RFID warehouse management system

First, the system introduction

With the acceleration of economic globalization and the importance of modern logistics to economic development, China's logistics industry is in a period of rapid development. In the future market competition, the competition of enterprise supply chain is decisive. . The socialization and specialization of production has led more and more enterprises to outsource logistics and supply chain management functions to professional logistics companies to reduce costs and reduce inventory. This trend has brought great opportunities to China's traditional logistics enterprises, but also brought challenges - only to meet the customer's demand for logistics services to the maximum extent, to minimize the cost of logistics services, Only by gaining the trust and profit of the company can you get business opportunities. Therefore, traditional logistics enterprises such as port terminals, freight companies, storage and transportation companies, freight forwarding companies, logistics departments of manufacturing enterprises, and new type of third-party logistics companies only update their concepts and make full use of modern logistics technology to achieve their business objectives. The accuracy and timeliness of information is the key to supply chain and logistics management. This is precisely the most prominent advantage of RFID (radio frequency identification) technology. The goods are labeled with RFID tags, and the system can be used without opening the outer packaging of the product. Identification is carried out in boxes to accurately obtain relevant information about the products, such as types, carriers, origins, destinations, transportation links, and the like. RFID (radio frequency identification technology) system can realize real-time monitoring of goods from raw materials, semi-finished products, finished products, transportation, warehousing, distribution, shelves, final sales, and even return processing, which not only greatly improves the degree of automation, but also can greatly reduce The error rate, which significantly improves the transparency and management efficiency of the supply chain; the application of RFID in the logistics industry helps enterprises to reduce costs and gain competitive advantage. The smooth flow of information is beneficial to control and reduce inventory, and reduce costs (including labor costs). The RFID logistics management system enables logistics companies to manage the storage, distribution, distribution and transportation of goods more efficiently, accurately and scientifically.

Second, RFID (radio frequency identification) technology principle RFID technology is a contactless automatic identification technology, the basic principle is to use the radio frequency signal and its spatial coupling, transmission characteristics, to achieve automatic machine identification of the object to be identified in stationary or moving . A radio frequency identification system generally consists of two parts, an electronic tag and a reader. In the application, the electronic tag is attached to the item to be identified, and when the item to be identified with the electronic tag is in the read range, the reader automatically takes out the appointment identification information in the electronic tag in a contactless manner (the reader can Simultaneous reading of data of 50 or more tags), thereby realizing the function of automatically identifying items or automatically collecting item identification information.

Third, the system features RFID wireless instant long-distance reading mode, large capacity and high-speed data processing capabilities and a high degree of automation, making it an irreplaceable technical advantage;
Data such as goods and trucks can be checked and managed in real time on the Internet;
Virtual inventory tracking;
The system is easy to install and maintain;
Data acquisition is efficient and accurate;
The system tracks all logistics links such as people, goods, pallets, forklifts, trucks, etc. in real time;
All aspects and processes of logistics are monitored in real time.

Fourth, system composition 1, reader: This system uses ThingMagic UHF UHF915MHz reader, respectively, ThingMagic fixed installation reader and ThingMagic handheld UHF RFID reader, the reader senses the tag through the antenna, and reads the tag Data information. Fixed-mount readers can read labels up to eight meters, while handheld readers read about one meter.
2, label: label has a variety of styles, such as card type, credit card size, installed in trucks, containers, installed in trays, goods, parcels, labels in a variety of package forms, can be targeted. Each tag has a globally unique ID number. In actual applications, it is given information on the objects and goods being installed for identification, reading, and recycling. The label can be attached to the object to be identified very conveniently.
3. Management software: After obtaining a large amount of tag data, the reader can directly access the port of the computer/PDA/laptop, and automatically input the system database in real time, which is managed by the management software. The management software is online, which means that on any Internet computer in the world, managers or users can check and manage the goods in real time and understand the location of the trucks. The information is uploaded to an ordinary Internet platform, so that the visual scene of the end-to-end real-time movement of the goods can be obtained.

