Problems solved by technology

[0019] 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

Embodiment Construction

[0096] As shown in the figure, the present invention is based on the rail car positioning system of the rack and the encoder. The positioning system is installed on the rail car and moves with the rail car; Vehicles, encoders, PLC controllers, and motors installed on rail cars; racks are determined according to the number of work target positions, and each work target position is inlaid with racks with different numbers of teeth, and the length of the rack is determined by the inertia of the rail car and The adjustment range of the fine-tuning positioning depends on the adjustment range; the positioning system is installed on the side of the rail car, and the positioning system is equipped with gears, and the rack is installed on either side of the rail car's walking rail. The movement of the car rotates, and the rotation of the gear drives the encoder to rotate through the coupling to generate a pulse signal. The pulse signal is transmitted to the PLC controller. Through this ...

Abstract

The invention relates to a railway car positioning system and method based on an encoder and racks, particularly relates to a positioning system based on the encoder and the racks, and the positioning system can control a non-adjustable-speed motor to achieve high-precision positioning. The invention provides the railway car positioning system and method based on the encoder and the racks, and the system and the method are accurate in positioning and are short in positioning control time. The railway positioning system based on the encoder and the racks includes a railway, and a railway car is arranged on the railway. The structural features of the railway positioning system are that: a plurality of racks are arranged on the railway in the railway length direction; the numbers of teeth of all the racks are different; one rack is corresponding to one work target position; the railway car is provided with a gear which is engaged with the racks; the center shaft of the gear is connected to a rotatable signal input end of the encoder arranged on the railway car; and a signal output port of the encoder is connected to a signal input port of a PLC.

Description

technical field [0001] 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 [0002] 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. [0003] Analyze existing patents: [0004] (1) Invention patent name: automatic positioning device for traveling mechanism of mobile cleaning machine (application number: 201020692747.5) [0005] 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 installed as needed, and the cleani...
