The invention discloses an unmanned aerial vehicle tracking method based on an embedded platform. The problem that an occluded vehicle tracked by an unmanned aerial vehicle is lost in the prior art is solved. The method comprises the steps that 1 a vehicle classifier is trained and a map is marked; 2 an image is acquired, and a tracked target is initialized; 3 an image is acquired for target tracking; 4 the classifier is used to determine whether the target is occluded, and if so, the step 5 is carried out, otherwise the step 8 is carried out; 5 whether the target is in an occluded area of the map is determined, and if so, the step 6 is carried out, otherwise the step 7 is carried out; 6 target detection is carried out in the occluded area; the unmanned aerial vehicle hovers; and the step 9 is carried out; 7 the target location is predicted; 8 according to the target, the flight of the unmanned aerial vehicle is controlled; 9 whether the step is end is determined, and if so, tracking is ended, otherwise the step 3 is back. According to the invention, the occluded target can be detected and tracked; the tracking robustness is improved; and the method can be used to track vehicles on urban roads.

Biasing and scheduling transmission of data for access point transceivers. A transmission period of the transceivers is biased in adjacent cells into a plurality of time slots such that the biasing reduces interference among adjacent cells. The transceivers are then scheduled to transmit data packets during a selected time slot of the plurality of time slots that is distinct from each other.

The invention discloses a method and device for sending an enhanced physical downlink control channel. The method includes: determining the starting position of the ePDCCH in a subframe according to high-level signaling and / or preset rules; sending the pilot frequency and bearer of the ePDCCH Data on ePDCCH. Through the present invention, the interference between the ePDCCH and the downlink control channel is reduced, and the efficiency of downlink transmission is improved.

The invention discloses a wireless Internet of Things system and method for monitoring and regulating the humidity of corrugated paper transportation, including: an acquisition module collects water absorption humidity parameters of corrugated paper, video images of corrugated paper, stacking serial numbers of corrugated paper, and car space environment parameters; a wireless Internet of Things transceiver receives and The corrugated paper water absorption humidity parameter, the corrugated paper video image, the corrugated paper stacking number and the compartment space environment parameters are transmitted to the corrugated paper transportation control module; the corrugated paper transportation control module is based on the corrugated paper water absorption humidity parameter, the corrugated paper video The screen, the serial number of the stack of corrugated paper and the environmental parameters of the carriage space generate a control instruction; the carriage adjustment equipment group adjusts the environmental parameters of the carriage space of the target corrugated paper stack according to the control instruction. The system can comprehensively and accurately reflect the moisture content of corrugated paper in the transport compartment, and then regulate the equipment in the compartment according to the moisture content of the corrugated paper.
