I. Project Introduction An automated warehouse system (AS/RS) is a crucial component of enterprise logistics. As a logistics system, it utilizes advanced technology to improve operational efficiency, rationally control inventory levels, reduce logistics costs, and continuously improve enterprise management, thereby enhancing economic benefits. However, the inbound operation, as the entry point to the AS/RS, often becomes a bottleneck in the overall system's efficiency due to limitations in the process flow, sometimes even hindering the AS/RS's effectiveness. Before goods are received, automatic barcode identification, automatic dynamic weighing, and relabeling are often required. Only by coordinating these processes can the system operate efficiently and correctly. Furthermore, the system needs to automatically alarm for various anomalies. Operators can quickly restore the system to normal operation by correctly handling these alarms. II. Process Flow The inbound conveyor line equipment consists of conveying, automated barcode scanning, weighing, and relabeling systems. Goods are transported from the truck bed onto the conveyor belt, passing through a fixed barcode scanner that reads the barcode information affixed to the goods. The barcode information is transmitted to the host computer via serial port for storage, and the remote basic information database is retrieved based on the corresponding fields in the information to obtain other information about the goods. The goods are conveyed to the dynamic weighing system via conveyor belt, the weight of the goods is weighed, and the information is sent to the computer via serial port. The computer arranges the weight information of the goods and other relevant information in a queue, generates the required barcode according to certain rules, and sends it to the automatic labeling machine. At the same time, it is written into the remote warehouse management system (WMS) database for use in outbound operations. The process flow diagram is as follows: Figure (I) III. Project Scheme 2.1 Electrical Control System Structure Diagram (II) 2.2 Configuration Software Processing The configuration software plays an important role in this system, and its specific functions are as follows: 1. The PLC reads the barcode information, and the configuration software decomposes and analyzes the barcode string to obtain the field information. 2. Through the serial number information in the barcode information, the remote SQL SERVER data table is accessed to obtain more information about the goods from the data table. 3. 4. Match the weight of the goods weighed on the dynamic weighing machine with the weight of the goods. 5. Calculate the net weight based on the gross weight and the box settings. 6. Generate a new barcode according to the agreed rules. 7. Send the barcode to the automatic labeling machine. 8. If the barcode is successfully affixed, write it to a remote SQL SERVER table for use by the WMS system. The host computer interface is shown in Figure (3) below. To date, the system has been running successfully for one year. During operation, its performance has been stable, and various alarm detections are very complete, which has won praise from customers.
