Description

  The present invention relates to a method for improving a car position confirmation method in an elevator control device and performing it reliably and simply.

Conventionally, when a power failure occurs during operation of an elevator and is restored, gray code input is used to grasp the stop position (floor) after the power failure in order to prevent the current stop location from being lost. Such a recognition device (proximity SW, etc.) is arranged, and when the power failure is restored, the state of the recognition device is confirmed, the current position is grasped, and switching to the rescue operation and the automatic operation is performed.
In addition, the position detection device is composed of a plate to be detected arranged in the same line as the car ascending / descending direction in the hoistway, and a detector engaged in a non-contact manner with two different position ranges (zones). In order to provide an elevator position detecting device and an elevator position detecting device mounting adjustment device that can obtain a signal pattern and can easily adjust the mounting position of the detector and the plate to be detected, the elevator car is operated up and down. A to-be-detected plate having at least two or more to-be-detected portions arranged on the floor in the road so as to be in the same row as the car ascending / descending direction and having a different separation distance from the hoistway; And a detector having at least two or more detection switches that engage with the detection plate in a non-contact manner (see, for example, Patent Document 1).

  However, the above-described method has a problem that it is necessary to install a large number of recognition devices when the floor operated by the elevator is high, and the installation is troublesome.

  It is an object of the present invention to recognize an elevator floor in a method for recognizing the floor of an elevator without adding a device for recognizing even if the floor increases, and simplifying the installation work.

The elevator control method according to the present invention is an elevator operation control method comprising a means for calculating a car position by a pulse proportional to the amount of movement of the car and a floor recognition assisting device installed near the stop level. A detection level (1), a descending side car stop detection level (2), a rising side car stop level detection level, and a floor recognition level (11) of the same length as the descending side car stop level detection level. The floor recognition level (11) is arranged inside the ascending car stop detection level (1) and the ascending car stop level detection level so that there are not a plurality of the same arrangements on each floor. The rear elevator is operated, and the level difference between the upside car stop detection level (1) and the floor recognition level (11) and the downside car stop detection level (2) and the floor recognition at each floor. It is obtained so as to recognize the current floor on the basis of the level difference between the bell (11).
The present invention realizes accurate position detection by checking the installation status of the floor recognition device even when the current stop position of the elevator car cannot be determined.

  According to the present invention, it is possible to perform accurate floor recognition after reducing the number of elevator floor recognition input points, and there is an effect that installation work can be performed in the same manner as stop level detection.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a detection outline diagram according to an embodiment of the present invention, Table 1 is a table showing an arrangement example, and FIG. 2 is a flowchart.
First, an embodiment of the present invention will be described with reference to FIG.
The apparatus which detects the elevator car position is shown. In the ascending-side car stop level detection 1 and the descending-side stop level detection 2, the center of the overlapping portion of the detectors for stopping the car at the floor level is the car stop level. 11 is an input which is a means for recognizing the floor, and the same length as 1 and 2 is prepared. 11 is installed inside 1 and 2. At this time, the arrangement as shown in Table 1 is performed so as to have regularity, and so that a plurality of the same arrangements do not exist. In the case of an elevator with a high floor, a plurality of 11 are prepared and installed so that each arrangement is not the same.

After installation, the elevator is operated, and a and b of each floor are stored in a device that detects the car position.
Next, the operation when power is restored after a power failure will be described with reference to the flowchart of FIG. In FIG. 2, step 21 is for determining the stop position of the car. If it is determined that the car is stopped between the floors, the process proceeds to step 22. In step 23, it is determined whether or not it is a lift rescue operation. If YES, the process proceeds to step 24. If NO, the process proceeds to 25. The floor recognition pulse count in step 26 is started by detecting the level in step 24 or 25, and the floor recognition pulse count in step 28 is stopped by the floor recognition input in step 27. After the operation up to the stop level in steps 29 and 30 is performed, the floor recognition pulse count value in step 31 is compared with the stored floor recognition pulse to extract the corresponding floor and determine the floor recognition. If the stop position after a power failure is not between the floors, the operation to the outside of the stop level is once started in the floor recognition operation in step 32, and the car stop level is not detected in step 33, so that the rescue operation in step 22 is performed. Next, floor recognition is determined by the same process. As described above, the conventional floor recognition device is not necessary, and the floor recognition after a power failure can be accurately performed by preparing the minimum number of inputs. In the case of a fourth floor elevator, the number of input points for floor recognition can be reduced from three to one.
