The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The inventor finds technical problems mentioned in the background technology, and provides a multi-antenna electronic price tag scheme aiming at the business and super environments, and the scheme realizes that different antennas are adopted to achieve system optimization when different functional requirements are met. The scheme of the multi-antenna electronic price tag is described in detail below.
Fig. 1 is a schematic structural diagram of an electronic price tag according to an embodiment of the present invention, and as shown in fig. 1, the electronic price tag includes: the antenna comprises a main control chip and a plurality of antennas; wherein:
the main control chip 1 is used for selecting an antenna communicated with the main control chip from the plurality of antennas 2 according to a function demand command; controlling an antenna communicated with the main control chip to receive or send different price tag signals, and enabling the electronic price tag to meet different functional requirements according to the price tag signals sent by the antenna communicated with the main control chip;
each antenna is used for receiving or sending different price tag signals under the control of the main control chip when being communicated with the main control chip, and sending the received price tag signals to the main control chip.
The inventors have found a technical problem: usually, the main control chip inside the electronic price tag is responsible for communicating with the AP to transmit information to be displayed, and controlling the display screen to display. Because big merchants have business requirements of finding goods in real time, guiding shopping and the like, how to quickly and accurately position commodities in the merchants is a problem which needs to be solved urgently. The traditional indoor positioning methods include ibeacon and uwb, wifi fingerprint and the like. The positioning accuracy of the schemes is more than 1m, even the error reaches 10m, and the requirement of dense commodity display positioning cannot be met. The wireless communication system where the electronic price tag is located is utilized for positioning, and the main function of the built-in antenna of the electronic price tag is to communicate with the AP, so that the functional requirement that neighbors need to be detected with weak functions in the positioning process cannot be met, the electronic price tag cannot be positioned quickly and accurately, and the optimal system cannot be achieved.
The inventor considers the technical problem and provides a scheme that the electronic price tag can be positioned quickly and accurately and the optimal system can be achieved, namely when the electronic price tag provided by the embodiment of the invention works, the main control chip selects which antenna to use according to the function required to be completed by the price tag. Functions other than the communication function are realized quickly and accurately. The electronic price tag includes: main control chip and a plurality of antenna, through: the main control chip selects an antenna communicated with the main control chip from the plurality of antennas according to the function demand command; controlling an antenna communicated with the main control chip to receive or send different price tag signals, and enabling the electronic price tag to meet different functional requirements according to the price tag signals sent by the antenna communicated with the main control chip; when each antenna is communicated with the main control chip, different price tag signals are received or sent through the control of the main control chip, and the received price tag signals are sent to the main control chip, so that the system optimization is achieved by adopting different antennas according to different function requirements of the electronic price tags.
The technical scheme provided by the embodiment of the invention can be applied to electronic price tags, APs (access points) comprising the electronic price tags and the like.
How the embodiment of the invention is implemented is described below in terms of the electronic price tag which can realize the function of communication display price tag information and the positioning function.
During specific implementation, the plurality of antennas can be antennas in the electronic price tag shell, are generally onboard antennas, and can also be connected with a circuit board where the main control chip is located through special antenna connectors or contacts and are assembled and fixed through special accessories. The multiple antennas can be selected by electronic switch control, or can be directly connected together to form an antenna array by the space position between them, and the antenna array has specific directivity. Several embodiments of ways of controlling the selection of the antennas are described below.
In one embodiment, as shown in fig. 2, the antennas may include a first antenna 21 and a second antenna 22;
the main control chip 1 may specifically be configured to:
when the function demand command is a display command, selecting an antenna connected with the main control chip, for example, a first antenna 21, from the plurality of antennas; controlling a first antenna 21 communicated with a main control chip to receive or send different price tag signals, such as a signal of a commodity represented by an electronic price tag, and enabling the electronic price tag to complete the display function requirement according to the price tag signals (such as information of the commodity represented by the electronic price tag) sent by the antenna communicated with the main control chip;
when the function demand command is a positioning command, selecting an antenna connected with the main control chip from the plurality of antennas, for example, the second antenna 22, controlling the antenna connected with the main control chip to receive or send different price tag signals, that is, controlling the second antenna 22 to be in a sending mode state, or controlling the second antenna 22 to be in a receiving mode state, and determining the position information of the electronic price tag in the receiving mode according to the price tag signal sent by the antenna connected with the main control chip, that is, according to the identity information of the electronic price tag in the receiving mode and the identity information of the adjacent electronic price tag, so that the electronic price tag can complete the function demand of positioning;
the first antenna may be specifically configured to:
when the antenna is communicated with the main control chip, the antenna is communicated with the wireless access point through the control of the main control chip, the information of the commodity represented by the electronic price tag is received, the information of the commodity represented by the electronic price tag is sent to the main control chip, and at the moment, the first antenna is in a normal communication state;
the second antenna may be for: when the electronic price tag is communicated with the main control chip, different price tag signals are received or sent under the control of the main control chip, for example, when the electronic price tag is in a sending mode state under the control of the main control chip, the identity information of the electronic price tag is sent; when the electronic price tag is communicated with the main control chip, the identity information (price tag signal) of the adjacent electronic price tag is received under the control of the main control chip, namely, when the electronic price tag is in a receiving mode state under the control of the main control chip, and the identity information of the adjacent electronic price tag and the identity information of the electronic price tag are sent to the main control chip.
