Abstract

The utility model discloses a warehouse management system based on RFID technique, regional and the interior region of storehouse outside the storehouse, regional and the interior region of storehouse in between link to each other through access control system, access control system in be equipped with RFID equipment and two at least gratings, grating and a plurality of host computer link to each other. When materials are in and out of the warehouse, when the materials are more, a single RFID reader may have a phenomenon of missing scanning due to the fact that the coverage area is not large enough, but electronic tags on the materials are scanned for multiple times, and the material information read by each RFID reader is collected in a data management system, so that the phenomenon of missing scanning can be greatly reduced.

Description

Warehouse management system based on RFID technology

Technical Field

The utility model relates to a warehouse management system based on RFID technique.

Background

The RFID technology, that is, Radio Frequency Identification (RFID), is one of automatic Identification technologies, and performs non-contact bidirectional data communication in a Radio Frequency manner, and reads and writes a recording medium (an electronic tag or a Radio Frequency card) in a Radio Frequency manner, so as to achieve the purpose of identifying a target and exchanging data.

In warehouse management systems, RFID technology has been applied, which is based on the principle that an RFID device is installed at the entrance of a warehouse and an electronic tag is installed on a material, so that the material can be identified and registered when entering or exiting the warehouse, but the system has some defects;

firstly, the RFID technology can only identify when the electronic tag passes by, and cannot judge whether the materials are put in or out of a warehouse;

secondly, if the range of the wireless radio frequency is too large, the materials which are put in storage are easy to scan repeatedly;

thirdly, if the range of the wireless radio frequency is set to be too small, the phenomenon of missing scanning can occur;

therefore, an accurate warehouse management system based on the RFID technology is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a warehouse management system based on RFID technique in order to solve the not enough of above prior art.

The utility model provides a warehouse management system based on RFID technique which characterized in that, includes the regional and the interior region in storehouse outside the storehouse, regional and the interior region in storehouse between link to each other through access control system, access control system in be equipped with RFID equipment and two at least gratings, grating and a plurality of host computer link to each other.

Preferably, the number of the gratings is five, three of the gratings are located in the out-of-library region, and two of the gratings are located in the in-library region.

Preferably, three of the five gratings are connected with the RFID equipment, and two gratings are connected with the RFID in-out warehouse judgment host.

Preferably, the interior of the warehouse is internally provided with a plurality of material storage cabinets, the cabinet doors of the material storage cabinets are glass doors, and the back surfaces of the cabinet doors are provided with metal shielding nets.

Preferably, the RFID reader includes a transceiver antenna, a frequency generator, a phase-locked loop, a modulation circuit, a microprocessor, a memory, a demodulation circuit, and an external interface.

Has the advantages that:

the utility model relates to an ingenious provides an accurate, convenient, effectual warehouse business turn over goods management system.

When materials are in and out of the warehouse, when the materials are more, a single RFID reader may have a phenomenon of missing scanning due to the fact that the coverage area is not large enough, but electronic tags on the materials are scanned for multiple times, and the material information read by each RFID reader is collected in a data management system, so that the phenomenon of missing scanning can be greatly reduced.

Drawings

Fig. 1 is a schematic diagram of the general structure of a warehouse management system based on RFID technology;

1. the system comprises a first grating 2, a second grating 3, a third grating 4, an RFID reader 5, a fourth grating 6, a fifth grating 7 and a material trolley.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

The warehouse management system based on the RFID technology comprises an area outside a warehouse and an area inside the warehouse, wherein the area outside the warehouse is connected with the area inside the warehouse through an access control system, and RFID equipment and five gratings are arranged in the access control system.

The first grating 1, the second grating 2 and the third grating 3 are all located in the area outside the library, and the fourth grating 5 and the fifth grating 6 are located in the area inside the library.

The first grating 1, the second grating 2 and the fourth grating 5 control the work of the RFID equipment, and when the material trolley passes through the gratings, the RFID reader 4 works instantly to record the condition of parts on the material trolley 7. Through the design of a plurality of groups of gratings, the repeated work of the RFID equipment is realized, and the effects of no missing scanning, no wrong scanning and no wrong scanning can be achieved.

When materials are in and out of the warehouse, when the materials are more, a single RFID reader may have a phenomenon of missing scanning due to the fact that the coverage area is not large enough, but an electronic tag on the materials can be scanned for 5 times, and the material information read by each RFID reader is collected in a data management system, so that the phenomenon of missing scanning can be greatly reduced.

The third grating 3 and the fifth grating 6 can be used for judging whether the trolley is delivered from the warehouse or put in the warehouse, and can be set through a program, and if the third grating 3 is triggered first, the trolley is put in the warehouse. And the design of the grating can realize the function of judging the warehouse entry and the warehouse exit. Therefore, the problem that the existing scheme cannot judge whether the materials are delivered into or out of a warehouse is solved.

Finally, a metal shielding net is added on the glass cabinet door of the original material storage cabinet to shield the signals of the electronic tags on the materials placed in the cabinet, so that the situation of repeated scanning can be greatly reduced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
