Journal of System Simulation
Aiming at the requirement of autonomously tracking land moving targets of rotary-wing UAVs, an autonomous and stable UAV tracking and control system that can adapt to the common interference environments such as scale changes, occlusions, and attitude changes is constructed.The system extracts the imaging position of the target in airborne camera through the twin network based on deep learning, and obtains the relative pose of the target. The image processing algorithm is designed to process the icons in the tracking frame, and the yaw angle of UAV relative to the tracking target is obtained, Kalman filter is introduced to …

Distributed Power Emergency Rescue Perception And Cooperative Information Interaction Technology, Xiaojun Xie, Hanchen Lu, Ruoxin Shi
Journal of System Simulation
Abstract: An emergency rescue technology for modern vehicle was proposed based on the implementation process of positioning, communication and task. The key subsystems of information processing and multi-link message in the rescue system were developed. The cooperative interaction method and technical scheme of emergency command system were based on multi-link communication. To improve the communication effectiveness between the emergency command center and emergency rescue vehicles under harsh conditions, the problems of short message communication and vehicle data transmission were solved by establishing a framework for directing side and the vehicle side. Design and implementation of the system through the field …

Application Of Multiple-Stepwise And Kalman Filtering In Haze Forecast, Yunhao Xian, Hengde Zhang, Yonghua Xie, Le Yang
Journal of System Simulation
Abstract: Considering the importance of objective haze forecast and the low accuracy rate of haze forecast, a new haze objective forecast correction method based on the multiple stepwise regression algorithms and the Kalman filtering algorithm is proposed. The multiple stepwise regression method is used to control the physical factor of the dependent variable, and the visibility forecast equation is established. The Kalman filtering method is adopted to correct the regression coefficient in multivariate stepwise regression algorithm according to the actual data, and the haze objective forecast correction model is established. The experiments are carried out in Beijing, Guangzhou, Nanjing and …
