Abstract

The invention discloses a control method of movement of a spherical detector in a pressure pipe. The advancing speed of a video ball is collected by an accelerometer inside the video ball, the flowing speed of water flow is controlled, the advancing speed of the video ball is made to be within the range of the maximum speed and the minimum speed, and control over the water flow flowing speed is formed; the buoyancy value born by the video ball is collected by a buoyancy sensor inside the video ball, whether the video ball meets the collision condition or not is judged through collected images, and comprehensive analysis and judgment are performed according to comparison of the weight of the video ball with the buoyancy value born by the video ball and the result of whether the video ball meets the collision condition or not so as to control flowing quantity of water flow. By means of the method, the optimal flowing speed and flowing quantity of the spherical detector in the detection process can be obtained. The advancing speed of the video ball in the pipe is effectively controlled by controlling the flowing speed and flowing quantity of water, and reasonable and effective shooting is performed.

Description

technical field [0001] The invention relates to the field of detection in a pressure pipeline, in particular to a motion control method for a spherical detector in a pressure pipeline, which controls the movement of the spherical detector in the pressure pipeline. Background technique [0002] Video ball detection of pipeline blockage and corrosion is a detection method for pressure pipelines. Since the video resolution is relatively high, if the detection pipeline is relatively long, the memory requirement for the video ball is relatively large. If the video ball advances too fast in the pipeline, there will be many blind spots; if it is too slow, it will cause repeated shooting in many places and consume too much memory. Contents of the invention [0003] In order to solve the problems existing in the background technology, the purpose of the present invention is to propose a motion control method for a spherical detector in a pressure pipeline, which can effectively co...
