Abstract

The invention relates to technical field of electron, and discloses a method and device of node update. The method of the node update comprises the steps of dividing the step of refresh a display screen into N sub-steps in advance, wherein N is a natural number bigger than 1; receiving update data; when the update data is completely received, and utilizing the update data to refresh the display screen, wherein when display screen refreshing is executed, a sleeping state is entered between at least two sub-steps. According to the method and device of the node update, the big current duration of a node is reduced, and continuous loss of battery capacity is lowered, so that battery types of a button cell and the like has enough recovery time so as to prolong the service life of a battrery.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a node updating method and device thereof. Background technique [0002] At present, supermarkets, convenience stores, pharmacies, etc. mostly use paper price tags to display product information. The display information of traditional paper price tags cannot be changed flexibly. The information on the paper price tags must be replaced during discounts, product changes, and promotions. The production and maintenance costs are high, and the efficiency of manual price changes is low, and it is easy to lose and misplace. location, resulting in inconsistencies in prices between product price tags and the cash register system, causing unnecessary misunderstandings between merchants and customers. Therefore, in order to find new sales growth points, the use of electronic price tags has become an inevitable trend. Electronic price tags can quickly and accurately process changes in ...
