Description

Container RFID electronic label system

technical field

The utility model relates to an application method of an electronic label, and more specifically relates to an application method of a container radio frequency identification (Radio Frequency Identification, referred to as RFID) electronic label.

Background technique

Container automatic identification technology mainly includes three main forms: container number video automatic identification technology, bar code automatic identification technology and radio frequency (RFID) electronic tag automatic identification technology.

Container number video image automatic recognition technology is to use photography equipment installed in container ports, container terminal gates, transportation lines or roads to collect container video images, and realize automatic recognition and recording of container numbers through image processing and pattern recognition. Due to the impact of external environmental conditions and the degree of contamination of the container body in this way, the system has a high misrecognition rate, and the reliability and accuracy are not high enough.

The automatic barcode recognition technology collects barcode images through an optical recognition system and recognizes the barcode. The disadvantage of this technology is that the anti-fouling performance is poor, and it needs to be scrubbed frequently after being eroded by oil, sand, ice and snow, etc., and the reliability of reading cannot reach 99.99% specified in ISO 10374:1999.

Radio frequency identification technology has the characteristics of being able to identify multiple objects at the same time, readable and writable, strong penetrating power, long recognition distance, fast recognition speed, long service life, good adaptability to the environment, and high readability rate.

The RFID electronic tags fixed in the container are mainly used for container identification. Containers are the main transport carrier for the global circulation of goods, and the circulation chain involves yards, docks, ports, customs, transport ships, etc. In different occasions, the container hoisting equipment structures and hoisting methods may be different, and there are top hoisting and side hoisting methods. In order to achieve the minimum amount of electronic tags for each container and to adapt to all the hoisting equipment experienced in the entire life cycle of the container, special requirements are put forward for the installation position and quantity of electronic tags on the container and the installation position and quantity of antennas on the hoisting equipment . At present, there is no set of better container electronic label application solutions at home and abroad, such as:

A container electronic tag device disclosed in CN200420037164.3 utility model patent, including an electronic tag installed on the surface of the container body, a reader-writer integrated or separately installed on the running channel of the container or on the lifting equipment Through a non-contact way to identify container information and track and record container logistics information during transportation, it improves the work efficiency of container transportation and the identification of container information during transportation and the ability to read and write container logistics information Reliable and safe. However, when using as few electronic tag devices as possible and installing them randomly on the container body, it may not be able to adapt to different hoisting equipment, and it is difficult to meet the requirements of automatic identification in the entire life cycle of the container; therefore, this solution has not been solved from the entire container circulation chain How does the electronic label device apply to different hoisting equipment and operation directions, so as to fully meet the requirements of automatic information identification under the global circulation of containers.

The electronic tag device for transport carrier disclosed in CN200520019851.7 Utility Model Patent describes the structure and application method of an electronic tag for a transport carrier, but does not propose the permanent fixed installation position of the electronic tag on the container and the adaptation to all containers The number and arrangement of antennas for hoisting equipment.

The applicant’s previous patent application for a container door lintel equipped with an electronic tag and a container using the door lintel proposed installing an electronic tag on the container door lintel. It is difficult to install a suitable reader and antenna on the spreader of some container hoisting equipment to identify this tag.

Therefore, the existing container electronic label device needs to be further improved to achieve the purpose of adapting to all hoisting equipment experienced in the entire life cycle of the container, and the purpose of using the least amount of electronic labels for each container.