In the specific implementation, under normal conditions, the main control chip communicates with the AP through the first antenna 21 (built-in antenna), and completes information transmission. When the price tag position needs to be located through the price tag system, the system (which can be an electronic price tag system or a server) controls the price tag to enter a state of searching for a neighbor through a command (a locating command), namely, identity information of an adjacent electronic price tag is received. After receiving this command, the electronic price tag controls the switch to the second antenna 22 (external antenna) according to a predetermined protocol within a synchronized time window, transmits its own identity information on this external antenna according to a predetermined power, and receives the identity information of other surrounding price tags (neighboring electronic price tags), thereby determining its surrounding neighbor information (identity information of neighboring electronic price tags).
To facilitate understanding of how the present invention is implemented, an example is illustrated of how the electronic price tag performs the location function.
For example, there are 6 electronic price tags. Wherein, one No. 1 electronic price tag is in a receiving mode, the second antenna of the No. 1 electronic price tag is controlled to receive the identity information sent by the other 5 adjacent electronic price tags, and the identity information sent by the other 5 adjacent electronic price tags is sent to the main control chip, and the main control chip determines the position information of the No. 1 electronic price tag in the receiving mode according to the received identity information of the adjacent electronic price tags and the identity information of the electronic price tag, so that the No. 1 electronic price tag can meet the functional requirement of price tag positioning. When another 5 electronic price tags need to be located, for example, the number 2 electronic price tag needs to be located, then, the number 1 electronic price tag needs to send its own identity information to the number 2 electronic price tag, and the location method of the number 2 electronic price tag refers to the location method of the number 1 electronic price tag.
According to the electronic price tag in the receiving mode, in the positioning process, the second antenna of the electronic price tag is controlled by the main control chip to realize that the identity information of the adjacent electronic price tag needs to be detected with weak functions, and the electronic price tag in the receiving mode is quickly and accurately positioned according to the identity information of the adjacent electronic price tag, so that the system optimization is achieved. During specific implementation, the second antenna of the electronic price tag can also send the received identity information of the adjacent electronic price tag and the identity information of the electronic price tag to a server, and the server determines the position information of the electronic price tag in a receiving mode state according to the received identity information of the adjacent electronic price tag and the identity information of the electronic price tag.
In one embodiment, the electronic price tag may further include: the first switch 3 is connected with the main control chip and the plurality of antennas;
the main control chip is specifically configured to: according to the function requirement command, an antenna communicated with the main control chip is selected from the multiple antennas by controlling the first switch, the antenna communicated with the main control chip is controlled to receive or send different price tag signals, and according to the price tag signals sent by the antenna communicated with the main control chip, the electronic price tag can meet different function requirements.
In specific implementation, as shown in fig. 2, a first switch 3 can be used to be connected or disconnected with any antenna of the multiple antennas under the control of the main control chip, so as to control any antenna of the multiple antennas to be in different working states, so that the electronic price tag can meet different functional requirements, and is convenient and flexible.
In an embodiment, as shown in fig. 3, the main control chip is specifically configured to: selecting an antenna communicated with the main control chip from the plurality of antennas based on the spatial angle position information of the plurality of antennas according to the function demand command; and controlling the antenna communicated with the main control chip to receive or send different price tag signals, and enabling the electronic price tag to meet different functional requirements according to the price tag signals sent by the antenna communicated with the main control chip.
In a specific implementation, for example, when the antennas include the third antenna 23 and the fourth antenna 24, a preset angle (spatial angle position information) exists between the third antenna and the fourth antenna.
In a specific implementation, as shown in fig. 3, the third antenna 23 and the fourth antenna 24 are spatially separated by a distance D, D may be a half wavelength (e.g., 6cm, or 18cm, etc.) of an electronic price tag communication frequency (e.g., 2.4G, or 900M, etc.), or a wavelength of 1/4, etc., so as to form the directionality of the signal in space, and achieve the purpose of distinguishing electronic price tag signals within and outside a corresponding angle.
In one embodiment, as shown in fig. 4, the electronic price tag may further include: the second switch 4 is connected with the main control chip and the plurality of antennas;
the main control chip is specifically configured to: selecting an antenna which is communicated with the main control chip from the plurality of antennas according to a preset time sequence by controlling the second switch based on the spatial angle position information of the plurality of antennas according to a function demand command; and controlling the antenna communicated with the main control chip to receive or send different price tag signals, and enabling the electronic price tag to meet different functional requirements according to the price tag signals sent by the antenna communicated with the main control chip.
In a specific implementation, the distance D between the third antenna and the fourth antenna in space may be a half wavelength (e.g., 6cm, 18cm, etc.) of an electronic price tag communication frequency (e.g., 2.4G, 900M, etc.), or a wavelength 1/4, etc., and the main control chip controls the switch to select different antenna receiving signals according to a certain specific time sequence, and performs operations on the signals from the two different antennas, so as to achieve the purpose of distinguishing electronic price tag signals within and outside a corresponding spatial angle.
According to the method, the price tag can realize accurate measurement of the neighbor price tag through the special design of the external antenna, such as larger attenuation and better directivity, and the rapid and accurate electronic price tag positioning function is realized.
The above embodiment is described only by using the electronic price tag to implement the function of displaying the price tag information through communication and the function of positioning, but a person skilled in the art can also imagine implementing other functions, for example, detecting the indoor environmental parameter information through a fifth antenna, such as the smoke concentration, the formaldehyde index, etc., so that the electronic price tag implements the function of real-time alarm through safety detection.

Because the principle of solving the problem of the working method of the electronic price tag is similar to that of the electronic price tag, the implementation of the working method of the electronic price tag can refer to the implementation of the electronic price tag, and repeated parts are not repeated. As used hereinafter, the term "module" or "unit" may be a combination of software and/or hardware that implements a predetermined function.
