Create an intelligent warehouse management system around RFID technology

At present, competition in the domestic manufacturing market is becoming increasingly fierce, reducing operating costs and improving production efficiency have almost become the “slogan” of every company. However, how to truly achieve such an effect is indeed not easy to achieve. The intelligent warehouse management system implemented by Tianjin Little Bee with RFID technology is widely used in the logistics and warehousing industry. A complete set of intelligent warehouse management systems has been established to improve the efficiency of warehouse turnover, reduce the occupation of operating funds, and turn frozen assets into cash. The cost caused by the elimination of warehousing is an important link for enterprises to improve production efficiency.
Traditional warehouse management systems usually use manual warehouse management documents or barcode labels. These management models have obvious defects:
1. Manual entry, cumbersome work, large amount of data and error-prone, increase labor costs in warehousing
2. Barcode management, easy to copy, not stain-proof, not moisture-proof, and can only be read at close range and visible range
3. In and out of the warehouse, the inventory and counting are cumbersome and error-prone. The paper documents are easy to lose and damage and are not easy to save
4. The workload of manual inventory is large, resulting in a long inventory cycle, and missing goods or theft cannot be discovered in time
Functions and characteristics of intelligent warehouse management:
The goal of the intelligent warehouse management system is to establish a set of fast channels based on RFID technology to realize warehouse storage statistics and high-speed automatic recording of goods sent and received. The system uses RFID middleware as a platform to prepare multiple processes such as storage, inventory, and storage.
In recent years, RFID technology has entered the stage of commercial application.CurrentlyRFIDTechnology has been continuously combined with Internet and communication technologies, and has been applied to many fields such as industrial automation, commercial automation, transportation, logistics, supply chain management, public information services, etc., gradually realizing global item tracking and information sharing, greatly improving Management and operation efficiency, cost reduction, RFID technology is considered to be the most promising information technology in the application field of the Internet of Things.
The purpose of the intelligent warehouse management design around RFID technology is to realize the automation of the control of the entry and exit of the goods, the storage location and quantity statistics of the goods, and the information inquiry process, so as to facilitate the management personnel to carry out statistics, inquiries and grasp the flow of materials, so as to achieve convenience, speed, safety, High efficiency and other requirements.
Implementation of intelligent warehouse management system process:
Warehousing
In the finished product packaging workshop, workers first affix RFID electronic tags to the products, and then affix the box label after batch packing. If the pallet is required, the pallet label can also be affixed after the pallet is finished. The general labeling methods are:
1. Product single-piece labeling
2. Pack multiple products together, and label the outer packaging
3. The pallet is labeled and associated with the single product label or outer packaging label data
The packaged goods and products are passed through RFID by the loading and unloading toolReaderThe channel formed by the antenna is warehousing (the width of the channel can be set according to the distribution of the warehouse), and the RFID device will automatically obtain the warehousing quantity and send the information to the intelligent warehouse management system for storage. If it is directly transported on a pallet with a label, The cargo information of each pallet is written into the pallet label through the loading port reader and writer, and the order data association is formed at the same time, and then the storage location is calculated through the intelligent warehouse management information system (or manually designated the storage location for the batch at the beginning).
Out of stock
The consignor of the logistics department generates an outbound order according to the invoice required by the sales: that is, according to the outbound priority (such as the first out of the warehouse before the production date) to query the warehouse for the storage location and inventory status of the outbound goods, if there are customers The designated batch number will be queried according to the designated batch number, and the outbound cargo pick-up position and the corresponding pallet belonging to the goods will be generated.
The consignee brings the outbound order to the warehouse manager, and the warehouse manager checks the information to arrange for the forklift driver to carry out the corresponding product out of the warehouse.
The forklift picks up the goods through the exit gate, and the exit gate RFID reader reads the pallet label on the pallet to obtain the outbound information, and verifies whether the product batch number and location listed in the shipped product and the outbound order are correct.
After the delivery is completed, the warehousing terminal prompts the delivery details for the administrator to confirm, and automatically updates the data to the database. When the product is out of the warehouse, the system inventory is automatically reduced, so the inventory can only be changed through re-stocking or out-of-warehouse, otherwise it cannot be changed.
inventory
There is no need to manually check and inquire during the inventory. The warehouse management staff should use the smart inventory cart or handheld terminal to push over each shelf or pallet. The inventory cart/handheld terminal can read the quantity and type of goods on the shelf or pallet. And accumulate, when the inventory quantity does not meet a certain quantity, the system can give an alarm. After the inventory is completed, an inventory report is generated, and a comparison between the data information in the system and the actual inventory in the warehouse is provided for reference by the warehouse management personnel. At the same time, the data information in the system can be modified as needed to ensure that the goods and accounts are consistent, and a printer can also be connected Print directly into report form.
The warehouse manager can also use the handheld reader to search for the desired product at any time, and query the specific information of a specific product, such as: shelf life, storage date, box (bag or piece) quantity, etc.
For example, combining the receiving plan and pickup plan made by the supply chain planning system with radio frequency identification technology can efficiently complete various business operations such as designated stacking areas, shelf pickup and replenishment; enhance the accuracy and Fast, improved service quality, reduced costs, saved labor and inventory space, and reduced the loss caused by misplacement, theft, damage, inventory, and shipment errors in the entire logistics; no manual labor is required for inventory Inspections are faster and more accurate, and reduce wastage, reduce manpower; and provide accurate information about inventory conditions, management personnel can quickly identify and correct inefficient operation, so as to achieve rapid supply, and minimize storage costs .
Label recycling
When the warehouse manager confirms that the delivery is correct, the RFID electronic tag affixed (or hung) on the product is recovered for reuse by warehouse management.
