OUTSIDE REARVIEW MIRROR PANORAMIC CAMERA POSITION ON THE AERODYNAMIC CHARACTERISTICS OF IMPACT STUDY by TONG GaoPeng, GAN Wei, LI ZhiWei, LIN Hui, WANG ZhiFeng

“…In order to reduce the influence of the panorama camera on the aerodynamic noise of the vehicle,the exterior flow field and sound field analysis are carried out on the rearview mirror of three different lens placement positions.The calculated results are in good agreement with the experimental data,which verifies the reliability of the numerical simulation.At the same time,it is found that the different position of the panoramic lens has an influence on the air flow which through the exterior mirrors,thus changing the rear flow field and the front window noise radiation intensity.Scheme Ⅲ is compared with other schemes,the tail vortex,the turbulence kinetic energy and the noise emission of the front window are relatively weaker,which can reduce the aerodynamic noise.Finally,by comparing the noise test of three kinds of schemes,it is found that the noise of scheme Ⅲ is lower than that of other schemes,which verifies the correctness of the analysis method.The analysis results provides the guidance for the reasonable arrangement of the rearview mirror panorama image lens,and is favorable for improving the comfort of the driver.…”

Intelligent operation and maintenance of power communication network based on data perception fusion by Huahui LYU, Zhe MING, Kai FAN, Qingming CHEN, Hongyu SHI, Wenjing ZOU, Dingbo WANG, Shengtao GUAN, Yong WU

“…Under the common influence of multiple factors and structural complexity in the power communication network, traditional operation and maintenance methods are vulnerable to the disturbance of abnormal voltage signal and abnormal transformer signal in the perception process, resulting in the global perception of the network and seriously affecting the overall operation and maintenance effect.In order to effectively solve the problem of perception bias caused by multiple factors, the data perception fusion algorithm was used to optimize the perception of the power parameters under the power communication network, so as to realize the effect of improving the perception accuracy and optimizing the overall quality of operation and maintenance.In the optimization scheme, the situational awareness scope of power communication network security was determined firstly.Secondly, the situational awareness of voltage security under power communication network operation was optimized.Thirdly, the security situational awareness parameters of power network transformer were defined based on the data perception fusion algorithm.Finally, the data perception fusion calculation of perception information was completed.The simulation comparison test shows that the data perception fusion algorithm has the ability to improve the overall quality of operation and maintenance, reduce the perception deviation in the process of operation and maintenance, and improve the perception sensitivity and accuracy.…”
