In a typical warehouse, the truck returns to the dock door to unload the goods on the pallet. The pallet or container has a Radio Frequency Identification (RFID) label (currently, low-priced goods cannot have their own labels). The warehouse is divided into different locations with corresponding identification electronic codes, and the RFID reader can be installed inside the warehouse entrance and warehouse. The entire warehouse and the vicinity of each entry are covered by the network (wireless or wired) for information sharing. A typical RFID system consists of a radio frequency tag (RFIDTag), a reader (RFIDReader), and application support software. The electronic tag consists of a chip and an antenna, each chip having a unique identification code. The tag can be attached to the identified item. When the identified item with the electronic tag passes within the readable range of the reader, the reader automatically recognizes the tag and sends the information to the backend software, thereby implementing automatic The ability to identify items or automatically collect item identification information. Intermediary between the front-end RFID reader hardware module and the back-end database and application software, called RFID Middleware (RFIDMiddhware). The application side uses a common set of application programming interfaces (APIs) provided by the middleware to connect to the RFID reader to read the RFID tag data. The middleware implements precise control of the underlying device, collects raw data in real time, filters the data, and encapsulates typical application logic therein, so that the system interface is simple and transparent, thereby achieving system coordination. 1 simulated warehouse environment To develop middleware, you first need to simulate the warehouse environment. Due to the price of the label, it is not possible to label each item and only track the goods by marking the tray. As shown in Figure 1, the RFID tag card is installed and worn on each pallet, forklift and inbound and outbound personnel, and the reader/writer is installed at the shop and warehouse entrances and exits, and the RFID tag is taken through the entrance and exit through the reader/writer. The information of the warehouse attached to it is bundled into the database with the RF card, and the forklift and personnel's inbound and outbound conditions are recorded. Install the camera at I:1 and judge the number of goods passing through the entrance and exit. The system distinguishes the human library object by the category of the RFID tag, and through the rules that the warehouse management personnel and the staff member abide by, when the RFID tag is read, the human bank condition is judged, and the state of the tray is judged by the video image (empty or full) And the quantity of goods loaded), thereby calculating the number of product outlets. Conduct statistical analysis on a regular basis to provide decision support for managers and to alert when an abnormal situation occurs.
