Abstract

The present invention provides a method and system for speed measurement and positioning of a moving object based on multi-source information fusion. Multiple speed measurement and positioning devices are used to collect information related to the running state of the measured moving object at the same time to obtain various collection state quantities, and then by constructing The federal Karl filter model is used to fuse each of the collected state quantities to obtain the final fusion state prediction measurement of the operating state of the moving object. The advantages of each device are complemented by each speed measurement and positioning device, so that the entire speed measurement The accuracy of the positioning system.

Description

technical field [0001] The invention belongs to the technical field of train speed measurement and positioning, and particularly relates to a speed measurement and positioning method and system for moving objects based on multi-source information fusion. Background technique [0002] With the rapid development of my country's transportation industry, the railway transportation industry represented by high-speed and heavy-duty trains has become a pillar industry in my country, and it is a comprehensive manifestation of my country's progress towards a world modernized scientific and technological power. Among them, the maglev train, as an advanced form of rail transportation, is one of the future development directions of high-speed railways in my country and even the world. In the process of daily railway operation, the accuracy and reliability of the real-time position and speed information provided by the train speed measurement and positioning system for the train not only...
