In modern industry, ball bearings are not prone to failure, once a failure occurs, the production of the factory will be shut down, which will cause economic losses. Therefore, it's crucial to research how to diagnose ball bearings. This research proposed an advanced fault diagnosis method: 1D-CNN-LSTM to classify ball bearing faults and use the ball bearing faults data from Case Western Reserve University (CWRU) to execute experiments, which is the raw one-dimensional vibration sequential data. In the experiment, the raw vibration data is first split into multiple subsequences, and input to one-dimensional convolutional neural network (1D-CNN) wrapped by TimeDistributed layer to extract features. The output of 1D-CNN is a sequence, which is input to long short-term memory (LSTM) for sequential processing. Finally, the class of bearing fault is output for diagnosis. The results indicate a good model fit and outstanding generalization and robustness on new validation data. The assessment of the training dataset indicates that it has achieved a perfect accuracy of 100%, while the validation dataset has achieved an accuracy of 99.99%, which is an exceptional outcome.
在现代工业中,滚珠轴承不容易发生故障,一旦发生故障,工厂的生产将停止,这将造成经济损失。因此,研究滚珠轴承的故障诊断方法至关重要。本研究提出了一种先进的故障诊断方法:1D-CNN-LSTM对球轴承故障进行分类,并利用凯斯西储大学(CWRU)的球轴承故障数据进行实验,该数据为原始的一维振动序列数据。在实验中,首先将原始振动数据分割成多个子序列,输入到timedidistributed层包裹的一维卷积神经网络(1D-CNN)中提取特征。1D-CNN的输出是一个序列,该序列被输入到LSTM (long - short memory)中进行顺序处理。最后输出轴承故障的类别进行诊断。结果表明,该方法对新的验证数据具有良好的拟合效果,具有较好的泛化和鲁棒性。对训练数据集的评估表明,它达到了100%的完美准确率,而验证数据集达到了99.99%的准确率,这是一个例外的结果。

Urban underground integrated pipe corridor is used for the water, electricity, gas, communications, and other pipelines into the underground space to effectively alleviate road traffic congestion, urban construction infrastructure, and other problems. After the completion of the corridor, the corridor inspection is a huge problem, as the underground space is complex and difficult to locate. For the need to detect the concentration of toxic and harmful gases inside the corridor, it is difficult to ensure the safety of the lives of the underground staff. With the development of artificial intelligence and digital twin, the corridor inspection robot gradually becomes the “perfect candidate” for inspection work. Thus, we present a system design of 3D LIDAR-based robot positioning and map building underground where GPS is not available.

Using the random forest algorithm in machine learning, the problem of children's social phobia is transformed into a classification prediction problem. There are many reasons for social anxiety disorder in childhood (SADC). Thus, we study the influence of parents' socioeconomic attributes on SADC. Based on the data obtained from the questionnaire survey of children and their parents in an early education institution, we build a prediction model between SADC and parents' socioeconomic attributes with the bivariate correlation method, the logistic regression, and the random forest method. The study result shows that the parents' socio-economic attributes are strongly related to SADC, and the model can be applied to the personalized care and psychological intervention of this early education institution. The result also shows that the accuracy reaches 80.5%. The model can be applied to preschool prediction and screening of children's social phobia tendencies and provides a reference for teachers to give personalized care and psychological intervention to children with a high tendency in follow-up teaching activities.

