Abrégé
(EN)
The invention provides a multisensor time synchronization method for unmanned plane power patrol and a system thereof. A GPS absolute time signal is obtained by integrating a local clock crystal oscillator signal and a GPS time signal. Then, operation trigger pulse of multisensors is detected by the utilization of the GPS absolute time signal so as to obtain absolute GPS absolute time of each operation of the sensors. Difference of sensor motion positions during the power patrol process of an unmanned plane is fully considered, and synchronous compensation time of the sensor motion positions is calculated so as to realize multisensory time synchronization. During the whole process, the absolute GPS absolute time of each operation of sensors of different types can be obtained simply. In addition, the difference in time synchronization caused by the position difference is fully considered, and time coordinate for motions of each sensor is measured accurately so as to realize multisensor time synchronization.
