Abstract
Provided are a device and a method for tracking air cargo that determine whether air cargo is loaded on the basis of sensing values of a pressure sensor and an accelerometer, and switch to a flight mode when the loading is completed to block communication with an external device. The provided device for tracking air cargo detects acceleration information and pressure information according to the movement of the air cargo, generates tracking information of the air cargo on the acceleration information and the pressure information, transmits the tracking information to an external device, and switches to a flight mode on the basis of one of the acceleration information, the pressure information, and whether a communication signal is received.
Claims20
A device for tracking air cargo comprising:
- a sensor unit configured to sense acceleration information and pressure information based on a movement of air cargo;
- a tracking unit configured to generate tracking information of the air cargo based on the information sensed by the sensor unit;
- and
- a communication unit configured to transmit, to an external device, the tracking information generated by the tracking unit,
- wherein the tracking unit stops the communication unit by changing its mode into a flight mode based on one of the information sensed by the sensor unit and whether the communication unit receives a signal.
A method of tracking air cargo by using a device for tracking air cargo, comprising steps of:
- tracking an indoor movement, outdoor movement, and up and down movement of air cargo based on acceleration information and pressure information based on a movement of the air cargo;
- determining whether the air cargo is loaded onto an airplane based on tracking information in the tracking step;
- determining whether a door of a cargo compartment has been opened or closed based on one of whether a communication signal has been received and a change in a quantity of light when determining the loading to be loading of the air cargo onto the airplane in the step of determining whether the air cargo is loaded;
- and
- changing a mode into a flight mode when determining a state of the door of the cargo compartment to be a closed state in the step of determining whether the door of the cargo compartment has been opened or closed.
