RFID warehouse logistics management system adopts RFID automatic identification technology, and installs electronic labels on the goods and cargo positions of the warehouse, giving each goods and cargo position an identification, or marking on the pallet to associate the goods and cargo positions; Realize the rapid identification, automatic, efficient and batch collection of key operation links such as warehousing, warehousing, warehouse transfer, inventory and transportation in warehouse management.

UHF antenna and RFID reader are installed at the entrance of the warehouse. When the goods pass through the gate, the RFID reader is activated by cutting infrared rays, and the RFID tag will be read by the reader, so that the number of goods entering and leaving the warehouse can be known by counting the number of tags, and then the warehousing software automatically handles the entry and exit of the warehouse to complete the automatic entry and exit operation.

The inventory process is completed by using RFID handset. Workers can use RFID handset to read the data on the goods to be inventoried, at the same time, they can know the relevant information of the goods by reading RFID electronic tags, and they can also input the name of the goods to find the position of the goods in the warehouse.

Installing RFID tags on the shelves to identify the shelves, and installing RFID readers and on-board computers on forklifts can realize the association between goods and shelves; Reading the labels of shelves and goods by forklift reader can not only accurately record the storage location of goods, but also provide the location information of forklifts in the warehouse so as to allocate forklifts (please refer to the relevant scheme for forklift modification).

Features of adopting RFID radio frequency technology:

1, automatic storage: the reading and writing distance of handheld readers can reach 2-5 meters, and the reading and writing distance of fixed readers can reach more than 12 meters. It effectively solved the problem that barcode storage had to manually scan barcode in the past, realized automatic entry and exit, and greatly improved the labor cost of storage and the use efficiency of forklift.

2. It can instantly read dozens or hundreds of tags: once the tag enters the magnetic field, the RFID reader can instantly read the tag information; Using RFID anti-collision technology and UHF fixed reader, dozens of tags can be read instantly, which greatly improves the scanning efficiency and reduces the labor cost.

3. Reading without screen occlusion: When scanning a traditional bar code, the label cannot be occluded. RFID can penetrate non-metallic and non-liquid materials such as paper, wood, plastic, etc., and carry out penetrating communication without light source. Provide a better scanning experience, which can quickly tally, find and count goods. This is the warehouse management accelerator.

4. Large data capacity: the capacity of one-dimensional bar code is 50 bytes, the maximum capacity of two-dimensional bar code can store 2 to 3,000 characters, and the maximum capacity of RFID electronic tag is several megabytes. With the development of storage carriers, the data capacity is also expanding. In the future, the amount of data to be carried by articles will become larger and larger, and the demand for expanded capacity of labels will also increase accordingly.

5. Long service life, adapting to harsh environment: The radio communication mode of RFID enables it to be used in high pollution and high radiation environment such as dust and oil pollution, and its service life exceeds 10 year (65,438+million times of reading and writing); The carrier label paper of traditional bar code is easy to be polluted. In addition, because the bar code is attached to plastic bags or outer packaging cartons, it is particularly easy to be damaged; RFID tag stores data in the chip, so it can be free from pollution, and RFID has strong anti-pollution ability and durability.

6. Reuse: The content of RFID tags can be changed. The direct benefit is that RFID electronic tags can be reused, which can effectively reduce the cost of consumables for enterprises (enterprises that use barcode storage systems purchase a large number of tags and carbon tapes every year).

7. Security: RFID electronic tags can not only be embedded or attached to products of different shapes and types, but also can be password-protected to read and write tag data, which is more secure; Because RFID carries electronic information, its data content can be protected by password, so that its content is not easy to be forged and fabricated, and its security is higher.

8. Miniaturization of volume and diversification of shapes: RFID does not need to match the fixed size and printing quality of paper for reading accuracy, but is more suitable for miniaturization and diversification, so as to be embedded or attached to products with different shapes and types.

