RFID technology is expected to become a cornerstone of the development trend of smart logistics

Warehousing management has always played a very important role in the logistics process. As the logistics field has begun to adopt RFID technology, a huge amount of logistics goods are circulated every day. RFID technology has quickly eliminated traditional technology due to its fast speed and good stability. . The development of smart logistics is inseparable from the Internet of Things, RFID, picking and other technologies, and various technologies are gradually integrated into the Logistics industry. RFID technology is expected to become a cornerstone of the development trend of smart logistics!

Although most of them have begun to deploy RFID technology, logistics companies can obtain benefits such as shortening the operation process, increasing the throughput of distribution centers, improving the quality of inventory operations, increasing the transparency of supply chain management, and transmitting information more quickly, accurately, and securely. , but still needs to be optimized.

Because there are a variety of items transported in logistics, generally speaking, conductive liquid substances will have a strong absorption effect on electromagnetic waves, while metal objects or high-density non-metallic materials will have a reflection effect on electromagnetic waves. In logistics applications, especially in daily necessities, luggage sorting, etc., the contents of logistics objects are often uncertain. That is to say, the properties of logistics objects are very complex, ranging from solid to recyclable. conductive liquids and possibly metal objects.

The shape and size of objects. Shape of the object to be recognized For regular-shaped objects, it is easier to install labels without causing obstruction. The impact on the RFID recognition effect needs to be considered from various aspects. The size of the recognized object is directly related to the reading distance of the system and affects the installation method of the reader system. Of course, if the tag is fixedly installed on one side of the reader antenna, the reading effect can be guaranteed to be ideal.

The moving speed of the object. The speed of movement of the identified object is related to the time the tag stays in the electromagnetic field, which is the time it takes for the tag to obtain energy. The longer this time is, the more the internal capacitor of the tag is charged, and the longer the continuous discharge time is, the more stable and reliable the work is. However, with the gradual improvement of the performance of readers and antennas, the accuracy of reading results that will be affected by excessive speed will be effectively controlled.

Since the basic principle on which the RFID system works is the coupling and propagation of electromagnetic waves, the performance of the system is very sensitive to the electromagnetic influence of the installation environment. In actual applications, a wire, network cable, etc. in the installation environment may affect the reading performance of the system. In the logistics center, there may be various metal shelves, which will seriously affect the transmission of RFID electromagnetic waves.

The so-called application level of the RFID system refers to the level at which RFID tags are applied, whether it is the single product level, small packaging level, large packaging level, pallet level or container level, etc. Taking cigarettes as an example, its application can be for each pack of cigarettes, a carton, or a box. For warehouse management, it can also be a pallet. Applications at different levels will change the size of the recognized objects, the number of recognized objects recognized at the same time, etc., thus also affecting the quality of the recognition effect.

The shape, size and installation method of the label will also affect the stability of use. Labels come in various shapes, including bar-shaped, card-shaped, cylindrical and various special-shaped labels. The size and shape of the label need to be determined according to the needs of the specific application system. But the smaller the label, the worse the reading effect, and the more difficult it is to encapsulate the label. Label installation includes pasting, hanging, embedding, wearing, etc. For larger labels applied on trucks, containers, etc., riveting can also be used. The choice of installation method and installation location is also very important for the system.

For the entire RFID system, RFID electronic tags are consumables, so the cost of the tags is relatively high. Therefore, the selection of the RFID system must be based on the value of the identified item itself and the added value it can create. Let’s consider it comprehensively.

The application of RFID in the logistics field has become a certain contributor to the development trend of smart logistics. There are still many problems that need to be continuously optimized. The various advantages of RFID technology will work perfectly. As the technological innovation process of logistics enterprises accelerates, information management efficiency and transparency have become ideal goals. Continuously improve effective operating procedures and improve work efficiency to meet the future informatization, intelligence, and modernization of logistics.
