RFID Solution in container

In recent years, container transportation has become an important form of transportation modernization due to its high efficiency, convenience and safety. With the rapid development of my country's economy, the port is an important node in my country's modern logistics and supply chain, and the container handling capacity continues to grow. Therefore, the level of container management and informatization has become the key to restricting container transportation.

In order to improve the management level and information level of container transportation, the "container electronic label system" was born in many studies and experiments, and was the first to be applied and demonstrated in my country's domestic container transportation. The release and promotion of the container electronic label system will help accelerate the development of low-cost, safe, reliable, and easy-to-use container electronic devices, and will play a positive role in improving the level of international container safe transportation.

Application significance of container electronic label system

The container electronic label system, through the organic combination of radio frequency identification technology and the Internet, provides logistics and commercial enterprises with real-time status information of containers.

Its existence has very typical industry characteristics. First of all, the operating environment of the container electronic label system is relatively complex and technically difficult in the electronic label application field. The technical indicators, process indicators, and functional requirements are far different from other fields; second, the container electronic label is the application In a huge logistics network environment, the network involves the participation and cooperation of many countries, regions and departments, especially involving the application promotion of many departments and units, which will be very critical; third, as mentioned above , The comprehensive application of container electronic tags will surely produce huge benefits to the logistics industry: effectively improve management and production and work efficiency, ensure the safety and quality of cargo transportation, and produce huge benefits.

Current status of container electronic label system

At present, the system has been applied on many international routes such as China-US, China-Japan, China-Canada, China-Malaysia. The container RFID freight label system is a publicly available standard proposed by China and actively promoted by China and officially released by ISO.

Electronic label coding and authorization

The electronic label storage information content is divided into 2 parts and 5 areas:

Part 1 is divided into 4 areas to store 4 types of information: ①Fixed information (A area) includes serial number, box number, holder, box type, and size; ②Goods information (B area) includes waybill number and seal number , Port of departure, port of destination, cargo name, box weight, number of packages, special requirements for the cargo; ③Other information (zone C) includes the record of the port of departure, the record of the transshipment port, the transport record of the transshipment container site, the port of destination record, the container of the destination port Site hoisting records, mechanical ID numbers and damage records; ④The electronic seal information (zone D) includes the date of unpacking, the time of unpacking (hour, minute, second) and the cumulative number of unpacking.

The second part stores freight forwarding information (zone E), and records the relevant content of the cargo consignment letter.

Authorization for reading and writing electronic tags in each link According to the characteristics of container transportation, certain authorization settings are given to reading and writing electronic tags in each link, including information such as freight forwarding, port of departure (entry), damaged records and automatic writing of electronic seals.

The electronic label code adopts the basic structure of the Global Trade Number (GTIN).

Main content and features

The container electronic tag is an automatic identification device with microwave two-way communication function. It is attached to the container and serves as the container's information carrier and safety certification device.

1) Container electronic label information entry equipment: portable computers and handheld PDA readers are mainly used to enter container information.

The handheld PDA reader is used to complete the writing, reading, verification or information exchange of electronic tags at the source of freight, port crossings, yards, shores, shipping and other container operations.

2) Container electronic tag base station reader: used in fixed positions such as entrances and exits. It exchanges data with the electronic tag by means of wireless communication, collects and updates the information in the tag, and communicates with the computer through RS232/485.

3) Container electronic tag wireless reader: installed on mobile devices such as gantry cranes, bridge cranes, gantry cranes, reach stackers, etc., to exchange data with the container electronic tags by means of wireless communication to collect and update the information in the tags , And communicate with the computer wirelessly through the container electronic tag wireless bridge.

4) Container electronic tag wireless bridge: a wireless communication device used to replace "tag reader communication cable".

5) Container electronic tag sentry: used in yards, bridge cranes, gantry cranes, gantry cranes, forklifts, etc., to cooperate with wireless readers to complete automatic identification of the uniqueness of container electronic tags.

6) Electronic container seals: Electronic container seals are equipment used to ensure the safety of containers.

The basic principle of RFID technology is electromagnetic theory. The advantage of the radio frequency system is that it is not limited to the line of sight, and the recognition distance is farther than the optical system. The radio frequency identification card can read and write, can carry a large amount of data, is difficult to forge, and is intelligent. It is suitable for occasions that require non-contact data collection and exchange such as container tracking and vehicle identification. Due to the readable and writable ability of RFID tags, it is especially suitable for occasions where data content needs to be frequently changed.
