and 4, the printing equipment prints the target information sheet according to the judging result and attaches the target information sheet to the target. .

In one embodiment, in the method, the intelligent warehouse grid model is established according to different warehouse types, so that the number of row level nodes, array level nodes and column level nodes of the shelf is set, and the position of each material is recorded as: (Z, X, Y);

wherein Z is the number of nodes of the array level and represents the number of shelves;

x is the number of row level nodes and represents the number of rows on the Z-th shelf;

y is the number of column level nodes and indicates the X row and column on the Z-th shelf.

Specifically, the same number of grid models are set according to different numbers of warehouses, and the difference is that the shelf models in each warehouse are divided into two parts of a shelf list and shelf information, wherein the shelf list part can clearly show the distribution and the state of the shelf, and the shelf state is represented by three states in occupied, idle and maintenance and different colors; the shelf attributes include shelf ID, shelf specification and shelf status; the specification of the goods shelves is correspondingly designed according to different types of goods, so that the numbers of row-level nodes, array-level nodes and column-level nodes of the goods shelves in different types are different;

more specifically, when each printing operation is performed, the position of the target needs to be found first, the system compares the current target position with the next target position information, so as to determine whether the action of the next target needs to return to the initial place, and therefore the complexity of the operation is effectively reduced; the method comprises the following specific steps:

inputting a current target position (Z, X, Y) and a next target position (Z1, X1, Y2);

judging whether the number of node numbers (Z and Z1) of the current target position array is consistent with that of node numbers of the next target position array, if so, returning to the initial place is not needed, otherwise, returning to the initial place is needed;

The receiving and transmitting printing target information is to carry out independent communication and data transmission according to a communication network arranged in each warehouse, and each warehouse and the control center form a network node so as to form network communication of a tree structure.

In one embodiment, each network node is encoded with a communication address, and the target information is transmitted in the form of a data packet; meanwhile, the control center is used as a master node to control the communication rhythm and process of the whole network, other nodes are slave nodes, and corresponding transfer is carried out according to the command of the master node; when in communication, the master node firstly transmits a data packet, wherein the data packet comprises the address of a called node;

specifically, the specific steps of the data transmission are as follows:

firstly, initializing a system;

initializing a wireless module and initializing serial communication, judging whether the serial port receives interruption (namely judging whether the serial port control command from an upper computer is received) or not, if yes, clearing an interruption mark, judging whether to set a slave serial number command, inquire the slave serial number command or read a slave data command according to the command, if one of the commands is the slave serial number command or the slave data command, requesting a package according to a command format by a host, transmitting the package to the slave through the wireless module, and waiting until the host is transmitted completely

Packaging and transmitting data; setting a packet header (packet header data refers to the position of a warehouse) of the target information, determining the length according to the data type, and determining the last data as a packet tail, thereby finishing packaging; and meanwhile, encoding the packed data, and converting the data packet into a code stream to be sent.

More specifically, the host sends the data packet to each slave, and the slave receives the code stream data packet, decodes the code stream, and extracts the information of the data packet, thereby obtaining the position information and other information of the target; the method comprises the following specific steps:

receiving code stream data output by a host;

receiving a code stream and sending a cache reset signal;

decoding the code stream; resetting the received buffered reset signal; if the reset is invalid, indicating that the code stream data is accurate, decoding the code stream according to the time sequence requirement; if the reset is valid, indicating that the code stream data is wrong, resetting the cache and clearing the data, and discarding the decoding;

the decoded data is sent to a designated printing system in the warehouse.

In one embodiment, the confirmation of the consistency of the target information is to receive the data packet through the printing system to read the internal printing target information and transmit the information to the printing device, so that the printing device drives to the target position, scans the goods number on the target, and performs matching with the target data in the database, thereby confirming whether the target is identical to the target to be printed according to the matching result, and outputting the result.

In a further embodiment, confirming that the target information is consistent comprises the steps of:

collecting and processing images; acquiring a label picture on the target goods, and processing the acquired picture, so that the integrity of information is ensured;

performing bar code identification on the label; measuring the widths of the statistical bars and the empty on the image, wherein the unit is the number of pixels, and then calculating the codes according to the width of the unit module;

extracting information from the tag; measuring all the strip and empty width data of the label image which completes the coding work, and obtaining a numerical sequence;

obtaining a target position relation according to the corresponding numerical value sequence and verifying whether the target position relation is consistent; a checksum may be used for each recognized data character to verify that the recognition was incorrect;

and outputting a result.

