The time that people fail to cure in time due to sudden diseases in society occurs frequently. Therefore, based on this kind of phenomenon, this paper combines fall alarm and Beidou positioning, and designs a new type of fall detection system with STM32 single chip microcomputer as the main control chip, which uses ADXL345 tilt sensor for fall detection, buzzer alarm and remote alarm by sending real-time information through GSM module, so as to timely cure users. In addition, the smart bracelet also has the function of detecting human body temperature and heart rate, and can conduct real-time monitoring of physical conditions. This paper introduces the design idea, hardware selection and software design of the intelligent bracelet, completes the circuit diagram and flow chart of each module, makes the real object and completes the function test, and the results show that the designed product can achieve the preset function. Finally, the paper summarizes the existing shortcomings and prospects for the future of the smart bracelet.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"3 2","pages":"131630Y - 131630Y-6"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141385694","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}

This paper proposes a wind power interval prediction method based on temporal data soft clustering and similarity measurement (SCSM). First, a soft clustering module is used to cluster wind power data with probabilities. Next, a similarity measurement module assesses the similarity between wind power data based on soft clustering results and generates probability interval predictions by referring to historical prediction errors. Finally, the effectiveness of the proposed method is validated using real wind power data.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"51 1","pages":"131633P - 131633P-6"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381768","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}

This paper proposes a model for estimating system power deficit following a disturbance to predict the minimum frequency in power systems. Building upon the traditional average frequency response model, the model calculates the frequency variation rates for each generator 2 ms after a disturbance to estimate the power deficit for each generator. The entire system's generator inertia constant (H) and power deficit (P) are equivalently represented. Utilizing the governor model and rotor motion equations, a mathematical model for frequency prediction is developed. Finally, based on the boundary conditions at the moment of the appearance of the minimum frequency, the minimum frequency is determined. Simulation results from a three-machine nine-bus system in PowerFactory are compared, demonstrating that the proposed algorithm can rapidly and accurately compute the minimum frequency after a disturbance occurs in the system.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"3 6","pages":"131634P - 131634P-6"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141383808","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}

Firstly, the optimized guided filter algorithm is applied to the preprocessing of gear image, which improves the quality of image processing. Then the gradient values in eight directions are calculated, which makes the interpolation of non-maximum suppression more refined than the original algorithm. Finally, based on OTSU algorithm, the gray-gradient mapping function is constructed to determine the optimal threshold, which solves the limitation of the original algorithm to determine the threshold manually by experience. The experimental results show that the quality factor of the edge detection results of the proposed improved Canny algorithm reaches 0.868. Compared with the original Canny algorithm, the quality factor performance is improved by 13.51%, which proves the effectiveness of the improved measures proposed in this paper.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"90 7","pages":"131635Z - 131635Z-6"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384951","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}

During daily use, local coating detachment may occur on the surface of the equipment due to collision and wear, making it difficult for manual operation to reach. Therefore, specialized equipment is needed for coating repair work. In order to meet the requirements of complex surface working conditions and have the functions of checking the surface coating status, determining the repair position, polishing the repair position, and repairing the paint, a surface walking and climbing robot based on permanent magnet adsorption is proposed. This article carried out the design, manufacturing, and final assembly of a coating repair climbing robot, and completed the process validation test of the prototype. The experiment shows that the wall climbing robot using permanent magnet adsorption technology can reliably adsorb in places where the working surface is made of ferromagnetic materials such as steel. Image recognition, surface polishing, coating repair, etc. basically meet the requirements of use, effectively improving work efficiency.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"9 4","pages":"131638M - 131638M-7"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141385159","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}

However, in the current CAD/CAM system, the processing of tool electrodes is done manually by technicians based on their experience and knowledge, which is very dependent on their professional skills and experience, and also unable to reuse the process, resulting in a large waste of process resources. To solve this problem, an intelligent CNC programming method for tool electrode is proposed, which organizes the historical machining cases of tool electrode to form a CNC parameter dataset, and then constructs a GA-BP network model to train and determine the CNC parameters required in the machining process, and finally generates the machining toolpaths of tool electrode in NX software. The experimental results prove that the integration of GA-BP neural network can effectively reuse the resources of manual programming process of tool electrode, reduce the dependence on technicians' professional skills, and promote the development of tool electrode machining programming in a more intelligent direction.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":"29 10","pages":"131637R - 131637R-7"},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141382623","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}
