KR200242623Y1 - A System for Customer Data and good in store with a RF Transciver - Google Patents

Abstract

The present invention relates to a stock and customer information processing device for store management, which is a device that can wirelessly send and receive inventory items and customer data required for work in the store, the device can be used wirelessly from a location close to the server The scope of usage is used for inventory management, which informs the item name and quantity of inventory items in the store, and other store management including manpower management. It is used for advanced after-sales service that records and informs customers in advance when parts are to be replaced.

The present invention consists of a system terminal (PDA) for transmitting and receiving customer information for a store, a server-side transceiving system (SPDA), and a database for a server. The system terminal (PDA) and the server-side transceiver system (SPDA) exchange data using an RF transceiver, and a plurality of PDAs are connected to one server.

In other words, since multiple PDAs communicate using the same frequency, it is a device designed to increase the utilization value of the frequency by introducing a token.

Description

A system for customer data and good in store with a RF Transciver}

The present invention relates to an inventory and customer information processing device for store management using RF transmission and reception, and more specifically, even if the same frequency is used by using a token and a packet, communication with each other only when it meets various requirements such as preamble and start byte. Therefore, the present invention relates to a stock and customer information processing device for store management using RF transmission and reception to enable communication with multiple PDAs using this.

In the conventional case, a commercially available store management program is expensive, and a user must directly use a server-side computer in order to access customer data for the purpose of inventory checking or after-sales service.

In this process, data leakage and mishandling were more likely to cause the server-side computer to fail.

Since many people had to use a single server, the staff at the store had to wait a lot of time to learn how to use the program.

The present invention is to solve the conventional problems as described above, because the user can access inventory management and customer data wirelessly through each terminal (PDA) without using a server-side computer directly, Tokens are secured, that is, tokens (TOKEN) are used because they need to communicate with multiple PDAs by sending and receiving to one server.

In addition, in order to communicate, it is possible to use a packet communication that attaches something back and forth when sending a single data, and to format it, which is not practical to use it directly. Its purpose is to provide a stock and customer information processing device for store management using RF transmission and reception so that a rapid after-sales service can be achieved by making a database even customer data by expanding the scope of application.

The present invention is to wirelessly connect one or several terminals (PDA) and a server (computer) for the database and applications, a computer and the terminal (PDA) for easy use in the field to achieve the above object Server side transceivers.

Terminal (PDA) can query and search the information of the database wirelessly, can be actively used for inventory management and logistics system.

Description of the configuration and operation of the inventory and customer information processing device for store management using the RF transmission and reception according to the present invention will be described in detail through an embodiment of the present invention.

The accompanying drawings, Figure 1 relates to a system diagram for the overall configuration according to the present invention, a system terminal (PDA) and server-side transmission and reception system for transmitting and receiving customer information for the store 20 and the database for the server 10 It consists of.

2 is a schematic diagram of a server-side transmission and reception system according to the present invention, and a power supply unit 21 for converting a constant voltage 5 [V] to supply power to a device, a control unit for displaying and processing a liquid crystal display (LCD) and data. (25), the transmitter and receiver responsible for RF transmission and reception, and a connection unit 22 for connecting to the server 10 and RS-232C communication.

3 shows a frame structure for a signaling method according to the present invention.

The terminal PDA of the present invention reads whether the data received from the server 10 is its own, discards the data if it is not its own, and displays the data in an appropriate form on the LCD window when it is read as the data entered into the terminal.

In addition, the transmitting and receiving units 23 and 24 are configured in such a state that the antenna switching module is inserted so that the data of the transmitting unit 23 does not affect the receiving unit 24.

The operation and effects of the present invention, which are configured as described above, will be described in detail by way of examples.

(Example)

The server 10 of the present invention transmits and receives tokens to communicate with multiple terminals PDA, transferring the server side data while passing the token to the first terminal PDA1, and again from the terminal PDA1. While receiving the request data and input data of the terminal (PDA1) is sent again.

As the token is passed back to another terminal (PDA2) and the above process is repeated, several terminals (PDAs) and servers continue to exchange data to manage goods and customers in the store.

The server and the terminal (PDA) are divided into the following areas.

Input area that displays the desired data on the screen and is in direct contact with the user who receives data from the keyboard,

A network area that generates a sending CRC for the data to be sent,

After data transmission is completed, request for retransmission in case of error through CRC check, etc., examine the control area to determine what command is desired, and prepare to send in bundle by sending transmission data. In other words, it is classified as a Data Link Control Layer that is made in a Frame Format.

If the preamble is checked and corrected, it is classified into a medium access control layer and a hardware area.

As shown in FIG. 3, the structure of the frame is as follows.

Preamble signal: 5 byte signal or byte signal.

MA stands for Master Address and stands for Base Terminal (Server) side computer.

SA: Address of slave which communicates with master.

CF: It is a place to control signal and decides the type of frame.

Using the first bit as a flag, the current frame determines whether the master sends it to the slave or the slave sends it to the master.

Seq. #: Only present in data frame. If the frame is a data frame, this indicates the number of frames received.

Data

CRC: Check sum of entire frame from Preamble

When RF data is transmitted and received in the layer and frame structure configured as above, several PDAs can be connected to one server.

Due to the present invention, information for goods inventory and customer A / S can be provided quickly, so that it can proactively cope with the situation in the field. Various functions are possible with one program, and the database can be managed safely and efficiently, and the management cost can be greatly reduced by the advancement of the logistics system. Another concept is Token, which can be used by several PDAs at the same time, thus saving limited frequency resources.

Although the present invention has been described with reference to specific preferred embodiments, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the scope of the present invention. Various changes and modifications can be made by the user.
