Carrying out data packing and sending; setting a packet head (packet head data refers to the position of a warehouse) of target information, determining the length according to the data type, and determining the last data as a packet tail so as to finish packaging; and meanwhile, encoding the packed data, and converting the data packet into a code stream for transmission.

In a further embodiment, confirming that the target information is consistent comprises the steps of:
collecting and processing images; collecting a label picture on a target cargo and processing the collected picture so as to ensure the integrity of information;
performing bar code identification on the label; measuring, namely counting the widths of the bars and the spaces on the image, wherein the unit is the number of pixels, and then calculating codes according to the width of a unit module;
extracting information from the label; measuring all width data of bars and spaces of the label image which is coded, and obtaining a numerical sequence;
obtaining a target position relation corresponding to the numerical sequence and verifying whether the target position relation is consistent or not; for each recognized data character, a checksum can be used to verify whether the recognition is incorrect;
and outputting the result.
Specifically, the images are collected and processed; the method mainly comprises the steps of processing an acquired original image, and restoring distortion phenomena such as deflection, noise and the like caused by data generation equipment or other factors through technologies such as image transformation, inclination correction, filtering, binarization and the like, so that the method is more suitable for the next operation. In printing systems, preprocessing is a significant part of the basis for subsequent work; the quality of image preprocessing has considerable influence on the recognition effect;
the invention mainly uses a neighborhood processing method to enhance the image, firstly, the gray scale conversion of the image is carried out, the gray scale conversion utilizes a quantity to replace three components, the quantity has certain correlation with the three components and is used for eliminating the color difference of the image, so that the image only has the difference of brightness; the RGB sub-table represents color values of the red component, the green component and the blue component of the pixel, and the collected color image is converted into a gray image according to a certain proportion; the pixel of the converted image is the gray value of the pixel after gray conversion;
in practice, fuzzy noise generated by image acquisition is basically gaussian noise, and detecting the edge of a barcode under the condition of edge blurring has a great influence on determining the width of a barcode bar space, so that identification is influenced. Therefore, the edge blurring is an important factor influencing the barcode identification, and the removal of the Gaussian noise is also an important step in the preprocessing process of the barcode image;
for the gaussian filtering, the picture needs to be processed in cooperation with binarization, because in an actual environment, due to illumination nonuniformity in a warehouse, image noise interference and the like, the distribution of the gray histogram of the barcode region does not exhibit bimodality. The local threshold method is commonly used for identifying images with serious interference or non-uniform illumination, so that the images need to be processed in cooperation with binarization; the method comprises the following specific steps:
setting an image selected from the target image as f (x, y) and taking (x, y) asThe center, the radius with the size of S is processed with regional Gaussian filtering to obtain f1(x, y) image gray values, the specific gaussian filter formula is:
f1(x，y)＝1/S2∑x，yf(x，y)*exp-(x2+y2/σ2)/2。
wherein σ is the smoothing scale;
further, a threshold T at point f (x, y) is calculated:
T(x，y)＝fmax+fmin/2
fmax＝f(x+k，y+l)
fmin＝f(x+k，y+l)
-S≤k，l≤S
k and l are position parameters in the window;
f after Gaussian filtering1Threshold value T of (x, y) point1：
T1(x，y)＝fmax+fmin/2
Carrying out image binarization:
wherein b represents the result of binarization at (x, y);
the edge detection is to obtain the left, right, upper and lower boundaries of the reading through horizontal and vertical projection positioning of the reading of the electric meter after subsequent image inclination correction and binarization, and divide digital characters;
when the printing device collects images, some bar codes always incline the images because of the nonstandard chartlement of workers, and further the images have certain inclination, if the inclination is small, the subsequent identification result cannot be influenced, but once the inclination of the images is large, the subsequent image processing and identification are greatly influenced; in order to solve the problem of image inclination, a standard image frame is input firstly, an included angle is formed in the image, an inclination angle of the collected image is obtained, and correction is carried out according to the absolute value of the inclination angle.
More specifically, the barcode recognition of the tag is divided into two steps, namely, reading the number under the barcode, and recognizing the barcode, and the following specific steps are provided:
reading the numbers under the bar codes, firstly finding the frame of each number, and recording the numerical values of the maximum and minimum points of the edge point coordinates of the numbers in the picture; according to the length and the width of the number, horizontal lines at the positions of one quarter and three quarters of the number are acquired from top to bottom, whether the number characters are intersected or not is judged, and the number of intersection points is recorded respectively. Then, taking a central vertical line of the number from top to bottom, recording the number of intersection points if the central vertical line intersects with the number character, and obtaining the number according to the number of intersection points;
identifying the bar code, firstly determining the longitudinal coordinate of each sample line according to the height of the image and the number of the sampling lines, and scanning the image from left to right when each sample line is sampled; counting is started when a first black pixel point is met, a mark is used for indicating the width of a black strip measured at this time until a white pixel point is met, at this time, the black strip is switched to be empty, the accumulated width of the black strip is stored firstly, then the mark is indicated to be the white strip, the accumulated width is accumulated again after the accumulation is empty, and at this time, the recorded width is the next empty width of the black strip. When the black and white are switched for 6 times to indicate that one character unit is measured, storing the 3 empty widths of the character unit, and repeating the steps to continuously measure the next character; until the width of a complete image is scanned;
after the measurement is finished, searching a corresponding database code table according to the coding sequence obtained by calculation to obtain specific information, which is called decoding; in the invention, the average value of the calculated width series is used as the final measurement result, namely only the whole is seen; the latter decodes from the totality first, if fail then use the single sample line to decode; when decoding is carried out, the first character is sequentially decoded to the last character, the decoding of the sample line fails as long as one character is decoded unsuccessfully in the middle, and when all sample lines do not give results, identification failure information is output;
and obtaining a target position relation corresponding to the numerical sequence and verifying whether the target position relation is consistent, specifically, comparing the received target information with the output bar code information so as to judge whether the information is consistent, if so, printing a label and attaching the label to the target, otherwise, outputting a failure signal to a control system and informing a worker to check.
