Description
Technical Field
The invention relates to the technical field of electronic tags, in particular to an electronic tag system and a control method thereof.
Background
Under ever changing market conditions, the retail industry in China has undergone the process of rationalizing and adjusting the operation structure in recent years, and is changed from a large number of small and medium-sized retailers to a limited number of major retail enterprise-controlled large-scale retail enterprise-oriented markets with extremely strong competitiveness. On one hand, the larger the supermarket scale is, the more and more the supermarket commodity types are. On the other hand, in order to adapt to severe competition, the sales strategy of merchants is more flexible, various sales promotion activities are frequent, the price of the commodities changes more and more frequently, so that the merchants spend a great deal of time and energy in replacing and managing price labels, and the traditional paper labels cannot adapt to the requirements of modern supermarkets due to the inherent characteristics of large workload, high error rate, poor real-time performance, environmental pollution and the like.
The electronic shelf label is an intelligent electronic label which can finish storage and automatic identification of goods based on Radio Frequency Identification (RFID) technology. The electronic display device is placed on a commodity shelf to replace a traditional electronic display device of a paper commodity label, is connected with a server of a market through a wireless network, and is used for adjusting the price of the commodity by a worker through application software on a computer of the market and finally displayed on a liquid crystal display screen on the electronic label. The communication technology adopted by the electronic shelf label is generally divided into a wired mode and a wireless mode, and the wired mode mainly has the defects of difficult wiring, poor mobility, high operation and maintenance cost and the like, and the application is less. The wireless mode mainly comprises short-distance wireless communication technologies such as an infrared technology, a ZigBee technology, a Bluetooth technology, a low-frequency radio technology, a 2.4G radio frequency technology and the like.
The electronic shelf label system has larger market space, is beneficial to promoting the development of the electronic shelf label system in China and has good economic efficiency. According to the published authoritative data, the actual market demand of the global market on the electronic shelf labels reaches more than 20 hundred million, and the market value scale reaches about 1000 hundred million. Therefore, the electronic shelf label system meeting the market demand can bring certain promotion effect to economic growth, and the global market of the labels of the electronic shelves has very large development space.
The research and development of the electronic shelf label system is relatively late in China, but the electronic shelf label system has been successfully researched abroad. The first electronic shelf label developed by the company Pricer in Sweden in 1993 and used on a large scale in the home in France in 1999, about 2500 million supermarkets nearly 3 hundred million electronic labels are put into practical use so far globally and are mainly distributed in Oume, Australia, Turkey in the middle east, Japan in Asia, Korea and the like according to statistical data, introduced retailers are Maidlong, 7-ELEVAN and the like, and main suppliers include ZBD company in UK, Altierre company in the USA, FUJITSU company in Japan, SES company in France.
The communication technology adopted by the electronic shelf label is generally divided into a wired mode and a wireless mode, and the wired mode mainly has the defects of difficult wiring, poor mobility, high operation and maintenance cost and the like, and the application is less. The wireless mode mainly comprises short-distance wireless communication technologies such as an infrared technology, a ZigBee technology, a Bluetooth technology, a low-frequency radio technology, a 2.4G radio frequency technology and the like. With the development of wireless communication technology, especially the rapid development of low power consumption wireless local area network technology, many technical-like application products, such as store shelf labels, large-sized storage goods labels, etc., are produced.
However, the existing electronic shelf label system is developed based on a protocol of a certain processor, and the development protocol is usually not open due to self protection of manufacturers, which causes the after-sale problems of incompatibility of various electronic labels, difficulty in maintenance, high replacement cost and the like. In addition, when the existing electronic shelf label system updates the commodity information displayed by the electronic shelf label each time, the existing electronic shelf label system needs to go to the background server for updating, then goes to the shelf to check whether the updating is accurate or not, the maintenance and management manpower investment is large, and the user experience degree is low.
Moreover, the existing electronic shelf label only has the function of price display, and cannot realize the function of voice broadcast, so that the old and middle-aged people with poor eyesight can hardly check the price of the goods on the electronic label, and the old glasses are required to be equipped. In addition, some goods are placed on the bottom layer of the goods shelf, the middle-aged and the old cannot easily see the waist and the legs, and the middle-aged and the old need to bend down to see the price on the electronic tag at the time, so that the middle-aged and the old are very troubled, and the shopping experience is greatly discounted.
In addition, the placing position of the goods in the existing sales places directly affects the attention degree of the customers, but even if the goods are placed in a very good position in the sales places, the goods are not always sold, and the goods can be sold. Therefore, the selling condition of the product is researched, the selling condition of the product is improved by a merchant, the placing strategy of the product is researched, but in the prior art, the selling condition of the product can be analyzed only through data fed back by a cashier desk, the data source is single, the analysis is not accurate, and the reference value of the product for improving the merchant is not high. The prior art lacks an electronic tag capable of feeding back preference data of a customer commodity in real time.
In addition, the current stores need the manual work to make a round trip to patrol and mend the goods, and the human input is big, lacks an electronic tags that can realize automatic benefit and remind function among the prior art.
