DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to elevator operation control, and more particularly to an elevator operation control device suitable for a passenger elevator carrying unspecified passengers.

[0002]

2. Description of the Related Art With the spread of residential elevators in recent years,
It has been proposed that the passengers in the car can perform a U-turn operation to return to the floor where they got in due to an urgent business, such as a thing left behind.

For example, in Japanese Unexamined Patent Publication No. 3-8676, by pushing the U-turn button in the car, the car is immediately stopped, and after the stop, the operation direction of the car is reversed and the operation direction of returning to the departure floor is stored. . Further, as described in JP-A-1-127576, there is also control for automatically returning to the boarding floor by effectively using the U-turn button (hereinafter abbreviated as U-turn).

[0004]

The subject of the above-mentioned conventional U-turn operation has been limited to elevators for exclusive operation such as VIP operation and elevators for private residences. For this reason, if the above-mentioned conventional U-turn operation is adopted for an elevator in which an unspecified number of passengers get on board, when the passenger is congested, one U-turn user can operate the elevator for many other elevator users. Because of the annoyance, I couldn't drive U-turn.

An object of the present invention is to eliminate this drawback and provide a U-turn device for a general elevator.

[0006]

[Means for Solving the Problems] As described above, in order to consider the overall operation status, a U-turn operation permission determination function, a U-turn operation function and a U-turn effective display function are provided, and group management The elevator is also provided with a function for reassigning hall calls that have already been assigned, so that the execution of U-turn control is instructed.

[0007]

The U-turn control informs that the U-turn operation is possible in the car only when the U-turn permission condition is satisfied. At that time, the process of permitting U-turn operation and performing U-turn operation is executed in response to the U-turn request of passengers in the car, and when the U-turn permission condition is not satisfied, U-turn is not permitted and U-turn operation is not performed Configured to perform the process. Also, in the group-controlled elevator, even if there is a hall call already assigned to the elevator, U-turn operation is permitted, and the assigned hall call is reassigned to another elevator.

By configuring the U-turn control means in this way, it is possible to prevent a U-turn operation that deteriorates the operating condition.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A U-turn control method according to the present invention will be described with reference to FIGS.

FIG. 1 (a) is an elevator car diagram. Install the operation control panel 2 in the elevator car 1
A turn button 3 is provided.

FIG. 2 is an explanatory diagram of the operation of the U-turn operation. At the time point t1, the elevator car 1 departs toward the F1 floor by the car call 6 registered by the passenger who gets in from the F7 floor, and at that time, step S1 in FIG.
At 5, the boarding floor 7 is memorized. At time t2, when the passenger in the car pushes the U-turn button when the U-turn operation is possible, the elevator car 1 is decelerated and the car call 6 is canceled. Time point t3 indicates that the elevator car 1 has stopped. Time point t4 indicates that the passenger is departing for the boarding floor 7.

FIG. 3 is a processing flowchart showing an embodiment of the first U-turn control in which the present invention is applied to a single elevator. The U-turn control program S5 is started after power-on or restart, and is started synchronously after completion of the initial processing. In step S10, it is determined whether or not the car departs from the calling floor. If the car departs, the floor in which the passenger boarded the car is stored in step S15. The state at this time is shown at time t1 in FIG.

Next, it is determined in step S20 whether or not the U-turn permission condition is satisfied. The U-turn permission conditions are, for example, when the elevator is not busy, the number of elevator car calls registered is one, there is no hall call assigned to the elevator, and the hall call floor stored in the boarding floor storage device last time is specified. For example, it is a floor or a specific floor.

When the U-turn permission condition is satisfied, the U-turn valid display etc. 4 shown in FIG.
Is turned on, the U-turn operation permission process is performed in steps S35 to S70, and when the U-turn permission condition is not satisfied, the U-turn valid display 4 is turned off in step S80 and the U-turn operation is not performed in steps S85 and S90. Perform permission processing.

In the U-turn operation permission process, it is determined in step U35 whether or not the U-turn button is pressed. If the U-turn button is pressed, the U-turn response lamp shown in FIG. 2 is turned on in step S40. The U-turn operation processing in steps S45 to S65 is performed as shown at time points t2 to t4 in FIG. After the U-turn operation process is completed, the U-turn response lamp is turned off in step S70. In the U-turn operation processing in steps S45 to S65, it is determined in step S45 whether or not the position of the preceding car is in the express zone at the time when the U-turn button is pressed, and if it is in the express zone, the car is set in step S50. Is stopped on the emergency floor, and if it is not in the express zone, the car is stopped on the nearest floor in step S55. Further, in step S57, even if a new call is generated during the U-turn operation processing, it is canceled. Whether there is a U-turn command and the car has stopped is step S6.
The determination is made at 0, the storage floor of the previous boarding floor storage device at step S15 is set as the return floor, and processing for automatically returning to this return floor is performed at step S65.

The U-turn operation disapproval process is step S5.
In step 2, it is determined whether or not the U-turn button has been pressed. If the U-turn button has been pressed, the passenger in the car is notified in step S90 that the U-turn operation cannot be performed.

FIG. 4 is a processing flowchart showing an embodiment of the second U-turn control in which the present invention is applied to a group control elevator. In FIG. 4, the item that there is no assigned hall call to the elevator is removed from the U-turn permission condition in order to make the most of the characteristics of the group-controlled elevator in step S.
In step S37 of the U-turn operation permission process from 30 to S70, the already assigned hall call is reassigned to another elevator.

[0018]

According to the present invention, the U
By controlling the turn, the U-turn operation that worsens the operation situation is prevented, and as a result, the U-turn operation can be adopted even in an elevator carrying an unspecified number of passengers.

Further, since the passenger in the car is informed that the U-turn permission condition is satisfied, the passenger in the car can easily know whether or not the U-turn operation is possible.
