[0018] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following specifically cites a preferred embodiment and describes it in detail with the accompanying drawings as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 The following is a schematic diagram of the workflow of a warehouse management system based on radio frequency identification according to the present embodiment. DETAILED DESCRIPTION

[0020] In order to make the content of the present invention more clearly understood, the present invention is further described below based on specific embodiments in conjunction with the accompanying drawings.

[0021] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0022] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] like Figure 1 As shown, a warehouse management system based on radio frequency identification includes RFID electronic tags, shelves, radio frequency identification devices, security inspection devices and control processing devices. Passive, high-frequency (915MHz) RFID electronic tags are used. Each tag is pre-stored with unique cargo information, including key data such as cargo name, cargo weight, shelf number, and cargo entry time. These tags are firmly affixed to the outer packaging of the cargo for long-term identification and tracking in the warehouse environment. The cargo is placed on the shelves. The shelves in the warehouse are designed to be adjustable so that they can be adjusted according to the size and weight of the cargo. The radio frequency identification device is installed on the shelf and connected to the control processing device, and the control processing device is connected to the security inspection device.

[0024] The radio frequency identification device includes multiple RFID high-frequency identifiers and antennas, which are installed in prominent positions on each shelf. These devices are connected to the control processing device via wired or wireless means to ensure that RFID identification can be performed instantly when the goods are placed or taken out.

[0025] The security inspection device is mainly composed of an image acquisition and judgment module and an alarm module. The image acquisition and judgment module is installed at the entrance and exit of the warehouse and connected to the control processing device. The alarm module is used to output alarm information. The RFID high-frequency identifier performs radio frequency identification on the goods to obtain radio frequency identification information and sends it to the control processing device. The image acquisition and judgment module uses a high-resolution camera and image processing algorithm to monitor and count the goods entering and leaving the warehouse in real time. The control processing device verifies multiple radio frequency identification information with the corresponding goods outbound information. Once it is detected that goods are leaving the warehouse, the module will immediately generate outbound information and send it to the control processing device for verification. If the verification fails, the alarm module will start and emit alarm signals such as sound, vibration or flashing LED lights.

[0026] The control and processing device is the core part of the entire system, including the collection control module and the remaining storage position display. The collection control module has a built-in processor, database and controller, and is responsible for receiving data from the RFID high-frequency identifier and the image acquisition and judgment module for storage, analysis and processing. If it is detected that the goods outbound information does not match the RFID identification information, the processor will immediately trigger an alarm instruction and send it to the alarm module through the controller. The remaining storage position display will update the shelf usage in real time according to the processor's instructions, providing warehouse managers with intuitive shelf allocation information.

[0027] Through the above implementation, the present invention provides a warehouse management system based on radio frequency identification. When new goods arrive at the warehouse, the warehouse manager will first attach an RFID electronic tag to the goods and enter the goods information into the system database. Then, according to the indication of the remaining storage position display, the goods are placed on the designated shelf. In this process, the RFID high-frequency identifier will automatically identify and record the location and information of the goods; when it is necessary to leave the warehouse, the warehouse manager will find the corresponding goods according to the information on the delivery list. When the goods are taken out and pass through the security inspection device, the image acquisition and judgment module will record the delivery information of the goods and send it to the control processing device for verification. If the verification is successful, the goods can be shipped smoothly; if the verification fails (for example, the goods shipped out do not match the information on the delivery list or are not uploaded to the delivery list), the alarm module will immediately start and send an alarm signal to remind the warehouse manager to register the delivery information. With the entry and exit of the goods, the use of the shelf will change continuously. The control processing device will also update the information of the remaining storage position display in real time according to the data provided by the RFID high-frequency identifier. In this way, the warehouse manager can understand the use of the shelf at any time and make adjustments and optimizations as needed.

[0028] To sum up, the beneficial effects of this embodiment are as follows: this embodiment integrates RFID electronic tags, smart shelves, radio frequency identification devices, security inspection devices and control processing devices. The radio frequency identification device installed on the shelf reads the cargo information in the RFID electronic tag in real time, and verifies it with the outbound information recorded by the image acquisition and judgment module of the security inspection device, thereby realizing rapid tracking and monitoring of cargo. Once an abnormality is found, the alarm module immediately sounds an alarm to ensure warehouse safety. Overall, the system not only realizes the automatic identification, tracking, outbound verification and shelf management of warehouse cargo, but also significantly improves the efficiency, accuracy and flexibility of warehouse management, reduces labor costs, and enhances the safety and traceability of cargo management.

[0029] The embodiments described above are only preferred implementation modes of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and modifications made by those skilled in the art on the basis of the invention shall fall within the protection scope of the present invention.
