Problems solved by technology

Although the existing uniform point distribution method can achieve the effect of uniform distribution, its distribution is disordered and there is no specific layout level and law. If an orderly and uniform point distribution method is adopted, the spherical space of the spherical internal detection instrument Point layout, spherical shell manufacturing and processing, programming application and maintenance bring great help, improve detection efficiency and enhance detection effect

Embodiment Construction

[0023] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0024] Taking a spherical instrument with a radius of r as an example, it is required that the total number of distribution points (total number of sensors) on its outer surface is about 150, and they can be evenly and orderly distributed on the spherical outer surface. The specific method steps are as follows:

[0025] (1) Set the center angle angle deviation c and calculate the number of layers N φ

[0026] Set the center angle deviation c as According to the formula (1) to calculate the number of layers N φ The range is N φ ∈[8.5,+∞), take N φ is 12, then the spherical space is evenly distributed with 12 layers of points in the range of elevation angle φ∈[0,π], that is, the spherical surface is divided into 11 parts, and the elevation angle of the part between each layer is

[0027] N φ ≥π / 2c+1 (1)

[0028] (2) Calculate the number of points per...

Abstract

The invention relates to a method for uniformly distributing points in a spherical space of a spherical internal inspection instrument in an ordered manner. The objective of the invention lies in that the method can improve the efficiency of design and manufacture. The technical scheme of the invention is that the method comprises the following steps: (1), setting an angle deviation c of a spherical sector and calculating the layer number (shown in the description) of point distribution; (2), calculating the number (shown in the description) of points of each layer; (3), obtaining the spherical coordinates of all points and the total number of points; (4), designing and manufacturing a spherical housing or a spherical structure according to the layout of the points.

Description

technical field [0001] The invention relates to a method for arranging points in a spherical space, in particular to a method for evenly and orderly arranging points in a spherical space for a spherical internal detection instrument. Background technique [0002] Internal detection technology is a cutting-edge and effective detection technology for detecting the internal conditions of objects or equipment, discovering and solving problems in time, and ensuring the normal operation of equipment. At present, this type of technology has been applied to the internal detection of crude oil storage tanks, natural gas pipelines, submarine pipelines and other equipment. Due to the considerable technical difficulty of internal detection, although it has been extensively studied, there are not many devices and methods that can achieve effective detection, or the price is expensive, or there are various difficulties in application. [0003] The spherical internal detection instrument ...
