Traction control system and method for positioning, calculating and correcting traction position

Abstract

The invention discloses a traction control system and a method for positioning, calculating and correcting a traction position. The system comprises a steel wire rope rotation wheel transmission system, a rail reciprocating vehicle and rotary encoders which are used for detecting the rotation positions of the steel wire rope rotation wheels; the rail reciprocating vehicle is provided with a permanent magnet; magnetic limit switches for sensing the permanent magnet are arranged on one side of a rail where the rail reciprocating vehicle runs; the rotary encoders and the magnetic limit switches output detection signals to a controller; and the controller is used for calculating the traction position according to the detection signals fed back by the rotary encoders, judging the running interval of the rail reciprocating vehicle according to the detection signals fed back by the magnetic limit switches and calculating and correcting the traction position to generate the current position of the rail reciprocating vehicle. By a double positioning detection mode that the rotary encoders are matched with the limit switches, the running position of the rail reciprocating vehicle is corrected and calculated, so that high positioning accuracy and strong reliability can be guaranteed, the structural design is simple, cost is low, and fault links are few.

Description

technical field [0001] The invention belongs to the technical field of traction systems, and in particular relates to an automatic control system that uses a wire rope runner drive system to drive a rail reciprocating vehicle and a method for calculating and correcting the traction position of the rail reciprocating vehicle based on the control system. Background technique [0002] In recent years, in some special applications, it is necessary to quickly drag large-tonnage items, and it is necessary to perform automatic control according to the position of the items during dragging, and finally automatically transport the items to the planned location. For the transportation of large-tonnage items, the traction and dragging of the reciprocating vehicle on the track by the wire rope runner transmission system is generally used at present, and the traction control system is used to detect the walking position of the reciprocating vehicle in real time, and then according to the...

Problems solved by technology

[0005] This kind of traction position detection method is only determined by the detection and calculation of the rotary encoder installed in the transmission system, so the probability of measurement error is relatively high, and problems such as untimely adjustment of the working state of the inverter often occur due to inaccurate position detection. , which has a certain impact on the safe and accurate delivery of items, and there are certain potential safety hazards
