| Abstract:The safe operation management platform for heavy haul railway train inspection based on Beidou high-precision positioning is designed, realizing the accurate positioning of train inspection vehicles and personnel and reducing the risk of train inspection operation. The basic layer of the platform obtains the train inspection data through the infrared video acquisition equipment based on FPGA and the terminal equipment based on Beidou high-precision positioning technology, and transmits the data to the support layer through the networks of the transmission layer. With the support of the technologies such as high-precision electronic map vectorization processing and real-time differential dynamic positioning of the support layer, the train inspection target recognition module of the application layer calls cstx wavelet fusion algorithm to analyze Beidou satellite signals, The Hausdorff distance method is used to realize the target identification of train inspection operation. The train inspection operation safety early warning module calls the vectorization processing high-precision electronic map, and generates an electronic fence in combination with the daily train inspection operation plan to realize the safety early warning of operators. The service layer management personnel realize the management and maintenance of the platform. The experimental results show that the platform can realize the identification, accurate positioning and safety warning of train inspection targets. |
