Problems solved by technology

[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 normal communication in unexpected situations

Abstract

The invention discloses an autonomous train operation system based on UWB distance measurement, which includes a signal processing unit, a communication module, a train control unit, a wheel shaft speed module and a radar speed measurement module. The input end of the processing unit is electrically connected, the output end of the signal processing unit is electrically connected to the train control unit, and the signal processing unit is electrically connected to the communication module, the communication module is connected to the server through a wireless signal, and the signal processing unit is connected to UWB ranging module, the UWB ranging module includes a UWB generator, a baseband, a microprocessor and a UWB antenna. The autonomous train operation system based on UWB distance measurement of the present invention has low energy consumption, high distance measurement accuracy, and strong signal penetration capability. Multiple corrections can be used to realize positioning and distance measurement in the case of weak signals, thereby ensuring the accuracy of autonomous operation. sex.

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...
