TH3977A - Train accident prevention system - Google Patents

Abstract

The automated railway accident prevention system continuously controls trains by transmitting signals along the track. These signals relate to speed limits, obstructions on the track, etc., or may replace railway side signs for train control. Therefore, it is crucial to ensure the train receives the correct signals and not transmit them to other trains. This is achieved by establishing a predetermined sequence of signal frequencies along the track and installing equipment in the train to monitor this sequence as it travels. This ensures train safety and system stability. If a train detects an unusable frequency sequence, the emergency braking system will activate immediately, or the train may be allowed to continue moving at a reduced speed.
