Development of a diagnostic procedure for assessing the performance of a magnitoplane navigation system

The object of research is the process of ensuring the reliability of high-speed magnetic levitation. Navigation tasks of high-speed ground transport require high accuracy and reliability along with high speed of obtaining data on the location of the magnetic levitation. The problem to be solved is to ensure the integrity of the magnetic levitation navigation system by means of essential integration into its structure of the diagnostic subsystem, the basis of which is the phase ranging method. It has been established that the diagnostic procedure for determining the operability of the navigation system of a high-speed vehicle in real time is fully ensured by the use of the phase ranging method. A method of continuous precision positioning of a high-speed magnetic levitation vehicle based on the phase ranging method for an arbitrary configuration in three-dimensional space of a fixed track structure, as well as a method of ensuring the integrity of the navigation system of a maglev train, has been substantiated. A new approach to solving the location problem is proposed, which allows using the train communication channel with the traffic control center as a distributed location sensor as an integral element of the radio wave information and control system. The structure of the information packet cycle is proposed. The volume of the information flow and the degree of redundancy introduced into the information flow to ensure the required reliability of information transmission are determined. The developed diagnostic procedure meets the requirements for the safety and reliability of operation of high-speed ground transport based on magnetic levitation technology, the movement of which is controlled using a navigation system topologically connected with the configuration of the track structure.
