In recent years, electronic labels have been applied in some practical applications, such as process industry logistics management, air package management, terminal container management. At present, the source of the container is the box of the container leasing company except the actual carrier's box, the non-vessel carrier's part of the box and the owner's own box. The actual carrier can be the ship company, the owner of the train, the car, the plane, and they control these means of transport. The non-vessel carrier is in the container transportation, operating cargo container cargo, packing, unpacking, inland transportation and business transfer or inland warfare operations, but does not operate ships. There are three main ways for shipping companies to operate containers in China's shipping market:

1) Large shipping companies with strong domestic strength usually set up a container management department within the company, which is responsible for the recycling and management of containers. For the related business of container recycling and management, the container management department of the shipping company establishes the corresponding legal relationship in the name of the shipping company, signing the container equipment handover list and collecting the pressure box fee in the name of the shipping company itself.

2) Large shipping companies with strong foreign powers usually set up shipping branches in major ports in mainland China, and set up container management departments within shipping branches, which are responsible for container recycling and management. For the related business of container recycling and management, the container management department of the shipping branch establishes the corresponding legal relationship in the name of the shipping branch, signing the container equipment handover list and collecting the pressure box fee in the name of the shipping branch. The shipping branch actually acts as the operator and manager of the container of the foreign shipping company in China.

3) Some of the smaller shipping companies in China or some of the smaller foreign shipping companies that do not have a shipping branch in China usually sign a container management agreement with a domestic shipping or shipping agency to entrust domestic shipping or shipping agents. Companies and other units are responsible for the recycling and management of containers within China. For the related business of container recycling and management, the container management department of domestic shipping or shipping agency companies establishes corresponding legal relations in the name of domestic shipping or shipping agency companies, in the name of domestic shipping or shipping agency companies. Sign the container equipment handover list, collect the pressure box fee and so on. Domestic shipping or shipping agency companies also act as operators and managers of these shipping companies in China.

If, according to the theoretical container transfer method, each responsible part of the circulation complies with the original rules, the container can be recovered in time, but in fact, it is not as we wish, the container recycling is not timely, and the container damage is present. . For example, if the delivery method is CY-CY, it is from the carrier's container yard at the loading port to the carrier's container yard at the port of discharge. If strictly in accordance with this regulation, the carrier should unpack the container at the container yard of the port of unloading, take the goods from the container, and then deliver the goods to the consignee or its entrusted agent.

But in fact, because the carrier's container yard and the consignee's warehouse often have a long distance, if you completely mechanically do the above-mentioned operation method, it will inevitably add a lot of inconvenience to the consignee. According to the maritime customary practice, the carrier or the operator or the manager of the container entrusted by the carrier usually delivers the complete container filled with the goods to the consignee or its entrusted agent, and the carrier or the container it entrusts to operate. The person or manager also gives the consignee or his entrusted agent a free period of use of the container for a few days. The consignee or his entrusted agent then transports the goods to the consignee’s warehouse, but the carrier or the operator or the manager of the entrusted container in order to ensure that the container returns on time, the premise that the suitcase must deliver the press box fee And issue a list of container equipment handovers, specifying the free period of use and the location of the return box. Sometimes the shipper does not return the container to the designated place on time, which causes a lot of inconvenience.

The use of electronic labels on containers means that the electronic label system is an important carrier for the electronicization of container information. The detailed information such as the container number, manufacturer, owner, etc. is entered into the electronic label. When the labeled container passes the reader, the label The product data is passed to the reader, which then downloads the data to the central processor to generate a container management database. In this way, all the processes from the factory to the final unloading of the container can be clearly understood and grasped, so that the container circulation is smoother, which can help the container recycling department to keep abreast of the dynamics of the container and keep in touch with the owner or agent or the renter. The contact method can be fax or network to avoid being abandoned due to being left unattended for a long time, effectively improving the utilization rate of the container. If the labels of several containers are issued at the same frequency as the target object, there may be conflicts, so there is anti-collision technology. Therefore, in order to obtain accurate and timely information about the container, other basic technologies including database technology, electronic data interchange (EDI) technology and network technology are needed.
