It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Fig. 1 is a dual polarized tag antenna patch for logistics management according to the present application, comprising a stack of layers from bottom to top:
An adhesive coating for adhesively securing the dual polarized tag antenna patch to a surface of a logistics good;
An intermediate dielectric layer 1, which is rogers4350 dielectric substrate and covers the upper surface of the adhesive coating;
the metal radiation layer 2 comprises a plurality of symmetrically arranged radiation units and a tag chip 3 connected in the middle of the radiation units, wherein the radiation units can be C-shaped radiation units, and the transmission and radiation of positioning signals in two polarization directions are realized through the coupling between the C-shaped radiation units in two mutually perpendicular directions respectively;
and the reflecting composite layer at least covers the upper surface of the metal radiating unit 2 and is rogers4003C plate.
In order to ensure that each metal radiating element 2 is accurately coupled to a required frequency point, each C-shaped radiating element can be specifically provided with two parallel first polarization arms and two second polarization arms which are vertically connected to the end parts of the same side of the first polarization arms, and the first polarization arms and the second polarization arms are connected to form a C shape. An axis parallel to the length direction of the second polarization arm is used as a symmetry axis between the two C-shaped radiation units to form an I-shaped coupling unit, and a coupling gap parallel to the length direction of the second polarization arm is arranged in the middle of the I-shaped coupling unit; the I-shaped coupling units are arranged at equal intervals to form a coupling matrix, and first polarization arms of the four C-shaped radiation units positioned in the geometric center of the coupling matrix are respectively and electrically connected with the terminal pins of the tag chip 3. The coupling matrix can thus be fed through the first polarization arm in the geometric center, so that radio frequency signals are correspondingly received and positioning signals with the identification code corresponding to the tag chip 3 are radiated outwards according to the feedback signal of the tag chip 3.
To achieve better radiation characteristics, the application can select rogers4350 dielectric substrate with thickness not exceeding 1.6mm, and limit the size of the antenna to be as follows through rogers4350 dielectric substrate: the length and/or width is not more than 4 times the operating wavelength lambda of the dual polarized tag antenna patch. Therefore, the C-shaped radiating units can realize feeding through a near-field coupling mode, and radiate positioning signals in a specific polarization direction outwards through gaps among the C-shaped radiating units.
In cooperation with the rogers4350 dielectric substrate, the length and width dimensions of the reflective coating layer are set to be the same as those of the rogers4350 dielectric substrate, and the thickness of the reflective coating layer is set to be not more than that of the rogers4350 dielectric substrate so as to adjust the radiation angle range of the antenna through the dielectric constant of the rogers4350 dielectric substrate and the thickness matched with the patch working wavelength lambda of the dual-polarized tag antenna.
For the logistics goods adhered with the dual-polarized tag antenna patch, the application can be specifically positioned in the following way:

and a4, respectively marking and recording the transmission direction and the position node information corresponding to the positions of the transfer paths.
According to the training recording mode, the transmission path loss conditions corresponding to the transmission of the radio frequency signals from different positions in the logistics transmission area can be automatically matched, and the corresponding transfer path positions are identified by integrating the signals received by different radio frequency antennas. In order to ensure the accuracy of the positioning of the logistics goods, the method can set the period t of the condition of tracking, recording and positioning signal intensity to be not longer than the longest time corresponding to the movement of the test goods driven by the transfer path by 5m under ideal conditions. Thus, the deviation of the transfer path position matched by the positioning signal feature vector can be within 10m before and after the actual position. The on-site staff can conveniently and quickly identify and position the logistics goods which need special attention, and maintenance operations such as righting, cleaning and the like can be performed.
In order to further automatically identify whether the logistics goods are toppled, in the step a4, the following data are further recorded, so as to judge whether the logistics goods are overturned or not through calculating the radio frequency signal transmission distance between the logistics goods and the radio frequency antenna:
Step a4-1, establishing a positioning signal characteristic vector according to the positions of the test cargoes on each transfer path Respectively calculating distances between the test cargo and each radio frequency antenna as D1', D2', D3', D4';
And a step a4-2, establishing and storing a mapping relation between the positions of each transfer path and the distance between each radio frequency antenna.
Therefore, in the process of tracking the logistics goods, the interference and influence of dumping of the logistics goods on the transmission path of the radio frequency positioning signal can be further identified in the third step through the following steps, so that abnormal postures of overturning, overturning and the like of the logistics goods are identified:
