Problems solved by technology
However, this method requires that the length of each layer of boards must be consistent, and it is impossible to adjust different boards, and this algorithm is only applicable to solid boards, not suitable for boards with complex structures, such as regular Notched code board, so the currently applicable control method using leveling board cannot be applied to this kind of code board

The embodiment of the present invention relates to the field of elevator control, and discloses a control method and control system using leveling boards, including: dividing the leveling boards of each floor in the hoistway into several code segments, and according to the structure of the code segments The code segment is coded; according to the position of the car, the position of the leveling switch on the car is obtained; according to the reference position of the floor where the car is currently located and the length of the code segment, the absolute position of each code segment in the hoistway is obtained, Among them, the reference position of the floor in the hoistway is consistent with the center position of the leveling board; when the position of the leveling switch is located in the absolute position of each code segment and the code of the code segment is the specified code, the leveling switch control is output respectively. signal, the control method of the embodiment of the present invention encodes the structure of various leveling boards, and outputs control commands by judging the positional relationship between the leveling switch and each code segment, and accurately realizes the various leveling boards in the hoistway system. Applications.
Description
technical field [0001] The embodiments of the present invention relate to the field of elevator control, in particular to a control method and a control system using a leveling board. Background technique [0002] In the shaft of the elevator, a leveling plate needs to be installed in a certain area of each floor. The leveling plate is generally a rectangular solid iron plate. When the two leveling switches on the car run to the leveling When entering a shift, it is considered that the elevator car has run to the leveling position of the floor. Among them, the photoelectric switch is generally U-shaped, and the two arms of the switch emit light while receiving light. When the car moves to the leveling area, the light path is blocked by the light plate of this layer, the light path is disconnected, and the electrical signal can be transmitted to the main body. Control board, the main control board can judge whether the current elevator has reached the leveling area accordi...
