Detailed Description
For a better understanding of the objects, structure, features, and functions of the invention, reference should be made to the drawings and detailed description that follow.
As shown in fig. 1 and fig. 2, a radio frequency identification terminal 100 according to an embodiment of the present invention is provided, where the radio frequency identification terminal 100 mainly includes a directional antenna module 1, a camera 2, a display screen 5, and a control unit 4.
As shown in fig. 3, the directional antenna module 1 is designed to receive signals through a plurality of different receiving ranges a (a '), and the different receiving ranges a (a') are all precisely determined to be of a known shape, and the shape can be adjusted to be a regular shape, such as a circle or an ellipse, according to the requirement through a certain technical means. The directional antenna module 1 may be an array antenna or a combined antenna, etc., with adjustable radiation angle or maximum radiation direction X, so that the receiving range a (a ') of the directional antenna module 1 may be adjusted as required, and the directional antenna module 1 is preferably a phased array antenna, so as to achieve precise control of the radiation angle and the maximum radiation direction X of the directional antenna module 1, thereby achieving precise control of the receiving range a (a') of the directional antenna module 1. In this embodiment, the directional antenna module 1 is both a transmitting antenna and a receiving antenna, and according to the reciprocity theorem of the antennas, the radiation range of the directional antenna module 1 as the transmitting antenna is the same as the receiving range a (a') of the directional antenna module as the receiving antenna; in other embodiments, the directional antenna module 1 may be only a receiving antenna, so that a transmitting antenna may be additionally provided.
As shown in fig. 3 and 4, the camera 2 is configured to acquire an image of an area P to be read, an optical axis L of the camera 2 is coaxially disposed or disposed in parallel with a maximum radiation direction X (or a maximum receiving direction) of the directional antenna module 1, and a receiving range a (a') of the directional antenna module 1 is located in a field of view FOV of the camera 2, so that all articles 8 readable by the directional antenna module 1 are located in the field of view FOV of the camera 2. In other embodiments (not shown, the same applies below), the optical axis L of the camera 2 may form an angle with the maximum radiation direction X of the directional antenna module 1.
As shown in fig. 1 and 5, the display screen 5 is a touch screen, a display area 51 is provided on the display screen 5, the display area 51 is shown on the display screen 5 by lines, so as to form a display frame, an image of a region P to be read acquired by the camera 2 is displayed on the display screen 5, the shape of the display area 51 is artificially set, so that the display range of the display area 51 is approximately overlapped with the receiving range a (a ') of the directional antenna module 1, and since the receiving range a (a ') is adjustable, the display area 51 is set to be changed according to the change of the receiving range a (a '), so that the display area 51 and the receiving range a (a ') are always approximately overlapped, the invisible receiving range a (a ') is visually displayed through the display area 51, so that the user can clearly identify the reading range of the rfid terminal 100. The display screen 5 is for operation by a user to select an item 8 in the image. Specifically, the rfid terminal 100 may establish an image library of a plurality of objects to be identified 8 through a deep learning neural network, and store the image library in the storage unit 6 for the control unit 4 to call. When the camera 2 acquires the image of the region P to be read and displays the image on the display screen 5, and when the user selects an article 8 in the image, such as clicking or selecting a certain article 8 in the image, the control unit 4 compares the image of the article 8 selected by the user with the image library in the storage unit 6 through the deep learning neural network to identify the article 8 selected by the user. Then, the control unit 4 displays information of the similar item 8 of the item 8 selected by the user in the signals received by the directional antenna module 1 on the display screen 5. For the object 8 in the image, the outline of the object 8 can be automatically outlined through an image recognition algorithm, and the process is similar to the face recognition process when the current smart phone takes a picture, namely, when a camera discriminates a face, a square box is automatically generated to track the face; similarly, in this embodiment, after the camera 2 acquires the image of the article 8, the control unit 4 automatically outlines the article 8 according to the image recognition algorithm, and a user can conveniently click (or select by frame, etc.) the outline region of the corresponding article 8, that is, the article 8 can be selected; or, the user clicks (or frames, etc.) one of the articles 8, the algorithm automatically identifies the article 8 clicked (or frames, etc.) by the user, and automatically selects all similar articles 8 of the article 8 clicked by the user in the image, so that the method is more intelligent.
Referring to fig. 2 again, the control unit 4 is triggered by a trigger key 3 to control the directional antenna module 1 to transmit or receive signals and control the camera 2 to capture images.
In one embodiment (not shown, the same applies below), a user may manually operate on the display screen 5 to frame an image of an article 8 in a certain area, which corresponds to the article 8 in the corresponding area in the area P to be read, and then the control unit 4 adjusts the receiving range a (a') of the directional antenna module 1 according to the range of the article 8 selected by the user, so that the two are matched, so that the directional antenna module 1 only reads the article 8 selected by the user, or so that the directional antenna module 1 only reads other articles 8 on the display screen 5 besides the article 8 selected by the user. Thereafter, the display screen 5 further displays information on the article 8 selected by the user, or displays information on other articles 8 excluding the article 8 selected by the user
In another embodiment (not shown, the same applies below), the display screen 5 is configured to be operated by a user to select the first area 52 and the second area 53 in the image, and the rfid terminal 100 further reads the information of the article 8 in the intersection area or the union area or the remainder area of the first area 52 and the second area 53 according to a preset setting. The intersection region refers to a region where the first region 52 and the second region 53 intersect (overlap), the union region refers to a region where the first region 52 and the second region 53 are merged together, and the remaining union region refers to a region of the first region 52 excluding the second region 53 or a region of the second region 53 excluding the first region 52. Which area in the intersection area or union area or residual area is specifically read can be preset as required. Of course, other areas outside the intersection area, union area, and remainder area may also be read by presetting. The control unit 4 further adjusts the reception range a (a') of the directional antenna module 1 to read the item 8 information in the corresponding area. The display screen 5 then displays the information of the item 8 read.
In another embodiment (not shown, the same applies below), the directional antenna module 1 reads information of all articles 8 displayed on the display screen 5 in advance, and after the user selects the target article 8 by the manner in the previous embodiments, the control unit 4 screens out information of the corresponding article 8 received by the directional antenna module 1 according to the article 8 selected by the user, and further displays the information on the display screen 5.