Fifth, the system realizes warehousing and distribution management:
1. The card reader and the entrance and exit of the warehouse are installed with a card reader, so that when the tagged pallet, forklift, goods, etc. are entered into the reading area, they are automatically recognized, recorded, and transmitted to the system database for storage; When the goods leave the distribution center, the reader at the passage port reads the information on the label and transmits it to the processing system to automatically generate the delivery list; after the truck arrives at the destination warehouse, the reader automatically picks up the vehicle from the receiving port. The goods on the direct scan can quickly complete the acceptance and check;
2. The label is installed on the car and the pallet, and the management system can track the orientation of the forklift and the pallet at any time. The reader is installed above the access port of the forklift, the tray in and out of the warehouse, and each tray is equipped with a radio frequency tag. When the forklift is loaded with the pallet goods, the reader makes the computer know which pallet goods have passed. The system handles a large number of pallet goods on a daily basis, which can greatly improve efficiency and ensure that the relevant information of the goods is accurate and reliable;
3. Install the label on the goods and parcels. The management system can track the real-time tracking in the various links and processes of the logistics through the fixed installation reader and the handheld reader, which is convenient for inventory, search and comparison. Convenient for inventory, the staff can collect and sort the data from the system to clearly grasp whether the goods in the warehouse are out of date, etc.; to find the goods, suppose we use traditional methods to find a certain item in a large number of stacked pallets, it requires a lot of work. With the RFID system, the search process becomes so simple, the staff only needs to hold the handheld reader to scan the relevant area to easily find the goods that need to be found. Because of the penetrability of the radio frequency, even finding a small tagged item in the depths of the package can be done easily;
4. Install the reader above the cargo conveyor. When the cargo passes through the conveyor belt, the system quickly obtains the information of the cargo through the reader, and immediately passes the original data in the computer and the system to make a comparison. The RFID management system can completely abandon the traditional method of using paper documents to complete the sorting of goods, improve efficiency and save labor; not only can quickly complete the storage of simple order, but also can easily be based on the size of the goods, the speed of delivery, and loading and unloading requirements. The storage and extraction of complex goods can be realized; the sorting workers can realize the automatic storage, delivery, packaging, loading and unloading operations of the goods with simple operation, which reduces the labor intensity of the workers, improves the efficiency, and most importantly, It can handle this process at high speed and without error;
5. The staff or the forklift driver can check the goods in the warehouse through the hand-held card reader for information collection, find, fast and convenient, greatly improve the inventory count, check the efficiency and accuracy of the goods.
6. When the goods arrive at the destination, the staff can check the arrival goods very quickly by taking the handheld card reader, and the incoming database comparison will not cause the mis-recording of the traditional record, because it can be remotely sensed and accurate at the same time. Handling 30 labels greatly improves the efficiency and accuracy of the work;
7. The staff member carries a label. When the staff moves in the warehouse, they will be tracked by the entrance and exit and the reader installed above the warehouse space, and the running time and trajectory of the staff will be recorded to conveniently monitor the work of the staff. Examine the efficiency of the staff;
8. The RFID system is used for intelligent warehouse storage management. RFID completely and effectively solves the management of information related to the movement of goods in the warehouse. It not only increases the number of pieces of goods handled in one day but also monitors all the information of these goods. The information is stored in the central computer of the warehouse, and when the goods are loaded and shipped to another location, another reader recognizes and informs the computing center which trailer it is placed on. In this way, the management center can know in real time how many goods have been processed and how many goods have been sent, and can automatically identify the goods and determine the location of the goods;
9. The simultaneous use of fixed installation readers and handheld readers makes on-site operations such as on-site data collection, inventory, inbound and outbound management, and location inspection clear, accurate, systematic, and scientific;
10. The truck will be automatically read and recognized by the reader before leaving the warehouse, and the obtained information will be automatically transmitted to the background management system, and the system will immediately compare with the original data in the database. When the wrong information, missed transportation and other information are found, the system will automatically alarm to prevent the truck from leaving the warehouse and ensure the absolute accuracy of the cargo transportation.
