Research on Positioning Technology of Railway Site Safety Protection System Based on Beidou Positioning
In order to solve the problems that the traditional safety protection system for railway workers on the spot cannot know the location information of workers and trains in time and the lack of interaction of the protection status,in this paper,a security protection scheme based on BDS positioning technology is proposed.The scheme uses satellite positioning technology to real-time locate the position information of field workers and trains and transmit it to station management system.Through systematic analysis,the relevant information is transmitted to the hand-held terminal equipment of the operators on the spot,and the train early warning information is sent according to the actual situation,thus realizing the goal of safety protection.Based on STC15W4K56S4 microcomputer,a positioning data acquisition system is built to verify the accuracy of the positioning algorithm,with the aid of serial port debugging tool,the positioning accuracy of two high precision positioning algorithms-car-rier phase difference and pseudo-range difference is compared in the upper computer,it can reach centimeter level,fully meet the positioning requirements of safety protection for railway field workers.
