Abstract

Objective To achieve real-time temperature monitoring of BR (braking resistor) in metro vehicles without temperature sensor, a new temperature estimation method for this purpose without additional sensors is proposed. Method By analyzing the BR structure and heat dissipation process, a control body temperature model composed of BR unit and its cooling domain is established. Based on the law of energy conservation and Newton′s law of cooling, equations for the temperature of BR unit and the average temperature of the cooling air within the control body are constructed. According to the relationship between braking resistor value and temperature, the BR heating power is continuously updated and iterative calculations are performed to obtain BR real-time temperature. Finite element thermal simulations are conducted to obtain the BR temperature distribution under steady-state and transient conditions, validating the new BR temperature estimation method. Result & Conclusion By calculating BR heating power based on the DC (direct current) traction network voltage and the duty cycle of the chopper circuit, a software-only solution to substitute hardware is achieved, avoiding the need for additional sensors. This method, combined with the BR temperature estimation algorithm, enhances the reliability of BR temperature estimation. The temperature obtained using this new estimation method is consistent with the thermal simulation results based on Fluent software, with relative errors within acceptable limits, proving the effectiveness of the proposed method. The real-time BR temperature estimation method enables BR temperature on-line monitoring and can adjust the electric braking force command values of metro vehicles based on real-time temperature monitoring, thereby improving the reliability and safety of the traction drive system.

lamé system, nonlinear time-varying delay, quasi-stability, 35b40, 35b41, 37l15, 37n35, Analysis, QA299.6-433
Abstract

This article is concerned with the stability and dynamics for the weak damped Lamé system with nonlinear time-varying delay in a bounded domain. Under some appropriate assumptions, the global well-posedness and asymptotic stability are shown in the case where the delay coefficient is upper dominated by the damping one. Moreover, the finite dimensional global and exponential attractors have also been presented by relying on quasi-stability arguments. The results in this article is an extension of Ma, Mesquita, and Seminario-Huertas’s recent work [Smooth dynamics of weakly damped Lamé systems with delay, SIAM J. Math. Anal. 53 (2021), no. 4, 3759–3771].

Abstract

Although traditional machine learning based methods for predicting mine internal caused fire have certain predictive capabilities, they cannot effectively capture global dependencies between complex multivariate data, resulting in low prediction precision. In order to solve the above problems, a transformer based time series prediction method for mine internal caused fire is proposed. Firstly, the Hampel filter and Lagrange interpolation method are used to detect outliers and fill in missing values in the data. Secondly, the self attention mechanism of Transformer is utilized to extract features and predict trends from time series data. Finally, by adjusting the size and step size of the sliding window, the model is trained in different time dimensions at different time steps and prediction lengths. Combining gas analysis method, the iconic gases generated by mine fires (CO, O2, N2, CO2, C2H2, C2H4, C2H6) are used as input variables for the model, with CO as the target variable for model output and O2, N2, CO2, C2H2, C2H4, C2H6 as covariates for model input. Selecting the bundle data of S1206 return air corner fire warning in Ningtiaota Coal Mine of Shanmei Coal Group for experimental verification, the results show the following points. ① Univariate prediction and multivariate prediction of CO show that multivariate prediction has higher prediction precision than univariate prediction, indicating that multivariate prediction can improve the prediction precision of the model by capturing the correlation between sequences. ② When the time step is fixed, the prediction precision of the Transformer based mine internal caused fire prediction model decreases with the increase of prediction length. When the prediction length is fixed, the prediction precision of the model improves with the increase of time step. ③ The prediction accuracy of the Transformer algorithm is improved by 7.1%-12.6% and 20.9%-24.9% over the long short-term memory (LSTM) algorithm and recurrent neural network (RNN) algorithm, respectively.
