Particulate environment is frequently encountered in the millimeter wave propagation path. The particles usually produce scattering and absorption to the millimeter wave. Unfortunately, these particles usually have different size, ingredients and even a mixture of many elements. This paper presents a preliminary study of the attenuation of particles on millimeter wave transmission. The dielectric property of water sand and ice were also discussed. The study was conducted at 110 GHz and 220 GHz. Calculation was based on the Mie theory. A full wave simulation was also conducted to better understand the attenuation effect.

IEEE International Conference on Unmanned Systems (ICUS)

Currently, the prevailing approach in pedestrian detection involves leveraging deep learning techniques. However, effectively detecting pedestrian objects at small scales continues to pose a significant challenge in this field of research. Moreover, many algorithms prioritize accuracy improvement, making it difficult to deploy them in real-world scenarios. This paper proposes an edge device-friendly object detection method. We introduce a target extraction module with a minimal number of non-linear units to preserve fine-grained information in the network. Additionally, we design a trapezoidal FPN structure based on the structural re-parameterization technique, and optimize it specifically for edge devices. Furthermore, we construct a hardware platform to validate the feasibility of our algorithm in real-world applications. In the experimental section, we demonstrate that our proposed method outperforms comparative algorithms on the Caltech pedestrian dataset, while maintaining high speed on edge devices.

In order to improve the endurance of unmanned aerial vehicles (UAVs), a power supply controller with automatic switching between solar energy and battery was designed. The controller is mainly composed of an AT89C51 single chip microcomputer. By collecting ambient light intensity and comparing it with the preset light intensity of the system, the controller completes automatic switching of the power supply for solar unmanned aerial vehicles, thereby achieving continuous and stable power supply for solar unmanned aerial vehicles. In addition, the implementation method of the single-chip microcomputer program in the controller is also introduced. The control core is to use Schmidt de shake control to switch between solar energy and battery, and to test the various functions of the controller through the flight experiment of a small solar powered unmanned aerial vehicle. Tests have found that solar powered drones using this controller can navigate for a long time in weather with varying light intensity, and the device operates well, effectively improving the power stability of solar powered drones. © Published under licence by IOP Publishing Ltd.

In order to solve the bounding box deviation while the object moves rapidly, which will cause the loss of the object, an improved Kernelized Correlation Filter object tracking algorithm is proposed based on motion estimation. The block-matching algorithm is used to estimate the motion of the tracking object in the adjacent frames of the video sequence, and the estimated results are quantified to judge the severity of the object’s motion. Then the size of the search box is adaptively adjusted. Two data sets of both OTB100 and OTB50 are selected for the experiments. The experimental results show that the improved algorithm can effectively solve the problem of object loss caused by rapid object movement and achieve long-term stable tracking of objects.

In order to improve the utilization efficiency of solar energy, based on the in-depth study of the characteristics of solar energy, a control scheme based on daily motion trajectory was designed. In this scheme, single chip microcomputer is used as the controller to realize the output of SPWM waveform, and the compound PID with multiplexing selection is used to control the Angle of solar panel, so as to achieve the effect of fast and sensitive tracking of solar illumination. Through the angle sensor, on-line monitoring of the angle data of the solar panel, according to the intelligent control optimization algorithm, combined with single-chip microcomputer control technology, a more optimized control scheme is proposed. The experimental data show that the design effect is good and the expected control goal is achieved.

作者： Zhuanzhe Zhao Guowen Ye Yongming Liu Zhen Zhang School of Mechanical Engineering Anhui Polytechnic University Anhui Provincial Engineering Laboratory on Information Fusion and Control of Intelligent Robot Wuhu China School of Mechanical Engineering Anhui Polytechnic University Wuhu China

In order to accurately evaluate the working state of RV reducer, a fault identification method based on the fault identification model established by Self-Organizing Feature Map (SOM) Neural Network is proposed. Firstly, the data measured by the RV reducer test platform are analyzed by wavelet to obtain the wavelet coefficient. Then, combined with the efficiency data of RV reducer, the mean square frequency, center of gravity frequency and frequency variance of the two groups of data are calculated after Fourier transform and power spectrum analysis. After optimization, several eigenvalues are obtained. The eigenvalues are input into the competitive neural network and SOM neural network to establish the fault identification model. Finally, the results of the fault identification model established by the competitive neural network and SOM neural network are compared. The prediction results show that the fault identification model established by SOM neural network can effectively determine the working state of RV reducer.

Method for robot Capturing Object Thrown out in Natural Wind Environment

引用

Journal of Physics: Conference Series 2021年第1期1828卷

作者： Rui Zheng Chuanchao Zhao Jun Kang Zibao Lu School of Physics and Electronic Information Anhui Normal University Wuhu 241002 China School of Instrument Science and Engineering Southeast University Nanjing 210096 China Anhui Provincial Engineering Laboratory on Information Fusion and Control of Intelligent Robot Wuhu 241002 China College of Automation Engineering Nanjing University of Aeronautics and Astronautics Nanjing 210016 China

It is difficult for a robot to capture object which is thrown out in the environment with natural wind. Equation of state and measurement of the object in the environment with natural wind is studied. Using the measurement equation and the state equation when there is no natural wind, the average acceleration of the object caused by natural wind can be estimated. Moreover, the variance of the object acceleration caused by natural wind can be estimated using the statistical characteristics and probability distribution of natural wind. Then a method for robot capturing the object based on Kalman filter is proposed. Simulation results show that the trajectory of the object changes obviously when two groups of typical natural wind are used. The object trajectory can be tracked by the robot accurately after it deviates from the object trajectory for about eight sampling periods.
