AI Technical Summary

Technical Problem

In existing rail transit systems, emergency unlocking devices for train doors are prone to over-reaction due to passenger misoperation, affecting operational efficiency. They lack effective discrimination mechanisms, have poor interactivity, consume a lot of resources, and cannot execute differentiated safety responses.

Method used

A hierarchical authorization mechanism is introduced, and the train status is judged in real time through the signal system. Combined with multimedia linkage confirmation and human-machine interaction indicator lights, an intelligent decision-making and multi-system linkage safety control mechanism is constructed to achieve differentiated response to emergency situations.

Benefits of technology

While ensuring the safety of emergency evacuation, we can effectively identify misoperations, reduce interference with normal operations, improve operational efficiency and safety, and ensure the accuracy and reliability of decision-making through dynamic safety delay and secondary confirmation mechanisms.

Abstract

This invention relates to a method, system, device, and medium for controlling emergency unlocking of train doors. The method uses a signal system to determine the train's status in real time. When a high-risk scenario is identified, a tiered authorization process involving the control center is triggered. This is combined with multimedia-linked confirmation, configurable evacuation protection zones, and human-machine interface indicators to construct a safety control mechanism integrating intelligent decision-making and multi-system linkage. This effectively identifies and avoids erroneous emergency door unlocking operations while ensuring emergency evacuation safety. Compared with existing technologies, this invention has advantages such as effectively preventing misoperation and improving operational safety and efficiency.
