What is an electronic shelf? What is his operation process?
Electronic shelves consist of electronic display screens and shelf labels.
With the rapid development of the retail industry, display shelves more and more varieties of goods, supermarket promotional activities also makes commodity price more and more frequent, which leads to a supermarket to spend a lot of energy and replacement in the management of the price tag, and the error is inevitable due to the inconsistent shelf price tag and POS the price system, and ultimately lead to customer complaints, damaged the credibility of the meet the eye everywhere. It is these reasons that spawned the birth of ESL.
The so-called electronic shelf label (ESL), is a fixed on the shelf, display the commodity prices through the LCD screen, used to replace the paper label equipment, ESL through wireless technology to connect with the supermarket server, when the commodity price changes, the price will automatically update the display synchronization.
The ESL system mainly consists of three steps, firstly the background of the management procedures, and responsible for the supermarket server connection, access price of commodity information, and transmitted to the wireless base station; in fact wireless communication through the wireless base station will be issued under the price information for each ESL; finally, ESL accepted the new price will display the price update. One of the core technologies is wireless communication.
At present, the more common ESL wireless communication technology has 4 kinds: infrared ray, 38.4KHz, low frequency radio, visible light transmission, 2.4GHz high frequency radio. Of which the first 2 kinds of technology because of entering the earliest, use the most, but due to the short communication distance is gradually being replaced; third is easy to be disturbed; fourth kinds of 2.4GHz communication technology while entering the late, but because of long communication distance and reliable communication quality, is gradually by the customer accept.
