A real-time positioning method and device for rail transportation equipment

Abstract

An embodiment of the present invention provides a method for real-time positioning of rail transport equipment, the method comprising: during the process of the transport equipment running back and forth along its track, synchronously photographing a fixed two Two-dimensional code positioning unit group, obtaining the real-time image of the two-dimensional code positioning unit group; according to the identification number and corner point data of each two-dimensional code on the real-time image of the two-dimensional code positioning unit group, the special image acquisition The external parameter data of the equipment and the identification number of the two-dimensional code corresponding to the starting position of the entire journey of the transportation equipment on its track, to obtain the actual position information of the center point of the special image acquisition equipment, that is, the real-time location of the transportation equipment information. According to the technical solution of the present invention, under the same external environmental conditions, the rail transportation equipment at the production site can not only operate normally and stably, but also reduce the use cost to the greatest extent in realizing real-time positioning.

Description

technical field [0001] The invention relates to the detection field, in particular to a real-time positioning method and device for rail transportation equipment. Background technique [0002] With the continuous development of information intelligence in the domestic manufacturing industry, especially in the iron and steel industry, how to effectively use new technical methods or new inventions to optimize and upgrade equipment that was outdated and costly to maintain has become a growing concern of steel enterprises. On the one hand, it can promote the development of intelligent manufacturing in the steel industry, and on the other hand, it can effectively reduce the cost of manpower and material resources. [0003] In view of this, as the common rail transportation equipment (such as driving, loading trolley, etc.) , RFID method, etc.: The laser ranging method is to emit a beam of laser light to the target during work, and the photoelectric element receives the laser bea...

AI Technical Summary

Problems solved by technology

The above positioning methods have the following characteristics: (1) Under ideal conditions, the measurement accuracy can reach millimeter level; (2) Laser ranging is easily interfered by environmental factors such as smoke, dust, raindrops; the installation cost of Gray bus is very high. High, the installation cost ranges from 1,000 to 3,000 yuan / meter; the encoder method is prone to hub slippage, causing misjudgment of positioning; the radar ranging method has a small measurement range and is difficult to maintain; the radio frequency identification method is not suitable for the harsh environment on site It is easy to collect dust, resulting in the accuracy of scanning codes, and it is easy to miss scanning
