specific Embodiment approach

[0015] detailed description: The present invention is further described below:

[0016] The invention provides a positioning method for rail car travel, the specific steps of the method are as follows:

[0017] (1) The rail car is driven by a stepping motor or a servo motor;

[0018] (2) On the track of the rail car, set a mark at every fixed distance, and the label of each mark is unique; the fixed distance can be set arbitrarily according to the needs of the use environment;

[0019] (3) Install a marker position recognizer on the rail car, and use the marker position recognizer to automatically read the label of the marker position when passing any marker position on the track;

[0020] (4) Calibrate the traveling distance of the trolley corresponding to one step angle per rotation of the stepping motor or servo motor. Since the stepping angle is fixed, the traveling distance of the trolley corresponding to one step angle per revolution is also fixed , we call the travel...

Embodiment 1

[0026] (1) The rail car is driven by a stepping motor or a servo motor;

[0027] (2) On the track of the rail car, set a marker position at an interval of 1m, and the label of each marker position is unique; the fixed distance can be set arbitrarily according to the needs of the use environment;

[0028] (3) Install a marker position recognizer on the rail car, and use the marker position recognizer to automatically read the label of the marker position when passing any marker position on the track;

[0029] (4) Calibrate the traveling distance of the trolley corresponding to one step angle per rotation of the stepping motor or servo motor. Since the stepping angle is fixed, the traveling distance of the trolley corresponding to one step angle per revolution is also fixed , we call the travel distance of the trolley corresponding to one step angle per revolution of the stepping motor or servo motor as the travel parameter, and determine the travel distance of the rail car acco...

Abstract

The invention provides a track car advancing locating method. According to the method, a stepping motor or a servo motor is adopted to control a track car, a mark position is set on a track, and the position of the track car and control parameters are determined by reading information of the mark position. The track car advancing locating method well solves the problems of inaccurate locating and inaccurate control of existing methods and greatly improves use accuracy of the track car, the track car can operate more smoothly and safely, use efficiency of the track car is greatly improved, and the track car can well complete an established task.

Description

technical field [0001] The invention relates to a control method, in particular to a positioning method for rail vehicle travel. Background technique [0002] The current rail cars have been used in many fields, but most of the control methods for rail cars are not ideal, because the current control methods are relatively backward, and many of them still estimate the position of the car based on visual inspection and the speed of the car, which will cause rail cars. The designated position cannot be accurately reached, and the position of the trolley cannot be adjusted according to the needs, so that the task that the rail car should complete cannot be well completed. Contents of the invention [0003] Purpose of the invention: The present invention provides a positioning method for rail car travel, and its purpose is to solve the unsatisfactory problem of the previous control method. [0004] Technical solution: the present invention is achieved through the following te...
