Problems solved by technology

And because long-distance water pipelines are generally composed of underground closed pipelines, traditional GPS positioning equipment cannot be used for positioning and navigation. At present, this technical field is in a blank state. The more commonly used methods are: underwater robot positioning and navigation, underwater Positioning and navigation of robots combined with preset markers; large errors, complex construction procedures, and high construction costs

specific Embodiment approach

[0109] Step 801, the main control software designates the detection entrance of the water pipeline as the origin of the position, the main control software drives the unmanned submersible to place an acoustic tag No. 0 at the entrance of the water pipeline, and the main control software specifies the positive and negative directions of the pipeline. The following schemes have been specified The right side of the pipeline inspection entrance is described as the positive direction;

[0110] Step 802, the unmanned submersible enters the entrance of the water pipeline, starts to move, and performs fault detection operations. At the same time, the acoustic distance measuring device is turned on for distance measurement, so as to detect the distance between the current position of the unmanned submersible and the zero acoustic tag ;

[0111] Step 803, after the unmanned submersible enters the water pipeline, when the unmanned submersible moves to the right of the entrance of the wat...

Abstract

The invention discloses a fault marking method and device, a navigation method and device, electronic equipment and a storage medium, and the fault marking method comprises the steps that after a remote-control unmanned submersible enters a water conveying pipeline, the remote-control unmanned submersible detects the position of a first acoustic tag in an acoustic distance measurement mode; according to the first acoustic tag position, driving the unmanned submersible to reach the first acoustic tag position; the first acoustic tag is the position of a fault point; and according to the invention, the convenience of acoustic positioning navigation and the non-accumulation of errors are adopted, and accurate navigation guidance can be realized by using the acoustic tag without presetting a marker, so that the labor cost and the economic cost are reduced.

Description

technical field [0001] The invention relates to the field of detection of water pipelines, in particular to a fault mark, a navigation method, a device, electronic equipment and a storage medium. Background technique [0002] There are a large number of long-distance water pipelines in China, and the demand for fault detection and maintenance has become increasingly urgent in recent years. In this process, how to mark and quickly and accurately navigate to the fault sound mark point after finding the fault sound mark point for the first time has become one of the key points to improve the efficiency of fault detection and maintenance. And because long-distance water pipelines are generally composed of underground closed pipelines, traditional GPS positioning equipment cannot be used for positioning and navigation. At present, this technical field is in a blank state. The more commonly used methods are: underwater robot positioning and navigation, underwater The robot combin...
