Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art In a hydraulic elevator, the structure of lifting and lowering an elevator riding basket by expanding and contracting a hydraulic jack makes the basket lighter when many passengers get out of the basket. It will shift upward. On the other hand, when a large number of passengers get into the empty basket, the basket becomes heavy and the hydraulic jack contracts, causing the basket to shift below the landing level. In order to solve this problem, there is a case where an elevator is equipped with a door opening releveling device as a device for correcting a floor shift caused by getting in and out of passengers while the flooring door is open. This door-opening releveling device lowers the floor to the landing level when the elevator causes an upward floor displacement, and conversely performs the ascending operation to the floor level when a floor displacement occurs downward. In particular, it is very useful for wheelchair users to facilitate getting on and off the wheelchair. Moreover, even in elevators other than hydraulic elevators, especially in high-floor elevators, door opening and closing levels are performed because the same floor displacement occurs due to rope expansion and contraction.

[0003]

This is an effective door opening releveling device for wheelchair users, but in the case of general users only, the elevator is intended for the door opening releveling operation even after the passengers have finished getting on and off. It is not possible to start traveling toward the floor and wait for the end of the door-open releveling operation. This not only increases passenger irritability but also lowers transportation capacity. However, since this door opening releveling device is very effective for wheelchair users, door opening releveling is often performed even at the expense of reduced driving efficiency. An object of the present invention is to provide a door opening releveling device for an elevator that does not cause a reduction in operating efficiency.

[0004]

FIG. 1 is a block diagram showing the configuration of the present invention. In the figure, 1 is a door opening detection device that detects that the elevator has opened the door and is stopped, 2 is a floor displacement detection device that detects that the elevator has caused a floor displacement from the landing level due to passenger getting on and off, 3 is a handicapped person call detection device for detecting that a person with a disability call registration has been generated by a person with a disability call button, 4 is a door open detection signal 6,
This is a door opening relevel command generating device which outputs a door opening relevel command 9 to the door opening relevel control device 5 only when the floor shift detection signal 7 and the handicapped call detection signal 8 are input and all of these three conditions are input.

The operation of the apparatus of the present invention constructed as above will be described below. When a floor shift occurs due to passengers getting on and off while the elevator is stopped, the door open detection signal 6 and the floor shift detection signal 7 are input to the door open relevel command generator 4. In the conventional door opening releveling device, when these two conditions are input, the door opening releveling command 9 is output to perform the door opening releveling, but in the device of the present invention, the door opening releveling signal 8 is not input unless the disabled call detection signal 8 is input. Since the re-level command is not output, the door-open re-leveling is not performed when only general calls are made, and the door-opening re-leveling is performed only when a call for persons with disabilities is registered.

[0006]

FIG. 2 is a diagram showing the construction of an embodiment of the present invention. 3 shows a flowchart of software executed in the microcomputer shown in FIG.
In the figure, 11 is a door switch that detects the degree of opening of the door, and outputs a door open detection signal 6 when all the doors are open. Reference numeral 12 is a landing switch for detecting the floor landing position of the car, and outputs a floor misalignment detection signal 7 when the car is displaced from the landing position due to passengers getting on and off. Reference numeral 13 is a call button for the handicapped provided separately from the general call button.
Is output. A microcomputer 14 executes the processing shown in the flowchart of FIG. Reference numeral 15 denotes an elevator drive device that raises or lowers the elevator when it receives a door opening releveling command 9 from the microcomputer 14 to perform floor alignment.

The operation of the embodiment of the present invention configured as described above will be described below. The microcomputer 14 inputs a door open detection signal, a floor shift detection signal, and a handicapped call detection signal from a door switch, a landing switch, and a handicapped call button to perform the processing shown in FIG. Therefore, when the elevator is in the door stop state and a floor shift occurs due to passengers getting on and off, if the call for the disabled is registered, the door open relevel command is output and the door open relevel is executed. If the handicapped call button is not pressed, the door open relevel command is not output and the door open relevel is not executed even if the floor is displaced.

[0008] Therefore, if there is a call for people with disabilities, the door open relevel is carried out so that the wheelchair is easy to get on and off. On the contrary, if there is no call for people with disabilities, the door open relevel is not carried out. Moreover, since the door-open releveling operation is not performed, the elevator can start running as soon as the passengers have finished getting in and out, and the loss time is reduced.

[0009]

According to the present invention, even when the elevator is equipped with a door opening releveling device that corrects a floor shift caused by getting in and out of passengers, the door opening releveling is not executed when a general passenger gets in and out, thereby reducing the loss time. It is possible to reduce the number of elevators and improve the operating efficiency of the elevator. Also,
When people with disabilities get on and off, it is possible to easily get on and off in a wheelchair by executing the door-open releveling. In particular, the effect of the present invention is remarkable in a hydraulic elevator in which a car is largely lifted and dropped when passengers get on and off. INDUSTRIAL APPLICABILITY As described above, the present invention can provide an elevator control device having both elevator operating efficiency and practicality.
