce the trouble of riding on the work.
