Electronic price tag reservation brushing method and device, and computer storage medium

Abstract

The invention discloses an electronic price tag reservation brushing method and device, and a computer storage medium, and the method comprises the steps: obtaining a display time parameter through receiving a push picture which is transmitted by a server and carries the display time parameter, and returning response information to the server; judging whether the display mode of the pushed picture is appointment display or real-time display according to the display time parameter; sending the identification information carrying the display mode and the push picture to a corresponding electronic price tag according to the judged display mode, so that the electronic price tag stores the push picture according to the identification information; meanwhile, when the display mode is appointment display, enabling the base station to start an appointment brushing timer; and when the timer reaches the time corresponding to the display time parameter, enabling the base station to send prompt information to a corresponding electronic price tag based on a broadcast gateway, prompting the electronic price tag to update and displaying the push picture. The time accuracy of booking picture refreshing is improved, and the time error of booking picture refreshing is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, and in particular, to a method, device and computer storage medium for an electronic price tag reservation brushing. Background technique [0002] The speed and efficiency of the electronic price tag system are the most critical indicators that affect its evaluation. In large supermarkets, there are many products. Correspondingly, the number of electronic price tags is also very large. It is almost impossible to change prices together in a short time. things, especially when price information is transmitted through pictures. For example, the size of a 4.2-inch image is 30K, and it is transmitted by 2.4G air interface, and the protocol overhead is removed, and it takes about 2 to 3 seconds to complete the transmission; if there are 1000 electronic price tags under a base station, then all electronic price tags are transmitted. The picture takes 2*1000 seconds or about 33 minutes. In some sce...

Problems solved by technology

But this solution has a disadvantage, that is, the crystal oscillator itself has a certain error, and as time goes on, its error will become larger and larger, and the electronic price tag is a low-power product, and it is in a dormant state most of the time. It will also greatly affect the timing accuracy of the crystal oscillator clock inside the electronic price tag
