通过将语义通信技术引入工业网络,构建了一个面向工业互联网的语义编码传输系统。系统中设计了语义编解码器以提取信源中的语义信息,相对于传统通信系统,基于语义信息的通信有更高的信息压缩效率与更高的符号差错容忍能力。同时引入信源信道联合编解码器,以信源信道联合编码的方式将语义信息转化为信道符号传输,进一步提升系统对工业网络通信资源的利用效率。所有编解码器均构建在深度神经网络架构Transformer上,确保了编解码器对语义信息的理解能力及系统的泛化能力。在工业药品生产场景中,对该系统进行测试,结果显示:相较于传统通信方案,该语义编码传输系统在图像重建质量和传输处理速度方面均有显著提升。且系统对下游任务的性能影响极小,保证了工业生产中如缺陷检测等关键任务的准确性。

针对电动汽车车载充电机的设计过程中普遍存在的电磁干扰频率范围广、干扰源复杂的问题,提出了一种基于端口阻抗测试的等效电路建模和系统级协同仿真方法。首先,通过对车载充电机系统各部件进行阻抗测试和三维电磁仿真,建立了无源器件、端口滤波器和高压屏蔽线缆模型,提取了系统印制电路板关键回路的高频寄生参数。其次,建立了有源器件的仿真电路模拟器等效模型,并通过双脉冲实验验证模型的精度;针对功率因数校正电路控制环节的仿真与建模难以同步实现的问题,采用协同建模的方法构建整个系统的等效电路模型。最后,将各部件模型组合在一起,建立了完整的车载充电机系统传导电磁干扰预测模型,并依据相关测试标准进行了系统传导电磁干扰仿真和实验。结果表明:在150 kHz~30 MHz频率范围内,预测结果与实际结果的误差小于9 dB,具有良好的一致性,表明该模型能够精确预测车载充电机系统高压交流端的传导干扰水平,可以有效指导充电机系统的电磁兼容正向设计。

为提高高抽巷的稳定性,本文采用数值模拟的手段分析了S1302高抽巷在开挖过程中的支承压力分布规律,采用分段掘进的方法共计掘进了3次。研究结果表明,高抽巷在开挖过程中,左右两侧的侧向支承压力分布特征并不相同。在靠近实体煤一侧,侧向支承压力随距离增加逐渐缩小。在靠近回风平巷一侧,侧向支承压力随距离增加迅速下降,当超过S1302回风平巷影响范围后,侧向支承压力逐渐增加至原岩应力,然后保持不变。

This paper studies the 3-D turbulent channel flows over rough walls with stochastic roughness height distributions by using the large eddy simulation and the immersed boundary method. The obtained mean and fluctuating velocity profiles for the smooth and rough channel flows agree well with the available numerical and experimental results. The stochastic surface roughness is found to have a more significant influence than the uniform surface roughness on the turbulent velocity statistics and the coherent structures, with the same average roughness height. With a greater variation in the roughness height, the mean velocity and the streamwise fluctuating velocity is decreased and the spanwise velocity and the wall-normal fluctuating velocity are increased. In addition, one observes larger and more profuse quasi-streamwise vortices, hairpin vortices and elongated structures above the crest plane of the roughness array in cases of highly stochastic rough walls. However, the low-speed streaky structures are broken up locally and the ejection and sweep events are depressed by the stochastic roughness below the average roughness height. The results of this study support Townsend’s wall-similarity hypothesis for both stochastic and uniform rough wall turbulences, demonstrating that in both cases the effects of the surface roughness on the turbulent flow are limited to the rough sub-layer.