Scheme characteristics

Automatic identification of bulk goods

The RFID handheld terminal is used to bind RFID and commodities on site, which saves the printing time of RFID labels and the time of manually matching labels with commodities, and greatly improves the efficiency of commodity identification.

1. After the goods arrive, paste the RFID tag prepared in advance on the goods (there is no need to check whether the RFID tag corresponds to the goods);

2. After all the goods are labeled, select the product number, specifications and other information of the goods in the handheld RFID reader;

3. Use the handheld RFID reader to scan the goods with tags, and the system automatically associates RFID tags with goods in batches, and the goods identification is completed.

RFID location

The RFID tag is used to identify the warehouse location, and the RFID tag number read by the wireless PC and RFID reader on the forklift can ensure that the goods are placed in the correct location. Generally, the metal-proof RFID tag is selected as the location tag.

Ultra-high scanning speed

Barrier-free reading, scanning dozens of labels at the same time, a brand-new scanning method, greatly improving storage efficiency and reducing storage costs.

Storage advantage

The storage capacity of tags is large, and some tags can store several meters of data. Even though ordinary RFID tags can store hundreds of K data, and the tag size is not affected by the size of the stored data, enough cargo information can be stored in the tag.

reuse

The service life of RFID tags is generally more than 10 years (65438+ millions of reads and writes), and the content can be changed, so RFID tags can be reused, reducing the storage cost of enterprises.

Improve the utilization rate of forklift trucks

Add RFID reader and on-board computer on forklift to realize the correlation between goods and shelves; Reading the labels of shelves and goods by forklift reader can not only accurately record the storage location of goods, but also provide the location information of forklifts in the warehouse so as to allocate forklifts. The position and state of each forklift can be grasped in real time, the forklift scheduling is more flexible, and the forklift utilization rate is maximized.

Automatic storage

When there is a new warehouse receipt:

1. The system selects the idle forklift according to the forklift dispatching plan, and sends the warehousing instruction to the tablet computer of the forklift.

2. The forklift hand takes out the pallet according to the warehousing instruction received by the tablet computer, and the reader on the forklift reads the label information of the pallet and compares it with the information on the warehousing instruction to ensure that the operated goods are consistent with the received warehousing instruction.

3. The forklift passes through the RFID warehouse door, and the reader on the warehouse door reads the electronic tag on the forklift, opens Carmen after confirming the identity, and sends the read forklift information and pallet tag information to the background.

4. After the forklift arrives at the target cargo space, the reader reads the cargo space label, and after confirming that it is consistent with the target cargo space of the instruction, the goods are put on the shelves, and the instruction is transmitted back to the host system.

5. The host system confirms the warehousing, generates a document update database, and records the operation log.

Automatic outbound

When there is a new outbound order:

1. The host system selects the idle forklift near the warehouse to be delivered and sends delivery instructions to the tablet computer of the forklift.

2. After the forklift reaches the target position according to the pallet details on the tablet computer, the reader reads the position and the pallet label and compares it with the delivery instruction. After confirmation, the pallet goods are removed from the shelf. If only part of the pallet goods are taken away, the target pallet needs to be selected manually.

3. After picking up the goods, send instructions to the host system to complete the delivery.

4. After all the goods are picked up, use RFID mobile phone to scan all the pallet labels, check them with the delivery list information, restore the pallet labels, and send instructions to the host system after they are correct.

5. The host system confirms the delivery, generates documents to update the database, and records the operation log.

6. After all the list details are put into storage, collect data and check the list data, and send the check result to the customs supervision platform system.

Ultra-efficient inventory

Using RFID multi-label inventory function, the warehouse inventory can be counted quickly, which greatly improves the problem of long time-consuming inventory scanning in barcode mode.

security detection

When the goods are delivered out of the warehouse, the system will automatically judge. If they are not delivered out of the warehouse (goods specified in the delivery order), the system will automatically give an alarm to prevent the goods from being stolen.

Implementation benefit

Inventory availability increased by 5% to 10%.

The delivery speed has increased by 10%
