UHF RFID container management system based on RFID technology

1.Background

Containers are the main transportation equipment for international logistics. 90% of international freight is completed through container transportation. In 2006, global container throughput reached 421 million TEU, and container trade volume reached 117 million TEU. Containers have obvious advantages in transportation, mainly in ensuring the safety of goods, saving packaging costs, improving loading and unloading efficiency, and accelerating capital flow.

However, there are still many problems in the current container transportation management. This is mainly due to the traditional management model, where the staff manually record the location of each container, and then manually enter the data into the container management system. database to complete the binding of container data and actual storage data. Facing such a large-scale, international freight transport circulation carrier, the information collection, tracking and supervision of container numbers are mostly done manually or manually. Due to inaccurate identification of box numbers, errors in manual data transcription, delays in information transmission, etc., the entire container management is chaotic and cannot meet the requirements of modern Logistics Management.

2.Technical application

RFID is a "radio frequency identification" non-contact automatic identification technology that can realize automatic identification of stationary or moving objects and people. RFID technology automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various environments. It can identify high-speed moving objects and identify multiple targets at the same time. RFID technology can be used to locate and identify almost all physical objects, and is one of the important means of informatization in the identification field.

After development in recent years, RFID technology has been widely used in production, logistics, transportation, medical care, anti-counterfeiting, tracking, equipment and Asset MANAGEMENT and other application fields that require the collection and processing of data. It is considered to be the future replacement of barcode labels. Taste.

It is very meaningful to apply RFID technology to container management and use the advantages of RFID technology in the field of automatic identification to develop a container information management platform to greatly improve the efficiency and effectiveness of container transportation management.

3.Program design

The informatization level of the current container logistics process is one of the bottlenecks restricting the development of today's container transportation. Since the container itself does not carry information, during the transportation process, the flow and identification of the container can only rely on manual operations, which greatly affects the efficiency of transportation, loading and unloading, and management. For the global container supply chain, it is extremely important to accurately obtain the location and safety information of goods, realize supply chain transparency, optimize management, reduce the uncertainty of inventory and transportation cycles, and improve the efficiency and effectiveness of the supply chain. It is also a modern Logistics urgent needs.

The overall structure of the system is as follows:

By installing RFID electronic tags on the container, and installing RFID Readers and writers on each business process operation equipment, during business operations, the RFID readers and writers read the electronic tag data, obtain the container information, and then transmit it to the backend for centralized processing through the network. The system realizes tracking and management of the entire container, and implements real-time scientific dispatching and capacity allocation of container transportation equipment.

In the system, the core RFID data collection equipment will be installed in mechanical equipment such as gantry cranes, reach stackers and stackers. For applications on such equipment, in addition to basic data collection functions, RFID readers should also have The use standards of vehicle-mounted equipment have very high requirements for high and low temperature, electromagnetic compatibility, low-frequency vibration, impact, etc., and the working environment is mostly outdoors and the environmental conditions are relatively harsh, which puts forward higher requirements for the selection of the entire RFID reader. challenges.
