The RFID channel type reading device is installed at the storage port, and the batch label information of the goods is read and uploaded to the background management system when the storage is completed, and the bulk storage of the goods is completed;
After the goods enter the warehouse, وسيتم فرزها وفقا للمواصفات, put into the storage area of the corresponding kind, and an identification card will be installed for each storage place, and each identification card will be labeled with an electronic label, والتي سيتم استخدامها كتسمية موقع. And each identification card number is stored, the ID number in the location label is stored to identify the shelf number, and the ID number of the label is read by the staff holding the RFID handset, and the background system database can be called to obtain the storage information and information therein. بما فيها: نوع, اسم, نموذج, وحدة, سعر الوحدة, تاريخ الإنتاج, مدة الصلاحية, أداء, إلخ. من البند;
During the transfer operation, يحمل موظفي الجهاز RFID المحمولة, and the system sends the transfer instruction to the mobile data collector. The transfer personnel finds the specified location, takes the specified quantity of goods from the location, وتنقل البضائع إلى المستودع. The destination location, يتم إرسال البضاعة إلى الموقع, the contents of the shelf label are modified, and the transfer operation information is sent back to the background system.
When the warehouse management operation is performed, the label number is read to determine whether the current job location is correct. بالإضافة الى, as long as the ID number of a certain shelf is input, the related information of the ID can be retrieved from the background database, thereby realizing the material storage function.
The goods out of the warehouse and the warehousing are the same process. The same is the door to the warehousing. الجهاز RFID القراءة يمكن إعادة استخدامها. The RFID reading device scans all the cargo information of the library, and uploads the cargo information to the background system in real time. Outbound operation of the goods.
3.2 System framework
The RFID-based warehouse management system introduces RFID technology into the existing warehouse management, and automatically collects data for each operation link such as warehouse inbound, الصادرة, تحويل, and inventory counting to ensure data in all aspects of warehouse management. The speed and accuracy of the input ensure that the company can accurately grasp the real data of the inventory in a timely and accurate manner and reasonably maintain and control the enterprise inventory.
3.3 Operation process
3.3.1 Label Initialization
The link is to initialize the card for the goods label and the location label, encode the goods label and the location label according to the enterprise material coding rules, and use the RFID label printer to write the encoded information into the electronic label, وإذا تحتاج المعلومات التي سيتم طباعتها, في نفس الوقت, data such as library coded text or bar code information can be printed on the label.
Once the label is encoded and written, follow the label installation instructions to install the label on the goods and locations.
3.3.2 Outbound and inbound
After the goods are loaded with the goods label, they will be put into the warehouse through the storage port. An RFID reading device is deployed at the storage port to read the cargo label.
The RFID reading device will read the label information on all the goods in the warehouse in batches, وتحميل المعلومات التسمية إلى نظام الخلفية, and the background system will complete the storage operation of the goods corresponding to the label information.
After entering the warehouse, the RFID handset will be used to complete the binding of the cargo information and the storage position information. After the warehouse personnel put the goods on the cargo space, they read the cargo space label and the cargo label, استكمال الربط من اثنين, and upload the binding information to the background, والانتهاء من عملية التخزين بالكامل.
The outbound warehouse is the reverse operation process. The goods are cleaned out from the cargo space and executed out of the warehouse. When the RFID reading device is accessed through the outlet, the label information of all the goods will be read and the information will be uploaded to the background. The management system, the background management system will perform the check of the information and the outbound order information, and the correct upgrade will be able to exit the warehouse normally and complete the outbound process of the goods.
3.3.3 Transfer library
When the delivery of a batch of goods is nearing completion, عندما لم يكن هناك الكثير من الأوراق المالية, or when the next batch of bulk goods storage notice is received, it is necessary to transfer the warehouse and free up the storage space for new goods. At this time, يتم تنفيذ عملية النقل باستخدام الهاتف RFID.
The RFID handset step is to read the location label of the location of the goods that need to be transferred, ومن ثم نقل البضائع إلى الموقع المستهدف, and then use the RFID handset to read the location label of the new location, and the background system automatically performs the new label.
