Sichuan power grid has a large number of transmission lines in the complex terrain, which’s communication is blocked. Inspection of transmission lines is often difficult and risky. Because the beidou satellite communication system is not affected by geographical environment and limit of communication network station, handheld mobile inspection terminal based on beidou communication implements real-time two-way short message communication, automatic navigation and positioning, SOS distress, and other functions in no man area. The terminal is helpful for the real-time intelligent recording circuit status in the transmission line patrol, guaranteeing the personal safety of the inspection personnel and improving the efficiency of the grid management system, which is of great application value.

In this paper, an accurate Gaussian sum-filtering method is developed theoretically and tested experimentally for the continuous-discrete nonlinear systems with non-Gaussian noise. The state dynamics of the systems are modeled with nonlinear Itô-type stochastic differential equations (SDEs) and the measurements are obtained at discrete time instants with non-Gaussian noise. We first show how the recently developed accurate continuous-discrete extended-cubature Kalman filter (ACD-ECKF) can be applied to classical continuous-discrete Gaussian state estimation. Then, we derive the square-root version of the Gaussian sum-ACD-ECKF for continuous-discrete models with non-Gaussian noise. The Gaussian sum-filter applies a bank of parallel ACD-ECKFs to approximate the predicted and posterior densities as a finite number of weighted sums of Gaussian densities and the corresponding weights are obtained from the residuals of ACD-ECKFs. The performances of the proposed method are compared with the recently presented filters based on the Maximum Correntropy Criterion (MCC) in a simulated application and the numerical results show that the presented approach is more accurate and robust than other algorithms.

Universal-filtered multi-carrier (UFMC) is a novel multi-carrier modulation technique for 5G wireless communication, which is suitable for short packet and low latency transmissions. In addition, UFMC has a lower sensitivity to synchronization errors compared with orthogonal frequency division multiplexing (OFDM), however synchronization is still an important problem for UFMC-based systems. In this paper, a new preamble structure based on Zadoff Chu (ZC) sequence is devised first for UFMC based systems. Then, an efficient carrier frequency offset (CFO) estimation scheme based on the preamble is proposed. The scheme is primarily divided into two steps. To begin with, based on Maximum likelihood (ML) algorithm, a coarse carrier frequency offset estimation approach is expounded and the searching step of this approach is discussed for a relatively simple calculation. Next, according to the preamble structure, compensated preamble is correlated for fine residual CFO estimation. Through numerous simulations, it is verified that the scheme has a large estimation range and accurate CFO estimation in multipath fading channels.

At present, the static thermal rating (STR) used for overhead wires is calculated under the assumption that relatively unfavorable meteorological conditions occur simultaneously, which limits the efficient forthputting of transmission lines to a certain extent. Therefore, this paper proposes a calculation method to analyze the daily distribution of thermal rating driven by meteorological data to release the load capacity of the transmission line. Firstly, the distribution of thermal rating at daily time scales is calculated based on IEEE738, and then the distribution of ratings can be counted by Parzen-window technology. Then, the static thermal rating can be converted into the seasonal, monthly or daily values, as the time scale of the thermal rating is shortened. Finally, the operational risk assessment is evaluated combined with the actual operating parameters of the wire. The example shows that the proposed method can determine the appropriate thermal rating conveniently at daily time scale according to the allowable operational risk of the power system, as well improve the load capacity of overhead lines.

In wireless positioning, the time delay due to non-line-of-sight propagation will significantly reduce the localization accuracy of traditional algorithms. Therefore, this paper proposes a two-step constraint least squares (CLS) algorithm, in which a new range constrain is constructed with the help of coarse positioning estimation, while the coarse estimation is produced by the conventional CLS scheme. Consequently, the quadratic programming scheme is operated to enhance the final localization performance. Simulations demonstrate that the proposed algorithm greatly enhances the localization accuracy in the NLOS environment, and outperforms the tested opponents. Moreover, we also observe a stable performance of the proposed algorithm in terms of the measurement noise variations.

In order to solve the problems of the complicated structure and the short life of quantitative systems for acupuncture manipulations, a new quantitative method based on electromagnetic induction was proposed in this paper. In this method, the exciting coil and the induction coil were sensing elements, and the time domain parameters of the induced voltage were quantitative indicators. It can perform the lifting-inserting deepness, the entwisting frequency and manipulation time accurately. The feasibility of this method was verified by simulation, and the quantitative system was designed. In this paper, the lifting-thrusting and entwisting manipulations were chosen to do controlled experiment between experts and novices. Statistical methods are used to analyze the voltage variance in time domain. The experimental results show that coefficients of dispersion of experts are lesser than those of novices and the time of voltage rise, voltage fall and total manipulation time are lower than those of novices. The research results show that this method can accurately quantize the acupuncture manipulations. It will provide a scientific and normative standard for the acupuncture manipulations.

With an eye to solving the problems on lack of the sample and low accuracy in analog circuit fault diagnosis, one effective method based on the Sine Cosine Algorithm(SCA) is proposed for soft fault diagnosis in analog circuit with tolerance. Primarily, monte carlo analysis is performed on the experimental circuit and then the output voltage signal collected as dataset. Then the wavelet entropy is calculated from dataset transformed by the wavelet transform, which forms the fault feature dataset. The principal component analysis(PCA) is used for lowering the feature dimension. Finally, support vector machine(SVM) optimized by SCA is employed for classification of the fault dataset. Experiment on the Sallen-Key band-pass filter circuit analysis shows that the SCA-SVM classifier has higher classification accuracy and faster iteration speed than GridSearch, Genetic Algorithm and Particle Swarm Optimization. Verification experiment on the four-opamp biquad highpass filter circuit indicates excellent adaptive capacity in analog circuit fault diagnosis.
