The working principle of RFID technology

RFID technology utilizes radio frequency signals for data transmission, mainly composed of three parts: tags, readers and data processing systems. The tag is usually attached to the container and contains unique identification information. The reader is responsible for reading the information in the tag and transmitting it to the data processing system for analysis and storage.

In the intermodal transportation of containers in ports, RFID tags are scanned by readers when the containers enter and leave the port. Through real-time collection of container location, status and transportation information, the management system can quickly and accurately grasp the dynamics of the container. This process greatly reduces the need for manual operation and improves the accuracy and real-time data.

Advantages of RFID technology

Real-time: compared with the traditional bar code, RFID technology can realize non-contact recognition, do not need to align the scanner. Therefore, the status update of the container during transportation can be done in real time, which greatly improves the timeliness of the data.

High degree of automation: RFID systems enable automated cargo management and tracking, reducing manual intervention. This not only improves efficiency, but also reduces losses due to human error.

Data storage capacity: RFID tags can store more information, such as transportation routes, loading and unloading times, and cargo status. This rich data supports further analysis and decision-making, providing a more comprehensive perspective on container management.

Environmental adaptability: RFID technology has strong environmental adaptability and can work properly under harsh conditions (e.g. high temperature, high humidity, etc.). This is especially important in complex operating environments such as ports.

Reduced Costs: Although the initial investment in RFID systems is high, in the long run, the overall operating costs will be significantly reduced due to its improved efficiency and reduced error rate.

Application Cases

Taking a large international port as an example, the handling time of containers has been shortened by an average of 30% after the introduction of RFID technology in the port. Containers are automatically recorded through the RFID system when entering and leaving the port, and managers are able to grasp the location and status of the containers in real time. In addition, the port used RFID data for analysis to optimize transport routes and reduce waiting times.

Another case is a logistics company that uses RFID technology for container management in multimodal transportation, successfully realizing seamless connection with railroad and road transportation. Through real-time data sharing, the logistics company was able to anticipate potential transportation problems in advance so that it could quickly adjust its program to ensure that the goods were delivered on time.

Conclusion

In the context of the Internet of Things (IoT), RFID technology provides an innovative solution for multimodal transportation of containers in ports. By improving the real-time and accuracy of data, automated management processes and environmental adaptability, RFID technology effectively enhances the operational efficiency of ports and reduces costs. With the continuous progress of technology, the application of RFID in port container management will be more extensive in the future, opening up a new path for the intelligent development of global logistics.
