First embodiment
Fig. 3 is a basic flowchart of an antenna tuning method for an electronic price tag according to this embodiment, where the antenna tuning method for an electronic price tag includes:
s301, acquiring the working state and the working frequency of the electronic price tag.
Electronic price tags, also called Electronic Shelf Labels (ESL), are Electronic display devices with information transceiving functions, and are placed on a Shelf to replace Electronic display devices of traditional paper price tags. Wherein, the operating condition of electron price tag includes: one of a registration state, a standby state and a graph transmission state. It will be appreciated that the requirements for the antenna are different in the case of different operating states of the electronic price tag. Therefore, the operating state and operating frequency of the electronic price tag are obtained in this embodiment for antenna tuning.
In specific implementation, the base station and the electronic price tag are interacted by adopting a 2.4G wireless communication protocol. The base station is continuously powered by a power supply and comprises gateways and a main processor, and the number of the gateways can be flexibly configured according to own protocol systems. The main processor in the base station has data concurrent processing capability, and the base station and the communication module of the electronic price tag communicate with each other by adopting a 2.4G wireless communication protocol, wherein the communication module can be a Radio Frequency communication module (RF communication module). The 2.4GHz technology is adopted and mainly comes from the mature 2.4G technology, and the international planning has a standard communication frequency band (2.4GHzISM), and based on the radio frequency characteristics of 2.4G, the miniaturization design (the antenna can be designed to be very small) is easy to realize, and meanwhile, the communication capacity without dead angles and omni-directional coverage (the antenna can realize omni-directional communication) is easy to realize, so that the electronic price tag is convenient to install, and the implementation and maintenance cost is low. And the uplink and downlink of the 2.4GHz technology have almost the same capability, and the uplink has burst capability.
S302, determining a target tuning matching parameter of the electronic price tag according to the working state and the working frequency of the electronic price tag.
In this embodiment, the target tuning matching parameters of the electronic price tag are finally determined according to the working state and the working frequency of the electronic price tag by acquiring the working state and the working frequency of the electronic price tag.
Specifically, research and development personnel need to debug the optimal tuning matching values of different channels and different working states in a laboratory environment and put the tuning matching values into a storage module, namely, the corresponding relation among the preset working state, the preset working frequency and the tuning matching parameters is set.
In the embodiment of the present invention, the terminal may obtain the corresponding relationship between the preset operating state, the preset operating frequency, and the tuning matching parameter in the following two ways. In one mode, the terminal obtains a corresponding relationship among a preset working state, a preset working frequency and a tuning matching parameter, which are locally pre-stored. For example, the terminal may store in advance a correspondence between a preset operating state, a preset operating frequency, and a tuning matching parameter, which are obtained through experimental measurement, in the local memory, and when the terminal is used, obtain the correspondence from the local. Therefore, the terminal can quickly determine the target tuning matching parameters according to the acquired corresponding relation. In another mode, the terminal receives a correspondence between a preset operating state, a preset operating frequency, and a tuning matching parameter sent by a network device (e.g., RAN). That is, the terminal can obtain not only the correspondence stored locally but also the correspondence existing in other network devices, and in practical application, a suitable implementation manner can be selected according to specific situations. For example, if the local storage space of the terminal is short, the corresponding relationship may be stored in other network devices, and when the terminal needs to use the corresponding relationship, the corresponding relationship may be acquired from other network devices, where the corresponding relationship stored in the network devices may also be obtained through experimental measurement.
And the central processing unit searches a target tuning matching parameter corresponding to the working state and the working frequency according to the corresponding relation of the preset working state, the preset working frequency and the tuning matching parameter.
It should be understood that the electronic price tag system is easily interfered by external wireless communication WIFI, bluetooth and the like, and the data volume of the map transmission is larger, so the requirement on the channel is higher, therefore, in the embodiment of the present invention, tuning is preferably used fully in the state of the map transmission to improve the efficiency of the antenna, and other states can be selected as required. For example, in the registration state, the price tag searches the broadcast channel number of the base station under different channels, and tuning parameters can be called according to the channels when searching the network.
Therefore, in the embodiment of the present invention, when the operating state is the map transmission state, the antenna signal strength after the antenna tuning is the first antenna signal strength; when the working state is the registration state or the standby state, the antenna signal intensity after antenna tuning is the second antenna signal intensity; the first antenna signal strength is higher than the second antenna signal strength. In other words, in the embodiment of the invention, after the antenna tuning is performed in the image transmission state, the transmitting and receiving sensitivity of the electronic price tag is further improved, the image transmission efficiency and success rate are improved, and further, the performance of the electronic price tag is improved.
And S303, carrying out antenna tuning according to the target tuning matching parameters.
And after determining the target tuning matching parameters of the electronic price tag according to the working state and the working frequency of the electronic price tag, performing antenna tuning according to the target tuning matching parameters.
In the embodiment of the present invention, the antenna tuning is performed according to the target tuning matching parameter, and a parameter of a tuning device in the antenna may be adjusted to the target tuning matching parameter. Wherein the tuning device comprises at least one of a tuning switch and a tunable capacitance. In an embodiment of the present invention, the terminal may be provided with at least one antenna, and the tunable capacitor of the at least one antenna includes a plurality of tuning capacitors. Specifically, the adjusting the parameter of the tuning device in the antenna to the target tuning matching parameter includes: and tuning the tunable capacitor and the tuning switch by changing the connection relationship between the tunable capacitor and the tuning switch.
