s1, when the electronic price tag is electrified, full-frequency point scanning is carried out, and the base station with the highest signal intensity is used as the subordinate base station of the electronic price tag;
s2, receiving a mapping broadcast packet sent by the subordinate base station, wherein the mapping broadcast packet comprises a price tag ID, state information and frequency point information;
s3, if the price tag ID is determined to include the ID of the electronic price tag, initiating connection to the subordinate base station according to the state information and the frequency point information;
and S4, when the mobile terminal is accessed to the idle gateway of the subordinate base station, obtaining the picture data of the picture by the idle gateway.
In this embodiment, first, when the electronic price tag is powered on, full-frequency point scanning is performed, and a base station with the highest signal strength is used as a subordinate base station of the electronic price tag; then, receiving a mapping broadcast packet sent by the subordinate base station, wherein the mapping broadcast packet comprises a price tag ID, state information and frequency point information; then, if the price tag ID is determined to comprise the ID of the electronic price tag, connection is initiated to the subordinate base station according to the state information and the frequency point information; and finally, after accessing to the idle gateway of the subordinate base station, acquiring the picture data of the picture brushing through the idle gateway.
Specifically, in this embodiment, taking the base station with four gateways as an example, the four gateways respectively work at four different frequency points, and select any one of the gateways as a broadcast gateway, and the other three gateways as data gateways, the broadcast gateway continuously broadcasts a data packet to the outside, where the broadcast packet includes information of the frequency points of the other three gateways, status information, and price tag ID of the called electronic price tag. In this embodiment, since the broadcast gateway is continuously broadcasting, the electronic price tag wakes up from a sleep state at any time point to acquire the state information of the base station gateway, and at this time, the electronic price tag can adopt periodic sleep to ensure that the power consumption reaches the standard, and acquires the state and frequency point information of other three data gateways from the broadcast packet each time it wakes up, and if the base station finds that there is a call in the broadcast packet, it selects any idle data gateway to initiate a connection request, and executes a subsequently defined task after the connection is successful.
In this embodiment, optionally, only one frequency point data may be monitored by the electronic price tag, but different electronic price tags may complete services on different data gateways, so that the gateways operate in parallel, which improves the operating speed, and meanwhile, since only one frequency point is monitored and the sleep time can be freely controlled according to the power consumption requirement, the operating power consumption of the electronic price tag may also be guaranteed.
In the embodiment, because each gateway works in parallel, each electronic price tag end can determine the sleep time according to the power consumption requirement of the gateway, does not need to keep time synchronization with other price tags, is easy to realize and has controllable power consumption; meanwhile, a plurality of data gateways can simultaneously brush pictures to different price tags in parallel, the speed is high during batch picture brushing, and the requirements of improving the working speed during parallel work can be met while the power consumption design is met.
The embodiment has the advantages that the base station with the highest signal intensity is used as the subordinate base station of the electronic price tag by scanning the full-frequency point when the electronic price tag is electrified; then, receiving a mapping broadcast packet sent by the subordinate base station, wherein the mapping broadcast packet comprises a price tag ID, state information and frequency point information; then, if the price tag ID is determined to comprise the ID of the electronic price tag, connection is initiated to the subordinate base station according to the state information and the frequency point information; and finally, after accessing to the idle gateway of the subordinate base station, acquiring the picture data of the picture brushing through the idle gateway. The humanized scheme for concurrently swiping the electronic price tags is realized, the swiping efficiency is improved, the power consumption requirement is reduced, and the user experience is enhanced.
