Electricity meter area identification technology based on channel coding theory by Yinghai XIE, Yu ZHANG

“…Station area identification has always been a problem in the ubiquitous power Internet of things, a new analytical model similar to fading channel was established for the station area identification, and based on the remote on-load voltage regulation function of on-load capacity and voltage regulation distribution transformer, the channel coding theory was applied to solve the problem.In order to identify station area of the smart meters, different special voltage regulation schemes with the properties of repeated coding and block coding were applied synchronously.At the same time, the power consumption information acquisition system was used to collect the voltage of each smart meter in this period.Finally, the recognition of each meter was realized based on the principle of minimum distance of decoding algorithm.The theoretical analysis and test results show that, compared with the traditional technology, the new technology can realize the high accuracy identification of a large number of meters in the on-load capacity and voltage regulation distribution transformer area in the existing power grid system without upgrading, which has high engineering application value.…”

FAULT DIAGNOSIS NEW METHOD OF ROLLING BEARING BASED ON ADAPTIVE REDUNDANT LIFTING SCHEME PACKET by XIAO ShunGen, SONG MengMeng, LAI LianFeng

“…Aiming at feature identification of weak signal for rolling bearing fault,an adaptive redundant lifting scheme packet（ ARLSP） diagnostic method of undecimated operation was proposed to solve the faults distortion that caused by traditional wavelet packet or lifting wavelet transform using sample operation.ARLSP was based on the principle of lifting scheme.Initial undecimated prediction and update operator were calculated by Lagrange interpolating subdivision,and then constructed an ARLSP decomposition and reconstruction algorithm.Simulation signals were tried out by denoising and anti frequency aliasing,results show that ARLSP method was superior to the traditional wavelet packet in denoising capabilities,and there are no frequency aliasing.Moreover,taking an experiment on an asynchronous motor,the vibration signals of the rolling bearings 6205 under conditions of no fault,the inner ring fault,outer ring fault and rolling fault were measured.ARLSP method has been successfully used to extract characteristic frequency and frequency multiplication for various faults,and has got a higher diagnostic accuracy than traditional wavelet packet.…”

DYNAMIC RELIABILITY ANALYSIS OF PHOTOVOLTAIC SUPPORT SYSTEM CONSIDERING MULTIPLE UNCERTAINTIES by ZHONG Wei, YANG HuanHong, MA XiangDong, HUANG LongAn

“…Dynamic reliability analysis method of photovoltaic support system(PSS)was proposed considering the multiple uncertainties.Firstly,the reliability analysis model of PSS was constructed based on the probability density evolution method(PDEM),including the probability conservation equation,basic governing equation and density evolution equation.Then,the finite element analysis model of PSS was built,including the structural stress model,load combination form,and mesh generation algorithm.In simulation,the randomness in load combination and structures were incorporated,in which consists of six basic random parameters and 44 representative systems.The solution efficiency was improved by the joint simulation of PDEM and Abaqus.Results show that stress and displacement are two failure modes of PSS,and the influence of the latter is more obvious.The reliability index under the basic load combination condition is 0.928.As wind speed increases,the structural reliability decreases.In the high⁃speed range larger than 40 m/s,the uncertainty in structure itself will overestimate the reliability level of PSS,which should be paid attention in design.…”

Certificateless ciphertext retrieval scheme with multi-user and multi-keyword based on cloud-edge collaboration by Xiaodong YANG, Tian TIAN, Jiaqi WANG, Meijuan LI, Caifen WANG

“…To solve the problems of single-user search, single-keyword search, high computational cost and low-security level of ciphertext data retrieval in the industrial Internet of things environment, a certificateless ciphertext retrieval scheme with multi-user and multi-keyword based on cloud-edge collaboration was proposed.A user access permissions table was set and once encryption algorithm was executed to realize multi-user search and update users’ access permissions.A cloud-side collaborative computing model was introduced to match keyword ciphertext and keyword trapdoor efficiently by a linear scanning method when the keyword ciphertext does not entirely contain the search keyword.Key escrow and certificate management problems were solved by utilizing certificateless encryption system.Keyword ciphertext authentication was ensured by using digital signature technology.The security analysis results show that the proposed scheme can resist internal keyword guessing attacks under the random oracle model.Simulation results show that the proposed scheme has higher computational efficiency compared with similar schemes.…”

Panoramic video coding based on spherical distortion with spatio-temporal dependency by Xu YANG, Ce ZHU, Hongwei GUO, Lei LUO

“…The planar coding distortion, which affects objective quality, and spherical distortion, which affects subjective quality, as well as existing independent rate-distortion optimization techniques that fail to consider the temporal propagation of spherical distortion and its impact on coding performance, result in coding performance degradation.To address these issues, a spatio-temporal dependent spherical distortion model was proposed for optimizing panoramic video coding.Firstly, a spatial mapping model was proposed to map spherical distortions to coding distortions, aiming to align subjective and objective quality assessments.Secondly, a temporal propagation model for spherical distortions was introduced to enhance the overall coding performance of all coding units in the propagation chain.Finally, the coding parameters were adjusted by computing the weights for spatial mapping and temporal propagation of spherical distortions.Experimental results demonstrate that, under low-delay encoding configurations, compared to the VTM14.0, a state-of-the-art video coding benchmark, the proposed algorithm achieves an average bitrate savings of 7.4% (up to 22.1%) and reduction in coding time of 9%.…”

HARQ scheme for sparse code multiple access based on network coding by Ke LAI, Jing LEI, Wei LIU, Lei WEN

“…To fulfill the stringent reliability and throughput demand of the beyond-5G and the forthcoming 6G, a novel network coding (NC) based hybrid automatic retransmission request (HARQ) for low-density parity check (LDPC) coded SCMA was proposed.Two incorrectly received packets from different time slots were retransmitted by using NC principle under multi-user scenario.By doing so, the information came from two packets could be conveyed in one retransmission.Moreover, extra coding gain could be attained at the receiver.Furthermore, since the similarity between SCMA detector and LDPC decoder, and the one check node feature of NC decoder, a SCMA, LDPC and NC joint decoder based on message passing algorithm (MPA) was proposed.The proposed scheme could fully utilize the soft messages come from current and previous transmissions, and thus exploiting satisfied coding gain from NC.Simulation results show that the superiority of the proposed novel HARQ scheme for SCMA over the conventional HARQ on both throughput and reliability.…”
