Abstract

To operate an elevator so as to reduce waiting time for a user at a landing while preventing a user in a car from getting off in a direction different from a boarding direction.SOLUTION: The method is for controlling an operation of a two-way elevator having a car 5 which is installed at a boundary of two areas in a building and in which doors are installed in directions corresponding to the two areas and operated so as to prevent a user boarding the car 5 from the area of one direction from getting off at the area of the other direction. When switching an operation from a reciprocating operation in the area of one direction to a reciprocating operation in the area of the other direction, the door is closed to move the car to a first floor if a user in the car has been detected. After the door of a direction before operation switching is opened and closed at the first floor, a pre-switching process for opening the door of the direction before the operation switching at a lowest floor is repeated until no user is detected in the car. Then, an operation is switched from the area of one direction to the area of the other direction.SELECTED DRAWING: Figure 1

Description

  Embodiments described herein relate generally to a two-way elevator operation control method and control device.

  Conventionally, a two-way elevator with doors installed in two directions of the car is installed at the boundary between the two areas in the building, and a user who has entered the car from the one direction area gets out of the area in the other direction. You may drive to avoid. For example, a two-way elevator is installed at the boundary between the inside and outside the ticket gate inside the station, and the elevator is operated by the user at the inside of the ticket gate while responding to the elevator call generated by the user operation outside the ticket gate. Even if a call occurs, it will be in a response waiting state. Then, after the responses to all the calls generated by the operation of the user outside the ticket gate are completed, the calls generated by the operation of the user inside the ticket gate are answered. By driving the two-way elevator in this way, it is possible to avoid a user who has entered the car from the area outside the ticket gate from getting out of the area inside the ticket gate.

  However, when a two-way elevator that operates as described above is installed in a building with a larger number of floors than the station premises, calls are continuously generated in any one direction, so that calls in other directions take a long time. You may not be able to respond.

  For example, if you install a two-way elevator in a building that has a residential area and an office area, and you drive to avoid getting in the office area from a user who has entered the car from the residential area, When the number of users on the residential area increases during school hours and calls are made continuously in that direction, there is a problem that users on the office side must wait for a long time at the landing.

  The present invention has been made in view of the above circumstances, and it is possible to reduce the waiting time of the user at the landing as much as possible while preventing the user in the car from getting off in a direction different from the direction of the boarding. It is an object of the present invention to provide an operation control method and a control device for a two-way elevator that is operated in the same manner.

  An aspect for achieving the above object includes a car installed at a boundary between two areas in a building, and a door installed in a direction corresponding to each of the two areas. An operation control method for a two-way elevator that operates so as to avoid that a user who has entered a car gets off in an area in another direction, and is a reciprocating operation in an area in another direction from a reciprocating operation in one area. When a user is detected in the car when switching to a car, the door is closed and the car is driven to the first floor, and the door in the direction before the operation is switched on the first floor. After opening and closing the door, move to the lowest floor, repeat the pre-switching process to open the door in the direction before the operation switch on the lowest floor until no users are detected in the car, It is possible to switch operation from one direction area to another direction area. The features.

<Processing Procedure of First Embodiment>
When the user operates the bottom floor landing button 1xb in one area and the bottom floor landing button 1xb in one area is registered, the bottom floor landing button signal S1xb in one area is sent to the signal input device 72. When the data of the lowest floor landing button signal S1xb of one area inputted to bit <0> changes from 0 to 1, the arithmetic processing unit 71 takes the bit <0> of the signal output device 73 to the lowest floor. A signal for driving the car 5 is output to the hoisting machine 3 (step ST1).

  When the car 5 arrives at the lowest floor of one area, the user gets into the car 5, registers the car call button xkb on one side, and registers the car call button xkb on one side. The car call button signal Sxkb is input to the bit <6> of the signal input device 72. When the data of the input car call button signal Sxkb on one side is changed from 0 to 1, the signal for causing the car 5 to travel to the destination floor from the bit <6> of the signal output device 73 by the arithmetic processing device 71 is sent to the hoisting machine 3 (Step ST2).

  After arrival at the destination floor, the bit <8> of the signal output device 73 outputs a door opening / closing signal Sxo on one side to the car inner door xkd on one side, and opens and closes only the car inner door xkd on one side of the destination floor. The passenger is boarded and exited (step ST3).

  When the car call button xkb on one side of the car 5 and the call on the upper side disappear, it responds to the hall and car call on the lower side of one area X. For example, when the intermediate floor landing button 2xb of one area is registered, the intermediate floor landing button signal S2xb of one area is input to the bit <1> of the signal input device 72, and the intermediate floor of one input area is input. When the landing button signal S2xb changes from 0 to 1, the arithmetic processing unit 71 outputs a signal for running the car 5 from the bit <1> of the signal output unit 73 to the intermediate floor to the hoisting machine 3 (step ST4).

  When responding to the call on the lower side, only the door on the one area X side is opened and closed on the floor where the floor is landed, and the door on the other area Y side is not opened and closed (step ST5).

  Here, when the registration of the car call button xkb on one side in the downward direction is lost, it is determined whether or not the car 5 is on the lowest floor (step ST6).

  When the car 5 is not the lowest floor (NO in step ST6), the car 5 is moved to the lowest floor (step ST7).

After the car 5 moves to the lowest floor, the door opening / closing signal Sxo on one side is output to the car inner door xkd on one side to open / close the door on one side (step ST8).

  If the car 5 is on the lowest floor (YES in step ST6), if the data of the load detection device 8 in the car is 1, it is determined that the user is in the car (YES in step ST9). Drive to the floor above the first floor. After landing on the first floor, the door opening / closing signal Sxo on one side is output to the car door xkd on one side to open and close the door on one side and perform the reciprocating operation to land on the lowest floor (step ST10). ).

  Thereafter, when the data of the load detection device 8 is 0 (step ST9), the car door xkd on one side is closed and the door opening / closing signal 3z on the other side is sent from the bit <9> of the signal output device 73 to the other side. After outputting to the car inner door ykd and opening the car inner door ykd on the other side, the operation is switched to the operation on the other side (step ST11).

  When the first floor reciprocating operation is repeated for a certain time, a notification is issued to a management device installed in a manager's room or the like (steps ST12 and ST13).

  The above is the processing of one region, but the processing of the other region can be applied by replacing one side of the steps in the flowchart of FIG. 3 with the other side, and thus illustration and description thereof are omitted.

  Thus, according to the first embodiment, after the end of the reciprocating operation in one region X, the load detection device 8 in the car determines whether or not there is a user in the car and the user is not on the board. If it is determined that the operation is switched to the other area Y, and it is determined that the user is on board, the first floor reciprocating operation is performed in one area X, so that the operation is different from the normal elevator operation. (Unnatural driving) Since the user feels uncomfortable, the user can be prompted to get off.
