Abstract

The invention provides a positioning method of a pipeline robot. At least one pipeline antenna device is installed on the pipe wall of a pipeline, the pipeline antenna device is partially installed onthe inner wall of the pipeline and partially installed on the outer wall of the pipeline, the pipeline antenna device comprises a control module, a light receiving and transmitting module, a positioning module and an antenna, the control module is connected with the light receiving and transmitting module and the positioning module, the positioning module is connected with the antenna, the antenna penetrates through a soil layer and is exposed out of the ground, and the light receiving and transmitting module is installed on the inner wall of the pipeline. The pipeline robot acquires positioninformation from the pipeline antenna device. According to the positioning method of the pipeline robot, low-error positioning of the pipeline robot is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline robots, in particular to a positioning method for pipeline robots. Background technique [0002] The pipeline robot moves in the pipeline, which involves the positioning problem of the pipeline robot. Some pipeline robot positioning methods use motion speed and time positioning, and long-distance motion is prone to positioning errors. A positioning method for pipeline robots is needed to realize low-error positioning of pipeline robots. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and propose a positioning method for pipeline robots by using the position information provided by satellite location services, so as to realize low-error positioning of pipeline robots. [0004] Specifically, a positioning method for a pipeline robot, including: [0005] Step 1) Install at least one pipeline antenna device...
