Embodiment

As shown in Figure 1 and Figure 2, the wireless electron price tag is the electronic module that adopts wireless communication technique, has Presentation Function and certain storage capacity.Its principle is to carry out communication by wireless communication module and electronic scales, when the price of certain product in the commodity storehouse in the electronic scales changes, electronic scales sends order by Centroid to corresponding wireless electron price tag, appraising at the current rate by the both-way communication real-time follow-up issues, in time the feedback successful information of appraising at the current rate.Each wireless module has one ID number, so just the situation that wireless module is received wrong data can not occur.The wireless electron price tag is comprised of electric drive module, wireless communication module, display module and power module.

The present invention's (being called for short Scale-ESL), be a kind ofly be placed on the shelf, the electronic display unit of alternative traditionally on paper price tag, each Scale-ESL links to each other by the weighing electronic scale of wireless network with bulk goods districts such as prepared food, fruits and vegetables, and up-to-date commodity price is shown by the liquid crystal display on the Scale-ESL.It is very obvious for the interests that the retailer brings, and at first revises simple that price work becomes, and has also saved day by day expensive labour cost simultaneously, the environment that appraises at the current rate that Scale-ESL provides convenience, and the supermarket can be carried out more sales promotion and be promoted sales volume; Secondly the commodity shelf show the consistent risk that reduces the governmental price supervision with the cash register price, also satisfy the hope that client thirsts for obtaining accurate price simultaneously.

The complete Scale-ESL system of one cover comprises that principal computer PC, electronic scales, Centroid and terminal node (electronic tag ESL) four parts form.When merchandise news that lane database exist to need upgrades, reach electronic scales under at first wired by super incity by principal computer, the wireless network; Electronic scales is according to the commodity storehouse of the information updating oneself of receiving, and to its work coding processing, the pricing information that then will need to upgrade is sent to Centroid by serial ports; The RF radio signal that the Centroid driven antenna will be loaded with commodity data information is sent to the 30m radius region scope centered by electronic scales; Electronic tag ESL is one by one with the wireless data receiver of ID address, and they can be reduced into effective digital signal with the RF signal that receives and show, and in time feedback information is updated successfully to Centroid.Centroid is integrated in the electronic scales.

The ID address of each ESL needs to use special-purpose serial port connecting wire and special software to upgrade by computing machine.

The button cell power supply of the inner section of ESL, present ESL product power consumption is all very low, and each battery generally can be worked 1 to 3 year.Change the expense of one-shot battery about 1.2 yuan, so the maintenance cost of ESL is quite cheap.ESL is placed on the special shelf erecting frame, has the anti-structural design of stealing, the salesman can with one such as the specific purpose tool of key size with its taking-up or replacing position.
