Description

Network system for electronic price display {NETWORK SYSTEM FOR ELECTRONIC PRICE DISPLAY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to short-range wireless communication technology, and more particularly, to a network system for electronic price display based on short-range wireless communication technology.

There are the following problems in using large stores such as discount marts and department stores.

First, shortage is likely to occur because inventory management is not made at the same time of purchase, and there is a limit to preventing theft with a conventional barcode device.

Second, the shelf level displays only simple information such as product type and price, so there is a limit in providing information and inducing purchase, and it is difficult to manage the selection level according to the change in the display of the product.

Third, since multiple tag data is transmitted to the gateway through one router, the traffic of the network is likely to be overhead. As a result, there is a high possibility of collision between data.

An object of the present invention is to provide an electronic price display network system that can minimize network traffic by collecting and merging into sub-networks for each merchandise display rack.

In addition, another object of the present invention is to provide a network system for displaying an electronic price that can easily manage inventory to prevent theft of goods.

In addition, another object of the present invention is to provide a network system for displaying an electronic price, which is easy to manage the selection level according to the change of merchandise display.

According to the present invention, there is provided a network system for displaying an electronic price, each of which displays a product with an electronic label tag; Respective merging routers arranged in correspondence with the respective sub-networks to read tag data from the electronic label tag of the merchandise displayed on each merchandise display rack, and merge the tag data into one data; And a gateway configured to receive data transmitted from each merge router and transmit the received data to the data server.

Preferably, the electronic label tag, merging router and gateway includes a Zigbee device for wirelessly transmitting and receiving tag data including product information.

According to the present invention, the network traffic can be minimized by collecting and merging into sub-networks by merchandise shelves, and it is easy to manage inventory to prevent theft of goods, and manage selection levels according to changes in merchandise displays. There is an easy effect.

Hereinafter, exemplary embodiment (s) of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the elements of each drawing, it should be noted that the same elements are denoted by the same reference numerals as much as possible even if they are displayed on different drawings. In addition, many specific details are shown in the following description, which is provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. Will be self-evident. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram of a network system for displaying an electronic price according to the present invention.

According to the present invention, a network system for displaying an electronic price is displayed on a plurality of merchandise shelves 111, 112, and 113 and respective merchandise shelves 111, 112, and 113 on which merchandise with an electronic label tag 400 is displayed. Each merging router 131, 132, and 133 arranged in correspondence with the respective sub-networks to read the tag data from the electronic label tag of the product and merge the tag data into one data, for each merging The gateway 140 receives data transmitted from the routers 131, 132, and 133 and transmits the data to the data server 150.

Here, each of the electronic label tag, the merging router and the gateway includes a Zigbee device to wirelessly transmit and receive tag data including product information.

2 is a block diagram schematically illustrating the components of a Zigbee device according to an embodiment of the present invention.

The Zigbee device includes an antenna 311, an RF receiving module 312, an RF transmitting module 315, a phase locked loop (PLL) 313, a power control circuit 314, a pulse processing module 316, and It comprises a control module 317.

The RF receiving module 312, the RF transmitting module 315, the phase synchronization circuit 313, and the power control circuit 314 are components that process operations corresponding to the PHY layer S5 of the Zigbee protocol stack. And network topology.

The phase synchronizing circuit 313 provides an oscillation frequency signal so that the RF receiving module 312 and the RF transmitting module 315 synthesize an intermediate frequency signal, and the power control circuit 314 determines the strength of the received signal to transmit the amount of transmission power. Performs the function of adjusting.

The RF receiving module 312 and the RF transmitting module 315 use a DSSS (Direct Sequence Spread Spectrum), and in the 2.4 GHz band, an Off-Quadrature Phase-Shift Keying (O-QPSK) modulation scheme of 32 PN code length is used. For the sub-1 GHz band, a Binary Phase-Shift Keying (BPSK) modulation scheme of 15 PN code length is used.

When the MAC (Media Access Controller) processing module 316 finishes the digital processing of the PHY layer S5, the MAC module analyzes the transmitted data frame structure to approve the frame and detects an error (Error Detection; CRC or Checksum). Detects whether to retransmit, and handles packet routing.

In other words, the pulse processing module 316 is a component for processing an initial hardware network connection, and provides an additional frame structure related to a beacon for time synchronization and a guaranteed time slot (GTS). In addition, the channel access is handled by a carrier sense multiple access with collision avoidance (CSMACA) method.

On the other hand, the control module 317 is a function of the remaining MAC layer (referred to as "Software-MAC" corresponding to the hardware module (Hardware-MAC)), the function of the network layer (S3), the function of the framework layer (S2) By configuring the network topology, and performs the function of the application layer (S1) to process digital data.

As described above, although the specific embodiment (s) have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiment (s), but should be defined by the claims below and equivalents thereof.
