Abstract
The invention provides a new network arrangement method applied to an electronic shelf tag system and a corresponding communication mode. With regard to the region of the whole electronic shelf tag system, a zonal frequency reuse method is adopted, so as to guarantee the accuracy of communication and greatly improve the quantity of tags capable of being contained by the electronic shelf tag system.
Description
Technical field
The present invention relates to network arrangement method and communication mode in the electronic bin tag system.
Background technology
Along with the continuous development of retail trade, type of merchandize is more and more, and advertising campaign is more frequent, and the management of electronic article shelf label and replacing demand constantly increase.But increasing considerably of human cost and papery electronic shelf label cost develops to retail trade and brought resistance.Now, along with the application of wireless technology, the electronic bin tag system of papery electronic shelf label occurred being used for replacing, this system can revise the price of display of commodity in real time accurately.Such as; Notification number is in the patent document of CN201876908U; Mentioned a kind of electronic bin tag system, system is by a station server, a repeater; A plurality of electronic shelf labels and a portable electronic tag management devices are formed, and server is revised the price of respective electronic shelf label through repeater.This electronic bin tag system can be revised the price on the label in real time accurately, and has saved the cost of labor of changing.
In the electronic bin tag system that has occurred, communicate by letter between repeater and the electronic shelf label and generally adopted the radiowave of 2.4GHz wave band.We know, are subdivided into a plurality of frequency ranges again at the 2.4GHz wave band, how to utilize a large amount of electronic shelf label of management of these frequency range science, have become a problem that needs solve.
Summary of the invention
The present invention is exactly the problem that proposes for above solving.
The present invention proposes a kind of network arrangement method of electronic bin tag system, and proposed the corresponding communication mode according to this method for arranging.
At first, the network arrangement method of the electronic bin tag system of the present invention's proposition is: many repeater are arranged in electronic bin tag system, and every repeater and many electronic shelf labels communicate.The area dividing at whole electronic bin tag system place is become a plurality of regular hexagons, place repeater in each orthohexagonal central authorities, electronic shelf label is placed on needed position in this regular hexagon zone.Orthohexagonal zone can be regional seamless the coupling together at whole electronic bin tag system place, and accomplishing does not have the blind area, guarantees that the electronic shelf label of each position can communicate with respective repeaters equipment.
Secondly, the corresponding communication mode that the present invention proposes is: as stated, adopt the different frequency range in the 2.4GHz wave band to communicate in each regular hexagon zone.Like this, in intra-area communication, can not have influence on other zone.Simultaneously, because the transmission range of radiowave is limited, so can among two zones far away, use identical communication frequency; Accomplish channeling; Guaranteeing under the normal condition of communication, increasing the quantity in regular hexagon zone greatly, thereby increasing the quantity of electronic shelf label.
The beneficial effect that the present invention produces is that with the electronic bin tag system region, the division frequency is used, and under the prerequisite of the coverage rate that guarantees repeater and the accuracy of communicating by letter, has greatly improved the capacity of total system to electronic shelf label.
Description of drawings
Fig. 1 is the synoptic diagram of whole electronic bin tag system.
Fig. 2 is in the electronic bin tag system zone, is divided into the synoptic diagram in a plurality of regular hexagons zone.
Fig. 3 is the synoptic diagram in each regular hexagon zone.
Embodiment
Understand the present invention for clearer, be described in detail concrete embodiment below in conjunction with accompanying drawing.
Fig. 1 is illustrated in the actual application; Server is connected through Ethernet with a plurality of repeater; A plurality of orthohexagonal zones are arranged in the total system; Every repeater is positioned at the middle position in regular hexagon zone, and communicates through radiowave and electronic shelf label in the zone separately.The zone 1 of mark, zone 2, zone 3 and zone 5, because close together, each zone adopts different frequencies to communicate.But zone 1 is distant with the distance in zone 4, has adopted identical communication frequency.
Fig. 2 representes the total system region is divided into the synoptic diagram in a plurality of regular hexagons zone.Like figure, the prototype zone that dotted line draws is exactly the zone that electronic bin tag system need use, and orthohexagonal zonule can be with the seamless independently zonule that is divided into, this zone.For zones of different adopts different communication frequencys the space is provided.
Fig. 3 representes that in each orthohexagonal zonule, repeater is positioned at the center in zone, in this zone, many electronic shelf labels is arranged simultaneously, communicates by letter with it through radiowave.
Claims (4)
1. the network arrangement method of electronic bin tag system is divided into orthohexagonal isolated area with the electronic bin tag system region.
2. in the network arrangement method as claimed in claim 1, repeater is positioned at the center in regular hexagon zone.
3. in the network as claimed in claim 1,, adopt different frequencies to communicate for several close together or adjacent orthohexagonal zone.
4. in the network as claimed in claim 1,, can use identical frequency to communicate for two far away and non-conterminous regular hexagon zones of distance.
