Train hibernation wakeup system and method

By introducing autonomous sensing units and sleep/wake-up units on the train to construct a triple independent position information source cross-verification mechanism, the problems of single position information and insufficient detection of environmental changes in the existing technology are solved, realizing safe wake-up without human intervention throughout the entire process, and improving train departure efficiency and system availability.

AI Technical Summary

Technical Problem

The existing train hibernation and wake-up schemes rely on a single source of location information, are susceptible to single-point failures, lack environmental change detection, and are highly dependent on manual intervention, resulting in safety hazards and low train dispatch efficiency.

Method used

An autonomous sensing unit is introduced to construct a three-fold independent location information source cross-verification mechanism. Combined with fingerprint collection in the dormant environment and fingerprint comparison during wake-up, a fully unattended secure wake-up process is achieved.

Benefits of technology

Triple cross-checking ensures accurate positioning, reduces labor costs, improves vehicle dispatch efficiency, and prevents safety accidents caused by location changes or intrusions.

Abstract

This invention pertains to the field of rail transit train operation control technology, and particularly relates to a train hibernation and wake-up system and method. The train autonomous protection system receives a hibernation command, calculates the train's position, and stores it in its own memory to form first position data. An autonomous sensing unit collects real-time environmental data and forms third position data based on this data. The system also receives and stores the train's position to form second position data. During the train wake-up process, the autonomous protection system reads the first position data, the second position data, and receives the third position data, and cross-compares these three data. If at least two of the data match, the train position is considered valid, and the wake-up process continues; otherwise, the wake-up process is terminated, and fault information is reported. This invention's technical solution uses cross-verification from three independent sources to avoid single-point failures leading to position errors, thus improving wake-up security and system availability.