To improve the control accuracy of the quadruped robot, a method to estimate and control the attitude of the quadruped robot is presented using a nine-axis IMU sensor and kinematics model. An extended Kalman filter (EKF) is designed to filter the real-time data obtained from sensors such as a gyroscope, accelerometer, and magnetometer. After extended Kalman filtering, the nine-axis data of IMU is fused to obtain a more accurate quaternion. The quaternion is converted into the attitude angle to obtain the roll angle, yaw angle, and pitch angle of the quadruped robot. The filtered attitude angle is obtained by inversion to perform attitude compensation so that the quadruped robot can return to the normal attitude. After calculating the attitude compensation matrix, we solve the inverse kinematics of the quadruped robot to obtain the joint angle and understand the control of the quadruped robot's standing posture. The simulation results show that this method can effectively process the IMU sensor data and obtain a high-precision robot attitude angle. We will apply the above research results to the teaching of robot mechanisms for graduate students. The effectiveness of the algorithm is verified by the joint simulation of Matlab and CopperiaSim, and students have a further understanding of the quadruped robot attitude and control.
为了提高四足机器人的控制精度,提出了一种利用九轴IMU传感器和运动学模型对四足机器人姿态进行估计和控制的方法。一个扩展的卡尔曼滤波器(EKF)被设计用于过滤从传感器如陀螺仪,加速度计和磁力计获得的实时数据。通过扩展卡尔曼滤波,融合IMU的九轴数据,得到更精确的四元数。将四元数转换为姿态角,得到四足机器人的横摇角、偏航角和俯仰角。通过反演得到滤波后的姿态角,进行姿态补偿,使四足机器人恢复正常姿态。在计算姿态补偿矩阵后,求解四足机器人的运动学逆解,得到关节角度,了解四足机器人站立姿态的控制。仿真结果表明,该方法能有效地处理IMU传感器数据,获得高精度的机器人姿态角。我们将把上述研究成果应用到研究生机器人机构的教学中。通过Matlab和CopperiaSim的联合仿真验证了算法的有效性,使学生对四足机器人的姿态和控制有了进一步的了解。

In order to accurately identify and evaluate tennis movement, a method of tennis movement recognition and evaluation based on ResNet is proposed by combining computer vision with tennis movement-related knowledge. Firstly, the pose estimation model is used to detect the human target in a tennis video and extract the key points of the skeleton. Then, the ResNet model is trained using the video data set collected on the professional tennis court. The model can classify the sub-actions of tennis. A dynamic time-warping algorithm is used to evaluate the classified actions. A large number of experiments are carried out based on the collected video data set. The results show that the accuracy of the proposed ResNet-based tennis motion recognition method for the classification of 6 types of tennis sub-movements can reach 90.8%. Compared with methods based on graph convolution networks such as AGCN and ST-GCN, it has a stronger generalization ability. The proposed scoring algorithm based on dynamic time regulation gives the evaluation scores of corresponding actions in real time and accurately after the action classification, thus reducing the work intensity of tennis teachers and effectively improving the quality of tennis teaching.
为了准确识别和评价网球运动,将计算机视觉与网球运动相关知识相结合,提出了一种基于ResNet的网球运动识别与评价方法。首先,利用姿态估计模型对网球视频中的人体目标进行检测,提取骨架的关键点;然后,利用在专业网球场采集的视频数据集对ResNet模型进行训练。该模型可以对网球的子动作进行分类。采用动态时间规整算法对分类动作进行评估。基于采集到的视频数据集进行了大量的实验。结果表明,本文提出的基于resnet的网球运动识别方法对6种网球子动作的分类准确率可达90.8%。与AGCN、ST-GCN等基于图卷积网络的方法相比,具有更强的泛化能力。本文提出的基于动态时间调节的计分算法,在动作分类后实时准确地给出相应动作的评价分数,从而降低了网球教师的工作强度,有效地提高了网球教学质量。

In order to quickly select a book from a large number of books, a comprehensive method is proposed with an implicit semantic model based on matrix analysis and time effect according to the cognitive characteristics of university readers in different learning periods. This method uses the random gradient descent method to calculate the customer-project evaluation matrix. In the method, a new treatment method is provided for cold start. The absolute error (MAE) and the mean square relative error (RMSE) of the evaluation index are used to test the correctness of the information provided by the proposed method. The feasibility and effectiveness of this method are confirmed by the actual data.
