Guide rail positioning method and device thereof based on bar code technology

Abstract

The invention relates to a guide rail positioning method based on a bar code technology and a device thereof. The method comprises the following steps that operating parameters of a moving trolley areinput into an industrial personal computer interface, the industrial personal computer transmits the parameters to a first functional module, the first functional module processes and calculates thespeed actually required by the moving trolley in operation and the engineering unit of the actual position of a bar code to control the moving trolley to operate on a guide rail, meanwhile, a bar codereading head arranged on the moving trolley is driven to read a bar code belt and transmit the position information of the moving trolley back to the first functional module, and the first functionalmodule calculates the real-time interpolation position and the dynamic acceleration of a servo motor in the moving trolley according to the position information of the moving trolley to finish accurate repeated positioning. Compared with the traditional encoder positioning system, the invention has the advantages that the identification of the actual position is more accurate, the repeated positioning is more accurate, and the starting, stopping, accelerating and decelerating are smoother.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a guide rail positioning method based on barcode technology and a device thereof. Background technique [0002] As an indispensable part of the stage facilities of the theater, the moving trolley generally uses a servo positioning system to complete its precise and repetitive positioning. The traditional servo positioning system consists of a console, an encoder, a servo driver and a servo motor. [0003] In the patent application document with the patent document number CN201410140669.0, a servo positioning control system is disclosed, including a position loop control unit, a position command receiving unit, a command margin calculation unit and an interpolation displacement calculation unit: the position command The receiving unit is used to receive the position command from the host computer with the communication cycle T; the command margin calculation unit is used to it...
