Abstract

The invention relates to a device and a method for distance positioning and mileage calibration of a railway robot. The device comprises I-shaped steel rails, the robot, lifting lug seats, a proximity transducer, a mileage computing device and a motor shaft encoder, wherein the proximity transducer is arranged on the robot; the lifting lug seats are arranged on operating rails; when the robot walks on the rails, the proximity transducer can detect position information of each lifting lug seat when passing the lifting lug seat; an accurate position and mileage information of the robot can be calculated by calculation of the mileage calculating device of the robot. The mileage of the mileage computing device is calibrated by using accurate and fixed positions of the lifting lug seats; the distance between the two lifting lug seats is computed by using the motor shaft encoder; the mileage and the distance are combined together to obtain an accurate position and a walking distance of the robot; the device is simple in structure and is accurate in positioning.

Description

technical field [0001] The invention relates to the field of orbital robots, in particular to a distance positioning and mileage calibration device and method for an orbital robot. Background technique [0002] Hanging rail robots are more and more widely used in industrial sites with harsh environments, especially for rail inspection robots. In order to ensure the accuracy of robot information collection, the robot needs to be constantly positioned and mileage calibrated. Existing robot positioning mainly includes infrared positioning, laser ranging positioning, GPS positioning, ultrasonic positioning, RFID positioning, etc. Among them, pure infrared positioning and laser ranging positioning are greatly affected by the intensity of infrared light in the environment, and in the presence of environmental information. Changes (such as obstacles on the work site) are likely to cause positioning errors, and are easily affected by dust and particles in the environment; ultrasonic...
