Description

technical field [0001] The invention relates to the technical field of train operation control technology, in particular to an autonomous train operation system based on UWB distance measurement. Background technique [0002] Compared with other countries in the world, my country has a vast territory, various terrains, and various weather and environments are very complex. The existing train operation system of the railway lacks the ability of train autonomy and automation, and the general train operation system is difficult to adapt to regions and weather. . For example, in mountainous areas, trains using GPS technology cannot always receive GPS signals; trains using microwave or shortwave communication cannot guarantee the normality of communication in unexpected situations. [0003] Ultra-wideband pulse has the advantages of high ranging accuracy, strong penetrating ability, high resolution ability, good anti-stealth ability, and low power consumption. In recent years, n...
