Rail car positioning system and method based on encoder and rack

Abstract

Rail car positioning system and method based on encoder and rack relates to a rail car positioning system and method based on encoder and rack, specifically an encoder and rack positioning system, which controls a non-adjustable speed motor to achieve method for high-precision positioning. The invention provides a rail car positioning system and method based on an encoder and a rack with accurate positioning and short positioning control time. The track car positioning system based on the encoder and the rack in the present invention includes a track on which a track car is arranged, and a plurality of racks are arranged on the track along the length direction of the track, and the number of teeth of each rack is different. The bar corresponds to a job target position setting, the rail car is provided with a gear meshing with the rack, the gear central axis is connected to the encoder rotation signal input end arranged on the rail car, and the signal output port of the encoder is connected to the PLC signal input port. The ports are connected.

Description

Rail car positioning system and method based on encoder and rack technical field The invention relates to a rail vehicle positioning system and method based on an encoder and a rack, in particular to an encoder and a rack positioning system and a method for controlling a non-adjustable speed motor to achieve high-precision positioning. Background technique In some engineering fields, a rail car controlled by electricity needs to locate multiple working positions. How to accurately position the rail car is the prerequisite for the rail car to perform precise operations. Analyze existing patents: (1) Invention patent name: automatic positioning device for traveling mechanism of mobile cleaning machine (application number: 201020692747.5) The invention patent is to install a proximity sensor and a proximity positioning sensor under the frame of the mobile cleaning machine, and set cleaning positioning points on the dam surface where the mobile cleaning machine is installe...

Problems solved by technology

In this patent, since the reflector is fixed at one end of the track, the laser rangefinder and the reflector need to be on the same straight line and the line must be parallel to the track. The ground collapse will directly cause the laser rangefinder to fail to receive data. inaccurate positioning
