“…At this time, it is necessary to collect the voltage and current information of the micro grid common bus in real time. Furthermore, feed it back to the control strategy to adjust the output value of the grid connected inverter, so that the voltage and frequency in the micro grid system can continue to maintain stable operation at the rated value [7][8]. Therefore, in order to meet the above conditions, a new virtual synchronous generator control strategy can be used to control the grid connected inverter when the micro grid is in island operation.…”

“…General indoor wireless network positioning methods include infrared positioning, WiFi Positioning and ultra-wideband (UWB) positioning [7]. The characteristics of mobile positioning of indoor robots are shown in the table below: [2,9] [2, 29] low-grade weak UWB positioning method is a relatively cutting-edge wireless network technology. Its total broadband frequency exceeds 500MHz, and the duration of frequency signal is very short.…”

“…Its total broadband frequency exceeds 500MHz, and the duration of frequency signal is very short. Therefore, the positioning method has strong time discrimination, which determines that the absolute advantage of UWB positioning method over other positioning methods is that it has a high indoor positioning accuracy [8][9]. Considering the price and performance, UWB indoor wireless positioning method is used in the research of indoor mobile robot monitoring and positioning.…”

The objective of this study is to realize the monitoring, positioning and route planning of indoor mobile robot, so that the brain of indoor mobile robot can form the route planning map in different environments, and finally achieve the best route navigation of indoor mobile robot. In this study, the ultra-wideband (UWB) wireless network location method of indoor mobile robot is proposed with laser pulse ranging method to measure the positioning distance of indoor mobile robots. Secondly, the trilateral positioning method is used to measure the position of the starting node to several known ending nodes, to estimate the position of the starting node of the indoor mobile robot. Finally, gyroscopes and odometers are used to measure the rectangular and U-shaped motion of indoor mobile robots. The results show that the sampling frequency of 50Hz UWB wireless network is used to collect offline information about the mobile indoor robot. After the information data is processed, the measurement noise covariance matrix can be obtained, and finally, the expected target can be obtained, and the positioning distance measurement of indoor mobile robot can be realized. When the robot glides along the rectangular road with a starting point of (2.48, 2.15) and the U-shaped road with a starting point of (7.16, 6.31) at a constant speed, its UWB measurement values basically jump near the route. At the same time, there will be noise, and the density of the numerical results is relatively low, which means that the UWB can find a stable direction for the indoor mobile robot, but it is unable to measure the path angle deviation of the robot. The deviation angles of the robot rectangular route are 90°, 180°, 270° and 360° respectively. The deviation angle error of gyroscope will increase with the increase of robot moving time. The deviation angle errors of the rectangular and U-shaped routes measured by the odometer are kept around the 0 reference line, which indicates that compared with the gyroscope, the odometer can correct the angle by the specific calculation method when the angle deviation is large, so as to keep the error around the 0 reference line. The results can provide a practical basis for indoor mobile robot to monitor and locate accurately through wireless network.

The study is employed to reduce mechanical faults and improve the work efficiency of machinery. This paper adopts intelligent detection means and systematically detects the machinery faults. First, a new feature extraction method is used for the sparse automatic encoder that proposed to solve the problem of insufficient feature extraction of the informational fault of the equipment. Second, the binary tree support vector machine (SVM) is used to classify faults. Finally, the electronic circuit of the three-spot resistance welder's fault is detected to verify the reliability of the sparse automatic encoder. The research result shows that the use of sparse automatic encoders can enhance the robustness of non-Gaussian noise. At the same time, the convolutional neural network (CNN) technology is combined to perform edge noise reduction on its encoder. It can improve the feature extraction degree of electronic circuit information. The binary tree SVM can effectively classify mechanical faults and the results of output judgment whether the mechanical equipment is faulty or not. The automatic encoder is used to detect the fault of the three-spot resistance welder, and the fault detection result of the new detection method has higher accuracy and high reliability. The new fault detection method can efficiently detect mechanical faults and promotes the work efficiency of machinery, and ultimately the entire society.
