Detailed Description
In the technical scheme provided by the embodiment of the application, the antenna array is arranged behind the touch screen and the display control module of the electronic equipment, so that the technical problem that the electronic label cannot be positioned on the screen when placed on the screen of the equipment in the prior art is solved, the positioning method of the electronic label is provided, and the technical effect of positioning the position of the electronic label on the screen is realized.
The main implementation principle, the specific implementation mode and the corresponding beneficial effects of the technical scheme of the embodiment of the present application are explained in detail with reference to the accompanying drawings.
Example one
The embodiment of the application provides a position positioning method, which is applied to electronic equipment, wherein the electronic equipment comprises N coil antennas, N is a positive integer, in practical application, the N coil antennas can form an antenna array, and the antenna array is arranged behind a touch screen and a display control module.
In a specific implementation process, the length of the coil antenna can be equal to the width or the length of the display screen, the width is not limited by the size of the tag, generally, in order to reduce the number of the coil antennas, the width of the coil antenna is generally larger than 1.5 times of the diameter of the tag, but cannot be too wide, and the phenomenon that the center of the coil antenna cannot be read occurs when the coil antenna is too wide. And the diameter of the overlapped part is generally larger than the 1/4 label diameter and smaller than the 1/2 coil width, so that the condition that an electronic label cannot be detected at the seam of the two coil antennas is avoided. So that the electronic tag can be read by at least one coil antenna at any position on the display screen. In this embodiment of the application, the coil antenna may be an NFC antenna, and the first electronic tag may be an NFC tag.
As shown in fig. 1, the method includes:
s1: and determining the identification position corresponding to the identifiable region of each coil antenna in the N coil antennas on the display unit of the electronic equipment to obtain N identification positions.
In the embodiment of the present application, N may be 5, 8, or 10, which is not limited in the present application.
Specifically, the identification position of each coil antenna can be determined in the following two ways, but in practical applications, the identification position is not limited to the following two ways.
In the first mode, coil antennas in the antenna array are sequentially turned on, and an area that can be recognized when the antennas are turned on is determined as a recognition position of the coil antenna, which is sequentially performed, so as to obtain a recognition position of each coil antenna.
Specifically, the electronic device in this embodiment of the application further includes a plurality of switches, so that each coil antenna in the antenna array is connected to the reader/writer through a switch, and the MCU is also connected to the coil antenna through a switch.
Such as: the antenna array includes 5 coil antennas, and 5 switches are required to be connected to each coil antenna.
The micro control unit controls each switch to be in a connection state or a disconnection state by receiving a switch control command sent by the processor. When a switch is in an off state, the coil antenna connected with the switch is in a non-conducting state, and when a switch is in an on state, the coil antenna connected with the switch is in a conducting state, and at the moment, the coil antenna sends a radio frequency signal to detect nearby electronic tags.
In the second mode, the corresponding position on the display unit right above each coil antenna is used for determining the identification position of the coil antenna.
Next, the identification of the recognition position will be described using a smartphone as an example.
Specifically, assuming that the length of the display screen of the mobile phone is 8cm, the width of the display screen is 4.5cm, and the length of the coil antenna is 8cm, and the width of the coil antenna is 1.5cm, the antenna array includes 4 coil antennas arranged in parallel with the long edge of the display screen, and the width of the overlapping position of two adjacent coil antennas is 0.5 cm.
Assuming that the identification position of each coil antenna is determined in the second manner, taking the vertex of the screen as the origin of coordinates, the short side as the x axis, and the long side as the y axis, from left to right, the identification position of the first coil antenna is a left region where the straight line x on the display screen is 1.5cm, the identification position of the second coil antenna is a region where the straight line x on the display screen is between 1cm and 2.5cm, the identification position of the third coil antenna is a region where the straight line x on the display screen is between 2cm and 3.5cm, and the identification position of the fourth coil antenna is a region where the straight line x on the display screen is between 3cm and x 4.5 cm.
Next, step S2 is introduced: when a first electronic tag is located on the display unit, M coil antennas capable of detecting the first electronic tag are determined from the N coil antennas, wherein M is an integer less than or equal to N.
