A low-power intelligent electronic price system and its implementation method

Abstract

The invention discloses a low-power-consumption intelligent electronic price system and a realization method thereof. The low-power-consumption intelligent electronic price system is characterized in that an area controller comprises a first wireless transceiver unit, a second wireless transceiver unit and a third wireless transceiver unit, wherein the second wireless transceiver unit adopts an ACK (Acknowledge Character)-free receiving mode and works in a second frequency range; the third wireless transceiver unit adopts an ACK-free transmitting mode, works in a second frequency range and is responsible for communicating with an electronic price tag to solve the problem of data packet dropout caused by data collision generated when multiple tags simultaneously communicate with the area controller; and the first wireless transceiver unit adopts an automatic ACK work mode, works in a first frequency range and is responsible for receiving current display information of the electronic price tag and carrying out uplink and downlink data interaction with a gateway. The work frequency range of the first wireless transceiver unit is different from the work frequency ranges of the second wireless transceiver unit and the third wireless transceiver unit, so that when a frequency-hopping technology is adopted during work, frequency interference during tag data update can be avoided and further data packet dropout in the process of data transmission can be effectively avoided.

Description

technical field [0001] The invention relates to an electronic price system, in particular to a low power consumption intelligent electronic price system and its realization method. Background technique [0002] The smart electronic price system, also known as the Electronic Shelf Label System (ESLs for short), is an electronic display device placed on the shelf that can replace traditional paper price tags. The benefits it brings to retailers are very obvious. According to statistics, a typical retail store has about 10,000-12,000 price changes per week. Manually replacing paper labels will bring a lot of expenses, and often these operations are inefficient and unreliable, and require a lot of time. At the same time, the correctness of all label prices cannot be guaranteed, which is a huge obstacle to improving management efficiency and reducing operating costs. The intelligent electronic price system is developed to solve these problems, using the currently widely used net...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing intelligent electronic price system usually includes a data management center, a regional controller, a terminal electronic price tag, a handheld device and a POS terminal. The regional controller adopts a single antenna or a dual antenna. In this type of system, when multiple tags communicate with the regional controller at the same time, there will be a data collision problem, resulting in data packet loss, resulting in the system not being able to update data in a timely and accurate manner.
