The specific embodiment is as follows:
the invention is further described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, a tag recognition system for blood collection tube classification includes a tag 1 for recognition, a recognition terminal 2 for recognizing tag information, and a transmission system 3 for transmitting blood collection tubes 4;
The two adjacent sides of the label 1 are provided with identification starting point pixel strips 1a and 1b, the label 1 is also provided with a plurality of areas, and at least one area is filled with classification pixels 1c; the identification area is composed of a table with a certain number of grids, and when the label prints the blood test item to be tested, the direct printing is also printed out together with the identification starting point pixel strips 1a and 1b and the identification area preset and corresponding to the blood test item. The printing end is only required to set the templates corresponding to the blood detection items, or the starting pixel strips 1a and 1b can be printed on the labels when the labels are produced by the simplest adhesive, the setting is not required to be carried out when the labels are printed later, and the classification pixels 1c can be directly smeared in the corresponding areas by pens when the labels are not directly printed along with the blood detection items.
The identification terminal 2 comprises a PC, at least two camera input ends 2a and 2b connected with the PC, and a software end 2c installed on the PC, wherein the software end 2c comprises a dynamic identification mapping module 2d, an image processing module 2e and an output result module 2f; the dynamic identification and mapping module 2d controls the camera input ends 2a and 2b, the image processing module 2e receives the image input of the dynamic identification and mapping module 2d, the output result module 2f receives the feedback of the result of the dynamic identification and mapping module 2d from the image processing module 2e, the feedback result can be recorded by the software end 2c as information of each test tube, the information is displayed by the PC display device, or the high and low levels converted into serial ports or USB signals are output to the external processing device, the external device can be a screening mechanical structure, and the classification and screening are carried out on the blood collection tubes 4 transmitted by the transmission system by the classification information.
The transmission system 3 comprises a transmission mechanism for rolling the blood collection tube 4; comprises a groove cavity 31, a row of rolling belts 32 are arranged above the groove cavity 31 corresponding to a head cover 41 of the blood collection tube 4, a baffle 33 is arranged below the groove cavity 31 corresponding to blood collection tube equipment, and the baffle is fixed on a conveyor belt 34 synchronously driven above the groove cavity.
Of course, for the transmission mechanism, the invention mainly aims at enabling the blood collection tube 4 to pass through the camera in a rolling way, so that the camera can conveniently shoot and collect the label 1 attached to the surface of the blood collection tube 4.
The label is attached to the surface of the blood collection tube 4, the identification terminal 2 is arranged on one side of the conveying system 3, and the two shooting input ends 2a and 2b are used for shooting the label on the surface of the blood collection tube in an angle mode. The camera input end 2a is arranged to be opposite to the area where the general label of the blood collection tube 4 is adhered, and the angle between the camera input end 2b and the camera input end 2a is controlled within 60 degrees, and preferably 30 degrees.
The identification starting point pixel strips arranged on two adjacent side edges of the label 1 are longer and shorter, and intersect at the side edges of the label 1.
The classification pixel 1c region is provided with a recognition start point pixel bar near one side thereof.
The implementation principle of the invention is as follows:
because the label 1 is attached to the outer tube wall of the blood collection tube, the label 1 is an arc surface, the distance between the classification pixel 1c in the identification area and the identification starting point pixels 1a and 1b at the side edge of the label 1 is shortened, the straight line distance between the intersection point 1d of the 1a and 1b and the classification pixel 1c is A, and the set table is different in size, so that when the label 1 is flat, the sizes of the identification areas of the table x1 are changed in proportion along the y-axis to the p5 identification area in the directions indicated by x 1-x 5, y 1-y 5, z 1-z 5 and p 1-p 5 corresponding to the coordinates xyz shown in fig. 1.
Referring to fig. 3, in the case of such a ratio change, when the distance between the classification pixel 1c and the junction 1d of the identification starting point pixels 1a, 1B becomes smaller in proportion, the straight line distance B between the classification pixel 1c and the junction 1d of the identification starting point pixels 1a, 1B is shorter when viewed from the side by the camera input end 2B, especially when the label 1 is not very stuck on the wall of the blood collection tube, usually the label 1 is inclined a little like in the transmission system 3 of fig. 2 when being stuck manually, and the junction 1d of the identification starting point pixels 1a, 1B is also rapidly appeared in the camera input end 2B along with the rolling transmission of the transmission system 3 to the blood collection tube 4. The length of B is displayed in the camera input end 2B to be longer as the blood collection tube 4 continues to rotate according to the straight line distance from the classifying pixel 1c to the intersection point of the pixels 1a and 1B, when the length of B is1 unit and the length of the intersection point 1d to 1c is twice as long as the root number of the length of B, the running state identifying and mapping module 2d of the software end 2c in the PC controls the camera input end 2a to be placed right above the conveying system 3 from the blood collection tube 4 to perform mapping shooting, at the moment, the mapping shot in the camera input end 2a is conveyed to the image processing module 2e, the image processing module 2e calculates three points of the picture, namely the tail end of the identifying starting point pixel 1a with shorter length, the identifying starting point 1c of the starting point pixel 1a and the classifying pixel 1c, the tail end point of the identifying the starting point pixel 1a and the point 1d form reference coordinates, the distance of the classifying pixel 1c from the vector reference coordinates is calculated again, the corresponding distance of the intersecting point 1c from the vector reference coordinates is obtained, the blood is conveyed to the image processing module 2e, and the blood is conveyed to the blood collection tube 2f corresponding to the blood collection tube is recorded and the blood collection tube is conveyed to the blood collection tube 2.
The output of the category can be directly printed out to record the position, and the position can be extracted and classified manually and rapidly, and can also be connected with mechanical equipment to be automatically selected and classified with the mechanical equipment.
The length of B and the length of a are that the included angle between the input ends 2a and 2B of the camera is 60 degrees, such as 30 degrees, and then the length of B is controlled to be within five times of the root number of the length of a.