Specifically, a radio frequency sine wave generated by the reader imparts energy to the tag and data is read from the tag. Taking a mobile phone with a built-in NFC chip as an example, after NFC is started, a sine wave signal with a center frequency of 13.56MHz is continuously generated. If the label is in the magnetic field disturbance range generated by the sine wave, the label obtains energy through the magnetic field disturbance, and the original sine wave counter frequency or the wave with the changed frequency attribute is generated. The handset detects this change to know that there is a tag nearby. And records the corresponding antenna identification and the ID number of the tag. In this embodiment, the antenna identifier may be a serial number of the antenna, such as: the device includes 4 coil antennas, which may be numbered 1, 2, 3, and 4 in sequence.
Following the example in step S2, the determined M coil antennas include two cases because the coil antennas in the antenna array are partially overlapped with each other.
In the first case, there is a coil antenna that is able to detect an electronic tag, such as the tag 1 in figure 2,
in the second case, two coil antennas overlapped with each other can detect the electronic tag, such as: a first coil antenna and a second coil antenna, such as the tag 2 in fig. 2.
Next, step S3 is introduced: obtaining M identification positions of the M coil antennas from the N identification positions.
Using the identification positions of the coil antennas determined in step S1, when the coil antenna determined in step S2 is the first coil antenna, the determined 1 identification position is the left region where the straight line x is 1.5cm on the display screen, or the coil antennas determined in step S2 are the first coil antenna and the second coil antenna, and the determined 2 identification positions are the left region where the straight line x is 1.5cm on the display screen and the region where the straight line x is between 1cm and 2.5 cm.
Then, step S4 is executed: determining a first electronic tag position of the first electronic tag on the display unit based on the M identification positions.
Specifically, in the present embodiment, when a plurality of coil antennas are sequentially turned on from left to right, and only one coil antenna can detect an electronic tag, the identification position corresponding to the portion of the coil antenna that does not overlap with the right coil antenna is determined as the position of the electronic tag, and when two coil antennas can detect an electronic tag, the overlapping area of the identification positions of the two coil antennas is determined as the position of the electronic tag.
For example: the 1 recognition position that determines is the region on the display screen on the left of straight line x ═ 1.5cm, then electronic tags's position is: the straight line x on the display screen is 1.5cm left area. For another example: the determined 2 identification positions are respectively: the left area of the display screen where the straight line x is 1.5cm and the area between the display screen where the straight line x is 1cm and x is 2.5cm, then the position of the electronic tag is: the overlapping area of the two areas is: and the area between the straight line x being 1cm and the straight line x being 1.5cm on the display screen.
In the embodiment of the present application, in order to accurately locate the position of the electronic tag, the antenna array in the present application may adopt the following three layout modes, and in practical application, the antenna array is not limited to the following three modes.
In the first way, the antenna array includes a row of coil antennas, as shown in fig. 2.
Specifically, each coil antenna includes two parts: a first portion overlapping with one adjacent coil antenna, as shown by a in fig. 2, and a second portion excluding the first portion, as shown by b in fig. 2.
In the embodiment of the present application, when the screen size is large, the antenna array is improved to implement an antenna array with a larger size and seamless identification.
Wherein the number and layout of the second column of coil antennas are the same as the first column of coil antennas, and each coil antenna in the second column of antenna coils overlaps with a corresponding antenna portion in the first column of coil antennas, as shown in fig. 3.
Specifically, in the second mode, the detection result can be classified into the following three cases according to the number of coil antennas that detect the electronic tag.
In the first case, one or both of the first column of coil antennas can detect the electronic tag, and none of the second column of coil antennas can detect the electronic tag.
In the second case, one coil antenna in the first row of coil antennas can detect the electronic tag, and one coil antenna in the second row of coil antennas can detect the electronic tag.
In a third case, two coil antennas in the first row of coil antennas can detect the electronic tag, and two coil antennas in the second row of coil antennas can detect the electronic tag.
For the determination of the position of the electronic tag on the screen under the three conditions, the determination may be performed according to the determination method of the first mode, which is not described herein again.
In a third mode, the antenna array includes two rows of coil antennas.
For both the first and second modes, the position of the electronic tag in one direction can only be located, while for the antenna array in the third mode, the positions of the electronic tag in two directions can be located by respectively arranging a column of coil antennas in the two directions. And the layout of the second row of coil antennas is the same as that of the first row of coil antennas. In particular implementations, the width of the coil is typically less than 2 times the width of the tag in order to achieve more precise positioning.
