Abstract

The utility model provides an electronic shelf label based on MSP430 comprises electron drive module, wireless communication module, display module and power module, is connected through wireless communication module and intermediate equipment, when the price of certain product changes in the system of supermarket, sends the order to the electron price tag that corresponds through intermediate equipment, through the both -way communication real -time trail to appraise at the current rate issue to accessible time feed back the success information of appraising at the current rate. Every wireless electronics goods shelves label all has a sole ID number, can effectively avoid taking place the condition that wrong data were received to the electron price tag. The beneficial effects are that, can show the content through wireless mode real -time update module, timely new thing feedback to terminal more, the operator of being convenient for understands the update mode, only needs the guide rail of user on to goods shelves to reequip so that install the electronic shelf label, need not installation work outside the increase.

Description

A kind of electronic shelf label based on MSP430

Technical field

The utility model relates to a kind of electronic shelf label, especially a kind of electronic shelf label based on MSP430.

Background technology

At present, known shelf label is papery, flourish along with retail trade, the kind of commodity gets more and more, the advertising campaign of extensive stock is frequent, for the adjustment problem of shelf label, single dependence manual maintenance can not be met the need of market, and such work is not only lost time but also lavish labor on.Add up according to associated mechanisms, the error rate of people is generally 1/200, if the price change of commodity is frequent, inevitably will occur that price updating not in time or upgrade the situation of makeing mistakes, cause sticker price and commodity real price not to be inconsistent, present consumer more and more notices that whether the price of label in market is consistent with commodity real price, not only has influence on consumer if there is inconsistent phenomenon, also can have influence on the prestige of businessman, and then affect the sales volume.Not only cost is high for the way of artificial replacing Commercial goods labels, and the probability of makeing mistakes is large, and also can have influence on consumer and businessman oneself, the appearance of electronic shelf label well solves this problem.

Utility model content

Technical problem to be solved in the utility model is all: electronic shelf label used in the market, the problems such as ubiquity stand-by time is short, and Costco Wholesale is high, and communication is unreliable.

The utility model solves the technical scheme that its technical matters adopts: the utility model provides a kind of electronic shelf label based on MSP430, be the electronic module adopting wireless communication technique, there is Presentation Function and certain storage capacity, it is characterized in that: structure comprises electric drive module, wireless communication module, display module and power module; This label adopts low-power chip as CPU; And select the communication module possessing wireless awakening function, realize price updating and wake up in real time; Display adopts Electronic Paper, the only power consumption when price refreshes; Display module increases temperature sensor chip, carries out temperature compensation, be applicable to-20 ~ 70 DEG C wide temperature range scopes to label; Power module increases electric quantity acquisition part, monitoring battery electricity, and automatic-prompting changes battery.Be connected with intermediate equipment by wireless communication module, send order by intermediate equipment to corresponding electronic shelf label, appraised at the current rate by both-way communication real-time follow-up and issue, feed back successful information of appraising at the current rate in time.Each electronic shelf label has one unique No. ID, avoids the situation that electrovalence signs for wrong data occurs.

The beneficial effects of the utility model are, by wired or wireless mode real-time update module displaying contents, and in time update status can be fed back to terminal, convenient operation person understands more new state.Change one-shot battery and can use 2-3, the maintenance cost reducing user is low.The utility model only needs user to reequip the guide rail on shelf to install electronic shelf label, without the need to increasing extra installation work.
