Description

Information Management System and Method with RF-ID Multiaccess Reader.

The present invention relates to a system for simultaneously managing a plurality of pieces of management information by using RF ID Tag (Radio Frequency Identification Tags), and recording / processing to manage information of an object having ID and information.

More specifically, the RF ID Tag is recorded by managing a variety of information, including the manufacturer, the date of manufacture, the unit price and quantity, inventory information, movement information, and sales information, etc. in a non-contact manner using the RF ID tag. The present invention relates to an information management system that records and reads information of an article in an RF ID to manage the article from production of the article to logistics, storage, sale, and after-sales service.

In general, a bar code system and a self-recognition system are most commonly used for a point of sale (POS) system or a goods management system for recognition and information management of a specific object. The barcode system attaches an attachment formed with a bar pattern to a management object and manages the information by reading the bar pattern, and the self-recognition system writes predetermined information in the magnetic bar of the magnetic card and reads it by the reader. To manage information.

Conventional bar code system was not possible due to the damage of the bar code, the recognition of the bar code was made using the handling of the operator or the proximity recognition device. Also, if the information of the goods changed after production, it could not be retained. Therefore, there were many limitations in terms of utilization and many difficulties in using.

Magnetic recognition system has a lot of errors in reading or preserving the information recorded on the magnetic card, there is a problem in that there is a lot of limitations in use because the reader is configured as a contact type.

In order to read the information of the target, the conventional system described above has a problem in that one handling is required to read one target information, and it is difficult to grasp when the movement of the target occurs without handling by the administrator.

As described above, the conventional recognition system based on barcodes and magnetic apparatuses requires the recognition of information by human help, can only take information on one object in more than one operation, and maintain the state necessary for recognition. Due to the drawbacks, the use of RF ID technology in automation and data collection and management systems is being actively investigated, and in particular, it is required to apply more to the management of goods information.

An object of the present invention, by attaching the RF ID Tag recorded the management information to the management object to record specific information about these, and comprehensive management of the information according to the occurrence of changes, such as storage, movement and sales of the object The present invention provides a system for more efficient information management by simultaneously reading a plurality of pieces of target information.

In addition, since a plurality of target information can be simultaneously read in real time, a plurality of target objects can be automatically recognized and processed in real time to provide a more effective information management system.

The RF ID recognition and processing apparatus includes an antenna device 100 for supplying operation power to the plurality of tags and performing wireless communication, a wireless processing unit 310 for performing wireless communication with the plurality of tags, and the wired / wireless It is preferable to have a wired or wireless data processing device 320 for communicating with the host computer through a network.

The control method of the information management system using the simultaneous reading of the RF ID according to the present invention, in the information management system using the RF ID recognition and processing apparatus installed to read the information of the RF ID Tag and the RF ID Tag, Checking / checking the presence or absence of the tag (①) and reading the information of the tag (②) are performed by the RF ID recognition and processing apparatus. When the tag information is confirmed, the tag information is transmitted to the host computer. Step (③) is performed in the control device, it is preferable that the tag has a data collision prevention (Anticollision) function to read a plurality of tag information at the same time in the RF ID recognition and processing device.

The RF ID recognition and processing apparatus preferably transmits and receives a signal including specific information of a tag in a request signal so that a plurality of tag information can be read at the same time, and transmits and confirms tag information to the host computer. The process may be further provided.

Detailed embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, according to the embodiment of the present invention, a tag 10 is provided for each target requiring information management, and an antenna device for transmitting operating power to the target tag 10 and enabling wireless communication with the tag ( The RF ID recognition and processing apparatus 200 including 100 is connected to the host computer 203 through a wired / wireless communication network, and the RF ID recognition and processing apparatus 200 with the host computer 203 through the wired / wireless communication network. ) Is configured to allow bidirectional information transmission.
