Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] see Figure 1 to Figure 4 As shown, an electronic price tag system based on the POWERBUS bus of the present invention includes a host computer 10, at least one electronic price tag host 20 connected to the host computer 10, and an electronic price tag slave 30; each electronic price tag host 20 passes through Two non-polarity POWERBUS buses are connected to multiple electronic price tag slaves 30 to provide DC power and perform real-time signal transmission. The POWERBUS bus is a power supply cable. The wiring method of the POWERBUS bus is flexible and can adapt to various wires and wiring methods on site. It can support any laying method such as bus type, tree type or star type, which greatly facilitates construction and wiring.

The invention discloses an electronic price tag system based on a POWERBUS bus. The electronic price tag system comprises an upper computer, at least one electronic price tag host connected with the upper computer, and an electronic price tag slave, Each electronic price tag host is connected with a plurality of electronic price tag slaves through two non-polar POWERBUS buses so as to provide a direct current power supply and perform real-time signal transmission; And the POWERBUS bus is a power supply cable. Compared with a traditional paper price tag, a large amount of manpower and materialresources are saved, manual handwriting errors are eradicated, and meanwhile data can be synchronized with an upper computer and a bar code scale in real time to avoid misunderstanding of customers; Compared with various existing wireless electronic ink screens, wireless LCD screens and other wired screens, the wireless electronic ink screen has the advantages of being low in cost, convenient to construct, easy to maintain, reliable in signal transmission and the like.
Description
technical field [0001] The invention relates to the technical field of electronic price tags, in particular to an electronic price tag system based on a POWERBUS bus. Background technique [0002] In traditional supermarket paper price tags, it takes an average of two minutes to change a price tag, and the overall labor is heavy; and according to statistics from relevant organizations, the average price tag loss rate in this process is 2%, and the manual error rate is 6%. Not only did it consume a lot of manpower and material resources, but the used price tags also caused a considerable degree of waste. In addition, in the case of using paper price tags, the low efficiency of manual price changes leads to inconsistent prices between commodity price tags and the cash register system, causing many misunderstandings by customers. Furthermore, the costs of paper, ink, and printing involved in paper price tags are also increasing day by day. Therefore, in order to find new sale...
