Drawings
Fig. 1 is a schematic flow chart of a valve identifier management method and system according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, a valve identifier management method includes the following steps:
s1: the two-dimensional code of the valve is scanned, the valve management system is accessed to transfer the fault condition of the thermodynamic system, the valve mark at the position is started for warning, and the follow-up scanning system can immediately prompt that the valve at the position is overhauled;
s2: collecting and uploading a fault position of a thermodynamic system through mobile phone equipment, analyzing and preprocessing an uploaded fault image, and converting the fault image into another histogram with equalization through gray level conversion, namely, each gray level has the same number of pixel points;
histogram equalization transformation: let the gray scale transform s ═ f (r) be a slope-limited non-decreasing continuous differentiable function, which converts the input image Ii (x, y) into the output image Io (x, y), the histogram of the input image is hi (r), the histogram of the output image is ho(s), and then the corresponding small area elements after gray scale transform are equal according to the meaning of the histogram: ho(s) ds ═ hi (r) dr
The transformation function f (r) must satisfy the following 2 conditions:
(1) f (r) (0(r (1)) is a single valued function and increases monotonically;
(2)0(f(r)(1，(0(r(1)；
the first condition above ensures that the grey levels are in order from black to white and the second condition ensures that the grey levels of the transformed pixels are still within the allowed range. r ═ f-l(s) is an inverse transform function, and the above conditions are also satisfied;
according to the formula, the following results are obtained:
s2＝0.19+0.25+0.2l＝0.65，
s3＝0.19+0.25+0.2l+0.16＝0.8l，
s4＝0.89,s5＝0.95，s6＝0.98，s7＝1.00。
since only 8 equally spaced gray levels are taken here, the transformed s-value can also only select the value of the closest one. Therefore, from the above calculated values, one can approximately choose:
s0"1/7，s 1··3/7，s2··5/7，s3"6/7，
s4··6/7，s5··1，s6··l，s7··1。
it can be seen that the new image will only have 5 different grey levels, and we can then redefine its sign:
s'0＝l/7，s’1＝3/7，s'2＝5/7，s’3＝6/7，s’4＝l。
since r 0-0 is transformed and mapped to s 0-1/7, n 0-790 pixels take s0 gray value; mapping rl-3/7 from rl-3/7, so that 1023 pixels have s1 gray value; by analogy, 850 pixels take the gray value of s 2-5/7; since r3 and r4 both map to the gray scale value of s 3-6/7, 656+ 329-985 pixels take the gray scale value; similarly, the new histogram can be obtained by dividing s 4-1 by n 4096 for all the 245+122+ 81-448 pixels;
denoising the image and carrying out geometric transformation to change the spatial relationship between objects in the image;
performing affine transformation such as translation and stretching on the transformed image, correcting the image with geometric distortion, and establishing spatial transformation according to actual distortion data of the grid;
sorting the pixels in the neighborhood according to the gray level, and taking the middle value as an output pixel;
the gray scale transformation method is mainly divided into a linear transformation method and a piecewise linear transformation method;
linear transformation assumes the gray scale range of the source image as [ a, b ], and hopes that the gray scale range of the transformed image is expanded to [ c, d ], and linear transformation is carried out;
expressed as:
g(x,y)＝[(d-c)/(b-a)]f(x,y)+c
if the gray levels of most pixels in the image are distributed in the interval [ a, b ], and a very small gray level exceeds the interval, to improve the enhancement effect, the following steps can be performed:
piecewise linear transformation in order to highlight interesting objects or gray scale regions and relatively suppress those uninteresting gray scale regions, a piecewise linear method is often adopted, and generally, a three-segment linear transformation method is often used, and the mathematical expression of the method is as follows:
the image definition is improved, and the uniformity of the image space pixel values is balanced;
s3: extracting the features of the processed picture information to obtain feature data of a fault picture, and comparing the feature data with database data;
the Gamma correction method is adopted to carry out color space standardization on the input image, adjust the contrast of the image, reduce the influence caused by local shadow and illumination change of the image and inhibit the interference of noise;
the gradient of each pixel of the image is calculated, contour information is captured, and the interference of illumination is further weakened.
Dividing the image into a plurality of small units, and counting a gradient histogram of each small unit to form a descriptor of each small unit;
forming each small unit into a block, and connecting the feature descriptors of all the small units in one block in series to obtain the HOG feature descriptor of the block;
connecting HOG feature descriptors of all blocks in an image in series to obtain the HOG feature descriptors of the image, and obtaining a final feature vector available for analysis;
s4: calling fault maintenance operation in the current period database according to the comparison and discrimination result; transmitting the solution video of the corresponding scheme to a mobile phone end;
s5: if the corresponding operation is not detected, recording the self-running whole-course overhaul operation video through the mobile phone, and uploading the video to a database;
