Aiming at the current deficiency of yellow and white lane line feature recognition, a method for rapid lane line calibration and detection recognition is proposed. The yellow and white lane line figures of the actual road are identified in LAB and LUV color spaces, and a quadratic curve model is established to restore the lane geometry model and provide a basis for rapid geometric positioning of the vehicle when the automatic emergency braking system algorithm is built. In order to handle with problems such as heavy calculation and low accuracy of vehicle target recognition, the deep neural network learning theory is analyzed, and a vehicle feature detection and recognition algorithm based on a convolutional neural network algorithm is built to detect and classify environmental vehicle targets. The network training recognition accuracy rates are up to 87.1%. The images of typical road conditions in South China were collected, and the network was tested and verified. The results show that the built environmental feature recognition algorithm can meet the requirements of accuracy and real-time performance.","PeriodicalId":397407,"journal":{"name":"2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133961820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, artificial intelligence technology has made great achievements in many fields, and equipment fault diagnosis is also very prominent. As the working environment of the floating fan unit is bad and far away from the land, once the floating fan unit generator fails, it may have very serious consequences. Based on the research results of artificial intelligence technology, this paper focuses on the application of artificial intelligence technology in the fault diagnosis of floating wind turbine generator, and proposes an intelligent fault diagnosis system framework.

The mixed teaching method was applied to analyze students' personal big data. Teachers need to use computer data to adjust teaching decisions, and students use these data to reflect on themselves. The teaching mode of cloud class is closely related to computer algorithms and control engineering. Only by fully understanding students' individual learning behavior can teachers objectively evaluate students' formative assessment. The use of computers for in-depth understanding of group students' class participation helps teachers to realize personalized teaching. To sum up, the learners' living and learning holographic data will help students to improve their self-management ability. Therefore, this mixed teaching mode with computer as the medium can improve the scientific level of teachers' educational decision-making.","PeriodicalId":397407,"journal":{"name":"2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133892554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

STAR-CCM + was used to establish a cross-wind flow field simulation model for vehicles entering and exiting the tunnel, which was Co-simulated and analyzed with an 8-degree-of-freedom vehicle model. On this basis, an active front wheel steering (AFS) control system model was established and a comparative simulation was conducted. The simulation results show that under the condition of loading active front wheel steering (AFS), the parameters such as sideslip angle and yaw rate decrease obviously when the vehicle enters and exits the tunnel under the action of crosswind. The crosswind stability of the vehicle has been improved.","PeriodicalId":397407,"journal":{"name":"2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124191911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A method based on extended kalman filter is proposed for DC-SQUID optimum operating point automatic searching. This algorithm filters the noise in the measurement process in real time to make the result more accurate. The calculation does not require much historical data, and the amount of calculation is small. Taking the aviation full tensor magnetic gradient instrument as the application background, experiments show that the algorithm can effectively find the optimum operating point of DC-SQUID.","PeriodicalId":397407,"journal":{"name":"2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT)","volume":"36 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114566503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the second theorem and calculus theory of material mechanics, the formula of flexibility matrix of chamfering flexible spherical hinge is deduced by energy method, and an example is used to verify the results in finite element method. The error between theoretical solution and finite element solution is less than 10%, which verifies its correctness. The structural parameters affecting the flexibility are analyzed, and it is concluded that the flexibility increases with the length of the flexible spherical hinge or the chamfer radius R, but decreases with the increase of the minimum thickness and the angle between V type and x axis. And the change of the minimum thickness has the most obvious influence on the flexibility.","PeriodicalId":397407,"journal":{"name":"2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115039839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
