2. Description of the Related Art In an elevator that has been generally used in the past, if a door is broken, the door cannot be opened, and the car cannot move from that floor, which makes the car inoperable.
Therefore, conventionally, as an elevator operation device that solves this problem, when the door of the floor does not open even if a certain time (for example, 8 seconds) elapses when the elevator stops in response to a call, One that gives up the door open and moves to another floor (Japanese Patent Laid-Open No. 53-107050) and, at the same time, automatically registers the hall call on the floor that cannot be opened again to prevent annoyance to passengers at the hall. There is a proposal (Japanese Patent Laid-Open No. 60-87174).

[0003]

However, in the elevator driving apparatus having the above-described structure, the car must always be moved to the floor where doors cannot be opened to perform the door opening operation, which deteriorates the operation efficiency. In addition, although it is a remedy to some extent for passengers at the hall, if the car stops responding when there is a call on another floor, it will not be able to get off and you will drive to those floors, It was an unfriendly operation for the person riding on.

Therefore, according to the present invention, the elevator which can store (learn) the floor that cannot be opened in advance, prevent the operation efficiency from being lowered, and can perform an appropriate driving operation with respect to a hall call or a car call. It is an object to provide a driving device of

[0005]

According to a first aspect of the present invention, there is provided an elevator driving apparatus, including a door opening failure detecting means for detecting a door opening failure when a call response of a group-controlled elevator car is stopped, and a door opening failure detecting means. When the door open defective floor storage means that stores the floor where a defect is detected for each unit and the hall call button on the defective door opening is pressed, the vehicle that is not stored as the defective door open is given priority It is provided with a car selection means.

An elevator driving apparatus according to a second aspect of the present invention is provided with a boarding / alighting judging means for judging passengers getting on and off in the car, and the door opening failure detecting means detects a door opening failure, and the boarding / alighting judging means. When it is determined that there is no passenger getting on and off, the vehicle is provided with a door-opening failure determining means that determines that the door is not truly open.

In the elevator driving apparatus according to the third aspect of the present invention, when the door opening defective floor storage means and the passenger registering the car call of the defective door opening floor, the nearest stoppable nearest the defective door opening floor. A car call registration changing means for automatically registering a car call for a floor and canceling a car call for a floor with a poorly-opened door, and a notifying means for notifying passengers to that effect.

[0008]

According to the first aspect of the invention, when the hall call button on the floor where the door is not open is pressed, the elevator car that can normally open the door is preferentially dispatched by the dispatch car selecting means. The unpleasantness of not being able to get in due to poor opening can be eliminated, and as a result, driving efficiency does not decrease.

According to the second aspect of the present invention, since the boarding / alighting judgment means is used for judging the door-opening failure floor and the presence / absence of passengers getting on / off is also a condition, it is possible to limit to a true door-opening failure incapable of getting on / off. , Minimize service degradation on that floor.

According to the third aspect of the present invention, the car call registration change means and the notification means prompt the passengers who want to go to the floor with poor door opening to get off at the nearest floor where the car can be stopped. As a result, the door will not be able to get off due to poor door opening, and you will not travel to other floors far away, which will reduce annoyance to users.

When the hall call button 5 is pressed at the hall on the Nth floor, this signal is supplied to the group management control device 17 by the hall call button signal input means 6, this hall call is registered, and the vehicle dispatch in the group management control device 17 is performed. The car selecting unit 7 selects the M-th car, and it is determined in step S30 whether or not the door-opening command is output to the M-th car. If the door-opening command is not output, the process ends.

If the door opening command is output, step S
At 30A, the car load value from the car device 2 at that time is stored (CAR KG ← car load value) (car load value storage means), and the process proceeds to step S31. In step S31, it is determined whether or not the door is fully opened within a predetermined time based on the signal from the door opening failure detection means 3. When the door is fully opened within the predetermined time, the process proceeds to step S35, and various flags and memories are cleared (DOOR ERR (M, N) ← 00, DOOR
NG (M, N) ← 00) is performed and this processing is finished.

If the door is not fully opened within the predetermined time in step S31, the car load value at that time is compared with the car load value stored in step S30A in step S31A, and a certain specified value (for example, ± 25 kg) or more If there is a change in, it is determined that the passenger has boarded / unloaded (boarding / alighting judgment means), and this processing ends. If there is no change in the car load value over a specified value (for example, ± 25 Kg), it is determined that it is a true door-open failure in which entry / exit is impossible, and step S32 similar to FIG.
~ 34 processing is performed.

It is based on the consideration of car calls. In step S40, it is determined whether or not the car call on the Nth floor by pressing the destination button in the car has been registered (car call registration determining means). If not registered, this process is terminated and registered. If so, the process proceeds to step S41, and it is determined based on a signal from the defective door-opening floor storage means 4 whether or not the N-th floor has a defective door-opening floor. Then, if there is no memory of the door-open failure floor, this process ends, and if there is memory of the door-open failure floor, step S4.
Move to 2.

In step S42, the nearest floor (excluding the service separation floor, the secret floor, etc.) that is the closest to the N floor and is the closest to the floor (floor that requires a little effort even when using stairs) is excluded. Calculate (I ← calculation floor). Further, step S4
In No. 3, passengers cannot get off on the N floor, so to get to passengers on the N floor, get off at the nearest floor closest to the N floor and use another elevator or stairs. Notify by voice announcement or display (notification means).

Next, the process proceeds to step S44, the car call on the I floor closest to the N floor is registered (nearest floor car call registration means), and the process proceeds to step S45. In step S45,
The first registered car call on the Nth floor is canceled (car call canceling means), and this process ends. In addition, in this embodiment, the processes of step S44 and step S45 are collectively referred to as car call registration changing means.