Specifically, the image is collected and processed; the method mainly processes the acquired original image, and restores distortion phenomena such as deflection, noise and the like caused by data generating 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 the image preprocessing has a considerable influence on the identification effect;

the invention mainly uses a neighborhood processing method to enhance the image, firstly, the gray level conversion of the image is carried out, the gray level conversion is to replace three components by one quantity, and the quantity has certain relativity with the three components and is used for eliminating the color difference of the image, so that the image only has the brightness difference; the RGB sub-table represents the color values of the three components of red, green and blue of the pixel, and the three components are converted according to a certain proportion by the color image of the acquisition set, so that the color image is converted into a gray image; the pixel of the converted image is the gray value of the pixel after gray conversion;

in practice, the blurred noise generated by image acquisition is basically Gaussian noise, and detecting the edges of the bar code under the condition of blurred edges can have a great influence on the determination of the bar space width of the bar code, thereby influencing the identification. Therefore, the edge blurring is an important factor influencing the bar code recognition, and the removal of Gaussian noise is also an important step in the bar code image preprocessing process;

the Gaussian filtering is matched with binarization to process the picture, and the gray level histogram distribution of the bar code area is not bimodal in the actual environment due to uneven illumination in a warehouse, image noise interference and the like. The local thresholding method is commonly used for identifying images with severe interference or uneven illumination, so that the images need to be processed by matching with binarization; the method comprises the following steps:

taking one image selected from the target images as f (x, y), taking the (x, y) as the center, carrying out regional Gaussian filtering on the radius with the size of S, and obtaining f after filtering ¹ The image gray value of (x, y) is specifically expressed by the gaussian filter formula:

f ¹ (x，y)＝1/S ² ∑ _x，y f(x，y)*exp-(x ² +y ² /σ ² )/2。

wherein σ is a smooth scale;

further, a threshold T of the f (x, y) point is calculated:

T(x，y)＝f _max +f _min /2

f _max ＝f(x+k，y+l)

f _min ＝f(x+k，y+l)

-S≤k，l≤S

k and l are position parameters within the window;

calculating f after Gaussian filtering ¹ Threshold T of (x, y) point ¹ ：

T ¹ (x，y)＝f _max +f _min /2

Performing image binarization:

wherein b is the result of binarization at (x, y);

edge detection is used for obtaining left, right, upper and lower boundaries of readings through horizontal and vertical projection positioning of the readings of the ammeter after subsequent image inclination correction and binarization, and dividing digital characters;

when the printing device collects images, some bar codes always cause the images to incline due to the nonstandard mapping of staff, so that the images have certain inclination, if the inclination is smaller, the subsequent recognition results are not affected, but once the inclination of the images is larger, the subsequent image processing and recognition are greatly affected; in order to solve the inclination of the image, a standard image frame is input first, then an included angle is formed on the image, and then the inclination angle of the acquired image is obtained, and correction is carried out according to the absolute value of the inclination angle.

More specifically, the bar code recognition of the tag is divided into two steps, namely, the reading of numbers under the bar code and the recognition of the bar code, and the following specific steps are given:

firstly, reading numbers under the bar code, finding out 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; and according to the length and width of the number, acquiring horizontal lines of one quarter and three quarters of the number from top to bottom, and recording the number of intersections respectively if the number characters intersect. Then taking a digit perpendicular bisector from top to bottom, judging whether the digit perpendicular bisector intersects with the digital character, recording the number of intersections, and obtaining a digit according to the number of intersections;

the identification of bar codes is carried out, firstly, the longitudinal coordinate of each sample line is determined according to the height of the image and the number of sampling lines, and the image is scanned from left to right when each sample line is sampled; counting from the first black pixel point, using a mark to indicate the width of a black bar measured this time until a white pixel point is encountered, switching from black bar to empty occurs at this time, firstly storing the accumulated black bar width, then indicating the mark as a white bar, accumulating again after accumulating and emptying, and recording the next empty width of the black bar at this time. When the black-white switching is performed for 6 times, indicating that one character unit is measured, storing 3 blank widths of the character unit, and repeating the steps to continuously measure the next character; until the width of the complete image is scanned;

the information extraction of the tag is to search a corresponding database code table according to the calculated coding sequence after the measurement is finished so as to obtain specific information, which is called decoding; the former takes the average value of the width series obtained by calculation as the final measurement result, namely only looking at the whole; the latter firstly decodes from the population, and then decodes by using a single sample line if the failure occurs; the decoding is carried out from the first character to the last character in sequence, the decoding of the sample line fails only when one character fails in decoding, and the identification failure information is output when all sample lines do not give results;

and obtaining a target position relation according to the numerical value sequence and verifying whether the target position relation is consistent, specifically comparing the output bar code information with the received target 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 notifying a worker to check.
