Overcrowding alarm detection of trackless rubber-tyred vehicle based on precise positioning technology
摘要
Abstract
Aiming at the problems of missing identification of passengers caused by excessive moving speed of underground vehicles and shielding of vehicle casings,the inability to effectively control the overload of vehicles,the existence of potential safety hazards,and the difficulty in meeting the relevant requirements of the auxiliary transportation system in Intelligent Demonstration Coal Mine Acceptance Management Method(Trial Version),a trackless rubber-tyred vehicle overcrowding alarm detection method based on precise positioning technology is designed.Firstly,the ranging data output by the base station is converted into three-di-mensional coordinates to generate a continuous trajectory.Secondly,the moving direction vector is determined by using the position data of adjacent moments,and then the trajectory data is filtered.Thirdly,the dynamic time warping(DTW)algorithm is used to align the trajectory of the vehicle and the passenger,solve the optimal path,and obtain the measurement value.Finally,the driver's trajectory measurement value is taken as a sample to measure the similarity between the personnel trajectory and the sample,and then the judgment of whether the personnel is the passenger and whether the vehicle is overcrowded is obtained.The experimental results show that the functions are running normally,the correct rate is about 95.12%,the corresponding logic time is about 30 ms,and the field application is in good condition.关键词
