Technical Field
With the globalization of economy, the rapid circulation of commodities is continuously stimulated and accelerates the rapid development of the logistics industry. The logistics industry is a composite industry formed by industrialized logistics resources, and is an indispensable important link of the logistics industry, the warehousing faces higher and higher industry requirements, and the management level and the early warning level in the warehousing link are effectively improved. The basis of warehouse management is cargo management, the currently applied cargo management mode combines a manual checking mode through a bar code, and warehouse cargo entering and exiting warehouse management is carried out through scanning the bar code, so that the management of the quantity and the type of the cargo entering and exiting the warehouse is not accurate, the efficiency is low, the derived errors are numerous, the real-time performance is poor, the automation degree is not high, and the real-time condition and the quantity of the cargo in the warehouse can not be accurately grasped. Therefore, the using efficiency and the intelligence of the warehousing system are effectively improved, and the realization of effective management of warehoused goods has important significance for the development of the logistics industry.

A warehousing goods management method based on CSS micro base stations and RFID is characterized by comprising the following steps:
step 1: before goods are put in storage, the system performs storage preparation, and when goods required to be put in storage reach the PC, an operator inquires related information (such as name, quantity, supplier code and the like) of the goods on the PC according to information of the storage list;
step 2, after the goods formally enter the storage area, reading label ID information pasted on the goods by a reader-writer, forwarding the label ID to an upper computer by user terminal equipment, inquiring the goods information corresponding to the read label ID through a background database system, comparing the goods information with information of a warehousing entry, and reminding warehouse personnel to check when errors are found;
and 3, the user terminal equipment simultaneously communicates with the CSS micro base station, the accurate positioning of indoor goods is realized through map matching of the storage area, and the CSS micro base station can realize the positioning error with the precision within 1 meter in the trilateral positioning. The user terminal equipment sends the acquired cargo position information to an upper computer and stores the cargo position information in a background database system;
and 4, step 4: when the goods are subjected to the plate inspection and sorting, the residual quantity of the current goods is checked and known in real time by scanning the ID information of the tags on the goods, and the position information of the sorted goods is updated to remind a warehouse manager of the utilization condition of the current warehouse;
and 5: when goods are delivered out of a warehouse, according to goods lists needing to be delivered out of the warehouse, the position information of the goods needing to be delivered out of the warehouse is inquired through a background database system, position navigation is rapidly achieved through communication between user terminal equipment and a CSS micro base station, warehouse management personnel are guided to search target goods, after delivery out of the warehouse is completed, goods ID information is scanned, the number and names of the goods delivered out of the warehouse are inquired in time and updated, and the warehouse management personnel can master the current goods information.
Compared with the prior art, the warehousing goods management device and method based on the CSS micro base station and the RFID, provided by the invention, have the advantages that the identification and management of warehousing goods are realized through the RFID technology, the position determination of the goods is realized through the CSS micro base station, the goods are convenient to search and inventory, the controllability of the warehouse goods in the warehousing-in and warehousing-out process is ensured, the manual input is not needed, the warehousing management efficiency of the goods is effectively improved, the method is simple in structure and easy to realize, and a foundation is provided for the effective use of a large warehouse.
Detailed Description
In order to facilitate further cognition and understanding of the characteristics and functions of the invention, the structure of the accompanying drawings is described in detail below, and fig. 1 is a schematic structural diagram of a warehouse cargo management method based on CSS micro base stations and RFID of the invention, the system includes an upper computer and a background database system, CSS micro base stations, user terminal equipment, RFID tags, an RFID read-write module, and a network coordinator; the RFID read-write module is integrated with the user terminal equipment, and the network coordinator is connected with the upper computer through the serial port to achieve data uploading. The CSS micro base station is installed on a shelf of a warehouse, the RFID tag is adhered to the goods put in the warehouse, and the RFID reader-writer and the user terminal device are integrated together to realize data reading of the tag and goods positioning.
The embodiment of the invention has the following applicable flows: when goods need to be put in storage, the system carries out storage preparation, including initialization of the reader-writer and initialization of the PC, and preparation for detecting the goods is made. When the goods required to be put in a warehouse reach the PC, an operator inquires related information (such as name, quantity, supplier code and the like) of the goods on the PC controller according to the information of the warehousing order, then scans the RFID tags on the goods in the warehouse by using an RFID reader-writer, simultaneously, the user terminal equipment communicates with a CSS micro base station arranged on a goods shelf through a three-edge positioning mode to realize the position determination of the goods, uploads the ID information and the position information to the PC through the user terminal equipment and a network coordinator, and checks whether the items of the goods order are consistent with the actual goods on the PC and stores the position information of the goods. If the data on the delivery receipt is not met, the system directly gives an alarm, and the warehouse operator refuses to receive the delivery; if the document is matched with the document in the warehouse, the system gives corresponding information.
When warehouse management personnel carry out pallet inspection and sorting, the goods are sorted according to the storage position placing condition of the warehouse, the stacking types can be point stacking, batch stacking, classified stacking, stacking according to different manufacturers, matched stacking and the like, at the moment, the label ID information on the sorted goods is scanned, the remaining quantity of the current goods is checked and known in real time, the position information of the sorted goods is updated, and the warehouse management personnel are reminded of the utilization condition of the current warehouse;
when goods need to be delivered from the warehouse, an operator inputs related information in the PC according to the delivery order, the goods and the position which accord with the delivery certificate are inquired through the database system, the position navigation is rapidly realized through the communication between the user terminal equipment and the CSS micro base station, the warehouse manager is guided to search the target goods, and the delivery list which accords with the requirement is generated and contains the related information of the goods, such as the material receiving order number, the delivery position, the code, the box number, the destination, the whole packaging quantity and the like.
When the delivery is finished, the operator performs delivery inspection to confirm whether the picked goods are consistent with the material receiving list or the delivery notice list, the confirmation of delivery is finished, after the verification is finished, the read label information is uploaded to the database through the RFID reader-writer, the delivery confirmation is finished in the database, and the delivery list is printed.
