Digital association and high precision positioning and tracking system for multimodal transport container

A digital association and high precision positioning and tracking system for multimodal transport container, comprising a carrier terminal, a container terminal, and a remote digital monitoring platform;

• the carrier terminal is activated when a container is in an associated state, which is used to realize the matching of the container and the carrier, the collection of first positioning information of the container and other status information, and the transmission of the collected information to the remote digital monitoring platform;
• the container terminal is activated when the container is in a non-associated state, which is used to match the container and the carrier, collect the container status information, and send the matching result and collected information to the remote digital monitoring platform, wherein when the container enters signal transmission range of the carrier, a key matching is performed, if the key matching is successful, the container is set to the associated state, if the key matching is unsuccessful, the carrier and the container are unbound, the container is set to the non-associated state;
• the remote digital monitoring platform is used to send instructions to control the association and unbinding of the carrier and the container, and set the associated state or the non-associated state according to the matching result returned by the container;
• the remote digital monitoring platform also records and displays the identification information and status information of the carrier and the container according to the received information, and monitors the status of the container.
