Abstract

PROBLEM TO BE SOLVED: To provide a control device for an elevator preventing as far as possible giving a feeling of physical disorder to a passenger, in the case that the elevator, detecting its abnormality, is once stopped and then its operation is restarted. SOLUTION: When abnormality of an elevator is detected by an abnormality detector 1a, the elevator is stopped by an emergency stopper device 1b, a direction of running just before stopping is stored in a memory unit 1d for a direction of running in the preceding time. When no abnormality is detected of the elevator in the abnormality detector 1a, a rescue operating device 1c, with an existing register call made as left, makes the elevator travel to the adjacent stop floor in a direction of running in the preceding time stored in the memory unit 1d for a direction of running in the preceding time, ordinary operation is restarted. In this way, operation can be restarted by preventing as far as possible giving a feeling of physical disorder to a passenger.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator control device that performs a rescue operation when an abnormality of an elevator device is detected.

[0002]

2. Description of the Related Art An elevator control device constantly monitors signals from sensors for detecting the position of a car, the open / closed state of a door, and the like, current and voltage of motor control, and the temperature of control equipment. Has a protection function of stopping the elevator when it is detected. At this time, if the elevator stops between floors, the elevator has a function of running the elevator to the nearest stop floor to rescue passengers.

[0003] Furthermore, when it is determined that these abnormalities are temporary and it is acceptable to restart the operation of the elevator, the system has a function of restarting the operation of the elevator.

[0004]

However, when an elevator abnormality is detected and stopped, the already registered call is canceled, and even if the operation is resumed immediately, the passenger must register the call again. Elevator not available. Particularly for passengers waiting for the elevator at the landing, there is a possibility that the use of the elevator will be abandoned when the call is canceled.

Accordingly, an object of the present invention is to provide a method for detecting an abnormality in an elevator, temporarily stopping the elevator, and then restarting the operation.
An object of the present invention is to provide an elevator control device that does not give a passenger uncomfortable feeling as much as possible.

[0006]

In order to solve such a problem, an elevator control apparatus according to the present invention according to a first aspect of the present invention includes an abnormality detecting means for detecting an abnormality of an elevator, and an abnormality detecting means for detecting an abnormality of the elevator. Emergency stop means for stopping the elevator when the elevator is stopped, the previous traveling direction storage means for storing the traveling direction immediately before stopping by the emergency stop means, and the abnormality detection means for stopping the elevator after the emergency stop means stops the operation. And rescue driving means for resuming operation by running to the nearest stop floor in the previous running direction stored by the previous running direction storage means while retaining the registered call when the detection is stopped. It is characterized by.

According to the first aspect of the present invention, when the emergency stop device stops the elevator by detecting the abnormality by the abnormality detecting means, the rescue driving means is stored in accordance with the traveling direction stored in the previous traveling direction storage means.

In addition, the normal operation abnormality detection number counting device 3a is provided with the abnormality detection device 1 for a certain period of time.
If no abnormality detection signal is received from a, the number of times of abnormality detection is returned to zero.

At this time, if the number of abnormality detections received from the abnormality detection number counting device 3a during normal operation exceeds a certain number of times (step S8), the operation stop device 3b outputs an operation stop command to the rescue operation device 1c and Then, the registered call is canceled (step S9).

Next, when the abnormality detecting device 1a stops detecting the abnormality of the elevator (step S4), the abnormality detecting signal output to the emergency stop device 1b and the rescue operation device 1c is deleted. When the abnormality detection signal from the abnormality detection device 1a is deleted, the rescue driving device 1c receives the previous traveling direction from the previous traveling direction storage device 1d, and causes the elevator to travel to the nearest stop floor in the previous traveling direction (step S5,
In step S6), if the operation stop command is output from the operation stop device 3b (step S10), the operation is not returned to the normal operation (step S11).

In this way, if an abnormality is detected more than a certain number of times within a certain time, the operation is stopped after the rescue operation. That is, if an abnormality is detected more than a certain number of times within a certain time,
Although the driving to the nearest stop floor in the previous traveling direction is performed by the rescue operation, it is determined that it is not preferable to perform the further operation, and the operation is stopped after the rescue operation.