In the embodiment of the present application, the second column of coil antennas may be arranged perpendicular to the first column of coil antennas, as shown in fig. 4. And if the first row of coil antennas are parallel to the first side of the screen, the second row of coil antennas are parallel to the second side of the screen, the vertex of the screen is taken as the origin of coordinates, the first side is an x axis, and the second side is a y axis, so that the coordinate range of the electronic tag on the screen can be determined through the two rows of coil antennas in the x axis direction and the y axis direction.
Specifically, assuming that the length of the display screen of the mobile phone is 7.5cm, the width of the display screen is 4.5cm, the length of the first row of coil antennas is 7cm, the width of the first row of coil antennas is 1.5cm, and the width of the overlapping position of two adjacent coil antennas is 0.5cm, the first row of coil antennas includes 4 coil antennas arranged in parallel with the second side (y axis) of the display screen, the length of the second row of coil antennas is 4.5cm, the width of the second row of coil antennas is 1.5cm, and the width of the overlapping position of two adjacent coil antennas is 0.5cm, and the second row of coil antennas includes 7 coil antennas arranged in parallel with the first side (x axis) of the display screen.
From left to right, the identification position of the first coil antenna is an area on the left side of the straight line x on the display screen, the identification position of the second coil antenna is an area between the straight line x on the display screen and 1cm, x is 2.5cm, the identification position of the third coil antenna is an area between the straight line x on the display screen and 2cm, x is 3.5cm, and the identification position of the fourth coil antenna is an area between the straight line x on the display screen and 3cm, x is 4.5 cm.
From bottom to top, the recognition position of the first coil antenna is an area below a straight line y on the display screen being 1.5cm, the recognition position of the second coil antenna is an area between the straight line y on the display screen being 1cm and y being 2.5cm, the recognition position of the third coil antenna is an area between the straight line y on the display screen being 2cm and y being 3.5cm, and so on.
Specifically, in the third mode, the detection result can be classified into the following three cases according to the number of coil antennas that detect the electronic tag.
In the first case, one coil antenna in the first column of coil antennas can detect the electronic tag, and one coil antenna in the second column of coil antennas can detect the electronic tag.
Assuming that the third coil antenna in the first column and the second coil antenna in the second column can detect the electronic tag, the electronic tag is located in an area where a straight line x is 2cm, x is 3.5cm, y is 1cm, and y is 2.5cm on the display screen, as shown in tag 1 in fig. 4.
In the second case, two coil antennas in the first row of coil antennas can detect the electronic tag, and one coil antenna in the second row of coil antennas can detect the electronic tag.
Assuming that the third coil antenna in the first column, the fourth coil antenna and the second coil antenna in the second column can detect the electronic tag, the electronic tag is located in an area formed by a straight line x being 3cm, x being 3.5cm, y being 1cm and y being 2.5cm on the display screen, as shown in fig. 4, i.e., tag 2.
In a third case, two coil antennas in the first row of coil antennas can detect the electronic tag, and two coil antennas in the second row of coil antennas can detect the electronic tag.
Assuming that the third coil antenna, the fourth coil antenna in the first column and the second coil antenna and the third coil antenna in the second column can detect the electronic tag, the electronic tag is located in an area formed by a straight line x being 3cm, x being 3.5cm, y being 2cm and y being 2.5cm on the display screen, as shown in a tag 3 in fig. 4.
In the embodiment of the application, the device can read information written in the electronic tag while determining the position of the electronic tag on the screen, and further execute the function in the tag. And other innovative functions are realized through the identification and the positioning of the electronic tag.
Next, taking an example that the smartphone recognizes the NFC tag on the positioning screen to implement a corresponding function thereof, an innovative function in the embodiment of the present application will be described.
For example: a plurality of coupons are displayed on a screen of a current smart phone, each coupon needs to be downloaded to the local first when in use, at the moment, a user places an NFC label with a function of writing in and downloading the coupon on the screen, and the coupon corresponding to the placement position of the NFC label is located through the electronic label positioning method in the embodiment of the application, so that the selection and downloading of the coupon can be realized.
In the embodiment of the application, the positioning of the plurality of electronic tags on the display screen can be realized by recording the identification of the coil antenna of the detected electronic tag and the ID number of the electronic tag.
Assuming that the identification of the antenna is the serial number of the antenna, the reader-writer can read the ID number of the tag and the serial number of the antenna, and then the electronic equipment determines the position of the tag with the ID number according to the antenna reading the same ID number and the identification position of the antenna.
