SHIPPING CONTAINER VENT COVER FOR THEFT DETECTION, THEFT PREVENTION AND LOGISTICS MANAGEMENT AND METHOD FOR SECURING A SHIPPING CONTAINER

摘要

A vent cover (16) for installing on a shipping container. The vent cover includes a housing (16a) adapted for covering a vent hole (24) of the shipping container. A direct current (DC) power source is encased or enclosed in the housing. The DC power source includes a battery. The vent cover may also include a circuit board (34) attached to the DC power source. An antenna (36) may be located on a surface of the housing and attached to the circuit board. The circuit board may include a satellite antenna interface for a satellite antenna and a global positioning system (GPS) module attached to the satellite antenna interface. The vent cover may include an environmental sensor (304) for sensing a parameter of the shipping container. The environmental sensor may be adapted to protrude through a hole in a wall (12) of the shipping container when the vent cover is mounted on the shipping container. The electromagnetic sensor may be configured to transmit an electromagnetic signal (324) and sense an electromagnetic response signal (322) responsive to the transmitted wave and sensitive to variations within the container.
