Elevator control device

Abstract

The invention provides an elevator control device, which can stably perform driving operations including inverted running during the floor repositing operation regardless of the state of the elevator-floor height difference depending on the number of passengers on the elevator, thereby quickly eliminating the height difference in a minimum time. When an elevator car is stopped at a predetermined floor, under the condition that an elevator car floor height difference is generated, a control device (4) which controls the lifting of the elevator car (1) by controlling an elevator-car-used motor (3) controls the driving of the elevator-car-used motor (3) so as to perform the floor repositing operation, by this time, a stage speed control is carried out in a manner that, the speed of the floor repositing operation is increased if the elevator car floor height difference is large.

Description

technical field [0001] The invention relates to an elevator control device with the function of floor re-alignment operation. When the elevator car stops at a designated floor for operation, the elevator control device performs floor re-alignment when there is a difference in the height of the car floor. run. Background technique [0002] Elevator installations having a floor re-alignment function are known. In these elevator installations, when the elevator car is moved up and down between a plurality of floors of a hoistway provided in a building, When there is a difference in car floor height during the parking operation on the designated floor, the floor re-alignment operation is performed. [0003] For this reason, a position detection sensor that optically or magnetically detects the height difference of the car floor is provided at the specified position of the top outer wall of the elevator car and the specified position of each floor of the elevator passage. When ...

Problems solved by technology

However, it actually uses a correction value with a simple characteristic that the correction amount changes with a certain slope with the change of the car load, and performs operation control according to the characteristic that the running speed increases and decreases smoothly in proportion to the size of the distance. In the floor re-alignment operation, the factor that the state of the floor height difference will change due to the number of passengers getting on and off the elevator (for example, when a large number of passengers get on and off the elevator at once) is not considered, it is difficult to perform stably including reverse Drive action including operation

[0014] That is to say, in the existing elevator equipment, since the floor re-alignment operation is performed at a certain speed when the difference in height of the car floor occurs, or in a manner proportional to the size (distance) of the difference in height of the car floor The floor re-alignment operation is performed at a variable speed, so there is a problem that it is difficult to perform stable driving operations including reverse operation during the floor re-alignment operation, and it is difficult to quickly eliminate the problem of height difference
