Description
Technical Field
The invention mainly relates to the technical field of computers, in particular to an electronic price tag system and a communication method thereof.
Background
An Electronic price Label (ESL) is an Electronic display device with an information receiving and sending function, can be placed on a Shelf to replace a traditional paper price Label, can greatly save labor cost, and can be widely applied to various commercial environments such as supermarkets, convenience stores, warehouses and the like.
At present, the scheme of the electronic price tag system in the industry is that a plurality of base stations (Access points, APs) are installed and deployed in a merchant, the base stations are connected with a computer database of a shopping mall in a wired or wireless network mode, and each electronic price tag is connected and communicated with the base station adjacent to the electronic price tag in a wireless network mode. Thus, the modification of the product information by the merchant can be transmitted to each electronic price tag associated with the merchant through the base station. For example, data communication is performed between the price tag and the base station through low power consumption bluetooth technology (BLE), and the base station, as a connected person (Slave or Peripheral) of BLE communication, transmits current information in a bluetooth broadcast mode at certain broadcast intervals in a 2.4GHz frequency band. And the price tag is used as an initiator (Master or Central) of BLE communication, and the broadcast content in the air is scanned by the price tag at a fixed scanning period. If the broadcast content is related to the price tag, the price tag will try to connect with the base station, after the connection is successful, the base station will transfer the corresponding service information to the price tag, and the price tag will execute the corresponding service operation according to the indication, such as price change.
The current widely used electronic price tag system solution has an obvious defect that at least one base station needs to be installed and configured, and corresponding operation can be executed only after the price tag correctly receives a signal sent by the base station. The cost of the base station is generally higher, and the single sale price is about 1000 to 3000, which is hard to accept for small and medium sized shops with less price tag. For small shops, the business area of the base station is not large, some shops even lease in a short period of time, and the cost performance of installing and constructing the base station is low due to extra manpower cost. In addition, for small shops, if price tags at some corners are poor in received signals due to environmental factors (such as bearing walls or shielding), the price tags have to be solved by adding base stations, and accordingly the purchasing cost of customers is increased.

The light emitting module 114 is used for positioning and prompting display of the electronic price tag, and the controller 111 controls the light emitting module 114 to turn on, flash or turn off the light according to corresponding operation instructions. The display screen 115 is used for displaying specific commodity information of the electronic price tag, and when the operation data packet includes an operation instruction for refreshing the commodity information, the controller 111 refreshes the commodity information included in the bluetooth data packet to the display screen 115.
Step 209: when the operation is finished, the working mode is switched into a low power consumption mode;
