Marine container monitoring method based on Beidou navigation and wireless communication

The invention discloses a marine container monitoring method based on Beidou navigation and wireless communication, and relates to the technical field of container safety transportation. The monitoring method comprises the following steps of installing a plurality of sensors in a container for monitoring according to the requirements, collecting multiple container data to a relay node through a wireless communication technology, and collecting positions and states of cargos within the hull range through the relay node; making the relay node judge the position and safety information of the container, if an abnormity exists, sending the abnormal information; and transmitting the information to a carrier or a user in real time through short message communication and positioning functions of anetwork platform or a Beidou system. The method adopts the Beidou system, when a marine navigation communication condition is poor, key information transmission can be still carried out through Beidou short messages; and the
