Double-servo-motor control method for amusement facility track detection device

Abstract

The invention discloses a double-servo-motor control method for an amusement facility track detection device. Two motors are used for driving the driving wheels on the left and right sides respectively; wherein the servo motor I is a master motor, and the servo motor II is a slave motor; the servo motor II works in a torque mode; the output torque of the servo motor II is adjusted according to thecurrent feedback value of the servo motor I to enable current feedback values of the servo motor II and the servo motor I to be close, thereby ensuring close working states of the two and avoiding acompetitive phenomenon of the driving wheels on the left and right sides. The structure is simple, the method is high in response speed, high in reliability and good in flexibility, walking of the recreation facility track detection device can be effectively and stably controlled, and comprehensive track detection of the amusement facility track detection device is better achieved.

Description

technical field [0001] The invention relates to a control method of a servo motor, in particular to a method for controlling a double servo motor in a track detection device of an amusement facility. Background technique [0002] The track inspection device of amusement facilities realizes the functions of macroscopic inspection, wall thickness inspection and crack inspection of the track of amusement facilities by carrying cameras, ultrasonic thickness gauges, eddy current flaw detectors and other inspection instruments on the vehicles walking along the facility rails. [0003] The track of the amusement facility is usually two groups in parallel, and the left and right driving wheels of the vehicle travel along the track on the corresponding side respectively. When the traditional motor drive control method is applied to this type of rail vehicle, there are the following problems: Whether the left and right drive wheels are driven by the same motor through the differential...

AI Technical Summary

Problems solved by technology

When the traditional motor drive control method is applied to this type of rail vehicle, there are the following problems: Whether the left and right drive wheels are driven by the same motor through the differential transmission mechanism, or are driven independently by two motors, there will be mutual competition between the wheels on both sides The problem——that is, the relative motion state between the left and right wheels and the track is inconsistent, which eventually leads to the situation that the vehicle is unstable or even unable to walk normally, which seriously affects the detection work.
