Elevator car re-leveling control system and achieving method thereof

Abstract

The invention provides an elevator car re-leveling control system. The system comprises a logic control module, a driving brake module, a door detecting module and an elevator car position detecting module. The door detecting module is arranged on an elevator car door and used for detecting the opening or closing state of the elevator car door. The elevator car position detecting module is arranged on the outer side of an elevator car and used for detecting the position of the elevator car. An output end of the door detecting module and an output end of the elevator car position detecting module are electrically connected with an input end of the logic control module. The logic control module is electrically connected with an input end of the driving brake module. The driving brake moduleis arranged on an elevator tractor. According to the elevator car re-leveling control system and an achieving method thereof, the position of the elevator car is precisely positioned by means of the elevator car position detecting module, the logic control module controls the driving brake module according to positioning information, accordingly, the elevator operating speed and direction are controlled, the position of the elevator car is adjusted, the elevator car re-leveling position is adjusted correctly, and the elevator using safety is improved.

Description

technical field

[0001] The present invention relates to the technical field of elevator control, more specifically, to an elevator car re-leveling control system, and also to an implementation method of the system. Background technique

[0002] When the elevator is in daily use, the traction wire rope will be elastically stretched or shortened due to the change of the load after the car is leveled. Generally, the elevator can run to the leveling position by re-leveling, and the elevator judges that it needs to be re-leveled. The method of starting is to judge by the upper and lower photoelectric switches and the magnetic isolation plate. When one of the photoelectric switches is separated from the magnetic isolation plate, the elevator will judge that it needs to be started again until the two photoelectric switches are within the magnetic isolation plate. The accuracy of this method for judging the leveling position of the car is not high, and there is a certain potential s...
